Patent ID: 7914291

Claim:
A rotatable electrical connection comprising: a) a first power transfer coupling comprising a body encompassing first and second conductive rings and an electrical connector for providing electrical connection between said rings; b) a connector body including first and second conductive tubes; c) a second power transfer coupling comprising a body encompassing first and second conductive rings and an electrical connector for providing electrical connection between said rings d) said first power transfer coupling placed about a first end of said connector body such that the first conductive tube is in electrical communication with the corresponding first ring of said first coupling and the second conductive tube is in electrical communication with said corresponding second ring of said first coupling; e) said second power transfer coupling placed about a second end of said connector body such that said first conductive tube is in electrical communication with said corresponding first ring of said second coupling and said second conductive tube is in electrical communication with said second ring of said second coupling in a manner such that each ring is free to rotate about a surface of a corresponding conductive tube and such that said first power transfer coupling and said second power transfer coupling can freely rotate relative to each other.
