These actuators are distributed lastly according to the dedicated locations available in the architecture of the device. This architecture of the device is not designed in compliance with the two concepts mentioned above respectively simplicity of installation and ease of access.

On connaît également une solution qui consiste à maintenir les auxiliaires par leur partie haute au moyen d'une bride.A solution is also known which consists in keeping the auxiliaries at their upper part by means of a flange.

Sur les figures 1,4,6,7,8 et 9, on voit un disjoncteur électrique D comportant un dispositif de fixation d'actionneurs sur le mécanisme de disjoncteur selon l'invention. Ce dispositif de fixation F est destiné à permettre la mise en place des actionneurs 1, leur fixation et leur raccordement audit mécanisme M, lesdits actionneurs 1, dont l'un est représenté séparément sur la figure 3, pouvant agir sur un verrouillage en permettant de l'effacer, ce qui permet au mécanisme de réaliser l'opération d'ouverture ou de fermeture.On the figures 1 , 4 , 6 , 7 , 8 and 9 , we see an electric circuit breaker D having an actuator fixing device on the circuit breaker mechanism according to the invention. This fixing device F is intended to allow the introduction of the actuators 1, their attachment and their connection to said mechanism M, said actuators 1, one of which is shown separately on the figure 3 , able to act on a lock by allowing to delete it, which allows the mechanism to perform the opening or closing operation.

Ce dispositif de fixation selon l'invention comporte une plaque-support 2, illustrée séparément sur la figure 2, ladite plaque 2 étant destinée à être fixée au bâti ou châssis 3 de l'appareil, par tout moyen approprié, et étant destinée à recevoir un ou plusieurs actionneurs 1, ces actionneurs étant au nombre de trois dans cette réalisation particulière et prenant la forme chacun d'une bobine.This fixing device according to the invention comprises a support plate 2, illustrated separately on the figure 2 , said plate 2 being intended to be fixed to the frame or frame 3 of the apparatus, by any appropriate means, and being intended to receive one or more actuators 1, these actuators being three in this particular embodiment and taking the form each of a coil.

Cette plaque-support 2 comporte donc trois emplacements 4 pour respectivement trois actionneurs, chaque emplacement comportant un orifice 5 destiné à permettre le passage d'une tige 6 destinée à établir la liaison mécanique entre le mécanisme M de l'appareil et chacun des actionneurs 1. Chaque emplacement 4 comporte également deux orifices 7 destinés à permettre le passage d'un élément en forme de crochet 8 solidaire du socle de l'actionneur 1. Cet orifice comporte une première partie élargie 10 suivie d'une partie rétrécie 11, la partie élargie 10 étant orientée du côté intérieur de la plaque 2, tandis que la partie rétrécie 11 de l'orifice est orientée vers l'extérieur de la plaque 2.This support plate 2 thus comprises three locations 4 for respectively three actuators, each location having an orifice 5 intended to allow the passage of a rod 6 intended to establish the mechanical connection between the mechanism M of the device and each of the actuators 1 Each slot 4 also comprises two orifices 7 intended to allow the passage of a hook-shaped element 8 integral with the base of the actuator 1. This orifice comprises a first enlarged part 10 followed by a narrowed part 11, the part 10 being oriented on the inner side of the plate 2, while the narrowed portion 11 of the orifice is oriented towards the outside of the plate 2.

On notera, comme ceci est particulièrement visible sur la figure 2, que sur le côté gauche de la plaque comportant deux emplacements pour respectivement deux actionneurs, l'un des orifices 7 situé sensiblement au centre, est destiné à recevoir deux éléments en forme de crochet appartenant respectivement à deux actionneurs. L'un des deux éléments en forme de crochet situé du côté de la tirette appartenant à l'un des actionneurs situé du côté de la tirette, coopérant alors avec le bord de la plaque 2 qui présente une forme correspondant à celle de la moitié d'un orifice 7.Note, as this is particularly visible on the figure 2 , that on the left side of the plate having two locations for respectively two actuators, one of the orifices 7 located substantially in the center, is intended to receive two hook-shaped elements respectively belonging to two actuators. One of the two hook-shaped elements located on the side of the pull tab belonging to one of the actuators located on the side of the pull tab, then cooperating with the edge of the plate 2 which has a shape corresponding to that of the half of an orifice 7.

Le dispositif de fixation F selon l'invention comporte également une tirette 12 montée coulissante par rapport à la plaque support 2 par l'intermédiaire d'une rainure 13 prévue dans la partie centrale de la tirette coopérant avec deux plots 14 solidaires de la plaque-support 2. Cette tirette 12 est apte à être entraînée en coulissement par l'intermédiaire d'une partie de préhension 15 formée à l'une 12a des extrémités de ladite tirette, tandis qu'à son extrémité opposée 12b, ladite tirette comporte une patte 16 de forme sensiblement rectangulaire. Cette partie rectangulaire comporte trois portions 17,18,19 s'étendant en saillie à partir des bords longitudinaux 12c de cette partie rectangulaire, ces portions présentant une section triangulaire dans un plan sensiblement parallèle à celui de la plaque-support 2. Ces éléments 17,18,19 en saillie à partir des bords 12c de la tirette sont destinés à coopérer chacun avec l'une 20 des faces appartenant à un actionneur 1 comme ceci sera expliqué dans ce qui suit.The fastening device F according to the invention also comprises a pull tab 12 slidably mounted relative to the support plate 2 by means of a groove 13 provided in the central part of the pull tab cooperating with two studs 14 integral with the plate. support 2. This pull tab 12 is able to be slidably driven through a gripping portion 15 formed at one end 12a of said pull tab, while at its opposite end 12b, said pull tab comprises a tab 16 of substantially rectangular. This rectangular portion comprises three portions 17, 18, 19 extending projecting from the longitudinal edges 12c of this rectangular part, these portions having a triangular section in a plane substantially parallel to that of the support plate 2. These elements 17 18,19 protruding from the edges 12c of the pull tab are intended to cooperate each with one of 20 faces belonging to an actuator 1 as will be explained in the following.

Le fonctionnement du dispositif selon l'invention va être décrit dans ce qui suit en référence aux figures.The operation of the device according to the invention will be described in the following with reference to the figures.

Sur la figure 1, les actionneurs 1 ne sont pas encore montés sur la plaque-support 2 et le dispositif de fixation F est en position déverrouillé. Dans cette position, la position de l'élément de préhension 15 de la tirette empêche la fermeture du plastron de commande P représenté sur la figure 9.On the figure 1 , the actuators 1 are not yet mounted on the support plate 2 and the fixing device F is in the unlocked position. In this position, the position of the gripping element 15 of the pull tab prevents the closing of the control panel P shown in FIG. figure 9 .

Sur la figure 4, un actionneur 1 est présenté sur la plaque afin d'y être fixé. Pour se faire, la tige de commande 6 de l'actionneur 1 est introduite à travers une ouverture 5 de la plaque 2 de manière à être reliée mécaniquement au mécanisme M du disjoncteur D. Puis, le crochet 8 de l'actionneur est introduit dans l'autre orifice 7 de la plaque par sa partie élargie 10. Puis, l'actionneur 1 est déplacé suivant une direction sensiblement perpendiculaire à l'axe de déplacement de la tirette, tel que représenté sur la figure 5, de manière que son crochet passe de la partie élargie 10 de l'orifice à sa partie rétrécie 11, position dans laquelle l'actionneur est maintenu sur la plaque et ne peut plus se déplacer par rapport à cette plaque que suivant la direction précédemment mentionnée en direction de la tirette, cette position étant illustrée sur la figure 6.On the figure 4 , an actuator 1 is shown on the plate to be attached. To do this, the control rod 6 of the actuator 1 is introduced through an opening 5 of the plate 2 so as to be mechanically connected to the mechanism M of the circuit breaker D. Then, the hook 8 of the actuator is introduced into the other orifice 7 of the plate by its enlarged portion 10. Then, the actuator 1 is moved in a direction substantially perpendicular to the axis of movement of the pull tab, as shown in FIG. figure 5 , so that its hook passes from the widened portion 10 of the orifice to its narrowed portion 11, position in which the actuator is held on the plate and can not move relative to this plate as in the direction previously mentioned in the direction of the zipper, this position being illustrated on the figure 6 .

L'actionneur étant monté fixement sur la plaque-support, le dispositif de fixation peut être amené dans la position verrouillée par déplacement de la tirette 12 jusqu'à ce que l'un de ces éléments en saillie 17 se trouve en regard de la face 20 du socle de l'actionneur se trouvant en regard de ladite tirette, position dans laquelle l'actionneur est maintenu immobile par rapport à la plaque 2, son déplacement selon la direction précédemment mentionnée étant empêché, tel qu'illustré sur la figure 7.The actuator being fixedly mounted on the support plate, the fixing device can be brought into the locked position by moving the pull tab 12 until one of these projecting elements 17 is opposite the face. 20 of the base of the actuator located opposite said pull tab, position in which the actuator is held stationary relative to the plate 2, its displacement in the previously mentioned direction being prevented, as illustrated in FIG. figure 7 .

Sur la figure 8, trois actionneurs 1,21,22 ont été montés sur la plaque-support 2 de la manière décrite précédemment sur respectivement trois emplacements, le dispositif de fixation selon l'invention étant dans la position déverrouillée. Sur la figure 9, le dispositif est en position verrouillée, la tirette 12 ayant été déplacée en direction de l'intérieur de la plaque-support 2, les éléments en saillie 17,18,19 de la tirette 12 étant en appui contre les faces correspondantes 20,23,24 des actionneurs 1,21,22 de manière à empêcher leur déplacement et maintenir ainsi lesdits actionneurs fixement sur la plaque-support 2.On the figure 8 , three actuators 1,21,22 were mounted on the support plate 2 as previously described on three locations respectively, the fastening device according to the invention being in the unlocked position. On the figure 9 , the device is in the locked position, the pull tab 12 having been moved towards the interior of the support plate 2, the projecting elements 17,18,19 of the pull tab 12 being in abutment against the corresponding faces 20,23,24 of the actuators 1,21,22 so as to prevent their movement and thus maintain said actuators fixed on the support plate 2.

On notera qu'un autre mode de réalisation du système de maintien en position des actionneurs pourrait consister en une glissière fermée à l'une de ses extrémités prévue sur la plaque et coopérant avec un élément coulissant solidaire du socle de l'actionneur, ou bien inversement une glissière fermée prévue sur le socle de l'actionneur coopérant avec un élément coulissant prévu sur la plaque.It will be noted that another embodiment of the position holding system of the actuators could consist of a slide closed at one of its ends provided on the plate and cooperating with a sliding element integral with the base of the actuator, or conversely a closed slide provided on the base of the actuator cooperating with a sliding element provided on the plate.

On a donc réalisé grâce à l'invention, un dispositif de fixation permettant d'améliorer sous l'angle utilisateur, la tenue des actionneurs permettant la commande des disjoncteurs, et plus particulièrement leur disposition et leur mode d'assemblage et de fixation.Thus, thanks to the invention, a fastening device has been made that makes it possible to improve, under the user angle, the behavior of the actuators enabling the control of the circuit breakers, and more particularly their arrangement and their method of assembly and fixing.

Le dispositif selon l'invention permet de maintenir parfaitement en position des éléments tels que par exemple des auxiliaires à manque de tension, rapidement, sans outil, et en utilisant un nombre limité de pièces, lesquelles étant imperdables, l'utilisation de moyens de fixation selon l'invention étant rendue possible grâce au regroupement sur une seule platine de ces actionneurs.The device according to the invention makes it possible to perfectly maintain in position elements such as, for example, auxiliaries without voltage, quickly, without tools, and by using a limited number of parts, which are captive, the use of fixing means according to the invention is made possible by the grouping on a single plate of these actuators.

On réalise ainsi un assemblage de blocs autonomes avec une possibilité de différenciation retardée pour l'installateur. Quelles que soient les raisons (fin de l'utilisation de l'auxiliaire, maintenance, adaptation en tension, ajout de fonctionnalités....), le client peut facilement changer ses auxiliaires avec une ergonomie enfin adaptée dans un compartiment spécifiquement créé pour lui. Ceci est réalisé également de manière sécuritaire, car si le montage n'est pas réalisé correctement, le plastron de commande ne peut pas être remis en place et la commande n'est pas utilisable.An assembly of autonomous blocks is thus realized with a possibility of delayed differentiation for the installer. Whatever the reasons (end of the use of the auxiliary, maintenance, adaptation in tension, addition of functionalities ....), the customer can easily change his auxiliaries with ergonomics finally adapted in a compartment specifically created for him . This is also done safely, because if the assembly is not done correctly, the front plate can not be put back in place and the command is not usable.

Ce dispositif selon l'invention maintient les auxiliaires par leur partie basse. Ceci est avantageux par le fait que la zone importante pour le respect des chaines de côtes se situe sur le bas, où agit la tirette.This device according to the invention maintains the auxiliaries by their lower part. This is advantageous in that the important area for the respect of the chains of ribs is on the bottom, where acts the zipper.

Une autre solution moins intéressante aurait pu être envisagée, laquelle ayant été de prévoir un positionnement des actionneurs sur la plaque-support par l'intermédiaire d'éléments de positionnement complémentaires prévus en partie sur le socle de l'actionneur et en partie sur la plaque, laquelle plaque-support étant ensuite clipsée sur le châssis du mécanisme du disjoncteur.Another less interesting solution could have been envisaged, which had been to provide a positioning of the actuators on the support plate by means of complementary positioning elements provided partly on the base of the actuator and partly on the plate. , which support plate is then clipped on the chassis of the circuit breaker mechanism.

Cette solution est cependant moins avantageuse par le fait notamment qu'elle ne permet pas une coopération entre le dispositif de verrouillage et le plastron de commande du mécanisme du disjoncteur.This solution is however less advantageous in particular because it does not allow cooperation between the locking device and the control plate of the circuit breaker mechanism.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et illustrés qui n'ont été donnés qu'à titre d'exemples.Of course, the invention is not limited to the described and illustrated embodiments which have been given only as examples.
