TITRE : Dispositif d’interconnexion électrique pour mise à la terre de conducteurs électriques TITLE: Electrical interconnection device for earthing electrical conductors
Domaine technique de l'invention L’invention concerne d’une part, un dispositif d’interconnexion électrique pour mise à la terre de conducteurs électriques ainsi qu’un ensemble formé de conducteurs électriques en prise dans un tel dispositif et d’autre part, un procédé d’interconnexion électrique de conducteurs électriques à l’aide d’un tel dispositif. Etat de la technique Technical field of the invention The invention relates, on the one hand, to an electrical interconnection device for earthing electrical conductors as well as to an assembly formed of electrical conductors engaged in such a device and, on the other hand, a method of electrical interconnection of electrical conductors using such a device. State of the art
On connaît des dispositifs d’interconnexion électrique pour mise à la terre de conducteurs électriques, notamment des dispositifs en forme de bornier. Electrical interconnection devices are known for grounding electrical conductors, in particular devices in the form of a terminal block.
Un tel bornier est par exemple pourvu d’un corps dans lequel sont ménagés des orifices prévus pour recevoir des conducteurs électriques ayant des extrémités dénudées, et des organes de serrage prévus pour serrer les extrémités dénudées des conducteurs électriques dans les orifices pour leur assujettissement au bornier et leur interconnexion électrique avec un câble de mise à la terre, lui-même assujetti mécaniquement et électriquement au bornier. Such a terminal block is for example provided with a body in which are formed holes provided to receive electrical conductors having stripped ends, and clamping members provided to clamp the stripped ends of the electrical conductors in the holes for their attachment to the terminal block. and their electrical interconnection with an earthing cable, itself mechanically and electrically secured to the terminal block.
Généralement, les orifices sont prévus pour recevoir des conducteurs de section prédéterminée. Bien sûr, il est possible en pratique d’y introduire des conducteurs de section plus petite que la section prédéterminée mais la continuité électrique entre les conducteurs et le bornier peut être moins bonne. Generally, the orifices are designed to receive conductors of predetermined cross section. Of course, it is possible in practice to introduce conductors with a section smaller than the predetermined section, but the electrical continuity between the conductors and the terminal block may be less good.

La figure 1 représente schématiquement une machine électrique 1 , par exemple un moteur électrique triphasé, ayant trois premiers conducteurs électriques 2 qui sont interconnectés électriquement avec un câble de mise à la terre 3, à l’aide d’un dispositif d’interconnexion électrique 5. Figure 1 schematically shows an electric machine 1, for example a three-phase electric motor, having three first electric conductors 2 which are electrically interconnected with a grounding cable 3, by means of an electric interconnection device 5 .
Sur la figure 1 , les trois premiers conducteurs électriques 2 présentent une première section prédéterminée et sont pourvus chacun au moins à une extrémité libre opposée à la machine électrique 1 , d’une cosse de connexion (non représentée). Il s’agit ainsi de premiers conducteurs électriques 2 dits cossés, et de préférence à cosses plates et généralement percées. In Figure 1, the first three electrical conductors 2 have a first predetermined section and are each provided at least at a free end opposite to the electrical machine 1, with a connection terminal (not shown). These are thus the first electrical conductors 2 called lugs, and preferably flat lugs and generally pierced.
Ces premiers conducteurs électriques 2 cossés sont assujettis mécaniquement et électriquement sur un bornier 6 du dispositif 5. These first electrical conductors 2 with lugs are mechanically and electrically secured to a terminal block 6 of the device 5.
En particulier, les cosses plates des premiers conducteurs électriques 2 sont montés sur des premiers organes de connexion 27 du bornier 6 et enserrées entre une plaque inférieure 8 et une plaque supérieure 9 du bornier 6, à l’aide d’un organe de serrage 7 qui est configuré, lorsqu’il est actionné, pour rapprocher/écarter les plaques inférieure et supérieure 8 et 9 l’une de l’autre. In particular, the flat lugs of the first electrical conductors 2 are mounted on the first connection members 27 of the terminal block 6 and clamped between a lower plate 8 and an upper plate 9 of the terminal block 6, using a clamping member 7 which is configured, when actuated, to move the lower and upper plates 8 and 9 closer to / apart from each other.
Pour ce faire, les plaques inférieure et supérieure 8 et 9 sont montées sur des organes de guidages 15 du bornier 6 et au moins l’une des plaques inférieure et supérieure 8 et 9 est en translation le long de ces organes de guidages 15 et est ainsi mobile par rapport à l’autre des plaques supérieure et inférieure 9 et 8. To do this, the lower and upper plates 8 and 9 are mounted on guide members 15 of the terminal block 6 and at least one of the lower and upper plates 8 and 9 is in translation along these guide members 15 and is thus movable relative to the other of the upper and lower plates 9 and 8.
Les premiers conducteurs électriques 2 cossés sont ici montés sur un premier côté 16 du bornier 6. Dans l’exemple illustré sur la figure 1 , le câble de mise à la terre 3 est assujetti mécaniquement et électriquement par une première extrémité 10, sur le bornier 6 et s’étend depuis le même premier côté 16 du bornier 6. The first electrical conductors 2 with lugs are here mounted on a first side 16 of the terminal block 6. In the example illustrated in FIG. 1, the earthing cable 3 is mechanically and electrically secured by a first end 10, on the terminal block. 6 and extends from the same first side 16 of terminal block 6.
Le câble de mise à la terre 3 est en outre raccordé par une deuxième extrémité 11 opposée à sa première extrémité 10, à une pince de mise à la terre 12, dite par exemple pince-étau. The grounding cable 3 is also connected by a second end 11 opposite its first end 10, to a grounding clamp 12, for example called a vice clamp.
On notera, même si ceci n’est pas visible sur la figue 1 , que l’ensemble formé du dispositif d’interconnexion électrique 5, d’une portion des trois premiers conducteurs électriques 2 assujettis au bornier 6 et d’une portion du câble de mise à la terre 3 aussi assujetti au bornier 6, peut être introduit dans un sac étanche (non représenté) pourvu ou non d’une lanière pour sa suspension et ou son portage, et duquel saillent d’autres portions des trois premiers conducteurs électriques 2 et du câble de mise à la terre 3 qui cheminent respectivement vers la machine électrique 1 et vers la pince-étau 12. It will be noted, even if this is not visible in FIG. 1, that the assembly formed by the electrical interconnection device 5, of a portion of the first three electrical conductors 2 secured to terminal block 6 and a portion of the earthing cable 3 also secured to terminal block 6, can be inserted into a waterproof bag (not shown) provided or not with a strap for its suspension and / or its carrying, and from which protrude other portions of the first three electrical conductors 2 and of the earthing cable 3 which respectively travel towards the electrical machine 1 and towards the clamp 12.
La figure 2 est similaire à la figure 1 en ce qu’elle montre une machine électrique 1 ayant trois seconds conducteurs électriques 4 qui sont interconnectés électriquement avec un câble de mise à la terre 3, à l’aide du même dispositif d’interconnexion électrique 5. Figure 2 is similar to Figure 1 in that it shows an electrical machine 1 having three second electrical conductors 4 which are electrically interconnected with a grounding cable 3, using the same electrical interconnection device 5.
La figure 2 diffère de la figure 1 en ce que les trois seconds conducteurs électriques 4 présentent une seconde section prédéterminée distincte de celle des trois premiers conducteurs électriques 2, et plus précisément ici inférieure à la première section prédéterminée. FIG. 2 differs from FIG. 1 in that the three second electrical conductors 4 have a second predetermined section distinct from that of the three first electrical conductors 2, and more precisely here less than the first predetermined section.
Les trois seconds conducteurs électriques 4 sont pourvus chacun au moins à une extrémité libre opposée à la machine électrique 1 , d’une cosse (non représentée) et sont donc des conducteurs dits cossés et de préférence à cosses plates et généralement percées. The three second electrical conductors 4 are each provided, at least at a free end opposite the electrical machine 1, with a terminal (not shown) and are therefore so-called lug conductors and preferably with flat and generally pierced lugs.
En variante, les trois seconds conducteurs électriques 4 présentent des extrémités dénudées plutôt que cossées. As a variant, the three second electrical conductors 4 have stripped ends rather than thimbles.
Tout comme sur la figure 1, les seconds conducteurs électriques 4 cossés illustrés sur la figure 2 sont montés sur des seconds organes de connexion 28 du bornier 6 et assujettis mécaniquement et électriquement sur le bornier 6 du dispositif d’interconnexion électrique 5, et enserrés entre les plaques inférieure et supérieure 8 et 9 à l’aide de l’organe de serrage 7 qui rapproche les plaques inférieure et supérieure 8 et 9 en translatant au moins l’une de ces plaques le long des organes de guidage 15. As in Figure 1, the second electrical conductors 4 spade illustrated in Figure 2 are mounted on second connection members 28 of the terminal block 6 and mechanically and electrically secured to the terminal block 6 of the electrical interconnection device 5, and clamped between the lower and upper plates 8 and 9 using the clamping member 7 which brings the lower and upper plates 8 and 9 together by translating at least one of these plates along the guide members 15.
A la différence de la figure 1 , les seconds conducteurs électriques 4 cossés de la figure 2 sont ici montés sur un deuxième côté 17 du bornier 6, opposé au premier côté 16, et le câble de mise à la terre 3 est assujetti mécaniquement et électriquement par sa première extrémité 10, sur le bornier 6 et s’étend depuis le même deuxième côté 17 du bornier 6. Le câble de mise à la terre 3 est en outre raccordé par sa deuxième extrémité 11 à la pince-étau 12. Unlike Figure 1, the second electrical conductors 4 lugged in Figure 2 are here mounted on a second side 17 of the terminal block 6, opposite the first side 16, and the grounding cable 3 is mechanically and electrically secured. by its first end 10, on terminal block 6 and extends from the same second side 17 of terminal block 6. The earthing cable 3 is also connected by its second end 11 to the clamp 12.
L’ensemble formé du dispositif d’interconnexion électrique 5, d’une portion des trois seconds conducteurs électriques 4 assujettis au bornier 6 et d’une portion du câble de mise à la terre 3 aussi assujetti au bornier 6, peut également être introduit dans un sac étanche. The assembly formed by the electrical interconnection device 5, a portion of the three second electrical conductors 4 secured to the terminal block 6 and a portion of the earthing cable 3 also secured to the terminal block 6, can also be introduced into a waterproof bag.
Les figures 3 à 6 montrent plus en détail le câble de mise à la terre 3 auquel est assujetti mécaniquement par sa première extrémité 10 le dispositif d’interconnexion électrique 5 et par sa deuxième extrémité 11 la pince-étau 12. Figures 3 to 6 show in more detail the earthing cable 3 to which is mechanically secured by its first end 10 the electrical interconnection device 5 and by its second end 11 the clamp 12.
Ni les premiers conducteurs électriques 2 ni les seconds conducteurs électriques 4 ne sont montrés sur la figure 3. Neither the first electrical conductors 2 nor the second electrical conductors 4 are shown in Figure 3.
Le câble de mise à la terre 3 est pourvu à sa première extrémité 10 d’une première cosse 13 et, à sa deuxième extrémité 11 , d’une deuxième cosse 14. The grounding cable 3 is provided at its first end 10 with a first terminal 13 and, at its second end 11, with a second terminal 14.
La première cosse 13 du câble 3 est assujettie mécaniquement sur la plaque inférieure 9 du bornier 6 du dispositif 5 à l’aide d’un organe de fixation 26, du type ici vis de fixation. The first terminal 13 of the cable 3 is mechanically secured to the lower plate 9 of the terminal block 6 of the device 5 using a fixing member 26, of the type here fixing screw.
La deuxième cosse 14 du câble 3 est assujettie mécaniquement sur un corps 25 de la pince-étau 12 par un système vis-écrou 18. The second thimble 14 of the cable 3 is mechanically secured to a body 25 of the clamp 12 by a screw-nut system 18.
La pince-étau 12 est pourvu d’un mors d’étau 21 et d’une patte de montage 24 qui saillent chacun du corps 25 et qui définissent entre eux un espace de serrage 23 configuré pour recevoir par exemple un plot de mise à la terre ou bien un câble principal de mise à la terre (non représentés). The vice-gripper 12 is provided with a vice jaw 21 and a mounting tab 24 which each project from the body 25 and which define between them a clamping space 23 configured to receive, for example, a setting stud. earth or a main earth cable (not shown).
La pince-étau 12 est pourvue en outre d’un mécanisme de serrage 20 ayant une manivelle configurée pour actionner en rotation une tige filetée montée au travers de la patte de montage 24, et d’un mors complémentaire 22 fixé au bout de la tige filetée du mécanisme 20 et disposé en regard du mors d’étau 21 dans l’espace de serrage 23. The vise grip 12 is further provided with a clamping mechanism 20 having a crank configured to rotate a threaded rod mounted through the mounting tab 24, and a complementary jaw 22 attached to the end of the rod. threaded of the mechanism 20 and disposed opposite the vice jaw 21 in the clamping space 23.
L’actionnement du mécanisme de serrage 20 via sa manivelle permet d’enserrer le plot ou le câble principal de mise à la terre entre le mors d’étau 21 et le mors complémentaire 22 pour l’interconnexion électrique avec le câble de mise à la terre 3 assujetti sur la pince-étau 12.

La plaque inférieure 8 présente en outre des orifices de guidage 44 qui sont traversant et ménagés ici à chaque coin de la plaque inférieure 8. The lower plate 8 also has guide orifices 44 which pass through and are provided here at each corner of the lower plate 8.
Ces orifices de guidage 44 sont chacun pourvu d’une portion amincie et taraudée formant un puits de vissage 45 qui débouche sur la face externe 34 de la plaque inférieure 8. Chaque orifice de guidage 44 est configuré pour recevoir une extrémité d’un organe de guidage 15 respectif, avec une portion amincie et filetée de l’organe de guidage 15 qui est vissée dans le puits de vissage 45 respectif.

Comme visible sur les figures 12 à 14, la plaque supérieure 9 est pourvue de plusieurs premiers trous 46 qui sont traversant et ménagés sur le premier côté 16 (pour simplifier la description, le premier côté de la plaque supérieure porte la même référence numérique que le premier côté de la plaque inférieure et du bornier) ; et de plusieurs seconds trous 47 qui sont traversant et ménagés sur le deuxième côté 17 (pour simplifier la description, le deuxième côté le deuxième côté de la plaque supérieure porte la même référence numérique que le deuxième côté de la plaque inférieure et du bornier). As visible in Figures 12 to 14, the top plate 9 is provided with several first holes 46 which are through and formed on the first side 16 (to simplify the description, the first side of the top plate bears the same reference numeral as the first side of bottom plate and terminal block); and several second holes 47 which are through and formed on the second side 17 (to simplify the description, the second side the second side of the upper plate bears the same numerical reference as the second side of the lower plate and of the terminal block).
Les premiers trous 46 et les seconds trous 47 de la plaque supérieure 9 sont configurés pour être complémentaires respectivement des premiers orifices 40 et des seconds orifices 41 de la plaque inférieure 8. En particulier, les premiers trous 46 et les seconds trous 47 sont configurés pour être traversés respectivement par les premiers organes de connexion 27 et par les seconds organes de connexion 28. The first holes 46 and the second holes 47 of the upper plate 9 are configured to be complementary respectively to the first holes 40 and the second holes 41 of the lower plate 8. In particular, the first holes 46 and the second holes 47 are configured to be traversed respectively by the first connection members 27 and by the second connection members 28.
La plaque supérieure 9 est aussi pourvue d’un trou de serrage 48 qui est traversant et ici ménagé sensiblement au centre de la plaque supérieure 9, en complémentarité de l’orifice de serrage 42 pour permettre un serrage homogène des plaques inférieure et supérieure 8 et 9. The upper plate 9 is also provided with a clamping hole 48 which is through and here formed substantially in the center of the upper plate 9, in complementarity with the clamping hole 42 to allow homogeneous clamping of the lower and upper plates 8 and 9.
La plaque supérieure 9 présente en outre des trous de guidage 49 qui sont traversant et ménagés ici à chaque coin de la plaque supérieure 8, en complémentarité des orifices de guidage 44 pour permettre le coulissement des organes de guidage 15 au travers des trous de guidage 49. The upper plate 9 also has guide holes 49 which are passing through and formed here at each corner of the upper plate 8, in complementarity with the guide holes 44 to allow the sliding of the guide members 15 through the guide holes 49. .
Ces trous de guidage 49 sont pourvus chacun d’un épaulement 50, du côté de la face externe 36 de la plaque supérieure 8. These guide holes 49 are each provided with a shoulder 50, on the side of the external face 36 of the upper plate 8.
Chaque épaulement 50 forme une butée interne pour une tête d’un organe de guidage 15 respectif, de sorte à maintenir la plaque supérieure 9 en regard de la plaque inférieure 8, même si l’organe de serrage 7 est totalement desserré. Ici, les premiers organes de connexion 27 présentent chacun une tête de laquelle saille une tige de connexion ayant un premier diamètre prédéterminé qui correspond sensiblement à celui du perçage réalisé dans la cosse plate d’un premier conducteur électrique 2. Ici les premiers organes de connexion 27 sont assujettis à la plaque inférieure 8. Each shoulder 50 forms an internal stop for a head of a respective guide member 15, so as to keep the upper plate 9 facing the lower plate 8, even if the clamping member 7 is completely loosened. Here, the first connection members 27 each have a head from which protrudes a connection rod having a first predetermined diameter which corresponds substantially to that of the bore made in the flat terminal of a first electrical conductor 2. Here the first connection members 27 are secured to the bottom plate 8.
En particulier, dans l’exemple illustré, la tête de chaque premier organe de connexion 27 est introduite dans la portion élargie d’un premier orifice 40 respectif et une portion de la tige de connexion respective est vissée dans la portion amincie et droite d’un premier orifice 40 respectif. In particular, in the example illustrated, the head of each first connection member 27 is introduced into the enlarged portion of a respective first orifice 40 and a portion of the respective connection rod is screwed into the thinned and straight portion of a respective first orifice 40.
Le reste de la tige de connexion de chaque premier organe de connexion 27 s’étend vers la plaque supérieure 9 et son extrémité se trouve en regard d’un premier trou 46 respectif de la plaque supérieure 9. The remainder of the connection rod of each first connection member 27 extends towards the upper plate 9 and its end is opposite a respective first hole 46 of the upper plate 9.
Ici, les seconds organes de connexion 28 sont similaires aux premiers organes de connexion 27 en ce qu’ils présentent chacun une tête de laquelle saille une tige de connexion et sont assujettis à la plaque inférieure 8. Here, the second connection members 28 are similar to the first connection members 27 in that they each have a head from which protrudes a connection rod and are secured to the lower plate 8.
En particulier, la tête de chaque second organe de connexion 28 est introduite dans la portion élargie d’un second orifice 41 respectif et une portion de la tige de connexion respective est vissée dans la portion amincie et droite d’un second orifice 41 respectif. In particular, the head of each second connection member 28 is introduced into the enlarged portion of a respective second orifice 41 and a portion of the respective connection rod is screwed into the thinned and straight portion of a respective second orifice 41.
Le reste de la tige de connexion de chaque second organe de connexion 28 s’étend vers la plaque supérieure 9 et son extrémité se trouve en regard d’un second trou 47 respectif de la plaque supérieure 9. The remainder of the connection rod of each second connection member 28 extends towards the upper plate 9 and its end is opposite a respective second hole 47 of the upper plate 9.
A la différence des premiers organes de connexion 27, les tiges de connexion des seconds organes de connexion 28 ont un second diamètre prédéterminé qui correspond sensiblement à celui du perçage réalisé dans la cosse plate d’un second conducteur électrique 4. Unlike the first connection members 27, the connection rods of the second connection members 28 have a second predetermined diameter which corresponds substantially to that of the bore made in the flat terminal of a second electrical conductor 4.
Dans l’exemple illustré, le second diamètre prédéterminé des tiges de connexion des seconds organes de connexion 28 est inférieur au premier diamètre prédéterminé des tiges de connexion des premiers organes de connexion 27. L’organe de serrage 7 est pourvu d’une portion d’actionnement 29, par exemple une tête de préhension en forme de papillon, et d’une tige de serrage 30 qui présente une tête et une portion filetée. In the example illustrated, the second predetermined diameter of the connection rods of the second connection members 28 is less than the first predetermined diameter of the connection rods of the first connection members 27. The clamping member 7 is provided with an actuating portion 29, for example a gripping head in the form of a butterfly, and with a clamping rod 30 which has a head and a threaded portion.
Ici l’organe de serrage 7 est assujetti à la plaque inférieure 8. En particulier, dans l’exemple illustré, la tête de la tige de serrage 30 est introduite dans la portion élargie de l’orifice de serrage 42 et une portion filetée de la tige de serrage 30 est vissée dans la portion amincie et droite de l’orifice de serrage 42. Here the clamping member 7 is secured to the lower plate 8. In particular, in the example illustrated, the head of the clamping rod 30 is introduced into the enlarged portion of the clamping hole 42 and a threaded portion of the clamping rod 30 is screwed into the thinned and straight portion of the clamping hole 42.
Le reste de la tige de serrage 30 s’étend vers la plaque supérieure 9 jusqu’à traverser le trou de serrage 48 et saillir de la face externe 36 de la plaque supérieure 9. The remainder of the clamping rod 30 extends towards the upper plate 9 until it passes through the clamping hole 48 and protrudes from the outer face 36 of the upper plate 9.
La portion d’actionnement 29 est montée en prise et vissée sur la portion de la tige de serrage 30 qui saille de la face externe 36 de la plaque supérieure 9. Ainsi, lorsque la portion d’actionnement 29 est mise en rotation dans un sens de vissage, elle vient en appui sur la face externe 36 de la plaque supérieure 9 de sorte à la rapprocher de la plaque inférieure 8, et inversement lorsqu’elle est mise en rotation dans un sens opposé au sens de vissage. The actuating portion 29 is mounted in engagement and screwed onto the portion of the clamping rod 30 which protrudes from the outer face 36 of the upper plate 9. Thus, when the actuating portion 29 is rotated in one direction screwing, it bears on the outer face 36 of the upper plate 9 so as to bring it closer to the lower plate 8, and vice versa when it is rotated in a direction opposite to the screwing direction.
Chacun des organes de guidage 15 est pourvu, à une première extrémité, d’une portion amincie et filetée 31 qui est vissée dans un puits de vissage 45 ménagé dans un orifice de guidage 44 de la plaque inférieure 8, et à une extrémité libre opposée à son extrémité amincie, d’une tête (non représentée) qui est située au-delà de l’épaulement 50 ménagé dans le trou de guidage 49 de la plaque supérieure 9 pour venir en butée contre ce dernier, lorsque les plaques inférieure et supérieure 8 et 9 sont écartées au maximum. Each of the guide members 15 is provided, at a first end, with a thinned and threaded portion 31 which is screwed into a screw hole 45 formed in a guide hole 44 of the lower plate 8, and at an opposite free end at its thinned end, a head (not shown) which is located beyond the shoulder 50 formed in the guide hole 49 of the upper plate 9 to abut against the latter, when the lower and upper plates 8 and 9 are separated to the maximum.
Le bornier 6 est en outre pourvu d’organes de rappel 32, ici formés par exemple par des ressorts de compression, qui sont montés autour des organes de guidage 15 entre les faces internes 33, 35 des plaques inférieure et supérieure 8, 9 respectives. Ces organes de rappel 32 permettent de faciliter l’écartement des plaques inférieure et supérieure 8 et 9 lorsque l’organe de serrage 7 est desserré. Le dispositif 5 permet, grâce aux premiers et seconds organe de connexion 27 et 28 assujettis sur la plaque inférieure 8 et de diamètres différents, de proposer un bornier 6 sur lequel il est possible d’assujettir mécaniquement et électriquement les premiers ou les seconds conducteurs électriques 2, 4 qui sont de différentes sections. The terminal block 6 is further provided with return members 32, here formed for example by compression springs, which are mounted around the guide members 15 between the internal faces 33, 35 of the respective lower and upper plates 8, 9. These return members 32 make it possible to facilitate the separation of the lower and upper plates 8 and 9 when the clamping member 7 is loosened. The device 5 makes it possible, thanks to the first and second connection members 27 and 28 secured to the lower plate 8 and of different diameters, to provide a terminal block 6 on which it is possible to mechanically and electrically secure the first or the second electrical conductors. 2, 4 which are from different sections.
Le cas échéant, les cosses plates des premiers ou des seconds conducteurs électriques 2, 4 sont montés sur les premiers ou les seconds organes de connexion 27 et 28 et la plaque supérieure 9 est translatée vers la plaque inférieure 8 à l’aide de l’organe de serrage 7, jusqu’à ce que la face interne 35 de la plaque supérieure 9 arrive en butée sur les cosses plates des premiers ou des seconds conducteurs électriques 2, 4 pour assurer une interconnexion électrique en vue de la mise à la terre des conducteurs respectifs. Where appropriate, the flat lugs of the first or second electrical conductors 2, 4 are mounted on the first or the second connection members 27 and 28 and the upper plate 9 is translated towards the lower plate 8 using the clamping member 7, until the internal face 35 of the upper plate 9 comes into abutment on the flat lugs of the first or second electrical conductors 2, 4 to ensure an electrical interconnection with a view to the grounding of the respective drivers.
Dans le dispositif 5 décrit ci-dessus, l’agencement de l’organe de serrage 7 et des plaques inférieure et supérieure 8 et 9 permettent d’assujettir simultanément plusieurs conducteurs, soit les premiers conducteurs électriques 2 montés sur les premiers organes de connexion 27, soit les seconds conducteurs électriques 4 montés sur les seconds organes de connexion 28. In the device 5 described above, the arrangement of the clamping member 7 and the lower and upper plates 8 and 9 make it possible to simultaneously secure several conductors, ie the first electrical conductors 2 mounted on the first connection members 27 , or the second electrical conductors 4 mounted on the second connection members 28.
Généralement, le dispositif 5 est utilisé pour interconnecter des conducteurs similaires pour assurer une bonne continuité électrique. Toutefois, il est possible d’utiliser le dispositif 5 pour assujettir différents types de conducteurs, avec par exemple un ou plusieurs premiers conducteurs électriques 2 montés sur un ou plusieurs premiers organes de connexion 27 respectifs et un ou plusieurs seconds conducteurs électriques 4 montés sur un ou plusieurs seconds organes de connexion 28 respectifs. Cependant il est possible que les conducteurs de plus petite section soient moins enserrés que ceux de plus grosses section. Generally, device 5 is used to interconnect similar conductors to ensure good electrical continuity. However, it is possible to use the device 5 to secure different types of conductors, with for example one or more first electrical conductors 2 mounted on one or more respective first connection members 27 and one or more second electrical conductors 4 mounted on a or more respective second connection members 28. However, it is possible that conductors with a smaller cross-section are less clamped than those with larger cross-section.
Pour l’interconnexion du dispositif 5 avec les premiers et/ou seconds conducteurs électriques 2, 4, le procédé comporte les étapes ci-dessous. For the interconnection of the device 5 with the first and / or second electrical conductors 2, 4, the method comprises the steps below.
S’il s’agit des premiers conducteurs électriques 2 à cosses plates, ils sont montés sur les premiers organes de connexion 27 du bornier 6. Il faut bien sûr que les plaques inférieure et supérieure 8 et 9 soient suffisamment écartées pour introduire les conducteurs. Dans la négative, il faut écarter ces plaques en actionnant l’organe de serrage 7, les organes de rappel 32 aidant à l’écartement des plaques. Ensuite, l’organe de serrage 7 est actionné par le biais de sa portion d’actionnement 29 et les plaques 8 et 9 se rapprochent jusqu’à ce que la plaque supérieure 9 entre en contact avec les cosses plates des premiers conducteurs électriques 2 pour permettre l’interconnexion électrique. La translation de la plaque supérieure 9 se fait en coulissant le long des organes de guidage 15. If these are the first electrical conductors 2 with flat lugs, they are mounted on the first connection members 27 of the terminal block 6. It is of course necessary that the lower and upper plates 8 and 9 are sufficiently apart to introduce the conductors. If not, these plaques must be removed by actuating the clamping member 7, the return members 32 assisting in the separation of the plates. Then, the clamping member 7 is actuated through its actuating portion 29 and the plates 8 and 9 approach until the top plate 9 comes into contact with the flat lugs of the first electrical conductors 2 to allow electrical interconnection. The translation of the upper plate 9 takes place by sliding along the guide members 15.
S’il s’agit des seconds conducteurs électriques 2 à cosses plates, ils sont montés sur les seconds organes de connexion 28 du bornier 6. Il faut bien sûr que les plaques inférieure et supérieure 8 et 9 soient suffisamment écartées pour introduire les conducteurs. Dans la négative, il faut écarter ces plaques en actionnant l’organe de serrage 7, les organes de rappel 32 aidant à l’écartement des plaques. Ensuite, l’organe de serrage 7 est actionné par le biais de sa portion d’actionnement 29 et les plaques 8 et 9 se rapprochent jusqu’à ce que la plaque supérieure 9 entre en contact avec les cosses plates des seconds conducteurs électriques 4 pour permettre l’interconnexion électrique. La translation de la plaque supérieure 9 se fait aussi en coulissant le long des organes de guidage 15. If these are the second electrical conductors 2 with flat lugs, they are mounted on the second connection members 28 of the terminal block 6. It is of course necessary that the lower and upper plates 8 and 9 are sufficiently apart to introduce the conductors. If not, these plates must be moved apart by actuating the clamping member 7, the return members 32 helping to separate the plates. Then, the clamping member 7 is actuated through its actuating portion 29 and the plates 8 and 9 approach until the top plate 9 comes into contact with the flat lugs of the second electrical conductors 4 to allow electrical interconnection. The translation of the upper plate 9 is also done by sliding along the guide members 15.
Si les seconds conducteurs électriques 2 sont dénudés plutôt que cossés, les extrémités de ces conducteurs sont enroulées autour des seconds organes de connexion 28 du bornier 6. If the second electrical conductors 2 are stripped rather than lipped, the ends of these conductors are wound around the second connection members 28 of the terminal block 6.
On notera que le câble de mise à la terre 3 est généralement pré monté sur la face externe 34 de la plaque inférieure 8 du bornier 6, avec son organe de fixation 26 qui est assujetti dans l’orifice de fixation 43. It will be noted that the grounding cable 3 is generally pre-mounted on the external face 34 of the lower plate 8 of the terminal block 6, with its fixing member 26 which is secured in the fixing hole 43.
Le fait de pouvoir disposer différentes sections de conducteurs entre les plaques inférieure et supérieure 8 et 9 permet d’avoir un bornier particulièrement flexible tout en restant compact. The fact of being able to have different sections of conductors between the lower and upper plates 8 and 9 makes it possible to have a particularly flexible terminal block while remaining compact.
Des variantes non illustrées sont décrites ci-dessous. Variants not shown are described below.
Le bornier peut être pourvu de plus ou moins de premiers et/ou de seconds organes de connexion. Le bornier peut être pourvu de troisième et/ou quatrième organes de connexion prévus pour des conducteurs de sections différentes de celles des premier et seconds conducteurs. Au moins certains des organes de connexion peuvent être montés sur la plaque supérieure plutôt que sur la plaque inférieure. The terminal block can be provided with more or less first and / or second connection members. The terminal block may be provided with third and / or fourth connection members provided for conductors of sections different from those of the first and second conductors. At least some of the connectors can be mounted on the top plate rather than the bottom plate.
L’organe de serrage peut être configuré pour déplacer la plaque inférieure plutôt que la plaque supérieure. Le bornier peut être pourvu de plusieurs organes de serrage, disposés sur la même plaque ou bien sur des plaques différentes. The clamp can be configured to move the bottom plate rather than the top plate. The terminal block can be provided with several clamping members, arranged on the same plate or on different plates.
Le câble de mise à la terre peut être monté sur la plaque supérieure plutôt que sur la plaque inférieure. The ground wire can be mounted on the top plate rather than the bottom plate.
Le bornier peut comporter plus ou moins d’organes de guidage. Les organes de guidage peuvent ne pas être situés dans les coins du bornier mais plutôt sensiblement au centre du bornier ou être régulièrement répartis sur le pourtour du bornier. The terminal block may have more or less guide members. The guide members may not be located in the corners of the terminal block but rather substantially in the center of the terminal block or be evenly distributed around the periphery of the terminal block.
Les organes de guidage peuvent être assujettis à la plaque supérieure plutôt qu’à la plaque inférieure, laquelle est ainsi translatée le long des organes de guidage. The guide members can be secured to the upper plate rather than the lower plate, which is thus translated along the guide members.
Les organes de guidage et/ou l’organe de serrage peuvent être soudés plutôt que vissés sur le bornier. The guides and / or the clamp can be welded rather than screwed to the terminal block.
Le bornier peut comporter un organe de rappel complémentaire monté autour de la tige de serrage de l’organe de serrage. Le bornier peut être dépourvu d’organes de rappel. The terminal block may include a complementary return member mounted around the clamping rod of the clamping member. The terminal block may be without return devices.
La pince-étau peut être remplacée par une pince élastique, par exemple une pince crocodile, ou encore un étau de terre avec cadenas de consignation ou encore une micro-pince. The vise grip can be replaced by an elastic clip, for example an alligator clip, or an earth vise with a lockout padlock or even a micro-clip.
On rappelle plus généralement que l’invention ne se limite pas aux exemples décrits et représentés. It is recalled more generally that the invention is not limited to the examples described and shown.
