Definitions
- the invention relates to a device for interlocking two electrical devices with a miniature molded case according to the preamble of claim 1.
- Modular devices in particular miniature switches or circuit breakers installed in low-voltage power supply boxes, are frequently used for normal emergency power supply, or for supplying two loads, the simultaneous operation of which must be avoided.
- a normal emergency power supply it has already been proposed to couple the control handles of the two devices so as to move these handles in opposite directions, the opening of one of the devices automatically causing the closure of the other and vice versa.
- Manufacturing tolerances prevent the obtaining of a precise point of opening or closing of the device and overlaps, for example causing the simultaneous closing of the two devices for a short time are inevitable.
- Known locks and padlocking systems are also known, preventing the operation of one of the handles when the other handle is not in the closed position, but these devices are unattractive and complicated to handle.
- the present invention aims to allow a simple embodiment of an interlocking module of two electrical devices preventing any simultaneous closing of these two devices or in general the coming of one of the devices in a predetermined position when the other is in a given position.
- the module with a standard profile, for example with a width of 18mm, is interposed between the two devices to be interlocked, by being snapped onto the support rail.
- the general appearance of the switchboard is not modified by the presence of this interlocking system, only the overall width increases slightly.
- the interlocking module has two coaxial connecting shafts projecting laterally from the module, and the ends of which are arranged to fit into a conjugate housing, formed in the pivot axis of the handles of the devices attached to the interlocking module. These ends of polygonal shafts, in particular rectangular ones, can of course cooperate with another part of the mechanism of the apparatus, the position of which is representative of that of the contacts.
- the devices, in particular the switches are of a standard type having the aforementioned housing in the control handle, or any other system for coupling to the interlocking module.
- the module can interlock devices of different ratings and / or with a different number of poles, for example a 10-pole single-pole switch coupled to a 63-amp four-pole switch.
- the functions fulfilled by the coupled devices can also be different, a circuit breaker being for example coupled to a switch or to a switch.
- the interlocking mechanism housed in the module advantageously comprises a slide cooperating with the two connecting shafts, in such a way that the rotation of one of the shafts in the closed position of the associated switch causes the slide to move in a locking position of the other shaft in the opening position of the associated switch and vice versa.
- each end of the connecting shafts carries a cam or half-moon lock housed face to face inside the interlocking module and cooperating with a stop of the slide. In the open position of the two switches, the flat faces of the half-moon locks are parallel and oriented in opposite directions, being framed with play by the two stops carried by the slide.
- the clearance between the half-moons and the stops is sufficient to allow the rotation of one of the half-moons corresponding to a closing of the associated switch. This rotation brings the slide into the locking position of the other switch, the stop of the slide coming to bear on the flat face of the half-moon to prevent any rotation of the latter.
- two miniature devices with molded housing 10,12 for example two switches of the range commercially known as multi 9, are fixed and aligned on a support rail (not shown) with symmetrical profile. Between the switches 10,12 is interposed an interlocking module 14 with molded housing of the same profile as those of the switches 10,12, this housing being snapped in the same way on the support rail.
- the switches 10, 12 are of a standard type having a control lever 16 whose pivoting causes the opening and closing of the contacts of the switch.
- the hub 18 of the lever 16 has an axial recess 20 of rectangular, polygonal or any other suitable section, arranged opposite an orifice 22 formed in the lateral face of the molded housing of the switch.
- the interlocking module 14 comprises two connecting shafts 24, 26 projecting laterally on either side of the molded housing, and mounted for rotation on an axis coinciding with the pivot axis of the levers 16.
- the section of the shafts 24 , 26, in particular the rectangular section is adapted to fit into the recess 20 of the lever 16 of the switch attached to the interlocking module 14.
- Each shaft 24, 26 is mounted for rotation on a flange 28 of the housing, and the end of the shaft, internal to the housing, carries a cam or half-moon lock 30,32.
- the two latches 30, 32 are arranged face to face by framing a slide 34 guided by pins 36, and elongated slots 38 allowing sliding perpendicular to the trees 24, 26.
- Each half-moon lock 30,32 has a cut face 40,42, oriented in the opposite direction, and arranged opposite the stops 44,46 integral with the slide 34.
- the levers 16 and the shafts 24, 26 coupled to these levers are in the position shown in FIGS. 2 and 3, in which the cut faces 40, 42 are parallel and framed with play by the stops 44, 46.
- This clearance is sufficient to authorize the closing of one of the switches 10,12, but it prevents the simultaneous closing of the two switches 10,12 in the manner described below.
- the interlocking device operates as follows: - When the two switches 10,12 are in the open position, the latches 30,32 are in the position shown in Figures 2 and 3 in which the cut faces 40,42 are parallel.
- the slide 34 is either in the middle position shown in the figures, or in abutment with one or the other of the cut faces 40,42.
- Actuation of the joystick 16 of one of the switches, for example of the switch 12 causes the rotation of the connecting shaft 26 in the clockwise direction, which brings the cut face 42 of the latch 32 to the inclined position, shown on Figure 4.
- the rotation of the lock 32 moves or maintains the slide 34 towards the extreme left position, bringing the stop 44 to bear on the cut face 40 of the lock 30.
- the stops 44,46 consist of tabs folded at right angles to the slide 34, but it is clear that the interlocking between the two connecting shafts 24,26 can be achieved in a different way.
- the interlocking module 14 is interposed and attached to the switches 10, 12, and the three modules are secured by any suitable means, in particular by stirrups 50 which snap into recesses of the assembled molded housings.
- the three modules 10,12,14 thus constitute a block snapped onto the support rail, the switches 10,12 being interlocked.
- the same module interlocking device 14 can be coupled to any miniature device of the same profile, in particular to multipole switches 52, 54 as shown in FIG. 8.
- the interlocking device can be associated with standard devices and can if necessary be subsequently installed to ensure interlocking.

Description
L'invention est relative à un dispositif d'interverrouillage de deux appareils électriques à boîtier moulé miniature selon le préambule de la revendication 1.The invention relates to a device for interlocking two electrical devices with a miniature molded case according to the preamble of claim 1.
Les appareils modulaires, notamment les interrupteurs ou disjoncteurs miniatures installés dans les coffrets d'alimentation basse tension, sont fréquemment utilisés pour une alimentation normale secours, ou pour une alimentation de deux charges dont le fonctionnement simultané doit être évité. Dans le cas d'une alimentation normale secours, il a déjà été proposé d'accoupler les manettes de commande des deux appareils de manière à déplacer en sens opposé ces manettes, l'ouverture d'un des appareils provoquant automatiquement la fermeture de l'autre et inversement. Les tolérances de fabrication empêchent l'obtention d'un point précis d'ouverture ou de fermeture de l'appareil et des chevauchements, provoquant par exemple la fermeture simultanée des deux appareils pendant un court instant sont inévitables. On connait également des systèmes de verrous et de cadenassage des manettes, empêchant la manoeuvre de l'une des manettes lorsque l'autre manette n'est pas en position de fermeture, mais ces dispositifs sont inesthétiques et d'un maniement compliqué.Modular devices, in particular miniature switches or circuit breakers installed in low-voltage power supply boxes, are frequently used for normal emergency power supply, or for supplying two loads, the simultaneous operation of which must be avoided. In the case of a normal emergency power supply, it has already been proposed to couple the control handles of the two devices so as to move these handles in opposite directions, the opening of one of the devices automatically causing the closure of the other and vice versa. Manufacturing tolerances prevent the obtaining of a precise point of opening or closing of the device and overlaps, for example causing the simultaneous closing of the two devices for a short time are inevitable. Known locks and padlocking systems are also known, preventing the operation of one of the handles when the other handle is not in the closed position, but these devices are unattractive and complicated to handle.
D'après le document DE-U-8714499 qui décrit un dispositif selon le préambule de la revendication 1, il est également connu d'intercaler, entre deux appareils électriques, un dispositif d'interverrouillage comportant deux liaisons mécaniques qui s'étendent transversalement et relient les deux mécanismeS respectivement associés aux deux appareils électriques. Ces liaisons mécaniques opèrent selon un mouvement de translation et de ce fait requièrent un réglage par vis pour chacune d'elles; en outre elles comportent un nombre important de pièces en mouvement.According to document DE-U-8714499 which describes a device according to the preamble of claim 1, it is also known to interpose, between two electrical devices, an interlocking device comprising two mechanical connections which extend transversely and connect the two mechanisms respectively associated with the two electrical devices. These mechanical connections operate in a translational movement and therefore require adjustment by screw for each of them; in addition they include a large number of moving parts.
La présente invention a pour but de permettre une réalisation simple d'un module d'interverrouillage de deux appareils électriques empêchant toute fermeture simultanée de ces deux appareils ou en général la venue de l'un des appareils en une position prédéterminée lorsque l'autre est dans une position donnée.The present invention aims to allow a simple embodiment of an interlocking module of two electrical devices preventing any simultaneous closing of these two devices or in general the coming of one of the devices in a predetermined position when the other is in a given position.
Le dispositif d'interverrouillage selon l'invention est décrit dans la revendication 1.The interlocking device according to the invention is described in claim 1.
Le module d'un profil standard, par exemple d'une largeur de 18mm est intercalé entre les deux appareils devant être interverrouillés, en étant encliqueté sur le rail de support. L'aspect général du tableau n'est pas modifié par la présence de ce système d'interverrouillage, seul l'encombrement en largeur augmentant légèrement. Le module d'interverrouillage présente deux arbres de liaison coaxiaux faisant saillie latéralement du module, et dont les extrémités sont agencées pour s'emboîter dans un logement conjugué, ménagé dans l'axe de pivotement des manettes des appareils accolés au module d'interverrouillage. Ces extrémités d'arbres polygonales, notamment rectangulaires peuvent bien entendu coopérer avec une autre pièce du mécanisme de l'appareil dont la position est représentative de celle des contacts. Les appareils, notamment les interrupteurs sont d'un type standard présentant le logement précité dans la manette de commande, ou tout autre système d'accouplement au module d'interverrouillage.The module with a standard profile, for example with a width of 18mm, is interposed between the two devices to be interlocked, by being snapped onto the support rail. The general appearance of the switchboard is not modified by the presence of this interlocking system, only the overall width increases slightly. The interlocking module has two coaxial connecting shafts projecting laterally from the module, and the ends of which are arranged to fit into a conjugate housing, formed in the pivot axis of the handles of the devices attached to the interlocking module. These ends of polygonal shafts, in particular rectangular ones, can of course cooperate with another part of the mechanism of the apparatus, the position of which is representative of that of the contacts. The devices, in particular the switches are of a standard type having the aforementioned housing in the control handle, or any other system for coupling to the interlocking module.
Le module peut interverrouiller des appareils de calibres différents et/ou ayant un nombre de pôles différent, par exemple un interrupteur unipolaire de 10 ampères couplé à un interrupteur tétrapolaire de 63 ampères. Les fonctions remplies par les appareils accouplés peuvent également être différentes, un disjoncteur étant par exemple accouplé à un interrupteur ou à un commutateur.The module can interlock devices of different ratings and / or with a different number of poles, for example a 10-pole single-pole switch coupled to a 63-amp four-pole switch. The functions fulfilled by the coupled devices can also be different, a circuit breaker being for example coupled to a switch or to a switch.
Le mécanisme d'interverrouillage logé dans le module comporte avantageusement un coulisseau coopérant avec les deux arbres de liaison, de telle manière que la rotation de l'un des arbres en position de fermeture de l'interrupteur associé, provoque le déplacement du coulisseau dans une position de verrouillage de l'autre arbre en position d'ouverture de l'interrupteur associé et inversement. Par la suite, seule la fermeture simultanée des deux appareils sera évoquée, les autres interverrouillages se déduisant de cette description.
A cet effet, chaque extrémité d'arbres de liaison porte une came ou verrou en demi-lune logé face à face à l'intérieur du module d'interverrouillage et coopérant avec une butée du coulisseau. En position d'ouverture des deux interrupteurs, les faces planes des verrous en demi-lune sont parallèles et orientées en sens opposé, en étant encadrées avec jeu par les deux butées portées par le coulisseau. Le jeu entre les demi-lunes et les butées est suffisant pour permettre la rotation de l'une des demi-lunes correspondant à une fermeture de l'interrupteur associé. Cette rotation amène le coulisseau en position de verrouillage de l'autre interrupteur, la butée du coulisseau venant en appui de la face plane de la demi-lune pour empêcher toute rotation de cette dernière.The interlocking mechanism housed in the module advantageously comprises a slide cooperating with the two connecting shafts, in such a way that the rotation of one of the shafts in the closed position of the associated switch causes the slide to move in a locking position of the other shaft in the opening position of the associated switch and vice versa. Thereafter, only the simultaneous closure of the two devices will be mentioned, the other interlocks deducing from this description.
To this end, each end of the connecting shafts carries a cam or half-moon lock housed face to face inside the interlocking module and cooperating with a stop of the slide. In the open position of the two switches, the flat faces of the half-moon locks are parallel and oriented in opposite directions, being framed with play by the two stops carried by the slide. The clearance between the half-moons and the stops is sufficient to allow the rotation of one of the half-moons corresponding to a closing of the associated switch. This rotation brings the slide into the locking position of the other switch, the stop of the slide coming to bear on the flat face of the half-moon to prevent any rotation of the latter.
Pour assembler le module de verrouillage aux interrupteurs, il suffit de placer les manettes en position appropriée, par exemple en position d'ouverture, et d'amener les arbres de liaison en position correspondante, pour permettre un emboîtement de ces arbres dans des logements correspondants des manettes. Après accolement des boîtiers moulés des interrupteurs au module d'interverrouillage, l'ensemble est avantageusement solidarisé, par exemple par des systèmes de clipsage ou tout autre système de fixation.To assemble the locking module to the switches, it suffices to place the handles in the appropriate position, for example in the open position, and to bring the connecting shafts into the corresponding position, to allow these shafts to be fitted into corresponding housings. joysticks. After joining the molded boxes of the switches to the interlocking module, the assembly is advantageously secured, for example by clipping systems or any other fixing system.

Sur les figures, deux appareils miniatures à boîtier moulé 10,12, par exemple deux interrupteurs de la gamme commercialement dénommée multi 9, sont fixés et alignés sur un rail de support (non représenté) à profil symétrique. Entre les interrupteurs 10,12 est intercalé un module d'interverrouillage 14 à boîtier moulé de même profil que ceux des interrupteurs 10,12, ce boîtier étant encliqueté de la même manière sur le rail de support. Les interrupteurs 10,12 sont d'un type standard ayant une manette de commande 16 dont le pivotement provoque l'ouverture et la fermeture des contacts de l'interrupteur. Le moyeu 18 de la manette 16 présente un évidement axial 20 de section rectangulaire, polygonale ou de toute autre forme appropriée, disposé en regard d'un orifice 22 ménagé dans la face latérale du boîtier moulé de l'interrupteur.In the figures, two miniature devices with molded
Le module d'interverrouillage 14 comporte deux arbres de liaison 24,26 faisant saillie latéralement de part et d'autre du boîtier moulé, et monté à rotation sur un axe coïncidant avec l'axe de pivotement des manettes 16. La section des arbres 24,26, notamment la section rectangulaire est adaptée pour s'emboîter dans l'évidement 20 de la manette 16 de l'interrupteur accolé au module d'interverrouillage 14. Chaque arbre 24,26 est monté à rotation sur un flasque 28 du boîtier, et l'extrémité de l'arbre, interne au boîtier, porte une came ou verrou en demi-lune 30,32. Les deux verrous 30,32 sont disposés face à face en encadrant un coulisseau 34 guidé par des tourillons 36, et des lumières allongées 38 autorisant un coulissement perpendiculairement aux arbres 24,26. Chaque verrou en demi-lune 30,32 présente une face coupée 40,42, orientée en sens opposé, et disposée en regard des butées 44,46 solidaires du coulisseau 34. Dans la position d'ouverture des interrupteurs 10,12, les manettes 16 et les arbres 24,26 accouplés à ces manettes, sont dans la position représentée sur les figures 2 et 3, dans laquelle les faces coupées 40,42 sont parallèles et encadrées avec jeu par les butées 44,46. Ce jeu est suffisant pour autoriser la fermeture de l'un des interrupteurs 10,12, mais il empêche la fermeture simultanée des deux interrupteurs 10,12 de la manière décrite ci-dessous.The
Le dispositif d'interverrouillage fonctionne de la manière suivante:
- lorsque les deux interrupteurs 10,12 sont en position ouvert, les verrous 30,32 sont dans la position représentée sur les figures 2 et 3 dans laquelle les faces coupées 40,42 sont parallèles. Le coulisseau 34 est, soit dans la position médiane représentée sur les figures, soit en butée de l'une ou de l'autre des faces coupées 40,42. L'actionnement de la manette 16 de l'un des interrupteurs, par exemple de l'interrupteur 12, provoque la rotation dans le sens des aiguilles d'une montre de l'arbre de liaison 26, qui amène la face coupée 42 du verrou 32 en position inclinée, représentée sur la figure 4. La rotation du verrou 32 déplace ou maintient le coulisseau 34 vers la position extrème à gauche, amenant la butée 44 en appui de la face coupée 40 du verrou 30. Le coulisseau 34 est immobilisé dans cette position sans jeu par les butées 44,46, et il est facile de voir que la butée 44 empêche toute rotation du verrou 30 et de ce fait, de l'arbre de liaison 24 et de la manette 16 de l'interrupteur 10. En position fermé de l'interrupteur 12, il est donc impossible de faire pivoter la manette 16 de l'interrupteur 10 pour amener ce dernier en position de fermeture. Une ouverture de l'appareil 12 ramène les verrous 30,32 en position initiale représentée à la figure 2, permettant à nouveau une commande de fermeture de l'un quelconque des interrupteurs 10,12. Les figures 6 et 7 illustrent la fermeture de l'appareil 10 qui provoque une rotation du verrou 30, amenant la face coupée correspondante 40 en position inclinée. Ce pivotement provoque le coulissement vers la droite du coulisseau 34, et l'application de la butée 46 contre la face coupée 42 du verrou 32. Cette position symétrique de celle représentée aux figures 4 et 5, correspond à un verrouillage en position ouvert de l'interrupteur 12. Une commande simultanée de fermeture des deux interrupteurs 10,12 est empêchée par le coulisseau 34.The interlocking device operates as follows:
- When the two
Les butées 44,46 sont constituées par des pattes repliées en équerre du coulisseau 34, mais il est clair que l'interverrouillage entre les deux arbres de liaison 24,26 peut être réalisé d'une manière différente. Le module d'interverrouillage 14 est intercalé et accolé aux interrupteurs 10,12, et les trois modules sont solidarisés par tout moyen approprié, notamment par des étriers 50 qui s'encliquètent dans des évidements des boîtiers moulés assemblés. Les trois modules 10,12,14 constituent ainsi un bloc encliqueté sur le rail support, les interrupteurs 10,12 étant interverrouillés. IL est clair que le même module d'interverrouillage 14 peut être accouplé à tout appareil miniature de même profil, notamment à des interrupteurs multipolaires 52,54 de la manière représentée à la figure 8. Le dispositif d'interverrouillage peut être associé à des appareils standards et peut le cas échéant être mis en place ultérieurement pour assurer un interverrouillage.The
L'invention est bien entendu nullement limitée au mode de mise en oeuvre plus particulièrement décrit, mais elle s'étend bien entendu à toute variante de réalisation, notamment à celle dans laquelle les arbres de liaison 24,26 coopéreraient avec une autre pièce du mécanisme de l'interrupteur, dont la position est représentative de celle des contacts, ou celle encore dans laquelle la fermeture de l'un des appareils doit être empêchée lorsque l'autre appareil est ouvert.The invention is of course in no way limited to the mode of implementation more particularly described, but it of course extends to any variant, in particular to that in which the connecting
