Definitions

  • the invention relates to a coil former for a high-voltage transformer with axially juxtaposed winding chambers for high-voltage coil sections, which are mutually separated by flanges on a central hollow body and whose connecting ends are guided to connecting pins on a terminal block, the flanges with transfer slots from winding chamber to winding chamber are provided.
  • Such transformers are z. B. from DE-A-26 55 607 known. With several winding chambers for high-voltage coil sections, a gradation of the high voltage is achieved and breakdown of the insulation and thus a short circuit are avoided. Through the transfer slots, the winding wire can be drawn from chamber to chamber within the bobbin. However, the winding of such a transformer coil body is difficult to fully automate. A supply wire must be pulled between the most distant winding chamber to the terminal block. This wire must be well insulated to avoid breakdown between it and the coil wire in the winding chambers that it is passed. This reinforced Insulation could be created, for example, by pulling on an insulating tube. Such an insulating hose must be assembled by hand.
  • the object is achieved according to the invention by a spaced doubling of the hollow body forming an insertion slot, which opens out at the terminal strip and which is pulled through to the most distant high-voltage winding chamber, the insertion slot formed by it being laterally open along its entire length and also the flanges in extension of the open insertion slot are slotted.
  • the hollow body wall which forms a slot in which the winding wire is guided under the winding chambers, there is sufficient insulation with respect to this winding wire section and the individual windings in the winding chambers. Since the slot formed by the doubling is open to the outside along the bobbin, the winding wire can be pulled by a winding finger from the terminal strip to the most distant winding chamber when the bobbin is not yet wound. The winding process can thus be fully automated.
  • the winding of the coil body is carried out in such a way that the winding wire is guided from a wire guide, beginning at a connecting pin, in front of the insertion slot to the most distant winding chamber for high-voltage coil sections and, once there, from the wire guide as a whole Extending length is pivoted into the insertion slot, after which the most distant winding chamber for primary coil sections is fully wound and, progressively from this, chamber by chamber up to the terminal strip is fully wound.
  • the bobbin and winding process are matched to one another in such a way that the winding of the high-voltage coil body part in one operation is possible from the start of the winding wire to the end of the winding wire in several chambers.
  • the coil former 1 shown in FIG. 1 is a coil former for a high-voltage transformer, which is preferably operated in a clocked manner.
  • the high-voltage transformer has three winding chambers 3, 4, 5 on the high-voltage side, the winding chamber 5 being adjacent to a terminal strip 6 on which terminal pins 7, 8 are located.
  • the low-voltage side 9 of the coil body is only indicated as broken off, since the winding chamber of this low-voltage side has nothing special.
  • the bobbin 1 has a square hollow body 9, on which the flanges 10, 11, 12 and 13 are lined up at a distance in axial order.
  • the flanges 10 and 11 together with the hollow body 9 form the winding space 3
  • the flanges 11 and 12 together with the hollow body 9 form the winding space 4
  • the flanges 12 and 13 together with the hollow body 9 form the winding space 5.
  • a doubling 15 is placed on a square surface 14 of the hollow body 9, which forms an insertion slot 16 between it and the square surface 14, which is closed in the illustration on the left side of the coil body by means of a connecting web 17 while it is open at 18 on the right side of the bobbin.
  • the flanges 11, 12 and 13 are in the extension of the slots 16 on the right side of the coil body in the area of the slot opening 18 also provided with slots 19 so that a winding wire can be inserted into the open slot from the right side of the coil body.
  • the insertion slot 16 has an open mouth 20 on the terminal block 6.
  • the coil flanges 11, 12 and 13 are also provided with transfer slots 21 through which the winding wire can be passed, as will be described below.
  • the winding of the bobbin 1 can be automated because a winding finger 22 can wind the winding wire 23, which is attached to the connecting pin 7 with a first winding wire end 24, without interruption by any insulating measures on the bobbin 1 until the second winding wire end 25 finally ends up at the Pin 8 is struck.
  • Fig. 1 shows the winding wire 23 in three different positions. After striking the first connection end 24 on the connection pin 7, the winding finger 22 first pulls the winding wire 23 obliquely away from the coil former 1, a small piece of the wire 23 having already been drawn into the slot 16. The position of the wire is marked by the arrow a.
  • the winding finger 22 swivels the winding wire 23 into the insertion slot 16 via the position indicated by arrow b until the winding wire 23 is shown in dashed lines in FIG. 1 Assumes position in the insertion slot 16. The winding of the winding chamber 3 then begins.
  • FIG 3 shows the bobbin wound with the windings 26, 27 and 28, the windings 26, 27 and 28 forming high-voltage winding sections separated from one another in terms of high voltage.
  • the winding wire end 25 is then struck through the transfer slot 21 of the coil flange 13 through to the connecting pin 8. This winding does not require any special insulation of any winding wire sections.
  • the high-voltage part of the transformer wound in this way is sufficiently puncture-proof.
