Description

La présente invention concerne d'une manière générale les coupe-circuit à préhenseur, c'est-à-dire les coupe-circuit comportant, dans un corps, un organe, dit préhenseur, qui présente un évidement propre au logement d'une cartouche fusible, et qui est monté rotatif dans ledit corps entre une position de fermeture, pour laquelle ladite cartouche fusible établit une liaison électrique entre deux contacts interposés entre deux bornes de raccordement, et une position d'extraction, pour laquelle, cette liaison électrique étant interrompue, ledit logement débouche à l'extérieur, pour mise en place ou retrait d'une telle cartouche.The present invention generally relates to gripper circuit breakers, that is to say circuit breakers comprising, in a body, a member, called gripper, which has a recess suitable for housing a cartridge. fuse, and which is rotatably mounted in said body between a closed position, for which said fuse cartridge establishes an electrical connection between two contacts interposed between two connection terminals, and an extraction position, for which, this electrical connection being interrupted , said housing opens to the outside, for fitting or removing such a cartridge.

Elle vise plus particulièrement ceux de ces coupe-circuit à préhenseur qui comportent, en outre, dans leur corps, un interrupteur de sectionnement interposé entre deux autres bornes de raccordement, ledit interrupteur de sectionnement étant normalement ouvert et étant susceptible d'être commandé en fermeture par le préhenseur, lorsque ledit préhenseur est lui-même en position de fermeture.It relates more particularly to those of these gripper circuit breakers which further comprise, in their body, a sectioning switch interposed between two other connection terminals, said sectioning switch being normally open and being capable of being ordered to close. by the gripper, when said gripper is itself in the closed position.

Un tel coupe-circuit à préhenseur et interrupteur de sectionnement se trouve notamment décrit dans le document FR-A Na 2431762.Such a gripper circuit breaker and sectioning switch is described in particular in document FR-A Na 2431762.

Il trouve en particulier son application dans l'équipement des installations polyphasées; par celles de ses bornes de raccordement qui sont contrôlées par la cartouche fusible, il est interposé sur l'une des phases d'une telle installation tandis que, par celles de ses bornes de raccordement qui sont contrôlées par l'interrupteur de sectionnement, il est interposé sur le neutre de cette installation, en sorte que, avant ou après ouverture de la phase concernée, il assure avantageusement une ouverture, une précoupure ou une postcou- pure d'un tel neutre.It finds its application in particular in the equipment of multi-phase installations; by those of its connection terminals which are controlled by the fuse cartridge, it is interposed on one of the phases of such an installation while, by those of its connection terminals which are controlled by the disconnection switch, it is interposed on the neutral of this installation, so that, before or after opening of the phase concerned, it advantageously ensures an opening, a precut or a post-cut of such a neutral.

Dans certaines des formes de mise en oeuvre décrites dans la demande de brevet français mentionnée ci-dessus, c'est par l'intermédiaire d'un organe particulier, dit ci-après par commodité organe intermédiaire, que, pour des raisons de réalisation, le préhenseur est apte à agir sur l'interrupteur de sectionnement.In some of the forms of implementation described in the French patent application mentioned above, it is by the intermediary of a particular organ, said hereinafter by convenience of intermediate organ, that, for reasons of implementation, the gripper is able to act on the sectioning switch.

Cet organe intermédiaire est porté par le corps, en étant monté mobile sur celui-ci.This intermediate member is carried by the body, while being movably mounted thereon.

Il s'agit, en pratique, d'un levier coudé monté pivotant par son coude dans ledit corps.It is, in practice, a bent lever mounted to pivot by its elbow in said body.

D'une manière générale, il est intéressant d'équiper les coupe-circuit à préhenseur de moyens, communément dits indicateurs de présence de cartouche fusible, propres à signaler l'absence éventuelle d'une telle cartouche lorsque le préhenseur est en position de fermeture.In general, it is advantageous to equip the circuit-breaker with a gripper with means, commonly called indicators of the presence of a fusible cartridge, capable of signaling the possible absence of such a cartridge when the gripper is in the closed position. .

Diverses dispositions, plus ou moins complexes, ont été proposées à cet effet; toutes, à ce jour, mettent en oeuvre des organes spécifiques.Various provisions, more or less complex, have been proposed for this purpose; all, to date, have implemented specific bodies.

La présente invention a d'une manière générale pour objet une disposition qui, au contraire, et de manière avantageusement très simple, permet de tirer parti de la présence de l'interrupteur de sectionnement pour assurer la fonction d'indication de présence de cartouche fusible recherchée.The present invention generally relates to a provision which, on the contrary, and advantageously very simple, makes it possible to take advantage of the presence of the isolating switch to perform the function of indicating the presence of a fuse cartridge wanted.

De manière plus précise, la présente invention a pour objet un coupe-circuit à préhenseur, du genre comportant dans un corps, d'une part, un organe, dit préhenseur, qui présente un évidement propre au logement d'une cartouche fusible, et qui est monté rotatif dans ledit corps entre une position de fermeture, pour laquelle ladite cartouche établit une liaison électrique entre deux contacts interposés entre deux bornes de raccordement, et une position d'extraction, pour laquelle ledit logement débouche à l'extérieur dudit corps, pour mise en place ou retrait d'une telle cartouche, et, d'autre part, un interrupteur de sectionnement interposé entre deux autres bornes de raccordement, ledit interrupteur de sectionnement étant normalement ouvert et étant susceptible d'être commandé en fermeture par le préhenseur lorsque ledit préhenseur est lui-même en position de fermeture, caractérisé en ce que, pour action sur l'interrupteur de sectionnement, le préhenseur porte un élément d'actionnement, qui est monté mobile sur ledit préhenseur entre une position déployée, pour laquelle, en présence d'une cartouche fusible, il est effectivement apte à commander en fermeture l'interrupteur de sectionnement, et une position rétractée, pour laquelle, en l'absence d'une telle cartouche fusible, il est inapte à commander en fermeture ledit interrupteur de sectionnement.More specifically, the present invention relates to a gripper circuit breaker, of the type comprising in a body, on the one hand, a member, called gripper, which has a recess specific to the housing of a fuse cartridge, and which is rotatably mounted in said body between a closed position, for which said cartridge establishes an electrical connection between two contacts interposed between two connection terminals, and an extraction position, for which said housing opens out of said body, for fitting or removing such a cartridge, and, on the other hand, a sectioning switch interposed between two other connection terminals, said sectioning switch being normally open and being capable of being closed by the gripper when said gripper is itself in the closed position, characterized in that, for action on the sectioning switch, the gripper carries an actuating element, which is movably mounted on said gripper between a deployed position, for which, in the presence of a fuse cartridge, it is effectively capable of controlling the closing switch to close, and a retracted position, for which, in the absence of 'Such a fuse cartridge, it is incapable of controlling the closing of said disconnect switch.

Par exemple, l'élément d'actionnement que porte ainsi, suivant l'invention, le préhenseur est un levier coudé, qui est monté pivotant sur ledit préhenseur, et qui présente deux bras, à savoir un premier bras apte à pénétrer dans l'évidement que présente ledit préhenseur pour logement d'une cartouche fusible, et un deuxième bras apte à commander en fermeture l'interrupteur de sectionnement associé soit directement, soit indirectement, par l'intermédiaire d'un organe intermédiaire.For example, the actuating element that thus carries, according to the invention, the gripper is a bent lever, which is pivotally mounted on said gripper, and which has two arms, namely a first arm capable of penetrating the recess that has said gripper for housing a fuse cartridge, and a second arm capable of controlling the closing of the associated disconnecting switch either directly or indirectly, via an intermediate member.

Quoi qu'il en soit, et suivant l'invention, l'élément d'actionnement que porte le préhenseur, et qui forme un organe distinct de l'organe intermédiaire décrit pour certaines formes de réalisation dans la demande de brevet français mentionnée ci-dessus, passe automatiquement en position rétractée lorsque, le préhenseur étant commandé en position de fermeture, aucune cartouche fusible ne se trouve dans l'évidement que présente ce préhenseur pour logement d'une telle cartouche fusible.Anyway, and according to the invention, the actuating element that the gripper carries, and which forms a member separate from the intermediate member described for certain embodiments in the French patent application mentioned above. above, automatically passes into the retracted position when, the gripper being controlled in the closed position, no fuse cartridge is located in the recess that this gripper has for housing such a fuse cartridge.

Dès lors, le préhenseur, bien qu'en position de fermeture, est inapte à commander en fermeture l'interrupteur de sectionnement, qui demeure ouvert.Consequently, the gripper, although in the closed position, is incapable of controlling the closing switch, which remains open.

11 suffit, pour signaler l'extérieur un tel incident, qu'un quelconque moyen de signalisation soit monté en série sur le circuit contrôlé par cet interrupteur de sectionnement.It is sufficient, to signal the outside of such an incident, that any signaling means is mounted in series on the circuit controlled by this isolation switch.

Il peut s'agir, par exemple, de la bobine d'un contacteur propre à commander un organe de signalisation, voyant ou autre.It may be, for example, the coil of a contactor capable of controlling a signaling, indicator or other device.

. Suivant un développement de l'invention, un tel contact peut, par exemple, être mis en oeuvre pour interdire la marche en monophasé de l'installation concernée lorsqu'une cartouche fusible a été malencontreusement omise dans l'un quelconque des coupe-circuit qui en contrôlent les phases. Les caractéristiques et avantages de l'invention ressortiront d'ailleurs de la description qui va suivre, à titre d'exemple, en référence aux dessins schématiques annexés sur lesquels:. According to a development of the invention, such a contact can, for example, be implemented for prohibit single-phase operation of the installation concerned when a fuse cartridge has inadvertently been omitted from any of the circuit breakers that control its phases. The characteristics and advantages of the invention will become apparent from the description which follows, by way of example, with reference to the appended schematic drawings in which:

la fig. 1 est une vue en élévation d'un coupe-circuit à préhenseur suivant l'invention, dont une partie du corps a été supposée enlevée, et dont le préhenseur a été représenté en position d'extraction, en l'absence de toute cartouche fusible;fig. 1 is an elevational view of a gripper circuit breaker according to the invention, from which a part of the body has been assumed to be removed, and from which the gripper has been shown in the extraction position, in the absence of any fusible cartridge ;

la fig. 2 est, à échelle différente, une vue partielle en perspective de ce préhenseur illustrant l'élément d'actionnement dont il est équipé suivant l'invention;fig. 2 is, on a different scale, a partial perspective view of this gripper illustrating the actuating element with which it is equipped according to the invention;

la fig. 3 est une vue analogue à celle de la fig. 1, pour une position du préhenseur intermédiaire entre sa position d'extraction et sa position de fermeture;fig. 3 is a view similar to that of FIG. 1, for a position of the intermediate gripper between its extraction position and its closed position;

la fig. 4 est une vue analogue à celle de la fig. 1, pour la position de fermeture du préhenseur;fig. 4 is a view similar to that of FIG. 1, for the closed position of the gripper;

les fig. 5 et 6 sont des vues respectivement analogues à celles des fig. 3 et 4, lorsqu'une cartouche fusible est présente dans le préhenseur.fig. 5 and 6 are views respectively similar to those of FIGS. 3 and 4, when a fuse cartridge is present in the gripper.

Sur ces figures, on reconnaît un coupe-circuit à préhenseur et interrupteur de sectionnement du type de celui décrit dans le document FR-A No 2431762 mentionné ci-dessus.In these figures, a circuit breaker with a gripper and a sectioning switch of the type described in document FR-A No. 2431762 mentioned above can be recognized.

Un tel coupe-circuit étant bien connu par lui-même et sa constitution générale ne faisant pas partie de la présente invention, il ne sera décrit ici que succinctement.Since such a circuit breaker is well known in itself and its general constitution is not part of the present invention, it will only be described here briefly.

Dans un corps 10, ou boîtier, usuellement constitué de deux coquilles, qui sont convenablement affrontées l'une à l'autre suivant un plan médian commun et convenablement assujetties l'une à l'autre ainsi affrontées, et dont une a été supposée enlevée sur les figures, est monté rotatif, ou plus précisément basculant, un organe 11, dit préhenseur, qui comporte à cet effet, latéralement, des tourillons 12 engagés à pivotement dans lesdites coquilles, et qui présente un évidement 13 propre au logement d'une cartouche fusible 14.In a body 10, or casing, usually consisting of two shells, which are suitably facing one another along a common median plane and suitably subject to each other thus faced, and one of which was assumed to be removed in the figures, is mounted a rotary, or more precisely tilting, a member 11, said gripper, which comprises for this purpose, laterally, pins 12 pivotally engaged in said shells, and which has a recess 13 suitable for housing a fuse cartridge 14.

De ce préhenseur est solidaire une manette 15 qui, à la disposition de l'usager, est propre à en permettre la manoeuvre, et qui, à cet effet, fait saillie hors du corps 10, à la faveur d'une ouverture 16 que présente en façade celui-ci; sous la commande de cette manette 15, le préhenseur 11 est rotatif dans le corps 10 entre une position extrême de fermeture, pour laquelle, tel que représenté à la fig. 6, la cartouche fusible 14, lorsqu'elle est présente, établit une liaison électrique entre deux contacts 17A, 17B interposés entre deux bornes de raccordmeent 18A, 18B, et une position d'extraction pour laquelle, tel que représenté à la fig. 1, l'évidement 13 que présente un tel préhenseur 11 pour logement d'une cartouche fusible 14 débouche à l'extérieur par l'ouverture 16 du corps 10, pour mise en place ou retrait d'une telle cartouche fusible 14 dans un tel évidement 13.A handle 15 is integral with this gripper, which, at the disposal of the user, is capable of allowing it to be maneuvered, and which, for this purpose, projects out of the body 10, by means of an opening 16 which has in front this one; under the control of this lever 15, the gripper 11 is rotatable in the body 10 between an extreme closed position, for which, as shown in FIG. 6, the fuse cartridge 14, when present, establishes an electrical connection between two contacts 17A, 17B interposed between two connection terminals 18A, 18B, and an extraction position for which, as shown in FIG. 1, the recess 13 presented by such a gripper 11 for housing a fuse cartridge 14 opens to the outside through the opening 16 of the body 10, for fitting or removing such a fuse cartridge 14 in such a obviously 13.

En pratique, et de manière connue en soi, les contacts 17A, 17B sont chacun globalement en forme de berceau, chacun de ces contacts 17A, 17B étant formé, tel qu'il est schématisé en traits interrompus à la fig. 2 pour le contact 17A, par deux lames de contact métalliques 20 élastiquement déformables, qui sont disposées globalement parallèlement l'une à l'autre dans le corps 10.In practice, and in a manner known per se, the contacts 17A, 17B are each generally in the form of a cradle, each of these contacts 17A, 17B being formed, as shown diagrammatically in broken lines in FIG. 2 for the contact 17A, by two elastically deformable metal contact blades 20, which are arranged generally parallel to one another in the body 10.

Dans son trajet de basculement entre sa position d'extraction et sa position de fermeture, le préhenseur 11 balaie l'intervalle entre les lames 20 constitutives de chacun des contacts 17A, 17B, en sorte que, lorsqu'une cartouche fusible 14 est présente dans son évidement 13, cette cartouche fusible 14 vient, par ses culots d'extrémité 21 A, 21 B, s'insérer entre les lames 20 constitutives des contacts 17A, 17B correspondants, par écartement élastique de ces lames.In its tilting path between its extraction position and its closed position, the gripper 11 scans the gap between the blades 20 constituting each of the contacts 17A, 17B, so that, when a fuse cartridge 14 is present in its recess 13, this fuse cartridge 14 comes, by its end caps 21 A, 21 B, to be inserted between the blades 20 constituting the corresponding contacts 17A, 17B, by elastic spacing of these blades.

Dans le corps 10 se trouve en outre disposé, sous le préhenseur 11, un interrupteur de sectionnement 23, qui est interposé entre deux autres bornes de raccordement 24A, 24B, distinctes des bornes de raccordement 18A, 18B précédentes; dans la forme de réalisation représentée, ces bornes de raccordement 24A, 24B sont simplement formées par les extrémités de deux lames de contact 25A, 25B, qui, encastrées dans le corps 10 à leurs dites extrémités, forment elles-mêmes l'interrupteur de sectionnement 23 à leurs autres extrémités.In the body 10 is further arranged, under the gripper 11, a sectioning switch 23, which is interposed between two other connection terminals 24A, 24B, distinct from the previous connection terminals 18A, 18B; in the embodiment shown, these connection terminals 24A, 24B are simply formed by the ends of two contact blades 25A, 25B, which, embedded in the body 10 at their said ends, themselves form the disconnection switch 23 at their other ends.

Cet interrupteur de sectionnement 23 est normalement ouvert, et il est susceptible d'être commandé en fermeture par le préhenseur 11 lorsque celui-ci est lui-même en position de fermeture.This disconnection switch 23 is normally open, and it can be ordered to close by the gripper 11 when the latter is itself in the closed position.

Dans la forme de réalisation représentée, un organe intermédiaire 25 est prévu à cet effet; disposé entre le préhenseur 11 et l'interrupteur de sectionnement 23, il est porté par le corps 10 et est monté mobile dans celui-ci.In the embodiment shown, an intermediate member 25 is provided for this purpose; disposed between the gripper 11 and the disconnection switch 23, it is carried by the body 10 and is mounted movable therein.

En pratique, dans la forme de réalisation représentée, et tel que décrit dans le document FR-A No 2431762 mentionné ci-dessus, cet organe intermédiaire 25 est constitué par un levier coudé, qui est monté pivotant par son coude dans le corps 10 et porte à cet effet latéralement des tourillons 26 engagés à pivotement dans les coquilles constitutives de celui-ci, et qui présente deux bras, chacun respectivement disposé de part et d'autre de son coude, à savoir un bras 27, sur lequel le préhenseur 11 est susceptible d'agir lorsqu'il est en position de fermeture, et un bras 28, par lequel il est lui-même apte à agir sur l'interrupteur de sectionnement 23 pour le commander en position de fermeture.In practice, in the embodiment shown, and as described in the document FR-A No 2431762 mentioned above, this intermediate member 25 is constituted by a bent lever, which is pivotally mounted by its elbow in the body 10 and for this purpose laterally carries pins 26 pivotally engaged in the shells constituting the latter, and which has two arms, each respectively disposed on either side of its elbow, namely an arm 27, on which the gripper 11 is capable of acting when it is in the closed position, and an arm 28, by which it is itself capable of acting on the isolating switch 23 to control it in the closed position.

Enfin, extérieurement, le corps 10 présente une semelle 29, propre à son assujettissemennt à un quelconque rail de support, par exemple à l'aide d'un verrou 30 monté mobile à l'encontre d'un ressort de rappel 31.Finally, externally, the body 10 has a sole 29, suitable for being subject to any support rail, for example using a lock 30 mounted movably against a return spring 31.

Suivant l'invention, pour action sur l'interrupteur de sectionnement 23, le préhenseur 11 porte un élément d'actionnement 33, qui est monté mobile sur ledit préhenseur 11, entre une position déployée, pour laquelle, en présence d'une cartouche fusible 14, et comme représenté à la fig. 6, il est effectivement apte à commander en fermeture l'interrupteur de sectionnement 23, suivant des dispositions détaillées ci-après, et une position rétractée, pour laquelle, en l'absence d'une telle cartouche fusible 14, et comme représenté sur la fig. 4, il est inapte à commander en fermeture ledit interrupteur de sectionnement 23.According to the invention, for action on the sectioning switch 23, the gripper 11 carries an actuating element 33, which is movably mounted on said gripper 11, between a deployed position, for which, in the presence of a fuse cartridge 14, and as shown in FIG. 6, it is effectively able to order in closing the disconnection switch 23, according to the arrangements detailed below, and a retracted position, for which, in the absence of such a fuse cartridge 14, and as shown in FIG. 4, it is incapable of controlling said sectioning switch 23 to close.

Dans la forme de réalisation représentée, l'élément d'actionnement 33 que porte ainsi le préhenseur 11 forme un levier coudé, qui, par son coude, est monté librement pivotant, à frottement, sur le préhenseur 11, et qui présente deux bras 34, 35 s'étendant chacun respectivement de part et d'autre de son coude, à savoir un premier bras 34 apte à pénétrer dans l'évidement 13 que présente le préhenseur 11 pour logement d'une cartouche fusible 14, et un deuxième bras 35 apte à commander en fermeture l'interrupteur de sectionnement 23.In the embodiment shown, the actuating element 33 thus carried by the gripper 11 forms a bent lever, which, by its elbow, is mounted to pivot freely, frictionally, on the gripper 11, and which has two arms 34 , 35 each extending respectively on either side of its elbow, namely a first arm 34 able to penetrate into the recess 13 presented by the gripper 11 for housing a fuse cartridge 14, and a second arm 35 suitable for controlling the closing switch 23.

En pratique, dans la forme de réalisation représentée, l'élément de sectionnement 33 constitue, pour le préhenseur 11, un nez disposé dans une région de celui-ci dont le trajet balaie l'intervalle entre les lames 20 constitutives du contact 17A, qui est celui destiné à coopérer avec le culot 21 A immédiatement accessible de la cartouche fusible 14 lorsque le préhenseur 11 est en position d'extraction.In practice, in the embodiment shown, the cutting element 33 constitutes, for the gripper 11, a nose disposed in a region thereof, the path of which sweeps the gap between the blades 20 constituting the contact 17A, which is that intended to cooperate with the base 21 A immediately accessible from the fuse cartridge 14 when the gripper 11 is in the extraction position.

La région en question du préhenseur 11 est donc formée par celle des extrémités du bord de l'évidement 13 le plus éloigné de la manette 15 qui est la plus proche de l'ouverture 16 du corps 10 lorsque le préhenseur 11 est en position d'extraction.The region in question of the gripper 11 is therefore formed by that of the ends of the edge of the recess 13 furthest from the lever 15 which is closest to the opening 16 of the body 10 when the gripper 11 is in the position of extraction.

En pratique, dans la forme de réalisation représentée, le préhenseur 11 présente transversalement, à l'extrémité en question, un épaulement 36 sur la zone médiane duquel fait saillie une oreille 37, et le levier constituant l'élément d'actionnement 33 forme globalement une chape 38 par laquelle il est engagé sur cette oreille 37, un axe de pivotement 39 traversant transversalement ladite chape et ladite oreille.In practice, in the embodiment shown, the gripper 11 has transversely, at the end in question, a shoulder 36 on the median zone from which protrudes an ear 37, and the lever constituting the actuating element 33 forms overall a yoke 38 by which it is engaged on this ear 37, a pivot axis 39 transversely passing through said yoke and said ear.

Chacun des bras 34, 35 de ce levier est donc constitué par deux éléments de bras parallèles, disposés chacun respectivement de part et d'autre de l'oreille 37 sur laquelle ils sont articulés.Each of the arms 34, 35 of this lever therefore consists of two parallel arm elements, each arranged respectively on either side of the lug 37 on which they are articulated.

A leur extrémité, les deux éléments de bras constituant ainsi le bras 34 du levier 33 forment conjointement une traverse commune 40.At their end, the two arm elements thus constituting the arm 34 of the lever 33 jointly form a common crosspiece 40.

Ainsi qu'il est aisé de le comprendre, l'épaulement 36 du préhenseur 11 est apte à définir l'une au moins des positions, déployée ou rétractée, de l'élément d'actionnement 33, et, en pratique, par appui de l'un ou de l'autre des bras du levier constituant cet élément d'actionnement 33, il est apte, dans la forme de réalisation représentée, à définir l'une et l'autre des positions, déployée et rétractée, de celui-ci.As is easy to understand, the shoulder 36 of the gripper 11 is capable of defining at least one of the positions, deployed or retracted, of the actuating element 33, and, in practice, by pressing one or the other of the arms of the lever constituting this actuating element 33, it is capable, in the embodiment shown, of defining one and the other of the positions, deployed and retracted, of this- this.

Pour un tel appui, le bras 34 porte, dans la forme de réalisation représentée, un bossage arrondi 41.For such support, the arm 34 carries, in the embodiment shown, a rounded boss 41.

Quoi qu'il en soit, et suivant l'invention, l'élément d'actionnement 33 a transversalement une largeur L1 légèrement supérieure à celle L2 de l'intervalle entre les lames 20 constitutives du contact 17A lorsque celles-ci sont au repos (fig.2).Anyway, and according to the invention, the actuating element 33 has transversely a width L1 slightly greater than that L2 of the gap between the blades 20 constituting the contact 17A when these are at rest ( fig. 2).

En outre, suivant l'invention, un organe intermédiaire 25 étant présent, le trajet balayé par l'élément d'actionnement 33 que porte le préhenseur 11 lorsque celui-ci passe de sa position d'extraction à sa position de fermeture interfère avec ledit organe auxiliaire 25 lorsque ledit élément d'actionnement est en position déployée, et seulement dans un tel cas.Furthermore, according to the invention, an intermediate member 25 being present, the path swept by the actuating element 33 carried by the gripper 11 when the latter passes from its extraction position to its closed position interferes with said auxiliary member 25 when said actuating element is in the deployed position, and only in such a case.

On supposera, tout d'abord, en référence aux fig. 1 à 4, qu'aucune cartouche fusible n'est présente dans l'évidement 13 du préhenseur 11.We will suppose, first of all, with reference to figs. 1 to 4, that no fuse cartridge is present in the recess 13 of the gripper 11.

Lorsque, suivant la flèche F1 de la fig. 1, le préhenseur 11 est basculé de sa position d'extraction représentée à la fig. 1 à sa position de fermeture représentée à la fig. 4, l'élément d'actionnement 33 qu'il porte - qui, pour la position d'extraction, est à distance du contact 17A, au-dessus de celui-ci, et qui, pour des raisons qui apparaîtront ci-après, et par frottement, occupe alors lui-même sa position déployée, son bras 35 portant librement contre l'épaulement 36 du préhenseur 11 - vient, dans un premier temps, entrer en prise, par ledit bras 35, avec les lames 20 constitutives dudit contact 17A (fig. 3).When, according to the arrow F1 of FIG. 1, the gripper 11 is tilted from its extraction position shown in FIG. 1 in its closed position shown in FIG. 4, the actuating element 33 which it carries - which, for the extraction position, is at a distance from the contact 17A, above the latter, and which, for reasons which will appear below, and by friction, then occupies itself in its deployed position, its arm 35 bearing freely against the shoulder 36 of the gripper 11 - comes, first, to engage, by said arm 35, with the blades 20 constituting said contact 17A (fig. 3).

Etant de largeur supérieure à l'intervalle séparant ces lames, il doit provoquer un écartement élastique de celles-ci, et, en retour, il est l'objet de la part de ces lames, par un effet de freinage, d'une action qui, comme schématisé par la flèche F2 sur les fig. 1 et 3, et comme représenté sur cette fig. 3, le conduit à basculer en position rétractée.Being of width greater than the interval separating these blades, it must cause an elastic spacing of these, and, in return, it is the object on the part of these blades, by a braking effect, of an action which, as shown diagrammatically by the arrow F2 in FIGS. 1 and 3, and as shown in this fig. 3, the duct to switch to the retracted position.

Pour cette position rétractée, qui est maintenue par frottement, le bras 34 de l'élément d'actionnement 33 pénètre largement dans l'évidement 13 du préhenseur 11, jusqu'à porter par son bossage 41 contre l'épaulement 36 de celui-ci.For this retracted position, which is held by friction, the arm 34 of the actuating element 33 penetrates widely into the recess 13 of the gripper 11, until carried by its boss 41 against the shoulder 36 thereof .

Mais, conjointement, le bras 35 de l'élément d'actionnement 33 occupe alors une position suffisamment effacée pour ne pas interférer avec l'organe auxiliaire 25, comme représenté à la fig. 4.However, jointly, the arm 35 of the actuating element 33 then occupies a position which is sufficiently obliterated not to interfere with the auxiliary member 25, as shown in FIG. 4.

Dès lors, et bien que le préhenseur 11 soit en position de fermeture, l'interrupteur de sectionnement 23 n'est pas commandé en fermeture.Therefore, and although the gripper 11 is in the closed position, the sectioning switch 23 is not controlled in closing.

Lorsque, suivant un mouvement de basculement inverse de celui repéré par la flèche F1 à la fig. 1, le préhenseur 11 est commandé en basculement de sa position de fermeture à sa position d'extraction, l'élément d'actionnement 33 qu'il porte est, par un effet inverse du précédent, ramené en position déployée au passage entre les lames 20 constitutives du contact 17A, et maintenu dans cette position déployée par frottement.When, following a reverse tilting movement from that identified by the arrow F1 in FIG. 1, the gripper 11 is controlled in tilting from its closed position to its extraction position, the actuating element 33 which it carries is, by an effect opposite to the previous one, brought back to the deployed position when passing between the blades 20 constituting the contact 17A, and maintained in this deployed position by friction.

On supposera, maintenant, qu'une cartouche fusible 14 est présente dans l'évidement 13 du préhenseur 11.We will now assume that a fuse cartridge 14 is present in the recess 13 of the gripper 11.

Lorsque, comme précédemment, celui-ci est commandé en basculement de sa position d'extraction à sa position de fermeture, l'élément d'actionnement 33 qu'il porte est empêché par ladite cartouche fusible 14 de basculer en position rétractée, son bras 34 venant porter contre cette cartouche fusible 14 (fig. 5).When, as before, the latter is controlled in tilting from its extraction position to its closed position, the actuating element 33 which it carries is prevented by said fuse cartridge 14 from tilting in the retracted position, its arm 34 coming to bear against this fuse cartridge 14 (fig. 5).

Par suite, lorsque le préhenseur 11 est en position de fermeture, l'élément d'actionnement 33 qu'il porte est toujours en position déployée, en sorte que, par son bras 35, il vient agir sur l'organe intermédiaire 25 et, par lui, commander en fermeture l'interrupteur de sectionnement 23.Consequently, when the gripper 11 is in closed position, the actuating element 33 which it carries is always in the deployed position, so that, by its arm 35, it acts on the intermediate member 25 and, by means of it, commands the switch to close sectioning 23.

En pratique, dans l'exemple de réalisation représenté, l'élément d'actionnement 33 vient porter, par son bras 35, sur le bras 27 de l'organe intermédiaire 25 et provoquer ainsi le basculement de celui-ci.In practice, in the embodiment shown, the actuating element 33 comes to bear, by its arm 35, on the arm 27 of the intermediate member 25 and thus cause the latter to tilt.

Cet organe intermédiaire 25, étant disposé au-dessus de la lame 25A de l'interrupteur de sectionnement 23 constituant la lame de contact mobile de celui-ci, provoque, par son bras 28, une déformation élastique de cette lame 25A de nature à venir la faire porter sur la lame 24B associée.This intermediate member 25, being disposed above the blade 25A of the isolating switch 23 constituting the movable contact blade thereof, causes, by its arm 28, an elastic deformation of this blade 25A of a nature to come bring it to bear on the associated blade 24B.

Suivant l'invention, le maintien en position d'ouverture de l'interrupteur de sectionnement 23 lorsque, le préhenseur 11 étant en position de fermeture, aucune cartouche fusible n'est présente dans son évidement, est mis à profit, par l'élément d'actionnement 33, pour signaler une telle absence.According to the invention, the maintenance in the open position of the disconnection switch 23 when, the gripper 11 being in the closed position, no fuse cartridge is present in its recess, is taken advantage of, by the element actuation 33, to signal such an absence.

Il suffit, à cet effet, d'insérer en série avec l'interrupteur de sectionnement 23 un quelconque moyen de signalisation ou un quelconque organe propre à commander un tel moyen de signalisation.For this purpose, it suffices to insert in series with the disconnection switch 23 any signaling means or any member suitable for controlling such signaling means.

Il peut s'agir de la bobine d'un contacteur.It can be the coil of a contactor.

En outre, comme mentionné ci-dessus, un tel contacteur peut être utilisé pour interdire un fonctionnement en monophasé.In addition, as mentioned above, such a contactor can be used to prohibit single-phase operation.

Ainsi qu'on l'aura noté, le fait que, au retour du préhenseur 11 en position d'extraction, l'élément d'actionnement 33 porté par celui-ci revienne systématiquement, comme décrit ci-dessus, en position rétractée, lorsque aucune cartouche fusible 14 n'est présente dans l'évidement 13 du préhenseur 11, est particulièrement avantageux, puisque ledit évidement 13 est alors directement accessible et qu'aucune action particulière n'est ainsi à exercer sur l'élément d'actionnement 33 pour pouvoir y mettre en place une cartouche fusible 14.As will have been noted, the fact that, on returning from the gripper 11 in the extraction position, the actuating element 33 carried by the latter systematically returns, as described above, to the retracted position, when no fuse cartridge 14 is present in the recess 13 of the gripper 11, is particularly advantageous, since said recess 13 is then directly accessible and that no particular action is thus to be exerted on the actuating element 33 to ability to install fuse cartridge 14.

Au lieu d'être monté pivotant sur le préhenseur 11, l'élément d'actionnement porté suivant l'invention par celui-ci pourrait être monté coulissant sur un tel préhenseur.Instead of being pivotally mounted on the gripper 11, the actuating element carried according to the invention by the latter could be slidably mounted on such a gripper.

En outre, la réalisation pratique de l'interrupteur de sectionnement mis en oeuvre est quelconque.In addition, the practical implementation of the disconnect switch used is arbitrary.

Par exemple, un tel interrupteur de sectionnement peut comporter des grains de contact, en argent ou autre, et/ou comporter un renfort constitué par une lame-ressort doublant sa lame de contact mobile sur une partie de la longueur de celle-ci et encastrée avec elle dans le corps du coupe-circuit.For example, such a disconnection switch may include contact grains, in silver or other, and / or comprise a reinforcement constituted by a leaf spring doubling its movable contact blade over a part of its length and embedded with it in the body of the circuit breaker.

En variante, au lieu d'être encastrée, cette lame de contact mobile pourrait être libre, entre deux lames fixes, encastrées ou non, à relier.Alternatively, instead of being embedded, this movable contact blade could be free, between two fixed blades, embedded or not, to be connected.

Par ailleurs, le domaine d'application de l'invention n'est pas limité au cas où le préhenseur 11 est apte à agir sur un interrupteur de sectionnement par l'intermédiaire d'un organe intermédiaire.Furthermore, the field of application of the invention is not limited to the case where the gripper 11 is able to act on a sectioning switch by means of an intermediate member.

Au contraire, et comme décrit notamment dans certaines des formes de réalisation représentées dans le document FR-A No 2431762 mentionné ci-dessus, tout organe intermédiaire peut être éliminé.On the contrary, and as described in particular in some of the embodiments shown in the document FR-A No 2431762 mentioned above, any intermediate member can be eliminated.

En outre, lorsqu'un tel organe intermédiaire est présent, il ne s'agit pas nécessairement d'un levier pivotant.In addition, when such an intermediate member is present, it is not necessarily a pivoting lever.

Il peut au contraire aussi bien s'agir, par exemple, d'un tiroir monté coulissant.On the contrary, it may also be, for example, a sliding mounted drawer.
