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 an electrical outlet or the mobile socket of an extension cable or 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 entraíné 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 of several contacts arranged in housings arranged in a support according to 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 contact circumference, has openings intended to be crossed by the plug contacts and is arranged to be rotated by the plug to move from an initial position in which the housings of the circumferential contacts are at less 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, au nom de la demanderesse 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 the patents FR-2 680 607 and 2,680,608, in the name of the plaintiff, the latter being also provided with an additional disc to increase the possibilities of positioning the contacts assigned to various power 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 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 (intended for mate with the connector base including the contact members are generally similar to those of a plug) or the mobile socket an extension (designed to mate with a plug), hence the more general expression used.

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 multiple contact socket intended to be coupled with a plug or similar fitted with contacts under pin shape.

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 a earth contact arranged in the center and this is not protected as the other contacts are by the disc (s). Earth contact never being energized, the need to protect it appeared not essential, especially since it seemed very difficult to design a releasable sealing means as for other contacts when rotating the disc, due to the position central 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 may have a cover, it can be inconvenient in some cases to leave free central housing because it can be soiled and / or partially clogged, especially when fitting out premises during manufacture or renovation so that the earth contact may stop playing 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'entraínement 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'entraínement.This is the reason why the invention proposes taking the aforementioned type, but which is notably remarkable in that a shutter of the central housing is mounted mobile in or on the support of contacts and that combined means of training are provided between said shutter and the safety disk so that initial position of the safety disk, the central contact housing is closed by said shutter while the latter releases said housing during rotation of the safety disk by cooperation combined means of training.

Selon un mode de réalisation l'obturateur est monté mobile radialement dans le support, tandis que les moyens conjugués d'entraínement se présentent sous la forme d'un ergot d'entraínement prévu sous le disque de sécurité et d'une rainure oblique ménagée dans l'obturateur de telle sorte que la rotation du disque entraíne 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 mobile radially in the support, while the combined drive means are in the form of a planned training pin under the safety disk and an oblique groove in the shutter so that the rotation of the disc causes a translational radial movement of the shutter and allows passing from one closed position of the central housing to a release position and reciprocally.

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 a 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 rotation of the safety disc, without action on the translational movement of the 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 groove radial of the contact support which opens above or into the upper part of the central contact housing.

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'entraínement de l'obturateur de manière telle qu'une rotation du disque de sécurité entraíne 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 presented in the form of a bar mounted freely in rotation at one of its ends, near the peripheral circumference of the support of contacts, while it has at its other end a groove or light, 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 so such that a rotation of the safety disc causes a rotation of the shutter in the form of bar and allows to pass from a position closing the central housing by the middle part of the bar, to a release position and vice versa and according to a particularity, the middle part of the bar-shaped shutter is present 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 3 est une coupe selon III-III de la figure 2, les logements des contacts étant obturés par le disque de sécurité et l'obturateur,
  • 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 includes so known an insulating support 1 provided in particular with housings such as 2 for ejection springs intended to load an ejection washer and locking 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, phase and neutral contacts, while housing central is more particularly intended to receive the contact earthen.

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 further comprises a safety disk 5 and an additional disc 6, called a coding disc, between which is provided here a coding pawl 7.

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, by 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 between the support 1 and the safety disk 5, a shutter 9 is provided.

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 in order 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.However, we understand that discs 5 and 6 hide and protect in the rest position the housings 4a to 4d and therefore the contacts they contain, as shown in Figure 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 additional coding disc 6 is not compulsory and corresponds to an embodiment which allows in particular by locking in various relative positions with the safety disk 5 using the ratchet 7, use the same base for several types of current, as already said in connection with 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 opening respectively 10th and 11th for the passage of the contact plug earth.

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 Figure 1, is mounted sliding radially in a corresponding groove 12 of the support 1 which opens into or above the 4th housing.

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 support 1.

En outre, on constate que ledit obturateur est pourvu d'une protubérance arrondie 15 et d'une rainure ou fente oblique 16.In addition, 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 which is not visible in Figures 1 and 2 but visible in Figures 3 to 5, intended for 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 translating moving discs of 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 present at one of its ends (but it could have another, symmetrical from the first to the other end), an extension 18 in the direction of the rotary movement for tolerate a small play with the rotation of the safety disk 5, without action on the translational movement of said shutter 9 and thus avoid an untimely movement of it 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.Figure 3 and its enlarged detail of Figure 4 shows well a rest position in which the shutter 9 closes the entry of the 4th slot of 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 represented in the figure 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 masked or closed by the discs 5 and 6 and by the shutter 9, whereas after inserting and rotating the plug, we discover all contact housings, including the earth one, and a simple pushing the plug allows connection of the plug contacts and the basement. Disconnection by reverse rotation will of course cause a new closure of the contact housings by translation reverse 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 of which elements of the same nature as those previously described carry 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). On the drawings, we can see in plan a representation schematic of a support 1 'and in a separate manner and in plan, also the 5 'and 6' discs in the rest position respectively (figure 6), that is to say contacts concealed and in position in contrast to release (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 presented under the shape of a bar freely articulated in rotation to one of its ends 19, while its other end has a oblong groove or slot 16 'in the axis of the bar, intended for cooperate with a lug of the disc 5 ', the position of which has been shown in 17 'on the latter (position also shown schematically in the light 16 'of the shutter). However, we understand that the oblong light 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 protuberance or 15 'rounded bulge intended to close off the central housing 4th of support 1 ', as shown in Figure 6, the openings 10'a to 10'e and 11'a to 11'e of the disks 5 and 6 respectively not being, for this position, in alignment with the housings 4'a to 4'd of the support 1 '.

On comprend que la rotation des disques 5' et 6' entraíne 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 disks 5 'and 6' causes the cooperation of the lug 17 'of the disc 5' and the light 16 'of the shutter 9 ', a passage from the position of FIG. 6 to that of 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 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 a socket outlet, but also that of a mobile outlet designed to connect either to a connector socket or to a extension plug, hence the general expression used, as already says, taken, while also generalizing the plug which can therefore constitute the base of a connector.

Socket for electrical connection to a plug or the like, and constituting the base of a power socket or the mobile socket of an extension or of a connector, provided with a plurality of contacts disposed in housings (4a-4e; 4'a-4'e) formed in an insulating support (1; 1') along a circumference, but with one of them (4e; 4'e) being central, whereas at least one safety disc (5; 5') made of insulating material mounted pivoting on the contact support (1; 1') coaxial with the circumference of the contacts, is provided with openings (10a-10e; 10'a-10'e) designed for passage by the contacts of the plug and is arranged so as to be entrained in rotation by the plug in order to pass from an initial position in which the housings of the circumferential contacts are at least largely blocked to a connection position at the end of rotation which uncovers at least some of said contact housings, characterised in that a shutter (9; 9') of the central housing (4e; 4'e) is fitted so that it can move in or on the contact support (1; 1') and in that paired means of entrainment are provided between said shutter (9; 9') and the safety disc (5; 5') such that in the initial position of the safety disc, the housing (4e; 4'e) of the central contact is blocked by said shutter while the latter unblocks said housing in the course of the rotation of the safety disc through cooperation of the paired means of entrainment.
  2. Socket according to claim 1, characterised in that the shutter (9) is fitted so that it can move radially in the support (1), while the paired means of entrainment take the form of an entrainment lug (17) provided under the safety disc (5) and of an oblique slot (16) formed in the shutter (9) such that the rotation of the disc produces a radial translation movement of the shutter and makes it possible to pass from a position in which the central housing (4e) is blocked to a position in which it is unblocked and vice versa.
  3. Socket according to claim 2, characterised in that the oblique slot (16) exhibits at least at one of its ends a small extension (18) in the direction of the rotary movement to allow for a small amount of play in the rotation of the safety disc (5), without affecting the translation movement of the shutter (9).
  4. Socket according to one of claims 2 and 3, characterised in that the shutter (9) is fitted so that it can move in a radial slot (14) located in the contact support (1) and debouching above or in the upper portion of the housing (4e) of the central contact.
  5. Socket according to claim 1, characterised in that the shutter (9') takes the form of a bar fitted so that it is free to rotate at one (19) of its ends in the vicinity of the peripheral circumference of the contact support (1'), whereas at its other end it exhibits a slot or opening (16') designed to cooperate with a lug (17') arranged under the safety disc (5'), said lug and said opening constituting the means of entrainment of the shutter (9') such that a rotation of the safety disc produces a rotation of the shutter in the form of a bar and makes it possible to pass from a position in which the central housing (4'e) is blocked by the median portion of the bar to a position in which it is unblocked and vice versa.
  6. Socket according to claim 5, characterised in that the median portion of the shutter in the form of a bar exhibits a swelling (15').
