Abstract

Bei dieser Zugfederklemme ist die untere Begrenzung der Durchtrittsöffnung (6) im Klemmschenkel (5) der Zugfederklemme (1) durch zum freien Ende des Klemmschenkels hin konvergierende Schrägen (7) leiterzentrierend ausgebildet, so daß automatisch beim Anschließen eines einzelnen oder mehrerer Leiter in dieser Verjüngungszone auf der Unterseite der Stromschiene (2) eine Leiterzentrierung und ― kompaktierung erfolgt.

Figure 00000001
In this tension spring clamp, the lower limit of the passage opening (6) in the clamping leg (5) of the tension spring clamp (1) is designed to be conductor-centered by bevels (7) converging towards the free end of the clamping leg, so that automatically when a single or several conductors are connected in this tapered zone A conductor centering and compacting takes place on the underside of the busbar (2).
