Description

La présente invention concerne un bornier à raccordement rapide, par enfichage direct des conducteurs, équipant des appareils électriques modulaires et constitué essentiellement d'un guide conducteur, d'une lame ressort destinée à plaquer les conducteurs contre ledit guide, et d'un organe de commande permettant la libération desdits conducteurs.The present invention relates to a quick connection terminal block, by direct plug-in of conductors, fitted to electrical devices modular and essentially consisting of a conductive guide, a blade spring intended to press the conductors against said guide, and of a member control allowing the release of said conductors.

De tels borniers sont, dans leur principe, connus depuis longtemps et ne sont pas, en tant que tels, l'objet de la présente invention, qui a trait aux modalités particulières de leur application à des appareils électriques modulaires standard.In principle, such terminal blocks have been known for a long time and do not are not, as such, the subject of the present invention, which relates to specific procedures for their application to electrical appliances standard modular.

L'art antérieur montre que l'utilisation combinée de borniers à raccordement rapide et d'appareils modulaires est connue, comme en témoigne notamment le brevet japonais publié sous le numéro 10074543A. Dans ce document, le bornier à raccordement rapide est totalement intégré dans le boítier de l'appareil et utilisable via un orifice pratiqué dans une petite face latérale dudit boítier, en face du couple guide conducteur / lame ressort. Un autre orifice situé dans la façade du produit permet l'accès à un organe de commande déverrouillant la liaison.The prior art shows that the combined use of terminal blocks with connection fast and modular device is known, as evidenced in particular Japanese patent published under number 10074543A. In this document, the quick connection terminal block is fully integrated in the the device and usable via an opening made in a small side face of said housing, opposite the driver guide / leaf spring pair. Another hole located in the front of the product allows access to a control device unlocking the link.

En fait, le bornier à raccordement rapide est dans ce cas traité de la même manière que les bomiers de raccordement classiques à cage, du moins en termes de positionnement et d'accès à l'intérieur de l'appareil. Eu égard aux conditions d'utilisation usuelles des appareils modulaires, cela ne permet cependant qu'une exploitation imparfaite des capacités et potentionnalités offertes par les borniers à raccordement rapide. In fact, the quick connection terminal block is treated the same in this case in the same way as conventional cage connecting beams, at least in terms of positioning and access to the interior of the device. Having regard to usual conditions of use for modular devices, this does not allow however, that an imperfect exploitation of capacities and potentialities offered by quick connect terminal blocks.

Pour un appareil modulaire disposé sur son rail dans une armoire électrique classique, il faut en effet d'abord accéder à l'orifice conduisant à son tour au bornier, pour bénéficier des avantages que ce dernier offre. Or, les monteurs savent bien que dans de multiples cas, lesdits orifices sont malaisément accessibles parce que, par exemple, orientés vers le bas, et/ou situés à une hauteur telle que le monteur doit se baisser pour visualiser l'orifice, voire encore localisés à proximité de la paroi inférieure de l'armoire, etc...For a modular device placed on its rail in an electrical cabinet classic, you must first access the orifice leading in turn to the terminal block, to benefit from the advantages that the latter offers. The fitters know well that in many cases, said orifices are awkwardly accessible because, for example, facing downwards, and / or located at a height such as the fitter must bend down to view the orifice, or even located near the wall bottom of the cabinet, etc ...

En somme, proposer un bornier à connexion rapide sans par ailleurs se préoccuper de son accessibilité revient de facto à priver l'utilisateur, dans nombre de cas, de ses qualités intrinsèques.In short, offer a quick connection terminal block without otherwise worrying about its accessibility amounts to de facto depriving the user, in many of cases, of its intrinsic qualities.

C'est l'inconvénient que se propose à titre principal de résoudre l'invention, en fournissant des solutions visant à faciliter considérablement la connexion en permettant un accès immédiat au bornier à raccordement rapide quelle que soit par ailleurs la position de l'appareil électrique modulaire.This is the drawback which the main objective of the invention is to solve, by providing solutions to significantly facilitate connection by allowing immediate access to the quick-connect terminal block whatever elsewhere the position of the modular electrical appliance.

A tout le moins, l'invention a pour objectif d'améliorer l'accessibilité audit bornier, en proposant des solutions graduées répondant au problème posé.At the very least, the invention aims to improve accessibility to said terminal block, by proposing graduated solutions responding to the problem posed.

Ainsi, le bornier de l'invention, constitué principalement, comme mentionné ci-dessus, d'un guide conducteur muni d'une partie plane parallèle à la direction d'enfichage des conducteurs et d'une lame ressort dont une portion inclinée est rappelée au contact de ladite portion, avec lesquels coopèrent au moins un organe de commande permettant d'écarter la portion inclinée de la lame ressort de la partie plane du guide conducteur, est caractérisé à titre principal en ce qu'il comporte des moyens pour brocher ou débrocher sans outils à tout moment le bornier respectivement à / de l'appareil électrique modulaire, l'action d'une partie de la lame ressort sur le boítier dudit appareil ou sur un élément qui en est solidaire garantissant la réalisation du contact électrique entre le guide conducteur et la borne de l'appareil électrique modulaire.Thus, the terminal block of the invention, mainly constituted, as mentioned above, a conductor guide provided with a flat part parallel to the direction for plugging in the conductors and a leaf spring, an inclined portion of which is called back in contact with said portion, with which at least one member cooperates control to move the inclined portion of the leaf spring away from the plane of the conductor guide, is mainly characterized in that it comprises means for plugging in or removing without tools at any time the terminal block respectively to / from the modular electrical device, the action of part of the blade spring on the housing of said device or on an element which is integral therewith ensuring the electrical contact between the conductor guide and the terminal of the modular electrical appliance.

L'amovibilité de borniers à connexion rapide existe également dans l'art antérieur, mais cette propriété n'a jamais jusqu'ici été développée avec le but d'optimiser la combinaison appareil électrique modulaire / bornier à raccordement rapide en vue des objectifs principaux précités.Removability of quick-connect terminal blocks also exists in the art earlier, but this property has never been developed with the aim optimize the combination of modular electrical device / connection terminal block rapid in view of the above-mentioned main objectives.

L'un des objectifs secondaires de l'invention a précisément consisté à rechercher systématiquement une telle optimisation, sur le double terrain des fonctionnalités techniques et de la commodité d'utilisation pour le monteur. One of the secondary objectives of the invention was precisely to seek systematically such an optimization, on the double ground of the functionalities techniques and convenience for the editor.

L'avantage principal de l'invention se déduit sans peine de la caractéristique essentielle précitée : quelle que soit la localisation de l'appareil modulaire, l'opérateur n'a qu'à débrocher le bomier pour procéder au raccordement.The main advantage of the invention is easily deduced from the characteristic essential above: whatever the location of the modular device, the operator only has to remove the housing to proceed with the connection.

Le brochage lui-même, immédiat et réalisable sans effort, garantit d'une part une fixation mécanique correcte au regard des contraintes mécaniques prévisibles, et d'autre part la liaison électrique entre les conducteurs externes et le "coeur" électrique de l'appareil.The pinout itself, immediate and effortless, guarantees on the one hand correct mechanical fixing with regard to foreseeable mechanical stresses, and on the other hand the electrical connection between the external conductors and the electrical "heart" of the device.

Ce sont d'ailleurs des moyens techniques partiellement communs qui assurent la fixation mécanique et la liaison électrique.These are also partially common technical means which ensure mechanical fixing and electrical connection.

Selon une variante, le guide conducteur et la lame ressort sont disposés dans un bornier insérable parallèlement à la direction d'enfichage des conducteurs, dans un logement pratiqué dans le petit côté latéral du boítier de l'appareil modulaire.Alternatively, the conductive guide and the leaf spring are arranged in a terminal block insertable parallel to the direction of insertion of the conductors, in a housing in the small side of the housing of the modular device.

Dans ce cas, de préférence, une portion flexible de la lame ressort dépasse d'une des faces du bomier, en vue de se loger élastiquement dans un évidement prévu à cet effet dans la paroi correspondante dudit logement du boítier de l'appareil électrique modulaire.In this case, preferably, a flexible portion of the leaf spring protrudes of one of the faces of the bomier, in order to be resiliently housed in a recess provided for this purpose in the corresponding wall of said housing of the housing the modular electrical appliance.

Il y a donc un clipsage, immédiat, du bomier dans le boítier de l'appareil électrique modulaire, et plus précisément dans le logement précité. Le bornier y est contenu dans sa presque totalité à l'exception le cas échéant de sa façade qui peut être prévue pour remplir une fonction additionnelle de guidage qui sera expliquée plus en détail dans la suite. Il n'est nul besoin d'une portion sur laquelle exercer une prise pour retirer le bomier, car les conducteurs enfichés dans celui-ci peuvent être utilisés à ce effet.There is therefore an immediate clipping of the case in the case of the device modular electric, and more precisely in the aforementioned housing. The terminal block y is almost entirely contained with the exception, where appropriate, of its facade which may be provided to fulfill an additional guidance function which will be explained in more detail below. There is no need for a portion on which take a hold to remove the bomier, because the conductors plugged into it can be used for this purpose.

Selon l'invention, le guide conducteur affleure la face du bornier opposée à celle qui présente la portion saillante de lame ressort, et il est maintenu au contact de la borne de l'appareil électrique modulaire, laquelle affleure la paroi correspondante du logement, grâce à l'action de ladite portion flexible de la lame ressort sur le fond de l'évidement.According to the invention, the conductor guide is flush with the face of the terminal block opposite to that which has the protruding portion of the leaf spring, and it is kept in contact with the modular electrical device terminal, which is flush with the corresponding wall of the housing, thanks to the action of said flexible portion of the leaf spring on the bottom of the recess.

Dans cette configuration de l'invention, la face comprenant le guide conducteur comporte en outre au moins un orifice traversant permettant le passage d'au moins un bras de l'organe de commande équipant le boítier de l'appareil électrique modulaire, le ou lesdits bras étant reliés à un bouton de commande accessible de la façade de celui-ci.In this configuration of the invention, the face comprising the conductor guide further includes at least one through hole allowing the passage of at least an arm of the control member fitted to the housing of the electrical appliance modular, the said arm or arms being connected to a control button accessible from the facade of it.

En somme, le bornier débrochable ne comprend dans cette configuration pas d'organe de commande, et par conséquent pas tous les éléments d'un dispositif à raccordement rapide tels qu'énumérés ci-dessus, pour la raison simple que la direction de brochage du bornier et celle du déplacement de l'organe de commande sont d'une part sensiblement perpendiculaires, et qu'ils sont d'autre part accessibles depuis deux faces distinctes du boítier de l'appareillage électrique modulaire.In short, the removable terminal block does not include in this configuration control unit, and therefore not all the elements of a device to quick connection as listed above, for the simple reason that the direction of terminal block assignment and direction of movement of the on the one hand are substantially perpendicular, and on the other hand they are accessible from two separate sides of the electrical equipment box Modular.

Selon une possibilité, la périphérie du bouton est munie d'une patte élastique avec un crochet d'extrémité permettant son clipsage dans le boítier de l'appareil électrique modulaire, ledit crochet comportant deux surfaces parallèles venant en butée contre deux cloisons dudit boítier pour limiter la course des organes de commande.According to one possibility, the periphery of the button is provided with an elastic tab with an end hook allowing it to be clipped into the housing of the device modular electric, said hook comprising two parallel surfaces coming in abutment against two partitions of said housing to limit the travel of the organs of ordered.

Cette caractéristique permet en fait de clipser les organes de commande de l'extérieur du boítier de l'appareil électrique modulaire, lorsque celui-ci est fermé.This characteristic makes it possible in fact to clip the control members of outside the housing of the modular electrical appliance, when the latter is closed.

De préférence, le bornier et le logement comportent chacun un élément de détrompage destinés à coopérer l'un avec l'autre, imposant le sens d'insertion du boítier dans le logement pratiqué dans le boítier de l'appareil électrique.Preferably, the terminal block and the housing each have an element of coding intended to cooperate with each other, imposing the direction of insertion of the housing in the housing in the housing of the electrical appliance.

Plus précisément, le bornier comporte une glissière en queue d'aronde située sur l'une des faces parallèles à la direction d'insertion, le logement récepteur comportant une protubérance de formé correspondante prévue pour s'y loger.More specifically, the terminal block includes a dovetail slide located on one of the faces parallel to the direction of insertion, the receiving housing having a corresponding shaped protuberance provided for housing therein.

Cette possibilité constructionnelle simplifie encore la tâche de l'opérateur, et offre une garantie supplémentaire de la réalisation immédiate des liaisons mécanique et électrique.This constructional possibility further simplifies the operator's task, and offers an additional guarantee of the immediate realization of the connections mechanical and electrical.

Selon une variante de configuration, le guide conducteur, la lame ressort et l'organe de commande sont disposés dans un bornier fixable au boítier de l'appareil électrique modulaire selon une direction perpendiculaire à la direction d'enfichage des conducteurs, pour occuper un volume ménagé à l'extrémité longitudinale de la façade de l'appareil électrique modulaire, ouvert sur ladite façade et sur le petit côté latéral dudit boítier.According to a variant configuration, the conductor guide, the leaf spring and the control member are arranged in a terminal block which can be fixed to the housing the modular electrical appliance in a direction perpendicular to the direction for plugging in the conductors to occupy a space at the end longitudinal of the facade of the modular electrical appliance, open on said facade and on the small lateral side of said housing.

Dans ce cas, le bornier comprend la totalité des éléments équipant un dispositif à raccordement rapide, car la nouvelle configuration, formant de fait une portion de la façade, s'y prête. La fixation se fait par coulissement le long d'une glissière disposée sur la paroi d'allure perpendiculaire à ladite façade, qui en constitue le fond, s'achevant au contact d'un ressaut d'allure parallèle à ladite façade, de telle sorte que le bomier fixé, en remplissant ledit volume, restitue sensiblement une forme d'appareil électrique modulaire traditionnelle.In this case, the terminal block includes all the elements equipping a device quick connection, because the new configuration, in fact forming a portion of the facade, lends itself to it. The fixing is done by sliding along a slide disposed on the wall of shape perpendicular to said facade, which constitutes the bottom, ending in contact with a step parallel to said facade, such so that the fixed bomier, by filling said volume, substantially restores a form of traditional modular electrical appliance.

Selon cette variante, le guide conducteur comporte en outre une portion parallèle à l'axe de la glissière, au niveau de laquelle la borne de l'appareil électrique est disponible, ladite portion du guide conducteur venant s'enficher entre ladite borne et le fond de la glissière.According to this variant, the conductor guide further comprises a portion parallel to the axis of the slide, at which the terminal of the device electric is available, said portion of the conductor guide plugging in between said terminal and the bottom of the slide.

De préférence, la glissière comporte deux parois parallèles en T entre lesquelles est disposée ladite borne de l'appareil électrique, à une distance du fond de la glissière sensiblement égale à l'épaisseur de la portion du guide conducteur parallèle à l'axe de la glissière.Preferably, the slide has two parallel T-shaped walls between which is arranged said terminal of the electrical apparatus, at a distance from the bottom of the slide substantially equal to the thickness of the portion of the conductor guide parallel to the axis of the slide.

La fixation mécanique du bornier, notamment réalisée par cette glissière, interfère avec l'établissement de la liaison électrique puisque les parois de la glissière encadrent et guident les contacts électriques.Mechanical fixing of the terminal block, in particular carried out by this slide, interferes with the establishment of the electrical connection since the walls of the slide frame and guide the electrical contacts.

De plus, l'extrémité de la lame ressort située à l'opposé de celle venant en appui sur la surface du guide conducteur exerce une pression élastique contre la borne de l'appareil électrique en direction du fond de la glissière.In addition, the end of the leaf spring located opposite to that coming in pressing on the surface of the conductive guide exerts an elastic pressure against the terminal of the electrical appliance towards the bottom of the slide.

Comme dans la variante précédente, la lame ressort, outre sa fonction principale de placage du conducteur contre le guide, garantit l'établissement de la liaison électrique car elle repousse la borne électrique de l'appareil contre la portion dudit guide parallèle à la glissière.As in the previous variant, the blade comes out, in addition to its main function placing the conductor against the guide, guarantees the establishment of the connection electric because it pushes the electrical terminal of the device against the portion of said guide parallel to the slide.

Dans cette configuration, comme on l'a mentionné, l'organe de commande équipe le bornier à fixer au boítier de l'appareil électrique.In this configuration, as mentioned, the control member equips the terminal block to be fixed to the casing of the electrical appliance.

Dans le cas où l'utilisateur décide de ne pas débrocher le bomier, par exemple parce que la localisation de l'appareil électrique modulaire dans l'armoire électrique est favorable (elle est par exemple située vers le haut, et très accessible), des moyens additionnels sont néanmoins proposés à l'opérateur pour faciliter la connexion des conducteurs.In the case where the user decides not to remove the case, for example because the location of the modular electrical device in the electrical cabinet is favorable (it is for example located upwards, and very accessible), additional means are nevertheless offered to the operator to facilitate the connection of conductors.

Ainsi, les faces des borniers affleurant les petits côtés latéraux des boítiers sont dotés d'un dispositif de guidage des conducteurs à raccorder, permettant le guidage de l'extrémité dénudée de chaque conducteur depuis la façade du boítier de l'appareil électrique modulaire jusqu'à connexion entre le guide conducteur et la lame ressort.Thus, the faces of the terminal blocks flush with the small lateral sides of the boxes are equipped with a guide device for the conductors to be connected, allowing guide the stripped end of each conductor from the front of the housing of the modular electrical appliance until connection between the conductor guide and the leaf spring.

Un repère dans la façade, suivi d'un double guidage, suivant deux directions distinctes, permet de faciliter considérablement le raccordement. Cette caractéristique concerne les deux variantes précitées de l'invention.A marker in the facade, followed by double guidance, in two directions separate, considerably facilitates connection. This characteristic relates to the two aforementioned variants of the invention.

Plus précisément, ces dispositifs sont constitués d'au moins une goulotte de direction parallèle à l'axe longitudinal du petit côté latéral, dont l'extrémité débouchant au niveau de la façade de l'appareil électrique modulaire réalise une encoche de repérage pour la connexion, l'autre extrémité étant fermée autour d'au moins un orifice marquant l'ouverture d'un conduit de guidage vers le lieu de la connexion entre le guide conducteur et la lame ressort.More specifically, these devices consist of at least one chute direction parallel to the longitudinal axis of the short lateral side, the end of which opening at the level of the front of the modular electrical device achieves a marking notch for connection, the other end being closed around at least minus an orifice marking the opening of a guide duct to the place of connection between the conductor guide and the leaf spring.

The invention will now be described in more detail, by means of the appended figures, for which:
  • Figure 1 is a partial perspective view of a modular electrical device provided with a housing for integrating one of the variants of the quick-connect housing according to the invention, also shown, in a withdrawn situation;

  • Figure 7 is a partially exploded perspective view of this terminal block; and
  • Figure 8 shows in perspective the main components of the bomier, in electrical connection with the terminal of the modular device.

En référence à la figure 1, le boítier (B) de l'appareil électrique modulaire comporte un logement (1) prévu pour loger le bomier (2), ledit logement s'ouvrant dans une petite face latérale (L) dudit boítier. L'insertion du bornier (2) se fait suivant la flèche (A), c'est-à-dire dans le sens d'enfichage des conducteurs, sensiblement parallèlement à l'orientation générale de la façade (F) de l'appareil modulaire.Referring to Figure 1, the housing (B) of the modular electrical appliance comprises a housing (1) designed to house the housing (2), said housing opening in a small side face (L) of said housing. The insertion of the terminal block (2) is done according to the arrow (A), that is to say in the direction of insertion of the conductors, substantially parallel to the general orientation of the facade (F) of the modular device.

Les éléments visibles équipant le boítier (1), dans le logement ou en sa proximité, sont :

  • un évidement (3) pratiqué dans la paroi inférieure du logement (2) ;
  • une excroissance en queue d'aronde (4) pour la liaison avec une gorge correspondante dans le bornier (2) ;
  • un levier de verrouillage (5) permettant la manipulation d'un organe de verrouillage (12) du bornier (2) dans le logement (1), comme il sera montré plus en détail dans la suite ; et
  • des organes de commande (6) du dispositif à raccordement rapide notamment contenu dans le bornier (2), et plus particulièrement les boutons de manipulation desdits organes (6).
The visible elements fitted to the housing (1), in the housing or in its vicinity, are:
  • a recess (3) made in the lower wall of the housing (2);
  • a dovetail protrusion (4) for connection with a corresponding groove in the terminal block (2);
  • a locking lever (5) allowing the manipulation of a locking member (12) of the terminal block (2) in the housing (1), as will be shown in more detail below; and
  • control members (6) of the quick-connect device, in particular contained in the terminal block (2), and more particularly the buttons for handling said members (6).

Le bornier (2) comporte sur sa face supérieure deux orifices jumeaux (7) destinés au passage des organes de commande (6), et notamment des bras de commande reliés aux boutons de manipulation précités, ainsi qu'une fente dans laquelle affleure une portion du guide conducteur (8).The terminal block (2) has two twin holes (7) on its upper face intended for the passage of control members (6), and in particular of the control arms control connected to the aforementioned manipulation buttons, as well as a slot in which is flush with a portion of the conductor guide (8).

Le fonctionnement combiné des trois éléments principaux du dispositif à raccordement rapide, rappelé précédemment, sera remontré à l'occasion de l'explication à suivre du fonctionnement de la seconde variante, et n'est pas nouveau en soi : un guide conducteur comporte une portion horizontale sur laquelle s'appuie élastiquement l'extrémité inclinée d'une lame ressort, au moins un organe de commande permettant le déplacement relatif de ces éléments. En l'occurrence, les organes de commande sont solidaires du boítier (B), alors que les deux autres éléments sont attachés au bomier (2).The combined operation of the three main elements of the device to quick connection, recalled previously, will be reassembled when the explanation to follow of the functioning of the second variant, and is not new in itself: a conductor guide has a horizontal portion on which rests elastically on the inclined end of a spring leaf, at least one member control allowing the relative movement of these elements. As it happens, the control members are integral with the housing (B), while the other two elements are attached to the bomier (2).

Ces derniers sont accessibles via des orifices (9) situés dans deux goulottes (10) permettant un guidage des conducteurs depuis une position située sensiblement au niveau de la façade (F) de l'appareil électrique modulaire. La figure 2 montre plus clairement en quoi consiste cette possibilité de guidage: une portion de section trapézoïdale du bornier (2) dépasse en effet du boítier (B), d'une épaisseur correspondant approximativement à celle des goulottes (10), lorsque le bomier (2) est broché dans le logement (1).These are accessible via orifices (9) located in two chutes (10) allowing guiding of the conductors from a position located substantially at the front (F) of the modular electrical appliance. The figure 2 shows more clearly what this guiding possibility consists of: a portion trapezoidal section of the terminal block (2) in fact protrudes from the housing (B), by thickness corresponding approximately to that of the troughs (10), when the bomier (2) is pinned in the housing (1).

Ces goulottes (10) présentent une ouverture orientée en direction de la façade (F), qui constitue un repère visuel pour un opérateur placé devant ladite façade, par exemple lorsque l'appareil électrique modulaire est fixé sur un rail conventionnel dans une armoire électrique. Il n'a alors qu'à y insérer l'extrémité dénudée d'un fil conducteur, laquelle sera ensuite guidée par la goulotte (10) vers l'extrémité fermée de cette dernière, où s'ouvre précisément l'ouverture (9) qui marque le début du guidage selon une seconde direction, vers l'intérieur du bornier (2) en direction de la zone de connexion entre le guide conducteur et la lame ressort flexible.These chutes (10) have an opening oriented towards the facade (F), which constitutes a visual cue for an operator placed in front of said facade, by example when the modular electrical appliance is fixed on a conventional rail in an electrical cabinet. Then he just has to insert the stripped end of a wire conductor, which will then be guided by the chute (10) towards the closed end of the latter, where precisely opens the opening (9) which marks the beginning of the guiding in a second direction, towards the inside of the terminal block (2) towards the connection area between the conductor guide and the flexible spring blade.

Cette figure 2 fait également apparaítre l'excroissance en queue d'aronde (4) insérée dans une gorge de forme adéquate, et constituant un détrompeur facilitant la tâche de l'utilisateur. Enfin, elle laisse apparaítre un autre orifice (11 ) localisé dans la paroi supérieure du bornier (2), destiné à loger un coulisseau (12) solidaire du levier (5), et déjà montrés en figure 1.This figure 2 also shows the dovetail protrusion (4) inserted into an appropriately shaped groove, and constituting a key facilitating the user task. Finally, it reveals another orifice (11) located in the upper wall of the terminal block (2), intended to accommodate a slide (12) integral with the lever (5), and already shown in Figure 1.

Lorsqu'on abaisse le levier (5), ledit coulisseau (12) se loge dans l'orifice (11 ) et verrouille le brochage du bornier (2) dans le logement (1).When the lever is lowered (5), said slide (12) is housed in the orifice (11) and locks the terminal block pinout (2) in the housing (1).

En référence à la figure 3, ledit coulisseau (12) apparaít très clairement. L'orientation de cette figure montre la paroi inférieure du bornier (2), dont dépasse une portion flexible de la lame élastique (13), prévue pour coopérer avec l'évidement (3) précité. La profondeur de ce dernier est prévue, en combinaison avec la distance dont saille la lame ressort (13), pour que le bornier (2) soit rappelé constamment au contact de la paroi supérieure du logement (1), laquelle comporte, affleurant, la borne (14) de l'appareil électrique modulaire, au même niveau que le guide conducteur (8) sur le bornier (2).Referring to Figure 3, said slide (12) appears very clearly. The orientation of this figure shows the bottom wall of the terminal block (2), of which protrudes a flexible portion of the elastic blade (13), designed to cooperate with the aforementioned recess (3). The depth of the latter is provided, in combination with the distance from which protrudes the leaf spring (13), so that the terminal block (2) is recalled constantly in contact with the upper wall of the housing (1), which comprises, flush with the terminal (14) of the modular electrical appliance, at the same level as the conductor guide (8) on the terminal block (2).

Ce mécanisme assure donc le contact entre ledit guide (8) et par conséquent les conducteurs insérés dans le bornier (2), et l'appareil électrique modulaire proprement dit. La même paroi supérieure du logement comprend des orifices (15) de passage des bras (non visibles) des organes de commande (6).This mechanism therefore ensures contact between said guide (8) and therefore the conductors inserted in the terminal block (2), and the modular electrical appliance well said. The same upper wall of the housing includes orifices (15) for passage of the arms (not visible) of the control members (6).

Cette figure fait enfin apparaítre dans le bornier (2) la gorge (16) de réception de l'excroissance (4) en queue d'aronde.This figure finally shows in the terminal block (2) the groove (16) for reception of the dovetail protrusion (4).

Les figures suivantes concernent la seconde variante, à fixation perpendiculaire à la direction d'insertion des conducteurs. Dans ce cas, le boítier (B) est partiellement tronqué à l'une de ses extrémités longitudinales, au-dessus d'un ressaut (21) sur lequel vient s'appuyer le bornier (22) dont la paroi supérieure, comportant un organe de commande (26), forme de fait une partie de la façade (F) de l'appareil électrique modulaire. La totalité des composants essentiels d'un dispositif à raccordement rapide est donc cette fois comprise dans le bornier (22).The following figures relate to the second variant, with perpendicular fixing to the direction of insertion of the conductors. In this case, the housing (B) is partially truncated at one of its longitudinal ends, above a projection (21) on which the terminal block (22) rests, the upper wall of which, comprising a control member (26), in fact forms part of the facade (F) of the modular electrical appliance. All the essential components of a quick connection device is therefore this time included in the terminal block (22).

Le ressaut (21) comporte des moyens mécaniques de fixation du bornier (22), à savoir une glissière (24) comportant deux murets (23) identiques entre lesquels se trouve la borne (25) de l'appareil électrique. La figure 5 montre un agrandissement du bornier (22), laissant voir une identité des structures des systèmes de guidage de l'extrémité dénudée des conducteurs dans les deux variantes. Il s'agit des mêmes goulottes (30) débouchant à leur extrémité supérieure au niveau de la façade, et closes à leur extrémité inférieure à proximité d'une ouverture (29) marquant le début des conduits d'accès aux lieux de connexion proprement dits.The projection (21) comprises mechanical means for fixing the terminal block (22), namely a slide (24) comprising two identical walls (23) between which is the terminal (25) of the electrical appliance. Figure 5 shows a extension of the terminal block (22), revealing an identity of the structures of the guide systems for the stripped ends of the conductors in both variants. These are the same chutes (30) opening at their ends higher at the level of the facade, and closed at their lower end near an opening (29) marking the beginning of the access conduits to the places of connection proper.

La figure 6 donne une incidence de visualisation différente, intéressante car elle permet de relier la structure de la partie arrière du bornier (22) et le système à glissière évoqué ci-dessus. Un évidement (31) est pratiqué dans cette partie arrière, à la croisée des parois inférieure (27) et arrière (28) du bornier (22). Cet évidement (31) a une forme prévue pour loger la glissière (24), par coulissement relatif. Y apparaissent en outre une portion du guide conducteur (32) et de la lame ressort (33), ménageant entre eux un volume résiduel dans lequel peut s'insérer la borne (25). Figure 6 gives a different viewing incidence, interesting because it used to connect the structure of the rear part of the terminal block (22) and the system slide mentioned above. A recess (31) is made in this part rear, at the cross of the lower (27) and rear (28) walls of the terminal block (22). This recess (31) has a shape intended to accommodate the slide (24), by sliding relative. A portion of the conductor guide (32) and of the blade also appear there. spring (33), leaving between them a residual volume in which the terminal (25).

La disposition relative de l'extrémité libre (32) du guide conducteur du dispositif à raccordement rapide et celle (33) de la lame ressort est telle qu'à l'installation du bornier, par coulissement, la borne (25) prend place entre lesdites extrémités libres. La portion (33) tend à plaquer la borne (25) contre le guide (32), assurant ainsi le bon contact entre eux.The relative arrangement of the free end (32) of the conductive guide of the device with quick connection and that (33) of the leaf spring is such that when installing the terminal block, by sliding, the terminal (25) takes place between said ends free. The portion (33) tends to press the terminal (25) against the guide (32), ensuring thus the good contact between them.

Les figures 7 et 8 rappellent la structure du bornier à raccordement rapide dans le contexte de sa variante référencée (22). Les mêmes éléments se retrouvent dans la variante précédente, bien entendu adaptés à la configuration spécifique de celle-ci.Figures 7 and 8 show the structure of the quick-connect terminal block in the context of its variant referenced (22). The same elements are found in the previous variant, of course adapted to the specific configuration of it.

Ainsi, un guide conducteur de référence générale (34) comporte, outre l'extrémité (32) précitée, une portion plane (35) au contact de laquelle se trouve l'extrémité d'une portion inclinée (36) de la lame ressort (37), dont on a déjà vu la fonction de la seconde extrémité (33).Thus, a general reference conductor guide (34) comprises, in addition to the aforementioned end (32), a flat portion (35) in contact with which is the end of an inclined portion (36) of the spring blade (37), of which we have already seen the function of the second end (33).

Un bras (38), issu du bouton de l'organe de commande (26), agit via un orifice pratiqué dans ladite portion plane (35) sur la lame ressort (36), pour l'écarter du guide conducteur.An arm (38), coming from the button of the control member (26), acts via an orifice made in said flat portion (35) on the leaf spring (36), to separate it from the driver guide.

Une coupelle (39) située à la base dudit bouton fixe la longueur de la course de l'organe de commande (26) par butée contre deux surfaces, d'une part la paroi supérieure du bornier (22), et d'autre part une cloison intermédiaire (40).A cup (39) located at the base of said button fixes the length of the travel of the control member (26) by abutment against two surfaces, on the one hand the wall upper of the terminal block (22), and on the other hand an intermediate partition (40).

La réalisation du bornier (22) en deux demi-coques symétriques est commode du point de vue de la fabrication, car il suffit d'insérer les composants précités, selon un même axe, dans l'une des demi-coques, et de refermer la structure par fixation sur la première de la seconde demi-coque.The realization of the terminal block (22) in two symmetrical half-shells is convenient from the manufacturing point of view, because it suffices to insert the aforementioned components, according to the same axis, in one of the half-shells, and to close the structure by fixing on the first of the second half-hull.

L'apport de la figure 8 consiste en la clarification du positionnement relatif des portions (33), (32) respectivement de la lame ressort (37) et du guide conducteur (34), et de la borne (25) intégrée à l'appareil électrique modulaire.The contribution of Figure 8 consists in clarifying the relative positioning of the portions (33), (32) respectively of the leaf spring (37) and of the conductor guide (34), and the terminal (25) integrated into the modular electrical appliance.

Les exemples de configuration donnés ci-dessus ne doivent bien entendu pas être considérés comme exhaustifs de l'invention. Celle-ci englobe au contraire toutes les variantes de forme, de configuration et de matériaux qui sont à la portée de l'homme de l'art.The configuration examples given above should of course not be considered exhaustive of the invention. On the contrary, it includes all variations of shape, configuration and materials that are within reach of those skilled in the art.
