Description
Technical Field
[0001] This utility model relates to the field of automotive wiring harness technology, and in particular to a protective automotive wiring harness. Background Technology
[0002] With the rapid development of the automotive industry towards electrification and intelligence, the research importance of protective automotive wiring harnesses is becoming increasingly prominent. Modern automotive electronic and electrical systems are becoming increasingly complex, with a significant increase in the number of ECUs. The application of high-speed communication protocols places higher demands on the electromagnetic interference resistance of wiring harnesses. Meanwhile, the high-voltage systems of new energy vehicles bring new technical challenges such as insulation withstand voltage and arc protection. In terms of environmental adaptability, wiring harnesses need to withstand extreme temperature changes from extreme cold to high temperatures, as well as multiple tests such as vibration and shock, chemical corrosion, and waterproofing and dustproofing. This poses a severe challenge to the weather resistance and structural reliability of wiring harness materials. Traditional automotive wiring harnesses are subjected to repeated vibrations, bending, and impacts during use, making them highly susceptible to damage and affecting the overall quality of the vehicle. Therefore, a protective automotive wiring harness needs to be designed. Utility Model Content
[0003] The purpose of this utility model is to provide a protective automotive wiring harness to solve the defects of existing protective automotive wiring harnesses, which are easily damaged during use due to repeated vibrations, bending and impacts, which affects the overall quality of the vehicle.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a protective automotive wiring harness, including an inner core; The outer core is uniformly wound around the outside of the inner core; A protective structure is fixed to the outside of the outer core, and a reinforcing structure is fixed to the outside of the protective structure. The reinforcing structure includes a noise reduction layer, a wear-resistant layer, and a corrugated pipe. The noise reduction layer is fixed to the outside of the protective structure, the wear-resistant layer is fixed to the outside of the noise reduction layer, and the corrugated pipe is provided on the outside of the wear-resistant layer.
[0005] Furthermore, the outer cores are evenly distributed on the outside of the inner cores.
[0006] Furthermore, the protective structure includes a fixing layer, an insulating layer, and a shielding layer. The fixing layer is fixed to the outside of the outer core, the insulating layer is fixed to the outside of the fixing layer, and the shielding layer is fixed to the outside of the insulating layer.
[0007] Furthermore, the fixing layer is a nylon tape layer, and the insulating layer is a PVC layer.
[0008] Furthermore, the shielding layer is a woven copper mesh layer.
[0009] Furthermore, the noise reduction layer is a velour tape layer.
[0010] Furthermore, the wear-resistant layer is a polyester layer.
[0011] The protective automotive wiring harness provided by this utility model has the following advantages: By incorporating a reinforced structure, a noise-reducing layer is attached to the outside of the protective structure. The damping properties of the fleece absorb vibration energy, reducing abnormal noises caused by friction between the wiring harness and the vehicle body. The wear-resistant layer is a high-strength fiber braided layer that is tear-resistant and abrasion-resistant, preventing gravel or assembly tools from scratching the outer layer of the wiring harness. The spiral corrugated structure of the corrugated tube provides rigid protection against compression and impact. Its corrugated design allows the wiring harness to stretch and contract when bent, avoiding breakage. This device enables easy protection of the wiring harness and improves the service life of the protective automotive wiring harness. With its protective structure, the fixing layer possesses high tensile strength and flexibility, buffering external vibrations and impacts to prevent the wiring harness from breaking due to long-term bending fatigue. The insulation layer provides basic insulation, is acid and alkali resistant, and moisture-proof, preventing conductor short circuits. Its flexibility also adapts to the bending requirements of the wiring harness. The shielding layer covers the outer layer, forming a Faraday cage effect through a dense copper mesh, effectively shielding high-frequency electromagnetic interference and ensuring signal transmission stability. This device enables convenient insulation and shielding of the wiring harness, improving the safety of the protective automotive wiring harness during use. Attached Figure Description
