Description

Technical Field

[0001] This application relates to the field of automotive headlight sealing technology, and specifically discloses a rubber plug structure for sealing automotive headlights. Background Technology

[0002] The rubber plugs used in automotive headlights are mainly wiring harness plugs, structures used to fix wiring harnesses and provide a certain degree of sealing. Due to the market environment, current automotive headlights are developing towards through-type, integrated, and slender structures, resulting in an increasing number of wiring harnesses required for headlights. Conventional automotive headlight plugs are clearly less suitable. Therefore, structural improvements are needed for automotive headlight plugs to cope with the changes in current automotive headlights. In view of this, this utility model provides a sealing rubber plug structure for automotive headlights to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to solve the problem that traditional automotive headlight plugs cannot secure multiple wire harnesses.

[0004] To achieve the above objectives, this utility model provides the following basic solution:

[0005] A rubber plug structure for sealing automotive headlights includes a rubber plug body detachably connected to the headlight housing for fixing multiple wire harnesses or / and a single wire harness, a slot structure integrally formed with the bottom of the rubber plug body for engaging with the headlight housing, a plurality of wire harness holes through the rubber plug body for placing multiple wire harnesses or / and a single wire harness, a rubber groove based on the wire harness holes, and male and female bosses disposed within the wire harness holes.

[0006] Furthermore, the slot structure includes an upper end face near the rubber stopper body, a lower end face away from the rubber stopper body, and a slot gap between the upper end face and the lower end face. The slot gap engages with the lamp housing. The upper end face is an inclined upper end face. The side of the inclined upper end face near the center line of the rubber stopper body is the high point position, and the side of the inclined upper end face away from the center line of the stopper body is the low point position.

[0007] Furthermore, the wire harness hole penetrates the rubber plug body and the slot structure, one end of the multi-wire harness or / and single-wire harness protrudes from the rubber slot, and the other end of the multi-wire harness or / and single-wire harness protrudes from the bottom of the slot structure.

[0008] Furthermore, the adhesive groove is fixed to the wire harness hole and is concentric with the wire harness hole. The inner wall of the adhesive groove is a gradient inner wall, and the inner diameter of the gradient inner wall gradually decreases along the inner bottom of the adhesive groove.

[0009] Furthermore, it also includes a sealing gasket, which is installed on the outer periphery of the rubber plug body after the rubber plug body is snapped into the lamp housing.

[0010] Furthermore, the male and female bosses include a female boss and a male boss, which are arranged vertically through the wire harness hole.

[0011] Furthermore, the inner diameter of the female boss is smaller than the inner diameter of the male boss.

[0012] The principle and effect of this solution are as follows:

[0013] 1. Compared with the prior art, the present invention has a slot structure. The rubber plug body is usually a solid structure, and the connection with the lamp housing is usually a planar connection, that is, both connection surfaces are planar. This makes it very difficult for the operator to connect in actual operation. Therefore, the present invention has a slot structure, which directly improves this problem and makes it easy and effortless to connect the present invention with the lamp housing.

[0014] 2. Compared with the prior art, the present invention has male and female bosses, which are set in the wire harness hole, making the rubber plug body suitable for more types of multi-wire harnesses and / or single wire harnesses.

[0015] 3. Compared with the existing technology, a glue groove is set. The glue groove based on the wire harness hole is equivalent to the external extension of the wire harness hole, which can facilitate glue application to the wire harness hole and better ensure the connection stability and sealing performance between the glue plug body and the wire harness.

[0021] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0022] The reference numerals in the accompanying drawings include: 1. sealing gasket; 2. lamp housing; 3. wiring harness; 4. rubber plug body; 5. slot structure; 6. slot gap; 7. upper end face; 8. lower end face; 9. rubber groove; 10. gradient inner wall; 11. female boss; 12. male boss.

[0023] Implementation, for example Figures 1-4 As shown:

[0024] A rubber plug structure for sealing automotive headlights includes a rubber plug body 4 detachably connected to a headlight housing 2 for fixing multiple wire harnesses 3 or / and a single wire harness 3, a slot structure 5 integrally formed with the bottom of the rubber plug body 4 for engaging with the headlight housing 2, a plurality of wire harness 3 holes through the rubber plug body 4 for placing multiple wire harnesses 3 or / and a single wire harness 3, a rubber groove 9 based on the wire harness 3 holes, and male and female bosses 12 disposed in the wire harness 3 holes.

[0025] This structure is used in conjunction with the lamp housing 2. After the rubber plug body 4 is engaged, it also includes a sealing gasket 1. The sealing gasket 1 is installed on the outer periphery of the rubber plug body 4 to improve the sealing effect after the structure is engaged with the lamp housing 2.

[0026] Regarding slot structure 5: Slot structure 5 is used to engage with lamp housing 2.

[0027] like Figure 2 , Figure 4 As shown:

[0028] The slot structure 5 includes an upper end face 7 located near the rubber stopper body 4, a lower end face 8 located away from the rubber stopper body 4, and a slot gap 6 located between the upper end face 7 and the lower end face 8. The slot gap 6 is engaged with the lamp housing 2. The upper end face 7 is an inclined upper end face 7. The side of the inclined upper end face 7 that is closer to the center line of the rubber stopper body 4 is the high point position, and the side of the inclined upper end face 7 that is away from the center line of the stopper body is the low point position.

[0029] The lamp housing 2 is engaged with the slot gap 6. In traditional lamp housing 2 and slot gap 6, the engagement is a planar connection, that is, the upper end face 7 and the lower end face 8 are both planar. Since the rubber plug body 4 is a solid structure, the connection between the two is very difficult. In view of this, the upper end face 7 is improved to be an inclined upper end face 7. The lamp housing 2 and slot gap 6 are engaged by the inclination of the inclined upper end face 7, making the connection between the two easy and effortless.

[0030] Another feature of this structure is:

[0031] The wire harness 3 passes through the rubber plug body 4 and the slot structure 5. The upper end of the multi-wire harness 3 or / and the single-wire harness 3 exits from the rubber groove 9, and the other end of the multi-wire harness 3 or / and the single-wire harness 3 exits from the bottom of the slot structure 5. Regarding the rubber groove 9:

[0032] The glue groove 9 is fixed to the wire harness 3 hole and is concentric with the wire harness 3 hole. The inner wall of the glue groove 9 is a gradient inner wall 10. The inner diameter of the gradient inner wall 10 gradually decreases along the inner bottom of the glue groove 9. The glue groove 9 is set based on the wire harness 3 hole, which is equivalent to the external extension of the wire harness 3 hole. It can facilitate glue application to the wire harness 3 hole and better ensure the connection stability and sealing of the glue plug body 4 and the wire harness 3.

[0033] like Figure 4 As shown, the male and female bosses 12 include a female boss 11 and a male boss 12, which are arranged vertically through the hole of the wire harness 3. The inner diameter of the female boss 11 is smaller than the inner diameter of the male boss 12. This utility model is provided with male and female bosses 12, which are arranged in the hole of the wire harness 3, so that the rubber plug body 4 is suitable for more types of multi-wire harnesses 3 and / or single-wire harnesses 3. Because multi-wire harnesses 3 and / or single-wire harnesses 3 have compressible characteristics, the female boss 11 and male boss 12 can be used for wire harnesses 3 with different outer diameters, thus improving the applicability of this structure.

[0034] When using this utility model:

[0035] One end of the multi-wire harness 3 or / and the single-wire harness 3 is connected to the electronic components inside the vehicle body. Then the vehicle body is snapped into place with the rubber plug body 4. Then the other end of the multi-wire harness 3 or / and the single-wire harness 3 passes through the rubber groove 9. The multi-wire harness 3 or / and the single-wire harness 3 is fixed by applying glue through the rubber groove 9.

[0036] This structure solves the problem that traditional automotive headlight plugs cannot secure multiple wiring harnesses.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
