AI Technical Summary

Technical Problem

The existing high-voltage wiring harnesses for charging piles have a simple design for insulation, shielding, and external protection, which makes it difficult to balance electromagnetic interference resistance, weather resistance, and mechanical wear resistance. This results in insulation aging, shielding failure, and poor installation compatibility. The wiring harnesses are also prone to displacement and wear due to vibration, affecting their service life and heat dissipation.

Method used

The protective device adopts a three-layer structure, including an inner insulation layer, a shielding layer, and an outer protective layer. Combined with an arc-shaped connecting block, cable tie, and Velcro mounting device, the device enhances contact stability through serrated protrusions and ensures secure installation with screws, achieving multi-layer protection and uniform fixation.

Benefits of technology

It improves the insulation, electromagnetic interference resistance and weather resistance of the wire harness, reduces the risk of insulation aging and shielding failure, enhances the stability and adaptability of installation, extends service life and improves heat dissipation.
