Details are not described herein.

[0038] In further embodiments, considering that the plugging force of the connector is large, a structure facilitating disassembly and assembly is arranged on the first connecting part 1 and the second connecting part 2 during design. Specifically, in the embodiment, a mounting hole is arranged on the first fixing frame 13. An auxiliary part 3 is movably arranged in the mounting hole. In general, the auxiliary part 3 uses a bolt, and the mounting hole is a threaded hole. When the first connecting part 1 and the second connecting part 2 need to be separated, the auxiliary part 3 is rotated to move and press the second fixing frame 23, so that the first connecting part 1 and the second connecting part 2 are separated. The mounting hole is arranged in the middle of the first fixing frame 13.

Considering that the second connecting part 2 (the socket) is basically fixed on the equipment for use, the mounting part 21 is also fixed on the second fixing frame 23, so as to facilitate the connection between the second connecting part 2 and the equipment.

[0040] The first fixing frame 13 is rotatably provided with a locking part 17. The locking part 17 is a top ejection bolt, which is axially movably installed in the through hole of the first fixing frame 13. A threaded hole is arranged at the corresponding position of the second fixing frame 23. The locking part 17 is threadedly connected with the second fixing frame 23. The rotation of the locking part 17 locks the first insulator 12 and the second insulator 22.

[0041] It is worth noting that in the present embodiment, two locking parts 17 and two mounting parts 21 are arranged. The two locking parts 17 and the two mounting parts 21 are arranged at the diagonal positions of the two first fixing frames 13. When the locking part 17 is used, the stability of the movement of the first insulator 12 and the second insulator 22 is improved, and the deviation of the second connecting part 2 is prevented.

[0042] In a further embodiment, considering the guiding property of the connector, a first guiding part 16 is fixed on the first fixing frame 13, and a second guiding part 26 is arranged on the second fixing frame 23. The first guiding part 16 is inserted into the cavity of the second guiding part 26 when the connector is inserted. The same direction design operation is also possible. Finally, the first connecting part 1 and the second connecting part 2 are directionally connected and inserted, so as to reduce the generation of deviation stress. When the guiding part is fixed, it can also serve as a connecting part for fixing the corresponding fixing frame and the spring sheet.

[0043] In the use of the connector:

[0044] The second connecting part 2 is fixed on the equipment, which can be fixed on the vehicle body. The operator moves the first connecting part 1 towards the second connecting part 2, so that the male and female terminals are combined. When the locking part 17 is used to the extent, the locking part 17 is rotated to combine the first connecting part 1 and the second connecting part 2. During the process, the first guiding part 16 and the second guiding part 26 are cooperatively guided to ensure the accuracy of the direction of the insertion. During the process, the tension on the upper edge of the two insulators is transmitted to the entire first insulator 12 and the second insulator 22 through the corresponding gasket 15, the spring sheet and the fixing frame, so as to reduce the unilateral stress and avoid the risk of thread slipping of the knurled screw (fastener 11), thereby improving the plug-in life of the connector.

[0045] When the connector needs to be separated, the locking member 17 is loosened, and the auxiliary member 3 is rotated, so that the relative force between the first connecting part 1 and the second connecting part 2 is generated, and the separation of the connector is completed.
