Abstract
A screw (14) axially abuts an oblique surface (10a) of a clamping member (10) to drive that member at a right angle to the axis of the screw (14) to clamp a conductor (6) against a conductive terminal member (4a) within an electrical switching device. A coiled band spring (12) has the coiled ends received within recesses (10a) in the opposite surfaces of a clamping member (10) and the central portion of the band spring looped around a supporting member (8) for the screw (14) to bias the oblique surface (10a) into engagement with the end of the screw (14). The band spring (12) is received within shallow grooves (8b and 10b) in the supporting and clamping members to cooperate with the grooves in restricting movement of the clamping member (10) to linear movement at right angles to the axis of screw (14). The restrictive and guiding functions of the band spring and grooves can be supplemented or substituted for by the configuration of a surrounding housing for the connector members.
