Description

L'invention concerne un collecteur électrique destiné notamment à être monté dans une armoire ou un coffret électrique et comprenant une barre conductrice comprenant une partie aplatie, au moins un organe de connexion électrique monté sur ladite barre et comportant au moins un moyen de connexion, chacun de ces moyens étant destiné à permettre la raccordement électrique d'un câble ou analogue à ladite barre, l'opération de raccordement précité étant réalisé au moyen d'un outil approprié, ainsi qu'un bloc de connexion adapté à un tel collecteur.
On connaít un collecteur de terre constitué par une barre en laiton comportant un bloc de connexion monobloc avec ladite barre, ledit bloc comportant un certain nombre de moyens de connexions du type à vis. Or, dans ce type de collecteur, l'orientation des points de raccordement est figée dans une seule direction perpendiculaire au plan de fixation de la barre, d'où il peut résulter une certaine incommodité pendant l'opération de raccordement. En outre, le nombre de points de raccordement et la section des câbles à raccorder sont fixes, et le mode de connexion à vis engendre un temps de connexion relativement long. On connaít également un autre type de collecteur de terre constitué par une barre en cuivre sur laquelle sont fixés une multitude de petits cavaliers en cuivre constituant des bornes à vis pour le raccordement des câbles. Les inconvénients de ce type de système tiennent principalement en ce que l'ensemble n'a pas une résistance mécanique suffisante pour résister aux efforts nécessaires pour le raccordement des câbles, d'où il résulte des déformations en flexion de la barre. D'autre part, comme dans le système décrit précédemment, l'orientation des points de raccordement est figée dans une seule direction perpendiculaire au plan de fixation de la barre; ce système ne permet pas le raccordement de câbles de sections différentes ; le nombre de points de raccordement est fixe; et le temps de connexion des câbles est particulièrement long.
La présente invention résout ces problèmes et propose un collecteur électrique de conception simple, présentant une très bonne résistance mécanique aux efforts nécessaires pour le raccordement des câbles, de grandes possibilités d'adaptation par rapport à la position des câbles, et avec lequel l'opération de raccordement est facilitée. La présente invention a encore pour objet un bloc de connexion destiné notamment à constituer un élément constitutif dudit collecteur.The invention relates to an electrical collector intended in particular to be mounted in an electrical cabinet or cabinet and comprising a conductive bar comprising a flattened part, at least one electrical connection member mounted on said bar and comprising at least one connection means, each of these means being intended to allow the electrical connection of a cable or the like to said bar, the aforementioned connection operation being carried out by means of an appropriate tool, as well as a connection block adapted to such a collector.
There is a known earth collector consisting of a brass bar comprising a one-piece connection block with said bar, said block comprising a number of screw type connection means. However, in this type of collector, the orientation of the connection points is fixed in a single direction perpendicular to the fixing plane of the bar, from which there may result a certain inconvenience during the connection operation. In addition, the number of connection points and the section of the cables to be connected are fixed, and the screw connection mode generates a relatively long connection time. We also know another type of earth collector consisting of a copper bar on which are fixed a multitude of small copper jumpers constituting screw terminals for connecting cables. The drawbacks of this type of system are mainly due to the fact that the assembly does not have sufficient mechanical strength to withstand the forces necessary for connecting the cables, from which it results in bending deformations of the bar. On the other hand, as in the system described above, the orientation of the connection points is fixed in one direction perpendicular to the plane of attachment of the bar; this system does not allow the connection of cables of different sections; the number of connection points is fixed; and the cable connection time is particularly long.
The present invention solves these problems and proposes an electrical collector of simple design, having very good mechanical resistance to the forces necessary for the connection of the cables, great possibilities of adaptation with respect to the position of the cables, and with which the operation connection is made easier. The present invention also relates to a connection block intended in particular to constitute an element constituting said collector.

A cet effet, la présente invention a pour objet un collecteur du genre précédemment mentionné, ce collecteur étant caractérisé en ce que le, l'un au moins ou chaque organe de connexion est orienté par rapport au plan de ladite barre de manière que la direction de la résultante des efforts exercés sur le collecteur par l'outil précité pendant l'opération de raccordement soit sensiblement parallèle au plan de ladite barre.To this end, the present invention relates to a collector of the kind previously mentioned, this collector being characterized in that the, at least one or each member of connection is oriented relative to the plane of said bar so that the direction of the resulting from the forces exerted on the collector by the aforementioned tool during the operation of connection is substantially parallel to the plane of said bar.

Selon une réalisation particulière, cette barre comprend une première partie destinée à recevoir les organes de connexion précités et une seconde partie comprenant au moins une partie de fixation de la barre dans l'armoire ou le coffret précité, et la (les) partie(s) de fixation est (sont) située(s) dans un plan dit plan de fixation, lequel plan est décalé angulairement par rapport au plan contenant la première partie de la barre, dit plan de la barre.According to a particular embodiment, this bar comprises a first part intended for receive the aforementioned connection members and a second part comprising at least one part for fixing the bar in the aforementioned cabinet or box, and the part (s) of attachment is (are) located in a plane called the attachment plane, which plane is offset angularly relative to the plane containing the first part of the bar, called the plane of the closed off.

Selon une autre caractéristique, le bloc comporte en outre des moyens d'extraction du bloc de la barre, ces moyens étant agencés de manière que la direction de la résultante des efforts exercés sur le collecteur pendant l'opération d'extraction, soit sensiblement parallèle au plan de la barre.According to another characteristic, the block also comprises means for extracting the block of the bar, these means being arranged so that the direction of the resultant of the forces exerted on the collector during the extraction operation, ie substantially parallel to the plane of the bar.

Avantageusement, ces moyens d'extraction comprennent au moins une encoche réalisée dans le(s)dit(s) bloc(s), la(les) dite(s) encoche(s) étant destinée(s) à coopérer avec la pointe d'un tournevis.Advantageously, these extraction means comprise at least one notch made in the said block (s), the said notch (s) being intended to cooperate with the tip with a screwdriver.

Selon une caractéristique particulière, les organes de connexion comprennent des modules, lesdits modules comportant l'un par rapport à l'autre, un nombre de moyens de connexion égal ou différent et/ou étant adaptés à des sections de câbles égales ou différentes.According to a particular characteristic, the connection members comprise modules, said modules comprising, relative to each other, a number of connection means equal or different and / or being adapted to equal or different cable sections.

L'invention a aussi pour objet un bloc de connexion comportant un certain nombre de moyens de connexions pour le raccordement d'un câble à une barre aplatie et une rainure apte à recevoir à coulissement ladite barre aplatie, la rainure étant agencée par rapport au bloc de manière que la direction de la résultante des efforts exercés sur l'ensemble constitué par l'organe de connexion et la barre lors de l'opération de raccordement du câble au bloc soit parallèle au plan de ladite rainure ou de la barre.The invention also relates to a connection block comprising a certain number of connection means for connecting a cable to a flattened bar and a groove capable of slidingly receiving said flattened bar, the groove being arranged relative to the block so that the direction of the resultant of the forces exerted on the whole consisting of the connection member and the bar during the cable connection operation to the block is parallel to the plane of said groove or of the bar.

L'invention a encore pour objet un bloc de connexion adapté de manière à pouvoir être utilisé comme élément constitutif d'un collecteur comprenant les caractéristiques précédemment mentionnées prises seules ou en combinaison.The invention also relates to a connection block adapted so that it can be used as a component of a collector comprising the characteristics previously mentioned taken alone or in combination.

Chaque moyen de connexion 7 comporte une pince à ressort 8 (fig.9) et deux orifices 9,10 destinés pour l'un 9, à recevoir un câble 11, et pour l'autre 10, à permettre l'introduction d'un tournevis 12 pour actionner la pince 8 de manière à permettre l'introduction du câble 11 dans l'orifice 9, lequel est retenu par la pince 8 après le retrait du tournevis 12.
Conformément à l'invention, et comme illustré sur les figures 8 et 9, les blocs de connexion 3 sont orientés par rapport au plan P de la partie intermédiaire 6 de la barre 1, de telle façon que la direction R de la résultante des efforts exercés sur le collecteur C pendant l'opération de raccordement soit sensiblement parallèle au plan P de la partie intermédiaire 6 de la barre 1. On voit en effet sur ces figures, que les efforts appliqués sur le collecteur C par la pointe du tournevis 12 vérifient cette caractéristique de l'invention.
Comme on le voit sur les figures 1 et 3 à 6, les blocs de connexion 3 comprennent des moyens de fixation 13 par encliquetage desdits blocs 3 sur la barre 1, ces moyens comprenant une rainure 13 s'étendant d'un côté à l'autre des blocs 3 et apte à recevoir la barre 1 à coulissement de manière à retenir les blocs 3 sur la barre 1.
On voit également sur ces figures, que les blocs 3 comportent en outre des moyens 14 destinés à permettre l'extraction des blocs 3 de la barre 1. Ces moyens comprennent une encoche 14 prévue sur la face externe des blocs et s'étendant d'un côté à l'autre des blocs, dans un plan sensiblement parallèle au plan de la partie intermédiaire 6 de la barre 1 ou au plan de la rainure 13 prévue dans le bloc 3.
L'opération de montage du collecteur C dans l'armoire A et de raccordement des câbles 11 à la barre 1 va être décrite brièvement dans ce qui suit en référence aux figures.
Les blocs de raccordement 3 sont tout d'abord fixés sur la partie intermédiaire 6 de la barre 1 en cuivre équipée de sa borne à vis 2, par introduction (ou encliquetage) de la dite barre 1 dans la rainure 13 des blocs 3.
On notera que le nombre et le type de blocs utilisé variera en fonction du type de raccordement à effectuer. Les figures 11 à 15 illustrent ainsi différents agencements de blocs adaptés au raccordement de câbles de grande ou de petite section. Une fois les blocs 3 fixés sur la barre 1, l'ensemble est fixé sur des supports 15 prévus dans l'armoire A (figure 7) par l'intermédiaire des parties de fixations 4,5 de la barre 1.
Comme on le voit sur les figures 16 à 19, et comme ceci sera expliqué dans ce qui suit, les blocs 3 peuvent être orientés suivant huit positions différentes. En effet, un même bloc 3 peut être introduit par le haut (figs.16,17) ou par le bas (figs.18,19) de la barre 1. En outre, la barre 1 elle-même peut prendre deux positions différentes (figs16,19) et (figs 17,18). En effet, les figures 17 et 18 représentent la barre 1 dans une position inversée par rapport à la position de la barre 1 représentée sur les figures 16 et 19, c'est à dire que la barre, d'une position à l'autre a subi une inversion de position par rapport à un plan perpendiculaire à ladite barre. On voit ainsi, par exemple, que le bloc de raccordement 3 se trouve dans la position orientée vers le haut et la gauche sur les figure 16 et 20, orientée vers le haut et la droite sur les figures 17 et 21, orientée vers le bas et la gauche sur les figures 18 et 22 et orientée vers le bas et la droite sur les figures 19 et 23. Enfin, pour une même position de la barre 1, et un même sens de montage du bloc 3, par le haut ou par le bas de la barre 1, ce bloc 3 peut encore prendre deux positions différentes inversées selon que les moyens de connexion 7 se trouvent d'un côté ou de l'autre de la barre 1 comme ceci est le cas pour les blocs 3a,3d ou 3b,3c sur la figure 17, ceci afin de permettre un meilleur accès aux câbles par rapport au tournevis. Il en résulte qu'un même bloc peut prendre huit positions différentes.
Compte tenu de cette possibilité d'orienter les blocs de raccordement, le collecteur C peut être placé dans l'armoire A à tous les niveaux et dans toutes les positions de manière à s'adapter à l'arrivée et au raccordement des câbles, comme on le voit sur la figure 7. Ainsi, en se reportant à cette figure, on voit que le collecteur C peut être placé en position verticale 16,17,18, en position horizontale 19,20,21,22, à l'extrémité 18 d'une rangée d'appareils 23, directement sur le fond de l'armoire 21,22 et juste en dessous 20 d'une rangée d'appareils 23, verticalement 17 sur toute la largeur de l'armoire A sur des traverses 24, dans une gaine à câble suivant sa largeur 22 ou bien parallèlement 16 au flux de câbles.
Lorsque les collecteurs C sont fixés dans l'armoire A, le raccordement des câbles 11 s'effectue en introduisant l'extrémité desdits câbles 11 dans les orifices 9 après avoir introduit la pointe du tournevis 12 dans le second orifice 10, cette introduction de la pointe du tournevis 12 à l'encontre de la force d'une pièce élastique appartenant à la pince 8 ayant pour effet de libérer l'ouverture du premier orifice 9 pour permettre l'accès aux câbles. Pendant cette opération de raccordement, et comme on le voit sur les figures 8 et 9, l'angle β d'action du tournevis 12 par rapport au plan de fixation Q correspond à l'angle α d'inclinaison de la barre 1 par rapport à ce même plan de fixation Q. Ainsi, pendant cette opération, la direction R de la résultante des efforts exercés sur le collecteur C est parallèle au plan P de la barre (partie intermédiaire de la barre). L'ensemble comprenant la barre 1 et le bloc 3 concerné présente donc une très bonne résistance mécanique en flexion pour résister aux efforts nécessaires pour le raccordement des câbles. On voit également sur la figure 9 que cet angle d'action du tournevis 12, d'environ 45°, est particulièrement adapté pour faciliter l'accès aux câbles 11 dans l'armoire électrique. En outre, l'action du tournevis n'est pas entravée par la présence des câbles qui se trouvent en dessous du tournevis. Il en résulte que l'opération de raccordement est facilitée ainsi que la lecture des schémas et le rajout ou le retrait de câbles en cas d'évolution du câblage.
En se reportant à la figure 10, on voit que l'opération de retrait d'un bloc 3 s'effectue en utilisant le même tournevis 12, celui-ci ayant la même orientation angulaire. Pour ce faire, la pointe du tournevis 12 est introduite dans les encoches 14 prévues à cet effet dans le bloc 3 et une traction est exercée sur le bloc 3 à l'aide du tournevis 12 jusqu'à ce que la barre 1 soit désengagée de la rainure 13 du bloc 3. Lors de cette opération, la direction de la résultante S des efforts exercés sur le collecteur C est, là encore, parallèle au plan P de la barre 1 (partie intermédiaire), d'où il résulte que les risques de flexion de la barre 1 pendant cette opération sont considérablement diminués.In FIG. 1, there is seen an earth collector C according to the invention intended to be placed in an electrical cabinet A, as illustrated in FIG. 7, in order to allow the connection to earth of the various devices, by occurrence of circuit breakers D, placed in this cabinet A.
This collector C is constituted in FIG. 1 by a copper bar 1 on which are fixed a screw terminal 2 and four connection blocks 3, respectively three connection blocks 3a suitable for the connection of cables of small section and a connection block 3b suitable for connecting large section cables. The screw terminal 2, made of folded sheet, is intended to establish an equipotentiality between the copper bar 1 and the earth, while the connection blocks 3 are intended to electrically connect cables coming from the devices to the barrel. The bar 1 is composed of a first part, made up of two fixing parts 4,5 situated respectively at the two ends of the bar 1, and of a second part 6, called intermediate, intended to receive the connection blocks 3. The plane P containing the intermediate part 6 (or plane of the bar) forms with the plane Q of the fixing parts, or fixing plane, an angle α (fig. 9) of about 45 °, this angular offset having been achieved by twisting the bar 1.
Each connection block 3 comprises a certain number of connection means 7, these being of the quick connection type. Each connection means 7 comprises a spring clip 8 (fig. 9) and two orifices 9, 10 intended for one 9, to receive a cable 11, and for the other 10, to allow the introduction of a screwdriver 12 to actuate the clamp 8 so as to allow the introduction of the cable 11 into the orifice 9, which is retained by the clamp 8 after the removal of the screwdriver 12.
According to the invention, and as illustrated in FIGS. 8 and 9, the connection blocks 3 are oriented relative to the plane P of the intermediate part 6 of the bar 1, so that the direction R of the result of the forces exerted on the collector C during the connection operation is substantially parallel to the plane P of the intermediate part 6 of the bar 1. It can be seen in these figures that the forces applied to the collector C by the tip of the screwdriver 12 verify this feature of the invention.
As can be seen in FIGS. 1 and 3 to 6, the connection blocks 3 comprise fixing means 13 by snap-fastening of said blocks 3 on the bar 1, these means comprising a groove 13 extending from one side to the other of the blocks 3 and capable of receiving the sliding bar 1 so as to retain the blocks 3 on the bar 1.
It can also be seen in these figures, that the blocks 3 further comprise means 14 intended to allow the extraction of the blocks 3 from the bar 1. These means comprise a notch 14 provided on the external face of the blocks and extending from side to side of the blocks, in a plane substantially parallel to the plane of the intermediate part 6 of the bar 1 or to the plane of the groove 13 provided in the block 3.
The operation of mounting the manifold C in the cabinet A and connecting the cables 11 to the bar 1 will be described briefly in the following with reference to the figures.
The connection blocks 3 are firstly fixed to the intermediate part 6 of the copper bar 1 fitted with its screw terminal 2, by introduction (or snap-fastening) of the said bar 1 into the groove 13 of the blocks 3.
Note that the number and type of blocks used will vary depending on the type of connection to be made. Figures 11 to 15 thus illustrate different arrangements of blocks suitable for connecting cables of large or small section. Once the blocks 3 are fixed on the bar 1, the assembly is fixed on supports 15 provided in the cabinet A (FIG. 7) by means of the fixing parts 4,5 of the bar 1.
As seen in Figures 16 to 19, and as will be explained below, the blocks 3 can be oriented in eight different positions. Indeed, the same block 3 can be introduced from the top (figs.16,17) or from the bottom (figs.18,19) of the bar 1. In addition, the bar 1 itself can take two different positions (figs16.19) and (figs 17.18). Indeed, Figures 17 and 18 show the bar 1 in an inverted position relative to the position of the bar 1 shown in Figures 16 and 19, that is to say that the bar, from one position to another has undergone a reversal of position relative to a plane perpendicular to said bar. It can thus be seen, for example, that the connection block 3 is in the position facing upwards and to the left in FIGS. 16 and 20, facing upwards and the right in FIGS. 17 and 21, facing downwards and the left in FIGS. 18 and 22 and oriented downwards and the right in FIGS. 19 and 23. Finally, for the same position of the bar 1, and the same mounting direction of the block 3, from above or from the bottom of the bar 1, this block 3 can also take two different reversed positions depending on whether the connection means 7 are located on one side or the other of the bar 1 as this is the case for the blocks 3a, 3d or 3b, 3c in FIG. 17, this in order to allow better access to the cables relative to the screwdriver. As a result, the same block can take eight different positions.
Given this possibility of orienting the connection blocks, the collector C can be placed in the cabinet A at all levels and in all positions so as to adapt to the arrival and connection of the cables, as we see it in Figure 7. Thus, referring to this figure, we see that the collector C can be placed in a vertical position 16,17,18, in a horizontal position 19,20,21,22, at the end 18 of a row of devices 23, directly on the bottom of the cabinet 21,22 and just below 20 of a row of devices 23, vertically 17 over the entire width of the cabinet A on crosspieces 24 , in a cable sheath along its width 22 or else parallel 16 to the cable flow.
When the collectors C are fixed in the cabinet A, the cables 11 are connected by introducing the end of the said cables 11 into the holes 9 after having introduced the tip of the screwdriver 12 into the second hole 10, this introduction of the tip of the screwdriver 12 against the force of an elastic piece belonging to the clamp 8 having the effect of releasing the opening of the first orifice 9 to allow access to the cables. During this connection operation, and as can be seen in FIGS. 8 and 9, the angle β of action of the screwdriver 12 relative to the fixing plane Q corresponds to the angle α of inclination of the bar 1 relative to to this same fixing plane Q. Thus, during this operation, the direction R of the result of the forces exerted on the collector C is parallel to the plane P of the bar (intermediate part of the bar). The assembly comprising the bar 1 and the block 3 concerned therefore has very good mechanical resistance in bending to resist the forces necessary for connecting the cables. It can also be seen in FIG. 9 that this angle of action of the screwdriver 12, of around 45 °, is particularly suitable for facilitating access to the cables 11 in the electrical cabinet. In addition, the action of the screwdriver is not hampered by the presence of the cables which are located below the screwdriver. As a result, the connection operation is facilitated as well as the reading of the diagrams and the addition or removal of cables in the event of changes in the wiring.
Referring to FIG. 10, it can be seen that the operation of removing a block 3 is carried out using the same screwdriver 12, the latter having the same angular orientation. To do this, the tip of the screwdriver 12 is introduced into the notches 14 provided for this purpose in the block 3 and traction is exerted on the block 3 using the screwdriver 12 until the bar 1 is disengaged from the groove 13 of the block 3. During this operation, the direction of the resultant S of the forces exerted on the collector C is, here again, parallel to the plane P of the bar 1 (intermediate part), whence it follows that the risks of bending of the bar 1 during this operation are considerably reduced.

On a donc réalisé grâce à l'invention un collecteur de conception simple et économique et présentant une résistance mécanique en flexion optimale. Ce collecteur est destiné notamment à être monté dans des coffrets ou armoires électriques et permet un raccordement rapide et modulaire en fonction des différentes sections des câbles et du nombre de câbles nécessaire.
Bien entendu, l'invention n'est pas limitée aux modes de réalisations décrits et illustrés qui n'ont été donnés qu'à titre d'exemple.
C'est ainsi que bien que la réalisation décrite concerne un collecteur de terre, l'invention peut s'appliquer de la même manière à un collecteur de neutre ou à tout autre collecteur de même type destiné au raccordement de câbles.
L'invention comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci sont effectuées suivant son esprit.Thanks to the invention, a collector has therefore been produced which is simple and economical in design and which has optimum mechanical resistance in bending. This collector is intended in particular to be mounted in electrical boxes or cabinets and allows a quick and modular connection according to the different sections of the cables and the number of cables required.
Of course, the invention is not limited to the embodiments described and illustrated which have been given only by way of example.
Thus, although the embodiment described relates to an earth collector, the invention can be applied in the same way to a neutral collector or to any other collector of the same type intended for the connection of cables.
The invention includes all the technical equivalents of the means described and their combinations if these are carried out according to the spirit.
