To teach you how to connect the broken wire.

"The bought twisted pair is just one or two meters, what can I do?" Believe that this scene is a lot of Internet users to form a home network often encountered problems. Twisted-pair length if not enough can only be bought again, and can not be as long as connecting the power cord extension, because a twisted pair is not allowed to have connectors, this is a little knowledge of the network of people know the truth. The reason why twisted pair can't have joint is that it affects the quality of network transmission. In practical applications, twisted pair will often encounter broken, cracked, not long, and so on, at this time, users can only re-laying twisted-pair line. In fact, broken and cracked twisted pair can also be repaired. Below, the author introduces you to the specific repair method.

A simple and practical method for repairing twisted-pair wires

For broken and cracked twisted pair, the simplest method of repair is similar to the connection of power cord and indoor telephone line, which is the lowest cost and the simplest and practical method of twisted-pair-line repair. "Soil-type" twisted-pair wire connection, only applicable to the double stranded wire distance of not more than 70 meters, if the twisted pair is too long, you can use another twisted-pair repair method, the author will be described in detail below.

First, repair tools

The repair tool is naturally very simple due to the use of the most Earth method to repair twisted-pair wires. A mesh clamp, a roll of waterproof tape, a knife.

The traditional connection method of power cord

Description: Because the twisted wire is composed of eight different colors of copper wire, although twisted pair transmission is weak, the same need for good insulation, it is best to have a certain degree of interference resistance. Because of this, choose to wrap the adhesive tape, do not use the traditional black insulation tape, but the choice of waterproof adhesive tape.

Ii. Methods of Repair

Although this method of repair is the most soil method, because of the particularity of twisted-pair, in the repair, we must pay particular attention to, and have a certain skill to say, do not feel free to get a joint, because this will affect the network transmission of twisted-pair cable quality.

1. Peel off twisted-pair wires

Use the clamp to break the twisted pair, then peel off the ends separately. In the actual network transmission, only the use of twisted pair of four lines, can be eight lines to one by one. Peel the twisted pair, both ends of the core copper wire length of 7cm is enough, if too long, the effect is not good.

2. Peel Copper wire

This layer also needs to be peeled off because of a layer of plastic wrapped outside the copper wire inside the twisted-pair core. Many users often use matches or other sources of fire to burn the plastic out of the copper wire, which is not possible. Be sure to peel the copper wire inside the twisted pair with a knife, because the ignition may burn the copper wire.

3. Connecting copper wire

After stripping the copper wire at the ends of the twisted pair, the copper wires at both ends of the twisted pair are reconnected. When connecting, be sure to follow the standard line sequence to connect, both ends of the line order should be consistent. In the copper line, must be connected to the connection, and do not jump line to connect.

Joints, must not be arbitrarily screwed on, but to use as shown in figure three winding method. Joints do not make a big knot, because there is a pimple, bad tape, the transmission quality is not very good.

4. Tape insulation

In the twisted pair of core copper wire insulation, each pair of lines must be insulated, do not wait for all the good after the bandage. Wrap the tape, do not wrap too thick, generally around two laps on it. Four pairs of copper core line after all, each line in accordance with the original winding order a little bit, repair work is done.

Third, line detection

After the twisted pair is connected, a simple test is carried out to determine the network transmission quality of the wire. Enter a DOS prompt window, run ping command, if the delay is less than 10 seconds to prove the good transmission quality of twisted pair. Conversely, it is proved that the repair is not qualified, you can cut off the above steps to repair twisted pair.

It seems to have become a "truth" that the twisted strand cannot be repaired after it has broken. In practical application, the user should dare to try boldly, after all, the theory is only theory, the fact is used for eloquence. The use of the power line to repair the broken twisted pair, no additional tools, the average home users have, this is a twisted pair of the most simple and practical repair method. The author has repaired dozens of twisted pair wires, the actual transmission delay is not much than 10ms, the transmission quality is quite considerable.

A method for repairing twisted-pair wires with the best transmission quality

In addition to the traditional "soil-type" twisted-pair repair method, there is a more scientific method of twisted-pair repair, although the process of this method is slightly more complicated, it can guarantee the transmission quality of twisted-pair wires. After the author's test, the repair of twisted-pair, and the complete twisted pair, there is no significant gap between the use of ping-command test with the complete twisted pair of twisted wire almost no difference. Below, the author details This kind of repair method.

First, repair tools

Actually, this repair method is based on the telecommunications department to repair the communication cable and improved, because the communication cable and twisted-pair cable has too much similarity, coupled with the telecommunications industry for cable repair quality requirements are relatively high, the use of this method can fully meet the home network users of the twisted pair of communication quality requirements. Because this kind of repair method request is relatively high, the tool which uses naturally is relatively specialized.

This "professional" twisted-pair repair method, need to use the tools are: Nets pliers, knives, electric iron, solder, plastic pipe (can be twisted pair smoothly into the plastic tube), syringes, small files and professional waterproof adhesive.

Ii. Methods of Repair

From the tools listed above, this kind of "professional" twisted-pair repair process is still quite complicated. Below, the author describes the repair steps in detail.

1. Peel off twisted-pair wires

Like the "Earth-type" twisted-pair repair method, to repair twisted pair, the first thing to do is to peel off the twisted pair. In the stripping of twisted pair, must pay attention to, do not peel too long, because this kind of repair method, is directly with soldering iron. The length of the Twisted strand is 5cm.

Twisted Strand copper wire

As the twisted-pair wire in the four pairs of wires are winding, in order to maintain the original twisted-pair shape is not too bloated, we suggest that each pair of twisted-length has a certain difference, because in the welding twisted-pair, there will be a certain length error.

2. Peel Copper wire

After peeling off a plastic sheath outside the twisted pair, the plastic protective layer of the twisted-pair core copper cable is removed. Peel the copper wire protection cover, do not need to be too long, only need 3cm on it. Do not use matches or other sources of fire to burn twisted strands of copper wire, because this can not control the length of the more easily burned copper line.

3. Connecting copper wire

After stripping out the plastic protective layer outside the copper line, the next step is to reconnect the copper wires at both ends of the twisted strand. Before soldering with soldering iron, a plastic coat is set on the outside of the copper line at one end of the twisted pair of wires. The length of the plastic coat should be moderate, not too short, at least to be able to completely cover the copper line.

Connecting copper wire

In the welding, the twisted pair of copper lines in accordance with the line sequence as shown in the method butt together, with soldering iron point on the solder, with a soldering irons to weld the copper wire together. When welding, try not to appear big knots. After welding is complete, check to see if the weld is solid, and if it is not firm, it must be soldered.

4, finishing copper wire welding point

Because the copper line outside to cover a plastic protective cover, rather than winding insulation tape, therefore, the copper wire solder joints must be repaired. With a small setback will weld left over the solder point, so that it can smoothly put on plastic protective sleeve on it. Because the copper wire in twisted pair is welded, its diameter will increase, so, when dressing, do not just trim and ignore the firmness of the welding.

The twisted pair of four pairs of copper wire all connected to repair, do not rush to put on the plastic protection cover, but to repair the twisted pair of twisted wire to carry out a simple transmission test to test the connection of the twisted pair to meet the requirements.

Third, line detection

After the completion of welding finishing of four pairs of copper wires, the network transmission quality of the repaired twisted pair must be detected before the next work can be carried out. In the test, you can first put the copper wire outside the plastic protection condom, to prevent the copper line between the short circuit. To repair twisted pair of twisted line to test, use ping command to do a simple check on it, Yi Yanxiao 5ms is OK. If the time delay is not standard, the twisted pair must be repaired again.

Four, the package twisted-pair Line

After the line is tested, the twisted pair can be encapsulated. The protective sleeve outside the copper line is placed in the central position of the welding point, and then the professional waterproof adhesive is injected into the gap of the protective sleeve outside the copper line with a syringe. After all four pairs of twisted pair are packaged, the outer layer is sealed with an insulating blanket.

In this way, very professional twisted-pair repair on the completion of the calculation, the cost is no more than a few yuan, than the replacement of a new twisted pair of cable is much cheaper.

Conclusion:

In contrast, the "soil-type" twisted-pair repair method is more suitable for home network users, because the twisted-pair repair method is not only simple, but also very convenient. "Professional" twisted-pair repair methods to use some such as professional waterproof adhesive materials, one is not easy to buy, the second is the operation of a more complex process.

In the face of double stranded wire fracture can not repair the speech, users do not easily believe that the need to break the conventional courage to try, with facts to prove that the right and wrong, the fact that the twisted pair is also a way to repair.
