Description

DOMAINE DE L'INVENTIONFIELD OF THE INVENTION

L'invention a trait aux appareils électriques comportant au moins une borne de connexion adaptée à recevoir de chaque côté un conducteur électrique (borne de connexion bilatérale).The invention relates to electrical devices comprising at least one connection terminal adapted to receive on each side an electrical conductor (bilateral connection terminal).

ARRIERE PLAN TECHNOLOGIQUEBACKGROUND TECHNOLOGY

On connaît déjà, notamment par la demande de brevet allemand 103 19 851 de tels appareils comportant un bornier muni de trois bornes de connexion bilatérale, chacune présentant une barrette rigide coopérant à chaque extrémité avec un ressort en σ.We already know, in particular by the German patent application 103 19 851 such devices comprising a terminal block provided with three bilateral connection terminals, each having a rigid strip cooperating at each end with a spring in σ.

La barrette forme un membre rigide présentant à chacune de ses extrémités un siège au niveau d'une ouverture d'insertion d'un conducteur électrique, chaque ressort ayant une arête en regard du siège correspondant.The bar forms a rigid member having at each of its ends a seat at an insertion opening of an electrical conductor, each spring having an edge facing the corresponding seat.

Chaque ressort est adapté, d'une part, à se déformer sous l'effet d'une sollicitation, grâce à quoi le conducteur, lorsqu'il est engagé dans la borne par l'ouverture d'insertion, peut s'insérer entre le siège et l'arête du ressort, et d'autre part, à retenir le conducteur entre le siège et l'arête sauf si il est déformé pour écarter l'arête du siège.Each spring is adapted, on the one hand, to deform under the effect of a bias, whereby the driver, when engaged in the terminal by the insertion opening, can be inserted between the seat and the edge of the spring, and secondly, to retain the driver between the seat and the ridge unless it is deformed to spread the edge of the seat.

L'appareil électrique comporte également, pour chaque ressort, un levier indépendant permettant de solliciter le ressort afin d'écarter son arête du siège du membre rigide.The electrical apparatus also comprises, for each spring, an independent lever for biasing the spring to move its edge of the seat of the rigid member.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

L'invention vise à fournir un appareil électrique du même genre, mais plus simple et commode à fabriquer, à assembler et à utiliser.The invention aims to provide an electrical appliance of the same kind, but more simple and convenient to manufacture, assemble and use.

Elle propose à cet effet un appareil électrique comportant une borne de connexion bilatérale, ladite borne présentant de chaque côté une ouverture d'insertion d'un conducteur électrique suivant une direction prédéterminée, un siège appartenant à un membre rigide et un membre flexible ayant une arête en regard dudit siège, ledit membre flexible étant adapté, d'une part, à se déformer sous l'effet d'une sollicitation grâce à quoi ledit conducteur, lorsqu'il est engagé dans ladite borne par ladite ouverture d'insertion, peut s'insérer entre ledit siège et ladite arête, et, d'autre part, à retenir le conducteur entre ledit siège et ladite arête sauf si il est déformé pour écarter ladite arête dudit siège, ledit appareil comportant également pour chaque membre flexible un levier pour écarter ladite arête dudit siège ; caractérisé en ce que chaque dit levier appartient à un organe d'actionnement monobloc comportant deux bras rigides en vis à vis formant chacun un dit levier, ledit organe d'actionnement comportant également une portion flexible reliant lesdits bras, ladite portion flexible étant adaptée à se déformer sous l'effet d'une sollicitation pour permettre à la distance entre lesdits bras de varier.It proposes for this purpose an electrical apparatus comprising a bilateral connection terminal, said terminal having on each side an insertion opening of an electrical conductor in a predetermined direction, a seat belonging to a rigid member and a flexible member having a ridge. opposite said seat, said flexible member being adapted, on the one hand, to deform under the effect of a bias whereby said conductor, when engaged in said terminal by said insertion opening, can inserting between said seat and said edge, and, secondly, retaining the conductor between said seat and said edge unless it is deformed to spread said edge of said seat, said apparatus also comprising for each flexible member a lever for spreading said edge of said seat; characterized in that each said lever belongs to a one-piece actuating member comprising two rigid arms facing each other, each forming a said lever, said actuating member also comprising a flexible portion connecting said arms, said flexible portion being adapted to deform under the effect of a bias to allow the distance between said arms to vary.

La réalisation d'un organe d'actionnement à deux leviers formé d'un seul bloc simplifie aussi bien la fabrication d'un tel appareil (puisqu'il permet de mouler les deux leviers d'une seule pièce) que l'assemblage (puisqu'il permet également de n'avoir à assembler qu'une seule pièce au lieu de deux).The realization of a two-lever actuator formed integrally simplifies both the manufacture of such an apparatus (since it allows to mold the two levers in one piece) that the assembly (since it also allows you to have to assemble only one piece instead of two).

De plus, et contrairement aux appareils électriques à bornes de connexion bilatérales tels que décrits notamment dans le modèle d'utilité allemand DE 76 13 091 U1 dans lequel l'organe d'actionnement est rigide est monté à basculement autour d'un unique point d'articulation, ne permettant d'agir qu'alternativement sur l'un ou l'autre des membres flexibles ; dans l'appareil électrique selon l'invention, la portion flexible de l'organe d'actionnement permet d'assurer une liaison mécanique permanente des leviers entre eux, tout en assurant un débattement de ces leviers indépendamment l'un de l'autre grâce à la capacité de la portion flexible à se déformer.In addition, unlike the electrical devices with bilateral connection terminals as described in particular in the German utility model DE 76 13 091 U1 wherein the actuating member is rigid is mounted to tilt about a single point of articulation, allowing to act alternatively on one or the other of the flexible members; in the electrical apparatus according to the invention, the flexible portion of the actuating member ensures a permanent mechanical connection of the levers between them, while ensuring a movement of these levers independently of one another through the ability of the flexible portion to deform.

Le bornier 3 illustré sur les figures 3 à 8 comporte un boîtier isolant 10, trois bornes de connexion bilatérales 11 et trois organes d'actionnement 12 (figure 6), chaque dite borne de connexion étant disposée dans le boîtier à côté d'un organe d'actionnement respectif (figures 7, 13 et 14).The terminal block 3 illustrated on the Figures 3 to 8 comprises an insulating housing 10, three bilateral connection terminals 11 and three actuating members 12 ( figure 6 ), each said connection terminal being disposed in the housing next to a respective actuating member ( figures 7 , 13 and 14 ).

Les prises 2 sont reliées électriquement au bornier 3 par l'intermédiaire des trois tiges conductrices 6 du bloc multiprises 1 (figures 3 et 4), les prises 2 présentant des moteurs de connexion (non représentés) encliquetés à ces tiges 6, chacune de ces tiges étant connectée par soudure à une borne de connexion bilatérale 11 du bornier.The sockets 2 are electrically connected to the terminal block 3 by means of the three conductive rods 6 of the power strip 1 ( Figures 3 and 4 ), the sockets 2 having connection motors (not shown) snapped to these rods 6, each of these rods being connected by welding to a bilateral connection terminal 11 of the terminal block.

Le boitier isolant 10 présente une embase 13 illustrée sur les figures 9 et 10 et un couvercle 14 illustré sur les figures 11 et 12 en plastique moulé isolant sur le plan électrique.The insulating housing 10 has a base 13 illustrated on the Figures 9 and 10 and a lid 14 shown on the Figures 11 and 12 of molded plastic insulating on the electrical plane.

L'embase 13 présente une section de forme globalement trapézoïdale (à l'exception des compartiments recevant les organes d'actionnement) et présente deux faces principales 15 et 16, deux faces latérales transversales 17 et 18 s'étendant de l'un à l'autre des petits côtés des faces principales et deux faces latérales longitudinales 19 et 20 (figure 4) inclinées l'une par rapport à l'autre s'étendant de l'un à l'autre des grands côtés des faces principales.The base 13 has a section of generally trapezoidal shape (with the exception of the compartments receiving the actuating members) and has two main faces 15 and 16, two transverse lateral faces 17 and 18 extending from one to the other. other of the short sides of the principal faces and two longitudinal lateral faces 19 and 20 ( figure 4 ) inclined relative to each other extending from one to the other of the long sides of the main faces.

L'embase 13 présente également, en outre des six faces susmentionnées, au niveau de chaque face latérale 17, 18, une patte d'encliquetage 25 en saillie vers l'extérieur de l'embase.The base 13 also has, in addition to the six aforementioned faces, at each side face 17, 18, a latching lug 25 projecting outwardly of the base.

La face principale 15 de l'embase présente une ouverture délimitée longitudinalement par deux bandeaux 21 dans chacun desquels sont ménagés trois trous 22, et, latéralement, par les bords des parois latérales de l'embase situées au niveau des faces 17 et 18.The main face 15 of the base has an opening delimited longitudinally by two strips 21 in each of which are arranged three holes 22, and laterally, by the edges of the side walls of the base located at the faces 17 and 18.

Cette embase comporte d'une part un logement 26 pour accueillir deux bornes de connexion l'une en face de l'autre, et, entre ses bornes, deux organes d'actionnement disposés côte à côte, et, d'autre part, un logement 27 pour accueillir côte à côte une troisième borne et un troisième organe d'actionnement.This base comprises, on the one hand, a housing 26 for accommodating two connection terminals facing each other, and, between its terminals, two actuating members arranged side by side, and, on the other hand, a housing 27 to accommodate side by side a third terminal and a third actuator.

Les logements 26 et 27 sont séparés par une cloison à double paroi 28 au centre de laquelle est ménagée une ouverture 29.The housings 26 and 27 are separated by a double wall partition 28 at the center of which is formed an opening 29.

A l'opposé de l'ouverture 29 par rapport au logement 26 est également ménagée dans la paroi latérale de l'embase située au niveau de la face 17 une ouverture 30 tandis qu'à l'opposé de l'ouverture 29 par rapport au logement 27 est ménagée dans la paroi latérale de l'embase située au niveau de la face 18 une ouverture 31.Opposite the opening 29 relative to the housing 26 is also formed in the side wall of the base located at the face 17 an opening 30 while opposite the opening 29 relative to the housing 27 is formed in the side wall of the base located at the face 18 an opening 31.

Le logement 26 comporte deux compartiments 35 et 36 de réception d'une borne de connexion respective, et entre ces compartiments, un compartiment 37 de réception des deux organes d'actionnement.The housing 26 has two compartments 35 and 36 for receiving a respective connection terminal, and between these compartments, a compartment 37 for receiving the two actuating members.

Chacun des compartiments 35 et 36 est séparé du compartiment 37 sur la moitié de sa hauteur par un muret 38.Each of the compartments 35 and 36 is separated from the compartment 37 on half of its height by a wall 38.

Le compartiment 35 (respectivement 36) débouche latéralement de l'embase par l'ouverture 30 (respectivement 29).The compartment 35 (respectively 36) emerges laterally from the base through the opening 30 (respectively 29).

Les compartiments 35 et 36 sont délimités entre autres par les surfaces internes des parois inclinées 40 et 41 de l'embase fermant les faces 19 et 20.The compartments 35 and 36 are delimited inter alia by the internal surfaces of the inclined walls 40 and 41 of the base closing the faces 19 and 20.

Dans le compartiment 37 sont disposées deux paires de nervures 46, chacune des paires de nervures étant disposée contre un muret 38 respectif, et deux nervures en T 47 à mi-distance des deux murets 38, avec les petites branches des nervures en T qui sont en regard l'une de l'autre, chaque nervure en T délimitant avec chacun des murets 38 et avec une nervure 46, une alvéole 45 adaptée à recevoir comme on le verra ci-après un tourillon d'articulation d'un organe d'actionnement.In the compartment 37 are arranged two pairs of ribs 46, each of the pairs of ribs being arranged against a respective wall 38, and two ribs T 47 halfway between the two walls 38, with the small branches of the ribs T which are facing each other, each rib T delimiting with each of the walls 38 and with a rib 46, a cell 45 adapted to receive as will be seen hereinafter a hinge pin of a body of actuation.

Au dessus de chaque alvéole 45 est formé au niveau des parois inclinées 40 et 41, une empreinte 48 adaptée à recevoir comme on le verra ci-après une portion d'un bras d'un organe d'actionnement.Above each cell 45 is formed at the inclined walls 40 and 41, a recess 48 adapted to receive as will be seen hereinafter a portion of an arm of an actuating member.

Le logement 27 comporte un compartiment 50 de réception d'une borne de connexion, et un compartiment 51 de réception d'un organe d'actionnement.The housing 27 comprises a compartment 50 for receiving a connection terminal, and a compartment 51 for receiving an actuating member.

Le compartiment 50 est séparé jusqu'à mi-hauteur du compartiment 51 par un muret 52 semblable aux murets 38 et débouche latéralement par l'ouverture 31.The compartment 50 is separated halfway up the compartment 51 by a wall 52 similar to the walls 38 and opens laterally through the opening 31.

Le compartiment 50 est également délimité par les surfaces internes de parois inclinées 40 et 41.The compartment 50 is also delimited by the internal surfaces of inclined walls 40 and 41.

Le compartiment 51 comporte deux alvéoles 53 chacune délimitée par une portion du muret 52, une nervure 54 (semblable aux nervures 46) disposée contre ce muret, une portion de la cloison 28 et une nervure 55 disposée contre cette cloison 28.The compartment 51 comprises two cells 53 each delimited by a portion of the wall 52, a rib 54 (similar to the ribs 46) disposed against this wall, a portion of the partition 28 and a rib 55 disposed against this partition 28.

Au dessus de chaque alvéole 53 est également ménagée une empreinte 48.Above each cell 53 is also formed an imprint 48.

Le couvercle 14 illustré sur les figures 11 et 12 coiffe l'embase 13 au niveau de sa face principale 15 et comporte un corps de couvercle 65 dans lequel sont ménagés un renfoncement longitudinal 66, et au voisinage de chacun des bords longitudinaux du corps 65, trois conduits d'introduction 60 de conducteurs électriques et trois ouvertures oblongues 61 adaptées à laisser passer comme on le verra ci-après les touches des organes d'actionnement.The lid 14 illustrated on the Figures 11 and 12 cap the base 13 at its main face 15 and comprises a cover body 65 in which are formed a longitudinal recess 66, and in the vicinity of each of the longitudinal edges of the body 65, three introduction conduits 60 of electrical conductors and three oblong openings 61 adapted to pass as will be seen below the keys of the actuating members.

Chaque conduit 60 présente une portion cylindrique 63 et une portion évasée 64.Each duct 60 has a cylindrical portion 63 and a flared portion 64.

Au voisinage d'un même bord longitudinal du couvercle sont disposées deux ouvertures 61 entre un conduit 60 situé au voisinage d'un des bords transversaux du couvercle et un conduit central 60 (à mi-distance des bords transversaux) tandis qu'entre le conduit central 60 et le conduit 60 situé au voisinage de l'autre bord transversal du couvercle est disposée une seule ouverture 61.In the vicinity of one and the same longitudinal edge of the lid are two openings 61 between a duct 60 located in the vicinity of one of the transverse edges of the lid and a central duct 60 (halfway between the transverse edges) while between the duct central 60 and the duct 60 located in the vicinity of the other transverse edge of the cover is arranged a single opening 61.

Du corps 65 du couvercle font également saillie du côté tourné vers l'intérieur de l'embase, au voisinage de chaque bord longitudinal, trois pions 62 (figure 12).Of the body 65 of the cover also protrude from the side facing the inside of the base, in the vicinity of each longitudinal edge, three pins 62 ( figure 12 ).

On va maintenant décrire une borne de connexion bilatérale 11 à l'aide des figures 15 à 20.We will now describe a bilateral connection terminal 11 using the Figures 15 to 20 .

Cette borne comporte une cage rigide 70 ainsi qu'un ressort en U 71.This terminal comprises a rigid cage 70 and a U-shaped spring 71.

La cage rigide 70 comporte deux gouttières 72, une paroi de liaison 73, un rebord 74 et un rebord 75.The rigid cage 70 comprises two gutters 72, a connecting wall 73, a flange 74 and a flange 75.

Chaque gouttière 72 présente une paroi de fond 76 et deux parois latérales 77 et 78, et à une extrémité une ouverture d'insertion 79 pour y introduire, comme on le verra ci-après, un conducteur électrique.Each channel 72 has a bottom wall 76 and two side walls 77 and 78, and at one end an insertion opening 79 to introduce, as will be seen hereinafter, an electrical conductor.

Les parois de fond 76 sont disposées à la façon des branches d'un V avec chaque paroi de fond 76 qui présente une surface 84 qui regarde l'autre paroi de fond 76 et qui forme, comme on le verra ci-après, un siège pour un conducteur électrique.The bottom walls 76 are arranged in the manner of the branches of a V with each bottom wall 76 which has a surface 84 which faces the other bottom wall 76 and which forms, as will be seen below, a seat for an electrical conductor.

Chaque paroi 78 est rattachée à la paroi de liaison 73 tandis que la paroi 77 présente à l'extrémité opposée de l'ouverture d'insertion 79 un repli 80 tourné vers la paroi 78.Each wall 78 is attached to the connecting wall 73 while the wall 77 has at the opposite end of the insertion opening 79 a fold 80 facing the wall 78.

Dans la paroi 77 est également ménagée une encoche 81, environ à mi-distance du repli 80 et de l'ouverture 79, permettant la mise en place du ressort 71 dans la cage 70 dans une position sous contrainte.In the wall 77 is also provided a notch 81, about midway between the fold 80 and the opening 79, allowing the introduction of the spring 71 in the cage 70 in a stressed position.

Le rebord 74 est plié transversalement à la paroi 73 du côté des gouttières 72 en étant rattaché au bord de la paroi 73 qui est situé au niveau des ouvertures 79 tandis que le rebord 75 est formée à partir d'une portion centrale de la paroi 73 découpée puis emboutie à la fabrication pour faire saillie transversalement par rapport à la paroi 73 du côté opposé aux gouttières 72.The flange 74 is folded transversely to the wall 73 of the gutter side 72 being attached to the edge of the wall 73 which is located at the openings 79 while the flange 75 is formed from a central portion of the wall 73 cut and then stamped to manufacture to protrude transversely relative to the wall 73 on the opposite side to the gutters 72.

Du rebord 74 font également saillie deux pattes 82 (figure 18) adaptées à être repliées sur elle-même pour serrer le ressort 71 contre ce rebord (figure 15).Edge 74 also project two legs 82 ( figure 18 ) adapted to be folded on itself to tighten the spring 71 against this flange ( figure 15 ).

On va maintenant décrire le ressort 71 à l'aide des figures 19 et 20.Spring 71 will now be described using the Figures 19 and 20 .

Ce ressort 71 est formé d'une bande en métal élastique allongée et repliée aux deux extrémités de sorte qu'elle présente une forme en U avec un tronçon central plat 90 raccordé à chaque extrémité à un tronçon incurvé 91, chaque tronçon incurvé 91 étant lui-même raccordé par l'extrémité opposée à celle raccordée au tronçon 90 à un tronçon incliné 92.This spring 71 is formed of an elongated elastic metal strip folded at both ends so that it has a U-shape with a flat central section 90 connected at each end to a curved section 91, each curved section 91 being - even connected by the end opposite to that connected to the section 90 to an inclined section 92.

Chaque tronçon 91 forme avec un tronçon incliné 92 un membre flexible 96 adapté à se déformer pour laisser passer un conducteur électrique.Each section 91 forms with an inclined portion 92 a flexible member 96 adapted to deform to pass an electrical conductor.

Chaque tronçon incliné 92 présente une oreille 93 et le tronçon central 90 présente deux pattes 94 en saillie latéralement par rapport au reste du ressort.Each inclined section 92 has an ear 93 and the central section 90 has two lugs 94 projecting laterally relative to the rest of the spring.

Chaque tronçon incliné 92 présente également une arête d'extrémité 95.Each inclined section 92 also has an end edge 95.

A l'état assemblé du ressort 71 dans la cage 70 (figures 15 à 17), le tronçon droit 90 du ressort 71 est pressé contre le rebord 74 par les pattes 82 alors repliées, avec les tronçons 91 et 92 qui sont tournés vers les gouttières 72, l'arête d'extrémité 95 de chaque tronçon 92 étant située en regard de la surface 84 d'une paroi de fond 76 correspondante, l'oreille 93 et les pattes 94 faisant saillie latéralement de la cage 70, l'oreille 93 faisant saillie par l'encoche 81.In the assembled state of the spring 71 in the cage 70 ( Figures 15 to 17 ), the right section 90 of the spring 71 is pressed against the flange 74 by the tabs 82 when folded, with the sections 91 and 92 which are turned to the gutters 72, the end edge 95 of each section 92 being located in view of the surface 84 of a corresponding bottom wall 76, the ear 93 and the lugs 94 projecting laterally from the cage 70, the lug 93 projecting through the notch 81.

On va maintenant décrire un organe d'actionnement à l'aide des figures 21 à 24.An actuator will now be described using the Figures 21 to 24 .

L'organe d'actionnement 12 est un organe moulé d'une seule pièce qui comporte deux bras rigides 100 en vis-à-vis reliés l'un à l'autre par une portion flexible 108.The actuating member 12 is a one-piece molded member which comprises two rigid arms 100 facing one another by a flexible portion 108.

La portion flexible 108 est constituée de deux compas 101 et 102.The flexible portion 108 consists of two compasses 101 and 102.

Chaque compas est formé d'une bande de la même matière que les bras 100 mais suffisamment mince pour pouvoir fléchir et se déformer lorsqu'elle est sollicitée, par exemple lorsque l'utilisateur agit sur l'un des deux bras 100.Each compass is formed of a band of the same material as the arms 100 but thin enough to be able to flex and deform when it is stressed, for example when the user acts on one of the two arms 100.

Chaque bras comporte un corps central 103, une touche 104, un tourillon d'articulation 105 et un téton 106.Each arm comprises a central body 103, a key 104, a pivot pin 105 and a pin 106.

La touche 104 est de forme globalement cylindrique arrondie à son extrémité libre et présente une empreinte 107 d'accueil de l'extrémité plate d'un tournevis pour faciliter si besoin l'actionnement du bras.The key 104 is generally cylindrical in shape rounded at its free end and has a footprint 107 of the flat end of a screwdriver to facilitate if necessary the actuation of the arm.

Le tourillon d'articulation 105 est un tronçon cylindrique rattaché transversalement au corps 103 à l'extrémité opposée de la touche 104.The hinge pin 105 is a cylindrical section attached transversely to the body 103 at the opposite end of the key 104.

Pour chaque bras, le téton 106 fait saillie latéralement et d'un seul côté du corps 103 à environ mi-distance du tourillon 105 et de la touche 104.For each arm, the pin 106 projects laterally and on one side of the body 103 about midway between the pin 105 and the key 104.

Le compas 101 se rattache à chacun des corps 103 au niveau de l'extrémité des corps où est disposée la touche 104 tandis que le compas 102 se rattache à chacun des corps 103 au niveau de l'extrémité des corps où est disposé le tourillon 105.The compass 101 is attached to each of the bodies 103 at the end of the body where is disposed the key 104 while the compass 102 is attached to each of the bodies 103 at the end of the body where is disposed the pin 105 .

On va maintenant décrire l'opération d'assemblage des bornes de connexion et des organes d'actionnement au sein du boitier isolant à l'aide des figures 6 à 8 et 13 et 14.We will now describe the assembly operation of the connection terminals and the actuating members within the insulating housing using the Figures 6 to 8 and 13 and 14 .

Dans un premier temps, on dispose dans chaque compartiment de réception 35 et 36 une borne de connexion 11, les oreilles 93 des ressorts 71 étant tournées vers le compartiment 37.At first, each receiving compartment 35 and 36 has a connection terminal 11, the ears 93 of the springs 71 being turned towards the compartment 37.

On dispose de la même façon dans le compartiment 50 une troisième borne de connexion, les oreilles 93 du ressort étant tournées vers le compartiment 51.In the same way, the compartment 50 has a third connection terminal, the ears 93 of the spring being turned towards the compartment 51.

On dispose ensuite dans le compartiment 37 de l'embase 13 deux organes d'actionnement côté à côte avec les tétons 106 des organes d'actionnement qui sont respectivement tournés vers les compartiments 35 et 36, chaque tourillon 105 venant se loger dans une alvéole 45 correspondante.In the compartment 37 of the base 13 there are then two actuating members side by side with the pins 106 of the actuating members which are respectively turned towards the compartments 35 and 36, each pin 105 being received in a cavity 45 corresponding.

On dispose de la même façon dans le compartiment 51 un troisième organe d'actionnement avec les tétons 106 de cet organe tournés vers le compartiment 50, chaque tourillon 105 venant se loger dans une alvéole 53.In the same way, the compartment 51 has a third actuating member with the pins 106 of this member facing towards the compartment 50, each pin 105 being received in a recess 53.

Les organes d'actionnement sont ainsi disposés à côté de leur borne de connexion respective avec les tétons 106 qui sont situés au voisinage des oreilles 93 des ressorts (figure 25).The actuating members are thus arranged next to their respective connection terminal with the pins 106 which are situated in the vicinity of the ears 93 of the springs ( figure 25 ).

Chaque cage 70 prend appui contre les deux parois inclinées 40 et 41 et contre deux parois latérales (soit un muret et une paroi latérale de l'embase, soit un muret et la cloison creuse 28) avec les rebords 75 des cages des bornes d'extrémité qui saillent de l'embase par les ouvertures 30 et 31 tandis que le rebord 75 de la cage de la borne intermédiaire traverse la cloison 28 par l'ouverture 29.Each cage 70 bears against the two inclined walls 40 and 41 and against two side walls (either a wall and a side wall of the base, or a wall and the hollow wall 28) with the flanges 75 of the cages of the terminals. end protruding from the base by the openings 30 and 31 while the rim 75 of the cage of the intermediate terminal through the partition 28 through the opening 29.

Ces rebords sont ainsi rendus accessibles pour venir y plaquer les tiges conductrices 6 (figures 3 et 4) pour les souder contre ces rebords.These edges are thus made accessible to come and press the conductive rods 6 ( Figures 3 and 4 ) to weld them against these edges.

On coiffe ensuite l'embase 13 du couvercle 14, les pions 62 traversant les ouvertures 22 et les touches 104 faisant alors saillie du couvercle par les ouvertures 61 (figure 5), chaque conduit 60 venant se placer en face d'une ouverture d'insertion 79 correspondante avec le côté de plus petit diamètre de la portion évasée 64 du conduit 60 qui est le plus près de l'ouverture d'insertion 79.The base 13 of the cover 14 is then capped, the pins 62 passing through the openings 22 and the keys 104 then projecting from the cover through the openings 61 (FIG. figure 5 ), each duct 60 being placed in front of a corresponding insertion opening 79 with the smaller diameter side of the flared portion 64 of the duct 60 which is closest to the insertion opening 79.

Les pions 62 sont alors écrasés par pression à température ambiante pour venir se refermer autour des ouvertures 22 permettant ainsi la réalisation d'un ensemble dans lequel l'embase et le couvercle sont solidaires.The pins 62 are then crushed by pressure at room temperature to be closed around the openings 22 thus allowing the realization of an assembly in which the base and the lid are integral.

Cet ensemble est ensuite encliqueté par les pattes d'encliquetage 25 aux fenêtres 5 de l'enveloppe isolante 4 de l'appareil électrique 1, un bandeau 7 de cette enveloppe (figure 1) venant se loger dans le renfoncement longitudinal 66 du corps 65 de façon à maintenir en position le couvercle 14 contre l'embase 13.This assembly is then latched by the latching tabs 25 to the windows 5 of the insulating envelope 4 of the electrical apparatus 1, a strip 7 of this envelope ( figure 1 ) being housed in the longitudinal recess 66 of the body 65 so as to hold the cover 14 in position against the base 13.

On va maintenant expliquer à l'aide des figures 25 à 30 comment mettre en place de chaque côté d'une borne à connexion bilatérale un conducteur électrique et plus précisément l'extrémité dénudée de celui-ci, ce conducteur étant du type rigide.We will now explain with the help of Figures 25 to 30 how to set up on each side of a bilateral connection terminal an electrical conductor and more precisely the stripped end thereof, the conductor being rigid type.

L'extrémité dénudée 111 d'un conducteur 110 (comme illustré en figures 25 à 30 avec deux conducteurs électriques, chacun inséré d'un côté d'une borne 11) est introduite dans l'appareil électrique par l'un des conduits 60 (figure 5), la portion évasée 64 de ce conduit ayant pour effet de guider l'extrémité dénudée vers l'une des ouvertures d'insertion 79 de la borne de connexion.The stripped end 111 of a conductor 110 (as illustrated in FIG. Figures 25 to 30 with two electrical conductors, each inserted on one side of a terminal 11) is introduced into the electrical apparatus through one of the conduits 60 ( figure 5 ), the flared portion 64 of this conduit having the effect of guiding the stripped end towards one of the insertion openings 79 of the connection terminal.

Au cours de l'insertion, l'extrémité dénudée 111 rencontre le tronçon incliné 92 et entraîne à fléchir le membre flexible 96 de sorte qu'il laisse l'extrémité du conducteur s'insérer, entre l'arête d'extrémité 95 du tronçon 92, et la paroi de fond 76 (figure 29).During the insertion, the stripped end 111 encounters the inclined section 92 and causes the flexible member 96 to flex so that the end of the conductor is inserted between the end edge 95 of the stub 92, and the bottom wall 76 ( figure 29 ).

La surface interne 84 de la paroi de fond 76 forme pour le conducteur un siège contre lequel il est maintenu par ce tronçon qui le plaque contre la surface 84.The inner surface 84 of the bottom wall 76 forms for the driver a seat against which it is held by this section which plates it against the surface 84.

Si le conducteur une fois installé dans cette borne tend à être retiré du boitier, c'est-à-dire s'il est soumis à un effort dirigé dans un sens contraire au sens d'insertion, ce conducteur aura tendance à entraîner avec lui le tronçon incliné 92 de sorte que ce tronçon 92 et le tronçon incurvé 91 auquel il est raccordé vont s'arcbouter et coincer le conducteur contre la surface 84, ce qui interdira son retrait.If the driver once installed in this terminal tends to be removed from the housing, that is to say if it is subjected to a force directed in a direction contrary to the direction of insertion, the driver will tend to train with him the inclined section 92 so that this section 92 and the curved section 91 to which it is connected will buckle and jam the driver against the surface 84, which will prohibit its withdrawal.

Il est néanmoins possible de procéder au retrait du conducteur grâce au bras correspondant 100 de l'organe d'actionnement 12. Pour cela l'opérateur agit sur le bras comme sur un levier afin de le faire passer d'une position relevée (figure 26), une portion 115 du corps 103 du bras étant alors disposée dans l'empreinte 48 correspondante du boîtier, à une position rabattue comme illustrée en figure 28 (sur cette figure, les deux bras sont représentés dans leur position rabattue).It is nevertheless possible to remove the driver through the corresponding arm 100 of the actuating member 12. For this the operator acts on the arm as on a lever to move it from a raised position ( figure 26 ), a portion 115 of the body 103 of the arm then being disposed in the corresponding recess 48 of the housing, in a folded position as illustrated in FIG. figure 28 (In this figure, the two arms are shown in their folded position).

Lorsque l'opérateur agit simultanément sur les deux bras (en pressant simultanément les touches 104 des deux bras 100 l'une vers l'autre par exemple en les saisissant entre le pouce et l'index), chacun des bras est entraîné sous l'action de l'opérateur à pivoter pour se rapprocher de l'autre bras, les tourillons d'articulation 105 des bras étant maintenus en position dans les alvéoles correspondantes (45 ou 53) de l'embase, avec les compas 101 et 102 (figures 24 et 28) qui se déforment, les branches de chaque compas se rapprochant l'une de l'autre.When the operator acts simultaneously on the two arms (by simultaneously pressing the keys 104 of the two arms 100 towards each other for example by grasping them between the thumb and forefinger), each arm is driven under the action of the operator to rotate to get closer to the other arm, the pivot pins 105 of the arms being held in position in the corresponding cells (45 or 53) of the base, with the compasses 101 and 102 ( figures 24 and 28 ) that deform, the branches of each compass coming closer to each other.

Au cours du pivotement les tétons 106 des bras 100 prennent appui contre les oreilles 93 des membres flexibles 96 pour ainsi écarter simultanément les arêtes d'extrémité 95 des tronçons droits 92 de leur siège respectif 84 (figures 27, 28 et 30) grâce à quoi un des deux conducteurs ou bien les deux conducteurs peuvent être retirés de la borne dans laquelle ils ont été engagés (figures 28 et 30).During the pivoting, the pins 106 of the arms 100 bear against the ears 93 of the flexible members 96, thus simultaneously moving the end edges 95 of the straight sections 92 from their respective seats 84 (FIG. figures 27 , 28 and 30 ) whereby one of the two conductors or the two conductors may be removed from the terminal in which they were engaged ( figures 28 and 30 ).

Une fois le ou les conducteurs retirés, les bras 100 reviennent automatiquement dans leur position initiale par rappel élastique des membres 96 et des compas 101 et 102.Once the conductor (s) removed, the arms 100 automatically return to their initial position by elastic return of the members 96 and the compass 101 and 102.

Bien entendu, il est également possible de n'agir que sur un seul des deux bras 100 par exemple si l'on ne souhaite déconnecter qu'un seul conducteur.Of course, it is also possible to act on only one of the two arms 100 for example if one wishes to disconnect only one driver.

Pour cela, l'opérateur agit sur le bras concerné en exerçant une force orientée en direction de l'autre bras de façon à permettre au bras sollicité de pivoter autour de son tourillon 105 en direction du bras opposé.For this, the operator acts on the arm concerned by exerting a force directed towards the other arm so as to allow the arm urged to pivot about its pin 105 in the direction of the opposite arm.

On notera qu'il est également possible, pour faciliter le raccordement à la borne d'un conducteur souple, d'engager l'extrémité de celui-ci dans l'une des ouvertures de cette borne en même temps qu'on agit sur le bras 100 correspondant afin d'écarter l'arête d'extrémité 95 du tronçon incliné 92 du siège 84 pour permettre à l'extrémité dénudée de se placer entre eux.Note that it is also possible, to facilitate the connection to the terminal of a flexible conductor, to engage the end thereof in one of the openings of this terminal at the same time it acts on the corresponding arm 100 to separate the end edge 95 of the inclined portion 92 of the seat 84 to allow the stripped end to be placed between them.

Un des avantages de cet agencement est que l'action du bras en direction du bras opposé permet au cours de son pivotement de rendre plus accessible le conduit 60 puisque les doigts de l'opérateur s'éloignent de ce conduit au cours de ce pivotement.One of the advantages of this arrangement is that the action of the arm towards the opposite arm allows during its pivoting to make the duct 60 more accessible since the operator's fingers move away from this duct during this pivoting.

Un tel agencement permet également d'arranger les conducteurs raccordés de façon optimale, puisqu'il tire profit des deux côtés du bornier pour placer les câbles harmonieusement au sein de l'appareil électrique (gestion du « mou » des câbles améliorée).Such an arrangement also makes it possible to arrange the connected conductors optimally, since it takes advantage of both sides of the terminal block to place the cables harmoniously within the electrical device (management of "slack" cables improved).

De plus la force de rappel élastique grâce au membre flexible ainsi que la présence de conducteurs électriques au voisinage et de chaque côté des leviers assurent une protection supplémentaire contre les risques de manoeuvre intempestive de ces leviers.In addition the elastic restoring force thanks to the flexible member as well as the presence of electrical conductors in the vicinity and on each side of the levers provide additional protection against the risk of inadvertent operation of these levers.

Un autre mode de réalisation est représenté en figure 31.Another embodiment is shown in figure 31 .

D'une manière générale, on a employé pour les éléments similaires les mêmes références, en y ajoutant le caractère '.In general, the same references have been used for similar elements, adding the character '.

Dans ce mode de réalisation, l'appareil électrique comporte une ou plusieurs bornes de connexion 11' chacune comportant une barrette rigide 70' et deux ressort en σ 71' distincts.In this embodiment, the electrical apparatus comprises one or more connection terminals 11 'each having a rigid strip 70' and two separate spring σ 71 '.

La barrette 70' présente un tronçon droit de liaison 74' et deux tronçons inclinés 76' par rapport au tronçon droit, chaque tronçon 76' présentant à son extrémité une portion étroite dans laquelle est engagé un ressort en σ 71' par l'intermédiaire d'une ouverture d'insertion 79'.The bar 70 'has a right connecting section 74' and two inclined sections 76 'with respect to the straight section, each section 76' having at its end a narrow portion in which is engaged a spring in σ 71 'via an insertion opening 79 '.

Chaque ressort en σ 71' comporte un premier tronçon 90' relativement rectiligne présentant à une extrémité une languette étroite 97', un deuxième tronçon relativement rectiligne 92' disposé transversalement par rapport au tronçon 90', présentant une fenêtre centrale 79' de même largeur que la languette 97' et dans laquelle cette languette est engagée, ainsi qu'un troisième tronçon 91' incurvé aux deux extrémités, relié par une première extrémité à l'extrémité proximale du tronçon 90' et par une seconde extrémité à l'extrémité proximale du tronçon 92'.Each spring at σ 71 'comprises a first relatively straight section 90' having at one end a narrow tongue 97 ', a second relatively straight section 92' disposed transversely with respect to section 90 ', having a central window 79' of the same width as the tongue 97 'and in which this tongue is engaged, and a third section 91' curved at both ends, connected by a first end to the proximal end of the section 90 'and a second end to the proximal end of the section 90'; section 92 '.

En l'absence de sollicitation, la portion d'extrémité du tronçon droit 76' de la barrette de même largeur que la languette 97' est serrée entre la languette 97' et l'arête 95' du tronçon 92'.In the absence of stress, the end portion of the right section 76 'of the bar of the same width as the tongue 97' is clamped between the tongue 97 'and the edge 95' of the section 92 '.

Les tronçons 91' et 92' forment un membre flexible 96' qu'il est possible de déformer à l'aide d'un organe d'actionnement 12' pour écarter l'arête 95' du siège 84'.The sections 91 'and 92' form a flexible member 96 'which can be deformed by means of an actuating member 12' to move the edge 95 'away from the seat 84'.

L'organe d'actionnement 12' est disposé entre les ressorts en σ 71'.The actuating member 12 'is disposed between the springs at σ 71'.

Cet organe comporte deux bras rigides en vis-à-vis 100' et une portion flexible 108' comportant deux compas 101' et 102'.This member comprises two rigid arms vis-à-vis 100 'and a flexible portion 108' comprising two compasses 101 'and 102'.

Chaque bras présente un corps 103', une touche 104' disposée à une extrémité du corps, un doigt 106' disposé à l'autre extrémité du corps et un tourillon d'articulation 105' entre la touche 104' et le doigt 106', le tourillon comportant de chaque côté un pion 109' en saillie latéralement par rapport au corps 103'. Chaque pion 109' étant engagé dans un logement du boîtier isolant (dont seule une paroi 32' est représentée en figure 31). Le compas 101' relie les bras 100' au niveau des touches 104' tandis que le compas 102' relie les bras 100' globalement au niveau des doigts 106'.Each arm has a body 103 ', a key 104' disposed at one end of the body, a finger 106 'disposed at the other end of the body and a pivot pin 105' between the key 104 'and the finger 106', the pin having on each side a pin 109 'projecting laterally relative to the body 103'. Each pin 109 'being engaged in a housing of the insulating housing (of which only one wall 32 'is represented in figure 31 ). The compass 101 'connects the arms 100' at the keys 104 'while the compass 102' connects the arms 100 'generally at the fingers 106'.

Lors d'une action sur un bras 100' par l'intermédiaire de la touche 104', celui-ci est entraîné à pivoter autour du tourillon 105' de sorte que les compas 101' et 102' se déforment avec les deux branches du compas 101' qui se rapprochent l'une de l'autre et les deux branches du compas 102' qui s'éloignent l'une de l'autre, le doigt 106' du bras venant déformer le membre flexible 96' du ressort 71' correspondant pour écarter l'arête 95' du siège 84' afin de permettre soit d'insérer soit de retirer un conducteur électrique 110.When an action on an arm 100 'via the key 104', it is rotated around the pin 105 'so that the compass 101' and 102 'deform with the two arms of the compass 101 'which approach one another and the two arms of the compass 102' which move away from each other, the finger 106 'of the arm deforming the flexible member 96' of the corresponding spring 71 ' to remove the edge 95 'of the seat 84' to allow either to insert or remove an electrical conductor 110.
