Description

L'invention concerne un bornier de raccordement électrique de câbles d'alimentation en énergie électrique comprenant au moins un conducteur électrique d'une rigidité mécanique importante, notamment pour l'alimentation de dispositifs utilisateurs, dans lequel un dispositif de raccordement est monté entre les deux extrémités préalablement dénudées des conducteurs.The invention relates to a terminal block for the electrical connection of electrical energy supply cables comprising at least one electrical conductor of high mechanical rigidity, in particular for supplying user devices, in which a connection device is mounted between the two. previously stripped ends of the conductors.

Les borniers connus de ce type présentent l'inconvénient de ne pas permettre un raccordement suffisamment aisé, en particulier lorsqu'il s'agit de câbles de forte section et donc rigide comme dans le domaine de l'éclairage public. Il en résulte que ces dispositifs nécessitent le plus souvent des moyens auxiliaires pour compenser les jeux nécessaires de montage, tels que crochets, plaques auxiliaires, ce qui renchérit leur coût. D'autre part, la grande rigidité des câbles électriques entraîne les difficultés de montage et génère dans le temps des défauts de conductibilité qui résultent le plus souvent des tensions provoquées par les moyens de connexion.Known terminal blocks of this type have the drawback of not allowing a sufficiently easy connection, in particular when cables are of large section and therefore rigid as in the field of public lighting. As a result, these devices most often require auxiliary means to compensate for the necessary mounting clearances, such as hooks, auxiliary plates, which increases their cost. On the other hand, the high rigidity of the electric cables leads to assembly difficulties and generates over time conductivity defects which most often result from the tensions caused by the connection means.

La présente invention a pour but de pallier à ces inconvénients.The present invention aims to overcome these drawbacks.

Pour atteindre ce but, le bornier selon l'invention est caractérisé en ce que chaque dispositif de raccordement comprend au moins deux bornes de raccordement dont chacune est raccordé à une des extrémités du conducteur coupé et qui sont électriquement reliées entre elles par un moyen permettant un déplacement relatif d'une borne par rapport à l'autre.To achieve this aim, the terminal block according to the invention is characterized in that each connection device comprises at least two connection terminals, each of which is connected to one of the ends of the cut conductor and which are electrically connected together by means allowing a relative displacement of a terminal compared to the other.

Selon une caractéristique avantageuse de l'invention, le moyen de liaison électrique des bornes est formé par un câble souple dont chaque extrémité est fixée à une borne.According to an advantageous characteristic of the invention, the means of electrical connection of the terminals is formed by a flexible cable, each end of which is fixed to a terminal.

Selon une autre caractéristique de l'invention, le moyen de liaison électrique des deux bornes est du type à vis de connexion et à trou oblong.According to another characteristic of the invention, the means of electrical connection of the two terminals is of the type with connection screw and oblong hole.

L'invention sera mieux comprise et d'autres buts, caractéristiques détails et avantages de celle-ci apparaîtront plus clairement dans la description explicative qui va suivre faite en référence aux dessins schématiques annexés donnés uniquement à titre d'exemple illustrant plusieurs modes de réalisation de l'invention et dans lesquels.The invention will be better understood and other objects, characteristics, details and advantages thereof will appear more clearly in the explanatory description which follows, given with reference to the appended schematic drawings given solely by way of example illustrating several embodiments of the invention and in which.

La figure 1 est une vue en perspective d'un premier mode de réalisation d'un dispositif bornier selon l'invention.Figure 1 is a perspective view of a first embodiment of a terminal device according to the invention.

La figure 2 est une vue de dessus, avec arrachement, du dispositif bornier selon la figure 1.FIG. 2 is a top view, with parts broken away, of the terminal block device according to FIG. 1.

La figure 3 est une vue en coupe selon la ligne III-III de la figure 2.Figure 3 is a sectional view along line III-III of Figure 2.

La figure 4 est une vue en perspective d'un deuxième mode de réalisation d'un dispositif bornier selon l'invention.Figure 4 is a perspective view of a second embodiment of a terminal device according to the invention.

La figure 5 est une vue schématique d'un troisième mode de réalisation d'un dispositif bornier selon l'invention.Figure 5 is a schematic view of a third embodiment of a terminal device according to the invention.

Comme le montre la figure 1, le bornier qui porte la référence générale 1 est monté entre les conducteurs des câbles A, B, au nombre de quatre, qui sont désignés respectivement par a et b. Le bornier permet d'alimenter en énergie électrique des dispositifs utilisateurs. Des conducteurs c constituent les branchements qui sont prévus à cet fin. Le bornier de raccordement 1 peut être destiné par exemple au raccordement en coupure de câbles de forte section et donc d'une grande rigidité d'un réseau d'alimentation en énergie électrique triphasé. Le bornier selon l'invention est avantageusement utilisable dans le domaine de l'éclairage public en pied de candélabres.As shown in Figure 1, the terminal block which has the general reference 1 is mounted between the conductors of cables A, B, four in number, which are designated respectively by a and b. The terminal block supplies electrical power to user devices. Conductors c constitute the connections which are provided for this purpose. The connection terminal block 1 can be intended for example for the connection of large cross-sectional and therefore very rigid cables to a three-phase electrical power supply network. The terminal block according to the invention is advantageously usable in the field of public lighting at the foot of candelabras.

Dans le mode de réalisation représenté aux figures 1 à 3, le bornier selon l'invention est monté verticalement. Il comprend pour chaque paire de conducteurs a, b un dispositif de raccordement. Les quatre dispositifs sont juxtaposés. Ils présentent la même structure et portent donc la même référence 2. Chaque dispositif de raccordement 2 comprend deux bornes de raccordement 4 et 5 destinées à recevoir respectivement un conducteur a et b des câbles A et B. Les extrémités des conducteurs sont dénudées. Ces bornes 4 et 5 viennent respectivement se loger dans des alvéoles 6 et 7 du corps 8 en un matériau électriquement isolant du bornier. Chaque alvéole 6 offre un espace vertical de positionnement important pour le logement de la borne 4 et chaque alvéole 7 est adapté pour recevoir la borne 5. On constate ainsi que le dispositif bornier comprend une rangée de quatre alvéoles 7 juxtaposées supérieures et une rangée de quatre alvéoles juxtaposées inférieures 6.In the embodiment shown in Figures 1 to 3, the terminal block according to the invention is mounted vertically. It includes for each pair of conductors a, b a connection device. The four devices are juxtaposed. They have the same structure and therefore bear the same reference 2. Each connection device 2 comprises two connection terminals 4 and 5 intended to receive respectively a conductor a and b of cables A and B. The ends of the conductors are stripped. These terminals 4 and 5 come respectively to be housed in cells 6 and 7 of the body 8 made of an electrically insulating material of the terminal block. Each cell 6 offers a large vertical positioning space for housing the terminal 4 and each cell 7 is adapted to receive the terminal 5. It can thus be seen that the terminal device comprises a row of four juxtaposed upper cells 7 and a row of four lower juxtaposed alveoli 6.

Chaque borne 4, 5 est du type canon avec serrage par vis, c'est-à-dire elle est réalisée sous forme d'un corps parallélèpipédique qui comprend un passage rectiligne 10 pour l'introduction de l'extrémité dénudée du conducteur respectif a, b et une vis de fixation 11 du conducteur dans la borne. La vis s'engage dans un trou taraudé approprié pratiqué à partir de la surface extérieure 12 de la borne, qui est dégagé et ainsi accessible dans l'alvéole 6 ou 7. Sur les figures 2 et 3, la borne supérieure 5 présente une plus grande longueur que la borne inférieure 4 pour pouvoir fixer dans son passage 10, axialement aligné avec le conducteur b, le conducteur c d'alimentation d'un dispositif d'utilisation. Ce conducteur c est également fixé dans la borne par une vis 13.Each terminal 4, 5 is of the barrel type with screw tightening, that is to say it is produced in the form of a parallelepipedic body which comprises a rectilinear passage 10 for the introduction of the stripped end of the respective conductor a , b and a screw fixing the conductor 11 in the terminal. The screw engages in a suitable tapped hole made from the outer surface 12 of the terminal, which is released and thus accessible in the cell 6 or 7. In FIGS. 2 and 3, the upper terminal 5 has one more great length that the lower terminal 4 to be able to fix in its passage 10, axially aligned with the conductor b, the conductor c supplying a user device. This conductor c is also fixed in the terminal by a screw 13.

Les deux bornes 4 et 5 sont électriquement reliées par un câble conducteur souple ou une tresse conductrice 15 avantageusement plate dont les extrémités 16 et 17 sont de préférence soudées sur les faces respectives 18 opposées aux faces 12 d'engagement des vis de fixation. Une particularité de l'invention réside dans le fait que l'extrémité 17 du câble 15 est soudée à la borne supérieure 5 de façon à former une boucle 20 qui s'étend vers le haut. Cette boucle permet d'offrir une longueur maximale au câble, en particulier dans l'espace 21 de l'alvéole 7, délimité entre la borne 5 et le fond 22 de l'alvéole. Pour assurer l'assise de la borne 5, l'alvéole 7 comprend des supports latéraux 24, 25 réalisés sous forme d'épaulements situés à un niveau approprié pour l'obtention de l'espace 21 nécessaire pour le logement de la boucle 20 du câble 15. En se référant à la figure 3, on constate que l'entrée du conducteur b de la borne 5 se situe sur un plan distinct et plus élevé de celui de la borne 4 de façon à faciliter le passage direct du conducteur b au dessus de cette dernière.The two terminals 4 and 5 are electrically connected by a flexible conductive cable or an advantageously flat conductive braid 15, the ends 16 and 17 of which are preferably welded to the respective faces 18 opposite the faces 12 for engaging the fixing screws. A feature of the invention lies in the fact that the end 17 of the cable 15 is welded to the upper terminal 5 so as to form a loop 20 which extends upwards. This loop makes it possible to offer a maximum length to the cable, in particular in the space 21 of the cell 7, delimited between the terminal 5 and the bottom 22 of the cell. To ensure the seating of the terminal 5, the cell 7 comprises lateral supports 24, 25 produced in the form of shoulders situated at a level suitable for obtaining the space 21 necessary for housing the loop 20 of the cable 15. With reference to FIG. 3, it can be seen that the input of the conductor b of the terminal 5 is located on a separate and higher plane from that of the terminal 4 so as to facilitate the direct passage of the conductor b to the above the latter.

Chacune des alvéoles inférieure 6 comprend dans ses parois frontales inférieure et supérieure 26, un évidement 28 pour le passage des conducteurs a et du câble 15. Une plaque isolante 29 vient coiffer toutes les alvéoles 6, de façon à pouvoir bloquer vers le fond de chaque alvéole chacune des bornes 4. La plaque 29 comporte à cette fin des évidements ayant une forme complémentaire à la forme des parois latérales 27 pour permettre le passage de celles-ci, comme le montre notamment la figure 2. La plaque 29 est conçue pour avoir une élasticité lui permettant de se fixer ou de s'encliqueter sur les parois latérales 27 de l'alvéole ou sur le corps du bornier, à l'aide d'un dispositif de verrouillage représenté en 30 (figure 3) et comportent par exemple une saillie de verrouillage.Each of the lower cells 6 comprises in its lower and upper front walls 26, a recess 28 for the passage of the conductors a and the cable 15. An insulating plate 29 covers all the cells 6, so as to be able to block towards the bottom of each cell each of the terminals 4. The plate 29 has for this purpose recesses having a shape complementary to the shape of the side walls 27 to allow passage of these, as shown in particular in Figure 2. The plate 29 is designed to have an elasticity allowing it to be fixed or snapped onto the side walls 27 of the cell or on the body of the terminal block, using a locking device shown at 30 (Figure 3) and include for example a locking projection.

Les bornes supérieures 5 peuvent être bloquées dans leur alvéole 7, en appui sur les rebords de support 24, 25 au moyen d'un boîtier isolant 31 s'encliquetant ou se fixant sur les parois latérales 32 de l'alvéole ou sur le corps du bornier, tout en ménageant un jeu de montage vertical dont l'intérêt sera démontré plus loin. Chaque alvéole supérieure 7 comprend, dans ses surfaces frontales 34 des ouvertures 35, 36 pour le passage respectivement du conducteur b et du câble 15, d'une part, et du câble c, d'autre part.The upper terminals 5 can be locked in their cell 7, bearing on the support flanges 24, 25 by means of an insulating housing 31 which snaps or is fixed on the side walls 32 of the cell or on the body of the terminal block, while providing a vertical mounting clearance, the value of which will be demonstrated below. Each upper cell 7 comprises, in its front surfaces 34, openings 35, 36 for the passage respectively of the conductor b and of the cable 15, on the one hand, and of the cable c, on the other hand.

On décrira ci-après les différentes opérations du montage du bornier selon l'invention sur les câbles A et B.The various operations for mounting the terminal block according to the invention on cables A and B will be described below.

Lorsque toutes les bornes inférieures 4 sont câblées, c'est-à-dire placées sur les extrémités des conducteurs a, elles sont introduites dans leurs alvéoles respectives 6 et sont bloquées dans cette dernière par la mise en place de la plaque de maintien 29. Lors de l'introduction des bornes dans les alvéoles il convient d'éviter de cambrer les conducteurs pour ne pas créer des tensions mécaniques en leur sein. Le jeu vertical de montage laissé à chacune des bornes 4 dans leur alvéole 6 assure un montage facile de l'ensemble des conducteurs, même s'ils sont d'inégale longueur après montage. L'encliquetage du couvercle 29 se fait ensuite facilement en maintenant manuellement toutes les bornes 4 dans le fond de leur alvéole.When all the lower terminals 4 are wired, that is to say placed on the ends of the conductors a, they are introduced into their respective cells 6 and are blocked in the latter by the positioning of the retaining plate 29. When introducing the terminals into the cells, it is advisable to avoid bending the conductors so as not to create mechanical tensions within them. Vertical play mounting left at each of the terminals 4 in their cell 6 ensures easy mounting of all the conductors, even if they are of unequal length after mounting. The snap-fastening of the cover 29 is then easily done by manually holding all the terminals 4 in the bottom of their cell.

Lorsque le premier câble A d'amenée du courant est ainsi monté, les bornes 5 sont laissées accessibles. Le montage du deuxième câble en coupure B se fera à l'identique en coupant le câble de façon que son extrémité se présente sensiblement au milieu, selon l'axe longitudinal de l'alvéole 7 et en raccordant chaque extrémité du conducteur b préalablement dénudé dans sa borne 5. La grande souplesse et la bonne longueur du câble 15, avantageusement en forme de tresse permet de dégager aisément les bornes 5 de leur alvéole 7 et de les amener du haut vers le bas vers l'extrémité dénudée de chacun des conducteurs afin de les engager et fixer sur les extrémités de ceux-ci. Cette opération évite la manoeuvre inverse, c'est-à-dire cambrer les conducteurs pour les introduire dans les bornes 5, comme c'est le cas dans l'état de la technique.When the first current supply cable A is thus mounted, the terminals 5 are left accessible. The mounting of the second cable in cut B will be identical by cutting the cable so that its end is substantially in the middle, along the longitudinal axis of the cell 7 and by connecting each end of the conductor b previously stripped in its terminal 5. The great flexibility and the good length of the cable 15, advantageously in the form of a braid, makes it possible to easily release the terminals 5 from their cell 7 and to bring them from the top to the bottom towards the stripped end of each of the conductors so to engage them and fix on the ends of these. This operation avoids the reverse operation, that is to say arching the conductors to introduce them into the terminals 5, as is the case in the prior art.

En se référant à la figure 3, on constate que les conducteurs raccordés aux bornes 5 passent au-dessus des bornes 4 préalablement introduites dans leur alvéole 6 et coiffées par l'isolant 29. Ils peuvent donc être introduits dans les bornes 5 et les alvéoles 7 sans subir de cambrage. On évite ainsi que des efforts mécaniques soient engendrés au sein des conducteurs. Ces efforts seraient nuisibles pour la mise en place des câbles dans le bornier et pourraient provoquer à la longue le desserrage des vis 11 des bornes. Le bornier selon l'invention concerne donc dans le temps une très bonne qualité de conductibilité et une grande facilité de montage.Referring to FIG. 3, it can be seen that the conductors connected to the terminals 5 pass over the terminals 4 previously introduced into their cell 6 and capped by the insulator 29. They can therefore be introduced into the terminals 5 and the cells 7 without undergoing bending. This avoids mechanical forces being generated within the conductors. These efforts would be harmful for the installation of the cables in the terminal block and could in the long term cause the loosening of the screws 11 of the terminals. The terminal block according to the invention therefore relates in over time, a very good quality of conductivity and great ease of assembly.

Les bornes 5 sont ensuite introduites dans leur alvéole réciproque 7 en appui sur les supports latéraux 24, 25 et sont maintenues en position par le deuxième boîtier 31 mis en place par encliquetage, tout en ménageant le jeu de montage vertical susmentionné.The terminals 5 are then introduced into their reciprocal cell 7 bearing on the lateral supports 24, 25 and are held in position by the second housing 31 put in place by snap-fitting, while providing the above-mentioned vertical mounting clearance.

La figure 4 montre un deuxième mode de réalisation d'un dispositif bornier selon l'invention. Le bornier selon la figure 4 comprend deux corps de borne 40 et 41, chacun associé à un câble et conçu pour permettre le montage des quatre conducteurs. Chaque corps peut ainsi être considéré comme étant formé par assemblage des quatre bornes 4 ou 5 du mode de réalisation selon les figures 1 à 3. Les deux corps 40 et 41 sont électriquement reliés par une tresse conductrice souple 43 isolée. Le corps 40 comporte des moyens de connexion des conducteurs c d'alimentation des dispositifs utilisateurs. Le corps 40 pourrait être fixé sur un support à l'aide de vis 44 s'engageant dans des trous oblongs, le corps 41 étant maintenu en place grâce à la rigidité des conducteurs sur lequel il est connecté. On constate encore que le trou de passage 42 des vis de fixation des extrémités des conducteurs dans le bornier présente également une forme oblongue pour pouvoir assurer un jeu axial lors du montage de ces extrémités.Figure 4 shows a second embodiment of a terminal device according to the invention. The terminal block according to FIG. 4 comprises two terminal bodies 40 and 41, each associated with a cable and designed to allow the mounting of the four conductors. Each body can thus be considered to be formed by assembling the four terminals 4 or 5 of the embodiment according to FIGS. 1 to 3. The two bodies 40 and 41 are electrically connected by an insulated flexible conductive braid 43. The body 40 includes means for connecting the supply c conductors to the user devices. The body 40 could be fixed on a support using screws 44 engaging in oblong holes, the body 41 being held in place by the rigidity of the conductors to which it is connected. It can also be seen that the through hole 42 of the screws for fixing the ends of the conductors in the terminal block also has an oblong shape in order to be able to provide axial play when these ends are assembled.

Dans le mode de réalisation de la figure 5, à chaque paire de conducteurs à raccorder sont associées deux bornes 46, 47. La borne 46 comparable à la borne 5 sur les figures 1 à 3 comprend une patte de fixation 48 qui porte à son extrémité libre une petite borne de raccordement 49 du câble c et présente un évidement oblong 50 qui s'étend dans sa direction longitudinale et permet le passage d'une vis 51 susceptible de s'engager dans un trou fileté 52 d'une patte 53 de l'autre bloc bornier 47.In the embodiment of FIG. 5, each pair of conductors to be connected are associated with two terminals 46, 47. The terminal 46 comparable to terminal 5 in FIGS. 1 to 3 comprises a fixing lug 48 which carries at its end free a small connection terminal 49 of the cable c and has an oblong recess 50 which extends in its longitudinal direction and allows the passage of a screw 51 capable of engaging in a threaded hole 52 of a lug 53 of the other terminal block 47.

On comprend aisément que le trou oblong 50 assure un jeu vertical suffisant pour la fixation de la borne 46 sur la borne 47 après le montage du câble B. Ce mode de réalisation permet ainsi d'éviter toute contrainte mécanique au sein des câbles lors de leur montage sur le dispositif bornier.It is easy to understand that the oblong hole 50 provides sufficient vertical clearance for fixing the terminal 46 to the terminal 47 after the cable B has been mounted. This embodiment thus makes it possible to avoid any mechanical stress within the cables during their mounting on the terminal block device.

Il est évidement que de multiples modifications peuvent être apportées aux modes de réalisation qui viennent d'être décrits en se reportant aux figures. Il importe seulement d'assurer que la liaison entre les deux bornes associées à chaque paire de conducteurs permet un déplacement relatif lors de leur assemblage pour éviter toute contrainte mécanique au sein des conducteurs et que chaque borne puisse être montée sur l'extrémité du conducteur qu'elle doit recevoir, relativement indépendamment de l'autre borne. De ce fait, la longueur des conducteurs peut être relativement faible. Concernant le mode de réalisation selon les figures 1 à 3, il va de soi que les alvéoles de réception des bornes peuvent être réalisées directement dans le boîtier lors de la fabrication de celui-ci.It is obvious that multiple modifications can be made to the embodiments which have just been described with reference to the figures. It is only important to ensure that the connection between the two terminals associated with each pair of conductors allows relative movement during their assembly to avoid any mechanical stress within the conductors and that each terminal can be mounted on the end of the conductor that 'it must receive, relatively independently of the other terminal. As a result, the length of the conductors can be relatively short. Regarding the embodiment according to Figures 1 to 3, it goes without saying that the terminal receiving cells can be made directly in the housing during the manufacture thereof.
