- a casing made of molded insulating material formed by the assembly of an intermediate casing and two half-shells, fixed in parallel with one another by fixing means,
- phase and neutral connection terminals arranged on the opposite narrow faces of the housing,
- a partition of said housing being extended longitudinally to the receiving cells of said terminals, and dividing the lower part of the housing into a first phase contact housing compartment and a second neutral contact housing compartment, the volume of the first compartment being higher than in the second compartment,
- a bimetallic thermal trip device having the foot arranged in the first compartment,

Un tel disjoncteur est décrit dans le document FR-A-2.485.254, qui permet de placer dans un même boîtier isolant un circuit de phase et un circuit de neutre, isolés l'un de l'autre. Au niveau des contacts de phase et de neutre, la cloison de séparation est décalée par rapport au plan médian, et la bilame s'étend jusque dans la partie supérieure du boîtier. L'incorporation d'une chambre d'extinction d'arc dans le deuxième compartiment de neutre est impossible si les dimensions standards du boîtier modulaire doivent être conservées.Such a circuit breaker is described in document FR-A-2,485,254, which makes it possible to place in a same insulating case a phase circuit and a neutral circuit, isolated from each other. At the phase and neutral contacts, the partition is offset from the median plane, and the bimetallic strip extends into the upper part of the housing. The incorporation of an arc extinguishing chamber in the second neutral compartment is impossible if the standard dimensions of the modular housing must be maintained.
Le document DE-A-2.234.423 montre l'augmentation de l'encombrement du boîtier avec deux chambres d'extinction d'arc, et un déclencheur électromagnétique qui occupe une fraction de la largeur du boîtier.Document DE-A-2.234.423 shows the increase in the size of the box with two arc extinguishing chambers, and an electromagnetic trip device which occupies a fraction of the width of the box.
Les documents EP-A-403.358 et EP-A-252.786 décrivent chacun un disjoncteur unipolaire et neutre ayant une cloison intermédiaire de séparation entre les deux circuits de phase et de neutre. Une première partie de la cloison s'étend dans le plan médian au niveau des chambres de coupure, et une deuxième partie est déportée latéralement dans laquelle est agencée le déclencheur électromagnétique. Le percuteur du déclencheur électromagnétique n'est pas situé dans le plan médian du boîtier, et il en résulte que le déclencheur électromagnétique n'occupe pas toute la largeur du boîtier. Les performances de coupure d'un tel disjoncteur restent limitées.The documents EP-A-403.358 and EP-A-252.786 each describe a single-pole and neutral circuit breaker having an intermediate partition for separation between the two phase and neutral circuits. A first part of the partition extends in the median plane at the level of the breaking chambers, and a second part is offset laterally in which the electromagnetic trip device is arranged. The striker of the electromagnetic trip device is not located in the median plane of the box, and as a result the electromagnetic trip device does not occupy the entire width of the box. The breaking performance of such a circuit breaker remains limited.
L'objet de l'invention consiste à améliorer les performances électriques d'un disjoncteur phase et neutre à boîter standard, et à deux chambres d'extinction d'arc.The object of the invention is to improve the electrical performance of a phase and neutral circuit breaker with standard box, and two arc extinguishing chambers.
Le disjoncteur selon l'invention est caractérisé en ce que la cloison de séparation se trouve en majorité dans le plan médian du boîtier, notamment entre les bornes et les chambres d'extinction d'arc respectives des premier et deuxième compartiments de phase et de neutre, que la bilame s'étend en totalité dans le premier compartiment à l'intérieur d'un espace additionnel confiné par le décalage latéral de la cloison faisant saillie dans le deuxième compartiment, la longueur de l'espace dans le sens longitudinal étant légèrement supérieure à la course maximum de déflexion de la bilame, et que le percuteur du déclencheur électromagnétique est agencé dans ledit plan médian, et coopère lors d'un déclenchement sur court-circuit successivement avec le levier de déclenchement déplaçable vers la position déclencheé, et avec les deux porte-contacts des contacts mobiles de phase et de neutre entraînés simultanément vers la position d'ouverture.The circuit breaker according to the invention is characterized in that the separation partition is mostly located in the median plane of the housing, in particular between the terminals and the respective arc extinguishing chambers of the first and second phase and neutral compartments , that the bimetallic strip extends entirely in the first compartment inside an additional space confined by the lateral offset of the partition projecting in the second compartment, the length of the space in the longitudinal direction being slightly greater at the maximum deflection travel of the bimetallic strip, and that the striker of the electromagnetic trip device is arranged in said median plane, and cooperates during a tripping on short circuit successively with the tripping lever displaceable towards the tripped position, and with the two contact carriers of the phase and neutral movable contacts driven simultaneously towards the open position.
Un tel agencement permet d'augmenter le calibre d'un disjoncteur unipolaire et neutre, sans modifier le boîtier.Such an arrangement makes it possible to increase the rating of a single-pole and neutral circuit breaker, without modifying the housing.
Le décalage latéral de la cloison par rapport au plan médian correspond sensiblement à la moitié de la largeur du deuxième compartiment de neutre.The lateral offset of the partition with respect to the median plane corresponds substantially to half the width of the second neutral compartment.
Le pied de la bilame est situé au voisinage du fond du boîtier, tandis que l'extrémité libre de la bilame se trouve au niveau de l'interface de séparation avec la partie supérieure du boîtier.The foot of the bimetallic strip is located near the bottom of the housing, while the free end of the bimetallic strip is located at the separation interface with the upper part of the housing.
D'autres avantages et caractéristiques ressortiront plus clairement de la description qui va suivre d'un mode de réalisation de l'invention, donné à titre d'exemple non limitatif, et représenté aux dessins annexés, dans lesquels:Other advantages and characteristics will emerge more clearly from the description which follows of an embodiment of the invention, given by way of nonlimiting example, and represented in the appended drawings, in which:
La figure 1 est une vue en élévation d'un disjoncteur phase et neutre selon l'invention,la demi-coquille du côté circuit phase étant enlevée.Figure 1 is an elevational view of a phase and neutral circuit breaker according to the invention, the half-shell on the phase circuit side being removed.
La figure 2 est une vue de profil de la figure 1.Figure 2 is a side view of Figure 1.
Les figures 3 et 4 représentent des coupes selon les lignes 3-3 et 4-4 de la figure 1.Figures 3 and 4 show sections along lines 3-3 and 4-4 of Figure 1.
La figure 5 est une vue identique de la figure 3 d'une variante de réalisation.Figure 5 is an identical view to Figure 3 of an alternative embodiment.
Sur les figures, un disjoncteur 10 miniature phase et neutre est logé dans un boîtier 12 en matériau isolant moulé, formé par l'assemblage d'un carter 14 intermédiaire et de deux demi-coquilles 16,18,fixés parallèlement entre eux par des moyens de fixation, notamment des rivets 20.In the figures, a miniature phase and
Le carter 14 isolant intermédiaire est équipé d'une cloison 22 continue de séparation s'étendant longitudinalement dans le plan médian perpendiculaire aux faces étroites 24,26 de raccordement du boîtier 12. La cloison 22 subdivise la partie inférieure du boîtier 12 en deux volumes adjacents, à savoir un premier compartiment 28 de phase, et un deuxième compartiment 30 de neutre.The intermediate
Le circuit de neutre logé dans le deuxième compartiment 30, comporte une chambre d'extinction d'arc associée à une paire de contacts de neutre (non représentée), et une paire de bornes de neutre 32,34, disposée sur les faces opposées étroites 24,26 du boîtier 12.The neutral circuit housed in the
Le premier compartiment 28 de phase renferme une chambre d'extinction d'arc associée à une paire de contacts de phase(non représentée), une paire de bornes de phase 36,38, et un déclencheur thermique à bilame 40. On remarque que tous les éléments actifs du circuit de phase sont contenus dans le premier compartiment 28, à l'exception du déclencheur électromagnétique 42 à bobine 44 d'excitation qui se trouve avec le mécanisme de commande 43 dans la partie supérieure 41 du boîtier 12, laquelle est située dans le sens de la hauteur entre la cloison 22 de séparation, et la face avant 45 du boîtier 12.The
Le mécanisme de commande 43 est décrit à titre d'exemple dans le brevet français n°2.616.583, et est piloté soit manuellement par une manette 46 pivotante à deux positions stables correspondant à l'ouverture et à la fermeture des contacts, soit automatiquement en cas de surcharge ou de court-circuit par l'action des deux déclencheurs 42,40 sur le levier de déclenchement 48, représentée partiellement sur la figure 4.The
La cloison 22 du carter 14 intermédiaire se prolonge longitudinalement jusqu'aux faces opposées étroites 24,26 du boîtier 12 et coopèrent avec les deux demi-coquilles 16,18 pour former les alvéoles 50 de réception des bornes 32,34,36,38 de raccordement. La cloison 22 médiane s'étend entre chaque borne de neutre 32,34 et la borne de phase 36,38 adjacente.The
Le mécanisme 43 est accouplé à deux porte contacts phase et neutre 52,54 juxtaposés servant de support aux contacts mobiles de phase et de neutre. Le déclencheur électromagnétique 42 comporte un percuteur 56 solidarisé à un noyau mobile 58 en matériau ferromagnétique susceptible d'être déplacé par attraction magnétique contre un noyau fixe 60 lorsque le courant de phase circulant dans la bobine 44 d'excitation dépasse un seuil prédéterminé.The
Le fonctionnement d'un disjoncteur 10 phase et neutre est bien connu des spécialistes. Le mécanisme 43 à manette 46 est commun aux deux porte-contacts 52,54 de phase et de neutre, et occupe avec le déclencheur électromagnétique 42, toute la largeur de la partie supérieure 41 du boîtier 12.The operation of a 10 phase and neutral circuit breaker is well known to specialists. The
L'apparition d'un courant de surcharge dans le circuit de phase provoque la déflexion vers la droite de la bilame (figure 1 et 3), entraînant le déclenchement automatique du mécanisme 43, et l'ouverture des contacts de phase et de neutre.The appearance of an overload current in the phase circuit causes the bimetallic strip to deflect to the right (FIGS. 1 and 3), causing the
Le déclencheur électromagnétique 42 intervient lors d'une détection d'un courant de court-circuit, provoquant l'attraction du noyau mobile 58 contre le noyau fixe 60. Le déplacement en translation du percuteur 56 s'effectue vers la droite (figure 4) dans le plan médian du boîtier 12, de manière à faire pivoter dans un premier stade le levier de déclenchement 48 vers la position déclenchée, puis à entraîner dans un deuxième stade les deux porte contacts 52,54 vers la position d'ouverture. L'entraînement des deux porte-contacts 52,54 peut être simultané, et s'effectue directement sans pièce de transmission intermédiaire.The
Le pied 61 de la bilame 40 est situé au voisinage du fond 62 du boîtier 12, et est fixé d'une part à l'extrémité d'une corne de guidage d'arc 64 associé à la chambre d'extinction d'arc du circuit de phase, et d'autre part à une plage de contact 66 de la borne de phase 38.Le réglage du seuil de déclenchement thermique de la bilame 40 s'effectue par déformation du pied 61 au moyen d'une vis 68 logée dans un orifice 70 qui débouche dans la face étroite 26 du boîtier 12, sous la borne de phase 38. L'orifice 70 est ménagé dans la partie inférieure du carter intermédiaire 14.The
L'extrémité libre de la bilame 40 se trouve au niveau de l'interface de séparation avec la partie supérieure du boîtier 12.The free end of the
Au niveau des bornes 32,36; 34,38, et des deux chambres d'extinction d'arc des circuits de phase et de neutre,la cloison 22 de séparation se trouve dans le plan médian du boîtier 12. Dans la zone de déflexion de la bilame 40, la cloison 22 est décalée par rapport au plan médian, et fait saillie dans le deuxième compartiment 30 de neutre.Il en résulte que le volume du premier compartiment 28 de phase est supérieur à celui du deuxième compartiment 30 de neutre. La différence de volume résulte de la présence d'un espace additionnel 72 confiné au niveau de la bilame 40 par le décalage latéral de la cloison 22.At terminals 32.36; 34, 38, and of the two arc extinction chambers of the phase and neutral circuits, the
La longueur de l'espace 72 dans le sens longitudinal est légèrement supérieure à la course maximum de déflexion de la bilame 40. Le décalage latéral de la cloison 22 au niveau de l'espace 72 correspond sensiblement à la moitié de la largeur du deuxième compartiment 30 de neutre, et permet de conserver les dimensions standards du boîtier 12, avec une chambre d'extinction d'arc dans chaque compartiment de phase 28 et de neutre 30.The length of the
Le calibre maximum d'un tel disjoncteur unipolaire et neutre peut atteindre 45A en conservant l'encombrement latéral du boîtier standard.The maximum rating of such a single-pole, neutral circuit breaker can reach 45A while maintaining the lateral dimensions of the standard box.
Selon la figure 5, une paroi de blindage 80 en matériau métallique est insérée dans la cloison 22 entre les chambres d'extinction d'arc des deux compartiments 28,30. La cloison 22 est alors agencée en deux parties accolées avec interposition de la paroi de blindage 80.La paroi 80 forme un écran entre les deux chambres d'extinction d'arc.According to Figure 5, a
