Description

L'invention concerne un dispositif de distribution de courant commandé, plus particulièrement un dispositif du genre incorporant dans un même boîtier un socle de prise de courant renfermant des plots de la prise (généralement les plots femelles), un interrupteur connecté pour commander la mise sous tension de ce socle de prise et des moyens de verrouillage mécaniques d'une fiche dans un tel socle de prise de courant.The invention relates to a controlled current distribution device, more particularly to a device of the type incorporating in the same housing a socket base containing plug pads (usually the female pads), a switch connected to control the setting under voltage of the socket base and mechanical locking means of a plug in such a socket socket.

Plus particulièrement, l'invention concerne un nouvel agencement entre ces trois sous-ensembles, plus simples et plus fiables que ceux qui sont proposés actuellement.More particularly, the invention relates to a new arrangement between these three subsets, simpler and more reliable than those currently proposed.

Pour certaines prises de courant, notamment dans le domaine des courants forts, les normes en vigueur imposent de maintenir hors tension le socle de prise de courant et d'empêcher la manoeuvre de l'interrupteur commandant sa mise sous tension tant qu'une fiche n'est pas effectivement insérée dans le socle.For some outlets, especially in the field of strong currents, the standards in force require to keep off the socket outlet and to prevent the operation of the switch controlling its power up as a record is not actually inserted in the base.

Jusqu'à présent, on a proposé différents principes de verrouillage faisant appel à divers mécanismes agencés entre l'interrupteur et le socle, permettant tout à la fois d'assujettir la manoeuvre de l'interrupteur à la présence effective d'une fiche dans le socle et de verrouiller mécaniquement celle-ci dans ledit socle, tant que celui-ci est sous tension. Les mécanismes connus font appel à des cames, glissières ou engrenages.So far, various locking principles have been proposed using various mechanisms arranged between the switch and the base, allowing at the same time to subject the operation of the switch to the actual presence of a plug in the base and mechanically lock it in said base, as long as it is powered. The known mechanisms use cams, slides or gears.

Le document DE-A-4 447 493 qui est considéré comme l'état de la technique le plus proche décrit un dispositif de courant commandé correspondant au préambule de la revendication 1.Document DE-A-4,447,493, which is considered to be the closest state of the art, describes a controlled current device corresponding to the preamble of claim 1.

L'invention propose un nouveau dispositif dans lequel le couplage entre les moyens de verrouillage de la fiche et l'interrupteur est assuré par un câble.The invention proposes a new device in which the coupling between the locking means of the plug and the switch is provided by a cable.

Plus particulièrement, l'invention concerne donc un dispositif de distribution de courant commandé du type comprenant, réunis dans un même boîtier, un socle de prise de courant et un interrupteur interconnectés électriquement pour que la mise sous tension dudit socle de prise de courant soit fonction de la position dudit interrupteur, ledit socle comportant une rainure latérale orientée dans le sens d'enfoncement d'une fiche correspondante comportant un ergot susceptible d'être engagé et de coulisser dans ladite rainure, un mécanisme de verrouillage étant agencé entre ledit interrupteur et ladite rainure pour coopérer avec un tel ergot en sorte d'assujettir la possibilité de branchement ou débranchement d'une telle fiche à une position dudit interrupteur pour laquelle ledit socle de prise de courant est hors tension, ledit mécanisme de verrouillage comportant un élément de blocage mobile le long d'un trajet transversal par rapport à ladite rainure et lui permettant de coopérer avec un tel ergot pour verrouiller une telle fiche en position et en ce que cet élément de blocage est attaché à un câble installé et guidé dans ledit boîtier, ledit câble étant couplé à un élément mobile dudit interrupteur.More particularly, the invention therefore relates to a controlled current distribution device of the type comprising, together in the same housing, a socket outlet and a switch electrically interconnected for the power of said socket outlet is function the position of said switch, said base having a lateral groove oriented in the direction of insertion of a corresponding plug comprising a lug capable of being engaged and sliding in said groove, a locking mechanism being arranged between said switch and said groove for cooperating with such lug so as to subject the possibility of connection or disconnection of such a plug to a position of said switch for which said socket base is de-energized, said locking mechanism having a locking member movable along a path transverse to said groove and allowing it to cooperate with such a pin to lock such a plug in position and that the locking member is attached to a cable installed and guided in said housing, said cable being coupled to a movable member of said switch.

Le câble est installé en boucle dans ledit chemin de guidage. Selon un mode de réalisation avantageux, le dispositif comporte un support interne s'étendant entre ledit interrupteur et ledit socle et ledit chemin de guidage est au moins en partie réalisé par une empreinte définie dans ce support. Ce dernier est fixé contre la face intérieure d'une paroi frontale du boîtier en sorte que ledit câble se trouve confiné dans un espace défini par ladite empreinte d'une part et ladite face intérieure d'autre part.The cable is looped in said guide path. According to an advantageous embodiment, the device comprises an internal support extending between said switch and said base and said guide path is at least partially formed by a footprint defined in this support. The latter is fixed against the inner face of a front wall of the housing so that said cable is confined in a space defined by said fingerprint on the one hand and said inner face on the other.

L'élément de blocage comporte une languette susceptible de coopérer avec un ergot de fiche précité. Cette languette est portée par un coulisseau installé dans une gorge rectiligne faisant partie du chemin de guidage.The locking element comprises a tab capable of cooperating with a plug lug aforesaid. This tongue is carried by a slide installed in a rectilinear groove forming part of the guide path.

La languette et le coulisseau sont rigidement liés et le montage du coulisseau dans ladite gorge rectiligne est tel que celui-ci ne puisse pivoter sur lui-même. Par conséquent, si la languette est déplacée pour venir en contact avec une extrémité d'un ergot de fiche, ladite fiche se trouve mécaniquement verrouillée dans le socle.The tongue and the slider are rigidly connected and the mounting of the slider in said straight groove is such that it can not rotate on itself. Therefore, if the tab is moved to come into contact with one end of a plug lug, said plug is mechanically locked in the socket.

Par conséquent, lorsque la languette se trouve dans une position éloignée du trajet d'un ergot de fiche matérialisé par la rainure qui se trouve définie sur le côté du socle, une telle fiche peut être connectée ou déconnectée sans difficulté. Cette position de la languette correspond à une position de l'interrupteur pour laquelle ses contacts sont ouverts et par conséquent le socle de prise de courant n'est pas sous tension.Therefore, when the tongue is in a position away from the path of a pin plug materialized by the groove which is defined on the side of the base, such a plug can be connected or disconnected without difficulty. This position of the tab corresponds to a position of the switch for which its contacts are open and therefore the base socket is not energized.

En revanche, lorsque la languette se trouve engagée dans le prolongement de la rainure latérale, une fiche préalablement connectée au socle de prise de courant s'y trouve mécaniquement verrouillée et ledit socle est sous tension.However, when the tongue is engaged in the extension of the lateral groove, a plug previously connected to the socket base is mechanically locked and said base is under tension.

Selon une autre caractéristique importante, une lamelle de verrouillage élastique est installée près de la rainure et comporte une patte située dans le prolongement de cette rainure pour être déplacée par un ergot de fiche précité. Cette lamelle comporte aussi une butée mobile conformée et positionnée pour maintenir l'élément de blocage dans une position éloignée du trajet de l'ergot de fiche défini par ladite rainure latérale. Dans cette position, l'interrupteur est ouvert et ne peut être fermé tant qu'une fiche n'est pas insérée dans le socle de prise de courant.According to another important characteristic, an elastic locking strip is installed near the groove and comprises a tab located in the groove. extension of this groove to be moved by a pin of aforementioned plug. This blade also comprises a movable abutment shaped and positioned to maintain the locking element in a position remote from the path of the plug pin defined by said lateral groove. In this position, the switch is open and can not be closed until a plug is inserted into the socket outlet.

En effet, le branchement de la fiche provoque l'effacement de la butée mobile lorsque ladite patte est déplacée par l'ergot de ladite fiche. Ce n'est donc qu'après l'effacement de la butée mobile que l'interrupteur peut être manoeuvré, c'est-à-dire fermé, la manoeuvre de l'interrupteur s'accompagnant du déplacement de la languette qui vient verrouiller la fiche dans le socle de prise de courant.Indeed, the connection of the plug causes the erasure of the movable stop when said tab is moved by the lug of said plug. It is therefore only after the deletion of the movable stop that the switch can be operated, that is to say closed, the operation of the switch accompanied by the displacement of the tongue that locks the door. plug in the socket outlet.

The invention will be better understood and other advantages thereof will appear more clearly in the light of the following description of a current distribution device according to its principle, given solely by way of example and made in reference to the accompanying drawings in which:

Le dispositif de distribution de courant 11 commandé tel que représenté comprend un boîtier 12 comportant un fond 13 destiné à être fixé à une paroi 14 et un couvercle 15 venant s'emboîter et se fixer sur un bord levé dudit fond. Le couvercle porte certains composants essentiels du dispositif, notamment un socle de prise de courant 18 et le bouton de manoeuvre rotatif 19 d'un interrupteur 20. Ce dernier est solidaire du fond 13 et monté sur des colonnettes 21 préférentiellement en matériau isolant, venues de moulage ou rapportées avec la paroi dudit fond. Ainsi, l'interrupteur se trouve quelque peu espacé de la paroi de montage dudit fond. Cet interrupteur est classique et représenté en traits fantômes pour ne pas surcharger les figures 1 et 2. Il comporte un axe de manoeuvre 24, ici à section carrée, coiffé par le bouton de manoeuvre 19 en matière plastique isolante, qui comporte un manchon tubulaire axial 26 muni d'un trou borgne 27 à section carrée dans lequel l'axe de manoeuvre de l'interrupteur est engagé à coulissement serré.The current distribution device 11 controlled as shown comprises a housing 12 having a bottom 13 intended to be fixed to a wall 14 and a cover 15 coming to fit and attach to a raised edge of said bottom. The lid carries certain essential components of the device, in particular a socket socket 18 and the rotary operating knob 19 of a switch 20. The latter is integral with the bottom 13 and mounted on columns 21, preferably made of insulating material, coming from molding or reported with the wall of said bottom. Thus, the switch is somewhat spaced from the mounting wall of said bottom. This switch is conventional and represented in phantom lines so as not to overload FIGS. 1 and 2. It comprises an operating axis 24, here at square section, capped by the operating knob 19 made of insulating plastic, which comprises an axial tubular sleeve 26 provided with a blind hole 27 of square section in which the axis of operation of the switch is engaged tightly sliding.

Par conséquent, l'axe de manoeuvre et le bouton de manoeuvre sont accouplés en rotation par l'intermédiaire de ce manchon mais peuvent être séparés axialement. Le bouton de manoeuvre comporte aussi une nervure annulaire 28 guidée en rotation contre un épaulement annulaire 29 défini tout autour d'une ouverture circulaire pratiquée à la face supérieure du couvercle 15, constituant ainsi une barrière d'étanchéité.Therefore, the operating shaft and the operating knob are coupled in rotation through this sleeve but can be axially separated. The operating knob also comprises an annular rib 28 guided in rotation against an annular shoulder 29 defined around a circular opening formed in the upper face of the cover 15, thus constituting a sealing barrier.

Le socle de prise de courant 18 est rapporté sur le couvercle et fixé à celui-ci par des vis (non représentées) ou tout autre moyen équivalent.The socket base 18 is attached to the cover and fixed thereto by screws (not shown) or any other equivalent means.

Sur les dessins, on n'a pas représenté l'embase de connexion électrique située à l'intérieur de ce socle et comportant notamment les plots femelles de la prise de courant. Les fils électriques reliant lesdits plots femelles au réseau de distribution de courant par l'intermédiaire de l'interrupteur 20 ne sont pas non plus représentés. Le socle n'apparaît que par une jupe en matière plastique isolante, cylindrique, munie extérieurement (c'est-à-dire pour la partie de la jupe qui fait saillie au-delà du couvercle du dispositif) d'une rainure latérale de détrompage 29 orientée dans le sens d'enfoncement d'une fiche correspondante. Cette jupe tubulaire permet de guider la fiche.In the drawings, there is not shown the electrical connection base located inside this base and including in particular the female studs of the plug. The electrical wires connecting said female studs to the current distribution network via the switch 20 are also not shown. The base appears only by a skirt of insulating plastic, cylindrical, provided externally (that is to say for the part of the skirt which protrudes beyond the lid of the device) a lateral keying groove 29 oriented in the direction of depression of a corresponding plug. This tubular skirt guides the plug.

La fiche 22 est classique et représentée sur la figure 1. Elle comporte également une jupe cylindrique 23 à l'intérieur de laquelle s'étendent les plots de contact mâles. La longueur de la jupe correspond à la course d'enfoncement possible de la fiche 22 à l'intérieur du socle 18. Cette jupe 23 comporte une collerette 25 ou un joint rapporté venant prendre appui contre le bord 26 de la jupe du socle, lorsque la fiche est complètement enfoncée. Il est à noter que la fiche 22 comporte un ergot de détrompage 30 susceptible d'être engagé et de coulisser dans la rainure. La longueur de cet ergot est notablement inférieure à la longueur de la jupe de la fiche sur laquelle il se trouve et il est à noter que la rainure 29 ne se prolonge pas à l'intérieur du boîtier de sorte que, lorsque la fiche est enfoncée dans le socle, ledit ergot se trouve complètement dégagé de la rainure par laquelle il a été introduit.The plug 22 is conventional and shown in Figure 1. It also comprises a cylindrical skirt 23 inside which extend the male contact pads. The length of the skirt corresponds to the possible driving stroke of the plug 22 inside the base 18. This skirt 23 has a flange 25 or an attached seal coming to bear against the edge 26 of the skirt of the base, when the plug is fully depressed. It should be noted that the plug 22 comprises a coding pin 30 that can be engaged and slide in the groove. The length of this lug is significantly less than the length of the skirt of the plug on which it is located and it should be noted that the groove 29 does not extend inside the housing so that when the plug is depressed in the base, said lug is completely clear of the groove through which it was introduced.

Comme on le verra plus loin, cette particularité permet le verrouillage mécanique de la fiche 22 dans le socle de prise 18. En effet, un mécanisme de verrouillage 34 est agencé entre l'interrupteur 20 et ladite rainure 29 pour coopérer avec un tel ergot 30 en sorte d'assujettir la possibilité de branchement ou de débranchement d'une telle fiche à une position de l'interrupteur pour laquelle le socle de prise de courant est hors tension.As will be seen below, this feature allows the mechanical locking of the plug 22 in the socket base 18. In fact, a locking mechanism 34 is arranged between the switch 20 and said groove 29 to cooperate with such a pin 30 so as to subject the possibility of connection or disconnection of such a plug to a position of the switch for which the socket outlet is de-energized.

Selon une caractéristique importante de l'invention, ce mécanisme de verrouillage 34 comporte un élément de blocage 36 mobile le long d'un trajet transversal par rapport à la rainure 29 définie sur le côté du socle et lui permettant de coopérer avec un ergot latéral 30 d'une fiche 22 pour verrouiller cette dernière en position de branchement. L'élément de blocage est attaché à un câble 39 installé dans un chemin de guidage 40 agencé dans le boîtier 12. Le câble 39 est couplé à un élément mobile de l'interrupteur, en l'occurrence ici à une partie du bouton de manoeuvre 19. Celui-ci comporte, à l'intérieur dudit boîtier, un moyeu 42 coaxial au manchon tubulaire 26 qui est accouplé en rotation à l'axe de manoeuvre 24 de l'interrupteur.According to an important feature of the invention, this locking mechanism 34 comprises a locking element 36 movable along a path transverse to the groove 29 defined on the side of the base and allowing it to cooperate with a lateral pin 30 a plug 22 to lock the latter in the connection position. The locking element is attached to a cable 39 installed in a guide path 40 arranged in the housing 12. The cable 39 is coupled to a movable element of the switch, in this case here to a portion of the operating knob 19. This includes, within the said housing, a hub 42 coaxial with the tubular sleeve 26 which is coupled in rotation to the operating shaft 24 of the switch.

Le moyeu 42 est solidaire en rotation de l'axe 24 et le câble 39 s'enroule sur le moyeu en étant rattaché à celui-ci en un point.The hub 42 is integral in rotation with the axis 24 and the cable 39 is wound on the hub by being attached thereto at one point.

Plus précisément, le câble porte une goupille 45 ou analogue qui est encastrée dans un logement 46 défini à la périphérie dudit moyeu. Le câble 39 est installé en boucle dans le chemin de guidage 40. L'élément de blocage 34 comporte une languette 49 susceptible de coopérer avec un ergot 30 de fiche et cette languette est portée par un coulisseau 50 installé dans une gorge rectiligne 40A faisant partie du chemin de guidage 40.More specifically, the cable carries a pin 45 or the like which is embedded in a housing 46 defined at the periphery of said hub. The cable 39 is installed in a loop in the guide path 40. The locking element 34 comprises a tongue 49 capable of cooperating with a pin 30 and this tongue is carried by a slide 50 installed in a straight groove 40A forming part of the guide path 40.

Selon une autre caractéristique intéressante de l'invention, le dispositif comporte un support interne 52 s'étendant entre l'interrupteur 20 (plus particulièrement l'axe de manoeuvre de celui-ci et la partie inférieure du bouton de manoeuvre) et ledit socle 18. Le chemin de guidage 40 est en partie réalisé par une empreinte définie dans ce support. Ce dernier est fixé contre la face inférieure de la paroi frontale du couvercle 15 en sorte que le câble 39 se trouve confiné dans un espace défini par l'empreinte d'une part et la face intérieure de ladite face frontale du boîtier d'autre part. L'élément de blocage 36 est monté coulissant dans le support interne 52 qui comporte la gorge rectiligne 40A précitée.According to another advantageous characteristic of the invention, the device comprises an internal support 52 extending between the switch 20 (more particularly the maneuvering axis thereof and the lower part of the operating knob) and said base 18 The guide path 40 is partly made by a footprint defined in this support. The latter is fixed against the underside of the front wall of the cover 15 so that the cable 39 is confined in a space defined by the cavity on the one hand and the inner face of said front face of the housing on the other hand . The locking element 36 is slidably mounted in the internal support 52 which comprises the straight groove 40A above.

Comme représenté sur les dessins, la paroi frontale du couvercle comporte deux parties définissant un dièdre obtus entre elles. Le bouton de manoeuvre 19 est installé sur une partie parallèle au fond du boîtier tandis que le socle 18 est installé sur une partie adjacente définissant un dièdre avec la première. Ainsi, lorsque le boîtier est monté sur une paroi verticale comme illustré à la figure 1, le socle 18 se trouve orienté en saillie vers le bas, ce qui diminue la saillie lorsqu'une prise est connectée, améliore le rayon de courbure du câble de ladite prise et évite l'accumulation de poussière ou de produit salissant, éventuellement conducteur, autour du socle de prise.As shown in the drawings, the front wall of the lid has two parts defining a dihedron obtuse them. The operating knob 19 is installed on a portion parallel to the bottom of the housing while the base 18 is installed on an adjacent portion defining a dihedron with the first. Thus, when the housing is mounted on a vertical wall as shown in Figure 1, the base 18 is oriented downwardly projecting, which decreases the projection when a plug is connected, improves the radius of curvature of the cable. said plug and avoids the accumulation of dust or dirt, possibly conductive, around the socket.

Bien entendu, le support interne 52 qui est appliqué contre la face intérieure de la paroi frontale du boîtier comporte lui-même deux parties définissant entre elles un dièdre obtus. Le support interne 52 est obtenu par moulage ou autre. Il comporte notamment des colonnettes 54 s'étendant autour de l'ouverture dans laquelle est monté le socle. Ces colonnettes reçoivent des vis auto-taraudeuses ou autres. Le socle comporte une collerette qui vient s'appliquer sur la face extérieure de la paroi frontale et les vis sont installées depuis cette collerette jusqu'aux colonnettes.Of course, the internal support 52 which is applied against the inner face of the front wall of the housing itself has two parts defining between them an obtuse dihedron. The inner support 52 is obtained by molding or the like. It comprises in particular columns 54 extending around of the opening in which the base is mounted. These columns receive self-tapping screws or other. The base comprises a collar which is applied on the outer face of the front wall and the screws are installed from this collar to the small columns.

Les deux extrémités du câble 39 sont rattachées au coulisseau 50 de part et d'autre de celui-ci, fermant ainsi la boucle. Le coulisseau 50 comporte deux crochets 56 en vis-à-vis auxquels sont respectivement rattachées les extrémités du câble. Ces dernières sont munies d'embouts élargis 57 respectivement retenus dans lesdits crochets.Both ends of the cable 39 are attached to the slider 50 on either side of it, thus closing the loop. The slider 50 comprises two hooks 56 facing each other to which the ends of the cable are respectively attached. These are provided with enlarged ends 57 respectively retained in said hooks.

En outre une lamelle de verrouillage élastique 60, par exemple en métal, est monté sur le support interne 52 au voisinage du trajet de l'élément de blocage. Cette lamelle comporte une patte 62 située dans le prolongement de la rainure latérale 29 du socle ; elle est donc susceptible d'être déplacée par un ergot de fiche 30, lorsqu'une telle fiche est insérée dans le socle. La lamelle comporte en outre une butée mobile latérale 64, conformée et positionnée pour maintenir l'élément de blocage, plus particulièrement la languette 49, dans une position éloignée du trajet de l'ergot de fiche défini par ladite rainure latérale. Cette position est illustrée sur la figure 7. Dans cette position, l'interrupteur est ouvert. En outre, une butée fixe 66 est définie sur le support interne 54 en un emplacement tel que l'élément de blocage se trouve retenu entre cette butée fixe 66 et la butée mobile 64 de la lamelle lorsqu'aucune fiche n'est connectée au socle de prise de courant.In addition, an elastic locking blade 60, for example made of metal, is mounted on the inner support 52 in the vicinity of the path of the locking element. This strip comprises a tab 62 located in the extension of the lateral groove 29 of the base; it is therefore likely to be displaced by a plug lug 30, when such a plug is inserted into the base. The strip further comprises a lateral movable stop 64, shaped and positioned to hold the blocking element, more particularly the tongue 49, in a position remote from the path of the plug pin defined by said lateral groove. This position is illustrated in Figure 7. In this position, the switch is open. In addition, a fixed stop 66 is defined on the internal support 54 at a location such that the locking element is held between this fixed stop 66 and the mobile stop 64 of the lamella when no plug is connected to the base. socket outlet.

Par conséquent, tant que le socle 18 ne reçoit pas de fiche 22, l'interrupteur est ouvert et ne peut être manoeuvré du fait que le bouton de manoeuvre 19 est immobilisé par le câble 39 et l'élément de blocage 36. En revanche, dès qu'une fiche 22 est enfoncée dans le socle de prise de courant 18, l'ergot 30 déplace la patte de la lamelle de verrouillage, ce qui a pour conséquence d'abaisser la butée mobile 64 et de libérer l'élément de blocage 36. A partir de ce moment seulement, le bouton de manoeuvre 19 peut être actionné pour fermer l'interrupteur, c'est-à-dire pour mettre le socle de prise de courant sous tension.Therefore, as the base 18 does not receive plug 22, the switch is open and can not be operated because the operating knob 19 is immobilized by the cable 39 and the locking element 36. In contrast, when a plug 22 is pressed into the socket base 18, the pin 30 moves the tab of the locking strip, which has the effect of lowering the movable stop 64 and release the blocking element 36. From this moment only, the operating button 19 can be actuated to close the switch, that is to say to put the socket outlet power.

Il est à noter que le support interne 52 est conformé pour définir une sorte de cavité autour du manchon tubulaire couplé en rotation à l'axe d'actionnement de l'interrupteur. En particulier, le moyeu 42 comporte une gorge à son extrémité qui coopère avec une nervure circulaire dudit support interne 52, constituant ainsi un encliquetage.It should be noted that the internal support 52 is shaped to define a kind of cavity around the tubular sleeve rotatably coupled to the actuating axis of the switch. In particular, the hub 42 has a groove at its end which cooperates with a circular rib of said inner support 52, thus forming a snap.

En outre, une goupille 70 est fixée transversalement à l'axe de manoeuvre de l'interrupteur et se trouve insérée entre deux prolongements 71 dudit support interne. L'axe de manoeuvre 24 s'étend entre ces deux prolongements qui définissent une fente 72 autorisant le dégagement de la goupille. La position de cette fente est telle que le démontage du couvercle 15 n'est possible que pour une position prédéterminée de l'interrupteur 20 pour laquelle son circuit électrique est ouvert.In addition, a pin 70 is fixed transversely to the operating axis of the switch and is inserted between two extensions 71 of said inner support. The operating axis 24 extends between these two extensions which define a slot 72 allowing the release of the pin. The position of this slot is such that disassembly of the cover 15 is only possible for a predetermined position of the switch 20 for which its electrical circuit is open.

Le fonctionnement du dispositif est des plus simples et découle avec évidence de la description qui précède. Le socle 18 de prise de courant plus particulièrement sa partie électrique, est raccordé au réseau par l'intermédiaire de l'interrupteur 20. Par conséquent, lorsque celui-ci est ouvert, aucune tension n'est disponible sur le socle. Compte tenu de l'agencement décrit ci-dessus, la fermeture ou l'ouverture de l'interrupteur n'est possible que si une fiche 22 est effectivement complètement enfoncée dans le socle 18 de prise de courant. De plus, la fiche ne peut être branchée ou débranchée que si la languette 49 ne se trouve pas sur le trajet de l'ergot 30, c'est-à-dire lorsque l'élément de blocage se trouve immobilisé entre lesdites butées fixe et mobile comme représenté sur la figure 7.The operation of the device is very simple and obviously follows from the foregoing description. The base 18 socket outlet, particularly its electrical part, is connected to the network via the switch 20. Therefore, when it is open, no voltage is available on the base. Given the arrangement described above, the closing or opening of the switch is possible only if a plug 22 is actually fully inserted into the base 18 socket. In addition, the plug can be connected or disconnected only if the tongue 49 is not in the path of the pin 30, that is to say when the locking element is immobilized between said fixed stops and mobile as shown in FIG. 7.

Lorsque la fiche est mise en place, la lamelle de verrouillage 60 est déplacée par l'ergot et l'interrupteur peut être manoeuvré. L'utilisateur doit alors tourner le bouton 19 pour mettre le socle de la prise sous tension en fermant l'interrupteur. Dès lors que l'interrupteur 20 est fermé, l'élément de blocage se trouve déplacé dans la position illustrée sur la figure 9 et s'oppose au retrait de la fiche 22.When the plug is put in place, the locking blade 60 is moved by the pin and the switch can be operated. The user must then turn the knob 19 to switch on the base of the plug by closing the switch. As soon as the switch 20 is closed, the blocking element is moved in the position shown in FIG. 9 and opposes the removal of the plug 22.
