Definitions
- the invention relates to an adaptation device placed between one of a multiplicity of contactor devices having coupling members performing distinct and substantially rectilinear strokes from which it receives a first movement and a housing of auxiliary switches which is associated with this device to receive a second movement and which has movable contact parts having a working stroke less than or equal to the previous ones.
- This device is suitable when, for a given overall size thereof, certain proportions between the input movement and the output movement must not be exceeded.
- the contactors are called upon to execute working strokes which increase with the size of the currents passing through their main switches.
- the strokes of the auxiliary switches intended to operate electrical interlocks and to retransmit comparable signals are similar, since the loads which they supply always have similar characteristics.
- one of the possible solutions to this problem may consist in the supply of a range of custom-made auxiliary switch devices for the range of corresponding contactors, such a choice is likely to unnecessarily increase the various technical manufacturing costs and management arising from the manufacture of a multiplicity of molds, the management of stocks of multiple parts, etc. Furthermore, it also involves the publication in catalog and the provision of a set of devices including neighboring external forms may cause confusion for the user.
- the invention therefore proposes to overcome the drawbacks of the prior means and to make available to users an adaptation device which will allow mounting on any contactor device of a range, auxiliary switch devices having the size and minimum working strokes required for a combination of these with a contactor device whose nominal rating is the lowest in the range.
- the aim is achieved thanks to the fact that in an envelope of the adaptation device, having suitable indexing means with the body of the associated contactor, is pivoted a transmission lever having, on the one hand , an arm which is provided with a groove in S shape to cooperate with each of the coupling members sliding in said groove and having, on the other hand, an external coupling claw capable of being associated with a control slide belonging to an auxiliary switch device, this groove comprising , between two non-aligned end portions, an intermediate connection portion whose length and orientation are sufficient to communicate to the lever a tilting capable of giving the claw a determined displacement for a fraction of the working stroke of the contactor having the highest working stroke of the range, said end portions not contributing to this tilting of the lever.
- association claw is accessible when the intermediate device is already associated with the body of the contactor, a replacement of the auxiliary switch devices can then be easily operated without the need to disassemble the adaptation device.
- a widening of the functions of the adaptation device can be obtained by means of the installation of several levers in order to have two claws capable of thus actuating a couple of auxiliary devices which can perform distinct functions such as, for example, closing and instantaneous or delayed opening of auxiliary contacts.
- a large-caliber contactor device 1 visible in FIG. 1, includes an internal electromagnet whose non-visible movable armature performs a certain stroke during its excitation and its de-excitation.
- a lateral coupling member such as a pin or nipple 2, being connected directly or not to this armature simultaneously performs a substantially rectilinear displacement of direction F which is used to cause the switching of associated auxiliary switches such as 3 which are , in the context of the present invention, generally intended to be combined with contactors of lower ratings.
- auxiliary switches whose stroke of the moving parts is substantially less than the previous one, could not be coupled to this pin without the putting into service of an appropriate adaptation device such as 4.
- auxiliary switches such as, for example, a timed switch 5
- auxiliary switches can also be combined with the contactor 1 thanks to this same adaptation device when their sizes and the strokes of their moving parts were also initially designed as part of an association with a contactor of lower rating.
- the adaptation device 4 comprises a hollow envelope 6 in which are symmetrically pivoted concentrically about an axis YY ′ two levers 7, 8 substantially identical, but turned 180 °.
- the pivot can advantageously be materialized by a cylindrical rod coming from a part with the envelope.
- Each of the levers such as 7 comprises two perpendicular arms 9, 11 on either side of the common pivot 12, one of these 9 having a claw 15 respectively 16 for example in the form of a dovetail, while the another has a light 20 respectively 30.
- the latter takes the general form of an S, two end portions 17, 18 of which are connected by an intermediate central portion 19.
- This lever can oscillate by a value - alpha -, during a movement whose origin will be described later, and whose amplitude is such that the claw 15 can, for example, engage a certain amount in the internal volume 21 of the envelope for an extreme working position - T -, see Figure 3, while it exceeds by another quantity - e - the surface 22 of the envelope for an opposite extreme position of rest - R - through an opening O, see Figure 1.
- the bottom 23 of the casing 6 has a notch 24 opposite which come the ends 25, 26 of the two levers, while a side wall 27 has two holes 28, 29 placed so precise with respect to the axis XX ′ and with respect to a central oblong opening 31 directed towards this axis.
- This oblong opening has a length - d - which is at least equal to the stroke that the coupling member 2 which can cross it can make when the envelope is precisely associated against the lateral face 32 of the contactor device. .
- the precision of this association which is obtained here thanks to two openings, threaded on this wall such as, for example, 33, 34, see FIG. 1, receiving fixing screws which circulate through the holes 28, 29, can also use other indexing means well known per se.
- the substantially straight stroke of the coupling member 2 is less than the total length of each light so that for each of the rest positions - R - and work - T - clearances - j1 - and - j2 - remain at both ends of the latter for said active and inactive positions of the contactor.
- the angular displacements of the levers occur when the coupling member 2 circulates in the intermediate portion 19 inclined which connects the two non-aligned portions and substantially rectilinear ends.
- the coupling member When, during assembly, and therefore for the de-energized state of the contactor device, the coupling member must be introduced into the two slots of the levers, these can be moved manually through the notch 24 so that s 'more easily establish an alignment allowing this introduction.
- the claw 15 engages around a suitable extension 45 belonging to a control rod 46 of the auxiliary switches, to communicate to the latter a determined movement - e - substantially constant.
- auxiliary switches I1, I2 must perform electrical locking functions, as is the case, for example, in direction-of-travel reversing arrangements for three-phase motors, where it is necessary to prevent overlapping of the periods d 'excitation of the two corresponding electromagnet coils, these two switches can not have simultaneous closing phases.

Description
L'invention se rapporte à un dispositif d'adaptation placé entre l'un d'une multiplicité d'appareils contacteurs ayant des organes d'accouplement effectuant des courses distinctes et sensiblement rectilignes dont il reçoit un premier mouvement et un boîtier d'interrupteurs auxiliaires qui est associé à ce dispositif pour en recevoir un second mouvement et qui présente des pièces de contact mobiles ayant une course de travail inférieure ou égale aux précédentes.The invention relates to an adaptation device placed between one of a multiplicity of contactor devices having coupling members performing distinct and substantially rectilinear strokes from which it receives a first movement and a housing of auxiliary switches which is associated with this device to receive a second movement and which has movable contact parts having a working stroke less than or equal to the previous ones.
On a déjà proposé, par exemple dans le brevet français No FR-A-2617331 de la Demanderesse, un dispositif à came rotative dans lequel la rotation de celle-ci est transmise de façon non linéaire pour ne pas répercuter l'intégralité des mouvements que reçoit ce dispositif.We have already proposed, for example in French patent No FR-A-2617331 of the Applicant, a rotary cam device in which the rotation of the latter is transmitted in a non-linear fashion so as not to reflect all of the movements that receives this device.
Ce dispositif convient lorsque, pour un encombrement déterminé de celui-ci, certaines proportions entre le mouvement d'entrée et le mouvement de sortie ne doivent pas être dépassées.This device is suitable when, for a given overall size thereof, certain proportions between the input movement and the output movement must not be exceeded.
Pour assurer des coupures convenables des arcs, les contacteurs sont appelés à exécuter des courses de travail qui croissent avec le calibre des courants passant par leurs interrupteurs principaux. Par contre, les courses des interrupteurs auxiliaires destinés à opérer des verrouillages électriques et à retransmettre des signalisations comparables sont similaires, puisque les charges qu'elles alimentent présentent toujours des caractéristiques voisines.To ensure proper breaking of the arcs, the contactors are called upon to execute working strokes which increase with the size of the currents passing through their main switches. On the other hand, the strokes of the auxiliary switches intended to operate electrical interlocks and to retransmit comparable signals are similar, since the loads which they supply always have similar characteristics.
Si l'on exclut la mise en oeuvre de dispositions particulières et coûteuses, ces interrupteurs auxiliaires ne pourront donc pas être directement accouplés aux pièces mobiles des appareils contacteurs auxquels on souhaite les associer.If we exclude the implementation of specific and costly arrangements, these auxiliary switches cannot therefore be directly coupled to the moving parts of the contactor devices to which we wish to associate them.
Si l'une des solutions possibles à ce problème peut consister en la fourniture d'une gamme d'appareils interrupteurs auxiliaires fabriqués sur mesure pour la gamme des contacteurs correspondants, un tel choix est de nature à augmenter inutilement les divers frais techniques de fabrication et de gestion découlant de la fabrication d'une multiplicité de moules, de la gestion de stocks de pièces multiples, etc... Par ailleurs, il implique également la publication en catalogue et la mise à disposition d'un ensemble d'appareils dont les formes extérieures voisines risquent de provoquer des confusions chez l'utilisateur.If one of the possible solutions to this problem may consist in the supply of a range of custom-made auxiliary switch devices for the range of corresponding contactors, such a choice is likely to unnecessarily increase the various technical manufacturing costs and management arising from the manufacture of a multiplicity of molds, the management of stocks of multiple parts, etc. Furthermore, it also involves the publication in catalog and the provision of a set of devices including neighboring external forms may cause confusion for the user.
L'invention se propose par suite d'écarter les inconvénients des moyens antérieurs et de mettre à la disposition des utilisateurs un dispositif d'adaptation qui permettra de monter sur tout appareil contacteur d'une gamme, des appareils interrupteurs auxiliaires présentant la taille et les courses de travail minimales requises pour une association de ceux-ci avec un appareil contacteur dont le calibre nominal est le plus bas dans la gamme.The invention therefore proposes to overcome the drawbacks of the prior means and to make available to users an adaptation device which will allow mounting on any contactor device of a range, auxiliary switch devices having the size and minimum working strokes required for a combination of these with a contactor device whose nominal rating is the lowest in the range.
Selon l'invention, le but visé est atteint grâce au fait que dans une enveloppe du dispositif d'adaptation, présentant des moyens d'indexation appropriés avec le corps du contacteur associé, se trouve pivoté un levier de transmission ayant, d'une part, un bras qui est pourvu d'une rainure en forme de S pour coopérer avec chacun des organes d'accouplement coulissant dans ladite rainure et présentant, d'autre part, une griffe d'accouplement externe apte à s'associer à un tiroir de commande appartenant à un appareil interrupteur auxiliaire, cette rainure comportant, entre deux portions d'extrémité non alignées, une portion intermédiaire de raccordement dont la longueur et l'orientation sont suffisantes pour communiquer au levier un basculement propre à conférer à la griffe un déplacement déterminé pour une fraction de la course de travail du contacteur ayant la course de travail la plus élevée de la gamme, lesdites portions d'extrémité ne contribuant pas à ce basculement du levier.According to the invention, the aim is achieved thanks to the fact that in an envelope of the adaptation device, having suitable indexing means with the body of the associated contactor, is pivoted a transmission lever having, on the one hand , an arm which is provided with a groove in S shape to cooperate with each of the coupling members sliding in said groove and having, on the other hand, an external coupling claw capable of being associated with a control slide belonging to an auxiliary switch device, this groove comprising , between two non-aligned end portions, an intermediate connection portion whose length and orientation are sufficient to communicate to the lever a tilting capable of giving the claw a determined displacement for a fraction of the working stroke of the contactor having the highest working stroke of the range, said end portions not contributing to this tilting of the lever.
Une telle disposition présente des avantages supplémentaires si la griffe d'association est accessible lorsque le dispositif intermédiaire est déjà associé au corps du contacteur, une rechange des appareils interrupteurs auxiliaires pouvant alors être aisément opérée sans qu'il soit nécessaire d'effectuer un démontage du dispositif d'adaptation.Such an arrangement has additional advantages if the association claw is accessible when the intermediate device is already associated with the body of the contactor, a replacement of the auxiliary switch devices can then be easily operated without the need to disassemble the adaptation device.
Par ailleurs, un élargissement des fonctions du dispositif d'adaptation peut être obtenu moyennant la mise en place de plusieurs leviers afin de disposer de deux griffes susceptibles d'actionner ainsi un couple d'appareils auxiliaires pouvant exécuter des fonctions distinctes comme, par exemple, la fermeture et l'ouverture instantanée ou retardée de contacts auxiliaires.Furthermore, a widening of the functions of the adaptation device can be obtained by means of the installation of several levers in order to have two claws capable of thus actuating a couple of auxiliary devices which can perform distinct functions such as, for example, closing and instantaneous or delayed opening of auxiliary contacts.
L'invention ainsi que d'autres mesures susceptibles d'en faciliter la mise en oeuvre, ou d'en accroître l'intérêt ou encore de l'adapter à des contacteurs de type particulier seront mieux comprises à la lecture de la description ci-dessous et à l'examen des figures annexées qui l'accompagnent en illustrant:

Un appareil contacteur de gros calibre 1, visible à la figure 1, comporte un électro-aimant interne dont l'armature mobile non visible effectue une certaine course lors de son excitation et de sa désexcitation. Un organe d'accouplement latéral tel qu'une goupille ou téton 2, se trouvant reliée directement ou non à cette armature effectue simultanément un déplacement sensiblement rectiligne de direction F qui est exploité pour provoquer la commutation d'interrupteurs auxiliaires associés tels que 3 qui sont, dans le cadre de la présente invention, généralement destinés à être combinés avec des contacteurs de calibres plus faibles. Ces interrupteurs auxiliaires, dont la course des pièces mobiles est sensiblement inférieure à la précédente, ne pourraient pas être accouplés à cette goupille sans la mise en service d'un dispositif d'adaptation approprié tel que 4.A large-
D'autres types d'interrupteurs auxiliaires, tels que, par exemple, un interrupteur temporisé 5, peuvent également faire l'objet d'une association avec le contacteur 1 grâce à ce même dispositif d'adaptation lorsque leurs tailles et les courses de leurs pièces mobiles ont été également initialement conçues dans le cadre d'une association avec un contacteur de calibre plus faible.Other types of auxiliary switches, such as, for example, a timed
Ainsi qu'on le voit mieux à la figure 3, le dispositif d'adaptation 4 comporte une enveloppe creuse 6 dans laquelle sont symétriquement pivotés de façon concentrique autour d'un axe YY′ deux leviers 7, 8 sensiblement identiques, mais retournés de 180°. Le pivot peut être avantageusement matérialisé par une tige cylindrique venant d'une pièce avec l'enveloppe.As can best be seen in FIG. 3, the
Compte tenu de la taille de l'appareil contacteur, deux leviers ont été ici mis en oeuvre dans une même enveloppe de dimensions adaptées alors qu'un seul levier pourrait être utilisé si cette taille présentait un volume plus réduit, voir fig2.. Chacun des leviers tels que 7 comporte deux bras perpendiculaires 9, 11 de part et d'autre du pivot commun 12, l'un de ceux-ci 9 présentant une griffe 15 respectivement 16 par exemple en forme de queue d'aronde, tandis que l'autre comporte une lumière 20 respectivement 30. Cette dernière prend la forme générale d'un S dont deux portions d'extrémités 17, 18 sont reliées par une portion centrale intermédiaire 19.Given the size of the contactor device, two levers have been implemented here in the same envelope of suitable dimensions whereas a single lever could be used if this size had a smaller volume, see fig2. Each of the levers such as 7 comprises two
Ce levier peut osciller d'une valeur - alpha -, au cours d'un mouvement dont l'origine sera décrite ultérieurement, et dont l'amplitude est telle que la griffe 15 peut, par exemple, s'engager d'une certaine quantité dans le volume interne 21 de l'enveloppe pour une position extrême de travail - T -, voir figure 3, alors qu'elle dépasse d'une autre quantité - e - la surface 22 de l'enveloppe pour une position extrême opposée de repos - R - à travers une ouverture O, voir figure 1. Le fond 23 de l'enveloppe 6 présente une encoche 24 en regard de laquelle viennent se présenter les extrémités 25, 26 des deux leviers, tandis qu'une paroi latérale 27 présente deux trous 28, 29 placés de façon précise par rapport à l'axe XX′ et par rapport à une ouverture oblongue centrale 31 dirigée vers cet axe. Cette ouverture oblongue présente une longueur - d - qui est au moins égale à la course que peut effectuer l'organe d'accouplement 2 qui vient la traverser lorsque l'enveloppe est associée de façon précise contre la face latérale 32 de l'appareil contacteur. La précision de cette association, qui est obtenue ici grâce à deux ouvertures, filetées de cette paroi telles que, par exemple, 33, 34, voir figure 1, recevant des vis de fixation qui circulent au travers des trous 28, 29, peut également faire appel à d'autres moyens d'indexation bien connus en soi.This lever can oscillate by a value - alpha -, during a movement whose origin will be described later, and whose amplitude is such that the
Au cours de leur pivotement, les diverses portions des lumières 20 et 30 se déplacent en regard de l'ouverture oblongue 31.During their pivoting, the various portions of the
Ces déplacements seront obtenus par suite des mouvements sensiblement rectilignes de l'organe d'accouplement 2 entre des positions actives et inactives, lorsque celui-ci aura été introduit dans les deux lumières après avoir traversé l'ouverture oblongue lorsque la paroi 27 de celle-ci est placée contre la face latérale 32. Ces pénétrations sont établies au moment où l'enveloppe 6 est associée avec l'appareil contacteur 1 à l'état de repos, voir figure 2.These displacements will be obtained as a result of substantially rectilinear movements of the
Ainsi qu'on le voit aux figures 2 et 3, la course sensiblement rectiligne de l'organe d'accouplement 2 est inférieure à la longueur totale que présente chaque lumière de sorte que pour chacune des positions de repos - R - et de travail - T - des jeux - j1 - et - j2 - subsistent aux deux extrémités de celles-ci pour lesdites positions actives et inactives du contacteur.As seen in Figures 2 and 3, the substantially straight stroke of the
Ainsi qu'on le constate sur ces deux figures, les déplacements angulaires des leviers se produisent lorsque l'organe d'accouplement 2 circule dans la portion intermédiaire 19 inclinée qui raccorde les deux portions non alignées et d'extrémités sensiblement rectilignes.As can be seen in these two figures, the angular displacements of the levers occur when the
En pratique, il est avantageux de donner à ces portions d'extrémité des directions rectilignes convergentes vers l'axe XX′ pour que les positions de repos et de travail des leviers soient bien déterminées même si l'amplitude de la course de l'organe de commande varie légèrement dans chacune des deux positions active et inactive du contacteur.In practice, it is advantageous to give these end portions rectilinear directions converging towards the axis XX ′ so that the rest and working positions of the levers are well determined even if the amplitude of the stroke of the member slightly varies in each of the two active and inactive positions of the contactor.
Lorsque, au montage, et donc pour l'état désexcité de l'appareil contacteur, l'organe d'accouplement doit être introduit dans les deux lumières des leviers, ceux-ci peuvent être déplacés manuellement à travers l'encoche 24 pour que s'établisse plus aisément un alignement permettant cette introduction.When, during assembly, and therefore for the de-energized state of the contactor device, the coupling member must be introduced into the two slots of the levers, these can be moved manually through the
Une fois associées au contacteur, les différentes pièces mobiles se trouvent à l'état de repos représenté à la figure 1 et le dépassement des griffes 15, 16 permet la mise en place d'un bloc de contact auxiliaire temporisé ou non. Cette mise en place qui est guidée et assurée grâce à des saillies 41, 42 placées extérieurement sur la surface 22 pour s'engager dans des dégagements 43, 44 de formes adaptées, venant avec le boîtier des interrupteurs auxiliaires voir figure 4, s'effectue grâce à un mouvement de sens - G - sensiblement parallèle à la surface 22, voir figure 2.Once associated with the contactor, the various moving parts are in the rest state shown in FIG. 1 and the protrusion of the
Au cours de ce déplacement, la griffe 15 vient s'engager autour d'un prolongement adapté 45 appartenant à une tige de commande 46 des interrupteurs auxiliaires, pour communiquer à celle-ci un déplacement déterminé - e - sensiblement constant.During this movement, the
Si l'on se reporte au diagramme de la figure 5, où l'on a porté en abscisse les courses possibles des armatures de différents appareils contacteurs (ou de pièces de commande qui pourraient leur être directement reliées), et où l'on retrouve en ordonnées les déplacements angulaires des leviers de transmission, on constate que seule une fraction centrale AB de la courbe D est dévolue à l'actionnement des interrupteurs auxiliaires, de sorte que l'on se trouve à l'abri de variations importantes des tolérances de fabrication.If we refer to the diagram in FIG. 5, where we have plotted on the abscissa the possible strokes of the armatures of different contactor devices (or of control parts which could be their connected), and where we find on the ordinate the angular displacements of the transmission levers, we see that only a central fraction AB of the curve D is devoted to the actuation of the auxiliary switches, so that we are at protected from significant variations in manufacturing tolerances.
Ces précautions sont importantes lorsque des interrupteurs auxiliaires I1, I2 doivent effectuer des fonctions de verrouillage électrique, comme le cas se présente par exemple dans les montages inverseurs du sens de marche de moteurs triphasés, où il est nécessaire d'empêcher un chevauchement des périodes d'excitation des deux bobines d'électro-aimant correspondantes, ces deux interrupteurs ne pouvant avoir de phases de fermeture simultanées.These precautions are important when auxiliary switches I1, I2 must perform electrical locking functions, as is the case, for example, in direction-of-travel reversing arrangements for three-phase motors, where it is necessary to prevent overlapping of the periods d 'excitation of the two corresponding electromagnet coils, these two switches can not have simultaneous closing phases.
