Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive wiring harness fixing technology, and in particular relates to an automotive lighting wiring harness fixing device. Background Technology
[0002] Automotive wiring harnesses are the core of a vehicle's electrical network; without them, there is no automotive electrical system. A wiring harness is an assembly consisting of copper-plated contact terminals (connectors) crimped to wires and cables, then covered with a molded insulator or an outer metal shell, and bundled together to form a connected circuit. Classified by application area, automotive wiring harnesses include engine wiring harnesses, body wiring harnesses, and chassis wiring harnesses. Automotive wiring harnesses need to be secured to the vehicle body using fixing devices or clips.
[0003] A search revealed a patent with application number 201821528856.6, which discloses an automotive wiring harness fixing device. This patent uses an elastic fixing sleeve on the outside of a circular base plate and an adjusting bolt and a pressure plate inside the elastic fixing sleeve to fix wiring harnesses of different specifications separately, thereby improving the fixing strength of the wiring harness. However, the vibration that occurs when a car is in motion still poses a risk of the wiring harness coming off the opening of the elastic fixing sleeve. Utility Model Content

By setting an outer disc and an inner disc, and connecting the outer disc and the inner disc by fastening bolts, and both the outer disc and the inner disc have arc-shaped wiring harness holes at their contact parts, the combination of wiring harness holes between the outer disc and the inner disc is closed, which can effectively prevent the wiring harness from detaching from the wiring harness holes and improve the stability of use.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A car lighting wiring harness fixing device includes a base; mounting holes are provided at both ends of the base; two symmetrical support rods are fixed on the base; an outer disc is fixed to the upper end of the support rods; a through groove is provided in the middle of the outer disc, and an inner disc is engaged in the through groove; an extension plate is provided on the outer side of the inner disc, and the extension plate is connected to the outer disc by fastening bolts; wiring harness holes are provided at the contact parts of the outer disc and the inner disc; the wiring harness holes are arc-shaped and are equidistantly arranged around the central axis of the inner disc; by setting the outer disc and the inner disc, and connecting the outer disc and the inner disc by fastening bolts, and providing arc-shaped wiring harness holes at the contact parts of the outer disc and the inner disc, the combination of wiring harness holes between the outer disc and the inner disc is closed, which can effectively prevent the wiring harness from detaching from the wiring harness holes and improve the stability of use.
[0007] Furthermore, each of the wiring harness holes is equipped with a rubber pad, which improves the protection of the automotive wiring harness.
[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting an outer disc and an inner disc, and connecting the outer disc and the inner disc by fastening bolts, and opening wire harness holes with arc-shaped structures at the contact parts of the outer disc and the inner disc, the combination of wire harness holes between the outer disc and the inner disc is closed, which can effectively prevent the wire harness from detaching from the wire harness hole, thus improving the stability of use. By setting rubber pads in the wire harness hole, the protection effect of the automotive wire harness is improved. Attached Figure Description
