Description

Technical field:

[0001] The utility model relates to the technical field of automobile accessories, in particular to a sealing rubber plug structure for automobile lamp harness. Background technology:

[0002] With the development of science and technology and the improvement of people's quality of life, car styling has become more diverse and lamps have become more and more refined. Car lamps have become an indispensable focus of car styling.

[0003] The lighting of the lamp requires wiring from the external car control end to the lamp board end inside the lamp. The use of electronic connectors can reduce the time of manual wire welding and avoid the risk of poor welding. Some automotive lamps require flat and thin strips, which results in very small Z-direction space for the product, making it impossible to arrange the commonly used wire harness sealing plugs, making installation difficult, time-consuming and labor-intensive.

[0004] The Chinese utility model patent with patent number 201921023532.1 discloses a hollow silicone plug tube, which is made of elastic silicone material or rubber material; the hollow silicone plug tube is in the shape of a long tube, with an axial hollow hole in the middle, and two circles of limiting convex rings are arranged on the middle outer wall, and a concave ring-type buckle section is between the two circles of limiting convex rings. The hollow silicone plug tube is inserted into the wire entry hole, one of the limiting convex rings is arranged at the hole opening of the inner wall of the wire entry hole, and the other limiting convex ring is arranged at the hole opening of the outer wall of the wire entry hole, the concave ring-type buckle section is expansion-tightened on the wire entry hole body, and the limiting convex rings at the inner and outer openings clamp the inner and outer edges of the wire entry hole to seal the hole body; the concave ring-type buckle section on the outer wall of the hollow silicone plug tube is tightly and fixedly connected to the wire entry hole by extrusion.

[0005] The hollow silicone plug tube has the above-mentioned technical problems: since the two circles of limiting convex rings correspond to the internal axial hollow hole, and the axial hollow hole is used to pass the wires and seal the contact, the two circles of limiting convex rings do not have much avoidance space to form elastic deformation, and can only deform through the characteristics of their own materials. As a result, when the hollow silicone plug tube is inserted into the wire entry hole, the front circle of limiting convex rings in the insertion direction is difficult to directly pass through the wire entry hole and extend out of the wire entry hole, so that the two circles of limiting convex rings are respectively buckled outside the ports on both sides of the wire entry hole, which makes installation difficult, time-consuming and labor-intensive, causing great trouble to users.

[0006] In view of this, the inventor proposes the following technical solution. Utility model content:

[0027] The utility model is further described below in conjunction with specific embodiments and drawings.

[0028] See Figure 1-8 As shown, a sealing rubber plug structure for wiring harness of automobile lamps includes a sealing rubber plug 1 which is fixed to the mounting hole 21 of the lamp body 2 and can produce elastic deformation. The sealing rubber plug 1 is formed with a groove 11 and a front buckle body 12 and a rear buckle body 13 respectively located at the front and rear ends of the groove 11. The sealing rubber plug 1 is provided with a through wire hole 10 for the wiring harness 3 to pass through along its front end surface. The characteristics are as follows:

[0029] The sealing rubber plug 1 is provided with a hollow groove 14 along its front end surface to enable the front buckle body 12 to be deformed from outside to inside, and the hollow groove 14 is distributed correspondingly to the inside and outside of the front buckle body 12 .

[0030] When the utility model is used, the wire harness 3 is passed through the wire hole 10 of the sealing rubber plug 1 to form a sealed contact therebetween, and then the sealing rubber plug 1 is installed into the mounting hole 21 of the lamp body 2. At this time, since the sealing rubber plug 1 is provided with a hollow groove 14 along its front end surface to enable the front buckle body 12 to be concave and deformed from the outside to the inside, the front buckle body 12 part of the front end of the sealing rubber plug 1 can be directly squeezed to make the inner side of the front buckle body 12 concave and deformed toward the hollow groove 14, thereby greatly reducing the size of the front buckle body 12 part of the front end of the sealing rubber plug 1. The front buckle body 12 of the sealing plug 1 can smoothly pass through the wire hole 10 of the sealing plug 1, and the wire hole 10 will be squeezed and contact the wire more closely. Then, the front buckle body 12 of the sealing plug 1 will automatically reset, and then buckle against the inside of the lamp body, and cooperate with the rear buckle body 13 to clamp at the front and rear ports of the mounting hole 21 of the lamp body 2. It is extremely simple and easy to assemble, and it can ensure that the sealing plug 1 is stably installed at the mounting hole 21 of the lamp body 2, and it is not easy to fall off, ensuring the stability of the assembly structure, and at the same time ensuring airtightness and waterproof performance. In other words, the utility model has a reasonable structural design of the wiring harness sealing plug of the automobile lamp. After the wiring harness is installed into the sealing plug, it is assembled with the lamp body, occupies a small space, is easy to assemble, has a stable and reliable seal, and the sealing plug is not easy to fall off, which solves the problem of complex installation and easy falling off of the wiring harness sealing plug of flat and long lamps and small automobile lamps, thereby improving the quality of the lamp.

[0031] In order to further improve the airtightness of the sealing plug 1 and the mounting hole 21, the following design is also made: a plurality of sealing ribs 111 are also provided in the groove 11, and the sealing ribs 111 are in contact with the inner wall of the mounting hole 21 of the lamp body 2 to achieve sealing contact, thereby further improving the airtightness of the sealing plug 1 and the mounting hole 21. In this embodiment, there are three sealing ribs 111, and the assembly airtightness is better. Among them, the outer diameter of the sealing rib 111 is larger than the inner diameter of the mounting hole 21, so that the sealing rib 111 and the inner wall of the mounting hole 21 form an interference fit assembly, thereby enhancing the sealing performance therebetween.

[0032] The opening size of the hollow groove 14 is larger than the bottom size, and the inner wall of the hollow groove 14 is an inclined surface, so that the front buckle body 12 corresponding to the hollow groove 14 can better realize the concave deformation, which can improve the assembly efficiency and make the assembly smoother and easier.

[0033] The front end periphery of the front buckle body 12 is formed with an inclined guide surface 121, and the inclined guide surface 121 has a good guiding effect, so that the front buckle body 12 can pass through the mounting hole 21 of the lamp body 2 more easily, thereby improving the assembly efficiency and making the assembly smoother and easier.

[0034] The wire hole 10 is also connected to the hollow groove 14, so that passing the wire harness through the wire hole 10 is easier and more efficient.

[0035] The rear end of the wire hole 10 is provided with a wire entry opening 101 in the shape of a trumpet which is large outside and small inside. The wire entry opening 101 has a good guiding effect, so that the wire harness passes through the wire hole 10 more easily and efficiently.

[0036] The inner walls of the groove 11 are vertical surfaces, and the width of the groove 11 is larger than the axial dimension of the mounting hole 21, wherein the width of the groove 11 is 0.5 mm larger than the axial dimension of the mounting hole 21, so that after the sealing plug 1 is installed in the mounting hole 21 of the lamp body 2, a gap is formed between the inner wall of the groove 11 and the end face of the lamp body 2. When installing the sealing plug, the pushing amount will be increased by 0.5 mm to ensure that the front buckle body 12 can completely enter the interior of the lamp body and unfold, and ensure that it is completely pushed into place during installation, and at the same time, it can also prevent the sealing plug from falling off.

[0037] The sealing rubber plug 1 is integrally formed of elastic silicone material or rubber material.

[0038] The sealing rubber plug 1 is a semi-hollow rectangular parallelepiped structure.

[0039] To sum up, the utility model has a reasonable structural design of the wiring harness sealing plug of the automobile lamp. After the wiring harness is installed into the sealing plug, it is assembled with the lamp body. It occupies a small space, is easy to assemble, has a stable and reliable seal, and the sealing plug is not easy to fall off. It solves the problem of complicated installation and easy falling off of the wiring harness sealing plug of flat and long lamps and small automobile lamps, thereby improving the quality of the lamp.
