Charger plug with improved package
DCFirst Claim
1. A charger plug capable of connecting with a two or three receptacle power source to convert 120V input power received from the power source to DC output power, the charger plug being electrically connectable to a rechargeable electronic device via a power cord for providing the DC output power thereto, the charger plug including a housing, the charger plug comprising:
- first and second separate blade members secured within the housing so as to have prong portions of the blade members positioned in order to extend in a first direction from a front wall of the housing, the prong portions adapted to be received in the receptacle openings of the power source;
the charger plug including a DC connector having an aperture adapted to removably receive a corresponding power cord plug end for transmitting DC power to the rechargeable electronic device;
the charger plug housing forming a) a charger plug face area defined by the front wall b) an outer profile defined by a perimeter of the front wall and defined by a plug body extending rearward from the front wall and c) a rear end opposite the front wall;
the charger plug configured to be capable of plugging into a standard wall outlet and further;
i) being sized so that the charger plug housing comprises a longitudinal length extending between the front wall and the rear end and the longitudinal length is equal to or less than 2.0 inches andii) the outer profile having no interference with an adjacent receptacle of the power source located on all sides of the first receptacle when a like charger plug is mounted in all available orientations in any of the other receptacles,so that when space is limited by an obstacle adjacent or in front of the power source the charger plug is capable of being conveniently mounted to one of the receptacles, the power cord plug end may be conveniently received by the DC connector and the power cord plug end can be conveniently removed from the DC connector while leaving the charger plug connected to the receptacle.

Abstract
A reduced plug-size charger plug for power conversion is disclosed utilizing a pair of blades that are slidably mounted into a charger housing, obviating the need for insertion molding. To promote and maintain electrical contact while minimizing package size and charger plug cost, a pair of spring contacts are provided for electrically connecting the blades with internal circuitry.
