Description

La présente invention est relative à un disjoncteur de phase et neutre comportant, dans un boîtier destiné à être fixé sur un rail, des bornes de raccordement de phase et de neutre, des paires de contacts, fixe et mobile, de phase et de neutre respectivement, des chambres de coupure d'arc respectivement pour les contacts de phase et les contacts de neutre, un mécanisme de commande du type à serrure pour la commande manuelle des contacts mobiles entre une position de fermeture rapprochée des contacts fixes et une position d'ouverture écartée des contacts fixes et des moyens de dis­jonction, notamment thermique et/ou magnétique, pour libérer la serrure et faire passer les contacts de leur position de fermeture à leur position d'ouverture, ainsi qu'une cloison en matériau isolant séparant les contacts de neutre des con­tacts de phase.The present invention relates to a phase and neutral circuit breaker comprising, in a housing intended to be fixed on a rail, phase and neutral connection terminals, pairs of contacts, fixed and mobile, phase and neutral respectively. , arc breaking chambers respectively for phase contacts and neutral contacts, a lock-type control mechanism for manual control of movable contacts between a close position close to the fixed contacts and an open position separated from the fixed contacts and means of disjunction, in particular thermal and / or magnetic, to release the lock and move the contacts from their closed position to their open position, as well as a partition made of insulating material separating the contacts from neutral of phase contacts.

On connaît des disjoncteurs de phase et de neutre de ce type.Phase and neutral circuit breakers of this type are known.

Dans le brevet FR-A-2.167.302, on a voulu réunir, dans un boîtier plat unique, les contacts de phase et de neutre. Ces contacts sont placés au fond du boitier et sont séparés latéralement par une cloison médiane, la bobine de disjonc­tion étant placée en position supérieure dans le boîtier.In patent FR-A-2,167,302, it was desired to combine, in a single flat case, the phase and neutral contacts. These contacts are placed at the bottom of the housing and are separated laterally by a central partition, the circuit breaker being placed in the upper position in the housing.

D'après le brevet FR-A-2.485.254, on connaît également un disjoncteur de phase et neutre à boîtier moulé comprenant un mécanisme de commande disposé dans le plan médian, dans lequel le mécanisme commande simultanément la paire de con­tacts de phase et la paire de contacts de neutre, lesdites paires étant séparées par une cloison isolante intermédiaire, décalée par rapport audit plan médian de façon à confiner une première chambre de paire de contacts de phase et une deuxième chambre de paire de contacts de neutre, le volume de la première chambre étant supérieur à celui de la deuxième chambre.From patent FR-A-2,485,254, there is also known a phase and neutral circuit breaker with molded housing comprising a control mechanism arranged in the median plane, in which the mechanism simultaneously controls the pair of phase contacts and the pair of neutral contacts, said pairs being separated by an intermediate insulating partition, offset with respect to said median plane so as to confine a first chamber of pair of phase contacts and a second chamber of pair of neutral contacts, the volume of the first bedroom being superior to that of the second bedroom.

La demande de brevet européen EP-A-0.252.786 décrit un disjoncteur similaire qui présente une cloison médiane s'étendant sur toute la largeur de l'appareil et ayant une première partie s'étendant dans le plan médian, ainsi qu'une deuxième partie déportée vers l'une des faces latérales du boîtier.European patent application EP-A-0,252,786 describes a similar circuit breaker which has a central partition extending over the entire width of the device and having a first part extending in the median plane, as well as a second part offset to one of the side faces of the housing.

La demande de brevet européen EP-A-0.259.992 décrit également un disjoncteur phase + neutre avec une pièce de structure centrale présentant une cloison isolante définissant les espaces phase et neutre, et pourvue de moyens logeant et maintenant des pièces mécaniques et élec­triques, et deux pièces latérales d'habillage refermant le boîtier ainsi constitué.European patent application EP-A-0,259,992 also describes a phase + neutral circuit breaker with a central structural part having an insulating partition defining the phase and neutral spaces, and provided with means housing and maintaining mechanical and electrical parts, and two side trim pieces closing the casing thus formed.

Ces différentes réalisations permettent de placer, dans un même boîtier, des contacts de phase et de neutre et d'assurer, dans une plus ou moins large mesure, l'isolation de ces contacts entre eux.These different embodiments make it possible to place, in the same housing, phase and neutral contacts and to ensure, to a greater or lesser extent, the isolation of these contacts from each other.

Ces appareils connus sont cependant d'un montage diffi­cile et donc d'un prix de revient élevé. Par ailleurs, ils présentent des inconvénients tels qu'une mauvaise évacuation des flux thermiques qui peuvent entraîner des dilatations thermiques indésirables et limitent leurs performances.These known devices are however difficult to assemble and therefore of a high cost price. Furthermore, they have drawbacks such as poor evacuation of heat fluxes which can cause undesirable thermal expansion and limit their performance.

L'invention a pour objectif de fournir un disjoncteur dont le montage puisse être pratiquement entièrement automatisé, de façon à faire baisser considérablement son prix de revient.The object of the invention is to provide a circuit breaker, the assembly of which can be practically entirely automated, so as to considerably lower its cost price.

Un autre objectif de l'invention est de fournir un dis­joncteur dont la structure permet une utilisation optimale des volumes internes.Another object of the invention is to provide a circuit breaker whose structure allows optimal use of internal volumes.

Un autre objectif de l'invention est de fournir un tel appareil dont les parties sont agencées pour assurer la meilleure évacuation des flux thermiques en fonctionnement.Another objective of the invention is to provide such an apparatus, the parts of which are arranged to ensure the best evacuation of the thermal fluxes in operation.

Un autre objectif, encore, de l'invention est d'assurer une isolation électrique rigoureuse des circuits de phase et de neutre.Yet another objective of the invention is to ensure rigorous electrical isolation of the phase and neutral circuits.

Un autre objectif, encore, de l'invention est de mettre au point un procédé de fabrication et de montage pratique­ment entièrement automatisé, de cet appareil.Another objective, again, of the invention is to develop a manufacturing and assembly process which is practically entirely automated, of this device.

L'invention a pour objet un disjoncteur phase + neutre du type indiqué au début, disjoncteur qui comporte une pièce de structure centrale ayant une forme de cloison électriquement isolante définissant, de part et d'autre, un espace phase et un espace neutre, et pourvue de moyens de logement et/ou maintien de l'ensemble des pièces mécaniques et électriques de l'appareil, ainsi que deux pièces latérales, par exemple en forme de demi-coquille, suscepti­bles d'être fixées de part et d'autre de ladite pièce de structure pour délimiter lesdits espaces et refermer le volume interne de l'appareil, caractérisé en ce que ladite pièce de structure est agencée pour présenter, à proximité de la base, les espaces, logements et moyens de maintien recevant les moyens de disjonction mécanique et/ou thermi­que, les contrats mobiles de phase et de neutre et les circuits électriques phase et neutre avec leurs bornes respectives, et loin de la base, les espaces ou logements de cage d'extinction d'arc.The subject of the invention is a neutral phase + circuit breaker of the type indicated at the start, a circuit breaker which comprises a central structural part having the form of an electrically insulating partition defining, on both sides, a phase space and a neutral space, and provided with means for housing and / or holding all of the mechanical and electrical parts of the apparatus, as well as two lateral parts, for example in the form of a half-shell, capable of being fixed on either side of said structural part to delimit said spaces and close the internal volume of the apparatus, characterized in that said structural part is arranged to present, near the base, the spaces, housings and holding means receiving the disjunction means mechanical and / or thermal, the mobile phase and neutral contracts and the phase and neutral electrical circuits with their respective terminals, and far from the base, the spaces or housing of the cage arc extinction.

Dans une forme de réalisation préférée de l'invention, ladite pièce de structure est agencée pour pouvoir être prise en charge et déplacée de poste en poste, par des moy­ens de déplacement d'une machine de montage-transfert, et former ainsi la platine mobile sur laquelle, aux différents postes, cette machine présente et monte la majorité ou, de préférence, la totalité de tous les éléments et composants de l'appareil.In a preferred embodiment of the invention, said structural part is arranged to be able to be taken over and moved from station to station, by means of displacement of an assembly-transfer machine, and thus form the movable stage. on which, at the various stations, this machine presents and mounts the majority or, preferably, all of all the elements and components of the apparatus.

La cloison formée par la pièce de structure centrale peut être médiane pour diviser l'appareil en deux espaces sensiblement égaux ou au contraire décalée par rapport au plan médian. De préférence, elle présente un logement déporté vers l'une des pièces latérales, et venant de préférence jusqu'au contact de cette pièce pour recevoir l'ensemble de disjonction magnétique qui est toujours assez volumineux.The partition formed by the central structural part can be median to divide the device into two substantially equal spaces or, on the contrary, offset relative to the median plane. Preferably, it has a housing offset towards one of the lateral parts, and preferably coming into contact with this part to receive the magnetic disjunction assembly which is always quite bulky.

Conformément à l'invention, les moyens de disjonc­tion magnétique et/ou thermique, les contacts mobiles de phase et de neutre, et les circuits phase et neutre avec leurs bornes respectives, sont situés vers la base de l'ap­pareil qui comporte des moyens de fixation rapide sur un rail classique, le mécanisme ainsi que les chambres d'ex­tinction d'arc étant disposés en partie moyenne ou supérieu­re. On obtient ainsi un bon refroidissement par le rail contre lequel est fixée la base lorsque l'appareil est monté en position d'utilisation.According to the invention, the magnetic and / or thermal disjunction means, the movable phase and neutral contacts, and the phase and neutral circuits with their respective terminals, are located towards the base of the device which includes means for quick attachment to a conventional rail, the mechanism and the arc extinguishing chambers being arranged in the middle or upper part. Good cooling is thus obtained by the rail against which the base is fixed when the device is mounted in the use position.

Dans un mode de mise en oeuvre d'un procédé d'assemblage automatique selon l'invention, les éléments et composants de l'appareil, destinés à être montés sur ladite pièce de structure centrale faisant office de platine, sont groupés, avant le montage, en sous-ensembles et de préférence de la fa'on suivantes.In one embodiment of an automatic assembly method according to the invention, the elements and components of the apparatus, intended to be mounted on said central structural part acting as a plate, are grouped, before assembly , in sub-assemblies and preferably in the following ways.

On se réfère à l'ensemble des figures.We refer to all of the figures.

La pièce de structure centrale 1, moulée par injection, est vue du côté neutre sur la figure 1. Un fois que toutes les pièces et composants auront été montés, l'appareil se trouvera complété par l'assemblage, de part et d'autre de la pièce de structure 1, de la pièce latérale ou demi-coquille de phase 2 et de la pièce latérale ou demi-coquille de neu­tre 3.The central structural part 1, injection molded, is seen from the neutral side in FIG. 1. Once all the parts and components have been assembled, the apparatus will be completed by the assembly, on both sides. of the structural part 1, of the lateral part or half-shell of phase 2 and of the lateral part or half-shell of neutral 3.

La pièce de structure centrale comporte une cloison isolante médiane 4 munie à sa partie inférieure d'un ren­foncement 5 dont le fond peut être fermé ou présenter une ouverture 6, ledit fond étant destiné à venir s'appliquer contre la face interne de la demi-coquille 3. Du côté phase (voir figure 2), la structure 4 présente une cloison 8 sen­siblement parallèle à la base 9, en forme de semelle, de la pièce de structure 1. Le renfoncement forme ainsi un demi-­logement, complété, côté phase, par l'espace situé sous la cloison 8, logement recevant l'ensemble de disjonction magnétique contenu dans sa culasse, comme cela sera décrit par la suite.The central structural part comprises a central insulating partition 4 provided at its lower part with a recess 5, the bottom of which can be closed or have an opening 6, said bottom being intended to come to bear against the internal face of the half shell 3. On the phase side (see FIG. 2), the structure 4 has a partition 8 substantially parallel to the base 9, in the form of a sole, of the structural part 1. The recess thus forms a half-housing, completed, side phase, through the space located under the partition 8, housing receiving the magnetic circuit breaker assembly contained in its cylinder head, as will be described below.

De part et d'autre de la cloison 4 et au-dessus du logement ainsi défini, se trouvent des reliefs nervurés 10 destinés à assurer le positionnement des cages des chambres d'extinction d'arc.On either side of the partition 4 and above the housing thus defined, there are ribbed reliefs 10 intended to ensure the positioning of the cages of the arc extinguishing chambers.

Aux deux extrémités de la pièce de structure 1 se trouvent disposés des reliefs formant deux demi-logements 11, 12 de bornes neutre et deux demi-logements 13, 14 de bornes phase, les demi-logements 13, 14 étant surélevés par rapport aux demi-logements 11 et 12 de neutre. Ces demi-­logement seront ensuite complétés par des demi-logements correspondants 11a, 12a, 13a, 14a des demi-coquilles 2, 3 de sorte que les bornes se retrouveront emprisonnées dans les logements formés par la réunion des trois pièces 1, 2, 3.At the two ends of the structural part 1 are arranged reliefs forming two half-housings 11, 12 of neutral terminals and two half-housings 13, 14 of phase terminals, the half-housings 13, 14 being raised relative to the half - neutral housings 11 and 12. These half-housings will then be completed by corresponding half-housings 11a, 12a, 13a, 14a of the half-shells 2, 3 so that the terminals will find themselves trapped in the housings formed by the union of the three parts 1, 2, 3 .

A sa partie supérieure, à l'opposé de la base 9, la pièce de structure 1 présente une semelle 15 surmontée d'un ensemble 16 de deux fûts destinés à recevoir des vis ou rivets d'assemblage. Cette semelle 15 est interrompue à l'endroit où la cloison médiane 4 forme une échancrure arrondie 17 dans laquelle sera monté le porte-contacts. En direction de la base 9, à partir de l'échancrure 17, on trouve, de part et d'autre de la cloison 4, des cloisons descendantes 18, 19 délimitant entre elles deux passages allongés vers le bas. La partie supérieure de la cloison 19 présente, de part et d'autre de la cloison 4, de petits ren­foncements 20 sur lesquels viendront prendre appui les puis­sants ressorts de contact. Plus bas dans la cloison 4, se trouve un passage traversant 21 qui permettra la traversée d'un doigt de l'extrémité supérieure du levier déclencheur.At its upper part, opposite the base 9, the structural part 1 has a sole 15 surmounted by an assembly 16 of two barrels intended to receive assembly screws or rivets. This sole 15 is interrupted at the place where the central partition 4 forms a rounded notch 17 in which the contact carrier will be mounted. In the direction of the base 9, from the notch 17, there are, on either side of the partition 4, partitions descending 18, 19 delimiting between them two elongated downward passages. The upper part of the partition 19 has, on either side of the partition 4, small recesses 20 on which will come to bear the powerful contact springs. Lower in the partition 4, there is a through passage 21 which will allow the crossing of a finger from the upper end of the trigger lever.

A une certaine distance au-dessous du passage 21 se trouve une portée cylindrique 22 dans laquelle viendra s'encliqueter, à rotation libre, le pivot de rotation du levier déclencheur. Encore plus bas, la cloison 19 présente, du côté phase, une encoche 23 destinée à guider la tringle reliée à l'extrémité inférieure du levier déclencheur et susceptible d'être actionnée par l'extrémité de la bilame thermique.At a certain distance below the passage 21 is a cylindrical surface 22 into which will snap, free rotation, the pivot of the trigger lever. Even lower, the partition 19 has, on the phase side, a notch 23 intended to guide the rod connected to the lower end of the trigger lever and capable of being actuated by the end of the thermal bimetallic strip.

Entre la partie inférieure, située au-dessus de la base 9, des espaces phase et neutre et les logements de cage d'extinction d'arc, on voit que, du côté phase, la cloison 8 se termine par un renforcement arrondi 24 alors que le ren­foncement 5, du côté neutre, se termine au même niveau par un renforcement arrondi 25. Sur ces renforcements 24, 25, viendront se disposer les parties convenablement incurvées des contacts fixes de phase, respectivement de neutre. Ces renforcements 24, 25 sont situés à une certaine distance des cloisons 18 pour laisser un passage entre le haut et le bas, permettant le passage et le débattement des queues de con­tacts mobiles.Between the lower part, located above the base 9, phase and neutral spaces and the arc extinction cage housings, it can be seen that, on the phase side, the partition 8 ends in a rounded reinforcement 24 then that the recess 5, on the neutral side, ends at the same level with a rounded reinforcement 25. On these reinforcements 24, 25, the suitably curved parts of the fixed phase contacts, respectively neutral, will be disposed. These reinforcements 24, 25 are located at a certain distance from the partitions 18 to leave a passage between the top and the bottom, allowing the passage and movement of the tails of movable contacts.

Entre la cloison 19 et l'ensemble de demi-logements de borne 11, 13, se trouve disposé un logement allongé vertical 26 dont le fond présente une ouverture allongée 27, ledit fond venant, à l'assemblage, s'appliquer contre la face interne de la demi-coquille 3. Dans ce logement 26 sera reçue et pourra se débattre la bilame de disjonction ther­mique.Between the partition 19 and the set of terminal half-housings 11, 13, there is disposed an elongated vertical housing 26 whose bottom has an elongated opening 27, said bottom coming, during assembly, to be applied against the face internal of the half-shell 3. In this housing 26 will be received and may be struggling with the thermal disjunction bimetallic strip.

Les demi-coquilles 2 et 3 présentent, en correpondance des reliefs de la pièce de structure 1, des parois et nervures complémentaires, et notamment, outre des parois complémentaires pour former les logements de bornes précités, différentes nervures de maintien, telles que des nervures de maintien 10a de cage d'extinction d'arc, des cloisons périphériques telles que 28a venant compléter la base 9 et les cloisons périphériques 28 de la pièce de structure, et des cloisons internes complémentaires, notam­ment la cloison 8a venant compléter la cloison 8, et la cloison 19a venant compléter la cloison 19 du côté phase.The half-shells 2 and 3 have, in correspondence reliefs of the structural part 1, walls and complementary ribs, and in particular, in addition to complementary walls to form the aforementioned terminal housings, various retaining ribs, such as retaining ribs 10a of arc extinguishing cage, peripheral partitions such as 28a which complete the base 9 and the peripheral partitions 28 of the structural part, and additional internal partitions, in particular the partition 8a which completes the partition 8, and the partition 19a which completes the partition 19 on the phase side.

Par ailleurs, la demi-coquille 2 présente un pivot cylindrique 29 agencé pour recevoir, à pivotement, l'organe de manoeuvre et son ressort de rappel, ainsi qu'une large cloison supérieure 30 munie d'un passage supérieur 31 pour le passage de la manette de l'organe de manoeuvre.Furthermore, the half-shell 2 has a cylindrical pivot 29 arranged to receive, pivotally, the operating member and its return spring, as well as a large upper partition 30 provided with an upper passage 31 for the passage of the handle of the operating member.

Enfin, la pièce de structure 1 présente, outre l'ensemble de quatre fûts 16, un certain nombre de fûts disposés symétriquement de part et d'autre de la cloison 4, à savoir les fûts 32 à 35 contre lesquels viennent s'aligner des trous correspondant 32a à 35a des demi-coquilles 2, 3, par ailleurs pourvues de trous 16a en coïncidence avec les fûts 16, de façon à permettre le positionnement et l'assemblage des demi-coquilles sur la pièce de structure par vissage ou rivetage à travers les trous dans les fûts à l'aide de vis ou rivets d'assemblage. Le nombre de trous et de fûts est supérieur à celui qui serait strictement nécessaire pour l'assemblage de façon à permettre, le cas échéant, de superposer à l'appareil selon l'invention, un appareil auxiliaire quelconque tel que relais etc.Finally, the structural part 1 has, in addition to the set of four barrels 16, a number of barrels arranged symmetrically on either side of the partition 4, namely the barrels 32 to 35 against which are aligned corresponding holes 32a to 35a of the half-shells 2, 3, moreover provided with holes 16a in coincidence with the barrels 16, so as to allow the positioning and assembly of the half-shells on the structural part by screwing or riveting to through the holes in the barrels using assembly screws or rivets. The number of holes and barrels is greater than that which would be strictly necessary for assembly so as to allow, if necessary, to superimpose on the device according to the invention, any auxiliary device such as a relay etc.

Les éléments et composants de l'appareil vont main­tenant être décrits, ces éléments étant de préférence préalablement assemblés à l'état de sous-ensembles comme cela va être décrit :The elements and components of the apparatus will now be described, these elements preferably being assembled beforehand in the form of sub-assemblies as will be described:

Un sous-ensemble borne-bilame, côté phase, comporte la première borne phase 36, du type borne à cage usuelle, qui se poursuit, par exemple d'un seul tenant, par un prolonge­ment 37 orienté obliquement vers le haut et se poursuivant par une lame 38 dont le prolongement forme une tôle de con­duction 39 coiffant la cage d'extinction d'arc de phase 40. La branche 37 se poursuit, par un renvoi latéral convenable, par une patte sur laquelle est soudée la bilame thermique 41 dont la position peut être finement réglée par une vis de réglage 42 vissée dans une patte solidaire de la bilame et dont l'extrémité vient s'appliquer contre un renvoi de l'extrémité supérieure de la branche 37.A terminal-bimetal sub-assembly, on the phase side, comprises the first phase terminal 36, of the usual cage terminal type, which is continued, for example in one piece, by an extension 37 oriented obliquely upward and continuing by a blade 38, the extension of which forms a conduction sheet 39 covering the phase arc quenching cage 40. The branch 37 is continued, by a suitable lateral return, by a tab on which the thermal bimetal strip 41 is welded, the position can be finely adjusted by an adjustment screw 42 screwed into a lug secured to the bimetallic strip, the end of which comes to bear against a return from the upper end of the branch 37.

Un deuxième sous-ensemble de phase comporte une culasse ferro-magnétique 43 en forme de cage et intégrant, par un prolongement, la seconde borne de phase 44 avec sa cage usuelle, une bobine de disjonction 45 étant montée dans la culasse à laquelle elle est soudée par une première extrémité 46. La culasse présente, sur une face opposée à la borne, une échancrure partiellement circulaire 47 autour de laquelle est fixée, avec interposition d'un flasque isolant, une pièce découpée et pliée 48 formant le contact fixe 49 et se prolongeant à l'opposé par une électrode de commutation d'arc 50 venant se loger sous l'extrémité inférieure de la cage 40. Une patte 51 de la pièce 48, pénétrant dans l'échancrure 47, est électriquement reliée par soudage con­tre l'autre extrémité 52 de la bobine de disjonction 45. Celle-ci est montée, dans la culasse 43, autour d'une pièce isolante cylindrique 53 dans laquelle peut coulisser le noyau plongeur ferro-magnétique 54 auquel est fixée une tige 55 qui le prolonge et se termine par une tête élargie 56. Sur l'extrémité de la pièce cylindrique 53 vient de moulage le flasque isolant 57 ouvert au centre et venant s'interposer entre la face de la culasse 43 munie de l'échancrure partiellement circulaire 47 et la pièce conduc­trice de contact fixe 48 qui présente deux pattes orientées vers le bas et susceptibles de se loger dans des guides correspondants présentés par le flasque 57, ce dernier assurant ainsi l'isolation électrique entre la culasse et la pièce 48 et le maintien du contact fixe. Un ressort de rap­pel (non représenté) ramène le noyau 54, et donc la tige 55, à la position de repos éloignée du flasque 57.A second phase sub-assembly comprises a ferro-magnetic yoke 43 in the form of a cage and integrating, by an extension, the second phase terminal 44 with its usual cage, a disjunction coil 45 being mounted in the yoke to which it is welded by a first end 46. The cylinder head has, on a face opposite to the terminal, a partially circular notch 47 around which is fixed, with the interposition of an insulating flange, a cut and folded part 48 forming the fixed contact 49 and extending in opposite direction by an arc switching electrode 50 which is housed under the lower end of the cage 40. A tab 51 of the part 48, penetrating into the notch 47, is electrically connected by welding against the other end 52 of the disjunction coil 45. This is mounted, in the cylinder head 43, around a cylindrical insulating part 53 in which the ferromagnetic plunger core 54 auq can slide uel is fixed a rod 55 which extends it and ends with an enlarged head 56. On the end of the cylindrical part 53 comes from molding the insulating flange 57 open in the center and coming to be interposed between the face of the cylinder head 43 provided of the partially circular notch 47 and the conductive fixed contact piece 48 which has two legs oriented downwards and capable of being housed in corresponding guides presented by the flange 57, the latter thus ensuring electrical insulation between the cylinder head and the part 48 and the maintenance of the fixed contact. A return spring (not shown) returns the core 54, and therefore the rod 55, in the rest position far from the flange 57.

Un premier sous-ensemble de neutre comporte la première borne de neutre 58, avec sa cage usuelle, se poursuivant par un prolongement ascendant 59 et, après un renvoi, par un prolongement 60 aboutissant à une tôle de conduction 61 venant coiffer la cage d'extinction d'arc de neutre 62.A first neutral sub-assembly comprises the first neutral terminal 58, with its usual cage, continuing with an upward extension 59 and, after a return, by an extension 60 leading to a conduction sheet 61 coming to cap the cage. neutral arc extinction 62.

Un deuxième sous-ensemble de neutre comporte la deuxième borne de neutre 63, avec sa cage, qui présente, après un prolongement 64 en équerre, le contact fixe de neu­tre 65 se poursuivant par une tôle de conduction 66 venant se disposer sous la cage 62.A second neutral sub-assembly comprises the second neutral terminal 63, with its cage, which has, after an extension 64 at right angles, the fixed neutral contact 65 continuing with a conduction sheet 66 coming to be placed under the cage 62 .

Un sous-ensemble de mécanisme comporte un porte-contact 67 présentant deux pivots latéraux 68 portés par deux branches parallèles descendantes 69 laissant entre elles un espace à travers lequel s'étend une entretoise cylindrique 70, les deux branches étant réunies, à une certaine distance au-dessus de l'entretoise, par une tête aplatie 71 munie d'une lumière présentant une surface d'appui 73 inclinée destinée à coopérer avec l'une des extrémités d'une bielle 74 en forme de U, laquelle extrémité pénètre dans la lumière 72. Ce sous-ensemble comporte, outre le porte-contacts, un cliquet 75 pivoté par une échancrure centrale 76 sur l'entretoise 70 entre les branches 69 et présentant un bec d'accrochage 77 qui, convenablement incliné, empêche, avant la disjonction, la bielle 74 de s'échapper de la surface de poussée 73, ce cliquet 75 présentant une branche inférieure 78 destinée à être actionnée par le levier déclencheur. Un ressort circulaire 79, prenant appui d'une part dans un trou du cliquet et d'autre part sur un relief du porte-contacts, repousse faiblement le cliquet en position d'accrochage de l'extrémité de bielle. Ce sous-ensemble comporte encore le contact de phase 80 et le contact de neutre 81 qui présentent, comme on le voit bien sur les figures 8 et 9, un trou oblong 82 par lequel ils sont pivotés sur les pivots respectifs 68 du porte-contacts, un prolongement supérieur 83 reçu dans une concavité de la tête 71 du porte-contacts et, en position intermédiaire entre le trou oblong 82 et la partie 84 venant s'appliquer contre le contact fixe respec­tif, un trou rectangulaire 85, alors qu'une corne d'arc 86 se dirige vers la cage d'extinction d'arc respective 40, 62. A l'extrémité inférieure de la queue de contact est chaque fois soudée une tresse conductrice souple 87, respectivement 88.A subassembly of a mechanism comprises a contact carrier 67 having two lateral pivots 68 carried by two descending parallel branches 69 leaving between them a space through which extends a cylindrical spacer 70, the two branches being joined together at a certain distance above the spacer, by a flattened head 71 provided with a lumen having an inclined bearing surface 73 intended to cooperate with one of the ends of a U-shaped connecting rod 74, which end enters the light 72. This sub-assembly comprises, in addition to the contact carrier, a pawl 75 pivoted by a central notch 76 on the spacer 70 between the branches 69 and having a hooking spout 77 which, suitably inclined, prevents, before the disjunction, the connecting rod 74 to escape from the thrust surface 73, this pawl 75 having a lower branch 78 intended to be actuated by the trigger lever. A circular spring 79, bearing on the one hand in a hole of the pawl and on the other hand on a relief of the contact carrier, slightly pushes the pawl in the position for hooking the end of the connecting rod. This sub-assembly also includes the phase contact 80 and the neutral contact 81 which, as can be seen in FIGS. 8 and 9, have an oblong hole 82 by which they are pivoted on the respective pivots 68 of the contact carrier , an upper extension 83 received in a concavity of the head 71 of the contact carrier and, in the intermediate position between the oblong hole 82 and the part 84 which comes to bear against the respective fixed contact, a rectangular hole 85, while an arcing horn 86 moves towards the respective arc extinguishing cage 40, 62.

Le procédé de montage s'effectue de la façon suivante:The assembly process is carried out as follows:

Au départ, la pièce de structure 1, vide de tout con­stituant, est prise en charge par un moyen de transport d'une machine de montage-transfert.At the start, the structural part 1, empty of any constituent, is taken care of by a means of transport of an assembly-transfer machine.

A un premier poste de transfert, la machine vient met­tre en place, contre la paroi médiane 4 de la pièce 1, la tôle de blindage 107, puis la plaque isolante 108 puis la plaque 11, puis la cage d'extinction d'arc 40 reçue dans le même logement.
