A cette fin, le dispositif de l'invention, par ailleurs conforme à la définition générique qu'en donne le préambule ci-dessus, est essentiellement caractérisé en ce que 1 ' actionneur comprend une manette montée pivotante sur le boîtier et dotée d'un moyeu dont une partie est visible de l'extérieur du boîtier, un excentrique solidaire de la manette, et une bielle mue par l'excentrique, en ce que le mécanisme d'armement comprend, outre 1 ' actionneur, un coulisseau d'entraînement portant le contact mobile et sollicité suivant une première direction par une première force élastique, en ce que la manette, déplacée en pivotement depuis une position de repos vers une position d'enclenchement et agissant par l'intermédiaire de la bielle placée dans une configuration engagée, déplace sélectivement le coulisseau en coulissement par rapport au boîtier depuis une position inactive jusque dans une position active suivant une seconde direction inverse de la première direction et le long d'un premier axe passant entre les deux contacts fixes, le coulisseau atteignant sa position active dans la position d'enclenchement de la manette, et en ce que la partie visible du moyeu de la manette porte un premier voyant d'état, lui-même visible de l'extérieur du boîtier dans la position de repos de la manette et masqué par le boîtier dans toute position de la manette pour laquelle, en configuration engagée de la bielle, le coulisseau adopte une position comprise entre sa position active et une position intermédiaire entre ses positions active et inactive.To this end, the device of the invention, moreover conforms to the generic definition given in the preamble above, is essentially characterized in that the actuator comprises a lever pivotally mounted on the housing and provided with a hub, part of which is visible from the outside of the housing, an eccentric integral with the lever, and a connecting rod moved by the eccentric, in that the arming mechanism comprises, in addition to the actuator, a driving slide bearing the movable and biased contact in a first direction by a first elastic force, in that the lever, pivotally moved from a rest position to an engagement position and acting by means of the connecting rod placed in an engaged configuration, selectively moves the sliding slide with respect to the housing from an inactive position to an active position in a second direction opposite to the first say ction and along a first axis passing between the two fixed contacts, the slide reaching its active position in the position of engagement of the lever, and in that the visible part of the hub of the lever carries a first indicator light state, itself visible from the outside of the housing in the rest position of the lever and hidden by the housing in any position the lever for which, in the engaged configuration of the connecting rod, the slide adopts a position between its active position and an intermediate position between its active and inactive positions.
Le dispositif de l'invention peut aussi comprendre un indicateur d'état mobile, adoptant une position liée à la position du coulisseau, et portant un deuxième voyant d'état masqué par le boîtier dans la position inactive du coulisseau, et visible de l'extérieur du boîtier dans toute position du coulisseau comprise entre sa position intermédiaire et sa position active.The device of the invention may also include a mobile status indicator, adopting a position linked to the position of the slide, and carrying a second status indicator masked by the housing in the inactive position of the slide, and visible from the outside the housing in any position of the slide between its intermediate position and its active position.
Cet indicateur d'état mobile peut avantageusement porter aussi un troisième voyant d'état visible de l'extérieur du boîtier dans la position inactive du coulisseau, et masqué par le boîtier dans toute position du coulisseau comprise entre sa position intermédiaire et sa position active .This mobile status indicator can advantageously also carry a third status indicator visible from the outside of the housing in the inactive position of the slider, and masked by the housing in any position of the slider comprised between its intermediate position and its active position.
Dans ce cas, le boîtier et le troisième voyant d'état sont par exemple de même couleur, tandis que le premier voyant d'état, le deuxième voyant d'état, et le boîtier sont tous trois de couleurs différentes.In this case, the housing and the third status indicator are for example of the same color, while the first status indicator, the second status indicator, and the housing are all three of different colors.
L'invention est particulièrement utile dans le cas où la manette présente un moyen de couplage, le dispositif de l'invention prenant la forme d'un module sélectivement associé à au moins un autre module équivalent et les manettes des modules associés étant couplées les unes aux autres par 1 ' intermédiaire au moins des moyens de couplage et adoptant toutes la même position. Une première extrémité de la bielle peut être articulée sur l'excentrique tandis qu'une seconde extrémité de la bielle est sélectivement maintenue, dans la configuration engagée de la bielle, dans un œil défini dans une lumière allongée du coulisseau.The invention is particularly useful in the case where the handle has a coupling means, the device of the invention taking the form of a module selectively associated with at least one other equivalent module and the handles of the associated modules being coupled together. to the others by at least one of the coupling means and all adopting the same position. A first end of the connecting rod can be articulated on the eccentric while a second end of the connecting rod is selectively held, in the engaged configuration of the connecting rod, in an eye defined in an elongated lumen of the slide.
Dans ce cas, les moyens de déclenchement comprennent par exemple un mécanisme de transmission et un verrou à levier basculant, ce verrou étant monté sur le coulisseau et comportant un premier levier basculant sélectivement commandé par le mécanisme de transmission pour débrayer le coulisseau de l' actionneur en plaçant la bielle dans une configuration désengagée, dans laquelle la deuxième extrémité de cette bielle est libérée de l'œil et coulisse librement dans la lumière allongée du coulisseau.In this case, the triggering means comprise for example a transmission mechanism and a tilting lever lock, this lock being mounted on the slide and comprising a first tilting lever selectively controlled by the transmission mechanism to disengage the slide from the actuator. by placing the connecting rod in a disengaged configuration, in which the second end of this connecting rod is released from the eye and slides freely in the elongated lumen of the slide.
De préférence, le contact mobile est porté avec une liberté de coulissement par le coulisseau et sollicité, par rapport au coulisseau, par une seconde force élastique exercée suivant la seconde direction, ce contact mobile étant, dans la position active du coulisseau, appliqué par la seconde force élastique sur les contacts fixes, et étant, dans la position inactive du coulisseau, appliqué par la seconde force élastique sur une butée du coulisseau et dégagé des contacts fixes.Preferably, the movable contact is carried with freedom of sliding by the slider and urged, relative to the slider, by a second elastic force exerted in the second direction, this movable contact being, in the active position of the slider, applied by the second elastic force on the fixed contacts, and being, in the inactive position of the slide, applied by the second elastic force on a stop of the slide and released from the fixed contacts.
On peut ainsi prévoir que le verrou à levier basculant adopte sélectivement une configuration verrouillée et une configuration déverrouillée, et que, dans la configuration verrouillée, le premier levier se trouve, sous l'effet d'une troisième force élastique, dans une première position relative de rotation par rapport au coulisseau dans laquelle ce premier levier définit sélectivement la configuration engagée de la bielle par maintien de la seconde extrémité de cette bielle dans l'œil cet œil étant délimité d'un côté par une découpe de ce premier levier et d'un autre côté par une première pente formée par une première extrémité de la lumière du coulisseau et présentant une inclinaison non nulle par rapport au premier axe.It can thus be provided that the tilting lever lock selectively adopts a locked configuration and an unlocked configuration, and that, in the locked configuration, the first lever is, under the effect of a third elastic force, in a first relative position of rotation with respect to the slide in which this first lever selectively defines the engaged configuration of the connecting rod by holding the second end of this connecting rod in the eye, this eye being delimited on one side by a cutout of this first lever and on the other hand by a first slope formed by a first end of the light of the slide and having a non-zero inclination relative to the first axis.
Dans la configuration déverrouillée, le premier levier est alors placé, par le mécanisme de transmission agissant à 1 ' encontre de la troisième force élastique, dans une seconde position relative de rotation par rapport au coulisseau, dans laquelle l'œil est ouvert par éloignement relatif de la découpe du premier levier et de la première pente et permet à la bielle de passer de sa configuration engagée à sa configuration désengagée par glissement de sa seconde extrémité sur la première pente et libre coulissement de cette seconde extrémité dans la lumière du coulisseau sur une partie au moins de la course dont dispose le coulisseau entre sa position active et sa position inactive.In the unlocked configuration, the first lever is then placed, by the transmission mechanism acting against the third elastic force, in a second relative position of rotation relative to the slide, in which the eye is opened by relative distance cutting the first lever and the first slope and allows the rod to pass from its engaged configuration to its disengaged configuration by sliding its second end on the first slope and free sliding of this second end in the lumen of the slide on a at least part of the travel available to the slide between its active position and its inactive position.
De préférence, lors du passage de la manette de sa position de repos à sa position d'enclenchement et dans la configuration engagée de la bielle, cette bielle passe par une position intermédiaire dans laquelle elle est alignée sur le premier axe par ses première et seconde extrémités . Par ailleurs, il est avantageux de faire en sorte que la découpe du premier levier présente une deuxième pente et que, dans la position d'enclenchement de la manette et pour la configuration engagée de la bielle, la deuxième extrémité de la bielle exerce, sur les première et deuxième pentes, des première et deuxième forces d'appui respectives dont la première est supérieure à la deuxième et par exemple au moins égale au double de la deuxième.Preferably, when the lever passes from its rest position to its latching position and in the engaged configuration of the connecting rod, this connecting rod passes through an intermediate position in which it is aligned on the first axis by its first and second extremities. Furthermore, it is advantageous to ensure that the cutout of the first lever has a second slope and that, in the position of engagement of the lever and for the engaged configuration of the connecting rod, the second end of the connecting rod exerts, on the first and second slopes, respective first and second support forces, the first of which is greater than the second and for example at least twice the second.
II peut aussi être judicieux de prévoir que la manette soit sollicitée vers sa position de repos par une quatrième force élastique, et que la découpe du premier levier soit bordée par une troisième pente de faible inclinaison par rapport à la bielle en configuration désengagée, de sorte que, dans la position d'enclenchement de la manette et la configuration désengagée de la bielle, la deuxième extrémité de cette bielle fasse transitoirement passer le premier levier de sa première à sa deuxième position relative de rotation, sous l'effet de la quatrième force élastique, en glissant avec appui sur la troisième pente.It may also be wise to provide that the lever is urged towards its rest position by a fourth elastic force, and that the cutout of the first lever is bordered by a third slope of slight inclination relative to the connecting rod in the disengaged configuration, so that, in the position of engagement of the lever and the disengaged configuration of the connecting rod, the second end of this connecting rod temporarily causes the first lever to pass from its first to its second relative position of rotation, under the effect of the fourth force elastic, sliding with support on the third slope.
Dans le mode de réalisation préféré de l'invention, la bielle est constituée par un cavalier conformé en "U" présentant des première et seconde branches latérales constituant respectivement les première et seconde extrémités de cette bielle et réunies entre elles par une base commune.In the preferred embodiment of the invention, the connecting rod is constituted by a rider shaped as a "U" having first and second lateral branches respectively constituting the first and second ends of this connecting rod and joined together by a common base.
Le mécanisme de transmission peut comprendre un deuxième levier monté basculant dans le boîtier et présentant un relief sélectivement entraîné, par exemple par un pion mobile externe saillant dans le boîtier à travers une première fenêtre pratiquée dans ce boîtier, et une liaison cinématique déterminant la position de rotation du premier levier en fonction au moins d'une position de rotation du deuxième levier, cette liaison cinématique incluant au moins un ergot d'entraînement porté par ce deuxième levier.The transmission mechanism may include a second lever mounted tilting in the housing and having a selectively driven relief, for example by a pin external mobile projecting into the housing through a first window formed in this housing, and a kinematic connection determining the rotational position of the first lever as a function of at least one rotational position of the second lever, this kinematic connection including at least one lug drive carried by this second lever.
La liaison cinématique peut en outre comprendre un troisième levier monté basculant dans le boîtier, ce troisième levier étant sélectivement entraîné par le deuxième levier et comprenant un doigt d'entraînement en appui sur le premier levier ainsi qu'une rainure dans laquelle l'ergot d'entraînement du deuxième levier est reçu à coulissement, les deuxième et troisième leviers effectuant des mouvements de rotation respectifs de moindre amplitude angulaire et de plus grande amplitude angulaire lors du passage du premier levier de sa première à sa seconde position relative de rotation.The kinematic connection may further comprise a third lever mounted to tilt in the housing, this third lever being selectively driven by the second lever and comprising a drive finger bearing on the first lever as well as a groove in which the lug of drive of the second lever is received by sliding, the second and third levers carrying out respective rotational movements of less angular amplitude and greater angular amplitude during the passage of the first lever from its first to its second relative position of rotation.

Comme indiqué précédemment, l'invention concerne un dispositif de coupure de courant électrique, et plus précisément un interrupteur sectionneur susceptible d'être déclenché par un organe auxiliaire (non représenté) .As indicated above, the invention relates to an electrical current cut-off device, and more specifically to a disconnector switch capable of being triggered by an auxiliary member (not shown).
Ce dispositif, qui se présente sous la forme d'un module, comprend un boîtier 1 par exemple formé d'un fond la et d'un couvercle lb.This device, which is in the form of a module, comprises a housing 1, for example formed from a bottom 1a and a cover 1b.
Le boîtier 1 porte deux contacts fixes 21 et 22, rivetés sur des supports conducteurs respectifs 21a et 22a et associés à des serre-fils respectifs 21b et 22b, dans lesquels des conducteurs d'entrée et de sortie (non représentés) sont maintenus prisonniers par le serrage de vis correspondantes 21c et 22c. Le contact électrique entre les conducteurs d'entrée et de sortie peut être établi ou interrompu au moyen d'un contact mobile 20.The housing 1 carries two fixed contacts 21 and 22, riveted on respective conductive supports 21a and 22a and associated with respective wire clamps 21b and 22b, in which input and output conductors (not shown) are held captive by tightening corresponding screws 21c and 22c. The electrical contact between the input and output conductors can be established or interrupted by means of a movable contact 20.
Plus précisément, le contact mobile 20 est sélectivement appliqué sur les contacts fixes 21 et 22 au moyen d'un mécanisme d'armement 3, et dégagé des contacts fixes 21 et 22 par des moyens de déclenchement 4.More specifically, the movable contact 20 is selectively applied to the fixed contacts 21 and 22 by means of an arming mechanism 3, and released from the fixed contacts 21 and 22 by tripping means 4.
Comme le montre notamment la figure 1, le mécanisme d'armement 3 comprend un actionneur 31 et un coulisseau d' entraînement 32.As shown in particular in FIG. 1, the arming mechanism 3 comprises an actuator 31 and a drive slide 32.
Le coulisseau 32, qui porte le contact mobile 20, est soumis d'une part à la sollicitation d'une force élastique exercée par un premier ressort 51 suivant la direction Dl (vers le haut sur les figures), et d'autre part à la force d'entraînement que l' actionneur 31 peut exercer sur lui, dans certaines conditions, suivant la direction D2 inverse de la première direction Dl (et donc vers le bas sur les figures) .The slide 32, which carries the movable contact 20, is subjected on the one hand to the stress of an elastic force exerted by a first spring 51 in the direction D1 (upwards in the figures), and on the other hand to the driving force that the actuator 31 can exert on it, under certain conditions, in the direction D2 opposite to the first direction Dl (and therefore down in the figures).
Le coulisseau peut ainsi être déplacé en translation par rapport au boîtier 1, le long d'un axe Z passant entre les deux contacts fixes 21 et 22, depuis une position inactive illustrée à la figure 3 jusque dans une position active illustrée à la figure 2 sous l'effet de l' actionneur 31, et, depuis sa position active jusque dans sa position inactive sous l'effet du ressort 51.The slide can thus be moved in translation relative to the housing 1, along an axis Z passing between the two fixed contacts 21 and 22, from an inactive position illustrated in FIG. 3 until in an active position illustrated in FIG. 2 under the effect of the actuator 31, and, from its active position to its inactive position under the effect of the spring 51.
Pour assurer un contact électrique optimal dans la position active du coulisseau 32, le contact mobile 20 est porté par le coulisseau 32 avec une liberté de coulissement et soumis, par rapport au coulisseau 32, à la sollicitation d'une force élastique exercée par un second ressort 52 suivant la seconde direction D2. Dans la position active du coulisseau 32, le contact mobile 20 est ainsi appliqué sur les contacts fixes 21 et 22 par le ressort 52, alors que, dans la position inactive du coulisseau 32, le contact mobile 20 est appliqué par le ressort 52 sur une butée 321 du coulisseau, adoptant ainsi une position dans laquelle il est dégagé des contacts fixes 21 et 22.To ensure optimal electrical contact in the active position of the slide 32, the movable contact 20 is carried by the slide 32 with freedom of sliding and subjected, with respect to the slide 32, to the stress of an elastic force exerted by a second spring 52 in the second direction D2. In the active position of the slide 32, the movable contact 20 is thus applied to the fixed contacts 21 and 22 by the spring 52, while, in the inactive position of the slide 32, the movable contact 20 is applied by the spring 52 to a stop 321 of the slide, thus adopting a position in which it is released from the fixed contacts 21 and 22.
Des butées telles que 13 (figures 2 et 3) sont par exemple prévues dans le boîtier 1 pour limiter la course du contact mobile 20 et du coulisseau 32 sous l'effet de la force exercée par le ressort 51.Stops such as 13 (Figures 2 and 3) are for example provided in the housing 1 to limit the travel of the movable contact 20 and of the slide 32 under the effect of the force exerted by the spring 51.
Selon une caractéristique importante de l'invention, les moyens de déclenchement 4 comprennent un mécanisme de transmission 41, et un verrou 42 monté sur le coulisseau 32.According to an important characteristic of the invention, the trigger means 4 comprise a transmission mechanism 41, and a lock 42 mounted on the slide 32.
Le verrou 42 , qui peut être commandé à tout moment par le mécanisme de transmission 41 pour débrayer le coulisseau 32 de 1 'actionneur 31, comporte essentiellement un levier 421 monté basculant sur le coulisseau 32 autour d'un axe X.The latch 42, which can be controlled at any time by the transmission mechanism 41 to disengage the slider 32 of the actuator 31, essentially comprises a lever 421 pivotally mounted on the slider 32 around an axis X.
Ce levier basculant (figures 4a, 4b et 8a, 8b) , qui est par exemple conformé en chape et qui coiffe l'extrémité supérieure du coulisseau 32, est en permanence sollicité par un ressort 53 vers une première position relative de rotation par rapport au coulisseau 32, bien visible sur la figure 8a. Le verrou 42 adopte alors une configuration qui sera dite "verrouillée" .This tilting lever (Figures 4a, 4b and 8a, 8b), which is for example shaped as a yoke and which covers the upper end of the slide 32, is permanently biased by a spring 53 towards a first relative position of rotation relative to the slide 32, clearly visible in FIG. 8a. The lock 42 then adopts a configuration which will be called "locked".
De son côté, 1 ' actionneur 31 (figure 1) comprend une manette 311 montée pivotante sur le boîtier 1 par l'intermédiaire d'un moyeu 311a, un excentrique 312 solidaire de la manette 311, et une bielle 313.For its part, the actuator 31 (FIG. 1) comprises a lever 311 pivotally mounted on the housing 1 by means of a hub 311a, an eccentric 312 integral with the lever 311, and a connecting rod 313.
La bielle 313 est par exemple constituée par un cavalier conformé en "U" présentant deux branches latérales extrêmes 313a et 313b réunies entre elles par une base commune 313c, les branches 313a et 313b constituant respectivement les extrémités supérieure et inférieure de cette bielle 313.The connecting rod 313 is for example constituted by a jumper shaped as a "U" having two extreme lateral branches 313a and 313b joined together by a common base 313c, the branches 313a and 313b respectively constituting the upper and lower ends of this connecting rod 313.
Bien sûr, comme le comprendra aisément l'homme du métier, les appellations "supérieure" et "inférieure" sont conventionnelles au sens où elles sont relatives à une orientation particulière du dispositif.Of course, as will easily be understood by those skilled in the art, the terms "upper" and "lower" are conventional in the sense that they relate to a particular orientation of the device.
Comme le montrent les figures 2 et 3, l'extrémité supérieure 313a de la bielle 313 est articulée sur l'excentrique 312, tandis que l'extrémité inférieure 313b de cette bielle est engagée dans une lumière allongée 322 du coulisseau 32.As shown in FIGS. 2 and 3, the upper end 313a of the connecting rod 313 is articulated on the eccentric 312, while the lower end 313b of this connecting rod is engaged in an elongated opening 322 of the slide 32.
La lumière 322 est sensiblement parallèle à l'axe Z dans sa partie inférieure mais présente, dans sa partie supérieure, une déviation faisant apparaître une pente 323 inclinée par rapport à l'axe Z. Le levier basculant 421 présente quant à lui une découpe 420 qui, dans la configuration verrouillée du verrou 42, coopère avec la partie supérieure inclinée de la lumière 322 pour définir un œil 320, de préférence fermé, dans laquelle l'extrémité inférieure 313b de la bielle 313 peut être retenue prisonnière.The light 322 is substantially parallel to the axis Z in its lower part but has, in its upper part, a deviation showing a slope 323 inclined relative to the axis Z. The tilting lever 421 has a cutout 420 which, in the locked configuration of the lock 42, cooperates with the inclined upper part of the slot 322 to define an eye 320, preferably closed, in which the lower end 313b of the connecting rod 313 can be held captive.
Ainsi, lorsque la bielle 313 adopte une configuration qui sera dite "engagée" et qui est définie par le fait que la bielle est retenue prisonnière dans l'œil 320 par son extrémité inférieure 313b, cette extrémité 313b se trouve maintenue, dans l'œil 320, d'un côté par la découpe 420 du levier basculant 421 et d'un autre côté par la pente 323, d'inclinaison non nulle par rapport à l'axe Z, que forme l'extrémité supérieure de la lumière 322 du coulisseau 32.Thus, when the connecting rod 313 adopts a configuration which will be called "engaged" and which is defined by the fact that the connecting rod is held captive in the eye 320 by its lower end 313b, this end 313b is maintained, in the eye 320, on one side by the cutout 420 of the rocking lever 421 and on the other side by the slope 323, of non-zero inclination relative to the axis Z, which forms the upper end of the light 322 of the slide 32.
Cependant, comme le montre la figure 8b, le levier basculant 421 peut être déplacé par le mécanisme de transmission 41, agissant à 1 ' encontre du ressort 53, jusqu'à atteindre une autre position relative de rotation par rapport au coulisseau 32 dans laquelle l'œil 320 s'ouvre par éloignement relatif de la découpe 420 du levier basculant 421 et de la pente 323 de la lumière 322 du coulisseau 32, le verrou 42 adoptant alors une configuration qui sera dite "déverrouillée" .However, as shown in FIG. 8b, the rocking lever 421 can be moved by the transmission mechanism 41, acting against the spring 53, until it reaches another relative position of rotation relative to the slide 32 in which the eye 320 opens by relative distance from the cutout 420 of the rocking lever 421 and the slope 323 of the light 322 of the slider 32, the latch 42 then adopting a configuration which will be called "unlocked".
Dans ces conditions, si la bielle 313 est dans sa configuration engagée à 1 ' instant où le verrou 42 passe de sa configuration verrouillée à sa configuration déverrouillée, cette situation étant précisément celle qu'illustre la figure 8a, alors l'extrémité inférieure 313b de cette bielle glisse sur la pente 323 sous l'effet de la force exercée au moins par le ressort 51 qui pousse le coulisseau 32 vers le haut, et coulisse librement dans la lumière 322 du coulisseau 32 sur une partie au moins de la course dont dispose ce coulisseau entre sa position active et sa position inactive.Under these conditions, if the connecting rod 313 is in its engaged configuration at the instant when the latch 42 changes from its locked configuration to its unlocked configuration, this situation being precisely that illustrated in FIG. 8a, then the lower end 313b of this connecting rod slides on the slope 323 under the effect of the force exerted at least by the spring 51 which pushes the slider 32 upwards, and slides freely in the light 322 of the slider 32 over at least part of the stroke which this slide has between its active position and its inactive position.
La bielle 313 passe ainsi de sa configuration engagée à une configuration qui sera dite "désengagée" .The rod 313 thus passes from its engaged configuration to a configuration which will be called "disengaged".
Lorsque la bielle est dans sa configuration désengagée, le coulisseau 32 est donc débrayé de l' actionneur 31 et retourne dans sa .position inactive puisqu'il n'est plus soumis qu'à la force du ressort 51.When the connecting rod is in its disengaged configuration, the slide 32 is therefore disengaged from the actuator 31 and returns to its inactive position since it is no longer subjected to the force of the spring 51.
En revanche, quand la bielle 313 est dans sa configuration engagée, l' actionneur 31 peut, par l'intermédiaire de cette bielle, entraîner le coulisseau 32 vers sa position active dans la direction D2 (en l'occurrence vers le bas) par pivotement de la manette 311 depuis sa position de repos (figure 3) vers sa position d'enclenchement (figure 2), la position d'enclenchement de la manette 311 plaçant le coulisseau 32 dans sa position active.On the other hand, when the connecting rod 313 is in its engaged configuration, the actuator 31 can, via this connecting rod, drive the slide 32 towards its active position in the direction D2 (in this case down) by pivoting of the handle 311 from its rest position (Figure 3) to its engagement position (Figure 2), the engagement position of the handle 311 placing the slide 32 in its active position.
Les figures 8a et 8b, qui montrent que le doigt d'entraînement 412a peut glisser sur le premier levier 421 lors du déclenchement, permettent de souligner l'importance que revêt le montage du verrou à levier basculant sur le coulisseau. En effet, en utilisant ce même montage, et en laissant au doigt d'entraînement 412a la possibilité de glisser par rapport au levier 421, il serait concevable d'entraîner le doigt 412a en translation plutôt qu'en rotation, par exemple en le fixant sur une crémaillère mue en translation par un pignon lui-même entraîné en rotation à travers la fenêtre en arc de cercle 11.FIGS. 8a and 8b, which show that the drive finger 412a can slide on the first lever 421 during the triggering, make it possible to emphasize the importance of the mounting of the lever lever lock tilting on the slide. Indeed, using this same assembly, and leaving the driving finger 412a the possibility of sliding relative to the lever 421, it would be conceivable to drive the finger 412a in translation rather than in rotation, for example by fixing it on a rack moved in translation by a pinion itself driven in rotation through the window in an arc of a circle 11.
Selon encore une autre variante, le mouvement de translation du doigt 412a pourrait être directement imprimé de l'extérieur du boîtier à travers une fenêtre telle que 11, mais de forme rectiligne.According to yet another variant, the translational movement of the finger 412a could be directly printed from the outside of the housing through a window such as 11, but of rectilinear shape.
Il apparaît ainsi que le montage du verrou à levier basculant sur le coulisseau dépasse en fait l'objectif premier de l'invention, à savoir de permettre l'utilisation d'un mouvement de déclenchement en arc de cercle pour provoquer le mouvement rectiligne du coulisseau, et autorise une grande variété de transformations de mouvements.It thus appears that the mounting of the lever lever tilting on the slide actually exceeds the primary objective of the invention, namely to allow the use of a tripping movement in an arc of a circle to cause the rectilinear movement of the slide , and allows a wide variety of movement transformations.
Pour assurer la stabilité des positions active et inactive du coulisseau 32, l' actionneur 31 présente un agencement du type connu de l'homme du métier sous la dénomination de blocage "à genouillère" ou "à point mort dépassé", défini par le fait que, lorsque la manette 311, en configuration engagée de la bielle, passe de sa position de repos à sa position d'enclenchement, cette bielle passe par une position intermédiaire dans laquelle la compression du ressort 51 est maximale, le segment de droite formé par les extrémités 313a et 313b de cette bielle étant alors aligné sur l'axe Z, sur lequel se trouve également le centre de rotation de 1 ' excentrique 312.To ensure the stability of the active and inactive positions of the slider 32, the actuator 31 has an arrangement of the type known to those skilled in the art under the name of "toggle" or "dead center exceeded" blocking, defined by the fact that, when the lever 311, in the engaged configuration of the connecting rod, passes from its rest position to its latching position, this connecting rod passes through an intermediate position in which the compression of the spring 51 is maximum, the straight segment formed by the ends 313a and 313b of this connecting rod then being aligned on the axis Z, on which is also finds the center of rotation of the eccentric 312.
Comme le montre le mieux la figure 4a, la découpe 420 du premier levier 421 présente une pente 420a destinée à supporter, avec la pente 323 de la lumière 322 du coulisseau 32, l'effort d'appui que l'extrémité 313b de la bielle, dans la configuration engagée de celle-ci, exerce sur l'œil 320 dans la position d'enclenchement de la manette 311.As best shown in Figure 4a, the cutout 420 of the first lever 421 has a slope 420a intended to support, with the slope 323 of the light 322 of the slide 32, the bearing force that the end 313b of the connecting rod , in the engaged configuration thereof, exerts on the eye 320 in the engagement position of the lever 311.
Cependant, pour donner à la force de déclenchement, qui fait passer le levier 421 de sa première à sa seconde position relative de rotation, une valeur aussi modérée que possible, il est fait en sorte que la pente 420a de la découpe 420 fasse alors avec la direction de la bielle 313 (figure 2) un angle sensiblement inférieur à celui que fait, avec cette même direction, la pente 323 de la lumière 322 du coulisseau.However, to give the tripping force, which moves the lever 421 from its first to its second relative position of rotation, as moderate as possible, it is made so that the slope 420a of the cutout 420 then makes with the direction of the rod 313 (Figure 2) an angle substantially less than that made, with this same direction, the slope 323 of the light 322 of the slide.
De cette manière, l'extrémité 313b de la bielle 313 exerce, sur les pentes 323 et 420a, des première et deuxième forces d'appui respectives dont la première est sensiblement supérieure à la deuxième, et par exemple au moins égale au double de la force d'appui exercée sur la pente 420a.In this way, the end 313b of the connecting rod 313 exerts, on the slopes 323 and 420a, respective first and second support forces, the first of which is substantially greater than the second, and for example at least twice the bearing force exerted on the slope 420a.
Par ailleurs, la découpe 420 du premier levier 421 est bordée par une autre pente 420b (figure 4a) , de faible inclinaison par rapport à la bielle 313 en configuration désengagée, et la manette est sollicitée vers sa position de repos par un ressort 54. Ainsi, dans la position d'enclenchement de la manette 311 et dans la configuration désengagée de la bielle 313, l'extrémité inférieure 313b de cette bielle 313 s'appuie en glissant sur la pente 420b sous l'effet de la force exercée par le ressort 54 et soulève le premier levier 421, le faisant transitoirement passer de sa première à sa deuxième position relative de rotation, jusqu'à revenir prisonnière de l'œil 320.Furthermore, the cutout 420 of the first lever 421 is bordered by another slope 420b (FIG. 4a), of slight inclination relative to the rod 313 in the disengaged configuration, and the lever is biased towards its rest position by a spring 54. Thus, in the engagement position of the lever 311 and in the disengaged configuration of the connecting rod 313, the lower end 313b of this connecting rod 313 is supported by sliding on the slope 420b under the effect of the force exerted by the spring 54 and raises the first lever 421, temporarily passing it from its first to its second relative position of rotation, until it returns trapped in the eye 320.
Le mécanisme de transmission 41 comprend par exemple au moins un deuxième levier 411 et une liaison cinématique.The transmission mechanism 41 comprises for example at least a second lever 411 and a kinematic link.
Le deuxième levier 411 (figures 1 à 3 et 6a, 6b) est monté basculant dans le boîtier 1 et présente un relief 411a, par exemple une rainure, qui peut être entraîné à volonté par un pion mobile externe (non représenté) , appartenant à un module auxiliaire adjacent au dispositif de 1 ' invention, et saillant dans le boîtier 1 à travers une fenêtre 11 en arc de cercle pratiquée dans ce boîtier 1.The second lever 411 (Figures 1 to 3 and 6a, 6b) is pivotally mounted in the housing 1 and has a relief 411a, for example a groove, which can be driven at will by an external movable pin (not shown), belonging to an auxiliary module adjacent to the device of the invention, and projecting into the housing 1 through a window 11 in an arc formed in this housing 1.
La liaison cinématique, dont le rôle est de déterminer la position de rotation du premier levier 421 en fonction de la position de rotation du deuxième levier 411, comprend au moins un ergot d'entraînement 411b porté par ce deuxième levier 411, mais peut aussi comprendre un troisième levier 412 monté basculant dans le boîtier 1 (figures 1 à 3 et 7) .The kinematic link, the role of which is to determine the position of rotation of the first lever 421 as a function of the position of rotation of the second lever 411, comprises at least one drive pin 411b carried by this second lever 411, but can also include a third lever 412 mounted tilting in the housing 1 (Figures 1 to 3 and 7).
Ce troisième levier 412, qui est destiné à être entraîné par le deuxième levier 411, comprend alors lui-même un doigt d'entraînement 412a en appui sur le premier levier 421 ainsi qu'une rainure 412b dans laquelle l'ergot d'entraînement 411b du deuxième levier 411 est reçu à coulissement .This third lever 412, which is intended to be driven by the second lever 411, then itself comprises a drive finger 412a bearing on the first lever 421 as well as a groove 412b in which the drive lug 411b of the second lever 411 is slidably received.
Le rôle de ce troisième levier 412 est d'amplifier le mouvement angulaire du deuxième levier 411, c'est-à-dire que, lorsque le premier levier 421 passe de sa première position relative de rotation (figure 8a) à sa seconde position relative de rotation (figure 8b) , le troisième levier basculant 412 effectue un mouvement de rotation de plus grande amplitude angulaire que le mouvement de rotation qu'effectue le deuxième levier basculant 411.The role of this third lever 412 is to amplify the angular movement of the second lever 411, that is to say that, when the first lever 421 passes from its first relative position of rotation (FIG. 8a) to its second relative position of rotation (FIG. 8b), the third rocking lever 412 performs a rotational movement of greater angular amplitude than the rotational movement effected by the second rocking lever 411.
Le moyeu 311a de la manette 311 est monté à rotation dans le boîtier 1, comme illustré à la figure 2, de manière qu'une partie de ce moyeu soit visible de l'extérieur du boîtier 1, même si ce dernier est opaque, ce qui correspond au mode de réalisation préféré de l'invention.The hub 311a of the lever 311 is rotatably mounted in the housing 1, as illustrated in FIG. 2, so that part of this hub is visible from the outside of the housing 1, even if the latter is opaque, this which corresponds to the preferred embodiment of the invention.
La partie visible du moyeu 311a porte un premier voyant d'état 61 (figure 3), destiné à informer l'utilisateur du dispositif de l'invention que le circuit électrique commandé par ce dispositif est ouvert, autrement dit que le contact mobile 20 est dégagé des contacts fixes 21 et 22.The visible part of the hub 311a carries a first status indicator 61 (FIG. 3), intended to inform the user of the device of the invention that the electrical circuit controlled by this device is open, in other words that the movable contact 20 is free from fixed contacts 21 and 22.
Pour ce faire, le voyant d'état 61 est lui-même visible de 1 ' extérieur du boîtier 1 dans la position de repos de la manette 311. En revanche, le voyant d'état 61 est masqué par la paroi latérale opaque du boîtier 1 dans toute position de la manette 311 pour laquelle, en configuration engagée de la bielle 313, le coulisseau 32 adopte une position comprise entre sa position active et une position intermédiaire entre ses positions active et inactive.To do this, the status indicator 61 is itself visible from the outside of the housing 1 in the rest position of the lever 311. On the other hand, the status indicator 61 is hidden by the opaque side wall of the housing 1 in any position of the lever 311 for which, in the engaged configuration of the connecting rod 313, the slider 32 adopts a position between its active position and a intermediate position between its active and inactive positions.
Le dispositif de l'invention comprend aussi avantageusement un indicateur d'état mobile 60, qui adopte en permanence une position liée à la position du coulisseau 32.The device of the invention also advantageously comprises a mobile status indicator 60, which permanently adopts a position linked to the position of the slide 32.
Par exemple, cet indicateur 60 prend lui aussi la forme d'un levier monté basculant sur le boîtier 1 et est doté d'une came 600 dans laquelle coulisse un doigt 325 (figure 2) solidaire d'une extension 324 (figure 5) du coulisseau 32.For example, this indicator 60 also takes the form of a lever pivotably mounted on the housing 1 and is provided with a cam 600 in which a finger 325 (FIG. 2) slides secured to an extension 324 (FIG. 5) of the slide 32.
L'indicateur d'état 60 porte un deuxième voyant d'état 62, destiné à informer l'utilisateur du dispositif de 1 ' invention que le circuit électrique commandé par ce dispositif est fermé, autrement dit que le contact mobile 20 est appliqué par le ressort 52 sur les contacts fixes 21 et 22.The status indicator 60 carries a second status indicator 62, intended to inform the user of the device of the invention that the electrical circuit controlled by this device is closed, in other words that the movable contact 20 is applied by the spring 52 on the fixed contacts 21 and 22.
Pour ce faire, le deuxième voyant d'état 62 est masqué par la paroi latérale du boîtier 1 dans la position inactive du coulisseau 32, mais visible de l'extérieur du boîtier 1, par exemple à travers une fenêtre 12 de ce boîtier (figure 1) , dans toute position du coulisseau 32 comprise entre sa position intermédiaire et sa position active. De préférence, les premier et deuxième voyants d'état 61 et 62 sont de couleurs différentes entre eux, par exemple respectivement vert et rouge, et d'une couleur différente de celle du boîtier 1, par exemple jaune, de manière à permettre une discrimination optimale des états signalés par ces voyants .To do this, the second status indicator 62 is hidden by the side wall of the housing 1 in the inactive position of the slider 32, but visible from the outside of the housing 1, for example through a window 12 of this housing (FIG. 1), in any position of the slide 32 between its intermediate position and its active position. Preferably, the first and second status indicators 61 and 62 are of different colors between them, for example green and red respectively, and of a different color from that of the housing 1, for example yellow, so as to allow discrimination optimal of the states indicated by these indicators.
L'indicateur d'état mobile 60 peut en outre porter un troisième voyant d'état 63, particulièrement avantageux dans le cas où le module que constitue le dispositif de l'invention est couplé à d'autres modules adjacents au moyen d'une barre (non représentée) insérée dans l'ouverture 310 du moyeu 311a de chacun des modules couplés .The mobile status indicator 60 can also carry a third status indicator 63, which is particularly advantageous in the case where the module which constitutes the device of the invention is coupled to other adjacent modules by means of a bar. (not shown) inserted into the opening 310 of the hub 311a of each of the coupled modules.
Dans ce cas, en effet, les manettes 311 des différents modules couplés adoptent toutes la même position, alors même que les coulisseaux 32 respectifs de ces différents modules peuvent être dans des positions différentes.In this case, in fact, the levers 311 of the different coupled modules all adopt the same position, even though the respective slides 32 of these different modules can be in different positions.
En particulier, si après déclenchement de tous les modules couplés, le contact mobile 20 de l'un de ces modules reste, par suite de défaillance, soudé aux contacts fixes 21 et 22 de ce module, les coulisseaux de tous les modules non défaillants seront en position inactive, tandis que le coulisseau du module défaillant restera en position active.In particular, if after tripping of all the coupled modules, the movable contact 20 of one of these modules remains, as a result of failure, soldered to the fixed contacts 21 and 22 of this module, the slides of all the non-failing modules will be in the inactive position, while the slide of the faulty module will remain in the active position.
En revanche, les manettes de tous les modules, au lieu de retourner dans leur position de repos, resteront dans une position moyenne correspondant à la position de la manette du module défectueux, et dans laquelle le premier voyant 61 restera masqué par le boîtier 1. Pour permettre une discrimination du module défaillant et des modules non défaillants, le troisième voyant d'état 63 peut être porté par l'indicateur d'état mobile 60 de manière à être visible de l'extérieur du boîtier 1, à travers la fenêtre 12, dans la position inactive du coulisseau 32, et masqué par le boîtier 1 dans toute position du coulisseau 32 comprise entre sa position intermédiaire et sa position active.On the other hand, the handles of all the modules, instead of returning to their rest position, will remain in an average position corresponding to the position of the handle of the defective module, and in which the first indicator 61 will remain masked by the housing 1. To allow discrimination between the failing module and the non-failing modules, the third status indicator 63 can be carried by the mobile status indicator 60 so as to be visible from the outside of the housing 1, through the window 12 , in the inactive position of the slide 32, and hidden by the housing 1 in any position of the slide 32 between its intermediate position and its active position.
De plus, ce troisième voyant d'état 63 est de préférence de la couleur du boîtier, par exemple jaune.In addition, this third status indicator 63 is preferably of the color of the housing, for example yellow.
Ainsi, dans la mesure où le coulisseau du module défaillant reste en position active, cet état est indiqué par le deuxième voyant 62 de ce modulé, de couleur rouge dans l'exemple pris ci-dessus.Thus, insofar as the slide of the faulty module remains in the active position, this state is indicated by the second LED 62 of this module, colored red in the example taken above.
En revanche, dans la mesure où les coulisseaux des modules non défaillants seront en position inactive, seul sera visible le troisième voyant 63 de ces modules, de couleur jaune dans l'exemple, puisque le premier voyant 61, de couleur verte, sera masqué par le boîtier en raison de la position moyenne prise par les manettes de 1 ' ensemble des modules couplés .On the other hand, insofar as the slides of the non-failing modules will be in the inactive position, only the third indicator 63 of these modules will be visible, yellow in the example, since the first indicator 61, of green color, will be masked by the housing due to the average position taken by the levers of one set of coupled modules.
Ainsi, non seulement l'observation des fenêtres 12 de l'ensemble des modules couplés permettra d'identifier le ou les modules éventuellement défaillants, mais l'observation de l'absence de premier voyant d'état 61 sur l'un quelconque des modules couplés révélera une anomalie touchant l'un au moins de ces modules. Comme le comprendra aisément l'homme du métier à la lecture de la description qui précède, des voyants d'état tels que 61 à 63 sont utilisables non seulement sur un dispositif de coupure de courant dans lequel le mouvement de déclenchement et le mouvement du contact mobile sont de types différents, mais plus généralement sur un dispositif de coupure de courant doté d'un actionneur tel que 31 et d'un coulisseau tel que 32, indépendamment de la forme particulière donnée aux moyens de déclenchement 4. Thus, not only the observation of the windows 12 of all of the coupled modules will make it possible to identify the module or modules possibly failing, but the observation of the absence of the first status indicator 61 on any one of the modules coupled will reveal an anomaly affecting at least one of these modules. As will readily be understood by a person skilled in the art on reading the above description, status indicators such as 61 to 63 can be used not only on a current cut-off device in which the tripping movement and the movement of the contact mobile are of different types, but more generally on a current cut-off device provided with an actuator such as 31 and a slide such as 32, independently of the particular shape given to the triggering means 4.
