Abstract: A power plug, including: a shell, the shell having two sides, a reset button and a test button protruding from the first side, and a live wire pin and a neutral wire pin protruding from the second side; a circuit board; a stationary contact; a movable contact; a tripping device; a cross arm; and a push block. The stationary contact is connected with the live wire pin and the neutral wire pin; the movable contact can be connected to or disconnected from the stationary contact. The tripping device includes a sliding pedestal and a sliding part and controls the connection between the movable contact and the stationary contact. An elastic member is disposed on the push block. An ejector spring is disposed on one end of the movable armature. A reset spring is disposed between the sliding part and the sliding pedestal.

Abstract: A plug including a shell and a mounting body disposed inside the shell. The mounting body is provided with a first movable contact spring and a second movable contact spring, a phase contact and a zero contact, and a button assembly. A transverse block disposed above the first movable contact spring and the second movable contact spring includes a phase terminal and a zero terminal. The button assembly includes an electric magnet disposed on the mounting body and a sliding part having a cavity. The cavity of the sliding part is provided with a reset spring. A hook is disposed in a lower part of the cavity. The transverse block is connected with a pull block. An upper part of the pull block is connected with the electric magnet. The center of the pull block includes a limiting hole for accommodating the hook.
