Description

La présente invention concerne d'une manière générale les appareils électriques propres à être rapportés par encliquetage sur un quelconque rail de montage, comme cela est le cas, par exemple, au sein des armoires, dites armoires électriques, dans lesquelles peuvent être regroupés un certain nombre de tels appareils.The present invention relates in a way general clean electrical appliances to be reported by snap-fastening on any rail mounting, as is the case, for example, within cabinets, called electrical cabinets, in which a certain group can be grouped number of such devices.

De tels appareils électriques sont communément appelés "modulaires", dans la mesure où, tous de même profil transversal, ils ont chacun une longueur qui est un multiple d'un même module de base commun à l'ensemble.Such electrical devices are commonly called "modular", since, all with the same transverse profile, they each have a length which is a multiple of the same module of basis common to the whole.

Disposés les uns à la suite des autres sur un même rail de montage, il peut être nécessaire d'établir de l'un à l'autre des liaisons électriques.Arranged one after the other on a same mounting rail, it may be necessary to establish electrical connections from one to the other.

C'est le cas, par exemple, pour les appareils électriques destinés à l'équipement d'une installation au sein de laquelle il y a à surveiller l'état d'ouverture ou de fermeture de divers contacts disséminés en divers points, et, le cas échéant, à déclencher en conséquence une alarme.This is the case, for example, for devices electrical equipment for installation within which there is to monitor the state opening or closing of various contacts disseminated at various points, and, where appropriate, at trigger an alarm accordingly.

Deux appareils électriques distincts, au moins, sont en effet alors à mettre en euvre, l'un destiné à la seule alimentation de l'ensemble, l'autre propre, d'une part, à la desserte d'un certain nombre de boucles de surveillance, et, d'autre part, à la gestion de celles-ci, étant entendu que, en fonction de la puissance dont est capable le premier, il est possible que soit adjoint à ce deuxième appareil un troisième, qui, ne constituant qu'une simple extension du précédent, n'est propre, lui, qu'à la desserte d'un certain nombre de boucles de surveillance supplémentaires.At least two separate electrical devices, are in fact then to be implemented, one intended for the only supply of the whole, the other clean, on the one hand, serving a number of monitoring loops, and, secondly, to management of these, it being understood that, depending on the power of which the first is capable it is may be added to this second device a third, which, constituting only a simple extension of the above, is only suitable for serving a number of monitoring loops additional.

A ce jour, lorsque des liaisons électriques sont à établir entre des appareils électriques ainsi échelonnés le long d'un même rail de montage, ces liaisons électriques se font usuellement à l'aide de pontages réalisés chacun par un fil.To date, when electrical connections are to be established between electrical devices so staggered along the same mounting rail, these electrical connections are usually made using bypasses each made by a wire.

Une telle disposition présente divers inconvénients.Such an arrangement has various drawbacks.

Tout d'abord, dans la liaison électrique à établir entre un composant d'un appareil et un composant de l'autre, elle conduit à une multiplication des points de contact.First, in the electrical connection to be established between a component of a device and a component on the other, it leads to a multiplication of contact points.

En effet, alors même que de tels composants sont usuellement directement rapportés sur une "carte", c'est-à-dire sur une plaquette de support également porteuse d'un circuit imprimé propre à leur desserte, ce qui implique pour chacun de ces constituants un premier point de contact, il est nécessaire, pour le branchement du fil assurant la liaison électrique concernée, de mettre en oeuvre, sur cette même carte, une borne de connexion, par exemple une borne de connexion à vis, propre au branchement de ce fil, ce qui implique, en sus, un deuxième point de contact entre une telle borne de connexion et la carte concernée et un troisième point de contact entre le fil et cette borne de connexion, soit, pour l'ensemble de la liaison électrique ainsi réalisée, un total de six points de contact.Indeed, even as such components are usually reported directly on a "card", that is to say on a support plate also carrying a printed circuit specific to their service, which implies for each of these constituents a first point of contact it's necessary, for the connection of the wire ensuring the electrical connection concerned, to implement, on this same card, a connection terminal, by example a screw connection terminal, specific to the connection of this wire, which implies, in addition, a second point of contact between such a terminal connection and the card concerned and a third point of contact between the wire and this terminal connection, that is, for the entire electrical connection thus achieved, a total of six points of contact.

Il en résulte inévitablement une résistance de passage relativement élevée pouvant entraíner une chute de tension nuisible, notamment lorsque, comme cela est le cas en électronique, les courants correspondants sont des courants faibles.This inevitably results in resistance from relatively high passage which can lead to harmful voltage drop, especially when, as is the case in electronics, the currents corresponding are weak currents.

De plus, les liaisons électriques ainsi réalisées sont malaisées à exécuter, longues et coûteuses, notamment lorsque l'accessibilité aux appareils électriques concernés est mesurée, comme cela est précisement le cas par exemple lorsque ces appareils électriques sont installés au fond d'une armoire électrique, et leur bonne exécution dépend de l'opérateur qui en assure la réalisation.In addition, the electrical connections thus made are difficult to execute, long and expensive, especially when accessibility to devices affected electrical is measured, like this is precisely the case for example when these electrical appliances are installed at the bottom of a electrical cabinet, and their proper execution depends of the operator who ensures its realization.

Enfin, malgré le repérage usuellement prévu pour obvier à cette difficulté, des erreurs de branchement sont toujours possibles, notamment lorsque, pour un dépannage, il faut débrancher un appareil pour lui en substituer un autre.Finally, despite the usually planned location to avoid this difficulty, connection errors are always possible, especially when, for troubleshooting, you must unplug a device to replace it with another.

La présente invention a d'une manière générale pour objet une disposition permettant d'éviter ces inconvénients.The present invention generally subject to a provision to avoid these disadvantages.

De manière plus précise, elle a tout d'abord pour objet un connecteur de liaison pour appareil électrique à mise en place par encliquetage sur un rail de montage, ce connecteur de liaison ledit connecteur de liaison comportant une embase en matière isolante, qui est propre à se loger sous les boítiers de deux appareils électriques successifs, entre de tels boítiers et le rail de montage sous-jacent, en étant engagé pour partie dans un évidement prévu à cet effet dans le boítier d'un desdits appareils électriques et pour partie dans un évidement également prévu à cet effet dans le boítier de l'autre de ceux-ci, et, porté par ladite embase, au moins un organe de connexion métallique, qui, à chacune des extrémités transversales de cette embase, présente une pièce de contact propre à une liaison électrique avec une piste de contact prévue à cet effet dans l'évidement du boítier de l'appareil électrique correspondant ; elle a encore pour objet un appareil électrique à mise en place par encliquetage sur un rail de montage spécialement adapté à la mise en oeuvre d'un tel connecteur de liaison.More specifically, it has first for a device connector connector electric snap-in installation on a mounting rail, this connecting connector said connector of connection comprising a base in insulating material, which is suitable for being housed under the housings of two successive electrical appliances, between such boxes and the underlying mounting rail, by being partly engaged in a recess provided for this purpose in the housing of one of said electrical appliances and partly in a recess also provided for this purpose in the housing the other of these, and, carried by said base, at minus a metallic connection member, which each of the transverse ends of this base, presents a contact part specific to a electrical connection with a planned contact track for this purpose in the recess of the housing of the device corresponding electric; it still has for object an electrical appliance with snap-in installation on a specially adapted mounting rail to the implementation of such a connector liaison.

En pratique, le connecteur de liaison suivant l'invention comporte, parallèlement les uns aux autres, plusieurs organes de connexion, qui sont tous identiques entre eux, et dont les pièces de contact sont élastiquement déformables sensiblement perpendiculairement à l'embase qui les porte, pour leur application sous pression élastique avec les pistes de contact correspondantes de l'appareil électrique concerné. In practice, the following link connector the invention comprises, parallel to each other, several connecting members, which are all identical to each other, and whose contact parts are elastically deformable substantially perpendicularly to the base that carries them, for their application under elastic pressure with corresponding device contact tracks electric concerned.

Par exemple, dans une forme préférentielle de réalisation, ces organes de connexion se présentent sous la forme de simples épingles métalliques en fil rond convenablement conformé.For example, in a preferred form of realization, these connecting members are presented in the form of simple metal pins in suitably shaped round wire.

Quoi qu'il en soit, pour la mise en oeuvre d'un tel connecteur de liaison, un appareil électrique suivant l'invention comporte, conjointement, à l'une au moins des extrémités transversales de son boítier, à la base de celle-ci, un évidement, dans lequel peut s'engager un tel connecteur de liaison, et dans lequel débouche au moins une piste de contact, et, en pratique, une pluralité de telles pistes de contact, à raison d'une par organe de connexion porté par ledit connecteur de liaison.Anyway, for the implementation of a such a connector, an electrical appliance according to the invention comprises, jointly, with one at least transverse ends of its housing, at the base of it, a recess, in which can engage such a connection connector, and into which at least one track leads contact, and, in practice, a plurality of such contact leads, one for each connection carried by said link connector.

Par exemple, lorsque un tel appareil électrique comporte, pour le support et/ou la desserte d'un ou plusieurs constituants, une plaquette de circuit imprimé, ou "carte", ces pistes de contact peuvent très simplement être portées par cette plaquette de circuit imprimé, et c'est donc celle-ci qui débouche directement dans l'évidement correspondant de son boítier.For example, when such an electrical appliance includes, for the support and / or the service of one or several components, a printed circuit board, or "card", these contact leads can very simply be carried by this plate of printed circuit, and it is therefore this which leads directly in the corresponding recess of its case.

Quoi qu'il en soit, pour les liaisons électriques à établir entre deux appareils électriques à mise en place par encliquetage sur un rail de montage, il suffit, grâce au connecteur de liaison suivant l'invention, d'encliqueter l'un de ces appareils électriques sur ce rail de montage, de glisser un tel connecteur de liaison sous le boítier de cet appareil électrique, puis d'encliqueter à son tour sur le rail de montage le deuxième appareil électrique concerné, soit, directement, sur le connecteur de liaison, soit à distance de celui-ci, son encliquetage sur le rail de montage étant alors suivi d'un coulissement le long de ce dernier jusqu'à engagement de son boítier sur ledit connecteur de liaison.Anyway, for electrical connections to be set up between two electrical appliances snap-in place on a mounting rail, it sufficient, thanks to the connection connector according to the invention, to snap one of these electrical devices on this mounting rail, to slide such connection connector under the housing of this unit electric, then click in turn on the mounting rail the second electrical appliance concerned, either directly on the connector of connection, or at a distance from it, its snap-fastening on the mounting rail then being followed by sliding along the latter until engagement from its housing on said connection connector.

Le montage, ainsi simplifié, est très aisé et rapide, et il ne nécessite aucune habilité particulière ni aucun outil spécifique.The assembly, thus simplified, is very easy and fast, and requires no special skills nor any specific tool.

Il peut s'appliquer aussi bien à l'installation initiale des appareils électriques concernés qu'à toute autre intervention ultérieure sur ceux-ci, telle que celles nécessaires par exemple pour leur maintenance ou leur remplacement.It can apply as well to installation initial of the electrical devices concerned only any other subsequent intervention on them, such as than those needed for example for their maintenance or replacement.

Dans tous les cas, des dispositions de forme complémentaires, formant détrompeur, étant prévues à cet effet entre le connecteur de liaison et les appareils électriques susceptibles d'être concernés, il n'y a aucun risque de mauvais branchement entre ces appareils électriques.In all cases, formal provisions complementary, forming a key, being provided for this purpose between the link connector and electrical appliances likely to be concerned, there is no risk of improper connection between these electrical devices.

En outre, le nombre de points de contact intervenant dans la liaison électrique établie entre un constituant d'un des deux appareils électriques concernés et un constituant de l'autre de ceux-ci se trouve avantageusement réduit à quatre, aucune borne de connexion, à vis ou autre, n'intervenant dans une telle liaison électrique, ce qui réduit avantageusement la résistance de passage de l'ensemble.In addition, the number of contact points involved in the electrical connection established between a component of one of the two electrical devices concerned and a constituent of the other of these is advantageously reduced to four, none connection terminal, screw or other, not involved in such an electrical connection, which advantageously reduces the passage resistance of the assembly.

Enfin, recouvertes par le boítier même des appareils électriques concernés, les liaisons électriques ainsi assurées entre ces appareils électriques sont avantageusement inaccessibles en fonctionnement normal, ce qui, notamment, les met avantageusement à l'abri de toute intervention fortuite intempestive, et, donc, constitue une garantie pour leur pérennité.Finally, covered by the case itself affected electrical devices, electrical connections thus ensured between these electrical devices are advantageously inaccessible in operation normal, which, in particular, puts them advantageously safe from any chance intervention untimely, and therefore constitutes a guarantee for their sustainability.

    • Tel qu'il est visible sur ces figures, et, plus particulièrement, sur les figures 1 et 2, il s'agit d'assurer une ou plusieurs liaisons électriques entre deux appareils électriques 10, en l'espèce des appareils électriques 10A et 10B, du type à mise en place par encliquetage sur un rail de montage 11, étant entendu que, ainsi qu'il apparaítra ultérieurement, un nombre supérieur de tels appareils électriques 10 peut être concerné.As it can be seen in these figures, and, more in particular, in FIGS. 1 and 2, it is ensure one or more electrical connections between two electrical devices 10, in this case electric appliances 10A and 10B, of the bet type in place by snapping onto a mounting rail 11, it being understood that, as will appear later, more such devices electrical 10 may be affected.

    Ces appareils électriques 10 étant connus par eux-mêmes, et ne relevant pas de la présente invention, ils ne seront pas décrit dans tous leurs détails ici.These electrical devices 10 being known by themselves, and not covered by this invention they will not be described in all their details here.

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

    Il suffira, pour ce faire, d'indiquer qu'ils comportent, chacun, dans un boítier 12 propre à coiffer le rail de montage 11 en s'agrippant de manière démontable à celui-ci, un ou plusieurs constituants à relier électriquement à un ou plusieurs constituants de l'autre.To do this, it will suffice to indicate that they include, each, in a box 12 suitable for styling the mounting rail 11 by gripping so removable therefrom, one or more constituents to be electrically connected to one or more components the other.

    En pratique, le boítier 12 a un même contour transversal pour l'un et l'autre des appareils électriques 10 concernés, et sa longueur, éventuellement différente de l'un à l'autre de ceux-ci, est un multiple d'un module de base commun à tous.In practice, the housing 12 has the same outline transverse for both electrical devices 10 concerned, and its length, if necessary different from one to another of these, is a multiple a basic module common to all.

    La forme de réalisation représentée illustre plus particulièrement, à titre d'exemple, le cas où, comme il est usuel, chacun des appareils électriques 10 concernés comporte, dans son boítier 12, pour le support et/ou la desserte de ses constituants, une "carte" 13, c'est-à-dire une plaquette de circuit imprimé.The embodiment shown illustrates more particularly, for example, the case where, as it is usual, each of the electrical appliances 10 concerned has, in its housing 12, for the support and / or the service of its constituents, a "card" 13, that is to say a circuit board printed.

    Le rail de montage 11 n'est pas lui non plus concerné par la présente invention.The mounting rail 11 is not either concerned with the present invention.

    Dans la forme de réalisation représentée, il s'agit d'un rail symétrique, c'est-à-dire d'un rail dont les ailes, de même hauteur, sont chacune munies d'un retour en équerre le long de leur bord, en directions opposées l'une par rapport à l'autre.In the embodiment shown, it it is a symmetrical rail, i.e. a rail whose wings, of the same height, are each provided with a square return along their edge, in opposite directions to each other.

    Mais il pourrait aussi bien s'agir d'un rail dissymétrique, c'est-à-dire d'un rail dont les ailes, de hauteurs différentes, ont leur retour en équerre dirigé l'une vers l'autre.But it could also be an asymmetrical rail, that is to say of a rail whose wings, of different heights, have their back square directed towards each other.

    Suivant l'invention, pour les liaisons électriques à établir entre les appareils électriques 10 concernés, en l'espèce entre les appareils électriques 10A et 10B, qui sont de types différents, il est mis en oeuvre un connecteur de liaison 15 comportant, d'une part, une embase en matière isolante 16, qui est propre à se loger, à la manière d'un tiroir, sous les boítiers 12 de ces deux appareils électriques 10A, 10B successifs, entre de tels boítiers 12 et le rail montage 11 sous-jacent, en étant engagé pour partie dans un évidement 17A prévu à cet effet dans le boítier 12 de l'appareil électrique 10A et pour partie dans un évidement 17B également prévu à cet effet dans le boítier 12 de l'appareil électrique 10B, et, d'autre part, porté par ladite embase 16, au moins un organe de connexion métallique 20, qui, à chacune des extrémités transversales de cette embase 16, présente une pièce de contact 21, propre à une liaison électrique avec une piste de contact 22 prévue à cet effet dans l'évidement 17A, 17B du boítier 12 de l'appareil électrique 10A, 10B correspondant.According to the invention, for electrical connections to be established between the electrical devices 10 concerned, in this case between electrical appliances 10A and 10B, which are of different types, it is put using a connection connector 15 comprising, on the one hand, a base made of insulating material 16, which is suitable to be housed, like a drawer, under the boxes 12 of these two electrical devices 10A, 10B successive, between such boxes 12 and the underlying mounting rail 11, being engaged for part in a recess 17A provided for this purpose in the housing 12 of the electrical appliance 10A and partly in a recess 17B also provided for this purpose in the housing 12 of the device electric 10B, and, on the other hand, carried by said base 16, at least one connection member metallic 20, which at each of the transverse ends of this base 16, has a part contact 21, suitable for an electrical connection with a contact track 22 provided for this purpose in the recess 17A, 17B of the housing 12 of the apparatus electric 10A, 10B corresponding.

    En pratique, le connecteur de liaison 15 comporte, parallèlement les uns aux autres, plusieurs organes de connexion 20 identiques.In practice, the connection connector 15 comprises, parallel to each other, several identical connecting members 20.

    Par exemple, dans la forme de réalisation représentée sur les figures 3, 4, il y a ainsi trois organes de connexion 20.For example, in the embodiment shown in figures 3, 4, there are thus three connecting members 20.

    Chacun d'eux est constitué d'une épingle en fil rond, figure 8, et il comporte, d'un seul tenant, une partie médiane 23, par laquelle, tel que décrit ultérieurement, il est assujetti à l'embase 16 qui porte l'ensemble, et, disposées chacune respectivement aux extrémités de cette partie médiane 23, deux ailes qui en forment les pièces de contact 21.Each of them consists of a wire pin round, figure 8, and it comprises, in one piece, a middle part 23, through which, as described later, it is subject to the base 16 which carries the set, and, each arranged respectively at the ends of this middle part 23, two wings which form the contact parts 21.

    Par exemple, et tel que représenté, ces ailes forment chacune un angle aigu V, de l'ordre de 30°, avec la partie médiane 23 qu'elles encadrent.For example, and as shown, these wings each form an acute angle V, of the order of 30 °, with the middle part 23 which they frame.

    Dans la forme de réalisation représentée, ces ailes, qui se raccordent chacune par un large congé arrondi à la partie médiane 23, se prolongent chacune, à leur extrémité libre, au-delà d'un congé également largement arrondi, par un retour 24 parallèle à elles-mêmes.In the embodiment shown, these wings, each connected by a wide leave rounded off to middle part 23, extend each, at their free end, beyond one leave also largely rounded off, by a return 24 parallel to themselves.

    Quoi qu'il en soit, chacune des pièces de contact 21 que présente ainsi un organe de connexion 20 est élastiquement déformable sensiblement perpendiculairement à l'embase 16 portant l'ensemble.Either way, each of the pieces of contact 21 thus presented by a connection 20 is elastically deformable substantially perpendicular to the base 16 carrying all.

    Les organes de connexion 20 que comporte ainsi le connecteur de liaison 15 suivant l'invention sont chacun individuellement logés dans des évidements 25 de son embase 16, qui, allongés en forme de fente, parallèlement les uns aux autres, à distance les uns des autres, débouchent tous à la surface de cette embase 16, et seules les pièces de contact 21 que forment, comme décrit précédemment, à leurs extrémités, ces organes de connexion 20, émergent de ces évidements 25.The connection members 20 that comprises thus the connector 15 according to the invention are each individually housed in recesses 25 of its base 16, which, elongated in slot shape, parallel to each other, to distance from each other, all lead to the surface of this base 16, and only the parts contact 21 formed, as described above, at their ends, these organs of connection 20, emerge from these recesses 25.

    Dans la forme de réalisation représentée, l'embase 16, de contour globalement parallélépipédique, compte non tenu d'un usuel angle de dépouille, comporte une platine 26, dans laquelle sont ménagés les évidements 25 précédents, et, à la périphérie de cette platine 26, pour appui sur le rail de montage 11, une jupe 27.In the embodiment shown, the base 16, of generally parallelepipedic outline, not taking into account a usual draft angle, comprises a plate 26, in which are made the previous recesses 25, and, at the periphery of this plate 26, for support on the rail mounting 11, a skirt 27.

    En pratique, dans cette forme de réalisation, sur deux des côtés opposés de la platine 26, qui, par rapport au sens d'allongement du rail de montage 11, forment les côtés transversaux de cette platine 26, la jupe 27 est largement échancrée. In practice, in this embodiment, on two of the opposite sides of the plate 26, which, relative to the direction of elongation of the mounting rail 11, form the transverse sides of this platinum 26, the skirt 27 is largely indented.

    Les évidements 25 s'étendent parallèlement aux deux autres côtés de la platine 26, et, donc, parallèlement aux côtés longitudinaux de celle-ci.The recesses 25 extend in parallel at the other two sides of the plate 26, and, therefore, parallel to the longitudinal sides thereof.

    Dans la forme de réalisation représentée, ils sont au nombre de huit.In the embodiment shown, they are eight in number.

    A chacun de certains au moins de ces évidements 25, il est associé, sur l'embase 16, un repère 29.To each of at least some of these recesses 25, there is associated, on the base 16, a reference 29.

    Il s'agit, dans la forme de réalisation représentée, de bossages globalement hémisphériques en saillie sur une facette 30 de la platine 26, qui, disposée le long d'un des côtés transversaux de cette platine 26, est légèrement en retrait par rapport à sa surface supérieure.This is, in the embodiment shown, globally hemispherical bosses in protrusion on a facet 30 of the plate 26, which, arranged along one of the transverse sides of this plate 26, is slightly behind relative on its upper surface.

    En pratique, dans la forme de réalisation représentée, il est ainsi associé un repère 29 à trois des évidements 25, ceux effectivement concernés par les trois organes de connexion 20 mis en oeuvre dans cette forme de réalisation.In practice, in the embodiment shown, a reference 29 is thus associated with three of the recesses 25, those actually affected by the three connection members 20 used in this embodiment.

    Quoi qu'il en soit, chacun des évidements 25 que comporte l'embase 16 présente, transversalement, et symétriquement de part et d'autre de sa direction d'allongement, trois épanouissements, à savoir un épanouissement 32 dans sa zone médiane, et deux épanouissements 33 disposés, chacun respectivement, à ses extrémités.Anyway, each of the recesses 25 that comprises the base 16 present, transversely, and symmetrically on either side of its direction of lengthening, three bloomings, know a blooming 32 in its middle zone, and two openings 33 arranged, each respectively, at its ends.

    Les poinçons à mettre en oeuvre pour la formation de ces évidements 25 lors du moulage de l'ensemble se trouvent ainsi avantageusement renforcés.Punches to be used for training of these recesses 25 during the molding of the assembly is thus advantageously reinforced.

    Dans la forme de réalisation représentée, chacun des organes de connexion 20 mis en oeuvre est encliqueté, par sa partie médiane 23, sous un crochet 35 présent à cet effet au fond de l'évidement 25 dans lequel il est logé, à la faveur de l'épanouissement 32 correspondant de cet évidement 25.In the embodiment shown, each connection members 20 used is snapped, by its middle part 23, under a hook 35 present for this purpose at the bottom of the recess 25 in which he is housed, thanks to the corresponding development 32 of this recess 25.

    D'un évidement 25 à l'autre, les crochets 35 sont disposés dos à dos, et ils présentent chacun une facette oblique d'engagement 36, dirigée vers l'intérieur de l'évidement 25 correspondant, et une facette de retenue 37, qui, parallèle au fond de cet évidement 35, s'étend à une distance de celui-ci sensiblement égale au diamètre du fil rond dont sont constitués les organes de connexion 20.From one recess 25 to another, the hooks 35 are arranged back to back, and they each present an oblique facet of engagement 36, directed towards the interior of the corresponding recess 25, and a retaining facet 37, which, parallel to the bottom of this recess 35, extends at a distance therefrom substantially equal to the diameter of the round wire of which the connection members 20 are made up.

    En pratique, pour chaque évidement 25, le crochet 35 s'étend transversalement au-delà de la ligne médiane d'un tel évidement 25.In practice, for each recess 25, the hook 35 extends transversely beyond the center line of such a recess 25.

    Ainsi qu'il est aisé de le comprendre, l'épanouissement 32 à la faveur duquel s'étend ainsi un tel crochet 35 facilite en outre la mise en place d'un organe de connexion 20 dans un tel évidement 25, cette mise en place impliquant une déformation élastique temporaire de la partie médiane 23 d'un tel organe de connexion 20, jusqu'à son engagement local sous ce crochet 35.As it is easy to understand, the flourishing 32 in favor of which thus extends a such hook 35 further facilitates the establishment a connection member 20 in such a recess 25, this installation involving a deformation temporary elastic of the middle part 23 of such a connecting member 20, until its local engagement under this hook 35.

    Pour le reste, c'est-à-dire dans leur partie courante, entre leurs épanouissements 32, 33, les évidements 25 ont une largeur à peine supérieure au diamètre du fil rond dont sont constitués les organes de connexion 20, pour un bon maintien de ceux-ci.For the rest, that is to say in their current part, between their blossoms 32, 33, the recesses 25 have a width barely greater than the diameter of the round wire of which the organs are made connection 20, for good maintenance of these.

    Dans la forme de réalisation représentée, l'embase 16 du connecteur de liaison 15 suivant l'invention présente, latéralement en saillie, le long de l'un au moins de ses côtes longitudinaux, une languette 39.In the embodiment shown, the base 16 of the connector 15 according to the invention present, laterally projecting, along at least one of its longitudinal ribs, a tab 39.

    En pratique, dans cette forme de réalisation, une telle languette 39 n'est prévue que le long de l'un des côtés longitudinaux de l'embase 16, à la base de celle-ci.In practice, in this embodiment, such a tongue 39 is only provided along one of the longitudinal sides of the base 16, at the basis of it.

    En outre, dans cette forme de réalisation, cette languette 39 comporte deux tronçons successifs 39A, 39B de hauteurs HA, HB différentes, en formant, dans sa zone médiane, une marche 40.Furthermore, in this embodiment, this tongue 39 has two successive sections 39A, 39B of different heights HA, HB, forming, in its middle zone, a step 40.

    En pratique, ces tronçons 39A, 398 s'étendent sensiblement chacun à mi-longueur par rapport à l'embase 16, et celui, 39A, qui est disposé du côté de l'appareil électrique 10A, a une hauteur moyenne HA inférieure à la hauteur moyenne HB de celui, 39B, situé du côté de l'appareil électrique 10B.In practice, these sections 39A, 398 extend substantially each at mid-length compared to the base 16, and that, 39A, which is arranged on the side of the 10A electrical appliance, at an average height HA less than the average height HB of the one, 39B, located on the side of the electrical appliance 10B.

    Enfin, pour son guidage le long du rail de montage 11, l'embase 16 du connecteur de liaison 15 suivant l'invention présente, en saillie sur sa surface inférieure, dans la forme de réalisation représentée, le long de l'un au moins de ses côtés longitudinaux, au moins un ergot 42.Finally, for its guidance along the rail of mounting 11, the base 16 of the connection connector 15 according to the present invention, projecting from its lower surface, in the embodiment shown, along at least one of its sides longitudinal, at least one lug 42.

    En pratique, dans cette forme de réalisation, deux ergots 42 sont ainsi prévus, à distance l'un de l'autre, le long d'un seul des côtés longitudinaux de l'embase 16, celui le long duquel est déjà présente la languette 39.In practice, in this embodiment, two pins 42 are thus provided, one at a distance on the other, along only one of the longitudinal sides of the base 16, the one along which is already presents tab 39.

    Corollairement, l'évidement 17A que présente le boítier 12 de l'appareil électrique 10A pour l'engagement du connecteur de liaison 15 suivant l'invention a un contour transversal dont une partie au moins est au profil de l'embase 16 de ce connecteur de liaison 15, et, en particulier, ce contour transversal présente, latéralement, en correspondance avec la languette 39 de ce connecteur de liaison 15, un décrochement 41 dont la hauteur H'A, compte tenu de l'emprise du boítier 12 sur le rail de montage 11, correspond à la hauteur HA du tronçon de moindre hauteur 39A de cette languette 39, tout en étant légèrement supérieure à celle-ci.As a corollary, the recess 17A that presents the housing 12 of the electrical appliance 10A for engagement of the connector 15 according to the invention has a transverse contour, part of which at the minus is the profile of the base 16 of this connector link 15, and, in particular, this contour transverse present, laterally, in correspondence with tab 39 of this connector link 15, a recess 41 whose height H'A, given the grip of the housing 12 on the mounting rail 11, corresponds to the height HA of the lower section 39A of this tongue 39, while being slightly higher than this.

    En pratique, le boítier de l'appareil électrique 10A ne comporte ainsi un évidement 17A qu'à l'une de ses extrémités transversales, celle concernée par le connecteur de liaison 15, à la base de cette extrémité transversale.In practice, the housing of the electrical appliance 10A thus includes a recess 17A only one of its transverse ends, that concerned by the connector 15, at the base of this transverse end.

    Par contre, et pour des raisons qui apparaítront ci-après, le boítier 12 de l'appareil électrique 10B présente un évidement à l'une et l'autre de ses extrémités transversales.On the other hand, and for reasons that will appear below, the housing 12 of the electrical appliance 10B presents a recess to both of its transverse ends.

    Ainsi, outre l'évidement 17B qu'il présente à son extrémité transversale concernée par le connecteur de liaison 15, il présente un évidement 17'B à son extrémité transversale opposée, figures 1 et 11.Thus, in addition to the recess 17B which it presents to its transverse end concerned by the connection connector 15, it has a recess 17'B at its opposite transverse end, figures 1 and 11.

    Comme précédemment, le contour transversal de ces évidements 17B, 17'B est au moins pour partie au profil de l'embase 16 du connecteur de liaison 15, et, notamment, il présente, latéralement, en correspondance avec la languette 39 de ce connecteur de liaison 15, un décrochement 42', 42" dont la hauteur H'B correspond, dans les mêmes conditions que précédemment, à la hauteur HB du tronçon de plus grande hauteur 39B de cette languette 39.As before, the transverse contour of these recesses 17B, 17'B is at least for part of the profile of the base 16 of the connector link 15, and, in particular, it has, laterally, in correspondence with tab 39 of this connection connector 15, a recess 42 ', 42 " whose height H'B corresponds, in the same conditions as before, at the height of HB of longer section 39B of this tongue 39.

    Ainsi, suivant l'appareil électrique 10A ou 10B concerné, la hauteur H'A, H'B du décrochement latéral 41, 42', 42" de l'évidement 17A, 17B ou 17'B d'un tel appareil électrique correspond à l'une ou à l'autre des hauteurs HA, HB de la languette 39 de l'embase 16 du connecteur de liaison 15.Thus, depending on the electrical appliance 10A or 10B concerned, the height H'A, H'B of the offset lateral 41, 42 ', 42 "of the recess 17A, 17B or 17'B of such an electrical appliance corresponds to one or the other of the heights HA, HB of the tongue 39 of the base 16 of the connection connector 15.

    Cette languette 30 constitue, donc, dans la forme de réalisation représentée, et ainsi qu'il apparaítra mieux ultérieurement, un détrompeur.This tongue 30 therefore constitutes, in the embodiment shown, and as it will appear better later, a key.

    Quoi qu'il en soit, les pistes de contact 22 dont sont dotés les appareils électriques 10A, 10B sont en pratique présentes à la surface inférieures de leur carte ou plaquette de circuit imprimé 13, celle-ci s'étendant largement à cet effet dans l'évidement 17A, 17B ou 17'B correspondant, à la partie haute de celui-ci.Anyway, contact leads 22 including are equipped with electrical devices 10A, 10B are in practice present at the lower surface of their printed circuit board or card 13, this one extending widely for this purpose in the recess 17A, 17B or 17'B corresponding to the part high of it.

    De préférence, et tel que représenté, il est prévu, tranversalement, dans un tel évidement 17A, 17B ou 17'B, une butée 44 propre à y limiter l'engagement d'un connecteur de liaison 15.Preferably, and as shown, it is provided, transversely, in such a recess 17A, 17B or 17'B, a stop 44 suitable for limiting it engagement of a link connector 15.

    Il s'agit, en pratique, d'une cloison interne du boítier 12 concerné.In practice, this is an internal partition of the case 12 concerned.

    Pour la mise en oeuvre du connecteur de liaison 15 suivant l'invention, il est procédé, d'abord, de manière usuelle, à la mise en place, par encliquetage, de l'appareil électrique 10A sur le rail de montage 11, figure 13A.For the implementation of the connection connector 15 According to the invention, first of all, in the usual way, during installation, by snap-fastening, of the 10A electrical appliance on the rail assembly 11, figure 13A.

    L'organe de liaison 15 est alors à son tour appliqué, par la tranche de sa jupe 27, contre se rail de montage 11, avec contact de ses ergots 42 avec la tranche de l'aile correspondante de celui-ci.The link member 15 is then in turn applied, by the edge of her skirt 27, against mounting rail 11, with contact of its lugs 42 with the edge of the corresponding wing of it.

    Il suffit, ensuite, de faire coulisser le connecteur de liaison 15 le long du rail de montage 11, suivant la flèche F1 de la figure 13A, jusqu'à ce qu'il s'engage pour moitié dans l'évidement 17A correspondant du boítier 12 de l'appareil électrique 10A, figure 13B.Then simply slide the connector connecting 15 along the mounting rail 11, along arrow F1 in Figure 13A, until that it engages for half in the recess 17A correspondent of the box 12 of the electrical appliance 10A, Figure 13B.

    Compte tenu des dispositions décrites précédemment, cet engagement ne peut se faire que suivant une orientation bien déterminée, pour laquelle la languette 39 du connecteur de liaison 15 est du même côté que le décrochement 41 de l'évidement 17A du boítier 12 de l'appareil électrique 10A, avec son tronçon de moindre hauteur 39A dirigé vers ce dernier.Taking into account the provisions described above, this commitment can only be made following a well-defined orientation, for which the tongue 39 of the connection connector 15 is on the same side as the step 41 of the recess 17A in the housing 12 of the electrical appliance 10A, with its lower section 39A directed towards the latter.

    Il suffit, enfin, de mettre à son tour en place sur le rail de montage 11, par encliquetage, l'appareil électrique 10B.It suffices, finally, to turn in place on the mounting rail 11, by snap-fastening, the device electric 10B.

    Tel que schématisé par la flèche F2 à la figure 13B, sur laquelle l'appareil électrique 10B n'est que schématisé en traits interrompus par son contour, cette mise en place peut se faire directement sur le connecteur de liaison 15, par pivotement autour de celui-ci.As shown by the arrow F2 in the figure 13B, on which the electrical appliance 10B is only schematically in lines interrupted by its outline, this can be done directly on the connector 15, by pivoting around of it.

    En variante, elle peut se faire à distance du connecteur de liaison 15, et il suffit ensuite de faire coulisser l'appareil électrique 10B le long du rail de montage 11 jusqu'à ce qu'il s'engage sur la partie du connecteur de liaison 15 faisant saillie du boítier 12 de l'appareil électrique 10A.Alternatively, it can be done remotely from the connector 15, and then just do slide the 10B electrical appliance along the rail assembly 11 until it engages on the part of the connector 15 projecting from the housing 12 of the electrical appliance 10A.

    Ainsi qu'il est aisé de la comprendre, cet engagement de l'appareil électrique 10B sur le connecteur de liaison 15 est rendu possible par la hauteur, appropriée à cet effet, du décrochement latéral 42' de l'évidement 17B correspondant de son boítier 12.As is easy to understand, this commitment of the 10B electrical appliance on the connector of connection 15 is made possible by the height, suitable for this purpose, from the lateral offset 42 ' of the corresponding recess 17B of its casing 12.

    Dans tous les cas, les appareils électriques 10A, 10B, une fois mis en place, sont jointifs, l'un à la suite de l'autre, et leurs boítiers 12 recouvrent donc complètement le connecteur de liaison 15.In all cases, electrical appliances 10A, 10B, once in place, are joined, one to following the other, and their cases 12 cover therefore completely the connection connector 15.

    Corollairement, leurs pistes de contact 22 ayant été disposées en conséquence, les liaisons électriques recherchées entre ces appareils électriques 10A, 10B se trouvent alors assurées par les organes de connexion 20 que comporte le connecteur de liaison 15 suivant l'invention.As a corollary, their contact paths 22 having been arranged accordingly, the links wanted electrical between these electrical devices 10A, 10B are then provided by the connection members 20 that the connector comprises link 15 according to the invention.

    En effet, par construction, la saillie D1 que forment au repos les pièces de contact 21 de ces organes de connexion 20 sur la platine 26 de l'embase 16 du connecteur de liaison 15 qui les porte, figure 6, est supérieure à la distance D2 séparant cette platine 26 de la carte ou plaquette de circuit imprimé 13 des appareils électriques 10A, 10B lorsque, figure 2, le connecteur de liaison 15 est inséré sous le boítier 12 de ceux-ci.Indeed, by construction, the projection D1 that at rest form the contact parts 21 of these connection members 20 on the plate 26 of the base 16 of the connection connector 15 which door, figure 6, is greater than the distance D2 separating this plate 26 from the card or plate 13 of electrical appliances 10A, 10B when, in FIG. 2, the connection connector 15 is inserted under the housing 12 of these.

    Compte tenu de l'élasticité de ces pièces de contact 21, celles-ci se trouvent alors élastiquement appliquées aux pistes de contact 22 concernées, leur implantation ayant été prévue en conséquence.Given the elasticity of these pieces of contact 21, these are then resiliently applied to the contact tracks 22 concerned, their establishment having been planned accordingly.

    Il va de soi, cependant, que l'invention n'est pas limitée au cas où seuls deux appareils électriques 10A, 10B sont ainsi concernés.It goes without saying, however, that the invention is not not limited to the case where only two electrical devices 10A, 10B are thus concerned.

    Elle peut au contraire s'étendre aussi bien à un nombre supérieur d'appareils électriques.On the contrary, it can extend as well to a higher number of electrical appliances.

    Par exemple, et tel que schématisé en traits interrompus à la figure 1, un troisième appareil électrique 10C, formant en quelque sorte une extension de l'appareil électrique 10B, peut être envisagé.For example, and as shown in lines interrupted in Figure 1, a third device electric 10C, sort of forming an extension of the electrical appliance 10B, can be envisaged.

    C'est la raison pour laquelle l'appareil électrique 10B comporte un évidement 17B, 17'B à l'une et l'autre de ses extrémités transversales.This is the reason why the electrical appliance 10B has a recess 17B, 17'B at one and the other of its transverse ends.

    Par son évidement 17'B, il peut en effet être mis en oeuvre un deuxième connecteur de liaison 15 suivant l'invention, propre à assurer entre lui et l'appareil électrique 10C les liaisons électriques nécessaires.By its 17'B recess, it can indeed be implemented a second link connector 15 according to the invention, suitable for ensuring between him and the electrical appliance 10C the electrical connections required.

    Par les formes de détrompage auxquelles correspond la languette 39 d'un tel connecteur de liaison 15, il est impossible, en pratique, qu'un raccordement direct soit établi entre par exemple un appareil électrique 10A et un appareil électrique 10C.By the forms of polarization to which corresponds the tongue 39 of such a connector link 15, it is impossible in practice for a direct connection is established between for example a 10A electrical appliance and an electrical appliance 10C.

    Tous les appareils électriques portant en façade des indications à lire et devant de ce fait être tous mis en place suivant une même orientation sur le rail de montage 11, il n'y a à ce sujet aucune ambiguïté.All electrical appliances bearing on the front indications to read and therefore before be all set up in the same orientation on mounting rail 11 there is about this no ambiguity.

    En pratique, pour les liaisons électriques à établir entre l'appareil électrique 10B et l'appareil électrique 10C qui en forme une extension, un nombre d'organes de connexion 20 supérieur à trois peut être nécessaire.In practice, for electrical connections to establish between the electrical appliance 10B and the appliance electric 10C which forms an extension, a number of connection members 20 greater than three may be required.

    C'est la raison pour laquelle l'embase 16 du connecteur de liaison 15 suivant l'invention comporte en attente un nombre supérieur d'évidements 25.This is the reason why the base 16 of the connection connector 15 according to the invention comprises waiting for a higher number of recesses 25.

    En variante des dispositions précédentes, les organes de connexion que comporte le connecteur de liaison suivant l'invention, au lieu d'être constitués d'épingles intervenant à la manière de frotteurs, comme plus particulièrement décrit et représenté, pourraient consister par exemple en des pinces venant s'embrocher sur l'extrémité de la carte ou plaquette de circuit imprimé correspondante.As a variant of the preceding provisions, the connection elements that the connector comprises of connection according to the invention, instead of being constituted pins acting like wipers, as more particularly described and represented, could consist for example of pliers coming to engage on the end of the corresponding printed circuit board or board.

    De même, la mise en oeuvre d'une telle carte ou plaquette de circuit imprimé n'est pas indispensable, et il pourrait lui être substitué des pistes de contact spécifiques, auxquelles les constituants concernés seraient chacun individuellement raccordés de manière appropriée.Similarly, the implementation of such a card or printed circuit board is not essential, and it could be substituted for it tracks of specific contacts, to which the constituents concerned would each be individually connected appropriately.

    A la figure 14 est représenté un dispositif de liaison 45 susceptible d'être mis en oeuvre lorsque les appareils électriques à relier ne sont pas disposés sur le même rail de montage mais sur des rails de montage distincts.In Figure 14 is shown a device for link 45 capable of being implemented when the electrical devices to be connected are not arranged on the same mounting rail but on rails separate mounting.

    Ce dispositif de liaison 45 se compose de deux appareils électriques 46 reliés par un cordon 47.This connection device 45 consists of two electrical appliances 46 connected by a cord 47.

    Ces appareils électriques 46, qui, en pratique, sont identiques entre eux, et dont le contour, en élévation, est à l'image de celui des appareils électriques 10 précédents, se réduisent chacun à un simple boítier 48 propre à la mise en oeuvre d'un connecteur de liaison suivant l'invention.These electrical appliances 46, which, in practice, are identical to each other, and whose outline, in elevation, is like that of the devices electric 10 previous, each reduce to a simple box 48 suitable for implementation of a connection connector according to the invention.

    Ce boítier 48 présente donc, à sa base, à l'une au moins de ses extrémités transversales, et, en pratique, à une seule de celles-ci, un évidement 17, dans lequel peut être engagé un tel connecteur de liaison, et dans lequel débouchent la ou les pistes de contact 22 correspondantes, non visibles sur la figure.This housing 48 therefore presents, at its base, to one at least of its transverse ends, and, in practice, to only one of these, a recess 17, in which such a connector can be engaged of connection, and into which the opening (s) corresponding contact tracks 22, not visible on the face.

    En pratique, le seul constituant alors desservi par un tel appareil électrique 46 est le cordon 47 qui le relie électriquement à l'autre, ou, plus précisément, les conducteurs électriques constituant ce cordon 47, ces conducteurs électriques étant convenablement reliés à la ou aux pistes de contact 22 concernées.In practice, the only constituent then served by such an electrical appliance 46 is the cord 47 which electrically connects it to the other, or, more precisely, the electrical conductors constituting this cord 47, these electrical conductors being suitably connected to the runway (s) contact 22 concerned.

    Pour le soutien d'un connecteur de liaison suivant l'invention, il est prévu, à la base de l'évidement 17 de chacun des appareils électriques 46, en saillie à compter de la butée 44, non visible sur la figure, correspondante, une languette 49.To support a following link connector the invention, it is provided, at the base of the recess 17 of each of the electrical appliances 46, protruding from the stop 44, not visible on the corresponding figure, a tongue 49.

    Par des crochets 50 qu'ils présentent latéralement à cet effet, ces appareils électriques 46 sont chacun propres à être individuellement encliquetés sur un appareil électrique 10.By hooks 50 which they present laterally for this purpose, these electrical appliances 46 are each suitable for being snapped on individually on an electrical appliance 10.
