Abstract

Electrical connection element (1) provided with peripherally distributed electrical contacts designed to collaborate with the corresponding contact pins (5b) of a plug (2), a rotary safety disc (6) being provided and having peripheral perforations the number and position of which are chosen to, on the one hand, at rest, conceal the peripheral contacts of the connection element and, on the other hand, be superimposed therewith when the disc driven by the pins of the plug is rotated, whereas sealing blocks (9b) are positioned under the safety disc so as to seal off the peripheral perforations thereof in the rest position. The sealing blocks (9b) are positioned on a sealing disc (8) also provided with perforations, and which is formed under the safety disc (6) and mounted fixed in terms of rotation and able to move in terms of translation against the action of elastic means (10) which urge it towards the safety disc (6).

Description

L'invention concerne un élément de connexion électrique étanche, constituant, par exemple, le socle d'une prise de courant, ou la prise mobile d'un prolongateur ou d'un connecteur.The invention relates to a sealed electrical connection element, constituting, for example, the base of a socket, or the mobile socket of an extension or a connector.

Un élément de connexion connu pour les applications précitées est généralement pourvu de contacts électriques montés dans un bloc isolant, et répartis périphériquement et qui sont prévus pour coopérer avec les broches de contact correspondantes d'une fiche, après accouplement de ladite fiche avec ledit élément au cours d'au moins un premier mouvement de translation suivi d'une rotation et d'une seconde translation, tandis qu'un disque de sécurité rotatif est aménagé au-dessus du bloc isolant de l'élément de connexion et comporte des ajours périphériques dont le nombre et le positionnement sont choisis de manière, d'une part, à cacher au repos les contacts périphériques de l'élément de connexion et, d'autre part, à se superposer à ceux-ci après la rotation du disque entraîné par les broches de la fiche qui ont été introduites dans lesdits ajours du disque au cours du premier mouvement de translation.A known connection element for the aforementioned applications is generally provided with electrical contacts mounted in an insulating block, and distributed peripherally and which are provided to cooperate with the corresponding contact pins of a plug, after coupling of said plug with said element to during at least a first translational movement followed by a rotation and a second translation, while a rotating safety disc is arranged above the insulating block of the connection element and comprises peripheral openings whose the number and the positioning are chosen so as, on the one hand, to hide at rest the peripheral contacts of the connection element and, on the other hand, to be superimposed on them after the rotation of the disk driven by the pins of the plug which have been introduced into said openings of the disk during the first translational movement.

Afin d'assurer l'étanchéité au repos de tels éléments, ils comportent généralement un couvercle pivotant et verrouillable sur un carter dans lequel sont disposés le bloc isolant et les contacts, ledit couvercle venant se rabattre de manière étanche sur ledit carter en position de repos.In order to ensure the sealing at rest of such elements, they generally comprise a pivoting lid and lockable on a housing in which are disposed the insulating block and the contacts, said cover being folded sealingly on said housing in the rest position .

Outre les différents problèmes à résoudre en vue d'assurer avec un tel couvercle une bonne étanchéité (efficacité des joints, ajustement de la fermeture, etc.), il y a l'inconvénient majeur d'obliger l'utilisateur à fermer le couvercle après utilisation, à moins d'une fermeture automatique par un moyen élastique mais qui oblige alors l'utilisateur à ouvrir ledit couvercle et à le maintenir dans cette position à l'encontre de son moyen élastique au cours des manoeuvres d'accouplement de la fiche et de l'élément.In addition to the various problems to be solved in order to ensure with such a lid a good seal (effectiveness of the joints, adjustment of the closure, etc.), there is the major disadvantage of requiring the user to close the lid after use, unless an automatic closure by an elastic means but which then forces the user to open said lid and hold it in this position against its elastic means during the coupling maneuvers of the plug and of the element.

Il a aussi été imaginé, comme décrit dans le document DE-9013436U1 , un élément de connexion du type général précité comportant en outre des plots d'étanchéité qui sont aménagés sous le disque de sécurité en nombre égal et disposés de la même manière que les ajours périphériques de ce dernier de façon à venir obturer de manière étanche lesdits ajours en position de repos sous l'effet de moyens élastiques, lesdits plots d'étanchéité pouvant être dégagés desdits ajours périphériques par les broches de la fiche.It was also imagined, as described in the document DE-9013436U1 , a connecting element of the aforementioned general type further comprising sealing pads which are arranged under the security disk in equal number and arranged in the same manner as the peripheral openings of the latter so as to sealingly close said opening in the rest position under the effect of elastic means, said sealing pads can be released from said peripheral openings by the pins of the plug.

Toutefois, dans ce dispositif, les plots d'étanchéité sont aménagés dans le bloc isolant pourvu des contacts.However, in this device, the sealing pads are arranged in the insulating block provided with the contacts.

Comme il faut autant de plots d'étanchéité que de contacts, on limite d'autant dans l'isolant le nombre d'emplacements et de logements possibles pour les contacts, ce qui peut s'avérer rédhibitoire pour des éléments de connexion nécessitant plus de deux contacts et/ou pour des dispositifs de taille réduite et/ou dont la répartition et le positionnement des contacts sont conditionnés par des contraintes techniques, en particulier pour permettre de prévoir un grand nombre de courants distincts tout en évitant les risques d'incompatibilité électrique.Since it takes as many sealing pads as contacts, the insulation in the number of locations and possible housing for the contacts is limited in the same way, which can be prohibitive for connection elements requiring more than two contacts and / or for devices of reduced size and / or whose distribution and positioning of the contacts are conditioned by technical constraints, in particular to allow to provide a large number of separate currents while avoiding the risks of electrical incompatibility .

Pour notamment pallier cet inconvénient, les inventeurs ont imaginé un élément de connexion du type précité muni de plots d'étanchéité, mais qui est notamment remarquable en ce que les plots d'étanchéité sont disposés sur un disque d'étanchéité qui est aménagé sous le disque de sécurité, qui comporte en outre des ajours périphériques au moins en nombre égal et disposés de la même manière que les ajours périphériques du disque de sécurité, tout en étant décalés angulairement par rapport auxdits plots d'étanchéité, et qui est monté fixe en rotation et mobile en translation à l'encontre de moyens élastiques qui le sollicitent vers le disque de sécurité, afin d'assurer une position de repos dans laquelle les plots d'étanchéité obturent lesdits ajours périphériques du disque de sécurité, tandis que le disque d'étanchéité peut être écarté du disque de sécurité par les broches de la fiche au cours du premier mouvement de translation de telle sorte que les plots d'étanchéité soient dégagés des ajours du disque de sécurité qui peut ainsi être entraîné en rotation par lesdites broches, lesquelles peuvent alors venir en position de connexion en traversant les ajours périphériques du disque d'étanchéité, ce dernier reprenant sa position d'obturation étanche au cours du désaccouplement de la fiche et dudit élément, sous l'effet desdits moyens élastiques dont il est muni.In particular to overcome this drawback, the inventors have devised a connection element of the aforementioned type provided with sealing pads, but which is particularly remarkable in that the sealing pads are arranged on a sealing disk which is arranged under the safety disk, which further comprises peripheral openings at least in equal numbers and arranged in the same manner as the peripheral openings of the safety disk, while being offset angularly relative to said sealing pads, and which is fixedly mounted in rotation and movable in translation against resilient means urging it towards the safety disc, to ensure a rest position in which the sealing studs seal said peripheral openings of the safety disc, while the disc of seal can be discarded from the safety disc by the pins of the plug during the first translation movement of t it ensures that the sealing pads are clear of openings of the safety disc which can thus be rotated by said pins, which can then come into the connection position through the peripheral openings of the sealing disc, the latter taking up its sealing position during the uncoupling of the plug and said element, under the effect of said elastic means which it is provided.

De la sorte, on assure une étanchéité automatique avec un dispositif simplifié dont les plots d'étanchéité n'occupent en outre aucune place dans l'isolant.In this way, it ensures an automatic seal with a simplified device whose sealing pads occupy no further place in the insulation.

Avantageusement, le disque de sécurité est pourvu d'un prolongement central sur lequel est monté mobile en translation le disque d'étanchéité muni à cet effet d'un ajour central de forme conjuguée à celle du prolongement.Advantageously, the safety disc is provided with a central extension on which is mounted movably in translation the sealing disc provided for this purpose with a central opening of shape conjugate to that of the extension.

Selon un mode de réalisation, les moyens élastiques qui sollicitent le disque d'étanchéité vers le disque de sécurité sont constitués par des ressorts disposés sensiblement sous chacun desdits plots.According to one embodiment, the resilient means that urge the sealing disc towards the safety disc consist of springs disposed substantially under each of said pads.

En outre, par exemple, le disque de sécurité et le bloc isolant sont pourvus de moyens pour assurer l'étanchéité du disque de sécurité à sa périphérie, lesdits moyens pour assurer l'étanchéité étant par exemple constitués par une gorge périphérique qui est ménagée dans un fourreau entourant le bloc isolant de l'élément et dans lequel tourne le disque de sécurité, et par un joint annulaire logé dans ladite gorge du fourreau.In addition, for example, the safety disc and the insulating block are provided with means for sealing the safety disc at its periphery, said means for sealing being for example constituted by a peripheral groove which is formed in a sleeve surrounding the insulating block of the element and in which the safety disc rotates, and by an annular seal housed in said groove of the sleeve.

Selon un mode de réalisation, chaque plot d'étanchéité est constitué par un téton de forme correspondante à l'ajour du disque de sécurité à obturer et un joint annulaire disposé à sa base et qui vient s'appliquer en position d'obturation sous le disque de sécurité.According to one embodiment, each sealing pad is constituted by a nipple of corresponding shape to the opening of the safety disc to be sealed and an annular seal disposed at its base and which is applied in the closed position under the security disk.

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

  • la figure 1 montre, à titre d'exemple, un élément de connexion selon l'invention, vu en bout et en position de repos,
  • la figure 2 est une coupe selon II-II de la figure 1,
  • la figure 3 correspond à la coupe de la figure 2 représentant en outre une fiche de connexion destinée à s'accoupler avec l'élément de connexion et après introduction de ladite fiche par un premier mouvement de translation,
  • la figure 4 est une vue qui correspond à la figure 1 après un mouvement de rotation du disque de sécurité, positionnant celui-ci en position de connexion,
  • la figure 5 est une coupe selon la ligne V-V de la figure 4 avec en outre la représentation d'une fiche comme dans la figure 3.
The invention will be well understood and other features will appear on reading the description which follows and which refers to the appended drawings in which:
  • the figure 1 shows, by way of example, a connection element according to the invention, seen at the end and in the rest position,
  • the figure 2 is a section on II-II of the figure 1 ,
  • the figure 3 corresponds to the cut of the figure 2 further representing a connection plug for mating with the connecting element and after insertion of said plug by a first translational movement,
  • the figure 4 is a view that corresponds to the figure 1 after a rotational movement of the safety disk, positioning it in the connection position,
  • the figure 5 is a section along line VV of the figure 4 with in addition the representation of a card as in the figure 3 .

Les dessins représentent un élément de connexion 1 du type socle de prise de courant, ou encore prise mobile d'un prolongateur ou d'un connecteur.The drawings show a connection element 1 of the socket base type, or mobile socket of an extension or a connector.

L'élément 1 est destiné à s'accoupler avec une fiche schématisée en 2 sur les figures 3 et 5.Element 1 is intended to mate with a sheet schematized in 2 on the figures 3 and 5 .

L'élément de connexion 1 comporte plusieurs contacts et dans l'exemple représenté, outre un contact de terre 3a disposé au centre, il est pourvu de quatre contacts 3b-3e périphériques (figures 4 et 5) répartis dans l'exemple représenté, sur une même circonférence et dont un 3c seulement est visible sur la figure 5, lesdits contacts périphériques constituant par exemple un contact neutre et trois contacts de phase.The connection element 1 has several contacts and in the example shown, in addition to a ground contact 3a disposed in the center, it is provided with four peripheral contacts 3b-3e ( Figures 4 and 5 ) distributed in the example shown, on the same circumference and of which only 3c is visible on the figure 5 said peripheral contacts constituting for example a neutral contact and three phase contacts.

Dans cet exemple, les contacts représentés sont des contacts dits en bout aménagés dans des logements d'un bloc isolant 4 et sollicités par des ressorts également disposés dans ledit bloc isolant 4.In this example, the contacts shown are so-called end contacts arranged in housings of an insulating block 4 and biased by springs also arranged in said insulating block 4.

L'élément de connexion 1 est destiné comme déjà dit, à s'accoupler avec une fiche telle que la fiche 2 schématisée sur les figures 3 et 5, qui est munie d'autant de broches de contact (telles que la broche centrale 5a et les broches périphériques 5b et 5c) que l'élément 1 comporte lui-même de contacts.The connection element 1 is intended as already said, to mate with a card such as the sheet 2 schematically on the figures 3 and 5 , which is provided with as many contact pins (such as the central pin 5a and the peripheral pins 5b and 5c) that the element 1 itself comprises contacts.

L'élément de connexion 1 comporte en outre de manière classique, au-dessus du bloc isolant 4, un disque de sécurité 6 rotatif pourvu d'ajours 7a-7e dont le nombre et le positionnement sont choisis de manière, d'une part, à cacher au repos les contacts périphériques 3b-3e de l'élément de connexion 1 (position des figures 1 à 3) et, d'autre part, à se superposer à ceux-ci après rotation du disque de sécurité (position des figures 4 et 5).The connection element 1 further comprises conventionally, above the insulating block 4, a rotary safety disk 6 provided with openings 7a-7e whose number and positioning are chosen so as, on the one hand, to hide at rest the peripheral contacts 3b-3e of the connection element 1 (position of the Figures 1 to 3 ) and, on the other hand, to be superimposed on them after rotation of the safety disk (position of the Figures 4 and 5 ).

La fiche 2 et l'élément de connexion 1 sont en effet pourvus de moyens conjugués pour assurer leur accouplement consistant à introduire selon un premier mouvement de translation les broches 5a-5c de ladite fiche dans les ajours correspondants 7a-7c du disque de sécurité 6, puis à entraîner celui-ci en rotation jusqu'à aligner les broches périphériques de la fiche avec les contacts périphériques de l'élément de connexion (figure 5) et à terminer l'accouplement et ainsi la connexion par un dernier mouvement de translation (non représenté) jusqu'à un verrouillage de l'élément de connexion 1 et de la fiche 2 par des moyens appropriés.The plug 2 and the connecting element 1 are indeed provided with conjugate means to ensure their coupling consisting in introducing in a first translational movement the pins 5a-5c of said plug in the corresponding openings 7a-7c of the safety disc 6 , and then rotating it to align the peripheral pins of the plug with the peripheral contacts of the connection element ( figure 5 ) and terminating the coupling and thus the connection by a last translational movement (not shown) to a locking of the connecting member 1 and the plug 2 by appropriate means.

Afin d'assurer une protection étanche des contacts périphériques de l'élément de connexion qui est généralement sous tension, l'invention préconise d'aménager sous le disque de sécurité, un disque d'étanchéité 8.In order to ensure a leaktight protection of the peripheral contacts of the connection element, which is generally under tension, the invention recommends that a sealing disk 8 be arranged under the safety disc.

Le disque d'étanchéité 8 comporte autant de plots d'étanchéité 9b-9e et d'ajours tels que 16c (figure 5) que le disque de sécurité comporte d'ajours périphériques 7b-7e et qui sont positionnés de la même manière avec un décalage angulaire prévu entre lesdits plots et lesdits ajours du disque d'étanchéité.The sealing disc 8 has as many sealing pads 9b-9e and openings such as 16c ( figure 5 ) that the safety disk comprises peripheral openings 7b-7e and which are positioned in the same way with an angular offset provided between said pads and said openings of the sealing disc.

En outre, le disque d'étanchéité 8 est monté fixe en rotation, mais mobile en translation, tandis qu'il est sollicité vers le disque de sécurité 6 par des moyens élastiques et en l'occurrence ici, par des ressorts tels que 10 (figures 2 et 3) de telle sorte qu'au repos, les plots 9b-9e du disque d'étanchéité 8 viennent obturer les ajours correspondants du disque de sécurité 6, comme le montrent bien les figures 1 et 2.In addition, the sealing disk 8 is mounted fixed in rotation, but mobile in translation, while it is biased towards the safety disk 6 by elastic means and in this case by springs such as 10 ( figures 2 and 3 ) so that at rest, the pads 9b-9e of the sealing disc 8 come to close the corresponding openings of the safety disc 6, as shown by the Figures 1 and 2 .

Pour assurer une obturation étanche, les plots 9b-9e qui se présentent sous la forme de tétons de forme correspondante aux ajours à obturer, sont pourvus à leur base de joints annulaires tels que 11b et 11c (figures 2, 3 et 5) qui restent disposés sous le disque de sécurité 6 et sous lequel ils viennent s'appliquer en position d'obturation.In order to ensure tight sealing, the pads 9b-9e, which are in the form of pins having a shape corresponding to the openings to be closed, are provided at their base with annular seals such as 11b and 11c ( figures 2 , 3 and 5 ) which remain arranged under the security disc 6 and in which they come to apply in the closed position.

Le disque de sécurité est monté rotatif dans un fourreau 12 entourant le bloc isolant 4 et il coopère en outre avec un joint périphérique 13 logé dans une gorge appropriée dudit fourreau 12.The safety disk is rotatably mounted in a sheath 12 surrounding the insulating block 4 and it also cooperates with a peripheral seal 13 housed in a suitable groove of said sheath 12.

Comme le montrent bien en outre les figures 2, 3 et 5, le disque de sécurité 6 et le disque d'étanchéité 8 sont assemblés par une douille 14 autour de laquelle tourne le disque de sécurité 6. Le disque d'étanchéité 8 est monté mobile en translation sur un prolongement tubulaire 15 central du disque de sécurité 6, au moyen d'un ajour central dont il est pourvu et dont la forme est conjuguée de celle dudit prolongement du disque de sécurité.As is also well shown in figures 2 , 3 and 5 , the safety disc 6 and the sealing disc 8 are assembled by a sleeve 14 around which the safety disc 6 rotates. The sealing disc 8 is mounted to move in translation on a central tubular extension 15 of the safety disc. 6, by means of a central opening which it is provided and whose shape is conjugate with that of said extension of the safety disc.

De la sorte, on comprend qu'au repos, le disque d'étanchéité 8 assure, comme déjà dit, une étanchéité vis-à-vis des contacts périphériques 3b-3e des l'élément de connexion (figures 1 et 2).In this way, it is understood that at rest, the sealing disk 8 provides, as already said, a seal vis-à-vis the peripheral contacts 3b-3e of the connection element ( Figures 1 and 2 ).

Au cours de l'accouplement, le premier mouvement de translation de la fiche 2 permet de repousser les plots d'étanchéité 9b-9e à l'encontre de la force des ressorts 10.During the coupling, the first translational movement of the plug 2 makes it possible to push the sealing pads 9b-9e against the force of the springs 10.

Le disque de sécurité 6 peut alors être entraîné en rotation pour venir prendre la position des figures 4 et 5, position dans laquelle les broches périphériques de la fiche, telles que la broche 5c sur la figure 5, se trouvent comme déjà dit alignées avec les contacts périphériques correspondants de l'élément de connexion 1, tels que le contact 3c sur ladite figure 5. Pour réaliser la connexion au cours du dernier mouvement de translation comme précisé ci-avant, les broches périphériques passent au travers du disque d'étanchéité 8 par les ajours dont il est muni tels que l'ajour 16c visible sur la figure 5.The safety disk 6 can then be rotated to take the position of the Figures 4 and 5 , position in which the peripheral pins of the plug, such as pin 5c on the figure 5 , are as already said aligned with the corresponding peripheral contacts of the connection element 1, such that the contact 3c on said figure 5 . To make the connection during the last translational movement as specified above, the peripheral pins pass through the sealing disc 8 by the openings which it is provided such that the openwork 16c visible on the figure 5 .

Les manoeuvres inverses de désaccouplement assurent bien sûr le retour des plots 9b-9e en position d'étanchéité sous l'effet des ressorts 10.The reverse disengagement maneuvers ensure of course the return of the pads 9b-9e in the sealing position under the effect of the springs 10.
