Abstract

The socket has a filler plate (350) displaced in a plane parallel to a plane formed by a movable protective flap to pass the plate from a closed position in which the plate covers pin passage holes (304) to prevent accessing of pins to electrical contacts, to an open position in which the plate authorizes the accessing of the pins. A locking unit is constituted of a spigot (356), a keyway section (357) and a groove (202), to lock the plate for preventing the plate from being passed from the closed position to the open position, and is activated when the flap is found in raised position. An independent claim is also included for a polarizing slot and electrical socket assembly comprising a base.

Description

La présente invention concerne, d'une manière générale, les prises de courant électrique du type comportant un puits propre à recevoir une fiche complémentaire de raccordement électrique.The present invention relates, in general, electrical power outlets of the type comprising a well adapted to receive a complementary electrical connection plug.

ARRIERE-PLAN TECHNOLOQIQUETECHNICAL BACKGROUND

Elle vise plus particulièrement celles qui comportent d'une part, un obturateur escamotable, plus communément appelé, de manière simplifiée, « éclips », ou « éclipse », qui, à l'encontre de moyens élastiques de rappel, est monté mobile dans son plan entre une position déployée de repos, pour laquelle il occulte des ouvertures de passage, situées au droit d'alvéoles de contact, en interdisant ainsi l'accès à ces alvéoles de contact, et une position rétractée de service, pour laquelle, dûment éclipsé, il libère ces ouvertures de passage et permet ainsi l'accès à ces alvéoles de contact et, d'autre part, un volet mobile de protection qui permet d'éviter le dépôt de salissures à l'intérieur du puits.It is more particularly those which comprise on the one hand, a retractable shutter, more commonly called, in a simplified manner, "eclipse", or "eclipse", which, against resilient return means, is mounted movable in its plane between an extended position of rest, for which it hides passage openings, located at the right of contact cells, thereby preventing access to these contact cells, and a retracted position of service, for which, duly eclipsed it releases these passage openings and thus allows access to these contact cells and, secondly, a movable protective flap which prevents the deposit of dirt inside the well.

Ainsi qu'on le sait, l'obturateur escamotable ainsi mis en oeuvre constitue un organe de sécurité qui, en position de repos, s'oppose à ce qu'un quelconque élément par exemple métallique introduit de manière malencontreuse, par exemple par un enfant, dans l'une des ouvertures de passage de l'élément avant ne puisse atteindre l'alvéole de contact correspondant, celui-ci étant normalement sous tension.As is known, the retractable shutter thus used constitutes a safety member which, in the rest position, prevents any element, for example metal, unintentionally introduced, for example by a child in one of the passage openings of the front element can not reach the corresponding contact cell, it is normally under tension.

On connaît de l'état de la technique des prises à puits avec un volet mobile pourvu d'un obturateur escamotable.Known sockets are known from the state of the art with a movable flap provided with a retractable shutter.

On connaît plus particulièrement un type de prise dans laquelle la translation du volet dans le puits est verrouillée par des moyens de verrouillage en translation, qui sont désactivés lors de l'introduction d'une fiche. Dans ce type de prise, l'introduction de la fiche complémentaire de raccordement électrique dans la prise de courant libère le volet en translation et entraîne son déplacement en autorisant ainsi l'accès aux contacts électriques internes à la prise. En pratique, c'est le déplacement de l'obturateur qui désactive les moyens de verrouillage en translation.In particular, a type of plug is known in which the translation of the shutter in the well is locked by translation locking means, which are deactivated during the introduction of a plug. In this type of socket, the introduction of the additional connection plug electrical outlet in the power outlet releases the flap in translation and causes its movement by allowing access to internal electrical contacts to the socket. In practice, it is the displacement of the shutter which deactivates the locking means in translation.

Les broches de la fiche traversent donc le volet, puis la poursuite de la poussée exercée au moyen de la fiche a pour conséquence que le volet se déplace axialement dans le puits de la prise et que les broches de la fiche entrent finalement en contact avec les alvéoles de contact de la prise. Dans ce type de prise, la fiche peut donc être engagée à travers le volet sans qu'il y ait contact avec les contacts électriques. Lors du retrait de la fiche, le volet remonte au sommet du puits sous l'action de moyens de rappel, l'obturateur se referme sous l'action de moyens de rappel après l'extraction des broches, ce qui a pour conséquence d'activer les moyens de verrouillage en translation du volet dans le puits. Une telle prise est notamment connue du document FR2886775 .The pins of the plug thus pass through the shutter, then the continuation of the thrust exerted by means of the plug has the consequence that the flap moves axially in the well of the socket and that the pins of the plug finally come into contact with the contact cells of the socket. In this type of plug, the plug can be engaged through the shutter without contact with the electrical contacts. When removing the plug, the shutter rises to the top of the well under the action of return means, the shutter closes under the action of return means after the extraction of the pins, which has the consequence of activate the locking means in translation of the flap in the well. Such a decision is notably known from the document FR2886775 .

Les prises connues donnent globalement satisfaction. Cependant, on aimerait améliorer la sécurité des prises à volet mobile et obturateur, notamment en autorisant l'ouverture de ce dernier uniquement lorsque la fiche est dans une position dans laquelle ses broches sont susceptibles d'être en contact avec les broches, de manière à garder l'obturateur fermé à tout autre moment, en empêchant ainsi l'accès aux contacts électriques.The known catches give overall satisfaction. However, we would like to improve the security of the mobile shutter and shutter, including allowing the opening of the latter only when the plug is in a position in which its pins are likely to be in contact with the pins, so as to keep the shutter closed at all other times, thus preventing access to the electrical contacts.

EXPOSE DE L'INVENTIONSUMMARY OF THE INVENTION

D'une manière générale, la présente invention vise à améliorer ce genre de prises, notamment sur le plan de la sécurité.In general, the present invention aims to improve this type of catch, particularly in terms of safety.

De manière plus précise, elle a pour objet une prise de courant à puits comportant au droit du fond du puits des contacts électriques pour une fiche de raccordement électrique ayant des broches de raccordement électrique complémentaires et comportant
un volet de protection du puits, pourvu de trous prévus pour le passage des broches de la fiche de raccordement électrique et monté mobile en translation dans le puits, entre une position haute, dans laquelle il est sensiblement affleurant avec le rebord du puits et une position basse dans laquelle il est en butée contre le fond du puits, un moyen de rappel sollicitant en permanence le volet vers la position haute,
un obturateur pour les trous de passage de broche ménagés dans le volet, l'obturateur étant monté mobile sur le volet et conformé de manière à se déplacer, dans un plan parallèle à celui formé par le volet en vue de passer d'une position de fermeture, dans laquelle il recouvre les trous de passage de broche interdisant ainsi aux broches l'accès aux contacts électriques, à une position d'ouverture, dans laquelle il autorise cet accès, un moyen de rappel sollicitant en permanence l'obturateur vers la position de fermeture,
la prise étant caractérisée en ce qu'elle comporte des moyens de verrouillage de l'obturateur pour l'empêcher de passer de la position de fermeture à la position d'ouverture, les moyens de verrouillage étant propres à être activés lorsque le volet se trouve en position haute.More specifically, it relates to a well socket having, at the bottom of the well, electrical contacts for an electrical connection plug having complementary electrical connection pins and comprising
a well protection flap provided with holes provided for the passage of the pins of the electrical connection plug and mounted movably in translation in the well, between a high position, in which it is substantially flush with the rim of the well and a low position in which it is in abutment against the bottom of the well, a biasing means permanently urging the flap towards the position high,
a shutter for the pinholes provided in the shutter, the shutter being mounted movably on the shutter and shaped so as to move in a plane parallel to that formed by the shutter in order to pass from a position of closing, in which it covers the pinholes thus preventing the pins access to the electrical contacts, to an open position, in which it allows access, a biasing means permanently urging the shutter to the position closing,
the socket being characterized in that it comprises means for locking the shutter to prevent it from passing from the closed position to the open position, the locking means being adapted to be activated when the shutter is located in high position.

Ainsi, avantageusement, la sécurité de la prise est améliorée, puisque l'obturateur est verrouillé en position fermée de sécurité tant que le volet se trouve en position haute.Thus, advantageously, the safety of the grip is improved, since the shutter is locked in the closed safety position as long as the flap is in the high position.

Suivant un aspect avantageux de l'invention, éventuellement combiné, les moyens de verrouillage sont propres à être désactivés lorsque le volet se trouve en position basse, autorisant le déplacement de l'obturateur de la position de fermeture à la position d'ouverture au contact des broches de la fiche complémentaire de raccordement électrique en phase de raccordement à la prise, autorisant ainsi aux broches de la fiche l'accès aux contacts électriques correspondants se trouvant au droit du fond du puits.According to an advantageous aspect of the invention, possibly combined, the locking means are adapted to be deactivated when the flap is in the low position, allowing the shutter to move from the closed position to the open position in contact pins of the complementary plug of electrical connection in phase of connection to the socket, thus allowing the pins of the plug access to the corresponding electrical contacts located at the bottom of the well.

Ainsi, avantageusement, l'ouverture de l'obturateur et donc l'accès aux contacts électriques est autorisée uniquement en position basse du volet. Lors de l'introduction de la fiche dans le puits, sous l'effet du déplacement de la fiche, le volet passe d'abord de la position haute à la position basse, et c'est seulement à ce moment que l'obturateur est déverrouillé, lorsque les broches sont au plus près des contacts électriques qui se trouvent de l'autre coté du volet. La sécurité s'en trouve sensiblement améliorée, puisque l'accès aux contacts électrique n'est autorisé qu'au dernier moment.Thus, advantageously, the opening of the shutter and therefore the access to the electrical contacts is allowed only in the lower position of the shutter. When inserting the plug into the well, under the effect of the movement of the plug, the flap first goes from the high position to the low position, and it is only then that the shutter is unlocked, when the pins are closer to the electrical contacts on the other side of the shutter. The security is significantly improved, since access to electrical contacts is allowed at the last moment.

Suivant des caractéristiques avantageuses, éventuellement combinées :

  • l'obturateur est adapté à se déplacer en rotation entre la position de fermeture et la position d'ouverture, un ressort de rappel le sollicitant en permanence vers sa position de fermeture, et en ce que les moyens de verrouillage de l'obturateur sont des moyens de blocage en rotation ;
  • les moyens de blocage en rotation sont adaptés à coopérer avec un moyen prévu sur la paroi du puits de manière à activer lesdits moyens de blocage en rotation lorsque le volet se trouve en position haute dans le puits et de manière à désactiver lesdits moyens de blocage en rotation lorsque le volet se trouve en position basse dans le puits ;
  • les moyens de blocage en rotation comportent une rainure pratiquée dans la paroi du puits et un ergot faisant saillie de l'obturateur rotatif vers la paroi du puits et destiné à s'engager dans la rainure, la rainure étant profilée de telle sorte que
    lorsque le volet se trouve en position haute dans le puits, la rainure présente une section étroite n'autorisant pas l'ergot à se déplacer dans le plan parallèle à celui formé par le volet, empêchant ainsi la rotation de l'obturateur et,
    lorsque le volet se trouve en position basse dans le puits, la rainure présente un élargissement autorisant à l'ergot un degré de liberté dans le plan parallèle à celui formé par le volet, l'élargissement étant dimensionné pour autoriser la rotation de l'obturateur depuis sa position de fermeture vers sa position d'ouverture.
    Il est donc tiré avantage du mouvement du volet causé par l'introduction de la fiche pour libérer la rotation de l'obturateur. La translation du volet dans le puits libère la rotation et donc la possibilité d'ouverture de l'obturateur.
    Suivant une caractéristique avantageuse de l'invention, l'ergot présente une forme en biseau et la rainure présente entre sa portion étroite et son élargissement une rampe complémentaire destinée à coopérer avec le biseau, de manière à transformer un mouvement de translation du volet vers la position haute en un mouvement de rotation de l'obturateur vers sa position de fermeture via son ergot de manière à ce que l'obturateur se trouve en position fermée avant que l'ergot ne pénètre dans la section étroite de la rainure autorisant ainsi la remontée du volet vers la position haute.
    Avantageusement, suivant cette dernière caractéristique, la remontée du volet en position haute n'est possible que lorsque l'obturateur est fermé. La coopération de formes entre l'ergot et la rampe permet avantageusement de transformer l'effort des moyens de rappel du volet vers la position haute en mouvement de rotation de l'obturateur. Ceci contribue à la sécurité de la prise selon l'invention, en permettant d'éviter un coincement du volet avec l'obturateur en position ouverte dans le fond du puits.
    Suivant une caractéristique avantageuse de l'invention, l'obturateur est conformé de manière à transformer le mouvement de translation des broches la fiche de raccordement électrique en phase d'introduction dans la prise en mouvement de rotation autour de lui-même.
    De cette manière selon l'invention, l'obturateur est conformé de manière à transformer le mouvement de translation des broches de la fiche de raccordement électrique en cours de raccordement à la prise, en mouvement de rotation autour de lui-même, pour passer de la position de fermeture à la position d'ouverture, en effectuant une rotation sur lui-même. Ainsi, une fois que le volet a quitté la position haute et que le verrouillage en rotation de l'obturateur est libéré, le mouvement de translation de l'introduction de la fiche dans la prise est mis à profit pour ouvrir l'obturateur et autoriser l'accès aux contacts électriques.
    Pour l'alimentation de certains appareillages électroniques, comme par exemple les calculateurs, il est souhaitable de disposer d'un réseau de distribution électrique de meilleure qualité et présentant notamment une plus grande stabilité de tension et une bonne protection contre les micro-coupures.
    Lorsqu'un tel réseau existe, il doit être exclusivement réservé à l'alimentation des appareillages de ce type pour éviter que le branchement occasionnel d'un autre appareil électrique n'en affecte la stabilité ou y introduise des parasites. Suivant un aspect avantageux, la présente invention permet d'éviter ce type de branchement fautif.
    Elle propose à cet effet une prise telle que décrite supra dont l'obturateur est adapté à transformer le mouvement de translation de la fiche en phase d'introduction en rotation au contact d'un détrompeur spécifique à la prise monté sur la fiche de raccordement à cet effet, le détrompeur étant l'unique moyen pour transformer le mouvement de translation de la fiche en phase d'introduction en rotation de l'obturateur.
    Ainsi, avantageusement, la présente invention est mise à profit pour interdire l'accès d'une prise donnée à des fiches qui ne seraient pas pourvues d'un détrompeur correspondant. En d'autres termes, suivant cette caractéristique, il est nécessaire de disposer d'un détrompeur pour pouvoir utiliser cette prise. Dans ce cas, le détrompeur devient une sorte de clé permettant d'utiliser une prise, et donc d'accéder à un réseau électrique donné.
    Suivant un aspect avantageux, l'obturateur présente une branche disposée dans son plan de rotation, et dont l'extrémité est conformée en rampe, et en ce que le détrompeur présente un doigt dont l'extrémité est conformée en biseau de manière à coopérer avec la rampe de la branche de l'obturateur pour transformer le mouvement de translation du détrompeur et de la fiche en phase d'introduction et en rotation de l'obturateur de sa positon de fermeture à sa position d'ouverture.
    Il est donc tiré avantage du mouvement de translation de l'introduction de la fiche et du détrompeur dans la prise pour ouvrir l'obturateur et autoriser l'accès aux contacts électriques.
    Suivant un autre aspect, l'invention concerne également un détrompeur et une prise telle que décrite supra, le détrompeur présentant une plaque percée de trous permettant de laisser passer les broches de la fiche et de laisser accès aux éventuelles alvéoles de contact électrique de la fiche à d'éventuelles broches de la prise, la plaque étant destinée à être enfilée à l'extrémité de la fiche, et présentant des moyens permettant de transformer le mouvement de translation de la fiche en phase d'introduction en rotation de l'obturateur en coopération avec des moyens complémentaires prévus à cet effet sur la prise.
    Il est à noter que, quels que soient les modes de réalisation, la prise et notamment le puits, le volet, ainsi que l'obturateur, peuvent avoir un différent nombre et une différente répartition et forme des trous de broche, de manière à s'adapter à différentes dimensions géométriques de prises électriques et de fiches complémentaires de raccordement électrique, notamment pour différentes formes et positionnement de broches de prise de terre, notamment en fonction des standards et des normes en vigueur dans un pays donné.
    D'une manière générale, la présente invention s'applique à tout type de prises à puits avec volet affleurant, quelque soit leur standard électrique (nombre de broches, forme des broches, distances entre les broches, forme des fiches, etc.).
According to advantageous characteristics, possibly combined:
  • the shutter is adapted to move in rotation between the closed position and the open position, a return spring permanently urging it towards its closed position, and in that the shutter locking means are rotation locking means;
  • the rotational locking means are adapted to cooperate with means provided on the wall of the well so as to activate said rotational locking means when the flap is in the upper position in the well and so as to deactivate said locking means in rotation when the flap is in the lower position in the well;
  • the rotational locking means comprise a groove formed in the wall of the well and a lug protruding from the rotary shutter towards the wall of the well and intended to engage in the groove, the groove being profiled so that
    when the flap is in the upper position in the well, the groove has a narrow section that does not allow the spigot to move in the plane parallel to that formed by the flap, thus preventing the shutter from rotating and,
    when the flap is in the lower position in the well, the groove has a widening allowing the lug a degree of freedom in the plane parallel to that formed by the flap, the enlargement being dimensioned to allow the rotation of the shutter from its closed position to its open position.
    It is therefore taken advantage of the movement of the flap caused by the introduction of the plug to release the rotation of the shutter. The translation of the shutter into the well releases the rotation and therefore the possibility of opening the shutter.
    According to an advantageous characteristic of the invention, the lug has a bevelled shape and the groove present between its narrow portion and its widening a complementary ramp intended to cooperate with the bevel, so as to transform a translation movement of the shutter towards the high position into a rotational movement of the shutter towards its closed position via its lug so that the shutter is in the closed position before the lug enters the narrow section of the groove allowing the raising of the flap to the high position.
    Advantageously, according to this last characteristic, the raising of the flap in the high position is possible only when the shutter is closed. The cooperation of forms between the lug and the ramp advantageously makes it possible to transform the force of the return means of the flap towards the high position into rotational movement of the shutter. This contributes to the safety of the socket according to the invention, by preventing a jamming of the shutter with the shutter in the open position in the bottom of the well.
    According to an advantageous characteristic of the invention, the shutter is shaped so as to transform the translational movement of the pins the electrical connection plug into the introduction phase into the rotating motion around itself.
    In this way according to the invention, the shutter is shaped so as to transform the translational movement of the pins of the electrical connection plug being connected to the socket, in rotation movement around itself, to move from the closed position to the open position, rotating on itself. Thus, once the shutter has left the high position and the locking in rotation of the shutter is released, the translational movement of the introduction of the plug into the socket is used to open the shutter and allow access to electrical contacts.
    For the supply of certain electronic equipment, such as computers for example, it is desirable to have a better quality electrical distribution network and in particular having greater voltage stability and good protection against micro-cuts.
    When such a network exists, it must be exclusively reserved for powering equipment of this type to prevent the connection Occasionally another electrical appliance affects its stability or introduces noise. According to an advantageous aspect, the present invention makes it possible to avoid this type of faulty connection.
    It proposes for this purpose a socket as described supra whose shutter is adapted to transform the translational movement of the plug into the introduction phase in rotation in contact with a specific key to the socket mounted on the connection plug to this effect, the keying being the only way to transform the translational movement of the plug into the introduction phase in rotation of the shutter.
    Thus, advantageously, the present invention is used to prevent access of a given plug to the plugs that would not be provided with a corresponding key. In other words, according to this characteristic, it is necessary to have a key to use this socket. In this case, the keying becomes a kind of key to use a socket, and thus to access a given power grid.
    According to an advantageous aspect, the shutter has a branch disposed in its plane of rotation, and whose end is shaped as a ramp, and in that the polarizer has a finger whose end is shaped in a bevel so as to cooperate with the ramp of the shutter branch to transform the translational movement of the polarizer and the plug in the insertion phase and rotation of the shutter from its closing position to its open position.
    It is therefore taken advantage of the translational movement of the introduction of the plug and the key in the socket to open the shutter and allow access to the electrical contacts.
    According to another aspect, the invention also relates to a polarizer and a socket as described above, the polarizer having a plate pierced with holes for passing the pins of the plug and to allow access to any electrical contact cells of the plug to any pins of the socket, the plate being intended to be threaded at the end of the plug, and having means for transforming the translation movement of the plug into the introduction phase in rotation of the shutter in cooperation with complementary means provided for this purpose on the plug.
    It should be noted that, whatever the embodiments, the socket and in particular the well, the shutter, and the shutter, can have a different number and a different distribution and shape of the pin holes, so that adapting to different geometrical dimensions of electrical sockets and additional electrical connection plugs, in particular for different forms and positioning of earth pins, in particular according to the standards and standards in force in a given country.
    In general, the present invention applies to any type of wells with flush flap, regardless of their electrical standard (number of pins, shape of the pins, distances between the pins, shape of the cards, etc.).

Comme visible en figure 1 une prise de courant 100 selon l'invention présente un socle 600 sur lequel est monté un puits 200 dans lequel est monté à translation un volet mobile 300.As visible in figure 1 a socket 100 according to the invention has a base 600 on which is mounted a well 200 in which is mounted in translation a movable flap 300.

Comme cela est plus visible en figure 2, le socle 600 est pourvu de contacts 500 maintenus en place par une plaquette 400 qui vient s'encliqueter au fond du socle 600.As this is more visible in figure 2 the base 600 is provided with contacts 500 held in place by a plate 400 which snaps into the bottom of the base 600.

Le volet mobile 300 est monté à translation dans le puits 200 qui vient lui-même s'encliqueter dans le socle 600 au dessus de la plaquette 400.The movable flap 300 is mounted in translation in the well 200 which itself comes snap into the base 600 above the wafer 400.

La plaquette 400 est percée de trous pour le passage des broches d'une fiche destinées à être raccordées aux contacts 500.The plate 400 is pierced with holes for the passage of the pins of a plug to be connected to the contacts 500.

Deux pattes 302 solidaires du volet 300 sont prévues pour assurer le rappel du volet vers la position haute affleurante avec le rebord 201 du puits 200. Le rappel se fait par l'intermédiaire de deux ressorts hélicoïdaux 601 qui prennent appui au fond du socle 600 et dont les extrémités opposées se fixent de manière connue en soi autour de pions coniques 303 prévus à cet effet aux extrémités des pattes 302.Two lugs 302 integral with the flap 300 are provided to ensure the return of the flap to the flush upper position with the rim 201 of the well 200. The return is via two helical springs 601 which bear against the bottom of the base 600 and whose opposite ends are fixed in a manner known per se around conical pins 303 provided for this purpose at the ends of the tabs 302.

Le volet mobile 300 abrite un obturateur 350 recouvert d'un enjoliveur 301 présentant des trous pour le passage des broches d'une fiche destinées à être raccordées aux contacts 500.The movable flap 300 houses a shutter 350 covered with a hubcap 301 having holes for the passage of the pins of a plug to be connected to the contacts 500.

L'obturateur 350 est visible plus particulièrement en figures 3A et 3B. L'obturateur 350 présente un anneau central 351 et deux oreilles 352 pour boucher les trous de passage de broches 304 aménagés dans le volet 300. Avantageusement, le trou central 305 de passage de broche est entouré d'un rebord 306 formant tourillon servant de pivot à l'anneau central 351 de l'obturateur 350. En pratique, le trou central 305 de passage de broche est destiné au passage d'une broche de mise à la terre et n'est donc pas pourvu d'un obturateur. Un moyen de rappel sous forme d'un ressort hélicoïdal 307 est prévu pour solliciter en permanence l'obturateur vers la position de fermeture telle qu'illustré en figure 3A. Le ressort 307 prend appui sur une butée 308 prévue sur le volet 300 et, par son extrémité opposée, sur un méplat 354 prévu sur l'anneau central 351 de l'obturateur. Ce méplat 354 est pourvu d'un pion conique 355 de guidage du ressort selon le même principe que les pions 303. Deux butées 309 sont prévues sur le volet 300 pour définir la position de fermeture de l'obturateur, les deux oreilles 352 venant en butée sur les butées 309 sous l'effet de l'action du ressort de rappel 307.The shutter 350 is visible more particularly in Figures 3A and 3B . The shutter 350 has a central ring 351 and two lugs 352 for plugging the pinholes 304 formed in the flap 300. Advantageously, the central hole 305 spindle passage is surrounded by a flange 306 forming a pivot pin to the central ring 351 of the shutter 350. In practice, the central hole 305 spindle passage is intended for the passage of a grounding pin and is therefore not provided with a shutter. A return means in the form of a helical spring 307 is provided for permanently urging the shutter towards the closed position as illustrated in FIG. figure 3A . The spring 307 is supported on a stop 308 provided on the flap 300 and, at its opposite end, on a flat 354 provided on the central ring 351 of the shutter. This flat 354 is provided with a conical pin 355 for guiding the spring according to the same principle as the pins 303. Two stops 309 are provided on the flap 300 to define the closed position of the shutter, the two lugs 352 coming into position. stop on the stops 309 under the effect of the action of the return spring 307.

Ainsi monté, l'obturateur est adapté à se déplacer en rotation suivant un plan parallèle au plan du volet 300 jusqu'à la position de fermeture tel qu'illustré en figure 3A et 3B.Thus mounted, the shutter is adapted to move in rotation along a plane parallel to the plane of the shutter 300 to the closed position as illustrated in FIG. figure 3A and 3B .

Un ergot 356 est prévu en saillie sur l'anneau central 351 de l'obturateur 350, pour servir de moyen de blocage en rotation à ce dernier. Une rainure 202 est pratiquée dans la paroi 203 du puits 200. L'ergot 356 faisant saillie de l'obturateur 350 est dimensionné de manière à s'engager dans la rainure 202.A lug 356 is provided projecting on the central ring 351 of the shutter 350, to serve as a locking means in rotation to the latter. A groove 202 is made in the wall 203 of the well 200. The lug 356 protruding from the shutter 350 is sized to engage the groove 202.

Comme visible plus particulièrement en 3B, la rainure 202 présente à son sommet proche du rebord 201 du puits, une section étroite 204, et dans sa partie inférieure, la rainure présente un élargissement 205.As seen more particularly in 3B, the groove 202 has at its apex near the rim 201 of the well, a narrow section 204, and in its lower part, the groove has a widening 205.

Ainsi, lorsque le volet 300 se trouve en position haute dans le puits 200 tel qu'illustré en figure 3A, l'ergot 356 se trouve dans la section étroite 204 de la rainure 202, ce qui empêche la rotation de l'obturateur 350. Lorsque le volet 300 a été déplacé en position basse, comme visible en figure 3B, sous l'effet de l'introduction d'une fiche non représentée, l'ergot se trouve au niveau de l'élargissement 205 de la rainure 202, ce qui autorise la rotation de l'obturateur depuis sa position de fermeture jusqu'à sa position d'ouverture tel que visible en figure 3B.Thus, when the flap 300 is in the up position in the well 200 as illustrated in FIG. figure 3A , the lug 356 is in the narrow section 204 of the groove 202, which prevents the rotation of the shutter 350. When the flap 300 has been moved to the lower position, as visible in FIG. figure 3B , under the effect of the introduction of a plug not shown, the lug is at the widening 205 of the groove 202, which allows the rotation of the shutter from its closed position to its open position as visible in figure 3B .

Comme visible particulièrement en figures 3B, 4A et 4B, l'ergot 356 présente une forme en biseau. La rainure 202 présente entre sa portion étroite 204 et son élargissement 205 une rampe 210 complémentaire et destinée à coopérer avec le biseau de l'ergot 356. Ainsi, en coopération avec la rampe 210, un mouvement de translation du volet 300 vers la position haute générée par les ressorts 601 est transformé en un mouvement de l'obturateur vers sa position de fermeture, via la partie biseautée de l'ergot avant que celui-ci ne pénètre dans la section étroite 204 de la rainure 202. Cette disposition permet d'éviter d'une part le coincement en position ouverte de l'obturateur 350 lorsque le volet 300 se trouve au fonds du puits, et, d'autre part, de faciliter le retour de l'ergot dans la section étroite 204 de la rainure 202 pour permettre ainsi la remontée du volet vers sa position haute affleurante telle que visible en figure 3A.As visible especially in Figures 3B , 4A and 4B , the lug 356 has a beveled shape. The groove 202 has between its narrow portion 204 and its widening 205 a complementary ramp 210 and intended to cooperate with the bevel of the lug 356. Thus, in cooperation with the ramp 210, a translation movement of the flap 300 to the high position generated by the springs 601 is transformed into a movement of the shutter towards its closed position, via the beveled portion of the lug before it penetrates into the narrow section 204 of the groove 202. This arrangement makes it possible to avoid on the one hand jamming open position of the shutter 350 when the flap 300 is at the bottom of the well, and, secondly, to facilitate the return of the pin in the narrow section 204 of the groove 202 to allow the raising of the flap to its high flush position as visible in figure 3A .

L'obturateur est adapté à transformer le mouvement de translation de broche d'une fiche de raccordement en phase d'introduction (non représentée) dans la prise en mouvement de rotation autour de lui-même, à l'aide de profil de rampe 357 prévu sur ses oreilles 352 suivant une disposition connue en soi. En pratique, lorsqu'une fiche est introduite dans la prise 100 selon l'invention, la translation des broches entraîne une translation du volet 300 de sa position supérieure affleurante vers sa position basse dans la mesure où l'ergot 356 est engagé dans la partie étroite 204 de la rainure 202, ce qui verrouille toute possibilité de rotation de l'obturateur. Une fois la position basse atteinte par le volet 300 sous l'effet de l'introduction de la fiche, l'ergot 356 se trouve libéré dans l'élargissement 205 de la rainure, et l'obturateur peut tourner sur lui-même sous l'effet de l'introduction des broches via l'effet des rampes 357 à l'encontre du ressort de rappel 307. Ainsi, l'accès au contact 500 n'est autorisé pour les broches que lorsque celles-ci se trouvent à proximité desdits contacts. En d'autres termes le contact électrique n'est autorisé qu'au dernier moment.The shutter is adapted to transform the spindle translation movement of a connection plug into the insertion phase (not shown) in the rotating motion around itself, by means of ramp profile 357. provided on his ears 352 according to a provision known per se. In practice, when a plug is inserted into the socket 100 according to the invention, the translation of the pins causes a translation of the flap 300 from its upper flush position to its lower position in that the lug 356 is engaged in the part narrow 204 of the groove 202, which locks any possibility of rotation of the shutter. Once the low position reached by the flap 300 under the effect of the introduction of the plug, the pin 356 is released in the enlargement 205 of the groove, and the shutter can turn on itself under the the effect of the introduction of the pins via the effect of the ramps 357 against the return spring 307. Thus, access to the contact 500 is allowed for the pins only when they are in proximity to said contact. In other words, the electrical contact is only allowed at the last moment.

Lors du retrait de la fiche, l'ergot 356 empêche la remontée du volet 300 tant que l'obturateur n'est pas fermé. Une fois la fiche extraite, l'obturateur se referme sous l'effet du ressort 307 combiné à l'effet de rampe de la partie biseautée de l'ergot 356 en coopération avec la rampe 210 sous l'effet des ressorts de rappel 601. L'obturateur vient alors automatiquement en position fermée en butée contre les butées 309 et l'ergot 356 passe dans la portion étroite 204 de la rainure 202 avant de remonter avec le volet en position haute affleurante sous l'effet des ressorts de rappel 601. Avantageusement, on comprend que la fermeture de l'obturateur est assurée systématiquement avant toute possibilité de remontée vers la position haute affleurante lors de l'extraction de la fiche. La coopération de la rampe 210 et de la partie biseautée de l'ergot 356 permet d'éviter tout coincement de l'obturateur en position ouverte.When removing the plug, the pin 356 prevents the raising of the shutter 300 as the shutter is not closed. Once the plug extracted, the shutter closes under the effect of the spring 307 combined with the ramp effect of the beveled portion of the lug 356 in cooperation with the ramp 210 under the effect of the return springs 601. The shutter then automatically comes into position closed in abutment against the stops 309 and the lug 356 passes into the narrow portion 204 of the groove 202 before returning with the flap in the upper flush position under the effect of the return springs 601. Advantageously, it is understood that the closure of the shutter is systematically provided before any possibility of rising to the upper flush position during the extraction of the plug. The cooperation of the ramp 210 and the tapered portion of the lug 356 avoids any jamming of the shutter in the open position.

Dans le dispositif selon l'invention, la position de mise en attente de la fiche, c'est à dire de laisser passer la fiche de l'autre côté du plan de l'obturateur pendant la descente de l'obturateur vers les contacts électriques du fond du puits est rendue impossible.In the device according to the invention, the standby position of the plug, that is to say to let the plug on the other side of the plane of the shutter during the descent of the shutter to the electrical contacts from the bottom of the well is rendered impossible.

Un autre mode de réalisation d'une prise 101 conforme à l'invention est représenté en figures 5 à 7. Ce mode de réalisation est particulièrement adapté à protéger un réseau de distribution électrique de meilleure qualité d'un branchement occasionnel ou accidentel d'un appareil électrique qui n'y serait pas destiné.Another embodiment of a socket 101 according to the invention is represented by Figures 5 to 7 . This embodiment is particularly suitable for protecting a better quality electrical distribution network from an occasional or accidental connection of an electrical appliance that is not intended for this purpose.

Tout comme dans le mode de réalisation précédent, et comme visible en particulier en figure 5, la prise 101 présente sensiblement la même structure que la prise 100 décrite précédemment : la prise 101 présente un socle 600 sur lequel est monté un puits 200 dans lequel est monté en translation un volet mobile 320.As in the previous embodiment, and as visible in particular in figure 5 , the socket 101 has substantially the same structure as the socket 100 described above: the socket 101 has a base 600 on which is mounted a well 200 in which is mounted in translation a movable flap 320.

Le socle 600 est pourvu de contact 500 maintenu en place par une plaquette 400 qui vient s'encliqueter au fonds du socle 600.The base 600 is provided with contact 500 held in place by a plate 400 which snaps into the bottom of the base 600.

Tout comme dans le mode de réalisation précédent, le volet mobile 320 est monté en translation dans le puits 200, qui vient lui-même s'encliqueter dans le socle 600 au dessus de la plaquette 400.As in the previous embodiment, the movable flap 320 is mounted in translation in the well 200, which itself comes snap into the base 600 above the plate 400.

Le rappel du volet 300 en position haute s'effectue de la même manière que dans le mode de réalisation précédent et ne sera pas décrit plus en détail ici.The return of the flap 300 in the high position is carried out in the same manner as in the previous embodiment and will not be described in more detail here.

L'obturateur 370 de la prise 101 est très similaire à l'obturateur 350 de la prise 100 décrite précédemment. L'ergot 376 est en particulier identique à l'ergot 356 ainsi que la coopération avec la rainure correspondante au niveau du puits 200. Le fonctionnement du dispositif de verrouillage en rotation de l'obturateur est identique au mode de réalisation décrit précédemment, c'est pourquoi ces éléments ne seront pas décrits plus en détail ici.The shutter 370 of the socket 101 is very similar to the shutter 350 of the socket 100 described above. Ergot 376 is in particular identical to the pin 356 and the cooperation with the corresponding groove at the level of the well 200. The operation of the locking device in rotation of the shutter is identical to the embodiment described above, that is why these elements will not be described more in detail here.

Comme visible en figure 5, une fiche 700 pourvue d'un détrompeur 750 est destinée à être raccordée au contact 500 de la prise 101.As visible in figure 5 , a plug 700 provided with a polarizer 750 is intended to be connected to the contact 500 of the socket 101.

Dans la prise 101, les oreilles de l'obturateur 370 ne sont pas pourvues de rampes comme dans le mode de réalisation précédent, mais présentent une section plate ne permettant pas la transformation d'un mouvement de translation de broche en mouvement de rotation de l'obturateur. Au lieu de cela, un bras 372 fait saillie de l'anneau central 371 de l'obturateur 370. Ce bras 372 présente une surface formant rampe 373 prévue pour coopérer avec le doigt 751 d'un détrompeur 750 monté sur une fiche 700 destinée à être raccordée à la prise 101. L'extrémité du bras 751 présente une forme en biseau prévue pour coopérer avec la rampe 373 de l'obturateur de manière à transformer le mouvement de translation de la fiche en un mouvement de rotation de l'obturateur.In the socket 101, the ears of the shutter 370 are not provided with ramps as in the previous embodiment, but have a flat section that does not allow the transformation of a spindle translation movement into rotational movement of the spindle. 'shutter. Instead, an arm 372 protrudes from the central ring 371 of the shutter 370. This arm 372 has a ramp surface 373 provided to cooperate with the finger 751 of a polarizer 750 mounted on a plug 700 for The end of the arm 751 has a bevelled shape provided to cooperate with the ramp 373 of the shutter so as to transform the translation movement of the plug into a rotational movement of the shutter.

Un enjoliveur 321 est prévu pour recouvrir l'obturateur monté dans le volet de manière similaire à l'enjoliveur 301, à la différence près qu'il présente un trou supplémentaire 322 pour le passage du doigt 751 du détrompeur 750.A trim 321 is provided to cover the shutter mounted in the shutter similarly to the hubcap 301, with the difference that it has an additional hole 322 for the passage of the finger 751 of the polarizer 750.

Le détrompeur 750 et son positionnement sur la fiche 700 sont plus particulièrement visibles en figure 6A et 6B. La fiche 700 est une fiche standard sur laquelle est rajouté un détrompeur 750. Comme visible plus particulièrement en figures 6A et 6B, le détrompeur 750 présente une plaque 752 percée de trous permettant de laisser passer les broches de la fiche, la plaque étant destinée à être enfilée à l'extrémité de la fiche, et présentant un doigt 751 dont l'extrémité est biseautée pour permettre de transformer le mouvement de translation de la fiche en phase d'introduction en rotation de l'obturateur en coopération avec la rampe 373 complémentaire prévue à cet effet.The polarizer 750 and its positioning on the card 700 are more particularly visible in FIGS. 6A and 6B . The plug 700 is a standard plug on which is added a polarizer 750. As visible more particularly in Figures 6A and 6B , the polarizer 750 has a plate 752 pierced with holes for passing the pins of the plug, the plate being intended to be threaded at the end of the plug, and having a finger 751 whose end is beveled to allow converting the translational movement of the plug into the introduction phase in rotation of the shutter in cooperation with the ramp 373 complementary provided for this purpose.

Suivant une variante non illustrée, lorsque la prise est équipée d'une broche de prise de terre, la plaque du détrompeur est percée d'un trou correspondant pour laisser accès à une éventuelle alvéole de contact électrique de prise de terre de la fiche.According to a variant not illustrated, when the socket is equipped with a grounding pin, the keying plate is pierced with a hole corresponding to allow access to a possible socket electrical contact socket of the plug.

Comme visible plus particulièrement en figure 7, le doigt 751 du détrompeur 750 coopérant avec la rampe 373 de l'obturateur est l'unique moyen permettant de faire tourner l'obturateur sur lui-même dans ce mode de réalisation. Ainsi, il n'est pas possible d'insérer une prise 700 standard non pourvue du détrompeur 750 dans une prise 101 selon l'invention, puisqu'il n'y a aucun élément pour permettre à l'obturateur de passer de la position fermée à la position ouverte autorisant ainsi l'accès aux contacts électriques des broches de la prise.As seen more particularly in figure 7 , the finger 751 of the polarizer 750 cooperating with the ramp 373 of the shutter is the only means for rotating the shutter on itself in this embodiment. Thus, it is not possible to insert a standard socket 700 not provided with the polarizer 750 in a socket 101 according to the invention, since there is no element to allow the shutter to pass from the closed position. in the open position thus allowing access to the electrical contacts of the pins of the socket.

Avantageusement, une telle prise 101 permet de protéger un réseau de distribution électrique de meilleure qualité d'un branchement occasionnel ou accidentel d'un appareil électrique qui n'y serait pas destiné. Le détrompeur 750 constitue en quelque sorte une clé permettant à la fiche 700 d'accéder au contact 500 de la prise 101. L'introduction et l'extraction d'une fiche pourvue d'un détrompeur 750 dans la prise 101 se déroule sensiblement de la même manière que l'introduction d'une fiche dans une prise 100 telle que décrite supra, à la différence que c'est le doigt 751 du détrompeur 750 qui transforme le mouvement du détrompeur 750 de la fiche en un mouvement de rotation de l'obturateur en fin de course afin d'ouvrir l'obturateur et permettre aux broches de la fiche 700 d'accéder au contact 500.Advantageously, such a plug 101 makes it possible to protect a better quality electrical distribution network from an occasional or accidental connection of an electrical appliance that is not intended for it. The polarizer 750 is in a way a key allowing the plug 700 to access the contact 500 of the socket 101. The introduction and extraction of a plug with a polarizer 750 in the socket 101 takes place substantially from the same way as the introduction of a plug into a socket 100 as described above, with the difference that it is the finger 751 of the polarizer 750 which transforms the movement of the polarizer 750 of the plug in a rotational movement of the shutter at the end of the race to open the shutter and allow the pins of the plug 700 to access the contact 500.

D'autres modes de réalisation pourront aisément être mis en oeuvre par l'homme du métier, en particulier des prises présentant une section ronde.Other embodiments may easily be implemented by those skilled in the art, in particular outlets having a round section.

Bien entendu, la présente invention ne se limite pas aux formes de réalisation décrites et représentées, mais englobe toute variante d'exécution.Of course, the present invention is not limited to the embodiments described and shown, but encompasses any variant embodiment.

En particulier, au lieu d'être monté mobile suivant un mouvement circulaire, l'obturateur mis en oeuvre pourrait être monté mobile suivant un mouvement linéaire.In particular, instead of being mounted mobile in a circular motion, the shutter implemented could be mounted movably in a linear motion.
