Description

L'invention est relative aux appareils électriques à coupure automatique, notamment aux interrupteurs différentiels, disjoncteurs ou disjoncteurs différentiels, du genre de ceux qui comportent une chambre de coupure (ou plus exactement une chambre d'extinction d'arc de coupure) qui est fermée de tous côtés à l'exception d'une ouverture pour le passage d'au moins un contact mobile coopérant avec un contact fixe et qui contient des armatures capables de créer un champ magnétique de désionisation lors du mouvement de séparation des rivets de contact, ou éléments analogues, des contacts fixe(s) et mobile(s).The invention relates to electrical devices with automatic cut-off, in particular differential switches, circuit-breakers or differential circuit-breakers, of the type which include a cut-off chamber (or more precisely a cut-off arc extinguishing chamber) which is closed. on all sides with the exception of an opening for the passage of at least one movable contact cooperating with a fixed contact and which contains armatures capable of creating a magnetic deionization field during the movement of separation of the contact rivets, or similar elements, fixed and mobile contacts.

L'invention a pour but de faciliter le montage de ces appareils.The invention aims to facilitate the mounting of these devices.

A cet effet, la chambre de coupure est aménagée dans un bloc autonome en matière isolante qui est agencé de manière à recevoir, séparément ou sous forme d'ensembles ou sous-ensembles, la plupart des éléments électriques et mécaniques de l'appareil et qui est associé à un socle en matière isolante, le bloc et le socle étant munis de moyens de pivotement, de guidage et de positionnement mutuels tels que le socle puisse être approché du bloc garni des susdits éléments, amené à la position définitive de montage par pivotement par rapport au bloc et maintenu à cette position définitive à l'aide d'une vis unique traversant le socle et serrée dans le bloc, l'ensemble étant complété par un capot entourant le bloc et rapporté sur le socle.To this end, the breaking chamber is arranged in an autonomous block of insulating material which is arranged so as to receive, separately or in the form of assemblies or sub-assemblies, most of the electrical and mechanical elements of the apparatus and which is associated with a base made of insulating material, the block and the base being provided with means of pivoting, guiding and mutual positioning such that the base can be approached from the block furnished with the above elements, brought to the final mounting position by pivoting relative to the block and maintained in this final position using a single screw passing through the base and tightened in the block, the assembly being completed by a cover surrounding the block and attached to the base.

Le susdit bloc remplit ainsi la double fonction d'un gabarit de montage et d'une ossature de l'appareil et il est facile de l'adapter et de le fixer au socle.The above block thus fulfills the dual function of a mounting template and a framework of the device and it is easy to adapt and fix it to the base.

Selon un mode de réalisation préféré dans lequel le ou chaque contact mobile est muni d'un ressort de mise en pression, ce ressort est maintenu sur le socle alors que le contact mobile correspondant est maintenu sur le bloc, de telle sorte que la fixation du socle au bloc à l'aide de la susdite vis unique assure la compression du ressort et par conséquent la mise en pression du contact mobile correspondant.According to a preferred embodiment in which the or each movable contact is provided with a pressurizing spring, this spring is held on the base while the corresponding movable contact is maintained on the block, so that the fixing of the base to the block using the aforementioned single screw ensures the compression of the spring and consequently the pressurization of the corresponding movable contact.

Ce mode de réalisation fait ainsi jouer à la vis de fixation un rôle supplémentaire, ce qui simplifie la construction de l'appareil.This embodiment thus makes the fixing screw play an additional role, which simplifies the construction of the device.

Conformément à un autre perfectionnement, la chambre de coupure est fermée latéralement par un couvercle rapporté sur le bloc et une platine sert à la fois au maintien du couvercle sur le bloc et au support d'un bouton-test de type connu.In accordance with another improvement, the breaking chamber is closed laterally by a cover attached to the block and a plate is used both for holding the cover on the block and for supporting a test button of known type.

Là encore, une même pièce remplit une double fonction, ce qui simplifie encore la construction de l'appareil.Here again, the same part fulfills a double function, which further simplifies the construction of the apparatus.

Il est à noter que le US-A-3 178 547 décrit un coupe-circuit dont les seuls éléments mobiles du mécanisme de coupure sont portés par une pièces en U (31) qui est fixée à un socle (11) par engagement d'un crochet (45), porté de chaque côté par la pièce en U (31), dans l'encoche d'une équerre (47) qui est fixée par une vis (48) au socle (11). La pièce en U (31) est ensuite fixée au socle (11) par une vis unique (61) qui traverse cette pièce (31) par un trou (62) et qui se visse dans un écrou (63) emprisonné dans le socle (11) au moulage. La tête de la vis unique (61) ne peut être atteinte par un tournevis que de l'intérieur du socle (11), ce qui nécessite de laisser libre dans la pièce en U (31) un espace pour le passage d'un tel tournevis. Sur le socle (11) sont rapportés directement des chambres de coupure à armatures d'extinction (40) et un dispositif de déclenchement automatique à surcharge (21, 97). La pièce en U (31) ne remplit pas ainsi la double fonction d'un gabarit de montage et d'ossature pour l'appareil. De plus, en position de fixation, la pièce en U (31) bute (en 65) sur les deux susdites équerres (47), ce qui rend la position de fixation incertaine.It should be noted that US-A-3,178,547 describes a circuit breaker, the only movable elements of the cutting mechanism of which are carried by a U-shaped piece (31) which is fixed to a base (11) by engagement of a hook (45), carried on each side by the U-shaped piece (31), in the notch a bracket (47) which is fixed by a screw (48) to the base (11). The U-shaped part (31) is then fixed to the base (11) by a single screw (61) which passes through this part (31) through a hole (62) and which is screwed into a nut (63) trapped in the base ( 11) during molding. The head of the single screw (61) can only be reached by a screwdriver from inside the base (11), which requires leaving space in the U-shaped part (31) for the passage of such a screwdriver. On the base (11) are directly connected cut-off chambers with extinguishing armatures (40) and an automatic overload tripping device (21, 97). The U-shaped part (31) thus does not fulfill the dual function of a mounting template and framework for the device. In addition, in the fixing position, the U-shaped part (31) abuts (at 65) on the two above-mentioned brackets (47), which makes the fixing position uncertain.

Le US-A-3 178 547 ne suggère pas non plus d'utiliser le pivotement autour des crochets (47) pour assurer la compression d'un ressort avec mise en pression des contacts mobiles (25).US-A-3,178,547 also does not suggest using the pivoting around the hooks (47) to ensure the compression of a spring with pressurization of the movable contacts (25).

L'invention va être maintenant exposée plus en détail à l'aide des dessins annexés.

L'invention s'applique particulièrement bien à un interrupteur différentiel du genre décrit dans la demande de brevet français FR-A-2 552 931 déposée par la demanderesse le 4 octobre 1983.The invention applies particularly well to a differential switch of the kind described in French patent application FR-A-2 552 931 filed by the applicant on October 4, 1983.

Selon cette demande de brevet, l'interrupteur différentiel comprend, comme le montre notamment la figure 6, un mécanisme à genouillère et à encliquetage 1, entre un organe rotatif d'actionnement manuel ou manette 2 à bouton d'actionnement 2a et un porte-contact basculant 3 sur lequel est monté au moins un contact mobile 4 coopérant avec un contact fixe 5 et qui est sollicité par un premier ressort 6 dans le sens de l'ouverture ou séparation du contact mobile 4 par rapport au contact fixe 5.According to this patent application, the differential switch comprises, as shown in particular in Figure 6, a toggle and snap mechanism 1, between a rotary manual actuation member or lever 2 with actuation button 2a and a holder tilting contact 3 on which is mounted at least one movable contact 4 cooperating with a fixed contact 5 and which is biased by a first spring 6 in the direction of opening or separation of the movable contact 4 relative to the fixed contact 5.

Il existe en général deux contacts mobiles 4 coopérant respectivement avec deux contacts fixes 5 et sollicités chacun par un ressort 6. L'ensemble du porte-contact 3 et du ou des contacts mobiles 4 est de préférence agencé de la façon décrite dans la demande de brevet français FR-A-2 552 926 déposée par la demanderesse le 4 octobre 1983 , c'est-à-dire de façon que le(s) même(s) ressort(s) 6 assure(nt) à la fois la séparation des contacts 4 et 5 lors du mouvement d'ouverture et la pression de ces contacts 4, 5 l'un sur l'autre en position de fermeture. Le mécanisme 1 est capable, d'une part, lorsqu'il est tendu, de transmetre le mouvement de la manette 2 au porte-contact 3 aussi bien dans le sens de l'ouverture que dans le sens de la fermeture et, d'autre part, au moment où le mécanisme 1 est détendu par un relais 7 agissant indépendamment de la manette 2 sur l'encliquetage du mécanisme 1, de provoquer le retour du porte-contact 3 de sa position de fermeture à sa position d'ouverture. Le mécanisme 1 est agencé de manière à permettre à la manette 2 de réarmer l'interrupteur, c'est-à-dire de retendre le mécanisme 1 en le ramenant de sa position d'ouverture après déclenchement à sa position d'ouverture normale représentée à la figure 6, après cessation de l'intervention du relais 7 et sous l'action d'un deuxième ressort 8 agissant sur cette manette 2.There are generally two movable contacts 4 cooperating respectively with two fixed contacts 5 and each biased by a spring 6. The assembly of the contact carrier 3 and of the movable contact (s) 4 is preferably arranged as described in the request for French patent FR-A-2,552,926 filed by the plaintiff on October 4, 1983, that is to say so that the same spring (s) 6 ensure (s) both the separation contacts 4 and 5 during the opening movement and the pressure of these contacts 4, 5 one on the other in the closed position. The mechanism 1 is capable, on the one hand, when it is tensioned, of transmitting the movement of the lever 2 to contact carrier 3 both in the opening direction and in the closing direction and, on the other hand, when the mechanism 1 is released by a relay 7 acting independently of the lever 2 on the snap of the mechanism 1, to cause the contact carrier 3 to return from its closed position to its open position. The mechanism 1 is arranged so as to allow the lever 2 to reset the switch, that is to say to tighten the mechanism 1 by returning it from its open position after tripping to its normal open position shown in FIG. 6, after the intervention of the relay 7 has ceased and under the action of a second spring 8 acting on this lever 2.

De façon usuelle, l'interrupteur est logé dans un boîtier isolant qui sera décrit plus en détail ci-après et d'où émerge le bouton 2a de la manette 2.Usually, the switch is housed in an insulating box which will be described in more detail below and from which the button 2a of the lever 2 emerges.

Le mécanisme 1 est essentiellement constitué :

  • - d'une bielle 10 articulée par l'une de ses extrémités sur la manette 2, selon un axe 11 excentré par rapport à l'axe de rotation fixe 12 de la manette 2 ;
  • - d'une biellette 13 articulée par l'une de ses extrémités à l'autre extrémité de la bielle 10, selon un axe 14, et par l'autre de ses extrémités au porte-contact 3, selon un axe 15 excentré par rapport à l'axe de basculement fixe 16 du porte-contact 3 ; et
  • - d'un levier déclencheur 17 articulé par l'une de ses extrémités autour d'un axe fixe 18 et muni d'une rainure longitudinale 19 dans laquelle l'axe d'articulation 14 entre bielle 10 et biellette 13 peut glisser pratiquement sans jeu transversal.
Mechanism 1 essentially consists of:
  • - A connecting rod 10 articulated by one of its ends on the handle 2, along an axis 11 eccentric relative to the fixed axis of rotation 12 of the handle 2;
  • - A link 13 articulated by one of its ends to the other end of the rod 10, along an axis 14, and by the other of its ends to the contact carrier 3, along an axis 15 eccentric relative to to the fixed tilting axis 16 of the contact carrier 3; and
  • a trigger lever 17 articulated by one of its ends around a fixed axis 18 and provided with a longitudinal groove 19 in which the axis of articulation 14 between connecting rod 10 and connecting rod 13 can slide practically without play transverse.

Les susdits axes 11, 12, 14, 15, 16 et 18 sont parallèles les uns aux autres, les axes fixes 12, 16 et 18 étant liés au boîtier.The above axes 11, 12, 14, 15, 16 and 18 are parallel to each other, the fixed axes 12, 16 and 18 being linked to the housing.

L'encliquetage du mécanisme 1 comprend un cliquet 20, d'axe 21, qui est sollicité par un troisième ressort 22, ce cliquet 20 agissant sur le levier déclencheur 17. L'axe 21 est lui aussi parallèle aux axes 11, 12, 14, 15, 16 et 18 et il est lié au boîtier.The latching of the mechanism 1 comprises a pawl 20, of axis 21, which is biased by a third spring 22, this pawl 20 acting on the trigger lever 17. The axis 21 is also parallel to the axes 11, 12, 14, 15, 16 and 18 and it is linked to the housing.

L'axe fixe 18 du levier déclencheur 17 est situé de façon telle que, en position de fermeture, ce levier déclencheur 17 soit approximativement parallèle à l'ensemble de la bielle 10 et de la biellette 13, cet axe étant alors pratiquement aligné avec l'axe 11 entre manette 2 et bielle 10.The fixed axis 18 of the trigger lever 17 is located so that, in the closed position, this trigger lever 17 is approximately parallel to the assembly of the connecting rod 10 and the connecting rod 13, this axis then being practically aligned with the axis 11 between lever 2 and connecting rod 10.

La bielle 10 est constituée d'une tige rectiligne dont les deux' extrémités sont repliées à angle droit de manière à constituer respectivement l'axe d'articulation 11 de la bielle 10 avec la manette 2 et son axe d'articulation 14 avec la biellette 13. Comme montré aussi à la figure 1, la biellette 13 est avantageusement constituée de deux biellettes individuelles parallèles 13a et 13b de façon que la partie 3a du porte-contact 3, par laquelle se fait l'articulation avec la biellette double 13, se place entre les deux biellettes individuelles 13a, 13b. De préférence, une barrette de liaison 43 solidarise ensemble ces deux biellettes individuelles 13a, 13b.The connecting rod 10 consists of a rectilinear rod, the two ends of which are folded at a right angle so as to respectively constitute the articulation axis 11 of the connecting rod 10 with the lever 2 and its articulation axis 14 with the connecting rod 13. As also shown in FIG. 1, the link 13 advantageously consists of two individual parallel links 13a and 13b so that the part 3a of the contact carrier 3, by which the articulation is made with the double link 13, is place between the two individual links 13a, 13b. Preferably, a connecting bar 43 secures these two individual links 13a, 13b together.

La longueur de la rainure 19 du levier déclencheur 17 est telle que l'axe d'articulation 14 entre bielle 10 et biellette 13 vienne buter contre l'une 23 des extrémités longitudinales de cette rainure 19 au cours du mouvement de réarmement.The length of the groove 19 of the trigger lever 17 is such that the articulation axis 14 between connecting rod 10 and connecting rod 13 abuts against one 23 of the longitudinal ends of this groove 19 during the resetting movement.

En général, le relais 7 est un relais à aimant permanent, qui agit par une tige-poussoir 25 sur le cliquet 20, ce qui oblige le cliquet 20 à exercer sur cette tige-poussoir 25 une force suffisante pour vaincre l'action du ressort antagoniste de l'aimant permanent lors du réarmement du relais 7. Pour assurer cette opération, un ressort de réarmement 48 est agencé de façon telle que, lorsque le mécanisme 1 est détendu par action du relais 7, la tension de ce ressort 48 se trouve fortement accrue, par un mouvement d'écartement des deux extrémités de ce ressort. Le cliquet 20 est muni d'une encoche 28 propre à recevoir un bec 30 porté par le levier déclencheur 17.In general, the relay 7 is a permanent magnet relay, which acts by a push rod 25 on the pawl 20, which forces the pawl 20 to exert on this push rod 25 a force sufficient to overcome the action of the spring. antagonist of the permanent magnet during the resetting of the relay 7. To ensure this operation, a resetting spring 48 is arranged in such a way that, when the mechanism 1 is relaxed by action of the relay 7, the tension of this spring 48 is greatly increased, by a movement of separation of the two ends of this spring. The pawl 20 is provided with a notch 28 suitable for receiving a spout 30 carried by the trigger lever 17.

Le boîtier est muni d'autant de bonnes d'entrée 32 que de contacts fixes 5, qui sont reliées électriquement à ces contacts fixes 5. De façon usuelle, le ou chaque contact fixe 5 porte un rivet de contact 33 qui coopère avec un rivet de contact 34 porté par le ou chaque contact mobile 4 correspondant. La continuité du circuit électrique est assurée par une tresse 38 attachée au contact mobile 4. Le rivet 33 est logé en position fixe et le rivet 34 se déplace dans une chambre d'extinction d'arc de coupure ou, plus brièvement, une chambre de coupure 35, qui est fermée de tous côtés à l'exception d'une ouverture 36 nécessaire pour le débattement du contact mobile 4 ou plus exactement de la partie de ce contact mobile 4 qui est voisine de son rivet de contact 34. Comme on le sait, une telle chambre de coupure 35 contient des armatures 37 capables de créer un champ magnétique de désionisation lors de la séparation des rivets de contact 33 et 34.The housing is provided with as many good inputs 32 as fixed contacts 5, which are electrically connected to these fixed contacts 5. Usually, or each fixed contact 5 carries a contact rivet 33 which cooperates with a rivet contact 34 carried by the or each corresponding movable contact 4. The continuity of the electrical circuit is ensured by a braid 38 attached to the movable contact 4. The rivet 33 is housed in a fixed position and the rivet 34 moves in a cut-off arc chamber or, more briefly, a break 35, which is closed on all sides except for an opening 36 necessary for the movement of the movable contact 4 or more exactly of the part of this movable contact 4 which is close to its contact rivet 34. As is knows, such an interrupting chamber 35 contains armatures 37 capable of creating a magnetic deionization field during the separation of the contact rivets 33 and 34.

Du côté opposé à celui des bornes d'entrée 32, le boîtier est muni de bornes de sortie 31.On the side opposite that of the input terminals 32, the box is provided with output terminals 31.

Le relais 7 est relié à un tore de détection de défauts 9 par un enroulement secondaire 24.The relay 7 is connected to a fault detection toroid 9 by a secondary winding 24.

Enfin, l'interrupteur comprend un bouton-test 39 auquel sont associés une résistance 40, un contact souple 41, un ressort de rappel 56 et deux languettes métalliques 57 et 73.Finally, the switch includes a test button 39 with which a resistor 40 is associated, a flexible contact 41, a return spring 56 and two metal tabs 57 and 73.

Le fonctionnement d'ensemble de l'interrupteur est connu et il est donc inutile de le décrire ici.The overall operation of the switch is known and it is therefore unnecessary to describe it here.

Cela étant, conformément à l'invention, la chambre de coupure 35 est aménagée dans un bloc autonome 26 en matière isolante qui est agencé de manière à recevoir, séparément ou sous forme d'ensembles ou sous-ensembles, la plupart des éléments électriques et mécaniques de l'appareil et qui est associé à un socle 27 en matière isolante. Le bloc 26 et le socle 27 sont munis de moyens de pivotement, de guidage et de positionnement mutuels qui seront décrits plus en détail ci-après et tels que le socle 27 puisse être approché du bloc 26 garni des susdits éléments, amené à la position de montage définitive par pivotement par rapport au bloc 26 (ainsi qu'il sera expliqué plus en détail à l'aide de la figure 4) et maintenu à cette position définitive à l'aide d'une vis unique 44 qui traverse le socle 27 par un trou 45 et qui est serrée dans le bloc 26, en s'engageant dans un trou 46 ménagé dans ce dernier. Le boîtier, qui comprend le bloc 26 et le socle 27, est complété par un capot 47 entourant le bloc 26 et rapporté sur le socle 27.However, in accordance with the invention, the breaking chamber 35 is arranged in an autonomous block 26 of insulating material which is arranged so as to receive, separately or in the form of assemblies or subassemblies, most of the electrical elements and mechanical of the device and which is associated with a base 27 of insulating material. The block 26 and the base 27 are provided with mutual pivoting, guiding and positioning means which will be described in more detail below and such that the base 27 can be approached from the block 26 furnished with the above elements, brought to the final mounting position by pivoting relative to the block 26 (as will be explained in more detail with the aid of FIG. 4) and kept at this final position using a single screw 44 which passes through the base 27 through a hole 45 and which is tightened in the block 26, engaging in a hole 46 formed in the latter. The housing, which includes the block 26 and the base 27, is completed by a cover 47 surrounding the block 26 and attached to the base 27.

De préférence, le ressort 6 de mise en pression du ou de chaque contact mobile 4 est maintenu sur le socle 27 (voir la figure 2) alors que le contact mobile 4 correspondant est maintenu sur le bloc 26, de telle sorte que la fixation du socle 27 sur le bloc 26 à l'aide de la vis unique 44 assure la compression du ou de chaque ressort 6 et par conséquent la mise en pression du contact mobile 4 correspondant.Preferably, the spring 6 for pressurizing the or each movable contact 4 is maintained on the base 27 (see FIG. 2) while the corresponding movable contact 4 is maintained on the block 26, so that the fixing of the base 27 on the block 26 using the single screw 44 ensures the compression of the or each spring 6 and consequently the pressurization of the corresponding movable contact 4.

De préférence encore, la chambre de coupure 35 est fermée latéralement par un couvercle 42 rapporté sur le bloc 26 et une platine 29 sert à la fois au maintien du couvercle 42 sur le bloc 26 et au support du bouton-test 39. et des éléments associés à celui-ci. Dans ce cas, les susdits moyens de pivotement, de guidage et de positionnement, qui sont prévus entre le socle 27 et le bloc 26, sont répartis,du côté de ce dernier, entre le bloc 26 et le couvercle 42 qui forment un ensemble rigide après adaptateur de la platine 29.More preferably, the interrupting chamber 35 is closed laterally by a cover 42 attached to the block 26 and a plate 29 is used both for holding the cover 42 on the block 26 and for supporting the test button 39. and elements associated with it. In this case, the aforesaid means of pivoting, guiding and positioning, which are provided between the base 27 and the block 26, are distributed, on the side of the latter, between the block 26 and the cover 42 which form a rigid assembly after plate adapter 29.

On va maintenant décrire les phases successives de montage de l'appareil et, au fur et à mesure, les caractéristiques de construction qui permettent la réalisation de ces phases.

  • 1°) Sous-ensemble porte-contact
    • On introduit l'axe 15 dans les ouvertures 49 des biellettes individuelles 13a, 13b et dans l'ouverture 50 de la partie 3a du porte-contact 3, en accrochant l'une des extrémités du ressort de réarmement 48 à cet axe 15. Puis on introduit deux axes 51 dans des ouvertures 52 du porte-contact 3 (à la droite de sa partie inférieure, la figure 1 représente à l'envers un fragment du porte-contact 3 et l'un des contacts mobiles 4).

On place le ressort de compression 22 sur le cliquet 20. Puis on présente le bec 30 du levier déclencheur 17 dans l'encoche 28 du cliquet 20. On accroche alors une pièce de réarmement 61 à l'autre extrémité du ressort de traction 48 du sous-ensemble porte-contact. On présente alors le sous-ensemble ainsi réalisé sur le bloc 26, en engageant l'un des axes 16 du porte-contact 3 dans un palier 62 du bloc 26 et l'axe 63 de la pièce de réarmement 61 dans un autre palier 64 du bloc 26.
We will now describe the successive phases of assembly of the device and, progressively, the construction characteristics which allow the realization of these phases.
  • 1 °) Contact holder sub-assembly
    • The axis 15 is introduced into the openings 49 of the individual rods 13a, 13b and into the opening 50 of the part 3a of the contact carrier 3, by hooking one of the ends of the reset spring 48 to this axis 15. Then two axes 51 are introduced into the openings 52 of the contact carrier 3 (to the right of its lower part, FIG. 1 shows a fragment of the contact carrier 3 and one of the movable contacts 4 upside down).
  • 2 °) Test sub-assembly:
    • Resistor 40 is introduced into the test button 39 and the flexible contact 41 is placed there, making the necessary smudures.

    • The two springs 6 are fitted onto studs 60 (FIG. 6) provided for this purpose on the base 27.
  • 7 °) Cut-off chamber sub-assembly:
    • The trigger lever 17 is presented on the axis 18 coming from molding with the block 26, then the pawl 20 on the axis 21 also coming from molding with the block 26. The compression spring 22 is placed on the pawl 20. Then the spout 30 of the trigger lever 17 is presented in the notch 28 of the pawl 20. A reset piece 61 is then hooked to the other end of the tension spring 48 of the contact carrier sub-assembly. The sub-assembly thus produced is then presented on the block 26, by engaging one of the axes 16 of the contact carrier 3 in a bearing 62 of the block 26 and the axis 63 of the reset piece 61 in a another level 64 of block 26.

On dispose le ressort de torsion 8 dans la manette 2 et celle-ci sur un axe 65 venu de moulage avec le bloc 26, en plaçant l'extrémité du ressort 8 derrière l'axe 18 du levier déclencheur 17, ce qui retient ce dernier latéralement.There is the torsion spring 8 in the handle 2 and the latter on an axis 65 molded with the block 26, placing the end of the spring 8 behind the axis 18 of the trigger lever 17, which retains the latter laterally.

Par ailleurs, on présente l'axe 14 de la bielle 10 dans des trous 66 de la biellette 13 et dans la rainure 19 du levier déclencheur 17 et l'axe 11 de la bielle 10 dans un palier excentré 67 de la manette 2 en faisant tourner celle-ci pour obtenir l'entraxe de la bielle 10.Furthermore, the axis 14 of the connecting rod 10 is presented in holes 66 of the connecting rod 13 and in the groove 19 of the trigger lever 17 and the axis 11 of the connecting rod 10 in an eccentric bearing 67 of the lever 2 by making turn it to obtain the center distance of the connecting rod 10.

8°) Ensemble bloc et couvercle :

  • On centre le couvercle 42 sur le bloc 26 en présentant l'autre axe 16a du porte-contact 3 dans un palier 68 prévu sur le couvercle 42 et l'autre axe 63 de la pièce de réarmement 61, dans un palier (non montré) prévu également sur le couvercle 42 et en engageant l'extrémité de l'axe 15 dans une lumière en arc de cercle 69 qui traverse le couvercle 42. Puis on verrouille le couvercle 42 sur le bloc 26 en abaissant la platine 29 comme indiqué par la flèche Fl à la figure 2, jusqu'à la position représentée par la vue de détail située en haut et à gauche de la figure 2, ce qui produit un agrafage par engagement de l'aile 55 de la platine 29 dans une encoche 70 du bloc 26 et par accrochage d'un cran 71 du bloc 26 sur le bord d'une ouverture 72 ménagée dans la platine 29.
8 °) Block and cover assembly:
  • The cover 42 is centered on the block 26 with the other axis 16a of the contact carrier 3 in a bearing 68 provided on the cover 42 and the other axis 63 of the reset piece 61, in a bearing (not shown) also provided on the cover 42 and by engaging the end of the axis 15 in a light in an arc 69 which passes through the cover 42. Then the cover 42 is locked on the block 26 by lowering the plate 29 as indicated by the arrow Fl in FIG. 2, up to the position represented by the detail view located at the top left of FIG. 2, which produces a stapling by engagement of the wing 55 of the plate 29 in a notch 70 of the block 26 and by hooking a notch 71 of the block 26 on the edge of an opening 72 formed in the plate 29.

On présente en outre les sous-ensembles de désionisation à armatures 37 dans la chambre de coupure 35 du bloc 26 ainsi que les contacts fixes 5 sur ce bloc 26. On enchâsse la languette de test 73 sur le bloc 26. Enfin, on introduit les deux contacts mobiles 4 dans les logements ménagés à cet effet dans le porte-contact 3 et on agrafe le sous-ensemble relais sur le bloc 26 en introduisant les oreilles 53 garnies des amortisseurs 59 successivement dans des ouvertures 74 du couvercle 42 et 75 du bloc 26, comme représenté dans la vue de détail située à la gauche de la partie supérieure de la figure 3.The armored deionization sub-assemblies 37 are also presented in the breaking chamber 35 of the block 26 as well as the fixed contacts 5 on this block 26. The test tab 73 is embedded on the block 26. Finally, the two movable contacts 4 in the housings provided for this purpose in the contact holder 3 and the relay sub-assembly is stapled to the block 26 by inserting the ears 53 fitted with shock absorbers 59 successively in openings 74 of the cover 42 and 75 of the block 26, as shown in the detail view located to the left of the top of Figure 3.

On obtient ainsi un ensemble fonctionnel complet.A complete functional unit is thus obtained.

9 °) Block-cover-base assembly:
  • The base 27 of the assembly thus formed is approached by the block 26 and by the cover 42 by engaging their mutual pivoting, guiding and positioning means, as shown schematically in FIG. 4.

Ces moyens comprennent avantageusement deux becs 76 et 77 prévus respectivement sur le bloc 26 et le couvercle 42 et deux encoches correspondantes 78 prévues sur le socle 27, l'ensemble étant tel que, lorsque les becs 76, 77 sont enfoncés respectivement dans les encoches 78, on puisse faire pivoter l'ensemble 26, 42 par rapport au socle 27 selon la flèche F2 de la figure 4 ou, plus généralement, le socle 27 par rapport à l'ensemble 26, 42. Ces moyens comprennent, en outre, des rebords 79 entourant le socle 27 et propres à recevoir et à guider entre eux les faces latérales de l'ensemble 26, 42 et celle des faces transversales de cet ensemble qui est la plus éloignée des becs 76, 77. Ces moyens peuvent comprendre en outre des saillies et creux qui sont ménagés sur les éléments 26, 42 et 27 et qui s'engagent les uns dans les autres lors du mouvement de pivotement susvisé.These means advantageously include two spouts 76 and 77 provided respectively on the block 26 and the cover 42 and two corresponding notches 78 provided on the base 27, the assembly being such that, when the spouts 76, 77 are inserted respectively in the notches 78 , the assembly 26, 42 can be pivoted relative to the base 27 according to the arrow F2 in FIG. 4 or, more generally, the base 27 relative to the assembly 26, 42. These means further comprise flanges 79 surrounding the base 27 and suitable for receiving and guiding between them the lateral faces of the assembly 26, 42 and that of the transverse faces of this assembly which is the farthest from the spouts 76, 77. These means may further comprise projections and recesses which are formed on the elements 26, 42 and 27 and which engage with each other during the abovementioned pivoting movement.

Puis on effectue le mouvement de pivotement susvisé, ce qui présente automatiquement les ressorts 6 sur des collerettes 80 (figure 1) prévues à cet effet sur les contacts mobiles 4, puis comprime les ressorts 6. A la fin du mouvement de pivotement, on introduit la vis d'assemblage 44 dans le trou 45 du socle 27 et dans le trou 46 du bloc 26 et on serre la vis 44 dans ce dernier trou 46.Then the above-mentioned pivoting movement is carried out, which automatically presents the springs 6 on flanges 80 (FIG. 1) provided for this purpose on the movable contacts 4, then compresses the springs 6. At the end of the pivoting movement, we introduce the assembly screw 44 in the hole 45 of the base 27 and in the hole 46 of the block 26 and the screw 44 is tightened in this last hole 46.

10°) Opérations finales d'assemblage et de réglage :

  • On présente les bornes 31 dans des logements prévus à cet effet entre les éléments 26, 42 et 27 et on effectue les diverses connexions électriques (le produit ainsi obtenu étant représenté au bas de la figure 5). On procède alors sur ce produit aux réglages de la sensibilité du relais 7 et aux vérifications mécaniques et électriques de l'interrupteur différentiel. Enfin, on adapte sur le produit le capot 47, comme schématisé par les flèches F3 de la figure 5, en introduisant des pattes élastiques d'encliquetage 81, venus de moulage avec le capot 47, dans des encoches 82 prévues à cet effet dans le socle 27 (voir la vue de détail située à la gauche de la figure 5), en faisant passer le bouton 2a de la manette 2 et le bouton- poussoir 39 respectivement par des ouvertures 83 et 84 ménagées dans le capot 47. L'interrupteur différentiel est alors prêt à être utilisé.
