Abstract

Power outlets adapted for installation within an enclosure are provided. Power outlets are provided having a safety interlock adapted to prevent the creation of a hazardous condition within the enclosure as a result of the continued operation of an electrical device within the enclosed space. The safety interlock may include current limiting circuitry and hardware, hazard sensing devices interconnected with such current limiting circuitry and hardware or other circuit breaker switches, and combinations of such safety interlocks. The power outlets may also be adapted for installation within a movable enclosure, such as, for example, a drawer.

12. The power outlet assembly of claim 11, wherein the rigid elongated arms collectively define an internal channel within which the flexible electrical interconnector is disposed and at least partially enclosed.

13. The power outlet assembly of claim 12, wherein the flexible electrical interconnector and rigid elongated arms are configured such that when the power outlet is proximal to the power source along the predefined path, the flexible electrical interconnector and the elongated arms are bent into a single U-shape having a first end interconnected with the power source and a second end interconnected with the power outlet and having a bend radius at least equal to the specified minimum bend radius, and wherein the U-shape has a folded length approximately half the length of the defined range of motion of the power outlet.

14. The power outlet assembly of claim 1, wherein the first rigid elongated arm is pivotally joined to the power source through a joining armature that extends the pivot point away from the body of the power source.
