Description

La présente invention est relative à un dispositif de bobinage pour un appareil électromagnétique dans lequel les enroulements sont réalisés par bobinage autour d'un noyau magnétique non coupe. L'invention s'applique notamment à la réalisation de transformateurs, cette application ne constituant toutefois qu'un exemple non limitatif. The present invention relates to a winding device for an electromagnetic device in which the windings are produced by winding around an uncut magnetic core. The invention applies in particular to the production of transformers, this application however constituting only a nonlimiting example.

A l'heure actuelle, lors des opérations de bobinage des enroulements autour d'un circuit magnétique a) soit on utilise des flasques amovibles, seulement pendant que s'effectue
l'opération de bobinage. On est alors obligé de prévoir des opérations de
montage et de demontage des flasques, et de prévoir en outre un espace
suffisant pour le passage de ces flasques, ces derniers étant remplacés,
après leur dépose, par des dispositifs de calage b) soit on utilise des flasques, constitues de matériaux isolants, qui restent
en place après le bobinage.
At the present time, during the winding operations of the windings around a magnetic circuit a) either removable flanges are used, only while the
the winding operation. We are therefore obliged to plan for
mounting and dismounting the flanges, and also providing space
sufficient for the passage of these flanges, the latter being replaced,
after their removal, by wedging devices b) either using flanges, made of insulating materials, which remain
in place after winding.

Dans les deux cas, on constate qu'il est nécessaire de prévoir un espace libre supplémentaire entre les flasques et le circuit magnétique, pour permettre le passage des connexions d'entrée et de sortie des enroulements. Par ailleurs, l'isolement de ces connexions est délicat à réaliser. Enfin, la néces- sité de prévoir ces espaces libres supplémentaires entrains un alourdissement du dispositif finalement obtenu, par sur-consommation d'éléments magnétiques. In both cases, it is found that it is necessary to provide an additional free space between the flanges and the magnetic circuit, to allow the passage of the input and output connections of the windings. Furthermore, isolating these connections is difficult to achieve. Finally, the need to provide these additional free spaces leads to an increase in the device finally obtained, by over-consumption of magnetic elements.

La présente invention se propose de réaliser un dispositif de bobinage ne présentant pas les inconvénients soulignés ci-dessus. Elle a pour objectif de réaliser un dispositif permettant de réaliser un bobinage autour d'un élément magnétique sans qu'il soit nécessaire de prévoir des espaces supplémentaires pour des flasques d'enroulement ou pour les Connexions, ce dispositif permet- tant, par ailleurs, d'effectuer un ajustement des spire s sans modification de l'ensemble. The present invention proposes to produce a winding device which does not have the drawbacks outlined above. Its objective is to produce a device making it possible to wind around a magnetic element without the need to provide additional spaces for winding flanges or for Connections, this device also making it possible to to make an adjustment of the turns without modifying the assembly.

Le dispositif selon l'invention est caractérisé en ce qu'il comporte deux flasques de bobinage, constitues chacun de deux demi-couronnes réalisées en matière conductrice, qui, après avoir été posées autour d'un élément magnétique fermé, sont assemblées selon leur ligne de raccordement, de telle manière que le premier flasque constitue le flasque d'entraînement pour le bobinage, la pre mière spire du bobinage et sa connexion d'entre'e, et que le deuxième flasque constitue le flasque d'entraînement pour le bobinage et sa connexion de sortie, l'une des extremites du matériau, bande ou fil conducteur, constituant le bobi
nage, étant reliée électriquement au flasque d'entrée de bobinage, et, à la fin de l'opération de bobinage, l'autre extrémité de ce matériau étant reliée électriquement au flasque de sortie du bobinage.
The device according to the invention is characterized in that it comprises two winding flanges, each consisting of two half-rings made of conductive material, which, after having been placed around a closed magnetic element, are assembled along their line connection, in such a way that the first flange constitutes the drive flange for the winding, the first turn of the winding and its input connection, and that the second flange constitutes the drive flange for the winding and its output connection, one of the ends of the material, strip or conductive wire, constituting the bobi
swimming, being electrically connected to the winding input flange, and, at the end of the winding operation, the other end of this material being electrically connected to the winding output flange.

D'autres caractéristiques et avantages de cette invention ressortiront de la description faite ci après en référence au dessin annexé, qui en illustre un exemple de réalisation dépourvu de tout caractère limitatif. Sur le dessin:
- la Figure 1 est une vue en perspective représentant un flasque du dispositif selon l'invention;
- la Figure 2 est une vue en perspective du premier flasque, qui constitue la connexion d'entrée du bobinage

- la Figure 4 illustre la façon selon laquelle on réalise l'entrée du bobinage, par pliage d'une bande conductrice ; et,
- la Figure 5 illustre la façon selon laquelle on réalise la sortie du bobinage.
Other characteristics and advantages of this invention will emerge from the description given below with reference to the appended drawing, which illustrates an embodiment thereof devoid of any limiting character. On the drawing:
- Figure 1 is a perspective view showing a flange of the device according to the invention;
- Figure 2 is a perspective view of the first flange, which constitutes the input connection of the winding
- Figure 3 is a perspective view of the second flange, which constitutes the winding output connection
- Figure 4 illustrates the way in which the input of the winding is produced, by folding a conductive strip; and,
- Figure 5 illustrates the way in which the output of the winding is produced.

Le dispositif selon l'invention réalise l'opération de bobinage autour d'un circuit magnétique en utilisant des flasques qui demeurent en place après le bobinage. En se référant à la Figure 1, on voit que chaque flasque 10 est constitué de deux demi-couronnes 12, 12', réalisées en matière conductrice présentant une bonne résistance mécanique, qui, après mise en place autour d'un élément magnétique fermé 14, sont assemblées, soit mécaniquement, soit par soudure, selon leur ligne de raccordement 16 (Fig. 2). The device according to the invention performs the winding operation around a magnetic circuit using flanges which remain in place after the winding. Referring to Figure 1, we see that each flange 10 consists of two half-rings 12, 12 ', made of conductive material having good mechanical strength, which, after placement around a closed magnetic element 14 , are assembled, either mechanically or by welding, along their connection line 16 (Fig. 2).

Le dispositif comporte donc deux de ces flasques, qui ont été désignes par les références 10a et lOb (Fig. 2 et 3). The device therefore comprises two of these flanges, which have been designated by the references 10a and 10b (Fig. 2 and 3).

Le premier flasque 10a constitue le flasque d'entrafneme nt pour le bobinage, la première spire de bobinage et la connexion d'entre du bobinage. Le second flasque lOb constitue le flasque d'entrarnement pour le- bobinage, la dernière spire de bobinage et sa connexion de sortie. The first flange 10a constitutes the entrafneme nt flange for the winding, the first winding turn and the input connection of the winding. The second flange 10b constitutes the drive flange for the winding, the last winding turn and its output connection.

Dans cet exemple de réalisation, l'enroulement est constitué par une bande conductrice 18 (il peut etre constitue par un fil conducteur, sans sortir du cadre de l'invention) qui, après pliage, est reliée Blectriquement au flasque d'entrée de bobinage 10a, dans la zone X. Le pliage de l'extremit de la bande 18 s'effectue de la façon représentée sur la Figure 4. On commence par rabattre l'extrémité de la bande 18, par pliage à 45D (Fig. 4a), puis on rabat à 90 la partie terminale de la bande (Fig. 4b), de manière à obtenir une languette 20, qui est fixée ensuite sur la zone X du flasque 10a. On effectue ensuite le bobinage de la bande entre les flasques 10a, 10b.En fin de bobinage, l'extrémité restante de la bande est de nouveau pliée (Fig. 5), mais à l'inverse du sens de pliage effectué au début du bobinage (Fig. 4), de manière à obtenir une languette 20' que l'on fixe, par exemple par soudures sur le flasque de sortie du bobinage lOb, dans la zone Z. In this exemplary embodiment, the winding is constituted by a conductive strip 18 (it can be constituted by a conductive wire, without departing from the scope of the invention) which, after folding, is connected electrically to the winding input flange 10a, in zone X. The folding of the end of the strip 18 is carried out as shown in FIG. 4. We begin by folding down the end of the strip 18, by folding to 45D (Fig. 4a) , then the end portion of the strip is folded at 90 (Fig. 4b), so as to obtain a tongue 20, which is then fixed on the area X of the flange 10a. The strip is then wound between the flanges 10a, 10b. At the end of the winding, the remaining end of the strip is folded again (Fig. 5), but unlike the direction of folding carried out at the start of the winding (Fig. 4), so as to obtain a tongue 20 'which is fixed, for example by welding on the output flange of the winding 10b, in the zone Z.

Selon l'invention, les flasques 10a et lOb peuvent etre munis d'ouvertures, de part et d'autre de la partie de ligne de raccordement restant libre 22, de manière à obtenir des zones de raccordement og et Y, pour le flasque d'entrée lOa, et Z et W, pour le flasque de sortie. According to the invention, the flanges 10a and 10b can be provided with openings on either side of the part of the connection line remaining free 22, so as to obtain connection zones og and Y, for the flange d 'input lOa, and Z and W, for the output flange.

Si le raccordement s'effectue dans la zone Y du flasque d'entrée et dans la zone Z du flasque de sortie, il existe autant de spire s qu'il y a de boucles dans l'enroulement. Si le raccordement s'effectue en X sur le flasque d'entrée, il faut prévoir une boucle (une spire) supplémentaire dans 11 enroulement, et Si le raccordement s'effectue en W sur le flasque de sortie, on prévoit une boucle ou spire supplémentaire. On a donc réalisé ainsi un moyen simple de réglage du nombre de spire s.  If the connection is made in zone Y of the inlet flange and in zone Z of the outlet flange, there are as many turns as there are loops in the winding. If the connection is made in X on the inlet flange, an additional loop (a turn) must be provided in 11 winding, and If the connection is made in W on the outlet flange, a loop or turn is provided additional. A simple means of adjusting the number of turns s has thus been produced.

Il demeure bien entendu que cette invention n'est pas limités aux divers exemples de réalisation décrits ou représentés, mais qu'elle en englobe toutes les variantes.  It remains to be understood that this invention is not limited to the various embodiments described or shown, but that it encompasses all variants thereof.
