<p>Busbar contact-making means with bar thickness compensation for mechanically fastening and making electrical contact with an electrical appliance in combination with a conductor bar of a first thickness or a conductor bar of a second thickness which is smaller than the first thickness, on which the busbar contact-making means can be locked, comprising: a basic body (10), which comprises a base (12) with an opening (122) and, spaced apart therefrom, a mating piece (14), which is arranged substantially parallel to the base (12), wherein the distance is appropriate for a conductor bar of the first thickness; a contact element (20), which rests at least partially in the opening (122) in the base (12) and to which a force is applied in the direction of the mating piece (14); a spacer piece (30), which is suspended on the mating piece (14) of the basic body (10) in such a way as to be pivotable out of an initial position, wherein the pivot axis (18) is opposite the opening (122) in the base (12), and which has a first eccentric lever (32) and a second eccentric lever (34), spaced apart therefrom; characterized in that the spacer piece (30) assumes the initial position, with the application of a spring force, in a state in which it is unloaded by a conductor bar, wherein in the initial position, both the first eccentric lever (32) and the second eccentric lever (34) protrude into the gap between the base (12) and the mating piece (14), and the free lever edge of the first eccentric lever (32) narrows the gap between the base (12) and the mating piece (14) in such a way that the clear width (l1) of the gap is smaller than the first thickness (d1) but greater than the second thickness (d2), and the free lever edge of the second eccentric lever (34) narrows the gap between the base (12) and the mating piece (14) in such a way that the clear width (l2) of the gap is smaller than the second thickness (d2), wherein the first eccentric lever (32) is positioned in front of the second eccentric lever (34) in the direction in which it is pushed onto a conductor bar.</p> |
