  • and means for authorizing the joining of the boxes in accordance with the state of the mechanisms.

Les blocs auxiliaires utilisés dans l'art antérieur possèdent des manettes saillantes et visibles, et il est facile de vérifier visuellement leurs positions par rapport à celles du disjoncteur. Le problème est différent pour des blocs auxiliaires n'ayant pas de manettes accessibles. Dans ce cas, l'élément d'actionnement du mécanisme est intégré dans le boítier et doit pouvoir être accouplé au disjoncteur ou à d'autres blocs auxiliaires. L'association s'effectue en aveugle avec des risques de montage incorrect en cas de discordance d'état des mécanismes.The auxiliary blocks used in the prior art have projecting levers and visible, and it's easy to visually check their positions relative to those of the circuit breaker. The problem is different for auxiliary blocks having no accessible joysticks. In this case, the actuating element of the mechanism is integrated in the box and must be able to be coupled to the circuit breaker or other auxiliary blocks. The association is carried out blind with mounting risks incorrect in the event of a mismatch in the state of the mechanisms.

Le document DE-U-9302254 conceme l'association d'un disjoncteur avec un module de signalisation destiné à indiquer un défaut de surintensité ou un défaut de court-circuit lors du déclenchement du disjoncteur. L'accouplement modulaire des deux boítiers s'effectue par l'intermédiaire de liaisons mécaniques, dont l'une est reliée au verrou de déclenchement, et dont l'autre est reliée à l'organe de commutation. Un défaut de surintensité est signalé électriquement par un voyant lumineux, tandis qu' un défaut de court-circuit est indiqué en plus par un indicateur mécanique constitué par un bouton en saillie sur la face avant. L'enfoncement du bouton de signalisation permet de réarmer l'appareil. La position haute ou basse de l'indicateur mécanique permet de vérifier visuellement l'état du mécanisme du module par rapport à celui du disjoncteur. L'objet de l'invention consiste à réaliser un bloc auxiliaire de signalisation ou de déclenchement permettant une association fiable en concordance d'état avec un disjoncteur ou un autre bloc auxiliaire.Document DE-U-9302254 relates to the association of a circuit breaker with a signaling module intended to indicate an overcurrent fault or a fault of short circuit when the circuit breaker trips. The modular coupling of two housings is carried out by means of mechanical connections, one of which is connected to the trigger lock, and the other of which is connected to the switching. An overcurrent fault is signaled electrically by an indicator luminous, while a short circuit fault is additionally indicated by an indicator mechanical consisting of a button projecting from the front face. The sinking of the signaling button resets the device. The high or low position of the mechanical indicator allows to visually check the state of the mechanism of the module compared to that of the circuit breaker. The object of the invention is to provide an auxiliary signaling or trigger allowing a reliable association in state agreement with a circuit breaker or other auxiliary unit.

The auxiliary unit according to the invention is characterized in that the element actuator is provided with an access key, and that said second orifice comprises a groove arranged in a lock allowing the passage of the key in the single open position of the actuating element, the fitting of the tab drive in the first or second female coupling member intervening when the mechanism of the adjacent circuit breaker or auxiliary block is itself in the same open state.

Selon un mode de réalisation préférentiel, la serrure est formée par une saignée pratiquée à l'extrémité du deuxième orifice curviligne. La clé comporte une butée destinée à venir en engagement contre le boítier adjacent pour interdire l'accolement des blocs lorsque le mécanisme correspondant n'est pas l'état ouvert.According to a preferred embodiment, the lock is formed by a groove made at the end of the second curvilinear opening. The key has a stop intended to come into engagement against the adjacent box to prohibit the joining blocks when the corresponding mechanism is not the open state.

Sur les figures 1 à 5. un bloc auxiliaire 10 de signalisation ou de déclenchement est accolé à la face transversale 12 d'un disjoncteur 14 avec accouplement d'une liaison mécanique de déclenchement, et d'une liaison d'entraínement des manettes. Le bloc auxiliaire 10 est logé dans un boitier 16 en matière plastique moulée ayant un profil identique à celui du boítier 18 du disjoncteur 14.In FIGS. 1 to 5. an auxiliary block 10 for signaling or tripping is attached to the transverse face 12 of a circuit breaker 14 with coupling of a link mechanical trigger, and a drive linkage of the joysticks. The block auxiliary 10 is housed in a casing 16 of molded plastic having a profile identical to that of the case 18 of the circuit breaker 14.

Le bloc auxiliaire 10 est dépourvu de manette apparente et est composé de deux circuits inverseurs, comprenant chacun un contact mobile coopérant avec deux contacts fixes connectés à une paire de bornes de raccordement. Le contact mobile est actionné au moyen d'un mécanisme de commande, dont seul l'élément d'actionnement en manoeuvre manuelle 20 est représenté sur les figures 3 à 5.Auxiliary unit 10 has no visible handle and is made up of two change-over circuits, each comprising a movable contact cooperating with two fixed contacts connected to a pair of connection terminals. The mobile contact is actuated by means of a control mechanism, of which only the actuating element in manual operation 20 is shown in FIGS. 3 to 5.

L'élément d'actionnement 20 du bloc auxiliaire 10 est formé par une embase 22 rotative intégrée à l'intérieur du boítier 16, et ayant un débattement angulaire limité correspondant à la course de la manette 24 du disjoncteur 14 entre la position d'ouverture et la position de fermeture. L'embase 22 est équipée d'une patte d'entraínement 26 faisant saillie du boítier 16, et disposée en regard d'un orifice 28 curviligne ménagé dans la face transversale 12 du disjoncteur 14. L'extrémité de la patte d'entraínement 26 est conformée selon une clé 30, et la partie droite de l'orifice 28 présente une saignée 32 de forme conjuguée à la clé 30 de manière à constituer une serrure (figure 2). Le support 34 pivotant de la manette 24 du disjoncteur 14 comporte un premier organe d'accouplement 36 femelle se déplaçant le long de l'orifice 28 à l'intérieur du boítier 18. La patte d'entraínement 26 mâle de l'élément d'actionnement 20 s'engage dans le premier accouplement 36 femelle pour former la liaison d'entraínement entre le bloc auxiliaire 10 et le disjoncteur 14. The actuating element 20 of the auxiliary unit 10 is formed by a base 22 rotary integrated inside the housing 16, and having a limited angular movement corresponding to the stroke of the handle 24 of the circuit breaker 14 between the position opening and closing position. Base 22 is fitted with a tab drive 26 projecting from the housing 16, and disposed opposite an orifice 28 curvilinear formed in the transverse face 12 of the circuit breaker 14. The end of the drive tab 26 is shaped according to a key 30, and the right part of the orifice 28 has a groove 32 of form conjugated with the key 30 so as to constitute a lock (Figure 2). The support 34 pivoting of the handle 24 of the circuit breaker 14 comprises a first female coupling member 36 moving along the orifice 28 inside the housing 18. The male drive tab 26 of the element actuator 20 engages in the first female coupling 36 to form the drive link between the auxiliary unit 10 and the circuit breaker 14.

La localisation de la saignée 32 correspond à la position d'ouverture du disjoncteur 14, et la clé 30 ne peut pénétrer complètement dans l'orifice 28 qu'au niveau de la saignée 32.The location of the groove 32 corresponds to the opening position of the circuit breaker 14, and the key 30 can only fully penetrate the orifice 28 at the level of the bloodletting 32.

Une première condition d'accouplement consiste à placer l'élément d'actionnement 20 dans la position d'ouverture du bloc auxiliaire 10, de manière à positionner la clé 30 en regard de la saignée 32. Si le bloc auxiliaire 10 se trouve dans une autre position , par exemple en position de fermeture, toute tentative d'association au disjoncteur 14, est rendue impossible suite à la venue en engagement de l'extrémité 33 de la clé 30 du boítier 14.A first coupling condition consists in placing the actuating element 20 in the open position of the auxiliary unit 10, so as to position the key 30 opposite the groove 32. If the auxiliary unit 10 is in another position, for example in the closed position, any attempt to associate with the circuit breaker 14, is made impossible following the arrival in engagement of the end 33 of the key 30 of the housing 14.

La deuxième condition d'accouplement consiste à placer le premier organe d'accouplement 36 femelle en alignement avec la saignée 32 de l'orifice 28, ce qui n'est possible qu'en position d'ouverture du disjoncteur 14. La patte d'entraínement 26 peut alors pénétrer dans la premier organe d'accouplement 36 dans la sens de la flèche F1 (figure 4) pour constituer la liaison d'entraínement lorsque le disjoncteur 12 et le bloc auxiliaire 10 sont accolés par leurs faces respectives. Si le mécanisme du disjoncteur 14 est dans l'état fermé ou dans l'état déclenché, la clé 30 peut pénétrer dans la saignée 32 de la serrure, mais vient en butée contre le chant 38 du support 34 de la manette 24 en empêchant tout emboítement dans le premier organe d'accouplement 36 (figure 5). Il en résulte un écartement latéral entre les deux boítiers 18, 16 du disjoncteurs 14 et du bloc auxiliaire 10, signalant à l'installateur l'erreur de manipulation, et la discordance des états entre les deux modules.The second mating condition is to place the first organ 36 female coupling in alignment with the groove 32 of the port 28, which is only possible in the open position of the circuit breaker 14. The drive tab 26 can then enter the first coupling member 36 in the direction of the arrow F1 (Figure 4) to form the drive link when the circuit breaker 12 and the auxiliary unit 10 are joined by their respective faces. If the mechanism of circuit breaker 14 is in the closed or tripped state, the key 30 can penetrate in the groove 32 of the lock, but abuts against the edge 38 of the support 34 of the lever 24 by preventing any nesting in the first member coupling 36 (Figure 5). This results in a lateral spacing between the two boxes 18, 16 of circuit breakers 14 and auxiliary unit 10, signaling to the installer the handling error, and the mismatch of the states between the two modules.

L'association entre deux ou plusieurs blocs auxiliaires 10 de signalisation ou de déclenchement s'effectue avec des moyens d'accouplement similaires à ceux utilisés pour le disjoncteur 14, et avec des moyens additionnels de détrompage empêchant certaines combinaisons. A l'opposé de la patte d'entraínement 26, l'embase 22 rotative de l'élément d'actionnement 20 de chaque bloc auxiliaire 10, comporte un deuxième organe d'accouplement 40 femelle (figures 3 à 5), ayant une forme similaire à celle du premier organe d'accouplement 36 du disjoncteur 14. Le deuxième organe d'accouplement 40 se déplace le long d'un orifice 42 curviligne ménagé dans la face latérale 44 de gauche du boítier 10 (figure 1). L'office 42 est équipée d'une saignée 32 de forme identique à celle de l'orifice 28 de la face 12 du disjoncteur 14, et disposée en alignement avec elle dans la direction d'accolement des modules. Pour l'association de deux blocs auxiliaires 10, les mêmes conditions d'accouplement sont applicables pour la formation de la liaison d'entraínement entre les mécanismes respectifs des deux blocs. Les deux mécanismes doivent être simultanément dans l'état ouvert de manière à autoriser l'enfoncement de la clé 30 de l'un des modules dans la saignée 32 de la serrure adjacente, et dans le deuxième organe d'accouplement 40 de l'autre module.The association between two or more auxiliary blocks 10 for signaling or triggering is carried out using coupling means similar to those used for circuit breaker 14, and with additional polarizing means preventing certain combinations. Opposite the drive tab 26, the base 22 of the actuating element 20 of each auxiliary unit 10, comprises a second female coupling member 40 (FIGS. 3 to 5), having a similar shape to that of the first coupling member 36 of the circuit breaker 14. The second member coupling 40 moves along a curvilinear orifice 42 formed in the face lateral 44 on the left of the housing 10 (Figure 1). Office 42 is equipped with a groove 32 of identical shape to that of the orifice 28 of the face 12 of the circuit breaker 14, and arranged in alignment with it in the joining direction of the modules. For the association of two auxiliary blocks 10, the same coupling conditions are applicable for the formation of the drive link between the mechanisms respective of the two blocks. The two mechanisms must be simultaneously in the state open so as to allow the key 30 of one of the modules to be inserted into the groove 32 of the adjacent lock, and in the second coupling member 40 of the other module.

Les figures 6 à 9 montrent l'association de deux blocs auxiliaires 10 A de signalisation OF (ouvert/fermé) ou SD (signal défaut), chaque boítier 16 ayant une largeur de 9 mm.Figures 6 to 9 show the association of two 10 A auxiliary blocks of OF (open / closed) or SD (fault signal) signaling, each box 16 having a width of 9 mm.

On remarque en saillie sur la face latérale 46 de droite de chaque bloc auxiliaire 10A, la patte d'entraínement 26, un téton de déclenchement 48, une paire d'organes de clipsage 50, 52, un premier centreur mâle 54, et un premier orienteur mâle 56. La patte d'entraínement 26 traverse un orifice 58 de forme similaire et aligné avec celui 42 de l'autre face 44, mais dépourvu de serrure. Le téton de déclenchement 48 s'engage dans le levier de déclenchement du module adjacent pour constituer la liaison mécanique de déclenchement. Les organes de clipsages 50, 52 sont formées par des pattes élastiques d'accrochage destinées à s'encliqueter dans des alvéoles du boítier adjacent. Le premier centreur mâle 54 comprend une tige tubulaire agencée à la partie supérieure du boítier 16, tandis que le premier orienteur mâle 56 est doté d'un plot semi-cylindrique prévu à la partie inférieure du boítier 16 au voisinage au voisinage du rail de fixation.There is a protrusion on the right side face 46 of each auxiliary unit 10A, the drive tab 26, a trigger stud 48, a pair of clipping 50, 52, a first male centering device 54, and a first male orienting device 56. The drive tab 26 passes through an orifice 58 of similar shape and aligned with that 42 on the other side 44, but lacking a lock. The trigger nipple 48 engages in the trigger lever of the adjacent module to constitute the mechanical trigger link. The clips 50, 52 are formed by elastic hooking lugs intended to snap into cells of the adjacent housing. The first male centering device 54 comprises a tubular rod arranged at the upper part of the housing 16, while the first male orienter 56 is provided a semi-cylindrical stud provided in the lower part of the housing 16 in the vicinity at near the fixing rail.

La face latérale opposée 44 de gauche de chaque bloc auxiliaire 10A est pourvue en plus de l'orifice 42, d'un premier centreur femelle 60, et d'un premier orienteur femelle 62. Le premier centreur femelle 60 permet l'emboítement de la tige tubulaire du premier centreur mâle 54 pour obtenir un blocage multidirectionnel dans la plan de jonction des deux boítiers. Le premier orienteur femelle 62 est doté d'une encoche en U à la partie inférieure de la face 44 permettant un léger jeu de l'orienteur mâle 56 dans la direction de l'encoche.The opposite side face 44 of the left side of each auxiliary unit 10A is provided with more than the orifice 42, a first female centering device 60, and a first orienter female 62. The first female centralizer 60 allows the fitting of the tubular rod of the first male centering device 54 to obtain a multidirectional blocking in the plane of junction of the two boxes. The first female orienter 62 has a notch in U at the lower part of the face 44 allowing a slight play of the male orienter 56 in the direction of the notch.

Les figures 10 à 13 représentent l'association d'un bloc auxiliaire 10 A de signalisation avec un bloc auxiliaire 10B de déclenchement, ce dernier ayant une largeur de 18 mm. Le bloc auxiliaire 10A de signalisation est placé obligatoirement à gauche du bloc auxiliaire 10B de déclenchement, ce dernier pouvant être constituée par un déclencheur MN à manque de tension, ou un déclencheur MX à émission de courant, destiné à transmettre un ordre de déclenchement au disjoncteur 14. Le bloc auxiliaire 10A de signalisation est identique à celui décrit en référence aux figures 6 à 9, et comporte les premiers centreurs mâle et femelle 54, 60, et les premiers orienteurs mâle et femelle 56, 62.Figures 10 to 13 show the association of an auxiliary block 10 A of signaling with an auxiliary trigger block 10B, the latter having a width of 18 mm. The auxiliary signal block 10A must be placed at left of the auxiliary trigger block 10B, which can be made up by an undervoltage release MN, or an emission release MX current, intended to transmit a trip order to circuit breaker 14. The block signaling auxiliary 10A is identical to that described with reference to FIGS. 6 to 9, and comprises the first male and female centralizers 54, 60, and the first male and female counselors 56, 62.

La face latérale de droite 66 du bloc auxiliaire 10B de déclenchement comporte des organes de clipsage 50, 52, un téton de déclenchement 48, une patte d'entraínement 26 traversant un orifice 58, Un deuxième centreur mâle 68, et un deuxième orienteur mâle 70. Le deuxième centreur mâle 68 et le deuxième orienteur mâle 70 sont formés par des plots cylindriques faisant saillie de la face latérale 66.The right side face 66 of the auxiliary trigger block 10B includes clips 50, 52, a trigger pin 48, a drive tab 26 passing through an orifice 58, a second male centering device 68, and a second orienter male 70. The second male centering device 68 and the second male orienting device 70 are formed by cylindrical studs projecting from the lateral face 66.

La face latérale de gauche 72 du bloc auxiliaire 10B est pourvu en plus de l'orifice 42, d'un deuxième centreur femelle 74, et d'un deuxième orienteur femelle 76. Le deuxième centreur femelle 74 est placé au même endroit que le premier centreur femelle 60, et peut recevoir le premier centreur mâle 54, si le bloc auxiliaire 10A de signalisation est juxtaposé à gauche du bloc auxiliaire 10B de déclenchement (cas de la figure 12).The left side face 72 of the auxiliary unit 10B is provided in addition with the orifice 42, a second female centering device 74, and a second female orienting device 76. The second female centering device 74 is placed in the same place as the first centering device female 60, and can receive the first male centering device 54, if the auxiliary unit 10A of signaling is juxtaposed to the left of the auxiliary trigger block 10B (case of Figure 12).

L'inverse est impossible en cas de tentative de juxtaposition du bloc auxiliaire 10A à droite, car le deuxième centreur mâle 68 ne peut s'engager dans le premier centreur femelle 60. La dimension du deuxième orienteur mâle 70 l'empêche également de pénétrer dans la premier orienteur femelle 62.The reverse is impossible if an attempt is made to juxtapose the auxiliary block 10A with right, because the second male centering device 68 cannot engage in the first centering device female 60. The size of the second male orienter 70 also prevents it from penetrate the first female orienter 62.

Les figures 14 à 16 montrent l'association d'un bloc auxiliaire 10A de signalisation avec le disjoncteur 14. Le bloc auxiliaire 10A de signalisation est identique à celui décrit précédemment, et comporte les premiers centreurs mâle et femelle 54, 60 et les premiers orienteurs mâle et femelle 56, 62. La face latérale 12 du disjoncteur 14 est équipée d'un troisième centreur femelle 78, et d'un troisième orienteur femelle 80.Figures 14 to 16 show the association of an auxiliary signal block 10A with circuit breaker 14. Auxiliary signal block 10A is identical to that described above, and comprises the first male and female centralizers 54, 60 and the first male and female orienters 56, 62. The lateral face 12 of the circuit breaker 14 is equipped with a third female centering device 78, and a third female centering device 80.

Le troisième centreur femelle 78 peut recevoir le premier centreur mâle 54, mais aussi le deuxième centreur mâle 68. Il en est de même du troisième orienteur femelle 80 dans lequel peut s'engager le premier orienteur mâle 56, ou le deuxième orienteur mâle 70. Il est donc possible d'associer la combinaison de la figure 10 à la face 12 du disjoncteur.The third female centering device 78 can receive the first male centering device 54, but also the second male centering device 68. It is the same for the third female centering device 80 in which the first male guide 56, or the second guide can engage male 70. It is therefore possible to associate the combination of FIG. 10 with the face 12 of the breaker.

Par contre, les blocs auxiliaires de signalisation 10A ne peuvent jamais être intercalés entre un bloc auxiliaire 10B de déclenchement, et le disjoncteur 14.On the other hand, the auxiliary signaling blocks 10A can never be inserted between an auxiliary trip block 10B, and the circuit breaker 14.
