Abstract
A plug assembly includes a main plug member having a pair of main plugs, a pair of elongated cylindrical apertures and a pair of elongated rectangular apertures, and a plug adapter member having a pair of cylindrically shaped terminals and a pair of elongated cylindrical first apertures disposed on one side wall and a pair of rectangular shaped terminals and a pair of elongated cylindrical second apertures disposed on other side wall thereof, the cylindrical shaped terminals and rectangular shaped terminals connecting to the first and second apertures, respectively, whereby the plug assembly enables the selective use of either one terminals or other terminals depending upon high voltage or low voltage usage.
Claims8
An electrical plug assembly which accommodates multi-voltages for use in conjunction with an electric appliance, which comprises:
- an electrical plug member attached to said electric appliance, said electrical plug member including,
- a pair of cylindrically shaped main plugs mounted to a side wall thereof,
- a pair of cylindrically shaped main apertures disposed on said side wall, and
- a pair of elongated rectangular shaped apertures disposed on said side wall and inside of said pair of cylindrically shaped main apertures, said main plugs being located normal to said main apertures and said elongated rectangular apertures for preventing an electrical connection therebetween;
- a plug adapter member assemblable with and disassemblable from said electrical plug member, said plug adapter member including,
- a round body member having a cylindrical configuration and first and second side walls disposed on opposing sides thereof respectively
- a first cover and a second cover attached to said first and second side walls, respectively
- a pair of cylindrically shaped terminals
- mounted to said first cover,
- a pair of cylindrically shaped first apertures disposed on said first cover, said pair of cylindrically shaped terminals and said pair of first apertures being located normal to each other for preventing an electrical connection therebetween,
- a pair of elongated rectangular shaped terminals mounted to said second cover,
- a pair of cylindrically shaped second apertures disposed on said second cover, said pair of elongated rectangular shaped terminals being located normal to said pair of cylindrically shaped second apertures for preventing an electrical connection between said pair of rectangular-shaped terminals and said pair of cylindrically-shaped second apertures, wherein assembly of the plug adapter member with the electric plug member forms a composite structure enabling the selective use of either the cylindrically shaped terminals or the elongated rectangular shaped terminals depending upon high voltage or low voltage usage.
