Definitions

  • the invention relates to a switching device with a contact system, which comprises a box clamp and a contact piece, that firmly embedded and connected with one Head can no longer be lifted, the mechanical and electrical connection of box clamp (1) and contact piece (2) consists of an intimate plug connection.
  • a generic switching device is from DE 295 01 277 U known.
  • a fuse switch disconnector with fuse contacts disclosed as a contact system to the electrically conductive Connection rails are coupled.
  • the contact system is not firmly connected to the housing here, so that it with a clamped conductor can be lifted off.
  • a switching device is from GB-A-2059 191 known.
  • the invention has for its object to provide a switching device to create a contact system of the type mentioned above, the with a simple structure, firmly embedded and with a connected one Conductor can no longer be lifted and low contact resistance guaranteed.
  • a particularly simple embodiment is when the Box clamp via external grooves with the contact piece connected is.
  • FIG. 1 is a front view of a frame clamp 1 and a contact piece 2 composite contact system shown.
  • the box clamp 1 is via grooves 3 on the outside connected to the contact piece 2.
  • the contact piece 2 slots 4 see also FIG 3) into which the box clamp 1 with the engagement of the contact piece 2 in the grooves 3 the box clamp 1 is pushed on.
  • the box terminal 1 has a window 5 with bevels 6 for centering a to be clamped Head on.
  • 5 shows a top view of the box clamp 1 with a bore 7 leading to the conductor connection with a thread is executed.
  • the box clamp 1 can be made from a drawn profile, what a length of any length according to the application allows.
  • FIG Chamber 8 of a switchgear housing 9 fixed in such a way that Contact piece 2 over two opposite edges 9 in grooves 10 of side walls 11 of the chamber 8 is inserted. hereby becomes an optimal anti-twist protection for the contact system guaranteed.
  • the contact system (1,2) is firmly embedded and can no longer be lifted off with a connected conductor.

Claims (3)
