La première tige 72 est configurée pour s'insérer dans le premier orifice 47 et dans le premier trou 57 de chaque contact auxiliaire 5. La deuxième tige 74 est configurée pour s'insérer dans le deuxième orifice 49 et dans le deuxième trou 59 de chaque contact auxiliaire 5 qui est logé dans le support 40. Les tiges 72, 74 solidarisent alors les contacts auxiliaires 5 au support 40 en les immobilisant relativement au support 40.The first rod 72 and the second rod 74 are intended to attach the auxiliary contacts 5 to the support 40. The first rod 72 is configured to fit into the first orifice 47 and into the first hole 57 of each auxiliary contact 5. The second rod 74 is configured to fit in the second orifice 49 and in the second hole 59 of each auxiliary contact 5 which is housed in the support 40. The rods 72, 74 then secure the auxiliary contacts 5 to the support 40 by immobilizing them relatively to support 40.

La tête 71 de l'attache 70 est configurée pour coopérer mécaniquement avec un organe de maintien 80, à la fois pour guider et orienter la tête 71 relativement à la deuxième platine 21 et pour solidariser la tête 71 à la deuxième platine 21. Cet organe de maintien 80 sera décrit ci-après.The head 71 of the fastener 70 is configured to cooperate mechanically with a holding member 80, both for guiding and orienting the head 71 relative to the second plate 21 and for securing the head 71 to the second plate 21. holding 80 will be described hereinafter.

La queue 73 de l'attache est destinée à s'insérer dans des orifices 13, 15 de l'embase 2, pour immobiliser la queue 73 de l'attache 70 relativement à la platine 20 de l'embase 2.The tail 73 of the fastener is intended to fit into the orifices 13, 15 of the base 2, to immobilize the tail 73 of the fastener 70 relative to the plate 20 of the base 2.

L'embase 2 comprend une entaille 11, située sur la face interne de la première platine 20, pour guider la première extrémité 41 du support relativement à l'embase 2, avant de retenir la queue 73 relativement à l'embase 2.The base 2 comprises a notch 11, located on the inner face of the first plate 20, to guide the first end 41 of the support relative to the base 2, before retaining the tail 73 relative to the base 2.

L'entaille 11 est située sur la face interne de la première platine 20. Elle s'étend depuis son entrée 11a qui débouche sur l'extérieur de la première platine 20, jusqu'à une extrémité opposée 11b qui est de forme circulaire et qui comprend le premier orifice 13 en son centre.The notch 11 is located on the inner face of the first plate 20. It extends from its inlet 11a which opens on the outside of the first plate 20, to an opposite end 11b which is circular in shape and which includes the first port 13 at its center.

L'entaille 11 a une forme sensiblement rectiligne entre son entrée 11a et son extrémité 11b et elle est inclinée par rapport à la direction transversale X-X. L'entaille a deux flancs latéraux opposés 16, 17 qui sont chacun sensiblement plans et qui s'étendent chacun depuis l'entrée 11a jusqu'à l'extrémité 11b.The cut 11 has a substantially rectilinear shape between its inlet 11a and its end 11b and is inclined relative to the transverse direction XX. The notch has two opposite lateral flanks 16, 17 which are each substantially planar and which each extend from the inlet 11a to the end 11b.

L'entaille 11 est destinée à recevoir la protubérance 44 de la première extrémité 41 du support 40, en guidant le déplacement de la protubérance 44 grâce à une coopération de forme avec l'entaille 11. Les flancs latéraux 16, 17 de l'entaille ont notamment une forme complémentaire de celle des bords 46 de la protubérance, pour pouvoir la faire coulisser dans l'entaille 11. L'entaille 11 est apte à guider la protubérance en translation rectiligne entre son entrée 11a et son extrémité 11b.The notch 11 is intended to receive the protuberance 44 of the first end 41 of the support 40, guiding the displacement of the protuberance 44 through a form cooperation with the notch 11. The lateral flanks 16, 17 of the notch have in particular a shape complementary to that of the edges 46 of the protrusion, to be able to slide in the notch 11. The notch 11 is adapted to guide the protuberance in rectilinear translation between its inlet 11a and its end 11b.

L'entaille 11 et la protubérance 44 assurent donc le rôle d'un moyen de guidage de la première extrémité 41 du support relativement à la première platine 20. Ils sont configurés pour guider la première extrémité 41 du support depuis sa position de séparation jusqu'à sa position de raccordement.The notch 11 and the protuberance 44 therefore act as a means of guiding the first end 41 of the support relative to the first plate 20. They are configured to guide the first end 41 of the support from its separation position to the at its connection position.

Après que la protubérance 44 soit logée dans l'extrémité 11b de l'entaille 11 et que le support 40 ait pivoté autour de la première tige 72, la première tige 72 est configurée pour traverser la protubérance 44 en s'insérant dans le premier orifice 13. De manière simultanée à l'insertion de la première tige 72 dans le premier orifice 13, la deuxième tige 74 est configurée pour s'insérer au niveau de la première extrémité 41 du support dans le deuxième orifice 15.After the protuberance 44 is received in the end 11b of the notch 11 and the support 40 has pivoted around the first rod 72, the first rod 72 is configured to pass through the protuberance 44 by fitting into the first orifice 13. Simultaneously with the insertion of the first rod 72 into the first port 13, the second rod 74 is configured to insert at the first end 41 of the support into the second port 15.

Le premier orifice 13 et le deuxième orifice 15 sont des trous borgnes ménagés sur la face interne de la première platine 20. Ils sont destinés à retenir la queue 73 de l'attache 70 relativement à l'embase 2. Ils forment alors conjointement un moyen de retenue de la première extrémité 41 du support relativement à l'embase 2.The first orifice 13 and the second orifice 15 are blind holes formed on the internal face of the first plate 20. They are intended to retain the tail 73 of the fastener 70 relative to the base 2. They then form together a means retaining the first end 41 of the support relative to the base 2.

La deuxième platine 21 comprend une première rainure 81 dite rainure supérieure et une deuxième rainure 83 dite rainure inférieure.The second plate 21 comprises a first groove 81 called upper groove and a second groove 83 called lower groove.

La première rainure 81 s'étend sensiblement selon la direction transversale X-X de l'embase en traversant la deuxième platine 21 selon cette direction. La première rainure 81 est sensiblement en vis-à-vis du premier orifice 13.The first groove 81 extends substantially in the transverse direction X-X of the base through the second plate 21 in this direction. The first groove 81 is substantially vis-à-vis the first orifice 13.

La deuxième rainure 83 s'étend sensiblement selon la direction transversale X-X de l'embase en traversant la deuxième platine 21 selon cette direction. La deuxième rainure 83 est située sensiblement en vis-à-vis du deuxième orifice 15.The second groove 83 extends substantially in the transverse direction XX of the base through the second plate 21 in this direction. The second groove 83 is located substantially vis-à-vis the second orifice 15.

La deuxième platine 21 comprend un rebord supérieur 82 au-dessus de la première rainure 81, un rebord intermédiaire 84 entre les rainures 81, 83 et un rebord inférieur 86 sous la deuxième rainure 83.The second plate 21 comprises an upper flange 82 above the first groove 81, an intermediate flange 84 between the grooves 81, 83 and a lower flange 86 under the second groove 83.

Le rebord intermédiaire 84 est délimité au niveau de la première rainure 81 par une première surface de contact Si avec la première tige 72. Il est délimité au niveau de la deuxième rainure 83 par une deuxième surface de contact S2 avec la deuxième tige 74.The intermediate flange 84 is delimited at the level of the first groove 81 by a first contact surface Si with the first rod 72. It is delimited at the level of the second groove 83 by a second contact surface S 2 with the second rod 74.

La première rainure 81 est destinée à recevoir la première tige 72 une fois que la protubérance 44 est engagée dans l'extrémité 11b de l'entaille 11, la première tige 72 prenant appui sur le rebord intermédiaire 84.The first groove 81 is intended to receive the first rod 72 once the protrusion 44 is engaged in the end 11b of the notch 11, the first rod 72 bearing on the intermediate flange 84.

La première rainure 81 est destinée à faire pivoter la première tige 72 autour de son axe longitudinal. Le pivotement de la première tige 72 fait pivoter le support 40 autour de cet axe et permet d'introduire la deuxième tige 74 dans la deuxième rainure 83.The first groove 81 is intended to rotate the first rod 72 about its longitudinal axis. The pivoting of the first rod 72 rotates the support 40 around this axis and makes it possible to introduce the second rod 74 into the second groove 83.

La deuxième rainure 83 est destinée à recevoir la deuxième tige 74 lorsque le support 40 a pivoté autour de la première tige 72, la deuxième tige 74 prenant appui sur le rebord intermédiaire 84. La tête 71 de l'attache est immobilisée dans toutes les directions sauf éventuellement en translation selon la direction transversale X-X, lorsque la première tige 72 est dans la première rainure 81 et que la deuxième tige 74 est dans la deuxième rainure 83.The second groove 83 is intended to receive the second rod 74 when the support 40 has pivoted around the first rod 72, the second rod 74 bearing on the intermediate flange 84. The head 71 of the fastener is immobilized in all directions except possibly in translation in the transverse direction XX, when the first rod 72 is in the first groove 81 and the second rod 74 is in the second groove 83.

La première rainure 81, le rebord intermédiaire 84 et la deuxième rainure 83 jouent donc à la fois le rôle de moyen de guidage de la deuxième extrémité du support 43 relativement à la deuxième platine 21, et le rôle de moyen de retenue de la deuxième extrémité du support 43 relativement à la deuxième platine 21. Ils forment conjointement l'organe de maintien 80.The first groove 81, the intermediate flange 84 and the second groove 83 thus play both the role of guiding means of the second end of the support 43 relative to the second plate 21, and the role of retaining means of the second end. of the support 43 relative to the second plate 21. They form together the holding member 80.

La tête 71 de l'attache est configurée pour être déplacée en direction de la première extrémité 41 du support, lorsque le support 40 est en position de raccordement et que l'organe de maintien 80 retient la tête 71 de l'attache.The head 71 of the fastener is configured to be moved towards the first end 41 of the support, when the support 40 is in the connection position and the holding member 80 retains the head 71 of the fastener.

Pour cela l'organe de maintien 80 comporte par exemple une troisième rainure 85 qui est perpendiculaire aux première et deuxième rainures 81, 83, et dans laquelle la tête 71 vient s'insérer lorsque le support 40 est en position de raccordement. L'attache 70 est notamment destinée à venir en contact de l'organe de maintien sur trois côtés du rebord intermédiaire 84.For this, the holding member 80 comprises for example a third groove 85 which is perpendicular to the first and second grooves 81, 83, and in which the head 71 is inserted when the support 40 is in the connection position. The fastener 70 is in particular intended to come into contact with the holding member on three sides of the intermediate flange 84.

Lorsque la tête 71 de l'attache se déplace selon la direction transversale X-X jusqu'à venir en contact mécanique du rebord intermédiaire 84, la première tige 72 s'insère dans le premier orifice 13 et la deuxième tige 74 s'insère dans le deuxième orifice 15.When the head 71 of the fastener moves in the transverse direction XX until it comes into mechanical contact with the intermediate flange 84, the first rod 72 is inserted in the first orifice 13 and the second rod 74 is inserted in the second orifice 15.

L'appareil 1 comprend un cache 78 configuré pour engager une extrémité de l'arbre auxiliaire 6 à travers la première platine 20, et pour recouvrir la tête 71 de l'attache. Le cache 78 comprend à sa surface des informations relatives à la position des contacts électriques 5 relativement au support 40, pour faciliter l'intervention d'un opérateur sur l'appareil 1.The apparatus 1 comprises a cover 78 configured to engage one end of the auxiliary shaft 6 through the first plate 20, and to cover the head 71 of the clip. The cover 78 comprises on its surface information relating to the position of the electrical contacts 5 relative to the support 40, to facilitate the intervention of an operator on the device 1.

L'appareil 1 comporte également un flasque 79 configuré pour recouvrir le cache 78. Le flasque 79 est configuré pour être vissé sur la première platine 20. Il est transparent en formant une fenêtre permettant à un opérateur de lire les informations sur le cache 78.The apparatus 1 also comprises a flange 79 configured to cover the cover 78. The flange 79 is configured to be screwed onto the first plate 20. It is transparent by forming a window allowing an operator to read the information on the cache 78.

Le cache 78 et le flasque 79 empêchent le retrait accidentel de l'attache 70 de l'embase 2. Ils jouent le rôle de moyen de retenue de la tête 71 de l'attache selon la direction transversale X-X. En effet, il faut préalablement enlever le cache 78 et le flasque 79 avant de pouvoir retirer l'attache 70 et le reste du bloc de contacts électriques 4.The cover 78 and the flange 79 prevent the accidental removal of the fastener 70 of the base 2. They act as a means of retaining the head 71 of the fastener in the transverse direction X-X. Indeed, it is necessary to first remove the cover 78 and the flange 79 before being able to remove the fastener 70 and the rest of the block of electrical contacts 4.

L'attache 70, le cache 78 et le flasque 79 forment conjointement le système d'attache 7 du bloc de contacts auxiliaires 4 à l'embase 2.The fastener 70, the cover 78 and the flange 79 together form the attachment system 7 of the auxiliary contact block 4 to the base 2.

Le procédé de raccordement électrique du bloc de contacts électriques auxiliaires 4 au bloc de contacts principaux 3 est maintenant décrit ci-dessous.The method of electrically connecting the auxiliary electrical contact block 4 to the main contact block 3 is now described below.

Tout d'abord, en référence à la figure 3, les contacts électriques auxiliaires 5 sont insérés dans les alvéoles 45 du support. La première tige 72 et la deuxième tige 74 sont insérées à travers le support 40 et les contacts électriques auxiliaires 5. Les contacts auxiliaires 5 sont alors attachés au support 40.First, with reference to the figure 3 , the auxiliary electrical contacts 5 are inserted into the cells 45 of the support. The first rod 72 and the second rod 74 are inserted through the support 40 and the auxiliary electrical contacts 5. The auxiliary contacts 5 are then attached to the support 40.

En référence à la figure 4, la protubérance 44 est guidée dans l'entaille 11 de la première platine 20, depuis la position de séparation du support 40 jusqu'à sa position de raccordement. Simultanément, la première tige 72 est insérée dans la première rainure 81 de la deuxième platine 21. A la figure 4, le support 40 est alors dans une position intermédiaire dans laquelle la première tige 72 est engagée dans la première rainure 81 et la deuxième tige 84 n'est pas encore engagée dans la deuxième rainure 83.With reference to the figure 4 , the protrusion 44 is guided in the notch 11 of the first plate 20, from the separation position of the support 40 to its position connection. Simultaneously, the first rod 72 is inserted into the first groove 81 of the second plate 21. figure 4 the support 40 is then in an intermediate position in which the first rod 72 is engaged in the first groove 81 and the second rod 84 is not yet engaged in the second groove 83.

En référence à la figure 5, la première tige 72 pivote autour de son axe longitudinal. Le support 40 étant solidaire en rotation de la première tige 72, il pivote autour de son axe longitudinal Y-Y relativement à l'embase 2. La première tige 72 pivote jusqu'à ce que la deuxième tige 74 s'insère dans la deuxième rainure 83 de la deuxième platine 21. La tête 71 est alors retenue par rapport à la deuxième platine 21.With reference to the figure 5 , the first rod 72 pivots about its longitudinal axis. The support 40 being integral in rotation with the first rod 72, it pivots about its longitudinal axis YY relative to the base 2. The first rod 72 pivots until the second rod 74 is inserted into the second groove 83 of the second plate 21. The head 71 is then retained relative to the second plate 21.

Lorsque la première tige 72 est retenue dans la première rainure 81 et la deuxième tige 74 dans la deuxième rainure 83, les contacts électriques auxiliaires 5 sont à proximité de l'arbre auxiliaire 6 et ils peuvent se fermer lorsqu'ils sont actionnés par les cames 60 de l'arbre auxiliaire 6.When the first rod 72 is retained in the first groove 81 and the second rod 74 in the second groove 83, the auxiliary electrical contacts 5 are close to the auxiliary shaft 6 and they can close when they are actuated by the cams 60 of the auxiliary shaft 6.

En référence à la figure 6, la tête 71 de l'attache est poussée selon la direction transversale X-X en direction de la première platine 20 jusqu'à venir en contact mécanique du rebord intermédiaire 84. La queue 73 de l'attache s'insère dans le premier orifice 13 et dans le deuxième orifice 15, lorsque l'attache 70 est poussée. Le support 40 est alors attaché à l'embase 2, en étant rigidement solidaire de l'embase 2. Le support 40 est dans la position de raccordement.With reference to the figure 6 the head 71 of the fastener is pushed in the transverse direction XX in the direction of the first plate 20 until it comes into mechanical contact with the intermediate flange 84. The tail 73 of the fastener is inserted into the first orifice 13 and in the second orifice 15, when the fastener 70 is pushed. The support 40 is then attached to the base 2, being rigidly secured to the base 2. The support 40 is in the connection position.

En référence à la figure 6 et à la figure 1, le cache 78 et le flasque 79 sont ensuite assemblés à la deuxième platine 21, ce qui limite encore les risques de retrait de l'attache 70.With reference to the figure 6 and at the figure 1 , the cover 78 and the flange 79 are then assembled to the second plate 21, which further limits the risk of removal of the fastener 70.

Le procédé de séparation du bloc de contacts électriques auxiliaires 4 de l'embase 2 est maintenant décrit ci-après.The method of separating the block of auxiliary electrical contacts 4 from the base 2 is now described below.

Tout d'abord, le cache 78 et le flasque 79 sont retirés de l'embase 2, ce qui permet d'extraire la tête 71 de l'attache selon la direction transversale X-X à l'opposé de la première platine 20. La queue 73 de l'attache est alors retirée du premier orifice 13 et du deuxième orifice 15. L'attache 70 est alors éventuellement désengagée de certains des contacts auxiliaires 5.First, the cover 78 and the flange 79 are removed from the base 2, which allows to extract the head 71 of the fastener in the transverse direction XX opposite the first plate 20. The tail 73 of the fastener is then removed from the first orifice 13 and the second orifice 15. The fastener 70 is then optionally disengaged from some of the auxiliary contacts 5.

La première tige 72 pivote autour de son axe longitudinal, ce qui permet de faire sortir la deuxième tige 74 de la deuxième rainure 83.The first rod 72 pivots about its longitudinal axis, which makes it possible to release the second rod 74 from the second groove 83.

Le support 40 est ensuite guidé dans l'entaille 11 depuis l'extrémité 11b de l'entaille jusqu'à l'entrée 11a de l'entaille, un opérateur tenant l'attache 70. Le bloc de contacts auxiliaires 4 est ensuite éloigné de l'embase 2.The support 40 is then guided in the notch 11 from the end 11b of the notch to the entrance 11a of the notch, an operator holding the fastener 70. The auxiliary contact block 4 is then moved away from the base 2.

La première tige 72 et la deuxième tige 74 sont retirées du premier orifice 47 et du deuxième orifice 49 du support. Une fois que l'attache 70 est retirée du support 40, les contacts auxiliaires 5 peuvent être extraits de leur logement. Des contacts auxiliaires 5 peuvent ensuite être retirés, ajoutés ou déplacés dans le support 40. Des contacts auxiliaires 5 peuvent également être remplacés.The first rod 72 and the second rod 74 are withdrawn from the first orifice 47 and the second orifice 49 of the support. Once the clip 70 is removed from the support 40, the auxiliary contacts 5 can be extracted from their housing. Auxiliary contacts 5 can then be removed, added or moved into the holder 40. Auxiliary contacts 5 can also be replaced.

Bien entendu, diverses modifications peuvent être apportées par l'homme du métier à l'invention qui vient d'être décrite sans sortir du cadre de l'exposé de l'invention.Of course, various modifications may be made by those skilled in the art to the invention which has just been described without departing from the scope of the disclosure of the invention.

La forme de l'attache 70 peut varier. Par exemple, la tête 71 de l'attache peut avoir une forme ondulée. Les tiges 72 de l'attache 74 peuvent ne pas être parallèles entre elles. Par ailleurs, les tiges 72 74 peuvent avoir des longueurs différents l'une de l'autre ou des diamètres différents l'une de l'autre.The shape of the fastener 70 may vary. For example, the head 71 of the clip may have a wavy shape. The rods 72 of the fastener 74 may not be parallel to each other. Moreover, the rods 72 may have lengths that are different from one another or diameters that are different from one another.

Selon un mode de réalisation (non représenté), la deuxième tige 74 est plus courte que la première tige 72 et l'attache 70 n'est en contact mécanique de la première platine 20 que par le premier orifice 13.According to one embodiment (not shown), the second rod 74 is shorter than the first rod 72 and the fastener 70 is in mechanical contact with the first plate 20 only by the first orifice 13.

L'entaille 11 peut également présenter une forme différente. Il peut s'agir par exemple d'une entaille 11 curviligne au lieu d'une entaille rectiligne.The notch 11 may also have a different shape. It may be for example a curvilinear cut 11 instead of a straight cut.

Suivant la forme de la première extrémité 41 du support, la première platine 20 peut même comprendre plusieurs entailles.Depending on the shape of the first end 41 of the support, the first plate 20 may even include several notches.

L'organe de maintien 80 peut également présenter une forme différente. La forme de la tête 71 de l'attache est alors adaptée à la forme de l'organe de maintien 80. L'organe de maintien peut être par exemple un élément rapporté sur la deuxième platine 21, tel qu'une agrafe.The holding member 80 may also have a different shape. The shape of the head 71 of the fastener is then adapted to the shape of the holding member 80. The holding member may be for example an element attached to the second plate 21, such as a clip.

L'appareil 1 peut être dépourvu de cache 78 et/ou de flasque 79.The apparatus 1 may be devoid of cover 78 and / or flange 79.

L'arbre auxiliaire 6 et/ou l'arbre principal peuvent être démontable par rapport à l'embase 2. Ils peuvent être démontables l'un par rapport à l'autre ou non.The auxiliary shaft 6 and / or the main shaft can be dismountable relative to the base 2. They can be disassembled relative to each other or not.
