Abstract

Ein Zugfederanschluß für elektrische Leiter, mit einem Stromschienenstück (1) und einer schlaufenförmig gebogenen Zugfeder (2), die einen an dem Stromschienenstück (1) anliegenden Schenkel (3), einen etwa senkrecht zum Stromschienenstück (1) orientierten Klemmschenkel (4) mit einer Klemmausnehmung (5) und einen diese beiden Schenkel verbindenden Buckelbereich aufweist, der über einen hinteren Bogenabschnitt (7) in den an dem Stromschienenstück (1) anliegenden Schenkel (3) und über einen vorderen Bogenabschnitt (8) in den Klemmschenkel (4() übergeht, zeichnet sich dadurch aus, daß die Zugfeder (2) so geformt ist, daß in ihrer Ruhestellung der vordere Bogenabschnitt (8) nur in etwa die gleiche Höhe wie der hintere Bogenabschnitt (7) hat.

Figure 00000001
A tension spring connection for electrical conductors, with a busbar piece (1) and a loop-shaped tension spring (2) which has a leg (3) resting on the busbar piece (1), a clamping leg (4) oriented approximately perpendicular to the busbar piece (1) with a Has a clamping recess (5) and a hump area connecting these two legs, which merges via a rear arch section (7) into the leg (3) resting on the busbar piece (1) and via a front arch section (8) into the clamping leg (4 () , is characterized in that the tension spring (2) is shaped so that in its rest position the front arch section (8) has only approximately the same height as the rear arch section (7).
