Bobbin circumference segment, bobbin, coil and assortment

Field of technology

According to a first aspect, the present invention relates to a coil core peripheral segment, according to a second aspect to a coil core, according to a third aspect to an assortment of components for the assembly of coils, according to a fourth aspect to a coil core and according to a fifth aspect a coil.

State of the art

Coils are important in numerous technical applications when winding, storing and unwinding winding material, such as tapes, foils, paper, yarn, etc., too. Conventionally, a reel has a reel core and one or two adjoining reel flanges which protrude radially outward beyond the reel core to form the lateral edge of a space for winding material. In the case of coils known in the prior art, the coil core is made in one piece, and the coil flange or flanges are also made in one piece on the coil core. Thus, in a conventional coil, the outer diameter of the coil core and the outer diameter of the coil flanges are fixed. While coils allow space-saving storage of winding goods, on the other hand it is perceived as a disadvantage that, especially with varying requirements, the user needs a lot of space for the storage and transport of coils. This is associated with undesirably high costs and is particularly beneficial for users who need coils for various applications that differ in their dimensions, in particular in the outer diameters of the coil core and / or the coil flanges. Summary of the invention

Against this background, the invention is based on the object of advantageously developing coils. In particular, the invention is based on the task of specifying possibilities and developing coils in such a way that the disadvantages described above can be avoided as far as possible, in particular completely.

To achieve the object, the invention proposes, according to its first aspect, a coil core circumferential segment which comprises: a first assembly side and a second assembly side, the first assembly side having at least one side surface that spans a first reference plane and at least one assembly means , wherein the second assembly side has at least one side surface that spans a second reference plane, and at least one assembly means, the first reference plane and the second reference plane together enclose a circumferential segment angle, the at least one assembly means of the first assembly side either having a recess. has, the one adjacent to the side surface of the first mounting side

Has opening and which extends from the opening into the Spulenkernum catch segment, wherein in a cross-sectional plane perpendicular to the first reference plane in relation to a width direction parallel to the first reference plane, an opening width of the opening is smaller than a maximum width of the recess, or a Has projection which has a surface adjacent to the side of the first assembly side approach and which extends away from the approach starting from the first reference plane, wherein in a cross-sectional plane perpendicular to the first reference plane in relation to a width direction parallel to the first reference plane a neck width of the approach is smaller than a maximum width of the projection, and wherein the at least one mounting means of the second mounting side either has a recess from the one to the side surface of the second mounting side has adjacent opening and which extends from the opening into the Spu steering core segment, wherein in a cross-sectional plane perpendicular to the second reference plane in relation to a width direction parallel to the second reference plane, an opening width of the opening is smaller than a maximum width of the recess, or a Has projection which has a shoulder adjacent to the side surface of the second assembly side and which extends from the shoulder starting from the second reference plane directed away, wherein in a cross-sectional plane perpendicular to the second reference plane in relation to a parallel to the second reference plane width direction a The approach width of the approach is smaller than a maximum width of the projection. Such coil core circumferential segments can be detachably connected to one another in suitable numbers by means of their assembly means, so that a coil core results whose core shell extends over a circumference of 360 degrees. It has been found to be advantageous that the coil core circumferential segments required for the construction of one or more coil cores require less space for storage and transport compared to a corresponding number of coil cores. This is made possible by the fact that the coil cores for storage and transport can be broken down into core circumference segments, which can then be relocated individually relative to one another until a desired pack size is obtained. It can thus be achieved that a larger number of dismantled coil cores can be accommodated in a given storage or transport space compared to complete coil cores.

There are numerous options for preferred further training:

There is the possibility that the mounting means of the first Mon day side has the recess and that the mounting means of the second mounting side has the projection. The approach width is preferred Projection less than or equal to the opening width of this recess, and the maximum width of this projection is less than or equal to the ma ximal width of this recess and greater than the opening width of this recess. In this way, by means of a recess and a matching projection, a positive engagement for connecting two adjacent coil core circumference segments can be achieved. It is preferred that a connection that can be established by means of the two assembly means can then be released again if necessary. Particularly preferred is the possibility that the assembly means that form a connection with one another can be separated again in a non-destructive, preferably damage-free manner, so that connections can be established and released several times.

It is considered expedient that the circumferential segment angle of each individual coil core circumferential segment is an integral fraction of 360 degrees, in particular 15 or 30 or 40 or 60 or 90 or 120 or 180 degrees. Alternatively or in combination, there is the possibility that on the first and the second assembly side the respective assembly means are integrally formed on the coil core circumferential segment, that is to say in one piece, or are fixedly attached to the coil core circumferential segment.

Mounting means on the first mounting side and mounting means on the second mounting side of a respective spool core circumference segments are preferably matched in terms of position and in their shape and size so that a first mounting side of a first spool core circumference segment with a second mounting side of a second identical spool core circumference segment means the respective mounting means can be connected without conventional loose connecting means, such as screws, being required. It is also preferred that a cross-sectional contour of the recess of the mounting means of the first mounting side and a cross-sectional contour of the front of the projection of the mounting means of the second mounting side can be aligned relative to each other in a projection on each other so that the cross-sectional contour of this projection completely or the cross-sectional contour of this recess while leaving a gap running along the edges of the cross-sectional contours. This advantageously makes it possible, by means of the assembly means, to produce a connection between adjacent coil core circumference segments that is almost or completely free of play, at least in relation to certain directions.

With regard to the shape, there is, inter alia, the possibility that the projection and the recess each have a rotationally symmetrical shape, the projection, for example. Mushroom-like and the recess is adapted in its shape, so that, in particular also depending on the respective deformability of the selected material, a locking plug connection can be provided.

Regarding the shape, however, it is preferred that the recess of the mounting means on the first mounting side is designed as a groove and the projection of the mounting means on the second mounting side is designed as a bar. By means of a groove and a bar (the latter is also referred to as a tongue), the profiles of which are undercut to match one another in a cross-sectional plane, adjacent coil core circumferential segments can be releasably connected by inserting the bar into the groove, starting at one longitudinal end until the bar is as completely as possible in the groove. To release, the bar can be removed from the groove again by means of a longitudinal movement. With a groove and a bar it is also advantageous that adjacent coil core circumferential segments can be connected not only selectively, but over a desired length.

There is the possibility that a cross-sectional contour of the recess of the mounting means of the first mounting side and a cross-sectional contour of the projection of the mounting means of the second mounting side each have the same shape, the shape having a rounded round or trapezoidal section. This is suitable inter alia. to create an easily running and at the same time stable connection.

In an expedient further development it is provided that the spool core peripheral segment has a first peripheral segment surface and a second peripheral segment surface, the first peripheral segment surface between the edges of the first assembly side and the second assembly side which diverge according to the circumferential segment angle, and wherein the second extends Peripheral segment surface between the two remaining edges of the first assembly side and the second assembly side. It is preferred that, when assembling a coil core, several coil core circumferential segments are combined with uniform circumferential segment angles. The circumferential segment angle is expediently selected to be so large that a matching number of coil core circumferential segments can be connected to form a coil core that extends over 360 degrees.

Preferably, it is contemplated that the first circumferential segment surface extends along a geometric circular contour, it being provided in particular that a center point of the circular contour lies laterally next to an intersection line formed by the first reference plane and the second reference plane. As will be described in more detail, this advantageously enables an the coil core circumference segments laterally existing fastening means (for example threaded holes or threaded pins), which are suitable for attaching coil flanges to the coil core, can lie on straight geometric lines that extend radially from a geometric center axis of the coil core.

There is the possibility that on the first assembly side a wide re groove or several further grooves is or are present, which is or are laterally spaced from the at least one groove and which is or in particular formed the same as the at least one groove and that on the second assembly side there is or are a further bar or bars which are or are laterally spaced from the at least one bar and which, in particular, is or are designed identically to the at least one bar, and / or that one or more further side surfaces are formed on the first assembly side, which are spaced apart from one another by the grooves, and that on the second assembly side one or more further side surfaces are formed which are spaced apart from one another by the strips. This favors a two-dimensional, almost flat and therefore particularly stable connection between two adjacent coil core circumference segments.

In a preferred embodiment it is provided that in a to the first reference plane and to the second reference plane perpendicular to the third reference plane, the lateral distances of the grooves from the edge of the first assembly side adjacent to the first circumferential segment surface to the lateral distances of the strips of the the edge of the second assembly side adjoining the first circumferential segment surface are adapted so that a second, identical coil core circumferential segment can be monüerbar on the first assembly side of the coil core circumferential segment by having one bar of the two th bobbin circumference segment can be pushed into one groove of the bobbin circumference segment, and so that a third, identical bobbin circumference segment can be mounted on the second assembly side of the spool core circumference segment by inserting a bar of the bobbin circumference segment into each groove of the third bobbin circumference segment. This advantageously makes it possible for all of the coil core circumferential segments intended for the assembly of a coil core to be designed to be uniform with respect to one another.

It is also preferred that the coil core peripheral segment is made in one piece from plastic, in particular in the plastic injection molding process.

There is the possibility that the spool core peripheral segment has an annular wall that borders a cavity and on which the first side surface, the second side surface, the mounting means of the first mounting side and the mounting means of the second mounting side are formed. In comparison to a construction without another cavity, a weight saving can advantageously be achieved.

Furthermore, it is preferred that the coil core peripheral segment has a first end face, the surface of which extends transversely to the side surface of the first assembly side and to the side surface of the second assembly side, that the coil core peripheral segment has a second end face opposite to the first end face, the surface of which runs parallel to the surface of the first end face that on the first end face and on the second end face along the second assembly side at a distance from each other a plurality of threaded bores and / or a plurality of threaded pins protruding beyond the respective surface of the end face are arranged and / or that on the first face and on the second face, each to the first circumferential segment surface adjacent, in a region between the first assembly side and the second assembly side each at least one threaded hole or at least one threaded pin protruding over the respective surface of the end face is arranged. Such threaded bores and / or threaded pins can be used for the detachable connection of coil flanges to a coil core formed from several coil core circumferential segments. There is the possibility that a respective threaded hole is formed directly in the coil core circumferential segment. If, on the other hand, a base body of the coil core circumferential segment consists of a material that is softer than a screw, such as plastic or wood or some other softer material, it is considered advantageous that a respective Threaded hole is formed in a threaded bushing, preferably made of metal, which is firmly inserted into the base body of the coil circumference segment.

In order to achieve the above-mentioned object, the invention, according to its second aspect, provides a coil core which has a plurality of coil core circumferential segments which each have one or more of the features described above. It is provided that in the assembled state of the coil core in the circumferential direction adjacent coil core circumferential segments are positively connected to one another by engaging the grooves of the respective coil core circumferential segment in the grooves of the one adjacent coil core circumferential segment and by engaging the grooves of the other adjacent coil core circumferential segment on the respective coil core circumferential segment , wherein the coil core circumference segments of the coil core are formed uniformly to one another. For possible effects and advantages, reference is made to the preceding description. There are also numerous possibilities for preferred further development with regard to a coil core according to the invention:

It is preferred, in the assembled state of the coil core, side surfaces of a first assembly side of a coil core circumferential segment and side surfaces of a second assembly side of an adjacent coil core circumferential segment are supported on one another. This favors a stable construction of the coil core. It is considered expedient that the circumferential segment angle of each individual coil core circumferential segment is an integral fraction of 360 degrees, in particular 15 or 30 or 40 or 60 or 90 or 120 or 180 degrees, and that the multiplication product of the number of the coil core circumferential segments Coil core and the circumferential segment angle of a respective coil core circumferential segment results in 360 degrees, it being provided in particular that all so-called second circumferential segment surfaces of the coil core circumferential segments extend along a circular core envelope surface.

There is the possibility that the respective so-called border the central opening of the coil core. This advantageously corresponds to a customary external shape, so that a coil core composed of several coil core circumferential segments does not differ from conventional one-piece coils for the application. The formulations first circumferential segment area and second circumferential segment area do not indicate a sequence, but serve to physical differentiation of the outer and inner circumferential segment surfaces in relation to a geometric central axis.

It is preferred that in the assembled state of the coil core circumferential segments center points of their end-face threaded pins and / or threaded bores are arranged on lines which run radially through the center point of the coil core. This simplifies assembly and disassembly as well as the standardization of hole patterns in coil flanges.

To achieve the object, the invention relates, according to a third aspect, to an assortment of components for assembling coils.

An assortment according to the invention contains at least as components: at least one first coil core according to the invention with a first outer diameter, at least one second coil core according to the invention with a second outer diameter that is larger than the first outer diameter, at least one coil flange or several coil flanges, the first coil core on each end face of its spool core circumferential segments has a first arrangement of threaded bores, the second coil core on each end face of its spool core circumferential segments each having a second arrangement of threaded bores, with every second arrangement having at least some or all of the threaded bores of the first arrangement on each to the first arrangement has the same positions, in particular the same positions in relation to a geometric center axis of the respective coil core and / or in relation to the first and second reference planes of the respective coil core circumferential segment and additionally has at least one further threaded hole, which is positioned in relation to a geometric center axis of the coil core at a greater radial distance than the threaded holes of the first arrangement, and wherein the at least one coil flange surrounds a plurality of through holes. has a comprehensive hole pattern, the hole pattern being matched to the first arrangement so that the coil flange can be aligned concentrically to the first coil core so that on the end face of each coil core circumferential segment of the first coil core each threaded hole or at least part of the threaded hole is posi on the end face facing the coil flange A through hole is appropriately assigned in terms of function, and the hole pattern is matched to the second arrangement in such a way that the coil flange can be aligned concentrically to the second coil core, so that on the end face of each coil core facing the coil flange, each coil core has a circumferential segment of the second coil core Threaded hole or at least a part of the threaded holes is assigned a through hole in a positionally fitting manner. In this respect, the invention proposes a detachable assembly with regard to the reel flanges. By means of the features specified for this purpose, the positions of threaded holes and / or threaded pins on the one hand and through holes on the other hand in the sense of a system concept are coordinated so that different coil cores can optionally be combined with the same or differently dimensioned coil flanges. The range can, for example, also contain different Spu lenflansche, which differ in their outer diameter from each other, but which can have the same hole patterns and thus can be interchanged on the coil cores. Thus, a large number of different coils can be put together from a comparatively small range of coil cores or coil core peripheral segments and coil flanges, depending on requirements and the application. This reduces the space required for storage and transport and the costs associated therewith in practice.

The idea described can be continued, for example, for an assortment that has at least one third coil core with a third outer diameter, the third diameter being greater than the second Diameter, the third coil core having a third arrangement of threaded bores on each end face, each third arrangement having at least some or all of the threaded bores of the second arrangement at the same positions as the second arrangement and additionally having further threaded bores, which in Are positioned with respect to a geometric center axis of the coil core radially outside of the second arrangement. Also in a continuation of the idea, the hole pattern of the coil flange can be matched to the third arrangement in such a way that the coil flange can be aligned concentrically to the third coil core so that on the end face of the third coil core facing the coil flange each threaded hole or at least one part the threaded holes are assigned a through hole in a matching position.

According to a further aspect, the present invention comprises a plurality of coil core circumferential segments having the coil core, each coil core circumferential segment having a first, outwardly facing first circumferential segment surface on the coil core and extending along a respective circumferential segment angle, wherein on the coil core circumference Segments mounting means are fixed, in particular in one piece, formed or fixedly attached, by means of which the coil core circumference segments are releasably connected to one another or can be releasably connected to one another. This advantageously enables a simple assembly of a plurality of coil core circumferential segments to obtain a coil core and, if necessary, a simple dismantling of the coil core. It is considered advantageous that accessory-free assembly and disassembly is possible, ie that no conventional loose connecting material such as screws, rivets or the like is required, so that no conventional tools such as screwdrivers, riveting tools or the like, are required. Also for a coil core according to this further aspect of the invention there are numerous possibilities for preferred further training fertilize For example, one or more features that are described in connection with other aspects of the invention can also be implemented on such a coil core.

According to a still further aspect, the present invention comprises a spool which comprises at least one spool core according to the invention and one or two spool flanges. To this end, the invention proposes that the coil flange has a hole pattern comprising a plurality of through bores, which is matched to an arrangement of threaded bores and / or threaded pins on at least one of the two end faces of the coil core, the coil flange being screwed to the coil core by passing screws through through-bores and screwing them into threaded bores or by passing threaded pins through through-bores and screwing nuts onto ends of the threaded pins protruding through through-bores, in particular providing that the coil has a second coil flange that is attached to one of the first coil flange is screwed on the other of the two end faces of the coil core in a corresponding manner. This advantageously enables a detachable fastening of coil flanges to a coil core formed from several coil core circumferential segments, so that an overall modular coil structure results. Another advantage can be that the lateral attachment of coil flanges to a coil core also enables effective protection against inadvertent movement of coil core circumferential segments relative to one another, in particular in a lateral direction.

DESCRIPTION OF THE EMBODIMENTS FIGS. 1 and 2 show a coil core 1 according to the invention in accordance with a first preferred embodiment. This one is out of four Coil core circumferential segments 2 according to the invention, which are identical to one another, are assembled according to the first exemplary embodiment also shown in FIGS. 3 to 6 without the aid of loose fastening means, for example screws or the like. As illustrated in particular in FIG. 3, each coil core circumferential segment has a first assembly side 3 and a second assembly side 4, on which it can be detachably connected to adjacent, respectively constructed coil core circumferential segments 2. On the first assembly side 3, four adjacent, in the example each flat side surfaces 5 are formed, which lie in a common geometric, ie imaginary, reference plane E1, the reference plane E1 extending beyond the edges of the side surfaces 5. In this respect, the position of the reference plane El is spanned identically by each of the side surfaces 5, that is, determined geometrically. The reference plane El is shown schematically in Figure 4 Darge. In the example, four side surfaces 6 are formed on the second assembly side 4, which lie in a common reference plane E2, see also FIG. 4. As can also be seen in FIG 90 degrees. Accordingly, the coil core shown in FIGS. 1 and 2 is composed of four such coil core circumferential segments 2. For solvable connection with adjacent coil core circumferential segments 2, three mounting means 7 are integrally formed on the first mounting side 3 in the example. On the second assembly side 4, three assembly means 8 are also formed integrally, that is to say in one piece on the coil arm circumferential segment 2. In the example, a mounting means 7 is located between two mutually adjacent side surfaces 5 and a mounting means 8 is located between each two adjacent side surfaces 6.

In the selected embodiment, ie not necessary, the assembly means 7 arranged on the first assembly side 3 are identical to one another, the assembly means arranged on the second assembly side 4 are means 8 are identical to one another and the three mounting means 7 are designed differently from the three mounting means 8.

Each mounting means 7 has a recess 9, which is designed as a groove 10, which extends in its longitudinal direction parallel to a line of intersection S common to the reference planes E1 and E2, and in a state mounted to a coil core 1 (cf. 2) parallel to its geometric central axis M. Each recess 9 has an opening 11 bordered by two side surfaces 5 and extends in its longitudinal direction parallel to the cutting line S and transversely to its longitudinal direction from the opening 11 into the coil core circumferential segment 2. In a cross-sectional plane perpendicular to the first reference plane El, for example in the plane of the drawing in FIG. 4, an opening width a of the opening 11 is smaller than a maximum width b of the recess 9 in relation to a width direction B1 parallel to the first reference plane El. The recess 9 thus forms a groove 10 with an undercut in cross section.

Each mounting means 8 has a projection 12 which has a shoulder 13 adjacent to two side surfaces 6 (one could also speak of a base 13). In the example, the projection is designed as a strip 14 which is formed integrally, that is to say in one piece, on the coil core circumferential segment 2 and which extends parallel to the cutting line S in its longitudinal direction. In relation to a cross-sectional plane perpendicular to E1 and E2 (see FIG. 4), the projection 12 extends from its extension 13 starting from the second reference plane E2, in the example perpendicular to the reference plane E2. With respect to a width direction B2 parallel to the second reference plane E2, an attachment width c of the attachment 13 is smaller than a maximum width d of the projection 12. The approach width c of the projection 12 is slightly smaller than the opening width a of the recess 9. The maximum width d of the projection 12 is slightly smaller than the maximum width b of the recess 9, but larger than the opening width a of the recess 9. The illustration shows that the shape and dimensions of the recesses 9 and the projections 12 are matched to one another so that several identically designed coil core circumference segments 2 can be detachably connected to form a coil core 1 (see also the figures 1, 2 and 6), in that the strips 14 of a respective coil core circumferential segment 2 engage in grooves 10 of the one adjacent coil core circumferential segment 2 and in that the 10 strips of the other adjacent coil core circumference segment 2 engage in its grooves on the coil core circumferential segment 2 under consideration. For this purpose, in a third reference plane E3 perpendicular to the first reference plane E1 and to the second reference plane E2 (this runs parallel to the plane of the drawing in FIG the first circumferential segment surface 15 adjoining edge 17 of the first assembly side 3 the lateral distances u, v, w of the strips 14 (based on the center of the strips) from the edge 18 of the second assembly side 4 adjoining the first circumferential segment surface 15.

In the example, the coil core peripheral segments 2 are each produced in one piece using the plastic injection molding process. The line denoted by 23 in FIG. 3 marks the boundary between two mutually inclined drafts. As the enlarged detail of FIG. 2 shows, the cross-sectional contour of the recess 9 and the cross-sectional contour of the projection 12 have the same rounded shape in order to achieve a form-fitting engagement that is practically free of play. With regard to a coil core circumference segment 2, it is provided that a cross-sectional contour of a recess 9 and a cross-sectional contour of the projection 12 are projected onto one another can be aligned relative to one another in such a way that the cross-sectional contour of the projection 12 fills the cross-sectional contour of the recess 9 with only a small edge gap in order to achieve a transition or clearance fit.

The coil core peripheral segment 2 shown in Figures 2 to 4 be seated a first peripheral segment surface 15, which on a coil core 1 (see FIG pointing radially inward. Correspondingly, the first circumferential segment surface 15 extends between an edge

17 of the first assembly side 3 and an edge 18 of the second assembly side 4, these edges 17, 18 being further spaced from one another due to the circumference segment angle a compared to the two other edges 19, 20 opposite on the respective assembly sides 3, 4 and therefore also known as diverging edges. The second peripheral segment surface 16 he stretches between the edge 19, which is on the opposite side of the edge 17 of the first mounting side 3, and the edge 20, which is on the edge

18 opposite side of the second assembly side 4 is located. The edges 17, 18 and 19, 20 run parallel to the cutting line S. The first circumferential segment surface 15 extends along a geometric circular contour K, which is indicated schematically in FIG. In the assembled state of the coil core circumferential segments 2, their respective circumferential segment surfaces 15 extend along the same circular contour K, the center of which lies on the central axis M indicated in FIG. 2 (this runs perpendicular to the plane of the drawing). In the example, the geometry of the coil core circumferential segments 2 is selected so that in the plane of the drawing in FIG. This advantageously enables the threaded bores 21 present on the end face of the coil core circumferential segments 2 in the assembled state of the coil Handlebar peripheral segments 2 are arranged on lines 22 which run radially through the geometric center axis M of the coil core 1.

In the embodiment described, the coil core peripheral segment 2 comprises a base body in the form of a wall 25 bordering an inner cavity 24. The wall 25 runs closed along a circumference of the cavity 24 so that it is an annular wall 25. This has an essentially uniform wall thickness along its entire course. The first side surfaces 5, the second side surfaces 6, the mounting means 7, 8, and also the first and second circumferential segment surfaces 15, 16 are formed on the outer side of the wall 25 facing away from the cavity 24. A surface 26 of a first end face 27 runs in planes perpendicular to the reference planes E1, E2 and a surface 28 of a second end face 29 runs on the opposite side of the coil core circumferential segment 2. The first end face 27 and the second end face 29 are along the second assembly side 4 a plurality of threaded bores 21 are introduced at intervals from one another. Furthermore, a further threaded hole 30 is made in the first end face 27 and in the second end face 29, each adjacent to the first circumferential segment surface 15, centrally between the first assembly side 3 and the second assembly side 4.

As FIGS. 7 to 10 show, the threaded bores 21, 30 are intended to screw two coil flanges 32, 33 to the end faces 27, 28 of the coil core circumference segments 2 of the coil core 1 for assembling the coil 31 shown in FIG . In this case, the front reel flange 33 in the viewing direction is shown transparently in FIG. 7 for the sake of illustration. It is also clear that on the coil core 1 the first circumferential segment surfaces 15 of adjacent coil core circumferential segments 2 border one another without gaps, so that a continuous cylindrical coil core jacket results. animals. FIG. 7 also shows that the second circumferential segment surfaces 16 of adjacent coil core circumference segments 2 together border a central opening 34 which can serve to accommodate an axle, a shaft or the like.

FIG. 9 shows a top view of the reel flange 33 shown transparently in FIG. 7. Its outer diameter is, as FIG the like is formed. The coil flange 33 has numerous through bores, of which the through bores 21 'are posi tioned assigned to the threaded bores 21 of the bobbin core 1 and of which the through bores 30' are positionally assigned to the threaded bores 30 of the bobbin core 1. Correspondingly, the through bores 21 'are arranged along lines 22' which intersect at right angles in a center Z. The partial section in FIG. 10, in conjunction with the partial section of FIG. 5, shows that the threaded bores 21 in the selected example are located in the interior of threaded sockets 35 made of metal, which are firmly inserted into bores opening into the end faces 27, 29 of the coil core circumference segment 2 are. In order to detachably connect the reel flanges 32, 33 to the reel core 1, a screw 38 is inserted through each through hole 21 'from the outside and screwed with its threaded end into the threaded hole 21 so that the reel flanges 32, 33 firmly against the end faces 27, 29 are pressed. Accordingly, screws 38 are also inserted through through-bores 30 ', which each fit a threaded hole 30 of a coil core circumference segment 2, and screwed into the respective threaded hole 30.

For releasable fastening of the reel flanges 32, 33, they can be aligned on the end faces 27, 29 so that the threaded pins 36, 37 protrude through the through bores 21 'and 30' and nuts (not shown in the figures) are screwed onto the threaded ends will.

FIG. 11 shows a perspective view of a coil core circumference segment 2 according to the invention in accordance with a second exemplary embodiment. As in the following figures, details and features that correspond to those from the previous figures are labeled with the same reference numerals for clarity. For comparison, FIG. 12 shows the coil core circumference segment 2 shown in FIG. 11 in solid lines and the coil core circumference segment 2 according to the first exemplary embodiment shown in FIGS. 3 and 4 with dashed lines. From the comparison it becomes clear that the coil core circumference segment 2 according to the second embodiment has a smaller outer diameter than the coil core circumference segment 2 according to the first embodiment. As a result, compared to the first exemplary embodiment, the number of side surfaces 5, 6 and mounting means 7, 8 in the coil core circumferential segment 2 according to FIG. 11 is reduced. The number of threaded bores 21 is also reduced. In the respective, assembled into a coil core 1 state (see Figure 12), the center points of the threaded holes 21 in both embodiments along the fin 22, the intersection of the geometric center axis M will run through. Starting from this point of intersection, which forms the center of the circular contour K, there is a threaded hole 21 at every distance in the circumferential segment 2 of the second embodiment on the coil core there is also a threaded hole 21 on the coil core peripheral segment 2 of the first exemplary embodiment, so that the hole patterns overlap with a suitable alignment. In addition, according to the first exemplary embodiment, each coil core peripheral segment 2 has an additional threaded bore 21 located radially further outward.

FIG. 13 shows in perspective a coil core circumferential segment 2 according to the invention in accordance with a third exemplary embodiment. FIG. 14 shows a schematic comparison with the coil core circumferential segments 2 of the first and second exemplary embodiments, each having a larger outer diameter. Each coil core peripheral segment 2 of the third exemplary embodiment has only three threaded bores 21 per end face 27, 29 along the second assembly side 4. In the same positions, i.e. H. at the same distance from the geometric central axis M, there are also threaded bores 21 on the coil core peripheral segments 2 of the first and second embodiment, for example. These two coil core circumferential segments 2 also have further threaded bores 21 adjacent to the second assembly side 4, each at a greater distance from the geometric center axis M.

From the foregoing it follows that the arrangement of the threaded bores 21 on the bobbin circumferential segment 2 of the third embodiment is, for example, compatible with those of the first and second embodiments. The reel flange 33 shown in FIG. 9 (and also the reel flange 32) contains a through-hole 21 adapted to this in position (i.e. in position and distance relative to the geometric center axis M) for all of the threaded bores 21 shown in FIG. 14 the coil flanges 32, 33 are compatible with the coil core peripheral segments 2 according to the first, second and third exemplary embodiments. In this respect, the coil core circumference segments 2 of the three exemplary embodiments, which are schematically compared with one another in FIG. 14, in conjunction with a coil flange 32, 33 or with two coil flanges 32, 33 also form an exemplary embodiment of an assortment of components according to the invention for assembling coils 31.

FIG. 15 shows a representation comparable to FIG. 8. Here, in Figure 15, an inventive coil core 1 according to the third exemplary embodiment (i.e. with the comparatively smallest outer diameter) is screwed to the two coil flanges 32, 33, while the same coil flanges 32, 33 in Figure 8 with a coil core 1 according to the first embodiment example, d. H. with the largest outside diameter, are screwed.

FIG. 16 shows schematically in a top view a preferred option for space-saving storage of a plurality of coil core circumference segments 2 on a pallet 39 which has a standardized base area. In the example, a number of eight coil core circumferential segments 2 was chosen according to the second exemplary embodiment. The illustration shows that the coil core circumference segments 2 can be arranged in a detached state on the base of the pallet 39 in such a way that they do not protrude outward beyond their outer edge. It can also be seen that the coil core peripheral segments 2, on the other hand, in an assembled state in which they are joined together to form two coil cores 1, could not be placed on the pallet 39 without protruding beyond its outer edge. To show this, two circular contours 40 are indicated in dashed lines, which have the outer diameter of coil cores, which can be composed of segments 2 from the coil core circumference.
