Abstract

The invention discloses a cable reinforcement line. The cable reinforcement line comprises a fiber bundle and a colloid coating layer, wherein the fiber bundle is formed by twisting 5-2,000 fiber filaments, the twisting direction is an S direction or Z direction, the diameters of the fiber filaments are 1.5-5 micrometers, the fiber filaments is filled with a colloid adhesive which is a flexible adhesive, and the colloid coating layer is combined outside the filter bundle and is made of the flexible adhesive. By the cable reinforcement line, surface wildness of the fiber filaments can be prevented, the influence on the electrical properties of the cable is reduced, the wear resistance of the reinforcement line is enhanced, the toughness of the reinforcement line is improved, the phenomena of electric wire breakage, copper wire breakage, jumping, exposure and non-uniform twisting during the production process of the cable are reduced, and moreover, the situations of pseudo soldering and false soldering of a welding point occurring in subsequent welding of the cable can be improved. The colloid coating layer contains conductive powder, and the reinforcement line has the function of conductivity.

Description

technical field

[0001] The invention relates to the field of cables, in particular to a cable reinforcing wire. Background technique

[0002] Existing cables use reinforcing wires to increase the breaking force and swing performance of the copper wires, and are used to fill the cables. The existence of the reinforcing wire improves the tensile strength and swing performance of the cable, and can prevent the cable from breaking during the pulling process to a certain extent. However, the fibers of the existing reinforcing wires are easy to scatter, and the fiber bundles are easy to fluff, which will affect the electrical properties of the cable, and then affect the signal transmission of the cable; it will also affect the tensile force of the fibers and reduce the resistance of the cable. tensile strength. During the stranding process in the production and processing of the cable industry, due to the loosening of the fibers and fluffing on the surface, it is easy to block t...
