Description

La présente invention concerne de manière générale le domaine des appareillages électriques connectés et notamment celui des prises de courant connectées.The present invention relates generally to the field of connected electrical equipment and in particular that of connected sockets.

Elle concerne plus particulièrement une prise de courant connectée au standard Schuko® destinée à être montée dans une boîte d'encastrement comprenant un boîtier fermé à l'avant par un enjoliveur formant un puits d'insertion d'une fiche électrique, avec une paroi de fond percée d'orifices d'accès à des bornes de connexion électrique de phase et de neutre disposées dans le boîtier, ledit boîtier renfermant une borne de connexion de terre ainsi qu'une carte électronique percée d'une ouverture circulaire à un endroit excentré par rapport au centre de la paroi de fond du puits d'insertion.It relates more particularly to a socket connected to the Schuko® standard intended to be mounted in a flush-mounting box comprising a box closed at the front by a cover forming an insertion hole for an electrical plug, with a wall of base pierced with access holes to phase and neutral electrical connection terminals arranged in the box, said box containing an earth connection terminal and an electronic card pierced with a circular opening at a location eccentric by relative to the center of the bottom wall of the insertion well.

Les appareillages électriques connectés comprennent des éléments électroniques permettant notamment d'assurer la commande de leur mise en service à distance à l'aide d'un appareil portable. Ces éléments électroniques sont raccordés à un circuit imprimé dont la plaque support est montée dans le socle du mécanisme d'appareillage.Connected electrical equipment comprises electronic elements making it possible in particular to control their commissioning remotely using a portable device. These electronic elements are connected to a printed circuit, the support plate of which is mounted in the base of the switchgear mechanism.

Actuellement, le volume interne disponible dans le socle du mécanisme d'appareillage est limité car ce dernier présente des dimensions standardisées. Ainsi, tous les éléments du mécanisme d'appareillage doivent être agencés de manière à occuper un volume maximal autorisé par le volume interne disponible dans le socle.Currently, the internal volume available in the base of the fitting mechanism is limited because the latter has standardized dimensions. Thus, all the elements of the fitting mechanism must be arranged so as to occupy a maximum volume authorized by the internal volume available in the base.

En particulier, dans le cas d'une prise de courant au standard Schuko® (standard germanique correspondant aux normes DIN49441 et DIN49440), un dispositif de sécurité et une lyre conductrice permettant la mise à la terre sont montés dans le socle, occupant une grande partie du volume interne disponible. En pratique, la base centrale de la lyre conductrice est positionnée entre la cassette du dispositif de sécurité et les logements accueillant les bornes électriques.In particular, in the case of a Schuko® standard socket outlet (Germanic standard corresponding to DIN49441 and DIN49440 standards), a safety device and a conductive bracket allowing earthing are mounted in the base, occupying a large part of the internal volume available. In practice, the central base of the conductive lyre is positioned between the cassette of the safety device and the housings accommodating the electrical terminals.

Dans le cas d'une prise de courant connectée au standard Schuko®, la plaque support comprenant le circuit imprimé (formant une carte électronique) doit également être ajoutée dans le socle. Deux configurations sont alors possibles pour l'implantation de la carte électronique. La première consiste à augmenter le volume interne disponible dans le socle. Dans ce cas, la fabrication d'un socle aux dimensions personnalisées est nécessaire.In the case of a socket connected to the Schuko® standard, the support plate including the printed circuit (forming an electronic card) must also be added to the base. Two configurations are then possible for the installation of the electronic card. The first is to increase the internal volume available in the plinth. In this case, the manufacture of a base with personalized dimensions is necessary.

Selon la deuxième configuration, la carte électronique devrait être positionnée à l'emplacement occupé par la lyre conductrice afin de satisfaire au volume interne disponible dans le socle. L'implantation simultanée de la lyre conductrice et de la carte électronique dans le socle du mécanisme d'appareillage est alors incompatible avec les dimensions standardisées de celui-ci.According to the second configuration, the electronic card should be positioned at the location occupied by the conducting lyre in order to satisfy the internal volume available in the base. The simultaneous implantation of the conductive lyre and of the electronic card in the base of the fitting mechanism is then incompatible with the standardized dimensions thereof.

Le but de la présente invention est donc de proposer une prise de courant connectée au standard Schuko® dans laquelle la mise en place de la carte électronique et de la lyre conductrice dans le socle du mécanisme d'appareillage est compatible avec le volume interne disponible d'un socle aux dimensions standardisées.The aim of the present invention is therefore to provide a socket outlet connected to the Schuko® standard in which the placement of the electronic card and of the conducting lyre in the base of the fitting mechanism is compatible with the available internal volume of '' a base with standardized dimensions.

Plus particulièrement, on propose selon l'invention une prise de courant connectée au standard Schuko® destinée à être montée dans une boîte d'encastrement conforme à la revendication 1.More particularly, according to the invention there is proposed a socket outlet connected to the Schuko® standard intended to be mounted in a flush-mounting box according to claim 1.

Ainsi, avantageusement selon l'invention, l'entretoise conductrice est adaptée pour permettre de positionner la lyre conductrice en dehors du volume interne du socle du mécanisme d'appareillage tout en assurant la connexion entre la lyre conductrice et la borne de connexion de terre. La carte électronique peut alors être positionnée dans le socle sans avoir besoin d'augmenter son volume interne. De plus, avantageusement, dans la prise de courant conforme à l'invention, la carte électronique utilisée est une carte standard généralement implantée dans des prises de courant au standard franco-belge (correspondant à la norme NF C61-314) avec une broche de connexion à la terre, et l'entretoise conductrice traverse l'ouverture circulaire de cette carte électronique prévue pour le passage de cette broche de terre, afin d'établir la connexion électrique entre la lyre conductrice de mise à la terre et la borne de connexion de terre. Ainsi, de manière avantageuse, une même carte électronique peut être utilisée pour les prises de courant au standard Schuko® et dans les prises de courant au standard franco-belge.Thus, advantageously according to the invention, the conductive spacer is adapted to make it possible to position the conductive lyre outside the internal volume of the base of the fitting mechanism while ensuring the connection between the conductive lyre and the earth connection terminal. The electronic card can then be positioned in the base without needing to increase its internal volume. In addition, advantageously, in the socket in accordance with the invention, the electronic card used is a standard card generally installed in sockets of the Franco-Belgian standard (corresponding to the NF C61-314 standard) with a pin of connection to the earth, and the conductive spacer passes through the circular opening of this electronic card provided for the passage of this earth pin, in order to establish the electrical connection between the conductive earthing bracket and the connection terminal earthen. Thus, advantageously, the same electronic card can be used for the Schuko® standard sockets and for the Franco-Belgian standard sockets.

D'autres caractéristiques non limitatives et avantageuses de la prise de courant conforme à l'invention, prises individuellement ou selon toutes les combinaisons techniquement possibles, sont décrites dans les revendications 2 à 14.Other non-limiting and advantageous characteristics of the socket outlet according to the invention, taken individually or in any technically possible combination, are described in claims 2 to 14.

Les figures 1 à 5 représentent une prise de courant 10 connectée selon le standard Schuko®.The figures 1 to 5 represent a socket 10 connected according to the Schuko® standard.

La prise de courant 10 représentée sur les figures 1 et 2, comprend un moteur pourvu d'un socle 100 logeant des éléments électriques et/ou électroniques, un support d'appareillage 400, et un enjoliveur 200 (qui donne la fonction à l'appareillage). La prise de courant 10 est destinée à être montée dans une boîte d'encastrement (non représentée).The socket 10 shown on the figures 1 and 2 , comprises a motor provided with a base 100 housing electrical and / or electronic elements, an equipment support 400, and a cover 200 (which gives the function to the equipment). The socket 10 is intended to be mounted in a flush-mounting box (not shown).

Le socle 100 comprend un boîtier ou une enveloppe 110 en matière isolante. Cette enveloppe 110 est généralement réalisée d'une seule pièce en matière plastique moulée.The base 100 comprises a casing or an envelope 110 made of insulating material. This envelope 110 is generally made from a single piece of molded plastic.

L'enveloppe 110 qui forme le boîtier, présente une forme globalement parallélépipédique ouverte à l'avant.The envelope 110 which forms the housing has a generally parallelepipedal shape open at the front.

Elle comporte une paroi de fond 111 à partir de laquelle s'élève une paroi latérale 112.It has a bottom wall 111 from which rises a side wall 112.

La paroi latérale 112 est constituée de quatre panneaux 112A, 112B deux à deux parallèles, reliés par quatre pans coupés 112C placés aux quatre coins du parallélépipède. La paroi latérale 112 présente un bord avant 115 libre périphérique qui délimite l'ouverture avant de l'enveloppe 110.The side wall 112 consists of four panels 112A, 112B two by two parallel, connected by four cut sides 112C placed at the four corners of the parallelepiped. The side wall 112 has a peripheral free front edge 115 which delimits the front opening of the casing 110.

La face externe SE de l'enveloppe 110 délimite un volume d'encombrement hors tout du socle 100, tandis que la face interne SI de cette enveloppe 110 délimite un logement de réception des divers éléments électriques et électroniques.The outer face SE of the casing 110 defines an overall overall volume of the base 100, while the internal face SI of this casing 110 defines a housing for receiving the various electrical and electronic elements.

Au fond du logement de réception, il est prévu des espaces de montage de trois bornes de connexion électrique, une borne de connexion de terre 141 et deux bornes de connexion de phase et de neutre (non représentées). En pratique, les bornes de connexion électrique sont par exemple clipsées dans des chambres isolées d'un boîtier intermédiaire 136 placé au fond du logement de réception de ladite enveloppe 110. Par exemple, la borne de connexion de terre 141 est clipsée dans la chambre 142 du boîtier intermédiaire 136 (figure 2). Ce boîtier intermédiaire 136 est par exemple ici rapporté sur la face arrière d'une plaque support de circuit imprimé 130, lesdites bornes étant soudées au circuit imprimé 130.At the bottom of the receiving housing, spaces are provided for mounting three electrical connection terminals, one earth connection terminal 141 and two phase and neutral connection terminals (not shown). In practice, the electrical connection terminals are for example clipped into isolated chambers of an intermediate housing 136 placed at the bottom of the housing for receiving said casing 110. For example, the earth connection terminal 141 is clipped into the chamber 142. of the intermediate box 136 ( figure 2 ). This intermediate housing 136 is for example attached here to the rear face of a printed circuit support plate 130, said terminals being welded to the printed circuit 130.

Les bornes de connexion électrique sont par exemple des bornes automatiques à lame ressort de contact et il est prévu dans un des panneaux 112B de la paroi latérale 112 de l'enveloppe 110, à proximité de la paroi de fond 111, des ouvertures 111B dans lesquelles sont engagées des poussettes 120 aptes à agir sur les lames ressorts de contact desdites bornes pour la déconnexion des conducteurs électriques. Afin d'établir une connexion électrique entre chaque borne de connexion électrique et les poussettes 120, chaque chambre isolée du boîtier intermédiaire 136 accueillant les bornes de connexion électrique est munie d'une fente (figure 2). Chaque fente, par exemple la fente 142A de la chambre 142 de la borne de connexion de terre 141, permet donc le raccordement entre une borne de connexion électrique et une poussette parmi les poussettes 120 par l'intermédiaire de languettes dont est munie chaque poussette. Par exemple, la languette 120A de l'une des poussettes 120 est engagée dans l'une des ouvertures 111B puis dans la fente 142A de la chambre 142 afin d'agir sur la lame ressort de la borne de connexion de terre 141.The electrical connection terminals are for example automatic terminals with a contact spring blade and it is provided in one of the panels 112B of the side wall 112 of the casing 110, near the bottom wall 111, openings 111B in which are engaged strollers 120 capable of acting on the contact spring blades of said terminals for the disconnection of the electrical conductors. In order to establish an electrical connection between each electrical connection terminal and the strollers 120, each insulated chamber of the intermediate box 136 accommodating the electrical connection terminals is provided with a slot ( figure 2 ). Each slot, for example the slot 142A of the chamber 142 of the earth connection terminal 141, therefore allows the connection between an electrical connection terminal and a stroller among the strollers 120 by means of tabs with which each stroller is provided. For example, the tongue 120A of one of the strollers 120 is engaged in one of the openings 111B then in the slot 142A of the chamber 142 in order to act on the leaf spring of the earth connection terminal 141.

En outre, il est prévu dans la paroi de fond 111, des ouvertures 111C d'accès aux espaces de montage desdites bornes électriques pour l'introduction de l'âme conductrice dénudée des conducteurs électriques dans lesdites bornes électriques. Classiquement, comme cela est visible sur la figure 2, il est prévu deux ouvertures 111C par borne électrique de sorte que, dans chaque borne, il est possible de connecter un conducteur provenant du réseau électrique et un conducteur de repiquage.In addition, there are provided in the bottom wall 111, openings 111C for access to the mounting spaces of said electrical terminals for the introduction of the conductive core stripped of the electrical conductors into said electrical terminals. Conventionally, as can be seen on the figure 2 , two openings 111C are provided per electrical terminal so that, in each terminal, it is possible to connect a conductor from the electrical network and a transplanting conductor.

L'enveloppe 110 du socle 100 comporte au milieu de deux panneaux 112A parallèles, une cheminée 116 qui débouche, à l'avant, dans une encoche du panneau 112A, et, à l'arrière, dans un logement 116A prévu en renfoncement de la face externe SE. Chaque cheminée 116 est destinée à accueillir une vis de griffe 116B dont la griffe 116C se loge dans ledit logement 116A. Les deux vis de griffe 116B servent à l'accrochage du socle 100 dans la boîte d'encastrement (non représentée) via les griffes 116C (figures 1 et 2). Ces griffes 116C vont venir se mettre en prise avec des éléments correspondants de la boîte d'encastrement (non représentée) lorsqu'une vis de griffe 116B sera vissée au travers d'un orifice 116D de la griffe 116C.The casing 110 of the base 100 comprises in the middle of two parallel panels 112A, a chimney 116 which opens, at the front, into a notch of the panel 112A, and, at the rear, into a housing 116A provided in the recess of the external face SE. Each chimney 116 is intended to accommodate a claw screw 116B whose claw 116C is housed in said housing 116A. The two claw screws 116B are used to hook the base 100 into the flush-mounting box (not shown) via the claws 116C ( figures 1 and 2 ). These claws 116C will come into engagement with corresponding elements of the mounting box (not shown) when a claw screw 116B is screwed through a hole 116D of the claw 116C.

Selon le mode de réalisation de l'invention représenté sur les figures 1 à 5, le support d'appareillage 400 est constitué d'une seule pièce isolante, un cadre 410 réalisé en matière plastique moulée dans lequel peut être noyée une âme métallique de renfort. Il peut également être prévu, à la place de l'âme métallique, selon une variante non représentée, des plaquettes métalliques de renfort noyées dans la matière plastique au niveau des ouvertures de fixation du cadre 410.According to the embodiment of the invention shown in figures 1 to 5 , the equipment support 400 consists of a single insulating part, a frame 410 made of molded plastic material in which a reinforcing metal core can be embedded. There may also be provided, instead of the metal core, according to a variant not shown, reinforcing metal plates embedded in the plastic material at the level of the fixing openings of the frame 410.

Ici, le cadre 410 du support d'appareillage 400, représenté sur les différentes figures, présente un contour carré aux coins arrondis et sa tranche périphérique externe 411 comporte quatre parties droites deux à deux parallèles.Here, the frame 410 of the appliance support 400, shown in the various figures, has a square outline with rounded corners and its outer peripheral edge 411 comprises four straight parts two by two parallel.

La tranche périphérique interne 412 du cadre 410 suit le contour d'une sorte de polygone (voir figures 1 et 2) avec quatre parties droites, parallèles aux parties droites de la tranche périphérique externe 411, reliées par quatre parties en arc de cercle.The internal peripheral slice 412 of the frame 410 follows the contour of a sort of polygon (see figures 1 and 2 ) with four straight parts, parallel to the straight parts of the outer peripheral edge 411, connected by four parts in an arc of a circle.

Le cadre 410 du support d'appareillage 400 comporte quatre ouvertures 414, en forme de trou serrure, réparties régulièrement sur un cercle autour de son ouverture centrale 413, dans des régions situées entre les parties droites des tranches périphériques interne 411 et externe 412. Ces ouvertures 414 servent au passage de vis pour le vissage éventuel du support d'appareillage 400 dans des fûts taraudés de la boîte d'encastrement (non représentée).The frame 410 of the appliance support 400 has four openings 414, in the form of a keyhole, distributed regularly in a circle around its central opening 413, in regions located between the straight parts of the inner 411 and outer 412 peripheral edges. openings 414 are used for the passage of screws for the possible screwing of the device support 400 in the threaded barrels of the flush-mounting box (not shown).

Le cadre 410 comporte une épaisseur définie entre, d'une part, un plan arrière 410B d'appui du support d'appareillage 400 contre une paroi de montage (ici non représentée) et, d'autre part, une face avant 410A destinée à être recouverte d'au moins un élément de finition (non représenté).The frame 410 has a thickness defined between, on the one hand, a rear plane 410B for supporting the appliance support 400 against a mounting wall (here not shown) and, on the other hand, a front face 410A intended for be covered with at least one finishing element (not shown).

Plus particulièrement, comme le montre la figure 2, le cadre 410 du support d'appareillage 400 comporte une face arrière plane 410B qui s'étend dans un plan P et qui forme ledit plan arrière d'appui sur une paroi de montage.More particularly, as shown in figure 2 , the frame 410 of the appliance support 400 comprises a flat rear face 410B which extends in a plane P and which forms said rear bearing plane on a mounting wall.

L'élément de finition est généralement une plaque de finition qui recouvre la face avant 410A du cadre 410 du support d'appareillage 400 et qui s'étend au-delà dudit cadre 410 sur la paroi de montage pour parfaire l'esthétique de l'ensemble. Elle est encliquetée dans des ouvertures 417 du cadre 410 prévues à cet effet.The finishing element is generally a finishing plate which covers the front face 410A of the frame 410 of the appliance support 400 and which extends beyond said frame 410 on the mounting wall to improve the aesthetics of the appliance. together. It is snapped into openings 417 of the frame 410 provided for this purpose.

La solidarisation du socle 100 audit support d'appareillage 400 est réalisée au moyen d'éléments de fixation 500 qui s'étendent au travers de ladite épaisseur du cadre 410.The base 100 is secured to said appliance support 400 by means of fixing elements 500 which extend through said thickness of the frame 410.

Lesdits éléments de fixation 500 sont contenus dans un volume limité à l'arrière du support d'appareillage 400 par ledit plan arrière 410B si bien qu'aucune saillie n'est formée à l'arrière dudit support d'appareillage 400 au-delà dudit plan arrière 410B. Ici, lesdits éléments de fixation 500 sont entièrement logés dans ladite épaisseur cadre 410. Les éléments de fixation 500 sont rapportés sur ledit support d'appareillage 400 et sur ledit socle 100.Said fixing elements 500 are contained in a volume limited to the rear of the appliance support 400 by said rear plane 410B so that no projection is formed at the rear of said appliance support 400 beyond said said plane. rear plane 410B. Here, said fixing elements 500 are entirely housed in said frame thickness 410. The fixing elements 500 are attached to said equipment support 400 and to said base 100.

De façon préférentielle, les éléments de fixation 500 sont des rivets traversant ledit support d'appareillage 400 et une partie 117 dudit socle 100. Il est prévu quatre rivets 500 disposés sur le cercle intercalés entre les ouvertures 414 en forme de trou de serrure. Ces rivets 500 sont avantageusement réalisés en laiton.Preferably, the fixing elements 500 are rivets passing through said appliance support 400 and a part 117 of said base 100. Four rivets 500 are provided, arranged on the circle interposed between the openings 414 in the form of a keyhole. These rivets 500 are advantageously made of brass.

Comme le montrent les figures 1 et 2, l'enveloppe 110 isolante du socle 100 comporte un bord avant 115 qui délimite l'ouverture avant dudit socle, et des languettes 117 qui s'étendent à partir dudit bord avant 115 vers l'extérieur dudit socle 100. Il est prévu ici quatre languettes 117 placées aux quatre coins de l'enveloppe 110 du socle 100. Ces languettes 117 présentent une forme en triangle. Elles sont chacune percée d'un orifice 118 cylindrique qui débouche sur la face arrière de la languette 117 par un élargissement formant une gorge 119 (voir figure 2).As the figures 1 and 2 , the insulating casing 110 of the base 100 comprises a front edge 115 which delimits the front opening of said base, and tabs 117 which extend from said front edge 115 towards the outside of said base 100. There are provided here four tabs 117 placed at the four corners of the casing 110 of the base 100. These tabs 117 have a triangle shape. They are each pierced with a cylindrical orifice 118 which opens onto the rear face of the tongue 117 by an enlargement forming a groove 119 (see figure 2 ).

Lesdits éléments de fixation 500 coopèrent avec lesdites languettes 117 de l'enveloppe 110 du socle 100 pour assurer la solidarisation du socle 100 au support d'appareillage 400.Said fixing elements 500 cooperate with said tongues 117 of the casing 110 of the base 100 to ensure the attachment of the base 100 to the appliance support 400.

Selon une caractéristique préférentielle de l'appareillage électrique 10, le support d'appareillage 400 et le socle 100 comprennent des éléments de positionnement complémentaires, distincts desdits éléments de fixation 500, qui coopèrent ensemble en des lieux situés à l'intérieur dudit volume d'encombrement hors tout dudit socle 100.According to a preferred characteristic of the electrical equipment 10, the equipment support 400 and the base 100 comprise complementary positioning elements, distinct from said fixing elements 500, which cooperate together at places located inside said volume of overall size of said base 100.

Comme le montre la figure 2, les éléments de positionnement comprennent, d'une part, sur ledit support d'appareillage 400, une paroi 415 prévue à l'arrière du cadre 410, qui s'étend perpendiculairement audit plan arrière 410B à l'intérieur dudit socle 100, et qui porte au moins une dent d'accrochage 415A, et, d'autre part, sur ledit socle 100, au moins une fenêtre 114 formée dans ladite enveloppe 110, présentant un bord sur lequel s'accroche ladite dent d'accrochage 415A.As shown in the figure 2 , the positioning elements comprise, on the one hand, on said equipment support 400, a wall 415 provided at the rear of the frame 410, which extends perpendicularly to said rear plane 410B inside said base 100, and which carries at least one hooking tooth 415A, and, on the other hand, on said base 100, at least one window 114 formed in said envelope 110, having an edge on which said hooking tooth 415A hooks.

Elle comporte deux parties droites diamétralement opposées dont les faces tournées à l'opposée de l'ouverture centrale 413 du support d'appareillage, portent chacune une telle dent d'accrochage 415A. En correspondance, deux panneaux 112B parallèles de la paroi latérale 112 de l'enveloppe 110 du socle 100 comportent deux fenêtres 114 pour l'accrochage desdites dents d'accrochage 415A.Here, the wall 415 is a peripheral wall provided at the rear of the frame 410 and which runs along the edge of the central opening 413 of the appliance support 400. It comprises two diametrically opposed straight parts, the faces of which face opposite directions. of the central opening 413 of the device support, each carry such a fastening tooth 415A. Correspondingly, two parallel panels 112B of the side wall 112 of the casing 110 of the base 100 comprise two windows 114 for the attachment of said attachment teeth 415A.

La paroi 415 comporte au milieu de deux autres parties droites diamétralement opposées, deux cheminées 416 qui débouchent chacune dans une encoche semi-cylindrique 416A, pour le passage des vis de griffe 116B en vue de la fixation du support d'appareillage 400 et du socle 100 fixé audit support à la paroi d'une boîte d'encastrement.The wall 415 comprises in the middle of two other diametrically opposed straight parts, two chimneys 416 which each open into a semi-cylindrical notch 416A, for the passage of the claw screws 116B for the fixing of the appliance support 400 and the base. 100 fixed to said support to the wall of a flush-mounting box.

Comme le montrent les figures 1 et 2, en dessous de l'enjoliveur 200, le socle 100 loge les bornes de connexion électrique de terre, de phase et de neutre. Il loge les poussettes de déconnexion 120. Il loge également une plaque support de circuit imprimé 130 dont les pistes sont connectées à des éléments électroniques nécessaires pour connecter la prise de courant 10 à un dispositif de commande portable (non représenté) ou déporté (tel qu'un dispositif de commande sans fil lié à un réseau de communication de données de type Internet). L'ensemble formé par la plaque support de circuit imprimé 130 et les éléments électroniques montés sur cette plaque support de circuit imprimé 130 définit une carte électronique 135.As the figures 1 and 2 , below the cover 200, the base 100 houses the electrical connection terminals for earth, phase and neutral. It houses the disconnection strollers 120. It also houses a printed circuit support plate 130 whose tracks are connected to electronic elements necessary to connect the socket 10 to a portable (not shown) or remote control device (such as 'a wireless control device linked to an Internet-type data communication network). The assembly formed by the support plate printed circuit 130 and the electronic elements mounted on this printed circuit support plate 130 defines an electronic card 135.

Comme cela est représenté sur la figure 1, la carte électronique 135 est percée de trois ouvertures 137A, 137B de forme circulaire. En pratique, ces ouvertures circulaires sont percées au niveau de la plaque support du circuit imprimé 130 qui ne comporte par d'éléments électroniques.As shown in the figure 1 , the electronic card 135 is pierced with three openings 137A, 137B of circular shape. In practice, these circular openings are drilled at the level of the support plate of the printed circuit 130 which does not include any electronic elements.

Parmi les trois ouvertures, deux ouvertures 137A donnent accès aux bornes de connexion électrique de phase et de neutre placées à l'intérieur du socle 100. La troisième ouverture circulaire 137B est située à un endroit excentré par rapport au centre de la carte électronique et elle permet l'accès à la borne de connexion de terre 141 placée également à l'intérieur du socle 100.Among the three openings, two openings 137A give access to the phase and neutral electrical connection terminals placed inside the base 100. The third circular opening 137B is located at a location eccentric with respect to the center of the electronic card and it allows access to the earth connection terminal 141 also placed inside the base 100.

Ici, avantageusement, selon l'invention, la carte électronique 135 est une carte électronique usuellement utilisée dans une prise de courant connectée au standard franco-belge avec une broche de terre qui traverse ladite troisième ouverture circulaire 137B de la carte électronique 135. La troisième ouverture circulaire 137B est donc positionnée à l'endroit où est usuellement placé l'orifice de passage d'une broche de terre d'une prise de courant au standard franco-belge.Here, advantageously, according to the invention, the electronic card 135 is an electronic card usually used in a socket connected to the Franco-Belgian standard with an earth pin which passes through said third circular opening 137B of the electronic card 135. The third circular opening 137B is therefore positioned at the place where the passage opening for an earth pin of a Franco-Belgian standard socket is usually placed.

Plus précisément, la troisième ouverture circulaire 137B de la carte électronique 135 présente une section sensiblement égale à celle d'une broche de terre d'une prise de courant au standard franco-belge. Cette troisième ouverture circulaire 137B présente par exemple un diamètre compris entre 4,2 et 5,4 millimètres. Ces caractéristiques présentent donc un avantage industriel certain car une même carte électronique peut être utilisée, à la fois, pour les prises de courant au standard franco-belge et pour les prises de courant au standard Schuko® selon l'invention.More precisely, the third circular opening 137B of the electronic card 135 has a section substantially equal to that of an earth pin of a socket outlet to the Franco-Belgian standard. This third circular opening 137B has for example a diameter of between 4.2 and 5.4 millimeters. These characteristics therefore have a definite industrial advantage because the same electronic card can be used both for the sockets of the Franco-Belgian standard and for the sockets of the Schuko® standard according to the invention.

Parmi les éléments électroniques, il est prévu un relais 131 qui présente un fort encombrement. Ce relais 131 de forme parallélépipédique rectangle s'étend jusqu'au fond du socle 100 où il occupe un espace libre supplémentaire donné par une ouverture rectangulaire 111A prévue dans la paroi de fond 111 de l'enveloppe 110 du socle 100. Il est également prévu une antenne 132 qui s'élève à partir de la face avant de la plaque support de circuit imprimé 130 (voir figure 1). Cette antenne 132 s'engage dans un aménagement prévu sur la surface extérieure de la paroi latérale 210 de l'enjoliveur 200 où elle est protégée. De cette manière, l'antenne 132 peut arriver jusqu'à la façade la prise de courant 10.Among the electronic elements, a relay 131 is provided which is very bulky. This relay 131 of rectangular parallelepiped shape extends to the bottom of the base 100 where it occupies an additional free space given by a rectangular opening 111A provided in the bottom wall 111 of the casing 110 of the base 100. It is also provided. an antenna 132 which rises from the front face of the printed circuit support plate 130 (see figure 1 ). This antenna 132 engages in an arrangement provided on the outer surface of the side wall 210 of the cover 200 where it is protected. In this way, the antenna 132 can reach the front of the socket 10.

La prise de courant 10, ici une prise de courant connectée, comporte un enjoliveur 200 de prise de courant formé d'une plaque de base 230 dont la face avant 230A porte une paroi latérale, ici cylindrique, 210 avec un bord libre 213. La paroi latérale 210 délimite latéralement un puits d'insertion d'une fiche électrique (non représentée). La paroi de fond 220 du puits d'insertion est formée par une partie de la plaque de base 230. Elle est percée de deux orifices 221 (figures 2 et 3) donnant accès aux bornes de connexion électrique de phase et de neutre placées à l'intérieur du socle 100. Les deux orifices 221 sont disposés en regard des ouvertures 137A de la carte électronique 135.The socket 10, here a connected socket, comprises a socket cover 200 formed by a base plate 230 whose front face 230A carries a side wall, here cylindrical, 210 with a free edge 213. The side wall 210 laterally delimits a well for inserting an electrical plug (not shown). The bottom wall 220 of the insertion well is formed by a part of the base plate 230. It is pierced with two holes 221 ( figures 2 and 3 ) providing access to the phase and neutral electrical connection terminals placed inside the base 100. The two orifices 221 are placed opposite the openings 137A of the electronic card 135.

Ces deux orifices 221 sont par exemple de forme circulaire avec un diamètre compris entre 5,2 et 5,8 mm. En notant O1 et O2 leurs centres (figure 2), ces deux orifices 221 sont disposés ici de manière à ce que le milieu du segment [O102] coïncide avec le centre O de la paroi de fond 220 du puits d'insertion. La distance entre les centres O1 et O2 des deux orifices 221 est par exemple ici comprise entre 18,6 et 19,4 mm.These two orifices 221 are for example circular in shape with a diameter of between 5.2 and 5.8 mm. By noting O1 and O2 their centers ( figure 2 ), these two orifices 221 are arranged here so that the middle of the segment [O102] coincides with the center O of the bottom wall 220 of the insertion well. The distance between the centers O1 and O2 of the two orifices 221 is for example here between 18.6 and 19.4 mm.

Comme le montre la figure 1, la paroi latérale 210 comporte sur sa face externe un renflement 234. Ce renflement 234 s'étend sur toute la hauteur de la paroi latérale 210. Il est creusé d'un conduit fermé à l'extrémité située du côté dudit bord libre 213, à l'avant de la prise de courant 10, et qui débouche sur la face arrière 230B de la plaque de base 230. Ce conduit du renflement 234 correspond à l'aménagement précédemment décrit et prévu sur la surface extérieure de la paroi latérale 210 de l'enjoliveur 220 pour loger et protéger l'antenne 132.As shown in the figure 1 , the side wall 210 has a bulge 234 on its outer face. This bulge 234 extends over the entire height of the side wall 210. It is hollowed out with a closed duct at the end located on the side of said free edge 213, at the front of the socket 10, and which opens onto the rear face 230B of the base plate 230. This duct of the bulge 234 corresponds to the arrangement previously described and provided on the outer surface of the side wall 210 of the trim 220 to house and protect the antenna 132.

La plaque de base 230 porte, sur sa tranche 231, des dents 233 pour l'accrochage de l'enjoliveur 200 au socle 100. Les dents 233 s'accrochent sur le bord de fenêtres 113 prévues dans les panneaux 112A parallèles de la paroi latérale 112 de l'enveloppe 110 du socle 100.The base plate 230 carries, on its edge 231, teeth 233 for hooking the cover 200 to the base 100. The teeth 233 hook on the edge of windows 113 provided in the parallel panels 112A of the side wall 112 of the casing 110 of the base 100.

Lorsque l'enjoliveur 200 est accroché au socle 100 et que le socle 100 est solidarisé au support d'appareillage 400, la paroi latérale 210 de l'enjoliveur 200, dont le diamètre externe est égal au jeu près au diamètre interne de l'ouverture centrale 413 du support d'appareillage 400, émerge au travers de ladite ouverture centrale 413 du support d'appareillage 400 pour s'élever au-dessus de la face avant 410A du cadre 410 (voir figures 3 et 4).When the cover 200 is hooked to the base 100 and the base 100 is secured to the equipment support 400, the side wall 210 of the cover 200, the external diameter of which is equal to the clearance close to the internal diameter of the opening 413 of the device support 400, emerges through said central opening 413 of the device support 400 to rise above the front face 410A of the frame 410 (see figures 3 and 4 ).

Comme le montre la figure 2, la plaque de base 230 porte sur sa face arrière 230B, des brides 232 pour l'accrochage d'une cassette 310 d'un dispositif de sécurité 300 qui ferme les orifices 221 de la paroi de fond 220du puits d'insertion de l'enjoliveur 200 pour interdire l'accès aux bornes de connexion électrique de phase et de neutre de la prise de courant à tout autre élément que les broches d'une fiche électrique engagée dans le puits d'insertion de la prise de courant.As shown in the figure 2 , the base plate 230 carries on its rear face 230B, flanges 232 for the attachment of a cassette 310 of a safety device 300 which closes the orifices 221 of the bottom wall 220 of the insertion well of the trim 200 to prevent access to the phase and neutral electrical connection terminals of the outlet to any element other than the pins of an electrical plug engaged in the insertion well of the outlet.

La cassette 310 du dispositif de sécurité comporte sur la face externe de sa paroi latérale 311, des dents 313 prévues pour l'accrochage auxdites brides 232 de la plaque de base 230.The cassette 310 of the safety device comprises on the outer face of its side wall 311, teeth 313 provided for hooking to said flanges 232 of the base plate 230.

Ce dispositif de sécurité 300 comporte un élément de fermeture 320 monté à pivotement à l'intérieur de la cassette 310. L'élément de fermeture 320 comporte deux volets 320A à surfaces inclinées, qui s'étendent de part et d'autre d'une partie centrale montée à pivotement sur un axe prévu au centre de la cassette 310.This safety device 300 includes a closure member 320 pivotally mounted inside the cassette 310. The closure member 320 has two flaps 320A with surfaces. inclined, which extend on either side of a central part pivotally mounted on an axis provided at the center of the cassette 310.

La paroi de fond 312 de la cassette 310 est percée de trois ouvertures 312A, 312B (figure 2) dont deux ouvertures 312A d'accès aux bornes de connexion électrique de phase et de neutre de la prise de courant et une ouverture 312B d'accès à la borne de connexion de terre. Les trois ouvertures 312A, 312B de la paroi de fond 312 de la cassette 310 sont placées en regard des ouvertures 137A, 137B de la carte électronique 135. Les ouvertures 312A de la paroi de fond 312 de la cassette 310 sont disposées en regard des orifices 221 de la paroi de fond 220 du puits d'insertion.The bottom wall 312 of the cassette 310 is pierced with three openings 312A, 312B ( figure 2 ) including two openings 312A for access to the phase and neutral electrical connection terminals of the power outlet and one opening 312B for access to the earth connection terminal. The three openings 312A, 312B of the bottom wall 312 of the cassette 310 are placed opposite the openings 137A, 137B of the electronic card 135. The openings 312A of the bottom wall 312 of the cassette 310 are placed opposite the orifices 221 of the bottom wall 220 of the insertion well.

En position active, les volets 320A de l'élément de fermeture 320 sont interposés entre les orifices 312A de la cassette 310 et les orifices 221 du fond 220 du puits d'insertion de l'enjoliveur 200 pour interdire l'accès aux bornes de connexion électrique de phase et de neutre de la prise de courant.In the active position, the flaps 320A of the closing element 320 are interposed between the orifices 312A of the cassette 310 and the orifices 221 of the bottom 220 of the insert well of the trim 200 to prevent access to the connection terminals electrical phase and neutral of the socket.

Lorsqu'une fiche électrique est insérée dans le puits d'insertion de l'enjoliveur 200 de la prise de courant 10, les broches de cette fiche appuient sur les surfaces inclinées des volets 320A et provoquent le pivotement de l'élément de fermeture 320 pour s'enfoncer au travers des ouvertures 312A à l'intérieur du socle 100 afin d'accéder aux bornes de connexion électrique de phase et de neutre de la prise de courant.When an electrical plug is inserted into the insert well of the trim 200 of the socket 10, the pins of this plug press on the inclined surfaces of the flaps 320A and cause the closure member 320 to pivot to insert through the openings 312A inside the base 100 in order to access the phase and neutral electrical connection terminals of the socket.

Lorsque la fiche électrique est retirée du puits d'insertion de la prise de courant, les volets 320A de l'élément de fermeture 320 sont ramenés en position active par l'intermédiaire d'un ressort de compression 330 monté entre un ergot (non représenté) prévu sur un côté de l'élément de fermeture 320 et une paroi d'un logement 316 de la cassette 310. Enfin, il est prévu à l'intérieur de la cassette 310 une cloison qui limite le débattement en rotation de l'élément de fermeture 320.When the electrical plug is withdrawn from the socket insertion well, the flaps 320A of the closure element 320 are returned to the active position by means of a compression spring 330 mounted between a lug (not shown ) provided on one side of the closure element 320 and a wall of a housing 316 of the cassette 310. Finally, there is provided inside the cassette 310 a partition which limits the rotational movement of the element lock 320.

La prise de courant 10 représentée sur les figures 1 à 5 est une prise de courant connectée au standard Schuko®.The socket 10 shown on the figures 1 to 5 is a socket outlet connected to the Schuko® standard.

Selon le standard Schuko®, la mise à la terre est réalisée par l'intermédiaire d'une lyre conductrice 240. La lyre conductrice 240 comprend une languette de jonction 241 s'étendant entre deux branches 242 symétriques. Chacune des branches 242 forme un angle inférieur à 90 degrés par rapport à la languette de jonction 241. La lyre conductrice 240 est classiquement formée dans un matériau métallique, généralement un matériau métallique déformable (par exemple sous l'action d'une fiche électrique).According to the Schuko® standard, the earthing is carried out by means of a conducting lyre 240. The conducting lyre 240 comprises a junction tab 241 extending between two symmetrical branches 242. Each of the branches 242 forms an angle of less than 90 degrees relative to the junction tab 241. The conductive lyre 240 is conventionally formed from a metallic material, generally a deformable metallic material (for example under the action of an electric plug). .

De manière classique, les branches 242 s'étendent dans le puits d'insertion de l'enjoliveur afin d'être accessibles à une fiche électrique insérée dans celui-ci. Comme le montrent les figures 3, 4 et 5, les branches 242 sont décollées de la paroi latérale 210 du puits d'insertion de l'enjoliveur 200. Ainsi, lorsqu'une fiche électrique est insérée dans le puits d'insertion de l'enjoliveur 200, celle-ci déforme les branches 242 de la lyre conductrice 240 en prenant appui sur les branches 242 afin d'établir un contact électrique avec les contacts de terre de la fiche électrique.Conventionally, the branches 242 extend into the insert well of the cover so as to be accessible to an electrical plug inserted therein. As the figures 3, 4 and 5 , the branches 242 are detached from the side wall 210 of the insert hole of the cover 200. Thus, when an electrical plug is inserted into the insert well of the trim 200, the latter deforms the branches 242 of the conductive lyre 240 by resting on the branches 242 in order to establish electrical contact with the earth contacts of the electrical plug.

De manière avantageuse ici, la languette de jonction 241 de la lyre conductrice 240 est logée dans le puits d'insertion de l'enjoliveur 200. Cette disposition permet alors de libérer de l'espace dans le socle 100 qui présente un volume interne limité dû à ses dimensions standardisées. Cela permet notamment l'implantation de la carte électronique 135 dans le socle 100 afin d'obtenir une prise de courant 10 connectée.Advantageously here, the junction tab 241 of the conductive lyre 240 is housed in the insertion well of the cover 200. This arrangement then makes it possible to free up space in the base 100 which has a limited internal volume due to to its standardized dimensions. This allows in particular the implantation of the electronic card 135 in the base 100 in order to obtain a connected socket 10.

Le puits d'insertion de l'enjoliveur 200 est agencé de manière à accueillir la lyre conductrice 240. La paroi latérale 210 et la paroi de fond 220 du puits d'insertion comportent un logement ouvert vers le centre du puits d'insertion et destiné à accueillir une partie de la lyre conductrice 240. Comme le montrent les figures 1, 3 et 4, le logement ouvert de la paroi latérale 210 est formé par deux renfoncements symétriques 245A. Chaque renfoncement 245A est destiné à accueillir une partie inférieure de chaque branche 242 de la lyre conductrice 240. Lorsqu'une fiche électrique est insérée dans le puits d'insertion, chaque branche 242 va se déformer élastiquement et se loger dans l'un des renfoncements 245A. Les renfoncements 245A permettent donc d'assurer une bonne tenue mécanique de la lyre conductrice 240 dans le puits d'insertion lorsqu'une fiche électrique y est insérée.The insert well of the cover 200 is arranged to receive the conductive lyre 240. The side wall 210 and the bottom wall 220 of the insertion well have a housing open towards the center of the insertion well and intended for to accommodate part of the conductive lyre 240. As shown in the figures 1 , 3 and 4 , the open housing of the side wall 210 is formed by two symmetrical recesses 245A. Each recess 245A is intended to accommodate a lower part of each branch 242 of the conductive lyre 240. When an electrical plug is inserted into the insertion well, each branch 242 will deform elastically and be housed in one of the recesses. 245A. The recesses 245A therefore make it possible to ensure good mechanical strength of the conductive lyre 240 in the insertion well when an electrical plug is inserted therein.

Dans la paroi de fond du puits d'insertion, le logement ouvert est formé par une fente traversante 245B (figure 2). Cette fente traversante 245B loge la languette de jonction 241 de la lyre conductrice 240. Comme cela est visible sur la figure 2, la forme de la fente traversante 245B concorde avec celle de la languette de jonction 241 de la lyre conductrice 240.In the bottom wall of the insertion well, the open housing is formed by a through slot 245B ( figure 2 ). This through slot 245B houses the junction tab 241 of the conductive lyre 240. As can be seen on the figure. figure 2 , the shape of the through slot 245B matches that of the junction tab 241 of the conductive lyre 240.

De manière avantageuse ici, comme la languette de jonction 241 de la lyre conductrice 240 est disposée au niveau de la paroi de fond 220 du puits d'insertion, il est prévu une entretoise conductrice 140 raccordée à la borne de connexion de terre 141 afin d'effectuer une connexion électrique entre la lyre conductrice 240 et la borne de connexion de terre 141. En pratique, l'entretoise conductrice 140 est sertie à la borne de connexion de terre 141 de manière à la relier électriquement à la borne de connexion de terre 141.Advantageously here, as the junction tab 241 of the conductive lyre 240 is disposed at the level of the bottom wall 220 of the insertion well, there is provided a conductive spacer 140 connected to the earth connection terminal 141 in order to '' make an electrical connection between the conductive lyre 240 and the earth connection terminal 141. In practice, the conductive spacer 140 is crimped to the earth connection terminal 141 so as to connect it electrically to the earth connection terminal 141.

Afin d'établir un contact électrique entre la borne de connexion de terre 141 logée dans le socle 100 et la lyre conductrice 240 logée entièrement dans le puits d'insertion de l'enjoliveur 200 (la languette de jonction de cette lyre conductrice étant finalement logée dans l'épaisseur du fond du puits d'insertion), l'entretoise conductrice 140 traverse ladite ouverture circulaire 137B de la carte électronique 135 et la cassette 310 du dispositif de sécurité 300 de manière à émerger au niveau ou juste au-dessus de la paroi de fond 220 du puits d'insertion. Par l'expression « juste au-dessus », on entend que l'extrémité libre de l'entretoise conductrice 140 dépasse de la paroi de fond 220 de quelques millimètres.In order to establish an electrical contact between the earth connection terminal 141 housed in the base 100 and the conductive lyre 240 housed entirely in the insertion well of the trim 200 (the junction tab of this conductive lyre being finally housed in the thickness of the bottom of the insertion well), the conductive spacer 140 passes through said circular opening 137B of the electronic card 135 and the cassette 310 of the safety device 300 so as to emerge at the level or just above the bottom wall 220 of the insertion well. By the expression “just above” is meant that the free end of the conductive spacer 140 protrudes from the bottom wall 220 by a few millimeters.

En pratique, la borne de connexion de terre 141, munie de l'entretoise conductrice 140, est introduite par l'arrière de la carte électronique 135. Comme le montrent les figures 1 et 2, l'entretoise conductrice 140 est en forme de tronçon cylindrique. Elle traverse alors l'ouverture circulaire 137B de la carte électronique 135 et l'ouverture 312B correspondante de la cassette 310 du dispositif de sécurité 300 pour émerger dans la fente traversante 245B de la paroi de fond 220 du puits d'insertion de l'enjoliveur 200.In practice, the earth connection terminal 141, provided with the conductive spacer 140, is introduced from the rear of the electronic card 135. As shown in the figures. figures 1 and 2 , the conductive spacer 140 is in the form of a cylindrical section. It then passes through the circular opening 137B of the electronic card 135 and the corresponding opening 312B of the cassette 310 of the safety device 300 to emerge into the through slot 245B of the bottom wall 220 of the insert well of the trim. 200.

Comme le montrent les figures 1 à 3, la languette de jonction 241 comprend un orifice 241A, la languette de jonction 241 étant plus large au niveau de cet orifice 241A que sur le reste de sa longueur. Cet orifice 241A est positionné au niveau de l'orifice de passage duquel émergerait la broche de terre d'une prise de courant au standard franco-belge.As the figures 1 to 3 , the junction tab 241 comprises an orifice 241A, the junction tab 241 being wider at this orifice 241A than over the remainder of its length. This orifice 241A is positioned at the level of the passage orifice from which the earth pin of a Franco-Belgian standard socket would emerge.

La section de cet orifice 241A est donc sensiblement égale à celle de l'orifice de passage de la broche de terre d'une prise franco-belge, par exemple de forme circulaire avec un diamètre compris entre 4,2 et 5,4 millimètres. Ici, le centre O3 de l'orifice 241A (figure 3) appartient à la droite passant par le centre O de la paroi de fond 220 du puits d'insertion et perpendiculaire à la droite passant par les centres O1, O2 des deux orifices 241. En particulier, la distance entre le centre O3 de l'orifice 241A et le centre O de la paroi de fond 220 du puits d'insertion est comprise entre 9,9 et 10,1 mm.The section of this orifice 241A is therefore substantially equal to that of the orifice for the passage of the earth pin of a Franco-Belgian plug, for example of circular shape with a diameter of between 4.2 and 5.4 millimeters. Here, the center O3 of port 241A ( figure 3 ) belongs to the line passing through the center O of the bottom wall 220 of the insertion well and perpendicular to the line passing through the centers O1, O2 of the two orifices 241. In particular, the distance between the center O3 of the port 241A and the center O of the bottom wall 220 of the insertion well is between 9.9 and 10.1 mm.

L'extrémité libre de l'entretoise conductrice 140 émerge donc dans la languette de jonction 241 au niveau de cet orifice 241A. La section de l'entretoise conductrice 140 présente donc une section sensiblement égale à celle d'une broche de terre d'une prise de courant au standard franco-belge, par exemple de forme circulaire avec un diamètre compris entre 4,2 et 5,4 millimètres.The free end of the conductive spacer 140 therefore emerges in the junction tab 241 at the level of this orifice 241A. The section of the conductive spacer 140 therefore has a section substantially equal to that of an earth pin of a socket outlet to the Franco-Belgian standard, for example circular in shape with a diameter between 4.2 and 5, 4 millimeters.

Comme le montrent les figures 3 et 5, l'entretoise conductrice 140 est sertie à la lyre conductrice 240. Ce sertissage est réalisé au niveau de l'orifice 241A de la languette de jonction 241. Le sertissage permet d'assurer un contact électrique entre la lyre conductrice 240 et la borne de connexion de terre 141 et d'assurer une tenue mécanique de la lyre conductrice 240 sur la paroi de fond 220 du puits d'insertion.As the figures 3 and 5 , the conductive spacer 140 is crimped to the conductive lyre 240. This crimping is carried out at the level of the orifice 241A of the junction tab 241. The crimping ensures electrical contact between the conductive lyre 240 and the terminal of earth connection 141 and ensure a mechanical strength of the conductive lyre 240 on the bottom wall 220 of the insertion well.

Comme précisé précédemment, la forme de la fente traversante 245B est complémentaire de la forme de la languette de jonction 241 de la lyre conductrice 240. En particulier, la fente traversante 245B est plus large au niveau de sa partie qui va accueillir la partie de la languette de jonction 241 au niveau de laquelle se trouve l'orifice 241A. Après sertissage de l'entretoise conductrice sur la languette de jonction 241, la fente traversante 245B est donc fermée par la lyre conductrice 240 (figure 3).As specified previously, the shape of the through slot 245B is complementary to the shape of the junction tab 241 of the conductive lyre 240. In particular, the through slot 245B is wider at its part which will receive the part of the junction tab 241 at which the orifice 241A is located. After crimping the conductive spacer on the junction tab 241, the through slot 245B is therefore closed by the conductive lyre 240 ( figure 3 ).

Comme le montre plus particulièrement la figure 4, un moyen de retenue 250 est disposé sur la paroi de fond 220 du puits d'insertion lorsque la lyre conductrice 240 est introduite dans la fente traversante 245B afin de renforcer la tenue mécanique de la lyre conductrice 240 sur la paroi de fond 220 du puits d'insertion. Le moyen de retenue 250 présente deux ouvertures en regard des orifices 221 de la paroi de fond 220 du puits d'insertion (par lesquelles la fiche électrique va être introduite).As shown more particularly by figure 4 , a retaining means 250 is disposed on the bottom wall 220 of the insertion well when the conductive lyre 240 is introduced into the through slot 245B in order to reinforce the mechanical strength of the conductive lyre 240 on the bottom wall 220 of the well insertion. The retaining means 250 has two openings facing the orifices 221 of the bottom wall 220 of the insertion well (through which the electrical plug will be inserted).

Ce moyen de retenue 250 permet notamment de maintenir la lyre conductrice 240 dans la paroi de fond 220 du puits d'insertion lors de l'insertion et de la désinsertion d'une fiche électrique dans la prise de courant 10.This retaining means 250 makes it possible in particular to maintain the conductive lyre 240 in the bottom wall 220 of the insertion well during the insertion and the uninsertion of an electrical plug in the socket 10.

Ici, le moyen de retenue 250 est un élément plat autocollant, en particulier une vignette autocollante collée sur la paroi de fond 220 du puits d'insertion de manière à la recouvrir pratiquement totalement en recouvrant par là même une partie de la lyre conductrice 240.Here, the retaining means 250 is a flat self-adhesive element, in particular a self-adhesive sticker stuck on the bottom wall 220 of the insertion well so as to cover it almost completely, thereby covering part of the conductive lyre 240.

On notera que de façon avantageuse dans la prise de courant 10 conforme à l'invention au standard Schuko®, la carte électronique est une carte usuelle du marché, généralement utilisée dans une prise de courant connectée au standard franco-belge, et, ici, l'ouverture circulaire 137B de cette carte électronique, qui est disposée à un endroit excentré par rapport au centre de la carte et qui est généralement utilisée pour le passage de la broche de terre d'une prise de courant au standard franco-belge, sert au passage de l'entretoise conductrice 140 qui établit la connexion électrique entre la borne de connexion de terre 141 et la lyre de raccordement à la terre 240 placée, en dehors du volume intérieur du boîtier ou enveloppe 110, au niveau du fond du puits d'insertion de l'enjoliveur 200.It will be noted that advantageously in the socket 10 according to the invention with the Schuko® standard, the electronic card is a standard card on the market, generally used in a socket connected to the Franco-Belgian standard, and, here, the circular opening 137B of this electronic card, which is placed at a location eccentric with respect to the center of the card and which is generally used for the passage of the earth pin of a socket with the Franco-Belgian standard, serves the passage of the conductive spacer 140 which establishes the electrical connection between the earth connection terminal 141 and the earth connection bracket 240 placed, outside the internal volume of the housing or envelope 110, at the level of the bottom of the well d inserting the hub cap 200.

La présente invention n'est pas limitée aux modes de réalisation décrits et représentés sur les différentes figures, mais l'homme du métier saura y apporter toute variante conforme à son esprit.The present invention is not limited to the embodiments described and shown in the various figures, but those skilled in the art will know how to make any variant in accordance with their spirit.
