How to handle the disconnection of the headphone cable?

After the earphone is used for a long time, it is easy to cause problems such as disconnection of the earphone cable. The disconnection of the earphone generally occurs mostly after the earphone plug, the earphone split line, and the earphone unit outlet.

Don't worry if the headphone cable is broken. Here is a detailed introduction to how to connect the headphone cable:

Generally speaking, the red line is the right (R+) channel, the green line is the left (L+) channel, and the two yellow lines are the common ground line (G-), as long as the colors are one-to-one correspondingly welded together, the earplugs Red to the red of the main line, the green of the earplugs to the blue of the main line, the yellow of the earplugs to the yellow of the main line is ok

Regarding earphone users, especially the entry-level earphone products, the most common situation in the application process is that the earplugs "single side and not side", which is what we often say is poor contact. In fact, regarding this situation, we can completely repair it by ourselves, but suffer from the lack of corresponding tutorials, and ordinary netizens do not dare to take this risk.

Editor's Note: This operation is suitable for users who have a certain ability to start, and ensure that your earphones have a warranty period; if your earbuds are still under warranty, please contact customer service to repair them to prevent unnecessary losses.

Normal earplug plug

It is well known that earphones/earplugs are consumables. They often appear in various applications for several months. However, according to the investigation, the wire-breaking effect formed by the short-circuiting of the wire at the earphone plug is often caused by the short-circuit of the wire. More than eighty! Many friends' earphones use a few months to appear on the other side of the ring, and the other side can only buy new headphones to form an economic loss! Economic crisis, we have to be the "governor", now we will share the knowledge of entry-level headphones / earplugs:

Earplug plug complete

There is a sound in the root of a SONY headphone plug. As long as there is no sound, as an example, unplug the sleeve on the plug and find that the copper wire inside the rubber plug has been broken because the root of the plug is often broken. Some tensile and anti-ballistic wires are still connected (breaking the bones and connecting the ribs). The anti-stretching anti-ballistic wire is non-conductor!

The copper wire inside the rubber was once disconnected

In fact, the more the ballistic wire and the copper wire contained in the earphone cord, the stronger and more normal. Assume that it is often folded and folded (not necessarily intentionally folded, it is the bad habit of using headphones in peacetime, unintentional!) will form damage!

Cut from the broken end

Use scissors to carefully cut the plastic at the root of the plug to reveal the solder joints!

Exposing solder joints

Reveal four wires

Pull the other end of the earphone cord away and reveal four wires (enamel wire)! The red line is the right (R+) channel, the green line is the left (L+) channel, and the two yellow lines are the common ground line (G-).

Plating solder is also an important part of the game, which is more difficult for novices! The power of tinning soldering iron on the enameled wire must be larger, and it is done with flux such as rosin or solder paste!

Plating solder

Carefully solder the tin-plated wire to the plug, it must not be "short-circuited" solder joints are small, the solder should be excessive! The welding time can not be long. The solder joint between the solder joint and the solder joint is separated by plastic. It is easy to "short-circuit" when the welding time is long! The picture above is green (L), red (R), yellow (G), and all 3.5mm flat sound plugs are defined as follows!

The position of the solder joint is beautiful

Wrap the soldered plug in hot melt!

Wrapped with hot melt

Then bake the wrapped hot sol with a lighter and instantly put the sleeve on the front of the socket! Speed ​​and time should work well together.

Tip: Your hand should never be stuck by the hot melt that just melted.

Put the sleeve on the front of the socket

Wait a minute! After the glue is cooled, remove the excess hot melt adhesive! Basically formed!
