UN TEL DISPOSITIF
La présente invention concerne un dispositif de bobines électriques à plusieurs positions de connexions.MULTI-POSITION ELECTRIC COIL DEVICE
CONNECTION AND E-ELECTRIC MOTOR USING
SUCH A DEVICE
The present invention relates to an electrical coil device with several connection positions.

L'invention concerne un moteur électrique à plusieurs positions de connexions statoriques. The invention relates to an electric motor with several positions of stator connections.

Dans l'art antérieur les fabricants de moteurs doivent adapter leurs fabrications aux demandes des équipements. Ceux-ci, en particulier, demandent- que les connexions des bobinages statoriques soient dans des positions différentes d'une commande à l'autre. La technique habituelle était de fabriquer un moteur spécialisé en fin de chaîne en vue de répondre à la demande. On a aussi proposé de rajouter un connecteur supplémentaire libre du moteur. Ces solutions limitent la standardisation ou augmentent le cott de fabrication. In the prior art engine manufacturers must adapt their manufacturing to the demands of the equipment. These, in particular, require that the connections of the stator windings be in different positions from one control to another. The usual technique was to manufacture a specialized motor at the end of the chain in order to meet demand. It has also been proposed to add an additional free connector of the motor. These solutions limit standardization or increase the cost of manufacturing.

La présente invention apporte remède à ces inconvénients de l'art antérieur. L'invention est particulièrement avantageuse pour tout dispositif constitué de bobines électriques quand il faut placer le dispositif dans des ensembles très différents les uns des autres pour ce qui est de la position des connexions. C'est le cas notamment des transformateurs statiques, des relais électromagnétiques, d'électrovannes, etc. En effet, elle concerne un dispositif de bobines électriques qui comportent au moins deux fils d'extrémité connectés à des premières cosses. Un premier est disposé au contact des premières cosses dans une position déterminée. Un capot de fermeture comportant plusieurs ouvertures est disposé en relation géométrique avec le bornier pour permettre de placer ces bornes dans la position géométrique désirée par des rotations déterminées. The present invention remedies these drawbacks of the prior art. The invention is particularly advantageous for any device consisting of electric coils when it is necessary to place the device in assemblies which are very different from each other as regards the position of the connections. This is particularly the case for static transformers, electromagnetic relays, solenoid valves, etc. Indeed, it relates to a device of electric coils which comprise at least two end wires connected to first lugs. A first is arranged in contact with the first lugs in a determined position. A closure cover comprising several openings is arranged in geometrical relation with the terminal block to allow these terminals to be placed in the desired geometrical position by determined rotations.

Elles concerne aussi un moteur électrique dont le bobinage statorique utilise un tel dispositif. They also relate to an electric motor whose stator winding uses such a device.

D'autres caractéristiques et avantages seront expliqués à l'aide des figures qui sont:
- la figure 1 un schéma de montage d'un moteur selon un mode préféré de réalisation;
- la figure 2 un schéma d'une plaquette interchangeable.Other characteristics and advantages will be explained using the figures which are:
- Figure 1 an assembly diagram of an engine according to a preferred embodiment;
- Figure 2 a diagram of an interchangeable plate.

Le moteur de la figure 1 est un moteur de type en U dont le stator 1 est obtenu par empilement de tôles d'acier à caractéristiques magnétiques en ménageant une fenêtre 3 et un alésage rotorique 2. Le bobinage statorique 4 est installé dans la fenêtre 3. The motor of FIG. 1 is a U-type motor, the stator 1 of which is obtained by stacking steel sheets with magnetic characteristics by providing a window 3 and a rotor bore 2. The stator winding 4 is installed in the window 3 .

Il comporte principalement un noyau de fer 11 et un bobinage 10, partiellement représenté, enserrés entre deux joues 8, 9. Un tel moteur est décrit ainsi que son procédé de fabrication dans le brevet français NO 2 483 700.It mainly comprises an iron core 11 and a winding 10, partially shown, sandwiched between two cheeks 8, 9. Such a motor is described as well as its manufacturing process in French patent NO 2 483 700.

Le bobinage statorique 4 est aussi muni de quatre chandelles (12-15) dont trois sont visibles au dessin. Ces chandelles servent de fixations à une plaquette 5 de support de composants de service du bobinage comme un protecteur thermique 19 disposé dans un logement 18. La plaquette 5 est encliquetée sur les chandelles 13 et 15 par les trous 20 et 21 percés sur son plateau. Dans cette position, la plaquette est disposée selon l'indication a de la flèche 24. La plaquette 5 peut être retournée de 180 selon l'indication b de la flèche 24 et les trous 20, 21 reçoivent les chandelles 12 et 14. The stator winding 4 is also provided with four candles (12-15), three of which are visible in the drawing. These candles serve as fasteners to a plate 5 for supporting winding service components such as a thermal protector 19 disposed in a housing 18. The plate 5 is snapped onto the candles 13 and 15 by the holes 20 and 21 drilled on its plate. In this position, the plate is arranged according to the indication a of the arrow 24. The plate 5 can be turned over by 180 according to the indication b of the arrow 24 and the holes 20, 21 receive the candles 12 and 14.

D'autre part, les joues 8 et 9 supportent des premières cosses 16 et 17 qui pénètrent dans les fentes 22 et 23 de la plaquette 5 qu'elle soit en position 24a ou 24b. Les cosses dépassent des fentes 22 et 23 de manière à pénétrer aussi sur un bornier 6 muni de fentes adéquates 27 et 28. Ce bornier porte ici deux bornes 26, 29 électriquement isolées et mécaniquement liées de manière à permettre une alimentation électrique convenable par l'extérieur. Le bornier 6 est représenté dans la position a de la flèche 26. La flèche 26 indique que le bornier 6 peut tourner autour d'un axe perpendiculaire à l'alignement des pièces représentées de façon à présenter vers le bas les bornes 29 et 26 quand la flèche 25 est en position b. On the other hand, the cheeks 8 and 9 support first lugs 16 and 17 which penetrate into the slots 22 and 23 of the wafer 5 whether it is in position 24a or 24b. The lugs protrude from the slots 22 and 23 so as to also penetrate a terminal block 6 provided with suitable slots 27 and 28. This terminal block here carries two terminals 26, 29 electrically isolated and mechanically linked so as to allow a suitable electrical supply by the outside. Terminal block 6 is shown in position a of arrow 26. Arrow 26 indicates that terminal block 6 can rotate around an axis perpendicular to the alignment of the parts shown so as to present terminals 29 and 26 downwards when the arrow 25 is in position b.

On remarquera que cette rotation n'affecte pas la connexion des fentes 27 et 28 aux premières cosses 16 et 17 du bobinage.It will be noted that this rotation does not affect the connection of the slots 27 and 28 to the first lugs 16 and 17 of the winding.

Enfin, on a représenté un capot 7 percé de trois ouvertures: - latérale 33; - supérieure 31, 32 - inférieure 34, 35. Finally, there is shown a cover 7 pierced with three openings: - lateral 33; - upper 31, 32 - lower 34, 35.

Dans le montage de la figure I, la borne 29 passe à travers l'ouverture supérieure 31 et la borne 26 à travers l'ouverture supérieure 32. In the assembly of FIG. I, the terminal 29 passes through the upper opening 31 and the terminal 26 through the upper opening 32.

A la figure 2, on a représenté un autre bornier qui permet de réaliser une connexion latérale contrairement au bornier 5. Ce nouveau bornier 40 peut remplacer selon la flèche 44, le bornier 6. In FIG. 2, another terminal block is shown which allows a lateral connection to be made unlike terminal block 5. This new terminal block 40 can replace, according to arrow 44, the terminal block 6.

Des fentes 42 et 43 permettent aussi la connexion aux cosses 16 et 17. Le bornier 40 est représenté en position latérale droite selon la flèche F d'alignement des pièces. I1 est alors en position a de la flèche 45.Slots 42 and 43 also allow connection to the lugs 16 and 17. The terminal block 40 is shown in the right lateral position according to the arrow F for aligning the parts. I1 is then in position a of arrow 45.

Par rotation en position b de la flèche 45 on peut disposer le bornier 40 en position latérale gauche à condition de tourner en position b le capot 7 autour de la flèche F selon la rotation 36. By rotation in position b of the arrow 45, the terminal block 40 can be placed in the left lateral position provided that the cover 7 is rotated in position b around the arrow F according to rotation 36.

Enfin quand le capot 7 est en position 36b, ouverture latérale tournée vers la gauche, soit la situation inverse de ceile de la figure 1, on peut tourner l'ensemble constitué par la plaquette 5 et le bornier de type 5 de 1800 en position b selon la flèche 24. Par asymétrie des bornes 29 et 26, ce retournement fait correspondre les nouvelles positions du bornier aux ouvertures 31, 32 ou 34, 35 retournées sur la position 36b du capot 7. Le même avantage est prévu sur le bornier 40. Finally when the cover 7 is in position 36b, lateral opening turned to the left, that is the opposite situation of that of Figure 1, we can turn the assembly constituted by the plate 5 and the type 5 terminal block of 1800 in position b according to arrow 24. By asymmetry of the terminals 29 and 26, this reversal makes the new positions of the terminal block correspond to the openings 31, 32 or 34, 35 returned to the position 36b of the cover 7. The same advantage is provided for the terminal block 40.

On obtient ainsi huit positions possibles des deux bornes: quatre positions verticales et quatre positions latérales à travers le capot selon les combinaisons possibles des rotations qui ont été décrites. Eight possible positions of the two terminals are thus obtained: four vertical positions and four lateral positions through the cover according to the possible combinations of the rotations which have been described.

Dans un autre mode de réalisation, le fond vertical 51 du capot sert de support et remplace le support 5, ce qui réduit les manipulations de pièces et leur nombre sans réduire le nombre des possibilités de connexion. In another embodiment, the vertical bottom 51 of the cover serves as a support and replaces the support 5, which reduces handling of parts and their number without reducing the number of connection possibilities.

L'invention se prête particulièrement par sa simplicité à une
automatisation complète des opérations finales de connexion élec
trique. The invention lends itself particularly by its simplicity to a
full automation of final electrical connection operations
stick.

On remarquera qu'un moyen important de l'invention est la constitution asymétrique des borniers et des ouvertures du capot relativement aux axes des rotations décrites ci-dessus. De plus, l'invention n'est pas limitée aux bobines statoriques constituées d'une seule bobine mais au cont.aire, il est possible dans le cadre de l'invention de multiplier les bornes d'accès électrique, les bornes pouvant pour un bornier être les unes au-dessus des autres et/ou les unes à côté des autres. Dans ce cas, les rotations ne sont plus nécessairement de 1800, mais dépendent des schémas de connexion désirée.  It will be noted that an important means of the invention is the asymmetrical constitution of the terminal blocks and of the hood openings relative to the axes of the rotations described above. In addition, the invention is not limited to stator coils consisting of a single coil, but to the content, it is possible within the framework of the invention to multiply the electrical access terminals, the terminals being able for one terminal block be one above the other and / or one next to the other. In this case, the rotations are no longer necessarily 1800, but depend on the desired connection diagrams.
