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 pivotally mounted at one end on a flange of the coil body, in particular according to patent .... (file number P 31 32 239.5) .
  • the relay according to the main patent has the advantage that the armature movement is transmitted directly to the contact springs by the direct attachment of the contact springs in the insulating support of the armature, so that no actuating slide is required.
  • the connection of the movable contact springs to the insulating carrier provided there can thus avoid any friction between the armature and the movable contact springs, which is caused by the otherwise usual actuating slide.
  • any friction of the armature is not yet avoided in the exemplary embodiments of the main patent, since the cutting edge and pin bearings of the armature described there cause only slight, but not negligible, friction.
  • the object of the invention is to design a relay of the type mentioned, in particular according to the main patent, in such a way that the armature is mounted with virtually as few individual parts as possible without friction.
  • this object is achieved in that the armature is fastened with its mounted end in an armature holding member which is integrally formed on the coil body via one or more elastic webs.
  • the armature holding member By integrally forming the armature holding member 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 former and the iron parts of the magnetic circuit are normally stored on the coil former.
  • the anchor holding member is expediently frame-shaped, so that the anchor is held in the frame cutout by means of plug-in fastening.
  • the anchor is inserted into the recess of the anchor holding member in its longitudinal direction and held by a press fit or also by a snap connection.
  • a latching connection can be achieved, for example, by cooperating notches and projections on the armature on the one hand and on the armature holding member on the other.
  • the anchor holding member can also have a U-shaped recess in which the anchor is fastened by inserting it and, if necessary, also by snapping it into place. 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 holding member can have a closed rear wall in the extension of the longitudinal axis of the armature.
  • the elastic web which connects the armature holding member to the coil former, 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 oppositely rounded notches between the coil flange and the armature holding member.
  • the armature is arranged in an axial opening of the coil body, the armature holding member being molded onto the one coil flange via two bending webs arranged on both sides of the armature.
  • the armature can also be arranged on the side of the coil and fastened in an armature holding member which is correspondingly formed laterally on a coil flange.
  • the anchor holding member 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 in a relay, for example according to the main patent.
  • This coil former 1 which is shown without a 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 former 1 in its axial direction extends and with its free end 4b can perform switching movements between opposite poles, not shown.
  • a frame-shaped anchor is used to support the anchor Holding member 5, which is integrally formed on the bobbin flange 2 via elastic webs 6 and 7.
  • the anchor is held dabel by a press fit in the frame-shaped anchor holding member, while the bending webs 6 formed by oppositely rounded notches each form the axis of rotation of the anchor at its narrowest point.
  • the coil body with its flange 2 forms an extension 2a below the armature holding member 5, which carries, for example, coil connection pins 8.
  • the entire coil body with armature can be placed on a relay base body, not shown, as shown for example in the main patent.
  • 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 for in the main patent, be fastened in a correspondingly designed anchor holding member (see also FIG. 6).
  • Fig. 2 shows a partially slightly modified embodiment of a coil body with armature in a section, seen from above.
  • the coil former 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 holding member 18 is configured similarly to the anchor holding member 5 in FIG. 1. In relation to this, it has but a closed rear wall 18a, so that the inserted anchor end 4a is isolated.
  • the coil tube 11b is conical in this case, i.e. 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 body and gives it more stability.
  • this has the advantage that the core of the injection mold can be pulled out more easily due to the conical shape.
  • 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 holding member 25 integrally formed on the coil flange 23.
  • This anchor holding member 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 armature has one or more notches 27, into which latching lugs 28 of the armature holding member 25 engage.
  • FIG. 4 The embodiment according to FIG. 4 is largely similar to that of FIG. 3.
  • the coil former 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 one is formed Anchor 34 is coupled.
  • This armature 34 is fastened in an armature holding member 35 which is connected to the coil flange 33 via a bending web 36.
  • the armature 34 can be fastened in the armature holding member 35, for example according to FIG. 5.
  • the anchor holding member has a U-shaped opening 35a, into which the anchor 34 can be inserted from above. It is held in the anchor holding member 35 by the locking tooth 35b.
  • FIG. 6 shows a modified embodiment of the anchor holding member.
  • An armature holding member 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 in accordance with the main patent on lateral extensions. Otherwise, the design of the relay can also be varied in accordance with the preceding figures or according to the main patent.
