TITRE : Dispositif d’interconnexion électrique pour mise à la terre d’un conducteur électrique TITLE: Electrical interconnection device for earthing an electrical conductor
Domaine technique de l'invention L’invention concerne d’une part un dispositif d’interconnexion électrique pour mise à la terre d’un conducteur électrique ainsi qu’un ensemble formé d’un tel dispositif en prise sur un conducteur électrique et d’autre part, un procédé d’interconnexion électrique à l’aide d’un tel dispositif pour mise à la terre d’un conducteur électrique logé dans une armoire électrique et situé derrière un autre conducteur électrique. Technical field of the invention The invention relates on the one hand to an electrical interconnection device for earthing an electrical conductor as well as to an assembly formed of such a device engaged on an electrical conductor and of on the other hand, a method of electrical interconnection using such a device for earthing an electrical conductor housed in an electrical cabinet and located behind another electrical conductor.
Etat de la technique 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 pince pouvant être montés au bout d’une perche. Une telle pince est par exemple prévue pour la mise à la terre d’un conducteur électrique nu et enserre directement le conducteur nu logé dans une armoire électrique, aussi appelée cellule, qui peut comporter une pluralité de conducteurs isolés et/ou nus. There are known electrical interconnection devices for grounding electrical conductors, including clamp-shaped devices that can be mounted at the end of a pole. Such a clamp is for example provided for earthing a bare electrical conductor and directly encloses the bare conductor housed in an electrical cabinet, also called a cell, which may include a plurality of insulated and / or bare conductors.
Cette pince est pourvue d’une base, de deux mors fixés par une extrémité respective sur la base et d’un mécanisme pour rapprocher/écarter les mors l’un de l’autre en vue d’enserrer/relâcher le conducteur nu. This gripper is provided with a base, two jaws attached at a respective end to the base, and a mechanism for moving the jaws closer / apart from each other to grip / release the bare conductor.
Les mors sont disposés en regard et à distance l’un de l’autre et définissent une zone de réception pour le conducteur nu. The jaws are arranged opposite and at a distance from each other and define a reception area for the bare conductor.
Cette zone de réception présente un espace variable entre une configuration d’enserrement du conducteur nu pour son interconnexion électrique en vue de sa mise à la terre, et une configuration de relâchement ou d’insertion. This receiving area has a variable space between a clamping configuration of the bare conductor for its electrical interconnection for grounding, and a release or insertion configuration.
La base d’une telle pince peut comporter une portion mobile et inclinable pour orienter les mors dans une direction prédéterminée, de sorte à faciliter l’accès au conducteur électrique à interconnecter. The base of such a clamp may include a movable and tilting portion to orient the jaws in a predetermined direction, so as to facilitate access to the electrical conductor to be interconnected.
Exposé de l’invention L’invention vise à fournir un dispositif d’interconnexion électrique pour mise à la terre d’un conducteur électrique, d’un genre similaire et présentant un système de mors rendant particulièrement simple et commode son utilisation. L’invention a ainsi pour objet, selon un premier aspect, un dispositif d’interconnexion électrique pour mise à la terre d’un conducteur électrique, comportant une base, un système à deux mors assujettis par une extrémité respective à la base et s’étendant en regard et à distance l’un de l’autre de sorte à définir une zone de réception entre eux, et un mécanisme assujetti à la base et configuré pour rapprocher/écarter les mors l’un de l’autre et ainsi faire varier un espace de la zone de réception entre une configuration d’enserrement du conducteur électrique pour son interconnexion électrique en vue de sa mise à la terre, et une configuration de relâchement ou d’insertion ; caractérisé en ce que les deux mors s’étendent longitudinalement et présentent des faces internes respectives qui sont agencées de sorte à ménager dans la zone de réception et au moins dans la configuration d’enserrement, un premier logement distal et un second logement proximal situé entre le premier logement distal et la base, avec le dispositif d’interconnexion électrique qui est configuré pour recevoir ledit conducteur électrique à interconnecter pour sa mise à la terre dans le premier logement distal et pour recevoir un autre conducteur électrique dans son second logement proximal. Disclosure of the invention The invention aims to provide an electrical interconnection device for earthing an electrical conductor, of a similar type and having a jaw system making its use particularly simple and convenient. The invention thus relates, according to a first aspect, to an electrical interconnection device for earthing an electrical conductor, comprising a base, a two-jaw system secured by a respective end to the base and s' extending opposite and at a distance from each other so as to define a reception area between them, and a mechanism attached to the base and configured to bring the jaws closer to / apart from each other and thus to vary a space in the receiving area between a configuration of clamping the electrical conductor for its electrical interconnection for grounding, and a release or insertion configuration; characterized in that the two jaws extend longitudinally and have respective internal faces which are arranged so as to provide in the reception area and at least in the clamping configuration, a first distal housing and a second proximal housing located between the first distal housing and the base, with the electrical interconnection device which is configured to receive said electrical conductor to be interconnected for its grounding in the first distal housing and to receive another electrical conductor in its second proximal housing.
Le dispositif selon l’invention permet, grâce à la configuration de son système à deux mors, d’établir une interconnexion électrique avec un conducteur en vue de sa mise à la terre et qui se trouve par exemple juste derrière un autre conducteur électrique qui ne doit pas être interconnecté. The device according to the invention makes it possible, thanks to the configuration of its two-jaw system, to establish an electrical interconnection with a conductor with a view to its earthing and which is for example just behind another electrical conductor which is not must not be interconnected.
En particulier, le conducteur électrique qui n’a pas à être interconnecté peut être reçu dans le second logement proximal tandis que le conducteur électrique qui doit être interconnecté en vue de sa mise à la terre peut être reçu dans le premier logement distal. En d’autres termes, grâce au système à deux mors du dispositif selon l’invention et en particulier grâce à la forme des deux mors, il est possible d’interconnecter un conducteur électrique en vue de sa mise à la terre, sans que l’autre conducteur qui se trouve juste devant et qui ne doit pas être interconnecté ne vienne gêner l’interconnexion du conducteur électrique se trouvant juste derrière. In particular, the electrical conductor which need not be interconnected may be received in the second proximal housing while the electrical conductor which is to be interconnected for grounding may be received in the distal first housing. In other words, thanks to the two-jaw system of the device according to the invention and in particular thanks to the shape of the two jaws, it is possible to interconnect an electrical conductor with a view to its earthing, without that the other conductor which is just in front and which must not be interconnected does not interfere with the interconnection of the electrical conductor located just behind.

Description détaillée detailed description
La figure 1 représente schématiquement une armoire électrique 1 , aussi appelée cellule, dans laquelle sont logés une pluralité de conducteurs électriques, dont au moins un premier conducteur électrique 2 à interconnecter en vue de sa mise à la terre et un second conducteur électrique 3 qui n’est pas à interconnecter et à mettre à la terre, avec le second conducteur électrique 3 qui se trouve devant le premier conducteur électrique 2. FIG. 1 schematically represents an electrical cabinet 1, also called a cell, in which are housed a plurality of electrical conductors, including at least a first electrical conductor 2 to be interconnected with a view to its earthing and a second electrical conductor 3 which n 'is not to be interconnected and earthed, with the second electrical conductor 3 which is located in front of the first electrical conductor 2.
Le premier conducteur électrique 2 peut être nu ou cossé et se trouver derrière le second conducteur électrique 3 qui peut être isolé. The first electrical conductor 2 can be bare or spade and be located behind the second electrical conductor 3 which can be insulated.
Les notions de devant/derrière s’entendent au regard de l’accès à l’armoire électrique 1. The concepts of front / back are understood with regard to access to the electrical cabinet 1.
En particulier, l’armoire électrique 1 est pourvue d’une trappe d’accès 4 qui dans sa configuration ouverte comme sur la figure 1, donne accès à une ouverture 9 par laquelle un opérateur 5 passe un dispositif d’interconnexion électrique 6 monté au bout d’une perche 7, pour interconnecter le premier conducteur électrique 2 se trouvant dans l’armoire électrique 1 en vue de sa mise à la terre via un câble de terre 8. In particular, the electrical cabinet 1 is provided with an access hatch 4 which, in its open configuration as in FIG. 1, gives access to an opening 9 through which an operator 5 passes an electrical interconnection device 6 mounted on the end of a pole 7, to interconnect the first electrical conductor 2 located in the electrical cabinet 1 with a view to its earthing via an earth cable 8.
Ainsi, l’agencement du premier conducteur électrique 2 et du second conducteur électrique 3 dans l’armoire électrique 1 est tel que c’est le second conducteur électrique 3 qui se trouve au plus près de l’ouverture d’accès 9 alors que c’est le premier conducteur électrique 2 qui nécessite d’être interconnecté électrique et mis à la terre à l’aide du dispositif d’interconnexion électrique 6. Thus, the arrangement of the first electrical conductor 2 and of the second electrical conductor 3 in the electrical cabinet 1 is such that it is the second electrical conductor 3 which is located closest to the access opening 9 then that it is the first electrical conductor 2 which needs to be electrically interconnected and earthed using the electrical interconnection device 6.
Les figures 2 à 4 montrent de manière isolée un ensemble formé du dispositif d’interconnexion électrique 6 en configuration d’enserrement, et des premier et second conducteurs électriques 2 et 3 pris dans le dispositif 6 ; tandis que les figures 5 et 6 puis 7 et 8 montrent de manière isolée, respectivement le dispositif d’interconnexion électrique en configuration de relâchement ou d’insertion, sans les premier et second conducteurs électriques, et l’un des mors de ce dispositif. En particulier, le dispositif d’interconnexion électrique 6 comporte une base 10 ayant une première partie 11 et une deuxième partie 12 qui peut être mobile en rotation par rapport à la première partie 11, par exemple par serrage/desserrage de vis de fixation. Figures 2 to 4 show in isolation an assembly formed of the electrical interconnection device 6 in the clamping configuration, and the first and second electrical conductors 2 and 3 taken from the device 6; while Figures 5 and 6 then 7 and 8 show in isolation, respectively the electrical interconnection device in the release or insertion configuration, without the first and second electrical conductors, and one of the jaws of this device. In particular, the electrical interconnection device 6 comprises a base 10 having a first part 11 and a second part 12 which can be movable in rotation with respect to the first part 11, for example by tightening / loosening fixing screws.
Le dispositif d’interconnexion électrique 6 comporte en outre un système à deux mors 13, chacun des mors 13 étant assujetti par une première extrémité 20 à la deuxième partie de la base 10. The electrical interconnection device 6 further comprises a two-jaw system 13, each of the jaws 13 being secured by a first end 20 to the second part of the base 10.
Ainsi, la rotation de la deuxième partie 12 de la base 10 par rapport à sa première partie 11 peut permettre d’orienter les mors 13 dans une direction prédéterminée. Dans l’exemple illustré sur les figures 2 à 6, les première et deuxième parties 11 et 12 de la base 10 sont sensiblement alignées axialement et les mors 13 s’étendent dans la même direction axiale. Thus, the rotation of the second part 12 of the base 10 relative to its first part 11 can make it possible to orient the jaws 13 in a predetermined direction. In the example illustrated in Figures 2 to 6, the first and second parts 11 and 12 of the base 10 are substantially axially aligned and the jaws 13 extend in the same axial direction.
Le système à mors 13 est pourvu de deux organes de liaison électrique 14 fixés chacun par une première extrémité 18 sur un des mors 13 et par une deuxième extrémité 19 opposée à la première extrémité 18 à la deuxième partie 12 de la base 10. The jaw system 13 is provided with two electrical connection members 14 each fixed by a first end 18 on one of the jaws 13 and by a second end 19 opposite the first end 18 at the second part 12 of the base 10.
Dans l’exemple illustré, les organes de liaison électrique 14 sont formés par des câblettes qui courent le long de chacun des mors 13 et qui cheminent à l’extérieur de la base 10. Le système à mors 13 est en outre pourvu d’un organe de rappel 17, ici un ressort de compression, interposé entre les mors 13. Le dispositif d’interconnexion électrique 6 comporte en outre un mécanisme 15 assujetti à la base 10 et configuré pour approcher/écarter les mors 13 l’un de l’autre. In the example illustrated, the electrical connection members 14 are formed by cables which run along each of the jaws 13 and which run outside the base 10. The jaw system 13 is also provided with a return member 17, here a compression spring, interposed between the jaws 13. The electrical interconnection device 6 further comprises a mechanism 15 secured to the base 10 and configured to bring the jaws 13 towards / away from one another.
Les mors 13 s’étendent longitudinalement en regard et à distance l’un de l’autre de sorte à définir une zone de réception 16 entre eux, laquelle présente un espace variable entre une configuration d’enserrement dans laquelle les mors sont resserrés et une configuration de relâchement ou d’insertion dans laquelle les mors sont écartés. The jaws 13 extend longitudinally facing and at a distance from each other so as to define a reception zone 16 between them, which has a variable space between a gripping configuration in which the jaws are tightened and a release or insertion configuration in which the jaws are spread apart.
C’est l’actionnement du mécanisme 15 qui permet de passer de l’une à l’autre des configurations d’enserrement et de relâchement ou d’insertion. It is the actuation of the mechanism 15 which makes it possible to switch from one to the other of the clamping and releasing or insertion configurations.
En particulier, les deux mors 13 présentent ici des faces internes 21 respectives qui sont agencées de sorte à ménager dans la zone de réception 16 et au moins dans la configuration d’enserrement, un premier logement distal 23 et un second logement proximal 24 situé entre le premier logement distal 23 et la base 10. In particular, the two jaws 13 here have respective internal faces 21 which are arranged so as to provide in the reception zone 16 and at least in the clamping configuration, a first distal housing 23 and a second proximal housing 24 located between the first distal housing 23 and the base 10.
Dans l’exemple illustré et comme visible notamment sur les figures 7 et 8, la face interne 21 de chacun des mors 13 est droite et globalement rectiligne. In the example illustrated and as visible in particular in Figures 7 and 8, the internal face 21 of each of the jaws 13 is straight and generally rectilinear.
Par exemple, les mors 13 peuvent s’étendre sur une longueur comprise entre environ 150 mm et 300 mm voire au-delà de 300 mm. For example, the jaws 13 can extend over a length of between about 150 mm and 300 mm or even beyond 300 mm.
Les mors 13 comportent chacun une portion d’extrémité recourbée vers l’intérieur 22, à l’opposé de la première extrémité respective 20, et définissant au moins partiellement le premier logement distal 23. The jaws 13 each have an inwardly curved end portion 22, opposite the respective first end 20, and at least partially defining the first distal housing 23.
Chaque mors 13 est en outre pourvu d’un siège 25 ménagé sur sa face interne respective 21 et prévu pour recevoir l’organe de rappel 17. Each jaw 13 is further provided with a seat 25 provided on its respective internal face 21 and designed to receive the return member 17.
Chaque siège 25 est ici formé par une paroi annulaire ménagée en saillie de la face interne 21 respective. Each seat 25 is here formed by an annular wall provided projecting from the respective internal face 21.
Les deux mors 13 présentent des faces externes 35, opposées aux faces internes 21 , et sur lesquelles sont ici fixées les câblettes 14 par leur première extrémité respective 18, par exemple via des vis de fixation comme visible notamment sur les figures 4 et 5. Les premier et deuxième conducteurs électriques 2 et 3 sont reçus dans la zone de réception 16, avec le premier conducteur électrique 2 qui est reçu dans le premier logement distal 23 pour son interconnexion et sa mise à la terre, tandis que le second conducteur électrique 3 est reçu dans le second logement proximal 24. The two jaws 13 have external faces 35, opposite the internal faces 21, and on which the cables 14 are fixed here by their respective first end 18, for example via fixing screws as can be seen in particular in FIGS. 4 and 5. The first and second electrical conductors 2 and 3 are received in the receiving area 16, with the first electrical conductor 2 which is received in the first distal housing 23 for its interconnection and grounding, while the second electrical conductor 3 is received in the second proximal housing 24.
Ainsi, le premier conducteur électrique 2 se trouve à l’extrémité proximale du dispositif 6, le second conducteur électrique 3 se trouve entre le premier conducteur électrique 2 et la base 10, et l’organe de rappel se trouve ici entre le second conducteur électrique 3 et la base 10. Comme visible sur les figures 3 et 4, le dispositif 6 se trouve dans sa configuration d’enserrement dans laquelle les mors 13 enserrent partiellement le premier conducteur électrique 2 dans le premier logement distal 23 de sorte à assurer une interconnexion électrique entre le premier conducteur électrique 2 et les mors 13 ; tandis que les mors 13 n’enserrent pas le second conducteur électrique 3 dans le second logement proximal 24. Thus, the first electrical conductor 2 is located at the proximal end of the device 6, the second electrical conductor 3 is located between the first electrical conductor 2 and the base 10, and the return member is located here between the second electrical conductor. 3 and the base 10. As visible in Figures 3 and 4, the device 6 is in its clamping configuration in which the jaws 13 partially surround the first electrical conductor 2 in the first distal housing 23 so as to provide an interconnection. electrical between the first electrical conductor 2 and the jaws 13; while the jaws 13 do not enclose the second electrical conductor 3 in the second proximal housing 24.
Ici, le premier conducteur électrique 2 a une section supérieure à celle du second conducteur électrique 3. Here, the first electrical conductor 2 has a section greater than that of the second electrical conductor 3.
Ceci est possible grâce au dimensionnement des mors 13 du dispositif 6, notamment leur longueur, vis-à-vis des sections des conducteurs qui peuvent être reçus dans la zone de réception 16 et plus particulièrement dans les espaces définis respectivement par le premier logement distal 23 et le second logement proximal 24. This is possible thanks to the dimensioning of the jaws 13 of the device 6, in particular their length, with respect to the sections of the conductors which can be received in the reception zone 16 and more particularly in the spaces defined respectively by the first distal housing 23 and the second proximal housing 24.
Ceci peut dépendre aussi de l’amplitude d’écartement et de rapprochement des mors qui dépend notamment de la forme de la base 10 et du mécanisme 15 configuré pour rapprocher/écarter les mors l’un de l’autre. This may also depend on the amplitude of the spacing and approach of the jaws which depends in particular on the shape of the base 10 and the mechanism 15 configured to bring the jaws closer to / apart from each other.
En particulier, le mécanise 15 configuré pour rapprocher/écarter les mors 13 l’un de l’autre est ici monté mobile en rotation et en translation sur la première partie 11 de la base 10. In particular, the mechanism 15 configured to bring the jaws 13 closer to / apart from one another is here mounted mobile in rotation and in translation on the first part 11 of the base 10.
La rotation du mécanisme 15 configuré pour rapprocher/écarter les mors l’un de l’autre entraîne sa translation par rapport à la première partie 11 de la base 10 et permet de solliciter les mors 13, lesquels pivotent par rapport à la deuxième partie 12 de la base 10, autour d’organes de fixation 26 qui permettent d’assujettir les mors 13 à la deuxième partie 12 de la base 10 au niveau de leur première extrémité respective 20. The rotation of the mechanism 15 configured to bring the jaws closer / apart from one another causes its translation relative to the first part 11 of the base 10 and makes it possible to apply the jaws 13, which pivot relative to the second part 12 of the base 10, around fasteners 26 which make it possible to subject the jaws 13 to the second part 12 of the base 10 at their respective first end 20.
Les organes de fixation 26 sont ici formés par des goupilles qui traversent chacune la deuxième partie 12 de la base 10 et un mors 13 respectif dans sa largeur. The fixing members 26 are here formed by pins which each pass through the second part 12 of the base 10 and a respective jaw 13 in its width.
Le mécanise 15 configuré pour rapprocher/écarter les mors 13 l’un de l’autre est ici pourvu d’une tige de montage 27 traversant un orifice 28 ménagé dans le première partie 11 de la base 10 et configurée pour être insérée dans un embout de montage complémentaire de la perche 7. A une première extrémité de cette tige 27, le mécanise 15 comporte un écrou de transmission de mouvement 29 configuré pour être actionné depuis la perche 7. The mechanism 15 configured to bring the jaws 13 closer to / apart from one another is here provided with a mounting rod 27 passing through an orifice 28 formed in the first part 11 of the base 10 and configured to be inserted into a tip assembly of the pole 7. At a first end of this rod 27, the mechanism 15 comprises a movement transmission nut 29 configured to be actuated from the pole 7.
A une seconde extrémité de cette tige 27, opposée à sa première extrémité, le mécanise 15 comporte un embout d’extrémité 30 ayant au moins une paroi en rampe 31 qui coopère avec la face interne 21 des mors 13 au niveau de leur première extrémité 20 respective. At a second end of this rod 27, opposite its first end, the mechanism 15 comprises an end piece 30 having at least one ramp wall 31 which cooperates with the internal face 21 of the jaws 13 at their first end 20. respective.
Dans l’exemple illustré et comme visible notamment sur les figures 3 et 6, l’embout d’extrémité 30 est conique et relié mécaniquement à l’écrou de transmission de mouvement 29 au travers de la tige 27. La base 10 est pourvue aussi, sur sa première partie 11, d’une patte de fixation 32 pourvue d’un organe de verrouillage, par exemple à encliquetage, configuré pour coopérer avec un organe de verrouillage complémentaire de la perche 7, de sorte à assurer la fixation du dispositif 6 au bout de la perche 7. In the example illustrated and as visible in particular in Figures 3 and 6, the end piece 30 is conical and mechanically connected to the movement transmission nut 29 through the rod 27. The base 10 is also provided , on its first part 11, a fixing lug 32 provided with a locking member, for example a snap-fit, configured to cooperate with a complementary locking member of the pole 7, so as to ensure the fixing of the device 6 at the end of the pole 7.
La base 10 est également pourvue, sur sa première partie 11 , d’une patte de connexion 33 sur laquelle est assujettie mécaniquement et connectée électriquement le câble de mise à la terre 8. The base 10 is also provided, on its first part 11, with a connection tab 33 on which the grounding cable 8 is mechanically secured and electrically connected.
Pour l’interconnexion du dispositif 6 avec le premier conducteur électrique 2 logé dans l’armoire électrique 1 en vue de sa mise à la terre, le procédé comporte les étapes ci-dessous. Le dispositif 6 est emmanché au bout de la perche 7 par l’intermédiaire de sa tige de montage 27. Si le dispositif 6 se trouve dans sa configuration d’insertion (ou de relâchement), il est laissé dans cette configuration. For the interconnection of the device 6 with the first electrical conductor 2 housed in the electrical cabinet 1 with a view to its earthing, the method comprises the steps below. The device 6 is fitted at the end of the pole 7 via its mounting rod 27. If the device 6 is in its insertion (or release) configuration, it is left in this configuration.
Dans la négative, le dispositif 6 est passé de sa configuration d’enserrement vers sa configuration d’insertion (ou de relâchement) par l’actionnement du mécanisme 15 pour écarter les mors 13, par exemple au moyen d’un mécanisme complémentaire que comporte la perche 7 et qui est couplé mécaniquement au mécanisme 15 du dispositif 6. If not, the device 6 is passed from its gripping configuration to its insertion (or release) configuration by actuating the mechanism 15 to move the jaws 13 apart, for example by means of a complementary mechanism that includes the pole 7 and which is mechanically coupled to the mechanism 15 of the device 6.
On notera que l’organe de rappel 17 facilite l’écartement des mors 13 et le renvoi du dispositif 6 dans sa configuration d’insertion (ou de relâchement). Note that the return member 17 facilitates the separation of the jaws 13 and the return of the device 6 in its insertion (or release) configuration.
Le dispositif 6 est passé au travers de l’ouverture d’accès 9 de l’armoire électrique 1 et introduit, dans sa configuration d’insertion, à l’intérieur de l’armoire électrique 1 jusqu’à recevoir le second conducteur électrique 3 entre les mors 13 dans le second logement proximal 24 et le premier conducteur électrique à interconnecter pour sa mise à la terre entre les mors 13 dans le premier logement distal 23. The device 6 is passed through the access opening 9 of the electrical cabinet 1 and introduced, in its insertion configuration, inside the electrical cabinet 1 until it receives the second electrical conductor 3. between the jaws 13 in the second proximal housing 24 and the first electrical conductor to be interconnected for its grounding between the jaws 13 in the first distal housing 23.
Le mécanisme 15 est ensuite actionné, par exemple via la perche 7, pour rapprocher les mors 13 et ainsi passer le dispositif 6 de sa configuration d’insertion à sa configuration d’enserrement dans laquelle il enserre au moins partiellement le premier conducteur électrique 2 pour son interconnexion électrique et sa mise à la terre via les mors 13, les câblettes 14, la première partie 11 de la base 10, la patte de connexion 33 et le câble de mise à la terre 8. The mechanism 15 is then actuated, for example via the pole 7, to bring the jaws 13 together and thus pass the device 6 from its insertion configuration to its clamping configuration in which it at least partially encloses the first electrical conductor 2 for its electrical interconnection and its grounding via the jaws 13, the cables 14, the first part 11 of the base 10, the connection tab 33 and the grounding cable 8.
Dans cette configuration d’enserrement du dispositif 6, le second conducteur électrique 3 n’est pas interconnecté électriquement ni mis à la terre. In this configuration of the clamping device 6, the second electrical conductor 3 is not electrically interconnected or earthed.
Le dispositif 6 permet, grâce à la configuration de son système à deux mors 13, d’établir une interconnexion électrique avec le premier conducteur électrique 2 en vue de mise à la terre et qui se trouve ici juste derrière le second conducteur électrique 3 qui ne doit pas être interconnecté. The device 6 allows, thanks to the configuration of its two-jaw system 13, to establish an electrical interconnection with the first electrical conductor 2 with a view to earthing and which is here just behind the second electrical conductor 3 which does not must not be interconnected.
En d’autres termes, grâce au système à deux mors 13 du dispositif 6 et en particulier grâce à la forme des deux mors 13, il est possible d’interconnecter le premier conducteur électrique 2 en vue de sa mise à la terre, sans que le second conducteur 3 qui se trouve juste devant et qui ne doit pas être interconnecté ne vienne gêner l’interconnexion du premier conducteur électrique 2 se trouvant juste derrière. In other words, thanks to the two-jaw system 13 of the device 6 and in particular thanks to the shape of the two jaws 13, it is possible to interconnect the first electrical conductor 2 with a view to its earthing, without the second conductor 3 which is just in front and which must not being interconnected does not interfere with the interconnection of the first electrical conductor 2 located just behind.
Les figures 9 à 12 montre une variante de réalisation du dispositif d’interconnexion électrique en configuration d’enserrement, avec les premier et second conducteurs électriques pris dans le dispositif et de manière isolée l’un des mors de ce dispositif. Figures 9 to 12 show an alternative embodiment of the electrical interconnection device in a clamping configuration, with the first and second electrical conductors taken from the device and in isolation one of the jaws of this device.
Dans ce dispositif, seuls les mors diffèrent de ceux visibles sur les figures 2 à 8. In this device, only the jaws differ from those visible in Figures 2 to 8.
Pour simplifier la description, les mêmes références numériques ont donc été utilisées sauf pour les mors pour lesquels des références similaires mais additionnées du nombre 100 ont été utilisées. To simplify the description, the same numerical references were therefore used except for the jaws for which similar references but added to the number 100 were used.
Dans ce dispositif 6, les mors 113 s’étendent longitudinalement et sont assujettis par la première extrémité 120 à la deuxième partie 12 de la base 10. In this device 6, the jaws 113 extend longitudinally and are secured by the first end 120 to the second part 12 of the base 10.
Les mors 113 présentent ici des faces internes 121 qui sont pourvues de cavités 140 définissant au moins partiellement le second logement proximal 124 dans la zone de réception 116, et des portions d’extrémités recourbées vers l’intérieur 122 définissant au moins partiellement le premier logement distal 23. The jaws 113 here have internal faces 121 which are provided with cavities 140 at least partially defining the second proximal housing 124 in the receiving zone 116, and end portions curved inwardly 122 defining at least partially the first housing distal 23.
Les mors 113 présentent également des protubérances 145, en forme de bourrelets, ménagées en saillie des faces internes 121 entre les cavités 140 et les portions d’extrémités recourbées 122 et délimitant sensiblement le premier logement distal 123 du second logement proximal 124. The jaws 113 also have protuberances 145, in the form of beads, protruding from the internal faces 121 between the cavities 140 and the curved end portions 122 and substantially delimiting the first distal housing 123 of the second proximal housing 124.
Ainsi, les mors 113 peuvent être plus courts que les mors 13. Thus, the jaws 113 can be shorter than the jaws 13.
Les câblettes 14 sont fixées chacune par une première extrémité 18 sur la surface externe 135 d’un des mors 113 et par une deuxième extrémité 19 opposée à la première extrémité 18 à la deuxième partie 12 de la base 10. The cables 14 are each fixed by a first end 18 on the outer surface 135 of one of the jaws 113 and by a second end 19 opposite the first end 18 to the second part 12 of the base 10.
L’organe de rappel 17 est interposé entre les mors 113 et logé dans les sièges 125 ménagés en saillie des faces internes 121 des mors 113. The return member 17 is interposed between the jaws 113 and housed in the seats 125 provided projecting from the internal faces 121 of the jaws 113.
Les premier et deuxième conducteurs électriques 2 et 3 sont reçus dans la zone de réception 116, avec le premier conducteur électrique 2 qui est reçu dans le premier logement distal 123 pour son interconnexion et sa mise à la terre, tandis que le second conducteur électrique 3 est reçu dans le second logement proximal 124. The first and second electrical conductors 2 and 3 are received in the reception area 116, with the first electrical conductor 2 which is received in the first distal housing 123 for its interconnection and updating. earth, while the second electrical conductor 3 is received in the second proximal housing 124.
Ainsi, le premier conducteur électrique 2 se trouve à l’extrémité proximale du dispositif 6, le second conducteur électrique 3 se trouve entre le premier conducteur électrique 2 et la base 10, et l’organe de rappel se trouve ici entre le second conducteur électrique 3 et la base 10. Thus, the first electrical conductor 2 is located at the proximal end of the device 6, the second electrical conductor 3 is located between the first electrical conductor 2 and the base 10, and the return member is located here between the second electrical conductor. 3 and base 10.
Sur les figures 10 et 11 , le dispositif 6 se trouve dans sa configuration d’enserrement dans laquelle les mors 113 enserrent partiellement le premier conducteur électrique 2 dans le premier logement distal 123 de sorte à assurer une interconnexion électrique entre le premier conducteur électrique 2 et les mors 113 ; tandis que les mors 113 n’enserrent pas le second conducteur électrique 3 dans le second logement proximal 124. In Figures 10 and 11, the device 6 is in its clamping configuration in which the jaws 113 partially surround the first electrical conductor 2 in the first distal housing 123 so as to provide an electrical interconnection between the first electrical conductor 2 and the jaws 113; while the jaws 113 do not enclose the second electrical conductor 3 in the second proximal housing 124.
Ici, le premier conducteur électrique 2 a une section assez similaire à celle du second conducteur électrique 3, voire même un peu inférieure. Here, the first electrical conductor 2 has a section quite similar to that of the second electrical conductor 3, or even a little smaller.
Ceci est possible grâce au dimensionnement des mors 113 du dispositif 6, notamment de la profondeur des cavités 140, vis-à-vis des sections des conducteurs qui peuvent être reçus dans la zone de réception 116 et plus particulièrement dans les espaces définis respectivement par le premier logement distal 123 et le second logement proximal 124. This is possible thanks to the dimensioning of the jaws 113 of the device 6, in particular the depth of the cavities 140, with respect to the sections of the conductors which can be received in the reception zone 116 and more particularly in the spaces defined respectively by the first distal housing 123 and second proximal housing 124.
Le mécanise 15 configuré pour rapprocher/écarter les mors 113 l’un de l’autre et la base 10 sont identiques à ceux décrits en référence au dispositif illustré sur les figures 2 à 6. The mechanism 15 configured to bring the jaws 113 closer to each other and the base 10 are identical to those described with reference to the device illustrated in Figures 2 to 6.
Le procédé d’interconnexion électrique est lui aussi identique à celui décrit en référence au dispositif illustré sur les figures 2 à 6. The electrical interconnection method is also identical to that described with reference to the device illustrated in Figures 2 to 6.
Des variantes non illustrées sont décrites ci-dessous. Variants not shown are described below.
Le dispositif peut comporter plus de deux logements pour recevoir des conducteurs électriques. Par exemple, le dispositif peut être configuré pour délimiter entre les mors plusieurs logements pour des conducteurs à interconnecter, avec éventuellement des conducteurs les précédents ou étant interposés et qui ne sont pas à interconnecter ; ou bien plusieurs logements pour des conducteurs à ne pas interconnecter disposés du côté proximal et un ou plusieurs logements pour conducteurs à interconnecter disposés du côté distal. The device may have more than two housings for receiving electrical conductors. For example, the device can be configured to define between the jaws several housings for conductors to be interconnected, possibly with conductors preceding them or being interposed and which are not to be interconnected; or several housings for conductors not to be interconnected arranged on the proximal side and a or more housings for conductors to be interconnected arranged on the distal side.
Les mors peuvent être pourvus d’une pluralité de cavités, voire d’une portion avec cavité et d’une portion sensiblement droite et rectiligne sur la même face interne. The jaws can be provided with a plurality of cavities, or even a portion with a cavity and a substantially straight and rectilinear portion on the same internal face.
D’autres formes de cavités peuvent être envisagées, par exemple en triangle, en U, ou bien d’autres formes plutôt qu’une forme arrondie. Other shapes of cavities can be considered, for example triangle, U, or other shapes rather than a rounded shape.
La câblette peut cheminer à l’intérieur de la base plutôt qu’à l’extérieur. The cable can run inside the base rather than outside.
L’organe de liaison électrique peut être formé d’une lamelle métallique ou de plusieurs lamelles métalliques, plutôt que d’une câblette, et courir le long de l’un au moins des mors et cheminer à l’intérieur ou à l’extérieur de la base. The electrical connection member can be formed from a metal strip or several metal strips, rather than a cable, and run along at least one of the jaws and run inside or outside from the base.
Le dispositif peut ne pas être monté sur une perche mais plutôt être utilisé directement et manuellement par un opérateur. Il comporte alors un organe de préhension. The device may not be mounted on a pole but rather be used directly and manually by an operator. It then comprises a gripping member.
L’embout d’extrémité du mécanisme peut présenter une forme différente d’un cône, par exemple une forme en triangle, en pyramide etc. The end cap of the mechanism may have a shape other than a cone, such as a triangle, pyramid, etc.
La base peut être formée en une seule pièce et être dépourvue d’une deuxième partie orientable. The base can be formed in one piece and not have a second swiveling part.
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.
