This includes a socket 1 including a matching seal frame structure 11 and a male terminal rubber core component structure 12, and a plug 2 including a wire seal structure 21 and a female terminal rubber core component contact structure 22.

Since the lead-out of the terminal is changed from 180° to 90°, the lead-out space becomes wider, the terminal is less likely to shift, and the position is improved. A cantilever hook 1221 is fixedly provided on the metal buckle 122, and the matching seal frame structure 11 is connected to the male terminal rubber core component structure 12 via the cantilever hook 1221.

The present invention solves the problem of poor contact by arranging a grounding terminal with an innovative structure so that the contact between the grounding terminal and the metal shell is more stable. 5. By providing a metal shield shell, the present invention has a better shielding effect and more convenient wiring, and can improve the wiring efficiency. 6. By making the plug rubber core an integral structure, the present invention solves the problems of the split plug rubber core such as complex structure, poor wiring efficiency, easy detachment, and distortion after assembly, simplifies the structure and makes it more stable, increases the lead-out space, makes the terminals less likely to shift, and has a good position. 7. By arranging the punching locking rod and adding the side backstop structure, the present invention solves the problems of low dimensional accuracy and insufficient stability of the die-cast parts, and the insufficient backstop holding force after the engagement of the locking rod. Since the die-cast parts are changed to punched parts, the cost is reduced, the dimensional accuracy and stability are improved, and the holding force after the matching of the drive lever is improved.
