BUSBAR CONTACT-MAKING WITH BAR THICKNESS COMPENSTAION

摘要

The invention relates to a spacer (10) for matching a gap in a spring hook (30) to the thickness of a conductor bar (50), which spacer can be fitted on the spring hook (30) in such a way that it is capable of rotating about an axis of rotation (60) and has, in order to bear against a conductor bar (50), at least one convexly shaped region (11), wherein the axis of rotation (60) is located on the side of the opening of the convex region (11) behind said convex region (11); and furthermore a spring hook (30) with a hook limb (31) on the device side which is fixed to the device (70) and at least one clamping hook limb (32), which is designed to be substantially parallel to the device-side hook limb (31), for absorbing a clamping force and at least one connecting web (33), which connects the two hook limbs (31, 32), and with a device (34) for the rotatable arrangement of a spacer (10), wherein the axis of rotation (60) of the device (34) for the rotatable fixing of the spacer (10) is arranged on the clamping hook limb (32).
