ABSTRACT:
A rotatable electrical plug and power cord for mating with a conventional electrical outlet comprises a housing first portion and a housing second portion rotatably coupled to the housing first portion. The housing first portion carries first and second electrically conductive outlet prongs extend from the housing first portion a sufficient distance to permit the prongs to engage into an electrical outlet. The housing second portion is connected to the proximal end of a power cord such that the power cord can rotate relative to the prongs. The power has a pair of electrical conductors extending between its proximal and distal ends. A flexible conductor means electrically interconnects the power cord conductors with the respective prongs and permits the housing first portion to rotate relative to the housing second portion without imparting forces on the power cord conductors. The flexible conductor means may comprise a pair of multiwire conductors, each of which extends between a power cord conductors and a respective prongs. The multiwire conductors are substantially more flexible than the conductors traditionally used in a power cord and, as a result, are able to withstand the bending and twisting forces imparted on them during rotation of the housing portions relative to each other.
