Abstract
Abstract A power supply is incorporated in a male plug assembly at one end of a line cord. The male plug assembly is provided with means for preventing said assembly from abutting against a wall when said male plug is received in a female receptacle in said wall. The aforesaid means maintains an air space between the wall and the assembly thereby enabling convection air currents to dissipate the heat produced by the power supply.

Total Claims: 12
Claim 1
Independent Claim
203 words
In combination: a power supply, comprising means for converting an input voltage to an output voltage having a different phase, frequency or voltage therefrom, said power supply also including at least two generally parallel spaced-apart elongated blades adapted for being at least partially received in a wall-mounted female receptacle which establishes said input voltage between said blades for energizing said power supply and a line cord having at least two conductors between which said output voltage from said power supply is established; a body of dielectric material within which said power supply including said converting means is enclosed, said blades protruding from a surface of said body and said line cord protruding from said body at a location remote from said surface; and, dielectric means extending from said surface of said body in the same general direction as said blades and enclosing part of the length of each blade so that an exposed length of each blade extends beyond said dielectric means, said exposed length of the blades being of sufficient length for receipt thereof in said female receptacle, said dielectric means spacing said surface of said body from the wall-mounted receptacle to enable convention air currents to dissipate heat from said body.
