Definitions

  • the invention relates to an electromagnetic relay according to the preamble of claim 1.
  • Such a relay is known from DE-OS 33 20 000.
  • the E-shaped ferromagnetic part is made of flat material as an E-shaped stamped part.
  • the thickness of the outer legs is therefore equal to the thickness of the central core leg.
  • the free ends of the outer legs can hardly be deflected laterally, but this type of design of the ferromagnetic part leads to wider external dimensions of the relay.
  • the outer legs are inserted at the free ends between rigid shoulders of holding parts for the contact springs.
  • the object of the present invention is to achieve a narrow design of the relay without increasing the height and without exposing itself to the risk that the free ends of the outer legs can be deflected elastically within certain limits.
  • the clear width between the two outer legs should always have a defined distance, so that there is no annoying air gap between the cross-displaceable pole plates and the associated legs.
  • This object is achieved by the features specified in the characterizing part of claim 1.
  • the clear width between the legs is determined by the width of the coil flange. This can be produced with sufficient accuracy in the spraying process. Since the armature, that is to say the pole plates with permanent magnet and the cross slide, can also be produced as a prefabricated unit with a low tolerance, there are also small fitting tolerances during the final assembly of the relay.
  • Fig. 1 the lower housing part 1 of the relay made of insulating material can be seen.
  • Partitions 3 and 4 protrude from the floor 2 of the lower housing part 1 at a distance from one another and parallel to one another.
  • the partitions 3 and 4 leave a receiving space 5 between them.
  • the electromagnet 6 shown in FIG. 2 is inserted into these.
  • the electromagnet 6 consists of the bobbin 7 made of insulating material with the coil winding 8 and the magnet system, which consists of a U-shaped yoke 9 and a central core leg 11 fastened to the base 10.
  • the magnet system therefore forms an E core, the outer legs 12, 13 of which are formed by the yoke 19.
  • the yoke 9 consists of an upright flat material made of ferromagnetic material. This allows the magnet system to be made very narrow. Nevertheless, the formation of a stray field is largely prevented by the upright outer legs, so that good electrical efficiency can be achieved.
  • the free leg ends 14 and 15 of the outer legs 12 and 13 protrude over the coil flange 16 of the coil body 8 hianus and rest on it.
  • the clear width between the two leg ends 14 and 15 is precisely defined, since the coil flange 16 can be produced with sufficient manufacturing accuracy in the manufacture of the coil former 7.
  • the outer legs 12, 13 are formed from upright flat material, there could be a risk that they will be bent apart and therefore no longer lie against the coil flange 16.
  • the outer legs 12 and 13 could be excited to vibrate by vibrations in the finished relay, so that the clear width between the free leg ends 14, 15 changes. This would then no longer guarantee that the cross-displaceable armature 17 shown in FIG. 3 would move properly.
  • the armature 17 consists - as can be seen in FIG. 3 - of a cross slide 20 made of insulating material, into which two pole plates 21 and 22 are inserted at a distance and parallel to one another.
  • a permanent magnet 24 is also inserted in the longitudinal direction on both pole plates 21 and 22.
  • the pole plates 21 and 22 are magnetized with opposite poles, so that a bipolar relay is formed in a manner known per se.
  • the partition walls 3 and 4 provided with the pressure elements 18 in the exemplary embodiment serve at the same time to separate the contact systems 25 and 26 arranged laterally parallel to the outer legs 2 and 3 from the electromagnet 6.
