Low profile rotatable electrical plug

A low profile rotatable electrical plug comprising:

• a first set of N electrical conductors;
• a second set of N electrical conductors, at least one of said first and second sets of electrical conductors comprising a set of concentric annular conductors;
• a first support plate having a face configured to carry said first set of electrical conductors;
• a second support plate having first and second opposing faces, said first face being configured to carry said second set of electrical conductors;
• means for rotatably connecting said first and second support plates such that each conductor in said first set rotatably and electrically contacts a different one of the conductors is said second set;
• a power cord having N electrical conductors, each electrical cord conductor being electrically connected to a different one of the conductors in said first set, said power cord being affixed with respect to said first support plate;
• N conductive prongs extending from and fixed with respect to the second face of said second support plate for rotation with the second support plate, each conductive prong being electrically connected to a different one of the conductors in said second set;
• and
• locking means for releasably locking the position of said first support plate with respect to said second support plate.

A low profile electrical plug, comprising:

• a first housing portion having a front face, a back face, and a center aperture extending between said front and back faces;
• a second housing portion having a circular top and an annular sidewall wall extending from said circular top, said annular side wall including a bottom surface adapted to engage the back face of said first housing portion;
• means for connecting said first and second housing portions to form an integral housing having an interior compartment defined by said circular top, said annular side wall and the back face of said second housing portion;
• a plurality of concentric annular conductors;
• a plurality of elongated conductive springs;
• a first support plate fixedly mounted in said housing interior compartment, said first support plate having a face with a plurality of concentric annular grooves formed in different planes thereof, each annular groove being adapted to support a different one of said annular conductors;
• a second support plate mounted within said housing compartment for rotation relative to said first support plate, said second support plate having first and second opposing faces, said first face being configured to carry said conductive spring conductors such that each conductive spring rotatably and electrically contacts a different one of said annular conductors, said back face including a reduce diameter portion which extends through and rotatably engages the center aperture in said first housing portion;
• a power cord having a plurality of electrical conductors, each electrical cord conductor being connected to a different one of said annular conductors, said power cord being rigidly fixed to said first plate and extending through said housing side wall for electrical connection to a remote device;
• and
• a plurality of electrically conductive prongs extending from the second face of said second support plate and through said center aperture for rotation with the second support plate, each electrically conductive prong being electrically connected to a different one of said conductive springs.
