Abstract

The rapid closure mechanism has a contact carrier (5) with spring return with a contact block mechanism (6). An interposition arm (9) is guided without forcing between the contacts and contained by the wall sides and protruding rib sections, and the movement energy stored in a spring (7). The interposition arm is moved by a handle (1), and in the blocking position the energy is rapidly stored when the moving contact terminates its course. The energy is rapidly restored by the spring.

Description

La présente invention concerne un appareil électrique de commutation du type disjoncteur, c'est-à-dire comportant essentiellement au moins un contact mobile destiné à coopérer avec au moins un contact fixe afin de permettre une commutation protégée sur une ligne d'un circuit électrique. Plus précisément, l'invention a directement trait à la possibilité pour cet appareillage d'établir un contact brusque à la fermeture du circuit, et de mettre en oeuvre à l'ouverture du circuit la fonction dénommée sectionnement en cas de soudure des contacts.The present invention relates to an electrical appliance for circuit breaker type switching, i.e. comprising essentially at least one movable contact intended to cooperate with at minus a fixed contact to allow protected switching on a line of an electrical circuit. More specifically, the invention has directly relates to the possibility for this equipment to establish contact abrupt at the closing of the circuit, and to implement at the opening of the circuit the function called sectioning in case of welding of contact.

La fermeture brusque se définit notamment par l'indépendance entre l'énergie appliquée à une manette de commande de l'appareil et celle qui est communiquée au contact mobile lorsqu'il effectue la dernière portion de son parcours visant à l'amener contre le contact fixe. L'un des principes qui est à la base des systèmes à fermeture brusque consiste à interposer un élément entre les contacts, contre lequel le contact mobile vient dans un premier temps buter au cours de son mouvement de rotation consécutif à l'entraínement de la manette de commande, et à escamoter ensuite ledit élément lorsque la manette est dans la partie terminale de sa course de fermeture desdits contacts.The sudden closure is defined in particular by the independence between the energy applied to a device control handle and that which is communicated to the mobile contact when it makes the last portion of its course aimed at bringing it against the fixed contact. One of the principles that underpin snap closure systems are to interpose an element between the contacts, against which the contact mobile first comes up against its movement of rotation following the drive of the control lever, and then retract said element when the lever is in the part end of its closing stroke of said contacts.

Dans les dispositifs de protection auxquels s'applique l'invention, le mouvement communiqué à la manette de commande est transmis au contact mobile via un porte-contact sur lequel le contact mobile est monté élastiquement au moyen d'un ressort de liaison.In the protective devices to which the invention applies, the movement communicated to the joystick is transmitted to the mobile contact via a contact holder on which the mobile contact is resiliently mounted by means of a connecting spring.

Pendant la phase de rétention du contact mobile par l'élément interposé, la manette et le porte-contact poursuivent leur rotation, aboutissant à comprimer ledit ressort de liaison. L'énergie emmagasinée est brutalement restituée lorsque l'élément interposé s'efface, permettant une fermeture brusque des contacts.During the retention phase of the mobile contact by the element interposed, the lever and the contact carrier continue their rotation, resulting in compressing said connecting spring. The energy stored is suddenly restored when the interposed element disappears, allowing a Abrupt closing of the contacts.

L'un des paramètres essentiels des systèmes à fermeture brusque est la hauteur de chute, qui doit être suffisante pour empêcher la création d'un arc électrique, mais pas trop importante pour éviter tout rebond lorsque le contact mobile est relâché, et pour que la compression du ressort ne soit pas trop forte.One of the key parameters of snap-close systems is the fall height, which must be sufficient to prevent the creation of an arc electric, but not too important to avoid any rebound when the contact mobile is released, and so that the compression of the spring is not too strong.

Le moment de la restitution de l'énergie, c'est-à-dire le moment du "lâcher" du contact mobile, est également essentiel : il est nécessaire que l'effort électrodynamique qui s'applique au moment de la fermeture des contacts, dans le sens d'un écartement de ces derniers, soit équilibré par la force du ressort, pour garantir que l'effort de pression soit suffisant à la fermeture. Cette pression doit de plus s'appliquer le plus uniformément possible sur toute la surface de contact, pour éviter tout risque de soudure si la zone de contact s'agrandit trop progressivement, et demeure dès lors restreinte pendant trop longtemps.The moment of energy restitution, that is to say the moment of "letting go" of the mobile contact, is also essential: it is necessary that the effort electrodynamics which applies when the contacts are closed, in the direction of a spacing of the latter, is balanced by the force of the spring, to ensure that the pressure force is sufficient on closing. This pressure must more apply as uniformly as possible over the entire contact surface, to avoid any risk of welding if the contact area becomes too gradually enlarged, and therefore remains restricted for too long.

En résumé, les systèmes à fermeture brusque doivent être conçus pour faire chuter le contact mobile sur le contact fixe d'une certaine hauteur à un certain moment.In summary, snap-close systems must be designed to drop the moving contact on the fixed contact from a certain height to a certain moment.

Lorsque l'on utilise un élément s'interposant entre lesdits contacts, la hauteur de chute est garantie. Pour bien maítriser le moment du "lâcher", il est alors préférable de prendre l'information sur une pièce qui a une amplitude de déplacement suffisante. La manette répond bien à cette exigence, et permet un bon contrôle du moment adéquat pour escamoter l'élément interposé.When using an element interposed between said contacts, the height of fall is guaranteed. To master the moment of "letting go", it is therefore preferable to take the information on a part which has an amplitude of displacement sufficient. The controller responds well to this requirement, and allows good control of the adequate time to retract the interposed element.

Un dispositif dans lequel la manette agit directement sur un élément d'interposition entre le contact mobile et le contact fixe a été décrit dans le brevet allemand DE 40 16 364, qui divulgue une solution dans laquelle le tambour de la manette de commande comporte une fente curviligne, située au voisinage de la périphérie dudit tambour, permettant une liaison mécanique avec l'extrémité d'une tige. Cette liaison présente deux degrés de liberté, à savoir un déplacement dans la fente et un pivotement de l'extrémité de la tige en tout lieu dans ladite fente.A device in which the lever acts directly on an element between the moving contact and the fixed contact has been described in the patent German DE 40 16 364, which discloses a solution in which the drum of the control lever has a curvilinear slot, located near the periphery of said drum, allowing a mechanical connection with the end of a rod. This connection presents two degrees of freedom, namely a displacement in the slot and a pivoting of the end of the rod at any place in said slot.

L'autre extrémité de ladite tige repose sur un sabot surplombant le contact fixe, de manière à pouvoir stopper le mouvement du contact mobile lorsque celui-ci arrive à proximité du contact fixe en réponse à un déplacement rotatif de la manette de commande.The other end of said rod rests on a shoe overhanging the fixed contact, so as to be able to stop the movement of the movable contact when the latter arrives near the fixed contact in response to a rotary movement of the control lever.

Lorsqu'on arrive dans la portion finale de la course de ladite manette en vue de la fermeture des contacts, le contact mobile arrive contre l'extrémité libre de ladite tige, et comprime un ressort le reliant à une platine entraínée par la manette. La longueur de la tige d'interposition et celle de la fente du tambour de la manette de commande sont calculées de telle sorte que, à un point ultérieur de la course de la manette, la tige d'interposition est entraínée par la manette, libérant brutalement le contact mobile.When we arrive in the final portion of the race of said lever in order to closing of the contacts, the movable contact arrives against the free end of said rod, and compresses a spring connecting it to a plate driven by the lever. The length of the interposition rod and that of the drum slot of the joystick command are calculated so that at a later point in the course of the lever, the interposition rod is driven by the lever, suddenly releasing the mobile contact.

L'entraínement de ladite tige survient lorsque son extrémité reliée au tambour de la manette arrive en bout de la fente curviligne.The training of said rod occurs when its end connected to the drum of the lever arrives at the end of the curvilinear slot.

Dans ce système, des moyens de rappel sont fixés d'une part à la tige d'interposition et d'autre part au bâti de l'appareil, permettant le retour de la tige d'interposition en position de blocage du contact mobile lorsque la manette est actionnée dans la direction d'ouverture des contacts.In this system, return means are fixed on the one hand to the rod interposition and secondly to the frame of the device, allowing the return of the rod interposition in the locking position of the movable contact when the lever is operated in the opening direction of the contacts.

Ce système, divulguant le principe général théorique de la liaison directe de l'élément d'interposition avec la manette de commande, souffre cependant d'un certain nombre d'inconvénients pratiques, lorsqu'il doit être mis en oeuvre dans un appareil électrique du type disjoncteur. En premier lieu, le montage de ces appareils doit - pour d'évidentes raisons économiques - être simplifié au maximum, afin notamment de pouvoir être automatisé. En l'occurrence, l'installation de moyens de rappel du type ressort entre le bâti et l'élément d'interposition, voire le montage de l'extrémité de la tige dans le tambour de la manette, nécessitent des interventions manuelles qui rendent ce système théoriquement intéressant, mais guère applicable en phase d'industrialisation sans obérer sensiblement les coûts de production.This system, disclosing the general theoretical principle of the direct connection of the interposition element with the control handle, however suffers from a a certain number of practical disadvantages, when it has to be implemented in a circuit breaker type electrical appliance. First, the mounting of these devices must - for obvious economic reasons - be simplified to maximum, in particular in order to be able to be automated. In this case, the installation spring-type return means between the frame and the interposing element, see the mounting of the end of the rod in the handle drum, require manual intervention which makes this system theoretically interesting, but hardly applicable during the industrialization phase without obstructing production costs significantly.

La présente invention s'affranchit de ces inconvénients, et présente un système dans lequel un bras d'interposition entre le contact mobile et le contact fixe est très simplement disposé après et sur les composants constituant l'appareil électrique dans lequel il est implanté, puis guidé grâce à la configuration particulière donnée à ces composants et/ou au boítier de l'appareil.The present invention overcomes these drawbacks, and presents a system in which an interposing arm between the movable contact and the fixed contact is very simply placed after and on the components making up the electrical appliance in which it is installed, then guided thanks to the particular configuration given to these components and / or the housing of the device.

En terme d'automatisation, donc d'industrialisation, l'ajout de cette fonction ne pose par conséquent aucun problème technique, et les incidences économiques sont mineures à la fabrication.In terms of automation, therefore industrialization, the addition of this function does not therefore poses no technical problems, and the economic implications are minor to manufacturing.

De plus, le dispositif objet de l'invention permet de réaliser la fonction de sectionnement, ce que ne permettait pas d'assurer le système du brevet allemand DE 40 16 364.In addition, the device which is the subject of the invention makes it possible to perform the function of sectioning, which the German patent system did not provide DE 40 16 364.

D'une manière générale, l'invention concerne un appareil électrique de commutation du type disjoncteur comportant au moins un contact mobile destiné à coopérer avec au moins un contact fixe par rapport au boítier, le contact mobile étant disposé sur un porte-contact actionné en rotation à l'aide d'une manette mobile entre deux positions stables correspondant respectivement à l'ouverture et à la fermeture des contacts, le contact mobile étant lui-même disposé à rotation sur ledit porte-contact, des moyens de rappel élastiques étant prévus entre eux pour solliciter le contact mobile dans la direction de fermeture des contacts. Un bras commandé par la manette est disposé pour s'interposer ente les contacts pendant une portion de la course finale de fermeture du contact mobile, le porte-contact pouvant continuer sa course alors que le contact mobile est bloqué, lesdits moyens de rappel emmagasinant alors de l'énergie. Le bras est ensuite escamoté, permettant au contact mobile de continuer sa course avec l'énergie restituée par lesdits moyens de rappel.In general, the invention relates to an electrical appliance for circuit breaker type switching comprising at least one movable contact intended for cooperate with at least one fixed contact relative to the housing, the movable contact being disposed on a contact carrier actuated in rotation by means of a handle movable between two stable positions corresponding respectively to the opening and when the contacts are closed, the movable contact itself being disposed in rotation on said contact carrier, elastic return means being provided between them to apply the movable contact in the closing direction of the contacts. An arm controlled by the lever is arranged to interpose between the contacts during a portion of the final stroke for closing the movable contact, the contact carrier can continue its race while the moving contact is blocked, said means of recall thus storing energy. The arm is then retracted, allowing the mobile contact to continue its course with energy returned by said recall means.

Selon une caractéristique essentielle à l'invention, ledit bras est conçu pour être guidé sans fixation, par simples contacts avec des parois, nervures et reliefs prévus et orientés à cet effet dans le boítier, le déplacement dudit bras, présentant une composante translative combinée à une composante rotative, étant assuré par l'action combinée du contact mobile, de la manette de commande et du poids du bras.According to a characteristic essential to the invention, said arm is designed to be guided without fixing, by simple contacts with walls, ribs and reliefs provided and oriented for this purpose in the housing, the movement of said arm, having a translative component combined with a rotary component, being provided by the combined action of the moving contact, the control lever and the weight of the arms.

En somme, une sorte de logement est réalisé après implantation de tous les composants de l'appareil, prévu pour pouvoir déposer le bras d'interposition entre des repères conçus soit directement dans le boítier, soit dans lesdits composants.In short, a kind of housing is created after all of the components of the device, designed to be able to remove the interposing arm between marks designed either directly in the case, or in said components.

Bien entendu, tous les éléments participant au guidage ont été conçus, notamment dimensionnellement, de manière à pouvoir assurer à la fois les fonctions de fermeture brusque et de sectionnement.Of course, all the elements involved in guiding have been designed, especially dimensionally, so as to be able to ensure both abrupt closing and sectioning functions.

Ainsi, ledit bras comporte une encoche latérale débouchant du côté de la manette de commande, laquelle comporte une première butée agissant sur l'une des extrémités du bras lorsqu'elle est en position stable d'ouverture des contacts, le bras étant alors dans sa position de blocage du contact mobile, et un doigt d'actionnement prévu pour coopérer avec les côtés transversaux de l'encoche, d'allure parallèle à ladite extrémité du bras, afin de l'entraíner selon un coulissement d'allure parallèle à son axe, sans empêcher sa rotation.Thus, said arm has a lateral notch opening on the side of the control lever, which has a first stop acting on one the ends of the arm when it is in the stable contact opening position, the arm then being in its position for blocking the movable contact, and a finger actuation provided to cooperate with the transverse sides of the notch, parallel to said end of the arm, in order to drive it in a sliding fashion parallel to its axis, without preventing its rotation.

Le logement précité, ainsi que la configuration géométrique des différents éléments, doit comme mentionné permettre un déplacement complexe du bras d'interposition, que l'on peut grosso modo diviser en une translation et une rotation d'amplitude limitée qui se produisent parfois simultanément.The aforementioned housing, as well as the geometric configuration of the different elements, must as mentioned allow a complex movement of the arm of interposition, which can roughly be divided into a translation and a rotation of limited amplitude which sometimes occur simultaneously.

Plus précisément, la butée et le doigt d'actionnement sont disposés à la périphérie d'un tambour rotatif formant avec un levier de manipulation la manette, au niveau d'un évidement pratiqué à l'extrémité axiale du tambour, et disposant d'un fond plat sur lequel prend appui le bras, la première butée étant un épaulement limitant cet évidement au voisinage dudit levier, le doigt d'actionnement étant un plot axial d'allure cylindrique placé dans l'évidement de telle sorte qu'il puisse s'introduire dans l'encoche du bras lors du déplacement de la manette de commande vers la position de fermeture des contacts, ladite encoche étant dimensionnée pour que ledit doigt d'actionnement puisse agir sur d'une part l'un desdits côtés transversaux de ladite encoche dans la portion de course finale de la manette pendant laquelle le contact mobile est bloqué, et d'autre part l'autre côté transversal pendant la course inverse de la manette, dans le sens de l'ouverture des contacts.More specifically, the stop and the actuating finger are arranged at the periphery of a rotary drum forming the handle with a manipulation lever, at a recess made at the axial end of the drum, and having a flat bottom on which the arm rests, the first stop being a shoulder limiting this recess in the vicinity of said lever, the finger actuator being an axial stud of cylindrical appearance placed in the recess of so that it can get into the notch of the arm when moving the control lever towards the closed position of the contacts, said notch being sized so that said actuating finger can act on the one hand one of said transverse sides of said notch in the final stroke portion the lever during which the movable contact is blocked, and on the other hand the other transverse side during the reverse stroke of the lever, in the direction of opening contacts.

La butée et le doigt d'actionnement de la manette interviennent essentiellement au titre du coulissement, c'est-à-dire du déplacement translatif, mais ils ne s'opposent pas à une rotation par ailleurs nécessitée par les fonctions à mettre en oeuvre, et permise par la localisation des autres butées / nervures.The stop and the actuating finger of the lever intervene essentially for sliding, i.e. translational displacement, but they do not not oppose a rotation otherwise required by the functions to be implemented work, and enabled by the location of the other stops / ribs.

Pour que l'interaction entre la manette et le bras d'interposition soit optimale, et qu'elle permette également de respecter certains jeux fonctionnels, la configuration de la manette est telle que de préférence, le doigt d'actionnement est excentré sur une excroissance dépassant radialement du tambour de la manette de commande.So that the interaction between the joystick and the interposing arm is optimal, and that it also allows certain functional games to be respected, the configuration of the handle is such that preferably the actuating finger is offset on a protrusion protruding radially from the drum of the joystick ordered.

De préférence, ce doigt est constitué de l'extrémité de la biellette reliant la manette au porte-contact, ce qui permet de tirer le meilleur parti de la structure des appareils existants, qui présentent cette configuration même lorsqu'ils sont dépourvus de mécanisme de fermeture brusque et de sectionnement.Preferably, this finger consists of the end of the link connecting the lever to the contact carrier, which makes the most of the structure of the existing devices, which have this configuration even when they are lacking an abrupt closing and cutting mechanism.

Lors de l'entraínement de la manette de commande dans le sens de la fermeture des contacts, le bras d'interposition, lorsqu'il est escamoté, est tracté vers la façade du produit, c'est-à-dire la paroi qui comporte la fenêtre dans laquelle se déplace la manette. Selon une possibilité, cette paroi sert de plus de butée à l'extrémité du bras qui lui est voisine, en fin de course de ladite manette lorsque les contacts sont fermés.When driving the joystick in the direction of the closing of the contacts, the interposing arm, when it is retracted, is pulled towards the front of the product, i.e. the wall which includes the window in which moves the joystick. According to one possibility, this wall serves more as a stop for the end of the arm which is adjacent to it, at the end of the travel of said lever when the contacts are closed.

L'autre extrémité du bras d'interposition, située à proximité de la zone de contact, présente un profil lui permettant d'un côté de bloquer le contact mobile, et de l'autre côté de s'adapter à un profil-came solidaire du boítier. Ce dernier lui permet d'une part de rester d'abord en butée avant de s'escamoter par rotation sous l'action du contact mobile après avoir subi simultanément un coulissement en direction de la manette de commande, et d'autre part de réaliser un blocage lorsque le bras coulisse dans l'autre sens, uniquement en cas de soudure des contacts, pour assurer la fonction de sectionnement.The other end of the interposition arm, located near the area of contact, has a profile allowing it on one side to block the mobile contact, and on the other side to adapt to a cam profile integral with the housing. The latter allows on the one hand to remain first in abutment before retracting by rotation under the action of the movable contact after having simultaneously undergone a sliding in direction of the joystick, and secondly to achieve a blocking when the arm slides in the other direction, only if the contacts, to ensure the isolation function.

Le profil-came est donc dessiné pour interagir avec l'extrémité libre du bras dans les deux sens de déplacement de la manette de commande, selon la position relative des contacts fixe et mobile, et pour réaliser des guidages / blocages du bras correspondant aux fonctions à réaliser.The cam profile is therefore designed to interact with the free end of the arm in both directions of movement of the joystick, depending on the relative position of the fixed and mobile contacts, and to produce guides / arm blockages corresponding to the functions to be performed.

Ainsi, dans la direction de fermeture des contacts, la fonction de fermeture brusque impose comme expliqué ci-dessus un maintien à distance des contacts, suivi d'un lâcher brusque. La fonction de sectionnement impose le blocage du bras dans une position empêchant le retour de la manette en position correspondant à l'ouverture des contacts, mais uniquement si les contacts sont soudés. S'ils ne le sont pas, le profil-came devra guider le bras vers sa position initiale, contacts ouverts.Thus, in the closing direction of the contacts, the closing function abrupt requires, as explained above, keeping contacts at a distance, followed by an abrupt release. The sectioning function requires the arm to be locked in a position preventing the lever from returning to the position corresponding to opening of the contacts, but only if the contacts are welded. If they don't are not, the cam profile should guide the arm to its initial position, contacts open.

Plus précisément, le profil-came présente une forme à deux marches d'escalier permettant au bras d'adopter deux positions distinctes selon son état de coulissement, une position de blocage du contact mobile à distance du contact fixe, et une position escamotée permettant au contact électrique de s'établir brusquement à la fin du déplacement de la manette aboutissant à la fermeture des contacts. La contremarche sert quant à elle au blocage du bras, stoppant à son tour la rotation de la manette lors du déplacement inverse visant à l'ouverture des contacts.More precisely, the cam profile has a shape with two stair treads allowing the arm to adopt two distinct positions according to its state of sliding, a position for blocking the movable contact at a distance from the fixed contact, and a retracted position allowing the electrical contact to be established suddenly at the end of the movement of the joystick leading to the closing of the contact. The riser is used for blocking the arm, in turn stopping the rotation of the lever during the reverse movement aimed at opening the contact.

L'orientation relative sensiblement perpendiculaire des marches et de la contremarche, et leur orientation par rapport au boítier et au bras, s'expliquent notamment par le fait que les marches agissent par rapport à un déplacement d'ordre rotatif de l'extrémité libre du bras d'interposition, alors que la contremarche agit à l'encontre d'un mouvement de coulissement de ce dernier.The substantially perpendicular relative orientation of the steps and the riser, and their orientation relative to the housing and the arm, are explained in particular by the fact that the steps act in relation to a displacement of the free end of the interposing arm, while the riser acts against a sliding movement of the latter.

Le profil d'extrémité du bras sur lequel le contact mobile arrive en appui est orienté sensiblement parallèlement à l'orientation du contact mobile au moment où celui-ci arrive contre le bras au cours du déplacement de la manette en vue de fermer les contacts.The end profile of the arm on which the movable contact comes into contact is oriented substantially parallel to the orientation of the movable contact when this arrives against the arm during the movement of the joystick in order to close the contacts.

Le contact mobile peut dès lors reposer suivant un appui plan, stable, contre le bras lorsqu'il est en position d'interposition. Pour assurer la stabilité de l'ensemble, il convient cependant que la liaison opposée bras / profil-came soit dotée du même niveau de stabilité.The movable contact can therefore rest according to a flat, stable support against the arm when in the interposition position. To ensure the stability of the whole, however, the opposite link arm / profile-cam should have the same level of stability.

Le profil d'extrémité du bras destiné à entrer en contact avec le profil-came comporte à cet effet un coin dont les deux faces sont sensiblement perpendiculaires et orientées de telle sorte qu'elles prennent un appui également plan sur les marches et la contremarche dans les différentes positions de fonctionnement, permettant respectivement le blocage en rotation, le guidage de l'escamotage du bras, et son blocage en translation.The end profile of the arm intended to come into contact with the cam profile has for this purpose a corner whose two faces are substantially perpendicular and oriented so that they also take support plan on the steps and riser in the different positions of operation, respectively allowing the rotation blocking, the guiding of the retraction of the arm, and its locking in translation.

La face du coin qui est sensiblement parallèle à l'axe du bras agit dans le sens de la rotation, c'est-à-dire pour la fonction de fermeture brusque, alors que la face qui est perpendiculaire audit axe agit axialement, c'est-à-dire plutôt pour la fonction de sectionnement.The face of the corner which is substantially parallel to the axis of the arm acts in the direction of rotation, that is to say for the function of sudden closing, while the face which is perpendicular to said axis acts axially, that is to say rather for the function sectioning.

Il est également à noter que cette dernière face, du fait de son orientation et de celle de son appui, légèrement inclinées par rapport à la perpendiculaire à la force de poussée axiale, conduit à la création d'une composante de réaction qui contribue à la force d'arrachage des contacts.It should also be noted that this last side, due to its orientation and that of its support, slightly inclined with respect to the perpendicular to the force of axial thrust, leads to the creation of a reaction component which contributes to the breakout force of the contacts.

De plus, ladite face du coin destinée à venir en appui sur les marches et le profil destiné à venir au contact du contact mobile sont sensiblement parallèles, de manière à garantir une distance entre contacts constante.In addition, said face of the corner intended to come to bear on the steps and the profile intended to come into contact with the movable contact are substantially parallel, of so as to guarantee a constant distance between contacts.

Les appareils électriques concernés par l'invention comportent un boítier doté d'une première coque dans laquelle sont disposés les composants dudit appareil, et d'un couvercle de fermeture qui comporte en l'occurrence des nervures formant butées et guidant le mouvement du bras, disposées principalement de manière à agir sur le côté du bras d'interposition opposé à la manette de commande lorsque le contact mobile s'écarte du contact fixe.The electrical devices concerned by the invention include a box provided a first shell in which the components of said device are arranged, and a closure cover which in this case has ribs forming stops and guiding the movement of the arm, mainly arranged so as to act on the side of the interposing arm opposite the control lever when the movable contact deviates from the fixed contact.

Plus précisément, lesdites nervures sont disposées au niveau des extrémités du bras et délimitent avec le profil-came de la coque d'une part, et la manette de commande d'autre part, un couloir plus large que ledit bras, dans lequel celui-ci peut coulisser et subir une rotation de faible amplitude.More specifically, said ribs are arranged at the ends of the arm and delimit with the cam profile of the shell on the one hand, and the lever of controls on the other hand, a corridor wider than said arm, in which the latter can slide and undergo a small amplitude rotation.

Cette configuration, ainsi que l'orientation des marches d'escalier et du coin d'extrémité du bras d'interposition sont telles que lorsque le produit est fixé dans un tableau de distribution électrique, en général sur un rail de guidage standardisé, la manette et le profil-came se situent au-dessus du bras d'interposition, et les nervures précitées en dessous.This configuration, as well as the orientation of the stair steps and the corner ends of the interposing arm are such that when the product is fixed in an electrical distribution board, generally on a standardized guide rail, the lever and the cam profile are located above the interposition arm, and the ribs mentioned above.

De la sorte, lorsque le contact mobile s'écarte du contact fixe, le bras a tendance à retomber vers le bas sous l'effet de son poids, et ne peut ainsi plus entrer en collision avec la contremarche lorsque le doigt cylindrique de la manette le repousse avant de se dégager de l'encoche du bras d'interposition.In this way, when the movable contact departs from the fixed contact, the arm tends to to fall back down due to its weight, and can no longer enter collision with the riser when the cylindrical finger of the joystick grows back before releasing itself from the notch of the interposing arm.

En référence à la figure 1, l'appareil électrique de l'invention comporte un boítier externe composé d'une coque (B) dans laquelle sont disposés les composants constitutifs dudit appareil, cette coque étant fermée par un couvercle (C) (non représenté, voir figures 2 à 8), la coque (B) et le couvercle (C) formant le boítier présentant en l'occurrence un volume modulaire tel que généralement conféré aux appareils électriques selon l'invention. Referring to Figure 1, the electrical device of the invention comprises a housing external composed of a shell (B) in which the components are arranged constituting said device, this shell being closed by a cover (C) (not shown, see Figures 2 to 8), the shell (B) and the cover (C) forming the housing in this case having a modular volume as generally conferred on electrical devices according to the invention.

Pour la description de l'invention, il n'est pas nécessaire de décrire en détail tous les composants d'un disjoncteur classique, la plupart ne participant pas directement à la mise en oeuvre de l'invention. Pour simplifier la description, seuls les éléments utilisés seront décrits.For the description of the invention, it is not necessary to describe in detail all components of a conventional circuit breaker, most of which do not directly participate to the implementation of the invention. To simplify the description, only the elements used will be described.

Ainsi, ces appareils sont dotés d'une manette de commande (1), classiquement constituée d'un levier (2) s'étendant radialement à partir d'un tambour (3), monté rotatif par rapport au boítier.Thus, these devices are equipped with a control lever (1), conventionally consisting of a lever (2) extending radially from a drum (3), mounted rotatable relative to the housing.

La manette (1) actionne un mécanisme du type genouillère comportant notamment une biellette (4) dont l'extrémité distante de ladite manette (1) coopère avec un assemblage rotatif comprenant principalement un porte-contact (5) sur lequel est monté le contact mobile (6), selon une liaison à rotation contrôlée par un ressort de torsion (7).The lever (1) actuates a knee-type mechanism comprising in particular a link (4) whose remote end of said lever (1) cooperates with a rotary assembly mainly comprising a contact carrier (5) on which is mounted the movable contact (6), in a rotation connection controlled by a torsion spring (7).

Lors de la rotation de la manette (1) par manipulation du levier (2) vers la gauche de la figure, la genouillère entraíne le porte-contact (5) en rotation inverse de telle sorte que le contact mobile (6) se rapproche progressivement du contact fixe (8). A l'inverse, lorsque la manette (1) est entraínée en sens opposé, le mécanisme de genouillère entraíne le porte-contact (5), ainsi que le contact mobile (6), de manière à l'écarter du contact fixe (8).When the lever (1) is rotated by manipulating the lever (2) towards the left of the figure, the knee lever drives the contact carrier (5) in reverse rotation so that the movable contact (6) gradually approaches the contact fixed (8). Conversely, when the lever (1) is driven in the opposite direction, the toggle mechanism drives the contact carrier (5), as well as the movable contact (6), so as to move it away from the fixed contact (8).

Le porte-contact (5) coopère dans ce type de dispositif avec d'autres éléments formant une serrure mécanique de disjonction, qui sont actionnés lors de courts-circuits ou d'augmentations importantes du courant, par des dispositifs respectivement magnétiques et thermiques classiques, qui ne font cependant pas l'objet de l'invention et ne sont par conséquent pas décrits.The contact carrier (5) cooperates in this type of device with other elements forming a mechanical cut-out lock, which are actuated during short circuits or significant increases in current, by devices respectively magnetic and conventional thermal, which however do not the subject of the invention and are therefore not described.

La figure 1 fait également apparaítre un bras (9) disposé dans l'espace situé au-dessus de la zone des contacts, sensiblement entre lesdits contacts mobile (6) et fixe (8).Figure 1 also shows an arm (9) disposed in the space above of the contact area, substantially between said movable contacts (6) and fixed (8).

La figure 2 montre ces mêmes éléments, exactement dans la même configuration, un couvercle (C) figuré en transparence ayant été appliqué contre la coque (B). Dans la position d'ouverture des contacts, dans laquelle le levier (2) de la manette (1) est en position stable, orienté vers la droite du dessin, le bras d'interposition (9) est lui-même au repos dans une position stable, en appui contre un certain nombre de butées. Certaines des ces butées (10, 11) correspondent à des nervures / reliefs du couvercle, et apparaissent en trait gras. Elles sont localisées sur la droite du bras d'interposition (9), les zones d'appui sur chacun des éléments étant de manière générale figurées en trait hachuré. Figure 2 shows these same elements, exactly in the same configuration, a cover (C) shown in transparency having been applied against the shell (B). In the open position of the contacts, in which the lever (2) of the lever (1) is in a stable position, oriented to the right of the drawing, the arm interposition (9) is itself at rest in a stable position, pressing against a number of stops. Some of these stops (10, 11) correspond to ribs / reliefs on the cover, and appear in bold lines. They are located on the right of the interposing arm (9), the support zones on each of the elements generally being shown in hatched lines.

Une autre butée (12) est constituée dans le tambour (3) de la manette (1), à partir d'un évidement (13) pratiqué dans une partie du pourtour dudit tambour (3), comme cela apparaít notamment clairement en figure 11. Cet évidement (13) sert de plate-forme d'appui à l'une des extrémités du bras d'interposition (9), qui y repose de la même manière qu'il repose à son autre extrémité sur des reliefs et/ou composants de la coque (B). A proximité de la manette (1), cet évidement (13) s'achève par un épaulement (12) formant la butée précitée.Another stop (12) is formed in the drum (3) of the handle (1), from a recess (13) formed in a part of the periphery of said drum (3), as shown in particular clearly in Figure 11. This recess (13) serves support platform at one end of the interposing arm (9), which rests in the same way as it rests at its other end on reliefs and / or hull components (B). Near the lever (1), this recess (13) ends with a shoulder (12) forming the abovementioned stop.

L'autre bout du bras d'interposition (9) est calé dans un relief de forme adéquate formant la butée (11, 27) disposée dans le couvercle (C) du boítier.The other end of the interposing arm (9) is wedged in a relief of suitable shape forming the stop (11, 27) disposed in the cover (C) of the housing.

Compte tenu que l'appareil électrique, lorsqu'il est monté, est positionné de sorte que la façade que traverse la manette est verticale, ledit bras d'interposition (9) repose en fait en partie grâce à son poids sur les rainures (10) et (11) du couvercle.Given that the electrical appliance, when mounted, is positioned so that the facade through which the lever passes is vertical, said interposing arm (9) actually rests in part thanks to its weight on the grooves (10) and (11) of the lid.

La figure 3 montre les mêmes éléments, la manette (1) ayant en l'espèce démarré son mouvement de rotation en vue de la fermeture des contacts (6, 8). Dans ce cas, une butée ou doigt d'actionnement (14), situé sur une excroissance excentrée à la fois du tambour (3) et de l'évidement (13), entame également sa rotation, et débute son insertion dans une encoche (16) pratiquée dans le bras (9). En même temps, le mécanisme à genouillère entraíne le contact mobile (6) en rotation inverse, de manière à le rapprocher du contact fixe (8). La butée (12) limitant l'évidement (13) commence à s'écarter de l'extrémité (17) du bras d'interposition (9).Figure 3 shows the same elements, the handle (1) having in this case started its rotational movement with a view to closing the contacts (6, 8). In this case, an actuating stop or finger (14), located on a projection eccentric both of the drum (3) and the recess (13), also begins its rotation, and begins its insertion into a notch (16) formed in the arm (9). At the same time, the toggle mechanism drives the movable contact (6) in reverse rotation, so as to bring it closer to the fixed contact (8). The stop (12) limiting the recess (13) begins to move away from the end (17) of the arm interposition (9).

En poursuivant le mouvement, comme cela est montré par exemple en figure 4, le doigt d'actionnement (14) entre franchement dans l'encoche (16), au moment où le contact mobile (6) entre en contact avec le profil d'extrémité latéral (18) du bras d'interposition (9).Continuing the movement, as shown for example in the figure 4, the actuating finger (14) frankly enters the notch (16), at the time where the movable contact (6) comes into contact with the lateral end profile (18) of the interposing arm (9).

Ce dernier amorce une rotation de son extrémité inférieure, sous l'action du contact mobile (6), sa partie supérieure restant maintenue entre la nervure (10) du couvercle et la paroi interne (19) du tambour (3) de la manette (1).The latter begins a rotation of its lower end, under the action of the movable contact (6), its upper part remaining held between the rib (10) of the cover and the internal wall (19) of the drum (3) of the handle (1).

Dans la représentation de la figure 5, le contact mobile (6) est bloqué, au stade d'avancement de la manette (1) figuré, car le profil d'extrémité en coin (20) situé à l'opposé du profil (18) sur le bras (9) entre en contact avec la marche (21) d'un profil-came intégré à la coque (B) du boítier.In the representation of FIG. 5, the movable contact (6) is blocked, at the stage advancement of the lever (1) shown, because the corner end profile (20) located at the opposite of the profile (18) on the arm (9) comes into contact with the step (21) of a cam profile integrated into the shell (B) of the housing.

Le premier mouvement de rotation de l'extrémité contenant les profils (18) et (20) du bras d'interposition (9) est terminé, et les contacts respectivement fixe (8) et mobile (6) sont maintenus à une distance correspondant à la hauteur de chute. The first rotational movement of the end containing the profiles (18) and (20) of the interposing arm (9) is finished, and the contacts respectively fixed (8) and mobile (6) are kept at a distance corresponding to the height of fall.

L'entraínement de la manette (1) peut cependant continuer, comme cela apparaít en figure 6, impliquant une rotation correspondante du porte-contact (5), entraínant à son tour la compression du ressort (7) du fait de l'immobilité du contact mobile (6). Dans la position de la manette (1) montrée en figure 6, le doigt d'actionnement (14) arrive au contact du côté transversal supérieur (24) de l'encoche (16).The drive of the joystick (1) can however continue, like this appears in FIG. 6, implying a corresponding rotation of the contact carrier (5), in turn causing the compression of the spring (7) due to the immobility of the contact mobile (6). In the position of the handle (1) shown in Figure 6, the finger actuator (14) comes into contact with the upper transverse side (24) of the notch (16).

A mesure que le mouvement de pivotement de la manette (1) continue, comme montré en figure 7, le doigt d'actionnement (14) entraíne le bras d'interposition (9) vers le haut, suivant un coulissement guidé entre la nervure (10) du couvercle d'une part et, "diagonalement", la marche (21) au contact du profil en coin (20) d'autre part. il y a donc glissement dudit profil (20) sur la marche (21), et glissement du profil (18) le long du chant latéral du contact mobile (6). L'écartement entre ce dernier et le contact fixe n'est pour le moment pas encore modifié, du fait de l'orientation sensiblement parallèle des surfaces (10) et profils (20, 21, 18) précités.As the pivoting movement of the handle (1) continues, as shown in Figure 7, the actuating finger (14) drives the arm interposition (9) upwards, following a guided sliding between the rib (10) of the cover on the one hand and, "diagonally", the step (21) in contact with the profile corner (20) on the other hand. there is therefore sliding of said profile (20) on the step (21), and sliding of the profile (18) along the lateral edge of the movable contact (6). The gap between the latter and the fixed contact is not yet modified, because substantially parallel orientation of the surfaces (10) and profiles (20, 21, 18) supra.

Cette figure montre également l'existence d'un appui transversal entre un ressaut (25) situé à l'extrémité longitudinale du bras (9), et un prolongement (27) de la nervure (11) du couvercle (C) de surface sensiblement perpendiculaire aux profils (18, 20, 21, 10) précédemment cités.This figure also shows the existence of a transverse support between a projection (25) located at the longitudinal end of the arm (9), and an extension (27) of the rib (11) of the cover (C) of surface substantially perpendicular to the profiles (18, 20, 21, 10) previously cited.

Dans la dernière partie de la course de la manette (1), le bras (9) coulisse d'une distance suffisante pour permettre au profil d'extrémité en coin (20) d'être brutalement repoussé par le contact mobile (6) au contact de la marche (23), en glissant le long de la contremarche (22).In the last part of the lever stroke (1), the arm (9) slides sufficient distance to allow the corner end profile (20) to be suddenly repelled by the movable contact (6) in contact with the step (23), in sliding along the riser (22).

L'énergie restituée par le ressort (7) permet le relâchement du contact mobile et sa fermeture brusque contre le contact fixe (8), lorsque l'extrémité libre du bras (9) est repoussée vers la marche (23), pour une rotation d'amplitude limitée à la distance séparant les deux marches (21) et (23).The energy returned by the spring (7) allows the mobile contact to relax and its abrupt closure against the fixed contact (8), when the free end of the arm (9) is pushed back towards the step (23), for a rotation of amplitude limited to the distance separating the two steps (21) and (23).

En partie supérieure, l'extrémité (17) du bras d'interposition (9) arrive au contact de la paroi de la coque (B) du boítier, tout en restant guidée par la nervure (10) du couvercle. Un jeu fonctionnel subsiste entre le doigt d'actionnement (14) et le côté (24) de l'encoche (16). Un jeu subsiste également entre le profil d'extrémité latérale (18), situé à cause de la course d'usure en bas du bras d'interposition (9), et le chant en vis-à-vis du contact mobile (6).In the upper part, the end (17) of the interposing arm (9) comes into contact of the shell wall (B) of the case, while remaining guided by the rib (10) of the lid. A functional clearance remains between the actuating finger (14) and the side (24) of the notch (16). There is also clearance between the end profile lateral (18), located because of the wear stroke at the bottom of the interposing arm (9), and the edge facing the movable contact (6).

Ainsi, passé le choc contre la marche (23), dû à la poussée brutale du contact mobile (6) lorsque le ressort (7) restitue son énergie, ledit bras (9) peut revenir à une position intermédiaire, sous l'action de son poids, position intermédiaire par exemple montrée en figure 9. On peut considérer que cette figure montre la position stable correspondant à la fermeture des contacts, au détail près que le profil (18) est alors probablement au contact du chant latéral du contact mobile (6) du fait de l'action de son poids. Cette rotation inverse le long de la contremarche (23) est rendue possible par la forme cylindrique du doigt d'actionnement (14).Thus, past the shock against walking (23), due to the sudden push of the contact mobile (6) when the spring (7) returns its energy, said arm (9) can return to an intermediate position, under the action of its weight, intermediate position by example shown in figure 9. We can consider that this figure shows the stable position corresponding to the closing of the contacts, except that the profile (18) is then probably in contact with the side edge of the movable contact (6) due to the action of its weight. This rotation reverses along the riser (23) is made possible by the cylindrical shape of the actuating finger (14).

Un mouvement de rotation inverse imprimé à la manette (1), visant à l'ouverture des contacts, conduit à une rotation également inverse du contact mobile (6), qui s'efface par conséquent devant l'extrémité inférieure, et en particulier le profil (18) du bras d'interposition (9). Le doigt d'actionnement (14) étant lui aussi mu par un mouvement inverse, il se rapproche du côté opposé (26) de l'encoche (16), entre en contact avec lui et repousse le bras (9) vers sa position initiale telle que montrée en figures 1 et 2.A reverse rotation movement printed on the handle (1), aimed at opening contacts, also leads to a reverse rotation of the movable contact (6), which consequently disappears in front of the lower end, and in particular the profile (18) of the interposing arm (9). The actuating finger (14) also being moved by a reverse movement, it approaches the opposite side (26) of the notch (16), between in contact with it and pushes the arm (9) back to its initial position such that shown in Figures 1 and 2.

Dans le cas où les contacts restent soudés, comme cela apparaít en figure 10, le coulissement vers le bas est empêché par l'existence de la contremarche (22), et la rotation de la manette est alors stoppée par l'obstacle au déplacement du doigt d'actionnement (14) constitué par ledit côté (26). Il n'est pas possible d'obtenir le retour de la manette en position d'ouverture des contacts. La fonction de sectionnement est alors bien assurée.In the case where the contacts remain soldered, as it appears in Figure 10, the sliding down is prevented by the existence of the riser (22), and the rotation of the lever is then stopped by the obstacle to the movement of the finger actuator (14) formed by said side (26). It is not possible to obtain the return of the lever to the open position of the contacts. The function of sectioning is then well ensured.

La figure 11 correspond, en perspective, à la figure 10, et elle permet de se faire une idée plus précise des différents reliefs impliqués dans les mouvements des éléments précités. La coque (B) est dépourvue de son couvercle (C), et certains des éléments de guidage, notamment axiaux, ne sont donc pas montrés. L'intérêt de cette figure est cependant de mettre en lumière le fait que le bras d'interposition (9) est simplement posé sur les composants qui le précèdent dans l'ordre de montage de l'appareil électrique de l'invention, la pose ultérieure du couvercle permettant de terminer la mise en place des guidages impliquant une double relation au boítier et aux autres composants.Figure 11 corresponds, in perspective, to Figure 10, and it allows to get a better idea of the different reliefs involved in the movements of the above. The shell (B) is devoid of its cover (C), and some of the guide elements, in particular axial, are therefore not shown. The interest of this figure is however to highlight the fact that the arm (9) is simply placed on the components that precede it in the assembly order of the electrical device of the invention, the subsequent installation of the cover to complete the installation of the guides involving a double relationship to the housing and other components.

L'invention a été décrite, en référence aux figures précitées, selon un de ses modes de réalisation, qui n'en constitue qu'un exemple non exhaustif. Les variantes de forme et de configuration qui sont à la portée de l'homme de l'art sont bien entendu comprises dans l'invention.The invention has been described, with reference to the aforementioned figures, according to one of its embodiments, which is only a non-exhaustive example. The variants of shape and configuration which are within the reach of ordinary skill in the art are of course included in the invention.
