Abstract
A compact slip ring (20), which is particularly adapted for use in small spaces, is adapted to provide electrical contact between a rotor (22) and a stator (21). The improved slip ring broadly includes an electrically-conductive monofilament (24) having one end (28) mounted on the stator and having a distal end (34); a sleeve (25) mounted on and secured to the marginal end portion of the monofilament, adjacent the distal end; and a fiber bundle (26) having a longitudinal axis (39), one marginal end portion of the fiber bundle being recessed in and secured to the sleeve, the other end of the fiber bundle engaging the rotor such that the longitudinal axis of the fiber bundle will be substantially perpendicular to an imaginary line tangent to the rotor surface at the point of contact with the longitudinal axis.
