L'utilisation d'un module amovible pour la détermination des paramètres de protection long retard est classique dans les déclencheurs électroniques. Certains déclencheurs comportent un circuit de traitement directement connecté à des conducteurs d'un réseau à protéger, de manière à permettre une mesure de tension, par exemple par l'intermédiaire d'un pont diviseur résistif. Cette connexion directe, sans transformateur, doit pouvoir être interrompue, notamment pour la réalisation d'essais d'isolement diélectrique. Dans certains appareils de protection il est prévu un dispositif amovible disposé en face avant qui, lorsqu'il est retiré, interrompt la connexion en tension.The invention relates to an electronic trip device comprising a housing, a circuit electronic processing arranged inside the housing, circuit connection means for processing conductors of a network to be protected, means for determining trigger parameters comprising a removable module, means for fixing the removable module on a front face of the case, the removable module coming into contact, in fixing position, with the treatment circuit. The use of a removable module for the determination of long delay protection parameters is classic in electronic triggers.

The moving part 13 includes flexible contacts 14 (FIGS. 5 and 6) intended to ensure, in the connection position, contact between the first points of contact 8 and the second contact points 9, thus allowing the treatment circuit 4 perform a measurement of the network voltage.

La pièce 13 est normalement repoussée en position de déconnexion par des moyens élastiques, constitués, dans le mode de réalisation préférentiel représenté sur les figures 1, 4, et 7, par un ressort de torsion 15. Le module amovible 3, lorsqu'il est en position de fixation sur la face avant 2 du boítier 1, repousse la pièce mobile 13 en position de connexion, à l'encontre de l'action du ressort de torsion 15. The part 13 is normally pushed back into the disconnected position by means elastic, made up, in the preferred embodiment shown in FIGS. 1, 4, and 7, by a torsion spring 15. The removable module 3, when it is in the position of fixing on the front face 2 of the housing 1, pushes the moving part 13 into position connection, against the action of the torsion spring 15.

Une pièce auxiliaire 16 est de préférence intercalée entre le module amovible 3 et la pièce mobile 13. La pièce auxiliaire 16 (figures 1, 9 et 10) est guidée par une nervure de guidage 17 (figure 1) formée sur une face interne 18 d'une paroi latérale du boítier 1. Elle peut se déplacer le long de la nervure de guidage 17, verticalement sur la figure 1, entre des première et seconde positions. Dans la première position, le module amovible 3, en position de fixation, est en contact, par l'intermédiaire d'au moins une patte latérale 19, avec une extrémité 20 de la pièce auxiliaire 16. La pièce auxiliaire, en contact avec la pièce mobile 13, maintient celle-ci dans sa position de connexion. Lorsque le module amovible 3 n'est pas fixé sur la face avant du déclencheur, il n'exerce pas sur la pièce mobile 13, par l'intermédiaire de la pièce auxiliaire 16, une pression suffisante pour la maintenir en position de connexion. La pièce mobile est alors repoussée en position de déconnexion par le ressort de torsion 15 et repousse la pièce auxiliaire 16 dans sa seconde position, vers le haut sur la figure 1. Le déplacement vers le haut de la pièce auxiliaire 16 est, de préférence, limitée par un ergot de retenue 21 disposé sur la face interne 18. Dans un mode de réalisation préférentiel la pièce 13 est mobile en rotation. Elle comporte deux ergots de rotation 22 (figures 1, 4 et 5) solidaires de flasques latéraux 23 et faisant saillie vers l'extérieur. Les ergots de rotation 22 ont de préférence une extrémité de section rectangulaire destinée à coopérer avec des éléments de guidage 24 (figures 1 et 8) solidaires des faces internes 18 des parois latérales du boítier. Chaque élément de guidage 24 délimite sur l'une des faces 18 un passage rectangulaire 25, étroit, aboutissant dans un espace circulaire 26. La figure 8 représente un ergot de rotation 22 dans deux positions différentes par rapport à l'élément de guidage 24 correspondant. Dans une première position l'ergot, 22a, est prêt à être introduit dans l'élément de guidage. Son orientation est telle qu'il peut être introduit dans le passage rectangulaire 25 dont la largeur 11 est légèrement supérieure à la largueur 12 de la section de l'extrémité de l'ergot et inférieure à la longueur L de cette section. L'espace circulaire 26 a un diamètre légèrement supérieur à la longueur L. Ainsi, lorsque, après être passé dans le passage 25, l'ergot est dans la seconde position (ergot 22b sur la figure 8), à l'intérieur de l'espace circulaire 26, il peut tourner librement.An auxiliary part 16 is preferably interposed between the removable module 3 and the part mobile 13. The auxiliary part 16 (Figures 1, 9 and 10) is guided by a guide rib 17 (Figure 1) formed on an inner face 18 of a side wall of the housing 1. It can be move along the guide rib 17, vertically in FIG. 1, between first and second positions. In the first position, the removable module 3, in position fixing, is in contact, via at least one side tab 19, with a end 20 of the auxiliary part 16. The auxiliary part, in contact with the moving part 13, maintains it in its connection position. When the removable module 3 is not not fixed on the front face of the trigger, it does not exert on the moving part 13, for through the auxiliary part 16, sufficient pressure to keep it in connection position. The moving part is then pushed back into the disconnected position by the torsion spring 15 and pushes the auxiliary part 16 into its second position, towards the top in FIG. 1. The upward movement of the auxiliary part 16 is, from preferably limited by a retaining lug 21 disposed on the internal face 18. In one mode of preferred embodiment the part 13 is movable in rotation. It has two lugs of rotation 22 (Figures 1, 4 and 5) integral with side flanges 23 and projecting towards outside. The rotation pins 22 preferably have a section end rectangular intended to cooperate with guide elements 24 (Figures 1 and 8) integral internal faces 18 of the side walls of the housing. Each guide element 24 delimits on one of the faces 18 a rectangular passage 25, narrow, ending in a space circular 26. Figure 8 shows a rotation lug 22 in two different positions relative to the corresponding guide element 24. In a first position the lug, 22a, is ready to be introduced into the guide element. Its orientation is such that it can be introduced into the rectangular passage 25 whose width 11 is slightly greater than the width 12 of the section of the end of the lug and less than the length L of this section. The circular space 26 has a diameter slightly greater than the length L. Thus, when, after passing through passage 25, the lug is in the second position (lug 22b in FIG. 8), inside the circular space 26, it can rotate freely.

Dans un mode de réalisation particulier (figures 9 et 10), la pièce auxiliaire 16 comporte une partie 27 en saillie, munie sur sa face inférieure d'une nervure 28 dans laquelle peut coulisser le flasque latéral associé de la pièce mobile 13. Lorsque la pièce auxiliaire 16 est dans sa seconde position, haute, repoussée par le ressort de torsion 15, la partie 27 limite la rotation de la pièce 13, de manière à ce que les ergots de rotation 22 ne puissent pas s'échapper des espaces circulaires 26 des éléments de guidage 24 correspondants.In a particular embodiment (Figures 9 and 10), the auxiliary part 16 comprises a projecting part 27, provided on its underside with a rib 28 in which can slide the associated lateral flange of the moving part 13. When the auxiliary part 16 is in its second, high position, pushed back by the torsion spring 15, the part 27 limits the rotation of the part 13, so that the rotation lugs 22 cannot escape from the circular spaces 26 of the corresponding guide elements 24.

Le déclencheur comporte, de préférence, une seule pièce auxiliaire 16, bien que le montage puisse, éventuellement, être symétrique. Pour faciliter le montage de l'ensemble, la pièce mobile 13 peut comporter, sur le flasque 23 opposé à celui qui coopère avec la pièce auxiliaire 16, un ergot de retenue 29 (figures 4 et 5) susceptible de coopérer avec une nervure 30 de la face interne de la paroi associée du boítier (figure 3). L'ergot de retenue 29 permet ainsi de maintenir la pièce mobile 13 à l'intérieur du boítier 1, même en l'absence de la pièce auxiliaire 16, par exemple avant le montage de celle-ci. Les dimensions respectives des divers composants, une certaine élasticité des flasques 23 ainsi que de la pièce auxiliaire 16, en matière thermoplastique, ainsi que la section croissante de l'ergot de retenue 21, permettent la mise en place et, éventuellement le démontage, de la pièce mobile 13 et de la pièce auxiliaire 16 malgré la présence des ergots de retenue 29 et 21.The trigger preferably comprises a single auxiliary part 16, although the mounting could possibly be symmetrical. To facilitate assembly of the assembly, the part mobile 13 may comprise, on the flange 23 opposite to that which cooperates with the part auxiliary 16, a retaining lug 29 (Figures 4 and 5) capable of cooperating with a rib 30 of the internal face of the associated wall of the housing (Figure 3). The retaining lug 29 thus keeps the moving part 13 inside the housing 1, even in the absence of the auxiliary part 16, for example before the assembly thereof. The respective dimensions of the various components, a certain elasticity of the flanges 23 as well that of the auxiliary part 16, of thermoplastic material, as well as the increasing section of the retaining lug 21, allow the establishment and, possibly disassembly, of the moving part 13 and the auxiliary part 16 despite the presence of the retaining pins 29 and 21.

Le ressort de torsion 15 comporte une partie centrale et deux extrémités. Une première extrémité, libre, est destinée à prendre appui sur une rainure 31 disposée dans le fond du boítier 1 (figure 3). La partie centrale du ressort de torsion est montée sur un ergot 32, disposé dans le prolongement de l'un des ergots de rotation 22, c'est-à-dire en saillie vers l'intérieur par rapport au flasque latéral 23 correspondant de la pièce mobile 13. (figures 4 et 5). Le ressort de torsion est prépositionné sur la pièce mobile par des éléments de retenue appropriés.The torsion spring 15 has a central part and two ends. A first end, free, is intended to bear on a groove 31 disposed in the bottom of the housing 1 (Figure 3). The central part of the torsion spring is mounted on a lug 32, arranged in the extension of one of the rotation pins 22, that is to say projecting towards the interior with respect to the corresponding lateral flange 23 of the movable part 13. (figures 4 and 5). The torsion spring is prepositioned on the moving part by elements of appropriate restraint.

Dans le mode particulier de réalisation représenté à la figure 5, la pièce mobile 13 porte 4 contacts souples 14 identiques, destinés à être associés à chacun des conducteurs de phase et au conducteur de neutre d'un réseau 11 triphasé avec neutre. Les contacts 14 sont montés sur la pièce mobile 13 soit par thermosoudure, soit par clipsage. Ils sont disposés à la partie inférieure de la pièce 13 dans des emplacements délimités par des parois latérales de protection 33. Chaque contact 14 comporte une zone de fixation 34 et se termine par deux zones de contact séparées 35, souples, destinées respectivement à venir en contact avec les points de contact 8 et 9. Pour améliorer le contact, chaque zone de contact comporte, de préférence, à sa partie inférieure, un léger renflement 36, qui peut être obtenu par emboutissage. Les figures 15 et 16 représentent, en coupe, les positions respectives du module amovible 3, de la pièce auxiliaire 16, de la pièce mobile 13 et de ses contacts 14, ainsi que de la plaque de circuit imprimé 5b. En position de fixation du module amovible 3 (fig.15), les contacts 14 sont en contact avec la plaque 5b de circuit imprimé qui est disposée entre le fond du boítier et la pièce mobile 13. En position déverrouillée du module amovible 3 (figure 16), le ressort de torsion 15 repousse la pièce mobile 13 et ses contacts 14 en position de déconnexion.In the particular embodiment shown in Figure 5, the movable part 13 carries 4 identical flexible contacts 14, intended to be associated with each of the phase conductors and to the neutral conductor of a three-phase network 11 with neutral. Contacts 14 are mounted on the moving part 13 either by heat sealing or by clipping. They are willing to part bottom of the part 13 in locations delimited by side walls of protection 33. Each contact 14 has a fixing zone 34 and ends in two separate, flexible contact zones 35, intended respectively to come into contact with the contact points 8 and 9. To improve contact, each contact zone includes, preferably, at its lower part, a slight bulge 36, which can be obtained by stamping. Figures 15 and 16 show, in section, the respective positions of the removable module 3, of the auxiliary part 16, of the movable part 13 and of its contacts 14, as well as the printed circuit board 5b. In the removable module fixing position 3 (fig.15), the contacts 14 are in contact with the printed circuit board 5b which is disposed between the bottom of the housing and the moving part 13. In the unlocked position of the module removable 3 (Figure 16), the torsion spring 15 pushes the moving part 13 and its contacts 14 in the disconnection position.

Un mode particulier de réalisation du module amovible 3 est représenté aux figures 11 à 14. Ses pattes latérales 19 comportent à leurs extrémités libres des crochets de retenue 37 qui permettent de le maintenir solidaire de la face avant 2 du boítier en position déverrouillée. Les pattes latérales 19, disposées par paires de part et d'autre du module 3, traversent des orifices 38 correspondants de la face avant 2 (figure 1). Elles possèdent une certaine élasticité, ce qui permet, en rapprochant les deux pattes latérales de chaque paire, de les introduire dans l'orifice 38 correspondant. Une fois le module amovible 3 mis en place, il est fixé sur la face avant au moyen d'une vis 39 (figure 12) qui se visse dans un orifice fileté 40 complémentaire formé dans la face avant du déclencheur (fig. 1). La vis 39 est de préférence du type imperdable, solidaire du module amovible 3 en translation selon l'axe de la vis. De cette manière, le dévissage de la vis, à travers un orifice 41 formé dans la face externe du module amovible 3, entraíne automatiquement le soulèvement du module amovible 3 par rapport à la face avant 2 du déclencheur, son déverrouillage et, en conséquence, le passage en position de déconnexion de la pièce mobile 13.A particular embodiment of the removable module 3 is shown in Figures 11 to 14. Its lateral tabs 19 have at their free ends retaining hooks 37 which keep it integral with the front face 2 of the housing in position unlocked. The lateral tabs 19, arranged in pairs on either side of the module 3, pass through corresponding holes 38 of the front face 2 (FIG. 1). They have a certain elasticity, which allows, by bringing the two side tabs of each pair, introduce them into the corresponding orifice 38. Once the removable module 3 is put in place, it is fixed on the front face by means of a screw 39 (figure 12) which is screwed in a complementary threaded orifice 40 formed in the front face of the release (fig. 1). The opinion 39 is preferably of the captive type, integral with the removable module 3 in translation along the axis of the screw. In this way, the unscrewing of the screw, through an orifice 41 formed in the outer face of the removable module 3, automatically causes the lifting of the removable module 3 with respect to the front face 2 of the release, its unlocking and, in Consequently, moving into the disconnected position of the moving part 13.

La face externe du module amovible comporte, de manière classique, des orifices 42 pour le passage de commutateurs ou de potentiomètres de réglage. Ces orifices 42 sont alignés avec des orifices 43 de la face avant du déclencheur. Les commutateurs ou potentiomètres de réglage, faisant partie du circuit de traitement , sont portés par le circuit imprimé 5. L'élasticité des pattes 19 permet également une extraction complète du module amovible 3, malgré les crochets de retenue 37.The external face of the removable module comprises, in a conventional manner, orifices 42 for the passage of switches or adjustment potentiometers. These holes 42 are aligned with orifices 43 on the front face of the trigger. Switches or potentiometers adjustment, part of the processing circuit, are carried by the printed circuit 5. The elasticity of the tabs 19 also allows complete extraction of the removable module 3, despite the retaining hooks 37.

Le module amovible 3 comporte un circuit imprimé 43, représenté de profil à la figure 13. Le circuit imprimé 43, portant les contacts 6 du module amovible, est disposé à l'intérieur d'un logement approprié 44 prévu dans la partie inférieure du module amovible. Le circuit imprimé 43 est maintenu en place dans le logement 44 par un couvercle 45 (figure 14) qui se clipse dans le logement. Le couvercle 45 comporte des orifices 46 pour le passage des contacts 66. Par ailleurs, le couvercle 45 porte un guide de lumière 47. Lorsque le module amovible 3 est en position de fixation, une extrémité du guide de lumière vient en contact avec une diode électroluminescente d'alarme (LED 49, fig. 2) du circuit de traitement 4, montée sur le circuit imprimé 5. La diode d'alarme 49 s'allume, par exemple, lorsque le seuil de déclenchement long retard est atteint. L'information lumineuse correspondante est transmise directement par le guide de lumière 47 jusqu'à un orifice 48 correspondant formé sur la face externe du module amovible (fig. 11), constituant ainsi un voyant lumineux.The removable module 3 comprises a printed circuit 43, shown in profile in FIG. 13. The printed circuit 43, carrying the contacts 6 of the removable module, is arranged inside an appropriate housing 44 provided in the lower part of the removable module. The circuit printed 43 is held in place in the housing 44 by a cover 45 (Figure 14) which clips into the housing. The cover 45 has orifices 46 for the passage of contacts 66. Furthermore, the cover 45 carries a light guide 47. When the module removable 3 is in the fixing position, one end of the light guide comes into contact with an alarm light-emitting diode (LED 49, fig. 2) of the processing circuit 4, mounted on the printed circuit 5. The alarm diode 49 lights up, for example, when the long delay trip threshold is reached. The corresponding light information is transmitted directly by the light guide 47 to a corresponding orifice 48 formed on the external face of the removable module (fig. 11), thus constituting an indicator light.

La figure 2 schématise les connexions électriques entre le circuit imprimé 5 et le circuit imprimé 43 du module amovible 3. Dans le mode de réalisation particulier représenté à la figure 2, le circuit imprimé 43 est connecté à cinq bornes 7 du circuit de traitement 4, par des contacts 6. Une première borne 7 est connectée à un point commun à quatre conducteurs formés sur le circuit imprimé et connectés respectivement aux quatre autres bornes 7. Chacun des conducteurs peut être interrompu, le nombre et la disposition des conducteurs intègres correspondant à un codage, sur 4 bits, de la valeur du paramètre long retard associé au module choisi.Figure 2 shows schematically the electrical connections between the printed circuit 5 and the circuit printed 43 of the removable module 3. In the particular embodiment shown in FIG. 2, the printed circuit 43 is connected to five terminals 7 of the processing circuit 4, by contacts 6. A first terminal 7 is connected to a point common to four conductors formed on the printed circuit and respectively connected to the other four terminals 7. Each of the conductors can be interrupted, the number and arrangement of integral conductors corresponding to a 4-bit coding of the value of the long parameter delay associated with the chosen module.

A titre de variante, la pièce 13 peut être remplacée par une pièce 13a mobile en translation dans le boítier (figure 17). La pièce auxiliaire est alors constituée par une pièce 16a, solidaire de la pièce mobile 13a. Dans le mode particulier de réalisation représenté à la figure 17, les moyens élastiques destinés à repousser le module amovible 13a en position de déconnexion sont constitués par un ressort 50, guidé dans des éléments appropriés du boítier, et prenant appui d'une part sur le fond du boítier 1 et, d'autre part, sur un rebord de la pièce auxiliaire 16a. En position de fixation du module amovible 3 sur la face avant du déclencheur, celui repousse la pièce auxiliaire 16a, et la pièce mobile 13a, vers le fond du boítier, à l'encontre de l'action du ressort 50 qui est alors comprimé. Les contacts 14 viennent alors en contact avec le circuit imprimé 5b. Par contre, dès que le module amovible 3 est en position déverrouillée, comme représenté à la figure 17, le ressort 50 repousse la pièce intermédiaire 16a vers le haut, celle-ci entraínant la pièce mobile 13a, et interrompant le contact entre les contacts 14 et le circuit imprimé 5b.Alternatively, the part 13 can be replaced by a part 13a movable in translation in the housing (Figure 17). The auxiliary part is then constituted by a part 16a, secured to the moving part 13a. In the particular embodiment shown in FIG. 17, the elastic means intended to push the removable module 13a into the position of disconnection are constituted by a spring 50, guided in appropriate elements of the case, and bearing on the one hand on the bottom of the case 1 and, on the other hand, on a flange of the auxiliary part 16a. In the fixing position of the removable module 3 on the front face of the trigger, that pushes the auxiliary part 16a, and the moving part 13a, towards the bottom of the housing, against the action of the spring 50 which is then compressed. Contacts 14 then come into contact with the printed circuit 5b. However, as soon as the module removable 3 is in the unlocked position, as shown in Figure 17, the spring 50 pushes the intermediate part 16a upwards, the latter driving the moving part 13a, and interrupting the contact between the contacts 14 and the printed circuit 5b.

Dans tous les cas, le déverrouillage du module amovible 3 s'accompagne de la déconnexion automatique des entrées de tension du circuit de traitement. L'interruption de la connexion en tension, notamment pour la réalisation d'essais diélectriques, est réalisée simplement, par déverrouillage du module amovible 3, sans risque que l'utilisateur accède aux conducteurs sous tension (220 V) depuis la face avant, contrairement à ce qui se passait dans les dispositifs connus. L'ensemble selon l'invention regroupe ainsi avantageusement deux fonctions, à savoir le calibrage du long retard et la déconnexion de la mesure de tension.In all cases, unlocking the removable module 3 is accompanied by disconnection automatic processing circuit voltage inputs. Connection interruption in voltage, in particular for carrying out dielectric tests, is carried out simply, by unlocking the removable module 3, without risk of the user accessing the live conductors (220 V) from the front panel, unlike what was happening in known devices. The assembly according to the invention thus advantageously groups together two functions, namely the calibration of the long delay and the disconnection of the measurement of voltage.

Dans le mode de réalisation représenté à la figure 1, le circuit imprimé 5 est constitué de 3 parties et, en position de déconnexion, la tension du réseau n'est présente qu'à l'entrée inférieure du connecteur 10, sur les points de contacts 8 et dans les conducteurs de la plaque du circuit imprimé 5c faisant la liaison entre le connecteur 10 et les points de contacts 8. Tous ces emplacements sont éloignés de la face avant 2 du disjoncteur et, de plus, leur accès est protégé par la présence de la face avant et, si celle-ci est retirée, par le fait que les conducteurs de liaison entre le connecteur 10 et les points de contacts 8 sont, de préférence, formés sur la face de la plaque de circuit imprimé 5c disposé vers l'intérieur, entre les plaques de circuit imprimé 5a et 5b. In the embodiment shown in FIG. 1, the printed circuit 5 consists of 3 parts and, in the disconnected position, the mains voltage is only present at the input connector 10, on the contact points 8 and in the conductors of the printed circuit board 5c making the connection between the connector 10 and the points of contacts 8. All of these locations are distant from the front face 2 of the circuit breaker and, from more, their access is protected by the presence of the front panel and, if this is removed, by the fact that the connecting conductors between the connector 10 and the contact points 8 are, preferably formed on the face of the printed circuit board 5c disposed inwards, between the printed circuit boards 5a and 5b.

Selon une variante de réalisation, une plaque de circuit imprimé additionnelle peut être disposée entre la face avant 2 et la plaque de circuit imprimé 5a. Ceci limite d'autant plus les risques d'accès aux pièces sous tension. Dans ce cas les points de contacts 7, la diode électroluminescente 49, les potentiomètres ou commutateurs de réglage, sont situés sur la plaque de circuit imprimé additionnelle, ou un passage adapté est prévu dans celle-ci.According to an alternative embodiment, an additional printed circuit board can be disposed between the front face 2 and the printed circuit board 5a. This limits all the more the risk of access to live parts. In this case the contact points 7, the diode 49, the potentiometers or adjustment switches, are located on the additional printed circuit board, or a suitable passage is provided therein.
