Computer socket and its species

To connect the computer equipment and any other peripheral devices used computer network port RJ-45 standard. It corresponds to common norms and standards of communication designed to automate most of the tasks.

The device includes a plastic housing within which is placed between one and four slots.

communication system element

Computer socket is a device whose main function - a compound transmission from the network card of the computer to the cable network

For a home network often use devices equipped with one or two sockets. In devices with two first connectors for connection to a computer running an information cable and the second - to connect a panel punch.

Transmitting information cable, referred to as "twisted pair"Simply is put in contact with the module dedicated to him. Through another twisted pair information leaves the network.

Differences between RJ11 and RJ45

Telephone RJ11 standard modules include a two-pair connectors with four contacts, and telecommunication devices are equipped with RJ45 type 8th contacts

Externally computer RJ45 connector similar to an analog telephone RJ11. But the main difference between the device - the number of contacts. The phone models of 4 contacts, and information - 8 pieces. For this reason, if the computer RJ45 socket you can use as a phone, you will not be able to connect the computer equipment to the RJ11 connector.

The sequence of the installation of most types of computer sockets typical. Perform the desired number of almost similar steps:

Categories of information outlets

On which category belongs to Computer socket, dependent distance at which the signal is transmitted with minimum distortion, as well as the very data rate.

When equipped with the office and home networks often use these types of sockets:

  • RJ-45 Cat.5 - designed to organize 100BASE-TX network with a bandwidth of 125 MHz at a data rate in the range of 100 Mbit / s.
  • RJ-45 Cat.5e - more "advanced" option, allowing you to transfer data to two pairs within the 100 Mbit / s, four pairs -. 1000 Mb / s.
  • RJ-45 Cat.6 - are intended for arrangement of networks "Gigabit Ethernet" and "Fast Ethernet". The capacity of the unit up to 1000Mbps / second.

Identify several basic parameters, which are separated by computer outlet. One of them - the installation method.

External and internal connection points

Depending on the method of mounting devices are divided into two types:

  • external - used when a device should be placed on the wall surface. On the back side of the device for surface mounting connector is equipped with blade terminals. If they push the wire, insulation breaks the veins, thereby greatly facilitates installation.
  • internal - involve installation inside the mounting sleeve device recessed into the cavity of the concrete, brick or plasterboard wall. Connector such devices usually removable. It is removed, and after the installation of an in-depth into the wall podrozetnik plastic clamp screw.

Housings devices for outdoor use is made of a strong non-combustion type technopolymers. Due to this their outer surface is resistant to UV rays.

Inner lining system

Application of domestic outlets provide a presentable appearance view of the wiring, but complicates the servicing process in case of damage

Complete and collapsible model

Depending on the type of configuration devices are divided into two types:

  • With built-in modules. In models equipped originally with the contact board and connectors. They provided a constant type of screening.
  • With interchangeable modules. In devices of this type of modules separated from the front panel. Such a solution allows to make any combination: «UTP» and «FTP» different categories - 3, 5, 6, 7.

Complete device with built-in modules are available in cost and easy to install. But in case of damage it is necessary to replace the entire structure.

The device with a removable module

Devices with removable module benefit is that they are easy to maintain and flexible module, if necessary, will not be replaced in accordance with the needs of the system

The main criteria that should guide the choice of devices - availability of additional ports. For example, when service need several pieces of equipment, it is necessary to select dual socket type RJ-45. The two-module model to one RJ-45 port can be connected to a computer, and to the second RJ-11 - telephone.

There are also models in which both modules are used to connect computer equipment. But ports differ by category and type of screening. The use of these devices allows you to save paper costs by combining the modules to fit your needs, and equipment category.

Give preference to products trusted manufacturers. This ensures that products are manufactured in accordance with the generally accepted norms and standards. Quality devices will easily be combined with any type of computer hardware and safely withstand a Russian networks.

Requirements set of devices

Without a set of components can not be made Computer connection outlet.

will have to be purchased separately:

  1. Cable (lan) the appropriate category.
  2. The connector (jack) - the adaptation of Eight-plug for connecting the cable to the port on your computer.
  3. Patch panel - Provides the ability to quickly switch between the active network equipment and operating points. The number of devices depends on the number of ports connected equipment and can vary from 10 to 50.

RJ45 socket for connecting cat.5e need chetyrehparny shielded cable "twisted pair", equipped with a common screen types foiled KVPEf 5e 4h2h0,52. In the case of connection RJ45 cat.6 models also require four pair "twisted pair", but the type KVP 6 4h2h0,57.

A common variant of cutting

Conventional option of cutting in Russia is considered to EIA-5688 standard; its marking symbols displayed the Latin letter "B"

Vosmizhilny cable Internet consists of four twisted pairs. The second account in each twisted wire pair has a white insulation and labeled white stripe.

Data cables are divided into several categories, starting with the third. The higher the category, the higher the transmission standard.

To transmit data to 1GB / s-pair cables are used, and in the range of 10 Gb / s - chetyrehparnye analogs. The difference in price is not high. Therefore, planning to engage in further increasing the number of conductors, it is better to acquire chetyrehparnuyu network directly.

Table categories Cables

Cables "3" and "5" category employ for data transmission at a speed of 100 Mbit / s, and categories, starting with the "5e" and higher -. 1000 Mbit / second

When installing connection points preference is given to a shielded cable types that are most protected from interference. Shielded cables suitable for a wide range of applications: telephony, smart TV, Ethernet.

In the case of the installation cable is not long enough, or one of its parts is damaged, you can use an adapter "jack socket". When connecting the connector to build the cable to avoid errors, we just need to focus on applied inside the box color pointers.

Adapter RJ45 «socket-socket"

Adapter RJ45 «socket-socket" allows you to quickly connect the twisted-pair cables equipped with connectors of a standard, without compromising signal loss

When choosing a pat-panel, guided by outlet category. On sale there are "5" device category "5e" and "6".

The end of the data cable connector fitted with 8P8C, referred to as in the jargon as "Jack." It has a transparent body, which is visible through the colored wires.

This element is often mistakenly referred to as RJ45. But in fact, RJ45 - is the adopted standard, and the exact name of the connector 8P8C. Today, for a connection with the conventional equipment used since 2001 standard twisted pair lived TIA / EIA-568-B.

When you connect the Internet cable may be used two schemes: T568A and T568V. But in our country the wires have a generally employing the scheme of "B".

Standard connection "B"

Standard connection "twisted pair" lived TIA / EIA-568-B includes a sequence of lived in this order: (1-2) -White-orange with orange (3-4) - white and green with blue, (5-6) white-blue with green (7-8) - white and brown with brown

When connecting networks 10BASE-T and 100BASE-T using standard TIA / EIA-568-A. Fear that by chance something can be confused, it is not necessary when connecting the twisted pair. Current models of routers are designed for both. Therefore, they are able to automatically flip signal.

location of points of connection rules

If you are not a fan of "strings" of interwoven wires, it is worth to get serious about the placement of sockets. After each manipulation of the installation and transfer of the connection points means at least redecorating the room.

Connecting the desktop computer requires activation of at least five outlets. Therefore, the best solution is to install the unit, which includes several points: the modem, monitor, system unit ...

The female connecting unit

When choosing a location for the installation of information outlets should not focus primarily on the "European standard" - 15 cm above the floor level, and the number of plug-in technology

In fairness it should be noted that also allows the connection of computer equipment without operating outlets. But this method of installation is too complex to implement. And besides, it is not justified, especially in situations when it is necessary to work with large networks.

In addition, no one can guarantee with confidence that in the near future from this connection point will not be "powered up" another smart TV, computer or any other device.

If you want to increase the twisted pair, detailed instructions for connecting segments of Internet cable I set out here.

computer sockets mount technology

It is to connect a computer outlet with your hands, there is nothing difficult. We just need to adhere to in their actions specified sequence.

Selection of the necessary tools

To carry out the work necessary to prepare:

  • puncher fitted with a crown of appropriate diameter;
  • Cross-Connect for stripping knife;
  • Screwdriver Set;
  • tester.

In addition to the core set of tools necessary to take care in advance of purchasing crimping pliers. This tool costs about $ 10. And because for a single operation it makes sense to take it on rent.

Summing up the cable and installation Escutcheon

The first step is fed to the point of cable installation. It can pave the way open or closed. The first method involves laying a cable in plastic boxes equipped with removable lids, or occupancy per skirting walls.

overhead cable laying method

Placing overhead cable way and the "placing" of its DIN-rail mounting, it is possible not only to simplify the installation process, but also facilitate the maintenance process

Widespread and so-called modulnakladnoy method involving fixing the cable to the wall using special anchors option "quick installation".

To implement the second method of doing a Stroebe, in which the cavity and lay the cable. To do this, use the gun equipped with a special crown, doing a round niche in the wall. The diameter of the crown should match the size of the box.

Deepening the mounting sleeve

Mounting box connection point to bury make a hole in the wall and is fixed with screws and dowels

Let down the end of the cable is cut, leaving a margin for the possibility of subsequent multiple connections. An extra end to gently put a circle inside the box, avoiding fractures of the conductor.

Connect your device contacts

To connect the outlet via jumper knife blade outer protective insulation removed, freeing the end of a length of 5-6 cm. This procedure should be carried out carefully in order to avoid damage to the insulation.

Four different colored wire pair

Under stripped must show four pairs of colored wires twisted in pairs; In some cables is also provided a thin shielding wire

Each pair of gently leveled. We clean them is not necessary because the device itself is platform provides a reliable contact. With the housing socket remove the front panel by unscrewing the fixing bolt it.

Some models are equipped with special sockets latches that work clamp type. In such models, to take some of the hardware and gain access to the internal mechanism, you need to gently turn located on the rear face of the lock-lever.

Inserting lived in slots

Each core put in the slit outlet, focusing on the connection scheme with colors under each number applied to the upper bound of the device or in the attached instructions to him

All core alternately in accordance with the coloring is inserted into the lock. The end of each core is fixed with clamping bolts. To drown each core as far as possible, use the reverse side of knife stationery.

Color coding marking of the terminals greatly simplifies the process of interfacing a computer outlet and crimp twisted pair. Do not worry if you do not live comes through. When returning to the initial position detent recesses disposed laterally pulled across conductors through.

When all conductors are brought into the seats, sticking pieces of neatly trimmed.

All of the manner in which pinouts wire twisted pair, you can read here.

Set up a connection "core"

"Core" of the connected conductors is set into place by turning the lock-knob in the opposite direction

Applying the method outdoor installation, the device is fixed on the wall, directing the computer connector downwards and an inlet for the cable upwards. In the closed method of mounting a deepened outlet prepared for her nest fixing by spacers.

At the final stage with a tester check the connection. If the tester is not at hand, you can be connected, but not yet installed in podrozetnik "Core" just plug the end going to the computer cable.

Be sure to connect, we can only fasten the front panel.

Sealing plug for connector

To connect the connector to the end of the cable insulation is removed. Each pair untwist and level, pointing in different directions. If the provided shielding thin wire it for a while and folded to the side.

are oriented in a specific sequence diagram for the "B" described above vykladyvanii pairs.

Sealing plug for connector

Densely laid wires in one row are aligned and cut, leaving a length of 10-12 mm so that the insulation twisted pair began above the latch

Twisted pairs with cut off ends of wires led into the cavity of the connector. Wherein the connector latch must be placed down. Each conductor is placed on a separate track, trying to push it until it stops.

Connector with wires laid in it is inserted into the clamp. To seal the connection, you need to gradually reduce the handle mites together.

Using crimping pliers

The projections available in the landing nest mites, with pressure pushed the conductors to microblade, and those already erupted protective cover and ensure reliable contact

Ideally, if the connector housing "planted" into the slot properly, do not make any effort necessary. If necessary, the cable perezadelki only need to re-cut the end and follow the same steps, but with a different "Jack".

installation technology is similar to the double sockets. The only thing - from the router will have to bring the two cables as a parallel connection is used to network equipment.
