Definitions

the present invention relates to a tension spring connection for electrical conductors the preamble of claim 1.
a tension spring connection is known for example from DE-OS-39 11 459.
the The spring force of the tension spring cannot be increased arbitrarily, so that to increase the surface pressure minimizing the printing area remains as the only alternative.
connection should be gas-tight.
the present invention is therefore based on the object of a tension spring connection of the generic type so that the surface pressure in Connection area between the tension spring or the busbar and the conductor with unchanged spring force of the tension spring, even with the smallest tension spring connection elements, is as big as possible.
the busbar a sharp-edged area on the side facing the conductor has, which runs transversely to the longitudinal axis of the conductor and which is also digs into the conductor when pressed against it.
This sharp-edged design can be achieved, for example, in that the busbar has a tongue-like punching, the free end in Is bent towards the conductor, which results in a sharp clamping edge.
this clamping edge the tongue is offset in relation to the clamping edge of the window opening is.
a tension spring connection which consists of a tension spring 1 and a Busbar 4 exists.
the tension spring 1 is loop-shaped and has a clamping leg 2 and a contact leg 3. On this, the busbar 4 is fixed, which in a window cut 5 provided in the clamping leg 2 passes.
a clamping edge 9 is formed through which a pin-shaped conductor 11, the as can be seen from FIG. 3, can be guided through the window cutout to the Busbar 4 is pressed.
the busbar 4 has a pronounced tongue 6, which is under a certain Angle in the direction of the end region 8 of the clamping leg 2 inclines and whose free outer edge also forms a clamping edge 10, which is in the use position, that is, with the conductor 11 inserted, on the clamping edge 9 opposite Side of the conductor 11 is supported and there due to the clamping leg 2 applied spring force, which presses the conductor 11 against the clamping edge 10, digs in.
crank angle of the end region 8 and the angle of inclination of the tongue 6 are the to determine the respective requirements, which depend on the conductor cross-section.
