[0025] Example: This example provides an insulated and waterproof wire harness connector, see [link / reference]. Figure 1-6Specifically, it includes a male plug 1 and a female plug 12, with their ends tightly touching. A first sleeve 11 is fixedly mounted on the male plug 1, and a retaining ring 13 is fixedly mounted on the female plug 12. A second sleeve 14 is rotatably mounted on one side of the retaining ring 13, and a thread is formed on one side of the second sleeve 14. A threaded groove 15 is formed inside the first sleeve 11, and the second sleeve 14 is threadedly connected to the threaded groove 15. A sealing assembly is provided on the first sleeve 11 and the retaining ring 13. The sealing assembly includes a first rubber gasket 2, a second rubber gasket 21, and a rubber sleeve 3. The middle part of 14 is hexagonal. The first rubber pad 2 is fixedly installed in the threaded groove 15. The second rubber pad 21 is fixedly installed at the end of the first sleeve 11. The rubber sleeve 3 is fitted on the fixing ring 13 and the second sleeve 14. The rubber sleeve 3 is fixedly connected to the second sleeve 14. The rubber sleeve 3 has a crease 31 located at the connection between the fixing ring 13 and the second sleeve 14. The male plug end 1 is fixedly provided with multiple plug terminals 4. The female plug end 12 has multiple plug holes 41. The multiple plug terminals 4 are plugged into the multiple plug holes 41.

[0026] Insert the second sleeve 14 into the threaded groove 15 and rotate it. The second sleeve 14 continues to advance into the threaded groove 15, while the connector 4 is slowly inserted into the connector hole 41 until it is fully inserted. The second sleeve 14 compresses the second rubber pad 21, causing it to deform and completely fill the connection between the first sleeve 11 and the second sleeve 14, achieving the first level of waterproofing. The second sleeve 14 then compresses the first rubber pad 2, causing it to deform and completely fill the connection between the second sleeve 14 and the bottom of the threaded groove 15, achieving the second level of waterproofing. For first-level waterproofing, before installation, the rubber sleeve 3 is folded along the crease 31 onto the part of the second sleeve 14 and onto the retaining ring 13. After the first sleeve 11 and the second sleeve 14 are connected, the rubber sleeve 3 is then lowered along the crease 31. The rubber sleeve 3 seals the connection between the retaining ring 13 and the second sleeve 14, achieving third-level waterproofing. Multiple sealing gaskets provide waterproofing, resulting in a rich waterproofing structure and good waterproofing effect. It is not easy for water to enter or leak, greatly reducing safety hazards. The hexagonal shape of the middle part of the second sleeve 14 is for easy rotation of the wrench.

[0027] Multiple first copper wires 5 are fixed inside the first rubber pad 2, and multiple second copper wires 51 are fixed inside the second rubber pad 21. The multiple first copper wires 5 and multiple second copper wires 51 are evenly distributed inside the first rubber pad 2 and the second rubber pad 21, respectively.

[0028] The first copper wire 5 and the second copper wire 51 can greatly improve the practical strength of the first rubber pad 2 and the second rubber pad 21, avoid the rubber pads from becoming loose due to long-term or repeated disassembly, greatly extend the service life of the rubber pads, and have strong practicality.

[0029] Specifically, the working principle and operation method of this utility model are as follows:

[0030] Insert the second sleeve 14 into the threaded groove 15 and rotate the second sleeve 14. The second sleeve 14 will continue to enter the threaded groove 15. During this process, the plug terminal 4 will be slowly inserted into the plug terminal hole 41 until it is fully inserted. The second sleeve 14 will squeeze the second rubber pad 21. The second rubber pad 21 will be deformed by the compression and completely fill the connection between the first sleeve 11 and the second sleeve 14 to achieve the first level of waterproofing.

[0031] The second sleeve 14 squeezes the first rubber pad 2, causing the first rubber pad 2 to deform under the pressure, completely filling the connection between the second sleeve 14 and the bottom of the threaded groove 15, thus achieving the second level of waterproofing.

[0032] Before installation, the rubber sleeve 3 is folded along the crease 31 onto the part of the second sleeve 14 and onto the fixing ring 13. After the first sleeve 11 and the second sleeve 14 are connected, the rubber sleeve 3 is put down along the crease 31. The rubber sleeve 3 seals the connection between the fixing ring 13 and the second sleeve 14, providing third-level waterproofing. Multiple sealing gaskets provide waterproofing, resulting in a rich waterproofing structure and good waterproofing effect. It is not easy for water to enter or leak, greatly reducing safety hazards.

[0033] The first copper wire 5 and the second copper wire 51 can greatly improve the practical strength of the first rubber pad 2 and the second rubber pad 21, avoid the rubber pads from becoming loose due to long-term or repeated disassembly, greatly extend the service life of the rubber pads, and have strong practicality.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
