Definitions

  • the invention relates to a mechanical locking device for two switching devices, preferably electromagnetic switching devices, which prevents the switching on of a switching device by blocking the switch-on movement of the armature of this switching device, as long as the other is switched on and vice versa.
  • the contact bridge supports which can be moved parallel to the plunger anchors are connected to one another via levers attached to the housing, the free ends of which are loosely coupled to one another via a common locking slide. Due to the loose coupling, it cannot be ruled out under extreme conditions, for example if the attracted armature does not lie snugly on the yoke, that the other armature adversely affects the other switching device.
  • the present invention is therefore based on the object of preventing the switched-on switching device from being influenced by the other switching device with simple effort in any case.
  • the locking device in such a way that when the one switching device is switched on, the armature of the other switching device is removed from its rest position by entrainment from the associated yoke.
  • the system has proven particularly effective when the anchors are hinged anchors and the entrainment consists of a bracket that couples the two anchors in the direction of switch-off.
  • the bracket projects over the free ends of the hinged anchor and the bracket in turn bears against the respective contact slide in the switching-on direction thereof.
  • Use of the locking device according to the invention in reversing combinations is advantageous if the switching devices act as contactors in opposite directions direction of movement of their two hinged anchors are arranged in a housing as a contactor combination.
  • hinged anchors on their sides facing away from the bracket and the contact slides, are pressed against the yoke via springs that support a housing projection.
  • the contactor turning combination shown in the drawing consists of the lower housing part 1, in which the yokes 2 are held with the coils 3 of the hinged armature systems.
  • the hinged anchors 4 are supported on the one hand with the extensions 5 on the yokes 2.
  • springs 6 are used, which are supported on the one hand on the armatures 4 and on the other hand on a housing projection 7.
  • the free ends 8 of the hinged armature 4 protrude into a bracket 9 which, on the other hand, rests with its outer sides on extensions 10 of the contact slides 11, which are displaceably guided against the force of back pressure springs 12 in the housing halves 13.
  • the movable contacts held in the slides 11, which interact with fixed contacts, are not shown in the exemplary embodiment.
  • the bracket can also have the position shown in FIG. 2, namely between the two free ends 8 there is a projection 14 which forms the crowned free ones Ends 8 holds more or less positively in cooperation with the bracket arms.
