Power connection element esp. terminal block - has collector rail holder to hold rail under force of spring clamp so rail contacts lead inserted into clamp

摘要

The device has an insulating housing (1) and at least one loop-type spring clamp (2). The housing (1) has at least one lead entry opening into which a lead to be connected is inserted. It also has at least one actuation opening into which an actuator tool is inserted to open the spring clamp (2). The housing preferably also has a mounting base for resting on a carrier rail. The clamp spring (2) has a clamp arm with a rectangular or square recess into which the lead to be connected is inserted. It also has a locating arm perpendicular to the clamp arm. The two arms are connected by a bridge. The insulating housing (1) has at least one collector rail holder (12). This is arranged such that a collector rail (13) in the holder (12) lies under the spring force of the clamp spring (2). When an electric lead (4) is inserted, the collector rail 13) makes electric contact, directly or indirectly, with the lead (4).
