Definitions

  • the invention relates to an electromagnetic relay with a coil, the axis of which is parallel to the base plane of the relay and the core at one end forms a pole face for an armature mounted on a yoke edge, with an insulating carrier connected to the coil body, which in the region of the the armature facing coil flange carries two perpendicular to the base plane, provided with connection elements counter-contact elements, of which the first has a first contact section and the second two parallel planes, offset by multiple angular sections, the one forming the free end of this second counter-contact element Section as the second contact section is flush with the first contact section, and with a bridge contact spring attached to the armature, which in its first switching position bridges the first and the second contact section.
  • Such a relay is known from US-A-4 254 391, two counter-contact elements for the bridge contact being fastened one behind the other on the base body and perpendicular to the base plane at a relatively short distance from one another.
  • the second bridge contact element is longer than the first and bent over the free end of the first so that its contacting section lies above the first in its plane. Since the two mating contact elements are guided parallel to each other at a short distance, an additional insulating liner is required, which is integrally formed in the body in the citation.
  • this known relay needs an additional stop in the idle state of the armature, which is created by an appropriate design of the base body.
  • relays with a contact spring attached directly to the armature are known (DE-U-6 940 437). 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 stranded wire, 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.
  • the object of the invention is to provide a simple relay of the type mentioned, in which the mating contact elements of the bridge contact arrangement are arranged and designed such that the relay can have the same dimensions as a conventional changeover contact relay and that this relay can be used without additional measures or elements has a precisely defined stroke limitation for the armature or the contact spring attached to the armature.
  • this object is achieved in that the second mating contact element with its section facing the connecting element faces the first contact section in such a way that it includes the bridge contact spring and the bridge contact spring rests against this section in its second switching position and that the second mating contact element with its angled one Area that crosses the level of the bridge contact spring.
  • the contact spring is arranged between the two mating contact elements as in a changeover contact arrangement.
  • the contact spring serving as a contact bridge is in contact with both counter-contact elements in a switching state.
  • the second counter-contact element also serves to limit the stroke of the armature, so that no stroke adjustment is necessary.
  • the contacts are expediently adjusted in such a way that the closing and opening takes place.
  • 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 level or installation level of the relay.
  • One end of the invisible core is coupled to a yoke 4, which surrounds the coil on two sides and on the edge 5 of which a plate-shaped armature 6 is mounted.
  • a contact spring 7 is attached directly 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 in the present example is molded onto the coil flange 3. 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 a normally open contact is to be formed, or a stop for limiting the stroke of the armature is provided instead of the mating contact element 10.
  • 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 surrounds the contact spring 7 at its upper edge in a U-shape and forms a contact section 12.
  • This contact section 12 is arranged at a distance above the counter-contact section 9 so that it is flush with the latter.
  • Both the counter-contact element 9 and the contact tab 12 are each provided with a contact rivet which cooperate with corresponding contact rivets of the contact spring 7 as a bridge contact.
  • a Z-shaped mating contact element 13 is now provided, which has a bent extension 14 with a contact section 15, which in turn is aligned with the first mating contact element 9 .
  • the middle section 14 of the mating contact element 13 engages through a recess 16 of the contact spring 17, which in turn is fastened to the armature 6 and forms a bridge contact between the first mating contact element 9 and the contact section 15 with its two free ends 17a and 17b.
  • FIG. 5 shows a further embodiment for the second mating contact element.
  • This mating contact element 18 is bent with a U-shaped extension 19 around the free end of the contact spring 7 or 17 and forms a contact section 20.
  • This contact section 20 runs flush with the first mating contact element 9, parallel to the foot of the second mating contact element 18, but is opposite this so offset that the contact rivet can also be applied after the bending of the counter-contact element 18.
  • the mating contact element 18 also has a recess 18a.
  • a cooling plate 21 can be integrally formed on the extension 19 of the counter-contact element 18. This serves to radiate heat when switching high currents.
  • the first counter-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 engages around the contact spring (not shown) in a U-shape from below and has a molded-on contact section 28 which is flush with the contact section 24. This contact section 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, which as. 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 an incision 32 on both sides between its fastening part 31 a on the armature and its contact bridge part 31 b, so that the two parts of the spring are only connected via a torsion bar 33.
  • the contact spring can twist somewhat when switching in order to compensate for tolerances in the mating contact elements or the contact sections.
  • 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.
