On connaít déjà des documents GB 529 597, GB 536 145, GB 2 260 863, GB 2 068 651 et ES 1 046 309 un socle de prise de courant du type précité.We already know documents GB 529 597, GB 536 145, GB 2 260 863, GB 2,068,651 and US 1,046,309 a plug socket of the aforementioned type.

Selon les documents GB 2 068 651 et ES 1 046 309, le volet est déplaçable à translation entre une première et une deuxième positions sous l'action d'une broche de terre ou d'une broche d'actionnement de détrompage insérée dans le boítier isolant logeant le volet via un orifice supplémentaire prévu dans la paroi frontale de l'enjoliveur.According to the documents GB 2 068 651 and ES 1 046 309, the flap is movable in translation between first and second positions under the action an earth pin or a keying pin inserted in the insulating housing housing the flap via an additional hole provided in the front wall of the hubcap.

Selon le document GB 2 068 651, il s'agit de la broche de terre portée par la fiche insérée dans le socle de prise de courant, et, selon le document ES 1 046 309, il s'agit d'une broche d'actionnement solidaire d'un adaptateur de détrompage rapporté sur la fiche avant son insertion dans le socle de prise de courant concerné.According to GB 2 068 651, this is the earth pin carried by the plug inserted in the socket-outlet, and, according to the document ES 1 046 309, this is an actuating pin integral with an adapter of keyed on the plug before insertion into the socket socket current concerned.

Selon les documents GB 536 145, GB 529 597 et GB 2 260 863, le volet est déplaçable à rotation entre une première et une deuxième positions sous l'action d'une broche de terre insérée dans le boítier isolant logeant le volet via un orifice supplémentaire prévu dans la paroi frontale de l'enjoliveur.According to the documents GB 536 145, GB 529 597 and GB 2 260 863, the component is rotatable between first and second positions under the action of a ground pin inserted in the insulating housing housing the shutter via a additional hole provided in the front wall of the hubcap.

Ici aussi, cette broche de terre est portée par la fiche insérée dans le socle de prise de courant en question.Here too, this earth pin is carried by the plug inserted in the base outlet in question.

Selon les documents GB 536 145 et GB 2 260 863, le volet comprend trois branches s'étendant radialement à partir d'une partie centrale par laquelle il est monté à rotation, deux des trois branches recouvrant les deux éléments de contact de phase et de neutre de type femelle, la troisième recouvrant l'élément de contact de terre.According to documents GB 536 145 and GB 2 260 863, the component comprises three branches extending radially from a central part by which it is rotatably mounted, two of the three branches covering the two contact elements phase and neutral of the female type, the third covering the contact element earthen.

Les deux branches du volet recouvrant les éléments de contact de phase et de neutre de type femelle portent chacune sur une face, d'une part, une face plane qui, dans une première position du volet, est apte à se positionner en regard desdits trous pour l'obturer, et, d'autre part, une surface de came inclinée qui, dans une deuxième position du volet, est apte à se positionner en regard dudit trou pour permettre l'introduction ultérieure d'une broche de phase ou de neutre dans un des éléments de contact de type femelle par l'effacement complet des branches du volet.The two branches of the flap covering the phase contact elements and of female-type neutral each bear on one face, on the one hand, a face which, in a first position of the shutter, is able to position itself said holes to close it, and, on the other hand, an inclined cam surface which, in a second position of the flap, is able to position itself opposite said hole for allow the subsequent introduction of a phase or neutral pin into one of the female-type contact elements by completely erasing the branches of the shutter.

La troisième branche du volet comporte, sur sa face tournée vers l'orifice d'insertion de la broche de terre portée par la fiche, une surface de came inclinée permettant à ladite broche de terre de déplacer à rotation ledit volet de sa première vers sa seconde position.The third branch of the shutter comprises, on its face turned towards the orifice insertion of the earth pin carried by the plug, an inclined cam surface allowing said earth pin to rotate said shutter of its first to his second position.

Selon le document GB 529 597, le volet ne présente que deux branches dans le prolongement l'une de l'autre, de part et d'autre d'une partie centrale, qui recouvrent les éléments de contact de phase et de neutre de type femelle, et qui sont pourvues chacune, sur une face, d'une surface plane et d'une surface inclinée venant en regard desdits trous de la paroi frontale du socle, dans une première et une deuxième positions du volet. Ainsi, ici, le déplacement à rotation du volet entre ses première et deuxième positions est réalisé, via un levier d'actionnement, par la broche de terre portée par la fiche insérée dans le socle.According to the document GB 529 597, the component has only two branches in the extension of each other, on either side of a central part, which cover the female phase and neutral contact elements, and which are each provided on one side with a flat surface and an inclined surface facing said holes in the front wall of the base, in a first and a second position of the shutter. So, here, the rotating movement of the shutter between its first and second positions are realized, via an actuating lever, by the earth pin carried by the plug inserted in the base.

On connaít également du document US 4 395 082 un socle de prise de courant qui comporte deux disques rotatifs qui sont déplacés par deux rotations successives, inverses l'une de l'autre, afin d'accéder aux trous destinés à recevoir des broches de contact.Document US Pat. No. 4,395,082 also discloses a socket for current that has two rotating disks that are moved by two rotations successive, inverted from each other, in order to access the holes intended to receive contact pins.

On connaít enfin un socle de prise de courant décrit dans le document EP 1 120 862 qui comporte un volet placé entre les éléments de contact et la paroi frontale de l'enjoliveur, le volet comportant sur une face, des surfaces inclinées aptes à être positionnées en regard des trous destinés à recevoir deux broches de contact d'une fiche.Finally, we know a socket outlet described in the document EP 1 120 862 which comprises a flap placed between the contact elements and the wall front of the hubcap, the shutter having on one side inclined surfaces able to be positioned opposite the holes intended to receive two pins of contact of a card.

Le volet est déplaçable à rotation sous l'action d'une fiche portant les broches de contact.The shutter can be rotated under the action of a card carrying the contact pins.

Les socles de prise de courant précités présentent comme principal inconvénient le fait qu'ils soient non sécurisés.The above-mentioned socket-outlets present as their main disadvantage that they are insecure.

En effet, ces socles de prise de courant présentent une seule pièce, le volet, pour obturer les trous ou alvéoles d'accès aux éléments de contact. Indeed, these socket bases have a single piece, the shutter, for closing the holes or cells for access to the contact elements.

Un utilisateur peut alors toujours, à l'aide d'un outil, tel qu'un tournevis, amener le volet dans sa deuxième position de service puis le faire basculer pour accéder aux éléments de contact du socle considéré.A user can then always, using a tool, such as a screwdriver, bring the flap to its second service position and then tilt it to access the contact elements of the base in question.

Ainsi, dans un socle du type précité, malgré la présence du volet obturateur, on peut avoir accès aux éléments de contact sans introduire dans le socle une fiche mâle correspondante, ce qui n'est pas acceptable.Thus, in a base of the aforementioned type, despite the presence of the shutter shutter, the contact elements can be accessed without introducing into the base a corresponding male plug, which is not acceptable.

En outre, les socles de prise de courant précités sont des socles dits à détrompage dans lesquels il est nécessaire d'intervenir, dans un premier temps, sur l'obturateur pour amener des pentes fonctionnelles de ce dernier en face des trous de la paroi frontale de l'enjoliveur et permettre, dans un deuxième temps, l'insertion des broches actives de la fiche à l'intérieur des contacts électriques de type femelle via les orifices prévus dans la paroi frontale de l'enjoliveur.In addition, the socket-outlets mentioned above are socles known as foolproof in which it is necessary to intervene, at first, on the shutter to bring functional slopes of the latter in front of holes in the front wall of the hubcap and allow, in a second step, the insertion of the active pins of the plug inside the electrical contacts of female type via the orifices provided in the front wall of the hubcap.

Afin de résoudre les inconvénients précités de l'état de la technique, l'invention propose un socle de prise de courant selon la revendication 1.In order to solve the aforementioned drawbacks of the state of the art, the invention provides a socket outlet according to claim 1.

Ainsi, grâce à la présence de l'élément obturateur interposé entre le volet et la face arrière de l'enjoliveur, le niveau de sécurité du socle de prise de courant selon l'invention est augmenté.Thus, thanks to the presence of the shutter element interposed between the shutter and the rear face of the hubcap, the safety level of the socket outlet according to the invention is increased.

D'autres caractéristiques non limitatives et avantageuses du socle de prise de courant selon l'invention sont les suivantes :

En préliminaire, on notera que les éléments identiques ou similaires des différents socles de prise de courant représentés sur les différentes figures seront, dans la mesure du possible, référencés par les mêmes signes de référence et ne seront pas décrits à chaque fois.In preliminary, it will be noted that identical or similar elements of different socket outlets shown in the different figures will, as far as possible, be referenced by the same signs of reference and will not be described each time.

Sur les figures 1 et 5, on a représenté de façon partielle deux modes de réalisation préférentiels d'un socle 100 de prise de courant qui comporte un enjoliveur 110 pourvu, en face avant, d'un puits 111 de réception d'une fiche mâle (non représentée).In FIGS. 1 and 5, there is shown partially two modes of preferential embodiment of a base socket 100 which comprises a embellisher 110 provided, on the front face, with a well 111 for receiving a plug male (not shown).

Le fond du puits constitue la paroi frontale 112 de l'enjoliveur 110.The bottom of the well constitutes the front wall 112 of the hubcap 110.

Cette paroi frontale 112 présente deux trous (non visibles sur les figures) destinés à recevoir les deux broches de contact de la fiche (non représentée) insérée dans le socle 100.This front wall 112 has two holes (not visible in the figures) intended to receive the two contact pins of the plug (not shown) inserted into the base 100.

Cette paroi frontale 112 comporte également un autre trou 112A au travers duquel émerge une broche de raccordement à la terre non représentée.This front wall 112 also has another hole 112A at through which emerges a connection pin to the earth not shown.

Le puits 111 de l'enjoliveur 110 présente une forme cylindrique de révolution et est délimité à cet effet par une paroi cylindrique 115.The well 111 of the hubcap 110 has a cylindrical shape of revolution and is delimited for this purpose by a cylindrical wall 115.

De manière classique, le socle 100 de prise de courant comporte, à l'arrière de l'enjoliveur 110, un corps 150 en matière isolante.In a conventional manner, the socket base 100 comprises, at the back of the hubcap 110, a body 150 of insulating material.

Ce corps 150 se présente ici sous la forme d'une plaque 150A rectangulaire bordée par un trottoir qui porte, sur deux côtés opposés, des pattes 155 s'élevant perpendiculairement au plan de la plaque 150A et pourvues à leur extrémité de dents d'encliquetage 155A. Ces pattes 155 sont destinées à l'encliquetage de l'enjoliveur 110 sur le corps 150.This body 150 is here in the form of a 150A plate rectangular bordered by a sidewalk which carries, on two opposite sides, legs 155 rising perpendicular to the plane of the plate 150A and provided with their end of ratchet teeth 155A. These legs 155 are intended for the clipping of the hubcap 110 on the body 150.

A cet effet, l'enjoliveur 110 présente une face avant qui déborde de la paroi cylindrique 115 pour former un trottoir 113 de forme rectangulaire pourvu de dents d'encliquetage 113A correspondantes destinées à venir s'encliqueter sur les dents d'encliquetage 155A des pattes 155 issues du corps 150.For this purpose, the hubcap 110 has a front face that overflows the cylindrical wall 115 to form a sidewalk 113 of rectangular shape provided corresponding ratchet teeth 113A for snapping on the ratchet teeth 155A of the tabs 155 coming from the body 150.

La plaque 150A rectangulaire porte également des pattes 156 s'étendant à l'opposé des pattes 155, perpendiculairement au plan de la plaque 150A, et pourvues de dents d'encliquetage 156A pour le montage d'un boítier isolant non représenté logeant des éléments de contact de type femelle également non représentés.The rectangular plate 150A also carries legs 156 extending opposite the tabs 155, perpendicular to the plane of the plate 150A, and provided with ratchet teeth 156A for mounting a non-insulating housing represented housing female type contact elements also no represented.

Ces éléments de contact de type femelle sont positionnés dans le boítier isolant de manière à être situés en regard de trous 153 de la plaque 150A placés en regard des trous de la paroi frontale 112 de l'enjoliveur 100 rapporté sur le corps 150.These female type contact elements are positioned in the housing insulation so as to be located opposite holes 153 of the plate 150A placed facing the holes of the front wall 112 of the hubcap 100 attached to the body 150.

En outre, la plaque 150A du corps 150 porte, du même côté que les pattes 155, une paroi cylindrique 151 qui délimite, dans une partie centrale, un logement dont la paroi de fond 152 est pourvue desdits trous 153 d'accès aux éléments de contact situés sous ladite plaque 150A.In addition, the plate 150A of the body 150 carries, on the same side as the tabs 155, a cylindrical wall 151 which delimits, in a central part, a housing whose bottom wall 152 is provided with said access holes 153 to contact elements located under said plate 150A.

Ce logement, délimité par la paroi cylindrique 151, loge un système obturateur qui comporte un volet 130, positionné au-dessus des trous 153 d'accès aux éléments de contact non représentés, et déplaçable ici en rotation dans un plan parallèle au plan de la paroi de fond 152 entre différentes positions (voir figures 2A à 2C et 6A à 6C).This housing, delimited by the cylindrical wall 151, houses a system shutter which comprises a shutter 130, positioned above the holes 153 access to the contact elements not shown, and movable here in rotation in a plane parallel to the plane of the bottom wall 152 between different positions (See Figures 2A-2C and 6A-6C).

Le volet 130 comporte ici deux bras de blocage 131, 132 s'étendant dans le prolongement l'un de l'autre, de part et d'autre d'une partie centrale 133 pourvue d'un palier 133A.The shutter 130 here comprises two locking arms 131, 132 extending in the extension of one another, on either side of a central part provided with a bearing 133A.

Chaque bras de blocage 131, 132 comporte, sur une face tournée vers l'enjoliveur 110, une surface inclinée 131A, 132A.Each locking arm 131, 132 comprises, on a face turned towards the hubcap 110, an inclined surface 131A, 132A.

Les surfaces inclinées 131A, 132A du volet 130 sont orientées en sens inverse l'une de l'autre et sont aptes à être positionnées en regard des trous de l'enjoliveur 110 dans une des positions du volet 130 (voir figures 2B et 6B).The inclined surfaces 131A, 132A of the shutter 130 are oriented in the direction reverse from each other and are able to be positioned next to the holes of the hubcap 110 in one of the positions of the shutter 130 (see Figures 2B and 6B).

Le volet 130 est une pièce monobloc réalisée par exemple en matière plastique moulée.The shutter 130 is a monobloc part made for example of material molded plastic.

En outre, selon les modes de réalisation du socle de prise de courant représentés sur les figures 1 et 5, le système obturateur dudit socle 100 comporte un élément obturateur 120 ; 120' logé également dans le corps 150, et en particulier dans le logement central de ce corps 150 délimité par la paroi cylindrique 151.In addition, according to the embodiments of the socket outlet represented in FIGS. 1 and 5, the shutter system of said base 100 has a shutter element 120; 120 'also housed in the body 150, and in particular in the central housing of this body 150 delimited by the wall cylindrical 151.

Cet élément obturateur 120 ; 120' est interposé entre la face arrière 116 de la paroi frontale 112 de l'enjoliveur 110 et le volet 130 (voir figures 3 et 7). This shutter element 120; 120 'is interposed between the rear face 116 the front wall 112 of the hubcap 110 and the flap 130 (see Figures 3 and 7).

Cet élément obturateur 120 ; 120' se présente sous la forme d'un disque avec un fond circulaire 120A ; 120'A bordé par un rebord cylindrique de révolution 120B ; 120'B. Il est conformé de manière à définir intérieurement un logement cylindrique de révolution autour d'un arbre 125 ; 125' central, qui accueille le volet 130.This shutter element 120; 120 'is in the form of a disk with a circular bottom 120A; 120'A bordered by a cylindrical rim of revolution 120B; 120'B. It is shaped so as to define internally a cylindrical housing of revolution around a shaft 125; 125 'central, which welcomes shutter 130.

A cet effet, l'arbre 125 ; 125' prévu au centre de l'élément obturateur 120 ; 120' traverse le palier 133A correspondant du volet 130 et s'insère dans un orifice central 154 prévu dans le corps 150 du socle 100 de sorte que le volet 130 est apte à pivoter autour de l'arbre 125 ; 125'.For this purpose, the shaft 125; 125 'provided in the center of the shutter element 120; 120 'crosses the corresponding step 133A of the shutter 130 and fits into a central orifice 154 provided in the body 150 of the base 100 so that the flap 130 is pivotable about the shaft 125; 125 '.

Il peut ainsi notamment pivoter par rapport à l'élément obturateur 120 ; 120' pour prendre une position effacée par rapport aux trous 153 de la plaque 150A du corps 150 donnant accès aux éléments de contact de type femelle (voir figures 2C et 6C).It can thus pivot in particular with respect to the shutter element 120; 120 'to take an erased position relative to the holes 153 of the plate 150A of the body 150 giving access to the female-type contact elements (see Figures 2C and 6C).

Le fond circulaire 120A ; 120'A de l'élément obturateur 120 ; 120' vient s'appliquer contre la face arrière 116 de la paroi frontale 112 de l'enjoliveur 110 et comporte, de part et d'autre de l'arbre 125 ; 125', deux fenêtres 121, 122 ; 121', 122' donnant aux broches de contact de la fiche insérée dans le puits 111 de l'enjoliveur 110 accès auxdites surfaces inclinées 131A, 132A du volet 130.The circular bottom 120A; 120'A of the shutter member 120; 120 'is coming apply against the rear face 116 of the front wall 112 of the hubcap 110 and comprises, on both sides of the shaft 125; 125 ', two windows 121, 122; 121 ', 122' giving the contact pins of the plug inserted into the well 111 the hubcap 110 access to said inclined surfaces 131A, 132A of the shutter 130.

Selon une caractéristique essentielle du socle 100 représenté sur les figures 1 et 5, l'élément obturateur 120 ; 120' est mobile entre une première et une deuxième positions, et comporte des moyens de coopération aptes à coopérer avec une broche d'actionnement insérée dans le corps 150 du socle 100 pour faire passer ledit élément obturateur 120 ; 120' d'une première position, dans laquelle il obture les trous de la paroi frontale 112 de l'enjoliveur 110, à une deuxième position, dans laquelle les fenêtres 121, 122 ; 121', 122' sont placées au droit desdits trous de la paroi frontale 112 de l'enjoliveur 110 de façon à donner accès aux surfaces inclinées 131A, 132A du volet 130.According to an essential characteristic of the base 100 represented on the Figures 1 and 5, the shutter member 120; 120 'is movable between a first and a second position, and includes means of cooperation suitable for cooperate with an actuating pin inserted in the body 150 of the base 100 to pass said shutter member 120; 120 'of a first position, in which it closes the holes of the front wall 112 of the hubcap 110, to a second position, in which the windows 121, 122; 121 ', 122' are placed to the right of said holes of the front wall 112 of the hubcap 110 so as to give access to the inclined surfaces 131A, 132A of the shutter 130.

Ici, l'élément obturateur 120 ; 120' se déplace à rotation parallèlement au plan de la paroi de fond 152 du logement du corps 150, tout comme le volet 130. L'axe autour duquel pivotent l'élément obturateur 120 ; 120' et le volet 130 est l'axe du palier 133A du volet 130.Here, the shutter element 120; 120 'moves in rotation parallel to the plane of the bottom wall 152 of the housing of the body 150, as the flap 130. The axis around which the shutter member 120 pivots; 120 'and the shutter 130 is the axis of the bearing 133A of the flap 130.

Au surplus, le fond circulaire 120A ; 120'A de l'élément obturateur 120 ; 120' comporte une ouverture 123 ; 123' allongée, préférentiellement de forme oblongue, qui se place en correspondance du trou 112A de ladite paroi frontale 112 de l'enjoliveur 110 pour permettre à la broche de terre non représentée du socle 100 d'émerger dans le puits 111 de l'enjoliveur 110.In addition, the circular bottom 120A; 120'A of the shutter member 120; 120 'has an opening 123; 123 'elongated, preferably of shape oblong, which is placed in correspondence of the hole 112A of said front wall 112 of the hubcap 110 to allow the unrepresented ground pin of base 100 to emerge in the well 111 of the hubcap 110.

Selon le mode de réalisation du socle 100 représenté sur la figure 1, le volet 130 est monté sur l'élément obturateur 120 de manière à suivre le mouvement de ce dernier lorsqu'il est déplacé en rotation entre sa première et sa deuxième positions.According to the embodiment of the base 100 shown in FIG. shutter 130 is mounted on the shutter element 120 so as to follow the movement of the latter when it is moved in rotation between its first and his second position.

Pour ce faire, l'élément obturateur 120 porte, sur un bord de chaque fenêtre 121, 122, une paroi 124 qui s'étend perpendiculairement à partir d'une face interne dudit fond circulaire 120A dudit élément obturateur 120 de façon à fermer un espace situé au-delà de la surface inclinée 131A, 132A correspondante du volet 130.To do this, the shutter element 120 carries, on one edge of each window 121, 122, a wall 124 which extends perpendicularly from a inner face of said circular bottom 120A of said shutter member 120 so as to close a space beyond the inclined surface 131A, 132A corresponding to section 130.

Lors de la rotation de l'élément obturateur 120 entre sa première et sa deuxième positions, les parois 124 poussent le volet 130 de manière que celui-ci se déplace également en rotation simultanément à l'élément obturateur 120.During the rotation of the shutter element 120 between its first and its second positions, the walls 124 push the shutter 130 so that it also rotates simultaneously with the shutter element 120.

Selon le mode de réalisation du socle 100 représenté sur la figure 1, les moyens de coopération prévus sur l'élément obturateur 120 pour coopérer avec une broche d'actionnement insérée dans le corps 150 du socle 100 en vue de déplacer l'élément obturateur 120 entre sa première et sa deuxième positions, comprennent un pan incliné 127 débouchant dans une encoche 126 formée dans le rebord 120B périphérique de l'élément obturateur 120.According to the embodiment of the base 100 shown in FIG. means of cooperation provided on the shutter element 120 to cooperate with an actuating pin inserted in the body 150 of the base 100 in order to moving the shutter element 120 between its first and second positions, comprise an inclined pan 127 opening into a notch 126 formed in the peripheral flange 120B of the shutter element 120.

En outre, il est prévu des moyens élastiques de rappel 140, constitués ici par un ressort fil, qui sont communs à l'élément obturateur 120 et au volet 130 pour amener l'un et l'autre dans leurs positions d'origine respectives.In addition, there are provided elastic return means 140, constituted here by a wire spring, which are common to the shutter element 120 and the shutter 130 to bring the one and the other in their respective original positions.

En référence aux figures 2A à 2C, nous allons maintenant décrire le fonctionnement du système obturateur du socle 100 représenté sur la figure 1.Referring to Figures 2A-2C, we will now describe the operation of the shutter system of the base 100 shown in Figure 1.

La figure 2A montre la première position de l'élément obturateur 120 dans laquelle le fond circulaire 120A de ce dernier s'interpose entre les trous de la paroi frontale 112 de l'enjoliveur 110 en les obturant et les trous 153 de la paroi de fond 152 du logement du corps 150 au travers desquels les broches de contact d'une fiche inséré dans le socle 100 ont accès aux éléments de contact.FIG. 2A shows the first position of the shutter element 120 in which the circular bottom 120A of the latter is interposed between the holes of the front wall 112 of the hubcap 110 by closing them and the holes 153 of the bottom wall 152 of the body housing 150 through which the pins of contact of a plug inserted in the base 100 have access to the contact elements.

Comme on peut le voir sur la figure 2A, le volet 130 est positionné par rapport à l'élément obturateur 120 de sorte que les surfaces inclinées 131A, 132A des bras de blocage 131, 132 dudit volet 130 apparaissent déjà dans les fenêtres 121, 122 de l'élément obturateur 120 positionné dans sa première position.As can be seen in FIG. 2A, the shutter 130 is positioned by relative to the shutter element 120 so that the inclined surfaces 131A, 132A of the locking arms 131, 132 of said shutter 130 already appear in the windows 121, 122 of the shutter element 120 positioned in its first position.

Lorsqu'une broche d'actionnement (non représentée) est insérée dans le corps 150 du socle 100, son extrémité prend appui sur le pan incliné 127 de l'élément obturateur 120 de manière à l'entraíner en rotation dans le sens de la flèche F, c'est-à-dire dans le sens opposé aux aiguilles d'une montre.When an actuating pin (not shown) is inserted into the body 150 of the base 100, its end bears on the inclined portion 127 of the shutter element 120 so as to cause it to rotate in the direction of the arrow F, that is to say in the opposite direction of the clockwise.

De cette manière, la broche d'actionnement fait passer l'élément obturateur 120 de sa première position représentée sur la figure 2A à sa deuxième position représentée sur la figure 2B.In this way, the actuating pin passes the element shutter 120 from its first position shown in FIG. 2A at its second position shown in Figure 2B.

Cette broche d'actionnement s'engage dans un trou 153 correspondant prévu dans le corps 150 du socle 100.This actuating pin engages in a corresponding hole 153 provided in the body 150 of the base 100.

Lors de la rotation de l'élément obturateur 120 depuis sa première position (figure 2A) vers sa deuxième position (figure 2B), les parois 124 portées par celui-ci poussent le volet 130 de sorte que, simultanément au mouvement de l'élément obturateur 120, le volet 130 pivote lui aussi autour de l'arbre 125 dudit élément obturateur 120 pour suivre le mouvement de ce dernier.During the rotation of the shutter element 120 since its first position (FIG. 2A) towards its second position (FIG. 2B), the walls 124 carried by this one push the shutter 130 so that, simultaneously with the movement of the shutter element 120, the shutter 130 also pivots around the shaft 125 of said shutter element 120 to follow the movement of the latter.

Comme le montre la figure 2B, dans la deuxième position de l'élément obturateur 120, les surfaces inclinées 131A, 132A du volet 130, qui s'étendent dans les fenêtres 121, 122, se positionnent au droit des trous prévus dans la paroi frontale 112 de l'enjoliveur 110 pour l'insertion des broches de contact d'une fiche mâle dans le socle 100.As shown in Figure 2B, in the second position of the element shutter 120, the inclined surfaces 131A, 132A of the shutter 130, which extend in the windows 121, 122, are positioned to the right of the holes provided in the front wall 112 of the hubcap 110 for the insertion of the contact pins a plug in the base 100.

En outre, lors du mouvement de rotation de l'élément obturateur 120, l'ouverture 123 de forme oblongue de l'élément obturateur 120 navigue de la droite vers la gauche de part et d'autre de la broche de contact de terre (non représentée) émergeant du trou 153.In addition, during the rotational movement of the shutter element 120, the oblong-shaped aperture 123 of the shutter member 120 navigates from the right to the left on either side of the earth contact pin (no shown) emerging from hole 153.

Puis, comme le montre la figure 2C, lorsqu'une fiche mâle (non représentée) est insérée dans le puits 111 de l'enjoliveur 110, les broches de contact s'insèrent dans les trous correspondants prévus dans la paroi frontale 112 de manière à venir buter contre les surfaces inclinées 131A, 132A des bras de blocage 131, 132 du volet 130 et entraíner à rotation le volet 130 suivant la flèche F, l'élément obturateur 120 restant fixe, de manière à ce que le volet 130 s'efface sous l'élément obturateur 120 et dégage l'accès aux trous 153 prévus dans le corps 150. Les broches de contact s'engagent alors dans lesdits trous 153 dégagés pour atteindre les éléments de contact logés dans le boítier isolant porté par ledit corps 150.Then, as shown in Figure 2C, when a plug (no shown) is inserted into the well 111 of the hubcap 110, the pins of contact fit into the corresponding holes in the front wall 112 so as to abut against the inclined surfaces 131A, 132A of the arms block 131, 132 of the shutter 130 and rotate the shutter 130 according to the arrow F, the shutter element 120 remaining fixed, so that the shutter 130 disappears under the shutter element 120 and clears access to the predicted holes 153 in the body 150. The contact pins then engage in said holes 153 unobstructed to reach the contact elements housed in the insulating housing carried by said body 150.

Sur les figures 3 et 4, on a représenté deux variantes du socle 100 comprenant le système obturateur représenté sur la figure 1.In Figures 3 and 4, there is shown two variants of the base 100 comprising the shutter system shown in FIG.

Selon la variante représentée sur la figure 3, l'enjoliveur 110 comporte, dans sa paroi frontale 112, un trou supplémentaire 114 pour l'introduction à l'intérieur du corps 150 du socle 100 d'une broche d'actionnement 160 d'un adaptateur (non visible sur la figure 3) rapporté sur une fiche (non représentée) insérée dans le socle 100, les moyens de coopération, constitués ici par le pan incliné 127, de l'élément obturateur 120, étant placés en regard de ce trou supplémentaire 114 pour coopérer avec la broche d'actionnement 160 introduite à l'intérieur du socle 100 afin de faire passer l'élément obturateur 120 de sa première à sa deuxième position, comme cela est représenté sur la figure 3.According to the variant shown in FIG. 3, the hubcap 110 comprises, in its front wall 112, an additional hole 114 for the introduction to the inside of the body 150 of the base 100 of an actuating pin 160 of a adapter (not visible in Figure 3) attached to a plug (not shown) inserted in the base 100, the means of cooperation, constituted here by the pan inclined 127, of the shutter element 120, being placed opposite this hole additional 114 to cooperate with the actuating pin 160 introduced inside the base 100 in order to pass the shutter element 120 of its first to its second position, as shown in Figure 3.

Selon la variante de réalisation représentée sur la figure 4, la broche d'actionnement 117' forme avec l'enjoliveur 110' une pièce monobloc et fait saillie de la face arrière 116' de la paroi frontale 112' de l'enjoliveur 110'.According to the embodiment variant shown in FIG. 4, the spindle actuator 117 'forms with the hubcap 110' a single piece and makes protruding from the rear face 116 'of the front wall 112' of the hubcap 110 '.

Il faut comprendre par le terme "monobloc" précité que la broche d'actionnement 117' est solidarisée à l'enjoliveur 110' avant montage de celui-ci sur le corps 150 du socle 100 de prise de courant.It should be understood by the term "monoblock" above that the spindle actuating 117 'is secured to the hubcap 110' before mounting thereof on the body 150 of the socket base 100.

A cet effet, ladite broche d'actionnement 117' peut être formée d'un seul tenant avec l'enjoliveur 110', comme cela est représenté sur la figure 4, ou être rapportée sur la face arrière 116' de ce dernier par des moyens de montage appropriés.For this purpose, said actuating pin 117 'may be formed of a single holding with the hubcap 110 ', as shown in FIG. 4, or be reported on the rear face 116 'of the latter by mounting means appropriate.

La broche d'actionnement 117' est positionnée sur la face arrière 116' de la paroi frontale 112' de l'enjoliveur 110' de manière que, lors du montage de l'enjoliveur 110' sur le corps 150 du socle 100 logeant l'élément obturateur 120, elle coopère avec le pan incliné 127 de l'élément obturateur 120 afin de le faire passer de sa première position à sa deuxième position représentées sur les figures 2A et 2B.The actuating pin 117 'is positioned on the rear face 116' of the front wall 112 'of the hubcap 110' so that, during assembly of the hubcap 110 'on the body 150 of the base 100 housing the shutter element 120, it cooperates with the inclined portion 127 of the shutter element 120 in order to do so move from his first position to his second position represented on the Figures 2A and 2B.

Ainsi, avec une même partie arrière du socle 100 de prise de courant, on peut former un socle avec détrompage (voir figure 3) ou sans détrompage (voir figure 4). Thus, with the same rear part of the socket base 100, one can form a base with keying (see Figure 3) or without keying (see Figure 4).

En effet, dans la position représentée sur la figure 4 (qui correspond à la deuxième position de l'élément obturateur 120), il n'est pas besoin d'utiliser un adaptateur pour avoir accès aux éléments de contact de type femelle logés dans le socle 100, seules les broches de contact d'une fiche mâle insérée dans le puits de l'enjoliveur 110' du socle 100 coopèrent avec les surfaces inclinées 131A, 132A du volet 130 pour le déplacer et accéder auxdits éléments de type femelle dudit socle 100.Indeed, in the position shown in Figure 4 (which corresponds to the second position of the shutter element 120), there is no need to use a adapter to gain access to the female-type contact elements housed in the base 100, only the contact pins of a plug inserted into the wells of the hubcap 110 'of the base 100 cooperate with the inclined surfaces 131A, 132A of the shutter 130 to move it and access said elements of the type female said base 100.

Selon le mode de réalisation du socle 100 représenté sur la figure 5, le volet 130 est monté dans le corps 150 de manière à rester fixe au cours du déplacement à rotation de l'élément obturateur 120' entre sa première et sa deuxième positions.According to the embodiment of the base 100 shown in FIG. shutter 130 is mounted in the body 150 so as to remain fixed during the rotational movement of the shutter element 120 'between its first and its second positions.

Pour ce faire, il est prévu, sur la paroi de fond 152 du logement défini sur la plaque 150A du corps 150, deux parois 157, qui s'élèvent perpendiculairement à partir de ladite paroi de fond 152 en direction du volet 130, et qui sont positionnées de manière à former des butées contre lesquelles s'appuient les bords du volet 130 lors du déplacement de l'élément obturateur 120', depuis sa première vers sa seconde position.To do this, it is provided on the bottom wall 152 of the housing defined on the plate 150A of the body 150, two walls 157, which rise perpendicularly from said bottom wall 152 towards the flap 130, and which are positioned to form abutments against which the edges of the shutter 130 during the displacement of the shutter element 120 ', since its first to his second position.

Les deux parois 157 sont positionnées symétriquement par rapport au centre 154 de la paroi de fond 152, chacune à proximité d'un desdits trous 153 de la plaque 150A donnant accès aux éléments de contact de type femelle.The two walls 157 are positioned symmetrically with respect to the center 154 of the bottom wall 152, each near one of said holes 153 of the plate 150A giving access to the female-type contact elements.

En face de chaque paroi 157, de l'autre côté du trou 153 correspondant, il est prévu, sur la paroi de fond 152, une nervure 158 apte à coopérer avec un bras de blocage du volet 130 lorsqu'un utilisateur, pour tenter d'ouvrir le volet 130, le fait basculer selon une direction perpendiculaire au plan de rotation dudit volet 130.In front of each wall 157, on the other side of the corresponding hole 153, it is provided on the bottom wall 152, a rib 158 adapted to cooperate with a arm shutter 130 when a user, to try to open the shutter 130, makes it swing in a direction perpendicular to the plane of rotation of said shutter 130.

La coopération de la nervure 158 avec le bras de blocage 131, 132 correspondant du volet 130 empêche toute rotation éventuelle dudit volet 130 et donc tout accès non autorisé aux éléments de contact de type femelle protégés par le volet 130.The cooperation of the rib 158 with the locking arm 131, 132 corresponding shutter 130 prevents any rotation of said shutter 130 and therefore any unauthorized access to protected female contact elements by the shutter 130.

Lesdits moyens de coopération de l'élément obturateur 120' comprennent également un pan incliné 127' débouchant dans une encoche 126' formée dans le rebord 120'B périphérique de l'élément obturateur 120. Said cooperation means of the shutter element 120 ' also include an inclined pan 127 'opening into a slot 126' formed in the peripheral edge 120'B of the shutter element 120.

En outre, il est également prévu des moyens élastiques de rappel 140, constitués ici par un ressort fil, qui sont communs à l'élément obturateur 120 et au volet 130 pour amener l'un et l'autre dans leurs positions d'origine respectives.In addition, it is also provided elastic return means 140, constituted here by a wire spring, which are common to the shutter element 120 and to the shutter 130 to bring the one and the other in their original positions respectively.

En référence aux figures 6A à 6C, nous allons maintenant décrire le fonctionnement du système obturateur du socle 100 représenté sur la figure 5.Referring to Figures 6A-6C, we will now describe the operation of the shutter system of the base 100 shown in FIG.

Comme le montre la figure 6A, le volet 130 est positionné dès l'origine dans une position selon laquelle, les surfaces inclinées 131A, 132A portées par les bras de blocage 131, 132 de celui-ci sont placées en regard des trous prévus dans la paroi frontale 112 de l'enjoliveur 110 pour le passage des broches de contact d'une fiche insérée dans le puits 111 de l'enjoliveur 110.As shown in FIG. 6A, the shutter 130 is positioned from the beginning in a position that the inclined surfaces 131A, 132A carried by the locking arms 131, 132 thereof are placed opposite the holes provided in the front wall 112 of the hubcap 110 for the passage of the pins of contact of a plug inserted in the well 111 of the hubcap 110.

Par contre, dans sa première position, l'élément obturateur 120' est positionné de manière que ses fenêtres 121', 122' sont décalées par rapport aux bras de blocage 131, 132 du volet 130, et ledit élément obturateur 120' masque les surfaces inclinées 131A, 132A du volet 130 en obturant les trous prévus dans la paroi frontale 112 de l'enjoliveur 110 pour l'introduction des broches de contact d'une fiche mâle.On the other hand, in its first position, the shutter element 120 'is positioned so that its windows 121 ', 122' are offset from the locking arm 131, 132 of the shutter 130, and said shutter element 120 'mask the inclined surfaces 131A, 132A of the shutter 130 by closing the holes provided in the front wall 112 of the hubcap 110 for the introduction of the pins of contact of a plug.

Lorsqu'une broche d'actionnement est introduite dans le socle 100, elle prend appui sur le pan incliné 127' de l'élément obturateur 120' de façon à le faire pivoter suivant la flèche F' pour l'amener dans sa deuxième position, dans laquelle les fenêtres 121', 122' viennent se positionner en regard des surfaces inclinées 131A, 132A des bras de blocage 131, 132 du volet 130 (voir figure 6B) placées au droit des trous de la paroi frontale 112 de l'enjoliveur 110.When an actuating pin is inserted into the base 100, it is supported on the inclined portion 127 'of the shutter element 120' so as to rotate according to the arrow F 'to bring it to its second position, in which windows 121 ', 122' are positioned next to the surfaces inclined 131A, 132A of the locking arms 131, 132 of the shutter 130 (see FIG. 6B) placed at the right of the holes of the front wall 112 of the hubcap 110.

La broche d'actionnement navigue sur le pan incliné 127' et s'introduit dans le trou 153 correspondant du corps 150.The actuating pin navigates on the inclined pan 127 'and is introduced in the corresponding hole 153 of the body 150.

Lors du mouvement de rotation de l'élément obturateur 120', les bords des bras de blocage 131, 132 du volet 130 prennent appui contre les parois 157 portées par la paroi de fond 152 du logement défini dans le corps 150 et le volet 130 reste fixe par rapport à l'élément obturateur 120'.During the rotational movement of the shutter element 120 ', the edges locking arms 131, 132 of the shutter 130 bear against the walls 157 carried by the bottom wall 152 of the housing defined in the body 150 and the shutter 130 remains fixed with respect to the shutter element 120 '.

On remarquera que le mouvement de rotation selon la flèche F' de l'élément obturateur 120' représenté sur les figures 6A et 6B s'effectue selon un sens opposé à celui du mouvement de l'élément obturateur 120 représenté sur la figure 1, comme cela apparaít sur les figures 2A et 2B. It will be noted that the rotational movement according to the arrow F 'of the shutter element 120 'shown in FIGS. 6A and 6B is made according to a opposite direction to that of the movement of the shutter element 120 shown on Figure 1, as shown in Figures 2A and 2B.

Puis, comme le montre la figure 6C, lorsqu'une fiche mâle est insérée dans le socle 100 représenté sur la figure 5, ses broches de contact entrent en contact au travers des fenêtres 121', 122' de l'élément obturateur 120' avec les surfaces inclinées 131A, 132A du volet 130 pour l'entraíner en rotation dans le sens opposé à la flèche F', l'élément obturateur restant fixe, pour que ledit volet 130 s'efface sous l'élément obturateur 120' et libère les trous 153 de la plaque 150A du corps 150 donnant accès aux éléments de contact non représentés logés dans le boítier isolant rapporté sur ce corps 150.Then, as shown in Figure 6C, when a plug is inserted in the base 100 shown in Figure 5, its contact pins come into contact through the windows 121 ', 122' of the shutter element 120 'with the inclined surfaces 131A, 132A of the shutter 130 to cause it to rotate in the opposite direction to the arrow F ', the shutter element remaining fixed, so that said shutter 130 disappears under the shutter element 120 'and releases the holes 153 from the plate 150A of the body 150 giving access to the unrepresented contact elements housed in the insulating housing attached to this body 150.

Selon le mode de réalisation représenté sur les figures 6A à 6C, le volet 130 a donc un mouvement de rotation opposé à celui de l'élément obturateur 120' de manière à ne pas venir buter contre les parois 157 portées par le corps 150 du socle 100.According to the embodiment shown in FIGS. 6A to 6C, the shutter 130 therefore has a rotation movement opposite to that of the shutter element 120 'so as not to come up against the walls 157 carried by the body 150 of the base 100.

Ici aussi, lors du mouvement de l'élément obturateur 120' entre sa première et sa seconde positions, l'ouverture 123' oblongue navigue de la droite vers la gauche de part et d'autre de la broche de contact (non représentée) émergeant au travers du trou 153 correspondant du corps 150.Here too, during the movement of the shutter element 120 'between its first and second positions, the opening 123 'oblong navigates from the right to the left on either side of the contact pin (not shown) emerging through the corresponding hole 153 of the body 150.

Sur les figures 7 et 8, on a représenté deux variantes du socle 100 comprenant le système obturateur représenté sur la figure 5.In Figures 7 and 8, there is shown two variants of the base 100 comprising the shutter system shown in Figure 5.

Selon la variante de réalisation représentée sur la figure 7, le socle 100 est un socle à détrompage, dans lequel la paroi frontale 112 de l'enjoliveur 110 comporte un trou supplémentaire 114 pour l'introduction à l'intérieur du corps 150 d'une broche d'actionnement 160 d'un adaptateur (non représenté) rapporté sur une fiche (non représentée) insérée dans ledit socle, le pan incliné 127' de l'élément obturateur 120' étant placé en regard de ce trou supplémentaire 114 pour coopérer avec la broche d'actionnement 160 introduite à l'intérieur du corps 150 afin de faire passer l'élément obturateur 120 de sa première à sa deuxième position.According to the embodiment variant shown in FIG. 7, the base 100 is a keyed base, in which the front wall 112 of the hubcap 110 has an additional hole 114 for introduction into the body 150 of an actuating pin 160 of an adapter (not shown) reported on a plug (not shown) inserted in said base, the inclined portion 127 'of the shutter element 120 'being placed opposite this additional hole 114 to cooperate with the actuating pin 160 introduced into the body 150 to move the shutter element 120 from its first to its second position.

Lorsque la broche d'actionnement 160 de l'adaptateur n'est pas insérée dans le trou supplémentaire 114, l'élément obturateur 120' obture les trous d'accès aux éléments de contact prévus dans la paroi frontale 112 de l'enjoliveur 110.When the actuator pin 160 of the adapter is not inserted in the additional hole 114, the shutter element 120 'closes the holes access to the contact elements provided in the front wall 112 of the hubcap 110.

Selon la variante représentée sur la figure 8, le socle 100 est un socle sans détrompage, et la broche d'actionnement 117' forme avec l'enjoliveur 110' une pièce monobloc en faisant saillie de la face arrière 116' de la paroi frontale 112' de l'enjoliveur 110'.According to the variant shown in FIG. 8, the base 100 is a base without keying, and the actuating pin 117 'forms with the hubcap 110' a one-piece piece protruding from the rear face 116 'of the front wall 112 'of the hubcap 110'.

Ici aussi, on entend par le terme "monobloc" précité le fait que la broche d'actionnement 117' est solidarisée à l'enjoliveur 110' avant le montage de celui-ci sur le corps 150 du socle 100 de prise de courant.Here too, the term "monoblock" mentioned above means that the spindle actuating 117 'is secured to the hubcap 110' before assembly of it on the body 150 of the socket base 100.

A cet effet, ladite broche d'actionnement 117' peut être formée d'une seule pièce avec l'enjoliveur 110' (voir figure 8) ou être rapportée sur la face arrière 116' de ce dernier par des moyens de montage appropriés.For this purpose, said actuating pin 117 'may be formed of a single piece with the hubcap 110 '(see Figure 8) or be attached to the face rear 116 'of the latter by appropriate mounting means.

Ainsi, lorsque l'enjoliveur 110' est monté sur le corps 150 du socle 100, la broche d'actionnement 117' coopère avec le pan incliné 127' de l'élément obturateur 120' pour l'amener dans sa deuxième position (comme représenté sur la figure 8) dans laquelle, les fenêtres 121', 122' de cet élément obturateur 120' viennent se positionner au droit des surfaces inclinées 131A, 132A des bras de blocage 131, 132 du volet 130, déjà positionnées au droit des trous prévus dans la paroi frontale 112' de l'enjoliveur 110', pour l'introduction des broches de contact d'une fiche mâle insérée dans le socle 100.Thus, when the hubcap 110 'is mounted on the body 150 of the base 100, the actuating pin 117 'cooperates with the inclined portion 127' of the element shutter 120 'to bring it into its second position (as shown on FIG. 8) in which, the windows 121 ', 122' of this shutter element 120 ' are positioned at the right inclined surfaces 131A, 132A of the arms of block 131, 132 of the shutter 130, already positioned to the right of the holes provided in the front wall 112 'of the hubcap 110', for the introduction of the pins of contact of a plug inserted in the base 100.

Ainsi, une fiche mâle sans adaptateur peut être insérée dans le socle 100 et ses broches de contact coopèrent avec les surfaces inclinées 131A, 132A du volet 130 pour le déplacer et accéder aux éléments de contact positionnés sous le volet 130.Thus, a plug without adapter can be inserted in the base 100 and its contact pins cooperate with the inclined surfaces 131A, 132A of the shutter 130 to move it and access the positioned contact elements under pane 130.

Comme le montrent les figures 3 et 4 d'une part, et les figures 7 et 8 d'autre part, l'invention propose également une gamme de socles comportant la même partie arrière, c'est-à-dire le même corps 150 logeant un système obturateur, comprenant un élément obturateur 120 ; 120' et un volet 130, et deux enjoliveurs 110 ; 110' différents pour former un socle avec et sans détrompage, comme cela a été décrit précédemment. As shown in Figures 3 and 4 on the one hand, and Figures 7 and 8 on the other hand, the invention also proposes a range of pedestals comprising the same rear part, that is to say the same body 150 housing a system shutter, comprising a shutter member 120; 120 'and a flap 130, and two hubcaps 110; 110 'different to form a base with and without coding, as previously described.

En particulier, on pourra prévoir, selon une variante non représentée, que l'élément obturateur du socle selon l'invention est déplaçable en translation et que le volet est déplaçable selon un mouvement combiné de translation/rotation.In particular, it can be provided, according to a variant not shown, that the shutter element of the base according to the invention is movable in translation and that the shutter is movable according to a combined movement of translation / rotation.

On pourra également prévoir que le volet est déplaçable à translation.It can also be provided that the shutter is movable in translation.
