There is no danger if the charging cable is broken.

It won’t be a big problem if the outermost black layer is broken. There is an insulating film on the outside of the inner wires. Moreover, the voltage inside is only 5V, which is safe. Of course, it does not rule out absolute safety. , it is not safe to use an inferior charger or the charger has leakage, so it is best to replace it, just to be on the safe side.

The voltage of the charger is very low, so the danger is not great. The output voltage of mobile phone chargers is very low, usually only 5V. New mobile phones only have 9-12V, which is lower than the safe voltage of 36V and will not affect people.

How to repair broken charging cable

1. First, use a utility knife to cut the side of the casing, and gently pry it open to loosen the casing bit by bit until it comes out of the casing. .

2. Use a flat triangular file to polish the connecting points on the front and back until a scratch needle or a flat knife can be inserted into the gap and the shielding cover can be pried open.

3. Take off the white sheath, remove the solder joints at the bottom of the shielding cover, use a file, grind first and then pry.

4. Reshape the removed shielding cover for recovery.

5. To deal with the data line pad, you can directly solder and flatten it, or you can use a soldering iron to remove the wire, then remove the broken skin and broken wire, reserve an appropriate length to tin the new connection point, and solder it back. The solder pad must be covered with a white sheath, and heat-resistant insulating tape must be applied to the solder joints.

6. Recovery process: Fold the shielded ground wire back, close the two shielding covers, fix it with a clip, add solder to the point where the file has been ground, and finally grind off the excess solder. .

7. Put the white sheath back on, put on the shell, add some glue, fix it, and you will have a revived data cable.
