Definitions

  • the invention relates to a coil former for electromagnetically actuated switching devices, consisting of at least one coil former made of plastic and at least one coil winding applied to the outside of the coil former, the coil former being a hollow body which is open at the two opposite ends and is rectangular in cross section and formed by rectangular side walls and at the front ends of the hollow body at a right angle to the side walls also projecting outwardly rectangular flange edges, which are dimensioned such that they laterally limit the coil winding.
  • Coil formers of the aforementioned type are used on a large scale in many fields of technology.
  • electromagnetically operated switching devices such as. B. Sagittarius.
  • the manufacture of the bobbin has so far been associated with a great deal of effort, which has a very costly effect in practice, precisely because of the high number of pieces required.
  • a very complicated injection mold is required, especially for producing the coil former of the coil former.
  • two movable mold jaws must be provided, which determine the outer surface of the hollow body of the coil carrier and the mutually facing inner surfaces of the flange edges.
  • two further molded parts must be present, which form the outer surfaces of the flange edges, and finally a pin must be provided which determines the cavity of the hollow body.
  • a device which is concerned with changing the induction of a coil by pressing a push button which results in a displacement of a magnetic core inside the coil, the coil sits on a sleeve, inside of which the magnetic core is movable.
  • These device parts are located in the interior of a plastic casing in the manner of a housing which is divided into two essentially semi-cylindrical halves which can be folded apart and folded apart via reinforcing ribs and around a flexible hinge strap.
  • the invention has for its object to provide a bobbin and to design such that a very simple manufacture is possible.
  • the object is achieved according to the invention in that the bobbin is divided into two symmetrical bobbin halves in a division plane that runs perpendicular to the flange edges and through two opposite side walls, which are connected to one another by two flexible hinge straps are seen in the unfolded position of the two coil carrier halves, are provided exclusively between two opposite corners of the flange edges in the area of the division plane, and that the rest of the shape of the coil carrier is made so that the coil carrier in the expanded position only between two Injection molded parts can be produced.
  • FIG. 1 to 3 illustrate an embodiment of a single bobbin of a bobbin for receiving a single winding.
  • the coil support consists of two coil support halves 1 and 2, that is, the coil support is divided according to the invention in a plane running perpendicular to the flange edges explained below.
  • the division plane is provided with the reference symbol 13 in FIG.
  • the coil carrier halves 1 and 2 are connected to one another by two flexible hinge straps 16 and 17.
  • the coil carrier has a hollow body with an essentially rectangular cross-sectional shape. This hollow body is formed by the two opposite rectangular sides 3 and 4 according to FIG. 2 and by rectangular side halves 5, 6, 7 and 8. According to FIG. 2, these rectangular sides merge into one another with rounded edges.
  • the dividing plane 13 runs according to the embodiment of Figures 1 to 3 such that two opposite sides of the rectangle with the rectangular side halves 5 to 8 halved and accordingly symmetrical coil carrier halves 1 and 2 are formed. Accordingly, the flange edges 9, 10, 11 and 12, which protrude vertically outwards at the ends of the previously explained hollow body, are symmetrically divided. Reinforcing ribs 14 and 15 are advantageously also provided on the outer surfaces of the flange edges.
  • the two coil carrier halves can be pivoted 180 ° to one another from an unfolded position according to FIG and folded up according to Figure 2.
  • the coil carrier has no undercuts in the unfolded position, so that the manufacture of the coil carrier in this unfolded position can be carried out in a simple manner by only two mold parts of an injection mold, namely with a mold part which corresponds to the shape of the top and another part of the mold that is adapted to the underside.
  • the bobbin with its two bobbin halves 1 and 2 and the flexible hinge straps 16 and 17 consists of a piece of tough plastic, the flexible hinge straps 16 and 17 being created in that the plastic is so thin in this area that on the one hand the flexibility or the flexibility is guaranteed, on the other hand there is a firm cohesion between the two coil carrier halves 1 and 2. As illustrated in FIG.
  • the two flexible hinge straps 16 and 17 are advantageously provided between two corners of the two flange edges 9, 10, 11 and 12 formed by the parting plane.
  • the two bobbin halves 1 and 2 as indicated by the dashed arrows 22 and 23, can be pivoted through 180 ° to one another and folded together according to FIG.
  • 2 pin-like projections 20 are advantageously formed in the area of the dividing plane 13 on one coil carrier half and corresponding holes 21 are provided on the other coil carrier half 1, so that the projections into the holes when the coil carrier is folded intervention.
  • a particularly firm cohesion of the two coil carrier halves is provided if four projections 20 and corresponding holes 21 are provided at the ends of the dividing surfaces 18 of the hollow body parts, that is to say close to the region in which the flange edge halves 9 to 12 with their dividing surfaces or cutting surfaces 19 come into contact the hollow body described are connected.
  • the coil carrier can be provided with a winding in a conventional manner.
  • FIGS. 4 to 12 A particularly important and preferred embodiment of the invention is shown in FIGS. 4 to 12. Thereafter, two split hollow bodies 24, 25 and 26, 27, each with two split flange edges, are joined together to form a unit by means of a flexible hinge strap 36 (FIG. 5).
  • the coil carrier halves 24 and 25 are accordingly connected again by flexible hinge bands 28 and 29 and the coil carrier halves 26, 27 by the flexible hinge bands 30 and 31. There are again pin-like projections 32 and 34 as arranged accordingly Nete holes 33 and 35 available.
  • the double bobbin is again produced, as described in relation to FIG. 1, in the unfolded position according to FIG.
  • the coil carrier halves 24, 25 and 26, 27 can be pivoted about the flexible hinge straps 28 to 31 by 180 ° to one another and, as illustrated in FIG. 8, folded together.
  • This collapse is not hindered by the special arrangement of the flexible hinge band 36 between the outer edge regions of two adjacent flange edges.
  • the flange edges run parallel to one another and the hollow bodies or the two coil carriers are located coaxially next to one another. If, as described above, reinforcing ribs are provided on the outer surfaces of the flange edges, these reinforcing ribs serve simultaneously as spacers in the area between the two coil carriers.
  • the flexible hinge band 36 is arranged and designed such that the two hollow bodies or coil carriers with their windings can be pivoted against one another by 180 °, so that a new position with respect to one another arises, as they do is shown in Figure 12. In this position, the central axes of the two hollow bodies or coil carriers and their windings run at a distance and parallel to one another.
  • a pin-like projection 37 and, on the other hand, an adapted hole 38 are advantageously provided on the edge regions of the flange edges, which lie opposite the flexible hinge strap 36, and which engage in one another in the folded state according to FIG.
  • each bracket 44 is provided with an outwardly projecting crank 45 which has an electrically conductive connection surface which projects so far outward that after the use of the coil former in the device in question, for example in a contactor, the current-conducting connection is not drawn power connections, for example resilient rails.
  • the two windings 40, 41 can be surrounded by a common adhesive tape. It goes without saying that then small recesses are provided in the adhesive tape, through which the crankings 45 can protrude outwards.
  • the main advantages that result in the exemplary embodiments according to FIGS. 4 to 13 are as follows. First of all, the manufacturing processes as described are considerably simplified, the mold halves of the injection mold being able to be designed in such a way that no harmful burrs and separating edges arise in the areas of the coil carriers in which the windings are applied. By dividing the coil carriers, inlet pockets for the beginning and the end of the respective winding can be provided very easily, if necessary. The two windings can be produced in one unit at the same time. The previous oil hoses to protect the respective solder joints on the wire ends of the windings can be omitted and it is no longer necessary to solder special flexible lines to the wire ends of the windings.
  • the wound bobbins are firmly connected to each other by the described flexible hinge straps as well as by the pin-like projections and the described holes, so that the thin wires for connecting the two windings to one another are not subjected to any stress. Since the two coil carriers are connected with their windings to form a unit, there is also easier storage, greater security during transport against damage and, finally, the insertion and establishment of the electrical connections in the device in question is simplified.
