AI Technical Summary

Technical Problem

The existing low-voltage controller wiring harness suffers from signal transmission distortion due to electromagnetic interference from high-voltage components inside the vehicle, and the sealing structure is prone to failure under vibration and impact, leading to controller malfunction and disorder of the vehicle's control logic.

Method used

It adopts a twisted pair shielding layer and a sealed structure. By twisting the wires in pairs and combining the aluminum foil shielding layer with the braided mesh shielding layer, the anti-interference ability is enhanced. The interference fit between the sealing plug and the housing and the design of the locking bracket ensure stable signal transmission and sealing.

Benefits of technology

It effectively suppresses electromagnetic interference, ensures stable signal transmission, prevents sealing structure failure, improves the mechanical strength and sealing reliability of the wire harness, prevents terminal pin retraction and misalignment, and ensures the stability of the wire harness under vibration and impact.
