Un tel système permet de personnaliser aisément le disjoncteur en lui ajoutant des fonctions supplémentaires. La fonction remplie par le bloc auxiliaire est par exemple une fonction de signalisation, dans laquelle le bloc auxiliaire est apte à communiquer à un dispositif électronique distant l'état (ouvert ou fermé) du disjoncteur.We know of the document EP 0 591 074 A1 a circuit breaker comprising an outer casing having a plurality of housings each capable of receiving an auxiliary block. Each auxiliary block is then removable relative to the outer envelope. Each of the receiving slots has electrical terminals adapted to be connected to an auxiliary unit received in the housing. Such a system makes it easy to customize the circuit breaker by adding additional functions. The function performed by the auxiliary unit is for example a signaling function, in which the auxiliary unit is able to communicate to a remote electronic device the state (open or closed) of the circuit breaker.

Il est nécessaire pour des raisons de sécurité d'empêcher l'accès aux logements de réception depuis l'extérieur de l'enveloppe dans des conditions normales de fonctionnement du disjoncteur. Pour cela, l'enveloppe externe comporte un socle et un couvercle apte à coopérer pour former une enveloppe fermée entourant les logements de réception et les blocs auxiliaires et pour les isoler ainsi électriquement de l'extérieur.It is necessary for security reasons to prevent access to the receiving slots from outside the enclosure under normal circuit breaker operating conditions. For this, the outer envelope comprises a base and a cover adapted to cooperate to form a closed envelope surrounding the receiving housing and the auxiliary units and thus electrically isolate them from the outside.

Un tel couvercle rend également les logements de réception et les éventuels blocs auxiliaires invisibles depuis l'extérieur. La présence d'un ou de plusieurs blocs auxiliaires dans le disjoncteur doit alors être signalée par l'apposition d'une ou plusieurs vignettes autocollantes contre une face externe de l'enveloppe du disjoncteur. Ces vignettes portent des informations relatives au type et/ou à la position des blocs auxiliaires utilisés. Les vignettes sont mises en place, respectivement retirées, par l'opérateur lors de la mise en place, respectivement lors du retrait, d'un ou plusieurs blocs auxiliaires.Such a cover also makes the receiving housing and any auxiliary blocks invisible from the outside. The presence of one or more auxiliary units in the circuit-breaker must then be indicated by the affixing of one or more self-adhesive stickers against an outer face of the circuit-breaker enclosure. These thumbnails carry information relating to the type and / or position of the auxiliary blocks used. The thumbnails are set up, respectively removed, by the operator during the introduction, respectively during the withdrawal, of one or more auxiliary blocks.

Cependant, bien que la mise en place des vignettes autocollantes soit une opération simple en soi, elle est également source d'erreurs. Il faut une grande rigueur pour que tous les disjoncteurs d'un réseau soient équipés chacun des vignettes correspondant aux blocs auxiliaires qu'il comporte. Il est également nécessaire, lors de chaque modification de configuration des blocs auxiliaires du disjoncteur, de mettre à jour l'information portée par les vignettes. De plus, lors de la vie d'un disjoncteur, il peut arriver que les vignettes soient endommagées, rendues illisibles ou se décollent. Il est donc souvent nécessaire d'ouvrir le couvercle de l'enveloppe externe afin de vérifier si des blocs auxiliaires sont présents, et le cas échéant quelle est leur type. Pour des raisons de sécurité, une telle opération ne peut être effectuée que par un opérateur habilité à ouvrir l'enveloppe, et nécessite souvent la mise hors circuit du dispositif de commutation.However, although the placement of self-adhesive stickers is a simple operation in itself, it is also a source of error. It is necessary to be very rigorous so that all the circuit breakers of a network are equipped each with the thumbnails corresponding to the auxiliary blocks which it comprises. It is also necessary, during each configuration change of the auxiliary blocks of the circuit breaker, to update the information carried by the thumbnails. Moreover, during the life of a circuit breaker, it can happen that the stickers are damaged, rendered illegible or peeled off. It is therefore often necessary to open the cover of the outer envelope to check if auxiliary blocks are present, and if so what is their type. For security reasons, such an operation can only be performed by an operator authorized to open the envelope, and often requires the switching device to be switched off.

Le but de l'invention est de proposer un dispositif de commutation électrique muni d'au moins un bloc auxiliaire amovible, permettant une signalisation efficace et pérenne de la présence d'un ou plusieurs blocs auxiliaires. L'invention a également pour but de limiter les procédures à la charge de l'opérateur qui personnalise le dispositif de commutation électrique et de minimiser le risque d'erreurs humaines.The object of the invention is to propose an electrical switching device provided with at least one removable auxiliary block, allowing an effective and lasting signaling of the presence of one or more auxiliary blocks.

Sur les figures 1 et 2, le dispositif de commutation 2 comporte un bloc de commutation 4, deux blocs auxiliaires 6 et un bloc déclencheur 7, le bloc déclencheur 7 étant visible seulement sur la figure 2. Sur la figure 2, le dispositif de commutation 2 comporte également des bornes d'entrée 8, des bornes de sortie 10 et une enveloppe externe 12.On the figures 1 and 2 , the switching device 2 comprises a switching block 4, two auxiliary blocks 6 and a trigger block 7, the trigger block 7 being visible only on the figure 2 . On the figure 2 the switching device 2 also has input terminals 8, output terminals 10 and an outer envelope 12.

Le dispositif de commutation 2 est apte à recevoir un courant d'entrée I sur les bornes d'entrée 8 et à le délivrer sur les bornes de sortie 10, et vice-versa. Sur la figure 1, le dispositif de commutation 2 est un disjoncteur triphasé.The switching device 2 is adapted to receive an input current I on the input terminals 8 and to deliver it to the output terminals 10, and vice versa. On the figure 1 , the switching device 2 is a three-phase circuit breaker.

Le bloc de commutation 4 comprend au moins un logement 14 de réception de bloc auxiliaire, chaque logement de réception 14 étant configuré pour recevoir un bloc auxiliaire 6 respectif. Dans l'exemple de réalisation décrit, le bloc de commutation 4 comprend deux logements de réception 14. Le bloc de commutation 4 est apte à couper la transmission du courant d'entrée I entre les bornes d'entrée 8 et les bornes de sortie 10.The switching block 4 comprises at least one auxiliary block receiving housing 14, each receiving housing 14 being configured to receive a respective auxiliary block 6. In the embodiment described, the switching unit 4 comprises two receiving slots 14. The switching block 4 is able to cut off the transmission of the input current I between the input terminals 8 and the output terminals 10 .

Le bloc de commutation 4 est connu en soi. Le bloc de commutation 4 est par exemple un bloc de commutation électromécanique.The switching block 4 is known per se. The switching block 4 is for example an electromechanical switching block.

Dans l'exemple de la figure 1, les blocs auxiliaires 6 comportent des bornes auxiliaires 16, des faces latérales 18, une face d'actionnement mécanique 20, une première face d'extrémité 22, une deuxième face d'extrémité 24 et une face de connexion 26 portant les bornes auxiliaires 16.In the example of the figure 1 the auxiliary units 6 comprise auxiliary terminals 16, side faces 18, a mechanical operating face 20, a first end face 22, a second end face 24 and a connection face 26 carrying the auxiliary terminals 16 .

Sur la figure 1, chaque bloc auxiliaire 6 porte une nervure 28 de guidage dans le logement 14 et des moyens 30 d'attache dans le logement 14.On the figure 1 each auxiliary block 6 carries a guide rib 28 in the housing 14 and attachment means 30 in the housing 14.

Selon l'exemple de la figure 1, les blocs auxiliaires 6 sont introduits dans le logement 14 par un mouvement de translation selon une direction verticale d'introduction.According to the example of the figure 1 , the auxiliary blocks 6 are introduced into the housing 14 by a translational movement in a vertical direction of introduction.

Les blocs auxiliaires 6 sont configurés pour réaliser au moins une fonction auxiliaire du dispositif de commutation 2.The auxiliary units 6 are configured to perform at least one auxiliary function of the switching device 2.

La fonction auxiliaire est par exemple une fonction de signalisation de l'état du dispositif de commutation 2. Dans le cas où le dispositif de commutation 2 est un disjoncteur, le bloc auxiliaire 6 est alors apte à générer un signal électrique d'état représentatif de l'état ouvert ou fermé du disjoncteur 2 et à délivrer le signal d'état sur les bornes auxiliaires 16.The auxiliary function is for example a signaling function of the state of the switching device 2. In the case where the switching device 2 is a circuit breaker, the auxiliary block 6 is then able to generate a state electrical signal representative of the open or closed state of the circuit-breaker 2 and to deliver the state signal on the auxiliary terminals 16.

En variante, la fonction auxiliaire est une fonction de signalisation d'un déclenchement sur défaut. Dans ce cas, le bloc auxiliaire 6 est apte à générer un signal électrique de déclenchement si le bloc de commutation 4 a coupé le courant I après détection d'un défaut.In a variant, the auxiliary function is a function for signaling a fault trip. In this case, the auxiliary unit 6 is able to generate an electrical trip signal if the switching block 4 has cut the current I after detection of a fault.

Dans l'exemple de la figure 1, les blocs auxiliaires 6 sont normalisés, et chaque logement de réception 14 est associé à une fonction spécifique. Dans ce cas, la mise en place d'un bloc auxiliaire 6 dans un premier logement 14 donnera au bloc auxiliaire 6 une première fonction. Par exemple, la première fonction est une fonction de signalisation de l'état du dispositif de commutation. La mise en place du même bloc auxiliaire 6 dans un deuxième logement 14 donnera au bloc auxiliaire 6 une deuxième fonction. Par exemple, la deuxième fonction est une fonction de signalisation d'un déclenchement sur défaut.In the example of the figure 1 the auxiliary blocks 6 are normalized, and each receiving slot 14 is associated with a specific function. In this case, the establishment of an auxiliary block 6 in a first housing 14 will give the auxiliary block 6 a first function. For example, the first function is a signaling function of the state of the switching device. Placing the same auxiliary unit 6 in a second housing 14 will give the auxiliary unit 6 a second function. For example, the second function is a signaling function of a fault trigger.

Selon un autre mode de réalisation, non représenté, le bloc auxiliaire 6 a une fonction qui lui est propre. Par exemple, chaque type de blocs auxiliaires 6 présente des dimensions différentes de celles des autres types de blocs auxiliaires 6.According to another embodiment, not shown, the auxiliary block 6 has a function of its own.

Chaque creux de guidage 42 comporte par exemple une gorge 58 apte à recevoir la nervure de guidage 28 correspondante.The guiding cavities 42 are capable of guiding the auxiliary blocks 6 when they are placed in position in their housing 14. Each guiding cavity 42 comprises, for example, a groove 58 able to receive the corresponding guiding rib 28.

Chaque élément d'attache 44 est apte à maintenir le bloc auxiliaire 6 correspondant en position dans le logement de réception 14 correspondant. Selon la figure 1, chaque élément d'attache 30 comporte des ergots 60 aptes à collaborer avec les moyens élastiques d'attache 30 par encliquetage pour empêcher le retrait inopiné du bloc auxiliaire 6 hors du logement 14. Les ergots 60 sont par exemple venus de matière avec la plaque latérale 32 de l'enveloppe 12.Each attachment element 44 is able to hold the corresponding auxiliary block 6 in position in the corresponding receiving housing 14. According to figure 1 each fastening element 30 has lugs 60 capable of collaborating with the resilient fastening means 30 by snap-fastening to prevent the auxiliary block 6 from being withdrawn out of the housing 14. The lugs 60 are, for example, integral with the plate lateral 32 of the envelope 12.

Les pivots 46 sont par exemple des projections cylindriques venues de matière avec le couvercle 36.The pivots 46 are for example cylindrical projections integral with the cover 36.

Les moyens de signalisation 48 sont mobiles en translation selon une direction de translation entre la position inactive et la position active de signalisation. La direction de translation est de préférence parallèle à la face interne 56 du couvercle 36. La direction de translation est de préférence encore parallèle à une direction longitudinale du dispositif de commutation 2. La direction longitudinale du dispositif de commutation 2 est la direction selon laquelle le dispositif de commutation 2 s'étend, c'est-à-dire la direction selon laquelle il présente sa plus grande longueur.The signaling means 48 are movable in translation in a direction of translation between the inactive position and the active signaling position. The translation direction is preferably parallel to the inner face 56 of the cover 36. The translation direction is preferably still parallel to a longitudinal direction of the switching device 2. The longitudinal direction of the switching device 2 is the direction in which the switching device 2 extends, that is to say the direction in which it has its greatest length.

Dans un autre mode de réalisation, non représenté, les moyens de signalisation sont mobiles en rotation autour d'un axe. Par exemple, l'axe de rotation des moyens de signalisation 48 est perpendiculaire à la face interne 56 du couvercle 36.In another embodiment, not shown, the signaling means are rotatable about an axis. For example, the axis of rotation of the signaling means 48 is perpendicular to the inner face 56 of the cover 36.

Les moyens de signalisation 48 comportent, par exemple, un organe de signalisation 61 pour chaque logement de réception 14. Dans l'exemple de la figure 4, les moyens de signalisation 48 comportent alors deux organes de signalisation 61. Chaque organe de signalisation 61 est mobile entre la position inactive de signalisation et la position active de signalisation indiquant la présence d'un bloc auxiliaire respectif 6 dans le logement de réception correspondant 14. En variante non représentée, les moyens de signalisation 48 sont mobiles entre une position inactive de signalisation et au moins deux positions actives de signalisation. Chaque position active de signalisation indique par exemple la présence d'un type spécifique de bloc de signalisation 6, la position active étant alors par exemple variable en fonction de l'encombrement du bloc auxiliaire 6, c'est-à-dire en fonction de ses dimensions externes.The signaling means 48 comprise, for example, a signaling element 61 for each receiving housing 14. In the example of FIG. figure 4 , the signaling means 48 then comprise two signaling members 61. signaling member 61 is movable between the inactive signaling position and the active signaling position indicating the presence of a respective auxiliary block 6 in the corresponding receiving housing 14. As a variant not shown, the signaling means 48 are movable between a inactive signaling position and at least two active signaling positions. Each active signaling position for example indicates the presence of a specific type of signal block 6, the active position then being for example variable depending on the size of the auxiliary block 6, that is to say as a function of its external dimensions.

Sur les figures 2 et 4, chaque organe de signalisation 61 est en forme d'une languette 62 qui s'étend sensiblement parallèlement à la face interne 56 du couvercle 36 et est apte à coopérer avec une glissière 64 du couvercle. Chaque organe de signalisation 61 comporte au moins un index de signalisation 66. L'index de signalisation 66 est visible à travers la fenêtre de visualisation 54 lorsque l'organe de signalisation 61 correspondant est dans sa position active.On the figures 2 and 4 , each signaling member 61 is in the form of a tongue 62 which extends substantially parallel to the inner face 56 of the cover 36 and is adapted to cooperate with a slide 64 of the cover. Each signaling member 61 comprises at least one signaling index 66. The signaling index 66 is visible through the viewing window 54 when the corresponding signaling member 61 is in its active position.

Sur les figures 4 et 5, les moyens de maintien 50 comprennent au moins une saillie élastique 68 de maintien, portée par chaque languette 62 et au moins une cavité de retenue 70, davantage visible sur la figure 5. Une deuxième cavité de retenue 71 est apte à collaborer avec la saillie de maintien 68 pour maintenir l'organe de signalisation 61 correspondant en position active.On the figures 4 and 5 , the holding means 50 comprise at least one elastic protrusion 68 for holding, carried by each tongue 62 and at least one retaining cavity 70, more visible on the figure 5 . A second retaining cavity 71 is able to collaborate with the retaining projection 68 to keep the corresponding signaling member 61 in the active position.

Chaque ergot de retenue 51 est en outre apte à maintenir la languette 62 plaquée contre la face interne 56 du couvercle. Chaque ergot de retenue 51 permet donc de solidariser l'organe de signalisation 61 correspondant et le couvercle 36. Dans l'exemple de réalisation décrit, l'association de chaque ergot de retenue 51 et de chaque glissière 64 empêche l'organe de signalisation 61 correspondant de se déplacer autrement que par translation dans la direction de signalisation.Each retaining pin 51 is further adapted to hold the tongue 62 pressed against the inner face 56 of the lid. Each retaining lug 51 thus makes it possible to secure the corresponding signaling member 61 and the cover 36. In the embodiment described, the combination of each retaining pin 51 and of each slideway 64 prevents the signaling member 61 corresponding to move otherwise than by translation in the signaling direction.

Selon l'exemple de la figure 6, les moyens de commande 52 comprennent une came 72 pour chaque logement de réception 14, chaque came 72 étant solidaire d'un organe de signalisation 61 respectif. Chaque came 72 est configurée pour coopérer, lors de la fermeture du couvercle 36, avec un bloc auxiliaire 6 présent dans le logement de réception 14 associé afin de déplacer l'organe de signalisation 61 correspondant de la position inactive jusqu'à la position active.According to the example of the figure 6 , the control means 52 comprise a cam 72 for each receiving housing 14, each cam 72 being secured to a respective signaling member 61. Each cam 72 is configured to cooperate, when closing the cover 36, with an auxiliary unit 6 present in the associated receiving housing 14 in order to move the corresponding signaling member 61 from the inactive position to the active position.

Les moyens de commande 52 comprennent en outre une butée 74 d'arrêt. Les moyens de commande 52 sont par exemple venus de matière avec la languette 62.The control means 52 further comprises a stop 74. The control means 52 are for example integral with the tongue 62.

Dans le cas où plusieurs types de blocs auxiliaires 6 (de dimensions différentes ou identiques) sont insérés dans le logement 14, les moyens de commande 52 sont aptes à collaborer avec chaque bloc auxiliaire 6 pour déplacer les moyens de signalisation 48 dans une position active de signalisation correspondante. Chaque organe de signalisation 61 est, par exemple, configuré pour coopérer avec un bloc auxiliaire 6 respectif.In the case where several types of auxiliary blocks 6 (of different or identical dimensions) are inserted in the housing 14, the control means 52 are able to collaborating with each auxiliary block 6 to move the signaling means 48 to a corresponding signaling active position. Each signaling member 61 is, for example, configured to cooperate with a respective auxiliary block 6.

Les fenêtres 54 sont par exemple en forme d'ouvertures traversantes ménagées dans le couvercle 36. En complément facultatif, les fenêtres 54 comprennent une pièce transparente (non représentée) configurée pour obturer l'ouverture correspondante tout en permettant à un opérateur de distinguer l'index de visualisation 66 lorsque les moyens de signalisation sont en position active de signalisation.The windows 54 are for example in the form of through openings formed in the cover 36. In addition, the windows 54 optionally comprise a transparent piece (not shown) configured to close the corresponding opening while allowing an operator to distinguish the display index 66 when the signaling means are in the active signaling position.

La face interne 56 du couvercle 36 comporte une cavité 76 parallélépipédique munie de quatre faces internes 78.The inner face 56 of the cover 36 has a parallelepipedal cavity 76 provided with four internal faces 78.

La languette 62 est configurée pour s'interposer entre la face d'obturation 57 et la fenêtre 54 du couvercle lorsque l'organe de signalisation 61 correspondant est dans sa position active. La languette 62 est configurée pour s'intercaler entre l'ergot de retenue 51 et la face interne 56 du couvercle 36. La languette 62 est en contact avec la face interne 56 du couvercle 36. La languette 62 porte l'index de signalisation 66.The tongue 62 is configured to interpose between the sealing face 57 and the window 54 of the cover when the corresponding signaling member 61 is in its active position. The tongue 62 is configured to be interposed between the retaining pin 51 and the inner face 56 of the lid 36. The tongue 62 is in contact with the inner face 56 of the lid 36. The tongue 62 carries the signaling index 66 .

En variante non représentée, la languette 62 comprend une pluralité d'index de signalisation 66. Chaque index de signalisation 66 correspond à une position active de signalisation. Chaque index de visualisation 66 est visible à travers la fenêtre de visualisation 54 lorsque les moyens de signalisation 48 sont dans une position active de signalisation correspondante.In a variant not shown, the tongue 62 comprises a plurality of signaling indexes 66. Each signaling index 66 corresponds to an active signaling position. Each display index 66 is visible through the viewing window 54 when the signaling means 48 are in a corresponding signaling active position.

Chaque glissière 64 est apte à recevoir un organe de signalisation 61 correspondant. Chaque glissière 64 est apte à guider l'organe de signalisation 61 correspondant en translation dans la direction de signalisation entre la position inactive et la ou les positions actives de signalisation.Each slide 64 is able to receive a corresponding signaling member 61. Each slideway 64 is able to guide the corresponding signaling member 61 in translation in the signaling direction between the inactive position and the active signaling position or positions.

L'index de signalisation 66 est venu de matière avec la languette 62. L'index de signalisation 66 est visible à travers la fenêtre de visualisation 54 lorsque l'organe de signalisation 61 correspondant est en position active. L'index de signalisation 66 n'est pas visible à travers la fenêtre de visualisation 54, et est masqué par le couvercle 36 depuis l'extérieur du dispositif de commutation 2, lorsque l'organe de signalisation 61 correspondant est en position inactive.The signaling index 66 is integral with the tongue 62. The signaling index 66 is visible through the viewing window 54 when the corresponding signaling member 61 is in the active position. The signaling index 66 is not visible through the viewing window 54, and is masked by the cover 36 from outside the switching device 2, when the corresponding signaling member 61 is in the inactive position.

L'index de signalisation 66 est de préférence de couleur vive pour permettre sa visualisation facilement à travers la fenêtre 54. Si plusieurs index de signalisation 66 sont présents sur une même languette 62, chaque index de signalisation 66 est de préférence d'une couleur distincte des autres index de signalisation 66 présents sur la même languette 62.The signaling index 66 is preferably brightly colored so that it can easily be viewed through the window 54. If a plurality of signaling indicia 66 are present on the same tab 62, each signaling index 66 is preferably of a distinct color. other signaling indexes 66 present on the same tongue 62.

Chaque cavité de retenue 70 est apte à collaborer par encliquetage avec la ou les saillies de maintien 68 portées par la languette 62 correspondante pour maintenir l'organe de signalisation 61 correspondant en position inactive en l'absence de bloc auxiliaire 6 dans le logement de réception 14 associé audit organe de signalisation 61. Chaque cavité de retenue 70 permet donc de s'assurer que l'organe de signalisation 61 correspondant n'est pas déplacé involontairement vers une position active de signalisation.Each retaining cavity 70 is able to collaborate by latching with the one or more holding projections 68 carried by the corresponding tongue 62 to keep the corresponding signaling member 61 in the inactive position in the absence of an auxiliary block 6 in the receiving housing. 14 associated with said signaling member 61. Each holding cavity 70 thus ensures that the corresponding signaling member 61 is not inadvertently moved to an active signaling position.

La butée d'arrêt 74 est apte à collaborer avec une face interne 78 correspondante de la cavité 76 pour empêcher le mouvement de l'organe de signalisation 61 correspondant au-delà d'une dernière position active de signalisation. Pour cela, la butée d'arrêt 74 comporte une paroi d'arrêt 80 sensiblement perpendiculaire à la direction de signalisation.The stopper 74 is able to collaborate with a corresponding inner face 78 of the cavity 76 to prevent the movement of the corresponding signaling member 61 beyond a last active signaling position. For this, the stopper 74 comprises a stop wall 80 substantially perpendicular to the signaling direction.

Ainsi, le dispositif de commutation 2 est apte à indiquer la présence d'un bloc auxiliaire 6 dans un logement de réception 14 correspondant sans effort spécifique pour l'opérateur. Dans l'exemple des figures 1 à 5, si les moyens de signalisation 48 sont en position inactive de signalisation lors de la fermeture du couvercle 36, chaque came 72 vient en appui contre chaque bloc auxiliaire 6 comme visible sur la figure 6. Chaque came 72 entraîne alors la translation de l'organe de signalisation 61 correspondant depuis sa position inactive vers sa position active de signalisation, dans laquelle l'index de signalisation 66 correspondant est visible à travers la fenêtre de visualisation 54 correspondante.Thus, the switching device 2 is able to indicate the presence of an auxiliary block 6 in a corresponding receiving housing 14 without specific effort for the operator. In the example of Figures 1 to 5 if the signaling means 48 are in the idle signaling position when the lid 36 is closed, each cam 72 abuts against each auxiliary block 6 as visible on the figure 6 . Each cam 72 then causes translation of the corresponding signaling member 61 from its inactive position to its active signaling position, in which the corresponding signaling index 66 is visible through the corresponding display window 54.

Un opérateur extérieur peut alors aisément identifier à la vue de la ou des fenêtres de visualisation 54 si chaque logement de réception 14 correspondant contient ou non un bloc auxiliaire 6.An external operator can then easily identify at the sight of the viewing window or windows 54 whether or not each corresponding receiving slot 14 contains an auxiliary block 6.

Cette signalisation est en outre particulièrement fiable, car il n'est pas possible, de par la présence de chaque came 72, de déplacer les moyens de signalisation 48 dans la position inactive de signalisation en présence d'un bloc auxiliaire 6 dans un logement de réception 14 donné.This signaling is also particularly reliable, because it is not possible, by the presence of each cam 72, to move the signaling means 48 in the idle signaling position in the presence of an auxiliary block 6 in a housing of reception 14 given.

Le dispositif de commutation 2 est fourni, en sortie d'usine, de préférence avec les moyens de signalisation 48 en position inactive.The switching device 2 is supplied at the factory outlet, preferably with the signaling means 48 in the inactive position.

Les moyens de maintien 50 sont en outre aptes à retenir les moyens de signalisation 48 en position inactive en l'absence de bloc auxiliaire 6. Les moyens de maintien permettent donc d'éviter que les moyens de signalisation 48 soient déplacés par inadvertance vers la position active de signalisation en l'absence de bloc auxiliaire 6.The holding means 50 are furthermore capable of holding the signaling means 48 in the inactive position in the absence of an auxiliary block 6. The holding means therefore make it possible to prevent the signaling means 48 from being inadvertently moved to the position active signaling in the absence of auxiliary block 6.

En complément facultatif, le couvercle 36 est muni d'organes élastiques de rappel qui sont configurés pour rappeler les moyens de signalisation 48 dans leur position inactive de signalisation en l'absence de bloc auxiliaire 6 et/ou en l'absence d'action de la part des moyens de commande 52. Les organes de rappel engendrent alors un retour des moyens de signalisation 48 dans leur position inactive notamment lors de l'ouverture de l'enveloppe externe 12, cette ouverture entraînant le déplacement du couvercle 36 à l'écart du socle, des logements de réception 14 et des éventuels blocs auxiliaires 6.In addition optional, the cover 36 is provided with elastic return members which are configured to recall the signaling means 48 in their position inactive signaling in the absence of auxiliary block 6 and / or in the absence of action on the part of the control means 52. The return members then generate a return of the signaling means 48 in their inactive position, particularly when the opening of the outer casing 12, this opening causing the displacement of the cover 36 away from the base, receiving housings 14 and any auxiliary blocks 6.

Selon ce complément facultatif, les organes de rappel permettent alors d'éviter une erreur de signalisation notamment dans le cas où un bloc auxiliaire 6 a été mis en place dans un logement de réception 14 correspondant, puis en a été retiré par un opérateur sans qu'il pense à replacer l'organe de signalisation 61 associé dans sa position inactive.According to this optional complement, the return members then make it possible to avoid a signaling error, in particular in the case where an auxiliary block 6 has been put in place in a corresponding receiving housing 14, and then has been removed by an operator without having he thinks to replace the associated signaling member 61 in its inactive position.

Ces organes de rappel facilitent de manière générale encore davantage l'intervention de l'opérateur, puisqu'il n'a alors pas besoin d'agir sur le ou les organes de signalisation 61, chaque organe de signalisation 61 étant automatiquement déplacé vers sa position active en présence d'un bloc auxiliaire 6 dans le logement de réception 14 associé de par les moyens de commande 52, et également automatiquement déplacé vers sa position inactive de par les organes de rappel, dès que les moyens de commande 52 ne sont plus actionnés, c'est-à-dire notamment suite au retrait dudit bloc auxiliaire 6 du logement de réception 14 associé ou suite à l'ouverture de l'enveloppe externe 12.These return members generally make it easier for the operator to intervene, since he then does not need to act on the signaling member (s) 61, each signaling member 61 being automatically moved to its position. active in the presence of an auxiliary block 6 in the receiving housing 14 associated with the control means 52, and also automatically moved to its inactive position by the return members, as soon as the control means 52 are no longer actuated , that is to say in particular following the withdrawal of said auxiliary block 6 from the associated receiving housing 14 or following the opening of the outer casing 12.

Dans le cas où les moyens de signalisation 48 comprennent une languette 62 mobile en translation, la fenêtre de visualisation 54 n'est pas nécessairement située en regard du bloc auxiliaire 6 correspondant. Cela permet la visualisation des moyens de signalisation 48 par un opérateur même dans le cas où l'espace situé en regard des logements 14 est occulté par d'autres dispositifs. Autrement dit, chaque languette 62 permet de déporter, dans une zone du couvercle 36 qui est à l'écart du logement de réception 14 correspondant, la visualisation de la présence ou de l'absence d'un bloc auxiliaire 6 dans ledit logement de réception 14.In the case where the signaling means 48 comprise a tongue 62 movable in translation, the viewing window 54 is not necessarily located opposite the corresponding auxiliary block 6. This allows the visualization of the signaling means 48 by an operator even in the case where the space facing the housings 14 is obscured by other devices. In other words, each tongue 62 makes it possible to move, in an area of the cover 36 which is away from the corresponding receiving housing 14, the visualization of the presence or absence of an auxiliary block 6 in said receiving housing. 14.

Il est alors possible selon les applications prévues pour chaque type de dispositif de commutation 2 d'adapter les moyens de visualisation 48 pour déporter la fenêtre de visualisation 54 vers la zone la plus adaptée du couvercle 36.It is then possible according to the applications provided for each type of switching device 2 to adapt the display means 48 to move the viewing window 54 towards the most adapted zone of the cover 36.

On conçoit ainsi que le dispositif de commutation 2 selon l'invention permet une signalisation efficace et pérenne de la présence d'un ou plusieurs blocs auxiliaires 6, tout en limitant les tâches à la charge de l'opérateur qui personnalise le dispositif de commutation électrique 2 et en minimisant le risque d'erreurs humaines.It is thus conceivable that the switching device 2 according to the invention allows an effective and lasting signaling of the presence of one or more auxiliary blocks 6, while limiting the tasks to the load of the operator who customizes the electrical switching device. 2 and minimizing the risk of human errors.
