AI Technical Summary

Technical Problem

Existing low-voltage cables have problems with electrical performance, anti-interference ability, mechanical strength and service life in complex environments. In particular, they are prone to slippage or delamination between layers in scenarios with frequent bending or movement, which affects the overall structural stability. At the same time, they need to meet heat dissipation requirements and bending resistance.

Method used

An insulating layer, a shielding layer, and a protective layer are sequentially arranged on the outer side of the core to form a gradient protection system. Combined with a detachable protective structure, heat dissipation components, and anti-bending strips, the layers are tightly bonded through limiting clips and adhesive strips to enhance structural stability. The heat dissipation requirements are met through silicone pads and heat dissipation channels.

Benefits of technology

It significantly improves the electrical performance, anti-interference ability, mechanical strength and service life of the cable, ensures structural stability and meets the comprehensive performance requirements in complex environments.

Abstract

This invention relates to the field of cable technology, specifically to a low-voltage cable with a protective structure designed to resist bending. The cable includes a detachable protective structure fitted over the outer side of a protective layer. The two ends of the detachable protective structure are staggered and stacked. A heat dissipation assembly is located between the detachable protective structure and the protective layer. Furthermore, an anti-bending strip is embedded in the outer wall of the detachable protective structure. The advantages are: the detachable protective structure allows for flexible installation according to laying requirements; it is fixed by staggered splicing through splicing grooves and adhesive strips, with limiting clips enhancing its firmness and facilitating easy assembly and disassembly; the silicone pad in the heat dissipation assembly increases friction to prevent loosening and absorbs heat, which is then dissipated through heat dissipation channels, meeting heat dissipation needs; the anti-bending strip embedded in the outer wall of the outer protective sleeve enhances the cable's tensile and torsional resistance; the flexible buffer layer absorbs external impact energy; and the rubber sheath prevents wear and increases friction, comprehensively improving the cable's overall performance in complex environments.
