Electrical connector for an electromechanical device

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.
