AI Technical Summary

Technical Problem

Cables used in industrial applications, such as those in industrial robots, suffer from insufficient resistance to repeated bending, twisting, and swinging operations, leading to potential disconnection of braided shields due to rubbing between adjacent signal lines.

Method used

A cable design featuring a collective core of twisted electric wires, each with a pair of insulated wires forming a twisted pair, a metal tape with a resin layer and metal layer, a braided shield, and a protective resin tape layer to enhance resistance to bending, along with a sheath covering the entire structure.

Benefits of technology

The design significantly improves the cable's resistance to bending and reduces the risk of disconnection, maintaining electrical integrity under repeated mechanical stress.
