Description

La présente invention concerne un bornier étagé comprenant deux pièces support en matériau plastique moulé, dont chacune comporte une pluralité d'embases de support, et une pluralité de barrettes s'étendant parallèlement l'une à l'autre entre les deux pièces support, chaque barrette venant se fixer respectivement sur une embase de chaque pièce support.The present invention relates to a stepped terminal block comprising two support parts made of molded plastic material, each of which comprises a plurality of support bases, and a plurality of bars extending parallel to each other between the two support parts, each bar coming to be fixed respectively on a base of each support piece.

Dans les borniers étagés connus de l'art antérieur, la pièce support est généralement réalisée en une seule pièce. Dans ce cas, la pièce support unique comporte deux parois latérales reliées par un fond, cet ensemble définissant un volume interne de la pièce support. Il est prévu une pluralité d'éléments de fixation ménagés dans le volume interne de la pièce support, respectivement au voisinage de l'une et l'autre des deux parois latérales. Les barrettes sont vissées au niveau de leurs deux extrémités sur deux éléments de fixation correspondants. Un bornier de ce genre présente l'inconvénient que la pièce support n'est adaptée que pour une longueur déterminée des barrettes. Ce bornier présente aussi l'inconvénient que l'assemblage des barrettes sur la pièce support est relativement compliqué, lent et coûteux, parce qu'il nécessite le positionnement précis des barrettes puis leur vissage sur la pièce support.In the known terminal blocks of the prior art, the support part is generally made in one piece. In this case, the single support piece has two side walls connected by a bottom, this assembly defining an internal volume of the support piece. A plurality of fastening elements are provided in the internal volume of the support piece, respectively in the vicinity of one and the other of the two side walls. The bars are screwed at their two ends onto two corresponding fixing elements. A terminal block of this kind has the disadvantage that the support piece is only suitable for a determined length of the bars. This terminal block also has the disadvantage that the assembly of the bars on the support part is relatively complicated, slow and expensive, because it requires the precise positioning of the bars and then their screwing on the support part.

Il existe aussi des borniers étagés dans lesquels la pièce support est en deux parties séparées disposées de part et d'autre des barrettes. Les barrettes sont fixées au niveau de chaque extrémité à l'une et l'autre des deux pièces support de sorte que l'ensemble constitue une structure rigide qui forme le bornier. Cette disposition présente l'avantage de pouvoir utiliser les mêmes pièces support pour des barrettes de différentes longueurs. L'ensemble ainsi assemblé présente cependant l'inconvénient de manquer de rigidité et d'être relativement difficile à assembler parce qu'il est nécessaire de visser chaque extrémité de barrette sur un logement correspondant ménagé sur les pièces support. Dans un tel bornier, pour fixer une barrette sur une pièce support, il faut tout d'abord disposer l'extrémité correspondante de la barrette dans ou sur le logement prévu à cet effet dans la pièce support, puis amener une vis au travers d'un trou ménagé dans une paroi de ce logement et enfin tourner la vis pour obtenir son vissage dans un trou taraudé correspondant de la barrette. Cette opération est relativement délicate parce que l'on risque de faire tomber la vis ou parce qu'il est difficile de positionner correctement la barrette dans le logement de façon à ce que la vis puisse se visser sur la barrette. D'autre part, les barrettes comportent par conséquent au niveau de leurs deux extrémités un trou taraudé spécial qui permet la fixation par vissage sur la pièce support, et de ce fait la barrette ne peut pas être produite simplement à partir d'un profilé de longueur quelconque et, après son découpage à la longueur voulue, il est nécessaire d'usiner ces deux trous taraudés au voisinage des deux extrémités de chaque barrette.There are also stepped terminal blocks in which the support part is in two separate parts arranged on either side of the bars. The bars are fixed at each end to one and the other of the two support parts so that the assembly constitutes a rigid structure which forms the terminal block. This arrangement has the advantage of being able to use the same support parts for bars of different lengths. The assembly thus assembled has the disadvantage of lacking rigidity and of being relatively difficult to assemble because it is necessary to screw each end of the bar onto a housing. correspondent on the support parts. In such a terminal block, to fix a bar on a support piece, you must first place the corresponding end of the bar in or on the housing provided for this purpose in the support piece, then bring a screw through a hole in a wall of this housing and finally turn the screw to obtain its screwing in a corresponding tapped hole in the bar. This operation is relatively delicate because there is a risk of dropping the screw or because it is difficult to correctly position the bar in the housing so that the screw can be screwed onto the bar. On the other hand, the bars therefore have at their two ends a special threaded hole which allows fixing by screwing on the support piece, and therefore the bar can not be produced simply from a profile of any length and, after cutting to the desired length, it is necessary to machine these two tapped holes in the vicinity of the two ends of each bar.

Par ailleurs, dans les borniers connus utilisant deux pièces support séparées, celles-ci ne sont pas conçues de façon identique parce que l'une des pièces présente une paroi latérale extérieure située à gauche des logements destinés à la fixation des barrettes et l'autre pièce support présente une paroi latérale extérieure située à droite des logements destinés à la fixation des barrettes. Les deux pièces support présentent une symétrie par rapport à un plan médian du bornier mais ne sont cependant pas identiques et ne peuvent pas être réalisées à partir du même moule. Une telle conception nécessite par conséquent de produire et de gérer deux catégories différentes de pièces support, à savoir les pièces support droite et les pièces support gauche.Furthermore, in known terminal blocks using two separate support parts, these are not designed in an identical manner because one of the parts has an external lateral wall situated to the left of the housings intended for fixing the bars and the other support piece has an outer side wall located to the right of the housings intended for fixing the bars. The two support parts have a symmetry with respect to a median plane of the terminal block but are however not identical and cannot be produced from the same mold. Such a design therefore requires the production and management of two different categories of support parts, namely the right support parts and the left support parts.

Le document FR-A 2.622.742 fait connaître un bornier individuel formé par le montage d'une barrette conductrice sur une semelle support monobloc en matériau isolant. La semelle allongée présente des pieds élastiques d'encliquetage sur un rail profilé, et des rainures de fixation élastique sur un fer plat. La face de réception de la barrette est agencée en glissière dans laquelle peut être enfilée à coulissement la barrette. Le maintien de la barrette sur la semelle support est assurée à l'une des extrémités par une languette élastique de retenue. Dans les borniers étagés, les différentes barrettes sont positionnées sans leurs semelles isolantes entre les deux pièces supports en forme de flasques.Document FR-A 2.622.742 discloses an individual terminal block formed by the mounting of a conductive bar on a monobloc support sole made of insulating material. The elongated sole has elastic snap-on feet on a profiled rail, and elastic fixing grooves on a flat iron. The receiving face of the bar is arranged in a slide in which the slide can be slid on. Maintaining the bar on the support sole is provided at one end by an elastic retaining tab. In the staged terminal blocks, the various bars are positioned without their insulating soles between the two support parts in the form of flanges.

Un objet de la présente invention consiste à fournir un bornier étagé de conception plus simple et plus économique.An object of the present invention is to provide a stepped terminal block of simpler and more economical design.

Un autre objet de la présente invention consiste à fournir un tel bornier pouvant en outre utiliser des mêmes pièces pour des longueurs de barrettes différentes.Another object of the present invention is to provide such a terminal block which can also use the same parts for different lengths of bars.

L'invention concerne donc un bornier comprenant deux pièces support dont chacune comporte une pluralité d'embases de support et une pluralité de barrettes dont chacune vient se fixer respectivement sur une embase de chaque pièce support.The invention therefore relates to a terminal block comprising two support parts, each of which comprises a plurality of support bases and a plurality of bars, each of which is fixed respectively on a base of each support part.

Selon une caractéristique essentielle, chaque embase comporte, au niveau de sa partie supérieure, un premier élément de verrouillage et en ce que chaque barrette comporte, au niveau de sa partie inférieure, un second élément de verrouillage, lesdits premier et second éléments de verrouillage coopérant pour constituer un verrouillage positif par encliquetage.According to an essential characteristic, each base comprises, at its upper part, a first locking element and in that each bar comprises, at its lower part, a second locking element, said first and second cooperating locking elements to constitute a positive locking by snap-fastening.

Selon un mode de réalisation particulier de l'invention, lesdites deux pièces support sont identiques, chaque pièce support présentant une pluralité d'embases positionnées de sorte qu'en disposant deux pièces support espacées l'une de l'autre et retournées de 180° l'une par rapport à l'autre, les embases respectives des deux pièces support soient situées l'une en face de l'autre afin de permettre la fixation de plusieurs barrettes parallèles entre elles.According to a particular embodiment of the invention, said two support pieces are identical, each support piece having a plurality of bases positioned so that by having two support pieces spaced from one another and turned 180 ° relative to each other, the respective bases of the two support parts are located one opposite the other in order to allow the attachment of several parallel bars between them.

Selon un autre mode de réalisation de l'invention, les premier et second éléments de verrouillage constituent une liaison mécanique du type à coulisseau et glissière, l'embase de la pièce support comportant la glissière de ladite liaison mécanique et la partie inférieure de la barrette comportant le coulisseau de ladite liaison mécanique.According to another embodiment of the invention, the first and second locking elements constitute a mechanical connection of the slide and slide type, the base of the support part comprising the slide of said mechanical connection and the lower part of the bar comprising the slide of said mechanical connection.

En se reportant à la figure 1, on distingue un bornier étagé 1 qui comprend deux pièces support parfaitement identiques 2 et un certain nombre de barrettes 3 montées au niveau de chaque extrémité sur l'une et l'autre des deux pièces support 2. Chaque pièce support 2 comprend plusieurs embases 4 dont la structure et la fonction vont être expliqués en détail par la suite. L'une des embases 4 d'une pièce support 2 est montrée dans la figure 1 de façon agrandie, comme vue au travers d'une loupe. Chaque embase 4 reçoit une extrémité d'une barrette 3, et cette barrette 3 vient se fixer sur l'embase 4. Cette fixation constitue un verrouillage positif par encliquetage, comme cela apparaîtra clairement lors de la description qui va suivre. Les deux pièces support 2 comportent en outre chacune une paroi latérale externe 5. Les embases 4 sont solidaires de la paroi latérale 5, de sorte que chaque pièce support 2 est de préférence réalisée en une seule pièce en matière plastique moulée qui constitue à la fois la paroi latérale 5 et les embases 4. Les deux pièces support 2 qui composent un bornier sont retournées l'une par rapport à l'autre de façon à ce que chaque paroi latérale 5 soit dirigée vers l'extérieur et que les deux parois latérales 5 délimitent ensemble un volume intérieur du bornier. Le bornier peut en outre comporter un capot 6, de préférence en matière plastique transparente, qui vient fermer au moins partiellement le volume intérieur du bornier, en se positionnant au niveau de ses bords latéraux contre des bords des deux parois latérales 5.Referring to Figure 1, there is a stepped terminal block 1 which includes two perfectly identical support parts 2 and a number of bars 3 mounted at each end on one and the other of the two support parts 2. Each support part 2 comprises several bases 4 whose structure and function will be explained in detail below. One of the bases 4 of a support piece 2 is shown in Figure 1 enlarged, as seen through a magnifying glass. Each base 4 receives one end of a strip 3, and this strip 3 is fixed on the base 4. This fixing constitutes a positive locking by snap-fastening, as will become clear during the description which follows. The two support pieces 2 each further comprise an external side wall 5. The bases 4 are integral with the side wall 5, so that each support piece 2 is preferably made in a single piece of molded plastic which constitutes both the side wall 5 and the bases 4. The two support pieces 2 which make up a terminal block are turned over with respect to each other so that each side wall 5 is directed outwards and the two side walls 5 together delimit an interior volume of the terminal block. The terminal block may also include a cover 6, preferably made of transparent plastic, which at least partially closes the internal volume of the terminal block, by positioning itself at its lateral edges against the edges of the two lateral walls 5.

Sur la figure 2, on distingue une partie d'une pièce support 2 du bornier 1. On distingue dans cette vue un certain nombre d'embases 4 reliées à la paroi latérale 5. On remarque aussi que la pièce support 2 comporte en outre une semelle 8 qui sert à la fois de support aux embases 4 et à la paroi latérale 5. La semelle 8 comporte en outre sur sa partie arrière, c'est-à-dire sur sa face inférieure, des rainures profilées 9 de façon à permettre le positionnement de la semelle 8 sur différentes sortes de rails qui peuvent être positionnés horizontalement (par exemple le rail 10) ou verticalement (par exemple les rails 11 et 12).In FIG. 2, there is a part of a support piece 2 of the terminal block 1. In this view, there are a certain number of bases 4 connected to the side wall 5. It is also noted that the support piece 2 also has a sole 8 which serves both as a support for the bases 4 and for the side wall 5. The sole 8 also has, on its rear part, that is to say on its underside, profiled grooves 9 so as to allow the positioning of the sole 8 on different kinds of rails which can be positioned horizontally (for example the rail 10) or vertically (for example the rails 11 and 12).

Bien que l'on distingue la forme et la structure de l'embase 4 sur la figure 2, on se reportera de préférence à la figure 3 pour expliquer en détail la forme et la structure de l'embase 4 et de la barrette 3. Sur la figure 3, on distingue, en section transversale, les contours de la barrette 3 et de l'embase 4. La barrette 3 est représentée successivement dans trois positions afin d'illustrer l'opération de montage ou de démontage de la barrette 3 sur l'embase 4. Un premier contour 3A de la barrette illustre sa position au début de son montage sur l'embase 4, un second contour 3B de la barrette illustre sa position intermédiaire, lors du montage, et un troisième contour 3C illustre la barrette dans sa position complètement montée sur l'embase 4. Lorsque la barrette est ainsi montée complètement sur l'embase 4, on dit qu'elle est fixée sur l'embase 4 de façon à constituer un verrouillage positif, c'est-à-dire que la barrette 3 est fixée dans cette position d'une manière rigide et ne peut pas être désolidarisée de l'embase 4 par une simple traction quelconque mais peut seulement être désolidarisée de l'embase 4 en effectuant manuellement une manoeuvre spécifique de déverrouillage (que l'on expliquera en détail par la suite).Although the shape and structure of the base 4 can be distinguished in FIG. 2, reference will preferably be made to FIG. 3 to explain in detail the shape and structure of the base 4 and of the bar 3. In FIG. 3, there can be seen, in cross section, the contours of the bar 3 and of the base 4. The bar 3 is shown successively in three positions in order to illustrate the assembly or disassembly operation of the bar 3 on the base 4. A first contour 3A of the bar illustrates its position at the start of its mounting on the base 4, a second contour 3B of the bar illustrates its intermediate position , during assembly, and a third contour 3C illustrates the bar in its position completely mounted on the base 4. When the bar is thus completely mounted on the base 4, it is said to be fixed on the base 4 of so as to constitute a positive locking, that is to say that the bar 3 is fixed in this position in a rigid manner and cannot be detached from the base 4 by any simple traction but can only be detached from the base 4 by manually performing a specific unlocking maneuver (which will be explained in detail below).

L'embase 4 comporte au niveau de sa partie supérieure (c'est-à-dire par convention dans sa partie dirigée vers le haut sur la figure 3) des formes spécifiques qui constituent un premier élément de verrouillage. La barrette 3 comporte, au niveau de sa partie inférieure (c'est-à-dire sa partie dirigée vers le bas sur la figure 3) d'autres formes spécifiques qui constituent un second élément de verrouillage. Les premier et second éléments de verrouillage coopèrent pour constituer un verrouillage positif par encliquetage (qui va être décrit en détail ci-après). L'embase 4 présente la forme générale d'une glissière et la partie inférieure de la barrette 3 présente la forme générale d'un coulisseau. L'ensemble coulisseau-glissière constitue le mode de positionnement et de verrouillage de la barrette 3 sur l'embase 4. Ce mode d'accouplement ou de liaison par coulisseau et glissière constitue un mode de réalisation particulier de l'invention, et il pourrait être remplacé par d'autres modes d'assemblage tels que par exemple un mode d'assemblage du type à queue d'aronde. La glissière 19 de l'embase 4 est constituée d'une part d'une partie rigide qui comprend une surface d'appui inférieure 20 plane et horizontale, deux surfaces de guidage 21, 22 parallèles entre elles et verticales et une surface de retenue vers le haut 23 située au voisinage du bord supérieur 24 de la surface de guidage verticale 21. La barrette 3 comporte à sa partie inférieure une base qui a la forme d'un coulisseau 26 qui est adapté pour venir se loger dans la glissière 19 de l'embase 4, c'est-à-dire dans l'espace intérieur 19 délimité par les surfaces 20, 21, 22 et 23. Le coulisseau 26 de la barrette 3 comporte une surface inférieure et deux surfaces latérales qui viennent sensiblement en appui ou à proximité de la surface inférieure 20 et des surfaces latérales verticales 21 et 22 qui forment ensemble la glissière 19 de l'embase 4. Le coulisseau 26 comporte en outre des surfaces latérales arrières (ou supérieures) 28, 29. La surface supérieure 29 vient en appui contre ou à proximité de la surface de retenue vers le haut 23 de l'embase 4. L'autre surface supérieure 28 du coulisseau 26 vient en appui contre ou à proximité d'un élément escamotable de retenue vers le haut 30 qui va être décrit ci-après.The base 4 has at its upper part (that is to say by convention in its part directed upwards in FIG. 3) specific shapes which constitute a first locking element. The bar 3 has, at its lower part (that is to say its part directed downwards in FIG. 3) other specific shapes which constitute a second locking element. The first and second locking elements cooperate to form a positive locking by snap-fastening (which will be described in detail below). The base 4 has the general shape of a slide and the lower part of the bar 3 has the general shape of a slide. The slider-slide assembly constitutes the mode of positioning and locking of the bar 3 on the base 4. This mode of coupling or of connection by slider and slide constitutes a particular embodiment of the invention, and it could be replaced by other assembly methods such as for example an assembly mode of the dovetail type. The slide 19 of the base 4 consists on the one hand of a rigid part which comprises a lower support surface 20 which is flat and horizontal, two guide surfaces 21, 22 parallel to each other and vertical and a retaining surface towards the top 23 located in the vicinity of the upper edge 24 of the surface of vertical guide 21. The bar 3 has at its lower part a base which has the shape of a slide 26 which is adapted to be housed in the slide 19 of the base 4, that is to say in the internal space 19 delimited by the surfaces 20, 21, 22 and 23. The slide 26 of the bar 3 has a lower surface and two lateral surfaces which come into substantial abutment or near the lower surface 20 and the vertical lateral surfaces 21 and 22 which together form the slide 19 of the base 4. The slide 26 further comprises rear (or upper) side surfaces 28, 29. The upper surface 29 abuts against or near the retaining surface upwards 23 of the base 4. The other upper surface 28 of the slider 26 bears against or near a retractable upward retaining element 30 which will be described below.

L'élément escamotable de retenue vers le haut 30 forme un cliquet qui peut être escamoté ou désenclenché manuellement. Cet élément escamotable 30 est composé d'une pièce élastique 31 reliée au niveau de sa partie inférieure (non représentée) à l'embase 4 et d'une butée 32 qui est tournée vers le bas et qui est destinée à venir en appui sur la surface dirigée vers le haut 28 du coulisseau 26. La butée 32 est montée sur l'extrémité libre de la pièce élastique 30 et forme un crochet ou un cliquet qui vient verrouiller le coulisseau 26 lorsque celui-ci est complètement engagé dans la glissière 19.The retractable upward retaining element 30 forms a pawl which can be retracted or disengaged manually. This retractable element 30 is composed of an elastic piece 31 connected at its lower part (not shown) to the base 4 and a stop 32 which is turned downwards and which is intended to come to bear on the surface directed upwards 28 of the slide 26. The stop 32 is mounted on the free end of the elastic piece 30 and forms a hook or a pawl which locks the slide 26 when the latter is fully engaged in the slide 19.

Pour engager le coulisseau 26 de la barrette 3 dans la glissière 19 de l'embase 4, il faut effectuer un mouvement particulier à la barrette 3 qui est imagé par les trois tracés successifs 3A, 3B et 3C sur la figure 3. Tout d'abord, il convient de disposer la barrette 3 de façon inclinée en engageant un bord latéral 29 du coulisseau 26 sur la surface de retenue vers le haut 23 de la glissière 19. Il convient ensuite de faire pivoter la barrette 3 autour du point de contact entre la surface 29 du coulisseau 26 et la surface 23 de la glissière 19 de façon à ce que la surface inférieure du coulisseau 26 soit déplacée jusqu'à venir en appui sur la surface dirigée vers le haut 20 du fond de la glissière 19 de l'embase 4. La barrette 3 se retrouve alors dans la position de verrouillage représentée par le tracé 3C. La butée 32 de l'élément escamotable 30 présente en outre une surface inclinée 34 qui est agencée de façon à ce que le pivotement de la barrette 3 provoque un glissement d'un bord inférieur 33 du coulisseau 26 sur la surface inclinée 34 afin de déplacer vers l'extérieur l'élément escamotable 30 qui revient ensuite en position de verrouillage lorsque le coulisseau 26 est complètement engagé dans la glissière 19. Dans cette position, la butée 32 revient à proximité ou en appui sur la surface arrière 28 du coulisseau 26 afin de verrouiller de façon positive la barrette 3 sur l'embase 4. Le déverrouillage de la barrette 3 peut être obtenu uniquement en actionnant manuellement l'élément escamotable 30 de façon à le déplacer vers l'extérieur afin de libérer la butée 32 du coulisseau 26 pour permettre son dégagement par un pivotement en sens inverse de la barrette 3 autour du point de contact entre la surface 29 du coulisseau 26 et la surface 23 de la glissière 19. Le déplacement vers l'extérieur de l'élément escamotable peut s'effectuer manuellement en utilisant par exemple un tournevis ou un autre outil semblable qui permet de provoquer le fléchissement de la partie élastique 31 de l'élément escamotable 30.To engage the slide 26 of the bar 3 in the slide 19 of the base 4, it is necessary to make a particular movement with the bar 3 which is imaged by the three successive traces 3A, 3B and 3C in FIG. first, it is necessary to arrange the bar 3 in an inclined manner by engaging a lateral edge 29 of the slide 26 on the upward retaining surface 23 of the slide 19. It is then necessary to pivot the bar 3 around the point of contact between the surface 29 of the slide 26 and the surface 23 of the slide 19 so that the lower surface of the slide 26 is moved until it comes to bear on the surface directed upwards 20 from the bottom of the slide 19 of the base 4. The bar 3 is then found in the locking position represented by the line 3C. The stop 32 of the retractable element 30 also has an inclined surface 34 which is arranged so that the pivoting of the bar 3 causes a sliding of a lower edge 33 of the slide 26 on the inclined surface 34 in order to move outwardly the retractable element 30 which then returns to the locked position when the slide 26 is fully engaged in the slide 19. In this position, the stop 32 returns close to or in abutment on the rear surface 28 of the slide 26 so to positively lock the bar 3 on the base 4. Unlocking the bar 3 can only be obtained by manually actuating the retractable element 30 so as to move it outwards in order to release the stop 32 from the slide 26 to allow its release by a pivoting in the opposite direction of the bar 3 around the point of contact between the surface 29 of the slide 26 and the surface 23 of the slide re 19. The outward movement of the retractable element can be carried out manually using, for example, a screwdriver or another similar tool which makes it possible to cause the elastic part 31 of the retractable element 30 to flex.

Afin d'obtenir également un verrouillage positif de la barrette 3 sur l'embase 4 dans le sens longitudinal de la barrette, le coulisseau 26 comporte en outre un évidement 35 ménagé dans la surface d'appui inférieure du coulisseau 26 et la glissière 19 comporte en outre une protubérance 36 ménagée sur la surface inférieure 20. La protubérance 36 est destinée à venir s'emboîter dans l'évidement 35 lorsque le coulisseau 26 de la barrette 3 vient s'engager complètement dans la glissière 19 de l'embase 4. Ceci permet d'obtenir une fixation complète de la barrette 3 sur l'embase 4. En particulier, un effort de traction sur les deux pièces support 2 d'un bornier assemblé, cet effort de traction visant à écarter les deux pièces support 2, ne peut pas provoquer le désassemblage du bornier parce que toutes les barrettes 3 relient de façon rigide les deux pièces support 2. Par conséquent, l'ensemble constitué par deux pièces support 2 et par un certain nombre de barrettes 3 verrouillées au niveau de chacune de leurs extrémités sur les deux pièces support 2 constitue un ensemble rigide qui peut être facilement stocké, transporté et monté dans une installation électrique.In order also to obtain positive locking of the bar 3 on the base 4 in the longitudinal direction of the bar, the slide 26 further comprises a recess 35 formed in the lower bearing surface of the slide 26 and the slide 19 comprises in addition, a protuberance 36 formed on the lower surface 20. The protuberance 36 is intended to fit into the recess 35 when the slide 26 of the bar 3 engages completely in the slide 19 of the base 4. This makes it possible to obtain a complete fixing of the bar 3 on the base 4. In particular, a tensile force on the two support parts 2 of an assembled terminal block, this tensile force aiming to separate the two support parts 2, cannot cause the terminal block to be disassembled because all bars 3 rigidly connect the two support parts 2. Consequently, the assembly constituted by two support parts 2 and by a certain number of bars 3 locked at each of their ends on the two support parts 2 constitutes a rigid assembly which can be easily stored, transported and mounted in an electrical installation.

Comme cela est représenté sur la figure 4, on peut utiliser un tel bornier en association avec des dispositifs électriques du type contacteur ou disjoncteur 40. Les dispositifs électriques 40 peuvent être fixés latéralement contre la paroi externe 5 du bornier 1 en utilisant des éléments de fixation adaptés, par exemple clips ou cavaliers 41. On peut ainsi regrouper un certain nombre de dispositifs électriques 40 reliés les uns aux autres, et cet ensemble peut être fixé latéralement sur un bornier 1. On peut en outre associer à l'ensemble des dispositifs électriques 40 une pièce 42 qui permet de cacher les fils électriques 43 qui relient l'ensemble des dispositifs électriques 40 et le bornier 1 et qui peut en outre comporter des éléments en protubérance 44 destinés à venir s'emboîter dans les trous de vissage 45. Un tel cache 42 permet alors de protéger complètement l'ensemble des dispositifs électriques 40 et le bornier 1 afin d'éviter tout contact possible avec une pièce métallique sous tension telle que les fils 43 ou les vis de serrage contenues dans les trous 45.As shown in FIG. 4, such a terminal block can be used in combination with electrical devices of the contactor or circuit breaker type 40. The electrical devices 40 can be fixed laterally against the external wall 5 of the terminal block 1 by using fastening elements suitable, for example clips or jumpers 41. It is thus possible to group together a certain number of electrical devices 40 connected to one another, and this assembly can be fixed laterally on a terminal block 1. It is also possible to associate with all of the electrical devices 40 a part 42 which makes it possible to hide the electrical wires 43 which connect all of the electrical devices 40 and the terminal block 1 and which may also include protruding elements 44 intended to come to fit into the screw holes 45. A such cover 42 then makes it possible to completely protect all of the electrical devices 40 and the terminal block 1 in order to avoid any possible contact. the with a metal part under tension such as the wires 43 or the clamping screws contained in the holes 45.

Comme cela est représenté sur la figure 5, le bornier 1 selon l'invention peut être agencé de façon à laisser des passages latéraux 48 entre une extrémité 3F des barrettes 3 et une paroi latérale 5A d'une pièce support 2. Cela permet un passage facile d'un ou plusieurs fils électriques 49 afin d'établir une connexion électrique entre un tel fil et une barrette arrière. On voit sur cette figure 5 que des embases 4A proches d'une paroi latérale 5A correspondent, sur l'autre pièce support opposée à d'autres embases 4B qui sont éloignées de la paroi latérale 5B correspondante, afin de ménager cet espace 48 et cela, tout en concevant deux pièces support 2 parfaitement identiques. Il est en outre possible de faire passer certains fils électriques 50 en-dessus ou en-dessous d'une barrette. Cela est rendu tout particulièrement facile du fait que les deux pièces support 2 sont écartées l'une de l'autre et laissent entre elles un espace complètement libre 51 traversé seulement par les barrettes 3.As shown in FIG. 5, the terminal block 1 according to the invention can be arranged so as to leave lateral passages 48 between one end 3F of the bars 3 and a side wall 5A of a support piece 2. This allows passage easy one or more electrical wires 49 in order to establish an electrical connection between such a wire and a rear strip. It can be seen in this FIG. 5 that bases 4A close to a side wall 5A correspond, on the other support piece opposite to other bases 4B which are distant from the corresponding side wall 5B, in order to provide this space 48 and that , while designing two perfectly identical support parts 2. It is also possible to pass certain electrical wires 50 above or below a strip. This is made particularly easy by the fact that the two support parts 2 are spaced from one another and leave between them a completely free space 51 crossed only by the bars 3.

En se reportant à la figure 6, on distingue un plot rapporté 55 qui constitue une variante de réalisation de l'invention. Le plot 55 a la particularité de comporter au niveau de sa partie inférieure un élément de fixation semblable à celui qui est ménagé dans la partie inférieure des barrettes 3, comme cela a été décrit précédemment. Ce plot 55 peut par conséquent être monté sur une embase quelconque 4 de la même façon qu'est montée une barrette 3 sur une embase 4. Ce plot 55 comporte en outre un trou de passage 56 qui présente à la fois une section carrée permettant d'y enfiler une barrette classique 57 de section carrée et une section rectangulaire permettant d'enfiler un fer plat 58. Par conséquent, on peut constituer aussi un bornier selon l'invention en disposant deux pièces support 2 et en montant soit des fers plats 56 soit des barrettes classiques 57 sur les plots 55, puis en montant les plots 55 sur les embases 4 des pièces support 2. Ceci permet d'utiliser aussi les pièces support 2 selon l'invention avec des barrettes classiques 57 ou des fers plats 58.Referring to Figure 6, there is an added pad 55 which constitutes an alternative embodiment of the invention. The stud 55 has the particularity of comprising at its lower part a fixing element similar to that which is formed in the lower part of the bars 3, as has been described above. This stud 55 can therefore be mounted on any base 4 in the same way as a bar 3 is mounted on a base 4. This stud 55 also has a through hole 56 which has both a square section allowing 'put on a conventional bar 57 of square section and a rectangular section for threading a flat iron 58. Consequently, one can also constitute a terminal block according to the invention by having two support pieces 2 and mounting either flat irons 56 either conventional bars 57 on the pads 55, then mounting the pads 55 on the bases 4 of the support pieces 2. This also makes it possible to use the support pieces 2 according to the invention with conventional bars 57 or flat bars 58.

Comme cela est représenté sur les figures 7, 8 et 9, un bornier 1 selon l'invention peut comporter au niveau des semelles 8 des pièces support 2 diverses rainures ou autres surfaces d'appui et de guidage (non représentées) permettant de monter le bornier soit à cheval entre deux rails 10 (figure 7) soit verticalement à cheval sur un seul rail 10 (figure 8) soit horizontalement à cheval sur un seul rail 10 (figure 9).As shown in FIGS. 7, 8 and 9, a terminal block 1 according to the invention may comprise, at the level of the soles 8, support parts 2 various grooves or other bearing and guide surfaces (not shown) making it possible to mount the terminal block either straddling two rails 10 (Figure 7) or vertically straddling a single rail 10 (Figure 8) or horizontally straddling a single rail 10 (Figure 9).

De préférence, la pièce support 2 est constituée d'une seule pièce en matière plastique moulée qui comporte à la fois la semelle 8, la paroi latérale 5, les embases 4 ainsi que toutes les parties qui constituent les premiers éléments de verrouillage.Preferably, the support part 2 consists of a single piece of molded plastic which includes both the sole 8, the side wall 5, the bases 4 and all the parts which constitute the first locking elements.

On peut remarquer que, pour que deux pièces support 2 identiques forment un bornier dont les barrettes 3 sont parallèles entre elles, il est nécessaire que les embases 4 d'une pièce support 2 soient réparties de façon équidistante et opposée, deux à deux, par rapport à un plan fictif (plan 60 sur la figure 5) médian et perpendiculaire à la paroi latérale 5 de la pièce support 2.It can be noted that, in order for two identical support pieces 2 to form a terminal block, the bars 3 of which are parallel to each other, it is necessary that the bases 4 of a support piece 2 are distributed equidistantly and opposite, two by two, by relative to a fictitious plane (plane 60 in FIG. 5) median and perpendicular to the side wall 5 of the support part 2.
