Description

La présente invention concerne un bloc de contact auxiliaire destiné à être positionné sur un contacteur électrique, sur la face avant ou sur une face latérale de celui-ci.The present invention relates to an auxiliary contact block intended for be positioned on an electrical switch, on the front panel or on a side face of it.

Un tel bloc de contact auxiliaire renferme un contact faisant partie d'un circuit auxiliaire, ledit contact étant commandé en fermeture et ouverture par le coulisseau du contacteur électrique de manière à mettre sous et hors tension ledit circuit auxiliaire.Such an auxiliary contact block contains a contact forming part of a auxiliary circuit, said contact being controlled in closing and opening by the slide of the electrical contactor so as to put under and de-energizing said auxiliary circuit.

Le contact auxiliaire est usuellement un contact à double coupure, il est composé de deux contacts fixes solidaires du boítier et reliés électriquement à deux bornes accessibles de l'extérieur du boítier, et d'un pont mobile porté par un coulisseau auxiliaire, ledit pont mobile portant deux contacts destinés à être mis en contact avec les contacts fixes.The auxiliary contact is usually a double break contact, it is composed of two fixed contacts secured to the housing and connected electrically at two terminals accessible from the outside of the box, and a movable bridge carried by an auxiliary slide, said movable bridge carrying two contacts intended to be brought into contact with the fixed contacts.

Le pont mobile est disposé perpendiculairement au coulisseau et les deux contacts fixes sont disposés dans un plan parallèle audit pont mobile.The movable bridge is arranged perpendicular to the slide and the two fixed contacts are arranged in a plane parallel to said movable bridge.

Le coulisseau auxiliaire du bloc auxiliaire sur lequel est monté le pont mobile est lié en déplacement au coulisseau du contacteur.The auxiliary slide of the auxiliary block on which the bridge is mounted moving is linked in displacement to the slide of the contactor.

Le déplacement de l'ensemble constitué par le coulisseau du contacteur et le coulisseau secondaire s'effectue longitudinalement suivant une direction perpendiculaire à la ligne des contacts fixes.The displacement of the assembly constituted by the slide of the contactor and the secondary slide takes place longitudinally along a direction perpendicular to the line of fixed contacts.

Cette disposition, bien qu'usuellement mise en oeuvre, présente certains inconvénients. Il est tout d'abord nécessaire d'adapter la course du coulisseau secondaire à celle du coulisseau du contacteur ou d'introduire des moyens élastiques autorisant la poursuite de la course du coulisseau du contacteur après la mise en contact des contacts secondaires. This provision, although usually implemented, presents certain disadvantages. It is first of all necessary to adapt the stroke of the secondary slide to that of the contactor slide or to introduce elastic means allowing the continuation of the slide stroke of the contactor after contacting the secondary contacts.

Lors de la fermeture du contact, le pont mobile est amené au contact des contacts fixes afin de fermer le circuit secondaire relié à ces contacts puis reste en appui contre ces contacts fixes durant la fin du mouvement du coulisseau du contacteur tandis que les moyens élastiques sont comprimés et exercent une pression sur ledit pont mobile. Au cours de l'ouverture du contact, les moyens élastiques reprennent leur état antérieur puis le coulisseau secondaire est rappelé en position de repos par le coulisseau du contacteur pour éloigner le pont mobile des contacts fixes.When the contact is closed, the movable bridge is brought into contact with the fixed contacts to close the secondary circuit connected to these contacts then rests against these fixed contacts during the end of the movement of the contactor slide while the elastic means are compressed and exert pressure on said movable bridge. During opening of the contact, the elastic means resume their state anterior then the secondary slide is returned to the rest position by the contactor slide to move the movable bridge away from the contacts fixed.

L'introduction de moyens élastiques dans le déplacement des coulisseaux entraíne l'apparition de phénomènes de rebonds intempestifs du pont mobile qui, d'une part dégradent la qualité du contact secondaire, et d'autre part ne permettent pas de connaítre de manière exacte le moment de la fermeture du contact secondaire.The introduction of elastic means in the displacement of the slides causes the appearance of untimely bouncing of the bridge mobile which, on the one hand degrade the quality of the secondary contact, and on the other hand do not allow to know exactly the moment closing the secondary contact.

Afin d'éviter ces inconvénients, il a par exemple été proposé dans le US 4 712 079 un bloc auxiliaire comportant un contact secondaire constitué d'un premier contact fixe monté sur une paroi du boítier et d'un second contact mobile porté par l'extrémité libre d'un bras articulé sur le boítier et s'étendant entre le coulisseau secondaire et la paroi du boítier portant ledit premier contact fixe. Le coulisseau secondaire dudit bloc auxiliaire présente, sur sa paroi parallèle à la paroi du boítier portant le premier contact fixe, deux surfaces parallèles entre elles, disposées axialement l'une à la suite de l'autre et raccordées par une paroi oblique. Par cette disposition, l'une des surfaces est plus proche de la paroi du boítier que l'autre. Lorsque le coulisseau secondaire est entraíné en translation au cours de la fermeture ou de l'ouverture du contacteur, l'état du contact secondaire est modifié, il est fermé lorsque la surface du coulisseau la plus proche de la paroi portant le premier contact fixe est au contact du bras articulé et ouvert lorsque la surface du coulisseau la plus éloignée de la paroi portant le premier contact fixe est au contact dudit bras articulé.In order to avoid these drawbacks, it has for example been proposed in the US 4,712,079 an auxiliary block comprising a secondary contact consisting of a first fixed contact mounted on a wall of the housing and a second mobile contact carried by the free end of an articulated arm on the case and extending between the secondary slide and the wall of the case carrying said first fixed contact. The secondary slide of said block auxiliary present, on its wall parallel to the wall of the housing carrying the first fixed contact, two surfaces parallel to each other, arranged axially one after the other and connected by an oblique wall. By this arrangement, one of the surfaces is closer to the wall of the case than the other. When the secondary slide is driven in translation during closing or opening of the contactor, the state of the secondary contact is modified, it is closed when the surface of the slide closest to the wall carrying the first fixed contact is in contact with the articulated and open arm when the surface of the slide further from the wall carrying the first fixed contact is in contact of said articulated arm.

Dans un tel bloc auxiliaire, le contact secondaire est constitué d'un premier et d'un second contacts positionnés l'un en face de l'autre dans deux plans parallèles entre eux et parallèles à la direction de déplacement du coulisseau secondaire et amenés en contact par un moyen porté par ledit coulisseau secondaire et adapté à les déplacer perpendiculairement à sa direction de déplacement.In such an auxiliary block, the secondary contact consists of a first and second contacts positioned opposite one another in two planes parallel to each other and parallel to the direction of travel of the secondary slide and brought into contact by a means carried by said secondary slide and adapted to move them perpendicularly to its direction of travel.

Le positionnement des contacts du bloc auxiliaire dans des plans parallèles à la direction de déplacement du coulisseau principal permet de s'affranchir des problèmes d'adaptation de la course de fermeture du contact auxiliaire à la course du coulisseau du contacteur. En conséquence, les moyens élastiques ne sont plus nécessaires et il est possible de fournir un contact auxiliaire exempt de tout risque de rebonds.The positioning of the contacts of the auxiliary block in planes parallel to the direction of movement of the main slide allows to overcome the problems of adapting the closing stroke of the auxiliary contact at the stroke of the contactor slide. In consequence, the elastic means are no longer necessary and it is possible to provide an auxiliary contact free of any risk of rebounds.

L'invention tend à proposer un bloc de ce type qui soit adapté pour être utilisé dans des installations comportant un circuit de charges capacitives destinées à améliorer le cosinus phi d'une installation. Dans ces dispositifs dits à contact fugitif, le contact auxiliaire est destiné à assurer l'alimentation d'une ou plusieurs résistances (ou selfs) disposées en parallèle avec le contact principal et doit être fermé avant le contact principal du contacteur. On obtient ainsi l'insertion pendant un temps très court des résistances ou selfs entre le moment de la fermeture du contact auxiliaire et son court-circuitage par le contact principal, ce qui permet de réduire la pointe de courant à la fermeture des contacts principaux. The invention aims to propose a block of this type which is adapted to be used in installations with a capacitive load circuit intended to improve the cosine phi of an installation. In these so-called fugitive contact devices, the auxiliary contact is intended to ensure the supply of one or more resistors (or inductors) arranged in parallel with the main contact and must be closed before contact main contactor. The insertion is thus obtained for a very long time. runs resistors or inductors between the time of contact closure auxiliary and its short-circuiting by the main contact, which allows reduce the current surge when the main contacts close.

A cet effet, l'invention concerne un bloc auxiliaire du type comportant un boítier renfermant un dispositif de contact secondaire solidaire de deux bornes accessibles de l'extérieur dudit boítier et un coulisseau secondaire destiné à modifier l'état dudit contact secondaire, destiné à être monté sur un contacteur électrique afin que le coulisseau secondaire soit entraíné par le coulisseau dudit contacteur, ledit contact secondaire étant constitué d'un premier et d'un second contacts positionnés l'un en face de l'autre dans deux plans parallèles entre eux et parallèles à la direction de déplacement du coulisseau secondaire et amenés en contact par un moyen porté par ledit coulisseau secondaire et les déplaçant perpendiculairement à sa direction de déplacement, caractérisé en ce que le moyen porté par le coulisseau secondaire est un ergot disposé en saillie par rapport à sa face avant, tournée vers les lames de contact dudit coulisseau secondaire, ledit ergot pouvant être effacé afin de ne pas agir sur les lames de contact.To this end, the invention relates to an auxiliary block of the type comprising a housing containing a secondary contact device integral with two terminals accessible from outside said housing and a secondary slide intended to modify the state of said secondary contact, intended to be mounted on an electrical contactor so that the secondary slide is driven by the slide of said contactor, said secondary contact being consisting of first and second contacts positioned one opposite the other in two planes parallel to each other and parallel to the direction of displacement of the secondary slide and brought into contact by a means carried by said secondary slide and moving them perpendicular to its direction of travel, characterized in that the means carried by the secondary slide is a lug arranged in projecting from its front face, facing the contact blades of said secondary slide, said lug can be erased so as not to act on the contact blades.

De manière connue et comme visible à la figure 1, le bloc auxiliaire est globalement composé d'un boítier 11 fermé par un couvercle 12 et porte des moyens en forme de crochet 13 et de logement 14 destinés à assurer sa mise en place et son accrochage sur la face avant d'un contacteur non représenté au dessin. A l'intérieur du boítier 11 est disposé un contact secondaire constitué par un premier et un second contacts 21, 31 reliés à des bornes 22, 32 accessibles de l'extérieur du bloc auxiliaire pour la connexion d'un circuit secondaire.In a known manner and as can be seen in FIG. 1, the auxiliary block is generally composed of a housing 11 closed by a cover 12 and door hook-shaped means 13 and housing 14 intended to ensure its installation and its attachment to the front face of a non-contactor shown in the drawing. Inside the housing 11 is arranged a contact secondary consisting of first and second contacts 21, 31 connected to terminals 22, 32 accessible from outside the auxiliary unit for the connection of a secondary circuit.

Le bloc auxiliaire comporte encore un coulisseau auxiliaire 104 destiné à être entraíné en déplacement longitudinal par le coulisseau (non représenté au dessin) du contacteur auquel il est relié par les moyens d'accrochage 41.The auxiliary unit also includes an auxiliary slide 104 intended to be driven in longitudinal displacement by the slide (not shown in the drawing) of the contactor to which it is connected by the means attachment 41.

Les contacts 21, 31 sont positionnés l'un en face de l'autre dans deux plans parallèles entre eux et parallèles à la direction de déplacement du coulisseau 104. The contacts 21, 31 are positioned opposite one another in two planes parallel to each other and parallel to the direction of travel of the slide 104.

Ces contacts 21 et 31 sont constitués par des pastilles, par exemple en argent, disposées sur des lames conductrices 2 et 3. Dans l'exemple de réalisation représenté au dessin, la lame 2 est maintenue dans le boítier 11 en positionnant des ouvertures 23 qu'elle présente sur des colonnes 15 du fond du boítier 11. La première lame 2 est ainsi disposée près du fond dudit boítier.These contacts 21 and 31 are constituted by pads, for example in silver, arranged on conductive strips 2 and 3. In the example of embodiment shown in the drawing, the blade 2 is held in the housing 11 by positioning openings 23 which it has on columns 15 from the bottom of the housing 11. The first blade 2 is thus disposed near the bottom said housing.

La lame 2 présente des pliages à angle droit de manière à positionner la borne 22 dans un plan parallèle à celui du contact 21 et plus éloigné du fond du boítier 11 afin qu'elle s'étende dans le logement latéral 17 du bloc auxiliaire.The blade 2 has bends at right angles so as to position the terminal 22 in a plane parallel to that of contact 21 and further from bottom of the housing 11 so that it extends into the lateral housing 17 of the auxiliary block.

La lame 3 est entièrement dans un même plan et présente une forme en U allongé de manière à positionner le contact 31 à l'extrémité d'une branche élastique 35. La branche élastique 35 portant le contact 31 se prolonge par une extension à angle droit 37 présentant une zone de dimensions réduites 36. La borne 32 est disposée à l'extrémité de la seconde branche 34 du U et s'étend dans le logement latéral 18 du bloc auxiliaire.The second blade 3 carrying the second contact 31 and the terminal 32 is held in the housing 11 by positioning openings 33 that it present on columns 16 of the housing 11. The blade 3 is entirely in the same plane and has an elongated U shape so that position the contact 31 at the end of an elastic branch 35. The elastic branch 35 carrying the contact 31 is extended by an extension at right angles 37 having an area of reduced dimensions 36. The terminal 32 is arranged at the end of the second branch 34 of the U and extends in the lateral housing 18 of the auxiliary unit.

Suivant des variantes de réalisation non représentées au dessin, la lame 2 peut être plane et/ou la lame 3 peut être limitée à la branche élastique 35. Dans ces cas, la borne 22 serait proche du fond du boítier 11 et/ou la borne 32 serait près de la paroi du bloc auxiliaire en appui sur le contacteur.According to variant embodiments not shown in the drawing, the blade 2 can be flat and / or the blade 3 can be limited to the elastic branch 35. In these cases, the terminal 22 would be close to the bottom of the housing 11 and / or the terminal 32 would be near the wall of the auxiliary block bearing on the contactor.

La disposition représentée au dessin est préférée car elle permet de positionner les logements latéraux 17, 18 dans lesquels s'étendent les bornes 22, 32 près de la face avant libre 19 du bloc auxiliaire et globalement sur l'axe vertical des parois latérales pour faciliter le branchement du circuit secondaire.The arrangement shown in the drawing is preferred because it allows position the lateral housings 17, 18 in which the terminals 22, 32 near the free front face 19 of the auxiliary unit and generally on the vertical axis of the side walls to facilitate secondary circuit connection.

La seconde lame 3 est fixée sur une nervure du fond du boítier 11 afin de s'étendre à distance du fond du boítier 11 et à distance de la lame 2.The second blade 3 is fixed on a rib at the bottom of the housing 11 in order to extend away from the bottom of the housing 11 and away from the blade 2.

Comme visible au dessin, le coulisseau 104 porte un ergot 142 disposé en saillie par rapport à sa face avant, tournée vers les lames de contact 2 et 3, près de son extrémité libre 45. Ledit ergot s'étend en direction des lames de contact 2, 3 et du fond du boítier 11. La face 43 de l'ergot qui est tournée vers l'extrémité libre 45 du coulisseau est perpendiculaire à la face avant, dudit coulisseau 104. La face opposée 44 de l'ergot 142 est arrondie afin que l'épaisseur dudit ergot 142 diminue à mesure que l'on se rapproche de son extrémité éloignée de l'extrémité libre 45 du coulisseau.As visible in the drawing, the slide 104 carries a lug 142 arranged projecting from its front face, facing the contact blades 2 and 3, near its free end 45. Said lug extends in the direction of the contact blades 2, 3 and the bottom of the housing 11. The face 43 of the lug which is facing the free end 45 of the slide is perpendicular to the front face, of said slide 104. The opposite face 44 of the lug 142 is rounded so that the thickness of said lug 142 decreases as we approaches its far end from the free end 45 of the slide.

Lorsque le coulisseau 104 est en position de repos dans le bloc auxiliaire (figure 2), les lames 2 et 3 sont, dans l'exemple de réalisation représenté au dessin, positionnées entre l'ergot 142 et l'extrémité du coulisseau 104 par laquelle il est accroché au coulisseau du contacteur.When the slide 104 is in the rest position in the auxiliary unit (Figure 2), the blades 2 and 3 are, in the embodiment shown in the drawing, positioned between the lug 142 and the end of the slide 104 by which it is attached to the contactor slide.

Lorsque le coulisseau secondaire 104 est tiré par le coulisseau du contacteur vers la position de fermeture du contact auxiliaire, l'ergot 142 entre en contact par sa face arrondie 44 avec la zone de dimensions réduites 36 de l'extension 37 de la lame 3.When the secondary slide 104 is pulled by the slide of the switch to the closed position of the auxiliary contact, lug 142 comes into contact by its rounded face 44 with the area of dimensions reduced 36 from extension 37 of blade 3.

Compte tenu de son élasticité, la branche 35 de la lame 3 qui n'est tenue contre le boítier 11 que par son pied, est poussée en direction de la lame 2.Given its elasticity, the branch 35 of the blade 3 which is not held against the housing 11 that by its foot, is pushed towards the blade 2.

Les épaisseurs de l'ergot 142, des lames 2 et 3 et des contacts 21 et 31 sont telles qu'au cours de la course du coulisseau 104, les contacts 21 et 31 sont mis en appui l'un contre l'autre, le contact auxiliaire est fermé. The thicknesses of lug 142, blades 2 and 3 and contacts 21 and 31 are such that during the stroke of the slide 104, the contacts 21 and 31 are pressed against each other, the auxiliary contact is closed.

Afin d'assurer un appui de bonne qualité d'un contact sur l'autre, la lame 2 est écartée du fond du boítier 11 afin de pouvoir se déplacer élastiquement et l'épaisseur de l'ergot 42 est telle que le contact 31 appuie sur le contact 21 et repousse élastiquement la lame 2.To ensure good quality support from one contact to the other, the blade 2 is moved away from the bottom of the housing 11 in order to be able to move elastically and the thickness of the pin 42 is such that the contact 31 presses on contact 21 and resiliently pushes blade 2 back.

La zone de dimensions réduites 36 de la lame de contact 3 remplit plusieurs rôles. Elle assure un guidage de l'ergot 142 au cours de son déplacement en face de ladite lame 3 par l'appui des bords latéraux de l'échancrure 38 sur les côtés de l'ergot 142. Le fond de l'échancrure 38 est par exemple arrondi pour faciliter le glissement relatif de l'ergot 142 sur la lame 3 et le déplacement transversal de ladite lame 3. Enfin, la définition de la dimension de ladite zone 36 et de sa position transversale sur la lame 3 permet de régler de manière exacte le moment où l'ergot 142 commence à déplacer la lame 3 en direction de la lame 2 et le moment où se produit la fermeture du contact auxiliaire au cours du mouvement du coulisseau du contacteur.The reduced-size zone 36 of the contact blade 3 fills several roles. It guides the lug 142 during its displacement in front of said blade 3 by the support of the lateral edges of the notch 38 on the sides of the lug 142. The bottom of the notch 38 is for example rounded to facilitate the relative sliding of the lug 142 on the blade 3 and the transverse displacement of said blade 3. Finally, the definition of the dimension of said zone 36 and of its transverse position on the blade 3 allows you to adjust exactly when the lug 142 begins to move blade 3 towards blade 2 and the moment when the auxiliary contact closes during movement of the contactor slide.

Le bloc auxiliaire selon l'invention est destiné à assurer la fermeture du contact auxiliaire pendant un temps très court au cours de la fermeture du contact principal, ledit contact auxiliaire étant ouvert après la fermeture du contact principal ainsi que pendant la phase d'ouverture dudit contact principal.The auxiliary unit according to the invention is intended to ensure the closing of the auxiliary contact for a very short time during closing of the main contact, said auxiliary contact being open after the closing of the main contact as well as during the opening phase of said main contact.

Une telle disposition, dite à contact fugitif, est actuellement obtenue en mettant en oeuvre des dispositifs très complexes faisant appel à des moyens de débrayage de l'entraínement du coulisseau secondaire par le coulisseau du contacteur ou à des moyens comportant plusieurs étages de pièces pouvant coulisser ou non par rapport à celles qui les porte suivant le moment de la course du coulisseau. Such an arrangement, known as a fugitive contact, is currently obtained in using very complex devices using means for disengaging the drive of the secondary slide by the contactor slide or to means comprising several stages of parts which can slide or not with respect to those which carry them according to the moment of the slide stroke.

Avec un bloc auxiliaire selon l'invention, le but recherché est atteint simplement en prévoyant que l'ergot puisse être effacé afin de ne plus agir sur la lame de contact 3.With an auxiliary block according to the invention, the desired goal is achieved simply by providing that the lug can be erased so as not to act on the contact blade 3.

A cet effet, l'ergot 142 est formé sur une languette 140 montée mobile en rotation sur le coulisseau 104.To this end, the lug 142 is formed on a tongue 140 mounted movable in rotation on slide 104.

Ladite languette 140 porte un axe de pivotement 143 positionné à son extrémité libre proche de l'ergot 142. Elle est disposée dans un logement du coulisseau 104 constitué d'une cuvette 124 disposée dans la face arrière 114 de celui-ci, c'est-à-dire la face opposée à celle disposée en regard des lames de contact 2 et 3, et d'une fente axiale traversante 134 communiquant avec ladite cuvette 124.Said tongue 140 carries a pivot axis 143 positioned at its free end close to lug 142. It is placed in a housing slide 104 consisting of a bowl 124 arranged in the face rear 114 thereof, that is to say the face opposite to that arranged in look of the contact blades 2 and 3, and of a through axial slot 134 communicating with said bowl 124.

La cuvette 124 comporte des berceaux 144 assurant la mise en place par encliquetage et le maintien avec possibilité de rotation de l'axe de pivotement 143 de la languette 140.The bowl 124 includes cradles 144 ensuring the establishment by latching and holding with possibility of rotation of the axis of pivot 143 of the tongue 140.

Par cette disposition, l'ergot 142 peut s'effacer dans la fente axiale 134 lorsque l'axe de pivotement 143 tourne sur lui-même.By this arrangement, the lug 142 can be erased in the axial slot 134 when the pivot axis 143 rotates on itself.

Dans la première forme de réalisation du coulisseau 104 représentée aux figures 1 à 4, la languette 140 comporte encore une queue 145 terminée par un embout cylindrique 146.In the first embodiment of the slide 104 shown in Figures 1 to 4, the tongue 140 still has a tail 145 finished by a cylindrical tip 146.

La queue 145 de la languette 140 est flexible et l'embout cylindrique 146 qu'elle porte est disposé dans une lumière 154 formée dans le corps du coulisseau 104 perpendiculairement à la fente axiale 134.The tail 145 of the tongue 140 is flexible and the cylindrical tip 146 that it carries is disposed in a light 154 formed in the body of the slide 104 perpendicular to the axial slot 134.

Comme décrit plus haut, lorsque le coulisseau 104 est tiré par le coulisseau du contacteur, la face 44 de l'ergot 142 déplace l'extension 37 de la lame de contact 3 en direction de la lame de contact 2 jusqu'à ce que le contact secondaire 31-21 soit fermé. Au cours de la poursuite du déplacement du coulisseau, l'ergot 142 franchit la zone des contacts 21-31 de sorte que la face 44 se trouve dans une position pour laquelle elle n'est plus en contact avec la lame de contact 3, celle-ci reprend sa position de repos et le contact secondaire s'ouvre. Les dimensions des pièces sont prévues de telle sorte que l'ouverture du contact secondaire ait lieu lorsque le contact principal est fermé.As described above, when the slide 104 is pulled by the contactor slide, face 44 of lug 142 moves extension 37 from the contact blade 3 towards the contact blade 2 until that the secondary contact 31-21 is closed. During the pursuit of displacement of the slide, the lug 142 crosses the contact area 21-31 so that the face 44 is in a position for which it is no longer in contact with the contact blade 3, it resumes its rest position and the secondary contact opens. The dimensions of parts are provided so that the opening of the secondary contact takes place when the main contact is closed.

Au cours de la remontée du coulisseau 104, lors de l'ouverture du contact principal, l'ergot 142 bute par sa face 43 contre l'extension 37 de la lame de contact 3. La forme de la face 43 n'étant pas adaptée à entraíner le déplacement de la lame de contact 3, l'ergot 142 s'efface par la rotation de l'axe de pivotement 143 dans le berceau 144.During the ascent of the slide 104, when the contact opens main, lug 142 abuts by its face 43 against the extension 37 of the blade contact 3. The shape of the face 43 is not adapted to cause the displacement of the contact blade 3, the lug 142 is erased by the rotation of the pivot axis 143 in the cradle 144.

Lorsque l'ergot 142 s'efface dans la fente axiale 134, la forme arquée de la queue 145 s'accentue et l'embout cylindrique 146 se déplace dans la lumière 154.When the lug 142 disappears in the axial slot 134, the arcuate shape of the tail 145 is accentuated and the cylindrical end piece 146 moves in the light 154.

L'ergot 142 reprend sa position de repos pour laquelle il dépasse de la face avant du coulisseau 104 lorsque celui-ci a atteint sa position de repos.The lug 142 returns to its rest position for which it protrudes from the front face of the slide 104 when it has reached its position of rest.

Dans la forme de réalisation représentée aux figures 5 et 6, la languette 340 est limitée à sa portion comportant l'axe de pivotement 143 et l'ergot 142, la fente axiale 334 est en conséquence limitée à la zone nécessaire pour l'effacement dudit ergot 142.In the embodiment shown in Figures 5 and 6, the tongue 340 is limited to its portion comprising the pivot axis 143 and the lug 142, the axial slot 334 is consequently limited to the necessary area for erasing said lug 142.

L'ergot 142 est ramené dans sa position de repos pour laquelle il dépasse de la face avant du coulisseau 304 par un moyen élastique tel que le ressort 5 représenté au dessin. Le ressort 5 comporte des spires 53 disposées autour de l'axe de pivotement 143, un embout 54 en appui contre le fond de la cuvette 124 et un embout en appui dans une rainure 149 formée dans la face arrière de l'ergot 142.The lug 142 is returned to its rest position for which it exceeds of the front face of the slide 304 by an elastic means such as the spring 5 shown in the drawing. Spring 5 has turns 53 arranged around the pivot axis 143, a tip 54 bearing against the bottom of the bowl 124 and a nozzle resting in a groove 149 formed in the rear face of lug 142.
