The ground wire has the function of grounding the shell of the electric appliance, so as to prevent electric shock accidents when a user contacts the shell of the electric appliance. Under the condition that a leakage protection switch is connected into a line, if a current exists in a ground wire, the leakage protection switch is triggered to act, and a power supply circuit is cut off.

The ground and fire wire bays 200, 300 formed in the housing 100 are isolated from each other such that when water or conductive liquid enters the ground or fire wire bay 200, 300, the ground and fire wires do not communicate. In addition, the ground wire receptacle 200 refers to a space in which the ground wire connector is accommodated. A cofferdam 400 is formed around the upper part of the opening of the ground wire inserting cabin 200, a ground wire separating cavity 130 is formed inside the cofferdam 400, and a ground wire jack 210 is formed inside the ground wire separating cavity 130 by the surface shell, so that when water or conductive liquid enters, due to the separation effect of the cofferdam 400, the water or conductive liquid can only enter the ground wire inserting cabin 200 or the live wire inserting cabin 300 independently, and the ground wire in the ground wire inserting cabin 200 and the live wire in the live wire inserting cabin 300 are not communicated through the water or the conductive liquid. Therefore, the problem that the leakage protection switch detects leakage current due to accidental water inflow of any socket with a ground wire in the existing power supply circuit, and then the whole power supply circuit is cut off under the unnecessary condition is solved.
Currently, for electrical safety, the socket needs to be provided with a protective door to prevent the charged portion from being exposed from the jack, the protective door structure is generally provided at the face-piece unit 120, and water or conductive liquid generally enters from the face-piece unit 120, so that the separation of the cofferdam 400 is required to act on the water or conductive liquid entering from the face-piece unit 120.

The cofferdam 400 is located between the first housing 121 and the second housing 122 so that water or conductive liquid entering from the face housing unit 120 can be separated by the cofferdam 400, so that the ground in the ground jack 200 and the live in the live jack 300 cannot communicate through the water or conductive liquid.
It should be noted that the present embodiment may be suitable for wall insertion, the bottom case unit 110 may be embedded in a wall, and the face case unit 120 faces out of the wall.
Optionally, the trim panel 800 is secured over the face unit 120.
It should be noted that, the separation of the cofferdam 400 is required to enable water or conductive liquid to only enter the ground wire bay 200 or the live wire bay 300, so as to achieve the effect that the ground wire in the ground wire bay 200 and the live wire in the live wire bay 300 are not communicated through the water or conductive liquid.
