Description

Technical Field

[0001] This utility model relates to the field of wiring harness technology, and in particular to an automotive wiring harness for preventing loosening. Background Technology

[0002] In automotive electrical systems, wiring harnesses are the core carriers connecting various electrical components, and their installation stability and integrity directly determine the safe operation of the vehicle's circuitry. Wiring harnesses are mostly located in engine compartments and areas with densely packed components, placing extremely high demands on their fixation reliability, damage resistance, and ease of installation, making them difficult to adapt to the complex use and maintenance needs of automobiles.

[0003] Existing automotive wiring harness fixing structures suffer from poor stability and lack effective protection. Most existing harnesses rely on single cable ties, simple clips, or single-layer slots for securing them. These single-method fixing lacks multi-position limiting structures, and the existing structures lack specific protective components. When the clips or slots are in direct contact with the wiring harness, vibration-induced impacts accelerate harness aging and shorten its lifespan. Furthermore, existing automotive wiring harness assembly and disassembly structures are cumbersome, resulting in low installation and maintenance efficiency. During automotive assembly, wiring harnesses require multiple adjustments and fixations, and during maintenance, frequent disassembly and reassembly are necessary for circuit inspection. Existing wiring harness fixing structures often employ screw locking, disposable cable ties, or complex clip designs. This cumbersome assembly and disassembly method reduces the operational efficiency of automotive assembly lines and fails to meet the automotive industry's production demands for "efficient assembly and convenient maintenance."
