[0024] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Please refer to Figure 1 An embodiment of the utility model provides a connector sealing pad for preventing hole position deviation, including a sealing pad body 1. The various components of this embodiment are described in detail below in conjunction with the accompanying drawings.

[0026] like Figure 1As shown, the sealing gasket body 1 is configured as a flat structure, the shape of the sealing gasket body 1 can be configured as a polygonal structure, and the outer edges of the sealing gasket body 1 are configured as rounded transitions.

[0027] like Figure 3 As shown, the outer edge of the sealing gasket body 1 may be provided with at least three side sealing ribs 11 for achieving a sealed connection with the automobile connector housing by interference fit.

[0028] Preferably, the sealing gasket body 1 can be preferably configured to be made of rubber material.

[0029] like Figure 2 and Figure 4 As shown, at least three groups of seals 2 for inserting cables of different diameters are provided on the sealing gasket body 1, and each group of seals 2 is provided with a plurality of sealing holes 20. The aperture sizes of the sealing holes 20 corresponding to each group of seals 2 are different. Each sealing hole 20 is vertically arranged to penetrate the front and back sides of the sealing gasket body 1 and is evenly distributed on the sealing gasket body 1. The sealing holes 20 of this embodiment are not limited to one size.

[0030] Specifically, each sealing hole 20 is provided with at least two sealing protruding rings 201 arranged along the hole wall and used to achieve a sealed connection with the corresponding cables through interference compression fit.

[0031] Preferably, at least two sealing convex rings 201 can be symmetrically arranged, and the cross-section of each sealing convex ring 201 is arranged in an arc shape. After the cable of the automotive connector passes through the sealing hole 20, the outer wall of the cable can be tightly wrapped by the sealing convex ring 201 inside it, and the sealing convex ring 201 not only ensures the sealing performance but also improves the stability of the assembly.

[0032] The cross-sectional area of ​​each sealing hole 20 may gradually decrease and then increase from the top opening end to the bottom opening end. The top opening end and the bottom opening end of each sealing hole 20 are consistent in shape and size and are both arranged in a bowl-shaped structure.

[0033] The opening end of the sealing hole 20 in a bowl-shaped structure can guide the insertion end of the cable to be inserted and play a guiding role.

[0034] In this embodiment, a plurality of grooves 4 for relieving stress during cable assembly are respectively formed on the front and back surfaces of the sealing pad body 1 , and the grooves 4 are evenly distributed in the gaps between some of the sealing holes 20 .

[0035] Preferably, the shape of the groove 4 can be set to be square or circular, and this embodiment does not limit the shape of the groove 4.

[0036] In order to avoid damage and deformation of the sealing hole 20 due to uneven force during assembly, it is necessary to open a plurality of grooves 4 at a distance between the sealing holes 20. The sunken top of the groove 4 will form a new stress concentration point to share the original overly concentrated stress, thereby reducing and avoiding damage and deformation caused by the original overly concentrated stress. In this embodiment, 8 grooves 4 are respectively arranged, and the 8 grooves are respectively and correspondingly arranged on the front and back sides of the sealing pad body 1 in pairs. The grooves 4 can release the stress during the cable assembly process to reduce the assembly problems caused by the hole position offset after the cable assembly.

[0040] like Figure 8 As shown, the inner center of the third sealing hole 231 is provided with two third sealing protruding rings 232 arranged along the hole wall thereof and used to achieve a sealed connection with the cable of the automobile connector by interference fit.

[0041] The aperture of the first sealing hole 211 is larger than that of the second sealing hole 221 , and the aperture of the second sealing hole 221 is larger than that of the third sealing hole 231 , so that the automotive connector can be adapted to three cables with different wire diameters.

[0042] Furthermore, a plurality of anti-sticking particles 5 can be evenly dispersed on the front and back sides of the sealing pad body 1, and the anti-sticking particles 5 are arranged in a hemispherical structure. The anti-sticking particles 5 can prevent the sealing rings on the connector from adhering to each other or adhering to the conveying equipment, making it difficult to assemble.

[0043] During specific implementation, different cables on the automobile connector can be respectively inserted into different sealing holes 20 on the sealing gasket body 1, and the sealing convex ring 201 inside the sealing hole 20 passed through will tightly wrap the outer wall of the automobile connector cable, which can achieve a good sealing effect on the automobile connector cable. Then, the side sealing rib 2 of the sealing gasket body 1 is interference fit with the automobile connector shell to achieve a sealed connection, and the assembly is completed.

[0044] To summarize, the sealing gasket body of the utility model is provided with a plurality of sealing holes and grooves with different apertures and penetrating the sealing gasket body. When the sealing gasket body is used in conjunction with the automobile connector, different cables of the connector can pass through their corresponding sealing holes respectively. The sealing convex rings in the sealing holes can tightly wrap the outer walls of the cables to ensure the sealing effect. The assembly stability is good and the application range is wide. In addition, the design of the grooves can release the stress during the cable assembly process and can also reduce the assembly problems caused by the hole position offset after the cable assembly.

[0045] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments.
