Description

DOMAINE TECHNIQUE DE L'INVENTIONTECHNICAL FIELD OF THE INVENTION

La présente invention concerne de manière générale le domaine des installations électriques. Elle vise en particulier une prise électrique comprenant au moins deux alvéoles de réception d'une broche de contact électrique, et un circuit imprimé relié électriquement aux alvéoles. La présente invention vise également un procédé d'assemblage d'une telle prise électrique.The present invention relates generally to the field of electrical installations. It relates in particular to an electrical outlet comprising at least two cells for receiving an electrical contact pin, and a printed circuit electrically connected to the cells. The present invention also relates to a method of assembling such an electrical outlet.

De telles prises électriques combinent les fonctionnalités d'une prise électrique « classique », typiquement une prise encastrée destinée à recevoir une fiche électrique, à des fonctionnalités complémentaires liées au circuit imprimé. Ces prises électriques trouvent par exemple leur application ou usage dans le domaine de l'Internet des objets, en tant que prises connectées via un réseau de communication de données de type Internet.Such electrical outlets combine the functionalities of a “conventional” electrical outlet, typically a recessed outlet intended to receive an electrical plug, with additional functionalities linked to the printed circuit. These electrical outlets find, for example, their application or use in the field of the Internet of Things, as outlets connected via an Internet-type data communication network.

ETAT DE LA TECHNIQUE ANTERIEURESTATE OF THE PRIOR ART

Il est connu des prises électriques comprenant au moins deux alvéoles de réception d'une broche de contact électrique, et un circuit imprimé relié électriquement aux alvéoles. Un exemple de prise électrique de ce genre est connu du document US 7 549 874 B2 . La prise électrique décrite dans ce document comprend un socle, un circuit imprimé, et plusieurs alvéoles de réception d'une broche de contact électrique. Le socle est muni d'un logement intérieur débouchant sur une ouverture centrale. Le circuit imprimé est agencé au sein du logement intérieur du socle. Chaque alvéole de réception est agencée au sein du logement intérieur du socle de sorte à être disposée en regard de l'ouverture centrale, et est fixée dans un compartiment dédié aménagé au sein du socle. Chaque alvéole est soudée à une de ses extrémités au circuit imprimé, et est propre à enserrer une broche de contact électrique d'une fiche électrique de sorte à maintenir un contact électrique entre la broche et l'alvéole.
Autre exemple de l'art antérieur, le document US2011104919 A1 divulgue une prise électrique conforme au préambule de la revendication 1.Electrical outlets are known comprising at least two cells for receiving an electrical contact pin, and a printed circuit electrically connected to the cells. An example of an electrical outlet of this kind is known from the document US 7,549,874 B2 . The electrical outlet described in this document comprises a base, a printed circuit, and several receptacles for receiving an electrical contact pin. The base has an interior housing opening out to a central opening. The printed circuit is arranged within the interior housing of the base. Each receiving cell is arranged within the interior housing of the base so as to be arranged facing the central opening, and is fixed in a dedicated compartment arranged within the basement. Each cell is welded at one of its ends to the printed circuit, and is suitable for gripping an electrical contact pin of an electrical plug so as to maintain electrical contact between the pin and the cell.
Another example of the prior art, the document US2011104919 A1 discloses an electrical outlet according to the preamble of claim 1.

Dans une prise classique, et a fortiori dans une telle prise électrique, il est toutefois essentiel que les alvéoles de réception soient positionnées et ajustées avec le minimum de jeu possible au sein des compartiments dédiés du socle. En effet, ceci permet de garantir un fonctionnement correct entre les alvéoles de la prise et les broches de la fiche, notamment en termes de pression exercée par les alvéoles sur les broches, de qualité du contact électrique établi et de limitation des échauffements.In a conventional socket, and a fortiori in such an electrical socket, it is however essential that the receiving cells are positioned and adjusted with the minimum possible play within the dedicated compartments of the base. In fact, this makes it possible to guarantee correct operation between the sockets of the socket and the pins of the plug, in particular in terms of the pressure exerted by the sockets on the pins, of the quality of the electrical contact established and of limiting overheating.

Toutefois, l'un des problèmes liés à la prise électrique telle que décrite dans le document US 7 549 874 B2 est que, pour réussir l'assemblage de la prise, il est nécessaire de laisser suffisamment de jeu entre les alvéoles de réception et leurs compartiments respectifs afin d'autoriser toutes les dispersions de positionnement consécutives au soudage préalable des alvéoles sur le circuit imprimé. Par conséquent, du fait de ce jeu excessif entre les alvéoles et leurs compartiments respectifs dans le socle, les alvéoles ne peuvent pas être ajustées précisément dans leurs compartiments et les performances des premières s'en trouvent dégradées, notamment du point de vue de la qualité des contacts entre fiches et prises. En outre, la fixation des alvéoles dans les compartiments du socle est rendue difficile du fait du soudage préalable des alvéoles sur le circuit imprimé, et de l'encombrement de l'ensemble en résultant, ainsi que de la sollicitation des soudures des alvéoles.However, one of the problems with the electrical outlet as described in the document US 7,549,874 B2 is that, in order to successfully assemble the socket, it is necessary to leave sufficient clearance between the receiving cells and their respective compartments in order to allow all the positioning dispersions resulting from the prior soldering of the cells to the printed circuit. Consequently, due to this excessive play between the cells and their respective compartments in the base, the cells cannot be precisely adjusted in their compartments and the performance of the former is degraded, in particular from the point of view of quality. contacts between plugs and sockets. In addition, the fixing of the cells in the compartments of the base is made difficult due to the prior soldering of the cells to the printed circuit, and the size of the assembly resulting therefrom, as well as the stress on the welds of the cells.

OBJECTIF DE L'INVENTIONOBJECTIVE OF THE INVENTION

La prise électrique de l'invention vise à remédier à tout ou partie des inconvénients de l'état de la technique et vise notamment à proposer une prise électrique munie d'alvéoles de réception reliées électriquement à un circuit imprimé, permettant un assemblage simple de la prise tout en présentant des performances améliorées pour les alvéoles.The electric socket of the invention aims to remedy all or part of the drawbacks of the state of the art and aims in particular to provide an electric socket provided with receiving cells electrically connected to a printed circuit, allowing simple assembly of the grip while exhibiting improved performance for the alveoli.

RESUME DE L'INVENTIONSUMMARY OF THE INVENTION

Cet objectif est atteint grâce à une prise électrique selon la revendication 1, comprenant entre autres:

  • un socle muni d'un logement intérieur, le logement intérieur du socle débouchant sur une ouverture centrale ;
  • un circuit imprimé agencé au sein du logement intérieur du socle ;
  • au moins deux alvéoles de réception d'une broche de contact électrique, chaque alvéole étant agencée au sein du logement intérieur du socle de sorte à être disposée en regard de l'ouverture centrale, et présentant une portion directement connectée (c'est-à-dire sans élément intermédiaire, par exemple par soudage) au circuit imprimé, chaque alvéole étant destinée à recevoir une broche de contact électrique d'une fiche électrique, et étant propre à enserrer cette broche de sorte à maintenir un contact électrique entre la broche et l'alvéole ;
dans laquelle la prise électrique comprend en outre une pièce monobloc de support et de réception des alvéoles agencée au sein du logement intérieur du socle, et des moyens de fixation amovible de la pièce monobloc au socle, ladite pièce monobloc définissant au moins deux compartiments de réception d'une alvéole, chaque alvéole étant fixée au sein d'un desdits compartiments.This objective is achieved by means of an electrical outlet according to claim 1, comprising among others:
  • a base provided with an interior housing, the interior housing of the base opening into a central opening;
  • a printed circuit arranged within the interior housing of the base;
  • at least two cells for receiving an electrical contact pin, each cell being arranged within the interior housing of the base so as to be disposed facing the central opening, and having a directly connected portion (i.e. - say without intermediate element, for example by welding) to the printed circuit, each cell being intended to receive an electrical contact pin of an electrical plug, and being able to grip this pin so as to maintain an electrical contact between the pin and the alveolus;
wherein the electrical outlet further comprises a single piece for supporting and receiving the cells arranged within the interior housing of the base, and means for removable fixing of the single piece to the base, said single piece defining at least two receiving compartments of a cell, each cell being fixed within one of said compartments.

Ainsi, grâce à la combinaison entre une pièce monobloc dédiée munie des compartiments de réception des alvéoles et des moyens de fixation amovible de cette pièce au sein du socle, la prise électrique selon l'invention permet avantageusement de pouvoir agencer et ajuster d'abord les alvéoles au sein des compartiments de la pièce monobloc, puis de connecter les alvéoles au circuit imprimé et enfin de fixer l'ensemble au sein du socle. Ainsi, les alvéoles sont facilement et précisément ajustées dans leurs compartiments respectifs, avec un jeu minimal entre les alvéoles et les compartiments. Les performances des alvéoles sont ainsi significativement améliorées. En outre, l'assemblage de la prise électrique selon l'invention est simple, précis et intuitif.Thus, thanks to the combination between a dedicated one-piece part provided with compartments for receiving the cells and means for removable fixing of this part within the base, the electrical outlet according to the invention advantageously makes it possible to be able to first arrange and adjust the cells within the compartments of the one-piece part, then to connect the cells to the printed circuit and finally to fix the assembly within the base. Thus, the cells are easily and precisely adjusted in their respective compartments, with minimal play between the cells and the compartments. The performance of the cells is thus significantly improved. In addition, the assembly of the electrical outlet according to the invention is simple, precise and intuitive.

Selon l'invention, les moyens de fixation amovible comportent au moins une butée de blocage sur le socle, et au moins une partie sur la pièce monobloc apte à coopérer avec la butée de blocage pour permettre une insertion en position de maintien ferme de la pièce monobloc au sein du socle, le socle présentant au moins une paroi intérieure, ladite paroi intérieure comportant ladite butée de blocage, ladite partie faisant saillie depuis une paroi extérieure de la pièce monobloc.According to the invention, the removable fixing means comprise at least one blocking stop on the base, and at least one part on the one-piece part able to cooperate with the blocking stop to allow insertion in the firm holding position of the part. one-piece within the base, the base having at least one interior wall, said interior wall comprising said locking stop, said part projecting from an exterior wall of the one-piece part.

Une telle configuration permet de faciliter la fixation de la pièce monobloc au sein du logement intérieur du socle. Par ailleurs, du fait du blocage ferme de la pièce monobloc au sein du socle, les sollicitations mécaniques successives que vont engendrer la mise en place et l'extraction de la fiche électrique dans la prise sont avantageusement supportées par le socle lui-même, et non plus par les portions des alvéoles connectées au circuit imprimé. Ainsi, le risque de détérioration de ces portions connectées des alvéoles, du à ces sollicitations mécaniques, est réduit.Such a configuration makes it possible to facilitate the fixing of the one-piece part within the interior housing of the base.

Each compartment 36 of the one-piece piece 12 is made with a spacing such that it allows an adjustment of the cell 10 within the compartment 36 guaranteeing optimum performance thereof. Thus, the cells 10 fit separately with precision within their respective compartments 36. At the end of this first step, the operator positions the printed circuit 8 on the one-piece part 12, as illustrated on figure 5 . To do this, the operator uses the pins 19 and inserts the latter into the orifices 54 of the printed circuit 8, in order to allow centering and positioning of the one-piece part 12 with respect to the printed circuit 8.

Au cours d'une étape suivante illustrée à la figure 5, l'opérateur connecte la portion de connexion 34 de chaque alvéole 10 au circuit imprimé 8. De préférence, cette étape de connexion est effectuée par brasure.During a next step illustrated in figure 5 , the operator connects the connection portion 34 of each cell 10 to the printed circuit 8. Preferably, this connection step is carried out by soldering.

Au cours d'une étape suivante, l'opérateur agence, au sein du logement intérieur 24 défini par le socle 6, l'ensemble formé du circuit imprimé 8 et de la pièce monobloc 12 équipée des alvéoles 10.During a next step, the operator arranges, within the interior housing 24 defined by the base 6, the assembly formed by the printed circuit 8 and the one-piece part 12 equipped with the cells 10.

Au cours d'une étape finale, l'opérateur fixe la pièce monobloc 12 au sein du logement intérieur 24 défini par le socle 6, de manière à ce que chaque alvéole de réception 10 soit disposée en regard de l'ouverture centrale 26. Pour ce faire, l'opérateur met en œuvre les moyens complémentaires 14, 46, 48 de fixation amovible de la pièce monobloc 12 au socle 6. L'opérateur peut ensuite par exemple finaliser l'assemblage de la prise électrique 1 en fermant l'ouverture centrale 26 par la fixation de la tête de prise 2 et du support d'appareillage 16 sur le socle 6.During a final step, the operator fixes the one-piece part 12 within the interior housing 24 defined by the base 6, so that each receiving cell 10 is placed opposite the central opening 26. For to do this, the operator implements the additional means 14, 46, 48 for removable fixing of the one-piece part 12 to the base 6. The operator can then for example finalize the assembly of the electrical outlet 1 by closing the central opening 26 by fixing the outlet head 2 and the appliance support 16 on the base 6.
