DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor fall within the scope of protection of the present utility model.

[0026] Please refer to Figure 1 Figure 5 The utility model provides technical scheme: a waterproof wiring harness connector, including connector main part 1, connector main part 1 includes first terminal 101 and second terminal 102, and the side that first terminal 101 and second terminal 102 are away from each other all are installed with wiring harness, and the other side of second terminal 102 is fixedly installed with plugboard 104, and the other side of first terminal 101 is fixedly connected with plug 103;

[0027] The outside of first terminal 101 is provided with docking assembly 2, and docking assembly 2 includes the wrapping cover 201 fixed to the outside of first terminal 101, the fixed ring 202 is fixedly connected to the outside of wrapping cover 201, the extension cover 203 is fixedly connected to the other outside of wrapping cover 201, the sliding ring 204 is slidably connected to the outside of extension cover 203, the end face edge of wrapping cover 201 is provided with ring groove 205, the waterproof sleeve 206 is fixedly connected in the inside of ring groove 205, and the waterproof ring 214 is fixedly connected to the inner side of extension cover 203;The waterproof sleeve 206 is provided with a cover shape, is fixedly installed in the inner wall of ring groove 205, and the docking ring 212 is inserted into ring groove 205 and is attached to waterproof sleeve 206, to form a bending structure and carry out secondary waterproofing.

[0028] Wherein, one side of sliding ring 204 is fixedly connected with rectangular spring 215, the other side of sliding ring 204 is fixedly connected with extrusion ring 207, a plurality of through grooves 208 are formed in the inside of extension cover 203, and the bottom of through groove 208 is slidably connected with round head column 210;The number of through groove 208 is same as that of round head column 210.

[0029] Wherein, the outside of plugboard 104 is fixedly connected with docking ring 212, docking ring 212 is inserted into ring groove 205, a plurality of spherical grooves 211 are formed in the outside of docking ring 212, spherical groove 211 is embedded with round head column 210;A plurality of are distributed on the outside of docking ring 212 and are not less than four.

[0030] The waterproof sleeve 206 is attached to the docking ring 212, and the waterproof ring 214 is attached to the outside of the docking ring 212;The waterproof ring 214 can carry out primary waterproofing.

[0031] ​A clearance hole is provided in the middle of the waterproof ring 214, which is connected to the through groove 208. The round-headed post 210 passes through the clearance hole and engages with the spherical groove 211. The engagement of the round-headed post 210 and the spherical groove 211 can prevent the coupling ring 212 of the cover 201 from separating, increasing the stability after the first terminal 101 and the second terminal 102 are connected. This avoids the need for bolts and facilitates the separation and disassembly of the two wire harnesses. The self-locking structure prevents the first terminal 101 and the second terminal 102 from separating due to the pulling of the wire harness, increasing its stability during use.

[0032] The compression ring 207 fits against the outer side of the extension cover 203 and is fitted against the top of the round-headed pillar 210; the compression ring 207 can...

[0033] The through groove 208 is symmetrically provided with limiting grooves 209 on both sides. The limiting groove 209 is slidably connected to the limiting block 213. The limiting block 213 is fixedly connected to the outside of the round head post 210. The limiting groove 209 is opened inside the extension cover 203. The limiting groove 209 and the limiting block 213 can prevent the round head post 210 from falling out of the through groove 208 and limit the movement range of the round head post 210.

[0034] The end of the rectangular spring 215 away from the sliding ring 204 is fixedly connected to the fixing ring 202. The rectangular spring 215 is sleeved on the outside of the cover 201. The rectangular spring 215 can push the sliding ring 204 so that the compression ring 207 covers the outside of the through groove 208.

[0035] Working principle: Before using this type of waterproof wire harness connector, it is necessary to check the overall condition of the device to ensure it can function normally. Figure 1 - Figure 5 As shown, firstly, by moving the sliding ring 204, the rectangular spring 215 contracts, while the compression ring 207 moves horizontally and moves away from the outside of the through groove 208. At this time, the plug 103 and the socket 104 are aligned. During this process, the mating ring 212 is inserted into the annular groove 205, allowing the waterproof sleeve 206 to wrap around the annular groove 205, and the waterproof ring 214 to fit against the outside of the mating ring 212. Then, the sliding ring 204 is released, causing the compression ring 207 to move against the outside of the extension cover 203. By contacting the outer arc surface of the round head post 210, the round head post 210 is squeezed into the through groove 208, thereby allowing the round head post 210 to pass through the clearance groove and fit into the spherical groove 211. At the same time, the compression ring 207 fits against the outside of the round head post 210. The waterproof ring 214 can provide initial waterproofing, and the waterproof sleeve 206 can provide secondary waterproofing. The bending structure formed by the waterproof sleeve 206 and the connecting ring 212 can better prevent water from seeping into the connection between the plug 103 and the socket 104.

[0036] The engagement of the round head post 210 and the spherical groove 211 can prevent the separation of the cover 201 and the connecting ring 212, increase the stability after the first terminal 101 and the second terminal 102 are connected, thereby avoiding the need for bolts and facilitating the separation and disassembly of the two wire harnesses. The structure with a built-in locking buckle prevents the first terminal 101 and the second terminal 102 from separating due to the pulling of the wire harness, increasing its stability during use.

[0037] Although the present invention 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 the present invention should be included within the protection scope of the present invention.
