Abstract
A ball contact slip ring assembly for conducting electrical signals between two relatively rotating structures, and which is particularly suited for use in gimbaled inertial guidance systems. The assembly includes a slip ring disposed on one structure and a brush associated with the ring on the other structure. The slip ring is provided with a groove which extends around the outer circumference thereof and the slip ring may be composed of a relatively soft noble metal. The brush comprises a pair of spring-biased, resilient arms spaced from one another, each arm having an electrically conductive ball secured thereto which is adapted to ride within the groove of the slip ring and accommodate diverse motion while maintaining a consistent electrical contact. The balls may be composed of a low friction, corrosion resistant material while the brush may be composed of a suitably resilient material with high electrical conductivity which is different from that of the ball and which applies the proper loading to the balls. Where a plurality of such assemblies are required, adjacent brushes and slip rings are separated by insulation material in a molded or laminated housing, and the brushes …
