Fixing terminal and the modulus of the electrical connection to a circuit breaker withdrawable

摘要

The invention relates to a fixing terminal (40) for an electrical switchgear apparatus for cutting by pulling out axially, in particular for a withdrawable circuit breaker (20), comprising a protruding part (42) extending along an axis (e - e) intended to be placed parallel to the axis of the drawout, defining at its outer surface of the side of its free end a contact surface (44) intended to cooperate with the fixing jaws (55) of a draw-in grip (50), the plug-in jaws (54) are intended to cooperate with pins with a terminal of the electrical contacts (22). The contact surface (44) is the case of a sector of a cylinder of axis (a - a) perpendicular to the axis (e - e) of the projecting part (42), on the opening angle greater than 180degre and adapted to form a pivot for the rotation of the clamp (50) about the axis (a - a) of the cylinder. The application: multipole circuit breakers withdrawable.
