RJ 45 Outlet for twisted pair. Independent crimping network socket RJ45

Internet access has long been an ordinary business for a modern person. For simultaneous use world Wide Web several gadgets, of course, is just one router providing wireless communication Wi-Fi, but to connect it to install the Internet socket. In the article, we will tell about connecting the Internet socket, consider step-by-step instructions.

This procedure differs from the installation of a conventional connector, because the design of the device is different and the principle of its operation has nothing to do with a 220V power supply point. However, possessing the necessary information and skills with electrical appliances, the user will completely be able to make installation.

Features Construction Online Sockets

The described products are passive network equipment intended for switching services to local networks With the help of special disconnectors. Like conventional outlets, an Internet connection devices, called RJ-45, can be outer (overhead), installed on top of the plane and internal (cut), mounted inside the wall.

Internal socket for internet connection, painted in dark color

The main components of the computer connector are:

the front side is a decorative panel with a patch cord nest;
reverse (internal) part is essentially terminal with contacts for wires from the Internet cable.

In the outlet is introduced network cable "Twisted pair", which contains four twists in two wiring in each. They are divided into eight conductors who have different colors.

Appearance and internal device network Internet Wires "Twisted Couple"

Each conductor connects to the corresponding socket contact according to a specific scheme. This compound is called crossing. Its execution is described in more detail in the next section. Wires are two-party and four-party. The first are used in networks where the signal transmission occurs at a rate of less than 1 GB / s. But in our speed century, everything quickly changes and the data flow in the worldwide network can very soon to achieve values \u200b\u200bin several gigabytes per second. Therefore, it is better to use four-room products, designed for speed up to 10 GB / s to avoid subsequently alterations.

Installation and connection of the power outlet

The wire twisted pair is placed in the cable channel or closed by a plinth. The free end is displayed through the peavern, the outside (when installing a mortise model) or is left uncovered (if the invoice is mounted). Its length is sufficient to exercise necessary work. From the very edge, 7-8 cm retreats and the outer shell from this site is removed. Conductive pairs are spinning, separated and straightened. Next steps Led into instructions.

Step-by-step instructions for connecting RJ-45 with four pair wire

Crush the wires in the terminals of the socket according to the selected option (the color of the wire coincides with the color of the contact). For example, as shown in the picture, from left to right: brown, white-brown, green, white and green, orange, white and orange, blue, white-blue. The order of the crimping is better to consider a separate item for this publication.

Fix the clamp wire and pre-check the signal transmission through the connector. To do this, in the disassembled device, connect the connector from the tablet, laptop or mobile phone and make sure that there is a connection with the Internet
Crop the excess wiring. Collect the socket by connecting both parts. Fasten it on the wall or in it (depending on the type of execution) as well as a regular electric point.

At the end, it is necessary to check the performance of the already collected device again by connecting a laptop or a different gadget. Read also Article: → ".

Connecting RJ-45 wire for two twisted pairs

Preparatory actions in this case are produced exactly so that in the previous version. Difference can only be considered the connection itself. Instead of eight conductors, four existing in the wire are switched. The contacts corresponding to the colors of wiring and corresponding to the selected scheme "A" or "B" are activated. After that, crimped, assembly and installation of the product, checking the signal transmission.

Example of crossing the Internet wire with two twisted pairs in the RJ-45 outlet

Practical Tip: It should be remembered that the wire with two twisted pairs is used to transmit data at a speed of up to 1 GB / s. With an increase in the speed of the Internet signal, the wire will have to be replaced and all connections produced on it too.

Implementation of wiring on contacts sockets

As mentioned above. When connecting wiring to the terminals of the device, it is necessary to carry out them. This procedure will depend on the quality of the entire system. Do not think that you need to scrupulously remove the shell from each wiring, then put it on the bolted connection, as it happens in conventional electrical outlets. The system connections contacts are arranged so that with a dense institution on them, the conductor, they cut the insulating coating and ensure switching with copper residential. At the same time, it is not necessary to clean thin wiring.

Such a high-quality and reliable connection is achieved when the wire enters the contact terminal until it stops. You can use a knife or thin screwdriver for this. But it is necessary to act extremely careful not to damage the wire. Read also Article: → ".

Connector Connector for Connecting a Computer With Outlet: Step-by-step instructions

To connect a laptop with an Internet socket, you must have a power cord equipped at both ends with connectors - transition devices that provide connection to the RJ-45 jack. The crossing of the connector on a wire with four twisted pairs is made according to the color schemes proposed in Figure:

Color scheme for crossing the RJ-45 Connector for options "B" and "A"

The installation process of the device on the wire can be represented as a step-by-step instruction:

The wire at the end is released from the protective shell, after which the conductors of the twisted pairs are promoted and aligned
Wirings are distributed over the colors specified on the corresponding color scheme and cut down one length - 10-12 mm
Having plains tightly to each other, they all come together in the connector, after which the correctness of their location is checked again.
Using the crimping tool, the wires are crushed in the connector.

If the crimping tool is not available, the crimping can be made using a thin flat screwdriver. To do this, the screwdriver is alternately need to click on each of the contacts of the device so that it is to stop the conductor in it. At the same time, the built-in micronozh shifters the insulation of wiring and ensures reliable switching. Wire Crossing Scheme The Connector must match the scheme in the outletRJ.-45. Otherwise connecting to the worldwide network will not be available.

Other Connector Connection Schemes

In addition to switching a computer with an Internet connector, you may need a cord for connecting a computer with another computer. In this case, the crossing will differ at different parts of the wire. Also, do not forget about the 2-paired wire, which is also often used for connections.

Common Errors when installing computer connectors

The most common errors when installing sockets and connectors are associated with an inattentive attitude to the distribution of wires in color.

Error 1. A computer socket is installed independently according to the "B" option, and the connecting cord is purchased with the gadget or separately, but already assembled. The user without checking begins to connect. The error lies in the fact that the wire can be mounted according to the "A" scheme, in this case there will be no connection. Before use, you need to make sure that the connotor crossing is performed accordingly.

Error 2. User for security good contact Trying to clean the wiring couple with a knife. The error is that it is a waste of time and strength. The transmission of the signal from such procedures will not be better. Correct crimping will provide fast switching and reliable contact.

Error 3. Leaving too long free end of the wire when installing a socket. The error will be displayed only after connecting the wire, while mounting the device to the wall or inside the wall. If the cable length does not allow it to be in the opposition, the entire connection procedure will have to be repeated again, after it is shortened. Therefore, you should not leave a large piece of cord - 15-20 cm is enough.

Error 4. The use of poor-quality products of a dubious manufacturer. Installing the Internet socket refers to the questions that arise quite rarely. It is for this reason that it is not to save and jeopardize the use of resources. global Network. It is better to purchase a high-quality device of a well-known manufacturer. Also applies to cables.

Practical Tip: If the user has no idea about working with sockets and wires, it is better not to try to carry out installation and connection yourself. It is recommended to use the services of specialists who will all make competently and quickly.

In conclusion, I would like to note that the Internet is an outstanding achievement of modern civilization. Attitude to the possibility of accessing this resource should be responsible. Properly performed work on the installation of a computer socket and cord with connectors will provide high-quality and reliable communication with the World Information System.

Most often, the installation and connection of the Internet socket relating to low-current lines is made in the triple block:

Normal 220 volts

Internet socket

television

Most models, such as Schneider Electric (Unica series), Legrand, Lezard, the installation principle is almost the same and does not contain cardinal differences.

Step by step. Consider the entire cycle connecting the Internet socket.

Internet cable

Installation begins with installation in a low-current shield of the router and connecting it from a 220V power outlet.

Next, in a separate cable channel or a strobe that is not associated with the power lines, the 4-paired UTP series 5e is paired.

Such a cable provides a connection speed to 1 gigabit per second at a distance of up to 100m. Here it specifications:

There are shielded and not shielded varieties. Foil as a screen performs on networks where there is a normal grounding.

One such cable is 5e (4 pairs), you can connect only two outlets. In this case, 2 pairs will be involved separately.

Installation is carried out by a solid wire directly from the shield to the opposite. Create the cable to the mounting box and leave the necessary reserve - from 15 cm and more.

Montage online sockets

From the socket, you first remove the lining and pull out the caliper for the convenience of installation.

If the design of the socket allows, the frame on the peavern can be mounted initially. Thanks to the groove in the frame, you can easily adjust the horizontal location.

3 * 25mm screws pre-tighten the entire design. At the same time, the Pocket Electric level is checking the installation accuracy and tighten the screws finally.

Manufacturers have recently begun to perform frames made of aluminum alloy, they are certainly tightened by design, but they will not be magnetized to the level. We will have to keep it with one hand on weight.

Next, we biteate and leave the wire supply in the riser, a maximum length of 15 cm. Remove the top layer of isolation from the UTP cable.

For removal isolation, so as not to damage the veins, it is better to use a special tool - stripper. But you can do all this neatly and ordinary stationery knife.

The top layer from the cable must be cleaned for a length of no more than 2.5 cm. Cut off the thread unnecessary in this case, which goes between the veins.

A strong thread in cables with a twisted pair is often used to facilitate the opening of the shell on a long length. It is even so called - the discontinuous thread. In the telephone cables it is separated by bundles and oops.

Slightly depart separately alkali. Next, pull out the inside of the socket with contacts.

As a rule, to any brand, whether TV, the Internet socket or the usual 220 volts must go instructions.

Standards and Connection Scheme

Open the cover of the contact part and carefully study the label. Each RJ45 outlet can be connected in two ways:

According to the standard "A"

According to the standard "b"

In most cases, the second option is used - "B". To understand where what wires are connected, carefully inspect the case. It should be depicted which standard corresponds to certain contacts.

For example on Unica:

The protocol "B" refers to the upper color label. When connected, you will focus on these colors.

"A" - to the bottom color marking

If they figured out this, then with further installation there will be no difficulties. The "B" protocol corresponds to the color scheme according to EIA / TIA-568B standard. On one side of the clamp should be the following colors:

white orange

orange

white green

green

On the other side:

blue

white blue

white brown

brown

Move the wire through the lid. In this case, as mentioned above, the top layer of the UTP cable isolation should not be removed, more than 2.5 cm.

It is impossible to clean it under the very wall of the opposition, as they make with ordinary NYM or WGN cables.

Cut without insulation should be minimal length. All these oblasts are made not with simple. Their exact amount per 1 meter cable is strictly calculated and regulated.

Otherwise, incorrect connection And the stripping you can decrease not only the speed, but also the quality of data transfer.

Next, insert all the wires into contact grooves in colors.

After that, just snap the lid. Extra segments lived, which protrude out it is necessary to cut down after closing the lid.

The socket is actually already connected. It remains to insert it into place in the caliper.

The main advantage of such online sockets is that they do not need to remove insulation with them at all and slander it before copper. Inside the socket itself already installed special knives.

When you slam the cover, the knives automatically cut through the insulation and the contact compound is formed. In the instructions such stamps often indicate that when the wire is connected, the use of special crossover crimping is prohibited.

It seems to be in the design. That is, when the lid closes, it slices the insulation itself and lays the wires to the desired depth of the connector.

Connect to the router and connotor crimping

After mounting the Internet socket itself, it remains to correctly connect the cable to the router in the communication shield.

Remove isolation from the other end of the cable by 2-3cm. The veins are flushing and insert in a certain order, according to the TIA-568B standard, or simply "b".

The location of colors is considered to be left:

white orange

orange

white green

blue

white blue

green

white brown

brown

Standard "A" is sometimes used if you need to connect one computer with another. Here one end of the cable contract according to the "B" standard, and the other by "a". In general, if both ends of the cable are compressed according to one standard (AA or BB), it is called patch cord. And if they are changed in places (AB or BA), then - Cross.

Veins again do not need to clean. Just insert them into the connector until it stops.

After that, all this is pressed by a special crimper. Some make a thin screwdriver or blade a knife, though you can easily damage the connector.

Cat5E cable and Cat6 in the RJ45 connector are crimped according to one principle. Another "plug" is not required here. Differences in cables in data transfer rates, Cat6 is more.

Internet connection check

After installing the Internet socket and connector on the other end of the cable, it is desirable to check the connection and integrity of all connections. You can make it the cheapest Chinese device.

What is his essence? There is a signal generator that submits pulses by specific codes, and receiver. The generator is connected to the router installation site, and the receiver directly into the socket itself.

After the pulse is supplied, the signals are compared. If everything is fine, the green LED light bulbs on the receiver case are alternately. If somewhere a break or short circuit, then one or more light bulbs will not burn at all.

When this happened, first of all you need to sin on bad contact in the connectors. Most often, it is there, on any dwell, isolation is not completely cut off and there will be no compound accordingly.

At the very end, the finished proven cable with the connector connects to the router.

A complete set of all the tools for cutting, compresses, Internet Cable UTP cable can be ordered to Aliexpress (Free delivery).

How to connect 4-wire telephone cable

And what if you have a 4-wire telephone cable for the Internet, and the socket under the standard 8 lived? How to connect the scheme in this case?

A simple color connection here does not help. That is, if you have a white-blue inhibit in contact with white-blue marking and in the color of the coloring, connect all other veins, there will be no signal.

This is explained by the fact that to transmit the signal to use contacts 1-2-3-6.

On the one hand, two veins start 1-2:

green \u003d. bluelived

In this case, everything should work without problems. Just remember that here the most important thing is not color, namely position. Colors are used in order to be visually easier to distinguish between the positions of the same veins at different ends of the cable.

Also keep in mind that when using 4 wires, i.e. Two pairs of twisted pair, you can reach speeds up to 100 Mbps / sec. But for a gigabit network (1Gbit / s), all 8 wires will be needed.

Errors when connecting the Internet socket

1 Incorrect connection lived according to the protocol.

You can easily confuse the order of the location of the veins on the connector and in the rosette itself. Roughly speaking to flip them over 180 degrees.

Here, everything is checked by a more careful study of the inscriptions on the housing of the socket and the colors themselves lived. Tester with generator and signal receiver good assistant To identify such errors.

With incorrectly opening, lived, the light bulb on the tester will not light up in order from 1 to 8, but in arbitrary versions. For example, first 1, then at once 3, then 2, etc.

2 Not significant, but still the error is considered if the veins from the contact plates of the socket are not cut off after the cover is closed, and up to this point.

That is, immediately after laying them in their places in the slot. In this case, there could be accidentally falling, and inserting it back cut off will no longer succeed. We will have to re-inspire everything and pass the entire connection cycle on a new one.

And if you left the cable stock in the mounting box small, then you will come to the big headache at all.

3 Stripping external isolation on a large distance, up to the walls of the opposition, as in conventional networks 220V.

As mentioned earlier, here is the result - deterioration of the speed and quality of the signal. Moreover, you do not need twisted pairs to break up to the place of insulation, the more screwdriver. Just expand their lifting the veins on the required length to start in the slot.

According to the standard, no twisted pair is allowed on more than 13mmOtherwise, crosstalk errors will appear in the tests of frequency characteristics (Crosstalk). In practice, problems will begin when loading the network of traffic.

To connect a computer to the Internet, use a wire called twisted pair. To connect it, you need to pre-prepare the ends of the cable. More precisely - to put special connectors on them, which can already be connected to a computer or router.

Sometimes it is required to divide the wires of the Internet around the house or office. In this case, at the end of the twisted pair put special outlets. Within the framework of this article, methods for installing Internet sockets will be considered, as well as the basic rules for crimping the RJ-45 connector and connect the twisted pair.

The second name: Patch Cord. This is a small plastic transparent color connector, which is a "plug" session for network card jacks, routers, switches and other communication devices.

Depending on what the cable will be connected, two types of switching are distinguished:

Straight. To switch the computer's network card with a router / switch.
Cross. For switching two computers directly, as well as switches, routers or hubs.

To use a specific type of switching, the wire is crimped from both sides. The cable itself consists of several color veins, which are set in patch cord in a certain order. This order and determines the functional load of the cable.

Important: Usually the wire in the apartment has a provider company. In this case, it is not always possible to see how it will be cured in the switch box. If you decide to put the RJ-45 connector on your own, it is worth learn from those. Company support, as initially a cable in the junction box was inspired.

Internet cable connection circuit

So, the twisted pair consists of 8 live wires. Each vein is in isolation of a certain color. List all colors:

Brown.
Blue.
Green.
Orange.
Brown-white.
Blue-white.
Green and white.
Orange-white.

We now turn to the RJ-45 connector itself. The patch cord is also present 8 contacts (pins) to which the veins of the twisted pair are supplied. Depending on which sequence, the conductors are charged, the functionality of the wires changes. The order of installation lived in the connector is also called "pinout".

If you look at the connector from below so that the latch is watched in the floor, and copper contacts - per person, it turns out that contacts will be located in order from the 1st to the 8th right-left. It is important not to confuse the order!

Based on this, the color connection circuit is as follows:

Orange-white.
Orange.
Green and white.
Blue.
Blue-white.
Green.
Brown-white.
Brown.

Both ends of the connector are crimped according to this scheme.

Reverse (for cross-join). One end of the twisted pair is crimped as with a direct scheme. The second is connected in the following sequence:

Green and white.
Green.
Orange-white.
Brown-white.
Brown.
Orange.
Blue.
Blue-white.

To grind the wire, it is desirable to have a special tool at hand, as well as have minimal wire wiring skills.

Information: If there are many wires of twisted pair in the apartment or office, all of them are unlocked different ways, It is worth placing the wires with the feedback. This will facilitate work with cables in the future.

Crimp twisted pairs in the connector

To compress twisted pair, it will be necessary:

Two connectors RJ-45.
Special crimping scissors - Crimper.

Consider step by step algorithm Wire crimp:

One end of the twisted pair is cleaned of external insulation with the help of a crmper. To do this, it is inserted into the circular hole of the scissors, about 1-5 cm and remove the outer rubber layer of the wire. This action is similar to removing insulation from electrical wiring.
Brush and exhibit veins according to the switching scheme. Align the veins in length. It is important that each posting is one size. After that, gently insert the veins in 8 micro-ribs on the crmper and remove the isolation from them.
We insert the bare cores according to the color scheme in the patch cord. At the same time do not forget about the pinout of the connector. We once again check that every lived came into your contact. IMPORTANT To do not come to one PIN somewhat live!
Gently install the connector into the rectangular hole of the crmper and squeeze the handles of scissors.
Let's get the chenched wire.

This is the correct way of crimping cable. However, existing configuration methods for installing the connector.

How to clip twisted a couple without Crim

Not in every house there are crimp scissors. It's rather professional instrumentwhich does not find your device in everyday life. Most often, their crimper is at hand, so you have to work with what is in the house.

So, for home installation of the RJ-45 connector, we will need:

A sharp knife.
Little straight screwdriver.

The sequence of actions is exactly the same as when working with crimp scissors. Only removing all isolation from the wires will be made with a knife, and the clamp lived - with a screwdriver.

It is necessary to very gently pour each core in the connector. To do this, it is best to fix the patch cord in the vice, and the twisted pair to hold his free hand. The core clamp a copper tongue of Pina. It is fixed with a small screwdriver.

Check compound

It is worth checking all the patch cords for reliability. There are three main ways:

Connecting the finished wire to the network to test the performance. In this case, check the data transfer rate and the response of the network.
Check the wires on the break and combination. In this case, the connector is slightly rejected from the wire or sway from side to the side. Correctly fascinated twisted pair will not give patch-cords to hang out, the connector will not be very sad, and all the veins of the wire will remain in their places.
Check multimeter. One of the most reliable ways that can be used as the method of diagnosing the entire cable. The transclon of each veins of the same color from the two ends of the twisted pair will allow you to determine the rupture of the wire, as well as the quality of the signal transmission on it according to the resistance of the core.

The listed methods allow you to estimate the quality of switching to the full.

Having understood with crimping twisted pairs, we turn to the main topic of the article - connecting the socket to twisted pair.

Installation of Internet sockets

Outlet for twisted pair allows you to hide all unnecessary wires in the wall, and on its surface leave the output to the Internet in any room. The entire installation process can be divided into several stages:

Design and variation of switching units (sockets) around the apartment or office.
Summing up the Internet cable to sockets. Punching the shoes and socket connectors.
Cable gasket and setting outlets.

This order is suitable for installing outlets of different types. Consider in order different types of connections.

Wall socket

The outer socket is reminded on its form old telephone nodes. These are small plastic boxes with an input of the cable on one side and the socket for the wire on the other. Consider the installation algorithm for this node:

Installation of plastic steps with a terminal bar on the wall.
Enter twisted pair into the outlet. It is necessary to start a wire with a margin, about 10-15 cm, in case the primary connection will be incorrect.
Stripping lived twisted pairs.
Connection lived in the terminal box according to the color scheme. Usually in each rosette there are tips on switching lived in a terminal bar. It is necessary to gently distribute the veins in colors and omit each of them into the clamping hole. Please note, when you do this operation, it is not necessary to remove the isolation with lived. It cuts through the internal terminal mechanism. If you successfully install the wire you will hear a characteristic click.
After switching, it was possible to close the socket with a plastic casing.

Useful: if the click was not heard, you can install the core to the end with a small screwdriver. Gently lower the core until the bottom of the terminal base so that he gets on the copper contact.

Inner socket

Installation of the inner socket in the wall does not differ from the installation of a conventional electrical outlet. At the same time, the switching inside the device is identical to the connection lived in the wall node. The difference can only be in technical execution Terminum and internal clamping devices of individual manufacturers.

ATTENTION: To carefully disassemble the outlet and do not break anything, carefully read the user manual. It specifies the full assembly / disassembly algorithm.

Conclusion

Installation of outlet in the wall is a simple event. The main thing is not to confuse the color scheme and act neatly and without a rush. Do not start too short wires into the knot. Quality network connection Check before mounting the wall outlet.

Despite the rapid development of wireless communications, RJ-45 sockets still remain the required elements of the structured cable system of the modern building. We propose to consider their device, species, pickup options and mounting methods. The seeming simplicity of the question can be misleading because there are certain nuances that need to pay attention.

Constructive features

Despite the variety of types of sockets under the twisted pair, their design is almost identical, with the exception of small details. For example, we give a typical external single-port device.

Fig. 1. Basic elements of the external socket RJ-45

Designations:

A - plastic cover.
B basis.
C is a function card with a standard connector installed on it.
D - Convectors for connecting twisted pair.
E is the screed for fixing the cable.
F - connector under the connector.

Externally, the socket reminds the telephone standard RJ-11, the main difference is in the number of connector contacts, their eight, and not four. Accordingly, the computer socket can be used as a telephone, but not vice versa.

Different types of devices may have minor characteristic features, but in general the concept of the design remains unchanged.

Types and characteristics

The main parameters of these switching devices are determined by the following criteria:

Number of ports.
Category.
Execution.

Briefly tell about each of them.

No longer means better.

One of the main parameters is the number of ports. As a rule, there may be from one to four. If you want to use a larger number of connections, it is easier to install a patch panel, but such a need indicates an ill-mounted wiring of the network. In addition, it should be borne in mind that a large number of patch-cords connected nearby is some inconvenience.

Fig. 2. 4-port exterior socket Krauler.

In practice, when organizing an office or homemade LAN, one and two-two modules are mainly used.

This parameter is directly related to the cable characteristic used to install a computer network. We are talking about bandwidth, on which it depends on both the data transfer rate and the ability to use special network technologies. Below is a table that shows the relationship between the bandwidth.

Currently, when installing LAN, the cables with the category below 5e are practically not used.

Execution.

This parameter depends on the method of mounting the switching device. There are two versions:

for external (outer) installation (such sockets are shown in Figures 1 and 2);
under the internal installation.

Internal two-port rose rosette in disassembled and collected form

As a rule, the choice of one or another depends on how the LAN wiring is performed. If it is external (for example, laid in boxes), external sockets are applied. In cases where hidden wiring is made, internal devices look more aesthetically.

Separately, it is necessary to highlight the sockets that are installed directly on the box. Technically, such an execution can be considered both internal and external.

The performance of the LAN does not affect the technical characteristics.

Modular structures.

Speaking of performance, it is impossible not to mention modular structures. Such a solution allows you to assemble a socket under a specific combination in a standard case, for example, to install in RJ-45 and RJ-11 modules or with different categories.

Pickup RJ-45

There should be no problems with these problems, because in front of each contact group, the color marking corresponding to the T568A and T568B standards (may be marked with the lines "A" and "B", as in the figure below).

It does not matter which standard is used, the main thing is that it is the same type for LAN, otherwise the problems are guaranteed. It is believed that we have adopted "crimp" by T568B type, but it is quite a conditional statement.

If you do not know which standard uses your provider, you can install it on the pinout of the connector installed on the cable coming into the apartment.

Detailed Instructions for Connection

Let's start with the tool that you will need to seal the sockets under the twisted pair. Ideally, it is desirable to purchase a universal extractor (shown in Figure 9). It allows you to presses and cut off the wire residue with one movement. Thanks to Chinese manufacturers, such a universal tool costs about 3-4 dollars. The price of brand products can be 2-3 times more expensive.

Fig. 9. Universal extractor

This tool has a special mechanism that allows you to press the wire between two knives of the contact and crop it over (3 in Fig. 9). In addition, it is equipped with a flat screwdriver (2) and crochet (1), which allows you to remove the wire with incorrect sealing. The cost of the universal extractor is relatively small, and the benefit is quite tangible.

Universal pliers to remove insulation will be no less useful. They cost about the same as an extractor, can be seed cable Ø3.5-9 mm type UTP, STP, FTP. It is possible to adjust the depth of the cut.

It is undesirable to use a knife for removing the insulation, because in this case there is a high probability of damageing one of the veins of the twisted pair.

Having understood with the necessary tool, we turn to the algorithm for the sealing of a twisted pair into the switching device. We will proceed from the fact that the cable is already laid, the seat under the socket is prepared. Procedure Next:

Using universal mites, cut the layer of external insulation from the end of the wire. It is enough to overcome 4-5 centimeters. It is necessary to act neat so as not to damage the veins. If this happens, cut the damaged area, adjust the cut depth and repeat the operation.
After removing the insulation, roll out each of the steam. Please note that in their sweeping there is no need. Each contact of the site has special micro knives, cut insulation and providing reliable contact and fixing the wire.
Disassemble the outlet. To do this, remove the front panel. To do this, you will need to unscrew the locking screw or sweep the special latches (depends on the constructive design). If a modular socket is used, then modules must be removed from it.
Fix the cable on the module using a screed (E in Fig. 1) or another provided by the design method.
Insert the wires into the clamps, while you must stick to the color marking of the selected standard. Do not try deeply drown the veins, just fix them, attaching a slight force (and Fig. 11).
Using the extractor, we perform pressing (in Fig. 11).

On the this stage We will make a slight digression regarding the use of submitted means for pressing. Sometimes you can meet tips in which in the absence of required tool For pressing, it is recommended to use a stationery knife or a thin slotted screwdriver. This approach can be applied only in the most extreme case when access to the network is urgently needed, and there is no tool at hand. But in the future such a socket must necessarily press. Otherwise, the likelihood of loss of contact of the wire with the retainer after a while.

We also note that many branded producers to each outlet are attached a simple plastic extractor, which allows you to reliably close the wire, after which it will only remain gently trimmed its excess.

After pressing the module is installed in place. If the outlet is external, then its base is screwed to the prepared area, so that the tail of the cable is carried out on top, and the connector under the connector is below. When installing the inner socket, its base is installed in the prepared glass and fixed in it.
We screw the front panel, after which you check the performance. You can do this using a special tester, but it is easier to connect a computer and check for the presence of a network connection. If there are problems, first of all, check the correctness of the pinout, as practice shows, in 90% of cases the reason lies in this.

When using the shielded cable, you must install the appropriate outlet, which contains the screen connection. Otherwise, it turns into a large antenna, which will not slow down to reflect on the bandwidth, and, consequently, the data transfer rates. For the same reason, you should not use STP or FTP cable if ungrounded equipment is connected to it.

LAN technology based on twisted pair requires the use of holistic lines. Twist, spikes are unacceptable, it leads to serious losses. If nevertheless an need to increase a piece of cable, special connectors should be used for this purpose.

Fig. 12. Connectors for twisted pair

These devices are a box in which a board with two RJ-45 connectors are installed (and in Fig. 12), or clamps under a twisted pair, like the outlets (in Fig. 12).

It is not recommended for living conditions to use outlets with the number of ports of more than two. A large number of patch cords in one place will lead to the fact that they will be tangled. It is better to dissemble the outlet for some distance.

Build any modern structured cable system It is impossible without a socket. To install it, you can call a qualified wizard, but you can make this work and yourself. Internet connection cables have a low voltage, so work is safe and easy to execute.

RJ-45 standard socket performed, but has a different appearance Depending on the manufacturer. In the catalog of companies producing cable products and accessories to it, you can find a photo of RJ 45 sockets.

Types and application

The most popular combined computer socket. It adds an additionally a telephone connector that allows you to connect not only to the Internet, but also to a stationary phone. It can be represented in several embodiments - overhead or RJ-45 rosette for internal installation.

The latter will require the stroke of the walls, however, will retain the presentable appearance of the room. The RJ-45 invoice is widely applicable in offices and rooms where there are a large amount of wires and their outer gasket in boxes and minications is appropriate.

Sockets can be multiported or single. Two or more ports will allow you to connect more equipment, because the option is as relevant when creating jobs in office space, but usually use sockets from one of two modules, and for more use already a patch panel.

The socket consists of several parts: bases, plastic cover, boards with a standard view connector, connectors for connecting wires, screed for fixing the cable and directly connector connector.

It seems that the socket is similar to the similar RG-11, however, the connectors are intended for 8 contacts, and not by half a smaller amount, which allows it to use it as telephone.

The RJ-45 pinout is performed using a color marking that complies with T568A or T568B standards. It is worth considering that the standard must be the same for the entire locally computing network otherwise there may be problems in connection.

Instruction how to connect a socket

Connection diagram does not represent complexity. It is necessary to cut off isolation from the wires for 2-3 centimeters, promotion of 4 paired veins, and clean from isolation, manually, but better with a stripper so that the wire extending outside the outlet is necessarily covered with insulation, and the bare part was in the outlet .

If you open the outlet housing, you can see that all connectors are indicated by a specific color to facilitate the connection. To hold the wire in the latch, you must click on it with a knife or screwdriver.

Manufacturers of high-quality products are usually applied with an extractor with an extractor, which helps to clean and snatch the wires. This is very comfortable toolwhich can be purchased independently affordable price Chinese producers or brand twice as expensive.

Special tongs for removing isolation will be useful. Their price is identical to the extractor and when applied it is possible to adjust the depth of the suction. Such pliers will help to work with various types of twisted pairs: UTP, FTP, STP.

When the wires are fixed, you can fasten the front panel and check the performance of a special connector or immediately turn on the network into the outlet to make sure that the completed work is correct.

At the T568B standard, the next pinout: 1 - white-green; 2 - green; 3 - white-orange; 4 - blue; 5 - white-blue; 6 - orange; 7 - white-brown; 8 brown.

The T568A standard is used more often, placing: 1 - white-orange; 2 - orange; 3 - white-green; 4 - blue; 5 - white-blue; 6 - green; 7 - white-brown; 8 brown.

Thanks to color marking, perform cable crimping in the outlet with your own hands is very easy.

When using the shielded wire, it is necessary to use the appropriate outlet, otherwise it will work as an antenna, which will immediately affect bandwidth And as a consequence of the speed of the Internet.

Only grounded equipment must be connected to the STP and FTP cable;
It is necessary to use only one-piece slices of twisted pair, otherwise it will lead to significant losses. In case of acute need of twist, pieces are manufactured using connectors;
At home and in small offices, it will be appropriate to use a socket with one or two modules, a larger quantity can lead to confusion of wires. Rosettes better disseminate to the sides, leaving a certain distance between them;
In order for the shock in the wall with the inner laying to the outlet, there was less than or not at all, it is possible to pave a vita pair under the plinth;
If there are no special fixtures for the cable in the presence, then they can be made of themselves from tin wiring. This coma is possible to navigate the cable with small carnations or to fasten with self-draws every 30-50 cm.

Installation on the wall

As mentioned above, the fastening of the socket can be in several ways, after selecting the optimal number of ports for this room.

To hang a wall-type outlet, after establishing a cable in the connectors, it is necessary to attach its back wall with a dowel to the wall and put on the upper lid.

To establish an internal outlet, you will need more time. After the cable is chosen, you need to drill a hole in the wall under the outlet and fill it with a chisel and hammer.

The wall between the sockets is extruded. If a high speed internet is connected, then the stroke must be carried out also to the distribution box.

At the finished hole in the wall, peavernacle is inserted and closed with a solution of plaster. The cable on the stroke goes to the installation box, and from it to the outlet, which is securely fixed in the installation box with the help of self-tapping screws.

After the end of the listed works, it remains only to wear the upper part of the outlet. Despite the difficulty of installation, the hidden method allows you to save aesthetic room and avoid using boxes and mini channels on the walls.

This products can be purchased from foreign and domestic manufacturers. The best network sockets that differ in quality and durability manufactures such firms as "Legrand", "SchneiderElectric", "Vico", "R & M" and others.
