Abstract
The present disclosure discloses a safety plug comprising two pins, an insulating housing, a limiting member, and an operating member. The operating member is configured to drive the limiting member to be changed between a position-limited position and an unlocked position. First ends of the two pins extend into the insulating housing, a short-circuit protection circuit is disposed in the insulating housing, and the short-circuit protection circuit is disposed in a path in which the two pins move away from the insulating housing. When the limiting member is in the position-limited position, a limiting fit is defined, and the first ends of the two pins are spaced apart from the short-circuit protection circuit. When the limiting member is in the unlocked position, the limiting fit is released, and the insulating housing is pulled to enable the short-circuit protection circuit to short circuit the two pins.
