Modern man is surrounded by a variety of wires. Through the wires electrical current is passed and the information in the form of electromagnetic waves. For easy connection to a variety of devices designed connectors. One of the connectors is RJ-11, which are commonly used to connect telephones.
The question “How to fix the spring in the stapler” – 1 answer You need
- Crimping tool for connectors RJ-11.
Manual 1 For routing telephone communications inside are various wires. The most common, especially in older homes, received a telephone distribution cable (TRP), or “noodles”. Low reliability and noise immunity of the wire kompensiruet its low price, which explains its widespread use. More modern and convenient is the cord phone flat linear (STPL). Each of the four conductors insulated with individually colored plastic, which facilitates the wiring. All the cables sealed in plastic wrap, which eliminates mechanical damage. When you purchase a new wire should be preferred STPL or its analogs. 2 regardless of the number of conductors in the cord, for ordinary telephony uses only two. The rest can be used to activate phones in a “Director-Secretary” or a digital PBX. If you wire more than two wires and you do not know what is connected to the PBX, use the multimeter. You can also use traditional method of check signal “on language”, however it is unsafe. At the time the call voltage of the telephone line can reach 150 volts, which is enough for serious injury. If the connectors are on both ends of the wires, use color-coded conductors. All phone numbers, unless specified in the operating instructions, are used as working two the center conductor. The rest of the pins in the connector are not used. 3 to compress a telephone wire, you need to start exactly cut it, and then remove the outer plastic insulation at a distance of fifteen centimeters from the edge. As a result, you have to be the end of the wire sticking colored conductors. Do not remove the plastic insulation from individual conductors. Identify the two wires that are connected to the PBX. Place the conductors in one plane so that the connected wire is in the middle. Get the wires into the connector without disturbing the location. To stop crush wire into the connector. Enter the connector in the crimping tool. Ensure that the wires do not fall out of the connector. Firmly squeeze the handles ticks. Extract the compressed telephone wire and test it. A useful tip Connectors for crimping telephone wires are disposable, so it is better to have a few extra in stock. Tip 2: How to crimp the wire If you need to establish a local connection between computers, use one of the most common communication cables – twisted pair. When you do not have the cable, and the case urgent, and besides, his purchase will take considerable time – try to make this cable at home. This procedure, the technical process is simple. But will require additional knowledge in this matter.
You will need
- Tool kit for crimping cable
Instruction 1 to compress twisted pair cable (to connect twisted pair cable with a plug), you’ll need:
– a device for Stripping (stripper);
– pliers for crimping (like, ploskogorie);
– standard cable tester;
– wire twisted pair;
– plug standard RJ-45.
2 a Device for Stripping incise the outer shell of the cable “twisted pair”. Incision should be at a distance of 3 cm from the edge.
3 Incised the insulation must be removed. Rasplatita pairs and distribute them according to the colors that are listed on one of the schemas attached drawing.
4 and Then align the guides. Tightly squeeze conductors. Using a knife, remove the excess part of the conductors, leaving the unwound about 1 cm.
5 After alignment of the conductors attach the plug to them in the following way: the sections of the conductors should reach the end of the furrows. The cable jacket must bring the locking latch, bring the cord all the way.
6 check Again the order of laying of conductors by colors. After checking, place the plug into the crimping tool until it stops. Then squeeze both handles of the crimp tool. You need to compress the fork until it locks into place (you will hear a distinctive sound). The most important is the control blade, which is pressed against the knives. Ensure that they are not shifted past the contacts, because this will lead to the complete misalignment of the plug.
7 unplug the crimped cable and visually look at the quality of the connection: if everything is in order, it is possible to start manufacturing of the patch cord.
8 Patch cord is the cable “twisted pair”, which swage wire is made with two sides. For its production need to do the same thing you did earlier, but at the other end of the cable “twisted pair”.

The connection was reliable, you need to know the basics of soldering and have basic skills with a soldering iron. Even if you have never had experience of such work, do not despair – the skill comes with experience.
You will need
- Soldering iron, solder, resin, a nail file, a wooden plaque, alcohol
Instruction 1 Prepare the necessary tools for soldering wires. You will need soldering iron 40 to 60 watts, designed for a voltage of 200 V. Also stock up on solder and rosin. The solder is desirable to have tin-lead (POS 61). For connection of wires by soldering in hard to reach places use liquid rosin. To do this, grind a piece of rosin and pour a solution of alcohol, and then stir until dissolved. The room in which you are working should be well ventilated. 2 Prepare the soldering iron to work. To do this, sharpen it with a file tip and saladita. Sting stripped down into resin, then RUB the solder and the soldering tip on a wooden plank. The tip of the soldering iron will become covered with a thin layer of molten solder, whereupon the tool is ready to work. 3 Remove the insulation from the wireto be soldering. This can be done with a knife; it should act carefully so as not to damage the core wires. If the wire is stranded, twist the stem and saladita, putting on rosin and heating them with a soldering iron. The solder will spread evenly over the surface of the wire. 4 Soldering wire you can, put them on top of each other or making pre-twist. Twisted wire handle with soldering iron, pre-lowering the tip in rosin and solder. The connection is ready. 5 Check the soldering. High-quality soldering firmly connect wires, the ends of which have a smooth and shiny surface. If the soldering has a spherical shape, heat it with a soldering iron to melt the solder and remove the excess. When excess solder remain on the tip of the iron. 6 If the connection wire has a matte surface and appears scratched, talking about “cold soldering”. In this case, heat soldering, the solder melted, then let it cool without moving the connected wire.
