Definitions

  • the invention relates to a contact arrangement for electrical switching devices, in particular electromagnetic switching devices, comprising a cranked contact bridge, which is held in a contact bridge support via a spring plate which is guided against displacement transversely to the direction of movement and which is displaceable against the force of a contact pressure spring in the direction of movement with the spring plate, with fixed Contact parts can be connected via contact pads.
  • a contact bridge is inserted into a window of the contact bridge support and held against displacement in the contact bridge support by the spring plate (DE-GM 1 744 061, DE-AS 1 140 264).
  • the invention has for its object to modify this known contact arrangement in such a way that the contact bridges of the known contact arrangement are modified so that they can also be used for electronic circuits without difficulty, in particular with the possibility of mechanical assembly.
  • This is achieved in a simple manner in that the contact bridge is divided into two in the longitudinal direction and is narrower than the maximum width on both sides in the region of the offset. This makes it possible, in contrast to a further known arrangement (US Pat. No.
  • the contact bridge carrier 1 which is driven by a magnetic drive (not shown in more detail), has a window-shaped opening 2, on the one supporting edge 3 of which the contact pressure spring 4 is supported, which on the other hand rests on the spring plate 5 with frictional engagement.
  • the spring plate 5 is with tab 6 in the direction of actuation Contact bridge carrier 1 guided on this and secured against slipping out.
  • the contact bridge 8 is pressed in between the spring plate 5 and the other support edge 7. It consists of the two contact bridge parts 9 and 10, which were created by longitudinal division of the contact bridge and which can be inserted together between the spring plate 5 and the support edge 7 instead of a conventional one-piece contact bridge, as shown in FIG. 3 in the initial stage.
  • the contact bridge parts 9 and 10 are made narrower through recesses 12 so that the exact width of the contact bridges can be maintained. Otherwise, at least at the bending points, there is fear that the material will widen, so that the contact bridge parts 9 and 10 cannot lie close together, as shown in FIG. 2.
  • the contact pads 13 are, as also shown in FIG. 2, semicircular, so that after insertion of the two contact bridge parts 9 and 10 there is a circular contact pad as a total pad, the parts of which are so close together that the contact pad 14 on the fixed contact part 15 is practically complete is covered without leaving a gap between the two contact pads 13. Outside the contact pads there are insertion lugs 16 which, as shown in FIG.
  • the pent roof-shaped design of the contact pads 13 also allows the contact bridge between the spring plate 5 and the support edge 7 to slide in more easily without the contact bridge getting caught when inserted.
  • the insertion lugs 16 can be provided with bevels, so that the insertion through the inclined surfaces is further simplified without having to go to any trouble.
