Description

Technical Field

[0001] The utility model relates to the technical field of sealing rings, in particular to a waterproof sealing gasket for vehicle-mounted connectors. Background Technique

[0002] In the assembly of new energy vehicle parts, vehicle-mounted connectors for power sources need to achieve strict sealing effects to prevent internal circuits from getting water, which may cause short circuits and affect vehicle safety.

[0003] There is a type of existing vehicle-mounted connector whose assembly surface has multiple mounting threaded holes. Traditional sealing rings only seal the gaps on the assembly surface and cannot eliminate the mounting gaps at the edges of the threaded holes, resulting in poor sealing effects. Content of the Utility Model

[0004] The purpose of the utility model is to provide a waterproof sealing gasket for vehicle-mounted connectors to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A waterproof sealing gasket for vehicle-mounted connectors provided by the utility model includes a connector and a sealing ring body. The sealing ring body is embedded in the connector. The sealing ring body includes a rectangular sealing part. An orifice sealing part is arranged inside the rectangular sealing part. Both upper and lower ends of the rectangular sealing part are provided with a gap one and a gap two. The orifice sealing part includes two left positioning holes, a middle positioning hole, and a right positioning hole.

[0007] Further, the orifice sealing part and the rectangular sealing part are of an integrally formed structure, and the heights of the upper and lower end faces of the orifice sealing part are both smaller than the height of the rectangular sealing part.

[0008] Further, the two left positioning holes and the right positioning hole are both arranged at the diagonal positions of the rectangular sealing part.

[0009] Further, the two middle positioning holes are centered in the length direction of the rectangular sealing part.

[0010] Further, both the gap one and the gap two have arc chamfers, and the bottom surface heights of the gap one and the gap two are flush with the upper and lower end faces of the orifice sealing part.

[0011] Further, the two gap ones and the gap two are arranged corresponding to each other up and down.

[0012] Further, both the inner and outer sides of the rectangular sealing part are provided with arc chamfers.

[0013] Beneficial effects: A waterproof sealing gasket for vehicle-mounted connectors realizes the all-round sealing of vehicle-mounted connectors through the integrated combined structure of a rectangular sealing part and a hole-position sealing part, has a good sealing effect, and can be installed on both the front and back sides, saving assembly time.

[0019] The following are specific embodiments of the present invention in combination with the drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0020] Embodiment

[0021] As Figures 1-3 shown, a waterproof sealing gasket for vehicle-mounted connectors includes a connector 1 and a sealing ring body 2. The sealing ring body 2 is embedded on the connector 1. The sealing ring body 2 includes a rectangular sealing part 21, and a hole-position sealing part 22 is arranged inside the rectangular sealing part 21. Gap 1 211 and gap 2 212 are arranged at both the upper and lower ends of the rectangular sealing part 21. The hole-position sealing part 22 includes two left positioning holes 221, a middle positioning hole 222, and a right positioning hole 223.

[0022] In Embodiment 1, the hole-position sealing part 22 and the rectangular sealing part 21 are of an integrally formed structure, and the heights of the upper and lower end faces of the hole-position sealing part 22 are both smaller than the height of the rectangular sealing part 21, ensuring that after the rectangular sealing part 21 is embedded in the connector 1 for assembly, the hole-position sealing part 22 is in close fit with the lower end of the positioning hole for seamless assembly. Both of the two left positioning holes 221 and the right positioning hole 223 are arranged at the diagonal positions of the rectangular sealing part 21, and the two middle positioning holes 222 are arranged in the middle of the length direction of the rectangular sealing part 21. The left positioning hole 221, the middle positioning hole 222, and the right positioning hole 223 all correspond to the positions of the threaded holes on the surface of the connector 1.

[0023] Embodiment 2: Both the first gap 211 and the second gap 212 have arc-shaped chamfers. The bottom surface heights of the first gap 211 and the second gap 212 are flush with the upper and lower end faces of the hole position sealing part 22. The two first gaps 211 and the second gaps 212 are arranged corresponding to each other up and down. The first gaps 211 and the second gaps 212 enable the sealing ring body 2 to have uniform compressive stress, avoiding deformation or cracking after being locally extruded. The design of the arc-shaped edge makes the overall structure of the sealing ring body 2 fit closely with the connector 1.

[0024] After the sealing ring body 2 and the connector 1 are assembled with each other, the upper end face of the sealing ring body 2 protrudes from the assembly surface height of the connector 1, eliminating the fitting gap between the connector 1 and the installation device, achieving a sealing effect. The hole position sealing part 22 is adaptively installed with a plurality of threaded holes on the connector 1, eliminating the gap at the edge of the installation hole and further strengthening the sealing effect. The sealing ring body 1 can be installed in the forward or reverse direction, saving the assembly time.

[0025] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
