Fixed-point reinforced cable capable of automatically inhibiting bending angle

Abstract

The invention discloses a fixed-point reinforced cable capable of automatically inhibiting a bending angle, and belongs to the field of cables. According to the fixed-point reinforced cable, through arrangement of an outer multi-ball-point inhibition rod and an inner multi-ball-point inhibition rod, when the cable is bent, inner reinforcing balls at the bending portion can be gradually close to outer reinforcing balls corresponding to the inner reinforcing balls by the pushing force generated by bending, along with the increased bending angle, the inner reinforcing ball at the position can befinally clamped between the two corresponding outer reinforcing balls, on one hand, the strength of the contact part of the outer reinforcing balls and the inner reinforcing balls is obviously improved, and on the other hand, the two parts extrude each other to harden, thereby effectively improving the strength and hardness of the bending point, enabling the cable to effectively inhibit the continuous bending of the bending point, effectively inhibiting the bending range, effectively protecting the bending point of the cable from being aged and damaged, and reducing the potential safety hazardof long-term use.

Description

technical field [0001] The invention relates to the field of cables, in particular to a fixed-point reinforcement type self-suppressing bending angle cable. Background technique [0002] The cable is mainly composed of the following 4 parts. ① Conductive wire core: made of high conductivity material (copper or aluminum). According to the requirements of cable softness under laying conditions, each wire core may be formed by twisting a single wire or multiple wires. ②Insulation layer: The insulation material used for cables should have high insulation resistance, high breakdown electric field strength, low dielectric loss and low dielectric constant. Commonly used insulating materials in cables are oil-impregnated paper, polyvinyl chloride, polyethylene, cross-linked polyethylene, rubber, etc. Cables are often classified by insulating materials, such as oil-impregnated paper insulated cables, PVC cables, XLPE cables, etc. ③ Sealing sheath: protect the insulated wire core ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the problems existing in the prior art, the object of the present invention is to provide a fixed-point reinforcement type self-suppressing bending angle cable, which can be used by the cable through the setting of the outer multi-ball point suppression rod and the inner multi-ball point suppression rod. When bending occurs, through the thrust generated by bending, the inner reinforcing ball at the bending part will gradually approach the two corresponding outer reinforcing balls. As the bending angle becomes larger, the inner reinforcing ball at this position will eventually get stuck between the corresponding two outer reinforcing balls, on the one hand, the strength of the area after the contact between the outer reinforcing ball and the inner reinforcing ball is obviously improved, on the other hand, the two will become hard when they are squeezed together, thus effectively improving the bending point. The strength and hardness of the place, so that the cable itself can effectively restrain the continuous bending of the place, thereby effectively restraining the bending range, effectively protecting the bending point of the cable from aging and damage, and reducing the safety hazard of long-term use
