Definitions

  • the invention relates to an electromagnetic relay with a tongue armature arranged within a coil former approximately along its axis, which is supported on one side by its free end and which faces at least one opposing pole plate and is attached to the coil former by a ferromagnetic carrier part, the carrier part being a molded adjustment plate and also in the area between the adjustment plate and the fastening point on the coil former has a predetermined bending point in the form of torsion bars, such that the carrier part and thus the tongue anchor can be adjusted about this predetermined bending point by the action of an external magnetic field on the molded adjusting plate.
  • Such a relay is known from DE-A-2 723 219.
  • This structure has the advantage that the ferromagnetic adjusting plate and with it the tongue anchor attached to the carrier part can still be adjusted by the external magnetic field even when the relay is already closed in the housing and possibly also potted.
  • the basic principle of such a relay with an adjusting plate on the support part for the tongue anchor is also known from DE-A-2 701 230.
  • the adjusting plate is arranged parallel to the anchor within the coil tube, so that its diameter must be designed somewhat larger than would be necessary for the tongue anchor alone. In the case of very small relays, however, efforts are made to make the winding diameter and thus also the coil tube as small as possible to save space.
  • the object of the invention is to develop a relay of the type mentioned in such a way that on the one hand the advantages of magnetic adjustability from the outside are retained, but on the other hand a further reduction in the coil diameter is possible.
  • this object is achieved in that the adjusting plate is arranged approximately at right angles to the coil axis on the end face in front of the one bobbin flange - covering most of the end face of the bobbin - and in that the bobbin flange is also a fastening point for the carrier part.
  • the carrier part with the adjusting plate on the face of the coil body and outside of the coil tube, the space required within the coil body is reduced, so that the winding diameter can also be reduced.
  • the adjusting plate now requires a little more space on the end face in the area of the coil flange, this additional requirement is small compared to the savings in the winding.
  • the tongue anchor is attached to a separately manufactured support part.
  • This support part with the adjusting plate can be made of a material with a particularly low spring bending limit, while the tongue anchor can consist of thinner material with a relatively high spring bending limit with regard to its switching function.
  • the tongue anchor is expediently attached to a web bent out of the adjusting plate and angled in the direction of the coil axis.
  • the torsion bars are each connected to integrally formed fastening tabs which are attached to the end face of the coil flange.
  • These fastening tabs can be fastened, for example, by means of deformed fastening pins of the coil former.
  • the adjusting plate it is expedient for the adjusting plate to be arranged in a recess in the coil former which is adapted to its contour. In order to be able to record as many magnetic field lines as possible during the adjustment, the adjustment plate appropriately takes up a substantial portion of the end face of the coil body. This adjusting plate is advantageously widened in a T-shape at one end.
  • the carrier part can also be formed together with the tongue anchor as a one-piece, angled component.
  • the spring bending limit of the material is selected so that no permanent deformation occurs on the torsion bars with the slight switching movement of the tongue anchor, for example only 0.2 mm, while during the adjustment process the strong force applied to the adjustment plate Magnetic field is covered a relatively larger distance, which leads to permanent deformation on the torsion bars.
  • the adjusting plate is expediently reinforced in thickness by material folding in order to be able to accommodate as many magnetic field lines as possible.
  • the tongue anchor in its fastened end can merge into the adjusting plate formed by angling and on both sides of this end into one of the torsion bars, each of which has a fastening lug.
  • a flow transition flap formed parallel to the adjusting plate and formed by material folding can be formed on each fastening lug.
  • the relay shown in the drawing has a coil former 1 made of insulating material with a winding 2.
  • a spring-elastic tongue armature 3 arranged approximately along the coil axis is fixed at one end 3a in the area of the one coil flange 4 and with its free end 3b in the area of the coil flange 5 between the two counter-pole plates 6 and ' 7 arranged movably.
  • the opposing pole plates 6 and 7 are coupled with their sections 6a and 7a bent into a common plane to a flat, four-pole permanent magnet 8.
  • a support part 9 is used to hold the tongue anchor 3, which is essentially perpendicular to the coil axis on the end face in front of the coil flange 4 and has a notched web 9a which is bent in the direction of the coil axis and on which the fastening end 3a of the tongue anchor is fastened, for example by spot welding .
  • the carrier part 9 also forms an adjusting plate in the form of two adjusting tabs 9b and 9c, which are connected to two fixing tabs 9f and 9g via torsion bars 9d and 9e.
  • the fastening tabs 9f and 9g are attached to the fastening pin 10 of the bobbin flange 4 by means of bores 9h and 9i and fixed by hot deformation of this fastening pin 10.
  • the carrier part 9 consists of a ferromagnetic material with a low spring limit, preferably pure iron.
  • a magnetic field can be applied from the outside in such a way that a torque is exerted on the two adjustment tabs 9b and 9c and the torsion bars 9d and 9e are thereby permanently deformed. With this deformation, the web 9a, which is firmly connected to the adjustment tabs 9b and 9c, and the tongue anchor 3 fastened thereon are adjusted.
  • the magnetic field must be applied in such a way that the field lines strike the adjusting plate or the adjusting tabs 9b and 9c at an angle.
  • the field lines are preferably set to an angle that is greater than 60 ° and less than 90 ° with respect to the adjustment tabs.
  • the adjustment tabs 9b and 9c are arranged in a recess 11 of the bobbin flange 4, so that the adjustment tabs can be pivoted freely in the necessary area.
  • the adjustment tabs 9b and 9c are designed such that they occupy most of the end face of the coil body, with the exception of the area required by the attachment tabs 9f and 9g.
  • the adjustment tab 9b is therefore widened in a T-shape in the present example.
  • the coil body interior 15 can be covered by a film 12 together with the space 11 accommodating the adjustment tabs 9b and 9c, while the other end of the coil body is covered by a film 13 placed on the pole plate sections 6a and 7a.
  • foils 12 and 13 are used for provisional covering, in order to ensure, when the relay is subsequently potted in a ferromagnetic cap 14, that no potting compound penetrates into the interior 15 of the coil former 1.
  • these foils 12 and 13 serve for electrical insulation, since the tongue armature 3 and also the counter-pole plates 6 and 7 simultaneously serve for making electrical contact.
  • the opposing pole plates 6 and 7 are provided with integrally formed connecting pins 6b and 7b, while a connecting pin 9k for the tongue anchor is integrally formed on the carrier part 9.
  • pins 16 for the coil windings are also embedded in the coil body. All pins are arranged in the intended grid dimension or bent into this grid dimension.
  • the ferromagnetic cap 14 serves for the targeted guidance of the permanent magnetic flux as well as the excitation flux, the coupling between the carrier part 9 and the cap 14 being relatively good despite the existing air gap due to the large area of the adjustment tabs 9b and 9c and the mounting tabs 9f and 9g.
  • FIGS. 4 and 5 has a coil body 21 'made of insulating material with a winding 22.
  • a tongue armature 23 which is arranged approximately along the coil axis and is resilient in the switching area of the armature, is fastened with an end 23a in the area of the one coil flange 24 and with its free end 23b movably arranged in the region of the coil flange 25 between the two opposing pole plates 26 and 27.
  • the opposing pole plates 26 and 27 are coupled with their sections 26a and 27a bent into a common plane to a flat, four-pole permanent magnet 28.
  • a tongue part 23 is used to hold the tongue anchor 23 in the form of a support part 29, which is formed with the same material and is in the form of two lateral fastening lugs 29a and 29b and is connected to the tongue anchor 23 via torsion bars 29c and 29d.
  • an adjustment plate 30 is formed by right-angled bending, which is given a double wall thickness by folding the material twice. This adjusting plate 30 is initially guided vertically upwards with its leg 30a from the tongue anchor 23, then bent and arranged vertically downward with the leg 30b, from where the leg 30c in turn in the same plane as the leg 30a again runs above.
  • the adjusting plate 30 can absorb enough magnetic field lines when adjusting with a magnetic field in order to achieve an adjustment of the tongue anchor 23 by permanent deformation on the torsion bars 29c and 29d.
  • the spring bending limit of the tongue anchor or carrier material is chosen so that no permanent deformation occurs in the small switching movement in the range from 0.1 to 0.2 mm, while a plastic deformation occurs in the larger movements generated by the adjusting magnetic field via the adjusting plate is achievable.
  • the fastening lugs 29a and 29b are each non-positively fastened in the grooves of the coil former flange 24 by insertion.
  • the sheet metal of the support part 29 is bent upward at right angles with one leg 29e or 29f, then bent and then guided vertically downward to form flow transition lobes 29g or 29h.
  • These flow transition tabs 29g and 29h are offset somewhat from the adjusting plate 30 towards the outside of the relay, so that the free movement of the adjusting plate 30 is maintained when a sealing film 31 and a housing cap 32 are placed on it.
  • a connecting spike 29i is also integrally formed on the river transition tab 29h.
  • the relay is constructed and sealed as the relay of Fig. 1. The adjustment process is the same as that of the relay there.
