Description

DOMAINE TECHNIQUE DE L'INVENTIONTECHNICAL FIELD OF THE INVENTION

L'invention est relative à un ensemble de prises électriques comportant une fiche et un socle électriques adaptés pour collaborer l'un à l'autre de façon amovible. Ladite fiche électrique comporte au moins deux pistes électriques et ledit socle comporte au moins deux contacts électriques mobiles pouvant se déplacer entre une position interne et une position externe audit socle.The invention relates to a set of electrical sockets comprising an electrical plug and a base adapted to collaborate with each other removably. Said electrical plug comprises at least two electrical tracks and said base comprises at least two movable electrical contacts able to move between an internal position and a position external to said base.

En outre, l'ensemble de prises électriques comprend des moyens magnétiques de commande comportant un premier aimant intégré dans la fiche, et un élément magnétique mobile intégré au socle et solidaire des contacts électriques. Le premier aimant générant un flux magnétique de commande attirant l'élément magnétique mobile et déplaçant les contacts électriques entre la position interne et la position externe.In addition, the set of electrical outlets comprises magnetic control means comprising a first magnet integrated in the plug, and a movable magnetic element integrated in the base and secured to the electrical contacts. The first magnet generates a control magnetic flux attracting the movable magnetic element and displacing the electrical contacts between the internal position and the external position.

ETAT DE LA TECHNIQUE ANTERIEURESTATE OF THE PRIOR ART

L'utilisation de moyens magnétiques de positionnement d'une fiche électrique sur un socle électrique est connue.The use of magnetic means for positioning an electrical plug on an electrical base is known.

En effet, le document US7066739 décrit un ensemble de prises électriques comportant une fiche et un socle ayant respectivement des pistes électriques annulaires destinées à venir en contact les unes des autres sous l'action de moyens magnétiques. L'utilisation de pistes électriques annulaires autorise un positionnement angulaire indifférencié/à l'aveugle de la fiche sur le socle.Indeed, the document US7066739 discloses a set of electrical sockets having a plug and a base respectively having annular electric tracks intended to come into contact with each other under the action of magnetic means. The use of annular electric tracks allows undifferentiated / blind angular positioning of the plug on the base.

La force de commande des moyens magnétiques de l'ensemble de prises électriques est suffisante pour exercer une attraction de la fiche sur le socle lorsque cette dernière est positionnée dans un environnement proche du socle. En outre, la force de commande permet aussi de maintenir la fiche sur le socle en position connectée.The control force of the magnetic means of the set of electrical outlets is sufficient to exert an attraction of the plug on the base when the latter is positioned in an environment close to the base. In addition, the control force also keeps the plug on the base in the connected position.

Le document EP2128936 décrit aussi l'utilisation de moyens magnétiques pour le positionnement et le maintien d'une fiche sur un socle électrique. Comme pour le document US3521216 , les moyens magnétiques sont aussi aptes à déplacer des contacts électriques du socle électrique de manière à assurer une liaison électrique entre la fiche électrique et le socle.The document EP2128936 also describes the use of magnetic means for positioning and maintaining a plug on an electrical base. As for the document US3521216 , the magnetic means are also able to move electrical contacts of the electrical base so as to provide an electrical connection between the electrical plug and the base.

Pour éviter les risques d'électrocution par contact direct, les pistes électriques du socle et/ou de la fiche électrique sont généralement positionnées à l'intérieur de gorges plus ou moins profondes et plus ou moins étroites. La présence de ces gorges oblige un positionnement axial de la fiche face au socle afin que la mise en contact soit facilement réalisable. Plus les gorges sont étroites et profondes, plus le positionnement axial doit être précis et contraignant. Cette contrainte d'alignement et de positionnement se fait d'autant plus ressentir au moment de l'arrachement de la prise. Pour remédier à ce problème, le document US3521216 décrit un socle électrique où les pistes électriques ne sont pas dans des gorges. Le socle comporte des pistes électriques qui ne sont plus sous tension lorsque la fiche est retirée du socle. Le socle comporte alors des contacts électriques mobiles placés à l'intérieur dudit socle et non accessibles. Lesdits contacts électriques sont destinés pour venir se connecter aux pistes électriques uniquement lorsque le fiche est en contact avec le socle. Le risque d'électrocution est ainsi réduit lorsque la fiche n'est pas connectée au socle.To avoid the risk of electrocution by direct contact, the electric tracks of the base and / or the electrical plug are generally positioned inside more or less deep grooves and more or less narrow. The presence of these grooves requires an axial positioning of the plug facing the base so that the contact is easily achievable. The narrower and deeper the grooves are, the more precise and restrictive axial positioning must be. This alignment and positioning constraint is all the more felt at the moment of tearing of the grip. To remedy this problem, the document US3521216 describes an electrical base where the electric tracks are not in grooves. The base has electrical tracks that are no longer energized when the plug is removed from the base. The base then has movable electrical contacts placed inside said base and not accessible. Said electrical contacts are intended to connect to the electrical tracks only when the plug is in contact with the base. The risk of electrocution is reduced when the plug is not connected to the base.

D'autres solutions telles que décrites dans la demande de brevet W02012032230 , décrivent des moyens obturateurs venant fermer des zones d'accès aux contacts électriques. Les moyens obturateurs comportent notamment des volets pouvant passer d'une position de fermeture à une position d'ouverture sous l'action d'une force de commande générée par des moyens magnétiques. Lesdits moyens magnétiques sont aussi aptes à déplacer des contacts électriques du socle électrique de manière à assurer une liaison électrique entre la fiche électrique et le socle.Other solutions as described in the patent application W02012032230 , describe shutter means coming to close areas of access to the electrical contacts. The shutter means include flaps that can pass from a closed position to an open position under the action of a control force generated by magnetic means. Said magnetic means are also able to move electrical contacts of the electrical base so as to provide an electrical connection between the electrical plug and the base.

Cette dernière solution peut présenter des problèmes liés une distance d'isolation entre le contact électrique placé dans le socle derrière les volets obturateur et l'extérieur du socle. Certaines normes imposent que la distance d'isolation entre l'extérieur du dispositif et les contacts électrique sous tension soit égale à une distance minimale, par exemple 5 mm. Ainsi, par exemple, si les contacts sont en retrait de 5 mm derrière les volets obturateur, il est alors nécessaire qu'ils se déplacent d'autant pour sortir du socle et pour entrer en connexion avec les pistes de la fiche électrique. Le déplacement étant provoqué par une force magnétique, il est parfois difficile d'assurer un tel déplacement sur une telle distance.This last solution may present problems related to an isolation distance between the electrical contact placed in the base behind the shutter flaps and the outside of the base. Some standards require that the isolation distance between the outside of the device and the live electrical contacts be equal to a minimum distance, for example 5 mm. Thus, for example, if the contacts are recessed 5 mm behind the shutter shutters, it is then necessary that they move all the way out of the base and to enter into connection with the tracks of the electrical plug. The displacement being caused by a magnetic force, it is sometimes difficult to ensure such a displacement on such a distance.

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

Selon un mode de réalisation, l'ensemble de prises électriques 1 comporte une fiche 10 et un socle 20 adaptés pour collaborer l'un à l'autre de façon amovible.According to one embodiment, the set of electrical outlets 1 comprises a plug 10 and a base 20 adapted to collaborate with each other removably.

Comme représenté sur la figure 1, ladite fiche électrique 10 comporte un corps 15 comportant au moins une face de contact sensiblement plane. Ledit socle électrique 20 comporte un corps 25 comportant au moins une face de contact sensiblement plane.

Said electrical base 20 comprises a body 25 comprising at least one substantially flat contact face. The contact faces of the base 20 and the plug 10 are intended to be placed in contact with each other when said plug is in contact with said base ( figures 2 and 4 ).

La fiche 10 comporte au moins deux pistes électriques 11, 12 disposées sur la face de contact de ladite fiche. Lesdites pistes électriques sont de préférence annulaires et concentriques. En outre, lesdites pistes sont isolées électriquement les unes des autres.

Said electrical tracks are preferably annular and concentric. In addition, said tracks are electrically insulated from each other. The electric tracks 11, 12 are connected to electrical wires 17 and are intended to collaborate respectively with electrical contacts 21, 22 of the electrical base 20.

Selon un mode particulier de réalisation tel que représenté sur la figure 12, la fiche électrique 10 comporte de préférence un contact électrique 14 destiné à être connecté à une prise de terre. Ce contact électrique de terre 14 est positionné au centre des deux pistes 11, 12 annulaires concentriques.According to a particular embodiment as shown in the figure 12 , the electrical plug 10 preferably comprises an electrical contact 14 to be connected to a ground. This earth electrical contact 14 is positioned at the center of the two concentric annular tracks 11, 12.

Le socle 20 comporte au moins deux contacts électriques 21, 22 destinés à être reliés à des fils électriques non représentés. Les contacts électriques 21, 22 sont solidaires d'un élément magnétique 23 placé à l'intérieur boitier 25 du socle 20. Lesdits au moins deux contacts électriques 21, 22 sont mobiles et peuvent se déplacer entre une position interne dans le socle 20 et une position externe à l'extérieur du socle pour être respectivement en contact électrique direct avec les pistes électriques 11, 12 de la fiche 10 électrique. Selon un mode particulier de réalisation, la face de contact plane du socle 20 comporte des ouvertures 27 à travers lesquelles les contacts électriques 21, 22 peuvent passer.The base 20 comprises at least two electrical contacts 21, 22 intended to be connected to unrepresented electrical wires. The electrical contacts 21, 22 are integral with a magnetic element 23 placed inside the housing 25 of the base 20. Said at least two electrical contacts 21, 22 are movable and can move between an internal position in the base 20 and a external position outside the base to be respectively in direct electrical contact with the electrical tracks 11, 12 of the electrical plug. According to a particular embodiment, the flat contact face of the base 20 has openings 27 through which the electrical contacts 21, 22 can pass.

Selon un mode particulier de réalisation tel que représenté sur la figure 13, le socle électrique 20 comporte de préférence un contact électrique 24 destiné à être connecté à une prise de terre. Ce contact électrique de terre 24 est de préférence positionné au centre de la surface de contact du socle pour venir en contact avec le contact électrique de terre 14 de la fiche électrique 10.According to a particular embodiment as shown in the figure 13 , the electrical base 20 preferably comprises an electrical contact 24 intended to be connected to a ground. This earth electrical contact 24 is preferably positioned in the center of the contact surface of the base to come into contact with the earth contact 14 of the electrical plug 10.

L'ensemble de prises électriques 1 comporte des moyens magnétiques de commande 13, 23 générant une première force de commande F1 pour positionner et maintenir la fiche 10 sur le socle 20 de manière à ce que les pistes annulaires 11, 12 soient respectivement en contact avec les contacts électriques 21, 22 du socle 20.The set of electrical outlets 1 comprises magnetic control means 13, 23 generating a first control force F1 for positioning and holding the plug 10 on the base 20 so that the annular tracks 11, 12 are in contact with each other respectively. the electrical contacts 21, 22 of the base 20.

Les moyens magnétiques de commande 13, 23 comportent un premier aimant 13 intégré dans la fiche 10. En outre, les moyens magnétiques comportent un élément magnétique mobile 23 intégré au socle 20 et solidaire des contacts électriques 21, 22 mobiles. Le premier aimant 13 génère un flux magnétique de commande Φcom créant une première force de commande F1 attirant l'élément magnétique mobile 23 et déplaçant les contacts électriques 21, 22 entre la position interne et la position externe.The magnetic control means 13, 23 comprise a first magnet 13 integrated in the plug 10. In addition, the magnetic means comprise a movable magnetic element 23 integrated in the base 20 and secured to the movable electrical contacts 21, 22. The first magnet 13 generates a control magnetic flux Φ com creating a first control force F1 attracting the movable magnetic element 23 and moving the electrical contacts 21, 22 between the internal position and the external position.

De préférence, ledit premier aimant 13 et ledit élément magnétique 23 sont de forme annulaire. En outre, ils sont disposés respectivement sur la périphérie des faces de contact de la fiche 10 et du socle 20 afin que la première force de commande F1 soit mieux répartie afin d'améliorer la précision et l'efficacité du positionnement et du maintien de la fiche 10 sur le socle 20.Preferably, said first magnet 13 and said magnetic element 23 are annular in shape. In addition, they are respectively disposed on the periphery of the contact faces of the plug 10 and the base 20 so that the first F1 control force is better distributed to improve the accuracy and efficiency of the positioning and maintenance of the sheet 10 on the base 20.

Selon un premier mode particulier de réalisation, ledit au moins un élément magnétique mobile 23 comporte un anneau métallique réalisé dans un matériau magnétisable.According to a first particular embodiment, said at least one movable magnetic element 23 comprises a metal ring made of a magnetizable material.

Selon un second mode particulier de réalisation tel que représenté sur les figures 3 et 4, ledit au moins un élément magnétique mobile 23 comporte une zone aimantée. Avantageusement, selon ce mode de réalisation, ledit élément magnétique 23 comporte un second aimant annulaire 44 destiné à être placé en vis-à-vis du premier aimant annulaire 13 lorsque la fiche 10 est en contact avec le socle 20. Selon ce second mode particulier de réalisation, la première force de commande F1 est augmentée par rapport à celle obtenue dans le premier mode particulier de réalisation.According to a second particular embodiment as shown in the Figures 3 and 4 said at least one movable magnetic element 23 has a magnetic zone. Advantageously, according to this embodiment, said magnetic element 23 comprises a second annular magnet 44 intended to be placed opposite the first annular magnet 13 when the plug 10 is in contact with the base 20. According to this second particular embodiment, the first control force F1 is increased relative to that obtained in the first particular embodiment.

Selon un mode préférentiel de réalisation, les moyens magnétiques de commande 13, 23 comportent une culasse magnétique 33 composée de deux parties 33A, 33B. Une première partie 33A de la culasse 33 est disposée dans la fiche 10 et une seconde partie 33B de la culasse 33 est disposée dans le socle 20.According to a preferred embodiment, the magnetic control means 13, 23 comprise a magnetic yoke 33 composed of two parts 33A, 33B. A first portion 33A of the yoke 33 is disposed in the plug 10 and a second portion 33B of the yoke 33 is disposed in the base 20.

Comme représenté sur les figures 3 et 4, la première partie 33A de la culasse comprend le premier aimant 13. En effet, la première partie 33A comporte un corps ayant une première zone magnétique solidaire du premier aimant 13. A titre d'exemple le corps de la première partie présente une forme sensiblement cylindrique.As shown on Figures 3 and 4 , the first portion 33A of the yoke comprises the first magnet 13. In fact, the first portion 33A comprises a body having a first magnetic zone secured to the first magnet 13. For example, the body of the first portion has a shape substantially cylindrical.

La seconde partie 33B de la culasse disposée dans le socle 20 est reliée à l'élément magnétique mobile 23 par un entrefer axial glissant E2.The second portion 33B of the yoke disposed in the base 20 is connected to the movable magnetic element 23 by a sliding axial air gap E2.

Le flux magnétique de commande Φcom généré par le premier aimant 13 circule à travers les première et seconde parties 33A, 33B de la culasse magnétique, l'élément magnétique mobile 23 et l'entrefer glissant E2.The magnetic control flux Φ com generated by the first magnet 13 flows through the first and second parts 33A, 33B of the magnetic yoke, the movable magnetic element 23 and the sliding air gap E2.

Les premières et seconde parties 33A, 33B de la culasse magnétique comportent chacune au moins une zone magnétique respectivement agencées pour se positionner en vis-à-vis l'une de l'autre lorsque ladite fiche électrique 10 est connectée au socle 20.The first and second portions 33A, 33B of the magnetic yoke each comprise at least one magnetic zone respectively arranged to be positioned facing each other when said electrical plug 10 is connected to the base 20.

Comme représenté sur la figure 4, le corps cylindrique de la première partie 33A comporte une seconde zone magnétique destinée à être positionnée en vis-à-vis d'une seconde zone magnétique de la deuxième partie 33B.As shown on the figure 4 , the cylindrical body of the first portion 33A comprises a second magnetic zone intended to be positioned vis-à-vis a second magnetic zone of the second portion 33B.

Comme représenté sur les figures 3 et 4, la seconde partie 33B comporte un corps ayant une première zone magnétique reliée à l'élément magnétique mobile 23 par l'entrefer axial glissant E2. En outre, comme représenté sur la figure 4, la seconde partie 33B comporte une seconde zone magnétique destinée à être positionnée en vis-à-vis de la seconde zone magnétique de la première partie 33A.As shown on Figures 3 and 4 , the second portion 33B comprises a body having a first magnetic zone connected to the movable magnetic element 23 by the sliding axial air gap E2. In addition, as shown on the figure 4 , the second portion 33B includes a second magnetic zone intended to be positioned vis-à-vis the second magnetic zone of the first portion 33A.

A titre d'exemple, le corps de la seconde partie 33B de la culasse magnétique 33 présente une forme sensiblement cylindrique.By way of example, the body of the second portion 33B of the magnetic yoke 33 has a substantially cylindrical shape.

Le fonctionnement de cet ensemble de prises selon l'invention est le suivant.The operation of this set of sockets according to the invention is as follows.

Comme représenté sur la figure 3, la première force de commande F1 n'a pas d'effet sur le positionnement des contacts électriques 21, 22 car la fiche 10 se trouve éloignée du socle 20. Les contacts électriques 21, 22 placés dans la position interne, sont en retrait par rapport à la surface de contact du socle 20. Les contacts électriques 21, 22 sont maintenus dans cette position à l'intérieur du boitier 25 du socle 20 par des moyens élastiques de commande 28 générant une seconde force de commande F2. Selon un mode de réalisation de l'invention, les moyens élastiques 28 comporte un ressort. La seconde force de commande F2 est d'intensité inférieure et de sens opposé à la première force de commande F1. Ladite seconde force de commande F2 est apte à déplacer les contacts électriques 21, 22 entre la position externe et la position interne.As shown on the figure 3 , the first control force F1 has no effect on the positioning of the electrical contacts 21, 22 because the plug 10 is remote from the base 20. The electrical contacts 21, 22 placed in the internal position, are set back by relative to the contact surface of the base 20. The electrical contacts 21, 22 are held in this position inside the housing 25 of the base 20 by elastic control means 28 generating a second control force F2. According to one embodiment of the invention, the elastic means 28 comprises a spring. The second control force F2 is of lower intensity and of opposite direction to the first control force F1. Said second control force F2 is able to move the electrical contacts 21, 22 between the external position and the internal position.

Lorsque la fiche 10 se rapproche et vient en contact avec le socle 20, l'intensité de la première force de commande F1 devient supérieure à celle de la seconde force de commande F2. Comme représenté sur la figure 4, L'élément magnétique 23 et l'aimant 13 sont attirés l'un à l'autre ce qui provoque un positionnement brusque et un maintien de la fiche 10 sur le socle 20. Ainsi la première force de commande F1 agit sur l'élément magnétique 23 et entraine son déplacement de la position interne vers la position externe. On observe alors un déplacement concomitant des contacts électriques 21, 22 entre la position interne et la position externe. Ladite première force de commande F1 est ainsi apte à déplacer les contacts électriques 21, 22 entre les deux positions. Si la fiche 10 est retirée, alors la première force de commande F1 devient inférieure à la seconde force de commande F2 qui est apte à déplacer les contacts électriques 21, 22 entre la position externe et la position interne.When the plug 10 approaches and comes into contact with the base 20, the intensity of the first control force F1 becomes greater than that of the second control force F2. As shown on the figure 4 , The magnetic element 23 and the magnet 13 are attracted to each other which causes a sudden positioning and holding the plug 10 on the base 20. Thus the first control force F1 acts on the element magnetic 23 and causes its movement from the internal position to the external position. There is then a concomitant movement of the electrical contacts 21, 22 between the internal position and the external position. Said first control force F1 is thus able to move the electrical contacts 21, 22 between the two positions. If the plug 10 is removed, then the first control force F1 becomes smaller than the second control force F2 which is able to move the electrical contacts 21, 22 between the external position and the internal position.

Lorsque la fiche 10 est en contact avec le socle 20, le flux magnétique de commande Φcom généré par le premier aimant 13 circule essentiellement à travers les première et seconde parties dans la culasse magnétique, l'élément magnétique mobile 23 et l'entrefer glissant E2. Contrairement aux solutions existantes, la présence de la culasse magnétique assure le passage du flux de commande de manière plus efficace. L'efficacité de la culasse est maximale lorsque la seconde zone magnétique de la première partie 33A est positionnée en vis-à-vis de la seconde zone magnétique de la deuxième partie.When the plug 10 is in contact with the base 20, the magnetic flux of Φ com command generated by the first magnet 13 substantially flows through the first and second parts in the magnetic yoke, the movable magnetic element 23 and the sliding air gap E2. Unlike existing solutions, the presence of the magnetic yoke ensures the passage of the control flow more efficiently. The efficiency of the yoke is maximum when the second magnetic zone of the first part 33A is positioned vis-à-vis the second magnetic zone of the second part.

L'objectif de la solution telle que décrite est d'obtenir une première force de commande F1 suffisante lorsque la course de l'élément magnétique mobile 23 et des contacts mobiles 21, 22 est supérieure à 4,5 mm, course mesurée entre la position interne et la position externe. La présence de la culasse magnétique 33 dans l'ensemble de prises selon l'invention avec une première partie 33A dans la fiche 10 et et une seconde partie 33B dans le socle 20 permet de canaliser une partie du flux magnétique de commande Φcom vers l'élément magnétique mobile 23 de manière anticipée par rapport à une solution connue. Cela a pour conséquence une augmentation de la première force de commande F1.The objective of the solution as described is to obtain a first F1 sufficient control force when the stroke of the movable magnetic element 23 and movable contacts 21, 22 is greater than 4.5 mm, measured stroke between the position internal and external position. The presence of the magnetic yoke 33 in the set of sockets according to the invention with a first portion 33A in the plug 10 and and a second portion 33B in the base 20 can channel a portion of the control magnetic flux Φ com to the mobile magnetic element 23 in anticipation of a known solution. This results in an increase of the first control force F1.

Comme représenté sur la figure 7, on observe la courbe d'évolution de la première force de commande F1 en trait pointillé pour un ensemble de prise selon l'invention. La courbe en trait plein correspond à la courbe d'évolution de la première force de commande d'un ensemble de prises électriques de type connu. La première force de commande F1 varie entre deux valeurs extrêmes correspondant aux positions interne et externe des contacts électriques 21, 22. A titre d'exemple de réalisation, le dimensionnement de l'ensemble de prises selon l'invention a alors été par exemple fait afin d'obtenir une force de commande équivalente à 52 Newtons lorsque les contacts électrique 21, 22 sont dans la position externe. La première force de commande F1 équivalente mesurée lorsque les contacts électriques 21, 22 sont dans la position interne est alors égale à 9,45 Newtons. A titre de comparaison, pour un ensemble de prises connu (courbe en trait plein) ne comportant pas de culasse magnétique, la force de commande serait seulement de 3,1 Newtons et serait sans doute insuffisante pour entrainer un déplacement de l'ensemble mobile (l'élément magnétique mobile 23 et contacts électriques) présent dans le socle 20. Grace à la solution de l'invention, la première force de commande F1 appliquée lorsque les contacts 21, 22 sont dans la position interne a été multipliée par un facteur 3. L'ensemble de prises électriques selon l'invention est ainsi particulièrement adapté lorsque la distance de fonctionnement entre la position interne et la position externe est importante notamment supérieure à 5 mm. Comme représenté sur la figure 7, l'ensemble de prises selon l'invention permet d'obtenir une force de commande F1 suffisante lorsque les contacts sont dans la position interne tout en ayant une force de commande acceptable lorsque les contacts sont dans une position externe. On entend par acceptable le fait que la force de commande obtenue est équivalente à celle d'un ensemble de prise connu dont la distance de fonctionnent est inférieure à 5 mm.As shown on the figure 7 the evolution curve of the first control force F1 in dotted line is observed for a set of taps according to the invention. The curve in solid line corresponds to the evolution curve of the first control force of a set of electrical outlets of known type. The first control force F1 varies between two extreme values corresponding to the internal and external positions of the electrical contacts 21, 22. As an exemplary embodiment, the sizing of the set of sockets according to the invention was then for example made to obtain a control force equivalent to 52 Newtons when the electrical contacts 21, 22 are in the external position. The first equivalent F1 control force measured when the electrical contacts 21, 22 are in the internal position is then equal to 9.45 Newtons. By way of comparison, for a known set of taps (curve in solid line) not including a magnetic yoke, the control force would be only 3.1 Newtons and would probably be insufficient to cause a displacement of the moving assembly ( the movable magnetic element 23 and electrical contacts) present in the base 20. Thanks to the solution of the invention, the first control force F1 applied when the contacts 21, 22 are in the internal position has been multiplied by a factor 3. The set of electrical sockets according to the invention is thus particularly suitable when the operating distance between the internal position and the external position is important especially greater than 5 mm. As shown on the figure 7 , the set of sockets according to the invention makes it possible to obtain a sufficient F1 control force when the contacts are in the internal position while having an acceptable control force when the contacts are in an external position. Acceptable is the fact that the control force obtained is equivalent to that of a known gripping assembly whose operating distance is less than 5 mm.

Comme représenté sur la figure 8, on observe la courbe d'évolution de la première force de commande F1 en trait pointillé pour un ensemble de prises selon l'invention lorsque la fiche 10 est retirée du socle 20 de façon désaxée. Le point de basculement pour la rétraction de l'élément magnétique mobile 23 et des contacts électriques mobiles 21, 22 intervient lorsque la première force de commande F1 est inférieure à 20 Newtons. Avec un ensemble de prises de type connu (courbe en trait plein) l'angle de basculement entre la fiche et le socle est de 7,5° pour que la rétractation ait lieu. Avec un ensemble de prises selon l'invention (courbe en trait pointillé), l'angle de basculement entre la fiche 10 et le socle 20 est de 5,25°. Plus l'angle de basculement atteint est faible, plus le risque d'électrocution via l'espace libéré par le basculement est réduit.As shown on the figure 8 the evolution curve of the first control force F1 in dashed line is observed for a set of sockets according to the invention when the plug 10 is withdrawn from the base 20 in an off-axis manner. The tilting point for the retraction of the movable magnetic element 23 and the movable electrical contacts 21, 22 occurs when the first control force F1 is less than 20 Newtons. With a set of known type sockets (full line curve) the angle of tilt between the plug and the base is 7.5 ° for the retraction to take place. With a set of sockets according to the invention (curve dashed line), the tilt angle between the plug 10 and the base 20 is 5.25 °. The lower the tilt angle achieved, the lower the risk of electrocution via the space released by the tilt.

Selon un mode de réalisation tel que représenté sur la figure 4bis, la première zone magnétique de la seconde partie 33B de la culasse magnétique 33 comporte de préférence un profil courbe agencé de manière à ce que l'entrefer glissant E2 varie entre au moins deux valeurs maximales d'entrefer.According to an embodiment as shown in the figure 4bis , the first magnetic zone of the second portion 33B of the magnetic yoke 33 preferably comprises a curved profile arranged so that the sliding air gap E2 varies between at least two maximum air gap values.

Lorsque les contacts électriques 21, 22 sont dans la position interne, la seconde partie de la culasse magnétique 33B est séparée de l'élément magnétique 23 par un entrefer glissant E2 atteignant une première valeur maximale. Cette première valeur maximale d'entrefer glissant E2 permet de garantir lorsque la fiche 10 est éloignée du socle 20 que le second aimant 44 associé à l'élément magnétique 23 ne soit pas attiré par la seconde partie 33B de la culasse magnétique 33 et se déplace de manière spontanée. Il est donc nécessaire que la fiche 10 soit en contact avec socle 20 pour que le flux de commande Φcom généré principalement par le premier aimant 13 génère une première force de commande F1 d'intensité suffisante pour assurer le déplacement des contacts électriques 21, 22 de la position interne vers la position externe. A titre d'exemple de réalisation tel que représenté sur les figures 3 et 4bis, l'élément magnétique 23 est en vis-à-vis d'une première zone (a) de la seconde partie 33B de la culasse 33.When the electrical contacts 21, 22 are in the internal position, the second part of the magnetic yoke 33B is separated from the magnetic element 23 by a sliding air gap E2 reaching a first maximum value. This first maximum value of the sliding air gap E2 makes it possible to guarantee when the plug 10 is moved away from the base 20 that the second magnet 44 associated with the magnetic element 23 is not attracted by the second portion 33B of the magnetic yoke 33 and moves spontaneously. It is therefore necessary that the plug 10 is in contact with the base 20 so that the control flow Φ com generated mainly by the first magnet 13 generates a first control force F1 of sufficient intensity to ensure the displacement of the electrical contacts 21, 22 from the internal position to the external position. By way of example of embodiment as represented on the Figures 3 and 4bis the magnetic element 23 is opposite a first zone (a) of the second portion 33B of the yoke 33.

Au cours du déplacement de l'élément magnétique 23, l'entrefer glissant E2 est sensiblement constant et comporte une valeur minimale. A titre d'exemple de réalisation tel que représenté sur les figures 4 et 4bis, l'élément magnétique 23 se déplace en vis-à-vis d'une seconde zone (b) de la seconde partie 33B de la culasse 33.During the displacement of the magnetic element 23, the sliding air gap E2 is substantially constant and has a minimum value. By way of example of embodiment as represented on the Figures 4 and 4bis the magnetic element 23 moves towards a second zone (b) of the second portion 33B of the yoke 33.

Lorsque l'élément magnétique 23 atteint la position externe, la seconde partie 33B de la culasse magnétique 33 est alors séparée de l'élément magnétique 23 par un entrefer glissant E2 atteignant une seconde valeur maximale. Cette seconde valeur maximale d'entrefer glissant E2 permet de garantir que la seconde partie 33B de la culasse magnétique ne retienne ou ne freine le déplacement l'élément magnétique 23. Le flux magnétique de commande Φcom circulant principalement entre le premier aimant 13 et l'élément magnétique 23. Cette modification de la taille de l'entrefer glissant E2 en fin de mouvement permet ainsi d'améliorer la linéarité de la courbe représentative de la première force de commande F1. A titre d'exemple de réalisation tel que représenté sur les figures 4 et 4bis, l'élément magnétique 23 est en vis-à-vis d'une troisième zone (c) de la seconde partie 33B de la culasse 33.When the magnetic element 23 reaches the external position, the second portion 33B of the magnetic yoke 33 is then separated from the magnetic element 23 by a sliding air gap E2 reaching a second maximum value. This second maximum value of sliding air gap E2 makes it possible to guarantee that the second portion 33B of the magnetic yoke does not retain or brake the displacement of the magnetic element 23. The magnetic control flux Φ com circulating mainly between the first magnet 13 and the Magnetic element 23. This modification of the size of the sliding air gap E2 at the end of movement thus makes it possible to improve the linearity of the curve representative of the first control force F1. By way of example of embodiment as represented on the Figures 4 and 4bis the magnetic element 23 is opposite a third zone (c) of the second portion 33B of the yoke 33.

L'autre problématique associé à une ensemble de prises électriques concerne le risque de disfonctionnement des moyens élastiques de commande 28 générant une seconde force de commande F2. En effet, avec un ensemble de prises de type connu, en cas dysfonctionnement des moyens élastiques de commande 28, les contacts électriques 21, 22 peuvent rester en position externe après que le fiche 10 soit retirée du socle 20. Afin d'assurer la sécurité des personnes, la présence de la culasse magnétique 33 permet aussi de fournir un effort négatif dit de « rentrée » des contacts mobiles 21, 22 lorsque la fiche 10 est retirée du socle 20. L'effort négatif de « rentrée » s'additionne à la seconde force de commande lorsque les moyens élastiques de commande 28 sont opérationnels. Comme représenté sur la figure 5, cet effort négatif est lié à la circulation d'un flux magnétique de rentrée Φren circulant préférentiellement entre le second aimant annulaire 44 de l'élément magnétique 23 et la seconde parties 33B dans la culasse magnétique 33 et l'entrefer glissant E2. La culasse magnétique 33 joue donc un double rôle en fonction de la présence ou non de la fiche 10 en contact sur le socle 20.The other problem associated with a set of electrical outlets concerns the risk of malfunction of the elastic control means 28 generating a second control force F2. Indeed, with a set of known type of plugs, in case of malfunction of the elastic control means 28, the electrical contacts 21, 22 can remain in the external position after the plug 10 is removed from the base 20. To ensure safety people, the the presence of the magnetic yoke 33 also makes it possible to provide a negative force called "retraction" of the movable contacts 21, 22 when the plug 10 is removed from the base 20. The negative "return" force is added to the second force of control when the elastic control means 28 are operational. As shown on the figure 5 this negative force is related to the circulation of a magnetic reentry flux Φ ren circulating preferentially between the second annular magnet 44 of the magnetic element 23 and the second part 33B in the magnetic yoke 33 and the sliding air gap E2. The magnetic yoke 33 thus plays a dual role depending on the presence or absence of the plug 10 in contact on the base 20.

Dans le cas où la fiche 10 est en contact avec le socle 20, la culasse magnétique 33 augmente les efforts pour favoriser la sortie des contacts électriques 21, 22 au début du déplacement des éléments mobiles du socle 20 de la position interne vers la position externe.In the case where the plug 10 is in contact with the base 20, the magnetic yoke 33 increases the efforts to promote the output of the electrical contacts 21, 22 at the beginning of the movement of the movable elements of the base 20 from the internal position to the external position .

Dans le cas où la fiche 10 est retirée du socle 20, la culasse 33 permet la création d'un effort négatif dit de « rentrée » aidant le déplacement des contacts électriques 21, 22 de la position externe vers la position interne. Comme représenté sur la figure 9 à titre d'exemple de réalisation, lorsque les contacts électriques 21, 22 sont dans la position externe (déplacement égal à 0 mm), un effort négatif est environ égal à -3,6 Newton. Cet effort reste négatif jusqu'à un déplacement de 7mm, position où les contacts électriques 21, 22 sont obligatoirement à l'intérieur du socle 20. Dans ce cas, et lors d'une défaillance des moyens élastiques de commande 28, l'ensemble de prise selon l'invention assure un retrait des contacts électriques à l'intérieur du socle 20.In the case where the plug 10 is removed from the base 20, the yoke 33 allows the creation of a negative force called "retraction" helping moving the electrical contacts 21, 22 from the outer position to the internal position. As shown on the figure 9 as an exemplary embodiment, when the electrical contacts 21, 22 are in the outer position (displacement equal to 0 mm), a negative force is approximately equal to -3.6 newton. This force remains negative until a displacement of 7mm, position where the electrical contacts 21, 22 are necessarily inside the base 20. In this case, and during a failure of the elastic control means 28, the assembly socket according to the invention ensures a withdrawal of the electrical contacts inside the base 20.

Selon un mode de développement de l'invention, le socle 20 de l'ensemble de prise électrique 1 comporte des moyens obturateurs 26. Lesdits moyens obturateurs sont positionnés devant les ouvertures 27 à travers lesquelles les contacts électriques peuvent passer. En outre, les moyens obturateurs 26 sont aptes à passer d'une position de fermeture à une position d'ouverture sous l'action de la première force de commande F1 pour laisser passer les contacts électriques 21, 22 de la position interne à la position externe. Selon ce mode de réalisation, l'ouverture des moyens obturateurs 26 est de préférence provoquée par une poussée des contacts électriques 21, 22 sur lesdits moyens obturateurs 26. Lorsque les contacts électriques 21, 22 se déplacent sous l'action de la première force de commande F1, ils tendent à écarter les moyens obturateurs 26 pour passer à travers les ouvertures 27.According to one embodiment of the invention, the base 20 of the electrical outlet assembly 1 comprises shutter means 26. Said shutter means are positioned in front of the openings 27 through which the electrical contacts can pass. In addition, the shutter means 26 are able to pass from a closed position to an open position under the action of the first control force F1 to let the electrical contacts 21, 22 from the internal position to the position. external. According to this mode of embodiment, the opening of the shutter means 26 is preferably caused by a thrust of the electrical contacts 21, 22 on said shutter means 26. When the electrical contacts 21, 22 move under the action of the first control force F1, they tend to spread shutter means 26 to pass through openings 27.

Selon un mode particulier de réalisation tel que présenté sur les figures 10 et 11, les moyens obturateurs 26 de chaque ouverture comporte respectivement deux volets obturateurs. Chaque volet obturateur est alors relié à un ressort de fermeture 29. Avantageusement, les moyens obturateurs 26 sont ramenés dans une position de fermeture sous l'action de force engendrées par des ressorts de fermeture 29.According to a particular embodiment as presented on the Figures 10 and 11 , the shutter means 26 of each opening respectively comprises two shutter flaps. Each shutter shutter is then connected to a closing spring 29. Advantageously, the shutter means 26 are returned to a closed position under the action of force generated by closing springs 29.

Selon une variante de réalisation, le socle 20 comporte des ressorts de pression de contact 30. En pratique, chaque contact électrique est relié de manière solidaire à l'élément magnétique 23 par un ressort de pression de contact 30. Lesdits ressorts permettent d'assurer que la pression de contact entre chaque contact électrique 21, 22 et une piste électriques 11, 12 est suffisante pour le passage du courant électrique entre le socle 20 et la fiche 10.According to an alternative embodiment, the base 20 comprises contact pressure springs 30. In practice, each electrical contact is integrally connected to the magnetic element 23 by a contact pressure spring 30. Said springs make it possible to ensure that the contact pressure between each electrical contact 21, 22 and an electric track 11, 12 is sufficient for the passage of electric current between the base 20 and the plug 10.
