<p>An improved plug assembly for providing electrical power to a device from a plurality of power sources having different receptacle geometries is disclosed. In a first embodiment, first and second pivotally movable plugs are provided in a housing, each plug having an electrical contact for movement into and out of engagement with first and second respective contacts of a device, and a control mechanism for permitting only one of the plugs to be pivoted into engagement with a corresponding contact at a time, thus allowing only one plug to carry electric current at one time. The control mechanism may comprise first and second cams attached to the first and second plugs, respectively, and a cam follower slidably positioned therebetween. The first and second plugs may comprise a US/European style connector and a UK connector, a two prong plug and a three prong plug, two polarized plugs, or any other style connectors or plugs to meet the plugging needs of a user. The dual plug assembly may be attached to a combination charger and power source for an electrically powered device having a removable battery pack or may be used on an extension cord or directly on a power cord of an electrically powered device. The assembly may include a pivoting panel on a top cabinet which holds an output connector to which a mobile phone may be attached. The assembly may alternatively include a coiled electrical cord upon a wind-up button. In an alternative embodiment, the assembly may include one or more female receptacles for accepting connectors of varying geometries.</p> |
