AI Technical Summary

Technical Problem

Under frequent bending or dynamic bending, traditional cables are susceptible to damage, insulating layers are easily damaged, and conductors are prone to breakage, resulting in frequent electrical failures, shortened service life, increased equipment maintenance costs and increased risk of shutdown.

Method used

Design a flexible cable that is resistant to bending, including a central rubber section, annular engineering plastic section and a tubular protective rubber section. A cable is installed on the inner side, and a directional limiting mechanism is installed on the inner surface of the engineering plastic section, through functional rings, limiting rings, Components such as tooth blocks and drive gears control the winding direction and degree of cables to reduce damage during bending.

Benefits of technology

It effectively protects the cable insulation layer from stretching and extrusion, extends the service life of the cable, reduces the failure rate and maintenance cost, and improves the bending resistance and reliability of the cable.

Abstract

The invention is applied to the technical field of cables, and discloses an anti-bending flexible cable which comprises a central rubber section, the two ends of the central rubber section are fixedly connected with one end of an annular engineering plastic section, the other end of the engineering plastic section is fixedly connected with a protective rubber section, and the protective rubber section is of a tubular design. Cables are arranged on the inner sides of the center rubber section, the engineering plastic section and the protective rubber section, a directional limiting mechanism is arranged on the inner side surface of the engineering plastic section, and damage to the cables when the cables are bent is reduced by controlling the winding direction and the winding degree of the cables. According to the anti-bending flexible cable, the cable is spirally wound in the outer layer protection formed by the central rubber section, the engineering plastic section and the protection rubber section, and the spiral winding state of the cable is released when the cable is bent, so that the length of the cable can be extended in an unfolding manner; therefore, when the cable is bent, the insulating layer on the surface of the cable is not stretched and extruded.
