Description

L'invention concerne une prise pour connexion électrique avec une fiche ou similaire, et constituant le socle d'une prise de courant ou la prise mobile d'un prolongateur ou d'un connecteur.The invention relates to a socket for electrical connection with a plug or the like, and constituting the base of a socket or the mobile socket of an extension cable or a connector.

Il est connu de concevoir un socle de prise de courant pourvu de plusieurs contacts disposés dans des logements ménagés dans un support selon une circonférence, l'un d'entre eux étant toutefois central, tandis qu'au moins un disque de sécurité en matière isolante monté pivotant sur le support de contacts de manière coaxiale à la circonférence des contacts, est muni d'ajours destinés à être traversés par les contacts de la fiche et est aménagé de manière à être entraîné en rotation par la fiche pour passer d'une position initiale dans laquelle les logements des contacts circonférentiels sont au moins en grande partie obturés à une position de connexion en fin de rotation qui découvre au moins certains desdits logements de contacts.It is known to design a socket outlet provided with several contacts arranged in housings formed in a support along a circumference, one of them being however central, while at least one safety disc made of insulating material pivotally mounted on the contact support coaxially to the circumference of the contacts, is provided with openings intended to be crossed by the contacts of the plug and is arranged so as to be rotated by the plug to pass from a position initial in which the housings of the circumferential contacts are at least largely closed at a connection position at the end of rotation which uncovers at least some of said contact housings.

C'est par exemple le cas montré dans les brevets FR-2 680 607 et 2 680 608, ce dernier étant en outre pourvu d'un disque complémentaire afin d'augmenter les possibilités de positionnement des contacts affectés à diverses alimentations en courant.This is for example the case shown in patents FR-2 680 607 and 2 680 608, the latter being furthermore provided with an additional disk in order to increase the possibilities of positioning of the contacts assigned to various current supplies.

Les dispositifs mentionnés ci-avant concernent plus spécialement des socles de prise de courant mais on peut bien sûr généraliser à d'autres systèmes de connexion électrique, comme mentionné ci-avant, tels qu'une prise mobile d'un connecteur électrique (prévue pour s'accoupler avec le socle du connecteur dont les organes de contact sont généralement semblables à ceux d'une fiche) ou la prise mobile d'un prolongateur (prévue pour s'accoupler avec une fiche), d'où l'expression plus générale utilisée de prise.The devices mentioned above relate more specifically to socket outlets, but we can of course generalize to other electrical connection systems, as mentioned above, such as a mobile socket of an electrical connector (provided for mate with the base of the connector, the contact members of which are generally similar to those of a plug) or the mobile socket of an extension cable (designed to mate with a plug), hence the more general expression used plug.

Il s'agit généralement d'une prise à contacts multiples destinés à s'accoupler avec une fiche ou similaire munie de contacts sous forme de broches.It is generally a socket with multiple contacts intended to be coupled with a plug or the like provided with contacts in the form of pins.

Dans tous ces dispositifs connus, il est généralement prévu un contact de terre disposé au centre et celui-ci n'est pas protégé comme le sont les autres contacts par le ou les disques. Le contact de terre n'étant jamais sous tension, la nécessité de le protéger n'apparaissait pas indispensable et ce, d'autant plus qu'il semblait très difficile de concevoir un moyen d'obturation dégageable comme pour les autres contacts lors de la rotation du disque, du fait de la position centrale dudit contact.In all these known devices, there is generally provided an earth contact disposed in the center and this is not protected as are the other contacts by the disc (s). Since the earth contact is never energized, the need to protect it did not appear to be essential, all the more so since it seemed very difficult to design a releasable closure means as for the other contacts during the rotation of the disc, due to the central position of said contact.

Toutefois, et bien que ces dispositifs sont en outre souvent pouvus d'un couvercle, il peut être gênant dans certains cas de laisser le logement central libre car il peut être souillé et/ou en partie bouché, notamment lors de l'aménagement de locaux en cours de fabrication ou de rénovation de telle sorte que le contact de terre risque de ne plus jouer sa fonction alors que le dispositif est en lui-même parfaitement fonctionnel.However, and although these devices are also often provided with a cover, it can be inconvenient in certain cases to leave the central housing free because it can be soiled and / or partially blocked, in particular when fitting out premises. during manufacture or renovation so that the earth contact may no longer perform its function while the device is in itself perfectly functional.

C'est la raison pour laquelle l'invention propose une prise du type précité, mais qui est notamment remarquable en ce qu'un obturateur du logement central est monté mobile dans ou sur le support de contacts et que des moyens conjugués d'entraînement sont prévus entre ledit obturateur et le disque de sécurité de manière telle qu'en position initiale du disque de sécurité, le logement du contact central est obturé par ledit obturateur tandis que celui-ci dégage ledit logement au cours de la rotation du disque de sécurité par coopération des moyens conjugués d'entraînement.This is the reason why the invention proposes a socket of the aforementioned type, but which is in particular remarkable in that a shutter of the central housing is mounted mobile in or on the contact support and that combined drive means are provided between said shutter and the safety disc so that in the initial position of the safety disc, the housing of the central contact is closed by said shutter while the latter releases said housing during the rotation of the safety disc by cooperation of combined training means.

Selon un mode de réalisation l'obturateur est monté mobile radialement dans le support, tandis que les moyens conjugués d'entraînement se présentent sous la forme d'un ergot d'entraînement prévu sous le disque de sécurité et d'une rainure oblique ménagée dans l'obturateur de telle sorte que la rotation du disque entraîne un mouvement translatif radial de l'obturateur et permet de passer d'une position d'obturation du logement central à une position de dégagement et réciproquement.According to one embodiment, the shutter is mounted to move radially in the support, while the combined drive means are in the form of a drive lug provided under the safety disc and an oblique groove formed in the shutter so that the rotation of the disc causes a radial translational movement of the shutter and makes it possible to pass from a position for closing the central housing to a release position and vice versa.

Selon une particularité, dans ce cas, la rainure oblique présente à au moins l'une de ses extrémités, un petit prolongement dans le sens du mouvement rotatif pour tolérer un petit jeu à la rotation du disque de sécurité, sans action sur le mouvement translatif de l'obturateur.According to one feature, in this case, the oblique groove has at least one of its ends, a small extension in the direction of the rotary movement to tolerate a small play in the rotation of the safety disc, without action on the translational movement. shutter.

De préférence l'obturateur est monté mobile dans une rainure radiale du support de contacts qui débouche au-dessus ou dans la partie supérieure du logement du contact central.Preferably the shutter is movably mounted in a radial groove of the contact support which opens above or in the upper part of the housing of the central contact.

Selon un autre mode de réalisation, l'obturateur se présente sous la forme d'une barrette montée libre en rotation à l'une de ses extrémités, au voisinage de la circonférence périphérique du support de contacts, tandis qu'elle présente à son autre extrémité une rainure ou lumière par exemple axiale et oblongue destinée à coopérer avec un ergot aménagé sous le disque de sécurité, ledit ergot et ladite lumière constituant les moyens d'entraînement de l'obturateur de manière telle qu'une rotation du disque de sécurité entraîne une rotation de l'obturateur sous forme de barrette et permet de passer d'une position d'obturation du logement central par la partie médiane de la barrette, à une position de dégagement et réciproquement et selon une particularité, la partie médiane de l'obturateur en forme de barrette présente un renflement.According to another embodiment, the shutter is in the form of a bar mounted freely in rotation at one of its ends, in the vicinity of the peripheral circumference of the contact support, while it has at its other end a groove or lumen, for example axial and oblong intended to cooperate with a lug fitted under the safety disk, said lug and said light constituting the shutter drive means in such a way that a rotation of the safety disc causes a rotation of the shutter in the form of a bar and makes it possible to pass from 'A closed position of the central housing by the middle part of the bar, in a release position and vice versa and according to one feature, the middle part of the bar-shaped shutter has a bulge.

L'invention sera bien comprise à la lecture de la description qui va suivre et qui se réfère aux dessins annexés dans lesquels:

  • la figure 1 est une vue en éclaté et en perspective d'un socle de prise de courant selon l'invention,
  • la figure 2 est une vue de dessus du dispositif de la figure 1, une fois monté,

  • la figure 4 est un agrandissement du détail cerclé de la figure 3,
  • la figure 5 correspond à la figure 4, mais en position dégagée de l'obturateur.
  • les figures 6 et 7 représentent les divers éléments essentiels en position fermée et respectivement ouverte d'un autre mode de réalisation.
The invention will be clearly understood on reading the description which follows and which refers to the appended drawings in which:
  • FIG. 1 is an exploded and perspective view of a socket outlet according to the invention,
  • FIG. 2 is a top view of the device of FIG. 1, once mounted,
  • FIG. 3 is a section on III-III of FIG. 2, the housings of the contacts being closed by the safety disc and the shutter,
  • FIG. 4 is an enlargement of the detail circled in FIG. 3,
  • Figure 5 corresponds to Figure 4, but in the released position of the shutter.
  • Figures 6 and 7 show the various essential elements in the closed and respectively open position of another embodiment.

Le socle de prise de courant représenté comporte de manière connue un support isolant 1 pourvu notamment, de logements tels que 2 pour des ressorts d'éjection destinés à solliciter une rondelle d'éjection et de verrouillage 3, et de plusieurs logements sous forme de puits 4a à 4e, dont ici quatre, 4a à 4d, sont disposés sensiblement sur une circonférence et un autre 4e de façon centrale.The socket outlet shown comprises in known manner an insulating support 1 provided in particular with housings such as 2 for ejection springs intended to urge an ejection and locking washer 3, and several housings in the form of wells 4a to 4e, of which here four, 4a to 4d, are arranged substantially on one circumference and another 4th centrally.

Les contacts prévus dans les logements circonférentiels sont, par exemple, les contacts de phase et le neutre, tandis que le logement central est plus particulièrement destiné à recevoir le contact de terre.The contacts provided in the circumferential housings are, for example, the phase contacts and the neutral, while the central housing is more particularly intended to receive the earth contact.

Le socle représenté comporte en outre un disque de sécurité 5 et un disque complémentaire 6, dit de codage, entre lesquels est prévu ici un cliquet de codage 7.The base shown also comprises a safety disk 5 and an additional disk 6, known as a coding disk, between which a coding pawl 7 is provided here.

Les disques 5 et 6 sont montés sur le support 1 au moyen, par exemple, d'une virole 8.The discs 5 and 6 are mounted on the support 1 by means, for example, of a ferrule 8.

En outre, on peut voir sur les dessins qu'entre le support 1 et le disque de sécurité 5, est prévu un obturateur 9.Furthermore, it can be seen in the drawings that a shutter 9 is provided between the support 1 and the safety disk 5.

Les disques 5 et 6 sont pourvus de lumières 10a à 10d et respectivement 11a à 11d correspondant aux emplacements des logements 4a à 4d du support 1 afin de pouvoir, par rotation des disques, juxtaposer lesdites lumières avec lesdits logements.The discs 5 and 6 are provided with lights 10a to 10d and respectively 11a to 11d corresponding to the locations of the housings 4a to 4d of the support 1 so as to be able, by rotation of the discs, to juxtapose said lights with said housings.

Par contre, on comprend que les disques 5 et 6 cachent et protègent en position de repos les logements 4a à 4d et donc les contacts qu'ils contiennent, comme représenté sur la figure 2.On the other hand, it is understood that the discs 5 and 6 hide and protect in the rest position the housings 4a to 4d and therefore the contacts which they contain, as shown in FIG. 2.

Le disque complémentaire de codage 6 n'est pas obligatoire et correspond à un mode de réalisation qui permet notamment par un verrouillage selon diverses positions relatives avec le disque de sécurité 5 au moyen du cliquet 7, d'utiliser un même socle pour plusieurs types de courant, comme déjà dit à propos du brevet FR 2 680 608 déjà cité.The complementary coding disc 6 is not compulsory and corresponds to an embodiment which allows in particular by locking in various relative positions with the safety disc 5 by means of the pawl 7, to use the same base for several types of current, as already said in connection with the patent FR 2 680 608 already cited.

On remarquera en outre que les disques 5 et 6 présentent un ajour central respectivement 10e et 11e pour le passage du contact terre de la fiche.It will also be noted that the discs 5 and 6 have a central aperture respectively 10th and 11th for the passage of the ground contact of the plug.

L'obturateur 9, comme le montre bien la figure 1, est monté coulissant radialement dans une rainure correspondante 12 du support 1 qui débouche dans ou au-dessus du logement 4e.The shutter 9, as shown in FIG. 1, is slidably mounted radially in a corresponding groove 12 in the support 1 which opens into or above the housing 4e.

Pour un meilleur guidage et/ou maintien, ledit obturateur présente une saillie 13 destinée à coulisser dans une rainure correspondante 14 du support 1.For better guidance and / or maintenance, said shutter has a projection 13 intended to slide in a corresponding groove 14 of the support 1.

En outre, on constate que ledit obturateur est pourvu d'une protubérance arrondie 15 et d'une rainure ou fente oblique 16.Furthermore, it can be seen that said shutter is provided with a rounded protuberance 15 and an oblique groove or slot 16.

On comprend parfaitement qu'en coulissant dans la rainure 12, l'obturateur 9 peut passer d'une position dans laquelle il libère le logement 4e ou au contraire, il l'obture.It is perfectly understood that by sliding in the groove 12, the shutter 9 can pass from a position in which it releases the 4th housing or on the contrary, it closes it.

Pour ce faire, le disque 5 présente un ergot 17 non visible sur les figures 1 et 2 mais visible sur les figures 3 à 5, destiné à venir dans la rainure 16 de l'obturateur.To do this, the disc 5 has a lug 17 not visible in Figures 1 and 2 but visible in Figures 3 to 5, intended to come into the groove 16 of the shutter.

Ainsi, en tournant les disques 5, 6, l'effet combiné de l'ergot 17 du disque 5 et de la rainure oblique 16 de l'obturateur, est semblable à un effet de came qui transforme le mouvement rotatif des disques en mouvement translatif dudit l'obturateur.Thus, by turning the discs 5, 6, the combined effect of the lug 17 of the disc 5 and the oblique groove 16 of the shutter, is similar to a cam effect which transforms the rotary movement of the discs into translational movement said shutter.

En particulier dans le mode de réalisation représenté, la rainure 16 de l'obturateur 9 présente à l'une de ses extrémités (mais elle pourrait en avoir un autre, symétrique du premier à son autre extrémité), un prolongement 18 dans le sens du mouvement rotatif pour tolérer un petit jeu à la rotation du disque de sécurité 5, sans action sur le mouvement translatif dudit obturateur 9 et éviter ainsi un mouvement intempestif de celui-ci pour des petits mouvements des disques.In particular in the embodiment shown, the groove 16 of the shutter 9 has at one of its ends (but it could have another, symmetrical from the first to its other end), an extension 18 in the direction of rotary movement to tolerate a small play in the rotation of the safety disc 5, without action on the translational movement of said shutter 9 and thus avoid inadvertent movement of the latter for small movements of the discs.

La figure 3 et son détail agrandi de la figure 4 montre bien une position de repos dans laquelle l'obturateur 9 obture l'entrée du logement 4e du support 1.FIG. 3 and its enlarged detail of FIG. 4 clearly shows a rest position in which the shutter 9 closes the entry of the housing 4e of the support 1.

Au contraire, dans son autre position représentée à la figure 5, l'obturateur 9 dégage ledit logement 4e.On the contrary, in its other position shown in FIG. 5, the shutter 9 releases said housing 4e.

En conséquence, au repos, tous les logements 4a à 4e peuvent être masqués ou obturés par les disques 5 et 6 et par l'obturateur 9, alors qu'après enfichage et rotation de la fiche, on découvre tous les logements des contacts, y compris celui de la terre, et une simple poussée de la fiche permet la connexion des contacts de la fiche et du socle. Une déconnexion par rotation inverse provoquera bien entendu une nouvelle obturation des logements des contacts par translation inverse de l'obturateur 9.Consequently, at rest, all the housings 4a to 4e can be hidden or closed by the discs 5 and 6 and by the shutter 9, while after plugging in and rotating the plug, all of the contact housings are discovered, including including that of the earth, and a simple push of the plug allows the connection of the contacts of the plug and the base. A disconnection by reverse rotation will naturally cause a new closure of the contact housings by reverse translation of the shutter 9.

Les figures 6 et 7 montrent un autre mode de réalisation dont les éléments de même nature que ceux précédemment décrits portent les mêmes références mais avec un accent.Figures 6 and 7 show another embodiment whose elements of the same nature as those previously described have the same references but with an accent.

Sur les dessins, on peut voir en plan une représentation schématique d'un support 1' et de manière dissociée et en plan, également les disques 5' et 6' en position respectivement de repos (figure 6), c'est-à-dire contacts masqués et en position au contraire de dégagement (figure 7).In the drawings, we can see in plan a schematic representation of a support 1 'and in a separate manner and in plan, also the disks 5' and 6 'in the rest position respectively (Figure 6), that is to say say contacts concealed and in the opposite release position (Figure 7).

Dans ce mode de réalisation, l'obturateur 9' se présente sous la forme d'une barrette articulée de façon libre en rotation à l'une de ses extrémités 19, tandis que son autre extrémité présente une rainure ou lumière oblongue 16' dans l'axe de la barrette, destinée à coopérer avec un ergot du disque 5', dont on a représenté la position en 17' sur ce dernier (position également schématisée dans la lumière 16' de l'obturateur). Toutefois, on comprend que la lumière oblongue 16' pourrait être prévue du côté de l'extrémité d'articulation 19.In this embodiment, the shutter 9 ′ is in the form of a bar articulated so as to rotate freely at one of its ends 19, while its other end has an oblong groove or slot 16 ′ in the 'axis of the bar, intended to cooperate with a lug of the disc 5', whose position has been shown in 17 'on the latter (position also shown schematically in the lumen 16' of the shutter). However, it is understood that the oblong opening 16 'could be provided on the side of the articulation end 19.

La partie médiane de l'obturateur 9' présente une protubérance ou renflement 15' arrondi destiné à venir obturer le logement central 4e du support 1', comme le montre la figure 6, les ajours 10'a à 10'e et 11'a à 11'e des disques 5 et respectivement 6 n'étant pas, pour cette position, dans l'alignement des logements 4'a à 4'd du support 1'.The middle part of the shutter 9 ′ has a rounded protuberance or bulge 15 ′ intended to close off the central housing 4e of the support 1 ′, as shown in FIG. 6, the openings 10 ′ to 10 ′ and 11 ′ a at 11′e of the disks 5 and respectively 6 not being, for this position, in alignment with the housings 4 ′ a to 4 ′ of the support 1 ′.

On comprend que la rotation des disques 5' et 6' entraîne par la coopération de l'ergot 17' du disque 5' et de la lumière 16' de l'obturateur 9', un passage de la position de la figure 6 à celle de la position de la figure 7 et réciproquement, les ajours 10'a-10'd et 11'a-11'd sur la figure 7 se superposant alors aux logements 4'a-4'e du support 1'.We understand that the rotation of the discs 5 'and 6' causes by the cooperation of the lug 17 'of the disc 5' and the light 16 'of the shutter 9', a transition from the position of Figure 6 to that from the position of Figure 7 and vice versa, the openings 10'a-10'd and 11'a-11'd in Figure 7 then overlapping the housing 4'a-4'e of the support 1 '.

Comme précisé ci-avant, le support 1 ou 1' peut être celui d'un socle de prise de courant, mais aussi celui d'une prise mobile prévue pour se connecter soit à un socle de connecteur, soit à une fiche de prolongateur, d'où l'expression générale utilisée, comme déjà dit, de prise, tout en généralisant aussi la fiche qui peut donc constituer le socle d'un connecteur.As specified above, the support 1 or 1 ′ can be that of a socket outlet, but also that of a mobile socket provided for connecting either to a connector socket or to an extension plug, hence the general expression used, as already said, socket, while also generalizing the plug which can therefore constitute the base of a connector.
