AI Technical Summary

Technical Problem

Traditional communication harnesses are susceptible to mechanical stress and electromagnetic interference in new energy vehicles, leading to unstable signal transmission, cable breakage, and serious contact problems.

Method used

The cable surface is wrapped with aluminum foil to shield low-frequency magnetic fields, filled with silicone to absorb vibration energy, and the inner layer of the rubber ring with braided mesh to enhance high-frequency shielding. The outer layer of metallized fabric improves the overall shielding performance. The sliding of the rubber ring and the sliding of the connecting block, in conjunction with the spring wire, offsets external impact forces and ensures a stable connection.

Benefits of technology

It improves the mechanical strength and signal transmission stability of the communication harness, enabling stable signal transmission in complex electromagnetic environments, avoiding poor contact between cables and terminals, and enhancing the harness's anti-interference capability.

Abstract

This invention belongs to the field of communication wiring harness technology, and specifically to a novel high-strength communication wiring harness for automobiles. A rubber ring is slidably connected to the inner wall of the terminal head, and a protective component is fixedly connected to the surface of the rubber ring. The internal wiring of the terminal head is connected to a wiring harness assembly, which includes a spring wire. The protective component includes a connecting block. This invention utilizes silicone filling in the inner layer of the rubber ring to absorb vibration energy, reducing fatigue damage to the wiring harness caused by vibration. A braided mesh is used in the middle layer of the rubber ring to enhance the shielding effect against high-frequency electromagnetic fields. An outermost layer of metallized fabric further enhances the overall shielding performance. The rubber ring slides along the inner wall of the terminal head to transmit external impact forces. The connecting block compresses the connecting spring, and the spring's rebound is buffered by the friction between the rubber ring and the inner wall of the terminal head, ensuring the stability of the connection between the cable and the internal wiring of the terminal head.
