Compression-resistant and wear-resistant coaxial cable

Abstract

The present invention discloses a compression-resistant and wear-resistant coaxial cable. The coaxial cable comprises a rubber protective sleeve, a wear-resistant layer, wire cores and cable center bodies. One end of the inside of the rubber protective sleeve is provided with an external insulation layer, and the central location of the inside of the rubber protective sleeve is provided with the cable center bodies uniformly. The wire cores are uniformly arranged between the cable center bodies and the external insulation layer. The outside of each wire core is provided with a protective sleeve, the central location of the inside of each wire core is provided with conductors, and the outside of each conductor is provided with an internal crust. The other end of the inside of the rubber protective sleeve is provided with the wear-resistant layer, and a metal mesh layer is arranged between the wear-resistant layer and a buffer layer. According to the coaxial cable, by providing the buffer layer, a damping spring and reset springs uniformly arranged at the outside of each conductor, even if the coaxial cable is deformed under an external force, the coaxial cable can restore to the original state quickly after the external force is disappeared, and thus the cable can not be damaged.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a pressure-resistant and wear-resistant coaxial cable. Background technique [0002] With the continuous development of society and the rapid improvement of people's living standards, the wire and cable industry is the second largest industry in China after the automobile industry. The product variety satisfaction rate and domestic market share both exceed 90%. Worldwide, China The total output value of wire and cable has surpassed that of the United States and has become the world's largest producer of wire and cable. Coaxial cable refers to a cable with two concentric conductors. The name of coaxial cable is related to its structure. Coaxial cable is also used in local area networks. One of the most common transmission media. [0003] However, there are some problems and limitations in the current coaxial cables. Most of the coaxial cables have poor extrusion resistance, which ...

AI Technical Summary

Problems solved by technology

[0003] However, there are some problems and limitations in the current coaxial cables. Most of the coaxial cables have poor extrusion resistance, which makes it easy to produce irreversible deformation when squeezed, causing damage to the coaxial cable and shortening the length of the coaxial cable. The service life of the cable, at the same time, this type of device is susceptible to external interference, and the performance is not good. In addition, the cable is mostly used outdoors. If the function of wear resistance is insufficient, it is also easy to be damaged during construction and use, which will affect the use. , in addition, the current coaxial cable structure strength is not high, and the stability of transmission cannot be guaranteed, so there is an urgent need for a pressure-resistant and wear-resistant coaxial cable to meet people's needs
