[0026] Further, sub-connector 1 lower end is fixedly connected with plug-in part 101, female connector 4 upper end is provided with plug-in groove 401, and sub-connector 1 and female connector 4 are limitedly connected by inserting plug-in part 101 into plug-in groove 401 inside, so that sub-connector 1 and female connector 4 are preliminarily connected.

[0027] Further, the middle part of one side end face inside two rectangular limiting sliding grooves 202 of rectangular self-locking part 2 is fixedly connected with guide rod 203, the middle part inside rectangular sliding block 3 is fixedly connected with circular groove 301, one end of guide rod 203 is inserted into the inside of circular groove 301, and spring 302 is arranged in the inside of circular groove 301.

[0028] Further, the two locking plates 501 on the female connector 4 are respectively inserted into the locking grooves 201 of the two rectangular self-locking portions 2 on the male connector 1, and the two second triangular locking tongues 502 on the two sides of the locking plates 501 are moved to the upper ends of the two first triangular locking tongues 303. When the insertion portion 101 is gradually inserted into the insertion groove 401, the locking plate 501 gradually extends into the locking groove 201. After the upper ends of the two second triangular locking tongues 502 contact the lower ends of the two first triangular locking tongues 303, the first triangular locking tongue 303 is moved to one side under the extrusion of the second triangular locking tongue 502 and is withdrawn into the rectangular limiting sliding groove 202, so that the locking plate 501 is completely inserted into the locking groove 201. After the second triangular locking tongue 502 moves to the upper end of the first triangular locking tongue 303, the first triangular locking tongue 303 is withdrawn from the rectangular limiting sliding groove 202, which pushes the rectangular sliding block 3 to move, so that the guide rod 203 extends into the circular groove 301 and compresses the spring 302.
