L'invention s'applique notamment aux relais de surcharge à réarmement dit "manuel-auto". The invention applies in particular to overload relays with reset called "manual-auto".
Description
La présente invention concerne un dispositif pour l'interdiction sélective et/ou partielle d'un ou plusieurs modes d'actionnement d'organes manuels de commande équipant un appareil.The present invention relates to a device for the selective and / or partial prohibition of one or more modes of actuation of manual control members fitted to an apparatus.
Elle s'applique avantageusement, mais non exclusivement, à des appareils du type relais de surcharge à réarmement manuel et automatique généralement appelés "relais thermiques à réarmement manuel-auto".It applies advantageously, but not exclusively, to devices of the overload relay type with manual and automatic reset generally called "thermal relays with manual-auto reset".
On rappelle à ce sujet qu'un relais thermique est un appareil de protection associé à un contacteur. Il a pour but de surveiller le courant circulant dans la charge (par exemple d'un moteur), commandée par le contacteur et de provoquer l'ouverture de ce dernier en cas de surchage, c'est-à-dire pour un courant pouvant par exemple présenter une valeur comprise entre 1,05 et 1,2 fois le coutant nominal de la charge dont la valeur est indiquée par le constructeur.On this subject, it is recalled that a thermal relay is a protective device associated with a contactor. Its purpose is to monitor the current flowing in the load (for example of a motor), controlled by the contactor and to cause the opening of the latter in the event of overload, that is to say for a current which can for example, present a value between 1.05 and 1.2 times the nominal cost of the load, the value of which is indicated by the manufacturer.
Ce relais comprend généralement des éléments bimétalliques thermiquement déformables chauffés par le courant qui traverse la charge. A partir d'un certain seuil correspondant à une surcharge, ces éléments actionnent un dispositif de déclenchement qui commande l'ouverture d'un contacteur.This relay generally includes thermally deformable bimetallic elements heated by the current flowing through the load. From a certain threshold corresponding to an overload, these elements actuate a tripping device which controls the opening of a contactor.
Après déclenchement, le réarmement provoquant la remise en service de la charge peut s'effectuer manuellement et/ou automatiquement selon qu'il s'agit d'un relais à réarmement manuel ou d'un relais à réarmement manuel-auto.After tripping, the reset causing the load to be put back into service can be done manually and / or automatically depending on whether it is a manual reset relay or a manual-auto reset relay.
Habituellement, ce dernier type de relais comporte sur l'une des faces du boîtier, sur la face frontale ou sur la face supérieure :
- un bouton de réglage qui permet d'ajuster la protection au courant nominal de la charge contrôlée ;
- un bouton d'arrêt du relais qui agit sur un contact à ouverture ; et
- un bouton à double action, mobile en rotation et en translation axiale qui présente deux positions angulaires, permettant de sélecter le mode de réarmement manuel et le mode de réarmement automatique, et deux positions axiales, à savoir une position normale de repos et une position poussée (avec rappel éventuel sous l'effet d'un ressort) correspondant au réarmement.Usually, this last type of relay comprises on one of the faces of the housing, on the front face or on the upper face:
- an adjustment button which allows the protection to be adjusted to the nominal current of the controlled load;
- a relay stop button which acts on an opening contact; and
- a double action button, movable in rotation and in axial translation which has two angular positions, making it possible to select the manual reset mode and the automatic reset mode, and two axial positions, namely a normal rest position and a position thrust (with possible recall under the effect of a spring) corresponding to rearming.
Il s'avère que dans ce type d'appareils, si l'on ne prend pas suffisamment de précautions et que l'on effectue, lors du réarmement manuel une action provoquant à la fois une pousée et une rotation du bouton à double action, on peut changer malencontreusement le choix initial du mode de réarmement.It turns out that in this type of device, if we do not take enough precautions and we perform, during manual reset an action causing both a push and a rotation of the double action button, the initial choice of rearmament mode can unfortunately be changed.
L'invention a donc plus particulièrement pour but de supprimer ce type d'inconvénients.The invention therefore more particularly aims to eliminate this type of drawback.
A cet effet, elle propose, d'une façon générale, un dispositif d'interdiction sélective apte à équiper un appareil logé dans un boîtier dont l'une des faces comprend au moins un organe de commande manuel à fonctions multiples pouvant passer d'une première position correspondant à une première fonction à une deuxième position correspondant à une deuxiè me fonction et, de l'une au moins de ces deux positions, à une troisième position correspondant à une troisième fonction.To this end, it generally proposes a selective prohibition device capable of equipping a device housed in a housing, one of the faces of which comprises at least one manual control member with multiple functions which can be switched from one first position corresponding to a first function to a second position corresponding to a second me function and, from at least one of these two positions, to a third position corresponding to a third function.
Selon l'invention, ce dispositif est plus particulièrement caractérisé en ce qu'il comprend un capot monté basculant sur ledit boîtier, de manière à pouvoir s'appliquer en position rabattue contre ladite face, ce capot étant conformé de manière à permettre l'accès manuel à l'organe d'actionnement et comprenant des moyens pour autoriser le passage de cet organe d'actionnement des deux premières positions à la troisième position, tout en interdisant son passage de l'une à l'autre de ces deux premières positions.According to the invention, this device is more particularly characterized in that it comprises a cover mounted tilting on said housing, so as to be able to be applied in the folded position against said face, this cover being shaped so as to allow access manual to the actuating member and comprising means for authorizing the passage of this actuating member from the first two positions to the third position, while preventing its passage from one to the other of these first two positions.
Avantageusement, lesdits moyens équipant le capot peuvent consister en des moyens de détrompage coopérant avec des moyens de détrompage correspondants prévus sur l'organe de commande.Advantageously, said means equipping the cover may consist of polarization means cooperating with corresponding polarization means provided on the control member.
Selon un mode d'exécution de l'invention, l'organe d'actionnement consiste en un bouton s'étendant en saillie sur ladite face, ce bouton étant mobile en rotation entre deux positions angulaires et en translation le long de son axe de rotation. Dans ce cas, le capot présente une découpe de forme appropriée pour laisser le passage du bouton, tandis que la forme du bouton est prévue de manière à coopérer avec le bord de ladite découpe pour faire en sorte qu'en position rabattue du capot, le bouton ne puisse pas passer d'une position angulaire à l'autre tout en pouvant être déplacé en translation.According to one embodiment of the invention, the actuating member consists of a button projecting from said face, this button being movable in rotation between two angular positions and in translation along its axis of rotation . In this case, the cover has a cutout of a suitable shape to allow the passage of the button, while the shape of the button is provided so as to cooperate with the edge of said cutout so that in the folded position of the cover, the button cannot pass from one angular position to another while being able to be moved in translation.
A cet effet, ladite découpe et ledit bouton peuvent présenter, l'un, au moins une forme saillante, et l'autre, une forme rentrante adaptée pour recevoir ladite forme saillante dans l'une et/ou l'autre des deux positions angulaires du bouton.To this end, said cutout and said button may have, one, at least one protruding shape, and the other, a re-entrant shape adapted to receive said protruding shape in one and / or the other of the two angular positions. button.
Bien entendu, le capot peut servir à interdire l'accès, par recouvrement, à d'autres organes d'actionnement de l'appareil. Il peut en outre comprendre d'autres évidements autorisant un accès sélectif à une partie seulement des organes d'actionnement de l'appareil.Of course, the cover can be used to prevent access, by overlap, to other actuating members of the device. It may also include other recesses allowing selective access to only part of the actuating members of the device.
Des modes de réalisation de l'invention seront décrits ci-après, à titre d'exemples non limitatifs, avec référence aux dessins annexés dans lesquels :
- La figure 1 est une vue de la face frontale (verticale) d'un relais équipé d'un capot selon l'invention, en position rabattue ;
- La figure 2 est une vue de côté du relais représenté figure 1, capot partiellement ouvert ;
- La figure 3 est une vue de dessus d'un relais dont la face supérieure, portant les organes de manoeuvre et de réglage est équipée d'un capot selon l'invention.
- Figure 1 is a view of the front face (vertical) of a relay equipped with a cover according to the invention, in the folded position;
- Figure 2 is a side view of the relay shown in Figure 1, cover partially open;
- Figure 3 is a top view of a relay whose upper face, carrying the operating and adjusting members is equipped with a cover according to the invention.
Les figures 1 et 2 représentent schématiquement un relais thermique à réarmement "manuel-auto" logé dans un boîtier 1 dont la face frontale verticale 2 est munie d'un bouton de réglage de courant 3, d'un bouton d'arrêt 4 et d'un bouton de sélection/réarmement 5.Figures 1 and 2 schematically represent a thermal relay with "manual-auto" reset housed in a
Comme cela apparaît sur la figure 1, la face antérieure du bouton de réglage de courant 3 s'étend sensiblement dans le plan de la face 2. Ce bouton 3 est mobile en rotation et peut comprendre une fente permettant son actionnement, par exemple à l'aide d'un tournevis.As shown in FIG. 1, the front face of the
Par contre, le bouton d'arrêt 4 qui est mobile en translation, à la façon d'un poussoir, est en saillie par rapport à la face 2.On the other hand, the
Il en est de même en ce qui concerne le bouton de sélection-réarmement 5 qui présente, quant à lui, deux types d'actionnement, à savoir :
- un premier type d'actionnement par rotation permettant son passage d'une position angulaire M correspondant au mode réarmement manuel, à une position angulaire A correspondant au réarmement automatique, et
- un deuxième type d'actionnement, par translation perpendiculairement à la face 2, à la façon d'un poussoir, qui permet d'effectuer le réarmement manuel lorsque le mode réarmement manuel a été sélecté.The same applies to the selection-
a first type of actuation by rotation allowing it to pass from an angular position M corresponding to the manual reset mode, to an angular position A corresponding to the automatic reset, and
- A second type of actuation, by translation perpendicular to the
Par ailleurs, la face verticale 2 du boîtier 1 est munie d'un capot transparent relevable 6, articulé sur le boîtier 1 grâce à des tourillons 7, 8 et qui, en position rabattue, vient recouvrir le bouton de réglage de courant 3 tout en permettant la vue de ce réglage et l'accès au bouton d'arrêt 4.Furthermore, the
Ce capot 6 est en outre muni d'une ouverture 9 pour le passage du bouton de sélection/réarmement 5, ainsi que d'un dispositif de fermeture 10 qui coopère avec un dispositif homologue 11 du boîtier afin de la maintenir en position rabattue et d'un dispositif de plombage, assurant l'inviolabilité de la fermeture.This
Dans cet exemple, le bouton de sélection/réarmement 5, en partie cylindrique, présente une forme de détrompage, en l'occurence, une portion angulaire saillante à 90°, 12, tandis que l'ouverture 9 présente une forme hémicirculaire prolongée par une partie rectangulaire dont les deux angles droits correspondent respectivement aux deux positions angulaires A et M du bouton. La largeur de la partie rectangulaire est égale au diamètre de la forme hémicirculaire et est légèrement supérieure au diamètre du bouton, de sorte qu'il n'est pas possible à ce dernier de passer de l'une à l'autre de ces deux positions angulaires A, M sans soulever le capot 6.In this example, the selection /
De ce fait, la sélection du mode de réarmement auto ou manuel ne peut s'effectuer que capot levé ainsi d'ailleurs que l'affichage du réglage du courant.Therefore, the selection of the auto or manual reset mode can only be carried out with the hood raised as well as the display of the current setting.
Ce détrompage est tel que lorsque le bouton 5 est sélectionné sur M (mode manuel), il est possible d'effectuer une pression sur ce bouton 5 pour obtenir le réarmement sans risquer de provoquer la rotation de celui-ci.This keying is such that when the
Ce dispositif permet donc à l'installateur d'effectuer le réglage du courant et le choix du mode de réarmement lors de la mise en route.This device therefore allows the installer to adjust the current and choose the reset mode during start-up.
Une fois ces choix effectués, la fermeture du capot, avec plombage éventuel, évite toute fausse manoeuvre lors du réarmement et l'intervention abusive d'une personne non autorisée.Once these choices have been made, closing the cover, with possible sealing, avoids any false maneuver during rearming and the improper intervention of an unauthorized person.
Dans l'exemple représenté sur la figure 3, le bouton de réglage du courant 3ʹ, le bouton d'arrêt 4ʹ et le bouton de réarmement 5ʹ sont portés par la face supérieure 13 du boîtier 1.In the example shown in FIG. 3, the current adjustment button 3ʹ, the stop button 4ʹ and the reset button 5ʹ are carried by the
Le bouton de réarmement 5ʹ est identique avec celui représenté sur les figures 1 et 2. Par contre, il ne passe pas au travers du capot 6ʹ mais coopère pour le détrompage avec une découpe 14 formant une région angulaire rentrante à angle droit.The reset button 5ʹ is identical to that shown in FIGS. 1 and 2. On the other hand, it does not pass through the cover 6ʹ but cooperates for the polarization with a
Dans cet exemple, le capot 6ʹ présente une ouverture 15 au travers de laquelle passe le bouton d'arrêt 4ʹ.In this example, the cover 6ʹ has an
Malgré ces légères différences, le mode d'utilisation de ce dispositif demeure le même que celui précédemment décrit.Despite these slight differences, the mode of use of this device remains the same as that previously described.
