These adaptation means may comprise at least one attachment heel which is intended to secure the association piece with the contactor device and / or the protective device and which has a variable position, in particular by being provided on a adjustable part fixed to the association piece, for example snap-fit on it in different positions offset in depth, and / or with support forms offset in height.

On comprend que la solution apportée permet de réduire le coût de l'ensemble interrupteur.It is understood that the solution provided reduces the cost of the switch assembly.

La description va être faite ci-après d'un mode de réalisation non limitatif de l'invention, en regard des dessins annexés.The description will be made hereinafter of a non-limiting embodiment of the invention, with reference to the accompanying drawings.

La figure 1 représente en vue de côté un ensemble de départ-moteur conforme à l'invention.The figure 1 is a side view of a motor starter assembly according to the invention.

Les figures 2 et 3 sont des vues en perspective à plus grande échelle de la pièce d'association de l'ensemble de la figure 1, la pièce étant représentée dans deux états permettant le montage de contacteurs de tailles différentes.The Figures 2 and 3 are perspective views on a larger scale of the piece of association of the whole of the figure 1 , the part being shown in two states allowing the assembly of contactors of different sizes.

Les figures 4 à 6 montrent en vue de côté une partie d'un ensemble selon l'invention, avec assemblage à un même disjoncteur de contacteurs de tailles différentes.The Figures 4 to 6 show in side view a part of an assembly according to the invention, with assembly to the same circuit breaker contactors of different sizes.

L'ensemble de la figure 1 comprend un disjoncteur 10 et un contacteur 20 assemblés au moyen d'une pièce intermédiaire 30. Le disjoncteur 10 peut être fixé à sa partie arrière à un support tel qu'un rail normalisé par des éléments de fixation 11 et comporte à sa partie avant des boutons marche et arrêt 12. Il présente par ailleurs des bornes de puissance amont (hautes) 13 et aval (basses) 14. Le contacteur 20 présente des faces arrière 21 et avant 22, ainsi que des bornes de puissance amont (hautes) 23 et aval (basses) 24. La pièce intermédiaire 30 est de forme relativement plate et comprend un corps isolant 31, ainsi que des conducteurs solidarisés avec le corps et reliés par des broches hautes 33 aux bornes basses 14 du disjoncteur et par des broches basses 34 aux bornes hautes 23 du contacteur. Les broches représentées sont fixes, mais elles pourraient être réglables pour s'adapter à des pas interbornes variables.The whole of the figure 1 comprises a circuit breaker 10 and a contactor 20 assembled by means of an intermediate piece 30. The circuit breaker 10 can be fixed at its rear part to a support such as a rail standardized by fastening elements 11 and comprises at its front part On the other hand, it has upstream (high) 13 and downstream (low) power terminals 14. The contactor 20 has rear faces 21 and front 22, as well as upstream (high) power terminals 23 and downstream (low) 24. The intermediate piece 30 is of relatively flat shape and comprises an insulating body 31, as well as conductors secured to the body and connected by high pins 33 to the lower terminals 14 of the circuit breaker and by low pins 34 to high terminals 23 of the contactor. The pins shown are fixed, but they could be adjustable to accommodate variable interbornes.

La pièce 30 est maintenue sur le disjoncteur par des éléments de retenue tels que des talons 32 coopérant avec des évidements 15, par exemple des fentes, prévus dans le boîtier du disjoncteur (voir figure 4), ainsi que par le serrage des broches 33 dans les bornes 14. Le contacteur est fixé sous la pièce 30 par un talon 35 prévu à l'arrière d'une pièce 36 encliquetée de manière réglable à l'arrière de la pièce 30, ainsi que par le serrage des broches 34 dans les bornes 23. Le réglage de la position de la pièce 36 permet d'ajuster la position du talon 35 selon la direction X, c'est-à-dire en profondeur.The piece 30 is held on the circuit breaker by retaining elements such as heels 32 cooperating with recesses 15, for example slots, provided in the circuit breaker housing (see FIG. figure 4 ), as well as by the clamping of the pins 33 in the terminals 14. The switch is fixed under the piece 30 by a heel 35 provided at the rear of a piece 36 snap-fitted in an adjustable manner at the rear of the piece 30, as well as by tightening the pins 34 in the terminals 23. The adjustment of the position of the piece 36 makes it possible to adjust the position of the heel 35 in the X direction, that is to say in depth.

La pièce amovible 36 est en forme d'équerre dotée d'une aile horizontale 37 de maintien dans la pièce 30 et d'une aile verticale 38 de support du contacteur. L'aile horizontale 37 est engagée contre un cran, butée ou appui analogue 36a,36b du corps 31 de la pièce 30 et l'aile verticale de support 38 est munie de deux crans ou autre formes analogues 39,40 sur laquelle doit s'accrocher la partie arrière du boîtier du contacteur. La pièce 36 est représentée en position reculée sur la figure 2 et en position avancée sur la figure 3, la butée 36b étant située plus en arrière que la butée 36a. Les deux crans 39,40 permettent le montage de nervures 25 ou autres formes du contacteur situées à une hauteur variable en fonction du type du contacteur par rapport à sa face haute 26 ; cette face haute 26 est définie par divers éléments de butée et elle est appliquée contre la face basse de la pièce 30. Les crans 39,40 permettent donc d'adapter la pièce d'association à la taille du contacteur selon la direction Z, c'est-à-dire en hauteur.The removable piece 36 is in the shape of a square provided with a horizontal flange 37 for holding in the piece 30 and a vertical flange 38 for supporting the contactor. The horizontal flange 37 is engaged against a notch, abutment or similar support 36a, 36b of the body 31 of the part 30 and the vertical support flange 38 is provided with two notches or other similar forms 39,40 on which must hang the back of the switch housing. The piece 36 is shown in a retracted position on the figure 2 and in advanced position on the figure 3 , the stop 36b being located further back than the stop 36a. The two notches 39,40 allow the mounting of ribs 25 or other forms of the contactor located at a variable height depending on the type of the switch with respect to its upper face 26; this upper face 26 is defined by various abutment elements and is applied against the lower face of the part 30. The notches 39,40 thus allow to adapt the association piece to the size of the contactor in the direction Z, c that is to say in height.

On voit sur la figure 4 le montage d'un contacteur de petite taille (en profondeur) par une nervure 25 engagée dans le cran haut 39 ; sur la figure 5 le montage d'un contacteur de grande taille (en profondeur), la pièce 30 étant respectivement en position avancée et reculée. Dans ces deux cas, le contacteur coopère par une nervure 25 avec le cran haut 39 de la pièce 30. Sur la figure 6 est représenté le montage d'un contacteur de grande taille (en hauteur), c'est-à-dire dont la partie avant est plus haute que la partie arrière, sa nervure 25 est alors située plus bas par rapport à sa face haute 26 et est engagée dans le cran bas 40 de la pièce 30.We see on the figure 4 mounting a small contactor (in depth) by a rib 25 engaged in the high notch 39; on the figure 5 the mounting of a large contactor (in depth), the part 30 being respectively in the advanced and retracted position. In these two cases, the contactor cooperates with a rib 25 with the notch high 39 of the piece 30. On the figure 6 is shown the assembly of a contactor large (height), that is to say whose front portion is higher than the rear portion, its rib 25 is then lower relative to its upper face 26 and is engaged in the low notch 40 of the workpiece 30.

L'invention vise aussi la possibilité de réglage de la position du contacteur relativement au disjoncteur par des crans ou parties réglables associés à la pièce 30 du côté du disjoncteur. D'autre part, les formes mâles ou femelles qui ont été décrites peuvent bien entendu être inversées. Selon les cas, l'adaptation peut être opérée sur la position de la face arrière 21 du contacteur par rapport à celle de la face arrière 16 du disjoncteur, ou de la face avant 22 du contacteur par rapport à la face avant 17 du disjoncteur. Le disjoncteur décrit peut être remplacé par un appareil porte-fusible ou autre appareil de protection analogue.The invention also relates to the possibility of adjusting the position of the contactor relative to the circuit breaker by notches or adjustable parts associated with the part 30 on the side of the circuit breaker. On the other hand, the male or female forms that have been described can of course be reversed. Depending on the case, the adaptation can be made on the position of the rear face 21 of the contactor relative to that of the rear face 16 of the circuit breaker, or the front face 22 of the contactor relative to the front face 17 of the circuit breaker. The described circuit breaker may be replaced by a fuse holder or other similar protective device.
