1. Prepare welding tools, plug in soldering iron and preheat.

2. Cut the earphone from the bad place.

3. Strip the place to be welded. The core wire is enameled, so it is best to scrape it with a knife or burn it with a lighter to remove a little insulating paint and then touch it with a little flux.

4. Prepare a heat shrinkable tube and put it on the thread end.

5. When the cable head is covered, peel off the skin on the earphone plug.

6. After arranging the lines on both sides, weld them back one by one according to the color.

7. Put the heat-shrinkable tube in the welding position, and bake the heat-shrinkable tube slightly with the flame of a lighter, and the heat-shrinkable tube will be firmly shaped.

How to connect headphones when the headphone cable is broken?

1, unskilled, line to line, left channel to left channel, right channel to right channel, ground to ground.

2. The earphone cable has at least three wires, and the coatings of three colors are all insulated. Wires of the same color are hung with blades to expose the metallic color of copper wires and then welded together, or directly screwed on.

3, pay attention to the three wires don't short circuit on the line, and then set a heat shrinkable tube outside, the lighter can't be seen from a distance, and it is very strong and not easy to break.

The cord of earphone and earplug is broken. How to connect?

The headphone cable is broken. The connection method is as follows:

1. Put on headphones, plug in the audio source, play music, then bend the power cord 90 degrees with your thumb, straighten the earphone cord, and then try it down along the plug of the power cord. In the broken place, the sound sounds loud, broken and unstable. You can bend or twist this point again to see if there is anything wrong with it. After finding it, paste it with electrical tape.

2. Slide the shrink tube down and try again. The shrink tube looks similar to the rest of the headphone cable. If the earphone is damaged, you can use this shrink tube to replace the damaged part. Use the contraction tube quickly After the wires are welded, they can't be used.

3. Use the wire stripper to open the gap of 1.25cm .. You can carefully cut the knife on the wire cover with a knife instead of cutting off the articles. In this way, we can see that the two lines are separated (left channel and right channel), so the channels are different. The copper in the middle is used to separate the two wires. In other cases (Apple headphones, etc. ), in addition to the two channel cables, there is also an exposed ground wire.

4. Sew the thread together. You can use two methods: twisting or embedding joints. In a twisted joint, two exposed parts are placed in parallel and then connected in circles. When connecting, please pay attention to connecting red, white and white lines of the same color. The ground wire is relatively simple and can be all connected together.

5. Welding connection. Weld all joints on all joints and let them cool. After cooling, tie two pairs of connectors to ensure that the red and white wires are separated from the ground wire.

6. Place the shrink sleeve on the fracture and heat it. After heating, the shrink sleeve will shrink to a quarter of the original size, which can make the repaired thread more firm.

The earphone cable is broken, why can't it be welded?

That earphone repairman is farting. There is no reason for poor welding, but he used some precision equipment to prevaricate your poor welding!

Although we know that there are sophisticated welding equipment that can be welded, isn't it worthwhile to buy a set of equipment for one of our own earphone cables? In fact, the difficulty of this kind of welding lies in:

1. There is enamel outside the wire, or there is insulation outside, which may hurt the enamel or insulation.

2. Some wires are aluminum wires, which do not stick to the general welding method and form virtual welding.

The above solution:

1. By controlling the welding temperature, such as welding with low-power soldering iron and low-temperature solder, the insulating layer on the surface can be carefully cleaned mechanically, and in the case of local welding, the influence on other places should be relatively small.

2. Use special aluminum wire solder, such as the working melting point of M5 1 179 degrees, and the feel of 45W soldering iron is enough. Don't forget to assist in the welding of M5 1-F flux, and wipe it gently with alcohol after welding. You can search for "M5 1 Low Temperature Welding Video of Copper-Aluminum Welding" in the SOSO search bar.

If you still don't understand, you can add QQ and ask directly.

How to weld the broken earphone cable?

How to weld the broken earphone cable;

One of the four wires is a male negative electrode, one is a microphone, and the other two are left and right channels. Different earphones sometimes have different colors, which can't be judged by color alone, but generally the yellow line is the male * * * negative electrode. You can put on headphones and try to touch them with wires at both ends of the battery. If there is slight noise at both ends at the same time, these two lines are channel lines. If there is no noise, one of them is a microphone, while the left earring is a left channel, and the other is a common negative electrode. So is the right ear. It will be more convenient if there is a multimeter to measure resistance. The resistance between the left and right channels and the negative electrode is generally greater than ten ohms, while the resistance between the left and right channels is twice that of the negative electrode. The microphone has a high resistance. After judgment, the connection mode of the four-level earphone plug of the general Android device is left channel, right channel, negative electrode and microphone from top to bottom. In the case of Apple, the negative electrode and microphone are the other way around. Note that the wire control of headphones is compatible. If the headset designed for Android is defined by Apple's plug, the volume can't be increased or decreased. or vice versa, Dallas to the auditorium

The earphone cable is broken, why can't it be welded?

That's not true! That's an excuse that people don't want to help you!

If you have a low-power soldering iron (25W), you can weld according to the general circuit welding method, so don't ask them!

Or find an acquaintance who is a little skilled in this field and can help you weld! -it is common to do something!

For reference only!

You don't have a score reward either. There will be an extra score reward if you use the system within 2 minutes! -Thank you.

What if the headphone cable is broken? There are no tools welded together.

Go to the TV repair shop for free to weld for you.

This is the headphone cable. I broke it. How do I weld the end of the cable? earphone

Your plug is broken, it is not easy to weld. Buy a new plug, and each connection point has welding tabs, which is very convenient for welding.

Welding is a skill, the solder joint should be clean and bright, the plug should be fixed (it can be clamped by a clothespin), solder wire should be held in the left hand and soldering iron in the right hand, and solder wire should be placed on the solder joint. The welding head should be pressed down quickly, and the solder should be lifted immediately after melting, so that the solder resist in solder wire will not be completely vaporized and left on the solder joint (the solder joint is very bright). This step is called tin plating. The earphone cable should also be tinned.

Place the head of the tin-stained earphone cable on the tin-stained welding piece, and gently press it with a soldering iron to weld it.

Beginners should not use lead-free solder, because it has a high melting point, and then use it after proficiency.

Is there any way to weld the broken earphone cable? How to connect the red, yellow, blue and green heads?

The earphone cable is red, yellow, blue and green, not an earphone with a microphone, and the connection is relatively simple.

These four wires are connected to the earphone plug, and the earphone head has three welding points, namely, welding ground wire, right channel and left channel.

The four wires in the earphone, the other two are the same, both are main wires, that is, ground wires. Generally, these earphone wires are bilateral wires, usually red and yellow are ground wires, main wires, and blue or green are left and right channels.

But the wiring mode of this different factory is different. It's best to test it with a multimeter and connect it better. It can be used under normal connection.

How can I answer the earphone cable if it is broken?

No skill, line to line

Left channel to left channel, right channel to right channel, ground wire to ground wire.

You said there was no sound.

, headphone cable at least three lines, three colors.

This color coating is insulating.

Wires of the same color are hung with blades to expose the metallic color of copper wires and then welded together, or directly screwed on.

Be careful not to short-circuit the three wires.

Just connect it, then cover it with a heat shrinkable tube and burn it with a lighter.

You can't see it from a distance.

And it's strong. It won't break any more.

How to connect the earphone cable if it is broken? Whether to weld with insulating tape or electric soldering iron. I see. Come on in.

You find the other end according to the color of the broken wire and burn the broken end with a lighter. The purpose is to burn the insulating glue, and then connect the wires of corresponding colors together, so that you can weld or wind them together. Then wrap the thread separately with ordinary tape. Because the voltage of the earphone is very low, insulating glue is not used. I hope you succeed!

How to connect the earphone cable when it is broken in the middle?

Yes, as long as you find the broken place and screw up the metal wire. If there are too many broken places, just change the line.

You did your best. No, there may still be a turn for the better.

The cord of earphone and earplug is broken. How to connect?

Answer it yourself. The sound is connected correctly.

Welding by yourself or others. Have tools. Look at the gestures.

If it's not expensive, slowly dismantle another comparison.

Change another car and drive it for a while.

How to connect the earphone cable if it is broken?

How to disconnect the headset cable:

1. Winding: If the earphone cable is broken, bake the inner copper wire with a lighter, remove the outer paint layer, and then continue the connection by winding. The method is the same as wiring. However, it should be noted that the copper wire inside the earphone is relatively thin, so be careful not to burn the copper wire when removing the paint layer. The interface in this way is not seamless, and the more connectors there are, the more unstable the audio signal transmitted by headphones will be.

2. Welding: If conditions permit, the best way to connect the earphone cable is to connect the broken earphone cable with a welding gun and solder without dismantling the original earphone cable. If you want to restore the headphones to their original state as much as possible, the safest way is to weld the copper wires of the sports headphones together with a welding gun and solder.

3. Change the cable: This method is the best way to solve the problem of broken earphone cable. No matter what kind of earphone, it is generally divided into earphone, wire, volume controller and plug, and there will be a "welding point" between earphone, volume controller and plug. Using the welding gun, all the wires of the earphone can be melted directly, and then a new earphone wire can be melted again. As long as the wire is soldered to the receiver, volume controller and audio plug again, the earphone can be used normally.

How to connect the broken head of earphone?

Question 1: How to connect the earphone plug if it is broken? Red, Zuo Lan, right and yellow are shielding.

Question 2: As shown in the picture, the headphone cable is broken. How to connect? It just broke at the fork on both sides, so it is easy to connect. I took it. You use fire, preparation, lighter, soldering iron, welding wire and tweezers to test the adhesive layer of the broken contact. After exposing the copper wire of the glue line, burn the copper wire with a lighter, bake off the paint on it until it turns red, then turn on the phone and let go of * * *, plug in the earphone and put it on. Find one contact after another.

Question 3: The earphone connector is broken. How to connect the earphone disconnection usually occurs behind the earphone plug, the earphone branch line and the earphone unit outlet.

At the earphone plug, when the earphone is in poor contact. There is a reaction force at the moving plug, which means the broken line is here. Cut the headphone cable from here. Then strip the wire to find the broken part and cut the wire core neatly. The1* * line has four lines, namely left channel, left channel ground and right channel.

Channel and right channel are distinguished by color.

For the plug is three-pole, the ground of the left and right channels is connected together, and the earphone wire is coated with insulating paint, so it cannot be measured directly with an electric meter. The thread ends should be tinned first.

The specific operation method is to coat rosin or solder paste on the wire first, and then iron it with a soldering iron dipped in tin until the solder soaks the wire. Then it is best to disassemble the earphone shell, measure four wires with a meter, and check other broken wires. If it is normal, there is only one disconnection. Then peel off the soft cover outside the earphone head and put it on the wire, and cut the hard plastic behind the plug with a blade to expose the solder joint. Then weld the first wire. Generally, two ground wires are welded in the thickest place, the right channel is welded in the middle and the left channel is welded in the thinnest place. Generally, two yellow lines are ground lines, the red line is the right channel, and the green line is the left channel. Of course, there are exceptions, so it is better to take the unit apart and measure it. After welding, check to prevent two short circuits.

Question 4: How to connect the four headphone cables when they are broken? If it is broken in the middle, it is easy to burn the paint on the wire, then scrape it with a knife and screw it together, put on a heat shrinkable tube and point it with solder.

If I want to call you,

The meaning of line color varies from manufacturer to manufacturer.

First, make sure that the speaker end of the earphone is not broken.

Then you put on your headphones and take a multimeter to measure Ohm × 100 (the magnification is small enough to shock your ears and large enough to be inaudible). One pen is connected to the yellow wire (the male * * ground wire and the negative electrode are usually fixed in color), and the other pen is connected to the other three wires respectively. If you touch a line, the left ear rings, which means it's the line of the left channel, and the right ear rings, which means it's the right channel, and the silent one is Mike.

The end point on the other side of the plug is the first part. From the first section, it is the left and right wheat fields (American standard white circle) or the left and right wheat fields (national standard black circle), generally in the national standard.

Then adjust the soldering iron to the solder joint of about 270. I repaired a lot of these headphones.

Question 5: How to connect the plug when the earphone cable is broken? Find a repair shop for a simple repair, or simply buy a new one.

Question 6: How to connect the computer earphone cable when it is broken? General situation: green and red are connected to the positive pole of the left earphone and the right earphone respectively, and yellow is connected to the negative pole. The other microphone is blue and the other is yellow, which are connected to the positive and negative poles of the microphone respectively.

In fact, you can plug them into the computer and try them one by one. Remember that the enameled wire is insulated, and tin should be added with an electric soldering iron! !

Question 7: The earphone cable is broken. How to connect? Gently cut the connector with a knife (near the thin wires), cut off the three thin wires, and then bake quickly with a lighter to remove the insulation. Just connect the connector side 3 wire with the earphone side wire. Of course, it's best to wrap it up and don't touch the wire for short circuit. If you don't know which line to connect, you can try to connect several lines. Headphones are low voltage, even if the short circuit is wrong, it doesn't matter much until there is sound.

Question 8: How to connect the broken earphone cable? How to connect the headphone cable? Where can I get the discarded earphone plug? It's easier to remember to burn off the paint on the surface with a lighter first. It is best to have a heat shrinkable tube to cover the plug. If you pull it out frequently, it won't be long before it breaks down.

Question 9: How to answer if the earphone is disconnected? Check whether there is color difference on the wire sheath. If there is, just connect it with the right color. If not, try the corresponding connection first, and then listen to the headphones. If it is normal, it will be bandaged. If it is not normal, it will be proved wrong. Just change the connector.
