Definitions

  • the invention relates to a coil former for electrical devices, in particular electromagnetically operated switching devices, consisting of at least one core and at least one winding applied to the core, the core having an open hollow body on the two opposite ends for receiving the winding and on the Front ends has flange edges projecting vertically outwards.
  • Coil formers of the aforementioned type are used on a large scale in many fields of technology. Electromagnetic switching devices such as contactors can be considered as a special technical field.
  • the manufacture of the coil former 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, in particular, to produce the core of the coil former.
  • two movable mold jaws must be provided that cover the outer surface of the hollow body of the core 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.
  • 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 core is divided in a plane running perpendicular to the flange edges and in that the core parts are connected to one another by at least one flexible hinge band.
  • the core is divided in a plane running perpendicular to the flange edges and in that the core parts are connected to one another by at least one flexible hinge band.
  • Figures 1 to 3 illustrate an embodiment of a single core of a bobbin for receiving a single winding.
  • the core consists of two core halves 1 and 2. That is, according to the invention, the core is divided in a plane running perpendicular to the flange edges explained below. The Division level is provided in FIG. 3 with the reference symbol 13.
  • the core parts 1 and 2 are connected to each other in this embodiment by two flexible hinge straps 16 and 17.
  • the core has a hollow body with an essentially rectangular cross-sectional shape. This hollow body is formed by the two rectangular sides 3 and 4 lying opposite one another 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 division plane 13 runs such that two opposing sides of the rectangle with the side halves 5 to 8 halved and accordingly symmetrical core halves 1 and 2 are formed.
  • the flange edges 9, 10, 11 and 12, which project 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. Due to the action of the two flexible hinge straps 16 and 17, which are provided between two mutually opposite parts of the flange edges 9, 10, 11 and 12 in the area of the dividing plane 13, the two core halves can be swiveled 180 ° to one another from an expanded position according to FIG and folded up according to Figure 2.
  • the core has in the expanded position g eklappten no undercuts, so that the production of the core can be made in this unfolded position in a simple manner by only two mold parts of an injection mold, namely, with a molding which the shape corresponds to the top g MOVE and a further molded part, which is adapted to the bottom.
  • the core with its two core 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 formed in that the plastic is so thin in this area that on the one hand the flexibility or flexibility is guaranteed. on the other hand, there is a solid cohesion between the two core 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 core halves 1 and 2 as indicated by the dashed arrows 22 and 23 can be pivoted by 180 ° from each other and folded according to Figure 2 .
  • pin-like projections 20 are advantageously formed on one core part 2 in the region of the dividing plane 13 and corresponding holes 21 are provided on the other core part 1, so that the projections in the closed position of the core in the holes.
  • a particularly firm cohesion of the two core 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, i.e. close to the area in which the flange edge halves 9 to 12 with their dividing surfaces or cutting surfaces 1n the hollow body described are connected.
  • the core When folded, the core 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 divided hollow bodies 24, 25 and 26, 27, each with two divided flange edges, are combined to form a unit by means of a flexible hinge band 36 (FIG. 5).
  • the two hollow bodies or core halves 24, 25 on the one hand and 26, 27 on the other hand correspond in all details to the core halves 1, 2 according to FIGS. 1 to 3, so that the preceding explanations also apply analogously to the exemplary embodiment according to FIGS. 4 to 12.
  • the core halves 24 and 25 are accordingly again connected by flexible hinge straps 28 and 29 and the core halves 26 and 27 by the flexible hinge straps 30 and 31. There are again pin-like projections 32 and 34 and correspondingly arranged holes 33 and 35.
  • the double core is again produced as described in FIG. 1 in the unfolded position according to Figure 4. Since the double core is held together by the flexible hinge band 36, as mentioned, it can be removed as a unit from the injection mold.
  • the core halves 24, 25 and 26, 27 can then 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 cores are located coaxially next to one another. If, as described above, reinforcement ribs are provided on the outer surfaces of the flange edges, so this comparison serve stärkun g srippen in the range between the two cores at the same time as spacers.
  • the flexible hinge band 36 is arranged and designed such that the two hollow bodies or cores with their windings can be pivoted against one another by 180, so that a new position with respect to one another, as shown in FIG Figure 12 is shown. In this position, the central axes of the two hollow bodies or cores 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 is an electrically conductive type has end surface, which projects outwards so far that after the use of the coil body in the device in question, for example in a contactor, the current-conducting connection with power connections, not shown, for example resilient rails, is made.
  • the two windings 40, 41 can be surrounded by a common adhesive tape. It goes without saying that small recesses are then 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, and the mold halves of the injection mold can be designed so that no harmful burrs and separating edges in the area of the cores in which the windings are applied. By dividing the cores, inlet pockets can be provided very easily for the beginning and the end of the respective winding. 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 cores 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 production of the electrical connections in the device in question is simplified.
