Definitions

  • the present invention relates to an electromagnetic relay according to the preamble of claim 1.
  • Such a relay is known from DE-U-7 529 555.
  • the legs holding the pressure spring are cut out of the yoke material and are therefore not deflectable in a resilient manner, but at most can be bent.
  • the pressure spring must be elastically deformed when it is inserted. Under certain circumstances, this can influence the spring characteristic to such an extent that it no longer lies within a tolerance to be demanded.
  • the known pressure spring is obviously bent at multiple angles, so that the crossbar is more flexible. But even such angled bends can have an unfavorable effect on the spring characteristics.
  • the present invention is intended to achieve the object of specifying a construction for a relay with a pressure spring of the type mentioned at the outset, with which it is possible to snap the pressure spring into the legs without or at most with little elastic deformation.
  • the pressure spring can easily be snapped in by lateral deflection of the legs without changing their spring characteristics.
  • the legs can be thin-walled due to the special arrangement of the openings in the legs and the associated plug-in tabs on the crossbar ends, which has a favorable influence on the elasticity and production.
  • the coil former can also be used for differently constructed hinged anchors, that is, for. B. for different types of relays.
  • Legs 4, 5, which extend in the direction of the coil axis 3, are formed on a flange 2 on the coil body 1, which is injection molded from elastic plastic. These are each provided at the end 6 with an opening 7, into which a plug-in tab 8 provided at the ends of a transverse web 9 made of resilient material can be latched. The engagement takes place by means of elastic deflection of the legs 4, 5 and / or of the cross bar 9.
  • the openings 7 and the plug-in tabs 8 are designed such that the cross bar 9 is fixed without play.
  • Legs 4, 5 and crossbar 9 thus form a U-bracket.
  • a leaf spring part 10 is integrally formed on the crosspiece 9, which resiliently presses against the angular edge of an angle hinged armature 12 of the magnetic circuit still consisting of core 13 and yoke 14.
  • the magnet coil 15 is wound onto the coil core.
  • a springy metal such as spring bronze, serves as the material for the crossbar 9 with leaf spring part 10.
  • the plastic with fibrous materials, such as. B. glass fibers, reinforced.
