Description

La présente invention concerne d'une manière générale les socles de prise de courant et parmi ceux-ci les socles de prise de courant munis d'obturateurs d'alvéoles.The present invention relates generally to the bases of socket outlet and among these the socket outlets fitted cell shutters.

L'invention concerne, en particulier, un socle de prise de courant qui comprend un enjoliveur pourvu d'une paroi frontale présentant deux trous destinés à recevoir deux broches de contact d'une fiche, un corps placé à l'arrière de l'enjoliveur, qui comprend un boítier isolant logeant des éléments de contact électrique de type femelle situés en regard des deux trous de ladite paroi frontale et un obturateur positionné au-dessus desdits éléments de contact et déplaçable entre différentes positions, ledit obturateur comportant sur une face des surfaces inclinées aptes à être positionnées en regard desdits trous dans une deuxième position de l'obturateur, ainsi que des moyens de coopération aptes à coopérer avec une broche d'actionnement insérée dans ledit boítier isolant pour faire passer ledit obturateur d'une première position à sa deuxième position.The invention relates in particular to a socket outlet which includes a hubcap with a front wall having two holes intended to receive two contact pins of a plug, a body placed the rear of the hubcap, which includes an insulating housing housing elements female type electrical contact located opposite the two holes of said wall front and a shutter positioned above said contact elements and movable between different positions, said shutter comprising on one side inclined surfaces suitable for being positioned opposite said holes in a second position of the shutter, as well as means of cooperation able to cooperate with an actuating pin inserted in said housing insulator for passing said shutter from a first position to its second position.

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

Selon les documents GB 2 068 651 et ES 1 046 309, l'obturateur est déplaçable à translation entre sa première et sa deuxième position sous l'action d'une broche de terre ou d'une broche d'actionnement de détrompage insérée dans le boítier isolant logeant l'obturateur via un orifice supplémentaire prévu dans la paroi frontale de l'enjoliveur.According to documents GB 2 068 651 and ES 1 046 309, the shutter is movable in translation between its first and its second position under the action a ground pin or a keyed actuation pin inserted in the insulating housing housing the shutter via an additional orifice 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 document 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, it is an actuating pin secured to an adapter coding reported on the plug before its insertion into the socket current concerned.

Selon le document GB 2 260 863, qui est considéré comme l'état de la technique le plus proche, l'obturateur est déplaçable à rotation entre sa première et sa deuxième position sous l'action d'une broche de terre insérée dans le boítier isolant logeant l'obturateur via un orifice supplémentaire prévu dans la paroi frontale de l'enjoliveur. According to document GB 2 260 863, which is considered to be the closest state of the art, the shutter can be moved in rotation between its first and its second position under the action of an earth pin inserted in the insulating housing housing the shutter via an additional hole provided in the front wall of the hubcap.

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

Toutefois, les trois 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 ses pentes fonctionnelles 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 éléments de contact électrique de type femelle via les orifices prévus dans la paroi frontale de l'enjoliveur.However, the three aforementioned socket outlets are so-called sockets coding in which it is necessary to intervene, at first, on the shutter to bring its functional slopes in front of the holes in the front wall of the hubcap and allow, in a second step, the insertion of active pins of the plug inside the electrical contact elements of the type female via the holes provided in the front wall of the hubcap.

Par rapport à l'état de la technique précité, la présente invention propose un socle de prise de courant sans détrompage agencé de manière que le corps situé à l'arrière de l'enjoliveur de ce socle puisse être avantageusement utilisé sans modification pour réaliser un socle de prise de courant à détrompage.Compared to the aforementioned prior art, the present invention provides a socket outlet without polarization arranged so that the body located at the rear of the hub of this base can be advantageously used without modification to make a socket-outlet with polarization.

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 the identical or similar elements of the different socket outlets shown in the different figures will, as far as possible, be referenced by the same signs reference and will not be described every time.

Sur les figures 1 à 3, on a représenté de façon partielle un mode de réalisation préférentiel d'un socle 100 de prise de courant qui comprend un enjoliveur 110 pourvu, en face avant, d'un puits 111 de réception d'une fiche mâle. In Figures 1 to 3, there is shown partially a mode of preferential embodiment of a socket outlet socket 100 which includes a hubcap 110 provided, on the front face, with a well 111 for receiving a plug male.

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 113A, 113B 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 113A, 113B intended for receive the two contact pins of the plug (not shown) inserted in the base 100.

Cette paroi frontale 112 comporte également un autre trou ou alvéole 114 au travers duquel émerge une broche de raccordement à la terre non représentée.This front wall 112 also has another hole or cell 114 through which emerges a ground connection pin not represented.

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 un corps non représenté, placé à l'arrière de l'enjoliveur 110, et comprenant un boítier isolant non représenté logeant des éléments de contact électrique de type femelle, également non représentés, situés en regard des deux trous 113A, 113B de ladite paroi frontale 112.Conventionally, the socket outlet 100 has a body not shown, placed at the rear of the hubcap 110, and comprising a insulating housing not shown housing electrical contact elements of the type female, also not shown, located opposite the two holes 113A, 113B of said front wall 112.

En outre, comme le montrent les figures 1 à 3, le socle 100 de prise de courant comprend un obturateur 130 logé dans le boítier isolant non représenté, qui se positionne au-dessus des éléments de contact électrique de type femelle. Cet obturateur 130 est déplaçable entre différentes positions (voir figures 4 à 6).Furthermore, as shown in FIGS. 1 to 3, the socket 100 for taking current comprises a shutter 130 housed in the insulating housing, not shown, which is positioned above the female type electrical contact elements. This shutter 130 is movable between different positions (see Figures 4 to 6).

Selon le mode de réalisation préférentiel représenté sur les figures 1 à 3, l'obturateur 130 est monté à rotation sur une pièce support 120 fixe qui jouxte la face arrière 116 de la paroi frontale 112 de l'enjoliveur 110.According to the preferred embodiment shown in FIGS. 1 to 3, the shutter 130 is rotatably mounted on a fixed support piece 120 which adjoins the rear face 116 of the front wall 112 of the hubcap 110.

Pour ce faire, l'obturateur 130 comporte, dans une partie centrale, un palier 133 engagé sur un axe 125 porté par la partie centrale de la pièce support 120.To do this, the shutter 130 comprises, in a central part, a bearing 133 engaged on an axis 125 carried by the central part of the support part 120.

Cette pièce support 120 est conformée de manière à définir un logement cylindrique de révolution autour de l'axe 125 qui accueille l'obturateur 130.This support piece 120 is shaped so as to define a housing cylindrical of revolution around the axis 125 which receives the shutter 130.

Le fond 120A de la pièce support 120 qui vient s'appliquer contre la face arrière 116 de la paroi frontale 112 de l'enjoliveur 110 comporte, de part et d'autre de l'axe 125, deux ouvertures 121, 122 qui se placent en correspondance avec les trous 113A, 113B de ladite paroi frontale 112.The bottom 120A of the support piece 120 which is applied against the face rear 116 of the front wall 112 of the hubcap 110 comprises, on the one hand and on the other side of the axis 125, two openings 121, 122 which are placed in correspondence with the holes 113A, 113B of said front wall 112.

En outre, le fond 120A de la pièce support 120 comporte une ouverture circulaire 123 qui se place en correspondance avec le trou 114 de ladite paroi frontale 112, pour être traversée par la broche de contact de terre non représentée du socle 100 de prise de courant.In addition, the bottom 120A of the support piece 120 has an opening circular 123 which is placed in correspondence with the hole 114 of said wall frontal 112, to be crossed by the ground contact pin not shown from the socket outlet 100.

La pièce support 120 est fermée du côté opposé à l'enjoliveur 110 par une plaquette 150 de telle sorte que l'obturateur 130 est pris en sandwich entre le fond 120A de la pièce support 120 et la plaquette 150.The support piece 120 is closed on the side opposite the hubcap 110 by a wafer 150 so that the shutter 130 is sandwiched between the bottom 120A of the support piece 120 and the plate 150.

Cette plaquette 150 présente la forme d'un disque de diamètre égal au diamètre intérieur de la pièce support 120 et comporte en son centre une ouverture 153 traversée par l'axe 125 de ladite pièce support 120.This plate 150 has the shape of a disc with a diameter equal to inner diameter of the support piece 120 and has in its center a opening 153 crossed by the axis 125 of said support piece 120.

La plaquette 150 comporte, de part et d'autre de l'ouverture 153 centrale, deux autres ouvertures 151, 152 qui sont placées en correspondance avec les ouvertures 121, 122 de la pièce support 120 et les trous 113A, 113B de la paroi frontale 112 de l'enjoliveur 110.The plate 150 comprises, on either side of the central opening 153, two other openings 151, 152 which are placed in correspondence with the openings 121, 122 of the support piece 120 and the holes 113A, 113B of the wall 112 of the hubcap 110.

En outre, la plaquette 150 comporte, sur son bord périphérique, deux encoches 154, 155 positionnées de manière diamétralement opposée. L'encoche 155 se place en correspondance avec l'ouverture circulaire 123 de la pièce support 120 et le trou 114 de la paroi frontale 112 de l'enjoliveur 110, pour permettre le passage de la broche de terre dudit socle 100.In addition, the wafer 150 has, on its peripheral edge, two notches 154, 155 positioned diametrically opposite. The notch 155 is placed in correspondence with the circular opening 123 of the support piece 120 and the hole 114 of the front wall 112 of the hubcap 110, for allow the passage of the ground pin of said base 100.

Les broches de contact non représentées d'une fiche insérée dans le puits 111 de réception de l'enjoliveur 110 du socle 100 accèdent aux éléments de contact électrique de type femelle en traversant les ouvertures 121, 122 de la pièce support 120 et les ouvertures 151, 152 de la plaquette 150.Contact pins not shown on a plug inserted in the well 111 for receiving the hubcap 110 from the base 100 access the elements female type electrical contact by crossing the openings 121, 122 of the support piece 120 and the openings 151, 152 of the wafer 150.

L'épaisseur de la pièce support 120 qui accueille l'obturateur 130 est légèrement supérieure à l'épaisseur de ce dernier, de sorte qu'il y a un faible jeu entre le fond 120A et l'obturateur 130 d'une part et la plaquette 150 et l'obturateur 130 d'autre part. Ainsi, l'obturateur 130 est déplaçable à rotation autour de l'axe 125 en restant dans son plan de rotation, c'est-à-dire sans basculement dans un plan perpendiculaire.The thickness of the support piece 120 which receives the shutter 130 is slightly greater than the thickness of the latter, so that there is a slight clearance between the bottom 120A and the shutter 130 on the one hand and the wafer 150 and the shutter 130 on the other hand. Thus, the shutter 130 is rotatable around the axis 125 while remaining in its plane of rotation, that is to say without tilting in a perpendicular plane.

L'obturateur 130 comporte ici deux bras de blocage 131, 132 s'étendant dans le prolongement l'un de l'autre, de part et d'autre de la partie centrale comportant le palier 133.The shutter 130 here comprises two locking arms 131, 132 extending in the extension of each other, on either side of the central part comprising the bearing 133.

Chaque bras de blocage comporte, du côté de la face 130A de l'obturateur 130 tournée vers l'enjoliveur 110, une surface inclinée 131B, 132B et, de manière adjacente, une surface plane 131A, 132A. Each locking arm comprises, on the side of the face 130A, the shutter 130 facing the hubcap 110, an inclined surface 131B, 132B and, adjacent to it, a flat surface 131A, 132A.

Les surfaces planes 131A, 132A de l'obturateur 130 sont aptes à être positionnées en regard des ouvertures 121, 122 de la pièce support 120 et donc des trous 113A, 113B de l'enjoliveur 110 dans une première position de l'obturateur 130 qui est représentée plus particulièrement sur la figure 4.The flat surfaces 131A, 132A of the shutter 130 are able to be positioned opposite the openings 121, 122 of the support piece 120 and therefore holes 113A, 113B of the hubcap 110 in a first position of the shutter 130 which is shown more particularly in FIG. 4.

En outre, les surfaces inclinées 131B, 132B de l'obturateur 130 sont aptes à être positionnées en regard des ouvertures 121, 122 de la pièce support 120 et donc des trous 113A, 113B de l'enjoliveur 110 dans une deuxième position de l'obturateur 130 représentée plus particulièrement sur les figures 2 et 5.In addition, the inclined surfaces 131B, 132B of the shutter 130 are able to be positioned opposite the openings 121, 122 of the support piece 120 and therefore holes 113A, 113B of the hubcap 110 in a second position of the shutter 130 shown more particularly in FIGS. 2 and 5.

Dans sa première position représentée sur la figure 4, les surfaces planes 131A, 132A de l'obturateur 130 forment des surfaces de butée pour des broches de contact d'une fiche insérée dans le puits 111 de réception de l'enjoliveur 110 et, de ce fait, l'obturateur 130 empêche auxdites broches de contact d'accéder aux éléments de contact électrique de type femelle du socle 100 de prise de courant.In its first position shown in Figure 4, the surfaces planes 131A, 132A of the shutter 130 form abutment surfaces for contact pins of a plug inserted in the well 111 for receiving the cover 110 and, as a result, the shutter 130 prevents said pins from contact to access the female type electrical contact elements of the base 100 of power outlet.

Dans la deuxième position représentée sur les figures 2 et 5, l'obturateur 130 est en position d'attente de broches de contact d'une fiche à insérer dans le socle 100 de prise de courant. La mise en appui des broches de contact d'une fiche sur les surfaces inclinées 131B, 132B de l'obturateur 130 provoque la rotation de celui-ci dans le sens des aiguilles d'une montre matérialisée par la flèche F, de sorte qu'il se place en dehors desdits trous 113A, 113B de l'enjoliveur (voir figure 6). Il permet ainsi l'insertion desdites broches de contact dans le corps du socle 100 de prise de courant et leur mise en contact avec les éléments de contact électrique de type femelle dudit socle 100.In the second position shown in Figures 2 and 5, the shutter 130 is in the waiting position for contact pins of a plug to be inserted in the socket outlet 100. Pressing the contact pins of a plug on the inclined surfaces 131B, 132B of the shutter 130 causes the rotation of it clockwise, materialized by the arrow F, so that it is placed outside said holes 113A, 113B of the hubcap (see Figure 6). It thus allows the insertion of said contact pins in the body of the socket outlet socket 100 and their contact with the female type electrical contact elements of said base 100.

Pour déplacer l'obturateur 130 de sa première à sa deuxième position, celui-ci comporte des moyens de coopération aptes à coopérer avec une broche d'actionnement 117 réalisée en matière non conductrice insérée dans le boítier isolant non représenté du corps du socle 100 de prise de courant.To move the shutter 130 from its first to its second position, this includes cooperation means capable of cooperating with a spindle actuator 117 made of non-conductive material inserted in the housing insulator not shown from the body of the socket outlet socket 100.

Ici, ces moyens de coopération de l'obturateur 130 comprennent un bras d'actionnement 134 qui est positionné entre ses deux bras de blocage 131, 132 et qui s'étend à partir de la partie centrale de l'obturateur 130 selon une direction radiale. Here, these means of cooperation of the shutter 130 comprise an arm actuator 134 which is positioned between its two locking arms 131, 132 and which extends from the central part of the shutter 130 in a direction radial.

Ce bras d'actionnement 134 porte, sur sa face tournée vers l'enjoliveur 110, une surface de came 134A apte à coopérer avec la broche d'actionnement 117 pour engendrer un mouvement de rotation de l'obturateur 130 entre sa première position et sa deuxième position représentées sur les figures 4 et 5.This actuating arm 134 carries, on its face facing the hubcap 110, a cam surface 134A capable of cooperating with the actuating pin 117 to generate a rotational movement of the shutter 130 between its first position and its second position shown in FIGS. 4 and 5.

Selon une caractéristique particulièrement avantageuse du socle 100 de prise de courant représenté sur les figures 1 à 3, la broche d'actionnement 117 forme avec l'enjoliveur 110 une pièce monobloc et fait saillie de la face arrière 116 de ladite paroi frontale 112 de l'enjoliveur 110.According to a particularly advantageous characteristic of the base 100 of socket outlet shown in Figures 1 to 3, the actuating pin 117 forms with the hubcap 110 a single piece and protrudes from the rear face 116 of said front wall 112 of the hubcap 110.

Ici, la broche d'actionnement 117 est d'un seul tenant avec l'enjoliveur 110, mais en variante on pourrait prévoir qu'elle soit rapportée sur la face arrière de l'enjoliveur par des moyens de montage appropriés.Here, the actuating pin 117 is in one piece with the hubcap 110, but as a variant, provision could be made for it to be attached to the rear face of the hubcap by suitable mounting means.

Ainsi, une fois assemblé, le socle 100 de prise de courant représenté sur les figures 1 à 3 comporte un obturateur 130 d'alvéoles et constitue un socle de prise de courant sans détrompage dans lequel une fiche sans détrompeur peut être insérée.Thus, once assembled, the socket outlet socket 100 shown on Figures 1 to 3 comprises a shutter 130 of cells and constitutes a base of non-polarized socket outlet in which a non-polarized plug can be inserted.

En effet, l'obturateur 130 est positionné dans sa première position dans le logement défini par la pièce support 120 et fermé par la plaquette 150. L'ensemble des trois éléments précités est monté sur le boítier isolant non représenté logeant les éléments de contact électrique de type femelle du socle 100. La pièce support 120 comporte à cet effet des pattes d'encliquetage 127 qui font saillie d'un trottoir 126. Le boítier isolant supportant ladite pièce support 120 forme un bloc ou corps autonome du socle 100 prêt à recevoir un enjoliveur et, en particulier, l'enjoliveur 110.Indeed, the shutter 130 is positioned in its first position in the housing defined by the support piece 120 and closed by the plate 150. All of the aforementioned three elements are mounted on the non-insulating housing. shown housing the female type electrical contact elements of the base 100. The support piece 120 for this purpose includes latching lugs 127 which protrude from a sidewalk 126. The insulating housing supporting said support piece 120 forms an autonomous block or body of the base 100 ready to receive a hubcap and, in particular, the hubcap 110.

Lors du montage de l'enjoliveur 110 sur le corps du socle 100, la broche d'actionnement 117 portée par celui-ci coopère avec la surface de came 134A du bras d'actionnement 134 de l'obturateur 130 afin de le faire passer de sa première position à sa deuxième position représentée sur les figures 2 et 5. Dans cette deuxième position, les surfaces inclinées 131B, 132B portées par les bras de blocage 131, 132 de l'obturateur 130 sont positionnées en regard des ouvertures 121, 122 de la pièce support 120 et des trous 113A, 113B de la paroi frontale 112 de l'enjoliveur 110.When mounting the hubcap 110 on the body of the base 100, the spindle actuator 117 carried by the latter cooperates with the cam surface 134A the actuating arm 134 of the shutter 130 in order to pass it from its first position to its second position shown in Figures 2 and 5. In this second position, the inclined surfaces 131B, 132B carried by the locking arm 131, 132 of the shutter 130 are positioned opposite the openings 121, 122 of the support piece 120 and holes 113A, 113B of the wall 112 of the hubcap 110.

Lorsque, ultérieurement, une fiche est insérée dans le socle 100 de prise de courant, les broches de contact de la fiche prennent appui sur lesdites surfaces inclinées 131B, 132B de l'obturateur 130 pour faire passer celui-ci de sa deuxième position vers sa troisième position représentée sur la figure 6 et accéder aux éléments de contact électrique de type femelle logés dans le boítier isolant du socle 100 en dessous dudit obturateur 130.When, later, a plug is inserted into the socket 100 of current, the contact pins of the plug bear on said inclined surfaces 131B, 132B of the shutter 130 for passing it from its second position towards its third position shown in FIG. 6 and access the female type electrical contact elements housed in the housing insulator of the base 100 below said shutter 130.

Avantageusement, les contours 121A, 122A des ouvertures 121, 122 prévues dans le fond 120A de la pièce support 120 épousent le contour 131C, 132C des bras de blocage 131, 132 de l'obturateur 130.Advantageously, the contours 121A, 122A of the openings 121, 122 provided in the bottom 120A of the support piece 120 conform to the outline 131C, 132C of the locking arms 131, 132 of the shutter 130.

De cette manière, lorsque l'obturateur 130 est positionné dans sa deuxième position, prêt à être actionné en rotation par lesdites broches de contact d'une fiche, et qu'un utilisateur tente d'avoir accès aux éléments de contact électrique de type femelle dudit socle 100 situés sous l'obturateur 130 au moyen d'un instrument quelconque tel qu'un tournevis en prenant appui sur l'un des bras de blocage 131, 132 de l'obturateur 130 pour le faire basculer, l'autre bras de blocage 131, 132 de l'obturateur 130 s'engage dans l'ouverture 121, 122 correspondante de la pièce support 120 et se bloque contre le champ de cette ouverture.In this way, when the shutter 130 is positioned in its second position, ready to be actuated in rotation by said pins contact of a file, and that a user tries to have access to the elements of female type electrical contact of said base 100 located under the shutter 130 at using any instrument such as a screwdriver by pressing on one locking arms 131, 132 of the shutter 130 to make it tilt, the other locking arm 131, 132 of the shutter 130 engages in the opening 121, 122 support piece 120 and hangs against the field of this opening.

La coopération d'un des bras de blocage 131, 132 de l'obturateur 130 avec le champ d'une des ouvertures 121, 122 de la pièce support 120 empêche toute rotation de celui-ci et, de ce fait, empêche l'accès aux éléments de contact électrique de type femelle du socle 100, ce qui répond aux exigences normatives.The cooperation of one of the locking arms 131, 132 of the shutter 130 with the field of one of the openings 121, 122 of the support piece 120 prevents any rotation thereof and thereby prevents access to the contact elements female type electrical socket 100, which meets the requirements Normative.

En fait, pour pouvoir se déplacer à rotation, l'obturateur 130 doit rester dans sa position d'assiette dans laquelle les bras de blocage 131, 132 s'étendent au même niveau.In fact, to be able to move in rotation, the shutter 130 must remain in its position of attitude in which the locking arms 131, 132 extend at the same level.

Comme le montrent plus particulièrement les figures 1 et 3, la pièce support 120 comporte sur un bord une encoche 124 au travers de laquelle émerge l'extrémité du bras d'actionnement 134 de l'obturateur 130 pour être accessible à la broche d'actionnement 117. Une encoche 154 de la plaquette 150 est placée en correspondance de l'encoche 124 de la pièce support 120.As shown more particularly in Figures 1 and 3, the part support 120 has on one edge a notch 124 through which emerges from the end of the actuating arm 134 of the shutter 130 to be accessible to the actuating pin 117. A notch 154 in the plate 150 is placed in correspondence with the notch 124 of the support piece 120.

En outre, l'obturateur 130 est rappelé depuis sa troisième position représentée sur la figure 6 dans sa deuxième position où il obture les ouvertures 121, 122 de la pièce support 120 et les trous 113A, 113B de la paroi frontale 112 de l'enjoliveur 110 par un moyen élastique de rappel constitué ici par un ressort 140 de rappel enroulé autour du palier 133 de l'obturateur 130 et qui prend appui sur la plaquette 150.In addition, the shutter 130 is recalled from its third position shown in Figure 6 in its second position where it closes the openings 121, 122 of the support piece 120 and the holes 113A, 113B of the front wall 112 of the hubcap 110 by an elastic return means constituted here by a spring 140 return wound around the bearing 133 of the shutter 130 and which is supported on the wafer 150.

Avantageusement, le socle 100 décrit précédemment en référence aux figures 1 à 6 fait partie d'une gamme de socles de prise de courant qui comporte un deuxième socle 100' représenté plus particulièrement sur les figures 7 et 9 à 11. Ce deuxième socle 100' comporte un corps identique à celui du premier socle 100 ainsi qu'un enjoliveur 110' pourvu d'une paroi frontale 112' présentant deux trous 113'A, 113'B destinés à recevoir deux broches de contact 201, 202 d'une fiche 200, un trou 114' pour le passage de la broche de terre non représentée et un trou supplémentaire 114" pour l'introduction à l'intérieur dudit boítier isolant non représenté d'une broche d'actionnement 164 d'un adaptateur 160 rapporté sur la fiche 200 à insérer dans le deuxième socle 100'.Advantageously, the base 100 described above with reference to Figures 1 to 6 is part of a range of socket outlets which includes a second base 100 'shown more particularly in Figures 7 and 9 to 11. This second base 100 'has a body identical to that of the first base 100 and a cover 110 'provided with a front wall 112' having two holes 113'A, 113'B intended to receive two contact pins 201, 202 a plug 200, a hole 114 'for the passage of the ground pin not shown and an additional hole 114 "for the introduction inside said insulating housing not shown with an actuating pin 164 of an adapter 160 attached to the plug 200 to be inserted in the second base 100 '.

En fait, la gamme de socles de prise de courant comporte un premier socle 100 sans détrompage et un deuxième socle 100' à détrompage, les premier et deuxième socles 100, 100' comportant des corps identiques renfermant un obturateur 130 identique, la différence essentielle se situant au niveau de l'enjoliveur puisque, dans le cas du premier socle 100, l'enjoliveur 110 porte sur sa face arrière 116 la broche d'actionnement 117 de l'obturateur 130, alors que, dans le cas du deuxième socle 100', l'enjoliveur 110' est tout à fait classique dont la face arrière 116' de la paroi frontale 112' ne porte aucune saillie, la broche d'actionnement 164 faisant partie d'un adaptateur 160 rapporté sur la fiche 200 insérée dans le deuxième socle 100'.In fact, the range of socket outlets includes a first base 100 without polarization and a second base 100 'with polarization, the first and second bases 100, 100 'having identical bodies containing an identical shutter 130, the essential difference being at level of the hubcap since, in the case of the first base 100, the hubcap 110 carries on its rear face 116 the actuating pin 117 of the shutter 130, whereas, in the case of the second base 100 ', the trim 110' is entirely conventional, the rear face 116 ′ of the front wall 112 ′ having no projection, the actuating pin 164 being part of an adapter 160 attached on the plug 200 inserted in the second base 100 '.

Dans le deuxième socle 100' de prise de courant, les moyens de coopération de l'obturateur 130 constitués ici par le bras d'actionnement 134 portant la surface de came 134A sont placés en regard du trou supplémentaire 114" prévu dans la paroi frontale 112' de l'enjoliveur 110' de sorte qu'ils coopèrent avec la broche d'actionnement 164 introduite dans ledit socle 100' afin de faire passer ledit obturateur 130 de sa première position telle que représentée sur les figures 4 et 9 à sa deuxième position telle que représentée sur les figures 5, 10 et 11.In the second socket outlet 100 ', the means of shutter cooperation 130 formed here by the actuating arm 134 bearing the cam surface 134A are placed opposite the additional hole 114 "provided in the front wall 112 'of the hubcap 110' so that they cooperate with the actuating pin 164 introduced into said base 100 'so to move said shutter 130 from its first position as shown in Figures 4 and 9 in its second position as shown in the figures 5, 10 and 11.

De manière classique, l'adaptateur 160 est constitué par une plaquette qui est percée de trois trous, à savoir deux trous 161, 162 dans lesquels viennent s'engager les broches de contact 201, 202 de la fiche 200 lorsque la plaquette est rapportée sur la face externe de cette fiche 200 et un troisième trou 163 qui vient se placer en correspondance avec le trou prévu dans la fiche pour l'insertion de la broche de terre non représentée.Conventionally, the adapter 160 consists of a plate which is pierced with three holes, namely two holes 161, 162 in which engage the contact pins 201, 202 of the plug 200 when the plate is attached to the external face of this plug 200 and a third hole 163 which is placed in correspondence with the hole provided in the card for the insertion of the ground pin not shown.

Comme le montre mieux la figure 8, lorsque l'adaptateur 160 est positionné sur la fiche 200, celle-ci comporte donc trois broches, deux broches de contact 201, 202 et la broche d'actionnement 164 en matériau non-conducteur permettant l'actionnement de l'obturateur 130 de manière classique.As best shown in Figure 8, when the adapter 160 is positioned on the plug 200, it therefore has three pins, two pins contact 201, 202 and the actuating pin 164 of non-conductive material allowing actuation of the shutter 130 in a conventional manner.

Les premier et deuxième socles 100, 100' peuvent être réalisés facilement, puisque le corps de ces socles est identique et seul l'enjoliveur est différent.The first and second bases 100, 100 'can be produced easily, since the body of these bases is identical and only the hubcap is different.

Ainsi, on peut choisir, en fin de chaíne de montage, de rapporter un enjoliveur 110 à broche d'actionnement 117 ou un enjoliveur 110 sans broche d'actionnement pour réaliser à partir d'un même corps un socle sans détrompage ou avec détrompage.So, we can choose, at the end of the assembly line, to bring a cover 110 with actuating pin 117 or cover 110 without pin of actuation to realize from the same body a base without coding or with keying.

De plus, un installateur ou un utilisateur peut configurer le socle de prise de courant, au moment souhaité. Il peut aussi modifier facilement la configuration choisie.In addition, an installer or a user can configure the socket-outlet of current, at the desired time. It can also easily change the configuration chosen.

La présente invention n'est nullement limitée au mode de réalisation décrit et représenté, mais l'homme du métier saura y apporter toute variante conforme à son esprit.The present invention is in no way limited to the embodiment described and represented, but the person skilled in the art will know how to make any variant conforms to his spirit.

En particulier, on pourrait prévoir que l'obturateur du socle de prise de courant selon l'invention soit déplaçable à translation ou selon un mouvement combiné translation/rotation à l'intérieur du corps du socle.In particular, provision could be made for the shutter of the socket outlet current according to the invention either movable in translation or according to a movement combined translation / rotation inside the base body.

Dans le cas où l'obturateur du socle de prise de courant selon l'invention est déplaçable à translation, lesdites surfaces inclinées portées par lesdits bras de blocage de l'obturateur sont orientées dans le même sens.In the case where the shutter of the socket outlet according to the invention is movable in translation, said inclined surfaces carried by said arms shutter locks are oriented in the same direction.

En outre, le bras d'actionnement de l'obturateur peut comporter des moyens de pivotement pour pouvoir basculer sous l'action dudit bras d'actionnement entre deux positions, à savoir une position de verrouillage dans laquelle ledit bras d'actionnement est en butée contre un bord de la pièce support fixe interposée entre la paroi frontale de l'enjoliveur et ledit obturateur, et une position de déverrouillage dans laquelle ledit bras d'actionnement est dégagé du bord de ladite pièce support. In addition, the shutter actuation arm may include pivoting means to be able to tilt under the action of said arm actuation between two positions, namely a locking position in which said actuating arm abuts against an edge of the workpiece fixed support interposed between the front wall of the hubcap and said obturator, and an unlocking position in which said actuating arm is clear of the edge of said support piece.

Ces moyens de pivotement peuvent comprendre une charnière d'articulation reliant la broche d'actionnement à la partie centrale de l'obturateur qui peut être une liaison souple venant de formation avec celui-ci, ou qui peut comprendre un pivot situé sur une face du bras d'actionnement tournée à l'opposé de l'enjoliveur.These pivoting means may include a hinge hinge connecting the actuating pin to the central part of the shutter which can be a flexible bond coming from formation with this one, or which can include a pivot located on one side of the actuating arm turned to the opposite of the hubcap.

Selon ce mode de réalisation, rien n'empêche cependant que le bras d'actionnement porte, sur la face tournée vers l'enjoliveur, une surface de came qui coopère avec la broche d'actionnement introduite dans le corps du socle de prise de courant.According to this embodiment, however, nothing prevents the arm actuation door, on the face facing the hubcap, a cam surface which cooperates with the actuating pin introduced into the body of the base plug.

Selon une autre variante non représentée, on pourrait prévoir que le bras d'actionnement de l'obturateur porte, à la place de la surface de came, sur sa face tournée vers l'enjoliveur, un pan incliné apte à coopérer avec ladite broche d'actionnement.According to another variant not shown, it could be provided that the arm actuator of the shutter door, instead of the cam surface, on its face turned towards the hubcap, an inclined face able to cooperate with said spindle actuating.

Lorsque l'obturateur présente un mouvement combiné translation/rotation, on peut également prévoir que ladite broche d'actionnement présente, à son extrémité libre, une rampe qui coopère avec le bras d'actionnement de l'obturateur pour ramener l'obturateur dans sa deuxième position depuis sa troisième position dans laquelle il est positionné en dehors desdits trous de l'enjoliveur.When the shutter has a combined movement translation / rotation, it is also possible to provide that said actuating pin has a ramp at its free end which cooperates with the arm shutter actuation to return the shutter to its second position from its third position in which it is positioned outside said holes in the hubcap.

Enfin, selon une autre variante non représentée, on pourrait prévoir de réaliser l'obturateur en deux pièces distinctes qui s'emboítent l'une dans l'autre, présentant dans une partie centrale un palier commun pour la coopération de l'obturateur avec l'axe d'entraínement en rotation de celui-ci, une des deux pièces, à savoir la première pièce, portant lesdites surfaces planes aptes à être positionnées en regard desdits trous de la paroi frontale de l'enjoliveur, dans la première position de l'obturateur, et l'autre des deux pièces, la seconde pièce, portant lesdites surfaces inclinées qui, dans ladite première position de l'obturateur, sont masquées par ladite première pièce du fait de l'emboítement des première et seconde pièces, ladite première pièce étant déplaçable entre la première position et la deuxième position de l'obturateur pour dégager lesdites surfaces inclinées de l'obturateur de sorte qu'elles se positionnent en regard desdits trous de l'enjoliveur.Finally, according to another variant not shown, provision could be made for make the shutter in two separate pieces which fit into each other, presenting in a central part a common landing for the cooperation of the shutter with the rotary drive axis thereof, one of two parts, namely the first part, carrying said flat surfaces capable of being positioned opposite said holes in the front wall of the hubcap, in the first position of the shutter, and the other of the two parts, the second part, carrying said inclined surfaces which, in said first position of the shutter, are masked by said first part due to the nesting first and second parts, said first part being movable between the first position and the second position of the shutter to release said inclined shutter surfaces so that they face each other said holes in the hubcap.
