Description

Technical Field

[0001] The utility model relates to the field of fixing a vehicle lamp harness, in particular to an installation and fixing structure of a vehicle lamp harness. Background Art

[0002] In the prior art, the headlight harness buckles are all integrally injection molded with plastic parts. However, in the current buckles, the hooks of most buckles are inverted in the direction of demolding, and the slider core needs to be pulled out of the mold. Figure 2 This will increase the mold structure and development costs. Some wiring harness buckles are molded through and molded by local adjustment, such as Figure 1 , which requires opening a hole at the plastic buckle, so this solution cannot be applied to the outer shell with sealing requirements, and can only be used on internal parts, so it has limitations and is not beautiful. With the richness and diversification of car light functions and lighting effects, the use of car light wiring harnesses is also increasing. The traditional wiring harness fixing solution has great limitations. Considering factors such as space, location, and cost, it is urgent to design a new type of car light wiring harness buckle to solve the above problems. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an installation and fixing structure for automobile lamp wiring harness, which does not require a slider or a hole, is not restricted in the use position, can adopt a strong demoulding method, and reduces the complexity of the mold.

[0004] In order to solve the above technical problems, the technical solution of the utility model is:

[0005] A mounting and fixing structure for a vehicle lamp harness, comprising a plastic body, a limiting rib and a clamping rib arranged on the plastic body, wherein the inner side surface of the limiting rib close to the clamping rib is a plane, and the inner side surface of the clamping rib close to the limiting rib is an S-shaped curved surface;

[0006] The clamping rib comprises a clamping portion at the root and an arc-shaped anti-slip portion at the head, and the distance between the clamping portion and the limiting rib is greater than the minimum distance between the arc-shaped anti-slip portion and the limiting rib.

[0007] Furthermore, a guide angle is provided at the head of the limiting rib.

[0008] Furthermore, the arc-shaped anti-slip portion gradually approaches the limiting rib from both ends to the middle.

[0009] Furthermore, the width of the limiting rib is smaller than that of the clamping rib.

[0010] Furthermore, the material of the limiting ribs and the clamping ribs is PP or PC or ABS or PC+ABS.

[0011] By adopting the above technical solution, the utility model has the following beneficial effects:

[0012] 1. The utility model adopts the method of limiting ribs and snap-in ribs buckling, which is different from the traditional structure. No holes are required at the buckles. On the one hand, it is more beautiful, and on the other hand, no slider is required. The use position is not restricted and can be used on any part.

[0013] 2. The utility model has a simple structure. The buckle is formed by the clamping ribs and limiting ribs made of elastic material. The arc-shaped anti-detachment part further prevents the wiring harness from falling off. There is no need for a slider core-pulling structure. Strong demoulding can be achieved and the overall performance of the buckle can be guaranteed. The mold structure is reduced, the complexity of the mold is reduced, and it plays a great role in reducing costs.

[0014] 3. The buckle of the utility model does not need a bayonet, and a self-adaptive buckle is formed by a special shape of the clamping ribs and the limiting ribs. It is not affected by the installation parts, is more beautiful, and has good practicality.

[0015] 4. The utility model adopts the guide angle of the limiting rib head and the design of the arc-shaped anti-slip portion of the clamping rib head, so that the clamping rib as a whole also presents an S shape, which is convenient for workers to install and operate, and the overall assembly process is simple and quick.

[0022] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0023] In the traditional structure, the hook of the headlight harness buckle is inverted in the direction of demolding, and the slider core must be pulled out to demold.Figure 2 The slider core-pulling structure 9 will increase the mold structure and development cost. In addition, some wire harness clips use the mold punching-out and parting-out methods through local adjustment. Refer to Figure 1 the punching-out structure 8, which requires opening holes at the plastic part clips, making this solution inapplicable to the outer shell with sealing requirements and can only be used for internal parts, having limitations and being not aesthetically pleasing.

[0024] Therefore, as Figures 3 - 5 shown, in this embodiment, an installation and fixing structure for an automotive headlight wire harness is provided, which mainly consists of a plastic part body 1 and the limiting ribs 2 and clamping ribs 3 formed thereon. The materials of the limiting ribs 2 and clamping ribs 3 can be selected from common materials for headlights such as PP, PC, ABS, or PC+ABS.

[0025] Specifically, the inner side of the limiting rib 2 close to the clamping rib 3 is a plane, and the inner side of the clamping rib 3 close to the limiting rib 2 is an S-shaped curved surface. The clamping rib 3 is specifically composed of a clamping part 31 at the root and an arc-shaped anti-detachment part 30 at the head, and the distance from the clamping part 31 to the limiting rib 2 is greater than the minimum distance from the arc-shaped anti-detachment part 30 to the limiting rib 2. Refer to Figure 5 shown, that is, the distance C is greater than the distance A. The minimum distance A exists at the middle position of the arc-shaped anti-detachment part 30, and the arc-shaped anti-detachment part 30 gradually approaches the limiting rib 2 from both ends to the middle. The minimum distance A is less than the diameter B of the wire harness 4. The wire harness 4 slides through the elastic arc-shaped anti-detachment part 30 and enters the clamping part 31 to complete the clamping. The clamping part 31 plays a limiting role, and the arc-shaped anti-detachment part 30 can prevent the wire harness 4 from falling off.

[0026] To facilitate the installation and insertion of the wire harness 4, a guiding angle 20 is provided at the head of the limiting rib 2 in this embodiment. Coupled with the arc design of the arc-shaped anti-detachment part 30, it is very easy to insert the wire harness 4, which has the function of guiding installation. In addition, the width of the limiting rib 2 in this embodiment is smaller than that of the clamping rib 3, and the design of one narrow and one wide can also facilitate the insertion of the wire harness 4.

[0027] Through the above design, it can be seen that the structure of this embodiment is different from the traditional structure. There is no need to open holes at the clip, which is more aesthetically pleasing on the one hand and does not require a slider on the other hand. The usage position is not restricted and can be used on any part. The structure of this embodiment is simple. The clamping rib 3 and the limiting rib 2 made of elastic materials form a clip. The arc-shaped anti-detachment part 30 further prevents the wire harness from falling off. There is no need for a slider core-pulling structure, and strong demolding can be achieved while ensuring the overall performance of the clip, reducing the mold structure and the complexity of the mold, which plays a great role in cost reduction. At the same time, the clip of this embodiment does not require a bayonet. The clip that can be self-adaptively clamped is formed by the clamping rib 3 and the limiting rib 2 with special shapes, which is not affected by the installation part, is more aesthetically pleasing, and has good practicability.
