The coil body has a winding space limited by flanges and a flange recess facing a wedge-shaped catch nose arranged at a winding spindle of the winding mechanism. The catch nose is radially and resiliently movable against the coil body and engages the flange recess during winding such that the coil body being wound can be protected against turning.

Description
-~21 3627~
BACKGROUND OF THE INVENTION
The invention relates to an electrical coil body suitable for automatic delivery to a winding mechanism and for automatic winding. A winding space is provided which is limited by a ~lange, and which has a flange recess open toward the edge side into which a catch nose arranged at the winding spindle of the winding mechanism engages during winding. Thus, the coil body can be wound, and can be pro~ected against turning.
Coil bodies previously employed for automatic winding have flanges with slot-like seating surfaces aligned largely parallel to one another into which a rigid catch nose dips during winding. This catch nose is arranged parallel to the longitudinal axis of the winding spindle and is offset relative to the winding spindle. Under the influence of this catch nose the coil body is secured against turning relative to the winding spindle.
Flange breakage occurs to a considerable degree particularly when automatically equipping the winding mechanism with coil bodies having this type of design. Among the causes for this is the rigid alignment of the catch nose. Furthermore, the nature of the acceptance slots previously employed for the catch nose does not guarantee a positionally secured, i.e. a geometrically exact, arrangement of the terminal pins injected into the coil body flange for the winding wires. Upon automatic wrapping of t:he winding wires on these terminal pins which are not exactly aligned relative to one another, this likewise leads to production difficulties during winding and to production stoppages.
~J
~Z13627~
SUMMARY OF THE INVENTION
An object of the present invention is to create a coil body of the type initially cited by means of which flange breakage is avoidable, especially durin~ automatic winding, and which can also be locked or arrested such that during winding a reliable application of the wind:ing wires to the electrical terminal pins is possible.
In order to achieve th:is object in a coil body as above described, the invention provides that the flange recess at least at one section has seating surfaces for a wedge-shaped ~atch nose which can be moved radially and resiliently against the coil body.
The entire flange recess is preferably designed in wedge-shaped fashion.
As a consequence of this wedge-like formation of the flange recess, which should at least sectionally offer adequate seating surfaces for the likewise wedge-shaped catch nose, a reliable, i.e. quasi-elastic, and thus non-destructive, engagement of the resilient catch nose into the flange recess is always possible. Thus, given adequately large contact surfaces between the flange recess and the catch nose, a eomplete anti-twist fixing of the coil body on the winding spindle and thus a faultless application of the winding wires to the terminal pins is guaranteed.
Thus, in accordance with a broad aspect of the invention there is provided an electrical coil body winding system suitable for automatic delivery of electrical coil bodies to a winding mechanism having a winding spindle for automatic winding, comprising:
a coil body having a winding space limited by at least one flange;
g ~L2~276 a wedge-shaped recess in the at least one flange;
a wedge-shaped catch nose means arranged at the winding spindle of the winding mechanism for engaging in the recess during winding such that the coil body being wound can be protected against turning;
said recess being open toward the catch nose means and having seating surfaces for receiving the catch nose means; and the catch nose means being resiliently and radially movable against the coil body and into the recess in a direction perpendicular to a longitudinal winding axis of the coil body.
In accordance with another broad aspect of the invention there is provided an electrical coil body winding system for use with a winding mechanism, comprising:
a coil body having a winding region limited by at least one flange;
a V-shaped recess in the flange;
a catch nose means which is also V-shaped arranged at the winding mechanism for engaging in the V-shaped recess during winding so that the coil body being wound can be protected against turning; and the catch nose means being movable in a direction perpendicular to a winding axis of the coil body for play-free engagement in the V-shaped recess so as to precisely position the coil body in a desired rotational position without damaging the flange during engagement in the flange recess.
In accordance with another broad aspect of the invention there is provided a winding spindle system for winding a coil body having at least one flange with a wedge-shaped recess therein, comprising:
.~
:, ' ' ' ` '' ~ ' 'i ' 12~36Z7~i a winding spindle having a given winding axis; and a catch nose means having a wedge-shape and which is radially as well as resiliently movable in a direction perpendicular to the winding axis of the winding spindle and positioned so as to engage the f:Lange recess in the coil body in a play-free manner when the coil body is plugged onto the winding spindle.
Figure 1 shows a known design of a coil body employed 1~ for automatic winding comprising a catch nose, the winding spindle not being shown for the sake of clarity;
Figure 2 illustrates a first exemplary embodiment of a coil body of the invention in the same manner of illustration as Figure 1, whereby the catch nose is shown in cut-off fashion; and 3b 12t36Z76 Figure 3 is a further exemplary embodiment of a coil body of the invention, likewise in the same manner of illustration as in Figure 1, wherein the catch nose is likewise shown in cut-off fashion.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
, ;- A coil body referenced 1 in Figure 1 has flanges 2 having integral one-piece webs 5, 6 at one flange. These webs have wire guidance slots 7, 8 directed toward the winding space, and carry electrical wire terminal pins 9 which are injected in a defined geometrical alignment relative to one another.
The web-free flange 2 of this known design of a coil body has a flange recess 3 open toward the edge into which a catch nose 10 offset parallel to the longitudinal axis of the winding spindle engages during winding when the coil body is slipped onto a winding spindle. The anti-twist arrangement of the coil body 1 on the winding spindle (not shown) during windinq is guaranteed by this "engagementn.
The on-target "dipping~ of the catch nose 10 (guided perpendicular to the plane of the drawing) into the flange recess 3 mated to the contour of the catch nose presents difficulties in this embodiment. Occasional flange breakages given an inexact alignment of the flange recess 3 relative to the catch nose 10 are unavoidable with this embodiment. The possibility of widening the flange recess 3 such that the catch nose 10 is guided in the flange recess with play cannot be utilized since an exact alignment of the wire terminal pins 9 relative to the correspondincl winding elements of the winding mechanism is only assured given a tight fit of the catch nose 10 in the flange recess 3.
il6276 In the coil body 1 of Figure 2, the flange recess 3 of Figure 1 is replaced by a flange recess 11 which is likewise open toward the edge, but which is widened such that seating surfaces are present at least in sectiorls thereof. A catch nose 12 has parts of its end faces 13, 14 which taper in wedge-like fashion and press against these seating ~urfaces during winding. The catch nose 12, corresponding to the catch nose 10 of Figure 1, is likewise suitably aligned rela1:ive to the winding spindle (not shown) and can be radially moved to the coil body 1 in the direction of double arrow A. It is pressed against the flange recess 11 under the influence of a spring (not shown) during winding. Problems which occur given the coil body of Figure 1 are eliminated in this arrangement.
Figure 3 shows the preferred embodiment of such a coil body and of a corresponding catch nose. Here, a wedge-shaped flange recess 23 guarantees the completely breakage-proof engagement of a catch nose 20, likewise resiliently guidable in arrow direction A. It has wedge-shaped end faces 21, 22.
Although various minor changes and modifications may be suggested by those skilled in the art, it will be understood that I wish to include within the claims of the patent warranted hereon all such changes and modifications as reasonably come within my contribution to the art.
