Description

Domaine de l'inventionField of the invention

L'invention se rapporte à des prises de courant rotatives.The invention relates to rotary sockets.

L'invention se rapporte aussi à des blocs d'alimentation comprenant de telles prises rotatives.The invention also relates to power supplies comprising such rotary plugs.

État de la techniqueState of the art

Afin d'éviter que le consommateur exerce une traction directement sur le câble d'alimentation d'appareils électriques, ce qui, à la longue, provoque la rupture des fils conducteurs, de plus en plus d'appareils sont munis de fiches formant un angle avec le câble d'alimentation. Le problème, c'est que ces fiches sont évidemment plus encombrantes, et, notamment dans le cas de prises multiples, les différentes fiches risquent de se gêner mutuellement. Ce problème se pose également avec le branchement de blocs d'alimentation combinant une fiche et une alimentation pour rasoirs, téléphone mobile, ordinateurs, etc.In order to prevent the consumer pulling directly on the power supply cable of electrical devices, which in the long run causes the breaking of the wires, more and more devices are provided with plugs forming an angle with the power cable. The problem is that these cards are obviously more cumbersome, and especially in the case of multiple plugs, the different cards may interfere with each other. This problem also arises with the connection of power supplies combining a plug and a power supply for razors, mobile phone, computers, etc.

Le document US2011/0312194 A1 dévoile un boitier multiprise muni d'inserts de prises munis d'une partie mobile en rotation et d'une partie fixe solidaire du boitier. La partie mobile est équipée de fils flexibles qui traversent un trou se trouvant dans la partie fixe et qui sont reliés électriquement aux lignes de raccordement électrique présentes à l'intérieur du boitier. Des butées limitent l'amplitude de la rotation. Le dispositif dévoilé par US2011/0312194 A1 présente néanmoins des faiblesses au niveau des connections électriques entre les fils flexibles et les lignes de raccordement électriques dans le boitier et les contacts d'enfichage. En effet, lors de la rotation de l'insert de prise, des sollicitations mécaniques sont exercées sur ces connections électriques, ce qui, à la longue, entraîne la rupture de ces connections.The document US2011 / 0312194 A1 reveals a socket housing with plug inserts provided with a rotatable portion and a fixed portion secured to the housing. The moving part is equipped with flexible wires which pass through a hole in the fixed part and which are electrically connected to the electrical connection lines present inside the housing. Stoppers limit the amplitude of the rotation. The device unveiled by US2011 / 0312194 A1 nevertheless presents weaknesses in the electrical connections between the flexible wires and the electrical connection lines in the housing and the plug contacts. Indeed, during the rotation of the plug insert, mechanical stresses are exerted on these electrical connections, which, in the long run, causes the breakage of these connections.

On connait du document EP0768737 A1 un bloc de prises muni d'inserts de prise rotatifs équipés de fils flexibles. Ces fils flexibles assurent la connexion entre les pôles de raccordement électrique du bloc et les manchons des inserts de prise destinés à recevoir les broches de fiches électriques. La prise de terre de chaque insert est également raccordée au pôle correspondant du bloc par l'intermédiaire de fils flexibles. Dans le dispositif décrit par EP0768737 A1 , les manchons et la prise de terre de chaque insert ne sont pas reliés directement aux pôles correspondants du bloc, mais le raccordement électrique est effectué par une interconnexion entre les manchons (et les prises de terre) des différents inserts de prise via des fils flexibles. Pour que chaque insert de prise puisse avoir un mouvement rotatif indépendant, il est nécessaire que les fils de raccordement aient une longueur considérablement plus importante que la distance directe entre deux inserts de prise adjacents.We know of the document EP0768737 A1 a socket block with rotating plug inserts with flexible wires. These flexible wires provide the connection between the electrical connection poles of the block and the sleeves of the plug inserts for receiving the pins of electrical plugs. The grounding of each insert is also connected to the corresponding pole of the block by means of flexible wires. In the device described by EP0768737 A1 , the sleeves and the grounding of each insert are not connected directly to the corresponding poles of the block, but the electrical connection is made by an interconnection between the sleeves (and the earth) of the various plug inserts via flexible wires . In order for each socket insert to have independent rotational movement, it is necessary for the connecting wires to be considerably longer in length than the direct distance between two adjacent socket inserts.

EP0702433A2 dévoile également un bloc de prises muni d'inserts de prise rotatifs, la rotation des inserts étant cette fois rendue possible par un agencement de contacts glissants entre des patins solidaires des inserts de prise et des sections d'anneau de frottement. Un tel système offre une plage limitée d'angles possibles pour les inserts de prise. EP0702433A2 also discloses a socket block provided with rotary plug inserts, the rotation of the inserts being this time made possible by an arrangement of sliding contacts between pads integral with the setting inserts and friction ring sections. Such a system provides a limited range of possible angles for the plug inserts.

CN201781169 dévoile un système dans lequel la connexion électrique entre les inserts de prise et les pôles de raccordement du bloc est effectuée par un contact entre deux plaques conductrices et les surfaces externes des inserts de prise. Un tel système ne permet pas de raccorder une prise de terre aux inserts de prise. CN201781169 discloses a system in which the electrical connection between the tap inserts and the terminal poles of the block is effected by contact between two conductive plates and the outer surfaces of the tap inserts. Such a system does not allow to connect a ground to the plug inserts.

Résumé de l'inventionSummary of the invention

Un but de l'invention est de permettre un branchement aisé de plusieurs fiches électriques sur un même bloc de prises, par une rotation adéquate de chaque insert de prise connecté à une fiche électrique, de façon à éviter que des fiches contigües ne se gênent mutuellement.An object of the invention is to allow easy connection of several electrical plugs on the same socket block, by a suitable rotation of each socket insert connected to an electrical plug, so as to prevent contiguous plugs interfering with each other .

Un autre but de l'invention est de fournir un bloc de prises rotatives robuste dont le mécanisme peut être sollicité de très nombreuses fois sans entrainer d'endommagement de sa structure et en ne mettant pas en danger les utilisateurs.Another object of the invention is to provide a block of robust rotary plugs whose mechanism can be solicited many times without causing damage to its structure and not endangering users.

L'objet de l'invention est une prise de courant rotative comprenant une base et une partie mobile comprenant une cuvette de protection et apte à pivoter en rotation par rapport à la base, des moyens mécaniques pour limiter l'amplitude de la rotation, ladite base étant munie d'un passage, ladite partie mobile étant également munie d'un passage et d'une pluralité d' alvéoles conductrices aptes à recevoir les broches d'une fiche électrique mâle, des moyens de fixation aptes à solidariser la base avec un support, des fils électriques flexibles entourés d'une gaine isolante et électriquement raccordés auxdites alvéoles conductrices, lesdits fils électriques flexibles traversant ledit passage de ladite partie mobile et ledit passage de ladite base,The object of the invention is a rotary socket comprising a base and a movable part comprising a protective bowl and able to pivot in rotation relative to the base, mechanical means for limiting the amplitude of rotation, said base being provided with a passage, said movable portion being also provided with a passage and a plurality of conductive cells able to receive the pins of a male electrical plug, fixing means adapted to secure the base with a support, flexible electrical wires surrounded by an insulating sheath and electrically connected to said conducting cells, said flexible electrical wires passing through said passage of said movable portion and said passage of said base,

la prise de courant rotative comprenant également

  • des plots conducteurs sur ladite base, lesdits fils électriques étant électriquement connectés auxdits plots;
  • des moyens de calage sur la base et sur la partie mobile en rotation aptes à enserrer les extrémités des fils électriques flexibles, les passages étant disposés dans l'axe de rotation de ladite partie mobile, les dimensions et la forme de ces passages étant telles qu'ils empêchent tout déplacement de la partie centrale des fils flexibles.
the rotating power socket also including
  • conductive pads on said base, said electrical wires being electrically connected to said pads;
  • means for wedging on the base and on the rotatable part adapted to grip the ends of the flexible electrical wires, the passages being arranged in the axis of rotation of said movable part, the dimensions and the shape of these passages being such that they prevent any displacement of the central part of the flexible wires.

L'avantage de cette conception est qu'elle réduit, voire annule les sollicitations mécaniques exercées sur les connections électriques.The advantage of this design is that it reduces or even cancels the mechanical stresses exerted on the electrical connections.

Les passages dans la base et la partie mobile peuvent présenter différentes sections, dans la mesure où les parties centrales des fils conducteurs sont immobilisées efficacement.The passages in the base and the movable portion may have different sections, to the extent that the central portions of the conductive son are immobilized effectively.

Suivant un mode de réalisation avantageux, les passages dans la base et la partie mobile présentent une section circulaire. Cette forme pour la section est particulièrement adaptée à des fils électriques flexibles de section circulaire.According to an advantageous embodiment, the passages in the base and the movable portion have a circular section. This shape for the section is particularly suitable for flexible electrical son of circular section.

Suivant un mode de réalisation avantageux, les passages de section circulaire possèdent un diamètre tel qu'ils enserrent étroitement les fils électriques de manière à maintenir leur portion centrale sensiblement immobile.According to an advantageous embodiment, the passages of circular section have a diameter such that they closely enclose the electrical son to maintain their central portion substantially immobile.

Suivant un mode de réalisation avantageux, les contacts électriques des parties fixes et mobiles sont disposés à l'opposé les uns des autres, c'est-à-dire que les connexions électriques entre les fils électriques flexibles et les alvéoles conductrices sont effectuées au niveau de la partie supérieure de la partie mobile tandis que les connexions entre les fils flexibles et les plots conducteurs sont effectuées au niveau de la partie inférieure de la base. Cette configuration pour les contacts électriques permet d'allonger la portion des fils électriques flexibles sensiblement parallèle à l'axe de rotation de la partie mobile.According to an advantageous embodiment, the electrical contacts of the fixed and mobile parts are arranged opposite each other, that is to say that the electrical connections between the flexible electrical wires and the conducting cells are made at the of the upper part of the movable part while the connections between the flexible wires and the conductive pads are made at the bottom of the base. This configuration for the electrical contacts makes it possible to lengthen the portion of the flexible electrical wires substantially parallel to the axis of rotation of the mobile part.

Selon un mode de réalisation avantageux, la prise de courant selon l'invention est munie en outre d'un dispositif de sécurité empêchant l'utilisateur d'accéder indument aux alvéoles conductrices (sécurité « enfant »). Un tel dispositif peut revêtir différents modes de réalisation, l'objectif étant à chaque fois de prévenir un accès inopiné aux alvéoles conductrices qui pourrait entrainer des désagréments tels qu'une électrocution.According to an advantageous embodiment, the socket according to the invention is further provided with a safety device preventing the user from indiscriminately accessing the conducting cells ("child" safety). Such a device can take different embodiments, the objective being each time to prevent unexpected access to the conductive cells that could cause inconvenience such as electrocution.

Selon un mode de réalisation avantageux, les connexions électriques sont réalisées par soudage.According to an advantageous embodiment, the electrical connections are made by welding.

Selon un mode de réalisation avantageux, les fils électriques flexibles sont sertis à leurs deux extrémités. Le sertissage est une alternative avantageuse au soudage car il garantit une durée de vie rallongée et élimine le point faible résultant de températures élevées dans le cas du soudage.According to an advantageous embodiment, the flexible electrical son are crimped at both ends. Crimping is an advantageous alternative to welding because it guarantees an extended service life and eliminates the low point resulting from high temperatures in the case of welding.

Selon un mode de réalisation avantageux, les connexions électriques sont réalisées par vissage.According to an advantageous embodiment, the electrical connections are made by screwing.

Un autre objet de l'invention est un bloc multiprise comprenant au moins une prise de courant rotative selon la description ci-dessus. Le nombre total de prises de courant rotatives présentes sur le bloc multiprise dépend des besoins de l'utilisateur.Another object of the invention is a power strip comprising at least one rotary power socket according to the description above. The total number of rotary power outlets on the power strip depends on the needs of the user.

Selon un mode de réalisation avantageux, le bloc multiprise est muni à la fois de prises rotatives selon la présente invention et de prises classiques non-rotatives. Il n'est en effet pas essentiel dans certains cas que toutes les prises du bloc multiprise soient rotatives et le nombre de prises rotatives peut être restreint dans le but de réduire les coûts, une prise rotative étant plus chère à la conception qu'une prise classique. L'emplacement des prises rotatives peut être choisi de diverses manières.According to an advantageous embodiment, the power strip is provided with both rotary sockets according to the present invention and conventional non-rotating sockets. It is indeed not essential in some cases that all power strip sockets are rotatable and the number of rotating sockets can be restricted in order to reduce costs, a rotary socket being more expensive to design than a socket classic. The location of the rotary plugs can be chosen in various ways.

Selon un mode de réalisation avantageux, les prises rotatives se trouvent aux deux extrémités du bloc multiprise.According to an advantageous embodiment, the rotary plugs are at both ends of the power strip.

Selon un autre mode réalisation avantageux, les prises rotatives se trouvent en alternance avec des prises classiques sur le bloc multiprise, cela permettant de réduire la gêne mutuelle engendrée par chaque paire de fiches contigües.According to another advantageous embodiment, the rotary sockets are alternating with conventional sockets on the power strip, thereby reducing the mutual annoyance generated by each pair of contiguous plugs.

Un autre objet de l'invention est un bloc de prises de courant apte à être intégré dans un mur comprenant au moins une prise de courant selon la description ci-dessus. Comme dans le cas du bloc multiprise, un bloc de prises muni à la fois de prises rotatives selon la présente invention et de prises classiques non-rotatives peut être réalisé. L'emplacement des prises rotatives peut être choisi de diverses manières.Another object of the invention is a socket block adapted to be integrated into a wall comprising at least one socket as described above. As in the case of the power strip, a socket block with both rotating sockets according to the present invention and conventional non-rotating sockets can be realized. The location of the rotary plugs can be chosen in various ways.

Description détaillée de modes de réalisation particuliersDetailed description of particular embodiments

La figure 1 est une vue en éclatement de la partie inférieure de la prise rotative selon un mode de réalisation de l'invention. Les fils électriques flexibles ne sont pas représentés sur cette figure. La partie supérieure de la prise rotative, constituée d'une cuvette de protection 22, n'est pas représentée ici mais est visible à la Fig. 4. Une partie 2, mobile en rotation, s'insère dans une base 4. Un passage 6 traverse la partie mobile 2 en son centre (qui correspond à son axe de rotation) et un passage 8 correspondant traverse la base 4. La partie mobile 2 comprend des alvéoles conductrices 10 aptes à recevoir les broches d'une fiche électrique mâle. Une tige conductrice 12 permettant un raccordement électrique à une prise de terre est également présente sur la partie mobile 2. Des moyens de calage 14 destinés à enserrer les extrémités des fils électriques connectées aux alvéoles conductrices 10 sont situés à proximité immédiate des alvéoles. Des moyens mécaniques 15, 16 pour limiter l'amplitude de la rotation entre la partie 2, mobile en rotation, et la base 4 sont présents.The figure 1 is an exploded view of the lower part of the rotary socket according to one embodiment of the invention. Flexible electrical wires are not shown in this figure. The upper part of the rotating plug, consisting of a protective bowl 22, is not shown here but is visible at the Fig. 4 . A portion 2, movable in rotation, is inserted into a base 4. A passage 6 passes through the movable portion 2 at its center (which corresponds to its axis of rotation) and a corresponding passage 8 passes through the base 4. The moving part 2 comprises conductive cells 10 adapted to receive the pins of a male electrical plug. A conductive rod 12 for an electrical connection to a ground is also present on the movable portion 2. Clamping means 14 for gripping the ends of the electrical son connected to the conductive cells 10 are located in close proximity to the cells. Mechanical means 15, 16 for limiting the amplitude of rotation between the portion 2, rotatable, and the base 4 are present.

La figure 2 est une vue en éclatement de la partie inférieure de la prise rotative selon un autre mode de réalisation de l'invention. Ce mode de réalisation correspond au standard allemand utilisé pour les prises de courant, communément appelé « schuko ». La différence par rapport au mode de réalisation précédent tient à la structure de raccordement de la prise de terre qui dans ce dernier cas consiste non plus en une tige conductrice 12 mais en une paire de languettes latérales 13. Les éléments semblables communs entre le mode de réalisation de la figure 1 et celui de la figure 2 sont dénotés par des références semblables.The figure 2 is an exploded view of the lower part of the rotary socket according to another embodiment of the invention. This embodiment corresponds to the German standard used for sockets, commonly called "schuko". The difference compared to the previous embodiment is due to the connection structure of the earth electrode which in the latter case is no longer a conductive rod 12 but a pair of side tongues 13. The similar elements common between the embodiment of the figure 1 and that of the figure 2 are denoted by similar references.

La figure 3 montre le dessus de la partie rotative. Les éléments de la partie rotative décrits dans le premier paragraphe apparaissent de manière plus détaillée sur cette figure.The figure 3 shows the top of the rotating part. The elements of the rotating part described in the first paragraph appear in more detail in this figure.

La figure 4 montre le dessous de la prise rotative. La base 4 est munie de plots conducteurs 17. Des moyens de calage 18 aptes à enserrer les extrémités des fils électriques connectées aux plots conducteurs 17 sont également présents sur la base 4. Le passage 8 présente une forme circulaire et son diamètre est tel qu'il enserre étroitement à frottement doux les fils électriques (non apparents sur cette figure) le traversant de façon à les maintenir sensiblement immobiles lors de la rotation de la partie rotative 2. On notera que le passage 8 peut présenter différentes sections, dans la mesure où les fils conducteurs sont maintenus de la même façon.The figure 4 shows the bottom of the rotary socket. The base 4 is provided with conductive pads 17. Stalling means 18 adapted to grip the ends of the electrical wires connected to the conductive pads 17 are also present on the base 4. The passage 8 has a circular shape and its diameter is such that it tightly tightly grips the electrical wires (not visible in this figure) passing therethrough so as to keep them substantially immobile during the rotation of the rotary portion 2. It will be noted that the passage 8 may have different sections, to the extent that the conductors son are maintained in the same way.

La figure 5 est une vue en éclatement d'une prise rotative selon l'invention. Sur cette figure, on peut voir la cuvette de protection 22, constituée d'une couronne prévenant le contact avec une partie sous tension et d'un fond perforé pour le passage des broches. Cette cuvette est solidaire de la partie mobile en rotation 2. Afin d'éviter tout incident d'électrocution qui pourrait survenir si un utilisateur entrait indument en contact une des alvéoles conductrices 10, un dispositif de sécurité peut être intégré à cette cuvette 22 (« sécurité enfant »).The figure 5 is an exploded view of a rotary socket according to the invention. In this figure, we can see the protective bowl 22, consisting of a ring preventing contact with a live part and a perforated bottom for the passage of the pins. This bowl is integral with the movable part in rotation 2. In order to avoid any electrocution incident that could occur if a user improperly contacted one of the cells 10, a safety device can be integrated in this bowl 22 ("child safety").

La figure 6 montre plus en détails la zone de la partie 2 où sont connectés électriquement les fils conducteurs 24. Les connexions électriques 26 sont réalisées par soudure. Dans d'autres modes de réalisations, les connexions électriques peuvent être réalisées par sertissage. Cette figure met en évidence l'effet des moyens de calage 14 sur les fils conducteurs 24. Les moyens de calage 14 enserrent les extrémités des fils conducteurs 24 de façon à réduire fortement voire supprimer toute sollicitation mécanique au niveau des connexions électriques 26 lors d'une rotation de la partie mobile. L'angle formé par chaque fil conducteur au niveau du passage 6 participe aussi à la suppression des sollicitations mécaniques exercées sur les connexions électriques lorsque la partie 2 effectue un mouvement de rotation par rapport à la base 4. Ceci est particulièrement important lorsque les contacts sont soudés car les soudures sont des liaisons rigides très sensibles aux contraintes mécaniques.The figure 6 shows in more detail the zone of the part 2 where the conductive wires 24 are electrically connected. The electrical connections 26 are made by welding. In other embodiments, the electrical connections can be made by crimping. This figure highlights the effect of the wedging means 14 on the conductive wires 24. The wedging means 14 enclose the ends of the conductor wires 24 so as to reduce strongly or even eliminate any mechanical stress at the electrical connections 26 when a rotation of the moving part. The angle formed by each conductor wire at the passage 6 also contributes to the elimination of the mechanical stresses exerted on the electrical connections when the part 2 makes a rotational movement with respect to the base 4. This is particularly important when the contacts are welded because the welds are rigid connections very sensitive to mechanical stresses.

La figure 7 montre plus en détails la zone de la base 4 où sont connectés électriquement les fils conducteurs 24. Tout comme sur la partie 2, des moyens de calage 18 enserrent les extrémités des fils conducteurs 24 en vue de réduire voire supprimer toute sollicitation mécanique au niveau des connexions électriques 28. A nouveau, l'angle formé par chaque fil conducteur au niveau du passage 8 participe aussi à la suppression des sollicitations mécaniques exercées sur les connexions électriques lorsque la partie 2 effectue un mouvement de rotation par rapport à la base 4. On remarquera que les contacts électriques des parties fixes et mobiles sont disposés à l'opposé les uns des autres, c'est-à-dire que les connexions électriques entre les fils électriques flexibles 24 et les alvéoles conductrices 10 sont effectuées au niveau de la partie supérieure de la partie mobile 2 tandis que les connexions entre les fils flexibles 24 et les plots conducteurs 17 sont effectuées au niveau de la partie inférieure de la base 4. Cette configuration pour les contacts électriques permet d'allonger la portion des fils électriques flexibles sensiblement parallèle à l'axe de rotation de la partie mobile 2.The figure 7 shows in more detail the zone of the base 4 where the electrically conductive wires 24 are electrically connected. Like in the part 2, the wedging means 18 enclose the ends of the conductive wires 24 in order to reduce or even eliminate any mechanical stress at the level of the wires. Electrical connections 28. Again, the angle formed by each conductor wire at the passage 8 also contributes to the elimination of the mechanical stresses exerted on the electrical connections when the part 2 makes a rotational movement with respect to the base 4. It will be noted that the electrical contacts of the fixed and mobile parts are arranged opposite each other, that is to say that the electrical connections between the flexible electrical wires 24 and the conducting cells 10 are made at the level of the upper part of the movable part 2 while the connections between the flexible wires 24 and the conductive pads 17 are made at the lower part of the base 4. This configuration for the electrical contacts makes it possible to lengthen the portion flexible electrical wires substantially parallel to the axis of rotation of the movable part 2.

La figure 8 est une vue en éclatement d'un bloc multiprise 30 muni de prises rotatives telles que décrites à la figure 4. Ce bloc multiprise est muni de deux prises électriques rotatives et de deux prises fixes classiques.The figure 8 is an exploded view of a multi-jack unit 30 provided with rotary jacks as described in FIG. figure 4 . This power strip is equipped with two rotating electrical sockets and two standard fixed sockets.
