Description

La présente invention concerne un boítier destiné au logement d'un appareil électrique tel un disjoncteur et comportant, à l'une au moins de ses extrémités, des compartiments de borne dans lesquels sont logés respectivement des plages de raccordement et des moyens de fixation desdites plages à des conducteurs extérieurs tels une barre, un câble etc.The present invention relates to a housing for housing an electrical device such a circuit breaker and comprising, at at least one of its ends, compartments for terminal in which are respectively housed connection pads and means of fixing of said pads to external conductors such as a bar, a cable etc.

Il existe actuellement différentes possibilités de raccordement de puissance d'un disjoncteur basse tension par l'avant de l'appareil. On connaít en effet le raccordement à des câbles par l'intermédiaire de bornes, le raccordement à des barres ou le raccordement du type "déconnectable" à un conducteur rigide fixe.
Généralement, le passage d'un mode de raccordement à l'autre nécessite l'utilisation de pièces différentes. Par exemple, pour la fixation d'une plage de raccordement à une barre, il est nécessaire d'immobiliser les vis en rotation. L'une des solutions utilisées consiste à monter les vis dans des "clips" métalliques ou plaquettes isolantes fixés de manière amovible aux plages de raccordement. Après montage des barres sur les vis, celles-ci sont retenues sur les plages de raccordement par des écrous. Par contre, pour le raccordement à des câbles de puissance, une telle immobilisation des vis n'est pas nécessaire. Ces dernières sont montées à travers les plages par l'arrière de l'appareil et vissées directement dans les bornes montées à cet effet sur les plages de raccordement. Selon ces réalisations, les distances d'isolement sont assurées soit par un couvercle vissé sous l'appareil (dans le cas de l'utilisation d'un clips), soit par une forme et des dimensions appropriées de la plaquette précitée, lorsque celle-ci est utilisée.There are currently various possibilities for power connection of a low voltage circuit breaker from the front of the device. We know indeed the connection to cables via terminals, the connection to bars or the connection of the "disconnectable" type to a fixed rigid conductor.
Generally, switching from one connection method to another requires the use of different parts. For example, for fixing a connection pad to a bar, it is necessary to immobilize the rotating screws. One of the solutions used consists in mounting the screws in metal "clips" or insulating plates removably attached to the connection pads. After mounting the bars on the screws, they are retained on the connection areas by nuts. On the other hand, for connection to power cables, such immobilization of the screws is not necessary. The latter are mounted across the shelves from the rear of the device and screwed directly into the terminals mounted for this purpose on the connection pads. According to these embodiments, the isolation distances are ensured either by a cover screwed under the device (in the case of the use of a clip), or by an appropriate shape and dimensions of the aforementioned plate, when it this is used.

La présente invention propose un boítier d'appareillage électrique de conception simple, permettant de réaliser différents types de connexion en utilisant un minimum de pièces.The present invention provides an electrical appliance box of simple design, allowing to make different types of connection using a minimum of parts.

A cet effet, la présente invention a pour objet un boítier du genre précédemment mentionné, caractérisé en ce que les moyens de fixation des plages aux conducteurs comprennent, pour l'un au moins des compartiments précités au moins une première ouverture prévue dans le boítier, au moins une seconde ouverture prévue dans la plage de raccordement et située(s) en regard de la (des) première(s) ouverture(s), et au moins une vis traversant deux ouvertures en regard du boítier et de la plage pour assurer la fixation d'un conducteur sur la plage de raccordement, ladite première ouverture étant conformée de manière d'une part, à recevoir et à guider en rotation au moins une tête de vis de forme circulaire et d'autre part, à bloquer en rotation par rapport au boítier au moins une tête de vis de forme appropriée non circulaire. To this end, the present invention relates to a housing of the kind previously mentioned, characterized in that the means for fixing the pads to the conductors comprise, for at least one of the above-mentioned compartments at least one first opening provided in the housing, at least one second opening provided in the connection area and located (s) opposite the first opening (s), and at least one screw passing through two openings facing the housing and the range to ensure the fixing of a conductor on the connection pad, said first opening being shaped on the one hand, to receive and guide in rotation at least one screw head of circular shape and on the other hand, to block in rotation relative to the housing at least one screw head of suitable shape not circular.

Selon une caractéristique particulière de l'invention, les vis à tête circulaire sont destinées à la fixation de bornes sur la plage de raccordement.According to a particular characteristic of the invention, the circular head screws are intended to the fixing of terminals on the connection area.

Selon une caractéristique particulière de l'invention, les vis à tête non circulaire précitées sont destinées à la fixation de barres sur les plages de raccordement.According to a particular characteristic of the invention, the aforementioned non-circular head screws are intended for fixing bars on the connection pads.

Selon une autre caractéristique, la ou chaque première ouverture est également adaptée à recevoir un conducteur rigide fixe.According to another characteristic, the or each first opening is also adapted to receive a fixed rigid conductor.

Selon une autre caractéristique, la ou chaque première ouverture forme au moins un logement de forme sensiblement hexagonale coopérant avec au moins une vis dont la tête est sensiblement de même forme.According to another characteristic, the or each first opening forms at least one housing substantially hexagonal cooperating with at least one screw whose head is substantially the same shape.

Mais d'autres avantages et caractéristiques de l'invention apparaítront mieux dans la description détaillée qui suit et se réfère aux dessins annexés donnés uniquement à titre d'exemple et dans lesquels :

  • La figure 1 est une vue partielle en perspective, illustrant la partie arrière d'un disjoncteur basse tension logé dans un boítier conforme à l'invention et dans lequel le mode de raccordement du type "borne" est utilisé,
  • les figures 2 et 3 sont des vues partielles en coupe longitudinale de la figure précédente, respectivement en position non raccordée et raccordée du câble,
  • la figure 4 est une vue en coupe similaire aux figures 2 et 3, illustrant le mode de raccordement du type barre,
  • la figure 5 est une vue partielle en perspective, illustrant la partie avant du boítier d'un disjoncteur, le mode de raccordement du type déconnectable étant utilisé,
  • la figure 6 est une vue partielle en coupe longitudinale de la figure 5, et
  • la figure 7 est une vue partielle en perspective, illustrant la partie arrière d'un disjoncteur basse tension logé dans un boítier conforme à une autre réalisation de l'invention.
However, other advantages and characteristics of the invention will appear better in the detailed description which follows and refers to the appended drawings given solely by way of example and in which:
  • FIG. 1 is a partial perspective view, illustrating the rear part of a low voltage circuit breaker housed in a box according to the invention and in which the "terminal" type of connection mode is used,
  • FIGS. 2 and 3 are partial views in longitudinal section of the previous figure, respectively in the unconnected and connected position of the cable,
  • FIG. 4 is a sectional view similar to FIGS. 2 and 3, illustrating the connection type of the bar type,
  • FIG. 5 is a partial perspective view, illustrating the front part of the case of a circuit breaker, the connection mode of the disconnectable type being used,
  • FIG. 6 is a partial view in longitudinal section of FIG. 5, and
  • Figure 7 is a partial perspective view illustrating the rear part of a low voltage circuit breaker housed in a housing according to another embodiment of the invention.

Sur la figure 1, on voit un disjoncteur basse tension de puissance D logé dans un boítier moulé isolant 1, ledit boítier 1 comportant à l'une de ses extrémités la (la seule visible sur cette figure), des compartiments 2 dans lesquels s'étendent les plages de raccordement 3 de l'appareil.In Figure 1, we see a low voltage power circuit breaker D housed in a housing molded insulator 1, said housing 1 comprising at one of its ends the (the only visible on this figure), compartments 2 in which extend the connection pads 3 of the device.

Selon la réalisation illustrée sur les figures 1 à 3, ces compartiments 2 sont destinés à loger des bornes 4 pour le raccordement des plages précitées 3 à des câbles de puissance 5. Ces bornes 4 sont constituées par des blocs 6 fixés sur les plages 3 par l'intermédiaire de vis 7 introduites par l'arrière du boítier 1, à travers deux ouvertures 8, 16 respectivement première et seconde prévues respectivement dans le boítier 1 et dans la plage correspondante 3, avant de se visser dans l'une des extrémités de la borne correspondante 4.According to the embodiment illustrated in Figures 1 to 3, these compartments 2 are intended to accommodate terminals 4 for connecting the aforementioned areas 3 to power cables 5. These terminals 4 are constituted by blocks 6 fixed on the pads 3 by means of screws 7 introduced from the rear of the housing 1, through two openings 8, 16 respectively first and second provided respectively in the housing 1 and in the range 3, before screwing into one of the ends of the corresponding terminal 4.

Comme on le voit plus particulièrement sur la figure 1, à chaque compartiment 2 du boítier 1 est associée une ouverture 8, dite première, ménagée dans la partie arrière du boítier 1 et permettant le passage de deux vis de fixation d'une borne 4. Cette ouverture 8 forme deux logements 8a, 8b, de forme sensiblement hexagonale, reliées par une partie rectiligne 8c.As seen more particularly in Figure 1, each compartment 2 of the housing 1 is associated with an opening 8, said first, formed in the rear part of the housing 1 and allowing the passage of two terminal fixing screws 4. This opening 8 forms two housings 8a, 8b, of substantially hexagonal shape, connected by a rectilinear part 8c.

Ces deux logements 8a, 8b sont conformés de manière à recevoir et à permettre, chacun, la libre rotation d'une vis à tête ronde 9, 10 et à empreinte creuse utilisée pour la fixation d'une borne 4.These two housings 8a, 8b are shaped so as to each receive and allow the free rotation of a round head screw 9, 10 and with a hollow recess used for fixing a terminal 4.

Sur la figure 4, on voit que les plages de raccordement 3 sont connectées chacune à une barre 23. Dans ce cas, les vis de fixation de barre 23 nécessitent d'être immobilisées en rotation. A cet effet, on utilise des vis présentant une tête hexagonale 11, 12, lesquelles, lorsqu'introduites dans les ouvertures 8, sont immobilisées en rotation par les parois délimitant les portions d'ouvertures 8a, 8b de forme hexagonale.In FIG. 4, it can be seen that the connection pads 3 are each connected to a bar 23. In this case, the bar fixing screws 23 need to be immobilized in rotation. For this purpose, screws having a hexagonal head 11, 12 are used, which, when introduced into the openings 8, are immobilized in rotation by the walls delimiting the portions of openings 8a, 8b of hexagonal shape.

Sur les figures 5 et 6, le raccordement des plages 3 s'effectue selon le mode déconnectable. Ainsi, les ouvertures 8 prévues dans le boítier 1 sont destinées à recevoir chacune l'extrémité libre 13a d'une broche de connexion fixe 13, dont la forme correspond à celle de l'ouverture 8.In FIGS. 5 and 6, the pads 3 are connected in the disconnectable mode. Thus, the openings 8 provided in the housing 1 are intended to receive each the free end 13a of a fixed connection pin 13, the shape of which corresponds to that of the opening 8.

Chacune des ouvertures 8 prévues dans le boítier 1 est obturée par un couvercle 19 isolant relié de manière articulée audit boítier 1 par une charnière 14 intégrée audit couvercle 19. Cette charnière est fixée au boítier par un clip (C), permettant au couvercle de rester solidaire du boítier en position d'ouverture dudit couvercle. On notera également qu'au moment de la fermeture, le couvercle est fermé au moyen d'un autre clip. Each of the openings 8 provided in the housing 1 is closed by an insulating cover 19 hingedly connected to said housing 1 by a hinge 14 integrated into said cover 19. This hinge is fixed to the housing by a clip (C), allowing the cover to remain secured to the housing in the open position of said cover. Note also that at when closing, the cover is closed with another clip.

On décrira ci-après brièvement l'opération de raccordement en fonction du type de raccordement choisi.The connection operation will be described briefly below according to the type of connection chosen.

Lorsque le raccordement s'effectue au moyen de bornes 4, les couvercles 19 sont amenés en position d'ouverture (fig.2), puis deux vis à tête ronde 9, 10 sont introduites dans l'ouverture correspondante 8. Les vis sont alors vissées dans la borne 4 au moyen d'un outil approprié, les têtes de vis tournant librement dans les ouvertures 8. On introduit alors les câbles de puissance 5 dans les orifices 22 prévus à cet effet dans les bornes 4 (fig. 3).When the connection is made by means of terminals 4, the covers 19 are brought into open position (fig. 2), then two round head screws 9, 10 are introduced into the corresponding opening 8. The screws are then screwed into terminal 4 using a tool suitable, the screw heads rotating freely in the openings 8. The power cables 5 in the holes 22 provided for this purpose in the terminals 4 (fig. 3).

Lorsque le raccordement s'effectue sur une barre 23, deux vis à tête hexagonale 11, 12 sont préalablement introduites par l'arrière de l'appareil D dans les ouvertures correspondantes 8, 16 du boítier 1 et de la plage 3 après ouverture des couvercles 19. Les têtes de vis 11, 12 étant immobilisées dans le boítier 1, la fixation de la barre 23 sur la plage 3 est assurée par l'intermédiaire d'un écrou 15.When the connection is made on a bar 23, two hexagonal screws 11, 12 are previously introduced from the rear of the device D into the corresponding openings 8, 16 of the housing 1 and of the area 3 after opening the covers 19. The screw heads 11, 12 being immobilized in the housing 1, the fixing of the bar 23 on the track 3 is ensured by through a nut 15.

Si le mode de raccordement du type déconnectable est choisi, l'appareil D est déplacé en direction de conducteurs fixes sous forme de broches 13 de manière à introduire l'extrémité 13a desdites broches 13 à l'intérieur des ouvertures 8 du boítier 1. La fixation des broches 13 sur les plages 3 s'effectue au moyen d'une vis 17 introduite par l'avant des appareils D à travers les deux orifices 16, 8 prévus respectivement dans la plage 3 et le boítier 1 et vissée dans l'extrémité correspondante 13a des broches 13. Chaque conducteur rigide ou broche 13 comporte une extrémité 13a comprenant deux colonnes 18, 19 de section sensiblement hexagonale reliées par une traverse 20 et comportant chacune un orifice 21 de fixation destiné à recevoir ladite vis 17, ladite extrémité 13a coopérant avec une première ouverture 8 de forme correspondante du boítier 1.If the connection type of the disconnectable type is chosen, the device D is moved in direction of fixed conductors in the form of pins 13 so as to introduce the end 13a of said pins 13 inside the openings 8 of the housing 1. The fixing of the pins 13 on tracks 3 is effected by means of a screw 17 inserted from the front of the devices D through the two orifices 16, 8 provided respectively in the range 3 and the housing 1 and screwed into the corresponding end 13a of the pins 13. Each rigid conductor or pin 13 has one end 13a comprising two columns 18, 19 of section substantially hexagonal connected by a cross member 20 and each comprising an orifice 21 of fixing intended to receive said screw 17, said end 13a cooperating with a first opening 8 of corresponding shape of the housing 1.

On notera que dans le cas où ce mode de raccordement est choisi, il n'est pas absolument nécessaire que la broche soit immobilisée en rotation dans l'ouverture et donc que la forme de la broche corresponde exactement à celle de l'ouverture.Note that if this connection method is chosen, it is not absolutely necessary that the spindle is immobilized in rotation in the opening and therefore that the shape of the spindle corresponds exactly to that of the opening.

Selon une autre réalisation particulière de l'invention, ce boítier comporte en outre une pièce de renfort 24 introduite dans chaque première ouverture, laquelle présente une section légèrement agrandie par rapport aux ouvertures du mode de réalisation précédent, afin d'améliorer la résistance du boítier au maintien des vis.According to another particular embodiment of the invention, this housing further comprises a reinforcement piece 24 inserted into each first opening, which has a cross section slightly enlarged compared to the openings of the previous embodiment, so to improve the resistance of the housing to the maintenance of the screws.

Avantageusement, cette pièce de renfort 24 est amovible de manière à permettre, lorsque celle-ci est extraite du boítier, le logement d'un conducteur rigide fixe de section légèrement agrandie. Advantageously, this reinforcing piece 24 is removable so as to allow, when this is extracted from the housing, the housing of a fixed rigid conductor of section slightly enlarged.

On notera que la forme hexagonale des logements et des têtes de vis n'est donnée qu'à titre d'exemple. D'autres formes pour les logements et les têtes de vis pourront bien entendu être envisagées dans le cadre de l'invention pourvu qu'elles permettent le blocage de ces vis en rotation et qu'elles permettent la libre rotation de vis à tête circulaire. Les vis utilisées seront avantageusement des vis normalisées.Note that the hexagonal shape of the housings and the screw heads is only given as example. Other shapes for the housings and the screw heads could of course be envisaged in the context of the invention provided that they allow the blocking of these screws in rotation and that they allow the free rotation of circular head screws. The screws used will advantageously be standardized screws.

On voit que grâce à l'invention, le passage d'un mode de raccordement à l'autre s'effectue avec les mêmes pièces, sans pièce intermédiaire.It can be seen that thanks to the invention, the transition from one connection mode to the other takes place with the same parts, without intermediate part.

Les différentes distances d'isolement électrique sont assurées par le couvercle. Le raccordement par barre est réalisé de manière simple, un seul outil étant nécessaire pour effectuer le serrage. On notera également la possibilité de changer les vis normalisées par d'autres (plus ou moins longues).The different electrical isolation distances are provided by the cover. The connection by bar is carried out in a simple way, only one tool being necessary for tighten. Note also the possibility of changing the standardized screws by others (more or less long).

Le boítier de l'appareil remplit plusieurs fonctions à savoir, le support des plages de raccordement, l'isolement des phases entre elles, et avec l'extérieur, la tenue en rotation des vis de raccordement barre, la fonction de couvercle des vis de fixation, le maintien des vis avant et en cours d'installation de l'appareil, le respect des distances d'isolement électrique par l'intermédiaire du couvercle.The housing of the device fulfills several functions, namely, the support of the ranges of connection, the isolation of the phases between them, and with the outside, the rotation resistance of the bar connection screw, cover screw fixing function, screw maintenance before and during installation of the device, compliance with the electrical isolation distances through the cover.

On notera également que le couvercle de vis est imperdable grâce à l'utilisation de la charnière intégrée.It will also be noted that the screw cover is captive thanks to the use of the integrated hinge.
