En fonction du type de l'installation électrique d'un client, les disjoncteurs de protection peuvent être unipolaires ou multipolaires avec deux, trois ou quatre pôles. Selon le calibre du disjoncteur, et le type de protection recherchée, il faut en plus adapter certains éléments ou pièces, notamment le mécanisme, le barreau de commutation, les pièces de contacts, les chambres de coupure, et les déclencheurs. Une gamme de disjoncteurs nécessite à cet effet une multitude de variantes. La fabrication d'une telle gamme pose des problèmes d'assemblage, car les pièces ou éléments à adapter n'ont toujours les mêmes formes ou structures, et ne sont pas facilement interchangeables.Depending on the type of customer's electrical installation, the protective circuit breakers can be single-pole or multi-pole with two, three or four poles. Depending on the size of the circuit breaker, and the type of protection sought, it is also necessary to adapt certain elements or parts, in particular the mechanism, the switching bar, the contact parts, the breaking chambers, and the trip devices. A range of circuit breakers requires a multitude of variants for this purpose. The manufacture of such a range poses assembly problems, because the parts or elements to be adapted always have the same shapes or structures, and are not easily interchangeable.

L'objet de l'invention consiste à réaliser un disjoncteur multipolaire ayant une architecture modulaire autorisant la construction de plusieurs types avec des modules à encombrement standard.The object of the invention is to provide a multipole circuit breaker having a modular architecture allowing the construction of several types with modules with standard dimensions.

Le disjoncteur selon l'invention est caractérisé en ce que :

  • chaque module de coupure est formé par une ampoule monobloc parallélépipèdique en matière plastique, logée dans le compartiment correspondant du socle, ladite ampoule renfermant au moins un contact fixe, une chambre d'extinction d'arc, et une paire de plages de raccordement à une borne et au module de déclenchement du même pôle,
  • un module d'actionnement mécanique, constitué par l'ensemble barreau de commutation et mécanisme, est rendu solidaire du couvercle,
  • la barre de déclenchement rotative est supportée par des moyens de clipsage, ménagés à la face inférieure du couvercle,
  • et une pluralité d'évidements et de découpes agencés dans les entretoises du socle pour servir de premières surfaces d'appui respectivement pour le barreau de commutation et la barre de déclenchement lors de l'accolement du premier sous-ensemble A composé du socle avec l'ensemble des modules de coupure et des modules de déclenchement, et du deuxième sous-ensemble B constitué par le couvercle auquel sont rapportés le module d'actionnement mécanique, la barre de déclenchement et le verrou.
The circuit breaker according to the invention is characterized in that:
  • each breaking module is formed by a monobloc parallelepiped plastic bulb, housed in the corresponding compartment of the base, said bulb containing at least one fixed contact, an arc extinguishing chamber, and a pair of connection pads to a terminal and to the trigger module of the same pole,
  • a mechanical actuation module, constituted by the switch bar and mechanism assembly, is made integral with the cover,
  • the rotary trip bar is supported by clipping means, provided on the underside of the cover,
  • and a plurality of recesses and cutouts arranged in the spacers of the base to serve as first bearing surfaces respectively for the switching rod and the trigger bar when the first subassembly A composed of the base is joined with the 'set of cut-off modules and trigger modules, and the second sub-assembly B consisting of the cover to which are reported the mechanical actuation module, the trigger bar and the latch.

A partir des différents types de modules de coupure, de déclenchement et d'actionnement mécanique, il est possible de fabriquer toute une gamme de disjoncteurs à boîtier isolant moulé en fonction des performances et des calibres souhaités. La structure du boîtier , pour un nombre de pôles prédéterminé, reste identique indépendamment des modules choisis pour l'assemblage. Le positionnement du barreau de commutation s'effectue simultanément avec celui de la barre de déclenchement lors de l'accolement des deux sous-ensembles prémontés.From the different types of cut-off, tripping and mechanical actuation modules, it is possible to manufacture a whole range of circuit breakers with insulated molded housing depending on the desired performance and ratings. The structure of the housing, for a predetermined number of poles, remains identical regardless of the modules chosen for assembly. The positioning of the switching bar takes place simultaneously with that of the trip bar when the two pre-assembled sub-assemblies are joined.

Du côté du socle, le barreau est positionné dans deux demi-paliers inférieurs formés par la juxtaposition des évidements des entretoises, et des encoches prévues dans les grandes faces latérales des ampoules. Du côté du couvercle, les demi-paliers supérieurs du barreau sont formés par des surfaces d'appui incurvées solidaires des platines du mécanisme.On the side of the base, the bar is positioned in two lower half-bearings formed by the juxtaposition of the recesses of the spacers, and of the notches provided in the large lateral faces of the bulbs. On the cover side, the upper half-bearings of the bar are formed by curved bearing surfaces integral with the plates of the mechanism.

Sur les figures 1 et 2, un pôle d'un disjoncteur multipolaire 10 à boîtier 12 isolant moulé, comporte un module de coupure 14 unipolaire, formé par une ampoule 16 monobloc en matière plastique moulée, et ayant une forme de parallélépipède rectangle. L'ampoule 16 comprend un fond 18, une face avant 20 ayant un orifice 22 de passage du contact mobile 24, deux grandes faces latérales parallèles 26, 28 et deux petites faces 30, 32 parallèles de raccordement.In FIGS. 1 and 2, a pole of a multipolar circuit breaker 10 with molded insulating housing 12, comprises a single-pole breaking module 14, formed by a one-piece bulb 16 made of molded plastic, and having the shape of a rectangular parallelepiped. The bulb 16 comprises a bottom 18, a front face 20 having an orifice 22 for the passage of the movable contact 24, two large parallel lateral faces 26, 28 and two small parallel faces 30, 32 for connection.

A l'intérieur de l'ampoule 16 se trouvent deux contacts fixes 34, 36 reliés respectivement par des conducteurs 35, 37 de liaison à une première plage 38 d'une borne de raccordement 40, et à une deuxième plage 42 destinée à être connectée par une vis 43 à une troisième plage de contact 44 d'un module de déclenchement 46.Inside the bulb 16 are two fixed contacts 34, 36 connected respectively by conductors 35, 37 for connection to a first pad 38 of a connection terminal 40, and to a second pad 42 intended to be connected by a screw 43 to a third contact pad 44 of a trigger module 46.

Le dispositif de déclenchement comporte un module déclencheur 46 dont celui de la figure 1, est formé par un déclencheur magnétothermique, équipé à l'opposé de la plage 44, d'une quatrième plage de contact 48 faisant partie de l'autre borne 50 de raccordement du pôle. Le module déclencheur 46 est inséré en série dans le pôle avec les contacts 34, 36, 24 du module de coupure 14.
Dans l'état fermé du disjoncteur, le courant rentre par la borne 40 d'entrée, et circule successivement dans le conducteur 35, le contact fixe 34, le contact mobile 24, l'autre contact fixe 36, le conducteur 37, les plages 42, 44, le déclencheur 46, et la borne 50 de sortie.The triggering device comprises a trigger module 46, the one of which in FIG. 1, being formed by a magnetothermal trigger, equipped opposite the pad 44, with a fourth contact pad 48 forming part of the other terminal 50 of pole connection. The trip module 46 is inserted in series in the pole with the contacts 34, 36, 24 of the cut-off module 14.
In the closed state of the circuit breaker, the current enters through the input terminal 40, and flows successively through the conductor 35, the fixed contact 34, the movable contact 24, the other fixed contact 36, the conductor 37, the ranges 42, 44, the trigger 46, and the output terminal 50.

Le dispositif de déclenchement comprend de plus une barre de déclenchement 52 montée à rotation limitée entre une position armée et une position déclenchée en fonction de la position de l'organe d'actionnement du déclencheur 46, par exemple la bilame 54 ou la palette 56. La barre 52 rotative est déplacée vers la position déclenchée dès que le courant circulant dans le pôle dépasse un seuil prédéterminé. La barre de déclenchement 52 coopère d'autre part avec un verrou 58 d'accrochage d'un mécanisme 60 de commande à genouillère 62 et à manette 64.The triggering device further comprises a trigger bar 52 mounted with limited rotation between an armed position and a triggered position as a function of the position of the actuator of the trigger 46, for example the bimetallic strip 54 or the pallet 56. The rotary bar 52 is moved to the triggered position as soon as the current flowing in the pole exceeds a predetermined threshold. The trigger bar 52 also cooperates with a latch 58 for hooking a control mechanism 60 with toggle joint 62 and to lever 64.

Le mécanisme 60 est commun à l'ensemble des pôles, et est logé dans le boîtier 12 entre deux platines support 66, 68 métalliques, seule la manette 64 étant accessible de l'extérieur en traversant une lumière 65 de passage du boîtier 12, pour la commande du disjoncteur 10.The mechanism 60 is common to all of the poles, and is housed in the housing 12 between two metal support plates 66, 68, only the handle 64 being accessible from the outside by passing through a lumen 65 passing through the housing 12, to circuit breaker control 10.

Le mécanisme 60 comporte un crochet de déclenchement 70 monté à pivotement sur les platines 66, 68 parallèles, l'extrémité libre du crochet 70 étant en prise avec le verrou 58 en position armée. Un ressort 72 d'embiellage est ancré entre l'axe 74 d'articulation de la genouillère 62, et un axe 76 solidaire de l'embase 78 de la manette 64.The mechanism 60 comprises a trigger hook 70 pivotally mounted on the plates 66, 68 parallel, the free end of the hook 70 being engaged with the latch 58 in the armed position. A connecting rod spring 72 is anchored between the axis 74 of articulation of the toggle joint 62, and an axis 76 integral with the base 78 of the lever 64.

La biellette inférieure 80 de la genouillère 62 est accouplée à une protubérance 81 d'un barreau 82 de commutation servant de support aux contacts mobiles 24 de tous les pôles. Le barreau 82 de commutation est réalisé en matériau isolant et s'étend parallèlement à la barre de déclenchement 52 dans la direction transversale des pôles. La biellette supérieure de la genouillère 62 est articulée sur le crochet de déclenchement 70.The lower link 80 of the toggle joint 62 is coupled to a protuberance 81 of a switching bar 82 serving to support the movable contacts 24 of all the poles. The switching bar 82 is made of insulating material and extends parallel to the trigger bar 52 in the transverse direction of the poles. The upper link of the toggle joint 62 is articulated on the trigger hook 70.

Une action de déverrouillage de la barre de déclenchement 52 sur le verrou 58 libère le crochet 70, lequel se désarme sous l'action de détente du ressort 72 d'embiellage, entraînant le déplacement par pivotement de la genouillère 62, et la rotation du barreau 82 vers la position d'ouverture des contacts 34, 36, 24 de tous les pôles. L'ordre de déverouillage du verrou 58 peut provenir du module déclencheur 46 magnétothermique, ou d'un déclencheur auxiliaire, notamment à manque de tension MN, à émission de courant MX, différentiel, etc...An unlocking action of the trigger bar 52 on the latch 58 releases the hook 70, which disarms under the relaxing action of the connecting rod spring 72, causing the pivoting movement of the toggle joint 62, and the rotation of the bar 82 to the open position of contacts 34, 36, 24 of all the poles. The unlocking order of the lock 58 can come from the magnetothermal trip module 46, or from an auxiliary trip device, in particular with a lack of voltage MN, with emission of current MX, differential, etc.

Le module de coupure 14 renferme en plus deux chambres d'extinction d'arc, dont une 84 est représentée sur la figure 1. La sortie de la chambre 84 se trouve en communication avec une ouverture 86 d'échappement des gaz de coupure vers l'extérieur de l'ampoule 16.The cut-off module 14 additionally contains two arc extinguishing chambers, one of which 84 is shown in FIG. 1.
