The tooth is guided when it is plugged in. The wall is opposite to a wall receiving a screw (2). The blade is in the form of a loop surrounding the ring wall. An opening of the loop is oriented in an extension for inserting the ring.

Description

La présente invention concerne un dispositif de connexion double pour appareils électriques de type modulaire, par exemple des disjoncteurs, en vue du raccordement simultané d'au moins un conducteur et d'une dent d'une barre de pontage, au moyen respectivement d'un ensemble à cage et vis et d'un système de connexion rapide à lame ressort.The present invention relates to a dual connection device for modular-type electrical appliances, for example circuit-breakers for the simultaneous connection of at least one conductor and tooth of a bridging bar, using respectively of a cage and screw assembly and a system of quick connection to spring blade.

L'association de ces deux types de connecteur, dans de tels appareils électriques, est déjà connue. Ainsi, dans le modèle d'utilité allemand référencé DE29916001, il est décrit une configuration dans laquelle un dispositif de connexion à cage et vis surmonte un système d'enfichage rapide basé sur une lame ressort en forme de lyre, qui se situe à proximité de la semelle de fixation de l'appareil modulaire à un rail standardisé. De même, la demande de brevet Européen référencée EP1028489 divulgue une structure dans laquelle l'ensemble cage / vis est situé à proximité de la semelle de fixation et surmontée par un système à enfichage à lame ressort, ladite lame coopérant avec une borne par ailleurs intégrée dans la cage. Dans ce cas, la problématique que cherche notamment à résoudre l'invention est de permettre l'accès à la vis malgré l'existence du système à enfichage rapide qui la surmonte.The combination of these two types of connector, in such electrical appliances, is already known. So, in the utility model German referenced DE29916001, it is described a configuration in which a cage and screw connection device overcomes a system rapid insertion based on a spring blade in the shape of a lyre, which located near the mounting plate of the modular device to a standardized rail. Similarly, the referenced European patent application EP1028489 discloses a structure in which the cage / screw assembly is located near the attachment footing and surmounted by a spring-loaded plug-in system, said blade cooperating with a terminal also integrated in the cage. In this case, the problem that seeks to solve the invention is to allow access to the screw despite the existence of the quick-plug system that overcomes it.

Ces deux configurations, utilisant les mêmes types de connecteur que la présente invention, ne présentent cependant pas les caractéristiques leur permettant de résoudre le problème particulier posé dans le cadre de ladite invention. Celui-ci concerne l'implantation d'une telle double structure de connexion dans un espace réduit, dont l'exiguïté n'offre guère de liberté pour le positionnement des connecteurs.These two configurations, using the same types of connector that the present invention, however, do not present the features allowing them to solve the particular problem posed in the context of said invention. This concerns the implantation of such double connection structure in a small space, the small size of which does not offer much of freedom for the positioning of the connectors.

Le cas se présente notamment dans les disjoncteurs phase-neutre, car les moyens de connexion y sont décalés pour la phase et pour le neutre, conduisant à un volume d'implantation beaucoup plus réduit pour les moyens disposés les plus proches de la façade du produit. Le décalage résulte notamment du fait que les barres de pontage doivent nécessairement être décalées pour pouvoir être installées. Le choix de leur niveau d'implantation, que l'on appelle aussi le niveau de pontage du produit, n'est donc pas libre, d'autant moins qu'il convient également de respecter une compatibilité avec les autres produits de la gamme, susceptibles de se retrouver fixés sur le même rail standard, et dès lors connectés via les mêmes barres de pontage.This is particularly the case in phase-neutral circuit breakers because the means of connection are shifted for the phase and for the neutral, leading to a much smaller implantation volume for the most arranged means close to the front of the product. The difference is due in particular to the fact that bridging bars must necessarily be shifted in order to be installed. The choice of their level of implantation, which is also called the level bridging the product, is not free, especially since it is also appropriate to be compatible with other products in the range, likely to to be fixed on the same standard rail, and therefore connected via the same bridging bars.

En d'autres termes, le niveau de pontage étant imposé, on se retrouve à devoir implanter dans un volume limité par ledit niveau d'une part, et la façade du produit d'autre part, un système de connexion double, sachant que le positionnement de la façade n'est pas non plus modifiable pour permettre la pose du plastron dans le coffret.In other words, the level of bridging being imposed, we end up having to implant in a limited volume by said level on the one hand, and the front of the product on the other hand, a double connection system, knowing that the positioning of the facade is also not modifiable to allow the installation of the plastron in the box.

Pour compléter les contraintes à prendre en compte, il faut noter encore que les connecteurs à cage et vis, ayant pour fonction de permettre l'alimentation ou le repiquage, sont par conséquent implantés plus proches de la façade afin que les manipulations effectuées par l'opérateur ne soient pas gênées par des barres de pontage qui seraient, dans l'hypothèse de positionnement inverse, interposées entre eux et la façade. Or, les règles de sécurité imposent une protection des parties sous tension, en l'occurrence la tête de vis, qui nécessite que celle-ci soit suffisamment noyée à l'intérieur du boítier. Une portion du volume est donc réservée à cet effet.To complete the constraints to be taken into account, it should be noted that cage and screw connectors, the function of which is to provide power or transplanting, are therefore located closer to the facade so that manipulations made by the operator are not hampered by bridging which would be, in the event of reverse positioning, interposed between them and the facade. However, the safety rules impose a protection of parts under tension, in this case the screw head, which requires that it be sufficiently embedded inside the housing. A portion of the volume is therefore reserved for this purpose.

Au final, du côté où les moyens de connexion sont les plus proches de la façade, le volume disponible ne permet pas l'implantation des configurations de l'art antérieur précitées. L'invention propose par conséquent une nouvelle structure, qui fait abstraction des modèles existants, et permet la double implantation sans porter atteinte au bon fonctionnement électrique.In the end, on the side where the means of connection are closest to the facade, the available volume does not allow the implementation of the configurations of the aforementioned prior art. The invention therefore proposes a new structure, which abstracts from existing models, and allows for dual implementation without impair the proper electrical operation.

A titre principal, selon l'invention, il convient que la lame ressort du système de connexion rapide coopère avec la cage du connecteur traditionnel à cage / vis de telle sorte que la dent de la barre de pontage, lorsqu'elle est enfichée, est guidée au contact ou au voisinage immédiat de la surface extérieure de la paroi de la cage opposée à la paroi qui reçoit la vis.As a main feature, according to the invention, the blade should spring from the system of fast connection cooperates with the cage of the traditional connector with cage / screw of so that the tooth of the bridging bar, when plugged in, is guided in contact with or in the immediate vicinity of the outer surface of the cage wall opposite to the wall that receives the screw.

En d'autres termes, la gestion du volume est optimisée de telle sorte que les deux organes de connexion soient accolés l'un à l'autre, sous une forme qui remplit une double fonction mécanique et électrique, assurant d'une part le guidage de la dent et d'autre part la distribution du courant de l'un à l'autre.In other words, volume management is optimized so that two connecting members are joined to each other, in a form that fills a double mechanical and electrical function, ensuring on the one hand the guiding of the tooth and on the other hand the distribution of the current from one to the other.

Ainsi, selon une configuration possible, on prévoit que la lame ressort forme une boucle entourant ladite paroi, qui est de fait celle qui est la plus proche de la semelle, l'ouverture de la boucle étant ensuite orientée parallèlement à et sensiblement dans le prolongement de l'ouverture d'insertion de la cage.Thus, in one possible configuration, it is expected that the leaf spring forms a loop surrounding said wall, which is actually the one that is closest to the sole, the opening of the loop being then oriented parallel to and substantially in the extension of the insertion opening of the cage.

Dans tous les cas, l'ouverture de la boucle doit se situer à l'extérieur de la cage, mais à l'intérieur du boítier.In all cases, the opening of the loop must be located outside the cage, but inside the case.

La forme particulière donnée à la boucle lui permet également d'assurer une double fonction, à la fois électrique et mécanique. Dans le registre mécanique, cette boucle doit permettre l'enfichage et la rétention d'une dent d'un peigne de pontage, sans que des efforts ne soient nécessairement transmis à la cage.The particular shape given to the loop also allows it to ensure a dual function, both electrical and mechanical. In the mechanical register, this loop shall permit the insertion and retention of a tooth of a bridging comb, without any effort being necessarily transmitted to the cage.

Elle comporte notamment des tronçons d'extrémité s'évasant vers l'ouverture du boítier et se resserrant vers l'ouverture de la boucle. L'insertion, puis le maintien ne sont d'ailleurs possibles que grâce à l'élasticité de la boucle, alliée à la forme particulière donnée aux dites extrémités, qui facilitent le guidage à l'insertion et constituent par conséquent une partie importante de la boucle.It includes end sections flaring towards the opening housing and tightening towards the opening of the loop. Inserting and then maintaining are only possible thanks to the elasticity of the loop, allied to the shape peculiarity given to the said ends, which facilitate the guiding at the insertion and therefore constitute an important part of the loop.

La forme de la boucle n'est pas séparable de celle de la cage, ces éléments devant de plus être conçus en relation avec le boítier. Pour assurer un enfichage correct et complet des barres de pontage, il faut notamment que la totalité de la boucle soit implantée à l'intérieur du volume du boítier. Pour permettre un positionnement correct des tronçons d'extrémités, compte tenu de leur fonction et de leur proximité avec la partie inférieure de la cage, cette dernière subit de préférence une modification.The shape of the loop is not separable from that of the cage, these elements before being designed in connection with the housing. To insure a plug-in correct and complete bridging bars, it is necessary that the whole of the loop is implanted inside the volume of the housing. To allow a correct positioning of the end sections, taking into account their function and their proximity to the lower part of the cage, the latter undergoes preferably a modification.

Ainsi, au moins la paroi de la cage opposée à celle qui reçoit la vis est de préférence réduite en surface, du côté de l'insertion des conducteurs, pour dégager de l'espace à cet effet.Thus, at least the wall of the cage opposite to that which receives the screw is reduced surface preference, on the insertion side of the conductors, to clear space for this purpose.

Sur un plan électrique, la forme en boucle permet un double contact sur la dent du peigne de pontage qui y est enfiché. Ce double contact autorise l'emploi d'une section réduite pour la lame ressort, calculée pour véhiculer une partie de l'intensité maximale du courant transportée par le ou les conducteurs connectés à l'ensemble à cage et vis. On an electrical plane, the loop shape allows a double contact on the tooth the bridging comb that is plugged into it. This double contact allows the use of a reduced section for the leaf spring, calculated to convey part of the intensity the current carried by the connected conductor or conductors cage and screw.

La forme en boucle permet en fait un gain de matière, et par conséquent d'encombrement, qui nécessite cependant l'existence du rebouclage électrique.The loop shape actually allows a gain of material, and therefore of space, which however requires the existence of the electrical loopback.

Dans cette configuration, la partie de la boucle disposée à l'intérieur de la cage sert de borne à cette dernière, contribuant à l'optimisation de la double connexion.In this configuration, the part of the loop disposed inside the cage serves as a terminal to the latter, contributing to the optimization of the dual connection.

Selon une possibilité, la liaison électrique avec le noyau fonctionnel de l'appareil électrique est solidaire de la lame ressort. Plus précisément, cette liaison peut être prévue d'une seule pièce avec la lame ressort, et se développer à partir d'une portion médiane de la boucle située à l'opposé de son ouverture.According to one possibility, the electrical connection with the functional core of the apparatus electric is integral with the leaf spring. More specifically, this link can be planned in one piece with the leaf spring, and develop from a middle portion of the loop located opposite its opening.

L'invention présente par ailleurs une variante qui consiste en une configuration dans laquelle la lame ressort est fixée à un support solidaire de la cage de telle sorte que son extrémité libre soit plaquée contre la surface extérieure de la paroi de la cage opposée à la paroi qui reçoit la vis. La lame sert dans ce cas à plaquer la dent de la barre de pontage contre la cage, qui doit alors être conductrice.The invention also has a variant which consists of a configuration in which the leaf spring is fixed to a support integral with the cage of such so that its free end is pressed against the outer surface of the wall the cage opposite the wall that receives the screw. In this case, the blade is used to tooth of the bridging bar against the cage, which must then be conductive.

De préférence, ledit support est constitué en forme de L prolongeant l'une des parois latérales de la cage et dont la base, sur laquelle est fixée la lame ressort, est parallèle à la paroi contre laquelle est plaquée son extrémité libre.Preferably, said support is formed in the shape of an L extending one of the side walls of the cage and whose base, on which is fixed the blade spring, is parallel to the wall against which is plated its free end.

En d'autres termes, ladite variante peut être considérée comme la superposition de deux cages, la cage à vis et une cage tronquée supportant la lame ressort. Dans ce cas, et à l'inverse de la configuration précédente, la lame ressort n'a pas besoin d'être conductrice. Il s'ensuit une plus grande souplesse dans le choix du matériau de la lame ressort, qui est de plus en général moins onéreux que dans une version conductrice.In other words, said variant can be considered as the superposition two cages, the screw cage and a truncated cage supporting the blade spring. In this case, and unlike the previous configuration, the spring blade does not have need to be a driver This results in greater flexibility in the choice of material of the spring blade, which is more generally less expensive than in a conductive version.

L'invention va à présent être décrite plus en détail, en référence aux figures, pour lesquelles :

  • la figure 1 est une vue en perspective de la première variante selon l'invention ;
  • la figure 2 représente une portion d'un disjoncteur muni d'un dispositif de connexion double selon l'invention ; et
  • la figure 3 montre une seconde variante de connecteur double.
The invention will now be described in more detail, with reference to the figures, for which:
  • Figure 1 is a perspective view of the first variant of the invention;
  • FIG. 2 represents a portion of a circuit breaker provided with a double connection device according to the invention; and
  • Figure 3 shows a second variant of double connector.

En référence à la figure 1, le dispositif de connexion double selon l'invention se compose, en partie supérieure, d'un mécanisme traditionnel à cage (1) et vis (2) auquel est adjoint un système de connexion rapide à lame ressort en forme de boucle (3). Les direction et sens d'insertion des conducteurs d'une part, et des dents des barres de raccordement d'autre part, sont indiqués respectivement par les flèches A et B. Le fonctionnement du connecteur à cage (1) et vis (2) étant classique, il n'est pas nécessaire de s'y appesantir. With reference to FIG. 1, the double connection device according to the invention is consists, in the upper part, of a traditional cage mechanism (1) and screws (2) to which is added a quick connection system spring blade shaped loop (3). The direction and direction of insertion of drivers on the one hand, and teeth of the connecting rods on the other hand, are indicated respectively by arrows A and B. The operation of the cage connector (1) and screw (2) being classic, it is not necessary to dwell on it.

Au niveau de son ouverture (4), la boucle (3) présente des tronçons d'extrémité formant un léger évasement, qui permet l'introduction d'une dent de barre de pontage dans de bonnes conditions. A l'opposé de l'ouverture (4), la lame ressort (3) en forme de boucle comporte une borne (5) de liaison avec le noyau fonctionnel d'un appareil modulaire électrique comprenant le dispositif à double connexion de l'invention. La cage (1) est tronquée en partie basse pour permettre l'intégration des tronçons d'extrémité évasés de la boucle dans le boítier.At its opening (4), the loop (3) has sections end forming a slight flare, which allows the introduction of a tooth of bridging bar in good conditions. In contrast to the opening (4), the spring blade (3) has a connection terminal (5) with the functional core of an electrical modular apparatus comprising the dual connection of the invention. The cage (1) is truncated at the bottom for allow integration of the flared end sections of the loop in the housing.

L'intégration dans un boítier est d'ailleurs montrée en figure 2. L'appareil est un disjoncteur, et la borne (5) est alors reliée à la bobine (6) d'un sous-ensemble magnétique. On peut noter la proximité du ou des conducteurs (7) insérés dans la cage (1) et des dents (8) de la barre de pontage (9), en position d'enfichage dans la lame ressort (3). Cette proximité s'explique par les contraintes à respecter, et comporte des avantages sur le plan électrique. Pour mémoire, il n'est pas possible de disposer la lame ressort (3) plus proche de la semelle, pour respecter le niveau de pontage. Il n'est pas non plus envisageable de remonter la cage (1) car, pour des raisons de sécurité, la tête de vis (2) doit être située à une certaine distance de la façade (F) du boítier (B). Les normes prévoient en effet que les utilisateurs ne puissent pas avoir accès à des parties sous tension. Enfin, à cause du plastron qui est installé dans les coffrets, il ne saurait être question non plus de modifier le profil du boítier (B), et notamment de déplacer la façade (F).The integration into a housing is also shown in Figure 2. The device is a circuit breaker, and the terminal (5) is then connected to the coil (6) of a subassembly magnetic. It can be noted the proximity of the conductor (s) (7) inserted in the cage (1) and teeth (8) of the bridging bar (9), in the insertion position in the spring blade (3). This proximity is explained by the constraints to be respected, and has electrical advantages. For the record, it is not possible to arrange the spring blade (3) closer to the sole, to respect the level bridging. It is also not possible to reassemble the cage (1) because, for for safety reasons, the screw head (2) must be located at a distance of the facade (F) of the housing (B). The standards stipulate that users should not may not have access to live parts. Finally, because of the plastron is installed in the boxes, there can be no question of changing the profile housing (B), including moving the front (F).

C'est la raison pour laquelle cette superposition de deux moyens de connexion différents, la cage (1) et vis (2) d'une part, et la lame ressort (3) d'autre part, doivent être disposés aussi près l'un de l'autre.This is the reason why this superposition of two means of connection different, the cage (1) and screw (2) on the one hand, and the spring blade (3) on the other, must be arranged so close to each other.

Dans la configuration des figures 1 et 2, la lame ressort (3) est, bien entendu, conductrice. Ce n'est pas le cas dans la configuration de la figure 3 dans laquelle la lame ressort (13) a une fonction purement mécanique, plaquer la dent (8) de la barre de pontage (9) (insérée dans la direction de la flèche B) au contact de la paroi inférieure (10) de la cage (1). La transmission du courant électrique se fait alors par l'intermédiaire de ladite paroi (10). Le support sur lequel est fixée la lame ressort (13) est constitué d'une paroi (12) réalisant, avec le prolongement (11) d'une des parois latérales de la cage (1), une extension en L de cette dernière. Il s'agit en fait d'une configuration à double cages, la cage inférieure formée des parois (11, 12) n'étant pas nécessairement complétée par une paroi latérale faisant face au côté (11 ).In the configuration of FIGS. 1 and 2, the leaf spring (3) is, of course, conductive. This is not the case in the configuration of Figure 3 in which the spring blade (13) has a purely mechanical function, to press the tooth (8) of the bridging bar (9) (inserted in the direction of arrow B) in contact with the wall lower (10) of the cage (1). The transmission of the electric current is then done by via said wall (10). The support on which the spring blade is fixed (13) consists of a wall (12) forming, with the extension (11) of one of side walls of the cage (1), an extension L of the latter. This is actually of a double cage configuration, the lower cage formed by the walls (11, 12) not necessarily complemented by a sidewall facing the side (11).

La description ci-dessus ne concerne que deux exemples qui ne peuvent pas être considérés comme exhaustifs de l'invention. Celle-ci englobe au contraire toutes les variantes de forme et de configuration qui sont à la portée de l'homme de l'art.The description above only concerns two examples that can not be be considered as exhaustive of the invention. On the contrary, it encompasses all the variants of form and configuration that are within the grasp of the man of art.
