Description

DOMAINE DE L'INVENTIONFIELD OF THE INVENTION

La présente invention concerne les prises électriques et plus particulièrement les prises de courant.The present invention relates to electrical outlets and more particularly the outlets.

ARRIÈRE-PLAN TECHNOLOGIQUETECHNOLOGICAL BACKGROUND

On connaît déjà des prises électriques comportant un boîtier isolant, au moins une alvéole d'accueil pour une broche d'une fiche à raccorder à la prise et au moins une borne à connexion automatique pour relier l'alvéole à au moins un câble d'alimentation, la borne présentant une ouverture d'insertion du câble suivant une direction prédéterminée ainsi qu'un siège et un membre flexible.Electrical outlets having an insulating housing, at least one receiving cavity for a pin of a plug to be connected to the socket and at least one automatically connected terminal for connecting the cell to at least one cable are already known. power supply, the terminal having a cable insertion opening in a predetermined direction as well as a seat and a flexible member.

Le membre flexible présente une arête en regard du siège et est adapté, d'une part, à se déformer sous l'effet d'une sollicitation orientée suivant la direction prédéterminée dans un sens d'insertion grâce à quoi le câble, lorsqu'il est engagé dans la borne par l'ouverture d'insertion, peut s'insérer entre le siège et l'arête, et, d'autre part, à retenir le câble entre le siège et l'arête sous l'effet d'une sollicitation orientée suivant la direction prédéterminée dans un sens d'extraction opposé au sens d'insertion sauf si le membre flexible est déformé pour écarter l'arête du siège.The flexible member has an edge facing the seat and is adapted, on the one hand, to deform under the effect of a bias oriented along the predetermined direction in a direction of insertion whereby the cable, when is engaged in the terminal by the insertion opening, can be inserted between the seat and the edge, and, secondly, to retain the cable between the seat and the edge under the effect of a urging oriented in the predetermined direction in an extraction direction opposite to the direction of insertion unless the flexible member is deformed to move the edge of the seat.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

L'invention vise à fournir une prise électrique à la fois simple et facile à raccorder à un câble tout en étant performante et fiable.The invention aims to provide an electrical outlet both simple and easy to connect to a cable while being powerful and reliable.

Elle propose à cet effet une prise électrique comportant un boîtier isolant, au moins une alvéole d'accueil pour une broche prédéterminée et au moins une borne à connexion automatique pour relier ladite alvéole à au moins un câble d'alimentation, ladite borne présentant une ouverture d'insertion dudit câble suivant une direction prédéterminée ainsi qu'un siège et un membre flexible, ledit membre flexible ayant une arête en regard dudit siège et étant adapté, d'une part, à se déformer sous l'effet d'une sollicitation orientée suivant ladite direction dans un sens d'insertion grâce à quoi ledit câble, 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 câble entre ledit siège et ladite arête sous l'effet d'une sollicitation orientée suivant ladite direction dans un sens d'extraction opposé au sens d'insertion sauf si ledit membre flexible est déformé pour écarter ladite arête dudit siège, caractérisée en ce que ladite borne comporte un membre d'appui auquel appartient ledit siège et un membre fixe qui porte ledit membre flexible, ledit membre d'appui étant mobile par rapport audit membre fixe de cette borne, et en ce que ladite alvéole présente un membre fixe et un membre mobile par rapport audit membre fixe de cette alvéole, ladite alvéole étant adaptée à ce que ledit membre mobile de cette alvéole subisse un déplacement par rapport audit membre fixe de cette alvéole lors de l'introduction de ladite broche dans l'alvéole, ladite prise comportant également un membre de liaison du membre mobile de l'alvéole au membre d'appui de la borne adapté à entraîner ledit membre d'appui vers ledit membre flexible lors dudit déplacement grâce à quoi le câble est d'avantage enserré par ledit membre d'appui et ledit membre flexible en présence de ladite broche dans ladite alvéole.It proposes for this purpose an electrical socket comprising an insulating housing, at least one receiving cavity for a predetermined pin and at least one automatically connected terminal for connecting said cell to at least one power cable, said terminal having an opening insertion of said cable in a predetermined direction and a seat and a flexible member, said flexible member having an edge facing said seat and being adapted, on the one hand, to deform under the effect of a biased stress along said direction in an insertion direction whereby said cable, when engaged in said terminal by said insertion opening, is insertable between said seat and said edge, and, on the other hand, retains the cable between said seat and said edge under the effect of a bias oriented along said direction in an extraction direction opposite to the direction insertion device unless said flexible member is deformed to move said edge away from said seat, characterized in that said terminal comprises a support member to which said seat belongs and a fixed member which carries said flexible member, said support member being movable relative to said fixed member of this terminal, and in that said cell has a fixed member and a member movable relative to said fixed member of said cell, said cell being adapted so that said movable member of said cell undergoes relative displacement. to said fixed member of this cell during the introduction of said pin into the cell, said plug also comprising a connecting member of the movable member of the cell to the support member of the terminal adapted to drive said support member towards said flexible member during said movement whereby the cable is further gripped by said support member and said flexible member in the presence of said pin da ns said cell.

Lors de l'introduction d'une broche dans la prise, l'entraînement du membre d'appui de la borne par le membre mobile de l'alvéole fait passer le membre d'appui d'une première position qu'il occupe en l'absence de la broche à une seconde position qu'il occupe en présence de la broche.When introducing a pin into the socket, the drive of the support member of the terminal by the movable member of the cell passes the support member of a first position it occupies in the absence of the spindle at a second position that it occupies in the presence of the spindle.

Dans la première position du membre d'appui, le membre flexible n'est pas ou peu contraint par le membre d'appui de sorte qu'il est possible d'introduire un câble entre le membre d'appui et le membre flexible sans avoir à fournir des efforts excessifs tandis que dans la seconde position le membre d'appui engendre par l'intermédiaire du câble un fléchissement supplémentaire du membre flexible qui garantit, uniquement lorsque cela est nécessaire (c'est-à-dire lorsque le câble est raccordé à la borne), un excellent contact électrique en renforçant la pression de contact du câble au membre d'appui et au membre flexible.In the first position of the support member, the flexible member is not or only slightly constrained by the support member so that it is possible to introduce a cable between the support member and the flexible member without having to provide excessive forces while in the second position the support member generates through the cable further deflection of the flexible member which ensures, only when necessary (ie when the cable is connected at the terminal), an excellent electrical contact by reinforcing the contact pressure of the cable to the support member and the flexible member.

A l'inverse, lorsque la broche est extraite de l'alvéole le membre d'appui est libéré de sorte que la pression d'enserrement redevient sensiblement celle qui était présente lors de l'introduction du câble ce qui permet d'actionner facilement le membre flexible pour en extraire le câble.Conversely, when the pin is extracted from the cell the support member is released so that the squeeze pressure becomes substantially that which was present during the introduction of the cable which allows to easily operate the flexible member to extract the cable.

On notera qu'il était certes connu de prévoir dans une prise de courant une alvéole déformable pour assurer le contact avec la broche et même pour entraîner un contact mobile vers un contact fixe, par exemple pour des prises de courant à coupure interne (voir notamment la demande de brevet français 2 784 511 ), mais dans la prise selon l'invention l'alvéole présente la particularité d'avoir un membre fixe et un membre mobile, le membre mobile étant lié mécaniquement non pas à un contact mobile mais à une borne de raccordement d'un câble d'alimentation de la prise, ce câble une fois introduit dans la borne restant en contact électrique permanent avec cette borne et cette alvéole, qu'une broche soit présente ou non dans l'alvéole.Note that it was certainly known to provide in a socket a deformable cell to ensure contact with the pin and even to cause a movable contact to a fixed contact, for example for plugs with internal cut (see in particular the patent application French 2,784,511 ), but in the socket according to the invention the cell has the particularity of having a fixed member and a movable member, the movable member being mechanically connected not to a movable contact but to a connection terminal of a cable d supply of the plug, this cable once introduced into the terminal remaining in permanent electrical contact with this terminal and this cell, a pin is present or not in the cell.

DESCRIPTION DÉTAILLÉE D'UN EXEMPLE DE RÉALISATION PRÉFÉRÉDETAILED DESCRIPTION OF AN EXEMPLARY PREFERRED EMBODIMENT

La prise de courant 1 illustrée sur les figures 1 à 3 comporte un boîtier isolant 2 en matière plastique, un capot 3 du même matériau ainsi que trois modules de raccordement 4 (figure 3).The socket 1 illustrated in Figures 1 to 3 comprises an insulating housing 2 of plastic, a cover 3 of the same material and three connection modules 4 (Figure 3).

Chaque module de raccordement 4 est adapté à recevoir d'un côté un câble électrique 5 et de l'autre la broche correspondante 6 d'une fiche 7 (figure 13).Each connection module 4 is adapted to receive on one side an electric cable 5 and the other the corresponding pin 6 of a plug 7 (Figure 13).

Le boîtier isolant 2 présente un premier compartiment 10 et un second compartiment 11.The insulating housing 2 has a first compartment 10 and a second compartment 11.

Chacun des compartiments présente une forme globalement parallélépipédique avec le compartiment 10 qui est plus petit et accolé contre une des faces du compartiment 11, centré par rapport à cette face. Le premier compartiment communique avec le second par l'intermédiaire de trois fenêtres rectangulaires 13 (figure 3).Each of the compartments has a generally parallelepipedal shape with the compartment 10 which is smaller and attached to one of the faces of the compartment 11, centered with respect to this face. The first compartment communicates with the second through three rectangular windows 13 (Figure 3).

De part et d'autre des fenêtres 13 sont disposées dans le compartiment 11 des cloisons de séparation 15 qui se prolongent dans le compartiment 10 de sorte qu'elles délimitent avec les compartiments 10 et 11 trois logements distincts d'accueil des modules de raccordement 4.On both sides of the windows 13 are arranged in the compartment 11 of partition walls 15 which extend into the compartment 10 so that they delimit with the compartments 10 and 11 three separate housing receiving docking modules 4 .

Dans la paroi du compartiment 10 située au niveau de la face de ce compartiment opposée à celle raccordée au compartiment 11, sont ménagés pour chaque module de raccordement deux conduits d'insertion 18 de câbles électriques ainsi qu'un orifice 19 de passage d'un bouton poussoir que comporte chacun des modules de raccordement.In the wall of the compartment 10 situated at the level of the face of this compartment opposite to that connected to the compartment 11, there are provided for each connection module two insertion ducts 18 of electric cables and an orifice 19 for the passage of a push button that includes each of the connection modules.

Le compartiment 11 est entièrement ouvert au niveau de sa face opposée à celle raccordée au compartiment 10 si ce n'est à sa périphérie où l'ouverture est entourée d'une collerette à contour rectangulaire 20 adaptée à coopérer par sa forme avec le capot d'obturation 3.The compartment 11 is fully open at its opposite side to that connected to the compartment 10 except on its periphery where the opening is surrounded by a flange with a rectangular contour 20 adapted to cooperate by its shape with the shutter cover 3.

Ce capot 3 présente trois orifices de passage 25 ménagés dans une paroi 26 en renfoncement par rapport au reste du capot ainsi qu'une nervure de détrompage 27. Le renfoncement du capot présente un contour adapté à recevoir par coopération de forme la portion d'une fiche 7 correspondante.This cover 3 has three through holes 25 formed in a recessed wall 26 relative to the remainder of the cover and a polarizing rib 27. The recess of the cover has a contour adapted to receive by cooperation of shape the portion of a corresponding card 7.

La fiche 7 illustrée en figure 4 comporte un boîtier isolant 30, trois broches 6 saillant du boîtier 30 ainsi qu'un collier 31.The plug 7 illustrated in FIG. 4 comprises an insulating housing 30, three pins 6 projecting from the housing 30 and a collar 31.

Chacune des broches 6 est raccordée à un conducteur électrique (non représenté) sortant du boîtier isolant 30 au travers du collier 31.Each of the pins 6 is connected to an electrical conductor (not shown) coming out of the insulating housing 30 through the collar 31.

On va maintenant décrire les modules de raccordement 4 à l'aide des figures 6 à 14.The connection modules 4 will now be described using FIGS. 6 to 14.

Chaque module de raccordement 4 comporte un bâti rigide et fixe 40, un bras mobile 41, une lame ressort flexible 42, ainsi qu'un bouton poussoir d'actionnement 43 (figure 8).Each connection module 4 comprises a rigid and fixed frame 40, a movable arm 41, a flexible spring blade 42, and an actuating push button 43 (FIG. 8).

Le bâti 40 comporte une cage 45 à section rectangulaire ainsi qu'une paroi 46. La paroi 46 se situe dans le prolongement d'une paroi 47 de la cage 45 opposée à une paroi 49 de cette cage portant la lame ressort 42 (figure 11).The frame 40 comprises a cage 45 with a rectangular section and a wall 46. The wall 46 is located in the extension of a wall 47 of the cage 45 opposite a wall 49 of this cage carrying the leaf spring 42 (FIG. ).

Dans la cage 45 sont formées deux pattes 44 tandis que la paroi 46 présente deux ailettes 48.In the cage 45 are formed two tabs 44 while the wall 46 has two fins 48.

La cage 45 délimite avec le poussoir 43 deux ouvertures 39 d'insertion de câbles électriques.The cage 45 defines with the pusher 43 two openings 39 for insertion of electric cables.

Le bras 41 présente une première paroi 50 (figure 11) dont une extrémité est raccordée à la paroi 47 par un repli en U 53 élastiquement déformable, une deuxième paroi 51 dont une extrémité se raccorde transversalement à l'extrémité de la paroi 50 opposée à celle rattachée au repli 53 et une troisième paroi 52 dont une extrémité se raccorde transversalement à l'extrémité de la paroi 51 opposée à celle rattachée à la paroi 50.The arm 41 has a first wall 50 (FIG. 11), one end of which is connected to the wall 47 by an elastically deformable U-shaped fold 53, a second wall 51, one end of which is connected transversely to the end of the wall 50 opposite to that attached to the fold 53 and a third wall 52, one end of which connects transversely to the end of the wall 51 opposite to that attached to the wall 50.

Les parois 46 et 52 sont en regard l'une de l'autre et forment une alvéole d'accueil 54 d'une broche 6 de la fiche 7 tandis que la paroi 50 forme comme on le verra ci-après avec la cage 45 et la lame ressort 42 une borne à connexion automatique 55.The walls 46 and 52 are facing each other and form a receiving cavity 54 of a pin 6 of the plug 7 while the wall 50 forms as will be seen hereinafter with the cage 45 and the leaf spring 42 a self-connecting terminal 55.

Les parois 46 et 52 sont légèrement incurvées à leur extrémité libre de sorte qu'elles forment un évasement de guidage 56.The walls 46 and 52 are slightly curved at their free end so that they form a guide flare 56.

En l'absence de broche dans l'alvéole 54 (c'est-à-dire en l'absence de toute contrainte au niveau du repli en U 53) la paroi 50 et la paroi 47 de la cage sont en regard l'une de l'autre et sensiblement parallèles entre elles.In the absence of a pin in the cell 54 (that is to say in the absence of any constraint at the U-fold 53) the wall 50 and the wall 47 of the cage are opposite one on the other and substantially parallel to each other.

La lame ressort flexible 42 comporte un premier tronçon droit 60, deux tronçon incurvés 61 et deux tronçons droits 62 dont la largeur est sensiblement égale à la moitié de la largeur du tronçon droit 60.The flexible leaf spring 42 comprises a first straight section 60, two curved sections 61 and two straight sections 62 whose width is substantially equal to half the width of the straight section 60.

Une extrémité de chaque tronçon incurvé 61 se raccorde à une extrémité du tronçon droit 60 tandis que l'extrémité opposée du tronçon 61 se raccorde à une extrémité d'un tronçon droit 62 correspondant en formant un coude fléchi du côté opposé au tronçon droit 60.One end of each curved section 61 is connected to one end of the straight section 60 while the opposite end of the section 61 is connected to one end of a corresponding straight section 62 forming a bent elbow on the opposite side to the straight section 60.

Chaque tronçon incurvé 61 (respectivement chaque tronçon droit 62) est séparé du tronçon incurvé voisin (respectivement du tronçon droit voisin) par une fente 63.Each curved section 61 (respectively each straight section 62) is separated from the neighboring curved section (or the adjacent straight section, respectively) by a slot 63.

Dans le tronçon droit 60 est également ménagée sur chaque bord une encoche 65.In the straight section 60 is also provided on each edge a notch 65.

Le bouton poussoir 43 comporte une touche d'appui 70, une cloison centrale 71 et deux doigts d'actionnement 72.The push button 43 comprises a support button 70, a central partition 71 and two actuating fingers 72.

Les doigts d'actionnement sont disposés de chaque côté de la cloison 71, l'épaisseur de cette cloison étant légèrement inférieure à la largeur de la fente 63.The actuating fingers are arranged on each side of the partition 71, the thickness of this partition being slightly smaller than the width of the slot 63.

L'assemblage d'un module 4 s'effectue en disposant la lame ressort 42 dans la cage 45 de sorte que les arêtes d'extrémité 64 des tronçons 62 viennent en regard de la surface 57 de la paroi 50 du bras mobile 41 tournée vers la paroi 49 (figure 11).The assembly of a module 4 is performed by placing the spring blade 42 in the cage 45 so that the end edges 64 of the sections 62 are facing the surface 57 of the wall 50 of the mobile arm 41 facing wall 49 (FIG. 11).

La lame ressort 42 est maintenue solidaire de la cage 45 en étant plaquée contre la paroi 49 opposée à la paroi 47 de la cage 45 par l'intermédiaire des pattes 44 formées dans la cage 45 et repliées contre la lame ressort au niveau des encoches 65.The spring blade 42 is held integral with the cage 45 by being pressed against the wall 49 opposite the wall 47 of the cage 45 via the tabs 44 formed in the cage 45 and bent against the spring blade at the notches 65 .

Le poussoir 43 est ensuite également partiellement introduit dans la cage avec la cloison 71 qui se loge entre les tronçons 62 et les tronçons 61 dans la fente 63, chacun des doigts 72 venant se placer au voisinage du tronçon 62 correspondant.The pusher 43 is then also partially introduced into the cage with the partition 71 which is housed between the sections 62 and the sections 61 in the slot 63, each of the fingers 72 being placed in the vicinity of the corresponding section 62.

Chacun des modules 4 est ensuite disposé dans le boîtier isolant 2 avec sa borne à connexion automatique 55 qui est située dans le compartiment 10 et son alvéole 54 dans le compartiment 11 (figure 3).Each of the modules 4 is then placed in the insulating casing 2 with its automatic connection terminal 55 which is located in the compartment 10 and its cell 54 in the compartment 11 (FIG. 3).

On va maintenant décrire l'opération d'introduction d'un câble dans la prise 1 à l'aide des figures 11 et 12.The operation of introducing a cable into the socket 1 will now be described using FIGS. 11 and 12.

La première opération consiste à faire pénétrer le câble rigide 5 au travers du conduit 18 du boîtier 2 dans lequel il doit être inséré jusqu'à ce que l'extrémité dénudée 8 du câble traverse l'ouverture d'insertion 39 correspondante du module 4 et vienne prendre appui contre le tronçon 62 correspondant pour écarter l'arête d'extrémité 64 de ce tronçon de la surface 57 de la paroi d'appui 50 afin de laisser passer l'extrémité 8 entre cette arête et cette paroi.The first operation is to penetrate the rigid cable 5 through the conduit 18 of the housing 2 in which it must be inserted until the stripped end 8 of the cable passes through the corresponding insertion opening 39 of the module 4 and come to bear against the corresponding section 62 to separate the end edge 64 of this section of the surface 57 of the support wall 50 to allow the end 8 to pass between this edge and this wall.

Le mouvement d'enfoncement du câble se poursuit éventuellement jusqu'à ce que l'extrémité de ce câble vienne en butée contre la surface 38 de la paroi 51 tournée vers la lame ressort 42.The driving movement of the cable may continue until the end of this cable abuts against the surface 38 of the wall 51 facing the spring blade 42.

La surface interne 57 de la paroi d'appui 50 forme ainsi pour le câble 5 un siège contre lequel il est maintenu par la lame ressort 42 qui le plaque contre cette surface. Si ce câble une fois installé dans la borne tend à être retiré du bloc, c'est-à-dire s'il est soumis à un effort dirigé dans le sens contraire au sens d'insertion, ce câble aura tendance à entraîner avec lui le tronçon 62, qui va s'arc-bouter et donc le coincer contre la paroi 50, ce qui interdira le retrait de cet élément.The inner surface 57 of the support wall 50 thus forms a seat for the cable 5 against which it is held by the spring blade 42 which plates it against this surface. If this cable once installed in the terminal tends to be removed from the block, that is to say if it is subjected to a force directed in the direction opposite to the direction of insertion, this cable will tend to carry with it the section 62, which will bend and thus wedge against the wall 50, which will prohibit the removal of this element.

Pour le retrait du câble (figure 14), l'opérateur appuie sur la touche 70 du bouton poussoir 43 en direction de la lame ressort 42 de façon à déplacer ce bouton pour plaquer le doigt d'actionnement 72 contre le tronçon 62 correspondant afin de contraindre ce tronçon, l'arête d'extrémité 64 s'écartant alors du siège 57 pour libérer le câble et permettre ainsi de l'extraire de la borne.For removal of the cable (Figure 14), the operator presses the button 70 of the push button 43 towards the spring blade 42 so as to move this button to press the actuating finger 72 against the corresponding section 62 in order to constrain this section, the end edge 64 away from the seat 57 to release the cable and thus to extract it from the terminal.

Il est également possible d'utiliser le bouton poussoir 43 pour contraindre la lame ressort 42 afin de pouvoir introduire dans la borne 55 un câble dont l'âme conductrice serait souple.It is also possible to use the push button 43 to constrain the spring blade 42 so as to introduce into the terminal 55 a cable whose conductive core would be flexible.

Il est également possible de faire pénétrer un second câble dans la borne par l'intermédiaire du second conduit 18 du boîtier, celui-ci sollicitant alors le tronçon 62 voisin du tronçon sollicité précédemment par le premier câble.It is also possible to penetrate a second cable into the terminal via the second conduit 18 of the housing, the latter then urging the section 62 adjacent the section previously requested by the first cable.

On va maintenant décrire l'opération d'introduction d'une broche 6 dans une alvéole 54 correspondante (après qu'au moins câble ait été introduit dans la borne 55) à l'aide des figures 12 et 13.The operation of introducing a pin 6 into a corresponding cell 54 (after at least one cable has been introduced into the terminal 55) will now be described using FIGS. 12 and 13.

Une fois l'extrémité dénudée 8 maintenue entre la paroi d'appui 50 et la lame ressort 42 (figure 12), l'opérateur raccorde la fiche 7 à la prise 1 comme illustré en figure 5.Once the stripped end 8 is held between the support wall 50 and the spring blade 42 (FIG. 12), the operator connects the plug 7 to the receptacle 1 as illustrated in FIG.

Dans un premier temps, les broches 6 traversent les orifices 25 du capot 3 et pénètrent dans le compartiment 11 du boîtier isolant.At first, the pins 6 pass through the orifices 25 of the cover 3 and penetrate into the compartment 11 of the insulating housing.

Lorsque les broches 6 pénètrent dans ce compartiment 11 elles sont dirigées vers les alvéoles 54 et sont guidées par les évasements 56 et les ailettes 58 de ces alvéoles.When the pins 6 enter this compartment 11 they are directed towards the cells 54 and are guided by the flares 56 and the fins 58 of these cells.

Chaque broche 6 en pénétrant dans son alvéole correspondante entraîne une déformation de celle-ci, la paroi mobile 52 ayant tendance à s'écarter de la paroi fixe 46 de cette alvéole appartenant au bâti 40 pour permettre à la broche de pénétrer dans celle-ci.Each pin 6 penetrating into its corresponding cell causes a deformation thereof, the movable wall 52 tending to deviate from the fixed wall 46 of the cell belonging to the frame 40 to allow the pin to enter it .

Le déplacement de la paroi 52 entraîne, par l'intermédiaire de la paroi de liaison 51, la déformation du repli 53 et le déplacement de la paroi d'appui 50 vers la lame ressort 42.The displacement of the wall 52 causes, via the connecting wall 51, the deformation of the fold 53 and the displacement of the bearing wall 50 towards the leaf spring 42.

Au cours du déplacement, l'extrémité de la paroi 50 qui se raccorde à la paroi 51 s'écarte de la paroi 47 en entraînant par l'intermédiaire du câble 5 une déformation supplémentaire de la lame ressort (augmentation de la flèche de la lame ressort), la portion dénudée 8 du câble étant dans ce cas légèrement fléchie (figure 13). Cette déformation supplémentaire de la lame ressort 42 renforce ainsi la pression de contact de cette lame et de la paroi 50 avec le câble.During displacement, the end of the wall 50 which connects to the wall 51 deviates from the wall 47 by driving through the cable 5 an additional deformation of the spring blade (increase of the arrow of the blade spring), the stripped portion 8 of the cable being in this case slightly bent (Figure 13). This additional deformation of the spring blade 42 thus strengthens the contact pressure of this blade and the wall 50 with the cable.

La lame ressort 42 et la paroi 50 sont ainsi judicieusement disposées l'une par rapport à l'autre pour permettre, d'une part, l'insertion d'un câble avec un effort non nul mais réduit entre cette lame et cette paroi (c'est-à-dire uniquement suffisant pour empêcher le retrait du câble en entraînant la lame ressort à s'arc-bouter) et pour garantir, d'autre part, une fois la broche introduite dans l'alvéole, un contact électrique optimal en entraînant un fléchissement supplémentaire de la lame ressort.The spring blade 42 and the wall 50 are thus judiciously arranged relative to one another to allow, on the one hand, the insertion of a cable with a non-zero but reduced force between this blade and this wall ( that is to say only sufficient to prevent the removal of the cable by driving the spring blade to be arched) and to ensure, on the other hand, once the pin introduced in the cell, an optimal electrical contact by causing an additional deflection of the blade spring.

Le contact électrique renforcé permet ainsi de minimiser de façon importante les risques d'échauffement dans la prise lors du passage du courant.The reinforced electrical contact thus significantly minimizes the risk of heating in the socket during the passage of the current.

De plus, le renfort de la pression de contact une fois la broche introduite permet également de compenser les incertitudes sur les caractéristiques des câbles (diamètre, qualité de fabrication, etc).In addition, the reinforcement of the contact pressure once the pin introduced also makes it possible to compensate for the uncertainties on the characteristics of the cables (diameter, quality of manufacture, etc.).

A l'inverse, lorsque la broche 6 est extraite de l'alvéole 54 la paroi d'appui 50 est libérée de la contrainte mécanique à laquelle elle était soumise (dans l'exemple illustré cette paroi retourne dans sa position initiale par rappel élastique du repli en U 53) de sorte que l'extraction du câble en agissant sur la lame ressort par le poussoir 43 (figure 14) est également facilitée (au même titre que l'étape d'insertion de ce câble).Conversely, when the pin 6 is extracted from the cell 54 the support wall 50 is released from the mechanical stress to which it was subjected (in the example shown this wall returns to its initial position by elastic return of the U-fold 53) so that the extraction of the cable by acting on the leaf spring by the pusher 43 (Figure 14) is also facilitated (as well as the insertion step of this cable).

Dans une variante non représentée, la partie mobile de l'alvéole n'est pas une paroi de cette alvéole mais par exemple un doigt en matériau conducteur ou non relié par un mécanisme de liaison à la paroi d'appui de la borne.In a variant not shown, the mobile part of the cell is not a wall of this cell but for example a finger of conductive material or not connected by a connecting mechanism to the bearing wall of the terminal.

Dans une autre variante le bouton poussoir est remplacé par un levier d'actionnement monté à rotation.In another variant the push button is replaced by an actuating lever mounted to rotate.

Dans une autre variante encore, les membres fixes de l'alvéole et de la borne n'appartiennent pas à un même bâti et sont séparés l'un de l'autre.In another variant, the fixed members of the cell and the terminal do not belong to the same frame and are separated from one another.

De nombreuses autres variantes sont possibles en fonction des circonstances, et on rappelle à cet égard que l'invention ne se limite pas aux exemples décrits et représentés.Many other variants are possible depending on the circumstances, and it is recalled in this regard that the invention is not limited to the examples described and shown.
