Definitions

  • the invention relates to a polarized, electromagnetic relay with an angled yoke arrangement, consisting of two yokes arranged in parallel at a distance from one another with a permanent magnet arranged between them and lying between armature plates, the legs of this yoke arrangement carrying an excitation coil and the permanent magnet arranged in a pivotable armature rocker with its Anchor plates can be brought into contact with the pole faces of the yokes.
  • a relay mentioned at the outset has become known, for example, from DE-C 966 845 or EP-A 1-oo74577. Both embodiments, however, have the disadvantage that the magnetic circuit is unsymmetrical due to the different shape of the L-shaped yokes and therefore relatively large electrical losses occur.
  • the invention has set itself the task of developing a polarized, electromagnetic relay of the type mentioned in such a way that the spring bracket serves as a central mounting element for the excitation coil, the yokes and the rocker, thereby eliminating the disadvantages of an asymmetrical magnetic frame caused by other known constructions be that on the one hand all mechanical tolerances and on the other hand all electrical tolerances refer to the central unit of two yoke core parts that are each homogeneous.
  • the yokes of the zero point or the K oordinatenursprungJ are the fact that the yokes are in turn each performed in two in itself homogeneous guide grooves, the mechanical tolerances over rocker spring bracket, Steg add, to the contact springs and the electrical tolerances over these two identical parts, air gap, coil former towards the winding).
  • the invention is characterized in that all parts are structurally and mechanically related to the spring bracket and locked there, which leads to easy manufacture.
  • the spring bracket itself is designed as an inexpensive plastic injection molded part and has the corresponding guide grooves, guide ribs and locking recesses.
  • the symmetry of the magnetic frame is achieved in that the two yokes are L-shaped and exactly symmetrical to one another, that their core legs extend over the entire length of the excitation coil and abut each other in the area of the excitation coil.
  • the yokes are designed as cost-effective stamped parts, the manufacture of which does not even have to be carried out with the greatest possible precision, because minor non-parallelities are eliminated by the fact that the yokes are precisely guided in homogeneous, corresponding grooves in the side walls of the spring bracket and this enables precise installation is.
  • the parallelism of the pole faces of the yokes is thus achieved solely by the guidance in the area of the grooves in the side walls of the spring bracket, with corresponding guide surfaces being arranged on the yokes. Error radii or errors in the bending surfaces of the entire yoke are always compensated for, even if there should be an air gap within the excitation coil between the core legs of the yokes.
  • the armature rocker 11 contains two armature plates 24, 25, which receive the permanent magnets 12 between them. It is important that the end faces of the anchor plate 24, 25 have a radius 26. The radius has the advantage that, despite the exact guidance of the pole faces 27, 28 of the yokes 14, 15, slight anti-parallelism of these faces can still exist due to existing inaccuracies.
  • the armature plates 24, 25 close the magnetic circuit from one pole face to the other.
  • the anchor plates 24, 25 should lie linearly on the pole faces. However, due to the manufacturing tolerances, this can only be achieved theoretically, and therefore a deliberate transition to a short-line or even punctiform support of the anchor plates 24, 25 on the pole faces 27, 28 is made.
  • the contact surfaces 29, 30 of the anchor plates 24, 25 on the pole surfaces 27, 28 are identified in the area of the arrows. The same contact surfaces also apply to the opposite yoke 15.
  • the pole faces 27, 28 of the yokes 14, 15 engage in the receiving openings 31, 32 of the rocker 11 formed between the two anchor plates 24, 25.
  • the latching of the bolt 13 of the rocker 11 in the latching recess 7 on the spring bracket 1 is achieved in that the latching recess 7 is slightly undercut and thereby receives a certain elasticity. Furthermore, the wall of the spring bracket 1 in the area of the guide 6 is weakened with a slot 8.
  • each yoke 14, 15 each has a pole face 27, 28 with lower and upper contact surfaces 29, 30, and the yoke also has a yoke plate 33 with lateral latching lugs 16a, 16b.
  • the locking lugs 16a, 16b engage in the locking openings 10a, 10b ( Figure 1, Figure 7) of the spring bracket 1.
  • the coil body of the excitation coil 17 is inserted into the receiving opening 36 of the spring bracket and locked there in the axial direction by short guide ribs 37, 38.
  • the guide ribs 37, 38 engage in corresponding latching openings 39, 40 in accordance with FIG. 9 on the coil flange 42.
  • These locking recesses 39, 40 are only on the connection-side coil flange 42, while no locking openings are provided on the opposite coil flange 43. However, they can also be formed on both coil flanges.
  • the core legs 22, 23 of the yokes 14, 15 described above then engage in the core opening 44 of the excitation coil 17.
  • P for guiding the yoke 14,15 in the region of the yoke bar 33 are each disposed laterally on the yoke plate guide projections 45,46, which engage in associated grooves 47,48 in the spring bracket. This ensures that the yoke plates 33 on the spring bracket 1 are secured in the area of the receiving opening 36.
  • grooves 47, 48 extend over the width of the spring bracket. This groove 47, 48 is produced in the plastic injection molding of the spring bracket 1 with a single tool, so that the grooves are exactly parallel due to this tool.
  • the spring bracket is universally interchangeable, so that the contacts can be freely selected in the spring bracket.
