Patent ID: 7090520

Claim:
A vehicle mounted electrical outlet box comprising: a case including a pair of plug blade insertion slots configured to receive a pair of plug blades inserted therein; a pair of blade receiver portions electrically connected to an electrical power source of the vehicle, said blade receiver portions configured to press against plug blades inserted into said case through said plug blade insertion slots; a pair of plug blade detection mechanisms configured to detect the presence of each plug blade inserted into each said plug blade insertion slot; a pair of sensor switches, each said sensor switch including ‘on’ and ‘off’ switching contact points that operate in response to detection of the presence of a plug blade by said detection mechanism, wherein said detection mechanisms are located between opposing blade receiver portions, and said contact points of each sensor switch are electrically wired together in a series configuration; and wherein each said plug blade insertion detection mechanism comprises: a pivot lever configured to pivot from the force with which the plug blades are inserted into said plug blade insertion slots, each pivot lever including a pivot shaft pivotably supported by said case, an inclined blade sensor surface that changes the plug blade insertion force to a directional force that intersects the plug blade insertion direction, and a switch operating part driven by the directional force in order to operate a sensor switch, which is mounted to a base plate, when said pivot lever pivots from the directional force, wherein said case and base plate are joined through a connection of mutually indexed recessed notches and projecting tabs are provided on said case and base plate.
