Abstract: A safety socket has an insertion block, a base and a conducting unit. The insertion block has an inner housing and two support frames mounted in the inner housing. The base has an outer housing covered on the inner housing and two guide arms mounted in the outer housing. The conducting unit is mounted between the support arms and between the guide arms. When two blades of a plug are plugged in the insertion block and pushed inwardly, the conducting unit is rotated to electrically connect with the two blades. Each one of the guide arms and the two blades is held between the conducting unit and the corresponding support arm to keep the plug from being unplugged arbitrarily. When the insertion block is pushed again, the conducting unit is rotated and the plug can be easily unplugged.

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.

Abstract: A modified male connector on an internal power supply cord of a personal computer is provided. The modified connector enables easy unplugging of the connector of the power supply cord from the female connector of an electronic device. The invention is characterized in that two compressible tabs are created on two opposing sides of the male connector. One end of the compressible tabs will be lined up touching against the outer rim of the female connector when the male connector is mated with the female connector. When unplugging the male connector, users have only to slightly depress the compressible tab, and male connector will be loosened and pushed out from the female connector.
