[0044] The male seat module 1 includes a male seat body 11 and a male connector 12 formed on the male seat body 11, the male connector 12 is movably embedded with a locking ring 13, and the inner wall of the locking ring 13 is formed with an internal thread structure 14; the female seat module 2 includes a female mounting seat 21 and a female connecting sleeve 22 connected to the female mounting seat 21, the female connecting sleeve 22 is formed with a female connecting groove 23 for the male connector 12 to be inserted, and the outer wall of the female connecting groove 23 is formed with an external thread structure 24 threadably matched with the internal thread structure 14;

[0045] When the male module 1 and the female module 2 are connected, the male connector 12 of the male body 11 is inserted into the female connecting groove 23 of the female connecting sleeve 22, and then the locking ring 13 is moved close to the female connecting sleeve 22. The locking ring 13 is threadedly engaged with the external thread structure 24 of the outer wall of the female connecting groove 23 through the internal thread structure 14 to lock the male module 1 and the female module 2.

[0046] Specifically, the outer end surface of the male connector 12 is formed with a plurality of concave metal conductive grooves 15, and the inner end surface of the female connecting groove 23 is convexly formed with a plurality of conductive contacts 25 arranged axially along the female connecting sleeve 22, and the conductive contacts 25 are coaxially aligned with the metal conductive grooves 15; when the male socket module 1 and the female socket module 2 are connected, the metal conductive grooves 15 on the outer end surface of the male connector 12 are close to the conductive contacts 25 of the female connecting sleeve 22, and after locking is completed, the metal conductive grooves 15 and the conductive contacts 25 are coaxially contacted to achieve stable conduction and maintain the stability of signal transmission.

[0047] A guide structure for guiding the male connector 12 to be inserted into the female connector groove 23 is provided between the male connector module 1 and the female connector module 2. The guide structure includes a guide bar 16 arranged axially along the outer wall of the male connector 12, and a guide groove 26 for sliding fit of the guide bar 16 is formed axially on the inner ring wall of the female connector groove 23. When the male connector module 1 and the female connector module 2 are connected, when the male connector 12 is inserted into the female connector groove 23, the guide bar 16 will slide with the guide groove 26. At this time, the male connector 12 and the female connector sleeve 22 will not rotate, and the axial splicing is maintained, so that the metal conductive groove 15 and the conductive contact 25 can be in coaxial contact, thereby improving the stability of signal transmission.

[0048] Preferably, the number of guide bars 16 and guide grooves 26 is the same, both are more than four, and the distance between two adjacent guide bars 16 is the same, and the distance between two adjacent guide grooves 26 is the same.

[0049] A waterproof structure 3 is provided between the male module 1 and the female module 2. The waterproof structure 3 can be used to waterproof the interior between the male module 1 and the female module 2, thereby reducing the occurrence of short circuits.

[0050] Specifically, the waterproof structure 3 includes an inner waterproof gasket 31 installed at the inner end of the female connection groove 23, the outer end surface of the inner waterproof gasket 31 is formed with an annular waterproof groove 34, the outer end wall of the male connector 12 is installed with an outer waterproof gasket 32, the outer end surface of the outer waterproof gasket 32 ​​is formed with an annular waterproof block 33, and the waterproof block 33 is in elastic sealing contact with the waterproof groove 34; after the male seat module 1 and the female seat module 2 are locked and connected, the outer waterproof gasket 32 ​​of the outer end wall of the male connector 12 will contact the inner waterproof gasket 31 at the inner end of the female connection groove 23, and at the same time, the waterproof block 33 on the outer end surface of the outer waterproof gasket 32 ​​will be embedded in the waterproof groove 34 on the outer end surface of the inner waterproof gasket 31. At this time, the inner waterproof gasket 31 and the outer waterproof gasket 32 ​​are sealed and connected, the metal conductive groove 15 and the conductive contact 25 are not easy to wade in water, and the waterproof effect is better.

[0051] Furthermore, the outer ring wall of the inner waterproof gasket 31 is formed with an engaging block 35 embedded in the guide groove 26. The engaging block 35 can prevent the inner waterproof gasket 31 from rotating in the female connection groove 23, thereby ensuring the sealing of the male seat module 1 and the female seat module 2 after the locking connection.

The left connecting ring 52 is formed with a threaded hole 57 which is threadedly matched with the threaded rod 55, and the transverse ring 54 and the right connecting ring 53 are respectively coaxially formed with movable holes 56 for the threaded rod 55 to pass through; the threaded rod 55 can be rotatable so that the threaded rod 55 is threadedly matched with the threaded hole 57 of the left connecting ring 52, and the left connecting ring 52 and the right connecting ring 53 can approach each other, and the soft connecting sleeve 51 is compressed by the left connecting ring 52 and the right connecting ring 53, so that the wiring harness can be compressed, thereby preventing the wiring harness from moving along the length direction of the soft connecting sleeve 51, thereby improving its connection stability.

[0057] Furthermore, the connecting structure is respectively arranged at the top and bottom of the left connecting ring 52 and the right connecting ring 53. The inner walls of the left connecting ring 52 and the right connecting ring 53 are respectively formed with annular grooves 58 that contact the soft connecting sleeve 51.
