[0028] Embodiment

[0029] The embodiment provides a waterproof structure of an automobile connector, which comprises a sleeving body 1 and a waterproof rubber ring 2 located outside the sleeving body 1, and at least one positioning extension block 3 provided on the sleeving body 1 and connected with the automobile connector.

[0030] The specific improvement is that, as shown in Figures 1-3 , compared with the prior art, the waterproof rubber ring 2 is sleeved on the sleeving body 1 to form an assembly, then the assembly is sleeved on the connecting part of the automobile connector, and the protruding block on the automobile connector is inserted into the positioning extension block 3 to form fixation. Since the sleeving body 1 is made of plastic and has higher hardness than the waterproof rubber ring 2, the waterproof rubber ring 2 is clamped between the sleeving body 1 and the automobile connector. Since the protruding block on the automobile connector is in the connecting state with the positioning extension block 3 on the sleeving body 1, the waterproof rubber ring 2 will not be taken off in the process of plugging and unplugging the automobile connector, so that the movement of the waterproof rubber ring 2 in the process of plugging and unplugging is avoided, and the waterproof effect is reduced. In the embodiment, the automobile connector is the prior art, and the structure of the automobile connector will not be described any more.

[0031] On the basis of the above embodiment, the sleeving body 1 comprises a first sleeving ring 11 and a second sleeving ring 12 arranged outside the first sleeving ring 11, and an avoiding cavity 4 is formed in the first sleeving ring 11.

[0032] The specific improvement is that, as shown in Figure 3 and Figure 6 , the sleeving body 1 comprises the first sleeving ring 11 and the second sleeving ring 12 arranged outside the first sleeving ring 11, the first sleeving ring 11 forms an avoiding cavity 4, the waterproof rubber ring 2 is inserted into the first sleeving ring 11 and wraps the inner side and the outer side of the first sleeving ring 11, in the installation process, the outer side of the automobile connector is attached to the inner side of the waterproof rubber ring 2, and the inner side of the waterproof rubber ring 2 is provided in a corrugated structure, the corrugated extension part is connected with the outer side of the automobile connector, so that the waterproof effect is better.

[0033] On the basis of the above embodiment, the waterproof rubber ring 2 comprises a waterproof body 21 and a waterproof extension part 22 wrapped on the inner side wall of the second sleeving ring 12, the waterproof body 21 is provided with an annular groove 23 for inserting the first sleeving ring 11, and the waterproof body 21 is further provided with a through groove 24 for the positioning extension block 3.

[0034] The specific improvement is that, as shown in Figure 4 and Figure 7As shown, the waterproof rubber ring 2 includes a waterproof body 21 and a waterproof extension 22 wrapped around the inner wall of the second sleeve ring 12. The first sleeve ring 11 is inserted into the waterproof rubber ring 2, and the combination of the two not only ensures the hardness of the waterproof rubber ring 2, but also ensures that the waterproof rubber ring 2 can be wrapped around the outside of the automobile connector, thereby forming a waterproof structure at the connection. In addition, the positioning extension block 3 passes through the through slot 24 on the waterproof body 21, so that the sleeve body 1 and the waterproof rubber ring 2 are tightly fitted, and when the waterproof rubber ring 2 is installed to the outside of the automobile connector, it can be ensured that the waterproof rubber ring 2 is clamped between the automobile connector and the sleeve body 1. Therefore, when disassembling, the waterproof rubber ring 2 will not be deformed due to the insertion of the first sleeve ring 11 to improve the support strength, and when installing, after the waterproof rubber ring 2 is sleeved on the outside of the automobile connector, the protrusion of the automobile connector will be inserted into the positioning extension block 3, so that the two are connected and the connection strength between the two is increased.

[0035] Based on the above embodiment: the second sleeve ring 12 includes an outer ring sleeve 13 located on the outer wall of the first sleeve ring 11 and an inner ring sleeve 14 located on the inner wall of the first sleeve ring 11, and the waterproof extension 22 is wrapped around the outer end of the inner ring sleeve 14.

[0036] The specific improvement is that, as shown in Figure 3 and Figure 4 As shown, the second sleeve ring includes an outer ring sleeve 13 and an inner ring sleeve 14 located on the inner and outer sides of the first sleeve ring 11, respectively. The first sleeve ring 11 is inserted into the waterproof body 21, and the outer end face portion is in contact with the outer ring sleeve 13, and the inner end face portion completely wraps the inner ring sleeve 14. Since the inner wall of the waterproof body 21 is in contact with the outer wall of the automobile connector, in order to prevent gaps between the two connections, the waterproof extension 22 on the waterproof rubber ring 2 is wrapped around the inner ring sleeve 14 to prevent the inner ring sleeve 14 from contacting the automobile connector. At the same time, through the arrangement of the waterproof extension 22, the sealing between the waterproof rubber ring 2 and the automobile connector can be effectively increased, thereby improving the waterproof performance.

[0037] Based on the above embodiment: the inner ring sleeve 14 is provided with a bending arc surface 5, and the waterproof rubber ring 2 is also provided with a sealing extension ring 6 in contact with the bending arc surface 5.

[0038] The specific improvement is that, as shown in Figure 3 Through the arrangement of the extension sealing and the bending arc surface 5, the inner sleeve can be better wrapped, and through the arrangement of the inner ring sleeve 14, the contact area of the sleeve body 1 and the waterproof rubber ring 2 can be increased, so that the two are more tightly fitted.

[0039] On the basis of the above embodiment: the waterproof extension 22 is provided with a wrapping groove 7 wrapped outside the inner ring sleeve 14 on the side opposite to the inner ring sleeve 14.

[0040] The specific improvement is that, as shown in Figure 7 , the inner ring sleeve 14 is embedded in the wrapping groove 7, and then the waterproof extension 22 is included outside the inner ring sleeve 14, thereby increasing the contact area of the sleeve body 1 and the waterproof sealing ring and the connection tightness.

[0041] On the basis of the above embodiment: the positioning extension block 3 is provided with two, the positioning extension block 3 is provided with a plug slot 8 connected with the automobile connector, and the positioning extension block 3 and the first sleeve ring 11 are further provided with a filling groove 9 for inserting the waterproof rubber ring 2.

[0042] The specific improvement is that, as shown in Figure 5 and Figure 6 , the positioning extension block 3 is provided with a plug slot 8 for the protrusion on the automobile connector to pass through, and the positioning extension block 3 and the first sleeve ring 11 are further provided with a filling groove 9 for inserting the waterproof rubber ring 2, thereby increasing the contact area between the sleeve body 1 and the waterproof rubber ring 2 and providing a barrier for water entering the automobile connector and increasing the difficulty of water entering.

[0043] Obviously, the above embodiment is only an example for clearly illustrating, and does not limit the implementation. For ordinary skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, all the implementations do not need to be exhausted, and the obvious changes or variations derived therefrom are still within the protection scope of the present application.
