[0002] With the rapid development of modern society and the continuous advancement of science and technology, people are paying more and more attention to the safety issues of various electronic products, and the quality and functional requirements of electronic products are also getting higher and higher. The importance of connecting cables as a carrier for data and power exchange between devices, devices and machines, and machines and machines is self-evident.

[0003] When in use, the connecting cable is often restricted by site conditions. The connecting cable will come into contact with the ground, and may be bent to a certain extent when in use. The movement of the connecting cable will cause friction on its surface. Over time, if the wear resistance of the connecting cable is poor, the life of the connecting cable will be greatly reduced, thus affecting subsequent use.

[0004] Therefore, we propose a highly wear-resistant connecting wire to solve the above problems. Utility Model Content

[0011] Compared with the prior art, the utility model has the following beneficial effects:

The wear-resistant protective layer is a three-layer structure. The nylon braided layer is a nylon braided wire sleeve, which has good wear resistance and improves the wear resistance of the connecting line. The rubber layer is made of halogen-free low-smoke flame-retardant polyolefin, which makes the connecting line have good wear resistance on the one hand and is not easy to burn on the other hand.
