Dans le brevet EP-0617449, on a proposé un appareil contacteur-disjoncteur dans lequel un mécanisme à genouillère permet de commander le pont de contacts, à partir de l'électroaimant ou de la serrure, de manière indépendante.In patent EP-0617449, a contactor-circuit breaker device has been proposed in which a toggle mechanism makes it possible to control the contact bridge, from the electromagnet or from the lock, independently.

L'appareil interrupteur de type contacteur-disjoncteur qui est illustré par les dessins comporte plusieurs pôles de puissance à double coupure. Chaque pôle de puissance comporte d'une part un jeu de contacts fixes 1 et 2 qui sont reliés à deux plages de raccordement 31 et 32 pourvues de bornes et d'autre part un pont de contacts mobiles 5 coopérant avec ces contacts fixes 1 et 2 de manière à établir ou à interrompre le passage de courant entre les bornes. Les bornes permettent de raccorder des conducteurs électriques extérieurs.The switch-type circuit breaker device which is illustrated in the drawings comprises several double-break power poles. Each power pole comprises on the one hand a set of fixed contacts 1 and 2 which are connected to two connection pads 31 and 32 provided with terminals and on the other hand a bridge of movable contacts 5 cooperating with these fixed contacts 1 and 2 so as to establish or interrupt the flow of current between the terminals. The terminals are used to connect external electrical conductors.

Le pont de contacts 5 est monté sur un support de pont en matériau isolant.The contact bridge 5 is mounted on a bridge support made of insulating material.

Les contacts fixes et l'ensemble mobile équipé du pont de contacts d'un pôle sont logés dans une cartouche isolante 7 formant la chambre de coupure et assurant l'isolement entre pôles. Les différentes cartouches 7 sont disposées, côte à côte, entre l'électroaimant 8 et la serrure 23. Chaque cartouche 7 contient, en plus des contacts fixes, du pont de contacts et du support de pont associé, des ailettes de désionisation.The fixed contacts and the movable assembly equipped with the contact bridge of a pole are housed in an insulating cartridge 7 forming the breaking chamber and ensuring the isolation between poles. The different cartridges 7 are arranged, side by side, between the electromagnet 8 and the lock 23. Each cartridge 7 contains, in addition to the fixed contacts, the contact bridge and the associated bridge support, deionization fins.

L'électroaimant 8 qui manoeuvre les contacts mobiles se compose d'un circuit magnétique fixe 9, d'un circuit magnétique 10 mobile en translation et d'une bobine 11. La bobine 11 est pourvue de bornes d'alimentation qui sont accessibles à l'extérieur du boîtier. Un ressort de rappel non représenté agit sur le circuit magnétique mobile 10.The electromagnet 8 which operates the movable contacts consists of a fixed magnetic circuit 9, a magnetic circuit 10 movable in translation and a coil 11. The coil 11 is provided with supply terminals which are accessible to the outside of the case. A return spring, not shown, acts on the mobile magnetic circuit 10.

La pièce de commande 15 des contacts est reliée par une articulation 16 à un levier de liaison 13 qui est susceptible d'être déplacé par le circuit magnétique mobile 10 de l'électroaimant. Pour s'accrocher sur le coulisseau 22 solidaire de l'armature mobile 10, l'extrémité du levier 13 présente un doigt d'accrochage 19 qui peut s'engager dans un crochet 221 du coulisseau 22 . L'extrémité démontable 19 du levier 13 est associée à une pièce de blocage ou de guidage 14 qui peut pivoter autour d'un axe 25 sur le boîtier. A cet effet, le doigt d'accrochage 19 est guidé en translation dans une glissière rectiligne 141 de la pièce de blocage 14.The control part 15 of the contacts is connected by an articulation 16 to a connection lever 13 which is capable of being moved by the mobile magnetic circuit 10 of the electromagnet. To hang on the slide 22 secured to the movable frame 10, the end of the lever 13 has a hooking finger 19 which can engage in a hook 221 of the slide 22. The removable end 19 of the lever 13 is associated with a blocking or guiding part 14 which can pivot around an axis 25 on the housing. To this end, the latching finger 19 is guided in translation in a rectilinear slide 141 of the locking piece 14.

Le contacteur-disjoncteur présente, à l'avant, une serrure 23. La pièce de commande 15 des contacts est réunie à la serrure 23 par un levier de serrure 12. Ce levier 12 est articulé, autour d'un axe 20, aux parties mobiles de la serrure 23 et est relié par un assemblage coulissant et articulé 121 à la pièce de commande 15 des contacts mobiles.The contactor-circuit breaker has, at the front, a lock 23. The control part 15 of the contacts is joined to the lock 23 by a lock lever 12. This lever 12 is articulated, around an axis 20, to the parts movable parts of the lock 23 and is connected by a sliding and articulated assembly 121 to the control part 15 of the movable contacts.

Un module de déclenchement 4 est monté sur l'appreil pour assurer les fonctions de protection.A trigger module 4 is mounted on the device to provide the protection functions.

Dans le mode de réalisation des figures 1 à 8 où les ponts de contacts sont rotatifs, le support de pont est guidé en rotation autour d'un axe de pivotement 6. La partie médiane du pont de contacts 5 se loge dans un logement du support de manière à pouvoir pivoter par rapport à ce support. La pression des contacts est obtenue par des ressorts qui tendent à déplacer le pont de contacts 5 par rapport au support.In the embodiment of Figures 1 to 8 where the contact bridges are rotatable, the bridge support is guided in rotation about a pivot axis 6. The middle part of the contact bridge 5 is housed in a housing of the support so as to be able to pivot relative to this support. The contact pressure is obtained by springs which tend to move the contact bridge 5 relative to the support.

La pièce de commande 15 des contacts est une manivelle 15 liée au support de pont et qui pivote donc autour de l'axe 6. Le débattement de cette manivelle s'effectue à l'extérieur de la cartouche.The control part 15 of the contacts is a crank 15 linked to the bridge support and which therefore pivots about the axis 6. The movement of this crank takes place outside the cartridge.

L'assemblage entre le levier de serrure 12 et la pièce de commande 15 est constitué par une tige de commande 17 qui est solidaire de la manivelle 15 et qui coulisse dans une lumière 121 du levier de serrure 12. Cet assemblage permet le débattement de la tige 17 et de la pièce 15 lors du fonctionnement en contacteur.The assembly between the lock lever 12 and the control part 15 is constituted by a control rod 17 which is integral with the crank 15 and which slides in a slot 121 of the lock lever 12. This assembly allows the movement of the rod 17 and of part 15 during operation in contactor.

Le levier de serrure 12 présente un cran 122 dans lequel peut se loger un ergot 21 de la pièce de blocage 14. Lorsque l'ergot 21 est positionné dans le cran 122, le levier de serrure 12 bloque la pièce de blocage 14. Celle-ci présente une lumière 142 permettant le débattement.The lock lever 12 has a notch 122 in which can be accommodated a lug 21 of the locking piece 14. When the lug 21 is positioned in the notch 122, the lock lever 12 blocks the locking piece 14. This this has a light 142 allowing the movement.

La tige de commande 17 traverse les différents supports de ponts et les manivelles 15. Une deuxième tige de commande 18 est prévue.The control rod 17 passes through the various bridge supports and the cranks 15. A second control rod 18 is provided.

Le coulisseau 22 a une forme en fourche dont les deux branches s'introduisent dans les deux espaces qui s'étendent chacun entre deux cartouches. Dans ces deux espaces se logent aussi les leviers de serrure 12, les pièces 15, les pièces de blocage 14 et les leviers de liaison 13.The slide 22 has a fork shape, the two branches of which are introduced into the two spaces which each extend between two cartridges. In these two spaces are also housed the lock levers 12, the parts 15, the locking parts 14 and the connection levers 13.

Le fonctionnement de l'appareil en contacteur va maintenant être expliqué.The operation of the device in contactor will now be explained.

En se référant aux figures 1 et 6, les contacts sont fermés, la serrure 23 est en position "Marche" et l'électroaimant 8 est sous tension. Cette position correspond à la position "marche" du contacteur ou du disjoncteur. Le coulisseau 22 de l'électroaimant 8 est accouplé au levier de liaison 13 qui maintient la pièce de commande 15 en position de fermeture des contacts. La pression de contact entre les contacts du pont mobile et les contacts fixes est générée par les ressorts de pression logés dans le support de pont.Referring to Figures 1 and 6, the contacts are closed, the lock 23 is in the "On" position and the electromagnet 8 is energized. This position corresponds to the "on" position of the contactor or circuit breaker. The slide 22 of the electromagnet 8 is coupled to the connection lever 13 which maintains the control part 15 in the closed position of the contacts. The contact pressure between the movable bridge contacts and the fixed contacts is generated by the pressure springs housed in the bridge support.

Lorsque la bobine de l'électroaimant n'est pas alimentée (figures 2 ou 8), le circuit magnétique mobile 10 est repoussé vers l'avant par les ressorts et le levier de liaison 13 fait pivoter la manivelle de commande 15 et les ponts de contacts 5 dans le sens d'ouverture des contacts. L'axe 19 du levier de liaison 13 est guidé par la glissière 141 de la pièce de blocage 14 qui reste immobile pendant le passage de la position de fermeture à la position d'ouverture et vice-versa. L'ouverture des pôles est produite par intervention sur le circuit de commande de la bobine ce qui est le fonctionnement normal d'un contacteur.When the solenoid coil is not energized (Figures 2 or 8), the movable magnetic circuit 10 is pushed forward by the springs and the link lever 13 rotates the control crank 15 and the bridges contacts 5 in the opening direction of the contacts. The axis 19 of the connecting lever 13 is guided by the slide 141 of the locking piece 14 which remains stationary during the passage from the closed position to the open position and vice versa. The opening of the poles is produced by intervention on the control circuit of the coil which is the normal operation of a contactor.

L'excitation de la bobine de l'électroaimant détermine le déplacement du circuit magnétique mobile 10 vers l'arrière et donc le mouvement du levier de liaison 13 et le déplacement de la pièce de commande 15 des contacts. Les contacts des ponts 5 viennent en appui sur les contacts fixes 1 et 2. Les ressorts internes aux supports de ponts mettent les contacts mobiles en pression contre les contacts fixes.The excitation of the electromagnet coil determines the displacement of the movable magnetic circuit 10 backwards and therefore the movement of the link lever 13 and the displacement of the control part 15 of the contacts. The contacts of the bridges 5 come to bear on the fixed contacts 1 and 2. The springs internal to the bridge supports put the movable contacts under pressure against the fixed contacts.

Le fonctionnement de l'appareil en disjoncteur va maintenant être expliqué.The operation of the device in circuit breaker will now be explained.

Les ordres de déclenchement en disjoncteur passent par la serrure 23 qui agit mécaniquement sur un contact. La serrure 23 peut être actionnée manuellement par le levier de commande 24 ou par le module de déclenchement 4.The circuit breaker tripping orders pass through the lock 23 which acts mechanically on a contact. The lock 23 can be actuated manually by the control lever 24 or by the trigger module 4.

On considèrera comme position initiale la position pôles fermés qui est illustrée par les figures 1 et 6. Lorsque la serrure 23 se déclenche (figures 3 et 8), elle tire le levier de serrure 12 vers l'avant. Ce levier de serrure 12 déplace la pièce 15 et les contacts mobiles. Le levier de serrure 12 libère la pièce de blocage 14 qui peut alors pivoter. La rotation de la manivelle de commande 15 provoquée par le mouvement du levier de serrure 12 entraîne le levier de liaison 13 qui fait pivoter la pièce de blocage 14 et libère l'axe 19 du cran 221. Les pôles s'ouvrent. On note qu'il n'y a plus de liaison positive entre l'électroaimant et les ponts mobiles.The closed position, which is illustrated in FIGS. 1 and 6, will be considered as the initial position. When the lock 23 is released (Figures 3 and 8), it pulls the lock lever 12 forwards. This lock lever 12 moves the part 15 and the mobile contacts. The lock lever 12 releases the blocking part 14 which can then pivot. The rotation of the control crank 15 caused by the movement of the lock lever 12 drives the link lever 13 which rotates the locking piece 14 and releases the axis 19 of the notch 221. The poles open. It is noted that there is no longer a positive connection between the electromagnet and the mobile bridges.

Pour opérer le réarmement, l'opérateur doit fermer la serrure à l'aide du levier 24 ce qui ramène le levier de serrure 12 en position arrière. L'électroaimant reste ouvert.To operate the reset, the operator must close the lock using the lever 24 which brings the lock lever 12 back. The electromagnet remains open.

Les assemblages démontables entre le levier de liaison 13 et le coulisseau 22 permettent le démontage et le remplacement de l'ensemble démontable formé des cartouches 7 et de la serrure 23. Les conducteurs montés dans les cartouches doivent au préalable être séparés des conducteurs 31 et 32 qui portent les bornes et restent montés sur le socle. Par ailleurs les axes 19 doivent être dégagés du coulisseau 22 et pour cela la serrure 23 doit être mise en position "arrêt".The removable assemblies between the link lever 13 and the slide 22 allow the dismantling and replacement of the removable assembly formed by the cartridges 7 and the lock 23. The conductors mounted in the cartridges must first be separated from the conductors 31 and 32 which carry the terminals and remain mounted on the base. Furthermore, the pins 19 must be released from the slide 22 and for this the lock 23 must be put in the "off" position.

Dans la variante des figures 9 à 11, les supports et ponts de contacts, au lieu d'être mobiles en rotation, sont mobiles en translation.In the variant of FIGS. 9 to 11, the contact supports and bridges, instead of being mobile in rotation, are mobile in translation.

Il est bien entendu que l'on peut sans sortir du cadre de l'invention, imaginer des variantes et des perfectionnements de détail et de même envisager l'emploi de moyens équivalents.It is understood that it is possible, without departing from the scope of the invention, to imagine variants and improvements in detail and even to envisage the use of equivalent means.
