Abstract

The socket has a contact (1) provided with conductive strips (11, 12), and another contact (2) provided with conductor strips (21, 22). The strips occupy a reception position in which the strips form a space between them for inserting and withdrawing pins (5, 6), and an operational position in which the strips form another space to surround the pins. The difference between the spaces formed by the strips is large for the contact (1) than the contact (2). The strips of the contact (2) guide the pin (6) when the pin (6) is relatively moved with respect to the contact (2).

Description

L'invention concerne, de façon générale, la sécurité d'utilisation des appareillages électriques.The invention relates, in general, the safety of use of electrical equipment.

Plus précisément, l'invention concerne une prise électrique comprenant des premier et deuxième contacts dont le premier est doté d'un premier écarteur mobile, ces contacts étant conçus pour recevoir respectivement des première et deuxième broches correspondantes mécaniquement solidaires l'une de l'autre, chaque contact comprenant deux lames conductrices conformées en pince et propres à adopter l'une par rapport à l'autre une position d'accueil permettant un mouvement relatif d'insertion ou de retrait de la broche, et dans laquelle ces lames présentent entre elles un premier espacement, et une position opérationnelle dans laquelle ces lames enserrent la broche correspondante insérée entre elles et présentent entre elles un deuxième espacement.More specifically, the invention relates to an electrical outlet comprising first and second contacts, the first of which is provided with a first movable spacer, these contacts being designed to respectively receive first and second corresponding pins mechanically secured to one another each contact comprising two conductive blades shaped as clamps and adapted to adopt relative to each other a home position allowing a relative movement of insertion or withdrawal of the spindle, and wherein these blades have between them a first spacing, and an operative position in which these blades enclose the corresponding pin inserted between them and have between them a second spacing.

Une prise de ce type est par exemple décrite dans la demande de brevet EP 1 843 434 .A plug of this type is for example described in the patent application EP 1 843 434 .

Une telle prise, qui est dotée d'une fonctionnalité dite de "force d'insertion nulle ou réduite", est conçue pour n'opposer, par rapport à une prise ordinaire, qu'une force moindre à l'insertion et à l'extraction volontaire d'une fiche, mais pour opposer une force au moins aussi importante à toute extraction intempestive de la fiche.Such a plug, which has a so-called "zero or reduced insertion force" feature, is designed to oppose, with respect to an ordinary grip, only a lower force at insertion and insertion. voluntary extraction of a plug, but to oppose a force at least as important to any untimely extraction of the plug.

Cette fonctionnalité est généralement prévue sur des prises relativement sophistiquées et / ou sur des prises adaptées à des applications particulières, c'est-à-dire sur des prises susceptibles de requérir un niveau de sécurité accru.This feature is usually provided on relatively sophisticated sockets and / or sockets adapted to particular applications, that is to say on sockets likely to require an increased level of security.

Dans ce contexte, l'invention vise précisément à proposer une prise à force d'insertion nulle ou réduite et dans laquelle le risque de circulation d'un courant électrique entre les première et deuxième broches avant introduction complète de ces broches dans la prise est réduit ou supprimé.In this context, the invention aims precisely to propose a null or reduced insertion force and in which the risk of circulation of an electric current between the first and second pins before Full introduction of these pins into the socket is reduced or removed.

A cette fin, la prise de l'invention, par ailleurs conforme à la définition générique qu'en donne le préambule ci-dessus, est essentiellement caractérisée en ce que la différence entre les premier et deuxième espacements est plus importante pour le premier contact que pour le deuxième contact, les lames du deuxième contact opérant un guidage de la deuxième broche lors de son mouvement relatif par rapport à ce deuxième contact.To this end, the taking of the invention, moreover in conformity with the generic definition given in the preamble above, is essentially characterized in that the difference between the first and second spacings is greater for the first contact than for the first contact. for the second contact, the blades of the second contact operating a guide of the second pin during its relative movement with respect to this second contact.

De préférence, le deuxième contact est doté d'un deuxième écarteur mobile, cinématiquement solidaire du premier écarteur mobile.Preferably, the second contact is provided with a second movable spacer, kinematically secured to the first movable spacer.

Dans ce cas, le premier espacement est avantageusement supérieur au deuxième espacement pour chacun des premier et deuxième contacts.In this case, the first spacing is advantageously greater than the second spacing for each of the first and second contacts.

L'invention peut par exemple être réalisée en prévoyant que les premier et deuxième écarteurs présentent des extrémités actives respectives conformées en coins et conçues pour s'insérer entre les lames des premier et deuxième contacts respectifs, l'extrémité active du deuxième écarteur étant plus pointue que celle du premier écarteur.The invention may for example be achieved by providing that the first and second spacers have respective active ends shaped as wedges and adapted to fit between the blades of the respective first and second contacts, the active end of the second spacer being more pointed than that of the first retractor.

D'autres caractéristiques et avantages de l'invention ressortiront clairement de la description qui en est faite ci-après, à titre indicatif et nullement limitatif, en référence aux dessins annexés, dans lesquels :

  • la figure 1 est une vue en perspective d'un contact à force d'insertion réduite, représenté en position d'accueil et dans lequel une broche est insérée de travers;
  • la figure 2 est une vue de dessus d'une prise connue, comprenant deux contacts tels que celui qu'illustre la figure 1; et
  • la figure 3 est une vue de dessus d'une prise conforme à l'invention.
Other characteristics and advantages of the invention will emerge clearly from the description which is given hereinafter, by way of indication and in no way limitative, with reference to the appended drawings, in which:
  • the figure 1 is a perspective view of a reduced insertion force contact shown in the home position and in which a pin is inserted crookedly;
  • the figure 2 is a top view of a known socket, comprising two contacts such as that illustrated in FIG. figure 1 ; and
  • the figure 3 is a top view of a socket according to the invention.

Comme annoncé précédemment, l'invention concerne une prise électrique comprenant des premier et deuxième contacts 1 et 2, dont le premier au moins est doté d'un écarteur mobile 3.As previously announced, the invention relates to an electrical outlet comprising first and second contacts 1 and 2, at least the first of which is provided with a movable spacer 3.

Par souci de simplicité, la description qui suit prévoit que le deuxième contact 2 est lui-même doté d'un deuxième écarteur 4, cette caractéristique étant toutefois optionnelle pour la mise en oeuvre de l'invention.For the sake of simplicity, the following description provides that the second contact 2 is itself provided with a second spacer 4, this characteristic being however optional for the implementation of the invention.

Les contacts 1 et 2 sont conçus pour recevoir des broches respectives correspondantes 5 et 6, qui appartiennent à une même fiche insérée dans la prise, et qui sont donc mécaniquement solidaires l'une de l'autre.The contacts 1 and 2 are designed to receive corresponding respective pins 5 and 6, which belong to the same plug inserted in the socket, and which are therefore mechanically secured to one another.

Comme le montre la figure 3, chacun de ces contacts 1 et 2 comprend deux lames conductrices telles que 11 et 12 pour le contact 1, et 21, 22 pour le contact 2, ces lames prenant ensemble la forme d'une pince élastique comme illustré à la figure 1.As shown in figure 3 each of these contacts 1 and 2 comprises two conductive blades such as 11 and 12 for the contact 1, and 21, 22 for the contact 2, these blades taking together the form of an elastic clip as illustrated in FIG. figure 1 .

Les lames conductrices de chaque contact peuvent adopter l'une par rapport à l'autre une position d'accueil ou une position opérationnelle.The conductive blades of each contact can adopt relative to each other a home position or an operational position.

La position d'accueil, qui est définie pour le premier contact 1 par introduction de l'extrémité active 30 de l'écarteur 3 entre les lames 11 et 12, permet un libre mouvement relatif d'insertion ou de retrait de la broche 5 dans ce contact 1.The home position, which is defined for the first contact 1 by introduction of the active end 30 of the spacer 3 between the blades 11 and 12, allows a free relative movement of insertion or withdrawal of the pin 5 in this contact 1.

Dans le mode de réalisation illustré, la position d'accueil pour le deuxième contact 2 est définie par introduction de l'extrémité active 40 de l'écarteur 4 entre les lames 21 et 22 et permet un libre mouvement relatif d'insertion ou de retrait de la broche 6 dans ce contact 2.In the illustrated embodiment, the home position for the second contact 2 is defined by introducing the active end 40 of the spacer 4 between the blades 21 and 22 and allows a free relative movement of insertion or withdrawal of pin 6 in this contact 2.

Dans un mode de réalisation moins performant, la position d'accueil pour le deuxième contact 2 est définie de la même façon que dans une prise standard, c'est-à-dire sans l'aide de l'écarteur 4.In a less efficient embodiment, the home position for the second contact 2 is defined in the same way as in a standard socket, that is to say without the aid of the spacer 4.

Dans la position opérationnelle, les lames de chaque contact, à savoir les lames 11 et 12 du contact 1 et les lames 21 et 22 du contact 2, enserrent la broche correspondante qui a été insérée entre ces lames.In the operational position, the blades of each contact, namely the blades 11 and 12 of the contact 1 and the blades 21 and 22 of the contact 2, enclose the corresponding pin which has been inserted between these blades.

Plus précisément, les lames 11 et 12 enserrent alors la broche 5 et les lames 21 et 22 la broche 6, le contact galvanique étant ainsi établi entre le contact 1 et la broche 5 d'une part, et entre le contact 2 et la broche 6 d'autre part.More specifically, the blades 11 and 12 then clamp the pin 5 and the blades 21 and 22 the pin 6, the galvanic contact being established between the contact 1 and the pin 5 on the one hand, and between the contact 2 and the pin 6 on the other hand.

Dans leur position d'accueil, les lames de chaque contact sont écartées l'une de l'autre par un premier espacement, alors qu'elles sont écartées l'une de l'autre par un deuxième espacement dans leur position opérationnelle.In their home position, the blades of each contact are spaced from one another by a first spacing, while they are spaced from each other by a second spacing in their operative position.

Comme le montre la figure 1, l'espacement entre les lames d'un contact n'est pas un paramètre suffisant pour assurer l'absence de contact galvanique entre une broche insérée dans ce contact d'une part, et les lames de ce contact d'autre part, la direction d'introduction de la broche constituant en effet un autre paramètre d'influence.As shown in figure 1 , the spacing between the blades of a contact is not a sufficient parameter to ensure the absence of galvanic contact between a pin inserted in this contact on the one hand, and the blades of this contact on the other hand, the direction of introduction of the spindle constituting indeed another influence parameter.

Ainsi, dans le cas illustré à la figure 2 où les deux broches 5 et 6 sont insérées de travers dans les contacts 1 et 2 correspondants, chacune de ces broches peut venir en contact galvanique avec l'une des lames de ce contact ou les deux, de sorte qu'un courant électrique peut circuler dans l'appareil relié aux broches 5 et 6 avant l'insertion complète de ces dernières dans la prise.Thus, in the case illustrated in figure 2 where the two pins 5 and 6 are inserted transversely in the corresponding contacts 1 and 2, each of these pins can come into galvanic contact with one of the blades of this contact or both, so that an electric current can flow. in the device connected to pins 5 and 6 before the complete insertion of the latter into the socket.

Pour éviter ce phénomène indésirable, l'invention prévoit que la différence entre le premier espacement et le deuxième soit plus importante pour le premier contact 1 que pour le deuxième contact 2.To avoid this undesirable phenomenon, the invention provides that the difference between the first spacing and the second is greater for the first contact 1 than for the second contact 2.

Ainsi, comme le montre la figure 3 qui représente l'état d'une prise conforme à l'invention pendant l'insertion des broches 5 et 6 dans les contacts 1 et 2 respectifs (ou lors de leur retrait hors de ces contacts), la broche 5 est beaucoup plus écartée des lames 11 et 12 que la broche 6 est écartée des lames 21 et 22.So, as shown in figure 3 which represents the state of a plug according to the invention during the insertion of the pins 5 and 6 into the respective contacts 1 and 2 (or when removed from these contacts), the pin 5 is much further apart from blades 11 and 12 that the pin 6 is spaced from the blades 21 and 22.

Dans ces conditions, les lames 21 et 22 du contact 2 opèrent un guidage de la broche 6 lors de son mouvement relatif par rapport à ce contact 2, empêchant ainsi que la broche 6, et la broche 5 qui lui est mécaniquement liée, soient introduites ou retirées de travers dans les contacts 1 et 2, et empêchant donc tout contact galvanique indésirable entre le broche 5 et l'une quelconque des lames 11 et 12.Under these conditions, the blades 21 and 22 of the contact 2 operate a guide pin 6 during its relative movement with respect to the contact 2, thereby preventing the pin 6, and the pin 5 which is mechanically linked thereto, are introduced or removed in the contacts 1 and 2, and thus preventing any undesirable galvanic contact between the pin 5 and any of the blades 11 and 12.

Dans le mode de réalisation illustré, qui constitue le mode de réalisation préféré, le premier espacement est supérieur au deuxième espacement pour chacun des contacts 1 et 2, et le deuxième contact 2 est doté d'un écarteur mobile 4, cinématiquement solidaire de l'écarteur mobile 3 associé au contact 1.In the illustrated embodiment, which is the preferred embodiment, the first spacing is greater than the second spacing for each of the contacts 1 and 2, and the second contact 2 is provided with a movable spacer 4, kinematically integral with the mobile spacer 3 associated with contact 1.

Dans ces conditions, une solution permettant d'assurer que la différence entre le premier espacement et le deuxième soit plus importante pour le premier contact 1 que pour le deuxième contact 2 peut consister, comme le montre la figure 3, à prévoir que l'extrémité active 40 du deuxième écarteur 4 soit plus pointue que l'extrémité active 30 du premier écarteur 3.Under these conditions, a solution making it possible to ensure that the difference between the first spacing and the second is greater for the first contact 1 than for the second contact 2 may consist, as shown in FIG. figure 3 , to provide that the active end 40 of the second spacer 4 is sharper than the active end 30 of the first spacer 3.
