L'invention concerne un module de raccordement électrique pour le verrouillage électrique entre un premier et un second contacteurs ainsi qu'un montage inverseur correspondant.The invention relates to an electrical connection module for electrically interlocking between a first and a second contactor and a corresponding inverter assembly.

Il est connu de réaliser un verrouillage mécanique par exemple par le document US 4 924 041 .It is known to achieve a mechanical locking for example by the document US 4,924,041 .

Les verrouillages électriques classiques de contacteurs sont réalisés par l'intermédiaire d'un câblage manuel par un opérateur. Lors de cette opération qui peut être longue à réaliser, une erreur de câblage est possible.Conventional contactor electrical interlocks are made through manual wiring by an operator. During this operation, which can take a long time to complete, a wiring error is possible.

La présente invention a pour but de palier à ces inconvénients en proposant un module destiné à réaliser un verrouillage électrique d'un premier et d'un second contacteurs ainsi qu'un montage correspondant pouvant être réalisé facilement et rapidement.The object of the present invention is to overcome these drawbacks by proposing a module for electrically interlocking a first and a second contactor as well as a corresponding arrangement that can be produced easily and quickly.

A cet effet, l'invention concerne un module de raccordement électrique entre un premier et un second contacteurs, caractérisé en ce qu'il comprend un corps comportant :

  • un premier et un second contacts auxiliaires normalement fermés, destinés respectivement à coopérer avec un coulisseau du premier et du second contacteurs,
  • une première et une seconde bornes de raccordement, destinées à coopérer avec un circuit extérieur en vue de l'alimentation de chacune des deux bobines,
  • un premier et un second éléments de connexion du module, destinés respectivement à coopérer avec un élément de connexion du premier et du second contacteurs,
la première borne de raccordement étant reliée en série au premier contact auxiliaire normalement fermé et au second élément de connexion du module, la seconde borne de raccordement étant reliée en série au second contact auxiliaire normalement fermé et au premier élément de connexion du module, et
les premier et second éléments de connexion du module étant positionnés sur une face du corps, respectivement au niveau d'une première et d'une seconde parties du module,
la première et la seconde parties du module étant respectivement destinées à être disposées sur la face avant du premier et du second contacteurs.For this purpose, the invention relates to an electrical connection module between a first and a second contactor, characterized in that it comprises a body comprising:

Les figures 3 et 4 décrivent un module amovible 10, destiné à être fixé et à coopérer avec deux contacteurs adjacents 1', 1 ".The Figures 3 and 4 describe a removable module 10, intended to be fixed and to cooperate with two adjacent contactors 1 ', 1 ".

Le module 10, de forme sensiblement parallélépipédique et allongée, comprend un corps 11 sur lequel est fixé un capot 12 par encliquetage.The module 10, of substantially parallelepipedal and elongate shape, comprises a body 11 on which is fixed a cover 12 by snapping.

Le module est divisé en deux parties latérales 13, 14 par rapport au plan médian P. Comme cela apparaîtra dans la suite de la description, chaque partie latérale 13, 14 comporte les mêmes éléments fonctionnels.The module is divided into two lateral parts 13, 14 with respect to the median plane P. As will be apparent in the following description, each lateral portion 13, 14 comprises the same functional elements.

Ainsi, chaque partie latérale 13, 14 du module amovible comporte une borne de raccordement 15, 16 en partie haute, et, en partie basse, une patte de fixation 17, 18 faisant saillie vers le bas, dont l'extrémité est recourbée vers l'intérieur, parallèlement à l'axe A du module.Thus, each lateral portion 13, 14 of the removable module has a connecting terminal 15, 16 at the top, and at the bottom, a bracket 17, 18 projecting downwards, whose end is bent towards the bottom. inside, parallel to the axis A of the module.

De même, chaque partie latérale 13, 14 comporte, en partie basse, une zone profilée en U 19, 20 s'étendant suivant l'axe A du module.Similarly, each lateral portion 13, 14 comprises, in the lower part, a profiled U-shaped zone 19, 20 extending along the axis A of the module.

Les ailes internes de chacune des deux zones profilées en U 19, 20 sont disposées de manière adjacente, les ailes externes comportant chacune une languette élastique d'encliquetage 21 faisant saillie vers l'intérieur du profilé en U correspondant.The inner wings of each of the two U-shaped profiled zones 19, 20 are disposed adjacently, the outer wings each having a resilient latching tongue 21 projecting inwardly from the corresponding U-profile.

Le corps 11 comporte en outre deux éléments de connexion 22, 23 faisant saillie vers le bas, chaque élément de connexion 22, 23 étant disposé sensiblement au niveau d'une extrémité du corps 11. De même que précédemment, les deux éléments de connexion 22, 23 sont disposés de part et d'autre du corps 11 par rapport au plan médian P de celui-ci, plus particulièrement au niveau de chaque aile interne des profilés en U 19, 20.The body 11 further comprises two connecting elements 22, 23 projecting downwards, each connecting element 22, 23 being disposed substantially at one end of the body 11. As before, the two connecting elements 22 , 23 are arranged on either side of the body 11 relative to the median plane P thereof, more particularly at each inner wing of the U-shaped profiles 19, 20.

Chaque élément de connexion 22, 23 forme une boucle élastique destinée à coopérer avec l'élément de connexion 4 du contacteur 1 correspondant.Each connecting element 22, 23 forms an elastic loop intended to cooperate with the connection element 4 of the corresponding contactor 1.

La figure 5 représente le module amovible 10 en perspective, de dessus, le capot 12 ayant été retiré pour des raisons de visibilité.The figure 5 represents the removable module 10 in perspective, from above, the hood 12 having been removed for visibility reasons.

Comme cela ressort de cette figure, le corps 11 comporte, au niveau de chaque partie latérale 13, 14, un logement débouchant 24 dans lequel est disposé un contact auxiliaire mobile 25, 26.As is apparent from this figure, the body 11 comprises, at each lateral portion 13, 14, a housing 24 opening in which is disposed a movable auxiliary contact 25, 26.

Un contact auxiliaire 25, 26 est représenté plus particulièrement en figure 6. Celui-ci comprend un poussoir mobile 28 avec des contacts mobiles reliés par un pont conducteur, les contacts mobiles étant destinés à coopérer avec des contacts fixes reliés à l'élément de connexion correspondant 22, 23 du module d'une part, et à la borne de raccordement correspondante du module d'autre part, par l'intermédiaire de portions conductrices 27, 29.An auxiliary contact 25, 26 is represented more particularly in figure 6 . This comprises a movable pusher 28 with movable contacts connected by a conductive bridge, the movable contacts being intended to cooperate with fixed contacts connected to the corresponding connecting element 22, 23 of the module on the one hand, and to the corresponding terminal terminal of the module on the other hand, via conductive portions 27, 29.

Chaque contact auxiliaire 25, 26 est du type normalement fermé. Lorsque le contact auxiliaire 25, 26 est actionné, c'est-à-dire lorsque le poussoir 28 est déplacé vers le bas, l'élément de connexion 22, 23 et la borne de raccordement 15, 16 sont électriquement déconnectés. A l'inverse, lorsque le contact auxiliaire 25, 26 n'est pas actionné, c'est-à-dire lorsque le poussoir 28 est entraîné vers le haut, la liaison électrique entre la borne de raccordement 15, 16 et l'élément de connexion 22, 23 est établie.Each auxiliary contact 25, 26 is of the normally closed type. When the auxiliary contact 25, 26 is actuated, that is to say when the pusher 28 is moved downwards, the connection element 22, 23 and the connection terminal 15, 16 are electrically disconnected. Conversely, when the auxiliary contact 25, 26 is not actuated, that is to say when the pusher 28 is driven upwards, the electrical connection between the connection terminal 15, 16 and the connection element 22, 23 is established.

Les déplacements du poussoir 28 sont obtenus par l'intermédiaire du coulisseau du contacteur correspondant, comme cela apparaîtra ci-après.The movements of the pusher 28 are obtained via the slider of the corresponding contactor, as will appear below.

Le module amovible 10 comporte ainsi une première borne de raccordement 15, un premier contact auxiliaire 25 et un premier élément de connexion 22, disposés au niveau de la première partie latérale 13 du module 10. Le premier contact auxiliaire 25 et le premier élément de connexion 22sont destinés à coopérer avec un premier contacteur 1'.The removable module 10 thus comprises a first connection terminal 15, a first auxiliary contact 25 and a first connection element 22, arranged at the level of the first lateral part 13 of the module 10. The first auxiliary contact 25 and the first connection element 22 are intended to cooperate with a first contactor 1 '.

De même, le module amovible 10 comporte une seconde borne de raccordement 16, un second contact auxiliaire 26 et un second élément de connexion 23, disposés au niveau de la seconde partie latérale 14 du module 10. Le second contact auxiliaire 26 et le second élément de connexion 23 sont destinés à coopérer avec un second contacteur 1", adjacent au premier contacteur 1'.Similarly, the removable module 10 comprises a second connection terminal 16, a second auxiliary contact 26 and a second connection element 23, arranged at the second lateral portion 14 of the module 10. The second auxiliary contact 26 and the second element connection 23 are intended to cooperate with a second contactor 1 "adjacent the first contactor 1 '.

Les figures 7 et 8 représentant le montage du module sur les contacteurs 1' et 1".The Figures 7 and 8 representing the assembly of the module on the contactors 1 'and 1 ".

Comme cela apparaît schématiquement en figure 9, la première borne de raccordement 15 est reliée électriquement à la patte mobile 29 du premier contact auxiliaire 25, la patte fixe 27 de ce dernier étant reliée électriquement au second élément de connexion 23 du module amovible 10.As it appears schematically in figure 9 , the first connection terminal 15 is electrically connected to the mobile tab 29 of the first auxiliary contact 25, the fixed tab 27 of the latter being electrically connected to the second connection element 23 of the removable module 10.

De même, la seconde borne de raccordement 16 est reliée électriquement à la patte mobile 29 du second contact auxiliaire 26, la patte fixe 27 de ce dernier étant reliée électriquement au premier élément de connexion 22 du module amovible 10.Similarly, the second connection terminal 16 is electrically connected to the mobile tab 29 of the second auxiliary contact 26, the fixed tab 27 of the latter being electrically connected to the first connection element 22 of the removable module 10.

Nous décrirons ci-après le montage du module amovible 10 sur les contacteurs 1', 1 "ainsi que le fonctionnement du montage.We will describe below the mounting of the removable module 10 on the contactors 1 ', 1 "and the operation of the assembly.

Le module amovible 10 vient se positionner au niveau de la face avant des contacteurs 1', 1", la première partie latérale 13 du module coopérant avec le premier contacteur 1', la seconde partie latérale 14 coopérant avec le second contacteur 1".The removable module 10 is positioned at the front face of the contactors 1 ', 1 ", the first side portion 13 of the module cooperating with the first contactor 1', the second side portion 14 cooperating with the second contactor 1".

C'est ainsi que les extrémités de chaque patte de fixation 17, 18 s'engagent dans l'évidement de fixation 9 du contacteur 1', 1" correspondant, les languettes élastiques 21 venant coopérer avec les rainures d'encliquetage 8 ménagées sur les contacteurs 1', 1 ".Thus, the ends of each fixing lug 17, 18 engage in the fixing recess 9 of the corresponding contactor 1 ', 1 ", the resilient tongues 21 cooperating with the snap-in grooves 8 formed on the contactors 1 ', 1 ".

En outre, chaque élément de connexion 22, 23 du module 10 coopère avec l'élément de connexion 4 d'un contacteur. C'est ainsi que les premier 22 et second 23 éléments de connexion du module permettent l'alimentation respective des bobines des premier 1' et second 1" contacteurs.In addition, each connection element 22, 23 of the module 10 cooperates with the connection element 4 of a contactor. Thus, the first 22 and second 23 connection elements of the module allow the respective supply of the coils of the first 1 'and second 1 "contactors.

De plus, le poussoir 28 de chaque contact auxiliaire 25, 26 du module est lié au coulisseau du contacteur correspondant de sorte que le l'actionnement du contact auxiliaire 25, 26, c'est-à-dire son ouverture lors de son déplacement vers le bas du poussoir 28, est réalisée par l'actionnement du coulisseau, lui-même actionné par la bobine de manière connue en soi.In addition, the pusher 28 of each auxiliary contact 25, 26 of the module is connected to the slider of the corresponding contactor so that the actuation of the auxiliary contact 25, 26, that is to say its opening during its movement towards the bottom of the pusher 28, is achieved by the actuation of the slider, itself actuated by the coil in a manner known per se.

Ainsi, les premier 25 et second 26 contacts auxiliaires sont actionnés lors de l'alimentation respective des bobines des premier 1' et second 1" contacteurs.Thus, the first 25 and second 26 auxiliary contacts are actuated during the respective supply of the coils of the first 1 'and second 1 "contactors.

Le circuit électrique extérieur est en outre raccordé au module 10 par l'intermédiaire des première 15 et seconde 16 bornes de raccordement.The external electrical circuit is further connected to the module 10 via the first 15 and second 16 connection terminals.

Ainsi, si le premier contacteur 1' est fermé, le coulisseau correspondant actionne le premier contact auxiliaire 25 du module 10. Dans ce cas, même si une tension est appliquée au niveau de la première borne de raccordement 15, la liaison électrique avec la bobine du second contacteur 1", par l'intermédiaire du second élément de connexion 23 et du premier contact auxiliaire 25, ne peut être réalisée.Thus, if the first contactor 1 'is closed, the corresponding slider actuates the first auxiliary contact 25 of the module 10. In this case, even if a voltage is applied at the first connection terminal 15, the electrical connection with the coil of the second contactor 1 ", via the second connecting element 23 and the first auxiliary contact 25 can not be realized.

En effet, comme vu précédemment, le contact auxiliaire du type normalement fermé empêche toute connexion électrique lorsqu'il est actionné.Indeed, as previously seen, the normally closed type auxiliary contact prevents any electrical connection when actuated.

C'est ainsi que lorsque le premier contacteur 1' est fermé, le second contacteur 1" ne peut l'être simultanément.Thus, when the first contactor 1 'is closed, the second contactor 1 "can not be simultaneously.

Au contraire, si le premier contacteur 1' est ouvert, l'application d'une tension au niveau de la première borne de raccordement 16 permet de fermer le second contacteur 1 ".On the contrary, if the first contactor 1 'is open, the application of a voltage at the first connection terminal 16 closes the second contactor 1 ".

De même, lorsque le second contacteur 1" est fermé, le second contact auxiliaire 25 du module 10 est actionné, de sorte que la bobine du premier contacteur 1' ne peut être alimentée.Similarly, when the second contactor 1 "is closed, the second auxiliary contact 25 of the module 10 is actuated, so that the coil of the first contactor 1 'can not be powered.

Ce montage, obtenu de manière simple et sans câblage manuel, permet d'interdire la fermeture simultanée de deux contacteurs 1', 1 ".This assembly, obtained in a simple manner and without manual wiring, allows to prohibit the simultaneous closure of two contactors 1 ', 1 ".
