Definitions

  • the invention relates to an electrical switchgear, in particular an electromagnetic switchgear, with a contact arrangement consisting of held in the windows of a contact bridge support via a spring plate that is secured transversely to the direction of movement of the contact bridge support against shifting relative to the contact bridge support and guided in the direction of movement of the contact bridge support, against the force of a contact pressure spring parallel, movable in the longitudinal direction, insertable in the direction of movement with the spring plate and separated by a separating contact bridges, which can be connected to fixed contact parts.
  • the contact bridges are inserted into lateral incisions in the spring plate transversely to their longitudinal direction, as long as the spring plate is not yet in the window-shaped opening.
  • the contact bridges must be elastically bendable in order to be able to introduce center elevations on the contact bridges into adapted recesses in the spring plate in order to prevent longitudinal displacement of the contact bridges during operation. This bracket limits the mobility of the contact bridges against each other.
  • the invention has for its object to provide an arrangement of the type mentioned above, which allows free movement of the contact bridges against each other with a simple structure and easy installation, the disadvantages of a further known arrangement (DE-OS 31 36 354) to be avoided, namely that when welding the diagonally opposite contact pads of different contact bridges a connection of the fixed contact parts can remain with the fixed contact parts when opening the contact arrangement like a pair of scissors via the central parts of the contact bridges.
  • the separating web runs over the entire outer contour of the spring plate.
  • the contact bridge support has recesses adapted to the separating webs in the narrow window boundary walls.
  • the contact bridges in the area of the contact pads are made wider in the direction of the separating web and have projections that extend into correspondingly adapted recesses in the other contact bridge.
  • the pair of contact bridges can only be inserted into the contact carrier in the "correct" position. If lugs and recesses lie on one long side of the contact bridge with mirror symmetry to the center of the contact bridge, the adjacent contact bridges can be designed in exactly the same way.
  • the switching magnetic part 1 which is attached to the contact bridge carrier 2 made of plastic, is shown.
  • the contact bridge support 2 there are window-shaped openings 3 in which spring plates 5 which can be displaced in the windows against the force of the contact pressure spring 4 are guided.
  • the spring plates 5 rest against the narrow window boundary walls 6.
  • the spring plates are adapted to the cranking of the contact bridges 7 and have guide lugs 8 which extend beyond the windows, and separating webs 9 which, when the contact bridges are inserted, protrude between the two contact bridges 7, as is the case in the right window of the arrangement 1 is shown.
  • the separating webs 9 protrude into correspondingly adapted grooves 10 on the narrow window boundary walls 6, so that the spring plate rests snugly on these boundary walls.
  • the contact pressure spring 4 ensures the concern.
  • guide pins 11 are formed on the inside of the spring plate made of plastic.
  • the contact bridges 7 have widenings 13 in the area of the contact supports 12, so that the entire area of the contact supports for the fixed contact parts 14, which are shown schematically in FIG. 1, can be used while leaving the space between two contact bridges for the separating web 9. In the area of the widening lugs 15 and 16 are formed, which can protrude into corresponding recesses 17 and 18 of the opposite contact bridge.
  • the interlocking of lugs and recesses has the further advantage that a displacement of the individual contact bridges against one another in the longitudinal direction is essentially impossible during operation. In addition, mechanical insertion is made considerably easier.
