Demande correspondante Corresponding request
La présente demande revendique la priorité de la demande antérieure N° PCT/IB2018/052391 , déposée le 6 avril 2018 au nom de Fischer Connectors Holding SA, le contenu de cette demande antérieure étant incorporé par référence dans son entièreté dans la présente demande de brevet.  The present application claims the priority of the earlier application No. PCT / IB2018 / 052391, filed on April 6, 2018 in the name of Fischer Connectors Holding SA, the contents of this prior application being incorporated by reference in its entirety in the present patent application. .
Domaine de l’invention Field of the invention
La présente invention concerne les connecteurs, en particulier les connecteurs électriques multipolaires, utilisés par exemple dans le domaine du câblage électrique. Par exemple, les connecteurs concernés sont utilisés pour/dans des domaines nécessitant à la fois de la fiabilité et de la flexibilité, tels que les applications de type wearable, par exemple les tenues ou équipements de personnes évoluant dans des environnements difficiles (travailleurs, service de secours, soldats et forces de sécurité, etc... ) ou toute autre utilisation similaire.  The present invention relates to connectors, in particular multipole electrical connectors, used for example in the field of electrical wiring. For example, the relevant connectors are used for / in areas requiring both reliability and flexibility, such as wearable-type applications, such as outfits or equipment of people operating in harsh environments (workers, service providers). rescue, soldiers and security forces, etc ...) or any other similar use.
Etat de la technique State of the art
Dans la plupart des cas, l’utilisation d’un connecteur multipolaire nécessite que les deux composants principaux du connecteur (p.ex. un composant contenant des contacts mâles par exemple une fiche et un composant avec des contacts femelles par exemple une embase) soient connectés l’un par rapport à l’autre selon une orientation angulaire spécifique et prédéterminée. Cette contrainte peut être réalisée par des formes particulières des composants ne permettant qu'une connexion selon une position relative prédéterminée, ou d'autres moyens techniques équivalents (comme des constructions asymétriques, des éléments à emboîtement etc.).  In most cases, the use of a multipolar connector requires that the two main components of the connector (eg a component containing male contacts for example a plug and a component with female contacts, for example a socket) are connected to each other in a specific and predetermined angular orientation. This constraint can be achieved by particular shapes of the components allowing only a connection according to a predetermined relative position, or other equivalent technical means (such as asymmetrical constructions, interlocking elements, etc.).
Toutefois, le fait de devoir aligner un composant par rapport à l’autre, préalablement à la connexion, constitue un désagrément pour l'utilisateur. Ce désagrément est particulièrement notable si les composants du connecteur ne sont pas visibles par l'utilisateur au moment de la connexion (par exemple par manque de lumière, ou dans une position cachée à la vue), ou encore lorsque la connexion doit se faire rapidement. Il existe donc un besoin de pouvoir supprimer ce désagrément. However, the fact of having to align one component with respect to the other, prior to the connection, is an inconvenience for the user. This inconvenience is particularly noticeable if the components of the connector are not visible to the user at the time of connection (for example due to lack of light, or in a position hidden from view), or when the connection must be made quickly. . There is therefore a need to be able to remove this inconvenience.
La demande internationale WO 2017/072620 décrit un connecteur multipolaire visant à surmonter ces problèmes, le contenu de cette demande antérieure étant incorporé par référence dans la présente demande. International application WO 2017/072620 describes a multipolar connector to overcome these problems, the content of this prior application being incorporated by reference in the present application.
Le connecteur décrit dans cette demande antérieure comprend une embase de forme sensiblement cylindrique et une fiche, connectable à l’embase de manière amovible ou détachable, dans laquelle fiche sont disposés une pluralité de contacts. L’embase comporte une face conductrice en forme de disque sur ou dans laquelle est disposée au moins une piste conductrice formant au moins un arc de cercle dont le centre se confond sensiblement avec le centre de la face conductrice, ladite piste étant en outre disposée de manière à réaliser un couplage électrique mécanique avec l’un des dits contacts de la fiche lorsque la fiche et l'embase sont connectées. The connector described in this prior application comprises a base of substantially cylindrical shape and a plug connectable to the base removably or releasably, in which plug are arranged a plurality of contacts. The base comprises a disc-shaped conductive surface on or in which is disposed at least one conductive track forming at least one circular arc whose center substantially coincides with the center of the conductive face, said track being further disposed of to achieve a mechanical electrical coupling with one of said contacts of the plug when the plug and the base are connected.
Dans la configuration particulière qui ne comporte qu’une seule piste circulaire, le centre de la face de l’embase est un disque conducteur, qui est disposé de manière à réaliser un couplage électrique avec un contact de la fiche disposé au centre de cette dernière. In the particular configuration which has only one circular track, the center of the face of the base is a conductive disk, which is arranged to perform an electrical coupling with a contact of the plug disposed in the center of the latter .
De préférence le connecteur décrit comporte plusieurs pistes conductrices circulaires qui sont disposées de manière concentrique. En général, le nombre de pistes est égal au nombre de contacts mais dans des modes d'exécution, leur nombre peut être différent. Cette construction et ses différents modes d'exécution sont applicables au connecteur selon la présente invention. Preferably the connector described has a plurality of circular conductive tracks which are arranged concentrically. In general, the number of tracks is equal to the number of contacts but in execution modes, their number may be different. This construction and its various embodiments are applicable to the connector according to the present invention.

De façon générale, le connecteur selon la présente invention est similaire à celui décrit dans la demande WO 2017/072620 en ce qu'il comprend une embase et une fiche, la fiche se connectant de façon détachable à l'embase comme exposé dans cette demande antérieure, incorporée par référence dans la présente demande. In general, the connector according to the present invention is similar to that described in application WO 2017/072620 in that it comprises a base and a plug, the plug connecting detachably to the base as described in this application prior art, incorporated by reference in the present application.
Dans un mode d'exécution, l'invention concerne un module de verrouillage étanche 20 d'une fiche sur une embase 3. In one embodiment, the invention relates to a sealed locking module 20 of a plug on a base 3.
Le module 20 de verrouillage pour connecter une fiche à une embase 3 présente une étanchéité aux fluides de manière à garantir la possibilité de connexion à des températures largement en-dessous de 0°C en évitant le gel et la présence de glace dans le système ou d'autres éléments indésirables. The locking module 20 for connecting a plug to a base 3 has a fluid tightness so as to guarantee the possibility of connection at temperatures well below 0 ° C., avoiding freezing and the presence of ice in the system. other undesirable elements.
Comme illustré dans les figures, le module 20 comprend notamment des ogives 21 (il y en a six dans la version illustrée, néanmoins on peut imaginer toutes les variantes possibles en matière de nombre d’ogives, mais de préférence il y en a au moins trois réparties de façon symétrique) assemblées dans une membrane souple 22 (de forme annulaire dans l’exemple, on peut aussi imaginer une version sous forme de bande qui serait ensuite roulée de manière à constituer un cylindre/anneau ou une autre manière de procéder équivalente). As illustrated in the figures, the module 20 comprises in particular warheads 21 (there are six in the illustrated version, nevertheless one can imagine all possible variants in terms of number of warheads, but preferably there are at least three symmetrically distributed) assembled in a flexible membrane 22 (ring-shaped in the example, one can also imagine a version in the form of a strip which would then be rolled so as to form a cylinder / ring or other equivalent way of proceeding ).
La membrane souple 22 peut être réalisée par tout type de moyen (injection, étampage, poinçonnage...) et dans tous types de matières synthétiques de manière à résister aux agents chimiques, p.ex. ou supporter d'autres contraintes, et de réaliser l'étanchéité souhaitée selon les principes de la présente invention. La membrane souple peut aussi avoir une autre forme que la forme annulaire illustrée à titre d'exemple. Elle peut avoir une forme ovale, carrée ou autre en fonction des circonstances et de la forme des parties du connecteur. The flexible membrane 22 may be made by any type of means (injection, stamping, punching, etc.) and in all types of synthetic material so as to withstand chemical agents, eg, or withstand other constraints, and achieve the desired seal according to the principles of the present invention. The flexible membrane may also have a shape other than the annular form illustrated by way of example. It may have an oval, square or other shape depending on the circumstances and the shape of the parts of the connector.
Les ogives 21 peuvent avoir la forme illustrée dans les figures ou une autre forme. Par exemple, elles peuvent avoir une forme de bille, une forme ovale une autre forme équivalente. The warheads 21 may have the form illustrated in the figures or another form. For example, they may have a ball shape, an oval shape another equivalent shape.
Le sous-ensemble 23 (voir figure 1) ainsi constitué est positionné sur une bague 24 de la fiche (voir figures 2 à 5). The subassembly 23 (see FIG. 1) thus constituted is positioned on a ring 24 of the plug (see FIGS. 2 to 5).
Le sous-ensemble 23 monté sur la bague 24 est ensuite assemblé dans un ressort de verrouillage 25 par recouvrement qui permet de garantir la force d’appui sur le sous- ensemble 23. Le ressort de verrouillage 25 peut être en toute matière appropriée, par exemple métal ou matière synthétique. Le ressort comprend de préférence une partie fixe 26 et des parties mobiles 27 qui donnent du jeu aux ogives 21 et permettent donc la connexion et la déconnexion de la bague 24 (respectivement de la fiche) sur une embase 3 par exemple. La force de la connexion entre la fiche et l'embase est notamment déterminée par les parties mobiles 27 qui fonctionnent comme des ressorts appuyant sur les ogives 21. Ces parties mobiles 27 peuvent être dimensionnées de façon à calibrer la force qu'elles appliquent sur les ogives et par conséquent la force nécessaire pour la connexion et la déconnexion de la fiche sur l'embase 3. The subassembly 23 mounted on the ring 24 is then assembled in an overlapping locking spring 25 which makes it possible to guarantee the bearing force on the subassembly 23. The locking spring 25 may be of any suitable material, for example example metal or synthetic material. The spring preferably comprises a fixed portion 26 and moving parts 27 which give play to the warheads 21 and thus allow the connection and disconnection of the ring 24 (respectively of the plug) on a base 3 for example. The force of the connection between the plug and the base is determined in particular by the moving parts 27 which function as springs pressing on the warheads 21. These movable parts 27 can be dimensioned so as to calibrate the force they apply to them. warheads and therefore the force required for connection and disconnection of the plug on the base 3.
Par exemple, les parties mobiles 27 peuvent être plus ou moins longues ou plus ou moins courtes, plus ou moins épaisses, avoir une forme ou découpe particulière, ou être précontraintes etc. afin de déterminer leur force d'appui. Tous ces paramètres sont adaptables en fonction des circonstances et de la construction désirée. For example, the moving parts 27 may be more or less long or more or less short, more or less thick, have a particular shape or cut, or be prestressed and so on. to determine their support strength. All these parameters are adaptable according to the circumstances and the desired construction.
Ainsi, les dimensions et caractéristiques du ressort 25 (en particulier des parties mobiles 27) permettent, d'une part, de définir la force d’appui sur les ogives 21 et donc la force de verrouillage du module de verrouillage étanche 20 et d'autre part, la force de compression du ressort 25 (soit des parties mobiles 27) va également comprimer la membrane souple 22 par l'intermédiaire des ogives 21 et la déformation de la membrane 22 par compression va notamment l'étendre dans le sens perpendiculaire à celui de la force de compression ce qui aura une conséquence bénéfique sur l'étanchéité de la bague 24. Plus précisément, la membrane 22 se déforme en compression dans le sens parallèle à celui de la force de compression du ressort 25 et en expansion dans le sens perpendiculaire à celui de la force de compression ce qui réalise l'étanchéité souhaitée autour des ogives 21 et dans la bague 24. Thus, the dimensions and characteristics of the spring 25 (in particular of the moving parts 27) make it possible, on the one hand, to define the pressing force on the warheads 21 and thus the locking force of the leaktight locking module 20 and of on the other hand, the compressive force of the spring 25 (ie moving parts 27) will also compress the flexible membrane 22 via the warheads 21 and the deformation of the compression membrane 22 will in particular extend in the direction perpendicular to that of the compression force which will have a beneficial effect on the sealing of the ring 24. More specifically, the membrane 22 deforms in compression in the direction parallel to that of the compression force of the spring 25 and expanding in the direction perpendicular to that of the compressive force which achieves the desired sealing around the ribs 21 and in the ring 24.
Des joints 30, 31 , 32, de type O-ring par exemple, peuvent être disposés à des endroits appropriés de la bague 24 pour maintenir l'étanchéité. Seals 30, 31, 32, O-ring type for example, may be arranged at appropriate locations of the ring 24 to maintain the seal.
L’ensemble ainsi constitué peut se connecter sur une contre-pièce, par exemple une embase 3, présentant une gorge 28 dont la géométrie contribue à définir la force de verrouillage, ladite gorge recevant les ogives 21 comme on le voit dans la figure 6. The assembly thus formed can be connected to a counter-piece, for example a base 3, having a groove 28 whose geometry contributes to defining the locking force, said groove receiving the ribs 21 as seen in FIG.
L'ensemble monté d'un module 20 sur une embase 3 est illustré à titre d'exemple en figure 6 et le module est typiquement une partie de la fiche qui sera connectée à l'embase selon les principes exposés dans WO 2017/072620. La figure 7 illustre un exemple d'une telle embase 3 vue de dessus, avec des pistes circulaires et concentriques 33. The assembled assembly of a module 20 on a base 3 is illustrated by way of example in FIG. 6 and the module is typically a part of the plug which will be connected to the base according to the principles set forth in WO 2017/072620. FIG. 7 illustrates an example of such a base 3 seen from above, with circular and concentric tracks 33.
Selon les modes de réalisation illustrés dans la présente demande, la fiche 2 comporte plusieurs contacts et l'embase plusieurs pistes 33, par exemple de façon similaire à ce qui est décrit dans WO 2017/072620. According to the embodiments illustrated in the present application, the plug 2 has several contacts and the base several tracks 33, for example in a manner similar to that described in WO 2017/072620.
La figure 8 illustre une fiche 2 et une embase 3 connectés selon principes de la présente invention. La fiche 2 comprend notamment un module 20 tel que décrit en référence aux figures précédentes avec sa bague et ses ogives 21. La fiche 2 comprend également des contacts qui sont en contact avec les pistes 33 de l'embase, selon les principes de WO 2017/072620. Figure 8 illustrates a plug 2 and a base 3 connected according to the principles of the present invention. The plug 2 comprises in particular a module 20 as described with reference to the previous figures with its ring and its warheads 21. The plug 2 also includes contacts that are in contact with the tracks 33 of the base, according to the principles of WO 2017 / 072620.
Il va de soi que l’invention ne se limite pas à cette configuration. Elle couvre également les connecteurs comportant au moins un contact. It goes without saying that the invention is not limited to this configuration. It also covers connectors having at least one contact.
De même, les dimensions du connecteur selon l’invention peuvent être quelconques. Le connecteur selon l’invention a la particularité de ne pas nécessiter d’orientation préalable de la fiche (p.ex. un élément câblé) par rapport à l’embase 3 (p.ex. un élément de boîtier d’appareil, ou sur un produit comme un habit 4 ou autre). Cet avantage résulte de la géométrie cylindrique/circulaire de l’embase et de sa face conductrice (voir p.ex. la figure 1 de WO 2017/072620). Une fois connectés, la rotation relative entre l’embase 3 et la fiche 2 peut être libre ou bloquée par l’intermédiaire d’un système approprié, par exemple de type bi-stable pour citer un exemple non-limitatif, par exemple un verrouillage par pression latérale et déverrouillage par pression axiale un système de crans ou encore un système actionnable manuellement. Un blocage entre la fiche 2 et l'embase 3 peut également être mis en œuvre pour bloquer le "désenfichage" de la fiche 2. Un exemple de réalisation est le système dit "push-pull". Le système de blocage peut aussi être mis en œuvre pour une utilisation combinée, c'est-à-dire à la fois pour limiter ou bloquer une rotation relative, et en plus bloquer un désenfichage. Similarly, the dimensions of the connector according to the invention may be arbitrary. The connector according to the invention has the particularity of not requiring prior orientation of the plug (eg a wired element) with respect to the base 3 (eg a device housing element, or on a product like a dress 4 or other). This advantage results from the cylindrical / circular geometry of the base and its conductive face (see eg Figure 1 of WO 2017/072620). Once connected, the relative rotation between the base 3 and the plug 2 can be free or blocked by means of a suitable system, for example bi-stable type to cite a non-limiting example, for example a lock by lateral pressure and unlocking by axial pressure a system of notches or a manually operable system. A block between the plug 2 and the base 3 can also be implemented to block the "unplugging" of the plug 2. An exemplary embodiment is the so-called "push-pull" system. The locking system can also be implemented for a combined use, that is to say both to limit or block a relative rotation, and in addition to block unplugging.
Une orientation peut néanmoins être donnée et limiter les possibilités d’enfichage à un nombre fini de positions angulaires différentes (p.ex. quatre positions séparées de 90° ou 12 positions séparées de 30°) comme décrit sur la Figure 2 de WO 2017/072620. La figure 10 illustre une embase 3 avec des pistes 33 et un exemple de moyens de blocage entre l'embase 3 et la fiche 2. Dans cet exemple, ces moyens comprennent des logements 14 dans lesquels les ogives ou billes 21 de la fiche 2 (voir figure 8) peuvent se loger pour bloquer ou limiter la rotation relative entre la fiche 2 et l'embase 3 et/ou empêcher un désenfichage (par exemple en dessous d'une certaine force de traction). Le nombre de logements 14 peut par exemple être un multiple du nombre d'ogives 21. An orientation can nevertheless be given and limit the possibilities of insertion to a finite number of different angular positions (eg four positions separated by 90 ° or 12 positions separated by 30 °) as described in Figure 2 of WO 2017 / 072620. FIG. 10 illustrates a base 3 with tracks 33 and an example of locking means between the base 3 and the plug 2. In this example, these means comprise housings 14 in which the ribs or balls 21 of the plug 2 (FIG. see Figure 8) can be housed to block or limit the relative rotation between the plug 2 and the base 3 and / or prevent unplugging (for example below a certain traction force). The number of housing 14 may for example be a multiple of the number of warheads 21.
La figure 9 illustre un exemple d'utilisation d'un connecteur selon la présente invention: dans cet exemple non-limitatif, l'embase 3 est fixée sur un gilet 4 et la fiche 2 est prête à être connectée à l'embase 3 pour arriver à la configuration de la figure 8. FIG. 9 illustrates an example of use of a connector according to the present invention: in this non-limiting example, the base 3 is fixed on a vest 4 and the plug 2 is ready to be connected to the base 3 for arrive at the configuration of Figure 8.
L'invention n'est bien entendue pas limitée aux modes d'exécution et exemples décrits dans la présente demande à titre illustratif et non-limitatif. Des variations sont possibles dans le cadre de la protection conférée et revendiquée, notamment en faisant appel à des moyens équivalents. Les modes d'exécution peuvent aussi être combinés entre eux et des caractéristiques techniques de l'un des modes peuvent être utilisées dans un autre mode. Par exemple, dans des modes d'exécution, la construction de la fiche et de l'embase est inversée: c'est-à-dire que les contacts 35 peuvent être sur l'embase 3 et les pistes 33 sur la fiche 2. Dans un tel cas, on retrouve la construction décrite dans la présente demande mais inversée, à savoir que des éléments de la fiche 2 (notamment illustrés dans les figures 1 à 5) sont placés sur/dans l'embase 3 et des éléments de l'embase 3 (notamment les pistes 33, logements 14, figure 7) sont placés sur/dans la fiche 2 et les principes de la présente invention tels que décrits dans la présente ne changent pas et s'appliquent de façon correspondante à ces modes d'exécution. The invention is of course not limited to the embodiments and examples described in the present application for illustrative and non-limiting. Variations are possible in the context of the protection conferred and claimed, in particular by equivalent means. The execution modes can also be combined with one another and technical characteristics of one of the modes can be used in another mode. For example, in embodiments, the construction of the plug and the base is reversed: that is to say that the contacts 35 can be on the base 3 and the tracks 33 on the plug 2. In such a case, we find the construction described in the present application but reversed, namely that elements of the plug 2 (in particular illustrated in Figures 1 to 5) are placed on / in the base 3 and elements of the base 3 (in particular tracks 33, housings 14, FIG. 7) are placed on / in plug 2 and the principles of the present invention as described herein do not change and apply correspondingly to these modes of operation. 'execution.
D'autres variantes sont bien entendu envisageables dans le cadre de la présente invention. Other variants are of course conceivable in the context of the present invention.
