Definitions
- the invention relates to a tension spring connection for electrical conductors, with a Busbar piece and a loop-shaped tension spring, which one the leg resting on the conductor rail, one approximately perpendicular to the conductor rail oriented clamping leg with a clamping recess and one of these two Has leg connecting hump areas, the rear arch section in the leg resting on the conductor rail and over a front one Arc section merges into the clamping leg.
- the tension spring has a shape in which the front arch section, which merges into the clamping leg, in the rest position the tension spring is significantly higher than the rear section of the arch, which in the the leg resting on the busbar merges (DE 27 06 482 C2, DE 295 14 509 U1).
- This has advantages with regard to the actuation of the tension spring connection, since one particularly from the front also with an actuating device the direction of insertion of the conductor on the front arc section with a simple screwdriver or the like, however, this design of the tension spring has the tension spring connection in the rest position the tension spring has a relatively large overall height, which is used in numerous applications may be undesirable in the context of miniaturization of switchgear can.
- a tension spring connection with a reduced overall height is already known.
- the rear arch section is shaped so that it is part of its arch to below one by the extension of the adjacent to the busbar Leg defined system level is lowered and accordingly the busbar has a depression or recess in this area, in which the lowered Part of the rear arch is arranged.
- the present invention has for its object a tension spring connection to create with reduced height, which is easy to manufacture and the usual Insertion depth guaranteed for the electrical conductor.
- the solution according to the invention consists essentially in the tension spring being so is shaped that in its rest position, the front arc section only approximately has the same height as the rear arch section.
- An embodiment is preferred where the front arch section is at most the height of the rear arch section Has.
- the tension spring connection includes a busbar piece 1, which in particular multipole connections also a piece of sheet metal extending over several poles can be.
- a busbar piece 1 which in particular multipole connections also a piece of sheet metal extending over several poles can be.
- One is essentially loop-shaped on the conductor rail piece 1
- tension spring 2 is arranged, which abut the busbar 1 Leg 3 and one essentially perpendicular to the conductor rail piece 1 oriented clamping leg 4.
- In the clamping leg 4 there is one Clamping recess 5 through which an end section of the busbar piece 1 can pass through and which defines a clamping edge with which an inserted electrical conductor 6 on the corresponding surface of the conductor rail piece 1 can be clamped.
- the tension springs 2 are on the busbar piece 1 arranged and the electrical conductors 6 are on the lower surface of the busbar piece 1 clamped. It is easily possible to use the tension springs also to be arranged on the underside of a track piece and the electrical Then clamp the conductor on the upper surface of the conductor rail piece.
- the tension spring 2 has a hump area that connects the legs 3 and 4 to one another.
- the tension spring 2 has a rear arc section 7 with which the Hump area merges into the leg 3 resting on the conductor rail piece 1, and a front arc section 8 with which the hump area of the tension spring merges into the clamping leg 4.
- the tension spring is now shaped so that in the rest position of the tension spring, in the front arch section has its maximum vertical extent, this front arch section 8 now only has approximately the height of the rear arch section 7.
- the front arch section 8 has a maximum of Height of the rear arch section 7. This leads to a significantly reduced Height of the tension spring connection in the rest position and thus meets the requirements which represents the miniaturization of such switchgear.
- the conductor rail piece 1 on its contact surface for the electrical conductor 6 over the entire extent remains flat, it does not only remain with a simple manufacture of the conductor rail piece 1, but also with the previous full insertion depth for one electrical conductor.
- the production of the tension spring 2 itself is complicated practically not thanks to the new design.
- the rear arch section 7 and the front arch section 8 through a deeper indentation 9 are connected to each other.
- the indentation 9 can in particular to Overexpansion protection can be used and also makes operation easier the tension spring with an operating tool adapted to the new tension spring shape.
