Definitions
- the present invention relates to a tension spring connection for electrical conductors according to the preamble of claim 1.
- Such a tension spring connection is known for example from EP 0 597 190 A.
- the clamping leg runs Tension spring in a slightly curved course that extends over the area of the window opening and in the same way over that on the underside of the window opening extends the following end region.
- an edge of the lower reveal is at a small angle to the inserted one Conductor, which leads to a very small indentation of the conductor and thus only leads to a slight clamping of the conductor.
- DE-A 35 04 317 shows a clamp for electrical conductors with a tension spring, which has a reveal in a window-like interruption, one edge of which is also is at a small angle to the inserted conductor. Opposite this Edge is a curved support tab of the busbar arranged to provide an additional To ensure backup.
- the present invention is therefore based on the object of a tension spring connection of the generic type so that the surface pressure in the connection area between the tension spring and the busbar and the conductor unchanged spring force of the tension spring, even with the smallest tension spring connection elements, is as big as possible.
- the task is carried out by a tension spring connection with the characteristics of the characteristic Part of claim 1 solved.
- clamping takes place both between the clamping leg of the tension spring and the conductor by means of a clamping edge that clearly digs into the conductor and also additionally the further also digging-in clamping edge on free end of the tongue of the busbar.
- the clamping edge on the tongue is in proportion offset to the clamping edge on the reveal of the window opening.
- a tension spring connection which consists of a tension spring 1 and a Busbar 4 is made.
- 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.
- 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.
