Definitions

  • the present invention relates to a conductor connection, in particular for high-current terminals, with a busbar, a clamping body surrounding it, defining a conductor receptacle, and a clamping member.
  • the busbar enters the clamping body from one side, while the conductor to be connected from the other, the so-called conductor insertion side, into which the clamping body is inserted.
  • the conductor and the end of the conductor rail concerned are then fixed to one another within the surrounding clamping body with a clamping member, normally a clamping screw equipped with a pressure piece.
  • the present invention has for its object to provide a wire connection of the generic type which ensures both a very simple handling during wire insertion, as well as at the same time heat up mun g s of the clamping body at the AC system avoids.
  • the solution according to the invention is that the end of the conductor rail is bent back and only the back bend, from the conductor insertion side, is arranged in the clamping body.
  • This design which is only insignificantly more expensive to manufacture the conductor rail, solves both the problem of handling and that of heating. Thanks to this configuration, the current that enters the clamp body from the conductor via the conductor insertion side also flows out of the clamp body on the same side, and no longer, as previously, on the other clamp body side, on which the busbar has hitherto been used Clamping body emerged. This results in a compensation of the electromagnetic effect on the clamping system. So even if ferromagnetic materials are used, the end result is no longer an electromagnetic induction current.
  • the clamping system is subject to significantly reduced heating even when operated with alternating current of relatively large current intensities, and it also has a significantly reduced volume resistance.
  • the conductor connection can therefore either be dimensioned less overall than before, or it can be subjected to higher electrical loads while maintaining the previous dimensions.
  • the retention of ferromagnetic materials, especially steel, ensures high mechanical stability and the possibility of permanently applying high clamping forces.
  • the drawing shows such a conductor connection with a sectional view of the clamping body.
  • the conductor connection includes a clamping body 1, which is designed as a steel bracket closed by corresponding bends. At the top, a clamping screw 2 is screwed into the clamping body 1 as a clamping member, the clamping action of which is to be reinforced by a pressure piece 3 assigned to it.
  • a busbar 4 which cooperates with the clamping member 1 end Umbie- un g a g 5 has.
  • backbend is to be understood as any kind of rearward-facing angulation at the end of the busbar.
  • the Reverse bend may be formed either by an actual bending of the rear end of the busbar, as well as by attaching a corresponding W domestic kels at the end of a straight, non-bent current bar.
  • the clamping body 1 also defines a receptacle for the conductor 6 to be connected.
  • This conductor 6 is always inserted into the clamping body 1 from a certain side, the so-called conductor insertion side.
  • the arrangement is such that the back bend 5 of the busbar 4, and only this back bend 5, points from the conductor insertion side into the clamping body 1.
  • the course of the current resulting from this configuration after the conductor connection has been activated is illustrated by arrows in the drawing. It can be seen that, thanks to this configuration, the current flowing from the conductor into the conductor rail flows out of the clamping body 1 on exactly the same side on which it also flows.
  • the view of the drawing also shows that handling when the conductor connection is made is extremely simplified. Any threading of the conductors to be connected before the connection is omitted.
  • the end of the conductor to be connected can be placed on the back bend 5 of the busbar 4 and then jointly on both parts, based on the busbar 4 practically from the inside, the clamping body 1 can be pushed onto the two parts and the clamping can then be carried out.
  • the bending process at the busbar ends can expediently be combined with a machining process with which a conductor pull-off protection is formed, e.g. in the form of a corrugation of the conductor rail surface or a clamping hook on the front edge of the conductor rail.
