Abstract

The outlet comprises sockets which are maintained in an isolated state as long a connecting plug of application equipment is not completely inserted into the outlet. For this purpose switches (6,7), actuated by the conical surface of a sliding part (18) which is itself actuated by the base (39) of the plug (30) after the contacts (31 and 32) have been completely inserted in the sockets (28 and 29), provide the energisation of the sockets (28 and 29). Thus any arcing between contacts and sockets is prevented. The switches (6 and 7) may also be arc-proof devices. <IMAGE>

Description

L'invention se rapporte à une prise électrique de sécurité dont la mise sous tension des plots conducteurs de la prise est retardée jusqu'à l'introduction complète d'une fiche de raccordement.The invention relates to an electrical safety socket whose powering up of the conductive pads of the socket is delayed until the complete introduction of a connection plug.

Le problème de la protection des plots d'une prise à douilles ou fiches a reçu diverses solutions mais aucune d'elles n'offre une sécurité parfaite lorsque l'on désire conserver la simplicité d'emploi des prises et fiches usuelles c'est-à-dire lorsque la simple introduction d'une fiche de raccordement dans la prise permet la mise sous tension des appareils raccordés à la fiche.The problem of protecting the studs of a socket or plug has received various solutions but none of them offers perfect security when one wishes to keep the simplicity of use of the usual plugs and plugs. i.e. when the simple insertion of a connection plug into the socket enables the devices connected to the plug to be powered up.

Ainsi l'objet de l'invention est une prise recevant les fiches de raccordement ordinaires,les plots de la prise étant normalement non connectés à la source de tension et mis automatiquement sous tension lors de l'introduction simple et complète de la fiche de raccordement dans la prise.Thus the object of the invention is a socket receiving ordinary connection plugs, the plugs of the socket being normally not connected to the voltage source and automatically switched on during the simple and complete introduction of the connection plug. in the socket.

Il en résulte que tous les risques d'accidents susceptibles de se produire par introduction fortuite d'éléments conducteurs autres que les broches d'une fiche de raccordement dans les douilles d'une prise conforme à l'invention sont éliminés, la simple jonction électrique accidentelle des douilles n'entraînant aucune mise sous tension des plots de la prise.It follows that all the risks of accidents likely to occur by accidental introduction of conductive elements other than the pins of a connection plug into the sockets of a socket according to the invention are eliminated, the simple electrical junction accidental sockets resulting in no tensioning of the socket studs.

Un autre objet de l'invention est une prise de ce genre dont la mise sous tension des plots ne s'établit, après introduction de la fiche de raccordement que lorsque celle-ci est conforme à des normes bien définies. Une de ces normes peut être notamment la présence sur la fiche d'une douille normalement reliée à la terre de l'appareil auquel la fiche est connectée.Another object of the invention is a socket of this kind, the tensioning of the studs being established, after introduction of the connection plug only when the latter conforms to well-defined standards. One of these standards may notably be the presence on the plug of a socket normally connected to the ground of the device to which the plug is connected.

Ainsi l'introduction d'une fiche conventionnelle dans la prise ne peut entraîner la mise sous tension des plots de la prise si cette fiche n'est pas conforme à la norme retenue.Thus the introduction of a conventional plug into the socket cannot cause the studs of the socket to be energized if this plug does not comply with the standard adopted.

Si l'on suppose par exemple que l'on veuille utiliser une fiche sur la prise selon l'invention, cette prise étant équipée d'une broche de prise de terre, et que la fiche ne comporte pas de douille correspondante de sorte que la iiche ne peut être introduite dans les douilles de la prise, l'utilisateur ne peut obtenir aucune tension même en raccordant électriquement par un artifice quelconque les douilles de la fiche aux broches de sa prise.If we suppose for example that we want to use a plug on the socket according to the invention, this socket being fitted with a grounding pin, and that the plug does not have a corresponding socket so that the If the plug cannot be inserted into the socket sockets, the user cannot obtain any voltage even by electrically connecting the socket sockets with any device. plug to the pins of its socket.

Un autre objet de l'invention est une prise de ce genre dont le moyen de commande de la mise sous tension des douilles de la prise est un moyen répondant aux normes adoptées ne commandant la mise sous tension qu'après introduction complète des broches de la fiche de raccordement dans les douilles.Another object of the invention is a socket of this kind in which the means for controlling the tensioning of the socket sockets is a means which meets the standards adopted, controlling the tensioning only after complete insertion of the pins of the connection plug in sockets.

Il en résulte que l'on supprime tout risque d'étincelle entre fiches et douilles et qu'en outre la commutation électrique,commandée automatiquement après l'enfoncement total des fiches,peut s'accomplir par tout dispositif anti-étincelle de sécurité incorporé à la prise.As a result, any risk of sparking between plugs and sockets is eliminated and, in addition, the electrical switching, automatically controlled after the plugs are fully inserted, can be accomplished by any safety anti-spark device incorporated in the catch.

Un autre objet de l'invention est d'éviter, après mise sous tension des plots de la fiche tout risque d'étincelle par suite d'un contact défectueux entre fiche et douille par la présence de tout dispositif incorporé à la prise assurant un contact franc entre douille et broche notamment au moyen d'un contact à bille.Another object of the invention is to avoid, after switching on the plugs of the plug, any risk of sparking as a result of a faulty contact between plug and socket by the presence of any device incorporated in the socket ensuring contact straightforward between socket and pin, in particular by means of a ball contact.

Un autre objet de l'invention est une prise de ce type selon laquelle le contact électrique entre fiche de raccordement et douille de la prise n'est établi qu'après une course déterminée des broches dans le logement.des douilles, ce contact étant suivi du déclenchement de la mise sous tension des plots de la prise que par l'introduction complète de la fiche de raccordement dans la prise.Another object of the invention is a socket of this type according to which the electrical contact between the plug and socket of the socket is established only after a determined stroke of the pins in the housing of the sockets, this contact being followed the triggering of the tensioning of the plugs of the socket only by the complete insertion of the connection plug into the socket.

Ainsi toute commande intempestive de la prise en vue de déclencher la mise sous tension des plots de la prise et leur raccordement à un appareil d'utilisation est pratiquement vouée à l'échec les plots ainsi que leur dispositif de commande étant difficilement accessibles.Thus any untimely command of the plug in order to trigger the powering up of the plugs of the plug and their connection to a device for use is practically doomed to failure, the pads as well as their control device being difficult to access.

D'autres avantages et caractéristiques de l'invention apparaîtront au cours de la description suivante faite en référence aux dessins annexés qui représentent à titre d'exemple non limitatif un mode de réalisation d'une fiche de sécurité selon l'invention.Other advantages and characteristics of the invention will become apparent during the following description made with reference to the appended drawings which represent by way of nonlimiting example an embodiment of a safety sheet according to the invention.

In the drawings:
  • FIG. 1 represents the schematic rear view and in elevation of a wall outlet,
  • FIG. 2 represents the schematic view of the section along the line II-II of FIG. 1 before introduction of a connection plug,
  • FIG. 3 represents the same section after insertion of the connection plug and,
  • Figure 4 a side view of a socket of the socket.

La prise murale désignée par la référence générale 1 figure 1 comprend essentiellement des plots tels que 2 et 3 reliés électriquement aux fils de tension 4 et 5 par l'intermédiaire des dispositifs de commutation 6 et 7.The wall outlet designated by the general reference 1 in FIG. 1 essentially comprises studs such as 2 and 3 electrically connected to the tension wires 4 and 5 via the switching devices 6 and 7.

Ces dispositif pouvant être quelconques et par conséquent disponibles dans le commerce n'ont donc été représentés que par leur enveloppe extérieure, leurs bornes d'entrée 8 et 9 et leurs bornes de sortie 10 et 11. Ces dernières sont connectées respectivement aux plots 2 et 3.These devices may be any and therefore commercially available have therefore been shown only by their outer casing, their input terminals 8 and 9 and their output terminals 10 and 11. The latter are connected respectively to the pads 2 and 3.

Ces dispositifs de commutation sont de préférence des dispositifs de sécurité sans production d'étincelle et sont fixés dans l'exemple de réalisation représenté par les vis 12 et 13. Ces dispositifs peuvent être logés éventuellement à l'intérieur de compartiments formés par les parois 14 prévus sur le socle 15 de la prise.These switching devices are preferably safety devices without producing a spark and are fixed in the embodiment shown by the screws 12 and 13. These devices can optionally be housed inside compartments formed by the walls 14 provided on the base 15 of the socket.

La commande des commutateurs 6 et 7 s'effectue au moyen de leurs ergots de commande 16 et 17 pouvant se présenter sous toute forme appropriée à leur organe de commande commun consistant en une pièce coulissante 18 comprenant un passage axial pour le passage de la broche de terre 20.Cette pièce, plus visible figures 2 et 3, coulisse dans un logement cylindrique 19 de la partie médiane de la prise. Elle glisse axialement autour de la broche de prise de terre 20 entre la position qu'elle occupe figure 2 lorsqu'elle est seulement sollicitée par le ressort 21 et la position qu'elle occupe figure 3 lorsque la fiche de raccordement 30 est enfoncée.The switches 6 and 7 are controlled by means of their control lugs 16 and 17 which may be in any form suitable for their common control member consisting of a sliding part 18 comprising an axial passage for the passage of the spindle. earth 20.This part, more visible in Figures 2 and 3, slides in a cylindrical housing 19 in the middle part of the socket. It slides axially around the earth pin 20 between the position it occupies in FIG. 2 when it is only stressed by the spring 21 and the position that it occupies in FIG. 3 when the connection plug 30 is pressed.

Le,ressort 21 prend appui entre l'extrémité plane et coudée de la pièce conductrice 22 plus visible figure 1, servant à fixer la broche de terre 20, et une partie annulaire 23 à l'intérieur de la pièce 18. Celle-ci, repoussée par le ressort 21, s'appuie sur la paroi 24 de la prise. La paroi 24 comprend un orifice central laissant passer l'extrémité cylindrique 18a de la pièce coulissante 18 entourant la broche 20. Dans cette position les ergots de commande 16 et 17 des commutateurs 6 et 7 ne sont pas repoussés par la partie conique 18b de la pièce 18. Ces ergots étant normalement sollicités dans cette position interdisent de façon permanente toute connexion entre les lignes de tension 4,5 et les plots 2,3 ne la fiche.The spring 21 is supported between the flat and bent end of the conductive part 22, which is more visible in FIG. 1, serving to fix the ground pin 20, and an annular part 23 inside the part 18. The latter, pushed back by the spring 21, bears on the wall 24 of the socket. The wall 24 comprises a central orifice allowing the cylindrical end 18a of the sliding part 18 to pass around the spindle 20. In this position the control pins 16 and 17 of the switches 6 and 7 are not pushed back by the conical part 18b of the Exhibit 18. These pins are normally biased in this position permanently prohibit any connection between the tension lines 4,5 and the pads 2,3 do not the plug.

La pièce de fixation 22 de la broche 20 est fixée au socle au moyen de la vis 25 en prenant appui sur des rebords appropriés de parois moulées avec le socle 15. L'extrémité de la pièce 22 est reliée électriquement par la vis 26 au fil de terre 27. La pièce de fixation 22 et la broche 20 peuvent être, rendues solidaires par tout moyen, et ne forment qu'une seule et même pièce.The fastener 22 of the pin 20 is fixed to the base by means of the screw 25, bearing on appropriate flanges of walls molded with the base 15. The end of the part 22 is electrically connected by the screw 26 to the wire. of earth 27. The fixing piece 22 and the pin 20 can be made integral by any means, and form only one and the same piece.

Bien que les plots 2,3 en contact électrique avec les sorties 10,11 des commutateurs 6,7 puissent prendre toute forme désirée pour transmettre la tension aux douilles proprement dite 28,29 recevant les broches 31,32 de la fiche 30, les plots 2,3 sont de préférence des lames conductrices attenant aux douilles correspondantes 28,29,équipées chacune d'une bille de contact. La bille de contact sollicitée par un ressort prend appui latéralement sur la broche que l'on introduit dans la douille. De cette manière la prise peut recevoir toute sorte de fiche, les cotes pouvant varier d'une fiche à l'autre dans un domaine prédéterminé.Although the pads 2,3 in electrical contact with the outputs 10,11 of the switches 6,7 can take any desired shape to transmit the voltage to the sockets proper 28,29 receiving the pins 31,32 of the plug 30, the pads 2,3 are preferably conductive strips attached to the corresponding sockets 28,29, each equipped with a contact ball. The contact ball biased by a spring bears laterally on the pin which is introduced into the socket. In this way the socket can receive any kind of plug, the dimensions can vary from one plug to another in a predetermined area.

La figure 4 montre à titre d'exemple un plot 2 relié électriquement à la douille 28 qui en plus de la partie cylindrique usuelle comprend une bille 33 sollicitée par. le ressort 34 et le poussoir 35. Un logement cylindrique 36 débouchant dans la partie cylindrique de la douille 28 par une partie conique sert de guidage au poussoir 35 et au ressort 34, la plus petite section de la partie conique guidant et retenant la bille 33. Ainsi toute broche 32 insérée dans la douille 28 repousse latéralement la bille 33 en assurant un contact franc même en dépit de toute vibration éventuelle.FIG. 4 shows by way of example a stud 2 electrically connected to the socket 28 which, in addition to the usual cylindrical part, comprises a ball 33 urged by. the spring 34 and the pusher 35. A cylindrical housing 36 opening into the cylindrical part of the sleeve 28 by a conical part serves as a guide for the pusher 35 and the spring 34, the smallest section of the conical part guiding and retaining the ball 33 Thus any pin 32 inserted in the socket 28 laterally pushes the ball 33 while ensuring a frank contact even in spite of any possible vibration.

Des blocs d'isolation 37 et 38 ont été placés entre les douilles 28,29 et les commutateurs 6,7, ces blocs étant conformés pour laisser passage aux broches 31 et 32. On notera que ces commutateurs peuvent être de tout type y compris des commutateurs à mercure que l'on bascule par la pièce de commande 18.Insulation blocks 37 and 38 have been placed between the sockets 28, 29 and the switches 6, 7, these blocks being shaped to allow passage to pins 31 and 32. It should be noted that these switches can be of any type including mercury switches which are toggled by the control panel 18.

Lorsqu'une fiche de raccordement n'est pas enfoncée dans les douilles 37,38 les ergots de commande 16 et 17 ne sont pas repoussés par la partie conique 18b de la pièce 18 de sorte qu'aucune communication électrique n'existe entre le fil de tension 4 et le plot 2 de la douille 28. Pour la même raison le plot 3 ne reçoit aucune tension du fil 5.When a connection plug is not inserted into the sockets 37, 38 the control pins 16 and 17 are not pushed back by the conical part 18b of the part 18 so that no electrical communication exists between the tension wire 4 and pin 2 of socket 28. For the same reason pin 3 receives no tension from wire 5.

Lorsqu'une fiche de raccordement 30 est connectée à la prise 1 comme dans le cas de la figure 3, l'extrémité 39 de la fiche 30 bordant la douille 40 de la fiche repousse le bord de l'extrémité cylindrique 18a de la pièce coulissante de commande 18 lorsque cette douille achève de coiffer entièrement la broche de terre 20 de la prise 1. Cette action est accompagnée de la compression du ressort de rappel 21 et de l'écartement des ergots 16 et 17 lors du passage de la partie conique 18b entre les extrémités des commutateurs 6 et 7. Le déplacement des ergots 16 et 17 entraîne la fermeture des contacts des commutateurs 6 et 7 qui ont pour effet de fermer le circuit électrique entre le fil 4 et la sortie 10 en contact électrique permanent avec la douille 28 qui passe ainsi sous tension. Il en est de même pour la douille 29 communiquant maintenant avec le fil de tension 5, l'ergot 17 ayant été repoussé par le cône 18b.When a connection plug 30 is connected to the socket 1 as in the case of FIG. 3, the end 39 of the plug 30 bordering the socket 40 of the plug pushes back the edge of the cylindrical end 18a of the sliding part control 18 when this socket completes completely covering the ground pin 20 of the socket 1. This action is accompanied by the compression of the return spring 21 and the spacing of the pins 16 and 17 during the passage of the conical part 18b between the ends of the switches 6 and 7. The displacement of the pins 16 and 17 causes the closure of the contacts of the switches 6 and 7 which have the effect of closing the electrical circuit between the wire 4 and the outlet 10 in permanent electrical contact with the socket 28 which thus turns on. It is the same for the socket 29 now communicating with the tension wire 5, the lug 17 having been pushed back by the cone 18b.

On peut donc remarquer qu'aussi lontemps que la fiche 30 est incomplètement connectée, c'est-à-dire aussi lontemps que la douille 40 ne coiffe pas entièrement la broche 20, les broches 31 et 32 ne transmettent aucune tension bien qu'en contact franc avec les douilles 28 et 29 au moyen des billes de contact. Ce n'est que lorsque la partie 39 de la fiche 30 a totalement repoussé la partie cylindrique 18a de la pièce de commande 18 que l'extrémité 18a repousse complètement les ergots de commande 16 et 17 établissant la tension aux plots de la prise. Il ne peut donc se produire aucune étincelle aux broches de la fiche.It can therefore be noted that as long as the plug 30 is incompletely connected, that is to say also as long as the socket 40 does not fully cover the pin 20, the pins 31 and 32 do not transmit any voltage although in frank contact with sockets 28 and 29 by means of contact balls. It is only when the part 39 of the plug 30 has completely pushed back the cylindrical part 18a of the control piece 18 that the end 18a completely pushes back the control pins 16 and 17 establishing the tension at the studs of the socket. There can therefore be no spark at the pins of the plug.

Bien que l'on n'ait décrit qu'un mode de réalisation on comprendra que de multiples additions et substitutions peuvent être apportées aux différents organes décrits sans sortir du cadre général de l'invention. C'est ainsi que la partie cylindrique 18a peut être remplacée par toute forme désirée et n'être accessible que par une partie de la fiche agissant comme une clé dans une serrure constituée par un passage donnant accès à la pièce 18. De même la pièce 18 peut même en position de repos ne pas recouvrir la partie apparente de la broche de terre. L'invention s'applique de même à des prises dont une seule douille ou broche est ainsi isolée de la ligne de tension qui lui correspond. En particulier dans le das on Ja fiche comporte une partie servant de clé, celle-ci peut être de longueur inférieure à ses broches.Although only one embodiment has been described, it will be understood that multiple additions and substitutions can be made to the various organs described without departing from the general scope of the invention. Thus the cylindrical part 18a can be replaced by any desired shape and be accessible only by a part of the plug acting as a key in a lock constituted by a passage giving access to the part 18. Similarly the part 18 may even in the rest position not cover the exposed part of the earth pin. The invention also applies to sockets of which a single socket or pin is thus isolated from the line of tension which corresponds to it. In particular in the das on Ja sheet has a part serving as a key, this may be shorter than its pins.
