When the outer skin of the data line is damaged, there is usually no danger. If the copper wire inside is exposed, it is recommended to replace it for absolute safety. The data cable belongs to low voltage, which will not affect the human body under normal circumstances, but improper contact may cause the charging head to burn out.

Repairing with insulating tape should be the easiest way to think of. Just wrap insulating tape around the broken data line twice, because insulating tape is sticky and not easy to loosen. If the tape is loose after winding, you can take down the used tape and rewind it several times, which is also very convenient.

There are some data line protection packages on the Internet, which can be used not only for new data lines, but also for a great effect even if the data line is broken. But it takes a lot of effort to wind the data line, and it takes about an hour to completely wind the whole data line.

Matters needing attention in data cable maintenance

1. If you want to effectively guarantee the service life of the data cable, you need to cherish it more when using it. Many consumers and friends may not pay much attention to it, and it is easy to pull out the data cable when plugging it in and out. Even some consumer friends will remotely pull the data cable and disconnect it from the charging head, but this is a big taboo for USB data cables.

Repeated pulling has no effect in a short time, but quantitative change will cause qualitative change. The regular data cable production company pointed out that pulling the data cable hard is the main reason for the data cable damage. Therefore, when unplugging the data cable of the mobile phone, don't be so simple and rude, be gentle and pay attention to the plugging and unplugging method.

2. Avoiding the heat source is a good protection for USB data cable. Although all the data cables on the market now have high-end data cables with fire protection, the skin of the data cables is mostly gelatinous. If it is close to the heat source, it will cause thermal expansion and cold contraction. With the increase of times, the data line may be broken. Therefore, attention should be paid to avoid being close to the heat source when using the data cable.

3. You can install a spring protection interface for the data cable, which is also the most popular way to protect the USB data cable on the Internet. This method is very simple and almost free. Just take out the used ballpoint pen spring, then stretch it, slowly wind it around the data line, and then rotate it to fix it. But in this process, you need to pay attention, be careful to scratch your hand.
