Definitions

  • the present invention relates to a winding block for winding a winding wire on a magnetic core.
  • Such shims are generally of the type comprising an elongated body adapted to be placed in a corner on each corner of a core to allow direct winding of a wire on the latter.
  • These known wedges have the disadvantage of being heavy and expensive.
  • a first object of the present invention is to provide a shim, free from these drawbacks.
  • a second object of the present invention is to provide a shim allowing the separation of various winding layers or of various windings on the same core.
  • the various windings of a transformer or an inductor are generally wound on each other on a coil body.
  • armature which can be fitted onto a magnetic core of suitable dimensions and around which a first winding can be wound.
  • the cage has, at various points on its edges, slides projecting outwards, into which corner rods can be slid. These rods, arranged between each layer, thus allow a ventilation channel to be left between them.
  • This technique is not applicable for direct winding on a magnetic core, because in this case, we are just trying to do without a body or a winding cage.
  • the use of this technique involves the creation of a cage for each type of nucleus, which makes it relatively expensive consequence.
  • the invention proposes a wedge of the kind considered, characterized by the combination of at least two retaining elements projecting radially with recesses adapted to fit onto the retaining elements of an underlying wedge.
  • a shim 10 is formed of an elongated body. Having recesses 11 delimited by blanks 17, 17 'and closed at the ends by two end walls 12, 12'.
  • a median veil 14 is disposed between the walls 12, 12 ′ inside the body, so that said body is divided, lengthwise, into two symmetrical parts, the recesses 11 extending on either side and d other of said median veil.
  • the veil 14 is indented at 15 in its thickness, and the indentation 15 is in the form of a right isosceles triangle.
  • the recesses 11 are delimited by a plurality of transverse partitions 16, 16 'arranged inside the body between the web 14 and each of the blanks 17, 17', at regular intervals.
  • the lower edges 24, 24 'of the partitions 16, 16' cooperate with the notch 15 so that the edges 24, 24 'and the notch 15 form a right isosceles triangle whose the base is between the edges 25, 25 'of the blanks 17; 17 '.
  • the body is thus adapted to be placed in a corner on an edge, while being partially hollowed out.
  • each end of the body is provided with a retaining element 20, 20 ', projecting radially, in the form of cheeks, these cheeks being indented in their middle at 21, 21'.
  • the notches 21, 21 ' are rectangular.
  • the retains 20, 20 ' are offset from the ends of the body, so that the external faces 22, 22' of the retains 20, 20 'are substantially perpendicular to the internal faces 13, 13' of the walls 12, 12 '.
  • a shim is arranged in a corner on each edge of a magnetic core.
  • the winding wire is then spooled directly around the core fitted with shims.
  • the cheek-retained retainers 20,20 'prevent the winding wire from slipping, this avoiding having to attach the last turns of each layer, which saves winding time compared to techniques of prior art.
  • FIGS. 3 and 4 A second mode of use is illustrated in FIGS. 3 and 4.
  • Four wedges 31a, 31b, 31c, 31d are arranged in a corner on the edges 30a, 30b, 30c, 30d of a magnetic core 29.
  • wedges 33a, 33b, 33c, 33d respectively on the wedges 31a, 31b, 31c, 31d.
  • we will also do the same for the winding of a layer 36 thanks to the embedding of the shims 35a, 35b, 35c, 35d on the shims 33a, 33b, 33c, 33d.
  • the shims 31a to 31d, 33a to 33d, 35a to 35d are immobilized radially by the winding tension of the layers 32, 34, 36.
  • FIG. 4 it can also be seen that the retains 20 and 20 ′ of the shims 31 and 33 cooperate with the walls 12, 12 ′ of the shims 33 and 35, in. so that the wedges are immobilized with respect to each other in the longitudinal direction.
  • the various winding layers obtained are separated by ventilation channels 40, 41 and 42, thus making it possible to raise the current density in the winding wire compared to that possible in a conventional winding. where the various layers are glued to each other.
  • the shims cooperate with each other in such a way that they cannot slide over each other, thus fixing, once and for all, the winding layers in the desired position, without risk. to see, subsequently, these layers accidentally slide relative to each other, thus destroying the winding.
  • the wedge described in support of FIGS. 1 to 4, has been shown with a notch 15 in the form of a right isosceles triangle thus allowing the wedge wedge to be adapted to a core with rectangular section.
  • the shape of the notch 15 can be modified to allow the adaptation of the wedge on edges of cores whose planes form an angle other than 90 °.
  • the blanks 17, 17 'of the body cooperate with a median web 14 and partitions 16, 16', thus making it possible to produce a partially hollowed-out body.
  • the invention cannot be limited to the arrangement shown, a partially hollowed-out body which can be obtained by other means known to those skilled in the art.
  • the shape of the retainers 20, 20 ', indented at 21.21' has of course been determined as a function of the arrangement of the median web 14 and the blanks 17, 17 '. If this arrangement was modified, the shape of the retentions 20, 20 ′ would consequently be modified, so as to allow the cooperation described in support of FIGS. 3 and 4.
