Abstract
Description
L'invention concerne un dispositif de connexion électrique étanche comportant deux éléments de connexion conjugués.The invention relates to a sealed electrical connection device comprising two conjugated connection elements.
Il est connu de réaliser des dispositifs de connexion électrique comportant deux éléments de connexion conjugués, dont l'un comporte un carter extérieur, et qui sont munis chacun de contacts électriques destinés à coopérer entre eux dans une position de connexion, après accouplement desdits éléments obtenu par un premier mouvement relatif de translation, suivi d'une rotation et d'une seconde translation, les éléments de connexion étant à la fin de ladite rotation dans une position intermédiaire de repos dans laquelle lesdits éléments sont retenus temporairement entre eux, sans connexion des contacts, tandis que la connexion n'est établie entre les contacts des deux éléments de connexion qu'à la fin de la seconde translation déterminant ladite position de connexion.It is known to provide electrical connection devices comprising two conjugated connection elements, one of which comprises an outer casing, and which are each provided with electrical contacts intended to cooperate with each other in a connection position, after coupling of said elements obtained. by a first relative translational movement, followed by a rotation and a second translation, the connection elements being at the end of said rotation in an intermediate position of rest in which said elements are held temporarily between them, without connection of contacts, while the connection is established between the contacts of the two connecting elements at the end of the second translation determining said connection position.
Un tel dispositif est notamment décrit dans le document
Par exemple, l'un des éléments constitue un socle de prise de courant, ou encore la prise mobile d'un prolongateur ou d'un connecteur, tandis que l'autre élément peut être un socle de connecteur fixe ou muni d'une poignée pour former une fiche.For example, one of the elements constitutes a base socket, or the mobile socket of an extension or a connector, while the other element can be a fixed connector base or provided with a handle to form a form.
Il est souvent important, voire obligatoire dans certains lieux ou milieux, de pouvoir assurer une étanchéité d'un tel dispositif.It is often important, even mandatory in certain places or environments, to be able to seal such a device.
On a déjà imaginé des moyens pour assurer une étanchéité de l'élément sous tension en l'absence d'accouplement en prévoyant par exemple un couvercle.Means have already been devised for sealing the element under tension in the absence of coupling, for example by providing a cover.
Toutefois, il faut aussi pouvoir assurer une étanchéité du dispositif aussi bien dans la position intermédiaire de repos que dans la position de connexion.However, it must also be able to ensure a seal of the device both in the intermediate position of rest as in the connection position.
En vue d'assurer une telle étanchéité, le document précité
Cependant, un tel dispositif ne donne pas satisfaction et les inventeurs ont dû imaginer et trouver d'autres moyens.However, such a device is unsatisfactory and the inventors had to imagine and find other ways.
Par ailleurs, il est également connu du document
Toutefois, un tel système est inadapté pour réaliser un dispositif de connexion tel que décrit précédemment, notamment pour des problèmes de guidage des éléments de connexion entre eux, l'impossibilité d'une rotation desdits éléments de connexion l'un sur l'autre, l'impossibilité d'adjoindre un disque de sécurité, ...However, such a system is unsuitable for producing a connection device as described above, in particular for problems of guiding the connection elements with each other, the impossibility of a rotation of said connection elements on one another, the impossibility of adding a security disk, ...
C'est pourquoi, l'invention propose un dispositif du type précité à propos du document
Avantageusement, les moyens de guidage comportent un fourreau solidaire de l'anneau du joint, qui vient coulisser sur une partie fixe de l'élément de connexion pourvu dudit joint et dans ce cas par exemple, le fourreau comporte en outre un moyen élastique de rappel en position initiale d'extension du joint.Advantageously, the guide means comprise a sheath integral with the ring of the seal, which is slidable on a fixed part of the connecting element provided with said seal and in this case for example, the sheath further comprises an elastic means of recall in initial position of extension of the joint.
De préférence, la surface du carter destinée à coopérer avec la surface frontale du joint, est tronconique et striée.Preferably, the surface of the housing intended to cooperate with the front surface of the seal, is frustoconical and striated.
Selon un mode de réalisation, le joint est plissé en accordéon, mais selon un autre mode de réalisation particulièrement avantageux, le joint est aménagé pour subir un simple repliement vers l'intérieur au cours des manoeuvres de connexion.According to one embodiment, the seal is folded accordion, but according to another particularly advantageous embodiment, the seal is arranged to undergo a simple folding inward during the connection maneuvers.
Dans ce dernier cas, par exemple, le joint présente une partie cylindrique circulaire à son extrémité fixée à l'élément dé connexion correspondant, prolongée par une partie tronconique qui se termine par la surface frontale annulaire de butée formant un épaulement.In the latter case, for example, the seal has a circular cylindrical portion at its end fixed to the corresponding connection member, extended by a frustoconical portion which terminates in the annular end face abutment forming a shoulder.
Selon un mode de réalisation, les moyens conjugués de guidage en rotation et de retenue en position intermédiaire de repos des éléments de connexion sont aménagés, d'une part, sur l'anneau d'extrémité du joint et, d'autre part, à l'extrémité du carter, ledit anneau s'étendant au-delà de la surface frontale annulaire de butée du joint et étant dimensionné pour venir au moins en partie à l'intérieur dudit carter.According to one embodiment, the conjugate means for guiding in rotation and retaining in the intermediate rest position of the connection elements are arranged, on the one hand, on the end ring of the seal and, on the other hand, at the end of the housing, said ring extending beyond the annular abutment end surface of the seal and being dimensioned to come at least partly inside said housing.
Par exemple, lesdits moyens conjugués de guidage en rotation et de retenue en position intermédiaire sont de type à ergots et rampes, lesdites rampes présentant une pente qui accentue la pression de la surface frontale annulaire de butée du joint sur la surface conjuguée du carter.For example, said conjugate means of rotation guide and intermediate position retaining are of type pins and ramps, said ramps having a slope which increases the pressure of the annular end surface of the seal abutment on the conjugate surface of the housing.
L'invention sera bien comprise à la lecture de la description qui va suivre et qui se réfère aux dessins annexés dans lesquels :
- les
figures 1 et 2 montrent en perspective deux éléments constitutifs d'un mode de réalisation d'un dispositif de connexion selon l'invention, sous la forme ici, non limitative, d'un prolongateur comportant une prise mobile de prolongateur (figure 1 ) et une fiche (figure 2 ), - la
figure 3 montre en coupe longitudinale le dispositif desfigures 1 et 2 avant accouplement, - la
figure 4 est une coupe correspondante de lafigure 3 , mais dans laquelle les deux éléments sont représentés en partie accouplés, en position intermédiaire de repos, - la
figure 5 est une coupe correspondante desfigures 3 et 4 , mais dans laquelle les deux éléments sont représentés en position de connexion.
- the
Figures 1 and 2 show in perspective two constituent elements of an embodiment of a connection device according to the invention, in the form here, not limiting, of an extension comprising a mobile extension connector (figure 1 ) and a form (figure 2 ) - the
figure 3 shows in longitudinal section the device ofFigures 1 and 2 before coupling, - the
figure 4 is a corresponding section of thefigure 3 , but in which the two elements are represented in part coupled, in an intermediate rest position, - the
figure 5 is a corresponding section ofFigures 3 and 4 but in which the two elements are represented in the connection position.
Si les dessins représentent à titre d'exemple un prolongateur, il pourrait bien sûr s'agir, comme déjà dit ci-avant, d'une prise de courant avec socle, ou d'un connecteur.If the drawings represent an example of an extension, it could of course be, as already said above, a socket with base, or a connector.
Les dessins montrent une prise mobile 1 de prolongateur (
La prise 1 et la fiche 2 sont pourvues chacune de contacts sous forme par exemple ici, de contacts en bout, tels que le contact 3 schématisé sur les dessins, pour la prise, et de broches, telles que 4a, 4b, pour la fiche.The
Il est clair bien entendu que le nombre de contacts est quelconque, un contact central de terre étant en outre généralement prévu, mais ces aspects sont indépendants de la présente invention.It is clear, of course, that the number of contacts is arbitrary, a central ground contact being furthermore generally provided, but these aspects are independent of the present invention.
Les contacts 3 pourraient être de plus des alvéoles plutôt que des contacts en bout afin de former des contacts dits à broches et alvéoles, l'invention étant également indépendante de la nature des contacts.The
Dans le mode de réalisation représenté, on a en outre prévu un disque rotatif 5, dit de sécurité.In the embodiment shown, there is further provided a rotating
Les contacts de la prise sont alimentés en courant par des câbles électriques schématisés en 6a, 6b.The contacts of the socket are supplied with current by electric cables shown schematically in 6a, 6b.
Les broches de contact 4a, 4b de la fiche sont également raccordées à des câbles électriques 7a, 7b, eux-mêmes destinés à être raccordés à un appareil ou un dispositif à alimenter en courant.The
Les contacts 3 de la prise sont montés dans un bloc isolant 8 entouré ici en partie d'un fourreau 9 monté libre en translation et muni d'un moyen élastique de rappel 10, sous forme dans cet exemple d'un ressort hélicoïdal.The
Le fourreau 9 se termine par une partie annulaire formant un anneau 11 qui, dans cet exemple, entoure dans au moins l'état initial au moins en partie le disque 5 de sécurité.The
Comme le montrent bien en outre les dessins, la fiche 2 présente un carter extérieur 12 qui entoure les broches 4a, 4b tandis que la prise mobile 1 est pourvue d'un joint 13 souple tubulaire extérieur fixé par une extrémité à une partie de ladite prise et à son autre extrémité à l'anneau 11. Dans cet exemple avantageux, le joint 13 présente une partie cylindrique circulaire 13a du côté fixé à la prise mobile 1, qui est prolongée par une partie tronconique 13b.As further shown in the drawings, the
En position de repos (
En outre, dans cet exemple, la surface 15 du carter 12 est sensiblement tronconique et striée pour un meilleur contact.In addition, in this example, the
Les matières utilisées pour le carter et le joint et/ou l'état des surfaces 14 et 15 sont choisies pour permettre un certain glissement desdites surfaces l'une sur l'autre au cours d'un mouvement rotatif comme il sera précisé ci-après.The materials used for the casing and the seal and / or the state of the
Par ailleurs, comme le montrent plus particulièrement les
Ces moyens se présentent dans l'exemple représenté sous la forme ici d'ergots, tels que l'ergot 16 visible sur les
Le fonctionnement est désormais simple à comprendre.Operation is now easy to understand.
En partant de la
Les broches 4a, 4b sont introduites dans des ajours aménagés à cet effet dans le disque de sécurité 5, le positionnement angulaire et le premier mouvement translatif étant guidés par les ergots 16 et les rampes 17a, 17b des éléments, tandis que les surfaces 14 et 15, respectivement du joint 13 et du carter 12, entrent en contact, c'est-à-dire en butée l'une contre l'autre.The
Les rampes 17a et 17b bien visibles sur la
Dans cette position de la
En outre, toujours dans la position de la
En effet, l'étanchéité peut résulter du simple contact des surfaces 14 et 15, lesdites surfaces pouvant présenter diverses formes pour améliorer ladite étanchéité.Indeed, the seal may result from the simple contact of the
Les rampes 17a, 17b peuvent de plus présenter une certaine pente pour permettre un léger serrage.
Il suffit ensuite pour passer de la position de repos de la
Cette translation entraîne alors un repliement vers l'intérieur du joint 13 et donc un raccourcissement longitudinal, comme le montre bien la
On comprend et on constate que la partie tronconique 13b se replie par l'intérieur sur elle-même et vers la partie cylindrique 13a.It is understood and found that the
Des moyens de retenue (non représentés plus spécialement) dans cette position de connexion de la
On comprend alors que depuis au moins la position intermédiaire de repos des éléments après leur rotation et jusqu'à leur position de connexion, on assure une étanchéité entre la prise 1 et la fiche 2 au moyen du joint 13, joint qui reprend sa position initiale montrée à la
De nombreuses variantes peuvent évidemment être imaginées, sans sortir du cadre de l'invention, concernant les moyens annexes tels que, par exemple, les contacts, les moyens de guidage, l'absence ou non du disque de sécurité, ou le rajout d'un autre disque.Many variants can obviously be imagined, without departing from the scope of the invention, relating to additional means such as, for example, the contacts, the guide means, the absence or absence of the security disk, or the addition of another disc.
Toutefois, il est clair aussi que le joint 13 peut être envisagé selon d'autres modes de réalisation que celui représenté. Ledit joint doit être souple pour pouvoir subir un plissement entraînant un raccourcissement longitudinal.However, it is also clear that the
En effet, selon un autre mode de réalisation, le joint peut, par exemple, être un joint à soufflet, du type plissé en accordéon qui peut subir au cours de la dernière translation un plissement et un raccourcissement par compression dudit joint.Indeed, according to another embodiment, the seal may, for example, be a bellows seal, the pleated accordion type which can undergo during the last translation a folding and a shortening by compression of said seal.
Le mode de réalisation représenté, par rapport à un joint plié en accordéon, est moins encombrant et permet de réduire le diamètre de l'appareil tout en limitant la longueur du fait que le joint de ce mode de réalisation peut travailler (repliement et dépliement) dans un volume cylindrique moins long et moins large. Par ailleurs, une telle forme permet d'éviter l'accumulation de saletés qui est inévitable avec une forme en accordéon.The embodiment shown, with respect to an accordion-folded seal, is less cumbersome and makes it possible to reduce the diameter of the apparatus while limiting the length of the fact that the seal of this embodiment can work (folding and unfolding) in a cylindrical volume shorter and less wide. Moreover, such a shape avoids the accumulation of dirt that is inevitable with an accordion shape.
Enfin, si un plissement en accordéon permet d'obtenir un joint plus élastique en raison des plis de la matière, l'utilisation d'un ressort permet de toutes façons d'utiliser un joint n'ayant aucune résistance élastique.Finally, if a folding accordion makes it possible to obtain a more elastic seal because of the folds of the material, the use of a spring makes it possible anyway to use a seal having no elastic resistance.
Le mot plissement doit donc être compris dans son sens le plus général puisque le joint peut se déformer selon un ou plusieurs plis.The word wrinkling must be understood in its most general sense since the seal can be deformed in one or more folds.
