Description

Technical Field

[0001] This utility model relates to the field of sealing gasket technology, and more specifically, to a connector sealing gasket. Background Technology

[0002] Automotive electrical components have stringent requirements for sealing and insulation, typically employing connector gaskets at their connection ports. Traditional gaskets usually feature open sealing holes for cables and terminals to pass through. However, in practice, some sealing holes may not be needed, necessitating the addition of plugs to seal these unused blind holes. Furthermore, during demolding, the lower mold pins, designed with blind holes, are prone to pulling the product along with them, hindering demolding. Since the lower mold is subsequently used for molding other products, product adhesion can impact subsequent processes, affecting production efficiency and product quality. To ensure the product remains fixed to the mold's center plate after demolding and can be moved with the center plate by operators, a connector gasket that solves the problem of product adhesion to the lower mold is required. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned defects in the prior art and provide a connector sealing gasket that can solve the problem of products sticking to the mold, so that the sealing gasket body is fixed on the mold plate and the demolding efficiency is improved.

[0004] To achieve the above objectives, this utility model provides a connector sealing gasket, including a sealing gasket body. The outer edge of the sealing gasket body is provided with a side sealing rib for sealing connection with the connector housing through an interference fit. The front of the sealing gasket body is provided with a plurality of sealing blind holes with open tops and closed bottoms. The inner bottom of each sealing blind hole forms a thin-walled structure between the inner bottom of the sealing blind hole and the outer wall of the sealing gasket body, which is easily pierced by the connector terminal or cable. The back of the sealing gasket body is provided with a stepped blind hole with open tops and closed bottoms. Each stepped blind hole and each sealing blind hole are staggered on the front and back of the sealing gasket body, respectively.

[0005] Preferably, the depth of the stepped blind hole is less than the depth of the sealed blind hole, and the opening diameter of the stepped blind hole is less than the opening diameter of the sealed blind hole.

[0006] Preferably, each sealed blind hole includes an inlet section, a first bottleneck section, a buffer section, a second bottleneck section, and a sealing section connected in sequence. The inlet section is bowl-shaped and recessed inward. The first bottleneck section and the second bottleneck section have the same diameter. Both the first bottleneck section and the second bottleneck section are configured as convex ring structures for sealing with the connector cable through an interference fit.

[0007] Preferably, the longitudinal cross-sectional shape of each step blind hole is set in an "I" shape.

[0008] Preferably, a plurality of anti-sticking particles are evenly distributed on both sides of the sealing gasket body, and the anti-sticking particles are arranged in a hemispherical structure.

[0009] Preferably, both sides of each side sealing rib are designed with an arc-shaped transition.

[0010] Preferably, the sealing gasket body is configured as a polygonal flat structure, and the outer edges of the sealing gasket body are provided with rounded corner transitions.

[0011] Preferably, the sealing gasket body is made of rubber.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The present invention has a simple structure and reasonable design. The outer edge of the sealing gasket body is provided with side sealing ribs. Several sealing blind holes are opened on the front of the sealing gasket body and stepped blind holes are opened on its back. In the demolding process, the present invention achieves the function of dispersing demolding stress and positioning by adding stepped blind holes and side sealing ribs, which solves the problem of product sticking to the mold.

[0014] 2. When the cables and terminals of the automotive connector are inserted into the sealing blind hole, the thin-walled structure of this utility model allows the terminals or cables to easily pierce through the thin-walled structure to complete the assembly. For unused sealing blind holes, the blind hole structure remains intact and has sealing performance. In practical applications, no additional plug parts are needed to block the sealing blind holes, simplifying the assembly cost of the connector and the sealing gasket. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Please refer to Figure 1 The present invention provides a connector sealing gasket, including a sealing gasket body 1. The components of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] like Figure 1 and Figure 2As shown, the sealing gasket body 1 can be configured as a polygonal flat structure, and the outer edges of the sealing gasket body 1 are provided with rounded corner transitions.

[0030] Preferably, the outer edge of the sealing gasket body 1 may be provided with a side sealing rib 2 for sealing connection with the connector housing by interference fit.

[0031] In this embodiment, the front side of the sealing gasket body 1 may have several sealing blind holes 3 with open tops and closed bottoms. The bottom of each sealing blind hole 3 forms a thin-walled structure between its inner bottom and the outer wall of the sealing gasket body 1, which is easily pierced by the connector's terminal or cable. By designing the thin-walled structure, cables or terminals can be easily pierced without affecting the overall sealing performance.

[0032] Furthermore, the back of the sealing gasket body 1 may be provided with a stepped blind hole 4 that is open at the top and closed at the bottom, and each stepped blind hole 4 and each sealing blind hole 3 are staggered on the front and back surfaces of the sealing gasket body 1.

[0033] In this embodiment, three side sealing ribs 2 are preferably provided, and the sealing blind holes 3 are arranged in an array. Of course, in other embodiments, the number of side sealing ribs 2 and the arrangement of sealing blind holes 3 can be set according to their paired automotive connectors and are not limited. In addition, the number of stepped blind holes 4 is preferably four or more. In this embodiment, eight are preferably provided and their arrangement position is not limited.

[0034] Preferably, the sealing gasket body 1 can be made of rubber and has a certain elasticity. After being punctured by the terminal or cable of the automotive connector, the rubber at its edge will also wrap around the outer wall of the terminal or cable.

[0035] like Figure 3 and Figure 4 As shown, the depth of the stepped blind hole 4 can be less than the depth of the sealing blind hole 3, and the opening diameter of the stepped blind hole 4 is less than the opening diameter of the sealing blind hole 3. The opening diameter of the sealing blind hole 3 can be designed to be larger than the opening diameter of the stepped blind hole 4, depending on the actual needs of different cables on the automotive connector.

[0036] In this embodiment, each sealed blind hole 3 may include an inlet section 31, a first bottleneck section 32, a buffer section 33, a second bottleneck section 34 and a sealing section 35 connected in sequence. The inlet section 31 is bowl-shaped and recessed inward. The first bottleneck section 32 and the second bottleneck section 34 have the same diameter. The first bottleneck section 32 and the second bottleneck section 34 are both configured as convex ring structures for sealing connection with the cable of the connector through an interference fit.

[0037] Preferably, the inlet section of the sealed blind hole 3, which has a bowl-shaped structure, can guide the cable insertion end to be inserted and play a guiding role; the first bottleneck section 32 and the second bottleneck section 34 can be symmetrically arranged, and the cross-section of their convex ring structure is arc-shaped.

[0038] Of course, in other embodiments, there may be two or more bottleneck sections depending on the cable arrangement of the connector. In this embodiment, the number of bottleneck sections is not limited.

[0039] In the automotive connector, after the cable passes through the sealed blind hole 3, the outer wall of the cable can be tightly wrapped by the internal convex ring structure. This convex ring structure not only ensures the sealing performance but also improves the stability of the assembly, playing a waterproof sealing role. Its structure is compact and has a good sealing effect.

[0040] like Figures 6 to 8 As shown, the longitudinal cross-sectional shape of each step blind hole 4 can be set in an "I" shape.

[0041] Furthermore, a number of anti-sticking particles 6 can be evenly distributed on both sides of the sealing gasket body 1, and the anti-sticking particles 6 are arranged in a hemispherical structure. The anti-sticking particles 6 can prevent the sealing rings on the automotive connector from sticking to each other or to the conveying equipment, making assembly difficult.

[0042] In practice, the automotive connector cable is inserted into the opening of the sealing blind hole 3 of the sealing gasket body 1, and pierces the thin-walled structure on the other side of the sealing gasket body 1. The convex ring structure in the pierced sealing blind hole 3 tightly wraps around the outer wall of the automotive connector cable, achieving a good sealing effect on the automotive connector cable. At the same time, the blind hole structure of the remaining unused sealing blind hole 3 remains intact and has sealing performance. Finally, the side sealing rib 2 of the sealing gasket body 1 is press-fitted with the automotive connector shell to achieve a sealed connection, thus completing the assembly.

[0043] like Figures 9 to 11 As shown, during the production process, the sealing gasket body 1 is located inside the middle plate 12 of the mold, and the upper plate 11 and the lower plate 13 of the mold close from the upper and lower sides to press and form the sealing gasket body 1.

[0044] In traditional molds with blind hole designs, the lower mold, due to its blind hole sealing pin structure, often causes the mold pins on the lower mold plate 12 to pull the sealing gasket down with it, resulting in the product sticking to the lower mold. To keep the sealing gasket body 1 on the mold plate 12 and avoid this situation, this embodiment has at least four stepped blind holes 4 and at least three side sealing ribs 2 formed on the back of the sealing gasket body 1. The stepped blind holes 4 provide additional fixing points during demolding, effectively dispersing the demolding stress applied to the product by the lower mold. At the same time, the side sealing ribs 2 enhance the edge stability of the sealing gasket body 1, ensuring that the product will not move or fall off due to the downward movement of the lower mold. This design allows the product to be fixed on the mold plate 12, improving product quality and demolding stability.

[0045] In summary, this utility model, by adding stepped blind holes and side sealing ribs during the demolding process, achieves the functions of dispersing demolding stress and positioning, solving the problem of products sticking to the mold. This allows the sealing gasket body to be fixed on the mold plate, making it convenient for workers to transfer the product together with the mold plate, thus improving the demolding efficiency and ease of operation.

[0046] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
