Definitions

  • the present invention relates to an electromagnetic relay according to the preamble of claim 1.
  • Such a relay is known from DE-OS 30 08 783.
  • the bobbin with the U-bracket with leaf spring part consists of a single molded part made of plastic. Although this type has proven itself well in practice, it is necessary for high accuracy in production to adhere precisely to the spraying conditions, in particular the temperature, and the mixing ratios of plastics containing fibers.
  • the object is to be achieved, despite lower precision requirements in the manufacture of the bobbin, to achieve a rational and high-quality manufacture of the leaf spring part with the same or better function thereof.
  • the crossbar with leaf spring part is a cheap stamped part made of suitable, resilient material, such as spring bronze, and can easily pass through W.Minks 30 elastic deflection of the legs and / or the crossbar can be snapped into the slots of the leg.
  • the coil body can also be used for other types of clap anchors, e.g. for different relay types.
  • Legs 4, 5 extending on a flange 2 in the direction of the coil axis 3 are molded onto the coil body 1, which is injection molded from a plastic molded part made of elastic plastic. At the end 6, these are each provided with at least one slot 7, into which a plug-in tab 8 provided at the ends of a transverse web 9 made of elastically resilient material can be latched. The locking takes place by elastic deflection of the legs 4, 5 and / or the crossbar 9.
  • the slots 7 and the plug-in tabs 8 are designed so that a play-free fixation of the crossbar 9 is obtained. SchenkeL 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 magnetic coil 15 is wound on 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 fiber materials, such as Glass fibers, reinforced.
