[0021] In this embodiment, the utility model provides a self-locking connector, which can better achieve self-locking.

[0022] like Figure 1 and Figure 2 As shown, in one embodiment of the utility model, the self-locking connector of the utility model includes a connector female seat structure and a connector male seat structure. The connector male seat structure is detachably connected to the connector female seat structure. When in use, the connector male seat structure is inserted into the connector female seat structure to achieve self-locking.

[0023] Specific reference Figure 1 and Figure 2The connector male seat structure includes a middle sleeve 1, a clamping coil 2, a nut 3, a first waterproof ring 4, a plurality of pins 5, a male rubber core 6, a self-locking lock ring 7 and a spring 8. The clamping coil 2 is arranged on the right side of the middle sleeve 1, the nut 3 is threadedly connected to the right end of the middle sleeve 1, a plurality of pins 5 are inserted on the male rubber core 6 and the right end of the male rubber core 6 is threadedly connected to the left end of the middle sleeve 1, and the self-locking lock ring 7 is rotatably installed on the left end of the male rubber core 6 through the spring 8. The spring 8 of the utility model is mainly used to help the self-locking lock ring 7 to reset after the self-locking lock ring 7 is rotated, so as to better realize self-locking. When used specifically, in order to quickly realize self-locking, the self-locking lock ring 7 rotated at a certain angle can be more convenient The self-locking locking ring 7 is convenient for realizing the connection with the connector female seat structure. At this time, the self-locking locking ring 7 is rotated, and the spring 8 is squeezed (specifically, it can be squeezed on the male rubber core 6). After the rotation angle, the connector female seat and the self-locking locking ring 7 can be better connected. After the connection, the self-locking locking ring 7 is released, and the spring 8 can be reset to help the self-locking locking ring 7 to reset and rotate, thereby better realizing the self-locking connection and the connection effect. To a certain extent, it also prevents skewness during the insertion process. The first waterproof ring 4 is sleeved on the right end of the male rubber core 6 and is located in the middle sleeve 1. A plurality of locking blocks are provided on the inner wall of the self-locking locking ring 7. The self-locking locking ring 7 is self-locked with the connector female seat structure through a plurality of locking blocks.

[0024] The connector female seat structure of the present invention includes a seat 9, a gasket 10, a hexagonal nut 11, a second waterproof ring 12 and a plurality of socket parts 13. The number of the plurality of socket parts 13 is equal to the number of the plurality of pins 5 and is arranged one-to-one. The plurality of socket parts 13 are arranged in the seat 9. The outer wall of the seat 9 is provided with a plurality of locking blocks. The number of the plurality of locking hooks is equal to the number of the plurality of locking blocks and is arranged one-to-one. The self-locking lock ring 7 is self-locked by the plurality of locking blocks and the plurality of locking hooks of the connector female seat structure. The gasket 10 is sleeved on the seat 9. The hexagonal nut 11 is threadedly connected to the seat 9. The right end portion of the seat 9 is inserted to the right into the self-locking lock ring 7 and sleeved on the left end portion of the male rubber core 6.

[0025] The specific use process of the utility model is that the pin 5 can be electrically connected to the connecting wire and thus led out from the clamp coil 2 and the nut 3, the connector female seat structure can also be connected to other connecting wires and finally realize self-locking with the connector male seat structure. During the specific self-locking connection, the self-locking lock ring 7 is rotated so that the locking hook is smoothly inserted between the locking blocks in the self-locking lock ring 7, and then the self-locking lock ring 7 is released. The self-locking lock ring 7 can be reset under the action of the spring 8, and the pin 5 is specifically inserted into the socket part 13. The utility model rotates the self-locking lock ring 7 to help the insertion end of the locking hook to be just aligned between the two adjacent locking blocks, so that it can be smoothly inserted to prevent skewing. The spring 8 can also help the self-locking lock ring 7 to reset, thereby making the self-locking connection effect better.

[0026] This embodiment does not impose any formal restrictions on the shape, material, structure, etc. of the utility model.
