D'autres fonctions peuvent être requises de la part d'un bloc de jonction. En particulier, il peut être conçu de sorte à permettre la mise en place d'un cavalier de shunt permettant d'établir un contact électrique entre deux barrettes de liaison implantées respectivement dans deux blocs de jonctions différents. En particulier, ces deux blocs de jonction peuvent être montés de manière adjacente sur un même rail de support.Other functions may be required from a terminal block. In particular, it can be designed to allow the establishment of a shunt jumper for establishing an electrical contact between two connecting bars respectively implanted in two different junction blocks. In particular, these two terminal blocks can be mounted adjacent to one and the same support rail.

La mise en place du cavalier de shunt se pratique par insertion de celui-ci, au niveau de chaque bloc de jonction, dans un puits de shunt ménagé dans le boitier isolant.The implementation of the shunt jumper is practiced by inserting it, at each terminal block, into a shunt well in the insulating housing.

Il existe une problématique de pouvoir identifier le(s) bloc(s) de jonction de manière simple, efficace, pratique et économique. En effet, il est nécessaire de pouvoir repérer et identifier la fonction du bloc de jonction ou de chaque étage, ou bien la fonction générale recherchée.There is a problem of being able to identify the block (s) of junction in a simple, effective, practical and economical way. Indeed, it is necessary to identify and identify the function of the terminal block or each floor, or the general function sought.

A l'image de la solution décrite dans le document DE202009003250U1 , il est connu de prévoir un porte-étiquette commun aux différents blocs de jonction alignés côte à côte sur une même rangée. Mais ce type de porte-repère collectif est peu pratique et toute intervention sur les blocs de jonction nécessite une opération sur le porte-repère, ce qui introduit des risques d'erreurs de manipulation et de repérage, au-delà du côté fastidieux de la manoeuvre.Like the solution described in the document DE202009003250U1 it is known to provide a common label holder to the different terminal blocks aligned side by side on the same row. But this type of collective marker-holder is impractical and any intervention on the terminal blocks requires an operation on the marker-holder, which introduces risks of mishandling and misregistration, beyond the tedious side of the maneuver.

De manière alternative, il est connu d'équiper chaque bloc de jonction avec un porte-repère individuel. Une solution de cette nature est décrite par exemple dans le document DE2020080136609U1 ou dans le document DE102008058871B3 .Alternatively, it is known to equip each terminal block with an individual marker holder. A solution of this nature is described for example in the document DE2020080136609U1 or in the document DE102008058871B3 .

Toutefois, les solutions actuellement connues ne donnent pas une entière satisfaction. D'abord, la fixation du porte-repère nécessite l'aménagement d'une zone dédiée à cette fonction et/ou réclame des moyens de fixation dédiés au montage du porte-repère sur le boitier isolant, ce qui grève l'encombrement général et le coût. D'autre part, les solutions connues restent complexes, onéreuses et peu pratiques.However, the currently known solutions do not give complete satisfaction. First, the fixing of the marker carrier requires the development of an area dedicated to this function and / or requires fixing means dedicated to mounting the marker holder on the insulating housing, which causes the overall size and the cost. On the other hand, the known solutions remain complex, expensive and impractical.

La présente invention vise à résoudre tout ou partie des inconvénients listés ci-dessus.The present invention aims to solve all or part of the disadvantages listed above.

Il est également proposé un bloc de jonction électrique comprenant un boitier isolant ayant une face arrière équipée d'éléments de fixation permettant de fixer le bloc de jonction sur un rail de support selon un agencement dans lequel une pluralité de blocs de jonction sont disposés côte à côte sur une même rangée orientée suivant la direction du rail de support et une face avant comprenant au moins un puits de shunt, le bloc de jonction comprenant un tel porte-repère dont la première partie de fixation est insérée dans le puits de shunt.There is also provided an electrical terminal block comprising an insulating housing having a rear face provided with fixing elements for fixing the terminal block on a support rail according to an arrangement in which a plurality of terminal blocks are arranged side by side. coast on the same row oriented in the direction of the support rail and a front face comprising at least one shunt well, the terminal block comprising such a marker holder whose first fixing portion is inserted into the shunt well.

Selon un autre mode de réalisation, le puits de shunt comprend une nervure annulaire interne aménagée au niveau de son embouchure vers la face avant et comprise dans un plan perpendiculaire à la direction suivant laquelle la première partie de fixation est insérée dans le puits de shunt et la première partie de fixation comprend une gorge annulaire externe dans laquelle la nervure annulaire interne du puits de shunt vient s'insérer par emboîtement élastique durant l'insertion de la première partie de fixation.According to another embodiment, the shunt well comprises an internal annular rib arranged at its mouth towards the front face and included in a plane perpendicular to the direction in which the first attachment portion is inserted into the shunt well and the first fixing portion comprises an outer annular groove in which the inner annular rib of the shunt well is inserted by resilient engagement during the insertion of the first fixing portion.

Il est également proposé un agencement comprenant un rail de support et au moins deux tels blocs de jonction fixés par leurs faces arrières de sorte à être disposés côte à côte sur une même rangée orientée selon la direction du rail de support, agencement dans lequel le porte-repère fixé dans le puits de shunt du boitier isolant de l'un des blocs de jonction est indépendant du porte-repère fixé dans le puits de shunt du boitier isolant de l'autre des blocs de jonction.It is also proposed an arrangement comprising a support rail and at least two such terminal blocks fixed by their rear faces so as to be arranged side by side on the same row oriented in the direction of the support rail, arrangement in which the door -repère fixed in the shunt well of the insulating housing of one of the terminal blocks is independent of the marker holder fixed in the shunt well of the insulating housing of the other terminal blocks.

L'invention sera bien comprise à l'aide de la description qui suit de modes particuliers de réalisation de l'invention donnés à titre d'exemples non limitatifs et représentés sur les dessins annexés, dans lesquels :

  • Les Figures 1 à 3 montrent un exemple de porte-repère selon un aspect de l'invention, dans une position abaissée de sa deuxième partie d'identification.
  • Les Figures 4 à 6 montrent le porte-repère des Figures 1 à 3 dans une position relevée de sa deuxième partie d'identification.
  • Les Figures 7 et 8 montrent un exemple de bloc de jonction selon un autre aspect de l'invention, le porte-repère des Figures 1 à 6 étant fixé sur le boitier isolant.
The invention will be better understood from the following description of particular embodiments of the invention given by way of non-limiting example and shown in the accompanying drawings, in which:
  • The Figures 1 to 3 show an exemplary marker holder according to one aspect of the invention, in a lowered position of its second identification part.
  • The Figures 4 to 6 show the benchmark of Figures 1 to 3 in a raised position of its second identification part.
  • The Figures 7 and 8 show an example of a terminal block according to another aspect of the invention, the reference carrier of the Figures 1 to 6 being fixed on the insulating case.

Les Figures 1 à 6 annexées telles que présentées sommairement ci-dessus montrent un exemple de porte-repère individuel 10 selon un aspect de l'invention, destiné à être monté de manière démontable sur un boitier électriquement isolant 12 d'un bloc de jonction 11 électrique également connu sous le nom de « terminal block » en terminologie anglo-saxonne.The Figures 1 to 6 appended as summarily presented above show an example of an individual marker holder 10 according to one aspect of the invention, to be removably mounted on an electrically insulating housing 12 of an electrical terminal block 11 also known as the name of "terminal block" in English terminology.

Par « individuel », il est compris que le porte-repère 10 est tel qu'il équipe individuellement un seul bloc de jonction 11 et permet d'identifier au moins une fonction destinée à être remplie par le bloc de jonction 11 sur lequel il est fixé. Autrement dit, le porte-repère 10 n'identifie que les fonctions remplies par ce bloc de jonction 11.By "individual" it is understood that the marker holder 10 is such that it individually equips a single terminal block 11 and makes it possible to identify at least one function intended to be filled by the terminal block 11 on which it is fixed. In other words, the marker-holder 10 only identifies the functions fulfilled by this terminal block 11.

Les Figures 7 et 8 annexées montrent également un exemple de bloc de jonction 11 électrique selon un autre aspect de l'invention, le porte-repère 10 des Figures 1 à 6 étant fixé sur le boitier isolant 12 d'une manière particulière qui sera décrite plus loin.The Figures 7 and 8 annexed also show an example of electric terminal block 11 according to another aspect of the invention, the marker-holder 10 of the Figures 1 to 6 being fixed on the insulating housing 12 in a particular manner which will be described later.

En référence aux Figures 7 et 8, le bloc de jonction 11 est un appareil électrique comprenant au moins deux bornes de connexion 13 permettant chacune de connecter un conducteur électrique (non représenté) correspondant, par exemple sous la forme d'un fil électriquement conducteur. Le bloc de jonction 11 comprend aussi au moins une barrette de liaison 14 électriquement conductrice pour établir la liaison électrique entre les deux conducteurs électriques connectés aux deux bornes de connexion 13.With reference to Figures 7 and 8 , the terminal block 11 is an electrical apparatus comprising at least two connection terminals 13 each permitting connecting a corresponding electrical conductor (not shown), for example in the form of an electrically conductive wire. The terminal block 11 also comprises at least one electrically conductive connecting strip 14 for establishing the electrical connection between the two electrical conductors connected to the two connection terminals 13.

La réunion des deux bornes de connexion 13 et de la barrette de liaison 14 constitue un étage. La variante illustrée sur les Figures 7 et 8 est un bloc de jonction 11 à un seul étage, mais le bloc de jonction 11 pourrait indifféremment comporter deux ou trois étages, en fonction des applications associées au bloc de jonction 11 et en fonction des besoins des utilisateurs.The meeting of the two connection terminals 13 and the connecting strip 14 constitutes a stage. The variant illustrated on Figures 7 and 8 is a single-stage terminal block 11, but the terminal block 11 could indifferently comprise two or three stages, depending on the applications associated with the terminal block 11 and according to the needs of the users.

Comme indiqué précédemment, le bloc de jonction 11 comprend donc le boitier isolant 12 évoqué ci-dessus, dans lequel sont montées les deux bornes de connexion 13 et la (les) barrette(s) de liaison 14 électriquement conductrice(s). Chaque borne de connexion 13 peut être d'une nature quelconque, par exemple utilisant une fixation par vis ou par ressort de contact, ou bien de type auto-dénudant.As indicated above, the terminal block 11 therefore comprises the insulating housing 12 mentioned above, in which are mounted the two connection terminals 13 and the (the) strip (s) electrically conductive connection (s) 14. Each connection terminal 13 may be of any kind, for example using a fastening screw or contact spring, or self-stripping type.

Le boitier isolant 12 possède une face arrière 15 équipée d'éléments de fixation 16 permettant de fixer le bloc de jonction 11 sur un rail de support (non représenté) selon un agencement dans lequel une pluralité de blocs de jonction 11 sont disposés côte à côte sur une même rangée orientée suivant le rail de support. Les éléments de fixation 16 peuvent coopérer avec le rail de support selon un principe d'encliquetage ou d'emboîtement élastique.The insulating housing 12 has a rear face 15 equipped with fastening elements 16 for fixing the terminal block 11 on a support rail (not shown) in an arrangement in which a plurality of terminal blocks 11 are arranged side by side. on the same row oriented along the support rail. The fastening elements 16 can cooperate with the support rail according to a principle of snap or elastic interlocking.

D'ailleurs, un autre aspect de l'invention concerne un agencement comprenant le rail de support et au moins deux blocs de jonction 11 tels que décrits ici, autrement dit une pluralité de tels blocs de jonction 11, fixés par leurs faces arrières de sorte à être disposés côte à côte sur une même rangée orientée selon la direction du rail de support. Il est entendu que le nombre de blocs de jonction 11 peut être supérieur ou égal à 2.Moreover, another aspect of the invention relates to an arrangement comprising the support rail and at least two terminal blocks 11 as described herein, that is to say a plurality of such terminal blocks 11, fixed by their rear faces so to be arranged side by side on the same row oriented in the direction of the support rail. It is understood that the number of terminal blocks 11 may be greater than or equal to 2.

Pour une bonne compréhension de l'organisation spatiale, un repère orthonormé est associé au boitier isolant 12. La direction X correspond à la direction du boitier isolant 12 qui est orientée dans le sens de la longueur du rail de support lorsque le bloc de jonction 11 est fixé sur le rail de support. La dimension du boitier isolant 12 selon la direction X correspond à son épaisseur. La direction Y correspond à la direction du boitier isolant 12 qui est orientée dans le sens de la largeur du rail de support lorsque le bloc de jonction 11 est fixé sur le rail de support. La dimension du boitier isolant 12 selon la direction Y correspond à sa longueur. La direction Z correspond à la direction du boitier isolant 12 qui est localement perpendiculaire à la paroi où est fixé le rail de support lorsque le bloc de jonction 11 est fixé sur le rail de support. La dimension du boitier isolant 12 selon la direction Z correspond à sa hauteur. La hauteur et la longueur du boitier isolant 12 sont sensiblement égales entre elles tandis que l'épaisseur est nettement inférieure à la hauteur et à la longueur.For a good understanding of the spatial organization, an orthonormal reference is associated with the insulating housing 12. The direction X corresponds to the direction of the insulating housing 12 which is oriented in the direction of the length of the support rail when the terminal block 11 is attached to the support rail. The size of the insulating housing 12 in the X direction corresponds to its thickness. Y direction corresponds to the direction of the insulating housing 12 which is oriented in the width direction of the support rail when the terminal block 11 is fixed on the support rail. The size of the insulating housing 12 along the Y direction corresponds to its length. Z direction corresponds to the direction of the insulating housing 12 which is locally perpendicular to the wall where is fixed the support rail when the terminal block 11 is fixed on the support rail. The size of the insulating housing 12 in the Z direction corresponds to its height. The height and length of the insulating housing 12 are substantially equal to each other while the thickness is significantly less than the height and length.

Le boitier isolant 12 comprend également une face avant 17 comprenant au moins un puits de shunt 18. Le nombre de puits de shunt 18 peut être supérieur ou égal à 1, en fonction des applications et des besoins des utilisateurs du bloc de jonction 11. A titre d'exemple non limitatif, la variante illustrée comprend deux puits de shunt 18. Les deux puits de shunt 18 sont décalés l'un par rapport à l'autre suivant la longueur du boitier isolant 11 qui est comptée selon la direction Y. Chaque puits de shunt 18 s'étend suivant la direction Z. Les faces arrière et avant 15, 17 sont opposées suivant la direction Z.The insulating housing 12 also comprises a front face 17 comprising at least one shunt well 18. The number of shunt wells 18 may be greater than or equal to 1, depending on the applications and the needs of the users of the terminal block 11. A As a non-limiting example, the illustrated variant comprises two shunt wells 18. The two shunt wells 18 are offset relative to each other along the length of the insulating housing 11 which is counted in the Y direction. shunt well 18 extends in the Z direction. The rear and front faces 15, 17 are opposite in the Z direction.

Le porte-repère 10 comprend une première partie de fixation 19 configurée de sorte à pouvoir être fixée dans la face avant 17 du boitier isolant 12 du bloc de jonction 11. Notamment, la première partie de fixation 19 est configurée de sorte que sa fixation sur la face avant 17 du boitier isolant 12 se pratique par une insertion dans l'un des puits de shunt 18 ménagés dans la face avant 17 du boitier isolant 12 du bloc de jonction 11.The marker holder 10 comprises a first fixing portion 19 configured so as to be fixed in the front face 17 of the insulating housing 12 of the terminal block 11. In particular, the first fixing portion 19 is configured so that its fixing on the front face 17 of the insulating housing 12 is made by insertion into one of the shunt wells 18 formed in the front face 17 of the insulating housing 12 of the terminal block 11.

Le bloc de jonction 11 comprend donc un tel porte-repère 10 dont la première partie de fixation 19 est fixée dans la face avant 17 du boitier isolant 12. Notamment, la première partie de fixation 19 est insérée dans l'un des puits de shunt 18 ménagés dans la face avant 17 du boitier isolant 12.The terminal block 11 thus comprises such a marker-holder 10, the first fixing portion 19 of which is fixed in the front face 17 of the insulating housing 12. In particular, the first fixing portion 19 is inserted into one of the shunt wells. 18 formed in the front face 17 of the insulating housing 12.

Par « puits de shunt », il est entendu une ouverture ménagée dans le boitier isolant 12 de sorte à permettre une communication entre l'intérieur et l'extérieur du boitier isolant 12 et configurée pour permettre la mise en place dans cette ouverture d'un élément de shunt (non représenté), autrement connu sous le nom de cavalier de shunt. L'élément de shunt vient s'insérer dans deux puits de shunt 18 appartenant à deux blocs de jonction 11 adjacents au sein de la rangée de blocs 11 montés sur le rail de support. La mise en place de l'élément de shunt dans les puits de shunt 18 des deux blocs de jonction 11 adjacents permet d'établir un contact électrique entre deux barrettes de liaison 14 implantées respectivement à l'intérieur des boitiers isolants 12 des deux blocs de jonction 11 adjacents.By "shunt well", it is understood an opening in the insulating housing 12 so as to allow communication between the inside and the outside of the insulating housing 12 and configured to allow the introduction into this opening of a shunt element (not shown), otherwise known as a shunt jumper. The shunt element is inserted into two shunt wells 18 belonging to two adjacent terminal blocks 11 within the row of blocks 11 mounted on the support rail. The introduction of the shunt element in the shunt wells 18 of the two adjacent terminal blocks 11 makes it possible to establish an electrical contact between two connecting bars 14 respectively implanted inside the insulating housings 12 of the two blocks of junction 11 adjacent.

Le porte-repère 10 comprend une deuxième partie d'identification 20 articulée par rapport à la première partie de fixation 19. La deuxième partie d'identification 20 peut donc être mobile par pivotement par rapport au boitier isolant 12 lorsque la première partie de fixation 19 est fixée dans le puits de shunt 18 du boitier isolant 12.The marker-holder 10 comprises a second identification part articulated with respect to the first fastener part. The second identification part can therefore be movable by pivoting with respect to the case. insulation 12 when the first fixing portion 19 is fixed in the shunt well 18 of the insulating housing 12.

La deuxième partie d'identification 20 comprend au moins une portion d'identification 21. L'axe de pivotement D1 conféré par l'articulation de la deuxième partie d'identification 20 par rapport à la première partie de fixation 19 est situé à une extrémité de la deuxième partie d'identification 20 et est sensiblement aligné avec ladite au moins une portion d'identification 21. Autrement dit, ladite au moins une portion d'identification 21 est décalée par rapport à l'axe de pivotement D1 selon une direction perpendiculaire à la direction de l'axe de pivotement D1. Par « sensiblement aligné », on entend « exactement aligné » ou « aligné dans une tolérance donnée », cette tolérance donnée pouvant être une tolérance angulaire ou une tolérance dimensionnelle comptées dans le plan perpendiculaire à l'axe de pivotement D1. Notamment, l'angle formé, dans le plan perpendiculaire à l'axe de pivotement D1, entre la portion d'identification 21 et la droite rejoignant l'axe D1 et la portion d'identification 21 admet une tolérance angulaire de 20°, en ce sens que cet angle est égal à 180° à 20° près, restant donc inclus dans une plage variant entre 160° et 200°. Alternativement, il peut être admis que, vu dans le plan perpendiculaire à l'axe de pivotement D1, la position de l'axe D1 par rapport à l'orientation générale de la portion d'identification 21 admet une tolérance dimensionnelle de 5 mm, en ce sens que la position de l'axe D1 peut être située exactement le long de l'orientation générale de la portion d'identification 21 ou présenter un décalage vers le haut ou vers le bas par rapport à l'orientation générale de la portion d'identification ayant une valeur incluse dans une plage variant entre 0 et 5 mm.The second identification part 20 comprises at least one identification portion 21. The pivot axis D1 imparted by the articulation of the second identification part 20 with respect to the first fixing portion 19 is located at one end. of the second identification part 20 and is substantially aligned with said at least one identification portion 21. In other words, said at least one identification portion 21 is offset with respect to the pivot axis D1 in a perpendicular direction to the direction of the pivot axis D1. By "substantially aligned" is meant "exactly aligned" or "aligned within a given tolerance", this tolerance may be an angular tolerance or a dimensional tolerance counted in the plane perpendicular to the pivot axis D1. In particular, the angle formed, in the plane perpendicular to the pivot axis D1, between the identification portion 21 and the straight line joining the axis D1 and the identification portion 21 has an angular tolerance of 20 °, in this sense that this angle is equal to 180 ° to 20 °, so remaining in a range between 160 ° and 200 °. Alternatively, it can be admitted that, seen in the plane perpendicular to the pivot axis D1, the position of the axis D1 with respect to the general orientation of the identification portion 21 has a dimensional tolerance of 5 mm, in that the position of the axis D1 can be located exactly along the general orientation of the identification portion 21 or have a shift up or down with respect to the general orientation of the portion identification having a value included in a range between 0 and 5 mm.

La portion d'identification 21 peut présenter une partie sensiblement plane et l'axe de pivotement D1 est agencé sensiblement dans le prolongement de cette partie plane. Autrement dit, l'axe de pivotement D1 est sensiblement contenu dans un plan prolongeant la partie plane de la portion d'identification 21 et est décalé par rapport à la portion d'identification 21 dans ledit plan. Par « sensiblement contenu », on entend les mêmes tolérances que celles décrites dans le paragraphe précédent : en particulier, l'axe de pivotement D1 peut être situé exactement dans le plan prolongeant la partie plane de la portion d'identification 21 ou être décalé vers le haut ou vers le bas, par rapport au plan prolongeant la partie plane de la portion d'identification 21, selon une valeur incluse entre 0 et 5 mm.The identification portion 21 may have a substantially flat portion and the pivot axis D1 is arranged substantially in the extension of this flat portion. In other words, the pivot axis D1 is substantially contained in a plane extending the flat portion of the identification portion 21 and is offset with respect to the identification portion 21 in said plane. By "substantially contained" means the same tolerances as those described in the preceding paragraph: in particular, the pivot axis D1 may be located exactly in the plane extending the flat portion of the identification portion 21 or be shifted to up or down, relative to the plane extending the flat portion of the identification portion 21, with a value between 0 and 5 mm.

Selon un mode de réalisation, la deuxième partie d'identification 20 comprend un levier allongé s'étendant selon une direction principale d'extension, correspondant à sa direction de plus grande longueur. L'axe de pivotement D1 et ladite au moins une portion d'identification 21 sont décalés l'un par rapport à l'autre selon la direction principale d'extension du levier allongé. L'axe de pivotement D1 est agencé à une extrémité du levier allongé, cette extrémité étant considérée dans la direction principale. Chaque portion d'identification 21 est par exemple ménagée dans une face supérieure 22 du levier allongé. Le mouvement d'articulation de la deuxième partie d'identification 20 correspond à un pivotement du levier allongé autour de l'axe de pivotement D1, la direction principale d'extension du levier allongé présentant donc une orientation variable autour de l'axe de pivotement D1 en même temps que le pivotement du levier allongé.According to one embodiment, the second identifying portion 20 comprises an elongate lever extending in a main direction of extension, corresponding to its direction of greater length. The pivot axis D1 and said at least one identification portion 21 are offset relative to each other in the main direction of extension of the elongated lever. The pivot axis D1 is arranged at one end of the elongated lever, this end being considered in the main direction. Each identification portion 21 is for example formed in an upper face 22 of the elongate lever. The hinge movement of the second identification part 20 corresponds to a pivoting of the elongated lever around the pivot axis D1, the main extension direction of the elongate lever thus having a variable orientation around the pivot axis D1 at the same time as the pivoting of the elongated lever.

Dans un mode de réalisation particulier non limitatif, la deuxième partie d'identification 20 est munie d'une pluralité de portions d'identification 21 alignées entre elles, c'est-à-dire décalées deux à deux le long d'une même et unique direction D2. L'articulation de la deuxième partie d'identification 20 par rapport à la première partie de fixation 19 est sensiblement située dans le prolongement, selon la direction D2, de l'alignement des portions d'identification 21 entre elles. Par « sensiblement situé dans le prolongement », on entend les mêmes tolérances que celles décrites précédemment en lien avec les termes « sensiblement aligné » et « sensiblement contenu ».In a particular non-limiting embodiment, the second identification part 20 is provided with a plurality of identification portions 21 aligned with each other, that is to say shifted two by two along the same and single direction D2. The articulation of the second identifying portion 20 with respect to the first fixing portion 19 is substantially located in the extension, in the direction D2, of the alignment of the identification portions 21 between them. "Substantially located in the extension" means the same tolerances as those previously described in relation to the terms "substantially aligned" and "substantially contained".

Ainsi, les différentes portions d'identification 21 sont décalées entre elles selon la même direction D2 que la direction suivant laquelle chaque portion d'identification 21 est décalée par rapport à l'axe de pivotement D1.Thus, the different identification portions 21 are offset between them in the same direction D2 as the direction in which each identification portion 21 is offset with respect to the pivot axis D1.

Dans l'exemple illustré, la deuxième partie d'identification 20 comprend par exemple deux portions d'identification 21, décalées entre elles le long de la direction principale d'extension du levier allongé. La direction principale d'extension du levier allongé correspond à la direction D2 le long de laquelle les portions d'identification 21 sont échelonnées. Chacune de ces deux portions d'identification 21 est décalée par rapport à l'axe de pivotement D1 suivant la direction principale d'extension du levier allongé, c'est-à-dire également suivant la direction D2.In the illustrated example, the second identification part 20 comprises for example two identification portions 21, offset with respect to each other along the main direction of extension of the elongated lever. The main direction of extension of the elongated lever corresponds to the direction D2 along which the identification portions 21 are staggered. Each of these two identification portions 21 is offset with respect to the pivot axis D1 along the main direction of extension of the elongated lever, that is to say also in the direction D2.

Comme cela est illustré, chaque portion d'identification 21 est par exemple configurée pour recevoir un repère d'identification (non représenté). A titre d'exemple, chaque portion d'identification 21 se présente sous la forme d'une fente d'insertion du repère d'identification dans laquelle le repère d'identification est inséré par un mouvement de coulissement perpendiculaire à la direction D2.As illustrated, each identification portion 21 is for example configured to receive an identification mark (not shown). By way of example, each identification portion 21 is in the form of an insertion slot of the identification mark in which the identification mark is inserted by a sliding movement perpendicular to the direction D2.

L'axe de pivotement D1 de la deuxième partie d'identification 20 par rapport à la première partie de fixation 19 est perpendiculaire à la direction D3 suivant laquelle la première partie de fixation 19 est destinée à être insérée dans le puits de shunt 18. La direction D3 est orientée parallèlement à la direction Z.The pivot axis D1 of the second identification part 20 with respect to the first fixing portion 19 is perpendicular to the direction D3 according to which the first attachment portion 19 is intended to be inserted into the shunt well 18. The direction D3 is oriented parallel to the direction Z.

Dans la variante qui est illustrée, la première partie de fixation 19 et la deuxième partie d'identification 20 sont constituées par deux pièces distinctes assemblées l'une avec l'autre par des éléments de solidarisation à pivotement permettant un pivotement de la deuxième partie d'identification 20 par rapport à la première partie de fixation 19 de sorte à constituer l'articulation entre la première partie de fixation 19 et la deuxième partie d'identification 20. Les éléments de solidarisation à pivotement sont de nature quelconque dès lors qu'ils remplissent la fonction présentée ici.In the variant which is illustrated, the first fastening portion 19 and the second identification portion 20 are constituted by two separate parts joined together by pivoting fastening elements allowing a pivoting of the second part of FIG. identification 20 with respect to the first fixing portion 19 so as to constitute the articulation between the first fastening portion 19 and the second identifying portion 20. The pivotally fastening elements are of any kind as soon as they fulfill the function presented here.

Les éléments de solidarisation à pivotement comprennent par exemple une partie tubulaire mâle 23 solidaire d'une extrémité de la première partie de fixation 19, cette extrémité étant considérée suivant la direction D3. L'axe de la partie tubulaire mâle 23 est orienté selon la direction X. Il est inséré suivant la direction Z par emboîtement élastique dans une cavité tubulaire 24 complémentaire, elle-même solidaire d'une extrémité de la deuxième partie d'identification 20, cette extrémité étant considérée suivant la direction D2. L'axe d'orientation de la cavité tubulaire 24 est également orienté suivant la direction X. La coopération entre la partie tubulaire mâle 23 avec la cavité tubulaire 24 constitue une liaison mécanique de type liaison pivot, dont l'axe de pivotement correspond à l'axe de pivotement D1 précité. L'axe de pivotement D1 est donc orienté parallèlement à la direction X.The pivotally fastening elements comprise for example a male tubular portion 23 secured to one end of the first fixing portion 19, this end being considered in the direction D3. The axis of the male tubular part 23 is oriented in the X direction. It is inserted in the Z direction by elastic interlocking in a complementary tubular cavity 24, itself secured to one end of the second identification part 20. this end being considered in the direction D2. The axis of orientation of the tubular cavity 24 is also oriented in the X direction. The cooperation between the male tubular part 23 and the tubular cavity 24 constitutes a mechanical connection of the pivot connection type, the pivot axis of which corresponds to pivot axis D1 above. The pivot axis D1 is therefore oriented parallel to the direction X.

Il est toutefois envisageable de prévoir une organisation inversée, en rendant la partie tubulaire mâle 23 solidaire de la deuxième partie d'identification 20 et en rendant la cavité tubulaire 24 solidaire de la première partie de fixation 19.However, it is conceivable to provide an inverted organization, making the male tubular portion 23 integral with the second identification part 20 and making the tubular cavity 24 integral with the first fixing portion 19.

Il reste également possible, dans une version alternative à celle décrite ci-dessus, que la première partie de fixation 19 et la deuxième partie d'identification 20 soient formées dans une seule et même pièce monobloc, l'articulation entre la première partie de fixation 19 et la deuxième partie d'identification 20 étant dans ce cas constituée par une zone localement déformable élastiquement de cette pièce monobloc. Cette zone localement déformable peut être obtenue par une modification locale de matière et/ou par une réduction locale d'une dimension adoptée par la matière. La capacité de déformation élastique résultera d'un compromis entre la facilité de pivotement et la résistance mécanique évitant une rupture de cette zone sous charge.It is also possible, in an alternative version to that described above, that the first fixing portion 19 and the second identification portion 20 are formed in one and the same piece, the articulation between the first fixing portion 19 and the second identification portion 20 being in this case constituted by a locally elastically deformable zone of this one-piece piece. This locally deformable zone can be obtained by a local modification of material and / or by a local reduction of a dimension adopted by the material. The capacity of elastic deformation will result from a compromise between the ease of pivoting and the mechanical resistance avoiding a rupture of this zone under load.

L'axe de pivotement D1 de la deuxième partie d'identification 20 par rapport à la première partie de fixation 19 est également perpendiculaire à la direction D2 suivant laquelle les portions d'identification 21 sont échelonnées le long de la deuxième partie d'identification 20. La direction D2 est mobile par rotation dans le plan (Y, Z).The pivot axis D1 of the second identification part 20 with respect to the first attachment portion 19 is also perpendicular to the direction D2 according to which the identification portions 21 are staggered along the second identification part 20. The direction D2 is rotatable in the plane (Y, Z).

Par le montage décrit précédemment, la deuxième partie d'identification 20 varie avantageusement au moins entre une position angulaire abaissée (Figure 7) par rapport au boitier isolant 12 dans laquelle la deuxième partie d'identification 20 est sensiblement parallèle à la face avant 17 du boitier isolant 12 et une position angulaire redressée (Figure 8) dans laquelle la deuxième partie d'identification 20 est sensiblement perpendiculaire localement à la face avant 17 du boitier isolant 12. La première partie de fixation 19 du porte-repère 10 est immobile par rapport au boitier isolant 12 durant le changement de position angulaire de la deuxième partie d'identification 20 du porte-repère 10. Les Figures 1 à 3 montrent la position occupée par la deuxième partie d'identification 20 par rapport à la première partie de fixation 19 lorsque la deuxième partie d'identification 20 est apte à occuper sa position angulaire abaissée. A l'inverse, les Figures 4 à 6 montrent la position occupée par la deuxième partie d'identification 20 par rapport à la première partie de fixation 19 lorsque la deuxième partie d'identification 20 est apte à occuper sa position angulaire redressée. La position angulaire redressée est adoptée par la deuxième partie d'identification 20 lorsque l'accès aux ouvertures 29 qui donnent accès aux bornes de connexion 13 et dans lesquelles les conducteurs électriques sont insérés est nécessaire et/ou lorsque l'accès à l'autre puits de shunt 18 est nécessaire. Sinon, pour une facilité de lecture des données inscrites au niveau des portions d'identification et pour une diminution de l'encombrement, la position angulaire abaissée est normalement adoptée par la deuxième partie d'identification 20.By the assembly described above, the second identification part 20 advantageously varies at least between a lowered angular position ( Figure 7 ) relative to the insulating housing 12 in which the second identification portion 20 is substantially parallel to the front face 17 of the insulating housing 12 and a rectified angular position ( Figure 8 ) in which the second identification portion 20 is substantially perpendicular locally to the front face 17 of the insulating housing 12. The first fixing portion 19 of the marker carrier 10 is stationary relative to the insulating housing 12 during the change of angular position of the second identification part 20 of the marker-holder 10. The Figures 1 to 3 show the position occupied by the second identification part 20 with respect to the first attachment part 19 when the second identification part 20 is able to occupy its lowered angular position. Conversely, Figures 4 to 6 show the position occupied by the second identification part 20 with respect to the first fixing part 19 when the second identification part 20 is able to occupy its rectified angular position. The rectified angular position is adopted by the second identification part 20 when access to the openings 29 which give access to the connection terminals 13 and in which the electrical conductors are inserted is necessary and / or when the access to the other Shunt well 18 is needed. Otherwise, for ease of reading of the data entered at the level of the identification portions and for a reduction of the bulk, the lowered angular position is normally adopted by the second identification part 20.

Dans un mode de réalisation particulier, le porte-repère 10 comprend des éléments d'indexation angulaire de la position angulaire occupée par la deuxième partie d'identification 20 par rapport à la première partie de fixation 19, notamment selon des positions angulaires prédéterminées. Les éléments d'indexation angulaire sont par exemple constitués pour prédéterminer uniquement la position angulaire abaissée et la position angulaire relevée que la deuxième partie d'identification peut sélectivement occuper. Les éléments d'indexation angulaire peuvent également être conçus pour éventuellement prédéterminer une ou plusieurs position(s) angulaire(s) intermédiaire(s) entre les positions angulaires abaissée et redressée.In a particular embodiment, the marker holder 10 comprises angular indexing elements of the angular position occupied by the second identification portion 20 relative to the first fixing portion 19, in particular at predetermined angular positions. The angular indexing elements are for example constituted to predetermine only the lowered angular position and the raised angular position that the second identification part can selectively occupy. The angular indexing elements may also be designed to possibly predetermine one or more angular position (s) intermediate (s) between the lowered and rectified angular positions.

Les éléments d'indexation angulaire sont par exemple obtenus par des butées angulaires 25, 26 solidaires de la deuxième partie d'identification, agencées de sorte à limiter et borner la course angulaire maximale de la deuxième partie d'identification 20 autour de l'axe de pivotement D1. La butée 25 est utilisée (Figure 8) pour limiter et prédéterminer la position angulaire redressée de la deuxième partie d'identification 20. La butée 26 est au contraire utilisée (Figure 7) pour limiter et prédéterminer la position angulaire abaissée de la deuxième partie d'identification 20. Alternativement ou de manière combinée, les éléments d'indexation angulaire peuvent également comprendre une pluralité de fentes 27 ménagées sur la partie tubulaire mâle 23 et un ergot 28 solidaire de la cavité tubulaire 24 apte à venir s'insérer, dans chacune des positions prédéterminées souhaitées pour la deuxième partie d'identification 20, dans l'une correspondante des fentes 27 parmi la pluralité de fentes 27.The angular indexing elements are for example obtained by angular stops 25, 26 secured to the second identification part, arranged so as to limit and limit the maximum angular stroke of the second part. 20 around the pivot axis D1. The stop 25 is used ( Figure 8 ) to limit and predetermine the rectified angular position of the second identification part 20. The stop 26 is instead used ( Figure 7 ) to limit and predetermine the lowered angular position of the second identification part 20. Alternatively or in combination, the angular indexing elements may also comprise a plurality of slots 27 formed on the male tubular portion 23 and a lug 28 secured to of the tubular cavity 24 adapted to be inserted, in each of the predetermined positions desired for the second identification part 20, in a corresponding one of the slots 27 among the plurality of slots 27.

Selon un mode de réalisation particulier, la première partie de fixation 19 présente une symétrie selon un plan contenant à la fois la direction D3 selon laquelle la première partie de fixation 19 est destinée à être insérée dans le puits de shunt 18 et la direction correspondant à l'axe de pivotement D1 autour duquel la deuxième partie d'identification 20 est articulée par rapport à la première partie de fixation 19. Cette symétrie est organisée de sorte que le porte-repère 10 puisse occuper deux configurations différentes par rapport au boitier isolant 12, ces deux configurations variant l'une de l'autre par une rotation de 180 degrés de la première partie de fixation 19 autour de la direction D3 d'insertion dans le puits de shunt 18. Pour bien comprendre, le porte-repère 10 peut soit occuper la position représentée sur les Figures 7 et 8, soit une configuration inversée dans laquelle le porte-repère 10 serait retourné à 180° autour de la direction D3, prenant alors une position symétrique par rapport au plan (D1, D3), i.e. par rapport à un plan (X, Z) passant par D3. Lorsque le bloc de jonction 11 est fixé sur le rail de support, il est alors avantageusement possible de choisir l'orientation occupée par la deuxième partie d'identification 20 en position abaissée. Dans l'une des configurations angulaires que peut prendre la première partie de fixation 19 autour de la direction D3, la deuxième partie d'identification 20 occupant sa position abaissée s'étend vers le bas selon la direction Y. Dans l'autre des configurations angulaires que peut prendre la première partie de fixation 19 autour de la direction D3, la deuxième partie d'identification 20 occupant sa position abaissée s'étend vers le haut selon la direction Y.According to a particular embodiment, the first fixing portion 19 has a symmetry in a plane containing both the direction D3 according to which the first fixing portion 19 is intended to be inserted in the shunt well 18 and the direction corresponding to the pivot axis D1 around which the second identification portion 20 is articulated relative to the first fixing portion 19. This symmetry is organized so that the marker holder 10 can occupy two different configurations with respect to the insulating housing 12 , these two configurations varying from one another by a 180-degree rotation of the first fixing portion 19 around the insertion direction D3 in the shunt well 18. To understand, the marker-holder 10 can to occupy the position represented on the Figures 7 and 8 , an inverted configuration in which the marker carrier 10 would be turned 180 ° around the direction D3, then taking a symmetrical position with respect to the plane (D1, D3), ie with respect to a passing plane (X, Z) by D3. When the terminal block 11 is fixed on the support rail, it is then advantageously possible to choose the orientation occupied by the second identification part 20 in the lowered position. In one of the angular configurations that can take the first fixing portion 19 around the direction D3, the second identification portion 20 occupying its lowered position extends downwardly in the direction Y. In the other configurations angular that can take the first fixing portion 19 around the direction D3, the second identification portion 20 occupying its lowered position extends upwardly in the direction Y.

Le système d'insertion de la première partie de fixation 19 dans tout puits de shunt 18 du boitier isolant peut être de nature et de conception quelconques.The insertion system of the first fixing portion 19 in any shunt well 18 of the insulating housing may be of any type and design.

Notamment, le puits de shunt 18 peut comprendre une nervure annulaire interne 30 aménagée au niveau de son embouchure vers la face avant 17 et comprise dans un plan perpendiculaire à la direction D3 suivant laquelle la première partie de fixation 19 est insérée dans ce puits de shunt 18. La première partie de fixation 19 comprend une gorge annulaire externe 31 dans laquelle la nervure annulaire interne 30 du puits de shunt 18 vient s'insérer par emboîtement élastique durant l'insertion de la première partie de fixation 19.In particular, the shunt well 18 may comprise an internal annular rib 30 arranged at its mouth towards the front face 17 and included in a plane perpendicular to the direction D3 according to which the first fixing part 19 is inserted in this shunt well 18. The first fixing portion 19 comprises an outer annular groove 31 in which the inner annular rib 30 of the shunt well 18 is inserted by elastic interlocking during the insertion of the first fixing part 19.

Le puits de shunt 18 peut comprendre également un épaulement annulaire interne 32 se prolongeant par un alésage de réception 33 du côté opposé à l'embouchure du puits de shunt 18 sur la face avant 17 du boitier isolant 12. La première partie de fixation 19 comprend un tenon d'extrémité 34 élastiquement déformable venant s'insérer dans l'alésage de réception 33 durant l'insertion de la première partie de fixation 19 moyennant une déformation élastique du tenon d'extrémité 34. La déformation élastique du tenon d'extrémité 34 permet de compenser les variations de diamètre de l'alésage de réception 33 susceptibles d'apparaitre entre deux blocs de jonction 11 différents. De plus, la déformation élastique du tenon d'extrémité 34 supprime le porte-à-faux subi par le porte-repère 10 dans les différentes positions angulaires de la deuxième partie d'identification 20.The shunt well 18 may also include an inner annular shoulder 32 extending through a receiving bore 33 on the opposite side to the mouth of the shunt well 18 on the front face 17 of the insulating housing 12. The first attachment portion 19 comprises an elastically deformable end pin 34 inserted into the receiving bore 33 during the insertion of the first fixing portion 19 by elastic deformation of the end pin 34. The elastic deformation of the end pin 34 it makes it possible to compensate for variations in the diameter of the receiving bore 33 that may appear between two different junction blocks 11. In addition, the elastic deformation of the end post 34 removes the overhang undergone by the marker holder 10 in the different angular positions of the second identification part 20.

Avantageusement, la largeur de la deuxième partie de fixation 20 comptée suivant la direction suivant laquelle l'axe de pivotement D1 de la deuxième partie de fixation 20 par rapport à la première partie de fixation 19 est comptée est égale ou inférieure à l'épaisseur du boitier isolant 12 du bloc de jonction 11 comptée suivant la direction X suivant laquelle le rail de support est orienté lorsque le bloc de jonction 11 est fixé sur le rail de support.Advantageously, the width of the second fixing portion 20 counted in the direction in which the pivot axis D1 of the second fixing portion 20 relative to the first fixing portion 19 is counted is equal to or less than the thickness of the insulating housing 12 of the terminal block 11 counted in the X direction in which the support rail is oriented when the terminal block 11 is fixed on the support rail.

Au sein de l'agencement comprenant au moins deux blocs de jonction 11 positionnés côte-à-côte, le porte-repère 10 fixé dans la face avant 17 du boitier isolant 12 de l'un des blocs de jonction 11 est indépendant du porte-repère 10 fixé dans la face avant 17 du boitier isolant 12 de l'autre des blocs de jonction 11. Notamment, le porte-repère 11 fixé dans le puits de shunt 18 du boitier isolant 12 de l'un des blocs de jonction 11 est indépendant du porte-repère 10 fixé dans le puits de shunt 18 du boitier isolant 12 de l'autre des blocs de jonction 11. Cette indépendance se traduit par une possibilité de mouvement angulaire de la deuxième partie d'identification 20 et une possibilité de retrait de la première partie de fixation 19 hors du boitier isolant 12 indépendantes d'un porte-repère 10 à l'autre porte-repère 10.Within the arrangement comprising at least two terminal blocks 11 positioned side by side, the marker holder 10 fixed in the front face 17 of the insulating housing 12 of one of the terminal blocks 11 is independent of the carrier. reference 10 fixed in the front face 17 of the insulating housing 12 of the other terminal block 11. In particular, the marker holder 11 fixed in the shunt well 18 of the insulating housing 12 of one of the terminal blocks 11 is independent of the marker holder 10 fixed in the shunt well 18 of the insulating housing 12 of the other terminal block 11. This independence results in a possibility of angular movement of the second identification part 20 and a possibility of withdrawal of the first fixing portion 19 outside the insulating housing 12 independent of a marker-holder 10 to the other marker-holder 10.

De ce qui précède, il résulte que le porte-repère 10, le bloc de jonction 11 et l'agencement qui viennent d'être décrits proposent avantageusement une solution simple, économique, pratique et sécuritaire, efficace et peu encombrante.From the foregoing, it follows that the marker carrier 10, the terminal block 11 and the arrangement just described advantageously propose a simple solution, economical, practical and safe, efficient and compact.

Bien entendu, l'invention n'est évidemment pas limitée aux modes de réalisation représentés et décrits ci-avant, mais en couvre au contraire toutes les variantes.Of course, the invention is obviously not limited to the embodiments shown and described above, but covers all variants.
