Not sure why, but the cat really enjoy chewing on the cords in our house. A particular favorite are headphone cables, USB cables and laptop power supply cords.
I’ve already shown a headphone repair here, so I will not go into too much detail on that, but the Lightning USB cable is a first.
Started the project by removing the section that was chewed up… in this case it was about 2″.
Next, carefully remove about 1″ of insulation on both pieces. Also, add a small piece of heat shrink tubing to each side, this will give the larger, final tubing something to grab on to and act as a strain relief.
Strip back the individual wire insulation, tin each wire and solder them together. Be sure to insulate each solder connection with some small heat shrink tubing.
To complete the project, slide the large piece of tubing over all the connections. No one will be fooled into thinking its a new cable, but it is electrically sound and a solid repair.
The ear buds are a similar process, but the wires are much smaller. A magnifier was used for the soldering process.
