Description

La présente invention se rapporte aux prises de courant électrique et concerne plus particulièrement un dispositif permettant d'extraire aisément une fiche d'une prise de courant électrique standard dans laquelle elle a été positionnée.The present invention relates to electrical outlets and relates more particularly to a device for easily extracting a plug from a standard electrical outlet in which it has been positioned.

Pour la clarté et la compréhension aisée de la présente invention, on convient d'appeler :

  • prise de courant : l'élément comprenant les douilles ou pinces de contact généralement sous tension permanente ; cet élément constitue la partie dite "femelle" d'un connecteur et qui est généralement fixée au mur ;
  • fiche de courant : l'élément relié à l'appareil et comprenant les broches conductrices que l'on introduit dans les douilles ou pinces de contact pour assurer l'alimentation de l'appareil ; cet élément constitue la partie dite "mâle" d'un connecteur.
For clarity and easy understanding of the present invention, it should be called:
  • socket-outlet: the element comprising the sockets or contact clips generally under permanent tension; this element constitutes the so-called "female" part of a connector and which is generally fixed to the wall;
  • current plug: the element connected to the appliance and comprising the conductive pins which are inserted into the contact sockets or clamps to supply the appliance with power; this element constitutes the so-called "male" part of a connector.

Il est bien connu que les fiches ordinaires, bien qu'étant faciles à introduire dans une prise standard, sont par contre difficiles à extraire d'une telle prise. En effet, le seul moyen procuré à l'utilisateur est d'agripper la fiche par son extrémité comportant généralement le fil de courant électrique pour la tirer dans sa direction.It is well known that ordinary plugs, although being easy to insert into a standard socket, are however difficult to extract from such a socket. Indeed, the only means provided to the user is to grip the plug by its end generally comprising the electric current wire to pull it in its direction.

On comprend bien les difficultés de l'utilisateur : celui-ci n'a que peu d'appui pour exercer sa force et la surface de préhension de la fiche est relativement limitée ; en outre, l'ouverture des douilles ou l'écartement des pinces demeure constant pour assurer en permanence un contact électrique franc tandis que le diamètre des broches augmente en fonction de l'ampérage pour accroître les surfaces de contact entre les douilles ou pinces et les broches ; ceci pour éviter tout échauffement. On comprend donc aisément que l'extraction des fiches devienne de plus en plus difficile en fonction de l'augmentation de l'ampérage.We understand the difficulties of the user: he has little support to exert his force and the grip surface of the plug is relatively limited; in addition, the opening of the sockets or the spacing of the clamps remains constant to permanently ensure a frank electrical contact while the diameter of the pins increases according to the amperage to increase the contact surfaces between the sockets or clamps and the pins; this to avoid overheating. It is therefore easy to understand that the extraction of the cards becomes more and more difficult as a function of the increase in amperage.

Or, de telle fiches (ampérage de 4 à 10 Ampères) sont couramment utilisées pour des appareils ménagers tels qu'aspirateurs, friteuses, robots, etc...However, such plugs (amperage from 4 to 10 amps) are commonly used for household appliances such as vacuum cleaners, fryers, robots, etc.

De ce fait, lorsque l'utilisateur veut retirer une telle fiche, il a tendance à exercer le maximum de force sur la fiche sans retenir la prise, ce qui a le plus souvent pour effet d'arracher quelque peu la prise coopérant avec la fiche que l'on désire extraire.Therefore, when the user wants to remove such a plug, he tends to exert maximum force on the plug without retaining the plug, which most often has the effect of tearing the plug somewhat cooperating with the plug that we want to extract.

Force est de constater qu'après avoir retiré plusieurs fois une telle fiche d une prise, soit la prise est arrachée de son support, soit le câble électrique est arraché de la fiche, avec tous les inconvénients et notamment le risque d'électrocution qui en découlent.It must be noted that after having removed such a plug from a socket several times, either the plug is torn from its support, or the electric cable is torn from the plug, with all the disadvantages and in particular the risk of electric shock which arise.

On constate généralement que pour des jeunes ou des personnes âgées, l'extraction d'une fiche, même de faible ampérage, est une opération délicate.It is generally observed that for young people or the elderly, extracting a plug, even with a low amperage, is a delicate operation.

Tenant compte de l'utilisation abondante des fiches ordinaires du type décrit ci-dessus, il s'avère souhaitable de proposer un dispositif simple et efficace d'emploi, assurant pour un minimum d'effort l'extraction en toute sécurité d'une fiche de courant électrique de la prise standard dans laquelle elle a été positionnée, et ce, sans aucun dommage ni pour la prise ni pour la fiche et le câble qui y est connecté.Taking into account the abundant use of ordinary cards of the type described above, it is desirable to propose a simple and effective device for use, ensuring for a minimum of effort the safe extraction of a card current from the standard outlet in which it was positioned, without any damage to the outlet or the plug and cable connected to it.

Un tel dispositif aurait également l'avantage d'éliminer tout risque d'électrocution que court un utilisateur qui arracherait la prise de courant ou le câble électrique en s'efforçant d'extraire une fiche.Such a device would also have the advantage Eliminate any risk of electric shock to a user who tears off the electrical outlet or the electric cable while trying to extract a plug.

Le but de la présente invention est donc de remédier aux inconvénients précités en proposant un moyen simple, fiable et économique pour extraire une fiche de courant électrique en évitant tout arrachement de la prise dans laquelle elle a été positionnée et/ou du câble électrique.The object of the present invention is therefore to remedy the aforementioned drawbacks by proposing a simple, reliable and economical means for extracting an electric current plug while avoiding any tearing of the socket in which it has been positioned and / or of the electric cable.

Un second but de l'invention est de fournir l'agrément d'une commande simple et douce d'emploi.A second object of the invention is to provide the approval of a simple and easy-to-use command.

Un troisième but de l'invention est de fournir une commande unique permettant d'extraire la fiche de courant électrique de la prise coopérant avec elle, et d'une ergonomie telle que l'utilisateur ne soit pas tenté de saisir le câble électrique.A third object of the invention is to provide a single command making it possible to extract the electric current plug from the socket cooperating with it, and with ergonomics such that the user is not tempted to grasp the electric cable.

Un quatrième but de l'invention est de proposer une prise électrique munie d'un moyen d'extraction selon l'invention.A fourth object of the invention is to provide an electrical outlet provided with an extraction means according to the invention.

Un cinquième but de l'invention est de proposer une prise munie du dispositif selon l'invention, utilisant des éléments standards et déjà approuvés par les divers organismes de sécurité et/ou normalisation de façon à éviter des procédures administratives d'approbation.A fifth object of the invention is to propose a socket fitted with the device according to the invention, using standard elements and already approved by the various security and / or standardization organizations so as to avoid administrative approval procedures.

Un sixième but de l'invention est de proposer une plaquette de protection pour prise électrique munie du dispositif objet de l'invention et destinée ainsi à aisément remplacer les plaquettes de protection existantes.A sixth object of the invention is to propose a protective plate for an electrical outlet provided with the device which is the subject of the invention and thus intended to easily replace the existing protective plates.

En vue de la réalisation de ces buts, le dispositif objet de l'invention est essentiellement caractérisé par le contenu de la revendication principale.With a view to achieving these aims, the device which is the subject of the invention is essentially characterized by the content of the main claim.

Divers avantages et caractéristiques de l'invention ressortiront de la description détaillée d'un mode de réalisation préféré donné, ci-après, à titre non limitatif et pour lequel :

  • la figure 1 représente, en coupe, une prise de courant électrique standard vue de dessus et fixée dans une paroi,
  • la figure 2 représente, en vue éclatée, les principaux éléments constitutifs d'un dispositif d'extraction selon l'invention, appliqué à une prise de courant électrique,
  • la figure 3 représente, en coupe, une prise de courant électrique munie du dispositif d'extraction apparaissant à la figure 2 et en position inopérative,
  • la figure 4 représente le dispositif d'extraction de la figure 3 après actionnement de ce dernier.
Various advantages and characteristics of the invention will emerge from the detailed description of a preferred embodiment given below, without implied limitation and for which:
  • FIG. 1 represents, in section, a standard electrical outlet seen from above and fixed in a wall,
  • FIG. 2 represents, in exploded view, the main constituent elements of an extraction device according to the invention, applied to an electrical outlet,
  • FIG. 3 represents, in section, an electrical outlet fitted with the extraction device appearing in FIG. 2 and in the inoperative position,
  • Figure 4 shows the extraction device of Figure 3 after actuation of the latter.

Sur ces figures, on n'a représenté, dans un but de clarté, que les éléments nécessaires à la compréhension de l'invention et les éléments identiques portent les mêmes références.In these figures, for the sake of clarity, only the elements necessary for understanding the invention and the identical elements have been given the same references.

On a représenté à la figure 1, en coupe, le boîtier d'une prise 70 de courant électrique standard fixée dans une paroi. Elle comprend une plaquette de protection 71, deux douilles ou pinces de contact 72 sous tension permanente, servant à emprisonner les conducteurs de courant électrique 18 d'une fiche standard (figures 3 et 4)et une broche 74 représentant la "terre" et s'encastrant dans la connexion pratiquée dans le support 12 de toute fiche électrique.There is shown in Figure 1, in section, the housing of a standard electrical outlet 70 fixed in a wall. It includes a protective plate 71, two sockets or contact clamps 72 under permanent voltage, used to trap the electric current conductors 18 of a standard plug (Figures 3 and 4) and a pin 74 representing the "earth" and s embedded in the connection made in the support 12 of any electrical plug.

Il est intéressant de relever que la distance entre l'extrémité avant du rebord 80 de la plaquette de protection 71 et la surface avant du support 12 de la fiche 10 lorsqu'elle est positionnée dans la prise 70, reste identique quel que soit le type de prise utilisé (prise apparente, encastrée, volante, etc...) car elle est normalisée.It is interesting to note that the distance between the front end of the flange 80 of the protective plate 71 and the front surface of the support 12 of the plug 10 when it is positioned in the socket 70, remains identical whatever the type outlet used (exposed, embedded, flying, etc.) because it is standardized.

Le rebord 80 a une forme et un profil normalisés de telle sorte que le boîtier de la prise 70 n'accepte que des fiches répondant aux normes en vigueur.The rim 80 has a standardized shape and profile so that the socket housing 70 accepts only plugs which meet the standards in force.

D'une manière purement pratique, l'utilisateur raccorde l'appareil qu'il désire utiliser, muni de la fiche de courant électrique, comme il a l'habitude de le faire, simplement en introduisant à fond la fiche dans la prise 70.In a purely practical way, the user connects the device which he wishes to use, provided with the electric current plug, as he usually does, simply by inserting the plug fully into socket 70.

Comme représenté à la figure 2, la plaquette de protection 71 d'une prise 70 équipée du dispositif d'extraction selon l'invention comporte un rebord en forme d'anneau 80 dans lequel sont pratiquées trois fentes axiales 81 réparties de préférence à 120° l'une de l'autre.As shown in Figure 2, the protective plate 71 of a socket 70 equipped with the extraction device according to the invention has a ring-shaped rim 80 in which are made three axial slots 81 preferably distributed at 120 ° one from the other.

Ce rebord 80 reçoit un organe de poussée en forme de coupelle 90 dont la surface extérieure vient à proximité de la surface intérieure dudit rebord, la coupelle 90 étant munie de trois tétons 91 qui s'engagent dans les trois fentes 81 du rebord 80 de telle sorte que la coupelle 90 peut se déplacer par un mouvement axial relatif par rapport au rebord 80.This rim 80 receives a cup-shaped pushing member 90 whose outer surface comes close to the inner surface of said rim, the cup 90 being provided with three pins 91 which engage in the three slots 81 of the rim 80 of such so that the cup 90 can move by an axial movement relative to the rim 80.

Cette coupelle 90 comporte également deux ouvertures 92 correspondant aux ouvertures 82 pratiquées dans la plaquette de protection 71 pour permettre le passage des conducteurs 18 d'une fiche standard, tandis que l'ouverture 93 correspond à l'ouverture 83 permettant le passage de la broche 74 de "terre". Enfin, une ouverture 94 permet le passage d'une vis fixant la plaquette 71 à la prise 70 par l'intermédiaire de l'ouverture 84, et ce, d'une manière conventionnelle et donc non décrite.This cup 90 also has two openings 92 corresponding to the openings 82 made in the protective plate 71 to allow the passage of the conductors 18 of a standard plug, while the opening 93 corresponds to the opening 83 allowing the passage of the pin 74 of "earth". Finally, an opening 94 allows the passage of a screw fixing the plate 71 to the socket 70 via the opening 84, in a conventional manner and therefore not described.

Un élément de commande 100 de forme annulaire, monté à la périphérie extérieure du rebord 80 et guidé en rotation par celui-ci, comporte trois fentes inclinées 101, dans lesquelles s'engagent les tétons 91 de la coupelle 90, ainsi qu'un levier de commande 102. Un ressort 103, dont une extrémité est fixée audit levier de commande 102 et l'autre à un des tétons 91, assure le retour de l'élément de commande 100 en position de repos, position dans laquelle la coupelle 90 vient contre la surface de fond 73 de la plaquette 71 et permet donc à l'utilisateur de positionner une fiche standard dans la prise 70 (figure 3).A control element 100 of annular shape, mounted on the outer periphery of the flange 80 and guided in rotation by the latter, comprises three inclined slots 101, in which engage the pins 91 of the cup 90, as well as a lever 102. A spring 103, one end of which is fixed to said control lever 102 and the other to one of the pins 91, ensures the return of the control element 100 to the rest position, position in which the cup 90 comes against the bottom surface 73 of the plate 71 and therefore allows the user to position a standard plug in socket 70 (figure 3).

Deux plaquettes latérales 200 (figure 2) assurent le guidage et le maintien de l'élément de commande 100.Two lateral plates 200 (FIG. 2) guide and maintain the control element 100.

Une fiche standard comporte un corps 10 sensiblement cylindrique dont la forme et le profil lui permettent d'être introduit dans toute prise standard notamment dans les pays de la CEE et un support 12 auxquels sont fixés des conducteurs de courant 18 assurant la transmission d'énergie électrique et une connexion dite de "terre".A standard plug has a substantially cylindrical body 10 whose shape and profile allow it to be inserted into any standard socket, especially in EEC countries, and a support 12 to which are fixed current conductors 18 ensuring the transmission of energy. electrical and a so-called "earth" connection

Lorsque l'utilisateur souhaite retirer la fiche de la prise 70, il lui suffit de simplement actionner l'élément de commande 100 à l'aide du levier 102 dans le sens indiqué par la flèche F1.When the user wishes to remove the plug from the socket 70, he simply has to actuate the control element 100 using the lever 102 in the direction indicated by the arrow F1.

En effet, la rotation de l'élément de commande 100 et donc le déplacement des fentes 101 assurent le déplacement des tétons 91 le long des fentes 81 et donc un déplacement axial de la coupelle 90 par rapport à la prise 70 (figure 4). Comme le fond de la coupelle 90 vient s'appuyer en exerçant une force axiale sur la surface frontale du support 12 de la fiche électrique, celle-ci est alors déplacée axialement dans le sens de la flèche F2 et la fiche est donc retirée de la prise. Lorsque l'utilisateur relâche le levier 102, le ressort 103 ramène l'élément de commande en position de repos ; la coupelle 90 est alors ramenée vers la surface de fond 73 de la prise dans laquelle peut alors être positionnée toute fiche électrique standard.Indeed, the rotation of the control element 100 and therefore the displacement of the slots 101 ensure the movement of the pins 91 along the slots 81 and therefore an axial displacement of the cup 90 relative to the socket 70 (Figure 4). As the bottom of the cup 90 comes to bear by exerting an axial force on the front surface of the support 12 of the electrical plug, the latter is then moved axially in the direction of the arrow F2 and the plug is therefore removed from the taken. When the user releases the lever 102, the spring 103 returns the control element to the rest position; the cup 90 is then brought back to the bottom surface 73 of the socket in which any standard electrical plug can then be positioned.

Bien entendu, cet organe de poussée en forme de coupelle 90 peut avoir toute autre forme (cylindrique, annulaire, triangulaire,...) du moment qu'elle coopère avec le support 12 de la fiche pour assurer l'extraction de la fiche tout en permettant le passage des conducteurs 18 et de la broche 74.Of course, this cup-shaped pushing member 90 can have any other shape (cylindrical, annular, triangular, ...) as long as it cooperates with the support 12 of the plug to ensure the extraction of the plug while by allowing the passage of the conductors 18 and the pin 74.

Comme les plaquettes de protection 71 des prises de courant sont des éléments standards et normalisés, on peut envisager de mettre sur le marché une plaquette 71 munie du dispositif selon l'invention telle que représenté à la figure 2, l'utilisateur pouvant alors facilement remplacer toute plaquette existante par une plaquette 71.Like the protective pads 71 of the sockets current are standard and standardized elements, it is conceivable to market a wafer 71 provided with the device according to the invention as shown in FIG. 2, the user then being able to easily replace any existing wafer with a wafer 71.

Comme on le comprend aisément, le dispositif objet de l'invention assure l'extraction d'une fiche électrique tout en exerçant sur le boîtier de la prise une force opposée de façon à maintenir cette prise immobile et donc lui éviter toute possibilité d'arrachement. D'autre part, aucune traction n'est exercée à aucun moment sur le câble électrique.As can easily be understood, the device which is the subject of the invention ensures the extraction of an electrical plug while exerting on the socket casing an opposite force so as to keep this socket immobile and therefore to avoid any possibility of it being torn off. . On the other hand, no traction is exerted at any time on the electric cable.

Ainsi qu'on le constate, le retrait de la fiche de courant, grâce au dispositif objet de l'invention, ne demande qu'un minimum d'effort et à aucun moment l'utilisateur ne peut arracher la prise ou le câble électrique.As can be seen, the withdrawal of the current plug, thanks to the device which is the subject of the invention, requires only a minimum of effort and at no time can the user tear off the plug or the electric cable.

Ainsi qu'on le constate, le dispositif objet de l'invention, non seulement facilite l'extraction de fiches mais simultanément il garantit une plus grande sécurité à l'utilisateur puisqu'il élimine toute force d'arrachement transmise à la prise électrique, assurant ainsi l'immobilité de celle-ci, des douilles de contact, des conducteurs électriques et de son boîtier d'encastrement.As can be seen, the device which is the subject of the invention not only facilitates the extraction of plugs but simultaneously it guarantees greater security for the user since it eliminates any tearing force transmitted to the electrical outlet, thus ensuring the immobility of the latter, of the contact sockets, of the electrical conductors and of its installation housing.

En outre, aucune traction n'est exercée sur la câble électrique lors de l'extraction de la fiche de courant, ce qui est également un gage supplémentaire de sécurité.In addition, no traction is exerted on the electric cable during the extraction of the current plug, which is also an additional guarantee of safety.

D'autre part, selon les mesures effectuées, si l'extraction d'une fiche standard de 10 ampères requiert en moyenne une force comprise entre 4 et 5 kilos, la même fiche, grâce au dispositif objet de l'invention est retirée de la prise à l'aide d'une force moyenne de 1,5 kilo.On the other hand, according to the measurements carried out, if the extraction of a standard 10-amp plug requires on average a force of between 4 and 5 kilos, the same plug, thanks to the device that is the subject of the invention, is removed from the taken with an average force of 1.5 kilo.

Le mode de réalisation décrit se rapporte à des prises et des fiches pour usage domestique (normes NBN C 61-112-1/CEB) mais il faut noter que le dispositif objet de l'invention peut s'appliquer à tout autre type de prise et notamment des prototypes ont été réalisés pour celles mises en oeuvre aux Etats-Unis, en Grande-Bretagne, ainsi que pour les prises à usage industriel, telles celles couvertes par les normes IEC 309-2.The embodiment described relates to sockets and plugs for domestic use (NBN C 61-112-1 / CEB standards) but it should be noted that the device which is the subject of the invention can be applied to any other type of socket and in particular prototypes have been produced for those implemented in the United States, Great Britain, as well as for sockets for industrial use, such as those covered by the IEC 309-2 standards.

Bien que l'angle préféré des fentes soit de l'ordre de 30° pour apporter un avantage mécanique et un rapport de force 3 : 1, cet angle peut bien entendu varier selon l'application particulière et la force d'extraction à produire. En pratique, pour les différents prototypes réalisés, cet angle varie entre 20° et 40° en fonction du déplacement voulu et de la force requise.Although the preferred angle of the slots is of the order of 30 ° to provide a mechanical advantage and a 3: 1 force ratio, this angle can of course vary depending on the particular application and the extraction force to be produced. In practice, for the various prototypes produced, this angle varies between 20 ° and 40 ° depending on the desired displacement and the force required.

Il est à noter qu'avec le dispositif objet de l'invention, les normes de maintien des conducteurs sont toutes respectées et que c'est la seule extraction des fiches qui est grandement facilitée.It should be noted that with the device which is the subject of the invention, the standards for maintaining the conductors are all respected and that it is the only extraction of the plugs which is greatly facilitated.

De plus, tandis que dans la réalisation décrite, l'angle des fentes est droit, leurs surfaces peuvent être curvilignes pour que la force manuelle exercée lors du retrait d'une prise soit pratiquement constante. Dans ce cas, la surface est peu inclinée dans sa première moitié, correspondant à la force requise pour le retrait des conducteurs de l'emprise des douilles et qui requiert un effort important, alors qu'elle est plus inclinée dans la seconde moitié de son mouvement, qui correspond au retrait final de la fiche de la prise, et donc à un effort moins important.In addition, while in the embodiment described, the angle of the slots is straight, their surfaces can be curved so that the manual force exerted during the withdrawal of a grip is practically constant. In this case, the surface is slightly inclined in its first half, corresponding to the force required for the withdrawal of the conductors from the grip of the sockets and which requires significant effort, while it is more inclined in the second half of its movement, which corresponds to the final withdrawal of the plug from the socket, and therefore to a less significant effort.

D'autre part, si dans la description ci-dessus la prise 70 est toujours représentée fixée dans une paroi, il faut noter qu'elle peut être indépendante (cas des rallonges électriques), le dispositif objet de l'invention conservant tous ses avantages.On the other hand, if in the above description the socket 70 is always shown fixed in a wall, it should be noted that it can be independent (case of electrical extension cords), the device object of the invention retaining all its advantages .
