Sur la figure 1, on voit un dispositif de commande D des contacts d'un appareil de coupure électrique tel un interrupteur ou un sectionneur, selon l'invention. Ce dispositif comporte un premier ensemble illustré sur la figure 2, ledit ensemble comportant un arbre à came 1 relié de manière articulé à un bâti, ledit arbre étant solidarisé en rotation à une came 2, et une bielle de guidage 3 également reliée de manière articulée audit bâti par l'une 3a dite première, de ses extrémités. Ces pièces sont reliées ensemble grâce à un galet 4 monté coulissant dans une rainure arquée 5 de la came 2 et comportant un axe 6 solidaire d'une tige 7. Cette tige 7 est montée coulissante à l'intérieur d'une cage 8 et solidarisée par son extrémité opposée à celle reliée au galet 4, au contact mobile (non représenté) de l'appareil. Cette cage 8 comporte également un logement 9 destiné à recevoir un ressort 10, ledit ressort 10 étant en appui par l'une 10a de ses extrémités sur une face interne 8a de la cage et par son extrémité opposée 10b sur une pièce 10c en appui sur une autre face 8b de la cage de manière à contribuer à assurer la pression de contact entre le contact mobile et le contact fixe. Ces pièces sont reliées ensemble de telle façon qu'une rotation de l'arbre à came entraîne un déplacement vertical de l'axe 6 du galet 4 et en conséquence du contact mobile.
Ce dispositif comporte également, tel qu'illustré sur les autres figures, une manivelle de manoeuvre 11 en liaison pivot par rapport au bâti. Cette manivelle de manoeuvre 11 est reliée de manière articulée, par l'une 11a de ses extrémités, à l'une dite première 12a des extrémités 12a,12b d'une bielle de liaison 12, ladite bielle de liaison 12 étant, à son extrémité dite seconde 12b opposée à la première, reliée de manière articulée à une manivelle d'entraînement 13 de l'arbre à came précité 1. Ce dispositif D comporte également une manivelle de compression 14 reliée de manière articulée au bâti, autour du même axe X que l'axe autour duquel est reliée au bâti la manivelle de manoeuvre 11. Cette manivelle de compression 14 comporte une extrémité 14a reliée de manière articulée à une partie d'extrémité 15a d'une bielle de guidage à ressorts 15. Cette bielle de guidage 15 comporte un ensemble de bielles permettant la compression et le guidage d'un ressort de manoeuvre 16 interposé entre ses deux parties d'extrémités 15a,15b. Cette manivelle de compression 14 comporte une butée d'entraînement d'ouverture 14c et une butée d'entraînement de fermeture 14b, comme ceci sera expliqué ultérieurement.
Ce dispositif comporte également un levier de manoeuvre L (illustré sur la figure 4) monté en rotation par rapport au bâti et apte à entraîner la manivelle de compression précitée 14.
Ce dispositif est complété par un verrou de maintien 17 d'un axe d'entraînement Y de la manivelle de manoeuvre 11, ledit axe 11 étant également l'axe d'articulation de la bielle de manoeuvre à la bielle de liaison. A cet effet, le verrou comporte une encoche 20 coopérant avec ledit axe, et est rappelé en position de verrouillage par un ressort de traction 18 relié par l'une 18a de ses extrémités au bâti, et par son extrémité opposée 18b au verrou. Le déverrouillage de l'axe Y sera réalisé par l'intermédiaire d'un doigt de levage 19 prévu sur la manivelle de compression 14.
Le fonctionnement du dispositif va être décrit dans ce qui suit en référence aux figures.
Sur la figure 3, le dispositif est dans une position ouverte. Lors d'une manoeuvre de fermeture, tel que représenté sur la figure 4, le levier L est entraîné vers le bas dans le sens antihoraire jusqu'à ce que la manivelle de compression 14 et la bielle à ressort 15 franchissent une ligne de passage de point mort P. Durant cette étape, le verrou 17 maintient l'axe d'entraînement Y de la manivelle de manoeuvre 11 dans une position dite d'ouverture des contacts.
Au-delà de la position de passage du point mort, le système est entraîné de manière autonome sous l'effet du ressort de manoeuvre 16, tel qu'illustré sur la figure 5.
Pendant cette rotation de la manivelle de compression 14 sous l'effet du ressort de manoeuvre 16, le doigt de levage 19 prévu sur ladite manivelle 14, entraîne le verrou de maintien 17 dans le sens horaire de manière que l'axe d'entraînement 11a de la manivelle de manoeuvre 11 soit libéré de l'encoche 20 prévue dans le verrou de maintien 17 dans laquelle elle était retenue. En même temps, la butée de fermeture 14b de la manivelle de compression 14 est entrée en contact avec l'axe d'entraînement Y de la manivelle de manoeuvre 11. Il s'ensuit un entraînement de la manivelle de manoeuvre 11 par la manivelle de compression 14, ce qui entraîne le mouvement de la bielle de liaison 12. Ce mouvement de la bielle de liaison 12 entraîne la manivelle d'entraînement 13 dans le sens anti-horaire, sous l'effet de la force F1 exercée par la bielle de liaison 12 et la manivelle de manoeuvre 11 (fig.5) et sous l'action F2 du ressort de manoeuvre 16. Il en résulte une rotation de l'arbre à came 1 dans le sens anti-horaire, ce qui entraîne le sous-ensemble pression de contact en mouvement jusqu'à la mise en pression des contacts fixe et mobile, puis l'arrêt du mouvement de l'arbre à came 1 par la mise en butée du galet 4 à l'intérieur de la rainure 5 de la came 2 (fig.6).
La fermeture des contacts est maintenue grâce à l'effet du ressort de manoeuvre 16. L'effort transmis sur l'arbre à came est assuré pour une partie, par l'effort exercé directement par l'extrémité inférieure 16a du ressort de manoeuvre 16, et pour une autre partie, par l'effort exercé par l'extrémité supérieure 16b du ressort 16 retransmis par la bielle de liaison 12 au contact mobile grâce à la manivelle de manoeuvre 11 et à la manivelle de compression 14. On utilise donc les efforts exercés par les deux extrémités du ressort, ceci grâce à la position du ressort intercalée entre deux parties mobiles du mécanisme pendant la manoeuvre.
La manoeuvre d'ouverture est réalisée selon les étapes suivantes :
A partir de la position fermée illustrée sur la figure 6, le levier L est entraîné vers le haut dans le sens horaire jusqu'à ce que la manivelle de compression 14 et la bielle de guidage à ressort 15 franchissent la ligne de passage de point mort P tel qu'illustré sur la figure 7. Durant cette étape, le ressort de manoeuvre 16 maintient dans la position fermée les contacts, ceci grâce à l'effort exercé dudit ressort et à la forme concentrique de la came 2, laquelle en position fermée, ne transmet aucun couple d'ouverture.
Au-delà de la position de passage du point mort, le système est entraîné de manière autonome sous l'effet du ressort de manoeuvre 16. Ceci entraîne le déplacement de la manivelle de compression 14 dans le sens horaire, laquelle dans son mouvement prend en charge l'axe d'entraînement Y de la manivelle de manoeuvre 11 par l'intermédiaire de la butée 14c dite butée d'entraînement ouverture de la manoeuvre de compression 14. Au contact de la butée d'entraînement ouverture 14c avec l'axe d'entraînement Y de la manivelle de manoeuvre 11, le couple exercé par l'action F2 du ressort de manoeuvre 16 sur la manivelle de manoeuvre 11 est supérieur au couple exercé par l'action F1 de la bielle de liaison 12. Ce différentiel de couple entraîne la rotation de la manivelle de manoeuvre 11 et de l'arbre à came 1 par l'intermédiaire de la bielle de liaison 12, et en conséquence l'ouverture des contacts.
L'entraînement du sous-ensemble pression de contact se termine à l'arrêt de l'arbre à came par une butée du galet dans la lumière de la came.
Les principaux avantages procurés par l'invention sont les suivants :
Ce principe permet de maintenir les contacts en position pendant la manoeuvre de changement d'état. Un seul ressort est utilisé pour l'ouverture et la fermeture. L'énergie délivrée à la fermeture est le double de celle délivrée à l'ouverture, ce qui s'adapte parfaitement au besoin de fonctionnement d'une ampoule à vide. L'utilisation de l'effort des deux extrémités du ressort permet l'utilisation d'un ressort de plus faible effort. L'évolution des bras de levier lors de la fermeture des contacts permet de compenser la diminution de l'effort du ressort. Il en découle un effort retransmis sur l'arbre à came qui reste constant sur une grande course. Cela favorise la distribution de l'énergie vers les contacts mobiles par l'intermédiaire de la came.
Ce dispositif permet d'obtenir un choc lors de l'ouverture qui permet de briser éventuellement les collages ou les soudures et qui permet d'obtenir une séparation franche des contacts électriques. Ce choc est réalisé par le fait qu'à l'ouverture, on a une phase de décompression des ressorts de pression de contact. Pendant cette phase, tout le mécanisme se met en mouvement alors que la pièce 7 et le contact mobile ne bougent pas. En fin de décompression du ressort de pression 10, l'extrémité 8b de la cage 8 prend en charge brutalement la tige 7 et le contact mobile, en générant un choc.
On notera que ce mécanisme est manoeuvrable à distance par motorisation, la manoeuvre pouvant être réalisée par un seul mouvement ou par pompage si cela est nécessaire.
Ce principe est principalement bien adapté à l'entraînement de contacts nécessitant des efforts en fin de course importants.
Ce dispositif pourrait utiliser, à la place du système à came pour la transmission du mouvement vers les contacts mobiles, un système d'embiellage qui aurait comme caractéristique de retransmettre de très faibles efforts pour la mise en pression des contacts électriques.
L'invention est applicable à tous les dispositifs réalisant des fonctions électriques avec un pouvoir de fermeture et d'ouverture, notamment de type interrupteur et nécessitant une manoeuvre de type tumbler.
Le principe de l'invention peut également être utilisé avantageusement dans des appareils réalisant les fonctions sectionneur de mise à la terre comportant un pouvoir de fermeture.
Il peut également être utilisé pour réaliser les fonctions disjoncteurs avec mise en place d'un accrochage pour réaliser le déclenchement.On the figure 1 , a control device D is seen of the contacts of an electrical switching device such as a switch or a disconnector, according to the invention. This device comprises a first set illustrated on the figure 2 said assembly comprising a camshaft 1 hingedly connected to a frame, said shaft being rotatably connected to a cam 2, and a guide rod 3 also hingedly connected to said frame by a said first one 3a, its ends. These parts are connected together by a roller 4 slidably mounted in an arcuate groove 5 of the cam 2 and having an axis 6 secured to a rod 7. This rod 7 is slidably mounted inside a cage 8 and secured by its opposite end to that connected to the roller 4, the movable contact (not shown) of the device. This cage 8 also comprises a housing 9 intended to receive a spring 10, said spring 10 being supported by one of its ends 10a on an inner face 8a of the cage and by its opposite end 10b on a piece 10c resting on another face 8b of the cage so as to contribute to ensuring the contact pressure between the movable contact and the fixed contact. These parts are connected together so that a rotation of the camshaft causes a vertical displacement of the axis 6 of the roller 4 and as a result of the movable contact.
This device also comprises, as illustrated in the other figures, an operating crank 11 pivotally connected relative to the frame. This maneuvering crank 11 is connected in an articulated manner, by one end 11a, to one said first 12a of the ends 12a, 12b of a connecting rod 12, said connecting rod 12 being at its end said second 12b opposite the first, hingedly connected to a drive crank 13 of the aforesaid cam shaft 1. This device D also comprises a compression crank 14 connected in an articulated manner to the frame, about the same axis X that the axis around which is connected to the frame the operating crank 11. This compression crank 14 has one end 14a hingedly connected to an end portion 15a of a spring guide rod 15. This guide rod 15 comprises a set of rods for compressing and guiding an operating spring 16 interposed between its two parts ends 15a, 15b. This compression crank 14 includes an opening driving abutment 14c and a closing driving abutment 14b, as will be explained later.
This device also comprises an operating lever L (illustrated on the figure 4 ) rotatably mounted relative to the frame and adapted to drive the aforesaid compression crank 14.
This device is completed by a holding latch 17 of a drive shaft Y of the operating crank 11, said axis 11 also being the axis of articulation of the connecting rod to the connecting rod. For this purpose, the lock comprises a notch 20 cooperating with said axis, and is biased in the locking position by a tension spring 18 connected by one 18a of its ends to the frame, and its opposite end 18b to the lock. Unlocking of the Y axis will be achieved by means of a lifting finger 19 provided on the compression crank 14.
The operation of the device will be described in the following with reference to the figures.
On the figure 3 , the device is in an open position. During a closing maneuver, as shown on the figure 4 , the lever L is driven downward counterclockwise until the compression crank 14 and the spring rod 15 pass through a dead center line P. During this step, the latch 17 maintains the axis drive Y of the operating crank 11 in a position called opening of the contacts.
Beyond the neutral position, the system is driven autonomously under the effect of the operating spring 16, as shown in FIG. figure 5 .
During this rotation of the compression crank 14 under the effect of the operating spring 16, the lifting finger 19 provided on said crank 14, drives the latch 17 in the clockwise direction so that the drive shaft 11a the operating crank 11 is released from the notch 20 provided in the holding latch 17 in which it was retained. At the same time, the closing abutment 14b of the compression crank 14 has come into contact with the drive shaft Y of the operating crank 11. This results in a drive of the operating crank 11 by the crank compression 14, which causes the movement of the connecting rod 12. This movement of the connecting rod 12 drives the drive crank 13 in the counterclockwise direction, under the effect of the force F1 exerted by the connecting rod 12 and the operating crank 11 ( fig.5 ) and under the action F2 of the operating spring 16. This results in a rotation of the cam shaft 1 in the counterclockwise direction, which causes the subset moving contact pressure until the pressure of the fixed and movable contacts, then the stop of the movement of the camshaft 1 by the abutment of the roller 4 inside the groove 5 of the cam 2 ( fig.6 ).
The closing of the contacts is maintained thanks to the effect of the operating spring 16. The force transmitted on the camshaft is provided for a part, by the force exerted directly by the lower end 16a of the operating spring 16 , and for another part, by the force exerted by the upper end 16b of the spring 16 retransmitted by the connecting rod 12 to the movable contact with the operating crank 11 and the compression crank 14. the forces exerted by the two ends of the spring, this thanks to the position of the spring interposed between two moving parts of the mechanism during the maneuver.
The opening maneuver is performed according to the following steps:
From the closed position illustrated on the figure 6 the lever L is driven upward clockwise until the compression crank 14 and the spring guide rod 15 pass through the dead center line P as illustrated in FIG. figure 7 . During this step, the operating spring 16 maintains in the closed position the contacts, this thanks to the exerted force of said spring and the concentric shape of the cam 2, which in the closed position, transmits any opening torque.
Beyond the neutral position of the passage, the system is driven autonomously under the effect of the operating spring 16. This causes the displacement of the compression crank 14 in the clockwise direction, which in its movement takes the drive shaft Y of the operating crank 11 is loaded via the abutment 14c, the so-called drive abutment, opening of the compression maneuver 14. In contact with the drive abutment 14c with the drive shaft Y drive of the operating crank 11, the torque exerted by the action F2 of the operating spring 16 on the operating crank 11 is greater than the torque exerted by the action F1 of the connecting rod 12. This torque differential causes rotation of the operating crank 11 and of the cam shaft 1 via the connecting rod 12, and consequently the opening of the contacts.
The drive of the contact pressure subassembly terminates when the camshaft stops by a stop of the roller in the lumen of the cam.
The main advantages provided by the invention are as follows:
This principle keeps the contacts in position during the change of state maneuver. Only one spring is used for opening and closing. The energy delivered at the closing is twice that delivered at the opening, which adapts perfectly to the need for operation of a vacuum bulb. The use of the force of the two ends of the spring allows the use of a spring of lower effort. The evolution of the lever arms during the closure of the contacts makes it possible to compensate for the decrease in the spring force. This results in an effort retransmitted on the camshaft which remains constant over a large race. This promotes the distribution of energy to the moving contacts via the cam.
This device makes it possible to obtain a shock during the opening which makes it possible to break the gluing or welding and which makes it possible to obtain a clean separation of the electrical contacts. This shock is achieved by the fact that at the opening, there is a decompression phase of the contact pressure springs. During this phase, the whole mechanism starts moving while the part 7 and the moving contact do not move. At the end of decompression of the pressure spring 10, the end 8b of the cage 8 brutally supports the rod 7 and the movable contact, generating a shock.
Note that this mechanism is remotely operable by motorization, the maneuver can be performed by a single movement or by pumping if necessary.
This principle is mainly well suited to the training of contacts requiring significant end-of-race efforts.
This device could use, instead of the cam system for the transmission of movement to the movable contacts, a linkage system which would have the characteristic of retransmitting very low forces for the pressurization of the electrical contacts.
The invention is applicable to all devices performing electrical functions with a power of closing and opening, in particular of the switch type and requiring a maneuver tumbler type.
The principle of the invention can also be used advantageously in apparatus performing the earthing switch functions having a closing power.
It can also be used to perform the functions of circuit breakers with implementation of a snap to perform the trip.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple.Of course, the invention is not limited to the embodiment described and illustrated which has been given by way of example.
