Definitions

  • the invention relates to an electrical coil whose turns are arranged in several layers according to the preamble of claim 1.
  • the beginning and end of the winding wire often have to be positioned on one and the same end face of the coil in order to be able to easily connect it to an electrical circuit.
  • the connection ends are usually fixed on the front side of the supporting body of the coil.
  • an orderly layer structure is sought in the coil winding technique, in which the individual turns of the winding wire are wound directly next to each other. At the end of a layer, the laying direction is reversed and in each subsequent position, the wires then lie in the grooves formed between the turns.
  • Windungslagen are in this winding technology beginning and end of the winding wire on the same end face of the bobbin.
  • the wire terminates on the opposite side of the bobbin.
  • the wire must be positioned with additional measures and means, such as molding, baking or gluing process reliable on the desired front page. In the worst case, the last winding layer must be omitted.
  • the aim is to optimize the structure of the winding layers so that even with an odd number of Windungslagen the end of the winding wire can be positioned on the same coil end side as the beginning of the coil, without requiring additional space.
  • the last turns are inserted in the previously formed on two opposite longitudinal sides of the coil gaps with a larger pitch when winding the outer layer, occur at the two remaining longitudinal sides of the coil intersections of the winding wire.
  • the gaps on the opposite longitudinal sides of the outer layer from each other have a distance from several adjacent turns.
  • the winding wire is alternately offset laterally on one of the two remaining longitudinal sides to form the gaps by one or more wire thicknesses.
  • the gaps in the outer layer are arranged on the opposite broader longitudinal sides. The wire crossings lie on the narrower, opposite longitudinal sides.
  • FIG. 1 shows a three-dimensional representation of a coil with an odd number of layers before winding the last layer
  • FIG. 2 shows a three-dimensional view of the coil with the gaps on the longitudinal sides of the outer layer
  • FIG. 3 shows a development of the outer layer of the coil from FIG. 2
  • FIG. 4 shows a three-dimensional representation of the coil with a completely wound outer layer
  • FIG. 5 shows a development of the outer layer of the coil from FIG. Embodiments of the invention
  • an electrical coil in a three-dimensional view is designated 10. It consists of a winding 11 with a plurality of turns 12, which are arranged on the longitudinal sides of the coil 10 in a plurality of layers 13 on a support body 14 side by side. Due to its rectangular shape, the coil 10 has two opposite broad longitudinal sides 10a and 10c and two narrow longitudinal sides 10b and 10d. The coil 10 is wound with an odd number of layers, wherein the beginning and end of the winding wire 15 are to be positioned on the support body on the left end face 1 Oe of the coil.
  • Figure 1 shows the coil 10 in three-dimensional view before winding the last outer layer.
  • the beginning 15 a of the winding wire 15 is fixed in a slot 16 on the upper shoulder 14 a of the support body 14 on the left end side 10 e of the coil 10.
  • the windings 12 are wound side by side in a plurality of layers 13 on the support body 14, so that the penultimate layer is a layer with an even number of layers.
  • the last turn of this penultimate position is thus on the left end 10e of the coil 10. From there is now wound with the winding wire 15 in the direction of arrow 17, the outer last layer, which has an odd number of layers.
  • FIG 2 shows the coil 10 in three-dimensional view after winding the first part of the outer last layer 13a. It can be seen that in this outer layer 13a at the two opposite wide longitudinal sides 10a and 10c defined gaps 18 are formed between the windings 12 by the winding wire 15 alternately wound laterally offset on one of the two narrow longitudinal sides 10b and 10e by one wire thickness becomes. The gaps 18 therefore also have the width of the wire thickness of the winding wire 15. Die
  • Gaps 18 have on the longitudinal sides 10a and 10c of the outer layer 13a from each other a distance of several adjacent turns 12th
  • Figure 3 shows the development of the outer layer 13a of the coil 10 with a separation along the line III-III of Figure 2.
  • the settlement is broken down into the four longitudinal sides 10a to 10d. It can be seen there that initially the turn 1 is displaced laterally in the region of the lower narrow longitudinal side 10d in order to form a first gap 18a on the front wide longitudinal side 10a.
  • the second turn is now placed next to the first and the third turn is laterally offset in the region of the upper narrow longitudinal side 1 Ob by a wire thickness.
  • a further gap 18b now arises in the region of the rear wide longitudinal side 10c.
  • the remaining turns of the outer layer 13a are now arranged by the winding wire 15 is alternately bent laterally to one of the two narrow longitudinal sides 10b and 10d by a wire thickness.
  • the winding wire 15 must now be led back in several turns 12 to the left end 10e of the coil 10, as shown in Figures 4 and 5.
  • the last turns 12a are wound with a greater pitch to the left end face 10e of the coil 10 by the winding wire 15 being inserted into the previously released gaps 18.
  • the end 15b of the winding wire 15 is finally fixed in a further slot 16 in the shoulder 14a of the support body 14, so that now the beginning and end of the winding wire 15 are positioned side by side.
  • the winding process can be described with reference to the development of Figure 5.
  • the winding wire 15 is therefore starting from Figure 3 on the lower narrow longitudinal side 10c, the two last-wound turns of the outer layer 13a cross and then inserted into the recognizable from Figure 3 gap 18d on the front longitudinal side 10a. Subsequently, in the region of the upper longitudinal side 10b, it crosses two further turns of the upper layer 13a and then enters the gap 18c from FIG. 3 on the rear longitudinal side 1c.
  • the winding wire 15 thus alternately crosses two turns of the outer layer 13a alternately on the upper and lower longitudinal sides 1 Ob and 1 Od until it reaches the first gap 18a in FIG. 3 at the left end face 10e and finally there at the slot 16 of the supporting body 14 is fixed at right angles with its end 15b.
  • the outer layer 13a is not wound over the entire width of the coil, so that some turns are missing for the right end face 1 Od. In this area, therefore, the penultimate layer 13 according to FIG. 1 is no longer covered by the outer layer 13a. This is indicated by dashed lines in the developments according to FIGS. 3 and 5.
  • the crossings 19 in the region of the upper and lower narrow longitudinal sides 10b and 10d of the coil 10 are formed such that the upper winding wire 15 crosses two windings 12 underneath.
  • Winding is arranged (see gap 18b in Figure 3).
  • the winding wire end 15b can be fixed securely out of this gap 18b in the slot 16 of the support body 14.

Abstract

L'invention concerne une bobine électrique (10) comprenant une pluralité de spires (12) disposées les unes à côté des autres en plusieurs couches (13), le début (15a) et la fin (15b) de la bobine se situant d'un seul et même côté frontal (10e) de la bobine. L'invention vise à optimiser la structure en couches de telles bobines avec un nombre de couches impair. A cet effet, des vides (18) définis sur deux côtés longitudinaux de la bobine (10a, 10c) opposés sont laissés ouverts dans la couche extérieure (13a) enroulée la dernière, en ce que le fil de bobinage (15) est décalé latéralement d'une épaisseur de fil sur au moins un des autres côtés longitudinaux de la bobine. Les dernières spires (12a) de la couche extérieure (13a) sont ensuite insérées et positionnées avec un pas plus important dans les vides (18) précédemment laissés ouverts jusqu'au côté frontal (10e) de la bobine (10).
