AI Technical Summary

Technical Problem

The lack of effective buffering structures in drone wiring harnesses at strong vibration sources makes them prone to damage, affecting their service life and power transmission stability.

Method used

A helical buffer section is set at the connection point of the strong vibration source of the wire harness body. It adopts a combination design of oxygen-free copper core, nickel plating layer, silicone rubber insulation layer and protective reinforcement layer, combined with 7-strand/19-strand stranded structure to enhance flexibility and vibration resistance, and absorb vibration energy through buffer design.

Benefits of technology

It effectively prevents the wiring harness from being damaged by vibration, improves the wiring harness's high temperature resistance and vibration fatigue resistance, and ensures the stability and durability of power transmission.
