Definitions

  • the invention relates to a support device for a busbar according to the introductory part of claim 1.
  • the invention relates to a busbar for Use with such a carrying device as well as on a Coupling device for connecting such busbars.
  • A is a carrying device in here Known type for a busbar known.
  • a holder or bracket that is made using a screw is fixed.
  • the bracket has a C-shape in cross section, whereby the legs or arms at their free ends to form Locking projections are angled inwards. This angled Ends engage in grooves in the plastic rail.
  • the coat hanger is obviously made of metal, since he is with a Earthing strip is in electrical contact, and in the case of one a fixed latching connection with the busbar is a subsequent one Removing the bracket from the power rail is relatively difficult. If the angled ends are angled less, i.e. would be less strong in the manner of barbs, conversely, the fixation of the conductor rail in the bracket would not be reliable.
  • the object of the invention is to provide a carrying device of the type mentioned at the beginning, which without the aid of a Tool quickly and easily both stably mounted as well can be dismantled, even when live standing busbar without fear of a short circuit is.
  • Another object of the invention is to provide a Conductor rail for cooperation with such a carrying device, which such a quick, easy attachment or removal the carrying device - without risk of short circuit - allowed, and which also has a connection in the form of a coupling device to at least one more track in also faster and easily made possible without the aid of a tool.

  • the cover caps in general are conical and in the area above and below the bundle of the insulating piece two opposite each other Have threaded holes into which a threaded end of the contact pins can be screwed in. If the arms are springy with the help of a through the threaded holes the other cap inserted pin-shaped leg having tool are pressed together so that the To release snap connection, so that the other cap is detachable from the insulating part.
  • the Contact pins wear at least one contact sleeve, which the wall of the bore of the metal profiles with the contact pins connects in a leading way.
  • the contact sleeve from several cambered, circular, springy, metallic Slats exist, each end in a circular Pass over the federal government, which is interrupted by a slot is, whereby the contact sleeve can be snapped onto the contact pin is.
