Description

DOMAINE TECHNIQUE AUQUEL SE RAPPORTE L'INVENTIONTECHNICAL FIELD TO WHICH THE INVENTION REFERS

La présente invention concerne de manière générale les appareillages électriques qui comprennent un quelconque mécanisme d'appareillage, tel que par exemple un mécanisme d'interrupteur ou de prise de courant, dans une boîte à encastrer dans une paroi quelconque ou dans un boîtier à rapporter en saillie d'une telle paroi.The present invention generally relates to electrical apparatus which comprises any apparatus mechanism, such as for example a switch or socket mechanism, in a box for mounting in any wall or in a housing to be reported in projecting from such a wall.

Elle concerne en particulier un appareillage électrique comprenant un entraîneur monté à pivotement dans un socle pour ouvrir et fermer des contacts électriques contenus dans ledit socle, et des moyens d'éclairage adaptés à l'éclairage d'une zone de façade dudit appareillage.It relates in particular to electrical equipment comprising a driver pivotally mounted in a base for opening and closing electrical contacts contained in said base, and lighting means adapted to illuminate a facade area of said apparatus.

L'invention trouve une application particulièrement avantageuse dans la réalisation d'un interrupteur électrique à fonction lumineuse, visible dans la pénombre.The invention finds a particularly advantageous application in the production of an electric switch with a light function, visible in dim light.

ARRIERE-PLAN TECHNOLOGIQUEBACKGROUND

On connaît déjà, notamment du document GB 2 083 708 , des appareillages électriques du type précité qui intègrent une fonction lumineuse pour être repérés dans une pièce sombre et/ou indiquer à l'usager leur état de fonctionnement (ouvert ou fermé).We already know, especially the document GB 2,083,708 , electrical equipment of the aforementioned type which incorporates a light function to be located in a dark room and / or indicate to the user their operating status (open or closed).

Dans les appareillages électriques déjà connus, les moyens d'éclairage comprennent une source lumineuse (une diode ou une ampoule à filaments) disposée à l'intérieur du boîtier d'appareillage. Cette source lumineuse, raccordée électriquement aux bornes de connexion du mécanisme d'appareillage, émet un faisceau lumineux en direction de la touche de commande accessible à l'usager pour éclairer directement ou indirectement une fenêtre pratiquée dans la façade de ladite touche et former un trait ou un point lumineux sur celle-ci.In electrical equipment already known, the lighting means comprise a light source (a diode or a filament bulb) disposed inside the gearbox. This light source, electrically connected to the connection terminals of the fitting mechanism, emits a light beam in the direction of the control button accessible to the user to illuminate directly or indirectly a window made in the facade of said key and form a line or a bright spot on it.

Dans l'appareillage électrique selon le document GB 2 083 708 , la source lumineuse est déportée latéralement par rapport à la fenêtre de la touche de commande à éclairer. Les moyens d'éclairage comprennent alors un guide optique embarqué dans ladite touche de commande qui récupère la lumière émise par la source lumineuse et la guide vers la fenêtre à éclairer.In the electrical equipment according to the document GB 2,083,708 , the light source is offset laterally relative to the window of the control key to be illuminated. The lighting means then comprise an optical guide embedded in said control key which retrieves the light emitted by the light source and the guide to the window to be illuminated.

Par ailleurs, le document US 4 710 858 décrit un appareil électrique comprenant une touche de commande basculante transparente illuminée classiquement par l'arrière au moyen d'une source lumineuse, cette touche de commande comportant un cadre opaque pour éviter les fuites de lumière entre ladite touche et le bord de l'ouverture de montage de la touche. II est également prévu selon ce document un agencement de moyens de basculement de la touche, de guide de lumière et de mousse opaque pour que la lumière émise par la source soit guidée jusqu'à la face arrière de la touche en évitant tout fuite latérale de lumière lors du basculement de ladite touche.In addition, the document US 4,710,858 discloses an electrical apparatus comprising a transparent tilt control key conventionally illuminated from the rear by means of a light source, this control key having an opaque frame to prevent light leakage between said key and the edge of the opening of mounting the key. It is also provided according to this document an arrangement of tilting means of the key, light guide and opaque foam so that the light emitted by the source is guided to the rear face of the key avoiding any lateral leak of light when tilting said key.

Le document DE 20 2004 003 530 U1 décrit un appareil électrique qui comprend deux touches basculantes. Chaque touche basculante est associée à une source lumineuse qui éclaire un guide de lumière, solidaire de la touche, comportant, d'une part, une partie d'extrémité débouchant au centre de la touche de façon à former une zone centrale lumineuse sur la façade de ladite touche, et, d'autre part, une nez situé à l'arrière de la touche destiné à actionner un interrupteur de commande de la source lumineuse.The document DE 20 2004 003 530 U1 describes an electrical apparatus that includes two rocker keys. Each tilting key is associated with a light source which illuminates a light guide, integral with the key, comprising, on the one hand, an end portion opening at the center of the key so as to form a central light zone on the facade of said key, and, secondly, a nose located at the rear of the key for actuating a control switch of the light source.

Enfin les documents GB 2 083 708 et FR 2 045 846 décrivent des interrupteurs à bascule du même type dans lesquels il est prévu une source de lumière déportée par rapport à l'axe de pivotement de la touche basculante et un guide de lumière adapté à ramener la lumière émise par la source en façade (voir GB 2 083 708 ) ou sur un côté ( FR 2 045 846 ) de ladite touche.Finally documents GB 2,083,708 and FR 2,045,846 describe rocker switches of the same type in which there is provided a light source offset from the axis of pivoting of the rocking key and a light guide adapted to reduce the light emitted by the source in front (see GB 2,083,708 ) or on one side ( FR 2,045,846 ) of said key.

En préliminaire, on notera que, d'une figure à l'autre, les éléments identiques ou similaires des différents modes de réalisation représentés, seront dans la mesure du possible référencés par les mêmes signes de référence et ne seront pas décrits à chaque fois.As a preliminary, it will be noted that, from one figure to another, the identical or similar elements of the various embodiments represented will be as far as possible referenced by the same reference signs and will not be described each time.

Sur les figures 1 à 9 on a représenté un appareillage électrique comprenant un socle 100 un module destiné à être monté dans un support d'appareillage non représenté.On the Figures 1 to 9 there is shown an electrical apparatus comprising a base 100 a module to be mounted in a device support not shown.

Ce socle 100, réalisé d'une seule pièce en matière plastique moulée, contient le mécanisme électrique (non visible sur les figures) de l'appareillage électrique.This base 100, made in one piece of molded plastic material, contains the electrical mechanism (not visible in the figures) of the electrical equipment.

Il peut s'agir d'un mécanisme d'interrupteur ou de va-et-vient.It can be a switch mechanism or back-and-forth.

Le socle 100 porte sur sa face arrière (voir figure 9) des ouvertures 120 d'accès aux bornes de connexion électrique du mécanisme d'appareillage contenu dans ledit socle. Il comporte par ailleurs sur deux faces latérales opposées des pattes 110 munies d'une dent d'encliquetage 111 pour le montage par encliquetage du socle 100 sur le support d'appareillage correspondant. Sur sa face avant, il est bordé d'un rebord 101,112 qui prend appui sur le support d'appareillage correspondant.The base 100 bears on its rear face (see figure 9 ) 120 openings for access to the electrical connection terminals of the equipment mechanism contained in said base. It also has on two opposite side faces lugs 110 provided with a ratchet tooth 111 for snap-fitting of the base 100 on the corresponding equipment support. On its front face, it is bordered by a rim 101,112 which bears on the corresponding equipment support.

De manière connue en soi, l'appareillage électrique comprend un entraîneur 200 monté à pivotement autour d'un axe X dans le socle 100 pour ouvrir et fermer les contacts électriques du mécanisme d'appareillage contenu dans ledit socle 100.In a manner known per se, the electrical equipment comprises a driver 200 mounted to pivot about an axis X in the base 100 to open and close the electrical contacts of the equipment mechanism contained in said base 100.

L'appareillage électrique comprend également des moyens d'éclairage adaptés à l'éclairage d'une zone de façade dudit appareillage.The electrical equipment also comprises lighting means adapted to illuminate a façade area of said apparatus.

Selon l'exemple de réalisation représenté sur les figures 1 à 9 lesdits moyens d'éclairage sont agencés de manière à former un trait lumineux sur la façade 300A d'une touche de commande 300 de l'appareillage électrique (voir figure 6).According to the exemplary embodiment shown on Figures 1 to 9 said lighting means are arranged so as to form a light line on the facade 300A of a control key 300 of the electrical equipment (see figure 6 ).

La touche de commande 300 accessible à l'usager est encliquetée sur l'entraîneur 200 pour le faire pivoter autour de l'axe X de pivotement.The control key 300 accessible to the user is snapped onto the driver 200 to rotate about the pivot axis X.

De façon particulièrement avantageuse, ces moyens d'éclairement comprennent une source lumineuse 403 qui émet un flux lumineux en direction d'un guide optique 202A,204 adapté à guider ce flux lumineux selon l'axe X de pivotement dudit entraîneur 200.In a particularly advantageous manner, these illumination means comprise a light source 403 which emits a luminous flux towards an optical guide 202A, 204 adapted to guide this luminous flux along the axis X of pivoting of said driver 200.

Comme le montre plus particulièrement la figure 2, la source lumineuse comprend ici quatre diodes électroluminescentes 403 positionnées côte à côte aux quatre coins d'un rectangle, connectées à un circuit imprimé supporté sur la face arrière d'une carte de circuit imprimé 404 enveloppée d'une enveloppe isolante 401 pour former une cassette 400. Bien entendu l'enveloppe isolante 401 de la cassette 400 ne recouvre pas lesdites diodes électroluminescentes 403 qui apparaissent sur la face arrière de la cassette 400 dans une fenêtre 402 de ladite enveloppe. Le circuit imprimé est alimenté électriquement par l'intermédiaire de broches de contact 405 qui émergent de l'enveloppe isolante 401 pour être connectées aux bornes de connexion du mécanisme d'appareillage contenu dans le socle 100.As shown more particularly in figure 2 , the light source here comprises four light-emitting diodes 403 positioned side by side adjacent to the four corners of a rectangle, connected to a printed circuit supported on the rear face of a printed circuit board 404 wrapped with an insulating envelope 401 to form a cassette 400. Of course the insulating envelope 401 of the cassette 400 does not cover said light-emitting diodes 403 which appear on the rear face of the cassette 400 in a window 402 of said envelope. The printed circuit is electrically powered via contact pins 405 which emerge from the insulating jacket 401 to be connected to the connection terminals of the equipment mechanism contained in the base 100.

Comme le montrent plus particulièrement les figures 3 et 4, selon l'exemple représenté, l'entraîneur 200 se présente sous la forme générale d'un berceau globalement rectangulaire, avec un fond 202 bordé par une paroi latérale périphérique 201 qui définit un logement 200A ouvert vers la façade de l'appareillage électrique.As shown more particularly by Figures 3 and 4 , according to the example shown, the driver 200 is in the general form of a generally rectangular cradle, with a bottom 202 bordered by a peripheral side wall 201 which defines a housing 200A open towards the front of the electrical equipment.

Il est monté à pivotement dans des chapes 130 du socle 100 au moyen de deux tourillons 204 positionnés de part et d'autre de la paroi latérale périphérique 201 selon l'axe X de pivotement.It is pivotally mounted in yokes 130 of the base 100 by means of two journals 204 positioned on either side of the peripheral side wall 201 along the axis X of pivoting.

La paroi latérale périphérique 201 de l'entraîneur 200 porte sur sa face externe des dents 201A permettant de rapporter par encliquetage la touche de commande 300.The peripheral side wall 201 of the driver 200 carries on its outer surface teeth 201A for the snap-on report of the control key 300.

L'entraîneur 200 comporte le long de deux côtés latéraux parallèles de la paroi latérale périphérique 201 des ailes 203 dont sont solidaires les tourillons 204 de pivotement de l'entraîneur 200. Ces ailes 203 comportent au niveau des tourillons 204 des encoches de sorte que l'entraîneur 200 présente deux espaces vides 205 entre la paroi latérale périphérique 201 et les deux tourillons 204.The driver 200 comprises along two parallel lateral sides of the peripheral lateral wall 201 of the wings 203 which are integral with the pivots 204 pivoting the driver 200. These wings 203 have at the trunnions 204 notches so that the The driver 200 has two voids 205 between the peripheral side wall 201 and the two journals 204.

Ce berceau accueille la cassette 400 de sorte que sa face arrière de faisant apparaître lesdites diodes électroluminescentes 403 est tournée vers le fond 202 du berceau et que sa face avant recouverte de l'enveloppe isolante 401 est tournée vers la face avant de l'appareillage c'est-à-dire vers la touche de commande 300 de celui-ci.This cradle accommodates the cassette 400 so that its rear face causing said light-emitting diodes 403 to face the bottom 202 of the cradle and that its front face covered with the insulating envelope 401 is turned towards the front face of the apparatus c that is, to the control key 300 thereof.

Le fond 202 du berceau que forme l'entraîneur 200 comporte des ouvertures qui laissent passer les broches de contact 405 de la cassette 400 placée dans ledit berceau pour que lesdites broches puissent se connecter aux bornes de connexion du mécanisme d'appareillage prévues au fond du socle 100.The bottom 202 of the cradle formed by the driver 200 has openings which pass the contact pins 405 of the cassette 400 placed in said cradle so that said pins can connect to the connection terminals of the equipment mechanism provided at the bottom of the cradle. base 100.

Ici, le guide optique adapté à guider le flux lumineux émis par la source lumineuse des moyens d'éclairage selon l'axe X de pivotement de l'entraîneur appartient à l'entraîneur 200.Here, the optical guide adapted to guide the luminous flux emitted by the light source of the illumination means along the pivoting axis X of the trainer belongs to the trainer 200.

En particulier, ce guide optique comprend au moins une partie 202A du fond 202 de l'entraîneur 200.In particular, this optical guide comprises at least a portion 202A of the bottom 202 of the trainer 200.

Pour cela l'entraîneur 200 est réalisé en une matière plastique transparente comme du polycarbonate transparent ou du polymétacrylate de méthyle acrylonitrile transparent. Il est réalisé avantageusement d'une seule pièce en matière plastique transparente moulée.For this, the driver 200 is made of a transparent plastic material such as transparent polycarbonate or transparent methyl-acrylonitrile polymethacrylate. It is advantageously made of a single piece of molded transparent plastic material.

Lorsque la cassette 400 est positionnée dans l'entraîneur 200, les diodes électroluminescentes 403 sont disposées en vis-à-vis de la partie 202A du fond 202 du berceau formant le guide optique. Le flux lumineux émis par les diodes électroluminescentes 403 est guidé par le fond 202A du berceau selon les flèches F (voir figures 4 et 6) en direction des tourillons 204 de pivotement de l'entraîneur 200.When the cassette 400 is positioned in the driver 200, the light-emitting diodes 403 are disposed opposite the portion 202A of the bottom 202 of the cradle forming the optical guide. The luminous flux emitted by the light-emitting diodes 403 is guided by the bottom 202A of the cradle according to the arrows F (see FIG. figures 4 and 6 ) in the direction of pivot pins 204 of the driver 200.

En outre, comme le montrent plus particulièrement les figures 5 à 9, l'appareillage représenté comporte un conduit optique 500 apte à récupérer le flux lumineux guidé par le fond 202A de l'entraîneur 200 selon l'axe X de pivotement de celui-ci et à l'amener jusqu'à une fenêtre allongée 302 prévue dans la façade 300A de la touche de commande 300 de l'appareillage électrique.Moreover, as shown more particularly by Figures 5 to 9 , the apparatus shown comprises an optical conduit 500 adapted to recover the luminous flux guided by the bottom 202A of the driver 200 along the axis X of pivoting thereof and to bring it to an extended window 302 provided in the facade 300A of the control key 300 of the electrical equipment.

Ici comme le montre plus particulièrement les figures 5 et 6, le conduit optique 500, réalisé en matière plastique moulée transparente, présente une forme adaptée à une touche de commande 300 de forme carrée dite touche deux modules. Il suit le contour globalement d'un trapèze qui déborde du gabarit du socle 100. Il comporte deux extrémités 501A, 502A d'entrée du flux lumineux situées de part et d'autre de l'entraîneur 200 sur ledit axe X de pivotement. Chacune de ces extrémités 501A 502A est insérée dans un desdits espaces vides 205 situé entre ladite paroi latérale périphérique 201 du berceau et une extrémité intérieure d'un tourillon 204 de pivotement de ce dernier.Here, as shown more particularly by Figures 5 and 6 , the optical conduit 500, made of transparent molded plastic, has a shape adapted to a control key 300 of square shape so called two modules. It follows the overall contour of a trapezium which protrudes from the template of the base 100. It has two ends 501A, 502A input of the luminous flux located on either side of the driver 200 on said axis X pivoting. Each of these ends 501A 502A is inserted into one of said empty spaces 205 located between said peripheral side wall 201 of the cradle and an inner end of a pivot pivot pin 204 thereof.

À partir de ces extrémités 501A, 502A d'entrée, le conduit optique 500 comporte deux parties de guidage 501,502 du flux lumineux qui contournent (l'une par la gauche, l'autre par la droite) la paroi latérale périphérique 201 de l'entraîneur 200 et qui se raccordent à une partie de diffusion 503 qui s'étend dans ladite fenêtre allongée 302 à éclairer.From these input ends 501A, 502A, the optical conduit 500 has two guide portions 501, 502 of the luminous flux which bypass (one from the left, the other from the right) the peripheral lateral wall 201 of the 200 and which connect to a diffusion portion 503 which extends into said elongated window 302 to illuminate.

Le conduit optique 500 est un conduit plein réalisé d'une seule pièce par moulage d'une matière plastique transparente par exemple identique à celle qui constitue l'entraîneur 200.The optical conduit 500 is a solid conduit made in one piece by molding a transparent plastic material, for example identical to that which constitutes the driver 200.

Ainsi, comme le montre plus particulièrement la figure 6, la majeure partie du flux lumineux émis par les diodes électroluminescentes 403 en direction du fond du socle 100 est récupérée par la partie 202A du fond 202 de l'entraîneur 200 et est guidée selon les flèches F selon l'axe X de pivotement de l'entraîneur pour être récupérée par le conduit optique 500 et guidée jusqu'à la partie de diffusion 503 de ce dernier pour former un trait lumineux sur la façade 301 de la touche de commande 300 de l'appareillage électrique.Thus, as shown more particularly by figure 6 the majority of the luminous flux emitted by the light-emitting diodes 403 towards the bottom of the base 100 is recovered by the part 202A of the bottom 202 of the trainer 200 and is guided according to the arrows F along the pivot axis X of the trainer to be recovered by the optical conduit 500 and guided to the diffusion portion 503 of the latter to form a light line on the facade 301 of the control key 300 of the electrical equipment.

Avantageusement, comme le montre la figure 9, la touche de commande 300 comporte sur sa face arrière 300B des plots 301 de maintien du conduit optique 500 mis en place sur l'entraîneur 200 de l'appareillage.Advantageously, as shown in figure 9 , the control key 300 has on its rear face 300B studs 301 for maintaining the optical conduit 500 placed on the trainer 200 of the apparatus.

Sur la figure 10 on a représenté une variante de réalisation de l'appareillage de la figure 1 selon laquelle le conduit optique 500' présente une forme en U adaptée à celle d'une touche de commande 300' rectangulaire un module, dite touche piano.On the figure 10 there is shown an alternative embodiment of the apparatus of the figure 1 according to which the optical conduit 500 'has a U-shape adapted to that of a rectangular control key 300' a module, called a piano key.

Il est resserré autour de l'entraîneur 200 de sorte qu'il est logé dans le gabarit du socle 100. Les extrémités 501'A et 502'A des parties de guidage 501' et 502' de celui-ci sont situées sur l'axe X de pivotement de part et d'autre de l'entraîneur 200 à l'extérieur des tourillons de pivotement de ce dernier. La partie de diffusion 503' du conduit optique 500' est plus courte puisqu'elle s'étend seulement sur la largeur du socle 100.It is tightened around the driver 200 so that it is housed in the template of the base 100. The ends 501'A and 502'A of the guide portions 501 'and 502' thereof are located on the X axis pivoting on either side of the driver 200 outside the pivot pins of the latter. The diffusion portion 503 'of the optical conduit 500' is shorter since it extends only over the width of the base 100.

Sur les figures 11 et 12, on a représenté une autre variante de réalisation de l'appareillage électrique représenté sur la figure 1 selon laquelle l'entraîneur 200' monté à pivotement sur le socle du mécanisme d'appareillage non représenté forme également un berceau ouvert vers le fond du socle, avec un fond 202' et une paroi latérale périphérique 201' qui définissent un logement accueillant une carte de circuit imprimé 404' qui porte un circuit imprimé sur sa face avant et sur sa face arrière.On the Figures 11 and 12 another alternative embodiment of the electrical apparatus shown in FIG. figure 1 according to which the driver 200 'pivotally mounted on the base of the apparatus mechanism not shown also forms a cradle open towards the base of the base, with a bottom 202' and a peripheral side wall 201 'which define a housing accommodating a card printed circuit board 404 'which carries a printed circuit on its front face and on its rear face.

II est prévu, d'une part, sur la face arrière de la carte 404', deux diodes électroluminescentes connectées audit circuit imprimé et placées en regard des tourillons de l'entraîneur 200' pour former un flux lumineux selon l'axe X de pivotement de l'entraîneur 200', et, d'autre part, sur la face avant de la carte 404' tournée vers la touche de commande 300, deux autres diodes électroluminescentes 403' tournées vers le fond 202' de l'entraîneur 200'.On the one hand, on the rear face of the card 404 ', there are two light-emitting diodes connected to said printed circuit and placed opposite the trunnions of the driver 200' to form a luminous flux along the pivoting axis X of the coach 200 ', and, secondly, on the front of the card 404' turned towards the control key 300, two other light-emitting diodes 403 'turned towards the bottom 202' of the driver 200 '.

Le fond 202' de l'entraîneur 200 forme un guide optique qui guide le flux lumineux émis par ces diodes électroluminescentes 403' jusqu'à un conduit optique 500" en forme de T comportant une partie de guidage 501" qui s'étend en regard de l'entraîneur 200' pour récupérer le flux lumineux guidé par lui et une tête 502" servant de partie de diffusion qui s'étend dans la fenêtre allongée 302 de la touche d'actionnement à éclairer.The bottom 202 'of the driver 200 forms an optical guide which guides the luminous flux emitted by these light-emitting diodes 403' to a T-shaped optical conduit 500 "having a guide portion 501" which extends opposite of the trainer 200 'to recover the light flow guided by him and a head 502 "serving as a diffusion part which extends in the elongated window 302 of the actuating key to be illuminated.

Sur les figures 13 à 17, on a représenté un autre variante de réalisation de l'appareillage électrique représenté sur la figure 1, dans lequel il est prévu de part et d'autre de l'entraîneur 200, face à ses tourillons 204 de pivotement, des conduits optiques 610,620 agencés de manière à éclairer des parties latérales 701,702 d'une plaque enjoliveur 700 rapportée autour de la touche de commande 300" encliquetée sur l'entraîneur 200 pour former un halot lumineux de part et d'autre de cette touche de commande.On the Figures 13 to 17 another alternative embodiment of the electrical apparatus shown in FIG. figure 1 , in which is provided on either side of the driver 200, facing its pivot pins 204, optical conduits 610, 620 arranged to illuminate lateral portions 701, 702 of a trim plate 700 attached around the button control 300 "snapped onto the trainer 200 to form a halot light on either side of this control key.

Comme le montrent plus particulièrement les figures 14 à 17, chaque conduit optique 610,620 est relativement plat.
