Definitions

  • the invention relates to an electromagnetic relay with an elongated armature which extends essentially parallel to the axis of the excitation coil and is attached at one end directly to an armature support part (5) made of insulating material which is pivotally connected to a flange of the coil body.
  • the object of the invention is to design a relay of the type mentioned in such a way that the armature is stored with as few individual parts as possible practically without friction.
  • the armature support part By integrally forming the armature support part on the plastic coil body, it is possible to obtain a friction-free armature bearing and to save additional parts. In addition, tolerance accumulation is prevented since there are no separately manufactured intermediate links between the armature and the coil body and the iron parts of the magnetic circuit are normally stored on the coil body.
  • the anchor support part is expediently frame-shaped and holds the anchor in the frame cutout by means of plug-in fastening.
  • the armature is inserted in the longitudinal direction into the recess of the armature support divider and held by a press fit or also by a snap connection.
  • Such a locking connection can be achieved, for example, by cooperating notches and projections on the anchor on the one hand and on the anchor support part on the other.
  • the anchor support part can also have a U-shaped recess, in which the anchor is fastened in a snap-in manner by insertion. If it is necessary to insulate the armature end from metallic parts of the magnetic circuit, for example from a metallic relay cap, the armature support part can have a closed rear wall in the extension of the longitudinal axis of the armature.
  • the elastic web which connects the armature support part to the coil body, expediently has a rectangular cross section at its narrowest point, the narrow side of which extends in the direction of the axis of rotation of the armature.
  • This elastic web or the elastic webs are formed in a preferred embodiment by two counter-rounded notches between the coil flange and the armature support part.
  • the armature is arranged in an axial opening of the coil body.
  • the armature can also be arranged on the side of the coil and fastened in an armature carrier part which is correspondingly formed laterally on a coil flange.
  • the anchor carrier part can also carry one or more elongated contact elements which are fastened parallel to the anchor and are moved together with it.
  • the bobbin with armature shown in perspective in FIG. 1 can be used, for example, in a relay as described in the earlier application.
  • This coil body 1 which is shown without winding, has two coil flanges 2 and 3, an elongated rod-shaped armature 4 having its one end 4a being mounted in the region of the coil flange 2, so that it extends through an opening 1a of the coil body 1 in its axial direction extends and with its free end 4b can perform switching movements between opposite poles, not shown.
  • the armature is held by a press fit in the frame-shaped armature support part, while the bending webs 6 formed by oppositely rounded notches each form the axis of rotation of the armature at its narrowest point.
  • the coil body with its flange 2 forms an extension 2a below the armature support part 5, which, for example, coil connecting pins 8 wearing.
  • the entire coil body with armature can be placed on a relay base body, not shown, as is shown, for example, in the earlier application.
  • Contact spring sets which can be actuated by the armature can either be attached to the side of the coil body or fastened in the base body mentioned.
  • the movable contact springs can also, as provided in the earlier application, be fastened in an appropriately designed armature support part (see also FIG. 6).
  • Fig. 2 shows a slightly modified embodiment of a coil body with armature in a section, seen from above.
  • the coil body 11 with the flanges 12 and 13 carries a winding 11a, while the rod-shaped armature 4 is arranged in its interior.
  • To close the magnetic circuit serve two brackets 14 and 15, which are brought with their ends 14a and 15a to the mounted armature end 4a and with their ends 14b and 15b each form working air plates 16 and 17 opposite the armature end 4b.
  • the system can be polarized by means of a permanent magnet (not shown), so that the armature is pulled towards one or the other magnetic circuit bracket 14 or 15 depending on the excitation.
  • the anchor support part 18 is designed similarly to the anchor support part 5 in FIG. 1. Compared to this, however, it has a closed rear wall 18a, so that the inserted anchor end 4a is insulated.
  • the coil opening 11b is conical in this case, i. H. the opening is only narrow in the area of the coil flange 12 near the armature bearing, while it is wider in the area of the coil flange 13 near the free armature end. This enables an unimpeded switching movement of the armature, while on the other hand the space not required for the switching movement is filled by the plastic of the coil former and gives it more stability. In the manufacture of the bobbin, this has the advantage that the core of the injection mold can be pulled out more easily due to the conical shape. Furthermore, the coil body according to FIG. 2 has two stop lugs 19 in the area of the coil flange 13, by means of which the armature stroke can be exactly limited.
  • FIG. 3 shows another embodiment of the coil former in a detailed illustration.
  • the coil body 21 with winding 21a contains in its interior a yoke 22 which is angled on the coil flange 23.
  • the rod-shaped armature 24 is arranged parallel to the coil axis next to the coil and is fastened in an armature support part 25 integrally formed on the coil flange 23.
  • This anchor carrier part 25 is also connected to the coil body 21 via one or more bending webs 26 and permits a switching movement of the armature 24.
  • the embodiment according to FIG. 4 is largely similar to that of FIG. 3.
  • the coil body 31 has an elongated, straight yoke 32 in its interior, which projects over the coil flange 33 in the axial direction and to which an angled armature 34 is coupled.
  • This armature 34 is fastened in an armature support part 35, which is connected to the coil flange 33 via a bending web 36.
  • the anchor 34 can be fastened in the anchor carrier part 35, for example according to FIG. 5.
  • the armature support part has a U-shaped opening 35a, into which the armature 34 can be inserted from above. It is held in the anchor carrier part 35 by the latching tooth 35b.
  • FIG. 6 shows a modified embodiment of the anchor support part in a detailed representation.
  • An armature carrier part 43 is formed on the bobbin 41, which is only indicated, via bending webs 42, which not only carries an armature 44, but also movable contact springs 45 and 46 on lateral extensions. Otherwise, the design of the relay can also be varied in accordance with the preceding figures.
