Definitions

  • the invention relates to an electromagnetic switching device with movable contact parts, which are held in a movable contact carrier and form opener and closer contacts with fixed contact parts, the contact carrier being elastically connected to the movable magnetic part.
  • the movable contact parts are designed as springs which are firmly connected at one end to the housing.
  • the other free ends of the springs are fitted with an attached driver for positive guidance of the springs.
  • An additional actuator can reach its end position even with a welded contact in the upper left corner and actuate the other normally open contacts, which is also desirable since the normally open contacts in the upper left part of the relay and the diametrically opposite normally open contacts in the lower right part are connected in series should be.
  • the present invention is therefore based on the object of strengthening a switching device of the type mentioned above such that the normally closed contact is excluded when the normally closed contact is welded.
  • the drawing shows a perspective view with the omission of the device housing, the basic structure of a switching device according to the invention.
  • the switching device shown in the drawing consists of the non-switching magnetic part 1 with the excitation coil 2, which is fixed in the usual manner in the housing, not shown.
  • the switching or movable magnetic part 3 is connected to the contact bridge support 4 via a bolt 5 and a bracket 6 and a spring 7 according to the invention.
  • the spring 7 is supported on the one hand on the bracket 6 and on the other hand, from a projection 8 of the contact bridge support 4.
  • the contact bridges 10 are held, as is known, via contact pressure springs 11 and interact with the fixed contact parts 12 and 13 as opener and closer contacts.
  • the symbolically represented return pressure springs 14 cause the movable magnetic part with the contact bridge support 4 to be pushed back and the contact bridge 10 with the fixed contact parts 12 to be closed, the contact compression spring 11 being compressed for the normally closed contact, as is shown by the contact arrangement in the upper right window of the contact bridge support 4. If the excitation coil 2 is now excited, the movable magnetic part 3 is moved towards the non-switching magnetic part 1 against the force of the back pressure springs 14. In the normal case, the upper contact bridge 10 comes to rest against the upper boundary of the window 9 and thus lifts the contact bridge 10 from the fixed contact part 12, so that the break contact is opened. After this opening, the lower contact bridge 10 comes into contact with the fixed contact parts 13, as a result of which the closing function is fulfilled.
  • the NC and NO functions must not occur at the same time.
  • the contact bridge 10 welds to the fixed contact parts 12, then the contact bridge 10 in turn comes to rest against the upper limit of the window 9.
  • further movement of the contact bridge carrier 4 is prevented since only the movable magnetic part 3 moves on.
  • the spring 7 is compressed so that the contact bridge 10 with the fixed contact parts 13 is not closed.
  • the spring 7 brings the contact bridge carrier into such a position that the contactor operates as intended.
  • the differential movement between the movable magnetic part 3 and the contact bridge support 4 can be used for a display, for example by actuating a microswitch, which is not shown in the drawing.
  • a welded opener is recognized by the fact that the existing indicator plunger is neither in the on or in the off position after the coil has been excited, but is in a central position.
