Definitions

  • Such relays are known in many forms, for example from DE 35 28 715 A1 describing the closest prior art or EP 0 113 440 A1. These relays have the advantage of a very simple construction, the use of an additional slide being avoided by the direct connection between the armature and the contact spring, and the contact spring often also taking over the storage and resetting of the armature. With the two contact pieces on the free end of the contact spring, this can be used as a bridge contact or as a double contact, a soft spring characteristic being achieved by the constriction between the fastening of the spring on the armature and the transverse legs. At the same time, torsion of the spring to compensate for tolerances when switching is possible in this way.
  • the object of the invention is to provide a relay of the type mentioned while maintaining the advantages of the T-spring shape mentioned, but at the same time the effects of welding and hooking in the contact area are significantly reduced with the same dimensions.
  • the inventive design of the support tab ensures that the flexibility and torsion of the contact spring is fully retained when the contacts are closed, while when the contacts are opened the impact of the anchor acts on the support tab in the immediate vicinity of the contact pieces, so that any welded or hooked contacts be opened because the damping effect of the soft contact spring does not come into effect in this case.
  • the prerequisite is of course that the point of contact between the end edge and the support tab is so close to the contact pieces that the Length of the support tab or the section of the contact spring lying in this area does not experience any significant deflection.
  • the support tabs In order to obtain a defined impact point, it is furthermore expedient for the support tabs to be bent in the direction of the anchor surface. For the same purpose, however, it is also possible for the anchor to have embossments opposite the support tabs.
  • the relay shown in the drawing has a coil body 1 with a winding 2 and an angular yoke 3 on which a flat armature 4 is mounted.
  • a contact spring 5 is riveted or welded to the anchor at a fastening point 6 and fastened to the yoke with an arcuate rear bearing section 7.
  • the contact spring 5 In the area of the end edge 4a of the armature, the contact spring 5 is reduced in width and thus forms a constricted area 5a of smaller cross-section, while in its end section 5b it is widened in a T-shape outside the end edge 4a of the armature and forms two transverse legs 5c.
  • the contact spring 5 acts either as a bridge contact or as a double contact, depending on whether the two mating contact elements 10 are connected in parallel or in series in the load circuit. In the case of double contact, the contact spring 5 must of course have its own connection.
  • the contact spring can both bend slightly when the contacts are closed and can also be twisted about its longitudinal axis, thus achieving a tolerance compensation with respect to the mating contact elements and a uniform contact pressure.
  • the two cross legs 5c of the contact spring each have on their upper edge 5d - that is the edge facing the armature - a molded support tab 11 which engages with the armature edge 4a during the opening movement.
  • the upper edge 5d is immediately adjacent to the anchor edge 4a, i. that is, the distance may only be so large that the length of the support tabs does not substantially dampen the anchor joint.
  • the support tabs 11 can have an end section 12 bent toward the anchor. In this way, a defined stop on the anchor is defined. Instead of or in addition to this bending of the ends 12, a protruding embossing 13 could also be provided on the anchor in order to ensure this defined stop. A corresponding embodiment is shown in FIG. 4.
  • the support tabs can of course also contain further deformations, for example beads, in order to stiffen these support tabs.
  • a normally open contact is shown. This means that the contact opening takes place during the falling movement of the armature, that is to say it engages the support tabs on the side of the armature facing away from the pole face.
  • normally closed contacts where the contacts are opened when the armature is tightened. In this case, the support tabs would have to engage on the armature side facing the pole face.
