Description

L'invention concerne, de façon générale, le domaine des appareillages électriques.The invention relates generally to the field of electrical equipment.

Plus précisément, l'invention concerne un dispositif de coupure de courant électrique, tel qu'un interrupteur sectionneur, comprenant :

  • un boîtier;
  • au moins un contact fixe solidaire du boîtier;
  • un chariot monté coulissant dans le boîtier suivant une direction axiale entre une position inactive et une position finale d'enclenchement en passant par une position de retenue;
  • un contact mobile monté à coulissement dans le chariot suivant la direction axiale, en appui sur une butée du chariot dans les positions inactive et de retenue du chariot, et appliqué sur chaque contact fixe dans la position finale d'enclenchement du chariot;
  • un premier ressort logé dans le chariot, précontraint en compression, et présentant une première extrémité exerçant sur le contact mobile, suivant la direction axiale, une force élastique dirigée vers le contact fixe;
  • des moyens d'actionnement comprenant un excentrique et une biellette dont une première extrémité est liée à l'excentrique, ces moyens d'actionnement étant manoeuvrables à l'extérieur du boîtier depuis une position de repos vers une position finale d'enclenchement en passant par une position d'engagement et une position d'échappement, et étant conçus pour exercer sélectivement, suivant la direction axiale, sur une deuxième extrémité du premier ressort, et par l'intermédiaire d'une deuxième extrémité de la biellette, une force dirigée vers le contact fixe dans un sens propre à augmenter la compression du premier ressort;
  • et des moyens de retenue comprenant un organe de retenue lié au boîtier et conçus pour maintenir le chariot dans sa position de retenue pour toute position des moyens d'actionnement comprise entre leur position d'engagement et leur position d'échappement, et pour libérer le chariot au franchissement, par les moyens d'actionnement, de leur position d'échappement, le chariot étant alors brusquement déplacé vers sa position finale d'enclenchement par détente partielle du premier ressort.
More specifically, the invention relates to an electric current cut-off device, such as a disconnect switch, comprising:
  • a housing;
  • at least one fixed contact secured to the housing;
  • a carriage slidably mounted in the housing in an axial direction between an inactive position and a final latching position through a retaining position;
  • a movable contact slidably mounted in the carriage in the axial direction, resting on a stop of the carriage in the inactive and retaining positions of the carriage, and applied to each fixed contact in the final position of engagement of the carriage;
  • a first spring housed in the carriage, prestressed in compression, and having a first end exerting on the movable contact, in the axial direction, an elastic force directed towards the fixed contact;
  • actuating means comprising an eccentric and a rod whose first end is connected to the eccentric, these actuating means being operable outside the housing from a rest position to a final latching position through an engagement position and an exhaust position, and being designed to exercise selectively, following the direction axial, on a second end of the first spring, and through a second end of the rod, a force directed towards the fixed contact in a direction to increase the compression of the first spring;
  • and retaining means comprising a retainer connected to the housing and adapted to hold the carriage in its retaining position for any position of the actuating means between their engaged position and their exhaust position, and to release the carriage to the crossing, by the actuating means, their exhaust position, the carriage is then abruptly moved to its final position of engagement by partial expansion of the first spring.

Un dispositif de ce type est par exemple décrit dans le brevet américain US 7 115 829 .A device of this type is for example described in the US patent US 7,115,829 .

Dans ce type de dispositif, la réalisation des moyens de retenue est soumise à deux contraintes antinomiques que représentent d'une part la nécessité de doter ce dispositif d'un fonctionnement fiable et reproductible, et d'autre part le souhait d'obtenir cette qualité de fonctionnement avec une structure aussi simple que possible.In this type of device, the realization of the retaining means is subject to two antinomic constraints which represent on the one hand the need to provide this device with a reliable and reproducible operation, and on the other hand the desire to obtain this quality. operating with a structure as simple as possible.

Dans ce contexte, la présente invention a pour but de proposer un dispositif de coupure de courant électrique, tel qu'un interrupteur sectionneur, dont les moyens de retenue répondent de manière très satisfaisante à ce besoin.In this context, the purpose of the present invention is to propose an electric current cut-off device, such as a disconnect switch, whose retaining means respond very satisfactorily to this need.

A cette fin, le dispositif de coupure de l'invention, par ailleurs conforme à la définition générique qu'en donne le préambule ci-dessus, est essentiellement caractérisé en ce que l'organe de retenue lié au boîtier est constitué par un épaulement du boîtier, en ce que les moyens de retenue comprennent en outre un cliquet monté pivotant sur le chariot autour d'un axe de pivotement, en ce que ce cliquet comporte au moins une première came s'étendant obliquement par rapport à la direction axiale et une surface d'appui coopérant avec ledit épaulement pour maintenir le chariot dans sa position de retenue, en ce que la deuxième extrémité de la biellette coopère avec la première came pour provoquer, au passage des moyens d'actionnement de leur position d'engagement à leur position d'échappement, un pivotement correspondant du cliquet dans un premier sens autour de son axe de pivotement, et en ce que ladite surface d'appui du cliquet échappe à l'épaulement du boîtier au franchissement, par les moyens d'actionnement, de leur position d'échappement.For this purpose, the breaking device of the invention, moreover in conformity with the generic definition given in the preamble above, is essentially characterized in that the retaining member connected to the housing is constituted by a shoulder of the housing, in that the retaining means further comprises a pawl pivotally mounted on the carriage about a pivot axis, in that this ratchet comprises at least a first cam extending obliquely with respect to the axial direction and a bearing surface cooperating with said shoulder to hold the carriage in its retaining position, in that the second end of the link cooperates with the first cam to cause, as the actuating means move from their engagement position to their exhaust position, a corresponding pivoting of the pawl in a first direction about its pivot axis, and in that said ratchet bearing surface escapes the shoulder of the housing crossing, by the actuating means, their exhaust position.

De façon connue en soi, le premier ressort peut être constitué par un ressort hélicoïdal.In known manner, the first spring may be constituted by a helical spring.

De préférence, la deuxième extrémité de la biellette s'étend transversalement à la direction axiale et appuie directement sur la deuxième extrémité du premier ressort.Preferably, the second end of the rod extends transversely to the axial direction and bears directly on the second end of the first spring.

Par ailleurs, l'épaulement peut venir de matière avec la paroi de fond dont est traditionnellement doté le boîtier.In addition, the shoulder may be integral with the bottom wall which is traditionally provided with the housing.

Dans ce cas notamment, le chariot peut présenter une face postérieure qui est disposée en regard de la paroi de fond du boîtier, et sur laquelle le cliquet est monté pivotant.In this particular case, the carriage may have a rear face which is disposed facing the bottom wall of the housing, and on which the pawl is pivotally mounted.

Il est alors judicieux de prévoir que la face postérieure du chariot présente une fente parallèle à la direction axiale, que la deuxième extrémité de la biellette traverse cette fente, et que cette fente soit conçue, au moins par ses dimensions, pour pouvoir guider la deuxième extrémité de la biellette suivant la direction axiale.It is therefore advisable to provide that the rear face of the carriage has a slot parallel to the axial direction, the second end of the link passes through this slot, and that this slot is designed, at least by its dimensions, to be able to guide the second end of the link in the axial direction.

Le chariot peut aussi présenter une face antérieure disposée parallèlement et à distance de sa face postérieure, et cette face antérieure peut être également traversée par la deuxième extrémité de la biellette.The carriage may also have an anterior face disposed parallel to and at a distance from its posterior face, and this anterior face may also be traversed by the second end of the link.

Dans le mode de réalisation préféré de l'invention, il est prévu que la première came du cliquet soit disposée entre l'axe de pivotement et la surface d'appui de ce cliquet, que ce cliquet comprenne une deuxième came s'étendant sensiblement parallèlement à la première came et disposée entre ladite première came et l'axe de pivotement du cliquet, et que la deuxième extrémité de la biellette coopère avec la deuxième came pour provoquer, au passage du chariot de sa position finale d'enclenchement à sa position inactive, un pivotement correspondant du cliquet dans un deuxième sens autour de son axe de pivotement, replaçant la surface d'appui du cliquet en position latente d'engagement avec l'épaulement du boîtier.In the preferred embodiment of the invention, it is provided that the first cam of the pawl is disposed between the pivot axis and the bearing surface of this pawl, that this pawle comprises a second cam extending substantially parallel. to the first cam and disposed between said first cam and the pivoting axis of the pawl, and that the second end of the link cooperates with the second cam to cause, as the carriage passes from its final latching position to its inactive position , a corresponding pivoting of the pawl in a second direction about its pivot axis, replacing the pawl bearing surface latent position of engagement with the shoulder of the housing.

Le cliquet présente par exemple une lumière délimitée par un bord fermé et disposée entre l'axe de pivotement et la surface d'appui de ce cliquet, chaque came du cliquet pouvant alors être définie par une portion du bord de ladite lumière.The pawl has for example a light delimited by a closed edge and disposed between the pivot axis and the bearing surface of the pawl, each cam of the pawl can then be defined by a portion of the edge of said light.

De façon connue en soi, ce dispositif de coupure de courant électrique peut aussi comporter un deuxième ressort précontraint en compression entre le boîtier et le chariot, ce deuxième ressort sollicitant en permanence le chariot vers sa position inactive.In a manner known per se, this electric current cut-off device can also include a second spring prestressed in compression between the housing and the carriage, this second spring constantly urging the carriage to its inactive position.

Le chariot 3 est monté coulissant dans le boîtier 1, suivant une direction axiale Z représentée verticalement sur les figures 2 à 14, entre une position inactive visible aux figures 5 et 6 et une position finale d'enclenchement visible aux figures 13 et 14, en passant par une position de retenue visible aux figures 7 à 10.The carriage 3 is slidably mounted in the housing 1, in an axial direction Z shown vertically on the Figures 2 to 14 , between an inactive position visible to Figures 5 and 6 and a final latching position visible to Figures 13 and 14 , passing through a restraint position visible to Figures 7 to 10 .

Accessoirement, un tel dispositif comprend généralement aussi un deuxième ressort 42 précontraint en compression entre le boîtier 1 et le chariot 3, ce deuxième ressort 42 étant par exemple constitué par un ressort hélicoïdal et sollicitant en permanence le chariot 3 vers sa position inactive.Incidentally, such a device generally also comprises a second spring 42 prestressed in compression between the housing 1 and the carriage 3, this second spring 42 being for example constituted by a helical spring and continuously urging the carriage 3 to its inactive position.

Le contact mobile 22 est monté à coulissement dans le chariot 3 suivant la direction axiale Z.The movable contact 22 is slidably mounted in the carriage 3 in the axial direction Z.

Ce contact mobile 22, qui est en appui sur une butée 30 du chariot 3 dans la position inactive (figures 5 et 6) et dans la position de retenue (figures 7 à 10) de ce chariot 3, est en revanche appliqué sur chaque contact fixe 22 dans la position finale d'enclenchement du chariot 3 (figures 13 et 14).This movable contact 22, which bears on an abutment 30 of the carriage 3 in the inactive position ( Figures 5 and 6 ) and in the retaining position ( Figures 7 to 10 ) of this carriage 3, is however applied to each fixed contact 22 in the final position of engagement of the carriage 3 ( Figures 13 and 14 ).

Le ressort 41, qui est de préférence lui aussi constitué par un ressort hélicoïdal, est logé dans le chariot 3 et précontraint en compression.The spring 41, which is also preferably constituted by a helical spring, is housed in the carriage 3 and prestressed in compression.

L'extrémité 411 du ressort 41, c'est-à-dire l'extrémité inférieure de ce ressort sur les figures, exerce ainsi, sur le contact mobile 22 et suivant la direction axiale Z, une force élastique dirigée vers le contact fixe 21, c'est-à-dire vers le bas sur les figures 2 à 14. Cette force élastique est donc antagoniste à celle exercée par le ressort 42, mais de valeur supérieure.The end 411 of the spring 41, that is to say the lower end of this spring in the figures, thus exerts, on the movable contact 22 and in the axial direction Z, an elastic force directed towards the fixed contact 21 , that is, down on the Figures 2 to 14 . This elastic force is therefore antagonistic to that exerted by the spring 42, but of higher value.

Les moyens d'actionnement 5, qui comprennent un excentrique 51 et une biellette 52, ont pour fonction de permettre d'augmenter la compression du ressort 41 pour pouvoir déplacer le chariot 3 de sa position inactive vers sa position finale d'enclenchement à l'encontre de la force de rappel antagoniste exercée sur le chariot 3 par le deuxième ressort 42.The actuating means 5, which comprise an eccentric 51 and a rod 52, have the function of making it possible to increase the compression of the spring 41 in order to be able to move the carriage 3 from its inactive position to its final engagement position with the against the antagonistic restoring force exerted on the carriage 3 by the second spring 42.

Pour ce faire, l'excentrique 51, qui est monté à rotation dans le boîtier 1 autour de son moyeu 510, présente une manette 511 permettant de le manoeuvrer depuis l'extérieur du boîtier 1.To do this, the eccentric 51, which is rotatably mounted in the housing 1 around its hub 510, has a handle 511 for operating from outside the housing 1.

Par ailleurs, la biellette 52 présente une extrémité 521 cinématiquement liée à l'excentrique 51 et une extrémité 522 agissant sur l'extrémité 412 du ressort 41, c'est-à-dire sur l'extrémité supérieure de ce ressort 41 dans la disposition illustrée aux figures 2 à 14.Moreover, the rod 52 has an end 521 kinematically connected to the eccentric 51 and an end 522 acting on the end 412 of the spring 41, that is to say on the upper end of this spring 41 in the arrangement illustrated in Figures 2 to 14 .

Une action sur la manette 511, exercée à l'extérieur du boîtier 1, permet donc de provoquer une rotation de l'excentrique 51 autour de son moyeu 510 et un coulissement de la biellette 52.An action on the handle 511, exerted outside the casing 1, thus makes it possible to cause a rotation of the eccentric 51 around its hub 510 and a sliding of the rod 52.

Plus précisément, l'excentrique 51 et la biellette 52 peuvent ainsi être simultanément déplacés depuis une position de repos visible aux figures 5 et 6, vers une position finale d'enclenchement visible aux figures 13 et 14, en passant notamment par une position d'engagement visible aux figures 7 et 8, et par une position d'échappement visible aux figures 11 et 12.More specifically, the eccentric 51 and the rod 52 can thus be simultaneously moved from a visible rest position to Figures 5 and 6 , towards a final latching position visible to Figures 13 and 14 , including through a visible engagement position to the Figures 7 and 8 , and by an escape position visible to Figures 11 and 12 .

Lors de ce mouvement, les moyens d'actionnement 5 exercent, sur l'extrémité 412 du ressort 41, par l'intermédiaire de l'extrémité 522 de la biellette 52, et suivant la direction axiale Z, une force qui est dirigée vers le contact fixe 21, c'est-à-dire vers le bas sur les figures 2 à 14, et qui a pour effet d'augmenter la compression du ressort 41 à partir de la position d'engagement de ces moyens d'actionnement, illustrée aux figures 7 et 8.During this movement, the actuating means 5 exert, on the end 412 of the spring 41, via the end 522 of the rod 52, and in the axial direction Z, a force which is directed towards the fixed contact 21, that is to say down on the Figures 2 to 14 , and which has the effect of increasing the compression of the spring 41 from the engagement position of these actuating means, illustrated in FIGS. Figures 7 and 8 .

Les moyens de retenue 6, qui comprennent un organe de retenue 61 lié au boîtier 1, sont conçus pour maintenir le chariot 3 dans sa position de retenue (figures 7 à 10) pour toute position des moyens d'actionnement 5 comprise entre leur position d'engagement (figures 7 et 8) et leur position d'échappement (figures 11 et 12), et pour libérer le chariot 3 au franchissement, par les moyens d'actionnement 5, de leur position d'échappement (figures 11 et 12).The retaining means 6, which comprise a retaining member 61 connected to the casing 1, are designed to keep the carriage 3 in its retaining position ( Figures 7 to 10 ) for any position of the actuating means 5 between their engagement position ( Figures 7 and 8 ) and their exhaust position ( Figures 11 and 12 ), and to release the carriage 3 at the crossing, by the actuating means 5, from their exhaust position ( Figures 11 and 12 ).

Lors du franchissement, par les moyens d'actionnement 5, de leur position d'échappement, le chariot 3 est brusquement déplacé vers sa position finale d'enclenchement par détente partielle du ressort 41, préalablement précontraint de façon importante par ces moyens d'actionnement 5.During the crossing, by the actuating means 5, of their exhaust position, the carriage 3 is abruptly moved towards its final position of engagement by partial expansion of the spring 41, previously significantly prestressed by these actuating means 5.

Dans ce contexte, l'apport de l'invention concerne principalement la simplification des moyens de retenue 6.In this context, the contribution of the invention mainly concerns the simplification of the retaining means 6.

Selon l'invention, l'organe de retenue lié au boîtier 1 est constitué par un épaulement 61 du boîtier, et ces moyens de retenue 6 comprennent en outre un cliquet 62 monté pivotant sur le chariot 3 autour d'un axe de pivotement X, de préférence transversal à la direction axiale Z.According to the invention, the retaining member connected to the housing 1 is constituted by a shoulder 61 of the housing, and these retaining means 6 further comprise a pawl 62 pivotally mounted on the carriage 3 about a pivot axis X, preferably transverse to the axial direction Z.

Le cliquet 62 comporte (figure 3) une came 621 qui s'étend obliquement par rapport à la direction axiale Z, et une surface d'appui 623 qui coopère avec l'épaulement 61 pour maintenir le chariot 3 dans sa position de retenue.The ratchet 62 has ( figure 3 ) a cam 621 which extends obliquely with respect to the axial direction Z, and a bearing surface 623 which cooperates with the shoulder 61 to maintain the carriage 3 in its retaining position.

Entre la position de repos (figures 5 et 6) et la position d'engagement (figures 7 et 8) des moyens d'actionnement 5, le ressort 42 est progressivement comprimé et la surface d'appui 623 du cliquet 62 se rapproche de l'épaulement 61 jusqu'à venir en contact avec lui dans la position d'engagement de ces moyens d'actionnement 5.Between the rest position ( Figures 5 and 6 ) and the commitment position ( Figures 7 and 8 ) actuating means 5, the spring 42 is gradually compressed and the bearing surface 623 of the pawl 62 approaches the shoulder 61 to come into contact with it in the engagement position of these means of actuation 5.

Ensuite, l'appui de la surface d'appui 623 sur l'épaulement 61 permet de maintenir le chariot 3 dans sa position de retenue pendant que les moyens d'actionnement 5, ayant dépassé leur position d'engagement, poursuivent leur mouvement vers leur position d'échappement, comme le montrent les figures 9 et 10, et compriment progressivement le ressort 41.Then, the support of the bearing surface 623 on the shoulder 61 keeps the carriage 3 in its retaining position while the actuating means 5, having exceeded their engagement position, continue their movement towards their position. exhaust position, as shown by the Figures 9 and 10 , and gradually compress the spring 41.

Par ailleurs, l'extrémité 522 de la biellette 52 coopère avec la came 621 pour provoquer, au cours du passage des moyens d'actionnement 5 de leur position d'engagement à leur position d'échappement, un pivotement correspondant du cliquet 62 dans le sens d'un dégagement D autour de son axe de pivotement X (figure 10).Furthermore, the end 522 of the rod 52 cooperates with the cam 621 to cause, during the passage of the actuating means 5 from their engagement position to their exhaust position, a corresponding pivoting of the pawl 62 in the direction of a clearance D about its pivot axis X ( figure 10 ).

Ce pivotement est dimensionné de manière que, lorsque les moyens d'actionnement 5 franchissent leur position d'échappement (figure 12), la surface d'appui 623 du cliquet 62 échappe à l'épaulement 61 du boîtier 1, permettant ainsi au ressort 41 de déplacer brusquement le chariot 3 vers sa position finale d'enclenchement.This pivoting is dimensioned so that, when the actuating means 5 pass through their exhaust position ( figure 12 ), the bearing surface 623 of the pawl 62 escapes the shoulder 61 of the housing 1, thus allowing the spring 41 to suddenly move the carriage 3 to its final latching position.

En fait, comme le montrent les figures 8, 10 et 12, la came 621 peut être conformée de manière que l'extrémité 522 de la biellette 52 ne provoque le pivotement du cliquet 62 qu'à partir de la position intermédiaire illustrée à la figure 10, c'est-à-dire seulement au voisinage de la fin du passage des moyens d'actionnement 5 de leur position d'engagement vers leur position d'échappement.In fact, as shown by figures 8 , 10 and 12 , the cam 621 may be shaped so that the end 522 of the rod 52 causes the pawl 62 to pivot only from the intermediate position illustrated in FIG. figure 10 , that is to say only in the vicinity of the end of the passage of the actuating means 5 from their engagement position to their exhaust position.

De préférence, comme le montre notamment la figure 1, les extrémités 521 et 522 de la biellette 52 s'étendent à la fois transversalement à la direction axiale Z, et transversalement à la portion médiane de la biellette qui relie ces extrémités.Preferably, as shown in particular by figure 1 , the ends 521 and 522 of the rod 52 extend both transversely to the axial direction Z, and transversely to the median portion of the link connecting these ends.

Il est ainsi possible de prévoir que l'extrémité 522 de la biellette 52 appuie directement sur l'extrémité 412 du ressort 41 sans le recours d'une pièce supplémentaire.It is thus possible to provide that the end 522 of the link 52 bears directly on the end 412 of the spring 41 without the use of an additional piece.

De manière avantageuse, l'épaulement 61 peut venir de matière avec la paroi de fond 10 dont le boîtier 1 est doté.Advantageously, the shoulder 61 may be integral with the bottom wall 10 of which the housing 1 is provided.

Le cliquet 62 est par exemple monté pivotant sur la face postérieure 31 du chariot 3, c'est-à-dire sur la face du chariot 3 qui se trouve disposée en regard de la paroi de fond 10 du boîtier 1.The pawl 62 is for example pivotally mounted on the rear face 31 of the carriage 3, that is to say on the face of the carriage 3 which is arranged facing the bottom wall 10 of the housing 1.

Dans ce cas, il est préférable que l'extrémité 522 de la biellette 52 traverse également la face antérieure 32 du chariot 3, c'est-à-dire la face de ce chariot qui est disposée parallèlement et à distance de la face postérieure 31.In this case, it is preferable that the end 522 of the rod 52 also crosses the front face 32 of the carriage 3, that is to say the face of this carriage which is arranged parallel and at a distance from the rear face 31 .

Il peut également être judicieux de prévoir que la face postérieure 31 du chariot 3 présente une fente 310 parallèle à la direction axiale Z, et que cette fente 310 soit traversée par l'extrémité 522 de la biellette 52 pour pouvoir assurer le guidage de cette extrémité 522.It may also be wise to provide that the rear face 31 of the carriage 3 has a slot 310 parallel to the axial direction Z, and that this slot 310 is traversed by the end 522 of the rod 52 to be able to guide this end 522.

Pour optimiser la stabilité du cliquet 62 et réduire l'encombrement des moyens de retenue 6, la came 621 du cliquet 62 est avantageusement disposée entre l'axe de pivotement X et la surface d'appui 623 de ce cliquet 62.To optimize the stability of the pawl 62 and reduce the bulk of the retaining means 6, the cam 621 of the pawl 62 is advantageously arranged between the pivot axis X and the bearing surface 623 of this pawl 62.

Le cliquet 62 peut aussi comprendre une autre came 622, qui s'étend de façon au moins approximativement parallèle à la came 621 et qui est disposée entre cette came 621 et l'axe de pivotement X du cliquet 62.The pawl 62 may also comprise another cam 622, which extends at least approximately parallel to the cam 621 and which is disposed between this cam 621 and the pivot axis X of the pawl 62.

L'extrémité 522 de la biellette 52 peut alors coopérer avec cette deuxième came 622 pour provoquer, au passage du chariot 3 de sa position finale d'enclenchement à sa position inactive, un pivotement correspondant du cliquet 62 dans le sens d'un armement A autour de son axe de pivotement X (figure 3), ce pivotement permettant de replacer la surface d'appui 623 du cliquet 62 en position latente d'engagement avec l'épaulement 61 du boîtier 1 sans requérir le recours à un ressort supplémentaire.The end 522 of the rod 52 can then cooperate with this second cam 622 to cause, when the carriage 3 passes from its final inoperative position to its inactive position, a corresponding pivoting of the pawl 62 in the direction of an armament A around its pivot axis X ( figure 3 ), this pivoting to replace the bearing surface 623 of the pawl 62 in latent position of engagement with the shoulder 61 of the housing 1 without requiring the use of an additional spring.

Comme le montre également la figure 3, le cliquet 62 peut présenter une lumière 620 délimitée par un bord fermé et disposée entre l'axe de pivotement X et la surface d'appui 623 de ce cliquet 62, de sorte que chacune des cames 621 et 622 de ce cliquet peut être définie par une portion correspondante du bord de cette lumière 620.As also shows figure 3 , the pawl 62 may have a light 620 delimited by a closed edge and disposed between the pivot axis X and the bearing surface 623 of this pawl 62, so that each of the cams 621 and 622 of this pawl can be defined by a corresponding portion of the edge of this light 620.
