Definitions

  • the invention relates to an electromagnetic relay
  • T-shaped core with a longitudinal leg and two transverse legs, the longitudinal leg extending axially through the coil former
  • a U-shaped armature with two longitudinal arms running on both sides of the coil and a crosspiece, the armature having a first end section in the area of a first coil flange being mounted on an end section of the core and with its second end section in the area of the second coil flange having a working air gap forms the core, and
  • Such a relay is known for example from DE 34 43 094 AI.
  • the T-shaped core is extended to an E-shape or M-shape by extensions at the ends of the cross legs, which extend parallel to the middle leg.
  • the U-shaped armature is supported with the ends of its longitudinal arms on these extensions of the core, so that its transverse web forms the working air gap with the free end of the middle leg of the core.
  • This type of anchor bearing on an E-shaped core always requires additional bearing elements in the form of a bearing spring, which not only requires a corresponding effort in the manufacture with punching and bending, but also in the assembly with appropriate adjustment and riveting or welding processes . In another way, however, such an anchor can not be secured in its storage.
  • there is between the anchor cross leg and the core end only has a relatively small pole area in the working air gap, which cannot be easily increased either.
  • the aim of the present invention is to design a relay of the type mentioned at the outset in such a way that it can be assembled in a particularly simple manner with only a few, simply designed and easy-to-manufacture parts, while still having a reliable function and a high level of responsiveness due to a relatively large size Pole face in the working air gap are accessible.
  • this goal is achieved in that the armature is mounted on its crossbar on the free end portion of the longitudinal leg of the core and that the free ends of the armature longitudinal arms form two parallel working air gaps with the free ends of the core transverse legs.
  • the armature bearing and the working air gap are thus arranged reversed in comparison to the known relay, so that the U-shaped end of the armature surrounds the first coil flange and is thus already secured by its arrangement in the longitudinal direction of the coil axis. Since the armature can also be secured in other directions in the area of a coil flange by simple design, there is no need for a bearing spring with its corresponding manufacturing and assembly costs.
  • the two parallel working air gaps at the free ends of the armature enable a relatively large pole area.
  • This pole face can also be increased in that the core-transverse legs are provided at their ends with extensions in the direction of the armature longitudinal arms, so that the T-shape of the core is expanded into an M-shape or E-shape becomes.
  • the first coil flange has an attachment to secure the armature in its mounting.
  • this approach and the anchor have interlocking projections and / or Ausneh openings. A further securing of the armature in its storage can then be carried out by an attached housing cap.
  • the contact spring actuated by the armature is preferably arranged approximately parallel to the coil axis on the side of the coil opposite the armature, the armature movement being transmitted to the contact spring by a slide which is located between the transverse legs of the core on the one hand and the adjacent coil flange on the other hand perpendicular to the coil axis is guided flexibly.
  • An attachment of the housing cap mentioned can also provide additional guidance for the slide.
  • the first coil flange can have an extension in the form of a base, which defines a floor plane on which the coil axis is perpendicular, in addition to the armature bearing attachment.
  • the mentioned, at least one, contact spring and the at least one counter-contact element are then expediently anchored in the base perpendicularly to the floor plane, with associated connecting pins being guided vertically outward through the base floor.
  • at least one stop is preferably provided on the second coil flange, which defines the rest position of the counter-contact element and / or the contact spring.
  • the movable ends of the armature longitudinal arms are preferably biased away from the core into a rest position by a restoring spring force, and a pivot point is preferably provided in the central region of each of these longitudinal legs by a stop on a housing part, via which the restoring spring force the crossbar of the Presses anchor into its position on the core.
  • This ensures, even without a bearing spring, that the armature has the smallest possible air gap to the core in its rest position, which results in a good Flow transition and a high sensitivity. Since this return spring force is preferably applied by the contact spring, the number of individual parts of the relay can be kept particularly small.
  • the fulcrum in the central region of the armature can be produced by laterally formed shoulders of the armature longitudinal arms in connection with a corresponding rib or groove on the inside of the housing cap, so that no additional parts or assembly processes are required for this either.
  • FIG. 1 shows an exploded relay according to the invention
  • FIGS. 2 and 3 show a fully assembled relay according to FIG. 1 — without a cap — in two perspective views
  • FIG. 4 shows the fully assembled relay from FIG. 1 in a section through the coil axis.
  • the relay shown in the drawing consists of a coil former 1, a T-shaped or approximately M-shaped core 2, a U-shaped armature 3, a card-shaped slide 4, a fixed contact spring 5, a movable contact spring 6, a cap 7 and two coil connecting pins 8 anchored in the coil body.
  • the coil former 1 has an axial through opening 11 and a first flange 12 and a second flange 13, between which a winding 14 is applied.
  • An attachment 14 for armature mounting which merges into a base plate 15, is integrally formed on the end face of the coil flange 12.
  • Limiting pins 16 for the armature are also integrally formed on the extension 14, and plug slots 17 are also formed in this extension, through which connection elements 51 and 61 of the contact springs 5 and 6 can be guided vertically outwards through the base plate 15.
  • a stop lug 18 for the fixed contact spring 5 is also formed on the second coil flange 13 .
  • the T-shaped core 2 has a longitudinal leg 21 which is inserted into the through opening 11 of the coil body, and two transverse legs 22, at the ends of which side arms 23 are attached parallel to the longitudinal leg 21.
  • the U-shaped armature 3 consists of two longitudinal arms 31 and a transverse web 32, the latter being mounted on the free end section 24 of the core 2 and then lying in a recess between the first coil flange 12 and the base plate 15.
  • the two securing pins 16 of the base attachment 14 which engage in corresponding recesses 33 in the armature, secure it against lateral movements without its switching movement being impeded.
  • the free ends of the longitudinal arms 31 are widened into hook-shaped pole ends 34 which grip around the second coil flange 13 and form two parallel working air gaps with the transverse legs 22 and their side arms 23 of the core.
  • the fixed contact spring 5 and the movable contact spring 6 are anchored with their connecting elements 51 and 61, which are integrally formed or fastened in a known manner, in the plug-in slots 17 of the base attachment 14.
  • the two contact springs 5 and 6 are of identical design and are provided with contacts 52 and 62, respectively. The mutual overlap for making contact results from an L-shaped bend at their movable, contact-making ends.
  • the contact springs 5 and 6 are only cut from a flat sheet metal plate without bending and inserted into the coil body.
  • the mutual offset of their contacting ends only results from the geometry of the coil former or the slide 4.
  • This slide lies between the coil flange 13 and the transverse legs 22 of the core. It has a recess 41 through which the core longitudinal leg! 21 is put through.
  • the L-shaped bent end section 63 of the movable contact spring 6 bears against the stop lug 18 of the coil former 1 and thus receives its rest bias.
  • the L-shaped bent end section 53 of the fixed contact spring 5 rests on the slide 4.
  • the cap 7 is put over the relay. It forms a closed housing with the base plate 15. As can be seen from FIG. 4, the cap 7 has a ventilation hole 71 in the area of its upper side, which opens into an inwardly projecting extension 72. The latter approach forms an additional guide for the slide 4. As can also be seen from FIG. 4, the armature 3 is biased into its rest position by the restoring force of the working contact spring 6 via the slide 4. Lateral shoulders 35 of the armature abut ribs 72 of the cap, thereby forming a pivot point 73 for the armature.
