[0029] like Figure 1-Figure 3As shown, according to the sealing structure of the embodiment of the present application, the sealing structure includes a cover body 1 and a waterproof rubber ring 2, a support portion 10 is provided on the cover body 1, a receiving cavity is provided in the waterproof rubber ring 2, the support portion 10 is arranged in the receiving cavity, and the inner side wall of the waterproof rubber ring 2 defines a wire hole for passing the cable.

[0030] Specifically, the sealing structure includes a cover body 1 and a waterproof rubber ring 2. The cover body 1 is provided with a support portion 10, and the support portion 10 is arranged in the accommodating cavity of the waterproof rubber ring 2. The support portion 10 is used to support the waterproof rubber ring 2 inside the waterproof rubber ring 2. When a cable is passed through the wire hole, if the cable is bent or tilted, the support portion 10 will drive the waterproof rubber ring 2 to adaptively shift synchronously with the cable, thereby alleviating the relative offset between the cable and the waterproof rubber ring 2. The unilateral offset or compression amount of the cable when squeezing the waterproof rubber ring 2 can be reduced, thereby avoiding or alleviating the irregular offset or compression of the waterproof rubber ring 2 by the cable as much as possible, thereby improving the sealing reliability of the waterproof rubber ring 2.

[0031] According to the sealing structure of the embodiment of the present application, while satisfying the compression elasticity of the cable, the support part 10 can be used to position the waterproof rubber ring 2 to limit the offset of the waterproof rubber ring 2 when the cable is bent and tilted, thereby ensuring the sealing between the waterproof rubber ring 2 and the cable, thereby improving the sealing reliability and avoiding failure.

[0032] In a specific embodiment, the support portion 10 includes a plurality of sub-frame portions, and the plurality of sub-frame portions are distributed at intervals along the circumference of the waterproof rubber ring 2 , so that the flexibility of the waterproof rubber ring 2 can be increased while the structural strength of the waterproof rubber ring 2 is increased.

[0033] like Figure 4 As shown, according to the sealing structure of the embodiment of the present application, the support portion 10 extends along the circumference of the wire hole.

[0034] In detail, the support portion 10 extends along the circumferential direction of the wire hole, so that the waterproof rubber ring 2 can be supported in the circumferential direction, the structural strength of the waterproof rubber ring 2 in the circumferential direction is increased, the deformation amount of the waterproof rubber ring 2 is controlled, and the unilateral offset or compression amount of the waterproof rubber ring 2 when the cable is squeezed in any direction can be reduced.

[0035] like Figure 3 and Figure 4 As shown, according to the sealing structure of the embodiment of the present application, a relief opening 11 is provided on the support portion 10 , and the waterproof rubber ring 2 fills the relief opening 11 .

[0036] Specifically, the support portion 10 is provided with an escape opening 11, and the waterproof rubber ring 2 fills the escape opening 11, which can increase the contact area between the waterproof rubber ring 2 and the support portion 10, thereby making the connection between the waterproof rubber ring 2 and the cover body 1 more firm and reliable.

[0037] The number of the avoidance openings 11 can be set as needed, for example, the number of the avoidance openings 11 is multiple, and the multiple avoidance openings 11 are arranged at intervals along the circumferential direction of the support portion 10. It can be understood that increasing the number of the avoidance openings 11 while ensuring the structural strength of the support portion 10 can further enhance the contact area between the support portion 10 and the waterproof rubber ring 2.

[0038] The shape of the avoidance opening 11 can be set as required. For example, the cross-sectional shape of the avoidance opening 11 is square, circular, triangular, elliptical, etc.

[0039] like Figure 1 , Figure 2 as well as Figure 4 As shown, according to the sealing structure of the embodiment of the present application, a stopper 20 is provided on the cover body 1 , and the stopper 20 and the support portion 10 together define a limiting groove 21 , and part of the waterproof rubber ring 2 is embedded in the limiting groove 21 .

[0040] In detail, a stopper 20 is provided on the cover body 1, and the stopper 20 and the support part 10 jointly define a limiting groove 21, and part of the waterproof rubber ring 2 is embedded in the limiting groove 21, so that the waterproof rubber ring 2 is in contact with the inner wall of the limiting groove 21 (at least part of the outer wall of the support part 10, at least part of the inner wall of the stopper 20 and the bottom wall of the limiting groove 21), thereby increasing the contact area between the waterproof rubber ring 2 and the cover body 1, and further improving the stability of the combination between the waterproof rubber ring 2 and the cover body 1.

[0041] In a specific embodiment, at least a portion of the outer side wall of the support portion 10 , the entire inner side wall of the stop portion 20 , and the bottom wall of the limiting groove 21 are in contact with the waterproof rubber ring 2 .

[0042] In some embodiments, the stopper portion 20 extends along the circumferential direction of the support portion 10 .

[0043] It is understandable that by providing the stopper 20 extending along the circumferential direction of the support portion 10 , the contact area between the stopper 20 and the support portion 10 can be increased as much as possible, thereby improving the stability of the connection between the waterproof rubber ring 2 and the cover body 1 .

[0044] like Figure 4 As shown, in some embodiments, the cover body 1 further includes a partition portion 30 , which is disposed in the limiting groove 21 , and two ends of the partition portion 30 are respectively connected to the stop portion 20 and the support portion 10 .

[0045] In detail, the cover body 1 also includes a partition 30, which is arranged in the limiting groove 21, and the two ends of the partition 30 are respectively connected to the stop portion 20 and the support portion 10, so that the waterproof rubber ring 2 contacts the two side walls of the partition 30, thereby increasing the contact area between the waterproof rubber ring 2 and the cover body 1, and improving the stability of the combination between the waterproof rubber ring 2 and the cover body 1.

[0046] like Figure 3 As shown, in some embodiments, the waterproof rubber ring 2 includes a rubber ring body 201, a first anti-slip portion 202 and a second anti-slip portion 203, the second anti-slip portion 203 defines a wire hole, and the diameter of the cable is larger than the diameter of the wire hole.

[0047] Specifically, the waterproof rubber ring 2 includes a rubber ring body 201, a first anti-slip portion 202 and a second anti-slip portion 203. The first anti-slip portion 202 can enhance the sealing of the connection between the cover body 1 and the connector, and the second anti-slip portion 203 defines a wire passing hole. The second anti-slip portion 203 can enhance the sealing between the waterproof rubber ring 2 and the cable. The diameter of the cable is larger than the diameter of the wire passing hole, so that the second anti-slip portion 203 needs to be compressed when the cable passes through, thereby improving the tightness of the connection between the waterproof rubber ring 2 and the cable.

[0048] It can be understood that the support portion 10 is embedded in the rubber ring body 201 in the radial direction of the rubber ring body 201 .

[0049] like Figure 2 As shown, in some embodiments, the first anti-slip portion 202 and the second anti-slip portion 203 both include a multi-circle portion 204 , the sub-portion 204 extends along the circumference of the rubber ring body 201 , and the multi-circle portions 204 are spaced apart along the axial direction of the rubber ring body 201 .

[0050] In detail, the first anti-slip portion 202 and the second anti-slip portion 203 both include a multi-circle portion 204, and the sub-portion 204 extends along the circumference of the rubber ring body 201, which can maintain uniform sealing in the circumferential direction, and the multi-circle portion 204 is spaced apart along the axial direction of the rubber ring body 201, thereby uniformly increasing the fit between the waterproof rubber ring 2 and the cable in the axial direction and improving the sealing.

[0051] In a specific embodiment, the cross-sectional shape of the sub-portion 204 is V-shaped, which can maximize the fit between the cable and the waterproof rubber ring 2 and between the waterproof rubber ring 2 and the connector, thereby improving the sealing performance.

[0052] like Figure 3 As shown, in some embodiments, the first anti-slip portion 202 avoids the stopper 20 .

[0053] In detail, the first anti-slip portion 202 avoids the stopper portion 20 , so that the difficulty of molding the waterproof rubber ring 2 can be reduced, and it is convenient to use the cover body 1 to cast the waterproof rubber ring 2 in liquid silicone on the basis of the cover body 1.

[0054] like Figure 1 As shown, according to the sealing structure of the embodiment of the present application, the cover body 1 further includes a clamping portion 40, and the clamping portion 40 is located on the outside of the waterproof rubber ring 2, and the cover body 1 and the waterproof rubber ring 2 are integrally formed.

[0055] Specifically, the clamping portion 40 is used to clamp with the connector. The integral molding of the cover body 1 and the waterproof rubber ring 2 can enhance the structural strength of the cover body 1, and can make the cover body 1 and the waterproof rubber ring 2 tightly combined and not easy to separate, thereby reducing the gap between the two. When the cable is bent or tilted, the support portion 10 will drive the waterproof rubber ring 2 to adaptively shift synchronously with the cable, thereby alleviating the relative shift between the cable and the waterproof rubber ring 2, and avoiding or alleviating the irregular shift or compression of the waterproof rubber ring 2 by the cable as much as possible, thereby improving the reliability of the sealing of the waterproof rubber ring 2, and then ensuring the support for the waterproof rubber ring 2, thereby improving the reliability of the sealing structure.
