Definitions

  • the embodiment according to the invention is a coupling gear, in which both the hinged armature is pressed into its support and a reset of the hinged armature and thus also of the contact carrier is effected by means of a single spring.
  • the return spring does not execute a linear movement in its own axis, but rather a swiveling movement.
  • the direction of force changes with respect to the hinged armature on one side and to the contact carrier on the other side, so that the restoring force acting on the contact carrier can follow a sine function, as a result of which savings can additionally be made in the magnet system.
  • the fact that the restoring force from one position of the contact carrier to the other position does not correspond to the normal spring characteristic, but rather to the modified spring characteristic, can reduce the required force that must be brought about by the magnet system. This also makes it possible to use a smaller and therefore less expensive magnet system.
  • the return spring is preferably performed according to the characterizing part of claim 9, whereby a kinking of the return spring is prevented (see also DE-OS 33 35 712).
  • the 1 has a lower housing part 10 and an upper housing part 11 connected to it.
  • the lower housing part 10 essentially accommodates the magnet armature system 12, which consists of an L-shaped magnetic yoke 13, a magnetic core 14, which is fastened to the lower housing part in a manner not shown and a hinged anchor 15 is formed.
  • the magnetic core 14 is surrounded by a coil 16, which is only indicated schematically in FIG. 1.
  • a guide element 22 is fastened, which has an extension 23 which projects beyond the cutting edge 21 into a groove 24 in the lower housing part 10 and thus ensures a lateral fixation of the hinged anchor 15.
  • the guide element 22 has an eyelet 25 which is penetrated by a connecting rod 26, so that the connecting rod 26 is articulated on the eyelet 25.
  • the actual magnetic force demand curve generated in this way is the curve M B , which is clearly below the curve M A , from which it can be seen that the magnet system can be designed to be weaker than that of commercially available arrangements.
