Definitions

  • the present invention relates, in general, to adaptors for connecting plugs to different types of power outlets, and, more particularly, to an adaptor which has an improved structure such that a plug of an electrical device, which is manufactured and sold in a particular country or area, can be connected to different types of power outlets in other countries or areas, and such that the plug of the electrical device can be easily coupled to and removed from the adaptor.
  • Background Art
  • the electrical devices that are manufactured and sold in almost all nations in the world are designed such that they can be operated using 110V or 220V power.
  • plugs that connect the electrical devices to power supplies, that is, to the power outlets are designed according to the standard of the corresponding country to correspond to the power outlets in that country.
  • the plug-in adaptor of US Patent No. 6,749,451 can be selectively connected to plug-in systems of several countries.
  • the electric adaptor of WO 87/04570 includes five kinds of plug systems and a socket having a rotatable body, so that it can be used with various international standard plug systems by rotating the body.
  • the plug of Japanese Laid-open Publication No. Heisei. 04-033280 has a main body, one surface of which is planar. Several types of plugs and terminals are provided on the sidewall of the main body.
  • a socket is rotatably provided through the central portion of the main body, which has a triangular shape.
  • 229,692 includes the electric plug, which is removably coupled to the casing and is movable between a mounting position and an operating position, a mounting means, and the locking means, which is provided in the casing and holds the plug to maintain the operating position of the plug.
  • Each conventional technique in which the above-mentioned construction is used includes the socket, which is mechanically and electrically connected to a plug of a desired electrical device, and the plugs, which are connectable to various types of power outlets of several countries or areas, thus making it possible to connect the desired electrical device, which is manufactured to correspond to the power outlet of the corresponding country, to various types of power outlets of several countries or areas.
