Definitions

  • the invention relates to a magnet system for a relay with an angular yoke, the yoke leg arranged parallel to the coil axis is fastened on both sides in. Longitudinal grooves of a base body.
  • the yoke leg engages with a locking tooth in a recess in the base body.
  • it is further provided there to form deformable ribs in the grooves of the base body.
  • Such a press fit of the yoke in the base body leads to undesirable stresses in the plastic of the base body.
  • Another possibility of fixing the yoke in the base body would be to glue the yoke in the grooves.
  • the introduction of adhesive is relatively expensive in production; in particular, the yoke would have to be held in the correct position by additional precautions until the adhesive has hardened.
  • the object of the invention is therefore to provide a secure and easy-to-assemble yoke fixation in a magnet system of the type mentioned.
  • this object is achieved in that a holding plate made of elastic metal is arranged on the side of the yoke facing the coil, which is supported with its central part on the yoke leg and is braced on both sides in the longitudinal grooves of the base body with bent side parts.
  • the holding plate used according to the invention can be manufactured and assembled as a simple stamped and bent part. Due to its elasticity, it can absorb the forces that occur during the force-fitting fastening without putting excessive strain on the plastic base body.
  • the holding plate can be installed together with the yoke in one step by inserting it into the base body.
  • the holding plate is expediently preassembled on lateral latching teeth of the yoke leg before insertion by means of ear-shaped fastening tabs formed on both sides.
  • the holding plate has, in an advantageous embodiment, runners bent up on both side parts in the direction of insertion of the yoke leg.
  • the holding plate is provided, at least on one side part, with a corner which is bent open against the direction of insertion of the yoke and can be latched into a recess in the base body.
  • the holding plate is fastened by means of a fastening tab which is integrally formed in the central region and surrounds the yoke leg in a breakthrough in a U-shape.
  • the holding plate can additionally be formed on both sides and encompass the narrow sides of the yoke leg. exhibit kel.
  • This embodiment of the invention can be used with particular advantage when the holding plate is made of non-ferromagnetic material and the fastening tab which extends through the yoke leg simultaneously serves as a separating plate for an anchor leg resting on the yoke. Since the thickness of the separating plate is generally relatively small and in this case the entire holding plate has this small thickness, it may be expedient to provide stiffening ribs embossed in the holding plate transversely to the longitudinal direction of the yoke leg.
  • the holding plate can also have an extension with a cut-out opening, which lies above an opening in the yoke leg and is used for the positionally accurate attachment of an anchor holding spring.
  • the opening in the thick and relatively difficult to machine yoke can be worked with low accuracy, since the edges of the opening lie in the holding plate with dimensional accuracy.
  • the holding plate 14 which consists of resilient material, for example spring steel, lies with its central part 14a on the flat side of the yoke leg 7, while the side parts 16 bent away from the yoke leg serve for bracing in the grooves 11.
  • the holding plate 14 is fastened to the yoke leg 7 with the two fastening tabs 15, which snap into the projections 13 of the yoke leg 7. After this preassembly, the yoke leg is pushed together with the holding plate into the grooves 11 of the base body, the angled runners 16a on the side parts 16 making it easier to insert them.
  • a recess 20 can also be provided in the base body, into which the bent corner 17 engages.
  • the arrangement of the yoke leg 7 and the holding plate 14 in the base body 2 can be seen in the sectional view of FIG. 5, where part of the base body 2 is also shown.
  • the yoke leg 7 is pressed against the shoulders 18 in the grooves 11 by the holding plate 14, the side parts 1.6 of which are drawn untensioned here.
  • FIG. 4 additionally shows a slight modification of the holding plate 14, specifically the extension 19 drawn in dashed lines.
  • This extension then covers the opening 7a of the yoke leg 7, which is used to fasten and precisely position an anchor retaining spring 8a (FIG. 1).
  • the position of the holding plate 14 with its extension 19 can take over the function, namely with precisely cut inner contours 19a.
  • the contour 7b of the opening 7a in the yoke leg 7 can then be made somewhat larger than the recess in the holding plate 14, but relatively imprecisely. This simplifies the manufacture of the yoke.
  • This holding plate 21 has bent-up side parts 22 for bracing in the base body; angled runners 22a serve to facilitate the yoke assembly.
  • a centrally arranged fastening tab 23 is provided in this case, which is bent in a U-shape and is suspended in an opening 24 in the yoke leg 7.
  • An opening 25 in the mounting tab 23 serves as an assembly aid.
  • the holding plate 21 has side legs 26 bent at right angles, which abut the narrow sides of the yoke leg on both sides.
  • the free end 27 of the fastening tab 23 lies opposite the actual holding plate 21 on the flat side of the yoke leg 7 and at the same time serves as a separating plate for the armature leg 10 resting at this point.
  • the holding plate must, of course, be made of a non-ferromagnetic material, for example one Copper alloy.
  • the part 27 serving as a separating plate can lie in a recess 28 of the yoke leg 7 so that this separating plate projects as little as possible from the surface of the yoke leg 7.
  • the holding plate 21 has an overall small thickness and has ribs 29 stamped in for reinforcement.
