ABSTRACT:
A power plug has a housing, two blades, a slider mounted through the housing, and a cylindrical resilient member mounted inside the housing. When the plug is unplugged, the ends of the blades inside the housing are not contacted with two spring leaves inside the housing. When the plug is plugged in a power socket, the slider abuts against the socket, moves into the housing and compresses the resilient member to become an oval shape. The distorted resilient member pushes the two blades inside the chamber to pivot to and contact with the respective spring leaves, and the ends of the two blades outside the chamber mutually close up to hold the power socket, preventing accidental release of the plug. When the power plug is unplugged, the elastic force released by the resilient member pushes the housing to move away from the power socket, making the plug easily unplugged.
