Can the cord at the earphone plug be torn and connected?

How to deal with the disconnection of the earphone cable and the cracking of the earphone cable:

Headphone disconnection generally occurs after the earphone plug, earphone splitting and headphone unit outlet.

At the headphone plug, when the headset is in poor contact. There is a reaction at the moving plug, indicating that the wire is broken here. Cut the headphone cord from here. Then peel off the thread to find the broken part of the thread, and cut the core of the thread neatly. There are a total of 4 lines, which are the left channel, the left channel, and the right.

The vocal and right vocal channels are distinguished by color.

For the plug is three-pole, the left and right channels are connected together, and the earphone cable is covered with insulating paint, so it cannot be measured directly by meter measurement, and the wire head should be plated with tin first.

The specific operation method is to first coat the rosin or solder paste, and then use a soldering iron dipped in tin to iron until the solder soaks the thread. Then it is best to disassemble the earphone case and use the watch to measure the four wires and check the other broken wires. If it is normal, it means that there is only this one broken line.

Then peel off the soft sleeve on the outside of the earphone head, and cut the hard plastic behind the plug with a blade to expose the solder joints. Then solder the wire up. Generally, the two ground wires are welded in the thickest part, the right channel is welded in the middle, and the left channel is welded in the thinnest part.

Generally, the two yellow lines are the ground wire, the red line is the right channel, and the green line is the left channel. Of course, there are exceptions, and it is better to take the unit apart and measure it. Check it after soldering to prevent short circuits.

Turn off the computer first, clamp it with tweezers or scissors (pliers) and pull it out.

1.Cut off the outermost black rubber layer and leak out the metal wire inside. Straighten out each thread and don't mix. There are white plastic fibers on the inside of each thread, which are picked out and cut off.

2.Use a lighter to burn off the insulation on the outside of the copper wire. Note: The burning time should not be too long, so as not to burn the copper wire, as long as it is on the flame a few times.

3.After burning, the ashes of the insulation layer remain on the wire, which can be scraped off with scissors and other items to ensure that it can be turned on after connection.

4.Connect the corresponding threads. If you can't tell which one is right or plug in the headphones, try to see how they can work properly. Combining the two judgment methods can be accurately distinguished.

5.Once attached, wrap the ends of the wires with scotch tape or other insulation. This is done first of all to avoid mutual conduction short circuits, and in addition, it also plays a fixed role.

6.The connection can be placed in a small adjustment box, which not only protects the stability of the connection, but also keeps the headphones looking good after repair.

1. Winding. In order to ensure that the audio signal can be transmitted effectively, in addition to the outer plastic layer and anti-interference layer, the earphone cable will also have an insulating layer on the surface of the internal copper wire.

If the earphone cable is broken and you want to reconnect it, you can use a lighter to bake the copper wire on the inside, remove the paint on the outside, and then use the winding method to reconnect the wire.

2. Welding. If conditions permit, the best way to reconnect the earphone cable without removing the original earphone cable is to use a welding torch and solder to connect the broken earphone cable.

Although it is possible to use the winding and burning method, the interface is not seamless, and the more connectors, the more unstable the audio signal transmitted by the earphones.

Therefore, if you want to restore the headphones to their original shape as much as possible, the safest way is to use a soldering torch and solder to solder the copper wires of the headphones for exercise.

3. Line change. This method is the best way to solve the fracture of the earphone cable, no matter what kind of earphone, it is generally divided into the earpiece, the line, the volume controller, the plug is composed of these parts, and the earpiece, the volume controller, the plug will have a "soldering point", if you understand this knowledge, and will use a solder gun, you can directly melt all the lines of the earphone, and then use a new earphone cable to re-melt it.
