The wiring harness fixing device has the advantages of being low in production cost, convenient to assemble and the like.

Description

Technical Field

[0001] The utility model relates to a skylight structure, in particular to a wire harness fixing structure. Background Art

[0002] With the development of the automobile industry, more and more cars are equipped with sunroofs, and car sunroofs have gradually become mainstream; however, the assembly of the sunroof wiring harness is prone to problems such as difficulty in installation and easy detachment during the production process. Traditional wiring harnesses are often fixed by bundling them at a fixed distance and sticking them on the sunroof frame with adhesive tape, which has poor identifiability, firmness and stability. The existing wiring harnesses are fixed by installing a card holder on the frame, and the card holder is welded or bolted to the frame, which increases the production parts and production time, and increases the assembly production cost. Summary of the invention

[0003] The utility model provides a wire harness fixing structure which has a simple structure and is beneficial to stabilizing the clamping and fixing performance and reducing the production and assembly costs.

[0004] The technical solution adopted by the utility model is: a wire harness fixing structure, characterized in that: it includes left and right clamps which are stamped and formed by the opening of a frame plate surface and symmetrically clamp the wire harness, the left and right clamps are tilted and gathered toward the middle from bottom to top, the left and right clamps both include a clamp body and a clamp hook, the lower end of the clamp body is connected to the opening of the frame plate surface, the clamp body is terminated with the clamp hook, the outer opening of the clamp hook is set as a closing surface tilted inward from top to bottom, the clamp hook under the closing surface is a hook head structure, and the hook head is an arc structure; the inner wall of the clamp body is glued with a rubber pad.

[0005] The upper end of the clamp hook is an arc-shaped structure.

[0006] The distance between the hooks of the left and right clamps is less than 1 mm of the wire harness diameter.

[0007] The distance between the rubber pads on the left and right clamps is greater than 2 mm of the wire harness diameter.

[0008] The inner surface of the rubber pad is rolled with patterns or provided with anti-skid edges or frosted.

[0009] The beneficial effects of the utility model are as follows: no additional clamping parts are required, which helps to reduce production costs and assembly time costs; the left and right clamping head structures are directly stamped and formed on the frame, and the clamping heads are tilted and folded, and combined with the closing surface of the outer opening of the clamping head hook, the wire harness can be pressed down from the closing surface more conveniently and safely, so that the hook heads of the two clamping head hooks are opened and sent into the wire harness into the clamping head body, and the rubber pads in the clamping head body elastically constrain the left and right and front and back displacements of the wire harness to prevent the left and right displacements and front and back movement of the wire harness, so that the wire harness is fixed and stable, and has the advantages of low production cost and convenient assembly, etc.; the upper end and the hook head of the clamping head hook are both arranged in an arc shape, which can take into account both the smooth feeding of the wire harness and the prevention of damage to the wire harness.

[0014] The following is a further description with reference to the accompanying drawings.

[0015] Figure 1-3 As shown: a wiring harness fixing structure, including left and right clamps 3 and 4 that are stamped and formed by the opening 2 of the frame panel 1 and symmetrically clamp the wiring harness. The left and right clamps 3 and 4 are tilted and gathered from bottom to top toward the middle. The left and right clamps 3 and 4 both include a clamp body 5 and a clamp hook 7. The lower end of the clamp body 5 is connected to the 2 sides of the opening of the frame panel 1, and the inner wall of the clamp body 5 is glued with a rubber pad 6. The clamp body 5 is connected to the clamp hook 7. The outer opening of the clamp hook 7 is set as a closing surface 8 that is inclined inward from top to bottom. The clamp hook under the closing surface 8 is a hook head 9 structure, and the upper end of the clamp hook and the hook head 9 are arc structures. In this embodiment, a plurality of openings 2 are spaced apart on the frame panel 1, and the left and right clamps 3 and 4 are stamped upward from the openings 2 to complete the clamping and fixing of the wiring harness 10.

[0016] Based on this embodiment, it is preferred that the distance between the hooks of the left and right clamps is smaller than 1 mm of the wire harness diameter.

[0017] Based on this embodiment, it is preferred that the distance between the rubber pads on the clamp bodies of the left and right clamps is greater than 2 mm of the wire harness diameter.

[0018] Based on this embodiment, the inner surface of the rubber pad may be rolled with patterns or provided with anti-skid edges or frosted to further improve the fixing stability of the wire harness.
