[0003] The common network cable on the market mainly has three kinds of twisted pair, coaxial cable and optical cable, among which the twisted pair is composed of many pairs of data transmission lines, and the characteristic is cheap and stable performance, so it is widely used. Taking the twisted pair as an example, the twisted pair adopts a pair of mutually insulated metal wires to resist a part of external electromagnetic wave interference, that is, two insulated copper wires are twisted together at a certain density, which can reduce the degree of signal interference, and the electromagnetic wave radiated by each wire in transmission can be offset by the electromagnetic wave emitted by the other wire. The name of "twisted pair" also comes from this. The twisted pair is generally composed of two 22-26 insulated copper wires, and in actual use, the twisted pair is composed of many pairs of twisted pairs in an insulated cable sleeve. The typical twisted pair has four pairs, that is, four pairs of twisted pairs are placed in an electric cable sleeve. This is also commonly known as twisted pair cable. However, the service life of the traditional network cable is poor, the durability is not high, and it is easy to break due to bending. In actual use, the other two types of network cable and the twisted pair type all have poor structure and performance, insufficient strength, and poor stretching and bending performance. These problems need to be further improved and improved. CONTENT OF THE UTILITY MODEL
