The insulating case 11 defines an installation space 110, and the insulating cover 10 can be mounted with the device mounting space 110 to combine the insulating case 11 with the insulating cover 10. The inner wall of the insulating case 11 and the outer wall of the insulating cover 10 together form a mounting portion 112. And a waterproof ring 15 is disposed on the mounting portion 112, whereby the waterproof ring 15 can effectively isolate the external moisture or liquid inflow, thereby effectively achieving waterproofing and Anti-electric shock effect.

In addition, the insulating base 12 is mounted on the insulating upper cover 10.

During assembly, the live conductive terminal 120 and the neutral conductive terminal 122 are assembled. The grounding conductive terminals 124 are respectively disposed in the insertion tube body 104. Since the tube body 104 is in communication with the insertion hole 102, the conductive sheet (not shown) on the external plug can be directly electrically connected to the hot line after being inserted into the insertion hole 102. The terminal 120, the neutral conductive terminal 122 and the ground conductive terminal 124 are connected. In addition, the hot wire conductive terminal 120, the neutral wire conductive terminal 122, and the ground wire conductive terminal 124 are provided with a metal contact post 126 through which the insulating seat 12 is disposed and protruded from the other surface.
