Abstract
Abstract An electrical connector for an electromechanical device is provided. The connector includes a housing having a first and second ends and an axis extending longitudinally through the housing. The housing is adapted to be connectable to a surface, and the electromechanical device is disposable in the housing. A rotatable portion having first and second ends is rotatably connected to the housing. The second end of the rotatable portion is positioned adjacent to the first end of the housing along the axis. A fastener fastens the rotatable portion to the housing, and the rotatable portion is adapted to turn about the axis. First and second contacts are axially aligned with and radially disposed from the axis. One of the contacts are disposed on the second end of the rotatable portion and the other on the first end of the housing. The first contact is biased by the fastener into slidable electrical contact with the second contact.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
247 words
An electrical connector for an electromechanical device, comprising: a housing having first and second ends and an axis extending longitudinally through said housing, and being adapted to be connectable to a surface bore, said electromechanical device being disposable in said housing; a rotatable portion having first and second ends and being rotatably connected to said housing, said second end of said rotatable portion being positioned adjacent to said first end of said housing along said axis; means for fastening said rotatable portion to said housing, said rotatable portion being adapted to turn about said axis; a first and second set of radially spaced, electrically conductive contacts being axially aligned with and radially disposed from said axis, said first set of contacts being disposed on said second end of said rotatable portion and said second set of contacts being disposed on said first end of said housing, wherein said first set of contacts is biased by said fastening means into slidable electrical contact with said second set of contacts to deliver electrical energy to said electromechanical device; said first end of said housing defining a plurality of annular recesses being radially spaced from and coaxially disposed about said axis, said second set of contacts being disposed in said annular recesses; a pair of circular bands of elastomeric material, each band having a circular cross sectional area and being disposed in said annular recesses; and wherein said second set of contacts are positioned between said pair of circular bands.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
22 words
An apparatus, as set forth in claim 1, wherein said rotatable portion is adapted to turn at least 360° about said axis.
Claim 4
Dependent Claim
21 words
An apparatus, as set forth in claim 2, wherein each contact is formed in a ring coaxially disposed about said axis.
Claim 5
Dependent Claim
33 words
