  • Patent number: 9425570
    Abstract: A power receptacle assembly includes a first housing, a second housing, one or more receptacle units, one or more functional receptacles, and a decorative bordered frame. Two or more through holes are disposed at lower portions of two opposing sides of the first housing to admit a hook portion formed by extending downward two outer sides of the second housing engaged with the one or more receptacle units and admit a hook portion formed by extending downward two outer sides of the one or more functional receptacle. Not only does the power receptacle feature a flexible combination of a conventional receptacle unit and a functional receptacle in operation to meet user needs and application needs, but the assembly process also features simple engagement and precise positioning.

  • Patent number: 9425533
    Abstract: A rotatable socket assembly, provided in form of a rotatable socket, includes: a side provided with a socket unit and a functional socket, and an adjacent side provided with a flat surface. The rotatable socket starts rotating, when a switch on an active surface of the rotatable socket is pressed to start the driving motor, such that check elements connected to the active end of the driving motor drive the rotatable socket to rotate by a predetermined angle to cause the socket to face upward, thereby facilitating the use of a plug. Alternatively, when the plug is not in use, the switch at a predetermined angle is pressed, such that the check elements connected to the active end of the driving motor drive the rotatable socket to rotate by a predetermined angle to cause the flat surface to face upward and enable the socket to face laterally and get hidden.
