Definitions

  • the invention relates to an electromagnetic relay with a coil, the axis of which is parallel to a base plane and the core of which has a pole face at one end.
  • a coil the axis of which is parallel to a base plane and the core of which has a pole face at one end.
  • for an armature mounted on a yoke edge also with an insulating support connected to the coil body, which carries in the area of the coil flange facing the armature two perpendicular to the base plane, provided with connection elements counter-contact elements, between which a contact spring attached to the armature with its free End is switchable.
  • Such simply constructed relays with a contact spring attached directly to the armature are known (DE-GM 69 40 437). They are used for switching relatively high currents at relatively low voltages, for example in motor vehicles or the like.
  • the contact spring on the armature which cooperates with one or two counter-contacts, usually has a power connection in the form of a strand, which leads via the yoke or directly to its own soldering or plug-in connection.
  • the contact spring also forms a make or break contact only with a counter contact element, while a stop is provided for the rest position of the contact spring and thus also of the armature instead of the second counter contact element mentioned above.
  • Auigzbe the invention is to design a simple relay of the type mentioned without changing the dimensions so that it can be used as a make or break contact for high inductive loads.
  • this object is achieved in that the second mating contact element has an extension which, around the contact spring, forms a contact tab which is flush with the first mating contact element but is arranged at a distance therefrom, and in that the contact spring in one of its switching positions as a bridge contact on the first mating contact element and on the contact tab is present.
  • the contact spring is still arranged between the two mating contact elements; however, these do not form a changeover contact, but rather a back contact by appropriately designing the second mating contact element.
  • the contact spring serving as a contact bridge is in one switching state only on the first mating contact element and in the other switching state on both mating contact elements. So since only the free end of the contact spring serves as a bridge contact and is thus live, the contact spring itself does not need a power connection, so that the current path is considerably shorter and the complex and problematic strand connection, which is problematic at high currents, is eliminated.
  • the first counter-contact element also serves to limit the stroke of the armature, so that no stroke adjustment is necessary.
  • the contacts are expediently adjusted so that the closing and opening are the same done early. Instead of the two individual contact rivets, a longitudinal contact piece can also be used, so that the spring no longer has to carry current. This has the advantage that cheap spring material can be used.
  • the relay according to FIGS. 1 and 2 has a coil 1 with the coil flanges 2 and 3, the axis of which is parallel to the base plane or installation plane of the relay.
  • One end of the invisible core is coupled to a yoke 4, which surrounds the coil on two sides and on whose edge 5 a plate-shaped armature 6 is mounted.
  • a contact spring 7 is directly attached to the armature via rivets or welded connections 8, and its free end 7a can be moved between a first mating contact element 9 and a second mating contact element 10.
  • Both mating contact elements are each provided with a connecting pin, a plug or solder pin 9a or 10a.
  • the mating contact elements 9 and 10 are anchored in an insulating carrier 11, which is molded onto the coil flange 3 in the present example. However, this carrier could also be connected to the coil in any form in the form of a base plate.
  • the mating contact element 10 can either be omitted entirely if only one closer is to be formed, or instead of the mating. contact element 10, a stop for limiting the stroke of the armature is provided. However, if a changeover contact is desired, the mating contact element 10 in such relays is arranged in mirror image to the mating contact element 9, so that the contact spring 7 switches back and forth between the two.
  • the mating contact element 10 has an extension 10b which engages around the contact spring 7 at its upper edge and forms a contact tab 12.
  • This contact tab 12 is arranged at a distance above the counter-contact element 9 so that it is flush with it.
  • Both the counter-contact element 9 and the contact tab 12 are each provided with a contact rivet 9b or 12b, which interact with corresponding contact rivets 7a and 7b of the contact spring 7 as a bridge contact.
  • Fig. 5 shows a further embodiment for the second Mating contact element.
  • This mating contact element 18 is bent in a U-shaped manner with an extension 19 around the free end of the contact spring 7 or 17 and forms a contact tab 20.
  • this contact tab 20 is aligned with the first mating contact element 9, it is arranged parallel to the second mating contact element 18, but opposite this so offset upwards that the contact rivet can also be applied after the bending of the counter-contact element 8.
  • the mating contact element 18 also has a recess 18a.
  • an additional cooling plate 21 can be integrally formed on the extension 19 of the mating contact element 18. This is used for heat radiation when switching high currents.
  • the first mating contact element 22 is anchored in a carrier 23.
  • a contact section 24 bent at a right angle supports the contact rivet 25.
  • the second mating contact element 26 is anchored in the carrier 23 at a right angle to the first mating contact element 22. It has an extension 27, which surrounds the contact spring (not shown) in a U-shape from below and has a molded-on contact tab 28 which is aligned with the contact section 24. This contact lobe 28 has a contact rivet 29. With the two contact rivets 25 and 29, the contact spring (not shown) forms a bridge contact.
  • An extension 30 is also formed on the second counter-contact element 26 and serves as an adjustable stop for the contact spring.
  • the contact spring can be L- shaped according to FIG. 1. 9 and 10 show further developments of this contact spring.
  • the contact spring 31 according to FIG. 9 has between its fastening part 31a on the armature and hers Contact bridge part 31b has a cut 32 on both sides, so that the two parts of the spring are only connected via a torsion bar 33. As a result, the contact spring can twist somewhat when switching in order to compensate for tolerances in the mating contact elements or the contact tab.
  • FIG. 10 Another embodiment of the contact spring is shown in FIG. 10.
  • the contact spring 34 shown there has a recess 35 which also serves to reduce the cross section and allows the spring to be twisted to compensate for tolerances.
  • the spring 34 is more dimensionally stable than the spring 31. Due to the trapezoidal inward edges 36 of the recess 35, the spring action can be set to a desired optimal value.
