Description

L'invention est relative à un mécanisme de commande d'un disjoncteur électrique miniature à boîtier isolant renfermant une paire de contacts fixe et mobile, ledit contact mobile étant porté par un bras de contact actionné par le mécanisme, lequel comporte :

  • une manette de manoeuvre manuelle accouplée à une biellette de transmission pour former une genouillère,
  • un levier support du bras de contact articulé sur un pivot d'une platine rotative, un mouvement relatif de pivotement de faible amplitude étant autorisé entre la platine et le levier support grâce à la présence d'un ressort de pression de contact,
  • une liaison mécanique brisable agencée entre la platine et la biellette de transmission,
  • et un levier de déclenchement articulé sur la platine en étant piloté par le déclencheur pour provoquer en cas de défaut la rupture de ladite liaison mécanique, entraînant le déclenchement automatique du mécanisme, indépendamment de la manette.
The invention relates to a control mechanism for a miniature electric circuit breaker with an insulating housing enclosing a pair of fixed and movable contacts, said movable contact being carried by a contact arm actuated by the mechanism, which comprises:
  • a manual operating lever coupled to a transmission link to form a toggle,
  • a contact arm support lever articulated on a pivot of a rotary plate, a relative swivel movement of small amplitude being authorized between the plate and the support lever thanks to the presence of a contact pressure spring,
  • a breakable mechanical link arranged between the plate and the transmission link,
  • and a trigger lever articulated on the plate being controlled by the trigger to cause in the event of a fault the rupture of said mechanical connection, causing the automatic triggering of the mechanism, independently of the lever.

Un tel dispositif est connu du document EP-A-224.396, dans lequel la liaison mécanique brisable est constituée par une encoche de la platine destinée à coopérer directement avec l'extrémité cylindrique de la biellette en position armée du mécanisme. Un tel mécanisme convient parfaitement pour des disjoncteurs de faibles calibres, mais pour des calibres plus importants, l'effort de déclenchement nécessaire pour briser la liaison mécanique serait trop important, et conduirait à surdimensionner le déclencheur, ce qui est impossible à cause de l'encombrement réduit du boîtier.Such a device is known from document EP-A-224,396, in which the breakable mechanical connection consists of a notch in the plate intended to cooperate directly with the cylindrical end of the link in the armed position of the mechanism. Such a mechanism is perfectly suitable for circuit breakers of low ratings, but for larger ratings, the tripping force required to break the mechanical connection would be too great, and would lead to oversize the trip device, which is impossible because of the reduced overall dimensions of the housing.

Selon les documents EP-A-144.691, DE-A-1.904.731 et DE-U-7500060, un cliquet intermédiaire d'accrochage et le levier de déclenchement du mécanisme sont articulés directement sur le bras de contact. Un tel montage nécessite une grande précision des éléments du mécanisme pour obtenir une bonne pression de contact.According to documents EP-A-144,691, DE-A-1,904,731 and DE-U-7500060, an intermediate catch pawl and the mechanism release lever are articulated directly on the contact arm. Such an assembly requires high precision of the elements of the mechanism to obtain a good contact pressure.

L'objet de l'invention consiste à simplifier la réalisation d'un mécanisme de disjoncteur miniature ayant un effort de déclenchement réduit et une bonne pression de contact.The object of the invention is to simplify the production of a miniature circuit breaker mechanism having a reduced tripping force and a good contact pressure.

Le mécanisme selon l'invention est caractérisé en ce que la liaison mécanique brisable est formée par un cran de retenue du levier de déclenchement coopérant avec un crochet d'accrochage monté à pivotement sur un axe de la platine, et que la biellette de transmission est accouplée au crochet en un point intermédiaire d'articulation situé entre l'axe de la platine et le bec dudit crochet.The mechanism according to the invention is characterized in that the breakable mechanical connection is formed by a notch retaining the trigger lever cooperating with a latching hook pivotally mounted on an axis of the plate, and that the transmission link is coupled to the hook at an intermediate point of articulation situated between the axis of the plate and the spout of said hook.

Le point intermédiaire d'articulation se déplace lors du déclenchement dans une lumière de la platine, ladite lumière borgne ou ouverte étant avantageusement conformée en un secteur circulaire centré sur l'axe du crochet d'accrochage.The intermediate point of articulation moves when triggering in a light of the plate, said blind or open light advantageously being shaped in a circular sector centered on the axis of the hooking hook.

La liaison mécanique à crochet constitue un étage démultiplicateur dans la chaîne cinématique de déclenchement du mécanisme autorisant une réduction de l'effort de déclenchement en provenance du déclencheur magnétothermique.The mechanical hook connection constitutes a multiplier stage in the kinematic chain for triggering the mechanism, allowing a reduction in the tripping force coming from the magnetothermal trigger.

Selon un développement de l'invention, la bilame est reliée au levier de déclenchement par un tiroir rotatif à transmission unidirectionnelle agencé pour constituer une liaison cinématique rigide sans frottement avec le levier de déclenchement lorsque la bilame entraîne le tiroir en cas de déclenchement thermique, ladite liaison étant automatiquement interrompue lorsque la platine est déplacée vers la position d'ouverture des contacts, ou lorsque le percuteur agit sur le levier de déclenchement en cas de déclenchement magnétique.According to a development of the invention, the bimetallic strip is connected to the trigger lever by a rotary drawer with unidirectional transmission arranged to constitute a rigid kinematic connection without friction with the trigger lever when the bimetallic strip drives the drawer in the event of thermal triggering, said link is automatically interrupted when the plate is moved to the open position of the contacts, or when the striker acts on the trigger lever in the event of a magnetic trigger.

Selon un autre développement de l'invention, le crochet d'accrochage du mécanisme coopère après déclenchement avec un point dur d'encliquetage ménagé dans le levier de déclenchement de manière à bloquer le crochet en une position de signalisation de défaut.According to another development of the invention, the hook for hooking the mechanism cooperates after triggering with a hard snap point formed in the trigger lever so as to lock the hook in a fault signaling position.

Deux signalisations d'un défaut après déclenchement sont possibles :

  • l'une directe par le crochet ayant un repère venant en regard avec un voyant du boîtier,
  • l'autre par la manette laquelle est bloquée positivement par la biellette dans une position intermédiaire stable située entre les positions de fermeture et d'ouverture, lorsque le crochet est verrouillé par le point d'encliquetage après déclenchement, le réarmement non automatique du mécanisme s'effectuant par déplacement manuel de la manette de la position intermédiaire vers la position d'ouverture entraînant d'une part, le rétablissement de la liaison mécanique entre la manette et la platine et, d'autre part l'effacement de la signalisation de défaut.
There are two possible indications of a fault after tripping:
  • one direct by the hook having a mark coming opposite with a sight glass of the housing,
  • the other by the lever which is positively locked by the link in a stable intermediate position located between the closed and open positions, when the hook is locked by the latching point after triggering, the non-automatic resetting of the mechanism s '' effecting by manual movement of the lever from the intermediate position to the open position causing, on the one hand, the re-establishment of the mechanical connection between the lever and the plate and, on the other hand, the deletion of the fault signal .

D'autres avantages et caractéristiques ressortiront plus clairement de la description qui va suivre de deux modes de réalisation de l'invention, donnés à titre d'exemples non limitatifs et représentés aux dessins annexés dans lesquels :

  • la figure 1 est une vue schématique d'un premier mode de réalisation de mécanisme selon l'invention, représenté en position de fermeture du disjoncteur;
  • la figure 2 est une vue identique à la figure 1, en position d'ouverture du disjoncteur;
  • la figure 3 est une vue identique à la figure 1 , en position déclenchée sur défaut et manette maintenue;
  • la figure 4 représente une variante de réalisation d'un mécanisme avec indicateur de déclenchement.
Other advantages and characteristics will emerge more clearly from the description which follows of two embodiments of the invention, given by way of nonlimiting examples and represented in the appended drawings in which:
  • Figure 1 is a schematic view of a first embodiment of the mechanism according to the invention, shown in the closed position of the circuit breaker;
  • Figure 2 is a view identical to Figure 1, in the open position of the circuit breaker;
  • Figure 3 is a view identical to Figure 1, in the tripped position on fault and maintained lever;
  • Figure 4 shows an alternative embodiment of a mechanism with trigger indicator.

Sur les figures 1 à 3, le mécanisme 10 de commande d'un disjoncteur électrique miniature à boîtier 12 isolant moulé est du type décrit dans la demande de brevet européen EP-A-224.396 de la demanderesse. Le mécanisme 10 actionne un bras de contact 14 mobile dont l'extrémité libre porte une pièce de contact 16 coopérant avec un contact fixe 18. Une ouverture 20 est ménagée dans la face avant 22 du boîtier 12 pour la passage d'une manette 24 montée à pivotement limite sur un axe 26 entre une position de fermeture (figure 1) dans laquelle les contacts 16,18 sont fermés, et une position d'ouverture (figure 2) correspondant à la séparation des contacts 16,18. La manette 24 est équipée d'une embase interne accouplée à une biellette 28 de transmission pour constituer un dispositif à genouillère 30 dont l'articulation 32 se trouve excentrée par rapport à l'axe 26 fixe de la manette 24.In FIGS. 1 to 3, the mechanism 10 for controlling a miniature electric circuit breaker with molded insulating housing 12 is of the type described in European patent application EP-A-224,396 of the applicant. The mechanism 10 actuates a movable contact arm 14 whose free end carries a contact piece 16 cooperating with a fixed contact 18. An opening 20 is formed in the front face 22 of the housing 12 for the passage of a lever 24 mounted with pivoting limit on an axis 26 between a closed position (Figure 1) in which the contacts 16,18 are closed, and an open position (Figure 2) corresponding to the separation of the contacts 16,18. The handle 24 is equipped with an internal base coupled to a transmission link 28 to constitute a toggle device 30 whose articulation 32 is eccentric relative to the fixed axis 26 of the handle 24.

La manette 24 est sollicitée dans le sens trigométrique vers la position d'ouverture par un ressort de rappel (non représenté). Le contact fixe 18 est solidarisé à la carcasse du déclencheur électromagnétique dont seul le percuteur 34 est représenté sur les figures. Le bras de contact 14 est fixé à un levier support 36 en matériau isolant, articulé sur un pivot 38 d'une platine 40 rotative. En position de fermeture des contacts 14, 16, un ressort de pression de contact (non représente), inséré sur le pivot 38, autorise un mouvement relatif de pivotement de faible amplitude entre la platine 40 et le levier support 36.The lever 24 is urged in a counterclockwise direction towards the open position by a return spring (not shown). The fixed contact 18 is secured to the casing of the electromagnetic trip device of which only the striker 34 is shown in the figures. The contact arm 14 is fixed to a support lever 36 of insulating material, articulated on a pivot 38 of a rotary plate 40. In the closed position of the contacts 14, 16, a contact pressure spring (not shown), inserted on the pivot 38, allows relative pivoting movement of small amplitude between the plate 40 and the support lever 36.

Un levier de déclenchement 42 piloté par le percuteur 34 du déclencheur électromagnétique, et la bilame 44 du déclencheur thermique, est monté à pivotement sur un axe 46 porté par la platine 40 avec un décalage prédéterminé par rapport au pivot 38.A trigger lever 42 controlled by the striker 34 of the electromagnetic trigger, and the bimetallic strip 44 of the thermal trigger, is pivotally mounted on an axis 46 carried by the plate 40 with a predetermined offset relative to the pivot 38.

Une liaison mécanique 48 brisable est ménagée entre la biellette de transmission 28 et la platine 40 d'entraînement du bras de contact 14. En position verrouillée, la liaison 48 autorise la commande manuelle du mécanisme 10 par la manette 24. Le déplacement du levier de déclenchement 42 vers la position déclenchée sous l'action du déclencheur, provoque la rupture momentanée de la liaison mécanique 48, entraînant le déclenchement automatique du mécanisme 10, indépendamment de la manette 24. Le levier de déclenchement 42 est associé à un ressort de rappel (non représenté) destiné à assurer le rétablissement automatique de la liaison mécanique 48 lorsque la manette 24 est actionnée vers la position d'ouverture, suite à un déclenchement du mécanisme 10 sur défaut.A breakable mechanical connection 48 is provided between the transmission link 28 and the plate 40 for driving the arm of contact 14. In the locked position, the link 48 authorizes manual control of the mechanism 10 by the lever 24. The movement of the trigger lever 42 to the triggered position under the action of the trigger, causes the mechanical link 48 to break momentarily, causing the automatic triggering of the mechanism 10, independently of the lever 24. The trigger lever 42 is associated with a return spring (not shown) intended to ensure the automatic re-establishment of the mechanical connection 48 when the lever 24 is actuated towards the position opening, following a trip of mechanism 10 on fault.

Le fonctionnement d'un tel mécanisme de commande est bien connu des spécialistes, et il est inutile de le décrire plus en détails.The operation of such a control mechanism is well known to specialists, and it is unnecessary to describe it in more detail.

Selon l'invention, la liaison mécanique 48 brisable comporte un crochet 50 d'accrochage monté à pivotement sur un axe 52 de la platine 40. A l'opposé de l'axe 52, le bec du crochet 50 coopère en position verrouillée de la liaison 48 avec un cran 54 de retenue situé sur le bras supérieur du levier de déclenchement 42.According to the invention, the breakable mechanical link 48 comprises a hook 50 for hooking pivotally mounted on an axis 52 of the plate 40. Opposite the axis 52, the beak of the hook 50 cooperates in the locked position of the link 48 with a retaining notch 54 located on the upper arm of the trigger lever 42.

La biellette de transmission 28 est accouplée au crochet 50 en un point 56 d'articulation susceptible de se déplacer lors du déclenchement dans une lumière 58 de la platine 40. La lumière 58 est borgne ou ouverte, et est conformée en un secteur circulaire centré sur l'axe 52. Le point intermédiaire d'articulation 56 est situé entre l'axe 52 et le bec du crochet 50 d'accrochage. La liaison 48 constitue un étage démultiplicateur dans la chaîne cinématique du mécanisme 10, autorisant une réduction de l'effort de déclenchement en provenance du déclencheur magnétothermique.The transmission link 28 is coupled to the hook 50 at a point 56 of articulation capable of moving when tripping in a light 58 of the plate 40. The light 58 is blind or open, and is shaped in a circular sector centered on the axis 52. The intermediate point of articulation 56 is located between the axis 52 and the spout of the hook 50 for attachment. The link 48 constitutes a step-down stage in the kinematic chain of the mechanism 10, allowing a reduction in the tripping force coming from the magnetothermal trigger.

La bilame 44 du déclencheur thermique coopère avec le levier de déclenchement 42 au moyen d'un tiroir rotatif 60 à transmission unidirectionnelle (voir figures 1 et 2). Le tiroir 60 est formé par un levier coudé ayant une extrémité accouplée librement ou bras inférieur du levier de déclenchement 42 en un point d'articulation 62. La partie intermédiaire incurvée du levier de transmission prend appui sur un bossage 64 du levier de déclenchement 42 de manière a entraîner ce dernier vers la position déclenchée lors de la déflexion vers la droite de la bilame 44 en cas de circulation d'un courant de surcharge dans le pôle. Pendant cette phase de déclenchement thermique, le tiroir 60 constitue une liaison cinématique rigide entre la bilame 44 et le levier de déclenchement 42. L'absence de frottement parasite entre le tiroir 60 et le levier de déclenchement 42 permet une diminution notable de l'effort de déclenchement transmis par la bilame 44. Le point d'articulation 62 est disposé entre le bossage 64 et l'axe 46 de pivotement du levier de déclenchement 42.The bimetallic strip 44 of the thermal trip device cooperates with the trip lever 42 by means of a rotary slide 60 with unidirectional transmission (see FIGS. 1 and 2). The drawer 60 is formed by a bent lever having a freely coupled end or lower arm of the trigger lever 42 at a point of articulation 62. The curved intermediate part of the transmission lever bears on a boss 64 of the trigger lever 42 so as to cause the latter to the triggered position during the deflection towards the right of bimetallic strip 44 in the event of an overload current flowing in the pole. During this thermal tripping phase, the drawer 60 constitutes a rigid kinematic connection between the bimetallic strip 44 and the tripping lever 42. The absence of parasitic friction between the drawer 60 and the tripping lever 42 allows a significant reduction in the effort of the trigger transmitted by the bimetallic strip 44. The articulation point 62 is disposed between the boss 64 and the pivot axis 46 of the trigger lever 42.

Lorsque le mécanisme 10 est actionné manuellement ou automatiquement vers la position d'ouverture, l'extrémité 66 du tiroir 60 à l'opposé du point d'articulation 62, est susceptible de venir en butée contre une protubérance du boîtier 12, avec rupture de la liaison cinématique avec le levier de déclenchement 42. La platine 40 peut pivoter autour du pivot 38 dans le sens trigométrique, et la zone intermédiaire du tiroir 60 se trouve écartée du bossage 64 (figure 2). On remarque que si la liaison restait rigide entre le tiroir 60 et le levier de déclenchement 42, l'ouverture totale du mécanisme 10 serait rendue impossible.When the mechanism 10 is actuated manually or automatically towards the open position, the end 66 of the drawer 60 opposite the articulation point 62, is capable of abutting against a protuberance of the housing 12, with rupture of the kinematic connection with the trigger lever 42. The plate 40 can pivot around the pivot 38 in the counterclockwise direction, and the intermediate zone of the drawer 60 is spaced from the boss 64 (FIG. 2). Note that if the connection remained rigid between the drawer 60 and the trigger lever 42, the complete opening of the mechanism 10 would be made impossible.

Le point d'articulation 62 du tiroir 60 pourrait bien entendu être confondu avec l'axe 46 de pivotement du levier de déclenchement 42.The articulation point 62 of the drawer 60 could of course be merged with the pivot axis 46 of the trigger lever 42.

En cas de déclenchement magnétique suite à un court-circuit, le percuteur 34 du déclencheur électromagnétique agit sur le bras inférieur du levier de déclenchement 42 pour assurer le déverrouillage du crochet 50 d'accrochage par échappement du cran 54 de retenue. Le levier de déclenchement 42 est ainsi déplacé vers la position déclenchée dans le sens trigométrique, sans aucune réaction de freinage du tiroir 60 de déclenchement thermique qui reste inactif grâce à la présence de la liaison souple avec la bilame 44.In the event of a magnetic trip following a short circuit, the striker 34 of the electromagnetic trip device acts on the lower arm of the trip lever 42 to ensure the unlocking of the hook 50 for hooking by escaping the retaining notch 54. The trigger lever 42 is thus moved to the triggered position in the counterclockwise direction, without any braking reaction of the thermal trigger drawer 60 which remains inactive thanks to the presence of the flexible connection with the bimetallic strip 44.

La figure 3 montre le mécanisme 10 après déclenchement sur défaut, la manette 24 étant maintenue manuellement dans la position de droite, à l'encontre de la force de rappel de son ressort. Cette position de la manette 24 correspond à la position de fermeture de la figure 4, mais la biellette 28 ne permet pas le rétablissement de la liaison mécanique 48 du crochet 50 avec le cran 54 du levier de déclenchement 42, et le mécanisme 10 reste déclenché. La liaison mécanique 48 se rétablit automatiquement dès que l'action de verrouillage manuel de la manette 24 est relâchée.FIG. 3 shows the mechanism 10 after tripping on a fault, the handle 24 being held manually in the right position, against the return force of its spring. This position of the lever 24 corresponds to the closed position of FIG. 4, but the link 28 does not allow the reestablishment of the mechanical connection 48 of the hook 50 with the notch 54 of the trigger lever 42, and the mechanism 10 remains triggered . The mechanical link 48 is re-established automatically as soon as the manual locking action of the lever 24 is released.

Selon la variante du mécanisme 100 de la figure 4, les mêmes numéros de repères seront utilisés pour désigner des pièces analogues à celles du mécanisme 10 des figures 1 à 3. En plus de ses deux positions extrèmes d'ouverture et de fermeture, la manette 24 basculante peut occuper une position intermédiaire stable (cas de la figure 4) après déclenchement sur défaut thermique ou magnétique. Le levier de déclenchement 42 comporte un point dur 102 d'encliquetage susceptible de bloquer le crochet d'accrochage 50 après déclenchement et rupture de la liaison mécanique 48. A l'opposé du bec se trouve un repère 104 coloré destiné à signaler la position déclenchée du crochet 50 à travers un voyant 106 de signalisation ménagé dans la face avant 22 du boîtier 12. Le blocage du crochet 50 par le point d'encliquetage 102 permet de signaler le défaut en permanence, d'une part par le voyant 106 et d'autre part par la manette 24 qui occupe la position stable intermédiaire. La fonction indicateur de défaut est ainsi intégrée dans le disjoncteur.According to the variant of the mechanism 100 of FIG. 4, the same reference numbers will be used to designate parts similar to those of the mechanism 10 of FIGS. 1 to 3. In addition to its two extreme opening and closing positions, the lever 24 tilting can occupy a stable intermediate position (case of Figure 4) after tripping on thermal or magnetic fault. The trigger lever 42 includes a hard snap point 102 capable of blocking the hook 50 after triggering and breaking of the mechanical link 48. Opposite the spout is a colored marker 104 intended to signal the triggered position of the hook 50 through a signaling light 106 formed in the front face 22 of the housing 12. The blocking of the hook 50 by the snap point 102 makes it possible to permanently signal the fault, firstly by the light 106 and d 'other hand by the lever 24 which occupies the intermediate stable position. The fault indicator function is thus integrated into the circuit breaker.

Le rearmement non automatique du mécanisme 100 s'effectue par déplacement manuel de la manette 24 dans le sens trigonométrique à partir de la position intermédiaire vers la position d'ouverture (voir flêche R), entraînant le rétablissement de la liaison mécanique 48 entre la manette 24 et la platine 40, et le retour du mécanisme 100 dans l'état appareil ouvert de la figure 2. La signalisation du défaut disparaît, et l'appareil est prêt à être refermé par pivotement de la manette 24 vers la position de fermeture (figure 1).The non-automatic rearming of the mechanism 100 is carried out by manual movement of the lever 24 in a counterclockwise direction from the intermediate position to the open position (see arrow R), causing the restoration of the mechanical connection 48 between the lever 24 and the plate 40, and the return of the mechanism 100 to the open device state of FIG. 2. The fault signal disappears, and the device is ready to be closed by pivoting the lever 24 towards the closed position (figure 1).
