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 adaptés pour collaborer l'un à l'autre de façon amovible. Ladite fiche comportant au moins deux pistes électriques annulaires concentriques destinées à venir respectivement collaborer avec des contacts électriques du socle électrique. Des moyens magnétiques de commande génèrent une première force de commande pour positionner et maintenir la fiche sur le socle de manière à ce que les pistes électriques annulaires soient respectivement en contact avec les contacts électriques du socle, la première force de commande étant inversement proportionnelle à la distance séparant la fiches électrique du socle. Le socle comporte des moyens élastiques de commande générant une seconde force de commande de sens opposé à la première force de commande et étant apte à déplacer les contacts électriques entre une seconde position à l'extérieur dudit socle et une première position à l'intérieur du socle, la seconde force de commande étant d'intensité inférieure à l'intensité maximale de la première force de commande.The invention relates to a set of electrical outlets having a plug and a base adapted to collaborate with each other removably.

The base comprises elastic control means generating a second control force in the opposite direction to the first control force and being able to move the electrical contacts between a second position outside said base and a first position inside the base. base, the second control force being of intensity less than the maximum intensity of the first control force.

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 le 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 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.

Cependant les pistes électriques du socle, bien que non connectées électriquement sont apparentes. Ceci peut présenter deux inconvénients. D'une part, il n'est pas préconisé par les normes d'avoir un accès direct à des pistes électriques destinées à être sous tension. D'autre part, en cas de disfonctionnement du mécanisme autorisant le déplacement des contacts électriques mobiles d'une position connectée à une position non connectée, les pistes du socle risquent d'être sous tension bien que la fiche soit retirée.However, the electrical tracks of the base, although not electrically connected are apparent. This can have two disadvantages. On the one hand, it is not recommended by the standards to have direct access to electrical tracks intended to be powered. On the other hand, in the event of malfunction of the mechanism allowing the moving electrical contacts to move from a position connected to an unconnected position, the tracks of the base may be energized even though the plug is removed.

Certaine solution telle que notamment décrite dans la demande de brevet française déposée au nom de la demanderesse et ayant pour titre « Ensemble de prises électriques » présentent des moyens sécurisant l'accès au contact électrique lors du passage d'une position connectée à une position non connectée (figures 1 et 2). Cependant l'efficacité de ce type solution est fortement dépendante de la direction selon laquelle l'arrachement de la fiche est effectué. En effet, comme représenté sur la figure 4A, lorsque la fiche est retirée selon une direction qui n'est pas perpendiculaire au plan de contact entre la fiche et le socle, les moyens sécurisant l'accès aux contacts électriques ne sont pas totalement opérationnels. En effet, la fiche peut partiellement être encore en contact avec le socle sur un point de sa périphérie et être éloignée dudit socle au niveau d'un second point de sa périphérie. Dans cette position, les contacts électriques sous tension (position connectée) sont accessibles par un utilisateur manipulant l'ensemble de prise électrique.Certain solution as described in particular in the French patent application filed in the name of the applicant and entitled "Set of electrical outlets' means providing secure access to the electrical contact when moving from a position connected to an unconnected position ( Figures 1 and 2 ). However the effectiveness of this type of solution is highly dependent on the direction in which the tearing of the plug is performed. Indeed, as represented on the Figure 4A when the plug is removed in a direction that is not perpendicular to the contact plane between the plug and the base, the means securing access to the electrical contacts are not fully operational. Indeed, the plug may partially still be in contact with the base on a point of its periphery and be away from said base at a second point of its periphery. In this position, the live electrical contacts (connected position) are accessible by a user handling the electrical outlet assembly.

Comme cela est représenté sur la figure 5, les courbes d'évolution de la force d'attraction de la fiche sur le socle sont dépendantes à la fois de la distance e entre ladite fiche et ledit socle mais aussi de l'angle d'arrachement de la fiche par rapport au socle. La distance e est sensiblement égale à la distance la plus grande entre un point de la circonférence de la fiche et la surface plane du socle suivant la direction Y.As shown on the figure 5 , the curves of evolution of the force of attraction of the plug on the base are dependent on both the distance e between said plug and said base but also the angle of tear of the plug relative to the base. The distance e is substantially equal to the largest distance between a point of the circumference of the plug and the flat surface of the base in the Y direction.

Une première courbe en trait plein représente l'évolution de la force d'attraction F de la fiche sur le socle en fonction de la distance séparant ladite fiche et ledit socle lorsque la fiche est retirée selon une direction perpendiculaire au plan de contact fiche-socle. La force d'attraction F devient inférieure à une force de commande Fdec rappelant les contacts électriques dans une position déconnectée à partir d'une première distance de séparation e_dec-lin.A first curve in solid line represents the evolution of the force of attraction F of the plug on the base according to the distance separating said plug and said base when the plug is removed in a direction perpendicular to the contact plane plug-base . The attractive force F becomes smaller than a control force Fdec recalling the electrical contacts in a disconnected position from a first separation distance e_dec-lin.

Une seconde courbe en trait pointillés représente l'évolution de ladite force d'attraction F lorsque la fiche est retirée selon une direction qui n'est pas perpendiculaire au plan de contact fiche-socle. La force d'attraction F devient inférieure à la force de commande Fdec à partir d'une seconde distance de séparation e_dec-ang.A second dotted line curve represents the evolution of said attraction force F when the plug is removed in a direction that is not perpendicular to the plug-socket contact plane. The attractive force F becomes smaller than the control force Fdec from a second separation distance e_dec-ang.

Comme cela est représenté sur la figure 5, la seconde distance de séparation e_dec-ang est supérieure à la première distance de séparation e_dec-lin. En outre, cette distance e_dec-ang étant telle qu'un utilisateur peut atteindre de façon malencontreuse les contacts électriques avant que ces derniers ne soient passés en position déconnectée.As shown on the figure 5 the second separation distance e_dec-ang is greater than the first separation distance e_dec-lin. In Moreover, this distance e_dec-ang being such that a user can unintentionally reach the electrical contacts before they have moved to the disconnected position.

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

Selon un mode de réalisation préférentiel de réalisation tel que représenté sur la figures 1 et 2, l'ensemble de prises électriques 1 comportant une fiche 10 et un socle 20 électriques adaptés pour collaborer l'un à l'autre de façon amovible. 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. Les faces de contact du socle 20 et de la fiche 10 sont destinées être placées en contact l'une de l'autre lorsque ladite fiche est assemblée audit socle (figure 2). La fiche et le socle en contact formant un ensemble de prises électriques se développant selon un axe longitudinal Y.According to a preferred embodiment as shown in the Figures 1 and 2 , the set of electrical sockets 1 having an electrical plug 10 and base 20 adapted to collaborate with each other removably. Said electrical plug 10 comprises a body 15 comprising at least one substantially flat contact face. 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 assembled to said base ( figure 2 ). The plug and the base in contact forming a set of electrical outlets developing along a longitudinal axis Y.

La fiche 10 comporte au moins deux pistes électriques 11, 12 disposés sur la face de contact de ladite fiche. Lesdites pistes électriques sont de préférence annulaires et concentriques, lesdites pistes se développant autour de l'axe longitudinal Y. En outre, lesdites pistes sont isolées électriquement les unes des autres.The plug 10 comprises at least two electrical tracks 11, 12 disposed on the contact face of said plug. Said electrical tracks are preferably annular and concentric, said tracks developing around the longitudinal axis Y. In addition, said tracks are electrically insulated from each other.

Les pistes électriques 11, 12 sont reliées à des fils électrique 17 et sont destinées à venir respectivement collaborer avec des contacts électriques 21, 22 du socle électrique 20.The electric tracks 11, 12 are connected to electrical wires 17 and are designed to collaborate respectively with electrical contacts 21, 22 of the electrical base 20.

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.The electrical plug 10 preferably has 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.

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.

Selon un mode de développement, les moyens magnétiques de commande 13, 23 comportent au moins un premier aimant intégré 13 dans la fiche 10 et au moins un élément magnétique mobile 23 intégré dans un boitier 25 du socle 20. Ledit élément magnétique mobile 23 comporte de préférence une zone aimantée ayant de préférence une forme annulaire. Avantageusement, ledit élément magnétique 23 comporte un aimant annulaire 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 une variante de réalisation, ledit au moins un élément magnétique mobile 23 peut comporter un anneau métallique réalisé dans un matériau magnétisable.According to a development mode, the magnetic control means 13, 23 comprise at least a first integrated magnet 13 in the form 10 and at least a movable magnetic element 23 integrated in a housing 25 of the base 20. Said movable magnetic element 23 preferably comprises a magnetized zone preferably having an annular shape. Advantageously, said magnetic element 23 comprises an annular magnet intended to be placed vis-à-vis the first annular magnet 13 when the plug 10 is in contact with the base 20. According to an alternative embodiment, said at least one movable magnetic element 23 may comprise a metal ring made of a magnetizable material.

Lorsque la fiche est placée à coté du socle, 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. Ledit au moins premier aimant 13 et ledit au moins un élément magnétique 23 sont de préférence de forme annulaire. En outre, ils sont disposés respectivement sur la périphérie des faces de contact de la fiche et du socle 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.When the plug is placed next to the base, 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. Said at least first magnet 13 and said at least one magnetic element 23 are preferably annular. In addition, they are respectively disposed on the periphery of the contact faces of the plug and the base so that the first F1 control force is better distributed to improve the accuracy and efficiency of the positioning and maintenance of the plug 10 on the base 20.

Le socle 20 comporte au moins deux contacts électriques 21, 22 destinés à être reliés à des fils électriques. Les contacts électriques 21, 22 sont solidaires de l'élément magnétique 23 placé à l'intérieur boîtier 25 du socle 20. Lesdits au moins deux contacts électriques 21, 22 sont mobiles et peuvent se déplacer concomitamment avec l'élément magnétique 23 entre une première position à l'intérieur du socle 20 (position déconnectée) et une seconde position (position connectée) 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 peuvent passer.The base 20 comprises at least two electrical contacts 21, 22 intended to be connected to electrical wires. The electrical contacts 21, 22 are integral with the 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 concomitantly with the magnetic element 23 between a first position inside the base 20 (disconnected position) and a second position (connected 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 can pass.

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.The electrical base 20 preferably has 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.

Comme représenté sur la figure 1, les contacts électriques 21, 22 placés dans une première position de fonctionnement (position déconnectée), sont en retrait par rapport à la surface de contact du socle. La première force de commande F1 n'a pas d'effet sur le positionnement des contacts électriques car la fiche 10 se trouve éloignée du socle 20. Les contacts électriques 21, 22 sont maintenus dans cette position à l'intérieur du boîtier 25 du socle 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 à l'intensité maximale de la première force de commande, notamment lorsque la fiche est en contact avec le socle. En outre, la seconde force de commande F2 est de sens opposé à la première force de commande F1.As shown on the figure 1 , the electrical contacts 21, 22 placed in a first operating position (disconnected position), are set back relative to the contact surface of the base. The first control force F1 has no effect on the positioning of the electrical contacts because the plug 10 is remote from the base 20. The electrical contacts 21, 22 are held in this position inside the housing 25 of the base 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 intensity less than the maximum intensity of the first control force, especially when the plug is in contact with the base. In addition, the second control force F2 is opposite to the first control force F1.

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. Ainsi, la première force de commande F1 agit directement sur l'élément magnétique 23 et entraîne son déplacement. On observe alors un déplacement des contacts électriques 21, 22 entre la première position (position déconnectée) et la seconde position (position connectée). Ladite première force de commande F1 est ainsi apte à déplacer les contacts électriques 21, 22 entre la première position et la seconde position.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. Thus, the first control force F1 acts directly on the magnetic element 23 and causes its displacement. There is then a displacement of the electrical contacts 21, 22 between the first position (disconnected position) and the second position (connected position). Said first control force F1 is thus able to move the electrical contacts 21, 22 between the first position and the second position.

Si la fiche 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 seconde position et la première position.If the plug 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 second position and the first position.

Selon un mode de réalisation de l'invention, l'ensemble de prises électriques 1 comporte des moyens magnétiques ou mécaniques de déverrouillage anticipé du déplacement des deux contacts électriques 21, 22 mobiles de la seconde position (position connectée) vers la première position (position déconnectée). Lesdits moyens de déverrouillage sont agencés à l'intérieur de l'ensemble de prise électrique pour permettre de réduire le rapport de force entre la première force de commande F1 et la seconde force de commande F2 au moment de la séparation de la fiche 10 du socle 20. Les moyens magnétiques ou mécaniques de déverrouillage anticipé sont particulièrement efficaces lorsque le déplacement de la fiche se fait selon une direction qui n'est pas parallèle à l'axe longitudinal Y de l'ensemble.According to one embodiment of the invention, the set of electrical sockets 1 comprises magnetic or mechanical means for unlocking the movement of the two movable electrical contacts 21, 22 moving from the second position (connected position) to the first position (position disconnected). Said unlocking means are arranged inside the electrical socket assembly to reduce the power ratio between the first control force F1 and the second control force F2 at the time of separation of the plug 10 from the base 20. The magnetic or mechanical means of early unlocking are particularly effective when the movement of the plug is in a direction that is not parallel to the longitudinal axis Y of all.

Selon un premier mode préférentiel de réalisation de l'invention, l'ensemble de prises électriques 1 comporte des moyens magnétiques de déverrouillage anticipé.According to a first preferred embodiment of the invention, the set of electrical outlets 1 comprises magnetic means for early unlocking.

Lesdits moyens magnétiques de déverrouillage anticipé comportent un premier aimant annulaire de répulsion 40 intégré au socle 20 et un second aimant annulaire de répulsion 41 intégré à la fiche 10. Les aimants de répulsion 40, 41 sont agencés de manière à générer une troisième force de commande F3 s'opposant la première force de commande F1.Said early unlocking magnetic means comprise a first annular repulsion magnet 40 integrated in the base 20 and a second annular repulsion magnet 41 integrated in the plug 10. The repulsion magnets 40, 41 are arranged so as to generate a third control force F3 opposing the first control force F1.

Les premier et second aimants annulaires de répulsion 40, 41 sont respectivement intégrés au socle 20 et à la fiche 10. Lorsque la fiche 10 est en contact avec le socle 20, lesdits aimants sont agencés de manière à la fois à être géométriquement en vis-à-vis et à être en opposition magnétique. La troisième force de commande F3 générée par les aimants annulaires de répulsion 40, 41 est d'intensité inférieure à l'intensité maximale de la première force de commande F1. En outre, les aimants annulaires de répulsion 40, 41 sont de diamètre supérieur au diamètre du premier aimant annulaire 13.The first and second annular repelling magnets 40, 41 are respectively integrated in the base 20 and in the plug 10. When the plug 10 is in contact with the base 20, said magnets are arranged so as to be geometrically in alignment with each other. opposite and to be in magnetic opposition. The third control force F3 generated by the annular repelling magnets 40, 41 is of intensity less than the maximum intensity of the first control force F1. In addition, the annular repelling magnets 40, 41 are greater in diameter than the diameter of the first annular magnet 13.

Lesdits aimants sont de préférence respectivement placés sur la périphérie du socle et de la fiche. Ce positionnement en périphérie permet de privilégier lors d'une ouverture angulaire un proximité des aimants de répulsion 40, 41 plutôt que celle de l'aimant 13 et l'élément magnétique 23. Ainsi, un phénomène de répulsion lié au aimant de répulsion 10, 41 est rendu prioritaire par rapport au phénomène d'attraction lié à l'aimant 13 et l'élément magnétique 23.Said magnets are preferably respectively placed on the periphery of the base and the plug. This positioning on the periphery makes it possible to favor, during an angular opening, a proximity of the repelling magnets 40, 41 rather than that of the magnet 13 and the magnetic element 23. Thus, a repulsion phenomenon related to the repulsion magnet 10, 41 is made a priority with respect to the attraction phenomenon related to the magnet 13 and the magnetic element 23.

Le fonctionnement de l'ensemble de prises électrique est le suivant lorsque la fiche 10 est retirée du socle 20.The operation of the set of electrical outlets is as follows when the plug 10 is removed from the base 20.

Comme représenté sur la figure 6A, si la fiche est retirée du socle selon une direction sensiblement parallèle à celle de l'axe longitudinal Y de l'ensemble de prise, la seconde et la troisième force de commande F2, F3 s'opposent à la première force de commande F1. Cette dernière étant inversement proportionnelle à la distance e séparant la fiche 10 du socle 20, devient rapidement d'intensité inférieure à la seconde et troisième forces de commande F2, F3 qui tendent alors à rappeler les contacts électriques 21, 22 de la seconde position (position connectée) à la première position (position déconnectée). La distance e correspond sensiblement à la plus grande entre un point de la circonférence de la fiche 10 et la surface plane du socle 20 suivant la direction Y. La distance dite de séparation est faible de manière à ce qu'un utilisateur ne puisse pas entrer en contact avec les contacts électriques 21, 22 placés encore dans la seconde position (position connectée).As shown on the Figure 6A if the plug is removed from the socket in a direction substantially parallel to that of the longitudinal axis Y of the tap assembly, the second and third control forces F2, F3 are opposed to the first control force F1. The latter being inversely proportional at the distance e separating the plug 10 from the base 20, it rapidly becomes of lower intensity than the second and third control forces F2, F3 which then tend to return the electrical contacts 21, 22 from the second position (connected position) to the first position (disconnected position). The distance e substantially corresponds to the largest between a point of the circumference of the plug 10 and the flat surface of the base 20 in the direction Y. The so-called separation distance is small so that a user can not enter in contact with the electrical contacts 21, 22 placed still in the second position (connected position).

Si la fiche est retirée du socle selon une direction qui n'est pas parallèle à celle de l'axe longitudinal Y de l'ensemble de prise, comme représenté sur la figure 6B, une partie de la fiche 10 reste en contact avec le socle 20 alors qu'une autre partie est séparée du socle par une distance de séparation e. Cependant, comme cela est représenté sur la figure 7, contrairement aux solutions connues (figure 5), les courbes d'évolution de la force d'attraction de la fiche 10 sur le socle 20 ne sont dépendantes que de la distance e entre ladite fiche et ledit socle. La présence d'un angle d'arrachement de la fiche par rapport au socle ne retarde plus le passage des contacts électriques de la seconde position (position connectée) à la première position (position déconnectée).If the plug is removed from the socket in a direction that is not parallel to that of the longitudinal axis Y of the tap assembly, as shown in Figure 6B part of the plug 10 remains in contact with the base 20 while another part is separated from the base by a separation distance e. However, as shown on the figure 7 , unlike known solutions ( figure 5 ), the curves of evolution of the force of attraction of the plug 10 on the base 20 are only dependent on the distance e between said plug and said base. The presence of an angle of tear of the plug relative to the base no longer delays the passage of the electrical contacts from the second position (connected position) to the first position (disconnected position).

Un premier ensemble de deux courbes sur la partie haute de la figure 7 représente l'évolution de la première force de commande F1. Une première courbe en trait plein représente l'évolution de ladite force lorsque le déplacement de la fiche se fait selon une direction parallèle à l'axe longitudinal Y. Une seconde courbe en trait pointillé représente l'évolution de ladite force lorsque le déplacement de la fiche ne se fait pas selon une direction parallèle à l'axe longitudinal Y.A first set of two curves on the upper part of the figure 7 represents the evolution of the first F1 control force. A first curve in full line represents the evolution of said force when the movement of the plug is in a direction parallel to the longitudinal axis Y. A second dashed line represents the evolution of said force when the displacement of the plug is not in a direction parallel to the longitudinal axis Y.

Un second ensemble de deux courbes sur la partie médiane de la figure 7 représente l'évolution de la troisième force de commande F3. Une première courbe en trait plein représente l'évolution de ladite force lorsque le déplacement de la fiche se fait selon une direction parallèle à l'axe longitudinal Y. Une seconde courbe en trait pointillé représente l'évolution de ladite force lorsque le déplacement de la fiche ne se fait pas selon une direction parallèle à l'axe longitudinal Y.A second set of two curves on the middle part of the figure 7 represents the evolution of the third control force F3. A first curve in solid line represents the evolution of said force when the movement of the plug is in a direction parallel to the longitudinal axis Y. A second dashed curve represents the evolution of said force when the movement of the plug does not occur in a direction parallel to the longitudinal axis Y.

La force résultante des première et troisième forces de commande F1, F3 varient en fonction de l'angle d'arrachement. De même, Ladite force résultante varie en fonction de la distance e lors d'un arrachement selon une direction parallèle à l'axe longitudinal Y. Selon ce mode de réalisation de l'invention, cette variation de la force résultante est sensiblement la même dans les deux types d'arrachement (angulaire ou linéaire).The resultant force of the first and third control forces F1, F3 varies depending on the breakout angle. Likewise, Said resultant force varies as a function of the distance e during tearing in a direction parallel to the longitudinal axis Y. According to this embodiment of the invention, this variation of the resultant force is substantially the same in both types of tearing (angular or linear).

Selon un second mode préférentiel de réalisation de l'invention, l'ensemble de prises électriques 1 comporte des moyens mécaniques de déverrouillage anticipé du déplacement des deux contacts électriques 21, 22 mobiles de la seconde position (position connectée) vers la première position (position déconnectée).According to a second preferred embodiment of the invention, the set of electrical sockets 1 comprises mechanical means for unlocking the movement of the two movable electrical contacts 21, 22 moving from the second position (connected position) to the first position (position disconnected).

Les moyens mécaniques de déverrouillage sont placés à l'intérieur du socle 20. Lesdits moyens comportent un coulisseau 50 supportant les contacts électriques 21, 22. Ledit coulisseau est guidé en translation par rapport au socle 20, de préférence selon une direction sensiblement confondue avec celle de l'axe longitudinal Y. Selon un mode particulier, le coulisseau est monté coulissant sur un guide longitudinal 70 solidaire du socle 20. Le coulisseau comporte une ouverture de guidage traversée par le guide longitudinal 70.The mechanical unlocking means are placed inside the base 20. Said means comprise a slider 50 supporting the electrical contacts 21, 22. Said slider is guided in translation relative to the base 20, preferably in a direction substantially coincident with that of the longitudinal axis Y. According to a particular embodiment, the slider is slidably mounted on a longitudinal guide 70 integral with the base 20. The slider comprises a guide opening through which the longitudinal guide 70 passes.

Les moyens mécaniques de déverrouillage comportent en outre un berceau creux 60 supportant l'élément magnétique annulaire 23 des moyens magnétiques de commande. Selon un mode particulier de réalisation, l'élément magnétique annulaire est fixé de préférence sur un bord de l'ouverture du berceau, le bord ayant un profil circulaire. Le berceau 60 comporte un fond 61 dans lequel vient prendre appui une surface d'appui hémisphérique 51 du coulisseau 50. Ledit berceau est placé dans un volume interne creux du socle 20.The mechanical unlocking means further comprise a hollow cradle 60 supporting the annular magnetic element 23 of the magnetic control means. According to a particular embodiment, the annular magnetic element is preferably fixed on an edge of the opening of the cradle, the edge having a circular profile. The cradle 60 comprises a bottom 61 in which is supported a hemispherical bearing surface 51 of the slide 50. Said cradle is placed in a hollow internal volume of the base 20.

Comme représenté sur les figures 12 à 17, le fond 61 du berceau creux 60 comporte de préférence une collerette circulaire 62 faisant saillie par rapport audit fond. La surface d'appui hémisphérique du coulisseau 50 est alors en appui sur ladite collerette. En outre, le fond du berceau creux comporte un trou pour le passage du guide en translation 70 du coulisseau 50. La collerette 62 est alors disposée sur le périmètre du trou 63 placé au fond du berceau 60.As shown on Figures 12 to 17 , the bottom 61 of the hollow cradle 60 preferably comprises a circular collar 62 projecting from said bottom. The hemispherical bearing surface of the slide 50 is then supported on said flange. In addition, the bottom of the hollow cradle has a hole for the passage of the guide in translation 70 of the slider 50. The flange 62 is then disposed on the perimeter of the hole 63 placed at the bottom of the cradle 60.

Le berceau comporte une surface extérieure agencée vis à vis du volume interne du socle 20 de manière à être apte à se déplacer en translation et/ou à pivoter vis-à-vis du socle 20. Le déplacement du berceau permet d'entrainer en translation le coulisseau 50 et les contacts électriques 21, 22 entre la première et la seconde position de fonctionnement.The cradle has an outer surface arranged with respect to the internal volume of the base 20 so as to be able to move in translation and / or to pivot vis-à-vis the base 20. The displacement of the cradle allows to drive in translation the slider 50 and the electrical contacts 21, 22 between the first and the second operating position.

Selon ce mode de réalisation, les moyens élastiques de commande 28 comporte de préférence au moins deux ressorts de rappel disposés de manière symétrique par rapport à l'axe longitudinal Y passant par le centre l'élément magnétique annulaire 23 des moyens magnétiques de commande. Les ressorts exercent respectivement des efforts de traction sur le berceau 60 tendant à placer les contacts électriques 21, 22 dans la première position de fonctionnement (position déconnectée).According to this embodiment, the elastic control means 28 preferably comprises at least two return springs arranged symmetrically with respect to the longitudinal axis Y passing through the center of the annular magnetic element 23 of the magnetic control means. The springs respectively exert tensile forces on the cradle 60 tending to place the electrical contacts 21, 22 in the first operating position (disconnected position).

Comme représenté sur la figure 11A, la seconde force de commande F2 qui est égale à la force résultante des forces F2a, F2b générées respectivement par les ressorts de rappel 28 est d'intensité inférieure à l'intensité maximale de la première force de commande F1. En outre la seconde force de commande F2 est de sens opposé à la première force de commande F1. Selon ce mode de réalisation, les ressorts de rappel sont identiques. Ainsi, les forces de rappel F2a, F2b exercées par lesdits ressorts sont égales d'une part lorsque la fiche 10 est en contact avec le socle 20 ou d'autre part lorsque la fiche 10 est éloignée du socle 20 de manière à ce que la première force de commande F1 ne s'applique pas entre le socle 20 et la fiche 10.As shown on the figure 11A the second control force F2 which is equal to the resultant force of the forces F2a, F2b generated respectively by the return springs 28 is of intensity less than the maximum intensity of the first control force F1. In addition, the second control force F2 has a direction opposite to the first control force F1. According to this embodiment, the return springs are identical. Thus, the restoring forces F2a, F2b exerted by said springs are equal on the one hand when the plug 10 is in contact with the base 20 or on the other hand when the plug 10 is away from the base 20 so that the first control force F1 does not apply between the base 20 and the plug 10.

Lors d'un arrachement de la fiche 10 suivant une direction non parallèle à l'axe longitudinal Y, le fonctionnement de l'ensemble de prises électrique est le suivant : Tel que représenté sur la figure 11B, une partie de la fiche 10 reste en contact avec le socle 20 au point P alors qu'une autre partie est séparée du socle par une distance de séparation e. Tel que représenté sur la figure 11B, ce déséquilibre géométrique de la fiche par rapport à l'axe longitudinal Y entraîne aussi un changement d'orientation de la première force de commande F1 qui n'est plus alignée avec ledit axe. Le premier aimant 13 et l'élément magnétique 23 ne sont plus en vis-à-vis sur toute leur surface. Dans cette configuration la première force de commande F1 s'exprime sous la forme d'un couple C1 au point P. La seconde force de commande F2 reste inchangée mais s'exprime sous la forme d'un couple C2 de sens opposé à C1 au point P.When tearing of the plug 10 in a direction not parallel to the longitudinal axis Y, the operation of the set of electrical outlets is as follows: As shown in FIG. Figure 11B a part of the plug 10 remains in contact with the base 20 at the point P while another part is separated from the base by a separation distance e. As shown on the Figure 11B this geometrical imbalance of the plug with respect to the longitudinal axis Y also causes a change of orientation of the first control force F1, which is no longer aligned with said axis. The first magnet 13 and the magnetic element 23 are no longer vis-à-vis over their entire surface. In this configuration, the first control force F1 is expressed in the form of a pair C1 at point P. The second control force F2 remains unchanged but is expressed in the form of a pair C2 of direction opposite to C1 at point P.

La courbe en trait pointillé sur la partie haute de la figure 10 représente l'évolution du couple C1 lors d'un arrachement angulaire. Le couple C1 diminue avec l'augmentation de la distance de séparation e. Le couple C2 reste lui constant. Lorsque cette distance atteint une valeur e_dec_ang le couple C1 n'est plus suffisant pour compenser l'action du couple C2. Tel que représenté sur la figure 13, ce déséquilibre des couples provoque le pivotement du berceau 60 à l'intérieur du socle 20. Comme représenté sur la figure 11C, les forces F2a et F2b des ressorts de rappel 28 changent à la fois d'orientation et d'intensité, ce qui a pour effet de maintenir le berceau 60 dans cette position pivotée. Ce pivotement du berceau entraîne de manière concomitante un déplacement de la surface de contact hémisphérique 51 du coulisseau 50 sur le fond 61 dudit berceau et un déplacement dudit coulisseau en translation.The dotted line curve on the upper part of the figure 10 represents the evolution of the torque C1 during an angular tearing. C1 torque decreases with increasing separation distance e. The C2 pair remains constant. When this distance reaches a value e_dec_ang the torque C1 is no longer sufficient to compensate for the action of the pair C2. As shown on the figure 13 , this imbalance of the couples causes the cradle 60 to pivot inside the base 20. As shown in FIG. figure 11C , the forces F2a and F2b of the return springs 28 change both orientation and intensity, which has the effect of maintaining the cradle 60 in this rotated position. This pivoting of the cradle concomitantly causes a displacement of the hemispherical contact surface 51 of the slider 50 on the bottom 61 of said cradle and a displacement of said slider in translation.

La courbe en trait plein sur la partie basse de la figure 10 représente quand à elle l'évolution de la première force de commande F1 lors d'un arrachement suivant l'axe longitudinal. Le passage de la seconde position (position connectée) à la première position (position déconnectée) s'effectue pour une distance e_dec_lin. Le positionnement des ressorts de rappel 28 fait que la distance e_dec_ang est notablement inférieure à e_dec_lin. Ainsi, le déplacement des contacts électriques 21, 22 de la seconde position (position connectée) à la première position (position déconnectée) n'est pas retardé par le fait que la fiche 10 est arrachée selon une direction qui n'est parallèle pas à l'axe longitudinal Y.The curve in solid lines on the lower part of the figure 10 when it represents the evolution of the first control force F1 during tearing along the longitudinal axis. The transition from the second position (connected position) to the first position (disconnected position) takes place for a distance e_dec_lin. The positioning of the return springs 28 makes the distance e_dec_ang significantly less than e_dec_lin. Thus, the displacement of the electrical contacts 21, 22 from the second position (connected position) to the first position (disconnected position) is not delayed by the fact that the plug 10 is torn off in a direction which is not parallel to the longitudinal axis Y.

Selon ce second mode de réalisation, le socle 20 comporte des moyens de pression 80 générant une force de pression maintenant un contact mécanique entre la surface d'appui hémisphérique du coulisseau 50 et le fond du berceau.According to this second embodiment, the base 20 comprises pressure means 80 generating a pressing force maintaining a mechanical contact between the hemispherical bearing surface of the slider 50 and the bottom of the cradle.

Selon une variante de réalisation des modes de développement de l'invention tel que représentée sur les figures 17 et 18, 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 pour laisser passer les contacts électriques 21, 22 de la première à la seconde position. 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 de le première à la seconde position sous l'action de la première force de commande, ils tendent à écarter les moyens obturateurs 26 pour passer à travers les ouvertures 27. Avantageusement, les moyens obturateurs 26 sont ramenés dans une position de fermeture sous l'action de force engendrées par des ressorts de fermeture 29. En outre, les moyens obturateurs 26 de chaque ouverture comporte respectivement deux volets obturateurs. Chaque volet obturateur est alors relié à un ressort de fermeture 29.According to an alternative embodiment of the development modes of the invention as represented on the Figures 17 and 18 , the base 20 of the socket 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 to let the electrical contacts 21, 22 from the first to the second position. According to this 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 from the first to the second position under the action of the first control force, they tend to spread the shutter means 26 to pass through the openings 27. Advantageously, the shutter means 26 are brought into a closed position under the action of force generated by closing springs 29. In addition, the shutter means 26 of each opening respectively comprises two shutter flaps. Each shutter shutter is then connected to a closing spring 29.

Selon une autre 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 another 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 allow 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.
