The sealing part includes a plug body, and a first sealing lip, a second sealing lip and a third sealing lip are provided on the outside of the plug body. Multiple support parts are provided between the first sealing lip, the second sealing lip and the third sealing lip.

[0007] Furthermore, the diameter of the first wire portion is larger than that of the second wire portion, and the first wire portion, the second wire portion, and the sealing portion are integrally formed.

[0008] Furthermore, the through groove is a waist-shaped groove, and a limiting tooth is provided inside the through groove.

[0009] Furthermore, the first sealing lip and the third sealing lip have the same structure, and one end of the first sealing lip is provided with a dustproof protrusion, which is rounded to the end face of the first sealing lip.

[0010] Furthermore, the edge of the plug is provided with a plurality of extrusion grooves, which respectively penetrate the first sealing lip, the second sealing lip and the third sealing lip, and the extrusion grooves have open ends.

[0011] Furthermore, the plurality of support portions are located on one side of the extrusion groove, and an extrusion cavity is formed inside the support portion.

[0012] Beneficial effects: A columnar dustproof rubber sealing ring, with a design structure of support, extrusion groove and matching dustproof protrusion between multiple sealing lips, can reduce the amount of deformation caused by lateral and vertical pressure during the assembly of the sealing part, prevent dust from entering the sealing cavity through the deformed gap, and ensure the sealing effect.

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] Example

[0020] like Figure 1-3 As shown, a columnar dustproof rubber sealing ring includes a sealing part 1, with a first guide wire part 2 and a second guide wire part 3 respectively provided at both ends of the sealing part 1. A through groove 4 is provided in the sealing part 1, the first guide wire part 2 and the second guide wire part 3. The sealing part 1 includes a plug body 5, with a first sealing lip 6, a second sealing lip 7 and a third sealing lip 8 provided on the outside of the plug body 5. Multiple support parts 9 are provided between the first sealing lip 6, the second sealing lip 7 and the third sealing lip 8.

[0021] In Embodiment 1, the diameter of the first conductor section 2 is larger than that of the second conductor section 3. The first conductor section 2, the second conductor section 3, and the sealing section 1 are integrally formed. The through groove 4 is a waist-shaped groove, and the through groove 4 is provided with limiting teeth 10. The automotive connector wires pass through the first conductor section 2, the sealing section 1, and the second conductor section 3 in sequence from the through groove 4. The limiting teeth 10 inside the through groove 4 can allow multiple wire harnesses to be arranged side by side to prevent the wire harnesses from tangling.

[0022] In embodiment 2, the first sealing lip 6 and the third sealing lip 8 have the same structure. One end of the first sealing lip 6 is provided with a dustproof protrusion 11, which is rounded to the end face of the first sealing lip 6. After the plug body 5 is assembled, the dustproof protrusion 11 protrudes outside the connector sealing cavity to prevent dust and other objects from entering the sealing cavity. The plug body 5 also has multiple extrusion grooves 12 on its edge. After the plug body 5 is partially installed, the outer sealing lip is compressed by pressure. The multiple extrusion grooves 12 pass through the first sealing lip 6, the second sealing lip 7, and the third sealing lip 8 respectively, and the extrusion grooves 12 have open ends. Multiple support parts 9 are located on one side of the extrusion grooves 12. The support parts 9 have extrusion cavities 13 inside. The multiple support parts 9 can disperse the pressure through the extrusion cavities 13. The support parts can reduce the deformation caused by the vertical extrusion force of the first sealing lip 6, the second sealing lip 7, and the third sealing lip 8. The extrusion grooves 12 can reduce the deformation caused by the lateral extrusion force of the first sealing lip 6, the second sealing lip 7, and the third sealing lip 8.

[0023] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
