Description

La présente invention concerne appareil électrique du type bloc de jonction destiné à la connexion d'un appareil basse tension.The present invention relates to electrical terminal block type apparatus for connecting a low voltage device.

Il est connu du document FR2913533 d'utiliser un appareil électrique du type bloc de jonction, comportant

  • un corps isolant,
  • un pied de fixation relié à une partie arrière du corps isolant et destiné à fixer l'appareil électrique sur un support,
  • une barrette conductrice, reçue dans le corps isolant, et agencée pour réaliser une connexion électrique avec une borne de connexion disposée sur une paroi frontale de l'appareil électrique,
  • un organe élastique de connexion pouvant être connecté à une barre collectrice, ladite barre collectrice pouvant être maintenue dans une position de connexion par rapport au support, ledit organe élastique de connexion comportant d'une part au moins une partie élastique mobile sous l'action de la barre collectrice, et étant d'autre part mobile en translation dans un logement du corps isolant entre une première position dite ouverte dans laquelle la barre collectrice disposée dans la position de connexion n'est pas reliée électriquement à la borne de connexion, et une seconde position dite fermée dans laquelle la barre collectrice disposée dans la position de connexion est reliée électriquement à la borne de connexion.
It is known from the document FR2913533 to use an electrical apparatus of the terminal block type, comprising
  • an insulating body,
  • a fixing foot connected to a rear part of the insulating body and intended to fix the electrical apparatus on a support,
  • a conductive strip, received in the insulating body, and arranged to make an electrical connection with a connection terminal disposed on a front wall of the electrical apparatus,
  • a resilient connection member connectable to a bus bar, said bus bar being able to be held in a connection position with respect to the support, said elastic connection member having on the one hand at least one elastic portion movable under the action of the collector bar, and on the other hand being movable in translation in a housing of the insulating body between a first so-called open position in which the busbar arranged in the connection position is not electrically connected to the connection terminal, and a second so-called closed position in which the busbar disposed in the connection position is electrically connected to the connection terminal.

De plus, l'appareil électrique comporte un curseur mobile disposé dans un emplacement ménagé sur la paroi frontale de l'appareil électrique et relié mécaniquement à l'organe élastique de connexion de manière à commander le mouvement de translation de l'organe élastique de connexion.In addition, the electrical apparatus comprises a movable slider arranged in a location on the front wall of the electrical apparatus and mechanically connected to the elastic connection member so as to control the translational movement of the elastic connection member. .

Le support est destiné à maintenir un ensemble d'appareils électrique disposant chacun de plusieurs bornes de connexion dans lesquelles viennent se connecter les bornes d'un ou plusieurs autres appareils électrique.The support is intended to maintain a set of electrical devices each having several connection terminals in which are connected the terminals of one or more other electrical devices.

Cette barre collectrice confère à ces bornes un même potentiel électrique.This busbar gives these terminals the same electrical potential.

Néanmoins, lors de l'insertion ou du retrait d'un appareil électrique sur son ou de son support, l'organe élastique de connexion dudit appareil électrique peut subir des contraintes indésirables pouvant aboutir à une déformation plastique de l'organe élastique de connexion.Nevertheless, when inserting or removing an electrical device on its or its support, the elastic member of connection of said apparatus electric can undergo undesirable stresses may result in plastic deformation of the elastic connection member.

Cette déformation plastique conduit à une déterioration de la qualité de connexion, notamment par la création de faux contacts entre l'organe élastique de connexion et la barre collectrice.This plastic deformation leads to a deterioration of the quality of connection, in particular by the creation of false contacts between the elastic connection member and the busbar.

Plusieurs situations capables de générer de telles contraintes ont été identifiées, notamment :

  • un angle d'approche trop grand lors de l'insertion de l'appareil électrique sur son support,
  • un mauvais centrage de l'appareil électrique sur son support,
  • une insertion ou un retrait de l'appareil électrique de son support alors que l'organe de connexion est dans sa position fermée.
Several situations capable of generating such constraints have been identified, including:
  • an approach angle that is too large when inserting the electrical device on its support,
  • improper centering of the electrical device on its support,
  • an insertion or withdrawal of the electrical device from its support while the connection member is in its closed position.

La borne de terre 9 est reliée électriquement au pied de fixation 3 réalisé en matériau conducteur, lui-même relié électriquement au rail support 50 également en matériau conducteur.The earth terminal 9 is electrically connected to the fixing foot 3 made of conductive material, itself electrically connected to the support rail 50 also made of conductive material.

Le rail support 50 est relié électriquement à la terre.The support rail 50 is electrically connected to the ground.

La borne de phase 8 est destinée à être reliée électriquement à l'aide d'une barrete conductrice (non illustrée) disposée dans le corps isolant 2 à une borne de connexion 16 disposée sur une partie distale du corps isolant 2 et destinée à la connexion du fil de phase d'un réseau d'alimentation ou d'un peigne électrique d'alimentation destiné à relier électriquement les différentes bornes de phase 8 d'un ensemble d'appareils électriques 1 montés sur le rail support 50.The phase terminal 8 is intended to be electrically connected by means of a conductive bar (not shown) disposed in the insulating body 2 to a connection terminal 16 disposed on a distal portion of the insulating body 2 and intended for connection phase wire of a power supply network or an electric supply comb for electrically connecting the different phase terminals 8 of a set of electrical devices 1 mounted on the support rail 50.

La borne de neutre 7 est quant à elle destinée à être reliée électriquement à l'aide de la barrete conductrice 6 à une barre collectrice ou barre de neutre 40 destinée à relier électriquement les différentes bornes de neutre 7 d'un ensemble d'appareils électriques 1 montés sur le rail support 50.The neutral terminal 7 is itself intended to be electrically connected by means of the conductive bar 6 to a bus bar or neutral bar 40 intended to electrically connect the different neutral terminals 7 of a set of electrical appliances. 1 mounted on the support rail 50.

Dans ces conditions, la barre de neutre 40 occupe une position de connexion déterminée par rapport au rail support 50 pouvant être par exemple conférée par le maintien de ladite barre de neutre 40 par au moins deux appareils électriques 1 accrochés sur ledit rail support 50.Under these conditions, the neutral bar 40 occupies a given connection position with respect to the support rail 50 which can be for example conferred by the holding of said neutral bar 40 by at least two electrical devices 1 hooked on said support rail 50.

L'appareil électrique 1 comprend en outre un organe élastique de connexion 10 à la barre de neutre 40, mobile en translation dans un logement 17 du corps isolant 2 entre une première position P1 dite ouverte dans laquelle la barre de neutre 40 dans sa position de connexion déterminée n'est pas reliée électriquement à la borne de connexion, et une seconde position P2 dite fermée dans laquelle la barre de neutre 40 dans sa position de connexion déterminée est reliée électriquement à la borne de neutre 7.The electrical apparatus 1 further comprises a resilient connecting member 10 to the neutral bar 40, movable in translation in a housing 17 of the insulating body 2 between a first open position P1 in which the neutral bar 40 in its position of determined connection is not electrically connected to the connection terminal, and a second so-called closed position P2 in which the neutral bar 40 in its determined connection position is electrically connected to the neutral terminal 7.

En outre, l'appareil électrique 1 comprend un curseur mobile 30 disposé dans un emplacement 31 ménagé sur la paroi frontale 5 de l'appareil électrique 1 et relié mécaniquement à l'organe élastique de connexion 10 de manière à commander le mouvement de translation de l'organe élastique de connexion 10. Les moyens employés à cet effet sont décrits plus loin dans le texte.In addition, the electrical apparatus 1 comprises a movable slider 30 disposed in a location 31 formed on the front wall 5 of the electrical apparatus 1 and mechanically connected to the elastic connection member 10 so as to control the translational movement of the the elastic connection member 10. The means used for this purpose are described later in the text.

Afin de réaliser le contact électrique avec la barre de neutre 40 dans sa position fermée P2, l'organe élastique de connexion 10 comprend deux parties ou branches élastiques 11, 12 s'étendant en majeure partie selon deux plans sensiblement parallèles.In order to make the electrical contact with the neutral bar 40 in its closed position P2, the elastic connection member 10 comprises two parts or elastic branches 11, 12 extending for the most part in two substantially parallel planes.

La première branche 11 comporte une première extrémité libre 14a orientée vers l'extérieur du corps isolant 2, et la deuxième branche 12 comporte une extrémité libre 13 orientée également vers l'extérieur du corps isolant 2.The first branch 11 has a first free end 14a facing outwardly of the insulating body 2, and the second branch 12 has a free end 13 also facing outwardly of the insulating body 2.

La première extrémité libre 14a de la première barnche 11 et l'extrémité libre 13 de la deuxième branche 12 sont toutes deux mobiles et agencées pour réaliser le contact électrique avec la barre de neutre 40 dans la position fermée P2 de l'organe élastique de connexion 10.The first free end 14a of the first barnche 11 and the free end 13 of the second branch 12 are both movable and arranged to make electrical contact with the neutral bar 40 in the closed position P2 of the elastic connection member 10.

Le mouvement de la première extrémité libre 14a de la première branche 11 et de l'extrémité libre 13 de la deuxième branche 12 est décrit plus loin dans le texte.The movement of the first free end 14a of the first branch 11 and the free end 13 of the second branch 12 is described later in the text.

La première branche 11 comporte en outre une deuxième extrémité libre 14b mobile agencée pour réaliser le contact électrique avec la barrette conductrice 6 et pour former avec une portion de la barrette conductrice 6, un moyen de maintien en position 32 de l'organe élastique de connexion 10 dans sa position fermée P2 et avantageusement également dans sa position ouverte P1.The first branch 11 further comprises a second mobile free end 14b arranged to make electrical contact with the conductive strip 6 and to form with a portion of the conductive strip 6, a means for holding the elastic connection member in position 32 10 in its closed position P2 and advantageously also in its open position P1.

Les deux branches 11, 12 contribuent également à assurer le maintien mécanique de l'organe élastique de connexion 10 sur la barre de neutre 40 dans la position fermée P2.The two branches 11, 12 also contribute to ensuring the mechanical retention of the elastic connection member 10 on the neutral bar 40 in the closed position P2.

A cet effet, mais également en vue d'assurer une bonne qualité du contact électrique, l'extrémité libre 14a mobile de la première branche 11 et l'extrémité libre 13 mobile de la deuxième branche 12 définissent une zone de rétrécissement 18 comprenant un écart entre les deux branches 11, 12 inférieur à l'épaisseur e de la barre de neutre 40 et mettant en regard l'une de l'autre une face de connexion 29 de chacune des branches 11, 12 agencée pour réaliser le contact électrique avec la barre de neutre 40.For this purpose, but also with a view to ensuring a good quality of the electrical contact, the free end 14a of the first movable branch 11 and the free end 13 of the second branch 12 define a narrowing zone 18 comprising a gap between the two branches 11, 12 less than the thickness e of the neutral bar 40 and facing one another a connection face 29 of each of the branches 11, 12 arranged to make the electrical contact with the neutral bar 40.

Ainsi, lors de l'introduction de l'organe élastique de connexion 10 dans la barre de neutre 40, chacune des branches 11, 22 subie une déformation entrainant le déplacement de chacune des branches 11, 12 et en particulier de leur extrémités respectives 14a, 13 selon une direction sensiblement transversale à la direction d'introduction de la barre de neutre 40, en prenant l'organe élastique de connexion 10 comme référentiel.Thus, during the introduction of the elastic connection member 10 in the neutral bar 40, each of the branches 11, 22 undergoes a deformation causing the displacement of each of the branches 11, 12 and in particular their respective ends 14a, 13 in a direction substantially transverse to the insertion direction of the neutral bar 40, by taking the elastic connection member 10 as a reference.

Les deux branches élastiques 11, 12 sont reliées par un corps 19 s'étendant en majeure partie sensiblement selon un plan transversal à ceux dans lesquels s'étendent en majeure partie les branches élastiques 11, 12.The two elastic branches 11, 12 are connected by a body 19 extending for the most part substantially along a plane transverse to those in which the elastic branches 11, 12 extend for the most part.

Ce corps 19 joignant les deux branches 11, 12 est réalisé en matériau conducteur permettant ainsi à la deuxième branche 12 de contribuer à l'établissement d'une liaison électrique entre la barre de neutre 40 et la borne de neutre 7.This body 19 joining the two branches 11, 12 is made of conductive material thus allowing the second branch 12 to contribute to the establishment of an electrical connection between the neutral bar 40 and the neutral terminal 7.

Comme illustré aux figures 5 à 7, le corps 19 est disposé de manière excentrée par rapport aux deux branches 11, 12 de manière à les maintenir par l'un de leur flanc.As illustrated in Figures 5 to 7 , the body 19 is arranged eccentrically with respect to the two branches 11, 12 so as to maintain them by one of their flank.

Sur la zone de raccordement entre le corps 19 et la deuxième branche 13, une ouverture traverssante 15 est ménagée pour permettre l'insertion d'une portion du curseur 30 de manière à assurer un lien mécanique permettant l'entraînement en translation de l'organe élastique de connexion 10 par le curseur 30.On the connection zone between the body 19 and the second branch 13, a through opening 15 is provided to allow the insertion of a portion of the slider 30 so as to provide a mechanical link allowing the drive in translation of the organ elastic connection 10 by the cursor 30.

En particulier, cette ouverture 15 est placée de manière à permettre le déplacement en translation du curseur 30 dans son emplacement 31 du corps isolant 2 depuis une première position amenant l'organe élastique de connexion 10 vers sa position ouverte P1 jusqu'à une position amenant l'organe élastique de connexion 10 vers sa position fermée P2.In particular, this opening 15 is placed so as to allow the displacement in translation of the slider 30 in its location 31 of the insulating body 2 from a first position bringing the elastic connection member 10 to its open position P1 to a position causing the elastic connection member 10 to its closed position P2.

Selon un aspect essentiel de l'invention, l'appareil électrique 1 comporte en outre un organe d'appui mobile 20 pour la barre collectrice 40 comportant au moins une portion d'appui 21, 22 pour la barre collectrice 40 agencée pour restreindre la mobilité de l'au moins une partie élastique 11, 12 de l'organe élastique de connexion 10 en position fermée ou au voisinage de cette position.According to an essential aspect of the invention, the electrical apparatus 1 further comprises a movable support member 20 for the busbar 40 having at least one bearing portion 21, 22 for the busbar 40 arranged to restrict mobility the at least one elastic portion 11, 12 of the elastic connection member 10 in the closed position or in the vicinity of this position.

Dans le mode de réalisation présenté, l'organe d'appui mobile 20 est agencé pour suivre le mouvement de translation de l'organe élastique de connexion 10 et est réalisé en une seule pièce avec l'organe élastique de connexion 10.In the embodiment shown, the mobile support member 20 is arranged to follow the translational movement of the elastic connection member 10 and is made in one piece with the elastic connection member 10.

Cet organe d'appui 20 est disposé sur l'extrémité du corps 19 orientée en direction des extrémités libres 14a, 13 respectivement des branches 11, 12 de l'organe élastique de connexion 10.This support member 20 is disposed on the end of the body 19 oriented in the direction of the free ends 14a, 13 respectively of the branches 11, 12 of the elastic connection member 10.

Bien entendu, l'organe d'appui 20 pourrait être réalisé indépendamment de l'organe élastique de connexion 10 puis relié à celui-ci sans pour autant sortir du cadre de l'invention.Of course, the support member 20 could be made independently of the elastic connection member 10 and then connected thereto without departing from the scope of the invention.

De même, dans un autre mode de réalisation (non illustré), le mouvement de l'organe d'appui 20 pourrait être indépendant du mouvement de l'organe élastique de connexion 10.Similarly, in another embodiment (not shown), the movement of the support member 20 could be independent of the movement of the elastic connection member 10.

Dans ce cas, le mouvement de l'organe d'appui 20 serait par exemple engendré sous l'action de la barre de neutre 40 et ramené vers une position de repos sous l'action d'un moyen de rappel, tel un ressort disposé dans le corps isolant 2.In this case, the movement of the support member 20 would for example be generated under the action of the neutral bar 40 and returned to a rest position under the action of a return means, such as a spring arranged in the insulating body 2.

Dans le mode de réalisation présenté, l'organe d'appui mobile 20 comprend un corps 25 à partir duquel s'étendent respectivement longitudinalement aux extrémités libres 14a, 13 respectivement des branches 11, 12, une première portion d'appui 21 et une deuxième portion d'appui 22 définissant un logement 28 pour la barre de neutre 40 entre ces deux portions d'appui 21, 22 et conférant à l'organe d'appui 20 une forme générale en « U » dont l'ouverture est disposé en regard de la barre de neutre 40 lorsque celle-ci est dans sa position de connexion déterminée et que l'appareil électrique 1 est accroché sur son rail support 50.In the embodiment shown, the movable support member 20 comprises a body 25 from which extend respectively longitudinally to the free ends 14a, 13 respectively of the branches 11, 12, a first support portion 21 and a second support portion 22 defining a housing 28 for the neutral bar 40 between these two support portions 21, 22 and giving the support member 20 a general shape "U" whose opening is arranged opposite of the neutral bar 40 when the latter is in its determined connection position and the electrical apparatus 1 is hooked on its support rail 50.

Le corps 25 de l'organe d'appui mobile 20 représentant la base de la forme en « U », comprend une face intérieure 26 s'étendant selon un plan sensiblement transversal à ceux dans lesquels s'étendent les deux branches 11, 12 ainsi qu'à celui dans lequel s'étend le corps 19 de l'organe élastique de connexion 10.The body 25 of the movable support member 20 representing the base of the "U" shape, comprises an inner face 26 extending in a plane substantially transverse to those in which the two branches 11, 12 and than that in which extends the body 19 of the elastic connection member 10.

En outre, cette face intérieure 26 est positionnée de manière à venir en butée de la barre de neutre 40 lorsque celle-ci est dans sa position de connexion déterminée et que l'organe élastique de connexion 10 se trouve dans sa position fermée P2. Les risques de faux contact sont ainsi davantage diminués.In addition, this inner face 26 is positioned to abut the neutral bar 40 when the latter is in its determined connection position and the elastic connection member 10 is in its closed position P2. The risk of false contact is thus further reduced.

La première portion d'appui 21 est plus éloignée de la face frontale 5 de l'appareil électrique 1 que la deuxième portion d'appui 22.The first support portion 21 is further away from the front face 5 of the electrical appliance 1 than the second support portion 22.

Ces deux portions d'appui 21, 22 s'étendent transversalement à la face intérieure 26 du corps 25 sur une distance s'arrêtant sensiblement à la zone de rétrécissement 18 précédemment définie par les extrémités 14a, 13 des deux branches 11, 12 de l'organe élastique de connexion 10.These two bearing portions 21, 22 extend transversely to the inner face 26 of the body 25 over a distance substantially stopping at the narrowing zone 18 previously defined by the ends 14a, 13 of the two branches 11, 12 of the elastic connection member 10.

De plus, ces deux portions d'appui 21, 22 comprennent chacune respectivement une rampe de guidage 23, 24 orientée de manière à favoriser l'introduction dans le logement 28 de la barre de neutre 40 entre les deux portions d'appui 21, 22.In addition, these two bearing portions 21, 22 each respectively comprise a guide ramp 23, 24 oriented so as to promote the introduction into the housing 28 of the neutral bar 40 between the two bearing portions 21, 22 .

Dans le mode de réalisation présenté, chacune des portions d'appui 21, 22 est agencée pour restreindre respectivement la mobilité de chacune des branches élastiques 11, 12 et en particulier de ses extrémités respectives 14a, 13 de l'organe élastique de connexion à partir d'une position déterminée limite de chacune des extrémités 14a, 13 des branches élastiques 11, 12.In the embodiment shown, each of the support portions 21, 22 is arranged to restrict respectively the mobility of each of the elastic branches 11, 12 and in particular of its ends. respective 14a, 13 of the elastic connection member from a specific predetermined position of each of the ends 14a, 13 of the elastic branches 11, 12.

Ainsi, si au cours du passage de la position ouverte P1 vers la position fermée P2 de l'organe élastique de connexion 10, l'appareil électrique 1 présente un mauvais centrage sur son rail support 50 ou bien si au cours d'une insertion ou d'un retrait de l'appareil électrique 1 de son rail support 50 alors que l'organe de connexion 10 est dans sa position fermée P2, alors le mouvement de la première branche 11 dans un sens de déplacement allant de la face de connexion 28 à la face opposée à la face de connexion de la première branche 11 sera limité par l'appui de la barre de neutre 40 sur la première portion d'appui 21 depuis sa rampe de guidage 23 jusqu'au contact avec la face intérieure 26 de l'organe d'appui 20.Thus, if during the passage from the open position P1 to the closed position P2 of the elastic connection member 10, the electrical apparatus 1 has a bad centering on its support rail 50 or if during an insertion or a withdrawal of the electrical apparatus 1 from its support rail 50 while the connection member 10 is in its closed position P2, then the movement of the first branch 11 in a direction of movement from the connection face 28 at the face opposite the connection face of the first branch 11 will be limited by the support of the neutral bar 40 on the first bearing portion 21 from its guide ramp 23 to contact with the inner face 26 of the support member 20.

De la même façon, le mouvement de la deuxième branche 12 dans un sens de déplacement opposé à la première branche 11 sera limité par l'appui de la barre de neutre 40 sur la deuxième portion d'appui 22 depuis sa rampe de guidage 24 jusqu'au contact avec la face intérieure 26 de l'organe d'appui 20.In the same way, the movement of the second branch 12 in a direction of displacement opposite to the first branch 11 will be limited by the support of the neutral bar 40 on the second support portion 22 from its guide ramp 24 until in contact with the inner face 26 of the support member 20.

De plus, si l'appareil électrique 1 est inséré avec un angle d'approche trop grand lors de l'insertion sur son rail support 50, et ce que l'organe élastique de connexion 10 soit dans sa position ouverte P1 ou fermée P2, alors le mouvement de la première branche 11 dans un sens de déplacement allant de la face opposé à la face de connexion 28 vers la face de connexion 28 de la première branche 11 sera limité par l'appui de la barre de neutre 40 sur la première portion d'appui 21 en particulier sur sa face opposée à la rampe de guidage 23.In addition, if the electrical apparatus 1 is inserted with an approach angle too large when inserted on its support rail 50, and the elastic connection member 10 is in its open position P1 or closed P2, then the movement of the first leg 11 in a direction of movement from the opposite side to the connection face 28 to the connection face 28 of the first leg 11 will be limited by the support of the neutral bar 40 on the first bearing portion 21 in particular on its face opposite to the guide ramp 23.

Afin de limiter cet angle d'approche, le corps isolant 2 comprend des moyens de guidage 33 permettant un prépositionnement de l'appareil électrique 1 par rapport à la barre de neutre 40 lors de son insertion sur son rail support 50.In order to limit this angle of approach, the insulating body 2 comprises guiding means 33 enabling the electrical apparatus 1 to be prepositioned with respect to the neutral bar 40 when it is inserted on its support rail 50.

Bien que l'invention ait été décrite en liaison avec des exemples particuliers de réalisation, il est bien évident qu'elle n'y est nullement limitée et qu'elle comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons.Although the invention has been described in connection with particular embodiments, it is obvious that it is not limited thereto and that it includes all the technical equivalents of the means described and their combinations.

C'est ainsi que la longueur des portions d'appui 21, 22 peut aller au-delà de la zone de rétrécissement 18 définie par les extrémités 14a, 13 des deux branches 11, 12 de même que dans sa position fermée P2, il n'est pas forcément nécessaire que la barre de neutre 40 vienne au contact de la face intérieure 26 de l'organe d'appui mobile 20.Thus, the length of the bearing portions 21, 22 can go beyond the narrowing zone 18 defined by the ends 14a, 13 of the two branches 11, 12 as in its closed position P2, it is not necessarily necessary that the neutral bar 40 comes into contact with the inner face 26 of the movable support member 20.
