Description

La présente invention concerne de façon générale un dispositif de distribution électrique à connexion rapide qui est constitué par un rail horizontal, allongé et de section constante, destiné à supporter des conducteurs électriques, et par au moins un boîtier destiné à venir se fixer de façon amovible le long dudit rail.The present invention generally relates to an electrical distribution device with quick connection which is constituted by a horizontal rail, elongated and of constant section, intended to support electrical conductors, and by at least one housing intended to be fixed detachably. along said rail.

L'invention peut être appliquée à la distribution basse tension.The invention can be applied to low voltage distribution.

Il est connu d'installer dans une habitation ou un local quelconque des rails qui longent les murs et de disposer à volonté le long de ces rails des boîtiers renfermant des prises électriques. On peut ainsi effectuer une installation définitive des fils électriques d'alimentation des prises, ces fils électriques passant dans ou le long des rails, et fixer ensuite les prises à l'endroit souhaité, en un nombre souhaité, ces prises pouvant être aisément raccordées aux fils électriques qui longent les rails. On peut ultérieurement supprimer au moins l'une de ces prises ou la déplacer sur le rail. Par prise électrique, on entend de façon générale tous les éléments connectables, raccordés électriquement soit à des fils d'alimentation en courant électrique, soit à des câbles spéciaux permettant d'acheminer des ondes électromagnétiques, des signaux électriques quelconques analogiques ou numériques, des signaux optiques, etc ... Ces dispositifs connus sont généralement appelés dispositifs de distribution électrique. Dans le cas le plus fréquent où la tension dans les fils électriques n'excède pas la tension d'alimentation du réseau basse tension, ces dispositifs peuvent être appelés dispositifs de distribution électrique basse tension. Leur application peut être industrielle ou domestique.It is known practice to install rails which run along the walls in any dwelling or room and to have boxes along these rails at will containing electrical sockets. It is thus possible to carry out a final installation of the electrical supply wires for the sockets, these electrical wires passing in or along the rails, and then fix the sockets at the desired location, in a desired number, these sockets being able to be easily connected to the electric wires running along the rails. You can later remove at least one of these sockets or move it on the rail. By electrical outlet, we mean in general all the connectable elements, electrically connected either to electric power supply wires, or to special cables allowing to convey electromagnetic waves, any analog or digital electrical signals, signals optics, etc. These known devices are generally called electrical distribution devices. In the most frequent case where the voltage in the electrical wires does not exceed the supply voltage of the low-voltage network, these devices can be called low-voltage electrical distribution devices. Their application can be industrial or domestic.

Les dispositifs connus de distribution électrique présentent l'inconvénient qui réside en ce que les opérations nécessaires pour effectuer la fixation mécanique d'un boîtier sur le rail et la connexion électrique des bornes de la prise incluse dans le boîtier et d'au moins un des fils électriques qui longent le rail sont des opérations complexes. D'autre part, si l'on souhaite ôter un boîtier fixé et connecté à un rail ou si l'on souhaite déplacer ce boîtier le long du rail, il est généralement nécessaire d'intervenir sur le ou les fils électriques qui ont été initialement connectés à ce boîtier afin de restaurer la continuité du ou des fils électriques ou de restaurer leur isolation électrique, essentiellement au niveau de l'emplacement initial du boîtier. Un autre inconvénient réside dans le fait qu'il est nécessaire d'extraire au moins en partie les fils électriques qui longent le rail afin de les examiner (de vérifier leur couleur ou leur calibre) afin de connecter les bons fils électriques aux bonnes bornes de la prise qui est incluse dans le boîtier. Il en résulte des risques d'erreurs de connexion, un temps de manipulation et d'installation des boîtiers sur le rail relativement long ainsi qu'une certaine détérioration des fils électriques qui longent le rail du fait que l'on est obligé de les écarter légèrement pour les contrôler. D'autre part, les fils électriques qui longent le rail ne peuvent pas être fixés à demeure d'une façon très rigide, par exemple ces fils ne peuvent pas être collés au rail sur toute leur longueur.The known electrical distribution devices have the drawback that the operations necessary to effect the mechanical fixing of a housing to the rail and the electrical connection of the terminals of the socket included in the housing and of at least one of the electrical wires running along the rail are complex operations. On the other hand, if one wishes to remove a box fixed and connected to a rail or if one wishes to move this box along the rail, it is generally necessary to intervene on the electric wire or wires which were initially connected to this box in order to restore the continuity of the electric wire (s) or to restore their electrical insulation, essentially at the level of the initial location of the box. Another disadvantage lies in the fact that it is necessary to at least partially extract the electric wires which run along the rail in order to examine them (to verify their color or their gauge) in order to connect the good electric wires to the good terminals of the plug which is included in the housing. This results in risks of connection errors, a relatively long time for handling and installing the boxes on the rail, as well as a certain deterioration of the electrical wires which run along the rail due to the fact that we have to keep them apart. slightly to control them. On the other hand, the electrical wires which run along the rail cannot be fixed permanently in a very rigid manner, for example these wires cannot be glued to the rail over their entire length.

Un objet de la présente invention consiste à proposer un dispositif de distribution qui permet une fixation amovible d'un boîtier sur un rail, cette fixation amovible pouvant être manoeuvrée aisément, tout en étant particulièrement efficace, simple, esthétique et peu coûteuse à réaliser.An object of the present invention is to provide a dispensing device which allows a removable fixing of a housing on a rail, this removable fixing being able to be easily operated, while being particularly effective, simple, aesthetic and inexpensive to produce.

Sur la figure 1, on distingue une partie d'un rail 1, un premier boîtier d'un premier type 2 qui est monté sur le rail 1 et un second boîtier d'un second type 3 qui est situé à proximité du rail 1 dans une position qui précède son montage sur le rail 1. Les boîtiers 2 et 3 diffèrent uniquement par le type de prise électrique qu'ils incluent. Le rail 1 est un profilé qui a une section en coupe en forme générale de L. Plus exactement, le rail 1 comprend une embase 4 qui a la forme générale d'une bande plane allongée disposée sensiblement horizontalement et une plaque de montage 5 qui a la forme générale d'une bande plane allongée disposée sensiblement verticalement. Les boîtiers 2 ou 3 comportent pareillement une partie inférieure comprenant essentiellement une gorge 6 dans laquelle vient se loger la plaque de montage 2 du rail 1 lorsque le boîtier est monté sur le rail 1. La structure du boîtier sera décrite plus en détail par la suite. Sur la face arrière 7 de la plaque de montage 5 du rail 1, est fixé un câble plat multiconducteur 8 qui est ainsi disposé parallèlement au rail 1 sur toute sa longueur. Le rail 1 peut être en un ou plusieurs tronçons, les tronçons étant raccordés bout à bout d'une manière quelconque connue (non représentée) et les fils électriques du câble multiconducteur étant continus ou interconnectés d'une façon quelconque connue. Le rail 1 est généralement disposé contre ou au voisinage d'un mur d'une habitation ou d'un local quelconque et est fixé au sol, au mur ou à une pièce intermédiaire d'une façon quelconque connue. Des pièces de raccord d'angle classiques (non représentées) peuvent être prévues dans les angles du local pour raccorder deux rails identiques 1 longeant deux murs perpendiculaires.In Figure 1, there is a part of a rail 1, a first housing of a first type 2 which is mounted on the rail 1 and a second housing of a second type 3 which is located near the rail 1 in a position which precedes its mounting on the rail 1. The boxes 2 and 3 differ only in the type of electrical outlet they include. Rail 1 is a profile which has a cross section in the general shape of L. More precisely, rail 1 comprises a base 4 which has the general shape of an elongated flat strip arranged substantially horizontally and a mounting plate 5 which has the general shape of an elongated flat strip arranged substantially vertically. The boxes 2 or 3 likewise have a lower part essentially comprising a groove 6 in which the mounting plate 2 of the rail 1 is housed when the box is mounted on the rail 1. The structure of the box will be described in more detail below. . On the rear face 7 of the mounting plate 5 of the rail 1, is fixed a multiconductor flat cable 8 which is thus arranged parallel to the rail 1 over its entire length. The rail 1 can be in one or more sections, the sections being connected end to end in any known manner (not shown) and the electrical wires of the multiconductor cable being continuous or interconnected in any known way. The rail 1 is generally disposed against or in the vicinity of a wall of a dwelling or any room and is fixed to the ground, to the wall or to an intermediate piece in any known way. Conventional corner connection pieces (not shown) can be provided in the corners of the room to connect two identical rails 1 running along two perpendicular walls.

Sur la figure 2, on distingue en vue de face une partie du rail 1 de la figure 1 et le boîtier 3 de la figure 1, ce boîtier 3 étant disposé au-dessus du rail 1 dans une position qui précède son montage sur le rail 1. La figure 3 est une vue en coupe transversale du rail 1 et du boîtier 3, selon la ligne I-I de la figure 2. Sur la figure 3, on distingue un mur vertical 10 qui appartient au local dans lequel on souhaite installer le dispositif de distribution selon l'invention ainsi qu'une goulotte 11 (représentée schématiquement en traits mixtes). La goulotte 11 peut être de forme quelconque et peut être fixée sur le sol, sur le mur ou sur toute autre pièce intermédiaire. La goulotte 11 sert généralement à contenir et à guider des câbles électriques tout en supportant rigidement le rail 1. Il est entendu également que le rail 1 peut être partie intégrée de la goulotte 11. La goulotte 11 ne fait pas partie du dispositif de distribution selon l'invention et peut dans certains cas ne pas être associée à ce dispositif. Si la goulotte 11 est absente, le rail 1 peut être fixé directement au sol ou à une pièce intermédiaire elle-même fixée au sol ou au mur 10. En général, le rail 1 est fixé rigidement au niveau de sa surface inférieure 12 de son embase 4 ou peut être intégrée d'un quelconque support. Le boîtier 3 comprend une partie supérieure 14 et une partie inférieure 15. La partie supérieure 14 inclut un moyen de connexion électrique 16 qui peut être d'un modèle et d'une fonction quelconque, par exemple un socle de prise électrique. La partie inférieure 15 comprend une paroi arrière 17 et une paroi avant 18 qui est parallèle à la paroi arrière 17. La partie inférieure 15 présente ainsi une section transversale en forme générale de U renversé, de façon à former la gorge 6 dans laquelle vient s'engager la plaque de montage 5 du rail 1 lorsque le boîtier 3 vient se monter de façon amovible sur le rail 1. Le câble multiconducteur 8 est de forme relativement plate, c'est-à-dire qu'il se présente sous la forme d'une bande allongée, ce qui permet sa fixation aisée, par exemple par clipsage ou par collage contre la face arrière 7 de la plaque de montage 5 du rail 1. Le câble multiconducteur 8 peut cependant être fixé mécaniquement par tout autre moyen à la plaque de montage 5, cette fixation mécanique pouvant être amovible ou démontable. Le câble 8 peut contenir au moins un fil électrique mais comporte en général au moins trois fils électriques ou plus, par exemple cinq fils électriques, comme cela est représenté sur la figure 3. Sur la paroi avant 18 de la partie inférieure 15 du boîtier 3, est montée de façon pivotante une came 20 qui est logée dans une fenêtre 21 ménagée dans cette paroi 18. La surface de came 22 débouche dans la gorge 6 de la partie inférieure 15 du boîtier 3, et la came 20 comprend en outre une manette 22 qui est située à l'extérieur du boîtier 3, à l'avant de celui-ci. La came 20 peut pivoter autour d'un axe 23 qui est sensiblement horizontal et parallèle à la paroi avant 18. La came 20 peut pivoter en tournant d'environ 90° entre une première position (représentée sur la figure 3) dans laquelle la manette 20 est abaissée et se projette sensiblement horizontalement vers l'avant du boîtier 3 et une seconde position (représentée sur la figure 5) dans laquelle la manette est relevée et s'étend sensiblement verticalement. Dans la première position qui est représentée sur la figure 3, on voit que la surface de came 21 ne s'engage pas ou pratiquement pas dans la gorge 6 du boîtier 3. Ceci permet de pouvoir monter le boîtier 3 sur le rail 1 en abaissant le boîtier 3 de façon à ce que l'ensemble constitué par la plaque de montage 5 du rail 1 et par le câble multiconducteur 8 collé à l'arrière de la plaque de montage 5 s'engage dans la gorge 6 qui correspond à l'espace qui sépare la paroi arrière 17 et la paroi avant 18 de la partie inférieure 15 du boîtier 3.In Figure 2, there is a front view of a portion of the rail 1 of Figure 1 and the housing 3 of Figure 1, this housing 3 being disposed above the rail 1 in a position which precedes its mounting on the rail 1. Figure 3 is a cross-sectional view of the rail 1 and the housing 3, along line II of the figure 2. In Figure 3, there is a vertical wall 10 which belongs to the room in which one wishes to install the dispensing device according to the invention and a chute 11 (shown schematically in phantom). The chute 11 can be of any shape and can be fixed to the floor, the wall or any other intermediate piece. The chute 11 generally serves to contain and guide electrical cables while rigidly supporting the rail 1. It is also understood that the rail 1 can be an integrated part of the chute 11. The chute 11 is not part of the distribution device according to the invention and may in some cases not be associated with this device. If the chute 11 is absent, the rail 1 can be fixed directly to the ground or to an intermediate piece itself fixed to the ground or to the wall 10. In general, the rail 1 is rigidly fixed at its lower surface 12 of its base 4 or can be integrated with any support. The housing 3 comprises an upper part 14 and a lower part 15. The upper part 14 includes an electrical connection means 16 which can be of any model and function, for example an electrical socket. The lower part 15 comprises a rear wall 17 and a front wall 18 which is parallel to the rear wall 17. The lower part 15 thus has a cross section in the general shape of an inverted U, so as to form the groove 6 in which comes 'Engage the mounting plate 5 of the rail 1 when the housing 3 is removably mounted on the rail 1. The multicore cable 8 is relatively flat in shape, that is to say it is in the form an elongated strip, which allows its easy fixing, for example by clipping or by gluing against the rear face 7 of the mounting plate 5 of the rail 1. The multicore cable 8 can however be mechanically fixed by any other means to the mounting plate 5, this mechanical fixing being able to be removable or dismountable. The cable 8 can contain at least one electric wire but generally comprises at least three or more electric wires, for example five electric wires, as shown in FIG. 3. On the front wall 18 of the lower part 15 of the housing 3 , is pivotally mounted a cam 20 which is housed in a window 21 formed in this wall 18. The cam surface 22 opens into the groove 6 of the lower part 15 of the housing 3, and the cam 20 further comprises a lever 22 which is located outside the housing 3, at the front thereof. The cam 20 can pivot around an axis 23 which is substantially horizontal and parallel to the front wall 18. The cam 20 can pivot by turning approximately 90 ° between a first position (shown in FIG. 3) in which the lever 20 is lowered and projects substantially horizontally towards the front of the housing 3 and a second position (shown in FIG. 5) in which the lever is raised and extends substantially vertically. In the first position which is shown in FIG. 3, it can be seen that the cam surface 21 does not or practically not engage in the groove 6 of the housing 3. This makes it possible to be able to mount the housing 3 on the rail 1 by lowering the housing 3 so that the assembly constituted by the mounting plate 5 of the rail 1 and by the multi-conductor cable 8 glued to the rear of the mounting plate 5 engages in the groove 6 which corresponds to the space which separates the rear wall 17 and the front wall 18 from the lower part 15 of the housing 3.

Sur les figures 4 et 5, on voit le boîtier 3 qui est monté sur le rail 1 et on voit que la manette 22 a été relevée afin de faire tourner la came 20 d'environ 90° dans le sens contraire des aiguilles d'une montre. Ce pivotement de la came 20 fait en sorte que la came 20 pousse (vers la gauche sur les dessins en coupe) la plaque de montage 5 du rail 1 de telle sorte que le câble multiconducteur 8 vienne s'appliquer contre la paroi arrière 17 du boîtier 3. Les dimensions de l'ensemble du mécanisme peuvent être déterminées de façon à ce que, dans cette position montée, la came 20 exerce un effort permanent de serrage ou de pincement de la plaque de montage 5 et du câble multiconducteur 8 afin de constituer une fixation rigide du boîtier 3 sur le rail 1. Une certaine élasticité de la paroi arrière 17 et de la paroi avant 18 permet aisément de réaliser un tel pincement afin d'établir une liaison rigide démontable du boîtier 3 sur le rail 1.In Figures 4 and 5, we see the housing 3 which is mounted on the rail 1 and we see that the handle 22 has been raised to rotate the cam 20 by about 90 ° counterclockwise. This pivoting of the cam 20 causes the cam 20 to push (to the left in the sectional drawings) the mounting plate 5 of the rail 1 so that the multi-conductor cable 8 comes to bear against the rear wall 17 of the housing 3. The dimensions of the entire mechanism can be determined so that, in this assembled position, the cam 20 exerts a permanent force for clamping or pinching the mounting plate 5 and the multi-conductor cable 8 in order to constitute a rigid attachment of the housing 3 to the rail 1. A certain elasticity of the rear wall 17 and of the front wall 18 easily allows such a pinching to be carried out in order to establish a removable rigid connection of the housing 3 on the rail 1.

Après que l'ensemble constitué par la plaque de montage 5 et le câble multiconducteur 8 est engagé dans la gorge 6, le fait de faire tourner la came 20 dans le sens contraire des aiguilles d'une montre en relevant la manette 22 jusqu'à sa position verticale (jusqu'à la position représentée sur la figure 5) provoque le rapprochement du câble multiconducteur 8 de la paroi arrière 17. Sur la paroi arrière 17, est disposé un élément de contact électrique 26 qui se termine en forme de pointe effilée. Cet élément de contact électrique 26 traverse de part en part la paroi arrière 17 de telle sorte que sa partie en forme de pointe effilée débouche dans la gorge 6. Lors de la manoeuvre de montage, le rapprochement du câble multiconducteur 8 de la paroi 17 a pour conséquence que la pointe effilée de l'élément de contact électrique 26 perce le câble 8 en transperçant sa couche externe isolante et perce également l'isolant d' un des fils conducteurs 27 du câble 8 qui est disposé en regard de l'élément de contact électrique 26. Ceci provoque le contact électrique entre le fil conducteur 27 et l'élément de contact électrique 26. La partie arrière de l'élément de contact électrique 26 est connectée, par l'intermédiaire d'une pièce de raccordement électrique 28, à l'une des bornes électriques 29 du socle de prise de courant 16 qui est monté à l'intérieur de la partie supérieure 14 du boîtier 3. En fait, il est généralement prévu plus d'un élément de contact électrique 26 ; en général il est prévu 2 ou 3 éléments de contact électrique dans un même boîtier 3. En effet, la plupart des prises électriques ou des autres moyens de connexion destinés à établir des contacts électriques par enfichage comportent plus d'un élément conducteur à connecter, en particulier 2 ou 3 éléments conducteurs distincts. Par souci de clarté on a représenté un seul élément de contact électrique 26 mais on peut comprendre aisément que d'autres éléments de contact électriques peuvent être agencés de façon similaire au niveau de la paroi arrière 17 du boîtier 3, tout en étant espacés entre eux d'une distance suffisante pour assurer leur isolement électrique et tout en étant respectivement connectés à des bornes correspondantes de la prise électrique 16 logée dans la partie supérieure 14 du boîtier 3. L'opération de montage du boîtier 3 sur le rail 1 provoque alors la connexion simultanée des différentes bornes de la prise 16 avec les différents fils électriques correspondants du câble multiconducteur 8.After the assembly constituted by the mounting plate 5 and the multi-conductor cable 8 is engaged in the groove 6, the fact of rotating the cam 20 anticlockwise by raising the lever 22 until its vertical position (up to the position shown in FIG. 5) brings the multiconductor cable 8 closer to the rear wall 17. On the rear wall 17, an electrical contact element 26 is arranged which ends in the shape of a tapered point . This electrical contact element 26 passes right through the rear wall 17 so that its part in the shape of a tapered point opens into the groove 6. During the mounting operation, the bringing together of the multiconductor cable 8 from the wall 17 has as a consequence that the tapered tip of the electrical contact element 26 pierces the cable 8 by piercing its insulating outer layer and also pierces the insulation of one of the conductive wires 27 of the cable 8 which is arranged opposite the element of electrical contact 26. This causes electrical contact between the conductive wire 27 and the element of electrical contact 26. The rear part of the electrical contact element 26 is connected, by means of an electrical connection part 28, to one of the electrical terminals 29 of the socket outlet 16 which is mounted at the interior of the upper part 14 of the housing 3. In fact, more than one electrical contact element 26 is generally provided; in general, 2 or 3 electrical contact elements are provided in the same housing 3. In fact, most electrical sockets or other connection means intended for establishing electrical contacts by plug-in comprise more than one conductive element to be connected, in particular 2 or 3 separate conductive elements. For the sake of clarity, a single electrical contact element 26 has been shown, but it can easily be understood that other electrical contact elements can be arranged similarly at the rear wall 17 of the housing 3, while being spaced apart. a sufficient distance to ensure their electrical isolation and while being respectively connected to corresponding terminals of the electrical outlet 16 housed in the upper part 14 of the housing 3. The operation of mounting the housing 3 on the rail 1 then causes the simultaneous connection of the different terminals of the socket 16 with the different corresponding electrical wires of the multi-conductor cable 8.

Sur la figure 4, on distingue la forme de la manette 22 lorsque celle-ci est dans sa position relevée ou verticale. Cette forme particulière donnée à titre d'exemple dans ce mode de réalisation n'est pas indispensable pour le fonctionnement du mécanisme mais elle présente un avantage fonctionnel et esthétique qui va être décrit maintenant. La manette 22 fait corps avec la came 20 et présente, lorsqu'elle est en position verticale (comme représenté sur la figure 4), une forme générale d'un T dont la longueur de la barre horizontale du T correspond à la largeur hors tout du boîtier 3 et dont l'épaisseur de la barre verticale du T correspond à la largeur de la came 20. Pour expliquer cela autrement, on peut dire que la manette 22 présente une forme élargie qui permet à cette manette, lorsqu'elle est en position relevée ou verticale, d'occuper sensiblement tout l'espace qui sépare la partie supérieure 14 du boîtier 3 et sa partie inférieure qui comprend essentiellement deux parties latérales 32, 33 qui font corps avec le reste du boîtier 3 et qui soutiennent les deux extrémités opposées de l' arbre de pivotement 23 qui traverse de part en part la partie inférieure de la manette 2 (qui correspond également à la partie avant de la came 20) afin de constituer l'articulation de la came 20. On voit que dans ces conditions, on peut agencer aisément un boîtier 3 dont la face avant 35 de la partie supérieure 14, la face avant 36 de la manette 22 lorsque celle-ci est relevée ou verticale ainsi que la face avant 37 des parties 32, 33 qui constituent les supports de l'axe d'articulation de la came 20 sont trois faces qui sont de préférence planes et sensiblement dans le même plan, ceci afin de constituer une face avant relativement plane et continue du boîtier 3. Cette disposition est avantageuse du point de vue de son esthétique et de sa protection par rapport aux risques d'introduction de corps étrangers à l'intérieur du mécanisme.In FIG. 4, the shape of the handle 22 can be distinguished when the latter is in its raised or vertical position. This particular form given by way of example in this embodiment is not essential for the operation of the mechanism but it has a functional and aesthetic advantage which will now be described. The handle 22 is integral with the cam 20 and, when it is in the vertical position (as shown in FIG. 4), a general shape of a T whose length of the horizontal bar of the T corresponds to the overall width of the housing 3 and whose thickness of the vertical bar of the T corresponds to the width of the cam 20. To explain this otherwise, we can say that the handle 22 has an enlarged shape which allows this handle, when it is in the raised or vertical position, to occupy substantially all the space which separates the upper part 14 of the housing 3 and its lower part which comprises essentially two lateral parts 32, 33 which are integral with the rest of the housing 3 and which support the two opposite ends of the pivot shaft 23 which passes right through the lower part of the lever 2 (which also corresponds to the part front of the cam 20) in order to constitute the articulation of the cam 20. It can be seen that under these conditions, a housing 3 can easily be arranged, the front face 35 of the upper part 14, the front face 36 of the a lever 22 when the latter is raised or vertical as well as the front face 37 of the parts 32, 33 which constitute the supports of the articulation axis of the cam 20 are three faces which are preferably flat and substantially in the same plan, this in order to constitute a relatively flat and continuous front face of the housing 3. This arrangement is advantageous from the point of view of its aesthetics and of its protection with respect to the risks of introduction of foreign bodies inside the mechanism.

Pour ôter un boîtier 3 du rail 1, il suffit de saisir par les côtés la manette 22 et de l'abaisser (de façon à l'amener dans la position qui est représentée sur la figure 3), puis de pousser vers le mur 10 le boîtier 3 de façon à séparer le câble multiconducteur 8 de la paroi arrière 17 afin de dégager la ou les pointes effilées qui percent le câble 8 et enfin d'extraire vers le haut le boîtier 3. Le câble multiconducteur 8 garde son intégrité et pratiquement toutes ses qualités d'isolation électrique après qu'un boîtier 3 a été monté sur le rail 1 et qu'il a été ensuite ôté du rail 1. En effet, comme cela est connu en soi, la couche externe d'isolation du câble peut se refermer pratiquement complètement après l'enlèvement de la pointe effilée qui l'a transpercée.To remove a box 3 from the rail 1, simply grasp the lever 22 by the sides and lower it (so as to bring it into the position which is shown in FIG. 3), then push towards the wall 10 the housing 3 so as to separate the multi-conductor cable 8 from the rear wall 17 in order to release the tapered point or points which pierce the cable 8 and finally extract the housing 3 upwards. The multiconductor cable 8 retains its integrity and practically all of its qualities of electrical insulation after a housing 3 has been mounted on the rail 1 and it has then been removed from the rail 1 Indeed, as is known per se, the outer insulation layer of the cable can close almost completely after the removal of the tapered tip which has pierced it.

Sur les figures 3 et 5 on distingue en outre une autre partie du mécanisme qui n'est pas indispensable au fonctionnement qui a été décrit précédemment mais qui constitue une variante possible de réalisation ou un perfectionnement de la présente invention. Cette partie complémentaire est constituée essentiellement par une pièce qui est, de façon connue, incluse dans une prise électrique femelle classique, cette pièce constituant un volet obturateur 40. Le volet obturateur 40 (connu en soi) est logé dans la prise électrique 16, est dans une position dans laquelle il masque les bornes de contact de la prise lorsqu'aucune prise mâle n'est enfichée dans la prise et s'escamote lorsque la prise mâle vient s'enficher dans la prise femelle. Selon cette variante de la présente invention, on utilise avantageusement le déplacement du volet obturateur 40 lorsqu'une fiche mâle est engagée dans la prise 16. En effet, il est prévu une tige de commande 41 dont une extrémité est reliée rigidement au volet obturateur 40 et dont l'autre extrémité 42 vient coopérer avec la came 20 de telle sorte que, lorsqu'une prise mâle 43 n'est pas enfichée, la tige de commande 41 libère la came 20 pour que cette came puisse être actionnée manuellement afin de fixer le boîtier 3 sur le rail 1 ou afin de le libérer du rail 1, et lorsque la prise mâle 43 est enfichée dans la prise femelle 16, l'extrémité 42 de la tige de commande 41 verrouille la came 20. Dans sa position verrouillée, la came 20 ne peut pas être actionnée et reste dans la position qui est représentée sur la figure 5. Si, dans cette position, le boîtier 3 n'est pas monté sur un rail 1, ce boîtier 3 ne peut pas y être monté puisqu'il n'est pas possible d'abaisser préalablement la manette 22, et si ce boîtier 3 est déjà monté sur le rail 1, il ne peut pas en être ôté pour la même raison de l'impossibilité d'abaisser la manette 22.Figures 3 and 5 further distinguish another part of the mechanism which is not essential to the operation which has been described above but which constitutes a possible variant of embodiment or an improvement of the present invention. This complementary part consists essentially of a part which is, in known manner, included in a conventional female electrical socket, this part constituting a shutter flap 40. The shutter flap 40 (known per se) is housed in the electrical socket 16, is in a position in which it hides the contact terminals of the socket when no male socket is inserted in the socket and retracts when the male socket is inserted in the female socket. According to this variant of the present invention, the displacement of the shutter 40 is advantageously used when a plug is engaged in the socket 16. In fact, a control rod 41 is provided, one end of which is rigidly connected to the shutter 40 and the other end 42 of which cooperates with the cam 20 so that, when a male connector 43 is not inserted, the control rod 41 releases the cam 20 so that this cam can be actuated manually in order to fix the housing 3 on the rail 1 or in order to release it from the rail 1, and when the male plug 43 is inserted in the female plug 16, the end 42 of the control rod 41 locks the cam 20. In its locked position, cam 20 does cannot be actuated and remains in the position which is shown in FIG. 5. If, in this position, the housing 3 is not mounted on a rail 1, this housing 3 cannot be mounted there since it does not it is not possible to lower the handle 22 beforehand, and if this box 3 is already mounted on the rail 1, it cannot be removed for the same reason of the impossibility of lowering the handle 22.

Sur la figure 6, on a représenté une autre variante de réalisation de la présente invention. Dans cette autre variante, le boîtier 3 ne renferme plus de prise électrique (telle que celle 16 qui est logée dans le boîtier représenté sur les figures 2 à 5) mais ce boîtier 3 supporte uniquement une borne de liaison électrique continue 45. Cette variante peut être utilisée par exemple dans le cas où l'on souhaite connecter un appareil électrique au boîtier 3, de façon inamovible. On rencontre ce type de branchement électrique par exemple pour le branchement des radiateurs électriques dont la puissance est trop forte par rapport à celle qui est permise pour un branchement par prise enfichable. Dans ce cas, le boîtier 3 comporte de préférence en outre un capot ou couvercle 46 qui forme une paroi sensiblement verticale venant masquer à l'avant la partie supérieure 15 du boîtier 3. Le capot 46 améliore l'esthétique du boîtier 3 et isole et protège l'intérieur du boîtier. Les fils électriques du câble 47 débouchent à l'intérieur du boîtier 3 en passant au travers du raccord 45 et chacun de ces fils est connecté à une borne 48 elle-même connectée d'une façon similaire à ce qui a été décrit précédemment par l'intermédiaire d'un élément de connexion 49 à l'un des éléments de contact électrique 26 montés dans la partie inférieure 15 du boîtier 3.In Figure 6, there is shown another alternative embodiment of the present invention. In this other variant, the box 3 no longer contains an electrical outlet (such as that 16 which is housed in the box shown in FIGS. 2 to 5) but this box 3 only supports a continuous electrical connection terminal 45. This variant can be used for example in the case where it is desired to connect an electrical appliance to the housing 3, in an irremovable manner. This type of electrical connection is encountered for example for the connection of electric radiators whose power is too high compared to that which is permitted for connection by plug-in socket. In this case, the housing 3 preferably further comprises a cover or cover 46 which forms a substantially vertical wall which masks at the front the upper part 15 of the housing 3. The cover 46 improves the aesthetics of the housing 3 and insulates and protects the inside of the case. The electrical wires of the cable 47 open into the interior of the housing 3 by passing through the connector 45 and each of these wires is connected to a terminal 48 which is itself connected in a similar manner to what has been described above by the 'via a connection element 49 to one of the electrical contact elements 26 mounted in the lower part 15 of the housing 3.

La variante de réalisation qui est représentée sur la figure 7 montre qu'un tel boîtier 3 peut être monté sur un rail 1 sans que la fonction d'établissement de contacts électriques entre des fils électriques et des bornes d'une prise contenue dans le boîtier 3 ne soit réalisée. En effet, il peut être utile de disposer également sur un rail 1 (muni ou non d'un câble multiconducteur 8) d'un boîtier 2 qui ne comporte pas de prise électrique mais qui permet de supporter un moyen de connexion électrique quelconque (non représenté) utilisant des fils électriques 52 qui proviennent d'un câble 53 qui n'est pas disposé le long du rail 1 mais qui provient par exemple d'une goulotte 11 située sous le rail 1. En effet, certains fils électriques, par exemple des câbles téléphoniques, des fibres optiques ou d'autres connexions électriques spécialisées, ne présentent pas les caractéristiques permettant leur agencement sous la forme du câble multiconducteur 8 qui a été décrit précédemment en relation avec les figures 1 à 6. Dans ce cas, on peut tout de même installer un boîtier 3 similaire au boîtier précédemment décrit, et en particulier on peut utiliser le même mode de fixation mécanique du boîtier 3 sur le rail 1 (c'est-à-dire le mécanisme utilisant la came 20). Dans ce cas, le boîtier 3 peut comporter un capot avant 54 servant à obturer la partie supérieure 14 du boîtier 3 et pouvant éventuellement servir de support pour une prise spéciale, destinée au raccordement des fils conducteurs 52.The variant embodiment which is shown in FIG. 7 shows that such a housing 3 can be mounted on a rail 1 without the function of establishing electrical contacts between electrical wires and terminals of a socket contained in the housing 3 being performed. Indeed, it may be useful to also have on a rail 1 (with or without a multiconductor cable 8) a housing 2 which does not have an electrical outlet but which allows to support any means of electrical connection (not shown) using electrical wires 52 which come from a cable 53 which is not disposed along the rail 1 but which for example comes from a chute 11 located under the rail 1. Indeed, certain electrical wires, for example telephone cables, optical fibers or other specialized electrical connections do not have the characteristics allowing their arrangement in the form of the multiconductor cable 8 which has been described previously in relation to FIGS. 1 to 6. In this case, it is possible to still install a housing 3 similar to the housing described above, and in particular we can use the same mechanical fixing method of the housing 3 on the rail 1 (that is to say the mec anism using cam 20). In this case, the housing 3 may include a front cover 54 used to close off the upper part 14 of the housing 3 and which may possibly serve as a support for a special socket, intended for the connection of the conducting wires 52.

Au travers de tous les exemples de réalisation qui ont été décrits précédemment, on peut remarquer une grande similitude de formes dans les pièces essentielles qui constituent le dispositif de distribution électrique répartie, à savoir le boîtier 3, le rail 1 et le câble multiconducteur 8, le mécanisme de prise de contact par pointe effilée 26 ainsi que le mécanisme de fixation amovible 20. Ces similitudes de formes permettent d'envisager un ensemble de boîtiers 3 qui présentent une esthétique cohérente et qui ne différent que par la nature de la prise électrique qui est incluse dans chaque boîtier 3. On peut par exemple prévoir un boîtier 3 destiné à renfermer une prise femelle d'alimentation électrique ou un socle de prise de courant 220 V, une prise téléphonique ou une prise d'antenne TV et un autre boîtier 3 destiné à supporter un raccord électrique inamovible 45.Through all the exemplary embodiments which have been described above, one can notice a great similarity of shapes in the essential parts which constitute the distributed electrical distribution device, namely the housing 3, the rail 1 and the multiconductor cable 8, the contacting mechanism by tapered tip 26 as well as the removable fixing mechanism 20. These similarities of shapes make it possible to envisage a set of boxes 3 which have a coherent aesthetic and which differ only in the nature of the electrical outlet which is included in each box 3. For example, it is possible to provide a box 3 intended to contain a female electrical supply socket or a base 220 V socket, a telephone socket or a TV antenna socket and another box 3 intended to support a non-removable electrical connection 45.

L'une des particularités de la présente invention réside dans le fait que le dispositif de fixation du boîtier 3 sur le rail 1 comprend un mécanisme qui, hors de son actionnement, permet, en une seule opération (qui consiste simplement à relever la manette 22 de la came 20) d'obtenir la fixation mécanique du boîtier 3 sur le rail 1 et l'établissement simultané des différentes connexions électriques entre des fils électriques contenus dans le câble multiconducteur 8 et les bornes 29 de la prise électrique (ou du raccord fixe 45).One of the features of the present invention resides in the fact that the device for fixing the housing 3 to the rail 1 comprises a mechanism which, outside of its actuation, allows, in a single operation (which consists simply in raising the lever 22 of the cam 20) to obtain the mechanical fixing of the housing 3 on the rail 1 and the simultaneous establishment of the various electrical connections between the electrical wires contained in the multiconductor cable 8 and the terminals 29 of the electrical outlet (or of the fixed connector 45).

Comme on peut le voir sur les figures 2 à 7, l'extrémité inférieure de la paroi avant 18 du boîtier 3 comporte une partie effilée se projetant vers l'avant 50 qui est destinée à venir s'engager dans une encoche 51 ménagée au voisinage du bord avant de l'embase 4 du rail 1. Lors de l'opération qui consiste à relever la manette 22, le boîtier 3 se déplace vers la droite par rapport au rail 1 (sur les figures) et l'extrémité effilée 50 vient s'engager dans l'encoche 51 afin de contribuer à la fixation rigide du boîtier 3 sur le rail 1.As can be seen in Figures 2 to 7, the lower end of the front wall 18 of the housing 3 has a tapered portion projecting forward 50 which is intended to come to engage in a notch 51 formed in the vicinity from the front edge of the base 4 of the rail 1. During the operation which consists in raising the lever 22, the housing 3 moves to the right relative to the rail 1 (in the figures) and the tapered end 50 comes engage in the notch 51 in order to contribute to the rigid fixing of the housing 3 on the rail 1.

Pour compléter le boîtier 3, il est en outre prévu une paroi de fond 55 s'étendant généralement verticalement de façon à constituer un unique volume sensiblement fermé dont la partie supérieure 14 sert à loger la prise électrique et dont la partie inférieure 15 sert à enfermer la partie arrière de l'élément de contact électrique 26 en forme de pointe, à l'arrière de la paroi arrière 17 de la partie inférieure du boîtier, et la connexion électrique 28 de cet élément de contact électrique 26 avec une borne 29 de la prise électrique 16. Le boîtier 3 est ainsi plus rigide et forme une protection efficace pour les éléments qu'il renferme.To complete the housing 3, there is further provided a bottom wall 55 extending generally vertically so as to constitute a single substantially closed volume, the upper part 14 of which serves to house the electrical outlet and the lower part of which 15 is used to enclose the rear part of the tip-shaped electrical contact element 26, behind the rear wall 17 of the lower part of the housing, and the electrical connection 28 of this electrical contact element 26 with a terminal 29 of the electrical outlet 16. The housing 3 is thus more rigid and forms effective protection for the elements it contains.
