Description

L'invention est relative à un disjoncteur à boîtier moulé comprenant une face avant, un orifice ménagé dans la face avant, une poignée pivotante de commande manuelle traversant ledit orifice et faisant saillie de ladite face avant, une bordure en forme de cadre en saillie de la face avant et encadrant ledit orifice, un bloc déclencheur interchangeable de commande d'ouverture automatique du disjoncteur lors d'un défaut et un moyen indicateur, notamment du calibre du bloc déclencheur.The invention relates to a molded case circuit breaker comprising a front face, an orifice formed in the front face, a pivoting handle for manual control passing through said orifice and projecting from said front face, a frame-shaped border projecting from the front face and framing said orifice, an interchangeable trip unit for automatic opening control of the circuit breaker in the event of a fault and an indicator means, in particular of the size of the trip unit.

Un disjoncteur connu du genre mentionné (voir p. ex. GB-A-2 091 505) peut être équipé de différents blocs déclencheurs, notamment de déclencheurs de calibres différents, lesdits blocs pouvant être des déclencheurs électroniques ou électromagnétiques. Le calibre ou les caractéristiques du bloc déclencheur sont inscrits sur la partie frontale permettant à l'installateur ou à l'utilisateur une vérification des caractéristiques du'disjoncteur. Les disjoncteurs et autres appareils électriques sont généralement installés et groupés dans des armoires électriques, elles-mêmes équipées de plastron, laissant accessibles uniquement les organes de manoeuvres, en l'occurrence la poignée de commande du disjoncteur. Le plastron recouvre le bloc déclencheur et les inscriptions correspondantes, seul le démontage du plastron permettant une lecture et une vérification des caractéristiques du disjoncteur. Il est possible de pratiquer un orifice dans le plastron en regard de l'instruction, mais cette opération est compliquée, et le positionnement correct de l'orifice n'est pas garanti.A known circuit breaker of the kind mentioned (see for example GB-A-2 091 505) can be equipped with different trip units, in particular trip units of different ratings, said units being electronic or electromagnetic trips. The rating or characteristics of the trip unit are written on the front allowing the installer or user to check the characteristics of the circuit breaker. Circuit breakers and other electrical devices are generally installed and grouped in electrical cabinets, themselves equipped with faceplates, leaving accessible only the operating devices, in this case the circuit breaker control handle. The faceplate covers the trip unit and the corresponding inscriptions, only the disassembly of the faceplate allowing a reading and a verification of the characteristics of the circuit breaker. It is possible to practice an opening in the faceplate opposite the instruction, but this operation is complicated, and the correct positioning of the opening is not guaranteed.

La présente invention a pour but de permettre de réaliser un disjoncteur à bloc déclencheur interchangeable du genre mentionné, dont les caractéristiques du bloc déclencheur associé au disjoncteur, sont en toutes circonstances visibles.The object of the present invention is to make it possible to produce a circuit breaker with an interchangeable trip block of the kind mentioned, the characteristics of the trip block associated with the circuit breaker, being visible in all circumstances.

Le disjoncteur selon l'invention est caractérisé en ce que ladite bordure comporte une fenêtre, que le bloc déclencheur comporte un support dudit moyen indicateur , agencé pour coopérer avec ladite fenêtre lorsque le bloc déclencheur est en place, pour rendre visible le moyen indicateur sur la bordure et ladite face avant .The circuit breaker according to the invention is characterized in that said border includes a window, that the trip unit comprises a support of said indicator means, arranged to cooperate with said window when the trip unit is in place, to make the indicator means visible on the border and said front face.

La bordure en forme de cadre a notamment pour rôle le centrage du plastron par rapport au disjoncteur. L'ouverture ménagée dans le plastron pour le passage de la poignée, doit permettre le libre débattement de cette poignée, et à cet effet cette ouverture est d'une dimension correspondant à la bordure en cadre, de façon à s'encastrer sur cette dernière et à centrer l'ouverture par rapport à la poignée. On évite ainsi tout décalage relatif susceptible d'entraver l'actionnement de la poignée. En reportant l'indication du calibre sur la bordure en cadre, cette indication reste visible après la mise en place du plastron et permet ainsi toute vérification ultérieure. La bordure en cadre porte avantageusement d'autres indications, notamment de la position d'ouverture et de fermeture de la poignée, ou d'autres commandes ou réglages du disjoncteur.The role of the frame-shaped border is in particular to center the faceplate relative to the circuit breaker. The opening in the faceplate for the passage of the handle must allow the free movement of this handle, and for this purpose this opening is of a dimension corresponding to the frame border, so as to be embedded on the latter and center the opening relative to the handle. We This avoids any relative offset that could hinder the actuation of the handle. By transferring the indication of the size to the frame border, this indication remains visible after the fitting of the faceplate and thus allows any subsequent verification. The frame border advantageously bears other indications, in particular the opening and closing position of the handle, or other commands or settings of the circuit breaker.

L'inscription du calibre du bloc déclencheur est de préférence portée sur l'extrémité d'une console, solidaire du bloc déclencheur, laquelle console est agencée pour venir en regard de la fenêtre ménagée dans la bordure en forme de cadre, pour rendre visible l'inscription à travers ladite fenêtre. L'extrémité de la console s'insère avantageusement sans jeu dans la fenêtre et affleure celle-ci pour assurer une continuité de la bordure en forme de cadre. L'enveloppe du bloc déclencheur et la console sont en une seule pièce et toute erreur de montage est ainsi exclue. Il est néanmoins concevable de réaliser ces éléments en deux parties, en prévoyant des systèmes détrompeurs évitant toute erreur de montage.The inscription of the caliber of the trigger block is preferably worn on the end of a console, integral with the trigger block, which console is arranged to come opposite the window formed in the frame-shaped border, to make visible the 'inscription through said window. The end of the console is advantageously inserted without play in the window and is flush with the latter to ensure continuity of the frame-shaped border. The casing of the trip unit and the console are in one piece and any assembly error is thus excluded. It is nevertheless conceivable to produce these elements in two parts, by providing polarizing systems avoiding any assembly error.

D'autres avantages et caractéristiques ressortiront plus clairement de la description qui va suivre, d'un mode de mise en oeuvre de l'invention, donné à titre d'exemple non limitatif, et représenté aux dessins annexés, dans lesquels:Other advantages and characteristics will emerge more clearly from the description which follows, of an embodiment of the invention, given by way of nonlimiting example, and represented in the appended drawings, in which:

La figure 1 est une vue schématique en perspective d'un disjoncteur selon l'invention.Figure 1 is a schematic perspective view of a circuit breaker according to the invention.

La figure 2 est une vue en perspective du bloc déclencheur du disjoncteur selon la figure 1.FIG. 2 is a perspective view of the trip unit of the circuit breaker according to FIG. 1.

La figure 3 est une vue en élévation et en coupe du disjoncteur selon la figure 1.FIG. 3 is a view in elevation and in section of the circuit breaker according to FIG. 1.

Sur les figures, un disjoncteur comprend un boîtier moulé 10, en plusieurs parties, notamment avec un couvercle 11 présentant un orifice 12 de passage d'une poignée 13 de commande manuelle du disjoncteur. Un bloc déclencheur 14, notamment électronique, est incorporé ou accolé au boîtier moulé 10 pour commander l'ouverture automatique du disjoncteur en cas de défaut. Le bloc déclencheur 14 est interchangeable et à chaque appareil est associée une gamme de déclencheurs correspondant à des calibres différents. Le disjoncteur est personnalisé lors de l'installation, en lui associant un bloc déclencheur 14 de calibre approprié à la protection recherchée. L'orifice 12 de débattement de la poignée 13, de forme rectangulaire est encadré par une bordure 15, en forme de cadre rectangulaire, faisant saillie de la face avant 16 du couvercle 11. Cette bordure 15 en saillie participe au renforcement du couvercle 11 dans cette zone, et elle assure le centrage d'un plastron (non représenté) de protection, appliqué sur les faces avant des appareils, et présentant des fenêtres s'emboîtant sur les bordures en saillie. Seule la poignée 13, et la bordure 15 en forme de cadre reste accessibles, toutes les autres parties, notamment les parties sous tension étant coiffées par le plastron. La bordure en forme de cadre évite tout décalage relatif du plastron par rapport à la poignée 13, et assure ainsi le libre pivotement de cette dernière. Un tel disjoncteur qui comprend des contacts de coupure 17, et un mécanisme 18 de commande de ces contacts 17, est bien connu et par exemple décrit dans la demande de brevet français n°92.1486 déposée le 7.02.1992 par la demanderesse, le lecteur se reportant avantageusement à cette demande pour de plus amples détails.In the figures, a circuit breaker comprises a molded housing 10, in several parts, in particular with a cover 11 having an orifice 12 for the passage of a handle 13 for manual control of the circuit breaker. A trip unit 14, in particular electronic, is incorporated or attached to the molded housing 10 to control the automatic opening of the circuit breaker in the event of a fault. The trigger block 14 is interchangeable and each device is associated with a range of triggers corresponding to different calibers. The circuit breaker is personalized during installation, by associating it with a trip unit 14 of a caliber appropriate to the protection sought. The orifice 12 of movement of the handle 13, of form rectangular is surrounded by a border 15, in the form of a rectangular frame, projecting from the front face 16 of the cover 11. This projecting border 15 contributes to the reinforcement of the cover 11 in this area, and it ensures the centering of a plastron ( not shown) of protection, applied to the front faces of the devices, and having windows fitting onto the projecting edges. Only the handle 13, and the border 15 in the form of a frame remains accessible, all the other parts, in particular the parts under tension, being capped by the faceplate. The frame-shaped border avoids any relative offset of the faceplate relative to the handle 13, and thus ensures the free pivoting of the latter. Such a circuit breaker which comprises breaking contacts 17, and a mechanism 18 for controlling these contacts 17, is well known and for example described in French patent application No. 92.1486 filed on 7.02.1992 by the applicant, the reader Advantageously deferring to this request for further details.

L'enveloppe 19 du bloc déclencheur 14, en matière plastique moulée présente une console 20 venant de moulage avec cette enveloppe. L'extrémité libre 21 de la console 20 présente une face 22 qui porte une inscription 23, par exemple du calibre du bloc déclencheur. La bordure 15, en forme de cadre porte une fenêtre 24 de forme conjuguée, de celle de la face avant 22 de la console 20, notamment de forme rectangulaire, et l'ensemble est agencé de telle manière, qu'en position montée du bloc déclencheur 14, la face avant 22 avec l'inscription 23 s'inscrit dans la fenêtre 24. Cette face avant occupe avantageusement toute la fenêtre 24 et affleure la bordure 15. Dans l'exemple illustré par les figures, le couvercle 11 est mis en place en dernier, et la fenêtre 24 vient s'emboîter sur l'extrémité 21 de la console 20, mais il convient de noter que d'autres agencements sont concevables, notamment un système de fixation du bloc déclencheur permettant une insertion de l'extrémité libre 21 de la console 20 dans la fenêtre 24 lors du montage du bloc déclencheur. La face avant 22 peut également rester en retrait et être simplement en face de la fenêtre 24 pour permettre une lecture de l'inscription 23, à partir de la face avant du disjoncteur. n est également possible d'utiliser une console associée au bloc déclencheur 14, mais indépendante de ce dernier, cette console comprenant des détrompeurs empêchant la mise en place dans la fenêtre 24 d'une console 20 ne correspondant pas au bloc déclencheur 14 monté sur le disjoncteur. Le dispositif est particulièrement simple et toute erreur de montage est exclue. La bordure 15 en saillie porte, de plus, un bouton 25 de commande de déclenchement du disjoncteur et d'autres inscriptions 26, notamment d'ouverture et de fermeture du disjoncteur.The casing 19 of the trigger block 14, made of molded plastic material has a console 20 coming from molding with this casing. The free end 21 of the console 20 has a face 22 which bears an inscription 23, for example of the caliber of the trigger block. The edge 15, in the form of a frame carries a window 24 of conjugate shape, that of the front face 22 of the console 20, in particular of rectangular shape, and the assembly is arranged in such a way that, in the assembled position of the block trigger 14, the front face 22 with the inscription 23 is inscribed in the window 24. This front face advantageously occupies the entire window 24 and is flush with the border 15. In the example illustrated by the figures, the cover 11 is placed in place last, and the window 24 comes to fit on the end 21 of the console 20, but it should be noted that other arrangements are conceivable, in particular a system for fixing the trigger block allowing insertion of the end free 21 of the console 20 in the window 24 during the mounting of the trip unit. The front face 22 can also remain set back and simply be in front of the window 24 to allow reading of the inscription 23, from the front face of the circuit breaker. n is also possible to use a console associated with the trigger block 14, but independent of the latter, this console comprising polarizing blocks preventing the installation in the window 24 of a console 20 not corresponding to the trigger block 14 mounted on the circuit breaker. The device is particularly simple and any assembly error is excluded. The protruding border 15 also carries a button 25 for controlling the tripping of the circuit breaker and other inscriptions 26, in particular for opening and closing the circuit breaker.

L'invention est applicable à tout disjoncteur à boîtier moulé à blocs déclencheurs interchangeables, et elle n'est pas limitée à une forme d'inscription ou à un type d'inscription.The invention is applicable to any circuit breaker with molded housing with interchangeable trip units, and it is not limited to a form of registration or a type of registration.
