Abstract:
1. A 12-volt power supply adaptor for use with tractor trailers comprising: an elongated and portable body sized and shaped for being removably positioned between a tractor trailer and an associated trailer hitch, said body having a centrally registered longitudinal axis and a pair of axially opposed end portions wherein one said end portions is rotatably articulatable about the axis for assisting an operator to adjustably position said body in confined areas located between the tractor and the trailer hitch respectively, said body including a pair of diametrically offset L-shaped arms protruding outwardly therefrom in such a manner that said L-shaped arms can be rotated along independent arcuate paths extending along a 360 degree circumference extending parallel to the axis, another said body end portions and said L-shaped arms defining a plurality of respective electrical contacts for receiving a corresponding male receptacle associated with an auxiliary power device so that the auxiliary power device can be directly mated to said body exterior of the tractor trailer while drawing power from a tractor trailer power supply source located within an engine compartment thereof, said body further including a flap directly conjoined to said another body end portion and repeatedly pivotal between open and closed positions for sheltering said electrical contact associated with said another body end portion during non-operating conditions; a plurality of conductive leads having opposed end portions directly mated to said electrical contacts and housed within said body; and means for regulating power distribution to said electrical contacts such that the power distribution can be automatically disconnected from said body when the tractor trailer power supply source drops below a minimum threshold level, said minimum threshold level being set at 12-volts.
