Definitions
- the invention relates to a winding arrangement having a number of spaced apart in the axial direction and electrically connected to form a series connection winding sections, each having a conductor which is wound from an inner end to an outer end of the respective winding section and thereby ⁇ ßert the winding portion in the radial direction magnification, at least one winding portion is electrically connected at its äuße ⁇ ren end to the inner end of the succeeding coil portion in the axial direction.
- the invention further relates to a transformer and a coil or inductor with such a winding arrangement.
- the above-mentioned winding arrangement is known, for example, from EP 2 251 877 B1.
- the Wicklungsan ⁇ order shown there consists of a series connection of so-called disc windings, which are arranged at a distance from each other.
- the outer end of each disc winding is connected to the inner end of each adjacent axially disposed disc winding.
- a disadvantage is that the intermediate portion of the conductor which extends between the disc windings, not only the axial distance of the adjacent
- Disk windings but also the radial extent of the winding must bridge.
- the adjacent Scheibenwicklun- gene must therefore be arranged with a large distance from each other to make room for the said intermediate section.
- so-called over windings from the Pra ⁇ tice are known.
- camber windings the outer end of a disk winding is connected to the outer end of the axially succeeding disk winding, but this is wound from outside to inside. The change of the winding direction in the production, however, is complicated and leads to additional costs.
- the object of the invention is to provide a winding arrangement of the type mentioned, which is inexpensive to produce and their winding sections are arranged me a relatively small distance from each other.
- the interconnects insulated from one another abut one another and, with increasing number of turns, increase the winding section in a direction which is referred to here as a radial direction.
- a radial direction By winding are circumferential closed winding sections are formed, which limit an Ab ⁇ average area.
- the section inner spaces of the winding sections are at least partially aligned in the axial direction, so that the stack of winding sections defines an inner contour, which is referred to below as the winding interior.
- each winding section forms, with the exception of the first winding section of the series connection, an eccentric step area in which its inner winding layer has a greater distance from an imaginary central axis of the winding interior than outside level range.
- This compared with the other portions of increased distance corresponds to the distance between the inner and externa ⁇ ßeren end of the adjacent winding section, thus corresponds in other words to the thickness of the winding. Therefore, the outer conductor need only laterally, ie in the axial tung RICH, are guided by the outer winding layer of the respective winding ⁇ portion to the inner winding layer of the adjacent winding portion.
- the ⁇ rich so cranked in said conductor hencenbe then serves as an inner winding layer of said adjacent winding portion.
- each winding section forms with the exception of the first winding ⁇ portion of the series circuit of a step portion.
- the first winding section forms the so-called start of the winding arrangement, via which the winding arrangement is connected, for example, to the phase connection of a transformer or a choke.
- the outer end of the first Wick ⁇ coupling portion is then in the step portion with the in- connected to the lower end of the subsequent winding section in the axial direction, so that this is then the first winding ⁇ section having a step area. This applies correspondingly to the subsequent winding sections in the axial direction.
- each disk winding outside the step region forms an annular ring section.
- each disk winding is arranged in alignment with the next but one disk winding.
- the entire winding arrangement forms eccentric bulges only at two locations. This also simplifies the adjustment of the winding arrangement and their subsequent handling.
- the angle ⁇ is 180 degrees.
- the bulges lie opposite one another on different sides of the coil assembly. Deviating from this, the angle ⁇ is in the range of 10 to 30 degrees.
- both bulges are arranged on the same side of the winding arrangement, for example in front. In this way it is possible to limit a Lei ⁇ terfreiraum, which serves to receive inlets or outlets.
- any type of conductor can be used in the context of the invention.
- the conductor is a drawn wire conductor or a flat foil conductor.
- the winding arrangement is part of a transformer or a coil or choke.

- Said conductor 2 is wound, so that the layers of the conductor 2 in a layer are spirally stacked. These spirally superimposed interconnects are referred to here as winding layers.
- the first winding layer therefore limits a winding interior, which is referred to here as section interior 11.
- the superposed winding layers lie one above the other in a layer. In other words, the winding layers form disk-shaped disk windings 3a, 3b, 3c... 3n as a winding section.
- the winding sections are arranged one behind the other in the axial direction 4.
- the disc windings 3a, 3b, 3c ... 3n are all arranged at a distance D from each other, wherein the distance D may be different.
- the distance between the disk windings 3a and 3b is smaller than the distance between the disk windings 3b and 3c.

- the disk winding 3b is raised relative to the disk winding 3a in the radial direction 9 in the region of the connection from 6a to 5b so that its inner end 5b is at the same "radial" height as the outer Therefore, in the context of the invention, the conductor 2 only has to be bent or bent in the axial direction 4 out of the "layer" of the disk winding 3a in order to form the layer of the to be transferred to adjacent disc winding 3b. There it forms the first winding layer.
- the other Wick can ⁇ development were to be wound in the same direction by simply wrapping Next. A long conductor connection between the winding sections 3a, 3b, 3c... 3n as in FIG. 1 is therefore avoided in the context of the invention.
- the winding direction 7 is the same for all disk windings 3a, 3b, 3c... 3n.
- the disc windings 3a, 3b, 3c ... 3n can be arranged with a small distance D to each other, whereby the production of the winding assembly 8 remains cost-effective.

- the interior 14 contains quasi the aligned portion interior 13th
- the interior 14 is used to receive a magnetizable material which is adapted to guide a magnetic field with low magnetic resistance.
- the individual ticket ⁇ benwicklept 3a, 3n 3b, 3c ... are not circular in plan view and, therefore, limit individually not have a circular section inner chamber 13. Rather, each disc winding 3a, 3b, 3c ... 3n has an eccentric staged portion 10a, 10b, 10c ... 10 ⁇ on, which has a larger distance to an imaginary central axis of the circular cylindrical interior space 14 of the winding assembly 8 ⁇ than the verblei ⁇ Bende portion of each disc winding 3a, 3b, 3c ... 3n, which follows in a plan view of a circular shape.
- step region 10a is not arranged in alignment with the step region 10b of the disk winding 3b, which immediately follows the first disk winding 3a in the axial direction. Rather, the step portion 10b is circumferentially offset with respect to the step portion 10a, so that the two centers of the stepped portions 10a and 10b with each other be ⁇ xx the imaginary center axis of the inner space 14 of the winding assembly 8 to split an angle. Furthermore, it can be seen that the step region 10c of the next but one disk winding 3c is arranged in alignment with the step region 10a of the first disk winding 3a. This applies correspondingly to the step areas 10b and 10d. Each disk winding 3a, 3b, 3c ... 3n is therefore provided with its step portion 10a, 10b,

In this view it can be seen particularly well in that the disc windings are arranged in alignment to each other. In FIG. 7, it can be seen that the step regions 10 ⁇ and 10n-1 of the disk windings 3n and 3n-1 form an angle with one another with respect to the center of the circular-cylindrical internal space 14.
- the circular cylindrical interior 14 is schematically indicated by a dashed circle ⁇ te. It can be seen that the interior 14 is not completely circular cylindrical. Rather, due to the angle between here 20 degrees, an additional routing space 19 is formed, which can serve to receive conductors, cables, terminals and the like, when, for example, an underwinding and a leg of a core extends in the circular cylindrical interior.
- Figure 8 shows a further embodiment of the OF INVENTION ⁇ to the invention winding assembly 8, which differs from that shown in Figure 7 embodiment in that the angle which the step portions 10 ⁇ and 10n-l span with respect to the center axis of the circularly cylindrical inner space 14 MITEI ⁇ Nander, 180 ° is. It can be seen that in this embodiment, the inner contour of the disc windings together limit the circular cylindrical interior, so that a more compact winding arrangement without additional space, as shown in Figure 7, for cable management.
