Description

DOMAINE TECHNIQUE DE L'INVENTIONTECHNICAL FIELD OF THE INVENTION

L'invention est relative à un boîtier électrique multiprise comprenant au moins deux orifices donnant accès respectivement à un conducteur plat destinés à être reliés à une ligne électrique. Au moins deux conducteurs plats comporte des moyens de connexion destinés à recevoir des fiches mâles d'une prise externe.The invention relates to a multi-socket electrical box comprising at least two orifices giving access respectively to a flat conductor intended to be connected to a power line. At least two flat conductors have connection means for receiving plugs of an external plug.

ETAT DE LA TECHNIQUE ANTERIEURESTATE OF THE PRIOR ART

L'utilisation de boîtier électrique multiprise est très répandue pour raccorder plusieurs dispositifs électriques au secteur via un cordon d'alimentation et une seule prise électrique. En effet, un seul boîtier électrique multiprise permet de raccorder plusieurs dispositifs électriques au secteur.The use of multi-socket electrical boxes is widely used to connect several electrical devices to the mains via a power cord and a single electrical outlet. Indeed, a single power strip socket allows to connect several electrical devices to the sector.

Les boîtiers électriques multiprise comprennent des prises internes de courant. Lesdites prises internes comportent en général au moins deux trous permettant d'accueillir chacun une broche d'une prise externe s'insérant dans le socle de prise de courant. Les prises internes de courant peuvent aussi contenir des moyens de connexion à la terre. Ces moyens de connexion peuvent comporter une broche ou des pattes de connexion ayant notamment la forme d'une lyre.Multi-socket electrical boxes include internal power outlets. Said internal sockets generally comprise at least two holes for each to accommodate a pin of an external plug inserted into the socket outlet. The internal power outlets may also contain means of connection to the ground. These connection means may comprise a pin or connection lugs having in particular the shape of a lyre.

Les dispositifs électriques peuvent comporter une prise externe d'alimentation généralement destiné à être directement connectés au boîtier multiprise d'alimentation.The electrical devices may include an external power supply generally intended to be directly connected to the multi-outlet power supply unit.

La distribution phase, neutre est généralement réalisée de manières différentes par des conducteurs plats. Le conducteur peut être notamment réalisé à partir d'un profilé métallique plié en deux selon un axe de symétrie. Cette solution à faible cout de production a le défaut d'assurer une liaison électrique moyenne et de créer des échauffements au niveau des points de liaison.The phase neutral distribution is generally performed in different ways by flat conductors. The conductor may in particular be made from a metal section folded in two along an axis of symmetry. This low cost of production solution has the failure to provide a medium electrical connection and to create overheating at the points of connection.

Le conducteur plat peut aussi être réalisé en assemblant deux bandes conductrices face contre face. Les bandes sont par exemple assemblées par une opération de clinchage. En effet, les deux bandes métalliques sont fixées l'une à l'autre par emboutissage entre un poinçon et une matrice.The flat conductor can also be made by assembling two conductive strips face to face. The strips are for example assembled by a clinching operation. Indeed, the two metal strips are fixed to one another by stamping between a punch and a die.

Ces deux techniques de réalisation nécessitent des outillages spécifiques pour assurer l'opération de pliage ou de clinchage.These two production techniques require specific tools to ensure the folding or clinching operation.

La distribution de terre est souvent réalisée par un conducteur spécifique adaptée aux différents formats de raccordement de la fiche de terre. Exemple : par pincement en Allemagne, par une fiche en France. Par conséquence la distribution de la phase, neutre et terre n'est pas réalisé par des conducteurs identiques avec l'impact industriel de devoir approvisionner, gérer et stocker plusieurs références.The earth distribution is often carried out by a specific driver adapted to the different connection formats of the grounding plug. Example: by pinching in Germany, by a card in France. Consequently the distribution of the neutral and earth phase is not realized by identical conductors with the industrial impact of having to supply, manage and store several references.

On connaît les documents US 2007/184703 , EP0809333 et DE29920706 décrivant des boîtiers électriques multiprise comportant les caractéristiques du préambule de la revendication 1.We know the documents US 2007/184703 , EP0809333 and DE29920706 describing multi-socket electrical boxes having the features of the preamble of claim 1.

EXPOSE DE L'INVENTIONSUMMARY OF THE INVENTION

L'invention vise donc à remédier aux inconvénients de l'état de la technique, de manière à proposer un boîtier électrique multiprise dont la réalisation est optimisée.The invention therefore aims to overcome the drawbacks of the state of the art, so as to provide a multi-socket electrical box whose implementation is optimized.

A cet effet, la présente invention a pour objet un boîtier électrique multiprise selon la revendication 1. Dans un boîtier électrique multiprise selon l'invention, la configuration des zones de connexion d'une ondulation comportant deux bords espacés l'un de l'autre peut permette de prévoir un positionnement serré d'une fiche mâle d'une prise externe en sélectionnant une distance entre les deux bords parallèles sensiblement inférieure au diamètre de la fiche mâle prévue pour être insérée. De préférence, les deux bords de la zone de connexion d'une ondulation sont sensiblement perpendiculaires à un axe longitudinal dudit conducteur.To this end, the subject of the present invention is a multi-tap electrical box according to claim 1. In a multi-socket electric box according to the invention, the configuration of the connection zones of a corrugation having two edges spaced apart from one another may allow to provide a tight positioning of a plug of an external plug by selecting a distance between the two parallel edges substantially less than the diameter of the plug provided to be inserted. Preferably, the two edges of the connection zone of a corrugation are substantially perpendicular to a longitudinal axis of said conductor.

Avantageusement, les ondulations délimitant des zones de connexion comportent un axe de symétrie sensiblement perpendiculaire à l'axe longitudinal du conducteur.Advantageously, the corrugations delimiting connecting zones comprise an axis of symmetry substantially perpendicular to the longitudinal axis of the conductor.

Avantageusement, le conducteur comporte plusieurs ondulations réparties de manière périodique selon l'axe longitudinal dudit conducteur.Advantageously, the conductor comprises a plurality of corrugations distributed periodically along the longitudinal axis of said conductor.

Selon un mode particulier de réalisation, le boîtier électrique multiprise comporte un troisième conducteur identique destiné à être relié à la terre.According to a particular embodiment, the multi-socket electrical box comprises a third identical conductor intended to be connected to the ground.

Avantageusement, le boîtier électrique multiprise comporte des moyens de positionnement des conducteurs de manière à ce que les zones de connexion desdits conducteurs soient alignées avec les orifices.Advantageously, the multi-tap electrical box comprises means for positioning the conductors so that the connection areas of said conductors are aligned with the orifices.

Avantageusement, les moyens de positionnement sont en matériau isolant.Advantageously, the positioning means are made of insulating material.

DESCRIPTION DETAILLEE D'UN MODE DE REALISATIONDETAILED DESCRIPTION OF AN EMBODIMENT

Le boîtier électrique multiprise (1) selon les différents modes de réalisation de l'invention comprend une boite définissant un volume interne dans lequel sont positionnés au moins deux conducteurs plats 10. Lesdits conducteurs plats sont destinés à être reliés à une ligne électrique P, N, notamment à la phase P et au neutre N.The multi-socket electrical box (1) according to the various embodiments of the invention comprises a box defining an internal volume in which at least two flat conductors 10 are positioned. Said flat conductors are intended to be connected to an electrical line P, N , especially at phase P and at neutral N.

La boite comporte au moins deux prises internes de courant ayant respectivement deux orifices 3A, 3B. Chaque orifice 3A, 3B donne respectivement accès à une zone de connexion 14A d'un conducteur plat 10 distinct. Lesdites zones de connexion 14A sont destinées à recevoir les fiches males d'une prise externe 100. Chaque conducteur plat 10 comporte deux faces principales parallèles s'étendant sur un axe longitudinal Y du conducteur plat, autrement dit sur toute la longueur dudit conducteur.The box comprises at least two internal current taps respectively having two orifices 3A, 3B. Each orifice 3A, 3B respectively gives access to a connection zone 14A of a separate flat conductor 10. Said connection areas 14A are intended to receive the mating plugs of an external plug 100. Each flat conductor 10 has two parallel main faces extending along a longitudinal axis Y of the flat conductor, ie over the entire length of said conductor.

Comme représenté sur la figure 1, chaque conducteur plat 10 comporte des ondulations 14 délimitant les zones de connexion 14A destinées à recevoir les fiches mâles 101. Chaque conducteur plat 10 comporte au moins un tronçon 12 comprenant une ondulation formant la zone de connexion 14. Les zones de connexion 14A ont des axes longitudinaux Y2 sensiblement parallèle entre eux. En outre, les zones de connexion 14A ont des axes longitudinaux Y2 sensiblement perpendiculaire à un axe longitudinal Y du conducteur plat 10. Chaque conducteur plat 10 comporte au moins deux tronçons 12 conducteurs ayant respectivement une zone de connexion 14A.As shown on the figure 1 each flat conductor 10 comprises undulations 14 delimiting the connection areas 14A intended to receive the male plugs 101. Each flat conductor 10 comprises at least one section 12 comprising a corrugation forming the connection zone 14. The connection zones 14A have longitudinal axes Y2 substantially parallel to each other. In addition, the connection areas 14A have longitudinal axes Y2 substantially perpendicular to a longitudinal axis Y of the flat conductor 10. Each flat conductor 10 comprises at least two 12-conductor sections respectively having a connection zone 14A.

Selon un mode de réalisation de l'invention représenté sur la figure 1, les tronçons 12 d'un conducteur 10 sont reliés les uns aux autre par deux bandes rectilignes 12A. Une première extrémité d'une bande rectiligne 12A d'un premier tronçon 12 est reliée à l'ondulation 14 dudit tronçon et la seconde extrémité est reliée à une extrémité d'une autre bande rectiligne 12A d'un second tronçon 12. De préférence, comme représenté sur la figure 1, les bandes rectilignes 12A adjacentes de deux tronçons 12 distincts sont liées l'une à l'autre en formant un angle d'ouverture α. Cette déformation locale du conducteur 10 associée à son positionnement dans le boitier permet d'augmenter à la fois sa rigidité et son élasticité.According to one embodiment of the invention shown in figure 1 , the sections 12 of a conductor 10 are connected to each other by two straight strips 12A. A first end of a straight strip 12A of a first section 12 is connected to the corrugation 14 of said section and the second end is connected to one end of another straight strip 12A of a second section 12. Preferably, as represented on the figure 1 the rectilinear strips 12A adjacent to two distinct sections 12 are connected to each other by forming an opening angle α. This local deformation of the conductor 10 associated with its positioning in the case increases both its rigidity and elasticity.

La zone de connexion 14A d'une ondulation comporte deux bords espacés l'un de l'autre de manière à autoriser le positionnement serré d'une fiche mâle d'une prise externe 100. Selon un mode de réalisation avantageux représenté sur la figure 2, les deux bords de la zone de connexion 14 sont sensiblement parallèles. La distance entre les deux bords parallèles est sensiblement inférieure au diamètre de la fiche mâle d'une prise externe 100.The connection zone 14A of a corrugation has two edges spaced apart from one another so as to allow the tight positioning of a plug of an external plug 100. According to an advantageous embodiment shown in FIG. figure 2 the two edges of the connection zone 14 are substantially parallel. The distance between the two parallel edges is substantially less than the diameter of the plug of an external plug 100.

Chaque ondulation 14 comporte une zone évasée 14B reliée à la zone de connexion 14A. Ladite zone évasée 14B comporte deux bords espacés l'un de l'autre de manière à autoriser le positionnement par emboitement d'une ondulation d'une autre bande conductrice. Plus précisément, la zone de connexion 14A d'un premier tronçon 12 d'un premier conducteur plat 10 peut être placée à l'intérieur d'une zone évasée 14B d'un tronçon 12 d'un second conducteur plat. Ce positionnement respecte les distances diélectriques entre le premier et second conducteur. Comme représenté sur la figure 2, cette disposition est utile lorsqu'un troisième conducteur 10 plat identique aux deux autres conducteurs plats est présent dans le boîtier.Each corrugation 14 comprises a flared zone 14B connected to the connection zone 14A. Said flared zone 14B has two edges spaced from each other so as to allow interlocking positioning of a corrugation of another conductive strip. More specifically, the connection zone 14A of a first section 12 of a first flat conductor 10 may be placed inside a flared zone 14B of a section 12 of a second flat conductor. This positioning respects the dielectric distances between the first and second conductors. As shown on the figure 2 this arrangement is useful when a third flat conductor 10 identical to the other two flat conductors is present in the housing.

A titre d'exemple, le troisième conducteur 10 plat est notamment destiné à être relié à la terre (T). Le boîtier électrique multiprise comporte alors des moyens de liaison électrique 17 autorisant la connexion entre ledit troisième conducteur 10 et la borne de terre d'une prise externe 100. Les standards de réalisation des prises de terre peuvent être différents en fonction des pays. A titre d'exemple de réalisation, comme cela est représenté sur la figure 3, les moyens de liaison électrique 17 comportent d'une part un premier ergot destiné à s'insérer et se connecter dans une zone de connexion 14A du troisième conducteur plat 10 et d'autre part un second ergot de forme cylindrique destiné à faire saillie à l'extérieur du boîtier électrique multiprise pour la connexion avec une prise externe 100. Ce type de réalisation représenté à la figure 3 est particulièrement destiné à un standard de réalisation Français. Le second ergot peut aussi avoir la forme d'une lyre afin d'être adapté par exemple à un standard de réalisation Allemand.For example, the third flat conductor 10 is particularly intended to be connected to the earth (T). The multi-socket electrical box then comprises electrical connection means 17 allowing the connection between said third conductor 10 and the earth terminal of an external plug 100. The standards for making the earth connections may be different depending on the country. As an exemplary embodiment, as shown on the figure 3 the electrical connection means 17 comprise on the one hand a first lug intended to be inserted and connected in a connection zone 14A of the third flat conductor 10 and, on the other hand, a second cylindrically-shaped lug intended to protrude from the outside of the power strip box for connection with an external plug 100. This type of embodiment shown in FIG. figure 3 is particularly intended for a French production standard. The second lug may also be in the form of a lyre so as to be adapted for example to a German production standard.

Selon un mode de développement de l'invention, l'ondulation 14 comporte un axe de symétrie X sensiblement perpendiculaire à l'axe longitudinal Y du conducteur 10. Ledit conducteur comporte plusieurs ondulations 14 réparties de manière périodique selon l'axe longitudinal Y dudit conducteur.According to one embodiment of the invention, the corrugation 14 comprises an axis of symmetry X substantially perpendicular to the longitudinal axis Y of the conductor 10. Said conductor comprises a plurality of corrugations 14 distributed periodically along the longitudinal axis Y of said conductor .

Le boitier 1 comporte des moyens de positionnement 16 des conducteurs plats 10 de manière à ce que les trous de connexion 14 desdits conducteurs soient alignés avec les orifices 3A, 3B du boîtier 1. Comme représenté sur la figure 4, Les moyens de positionnement 16 des conducteurs 10 peuvent prendre de préférence la forme d'ergots faisant saillie dans le fond du boîtier. Les conducteurs plats 10 viennent s'entrelacer de part et d'autre ces ergots et sont ainsi maintenus en position. De préférence, les moyens de positionnement 16 sont en matériau isolant et font partie intégrante du boîtier électrique. Le boîtier électrique est réalisé notamment par moulage. En outre, les moyens de positionnement 16 jouent un rôle de diélectrique entre les conducteurs 10 placés dans le boîtier 1.The housing 1 comprises positioning means 16 of the flat conductors 10 so that the connection holes 14 of said conductors are aligned with the openings 3A, 3B of the housing 1. As shown in FIG. figure 4 , The positioning means 16 of the conductors 10 may preferably take the form of lugs protruding into the bottom of the housing. The flat conductors 10 are intertwined on both sides these pins and are thus held in position. Preferably, the positioning means 16 are made of insulating material and form an integral part of the electrical box. The electrical box is made in particular by molding. In addition, the positioning means 16 play a role of dielectric between the conductors 10 placed in the housing 1.

Selon tous les modes préférentiels de réalisation tels que représentés sur la figure 4, le boîtier électrique multiprise comporte des moyens d'interconnexion électrique 18 autorisant la connexion des conducteurs plats 10 à un cordon d'alimentation 19. Le cordon d'alimentation 19 ayant au moins deux fils électriques est destiné à connecter le boîtier électrique multiprise au secteur. Les moyens d'interconnexion électrique 18 comportent des ergots destinés à s'insérer respectivement dans une zone de connexion 14A et se connecter respectivement ainsi à un conducteur plat 10. Les fils électriques du cordon d'alimentation 19 sont connectés aux moyens d'interconnexion électrique 18 par des moyens de vissage ou des soudures.According to all the preferred embodiments as represented on the figure 4 , the multi-tap electrical box comprises electrical interconnection means 18 allowing the connection of the flat conductors 10 to a power cord 19. The power cord 19 having at least two electrical wires is intended to connect the multi-tap electrical box to the mains . The electrical interconnection means 18 comprise lugs intended to fit respectively in a connection zone 14A and thus respectively connect to a flat conductor 10. The electrical wires of the power cord 19 are connected to the electrical interconnection means 18 by screwing means or welds.
