Abstract

The single face input and output method forms part of the modular electrical equipment (10). One side of the face (12) has holes (13N,13P) to access input connectors, whilst the other side has holes (15N,15P) to access output connectors. The input and output holes are separated by a partition wall (43), extending between the connection holes. Connection rails have protruding prongs which push into the holes, connecting to a feed rail which can pass above the partition wall.

Description

La présente invention concerne d'une manière générale les appareils électriques à bornes d'entrée et de sortie débouchant sur une même face de leur boítier, c'est-à-dire les appareils électriques comportant, sur cette face de leur boítier, d'une part, des trous, ou entrées de câbles, qui donnent accès à des bornes d'entrée, et, d'autre part, des trous, ou entrées de câbles, qui donnent accès à des bornes de sortie.The present invention relates generally electrical devices with input and output terminals opening onto the same side of their housing, that is to say the electrical appliances comprising, on this face of their housing, on the one hand, holes, or cable entries, which provide access to input terminals, and, on the other hand, holes, or cable entries, which provide access to terminals exit.

Un tel appareil électrique se trouve notamment décrit dans le brevet français qui, déposé le 21 décembre 1977, sous le No 77 38649, a été publié sous le No 2 375 740.Such an electrical appliance is notably described in the French patent which, filed on December 21, 1977, under No. 77 38649, was published under No. 2 375 740.

La présente invention vise plus particulièrement, mais non nécessairement exclusivement, le cas où, comme représenté dans ce brevet français No 77 38649, les appareils électriques concernés sont des appareils électriques modulaires, c'est-à-dire des appareils électriques dont le boítier présente, sous une forme générale parallélépipédique, deux faces principales parallèles, une face arrière, deux faces latérales et une face avant.The present invention relates more particularly, but not necessarily exclusively, the case where, as shown in this French patent No 77 38649, electrical appliances concerned are modular electrical devices, i.e. electrical appliances whose housing has, under a general parallelepiped shape, two main faces parallel, one rear side, two side faces and one side before.

Ces appareils électriques modulaires ont, globalement, un même contour, et la largeur, ou épaisseur, de leur boítier, c'est-à-dire la distance séparant l'une de l'autre les deux faces principales de ce boítier, est égale à un module de base commun à tous ou est un multiple de ce module de base.These modular electrical devices have, overall, the same outline, and the width, or thickness, of their housing, that is to say the distance separating one from the other the two main faces of this case, is equal to a basic module common to all or is a multiple of this basic module.

Il s'agit, par exemple, et cela est le cas dans le brevet français No 77 38649 mentionné ci-dessus, d'appareils électriques à protection différentielle, tels que des disjoncteurs ou des interrupteurs différentiels.This is, for example, and this is the case in the French patent No 77 38649 mentioned above, of apparatus differential protection electrics, such as circuit breakers or differential switches.

Quoi qu'il en soit, leurs bornes d'entrée comportent usuellement une borne de phase et une borne de neutre, et il en est de même de leurs bornes de sortie.Anyway, their input terminals have usually a phase terminal and a neutral terminal, and it the same is true of their output terminals.

Lorsque, sur les appareils électriques modulaires, les bornes d'entrée et les bornes de sortie sont classiquement réparties entre les deux faces latérales du boítier, les bornes d'entrée débouchant sur l'une de ces faces latérales tandis que les bornes de sortie débouchent sur l'autre de celles-ci, il est possible, lorsque ces appareils électriques sont disposés côte à côte sur un même support, d'en assurer conjointement, en parallèle, si désiré, une desserte commune, en mettant en oeuvre pour ce faire des barres d'alimentation, l'une de phase, l'autre de neutre, faisant office de barres bus et présentant, longitudinalement, de place en place, à cet effet, des dents établies à un pas régulier égal à leur module de base.When, on modular electrical devices, input terminals and the output terminals are conventionally distributed between the two side faces of the case, the terminals of entry leading to one of these side faces while the output terminals lead to each other, is possible, when these electrical devices are arranged side by side on the same support, to ensure jointly, in parallel, if desired, a common service, putting in works to do this power bars, one of phase, the other neutral, serving as bus bars and presenting, longitudinally, from place to place, for this purpose, teeth established at a regular step equal to their basic module.

Lorsque, à de tels appareils électriques modulaires, il est associé un appareil électrique, et, par exemple, un appareil électrique à protection différentielle, dont les bornes d'entrée et les bornes de sortie débouchent sur une même face du boítier, en l'espèce une face latérale de celui-ci, et que, de manière traditionnelle, les bornes de phase de cet appareil électrique sont établies à un même niveau que celui des autres appareils électriques, ses bornes de neutre étant elles-mêmes établies à niveau qui, différent du précédent, est aussi le même que celui auquel sont établies les bornes de neutre de ces derniers, il y a le risque que, par inadvertance, et de manière intempestive, la barre d'alimentation de phase soit conjointement engagée par deux dents distinctes dans les bornes de phase d'un tel appareil électrique à protection différentielle, et/ou qu'il en soit de même pour la barre d'alimentation de neutre, ce qui conduirait à un bouclage sur lui-même de cet appareil électrique à protection différentielle, et, donc, à sa mise hors service, voire, même, à sa détérioration, au détriment de la sécurité recherchée.When, in such modular electrical devices, it is associated with an electrical appliance, and, for example, a differential protection electrical appliance, the input terminals and the output terminals lead to the same face of the case, in this case a side face thereof, and that, in a traditional way, the phase bounds of this electrical appliance are established at the same level as that other electrical devices, its neutral terminals being themselves established at a level which, different from the previous one, is also the same as that at which the limits of neutral of these, there is the risk that inadvertently, and inadvertently, the phase power bar either jointly engaged by two separate teeth in the phase terminals of such an electrical protection device differential, and / or the same for the bar neutral supply, which would lead to a loopback on itself from this protective electrical device differential, and therefore, when it is taken out of service, or even to its deterioration, to the detriment of the security sought.

La présente invention a d'une manière générale pour objet une disposition permettant d'éliminer de manière très simple un tel risque.The present invention generally has for subject a provision to eliminate very simple such a risk.

De manière plus précise, elle a pour objet un appareil électrique du genre comportant, sur une même face de son boítier, d'une part, des trous qui donnent accès à des bornes d'entrée, et, d'autre part, des trous qui donnent accès à des bornes de sortie, et auquel il est associé, pour sa desserte, une barre d'alimentation qui présente, de place en place, des dents issues d'une même longrine, cet appareil électrique étant d'une manière générale caractérisé en ce que, le boítier présentant, en saillie, sur sa face concernée, entre les trous donnant accès aux bornes d'entrée et ceux donnant accès aux bornes de sortie, une paroi de séparation, la largeur de cette paroi de séparation, mesurée à compter des bornes d'entrée et de sortie, perpendiculairement à la face concernée du boítier, est au moins égale à la hauteur des dents de la barre d'alimentation.More specifically, it relates to a device electric of the kind comprising, on the same face of its housing, on the one hand, holes which give access to terminals entry, and, on the other hand, holes which give access to output terminals, and with which it is associated, for its service, a power bar that presents, from place to place, teeth from the same sill, this electrical device being generally characterized in that, the housing having, projecting, on its face concerned, between the holes giving access to the input terminals and those giving access to output terminals, a partition wall, the width of this partition wall, measured from the input terminals and outlet, perpendicular to the relevant face of the housing, is at least equal to the height of the bar teeth Power.

La paroi de séparation ainsi prévue suivant l'invention s'oppose systématiquement, et efficacement, à l'engagement simultané de deux dents d'une même barre d'alimentation dans une borne d'entrée et une borne de sortie.The partition wall thus provided according to the invention is systematically, and effectively, opposed to the simultaneous engagement of two teeth of the same bar supply to an input terminal and an output terminal.

Ainsi, tout risque de bouclage sur lui-même de l'appareil électrique à ce niveau par cette barre d'alimentation se trouve avantageusement évité.Thus, any risk of looping in on itself the electrical appliance at this level by this bar feed is advantageously avoided.

Certes, dans la demande de brevet français No FR 2 588 998 A, il est décrit un appareil électrique présentant des parois de séparation entre les trous donnant accès à certaines de ses bornes.Certainly, in the French patent application No. FR 2 588 998 A, an electrical appliance is described having partition walls between the holes giving access to some of its terminals.

Mais, dans cette demande de brevet français No FR 2 588 998 A, il n'est pas prévu que la desserte de l'appareil électrique concerné se fasse par une barre d'alimentation en forme de peigne, et, a fortiori, il n'est donné aucune indication sur la largeur, par rapport à la hauteur des dentes de ce peigne, des parois de séparation qu'il présente.But, in this French patent application No FR 2 588 998 A, it is not intended that the service of the electrical appliance concerned is made by a bar comb-shaped feed, and a fortiori, it is not given no indication of the width, in relation to the height of the teeth of this comb, the partition walls it present.

Il en est de même dans le brevet américain No US 5 315 068 A, qui, par ailleurs, vise un tout autre objet que celui de la présente invention.It is the same in the American patent No. 5,315,068 A, which, moreover, relates to a completely different object than that of the present invention.

Les caractéristiques et avantages de la présente invention ressortiront d'ailleurs de la description qui va suivre, à titre d'exemple, en référence aux dessins schématiques annexés sur lesquels :

  • la figure 1 est une vue en perspective d'un appareil électrique suivant l'invention ;
  • la figure 2 en est une vue en plan, suivant la flèche II de la figure 1, avec mise en oeuvre d'une barre d'alimentation faisant office de barre bus ;
  • la figure 3 est une vue partielle en perspective d'une variante de réalisation de cette barre d'alimentation.
    • The characteristics and advantages of the present invention will become apparent from the description which follows, by way of example, with reference to the appended schematic drawings in which:
  • Figure 1 is a perspective view of an electrical device according to the invention;
  • Figure 2 is a plan view, along arrow II of Figure 1, with the implementation of a power bar acting as a bus bar;
  • Figure 3 is a partial perspective view of an alternative embodiment of this feed bar.

    • Ces figures illustrent, à titre d'exemple, l'application de l'invention à un appareil électrique 10 à protection différentielle du type de celui représenté dans le brevet français No 77 38649 mentionné ci-dessus.These figures illustrate, by way of example, application of the invention to an electrical appliance 10 to differential protection of the type shown in the French patent No 77 38649 mentioned above.

    Cet appareil électrique 10 ne relevant pas par lui-même de la présente invention, il ne sera pas décrit dans tous ses détails ici.This electrical device 10 not falling by itself of the present invention, it will not be described in all its details here.

    Seuls en seront décrits les éléments nécessaires à la compréhension de l'invention.Only the elements necessary for the understanding of the invention.

    Il suffira, à ce sujet, d'indiquer qu'il comporte un boítier 11, en pratique en matière isolante, avec, sur une face 12 de ce boítier 11, d'une part, des trous 13P, 13N qui, chacun respectivement, donnent accès à des bornes d'entrée 14P, 14N internes au boítier 11, et, d'autre part, des trous 15P, 15N qui, chacun respectivement, donnent eux-mêmes accès à des bornes de sortie 16P, 16N elles aussi internes à ce boítier 11.It will suffice, in this regard, to indicate that it includes a housing 11, in practice in insulating material, with, on one side 12 of this housing 11, on the one hand, holes 13P, 13N which, each respectively, give access to input terminals 14P, 14N internal to the housing 11, and, on the other hand, holes 15P, 15N which, each respectively, themselves provide access to output terminals 16P, 16N also internal to this housing 11.

    Pour ne pas surcharger inutilement la figure 1, seule l'une de ces bornes d'entrée 14P, 14N et de sortie 16P, 16N, en l'espèce la borne d'entrée 14P, a été schématisée en tirets sur cette figure 1.To avoid unnecessarily overloading Figure 1, only one of these input terminals 14P, 14N and output 16P, 16N, in this case the input terminal 14P, has been shown schematically in dashes in this figure 1.

    Mais ces bornes d'entrée 14P, 14N et de sortie 16P, 16N apparaissent toutes, en tirets sur la figure 2, sur laquelle, de surcroít, est visible, en plan, la tête 17 de leur vis de serrage 18.But these input terminals 14P, 14N and output 16P, 16N all appear, in dashes in FIG. 2, on which, moreover, is visible in plan, the head 17 of their clamping screw 18.

    Ces bornes d'entrée 14P, 14N et de sortie 16P, 16N ont toutes une constitution identique, et, celle-ci relevant des dispositions usuelles en la matière, elles ne seront pas décrites ici.These input terminals 14P, 14N and output 16P, 16N have all an identical constitution, and, this one falling under usual provisions in the matter, they will not be described here.

    Dans la forme de réalisation représentée, l'appareil électrique 10 est un appareil électrique modulaire.In the embodiment shown, the apparatus Electric 10 is a modular electric device.

    Son boítier 11 présente donc, sous une forme générale parallélépipédique, deux faces principales 20, qui sont parallèles entre elles, et, reliant l'une à l'autre ces deux faces principales 20 suivant sa tranche, une face arrière 21, deux faces latérales 12 et une face avant 22, qui sont toutes perpendiculaires aux faces principales 20.Its housing 11 therefore has, in a general form parallelepiped, two main faces 20, which are parallel to each other, and, connecting these two to each other main faces 20 along its edge, a rear face 21, two side faces 12 and a front face 22, which are all perpendicular to the main faces 20.

    Pour la fixation de l'ensemble à un quelconque support, en pratique un rail normalisé non représenté, la face arrière 21 présente, dans sa zone médiane, une échancrure 23.For fixing the assembly to any support, in practice a standard rail not shown, the face rear 21 has, in its middle zone, a notch 23.

    Les deux faces latérales 12 sont sensiblement perpendiculaires à la face arrière 21, et c'est sur l'une d'elles que débouchent, conjointement, les trous 13P, 13N donnant accès aux bornes d'entrée 14P, 14N et ceux 15P, 15N donnant accès aux bornes de sortie 16P, 16N.The two lateral faces 12 are substantially perpendicular to the rear face 21, and this is on one from which the 13P, 13N holes jointly open giving access to the input terminals 14P, 14N and those 15P, 15N giving access to the output terminals 16P, 16N.

    La face avant 22, enfin, présente, dans sa partie médiane, une partie saillante 24, sur laquelle intervient une manette 25 à la disposition de l'usager, et, disposées chacune respectivement de part et d'autre de cette partie saillante 24, deux facettes latérales 26, qui, établies à un même niveau, sont l'une et l'autre sensiblement parallèles à la face arrière 21.The front face 22, finally, presents, in its part median, a projecting part 24, on which a controller 25 available to the user, and, each arranged respectively on either side of this projecting part 24, two lateral facets 26, which, established at the same level, are both substantially parallel to the rear face 21.

    Celle de ces faces latérales 26 qui se trouve à l'aplomb des bornes d'entrée 14P, 14N et des bornes de sortie 16P, 16N présente, en correspondance avec celles-ci, des trous 27P, 27N, 28P, 28N, pour donner accès à la tête 17 de leur vis de serrage 18.That of these lateral faces 26 which is located at plumb with input terminals 14P, 14N and output terminals 16P, 16N has, in correspondence with them, holes 27P, 27N, 28P, 28N, to give access to the head 17 of their screw tightening 18.

    La largeur E, ou épaisseur, du boítier 11, mesurée de l'une à l'autre de ses deux faces principales 20, est égale au double d'un module de base M commun à tous les appareils électriques modulaires, non représentés, auxquels peut être associé l'appareil électrique 10.The width E, or thickness, of the housing 11, measured from to each other of its two main faces 20, is equal to double a basic module M common to all devices modular electrics, not shown, which can be associated the electrical appliance 10.

    Sur la face 12 concernée de ce boítier 11, en l'espèce une face latérale de celui-ci, les trous 13P et 15P sont établis à un même niveau, en étant écartés l'un de l'autre d'une distance P égale au module de base M.On the face 12 concerned of this housing 11, in this case a side face of it, the holes 13P and 15P are established at the same level, being separated from each other a distance P equal to the basic module M.

    Les bornes d'entrée 14P et de sortie 16P auxquelles ils correspondent sont par exemple des bornes de phase.The 14P input and 16P output terminals to which they correspond, for example, to phase terminals.

    De même, les trous 13N et 15N sont établis à un même niveau, distinct du précédent, en étant eux aussi écartés l'un de l'autre d'une distance P égale au module de base M.Similarly, holes 13N and 15N are established at the same level, distinct from the previous one, being also discarded one on the other by a distance P equal to the basic module M.

    Les bornes d'entrée 14N et de sortie 16N auxquelles ils correspondent sont par exemple des bornes de neutre. The 14N input and 16N output terminals at which they correspond, for example, to neutral terminals.

    En pratique, et tel que représenté, les trous 13N et 15N sont chacun respectivement décalés par rapport aux trous 13P et 15P, parallèlement à la face arrière 21 du boítier 11, d'une distance P' égale à la moitié du module de base M, et ils s'étendent entre les trous 13P et 15P et la face arrière 21 du boítier 11.In practice, and as shown, the holes 13N and 15N are each respectively offset from the holes 13P and 15P, parallel to the rear face 21 of the housing 11, of a distance P 'equal to half of the basic module M, and they extend between holes 13P and 15P and the rear face 21 of the housing 11.

    Par exemple, et tel que représenté, les trous 13P, 13N, 15P, 15N ont un contour globalement rectangulaire, tandis que les trous 27P, 27N, 28P, 28N ont un contour globalement circulaire.For example, and as shown, the holes 13P, 13N, 15P, 15N have a generally rectangular outline, while that the holes 27P, 27N, 28P, 28N have an outline overall circular.

    Les dispositions qui précèdent ne relèvent pas de la présente invention, et elles ne seront donc pas décrites plus en détail ici.The foregoing provisions are not part of the present invention, and they will therefore not be described further in detail here.

    Suivant des dispositions qui ne relèvent pas non plus de la présente invention, le boítier 11 comporte un socle 30, qui forme l'une de ses faces principales 20, et un capot 31, qui, d'un seul tenant avec la face avant 22, forme l'autre de ces faces principales 20, avec, entre ce socle 30 et ce capot 31, sensiblement à mi-distance entre les faces principales 20, une cloison isolante 32, qui s'étend parallèlement aux faces principales 20, de l'une à l'autre des faces latérales 12, entre la face arrière 21 et les facettes latérales 26 de la face avant 22.According to provisions which do not fall either of the present invention, the housing 11 comprises a base 30, which forms one of its main faces 20, and a cover 31, which, in one piece with the front face 22, forms the other of these main faces 20, with, between this base 30 and this cover 31, substantially midway between the main faces 20, an insulating partition 32, which extends parallel to the faces main 20, from one to the other of the side faces 12, between the rear face 21 and the side facets 26 of the front panel 22.

    Dans la forme de réalisation représentée, entre le socle 30 et la cloison isolante 32 intervient un bornier 33, qui regroupe les bornes de sortie 16P, 16N, et, de même, entre cette cloison isolante 32 et le capot 31 intervient un bornier 34, qui regroupe les bornes d'entrée 14P, 14N.In the embodiment shown, between the base 30 and the insulating partition 32 intervenes a terminal block 33, which groups the output terminals 16P, 16N, and, similarly, between this insulating partition 32 and the cover 31 intervenes a terminal block 34, which groups the input terminals 14P, 14N.

    En plan, et tel que visible sur la figure 2, les bornes d'entrée 14P, 14N et les bornes de sortie 16P, 16N sont globalement alignées les unes avec les autres.In plan, and as visible in Figure 2, the input terminals 14P, 14N and the output terminals 16P, 16N are globally aligned with each other.

    Suivant l'invention, le boítier 11 présente, en saillie sur sa face 12 concernée par les trous 13P, 13N, 15P, 15N, en l'espèce l'une de ses faces latérales 12, une paroi de séparation 35.According to the invention, the housing 11 has, in projection on its face 12 concerned by the holes 13P, 13N, 15P, 15N, in this case one of its lateral faces 12, a wall of separation 35.

    Dans la forme de réalisation représentée, cette paroi de séparation 35 est sensiblement perpendiculaire à la face 12 concernée du boítier 11 et elle s'étend parallèlement aux faces principales 20 de celui-ci.In the embodiment shown, this wall separation 35 is substantially perpendicular to the face 12 concerned of the housing 11 and it extends parallel to the faces main 20 of it.

    Dans cette forme de réalisation, la paroi de séparation 35 ne s'étend en fait que sur une fraction de la hauteur de la face 12 concernée du boítier 11.In this embodiment, the wall of separation 35 actually only spans a fraction of the height of the relevant face 12 of the housing 11.

    Autrement dit, sa hauteur H', mesurée à sa racine, suivant la face 12 concernée du boítier 11, est largement inférieure à celle H de cette face 12, mesurée de la face arrière 21 du boítier 11 à la facette latérale 26 correspondante de la face avant 22 de celui-ci.In other words, its height H ', measured at its root, along the face 12 concerned of the housing 11, is largely less than that H of this face 12, measured from the face rear 21 of the housing 11 to the side facet 26 corresponding to the front face 22 thereof.

    Dans la forme de réalisation représentée, la paroi de séparation 35 a un contour globalement rectangulaire.In the embodiment shown, the wall of partition 35 has a generally rectangular outline.

    Mais, préférentiellement, et tel que représenté, ses zones d'angle libres 36, c'est-à-dire celles de ses zones d'angle qui sont à distance de la face 12 concernée du boítier 11, sont adoucies, par exemple par un arrondi 37.But, preferably, and as shown, its free angle zones 36, i.e. those of its zones of angle which are at a distance from the face 12 concerned of the case 11, are softened, for example by a rounding 37.

    En outre, dans la forme de réalisation représentée, la paroi de séparation 35 se présente sous la forme générale d'une plaquette mince, dont l'épaisseur E', mesurée perpendiculairement aux faces principales 20 du boítier 11, est relativement faible, en étant cependant suffisante à sa bonne tenue mécanique.Furthermore, in the embodiment shown, the partition wall 35 is in the general form of a thin wafer, whose thickness E ', measured perpendicular to the main faces 20 of the housing 11, is relatively weak, being however sufficient for its good mechanical strength.

    Comme représenté à la figure 2, il est associé, à l'appareil électrique 10, pour sa desserte, une barre d'alimentation 38 présentant, de place en place, suivant un pas P régulier, des dents 39 par lesquelles elle est apte à être engagée dans une quelconque borne d'entrée 14P, 14N ou de sortie 16P, 16N.As shown in Figure 2, it is associated with the electrical appliance 10, for its service, a bar supply 38 having, from place to place, following a step P regular, teeth 39 by which it is able to be engaged in any input terminal 14P, 14N or exit 16P, 16N.

    Sur la figure 2, les dents 39 de cette barre d'alimentation 38 sont droites, à la manière de celles d'un peigne.In Figure 2, the teeth 39 of this bar 38 are straight, like those of a comb.

    En variante, figure 3, elles sont coudées, en présentant toutes, à un même niveau, un coude 40.As a variant, in FIG. 3, they are bent, in all having, at the same level, an elbow 40.

    Dans l'un et l'autre cas, elles sont toutes issues d'une même longrine 41.In both cases, they all stem from of the same sill 41.

    Dans la forme de réalisation représentée sur la figure 3, cette longrine 41 est munie d'un revêtement 42 en matière isolante.In the embodiment shown in the figure 3, this sill 41 is provided with a coating 42 of material insulating.

    Suivant l'invention, la largeur L'1 de la paroi de séparation 35 mesurée à compter des bornes d'entrée 14P, 14N et de sortie 16P, 16N, perpendiculairement à la face 12 concernée du boítier 11, c'est-à-dire à la face latérale 12 de ce boítier 11 sur laquelle elle fait saillie, est au moins égale à la hauteur L des dents 39 de cette barre d'alimentation 38 mesurée à compter de la longrine 41.According to the invention, the width L'1 of the wall of separation 35 measured from input terminals 14P, 14N and output 16P, 16N, perpendicular to face 12 concerned of the housing 11, that is to say on the side face 12 of this housing 11 on which it projects, is at least equal to the height L of the teeth 39 of this feed bar 38 measured from sill 41.

    Lorsque les dents 39 sont droites, leur hauteur L se confond avec leur longueur.When the teeth 39 are straight, their height L is confuses with their length.

    Lorsque les dents 39 sont coudées, leur hauteur L ne correspond qu'à la longueur de leur extrémité droite.When the teeth 39 are bent, their height L does not corresponds only to the length of their right end.

    Cette hauteur L doit en effet être alors appréciée en ligne droite, parallèlement à la longueur des dents 39, comme lorsque celles-ci sont droites.This height L must indeed be then appreciated in straight line, parallel to the length of the teeth 39, as when these are straight.

    Autrement dit, la hauteur L des dents 39 doit dans tous les cas être appréciée en projection sur un plan qui, passant par la longrine 41, est parallèle à l'extrémité droite de ces dents 39.In other words, the height L of the teeth 39 must in all cases be assessed in projection on a plane which, passing through the sill 41, is parallel to the right end of these teeth 39.

    Préférentiellement, et par mesure de sécurité, la largeur L'2 de la paroi de séparation 35, mesurée à compter de la face 12 concernée du boítier 11, est au moins égale à la hauteur L des dents 39 de la barre d'alimentation 38, tel que représenté.Preferably, and for security reasons, the width L'2 of the partition wall 35, measured from the face 12 concerned of the housing 11, is at least equal to the height L of the teeth 39 of the feed bar 38, such as represented.

    Conjointement, la distance D' entre, d'une part, le bord supérieur 43 de la paroi de séparation 35, c'est-à-dire le bord transversal de cette paroi de séparation 35 la plus proche de la face avant 22 du boítier 11, ou, plus précisément, de la facette latérale 26 correspondante de celle-ci, et, d'autre part, le bord supérieur 44 correspondant des trous 13P, 13N, 15P, 15N les plus proches de cette face avant 22 appréciée dans les mêmes conditions est supérieure à la distance D entre, d'une part, le coude 40 des dents 39 de la barre d'alimentation 38, et, d'autre part, la longrine 41 dont sont issues ces dents 39.Jointly, the distance D 'between, on the one hand, the upper edge 43 of the partition wall 35, that is to say the transverse edge of this dividing wall 35 most close to the front face 22 of the housing 11, or, more precisely, of the corresponding lateral facet 26 thereof, and, on the other hand, the corresponding upper edge 44 of the holes 13P, 13N, 15P, 15N closest to this front face 22 appreciated under the same conditions is greater than the distance D between, on the one hand, the elbow 40 of the teeth 39 of the feed bar 38, and, on the other hand, the sill 41 from which these teeth originate 39.

    Dans la forme de réalisation représentée, la paroi de séparation 35 est d'un seul tenant avec le boítier 11. In the embodiment shown, the wall of separation 35 is in one piece with the housing 11.

    Plus précisément, dans cette forme de réalisation, elle est d'un seul tenant avec la cloison isolante 32 que comporte ce boítier 11.More specifically, in this embodiment, it is in one piece with the insulating partition 32 that includes this housing 11.

    Quoi qu'il en soit, formant, géométriquement, par son contour, un obstacle entre les trous 13P, 13N et les trous 15P, 15N, la paroi de séparation 35 suivant l'invention s'oppose systématiquement à un engagement simultané de deux dents 39 d'une même barre d'alimentation 38 dans la borne d'entrée 14P et dans la borne de sortie 16P, ou dans la borne d'entrée 14N et dans la borne de sortie 16N, qu'il s'agisse de dents 39 droites ou qu'il s'agisse de dents 39 coudées.Anyway, forming, geometrically, by its contour, an obstacle between holes 13P, 13N and holes 15P, 15N, the partition wall 35 according to the invention opposes systematically to a simultaneous engagement of two teeth 39 of the same power bar 38 in the input terminal 14P and in the output terminal 16P, or in the input terminal 14N and in the output terminal 16N, whether teeth 39 straight or it is bent 39 teeth.

    En outre, son domaine d'application n'est pas nécessairement limité à celui des seuls appareils électriques à protection différentielle, mais peut s'étendre aussi bien à celui de tous les appareils électriques présentant sur une même face des bornes d'entrée et des bornes de sortie.Furthermore, its field of application is not necessarily limited to that of electrical appliances only with differential protection, but can extend as well to that of all electrical devices presenting on the same face of the input terminals and output terminals.
