As described in the background art, computer cables in the prior art are usually either suspended in the air or buried underground for wiring, and during use, the cables laid in the air are prone to aging because of exposure to rain and sunshine, causing that the surfaces thereof crack and are particularly liable to cracking when subject to stresses imposed on bent positions.
Although the cables buried underground may be sheltered from rain and sunshine, the acid-base properties at different positions in the soil are not consistent, likely leading to local corrosion of the cable surfaces; also, the soil in some places is hollowed or loosened under the action of rain erosion, and there is a certain degree of slippage or collapse in the soil, resulting in excessive bending and stretching of the cables, and thus causing cracks appearing on the cable surfaces.
However, inthe prior art, it is common to find that the cable is damaged only after the cable breaks, and it is difficult to find the position of breakage. It is required to detect along a wiring route, and the working efficiency is low. In case that only a protective layer is broken, it is difficult to find thät}501991 the cable is damaged, and at this time, the wires inside the cable are in contact with external media (especially water and moisture), easily causing electric leakage and affecting the stability of signal transmission of the cable.

When the cable is used for a long time, if there are multiple cracks, the cable can be heated by using hot air to transfer heat energy from the internal space of the inner protective layer 210 after the cable is moistened by rain, thereby evaporating the cable to dryness, avoiding electric leakage and reducing interference of water in electric signals.
