Abstract

A rotating control element is connected to a control rod oriented toward one of the two orthogonal control axles corresponding to the front and lateral control modes. A transmission element is connected to a movable contact to transform rotation by control element on one of the orthogonal control axles into translational movement by movable contact between the released and engaged positions with respect to fixed contacts.

Description

La présente invention concerne un appareil de coupure électrique à commande frontale ou latérale pour une installation électrique comportant au moins un boîtier pourvu au moins d'une paire de bornes de raccordement destinée à être raccordée à au moins un conducteur électrique de ladite installation et reliée à une paire de contacts fixes, ledit boîtier comportant au moins un contact mobile et au moins une tige de commande traversant ledit boîtier et couplée extérieurement à un organe de manoeuvre et intérieurement audit contact mobile par un mécanisme de transmission pour le déplacer entre une position déclenchée, dans laquelle le contact mobile est éloigné des contacts fixes et le circuit électrique est ouvert, et une position enclenchée, dans laquelle il est en appui contre les contacts fixes et le circuit électrique est fermé.The present invention relates to a front or side-operated electrical switching device for an electrical installation comprising at least one housing provided with at least one pair of connection terminals intended to be connected to at least one electrical conductor of said installation and connected to a pair of fixed contacts, said housing comprising at least one movable contact and at least one control rod passing through said housing and coupled externally to an operating member and internally to said movable contact by a transmission mechanism for moving it between a triggered position, wherein the movable contact is remote from the fixed contacts and the electrical circuit is open, and an engaged position, in which it bears against the fixed contacts and the electrical circuit is closed.

Ces appareils de coupure sont appelés communément interrupteurs, interrupteurs-fusibles, commutateurs; commutateurs-inverseurs, etc. et sont destinés à distribuer l'énergie dans des installations électriques ou à commander des équipements industriels, machines outils, etc., notamment en basse tension alternative, par exemple 380 V, et dans une plage de courant de quelques dizaines à quelques centaines d'ampères.These switching devices are commonly called switches, fuse switches, switches; reversing switches, etc. and are intended to distribute energy in electrical installations or to control industrial equipment, machine tools, etc., in particular in low-voltage alternating, for example 380 V, and in a current range of a few tens to a few hundred amps.

Selon les installations électriques, la configuration des armoires de commande électrique et les options de montage, ces appareils de coupure sont commandés manuellement par un organe de manoeuvre qui peut être une poignée rotative placée soit en façade et on parle de "poignée frontale", soit sur le côté et on parle de "poignée latérale" ou encore un levier basculant généralement placé en façade. Ces appareils de coupure peuvent être, le cas échéant, commandés automatiquement par une motorisation couplée à la tige de commande soit en façade, soit sur le côté.According to the electrical installations, the configuration of the electrical control cabinets and the mounting options, these cut-off devices are manually controlled by an operating member which may be a rotary handle placed either on the front and is referred to as a "front handle" or on the side and there is talk of "side handle" or a rocker lever usually placed on the front. These cut-off devices can be, if necessary, automatically controlled by a motor coupled to the control rod either in front or on the side.

Selon le mode de commande frontal ou latéral, le mécanisme de transmission diffère. D'une manière générale, en commande frontale, ce mécanisme de transmission comporte un système à came qui transforme le mouvement de rotation de la poignée transmis à la tige de commande en un mouvement de translation des contacts mobiles. En commande latérale, ce mécanisme de transmission est complété par un renvoi d'angle. De manière également courante, le mécanisme de transmission est couplé à un dispositif à actionnement brusque qui, indépendamment de la vitesse de rotation de la poignée ou de basculement du levier, permet d'accélérer la vitesse à l'enclenchement et/ou au déclenchement, selon les besoins.Depending on the front or side control mode, the transmission mechanism differs. In general, in front control, this transmission mechanism comprises a cam system that transforms the rotational movement of the handle transmitted to the control rod in a translational movement of the movable contacts. In lateral control, this transmission mechanism is completed by an angle gear. Also commonly, the transmission mechanism is coupled to a sudden-action device which, regardless of the speed of rotation of the handle or tilting of the lever, speeds up the speed at engagement and / or tripping, as required.

Par conséquent, les constructeurs sont dans l'obligation de proposer des modèles d'appareils de coupure différents en fonction à la fois de la gamme de courant et du mode de commande frontal ou latéral. Ce qui signifie que, dans une même gamme de courant, un modèle d'appareil de coupure est décliné en plusieurs versions selon que la commande est frontale ou latérale. Certains constructeurs proposent des appareils de coupure dits polyvalents et agencés pour répondre aux deux modes de commande frontal et latéral. Toutefois, ces appareils de coupure polyvalents comportent des mécanismes de transmission complexes et onéreux compte tenu du nombre de pièces important, dont la fiabilité mécanique n'est pas optimale notamment en terme de durée de vie. De plus, l'encombrement de ce type d'appareils est pénalisé.As a result, manufacturers are required to offer different models of switching devices based on both the current range and the front or side control mode. Which means that, in the same range of current, a model of breaking device is declined in several versions according to whether the control is front or side. Some manufacturers offer so-called cutting devices versatile and arranged to meet the two modes of front and side control. However, these versatile cutting devices have complex transmission mechanisms and expensive given the large number of parts, whose mechanical reliability is not optimal especially in terms of service life. In addition, the size of this type of device is penalized.

La présente invention vise à pallier ces inconvénients en proposant un appareil de coupure dit polyvalent qui puisse répondre à tous les modes de commande et réalisé avec un minimum de pièces pour qu'il soit simple, économique, fiable mécaniquement et d'un encombrement standard.The present invention aims to overcome these disadvantages by providing a so-called versatile cutting device that can respond to all control modes and made with a minimum of parts so that it is simple, economical, mechanically reliable and a standard size.

Dans ce but, l'invention concerne un appareil de coupure du genre indiqué en préambule, caractérisé en ce que le mécanisme de transmission comporte au moins un organe de commande rotatif agencé pour être couplé à la tige de commande orientée selon l'un ou l'autre de deux axes de commande orthogonaux correspondant respectivement à l'un des deux modes de commande frontal et latéral de manière à faire tourner l'organe de commande selon l'un ou l'autre de ces axes de commande et au moins un organe de transmission couplé au contact mobile et agencé pour transformer la rotation dudit organe de commande selon l'un ou l'autre de ces axes de commande en une translation dudit contact mobile entre les positions déclenchée et enclenchée et inversement.For this purpose, the invention relates to a cutting device of the kind indicated in the preamble, characterized in that the transmission mechanism comprises at least one rotary control member arranged to be coupled to the oriented control rod. according to one or other of two orthogonal control axes respectively corresponding to one of the two front and side control modes so as to rotate the control member according to one or other of these axes of control and at least one transmission member coupled to the movable contact and arranged to transform the rotation of said control member according to one or other of these control axes into a translation of said movable contact between the triggered and engaged positions and vice versa.

Dans une forme de réalisation préférée, le mécanisme de transmission comporte un dispositif à actionnement brusque agencé pour coopérer avec l'organe de commande rotatif de manière à le faire tourner automatiquement et rapidement au-delà d'une position d'équilibre prédéterminée.In a preferred embodiment, the transmission mechanism includes a snap-action device arranged to cooperate with the rotary actuator to automatically and rapidly rotate beyond a predetermined equilibrium position.

Il comporte un boîtier 2 isolé électriquement, de dimensions standardisées et apte à se monter sur des rails normalisés prévus par exemple dans des armoires de commande électrique. Il comporte un nombre de paires de bornes de raccordement 3 ou de pôles adapté au nombre de phases ou de conducteurs de l'installation électrique et par exemple trois comme dans les exemples représentés. Ces bornes de raccordement 3 sont à vis mais peuvent être à ressort ou pourvues de tout autre mode de raccordement existant.It comprises a housing 2 electrically insulated, standardized dimensions and adapted to be mounted on standardized rails provided for example in electrical control cabinets. It comprises a number of pairs of connection terminals 3 or poles adapted to the number of phases or conductors of the electrical installation and for example three as in the examples shown. These connection terminals 3 are screw but can be spring loaded or provided with any other existing connection mode.

Ce type d'appareil de coupure 1 peut être commandé par un organe de manoeuvre 4 extérieur au boîtier 2 et monté en face avant ou sur le côté et lié à une tige de commande 5. Les figures 1A-D illustrent respectivement quatre appareils de coupure 1a-d commandés selon différents modes : en mode frontal selon un premier axe de commande A, soit par une poignée 4a montée en face avant selon la figure 1A et mobile en rotation d'un quart de tour entre deux positions 0 et 1, soit par un levier 4b monté en face avant selon la figure 1B et basculant sur 90° entre deux positions 0 et 1, ou en mode latéral selon un second axe de commande B perpendiculaire au premier, par une ou deux poignées 4c montées sur les côtés selon la figure 1C et mobiles en rotation d'un quart de tour entre deux positions 0 et 1. Le mode de commande latéral permet le couplage d'appareils de coupure 1d de même calibre ou de calibres différents. Un exemple est illustré à la figure ID où deux appareils de coupure 1d identiques sont couplés pour doubler le nombre de bornes de raccordement 3 disponibles et commandés simultanément par une poignée 4d montée sur un des côtés du boîtier 2 et une tige de commande 5 rallongée traversant les deux boîtiers 2.This type of cut-off device 1 can be controlled by an operating member 4 outside the housing 2 and mounted on the front face or on the side and connected to a control rod 5. FIGS. 1A-D respectively illustrate four cut-off devices 1a-d controlled according to different modes: in frontal mode according to a first control axis A, or by a handle 4a mounted on the front face according to Figure 1A and movable in rotation by a quarter turn between two positions 0 and 1, or by a lever 4b mounted on the front face according to FIG. 1B and swinging through 90 ° between two positions 0 and 1, or in lateral mode along a second control axis B perpendicular to the first, by one or two handles 4c mounted on the sides according to FIG. 1C and movable in rotation by a quarter of a turn between two positions 0 and 1. The lateral control mode allows the coupling of cutoff devices 1d of the same caliber or different calibers. An example is shown in FIG ID where two identical disconnecting apparatus 1d are coupled to double the number of connection terminals 3 available and controlled simultaneously by a handle 4d mounted on one of the sides of the housing 2 and a control rod 5 extending through the two housings 2.

L'intérieur de l'appareil de coupure 1 selon l'invention est représenté sur la figure 2 en vue éclatée. Il comporte trois paires de bornes de raccordement à vis 3, chacune couplée à une paire de contacts fixes 6. A chaque paire de contacts fixes 6 correspond un contact mobile 7 apte à ouvrir ou à fermer le circuit électrique entre les contacts fixes 6 d'une même paire. Les contacts mobiles 7 sont assujettis chacun à un élément de rappel 8 en direction des contacts fixes 6 et sont déplacés de manière simultanée par l'organe de manoeuvre extérieur 4 via la tige de commande 5 et un mécanisme de transmission 10 entre une position déclenchée, dans laquelle les contacts mobiles 7 sont éloignés des contacts fixes 6 et le circuit électrique est ouvert, et une position enclenchée, dans laquelle ils sont en appui contre les contacts fixes 6 et le circuit électrique est fermé.The inside of the breaking device 1 according to the invention is shown in FIG. 2 in an exploded view. It comprises three pairs of screw connection terminals 3, each coupled to a pair of fixed contacts 6.

Le mécanisme de transmission 10 comporte un organe de commande rotatif 20 couplé à la tige de commande 5 orientée selon le premier ou le second axe de commande A, B correspondant au mode de commande respectivement frontal ou latéral et un organe de transmission 30 couplé aux contacts mobiles 7 et agencé pour transformer la rotation de l'organe de commande 20 selon l'un ou l'autre de ces deux axes de commande A, B en une translation des contacts mobiles 7 entre les positions déclenchée et enclenchée et inversement.The transmission mechanism 10 comprises a rotary control member 20 coupled to the control rod 5 oriented according to the first or the second control axis A, B corresponding to the control mode respectively frontal or lateral and a transmission member 30 coupled to the contacts 7 and arranged to transform the rotation of the control member 20 according to one or other of these two axes of control A, B in a translation of the movable contacts 7 between the triggered and engaged positions and vice versa.

L'organe de commande rotatif 20 est constitué d'une pièce mobile et libre par rapport au boîtier 2 (non représenté). Il comporte deux alésages carrés 21 d'axes orthogonaux et confondus avec les axes de commande A et B pour recevoir en prise directe l'extrémité correspondante de la tige de commande 5 également de section carrée. Bien entendu, d'autres types d'accouplement peuvent convenir selon la section de la tige de commande 5. Cet organe de commande rotatif 20 a une section en forme d'étoile à quatre branches 22 selon deux plans de symétrie orthogonaux définissant huit faces inclinées 23 et quatre sommets 24, tous les angles étant arrondis. Les deux plans de symétrie orthogonaux se coupent en un axe de symétrie confondu avec le premier axe de commande A. L'organe de commande rotatif 20 comporte en regard de l'organe de transmission 30 une extrémité profilée 25 en V définissant un sommet arrondi formant un doigt linéaire 26 et deux faces inclinées 27 symétriques par rapport à un plan passant par les deux axes de commande A et B.The rotary control member 20 consists of a movable and free piece relative to the housing 2 (not shown). It comprises two square bores 21 of orthogonal axes and merged with the control axes A and B to directly receive the corresponding end of the control rod 5 also of square section. Of course, other types of coupling may be suitable according to the section of the control rod 5. This rotary control member 20 has a star-shaped section with four branches 22 in two orthogonal planes of symmetry defining eight inclined faces 23 and four vertices 24, all corners being rounded. The two orthogonal planes of symmetry intersect in an axis of symmetry confused with the first control axis A. The rotary control member 20 comprises facing the transmission member 30 a profiled end 25 V defining a rounded apex forming a linear finger 26 and two inclined faces 27 symmetrical with respect to a plane passing through the two control axes A and B.

L'organe de transmission 30 comporte un barreau 31 mobile en translation par rapport au boîtier 2 (non représenté) et guidé par ce dernier au moyen des formes complémentaires telles que des nervures coulissant dans des rails 32. Cet organe de transmission 30, représenté en détail à la figure 7, comporte d'un côté des logements de guidage 33 pour les contacts mobiles 7 et de l'autre côté un plot à came multiple 40 en regard de l'organe de commande rotatif 20, une zone d'appui 34 pour un organe de verrouillage 50 et une rainure de circulation 35 pour cet organe de verrouillage 50. Le plot à came multiple 40 est centré sur l'axe de commande A et comporte un fond plan 41 entouré de deux bossages semi-annulaires diamétralement opposés par rapport à cet axe de commande A définissant deux rampes inclinées 42, 43 de pentes différentes. Le fond plan 41 s'étend sur un secteur angulaire d'environ 45° et se poursuit par une première rampe inclinée 42 à forte pente sur un secteur angulaire d'environ 45°. Cette première rampe inclinée 42 est doublée et diamétralement opposée par rapport à l'axe de commande A. La hauteur de cette première rampe inclinée 42 est sensiblement égale à la course des contacts mobiles 7 entre leurs positions enclenchée et déclenchée. Ce fond plan 41 et cette première rampe inclinée 42 coopèrent avec le doigt linéaire 26 formé à l'extrémité profilée 25 de l'organe de commande rotatif 20 lorsqu'il est en rotation autour du premier axe de commande A. La seconde rampe inclinée 43 a une pente moins forte, s'étend sur un secteur d'environ 90°, est opposée à la première rampe inclinée 42, doublée et diamétralement opposée par rapport à l'axe de commande A. Elle coopère avec une des faces inclinées 27 et le doigt linéaire 26 de l'extrémité profilé 25 de l'organe de commande rotatif 20 lorsqu'il est en rotation autour du second axe de commande B. Les rampes inclinées 42, 43 de pentes différentes se rejoignent deux à deux en un sommet 44 formant une arête d'extrémité contenue dans un plan passant par les deux axes de commande A et B.The transmission member 30 comprises a bar 31 movable in translation relative to the housing 2 (not shown) and guided by the latter by means of complementary shapes such as ribs sliding in rails 32. This transmission member 30, shown in FIG. detail in Figure 7, has on one side guiding housings 33 for the movable contacts 7 and on the other side a multiple cam follower 40 facing the rotary control member 20, a bearing zone 34 for a locking member 50 and a circulation groove 35 for this locking member 50. The multiple cam pad 40 is centered on the control pin A and has a flat bottom 41 surrounded by two semi-annular bosses diametrically opposed by relative to this control axis A defining two inclined ramps 42, 43 of different slopes. The bottom plane 41 extends over an angular sector of approximately 45 ° and continues with a first inclined ramp 42 with a steep slope over an angular sector about 45 °. This first inclined ramp 42 is doubled and diametrically opposite with respect to the control axis A. The height of this first inclined ramp 42 is substantially equal to the stroke of the movable contacts 7 between their engaged and tripped positions. This flat bottom 41 and this first inclined ramp 42 cooperate with the linear finger 26 formed at the profiled end 25 of the rotary control member 20 when it is rotating about the first control axis A. The second inclined ramp 43 has a less steep slope, extends over a sector of about 90 °, is opposite the first inclined ramp 42, doubled and diametrically opposite with respect to the control axis A. It cooperates with one of the inclined faces 27 and the linear finger 26 of the profiled end 25 of the rotary control member 20 when it is rotating about the second control axis B. The inclined ramps 42, 43 of different slopes meet two by two in a vertex 44 forming an end edge contained in a plane passing through the two control axes A and B.

Le mécanisme de transmission 10 comporte également un dispositif à actionnement brusque 60 pourvu de deux pistons 61 disposés de part et d'autre de l'organe de commande rotatif 20 et mobiles en translation par rapport au boîtier 2 (non représenté) dans des directions opposées. Chaque piston 61 comporte un alésage central 62 apte à recevoir librement la tige de commande 5 en mode latéral et est assujetti à des moyens ressort 63 en directement de l'organe de commande rotatif 20 pour lui assurer un positionnement correct et stable par rapport au boîtier 2 et aux autres mécanismes. Chaque piston 61 comporte, en regard de l'organe de commande rotatif 20, deux évidements 64 en forme de V selon deux plans de symétrie orthogonaux définissant quatre rampes inclinées 65 et quatre sommets 66, tous les angles étant arrondis.The transmission mechanism 10 also comprises a device 60 with sudden actuation provided with two pistons 61 disposed on either side of the rotary control member 20 and movable in translation relative to the housing 2 (not shown) in opposite directions . Each piston 61 has a central bore 62 capable of freely receiving the control rod 5 in lateral mode and is subjected to spring means 63 directly from the rotary control member 20 to ensure a correct and stable positioning relative to the housing 2 and other mechanisms. Each piston 61 comprises, facing the rotary control member 20, two recesses 64 in the form of V in two orthogonal planes of symmetry defining four inclined ramps 65 and four vertices 66, all angles being rounded.

Ce dispositif à actionnement brusque 60 comporte également au moins un organe de verrouillage 50 disposé entre au moins un des pistons 61 et l'organe de transmission 30. Il est mobile en translation par rapport au boîtier 2 (non représenté) entre au moins une position verrouillée dans laquelle il bloque l'organe de transmission 30 au moins dans la position déclenchée et une position déverrouillée dans laquelle il le libère pour l'autoriser à se déplacer dans la position enclenchée. Cet organe de verrouillage 50 est couplé à un des pistons 61 qui l'entraîne dans une direction opposée à l'organe de commande 20 et est assujetti à des moyens de rappel 51 qui l'entraînent dans l'autre direction vers l'organe de commande 20. Dans l'exemple représenté, cet organe de verrouillage 50 est constitué d'une pièce en L distincte du piston 61 et couplé en translation à ce dernier au travers d'un logement 67. Dans d'autres variantes non représentées, il peut être solidaire du piston et avoir un degré de liberté en rotation par rapport à lui. De même, il est possible de prévoir deux organes de verrouillage 50 travaillant simultanément et en opposition.This abruptly actuated device 60 also comprises at least one locking member 50 disposed between at least one of the pistons 61 and the transmission member 30. It is movable in translation relative to the housing 2 (not shown) between at least one locked position in which it blocks the transmission member 30 at least in the triggered position and an unlocked position in which it releases it to allow it to move into the engaged position. This locking member 50 is coupled to one of the pistons 61 which drives it in a direction opposite to the control member 20 and is subject to return means 51 which drive it in the other direction to the control member. 20. In the example shown, this locking member 50 consists of a separate L-shaped part of the piston 61 and coupled in translation to the latter through a housing 67. In other variants not shown, it can be integral with the piston and have a degree of freedom in rotation relative to it. Similarly, it is possible to provide two locking members 50 working simultaneously and in opposition.

Le boîtier 2 (non représenté) comporte une platine intermédiaire 70 disposée entre l'organe de transmission 30 et l'ensemble formé par l'organe de commande 20 et les pistons 61. Cette platine intermédiaire 70 comporte notamment une rainure de guidage 71 en translation pour l'organe de verrouillage 50 et des logements de guidage 72 en translation pour les pistons 61. Elle assure à la fois le guidage en translation de ces pièces et la répartition des efforts encaissée notamment par l'organe de verrouillage 50 en position verrouillée, épargnant ainsi les pistons 61.The housing 2 (not shown) comprises an intermediate plate 70 disposed between the transmission member 30 and the assembly formed by the control member 20 and the pistons 61. This intermediate plate 70 comprises in particular a guide groove 71 in translation for the locking member 50 and guide housings 72 in translation for the pistons 61. It provides both the guide in translation of these parts and the distribution of the forces cashed in particular by the locking member 50 in the locked position, thus sparing the pistons 61.

Le fonctionnement de l'appareil de coupure 1 selon l'invention est à présent décrit en référence aux figures 3 et 4 qui correspondent à une commande en mode frontal, à savoir selon l'axe de commande A.
Les figures 3A et 4A illustrent l'appareil de coupure 1 en position déclenchée. Les organes de commande rotatif 20 et de transmission 30 sont en contact sur leurs sommets 26, 44, le doigt linéaire 26 reposant sur le sommet 44 du plot à came multiple 40. Les pistons 61 bloquent l'organe de commande rotatif 20 dans une position stable, leurs moyens ressort 63 étant détendus. L'organe de commande rotatif 20 est dans une position stable étant donné que deux de ses branches 22 opposées sont logées dans les évidements 64 des pistons 61. L'organe de verrouillage 50 bloque l'organe de transmission 30 enfoncé en position déclenchée, ses moyens de rappel 51 étant détendus. Les éléments de rappel 8 des contacts mobiles 7 sont comprimés.
Les figures 3B et 4B illustrent l'appareil de coupure 1 en position d'équilibre déclenchée. Un opérateur a tourné l'organe de manoeuvre extérieur 4 (non représenté) d'un huitième de tour entraînant l'organe de commande rotatif 20 sur une première partie de sa course soit un huitième de tour par le biais de la tige de commande 5 selon l'axe de commande A. Les sommets 24 des deux branches 22 opposées de l'étoile logées dans le fond des évidements 64 correspondants des pistons 61 coulissent sur les rampes inclinées 65 correspondantes provoquant le recul des pistons 61 et la compression des moyens ressort 63 jusqu'à ce que les sommets 24 atteignent les pointes 66 des pistons 61 marquant la position d'équilibre. Simultanément, le recul d'un des pistons 61 entraîne l'organe de verrouillage 50 et comprime ses moyens de rappel 51. L'organe de verrouillage 50 maintient l'organe de transmission 30 en position enfoncée tant qu'il est dans la zone d'appui 34 et jusqu'à ce qu'il soit en regard de la rainure de circulation 35.
Les figures 3C et 4C illustrent l'appareil de coupure 1 en position enclenchée. En poursuivant la rotation de l'organe de manoeuvre extérieur 4, l'opérateur a dépassé la position d'équilibre mettant en oeuvre le dispositif à actionnement brusque 60 pour basculer très rapidement de la position déclenchée à la position enclenchée. Dès que les sommets 24 des deux branches 22 opposées de l'étoile quittent les pointes 66 correspondantes des pistons 61, l'effort résistant sur les moyens ressort 63 s'annule, ils se détendent et rapprochent les pistons 61 de l'organe de commande rotatif 20 en provoquant automatiquement et rapidement sa rotation sur la deuxième partie de sa course soit un huitième de tour. Simultanément, l'organe de verrouillage 50 ayant quitté la zone d'appui 34 et étant face à la rainure de circulation 35 n'exerce plus d'effort résistant sur les éléments de rappel 8 des contacts mobiles 7, ils se relâchent, poussent sur les contacts mobiles 7 et provoquent la remontée de l'organe de transmission 30 en position enclenchée. Simultanément, l'extrémité profilée 25 de l'organe de commande rotatif 20 se loge dans le plot à came multiple 40, le doigt linéaire 26 étant en butée contre le fond plan 41 autorisant sa rotation sur la deuxième partie de sa course. L'appareil de coupure 1 est en position enclenchée.The operation of the breaking device 1 according to the invention is now described with reference to FIGS. 3 and 4 which correspond to a control in frontal mode, namely along the control axis A.
Figures 3A and 4A illustrate the switchgear 1 in the tripped position. The rotary control members 20 and transmission 30 are in contact on their vertices 26, 44, the linear finger 26 resting on the top 44 of the multiple cam pad 40. The pistons 61 block the rotary control member 20 in a position stable, their spring means 63 being relaxed. The rotary control member 20 is in a stable position since two of its opposite branches 22 are housed in the recesses 64 of the pistons 61. The locking member 50 blocks the transmission member 30 pressed into the triggered position, its biasing means 51 being relaxed. The return elements 8 of the movable contacts 7 are compressed.
Figures 3B and 4B illustrate the switchgear 1 in the triggered equilibrium position. An operator has rotated the external operating member 4 (not shown) by an eighth of a turn driving the rotational control member 20 on a first portion of its stroke or an eighth of a turn through the control rod 5 along the control axis A. The vertices 24 of the two opposite branches 22 of the star housed in the bottom of the corresponding recesses 64 of the pistons 61 slide on the corresponding inclined ramps 65 causing the recoil of the pistons 61 and the compression of the spring means 63 until the peaks 24 reach the tips 66 of the pistons 61 marking the equilibrium position. Simultaneously, the recoil of one of the pistons 61 drives the locking member 50 and compresses its biasing means 51. The locking member 50 holds the transmission member 30 in the depressed position as long as it is in the zone d 34 and until it is facing the circulation groove 35.
Figures 3C and 4C illustrate the switchgear 1 in the engaged position. By continuing the rotation of the external actuator 4, the operator has exceeded the equilibrium position implementing the sudden-action device 60 to switch very quickly from the triggered position to the engaged position. As soon as the peaks 24 of the two opposite branches 22 of the star leave the corresponding tips 66 of the pistons 61, the resisting force on the spring means 63 vanishes, they relax and bring the pistons 61 close to the control member rotating 20 automatically causing rapid rotation on the second part of its race is an eighth turn. Simultaneously, the locking member 50 having left the bearing zone 34 and facing the circulation groove 35 no longer exerts a resisting force on the return elements 8 of the movable contacts 7, they relax, push on the movable contacts 7 and cause the raising of the transmission member 30 in the engaged position. At the same time, the profiled end 25 of the rotary control member 20 is housed in the multiple cam stud 40, the linear finger 26 being in abutment against the flat bottom 41 allowing its rotation on the second part of its stroke. The switchgear 1 is in the engaged position.

Pour basculer en position déclenchée, l'opérateur doit tourner l'organe de manoeuvre extérieur 4 en sens inverse. Dans la première partie de sa course, soit un huitième de tour, l'organe de commande rotatif 20 tourne d'un huitième de tour sans effet sur l'organe de transmission 30, le doigt linéaire 26 circulant dans le fond plan 41 du plot à came multiple 40. Simultanément, le sommet 24 des deux autres branches 22 de l'étoile deviennent actifs et coulissent sur les rampes inclinées 65 des pistons 61 en les faisant reculer et en comprimant leur moyens ressort 63 jusqu'à atteindre les pointes 66 correspondantes marquant la position d'équilibre. Simultanément, un des pistons 61 entraîne avec lui l'organe de verrouillage 50 en comprimant ses moyens de rappel 51.
Passé la position d'équilibre, les pistons 61 sous l'action de leurs moyens ressort 63 provoquent automatiquement et rapidement la rotation de l'organe de commande 20 sur la deuxième partie de sa course, soit un huitième de tour, jusqu'à atteindre une position stable, deux branches 22 opposées de l'étoile étant logées dans les évidements 64 correspondants des pistons 61. Simultanément, le doigt linéaire 26 de l'extrémité profilée 25 de l'organe de commande rotatif 20 circule sur les premières rampes inclinées 42 à forte pente générant le recul de l'organe de transmission 30, la séparation des contacts mobiles 7 par rapport aux contacts fixes 6 et la compression de leurs éléments de rappel 8. En fin de course de l'organe de commande rotatif 20, lorsque la position déclenchée est atteinte, l'organe de verrouillage 50 se rapproche de l'organe de commande rotatif 20 sous l'action de ses moyens de rappel 51 pour se positionner en butée sur la zone d'appui 34 de l'organe de transmission 30 le bloquant dans sa position déclenchée. Les efforts de poussée des éléments de rappel 8 des contacts mobiles 7 sont alors transmis à l'organe de verrouillage 50 et répartis dans la platine intermédiaire 70. Par cette construction, les pistons 61 ne subissent aucun effort parasite risquant de perturber leur guidage en translation.To switch to the triggered position, the operator must turn the external actuator 4 in the opposite direction. In the first part of its stroke, ie one-eighth of a turn, the rotary control member 20 rotates an eighth of a turn without any effect on the transmission member 30, the linear finger 26 flowing in the plane bottom 41 of the stud At the same time, the top 24 of the other two branches 22 of the star become active and slide on the inclined ramps 65 of the pistons 61 by moving them back and compressing their spring means 63 until reaching the corresponding peaks 66 marking the equilibrium position. Simultaneously, one of the pistons 61 carries with it the locking member 50 by compressing its return means 51.
After the equilibrium position, the pistons 61 under the action of their spring means 63 automatically and rapidly cause the rotation of the control member 20 on the second part of its stroke, ie one eighth of a revolution, until it reaches a stable position, two opposed branches 22 of the star being housed in the corresponding recesses 64 of the pistons 61. Simultaneously, the linear finger 26 of the profiled end 25 of the rotary control member 20 circulates on the first inclined ramps 42 with a steep slope generating the recoil of the transmission member 30, the separation of the movable contacts 7 relative to the fixed contacts 6 and the compression of their return elements 8. At the end of the race of the rotary control member 20, when the triggered position is reached, the locking member 50 approaches the rotary control member 20 under the action of its return means 51 to position itself in abutment on the support zone 34 of the o transmission member 30 blocking it in its triggered position. The thrust forces of the return elements 8 of the movable contacts 7 are then transmitted to the locking member 50 and distributed in the intermediate plate 70. By this construction, the pistons 61 do not undergo any parasitic force that may disturb their guidance in translation.

Le fonctionnement de l'appareil de coupure 1 selon l'invention commandé en mode latéral est sensiblement identique. En référence aux figures 5A-B, l'appareil de coupure 1 est représenté respectivement en positions d'équilibre et enclenchée, la position déclenchée étant conforme à la figure 3A. La tige de commande 5 est couplée à l'organe de commande rotatif 20 suivant le second axe de commande B provoquant sa rotation autour de ce même axe de commande B dans le sens de rotation ou de basculement de l'organe de manoeuvre extérieur 4 (non représenté). Dans la première partie de sa course, les deux branches 22 opposées de l'étoile circulent sur les rampes inclinées 65 correspondantes et diamétralement opposées des pistons 61 provoquant leur recul. Simultanément, l'extrémité profilée 25 de l'organe de commande rotatif 20 tourne librement, sans entrer en collision avec l'organe de transmission 30, ce dernier étant bloqué en position déclenchée par l'organe de verrouillage 50 jusqu'à la position d'équilibre (cf. fig. 5A). Au-delà de cette position d'équilibre, les pistons 61 provoquent automatiquement et rapidement la rotation de l'organe de commande 20 sur la deuxième partie de sa course, cette rotation étant possible du fait que l'extrémité profilée 25 de l'organe de commande rotatif 20 reste extérieure au plot à came multiple 40. Simultanément, l'organe de verrouillage 50 libère l'organe de transmission 30 qui remonte en position enclenchée (cf. fig. 5B).The operation of the switching device 1 according to the invention controlled in lateral mode is substantially identical. With reference to FIGS. 5A-B, the cut-off apparatus 1 is represented in equilibrium and engaged positions respectively, the triggered position being in accordance with FIG. 3A. The control rod 5 is coupled to the rotary control member 20 along the second control axis B causing it to rotate about the same control axis B in the direction of rotation or tilting of the external actuating member 4 (FIG. not shown). In the first part of its travel, the two opposite branches 22 of the star circulate on the corresponding inclined ramps 65 and diametrically opposed pistons 61 causing their recoil. Simultaneously, the profiled end 25 of the rotary control member 20 rotates freely, without colliding with the transmission member 30, the latter being locked in the triggered position by the locking member 50 to the position d balance (see Fig. 5A). Beyond this equilibrium position, the pistons 61 automatically and rapidly cause the control member 20 to rotate on the second part of its stroke, this rotation being possible because the profiled end 25 of the organ rotary control 20 remains external to the multi-cam pad 40. Simultaneously, the locking member 50 releases the transmission member 30 which rises in the engaged position (see Fig. 5B).

Le basculement de l'appareil de coupure 1 des figures 5A-B de la position enclenchée à la position déclenchée est illustré par les figures 6A-C. La figure 6A correspond à la position enclenchée de la figure 5B. L'opérateur actionne l'organe de manoeuvre extérieur 4 pour provoquer la rotation de l'organe de commande 20 autour de l'axe de commande B sur une première partie de sa course, soit un huitième de tour, jusqu'à atteindre la position d'équilibre (cf. fig. 6B). Cette rotation est possible étant donné que l'extrémité profilée 25 de l'organe de commande rotatif 20 est située à l'extérieur du plot à came multiple 40 et n'entre pas en conflit avec lui. En position d'équilibre, une des faces inclinées 27 de cette extrémité profilée 25 vient au contact d'une des secondes rampes inclinées 43 à faible pente du plot à came multiple 40. Passé la position d'équilibre, lorsque les pistons 61 provoquent automatiquement et rapidement la rotation de l'organe de commande 20 sur la seconde partie de sa course, soit un huitième de tour, le doigt linéaire 26 prévu sur cette extrémité profilée 25 circule sur la seconde rampe inclinée 43 du plot à came multiple 40 provoquant le recul de l'organe de transmission 30 en position déclenchée (cf. fig. 6C) verrouillée simultanément par l'organe de verrouillage 50.The switching of the switchgear 1 of Figs. 5A-B from the engaged position to the tripped position is illustrated in Figs. 6A-C. Figure 6A corresponds to the engaged position of Figure 5B. The operator actuates the external actuator 4 to cause the rotation of the control member 20 around the control axis B on a first portion of its stroke, an eighth of a turn, until reaching the position equilibrium (see Fig. 6B). This rotation is possible since the profiled end 25 of the rotary control member 20 is located outside of the multi-cam pad 40 and does not conflict with it. In the equilibrium position, one of the inclined faces 27 of this profiled end 25 comes into contact with one of the second inclined ramps 43 at low slope of the multiple cam pad 40. Past the equilibrium position, when the pistons 61 automatically cause and quickly the rotation of the control member 20 on the second part of its stroke, an eighth of a turn, the linear finger 26 provided on this profiled end 25 flows on the second inclined ramp 43 of the multiple cam pad 40 causing the retraction of the transmission member 30 in the tripped position (see FIG 6C) locked simultaneously by the locking member 50.

Il ressort clairement de cette description que l'invention permet d'atteindre les buts fixés, à savoir de proposer un appareil de coupure 1 pourvu d'un mécanisme simple pouvant être commandé aussi bien en mode frontal qu'en mode latéral. Cette option permet la gestion d'un seul modèle d'appareil de coupure 1 par gamme de courant ou par calibre et de donner le choix du mode de commande au client final. De plus, il apparaît que la chaîne cinématique est très courte permettant une transmission de mouvement optimale sans inertie et en limitant la fatigue mécanique des organes en mouvement. Les pièces qui composent cet appareil de coupure sont principalement réalisées en matériaux synthétiques moulés ou injectés, renforcés ou non selon la résistance mécanique recherchée et ayant un faible coefficient de frottement notamment pour les pièces en contact glissant, à savoir l'organe de commande 20, les pistons 61 et l'organe de transmission 30.It is clear from this description that the invention achieves the goals set, namely to provide a switching device 1 provided with a simple mechanism that can be controlled in both frontal mode and lateral mode. This option allows the management of a single cut-off device model 1 per current range or rating and gives the choice of control mode to the end customer. In addition, it appears that the kinematic chain is very short allowing optimal motion transmission without inertia and limiting the mechanical fatigue of moving bodies. The parts that make up this cutting device are mainly made of molded or injected synthetic materials, reinforced or not, depending on the desired mechanical strength, and having a low coefficient of friction, in particular for the parts in sliding contact, namely the control member 20, the pistons 61 and the transmission member 30.
