Definitions

  • the invention relates to an electromagnetic switching device with fixed in a housing upper part and connected to a movable, guided in the housing upper, switching magnetic part movable contact part, as well as a bottom plate closing the housing upper part, screwed to it and holding the non-switching magnetic part.
  • the invention has for its object to provide a base plate suspension with which bruises of the magnet system are avoided at least within certain limits with a simple and inexpensive construction. This will be there in a simple way achieved by that the screws are assigned resilient attenuators that allow movement of the base plate relative to the housing part. Additional damping elements between the magnetic part and the housing can be omitted here.
  • the damping members consist of compression springs which are supported, on the one hand, directly or indirectly on the screw heads and, on the other hand, on the upper part of the housing and the screw threads are screwed into the base plate, whereby then advantageously the base plate lies in a recess of the upper housing part, so that the fastening of the device to the fastening surface is not impaired.
  • the compression spring is guided on a bushing which overlaps the thread of the screw and is provided with a support collar for the compression spring which is located directly or indirectly against the screw head and whose end facing away from the support collar is pressed against the base plate by the screw, and the compression spring is removed from the legs of a U -shaped holder held under pretension, one leg of which rests on the upper housing part, so the shock absorber can be preassembled as a complete unit and screwed in like a conventional fastening screw.
  • the holder is made of plastic and if the holder is inserted into an adapted opening in the upper housing part, so that the visual impression of the closed surface of the upper housing part is not disturbed.
  • Tolerance compensation rings as in the prior art, can also be inserted as an intermediate layer in a simple manner in the switching device design according to the invention.
  • the adjusting disks in which they are fastened to a holding web of the base plate with claws, they can be introduced as a unit with the screw itself.
  • the switching device shown schematically in the drawing consists of the upper housing part 1 and the base plate 3 connected to it via screws 2.
  • the non-switching magnetic part 4 is firmly connected to the excitation coil 5 on the base plate 3.
  • the fixed contacts 8a are fastened in the upper housing part 1 and the contact bridge carrier 7, which is connected to the switching magnetic part 6, is displaceably guided for the contact bridges in the usual manner against the force of a back pressure spring.
  • the screws 2 are assigned elastically flexible damping members, in the present case compression springs 9, which are guided on a bushing 11 provided with a support collar 10.
  • the bushing 11 is passed through a bore 12 in the upper housing part 1 and rests on tolerance compensating disks 13 inserted between the upper housing part 1 and the base plate 3.
  • the support collar 10 is supported by a disk 14 on the leg 15 of a U-shaped holder 16.
  • the spring 9 is supported, the other end of which rests on the support collar 10.
  • the screw head 18 with a spring ring 19 is passed through an opening 20 in the leg 15. To insert the screw into the holder 16, the inclined screw with the head 18 and the spring ring 19 is first pushed through the opening 20.
  • the spring is slightly tensioned, and by pivoting about the support of the disc 14 on the leg 15, the socket is pivoted into the position shown in the drawing, so that the spring is supported under tension in the holder 16 and as a complete component in an opening 21 in Upper housing part 1 can be inserted.
  • the bushing 11 comes through the bore 12, and the thread of the screw 2 is screwed into the threaded holes in the base plate 3.
  • the switching magnetic part 6 strikes the non-switching magnetic part 4; the blows are transmitted to the base plate 3.
  • the base plate and the housing cannot break because the compression spring 9 can compress so that the bottom plate 3 can stand out from the upper housing part.
  • a corresponding recess is provided on the bottom of the upper housing part, so that the base plate can move freely even when the switching device is screwed on.
  • additional damping elements for the non-switching magnetic part can thus be omitted.
  • the damping by the compression spring 9 can be adjusted in a simple manner, and the insertion of the component preassembled in the holder 16 does not require any special expertise and care, since any screw can be used here.
