Description

La présente invention concerne un appareil interrupteur électromécanique multipolaire comprenant des contacts principaux et des contacts auxiliaires logés dans un boîtier d'arc, un porte-contacts qui est mobile en translation à l'intérieur du boîtier d'arc et qui porte des logements auxiliaires pour les contacts auxiliaires situés devant des logements principaux pour les contacts principaux.The present invention relates to a multipolar electromechanical switch apparatus comprising main contacts and auxiliary contacts housed in an arc casing, a contact carrier which is movable in translation within the arc casing and which carries auxiliary housings for auxiliary contacts in front of main dwellings for main contacts.

Dans les appareils interrupteurs, le porte-contacts mobile, qui porte les contacts mobiles, fait un mouvement de translation d'avant en arrière à l'intérieur du boîtier d'arc de façon à pouvoir séparer ou plaquer ces contacts mobiles sur des contacts fixes situés sur le boîtier d'arc. Habituellement, lorsque les logements des contacts auxiliaires sont situés à côté des logements des contacts principaux selon un même plan vertical, l'isolation entre logements principaux et auxiliaires peut être assurée par une paroi longitudinale, parallèle à la direction du mouvement du porte-contacts, par exemple du même type que les parois interpolaires des logements principaux. Cette paroi peut donc être facilement réalisée dans le porte-contacts ou dans le boîtier d'arc, sans gêner le mouvement du porte-contacts. Cependant, lorsque le plan vertical des logements des contacts auxiliaires est différent, par exemple en avant, du plan vertical des logements des contacts principaux, l'isolation entre logements principaux et auxiliaires doit être assurée par une paroi transversale (ou perpendiculaire) au mouvement du porte-contacts mobile, et qui sera susceptible de gêner ce mouvement de translation si l'on veut garder une taille réduite pour l'appareil interrupteur. Le document "FR-A-2 519 186" décrit un appareil interrupteur selon le préambule de la revendication indépendante 1.In the switch devices, the movable contact carrier, which carries the movable contacts, translates back and forth within the arc housing so as to separate or press these movable contacts on fixed contacts. located on the arc case. Usually, when the housings of the auxiliary contacts are located next to the housings of the main contacts in a same vertical plane, the insulation between main and auxiliary housing can be provided by a longitudinal wall, parallel to the direction of movement of the contact carrier, for example of the same type as the interpolar walls of the main dwellings. This wall can be easily made in the contact holder or in the arc housing, without impeding the movement of the contact carrier. However, when the vertical plane of the housings of the auxiliary contacts is different, for example forward, of the vertical plane of the housing of the main contacts, the insulation between main and auxiliary housing must be ensured by a wall transverse (or perpendicular) to the movement of the mobile contact holder, and which will be likely to hinder this translational movement if one wants to keep a small size for the switch device. The document "FR-A-2 519 186" describes a switch device according to the preamble of independent claim 1.

L'invention a donc pour but de créer de façon simple et compacte une isolation entre les logements des contacts principaux et les logements des contacts auxiliaires, quand ces logements sont dans des plans verticaux différents, sans adjonction de pièce supplémentaire et tout en gardant une intégration aisée du porte-contacts dans le boîtier d'arc lors de la fabrication de l'appareil interrupteur.The invention therefore aims to create a simple and compact insulation between the housing of the main contacts and the housing of the auxiliary contacts, when these housings are in different vertical planes, without adding additional room and while maintaining integration easy of the contact holder in the arc housing during the manufacture of the switch device.

Selon l'invention, le porte-contacts comprend des logements auxiliaires pour des contacts auxiliaires, ces logements auxiliaires étant alignés transversalement à la direction de déplacement du porte-contacts et situés devant les logements principaux des contacts principaux. Entre les logements principaux et les logements auxiliaires, le porte-contacts comprend une paroi d'isolement verticale composée de plusieurs joues d'isolement polaires séparées par des fentes interpolaires. Pour pouvoir insérer facilement le porte-contacts dans le boîtier d'arc, celui-ci se compose de deux moitiés de boîtier assemblées par emboîtement et/ou encliquetage mutuel selon un plan horizontal, de manière que l'une au moins des deux moitiés présente des éléments de guidage du porte-contacts et des éléments de butée pour celui-ci. De plus, chaque moitié du boîtier d'arc comprend une cloison d'isolement entre contacts principaux et contacts auxiliaires.According to the invention, the contact carrier comprises auxiliary housings for auxiliary contacts, these auxiliary housings being aligned transversely to the direction of movement of the contact carrier and located in front of the main housing. main contacts. Between the main housing and the auxiliary housing, the contact carrier comprises a vertical isolation wall composed of several polar isolation flanges separated by interpolar slots. In order to be able to easily insert the contact holder into the bow case, it consists of two housing halves assembled by interlocking and / or interlocking in a horizontal plane, so that at least one of the two halves presents guiding elements of the contact carrier and stop elements therefor. In addition, each half of the arc housing comprises an isolation wall between main contacts and auxiliary contacts.

La description est faite ci-après d'un mode de réalisation préférentiel et non limitatif de l'invention, en regard des dessins annexés suivants :

  • la figure 1 montre une vue en perspective du porte-contacts d'un appareil interrupteur, entouré de deux moitiés de boîtier d'arc, sans représentation des contacts.
The description is made below of a preferred and nonlimiting embodiment of the invention, with reference to the following appended drawings:
  • Figure 1 shows a perspective view of the contact carrier of a switch device, surrounded by two halves of arc housing, without representation of the contacts.

L'appareil interrupteur décrit dans le mode de réalisation schématisé figure 1 comporte, à l'intérieur d'un corps isolant, trois pôles principaux à double coupure et deux pôles auxiliaires. Les pôles principaux sont dotés chacun de deux contacts fixes situés dans un boîtier d'arc 20,40. Ces contacts fixes, non représentés sur la figure 1, se logent dans des chambres principales 21,41 du boîtier d'arc. Les pôles principaux sont également dotés chacun de deux contacts mobiles, non représentés sur la figure 1, fixés dans des logements principaux 31 d'un porte-contacts mobile 30. De la même façon, les différents pôles auxiliaires sont dotés de contacts fixes situés dans des chambres auxiliaires 22,42 du boîtier d'arc 20,40, et de contacts mobiles fixés dans des logements auxiliaires 32 du porte-contacts 30. A l'intérieur du boîtier d'arc 20,40, le porte-contacts 30 est mobile en translation suivant un axe X horizontal, assurant la séparation ou le plaquage des contacts mobiles sur les contacts fixes.The switch device described in the embodiment shown schematically in Figure 1 comprises, inside an insulating body, three main poles with double break and two auxiliary poles. The main poles are each provided with two fixed contacts located in an arc housing 20,40. These fixed contacts, not shown in Figure 1, are housed in the main chambers 21,41 of the arc housing. The main poles are also each provided with two movable contacts, not shown in FIG. 1, fixed in main housings 31 of a movable contact holder 30. Similarly, the various auxiliary poles are provided with fixed contacts located in auxiliary chambers 22, 42 of the arc casing 20, 40, and movable contacts fixed in auxiliary housings 32 of the contact carrier 30. Inside the arc casing 20, the contact carrier 30 is movable in translation along a horizontal axis X, ensuring the separation or the plating of the movable contacts on the fixed contacts.

Les logements principaux 31 sont alignés transversalement à la direction de déplacement X du porte-contacts 30 et sont situés dans un plan vertical distinct de celui des logements auxiliaires 32, eux aussi étant alignés transversalement à la direction X. Dans toute la description, cet axe horizontal X correspond à une direction appelée avant/arrière de l'appareil interrupteur, le côté avant de l'appareil étant le côté des logements auxiliaires 32 et le côté arrière de l'appareil étant le côté des logements principaux 31. Le porte-contacts 30 est solidaire de la partie mobile d'un électroaimant situé à l'arrière de l'appareil et dont le déplacement est provoqué par la circulation d'un courant dans une bobine de l'électroaimant.The main housings 31 are aligned transversely to the direction of travel X of the contact carrier 30 and are located in a vertical plane distinct from that of the auxiliary housing 32, also being aligned transversely to the direction X. Throughout the description, this axis horizontal X corresponds to a direction called front / rear of the switch device, the front side of the device being the side of the auxiliary housing 32 and the rear side of the device being the side of the housing 31. The contact carrier 30 is secured to the movable portion of an electromagnet at the rear of the apparatus and whose displacement is caused by the flow of a current in a coil of the electromagnet.

Entre les logements principaux 31 et les logements auxiliaires 32, le boîtier d'arc 30 comprend une paroi d'isolement verticale 35 destinée à contribuer à l'isolation entre les logements principaux 31 et les logements auxiliaires 32. Cette paroi est transversale par rapport à l'axe X et est composée de plusieurs joues d'isolement polaires 36 séparées par des fentes interpolaires 37. En assurant une isolation efficace dans un faible encombrement, elle permet de maintenir une taille compacte du porte-contacts.Between the main housing 31 and the auxiliary housing 32, the arc housing 30 comprises a vertical isolation wall 35 intended to contribute to the insulation between the main housing 31 and the auxiliary housing 32. This wall is transverse to the the X axis and is composed of several polar isolation flanges 36 separated by interpolar slots 37. By providing effective isolation in a small footprint, it maintains a compact size of the contact carrier.

Etant donné l'encombrement pris par la paroi verticale d'isolement 35, il deviendrait difficile d'insérer directement le porte-contacts 30 dans le boîtier d'arc durant la fabrication de l'appareil interrupteur. C'est pourquoi le boîtier d'arc est constitué de deux moitiés de boîtier : une moitié supérieure 20 et une moitié inférieure 40, assemblées par emboîtement et/ou encliquetage mutuel selon un plan horizontal qui peut être le plan médian horizontal P du porte-contacts 30 ou un plan parallèle à P. Cet assemblage est, par exemple, matérialisé par des moyens d'encliquetage 49 sur la moitié inférieure 40 coopérant avec des moyens d'encliquetage complémentaires 29 sur la moitié supérieure 20. De plus, des moyens d'emboîtement 48 sur la moitié inférieure 40 coopèrent avec des moyens d'emboîtement complémentaires 28 sur la moitié supérieure 20 pour assurer un meilleur guidage et une meilleure fixation des deux moitiés 20,40 du boîtier d'arc l'une dans l'autre.Given the bulk taken by the vertical isolation wall 35, it would become difficult to directly insert the contact holder 30 in the arc housing during the manufacture of the switch device. This is why the arc housing consists of two housing halves: an upper half 20 and a lower half 40, assembled by interlocking and / or mutual snapping in a horizontal plane which may be the horizontal median plane P of the carrier. contacts 30 or a plane parallel to P. This assembly is, for example, materialized by latching means 49 on the lower half 40 cooperating with complementary latching means 29 on the upper half 20. In addition, means interlocking 48 on the lower half 40 cooperate with complementary interlocking means 28 on the upper half 20 to provide better guidance and better attachment of the two halves 20,40 of the arc housing to one another.

Ainsi, lors de la fabrication de l'appareil interrupteur, il devient aisé d'assembler le boîtier d'arc en positionnant d'abord le porte-contacts 30 sur la moitié inférieure 40, par exemple, puis en emboîtant dessus la moitié supérieure 20. Le porte-contacts 30 présente une symétrie suivant son plan médian horizontal P et les deux moitiés du boîtier d'arc sont disposées de part et d'autre, de manière sensiblement symétrique par rapport à ce plan P.Thus, during the manufacture of the switch device, it becomes easy to assemble the arc casing by first positioning the contact holder 30 on the lower half 40, for example, and then fitting on the upper half 20 The contact carrier 30 has a symmetry along its horizontal median plane P and the two halves of the arc housing are arranged on both sides, substantially symmetrically with respect to this plane P.

Une fois assemblées, les deux moitiés 20,40 du boîtier d'arc permettent au porte-contacts 30 de coulisser uniquement suivant l'axe horizontal X grâce à des éléments de guidage présents sur l'une au moins des deux moitiés 20,40. Ces éléments de guidage comprennent, par exemple sur la moitié inférieure 40, deux séparations interpolaires principales 43 entre les trois chambres principales 41 et une séparation interpolaire auxiliaire 44 entre les deux chambres auxiliaires 42. Sur la moitié supérieure 20, ces éléments de guidage peuvent également comprendre deux séparations interpolaires principales 23 entre les trois chambres principales 21. Ces séparations coopèrent avec des éléments de forme complémentaires situés entre les logements principaux 31 et entre les logements auxiliaires 32 du porte-contacts 30. De plus, les séparations interpolaires principales 23,43 viennent s'insérer dans les fentes interpolaires 37 de la paroi d'isolement 35 de façon à ne pas gêner le mouvement de coulissement du porte-contacts.Once assembled, the two halves 20,40 of the arc case allow the contact holder 30 to slide only along the horizontal axis X by means of guide elements present on at least one of the two halves 20,40. These guide elements comprise, for example on the lower half 40, two main interpolar separations 43 between the three main chambers 41 and an auxiliary interpolar separation 44 between the two auxiliary chambers 42. On the upper half 20, these guide elements can also understand two primary interpolations 23 between the three main chambers 21. These separations cooperate with complementary shaped elements located between the main housing 31 and between the auxiliary housing 32 of the contact carrier 30. In addition, the main interpolar separations 23,43 are s insert in the interpolar slots 37 of the isolation wall 35 so as not to interfere with the sliding movement of the contact carrier.

Chaque moitié du boîtier d'arc 20,40 comprend également une cloison d'isolement 26,46 entre les chambres principales 21,41 des contacts principaux et les chambres auxiliaires 22,42 des contacts auxiliaires. Outre leur contribution à l'isolation entre les chambres, les cloisons d'isolement 26,46 définissent une butée avant pour les joues d'isolement 36 de la paroi d'isolement 35 limitant ainsi la course du porte-contacts 30.Each half of the arc casing 20, 40 also includes an isolation wall 26, 46 between the main chambers 21, 41 of the main contacts and the auxiliary chambers 22, 42 of the auxiliary contacts. In addition to their contribution to the insulation between the chambers, the isolation partitions 26, 46 define a front stop for the isolation flanges 36 of the isolation wall 35 thus limiting the travel of the contact carrier 30.
