Abstract: The present invention relates to an improved structure of a socket which ensures a secured retention of a plug connected to the socket. The socket comprises a set of swinging rods being pivotally mounted at the central section of the bottom edge of the rod. A press-hold member enclosed a spring is disposed in between the space formed by the rods and is used to appropriately press and hold the pivotally connected bottoms edge of the rods such that the swinging rods can be opened (extended) or closed (retracted) about the pivoted point. When the prongs of a plug are inserted into the socket and pressed at the press and hold member, the bottom edge of the swinging rods which curved upward into a horizontal flat position are pressed. At this instance, the protrusion on the top end of the rods will be inserted into the hole provided at the end of the prongs as a result of forward movement of the swinging rods. Thus the prongs will not be dislocated when the plug is connected to the socket.

Abstract: The present invention relates to an improved structure of a socket comprising a socket body, a framework, a mounting seat, and a covering board. The framework is mounted at the center of the socket body and at the lateral edge of the framework, a plurality of channels are provided for the mounting of the mounting seat. A positioning member being urged by elastic elements is mounted to a horizontal slot which is formed at the central bottom region of the mounting seat. The front end of the positioning member is extended and spaced by a protruded end to form a protruded stopping disc having a slanting edge, which works together with a horizontal bar so as to cause the positioning member to slide laterally. The lower section of the mounting seat is provided with an engaging board, having a bottom face being urged by an elastic element. At normal condition, the upward movement of the engaging board positions the positioning member to the two lateral edges of the framework.

Abstract: A safety receptacle includes a base (10) formed with a circular depression (11) and two opposite cavities (18) one at a side of the depression, two conducting members (19) each fitted into a respective one of the cavities of the base, a rotary head (20) being a tubular member formed with a top having two parallel slots (20), a pair of opposite flanges (24) extending outwardly from two opposite sides of the tubular member, a block (28) depending downwardly from a central portion of a lower side of the top, and two vertical slots at two opposite sides of the tubular member, a positioning member (17) having an upper end fixedly fitted in the block of the rotary head and a lower end engaged with the recess, two terminals (22) each inserted into a respective one of the vertical slots along the two legs and provided with an inwardly extending tongue (221) , and a cover (30) fixedly mounted on the base and having a circular opening for receiving the top of the rotary head, whereby rotation of the plug (40) through 9
