Definitions

  • the invention relates to a residual current release according to the preamble of claim 1, a method according to the preamble of claim 4 and an apparatus for performing this method.
  • the object of the invention is to provide a residual current release in the form of a blocking magnet release of the type mentioned, in which the coil can be wound automatically.
  • a method for winding the coil and a device for carrying out the method are to be specified.
  • the outer flanges preferably form a circle, which can also be provided with teeth like a gear.
  • a cutout of any shape is left free on at least one flange according to the characterizing part of claim 4, into which a suitable segment of rivet made of electrically conductive material is used, to which one end of the winding wire is already attached or is still attached. It would also be conceivable for the segment, rivet, etc. to be inserted into the mold as a so-called insert during the manufacture of the coil former.
  • the drive wheels which can be designed according to the characterizing features of claims 7 and 8, are moved according to the invention against the two flanges in such a way that the end faces of the drive wheels with their collars enclose the flanges at their front edges.
  • the two opposite drive wheels are then pressed a little against the end edges of the flanges, so that in any case the driving force of the driven drive wheels is transmitted to the flanges of the coil body.
  • the opposite drive wheels can run loose or drive synchronously.
  • the drive wheels can expediently be designed as a drive roller, which covers the entire coil body.
  • the drive rollers can also be coated on the outside with material that increases the coefficient of friction. Rubber, for example, can be used as such material.
  • the drive force is then frictionally transmitted to the flanges of the coil body by means of the two drive rollers.
  • the blocking magnet release is formed in a known manner from two magnet yokes 10 and 12, which are bent at one end at 14 into a U-shape.
  • the yoke plates are connected to one another by means of rivet connections 16 and 18 with the interposition of an insulating plate 20.
  • a support extension 22 for an armature 24 shown in broken lines is indicated, whereas the pole faces 26 are formed on the other end of this edge.
  • a window 28 which is arranged at a distance from the edge located below and at a distance from the pole face 24 and thus defines a web 30.
  • a coil 32 is inserted into the window, which has a coil body 34, which has a drum region 36 and then two flanges 38 and 40.
  • the two flanges are also called the coil flanges.
  • the coil body has a medium through passage bore (not visible in FIG. 1) through which the web 32 engages on the magnetic yoke.
  • To assemble the coil former it can be constructed from two halves 42 and 44, which are placed over the web 32 and welded, glued or latched to one another at the contact surfaces 46 and 48, respectively.
  • the coil former can also be composed of two coil halves 42 and 44, which are connected to one another at one edge at their flange ends by means of a film hinge 48. These two halves 42 and 44 are folded over the web 32 and then connected to one another either by a welded connection or by latching means.
  • the design or the attachment of the coil over the web is known per se.
  • the flange edges of the coil flanges 38 and 40 are gear-like in the embodiments according to FIGS. 3 and 4.
  • the coil former which is composed of two halves in the usual way, is provided with a segment 50, into which a correspondingly designed segment 52 made of electrically conductive material is inserted.
  • the segment 52 is fastened to the coil flange, for example by clamping or firm locking. It is also possible to arrange it in the area of the parting line; in this case jamming or locking would be possible.
  • the coil former is now attached to the magnetic yoke in such a way that it can be rotated on the web.
  • This rotatability can be used to apply a winding to the coil former.
  • a device which consists of two at a distance adjacent drive shafts 60 and 62 is formed, of which the drive shaft 62 is driven, for example by means of a drive, not shown.
  • two drive wheels 64, 66, 68, 70 are fastened, wherein the drive wheels 64 and 66 can also be loosely attached to the shaft 60; it is only necessary to ensure that a displacement of the two wheels 64 and 66 in the axial direction of the drive shaft or the shaft 60 is prevented.
  • All four drive wheels are gear wheels with a ring gear 72, 74, 76 and 78. These teeth are exactly matched to the teeth on the flanges of the coil with regard to the pitch circle diameter and the number of teeth and the tooth shape.
  • each gear wheel is provided with projecting collars 80 and 82, the distance from which corresponds to the thickness of the coil flanges.
  • These collars 80 and 82 enclose the coil flanges, as can be seen in FIG. 3, and thus serve to guide the drive.
  • the distance between the two shafts 60 and 62 is reduced after interposing the magnetic yoke with the coil former attached thereto, so that either the wheels 64 and 66 press the coil flanges against the wheels 68 and 70 or vice versa.
  • the driven shaft 62 By rotating the driven shaft 62, the coil body can be set in rotation. With thicker winding wire, there is also the option of driving both shafts synchronously and thus increasing the forces to be transmitted.
  • the one wire end of the same, reference number 84 in FIG. 8, is fastened to the copper segment 52 and the drive shaft 62, or 60 and 62 is then driven. This will correspond to appropriate winding direction depending on the direction of rotation of the winding wire wound on the drum.
  • the winding wire is cut to length and a further piece of wire 86 is soldered onto the outer surface of segment 52, for example. This completes the winding process and the assembly process for winding the coil.
  • the winding wire must be insulated to avoid short circuits.
  • FIG. 4 shows a side view of the arrangement according to FIG. 3; drive wheels 64 and 68, coil former 30 and magnetic yoke 12 and 10 can be seen.
