Dans le cas de telles connexions, on accouple de façon amovible des éléments de contact d'une première partie d'enfichage, qui est réalisée sous la forme d'une fiche de faisceau de câbles, à des éléments de contact opposés d'une deuxième partie d'enfichage, qui est réalisée sous la forme d'une fiche contenue dans un boîtier électronique.In the case of such connections, contact elements of a first plug-in part, which is in the form of a cable harness plug, are removably coupled to contact elements opposite one another. plugging part, which is in the form of a plug contained in an electronic box.
Les opérations de connexion ou de déconnexion de tels éléments s'emboîtant peuvent se révéler difficiles à effectuer lorsque les contraintes mécaniques pendant la connexion sont importantes. De plus, une mauvaise connexion risque d'entraîner des faux contacts ou même d'endommager les éléments de contact.The connection or disconnection operations of such interlocking elements can be difficult to perform when the mechanical stresses during connection are important. In addition, a poor connection may result in false contacts or even damage to the contact elements.
Généralement, les boîtiers électroniques sont disposés sous les sièges d'un avion. Cela présente l'inconvénient que le passager, assis sur le siège, peut agir sur le boîtier électronique. De plus, les première et deuxième parties d'enfichage risquent de bouger l'une par rapport à l'autre, ce qui peut entraîner une déconnexion du boîtier électronique. Une telle connexion pose donc des problèmes de fiabilité et de sécurité.Generally, the electronic boxes are arranged under the seats of an aircraft. This has the disadvantage that the passenger, sitting on the seat, can act on the electronic box. In addition, the first and second plugging portions may move relative to each other, which may cause disconnection of the electronic unit. Such a connection therefore poses problems of reliability and security.

En se référant à la
La deuxième partie 3 comporte par exemple, comme éléments de contact (non représentés), une multiplicité de douilles d'enfichage disposées en ligne. Les douilles d'enfichage sont destinées à entourer, en position connectée, des éléments de contact opposés (non représentés) de la première partie 2, par exemple des broches. Un tel connecteur est connu en soi.The
Le connecteur 1 comporte un levier de verrouillage 5 en forme de U. Le levier 5 comporte deux branches latérales 6, sensiblement identiques, reliées ensemble par une entretoise transversale 8. Les branches latérales 6 s'étendent parallèlement l'une à l'autre.The connector 1 comprises a
Les extrémités libres 9 des branches 6 sont fixées de manière pivotante sur des éléments de pivot 11 disposés sur deux faces latérales 12 opposées de la première partie 2. Le levier de verrouillage 5 peut ainsi pivoter par rapport à la première partie 2 autour d'un axe Y sensiblement orthogonal à l'axe X, entre une position de repos (
L'entretoise 8 comporte une partie centrale 13 servant de poignée lors de la manipulation du levier 5, tel que cela sera décrit en détail plus loin.The
Chaque branche 6 présente, en partant de l'entretoise 8, une partie médiane 16 rectiligne disposée de manière à former un angle droit avec la partie d'extrémité 15 correspondante. Au niveau de l'extrémité libre 9, chaque branche 6 comporte une partie terminale 17.Each
Chaque partie terminale 17 est sensiblement plane et disposée dans le même plan que la partie médiane 16. Chaque partie terminale 17 comporte une rainure 18 définissant un chemin de came, la courbure du chemin de came 18 étant dirigée de manière que le chemin de came 18 s'enroule autour du pivot 11. Une extrémité 19 du chemin de came 18, disposée sur un bord de la partie terminale 17, définit une ouverture 20. La distance du chemin de came 18 au pivot 11 diminue de son extrémité 19 vers l'extrémité opposée 24 du chemin de came 18. Une rainure 21 s'étend le long d'une portion 22 du chemin de came 18, une extrémité 23 de la rainure 21 débouchant à l'extrémité 24. De cette manière, le chemin de came 18 définit avec la rainure 21 une languette 25 apte à être déformée élastiquement en réponse à une force de pression exercée sur la languette 25 du chemin de came 18, tel que cela sera décrit en détail plus loin.Each
La deuxième partie 3 comporte, sur chacune de deux faces latérales opposées 30 correspondant aux faces 12, un ergot 31 apte à s'engager dans le chemin de came 18. Les ergots 31 sont disposés de manière que, lorsque la deuxième partie 3 est en butée contre la première partie 2, chaque ergot 31 se trouve au niveau d'une des ouvertures 20.The
Au voisinage de l'extrémité 24, la languette 25 comporte une encoche arrondie qui définit un creux 32 apte à recevoir l'ergot 31 dans la position de verrouillage du levier 5.In the vicinity of the
On va maintenant décrire une opération de connexion des première et deuxième parties 2 et 3, en partant de la position de repos du levier 5, qui est représentée sur la
Dans cette position, un utilisateur approche la deuxième partie 3 de la première partie 2 jusqu'à ce que chaque ergot 31 se trouve en butée contre une ouverture 20 correspondante du levier 5. Cette position est représentée sur les
Lorsque la deuxième partie 3 a été ainsi positionnée par rapport à la première partie 2, l'utilisateur fait pivoter le levier 5 dans le sens de la flèche F (
En partant de cette position, lorsque l'utilisateur continue de faire pivoter le levier 5 dans le sens de la flèche F, chaque ergot 31 coulisse dans le chemin de came 18 correspondant, en direction de l'extrémité 24. Simultanément, la deuxième partie 3, sous l'effet des chemins de came 18 agissant sur les ergots 31, s'engage dans la première partie 2. Lorsque la première partie 2 arrive en butée contre la deuxième partie 3, la languette 25 commence à se déformer par élasticité, du fait de la force de pression exercée par l'ergot 31 sur la languette 25.Starting from this position, when the user continues to rotate the
Lorsque l'ergot 31 arrive au voisinage du creux 32 correspondant, la force de pression exercée par l'ergot 31 sur la languette 25 est maximale, la déformation de la languette 25 étant donc également maximale. Cette position est représentée sur les
Lorsque l'ergot 31 est dans le creux 32, la languette 25 prend une position stable par élasticité, ce qui entraîne la création d'un point dur 33 permettant de maintenir l'ergot 31 dans le creux 32 et d'exercer un effort de compression entre les parties 2 et 3. Cela permet notamment de compenser les intervalles de tolérance de l'accouplement. Dans cette position, les éléments de contact des première et deuxième parties 2 et 3 sont correctement connectés.When the
En outre, dans cette position, la partie centrale 13 de l'entretoise 8 s'étend parallèlement à la face supérieure 34 du boîtier 4, sensiblement parallèlement à l'axe Y. Des parties d'extrémités 15 de l'entretoise 8 s'étendent le long des faces latérales opposées 35 du boîtier, de manière sensiblement perpendiculaire à l'axe X. Les branches 6 s'étendent le long des faces latérales 35, sensiblement parallèlement à l'axe X. Le volume occupé par le levier 5 en position de repos est ainsi minimisé, les parties du levier 5 présentant une faible épaisseur et s'étendant le long du boîtier 4, comme cela est visible sur la
Le levier 5, lorsqu'il est en position de verrouillage, est sensiblement parallèle au boîtier 4. Cela permet au boîtier 4 d'être disposé sous l'assise d'un siège de l'avion de manière sensiblement parallèle au plan de l'assise, c'est-à-dire horizontalement. L'appui de l'assise sur le levier 5 participe au maintien du levier 5 dans sa position horizontale, c'est-à-dire dans sa position de verrouillage, ce qui empêche une déconnexion involontaire du boîtier 4. En outre, un passager ne peut pas accéder au boîtier 4, celui-ci étant disposé sous l'assise de son siège.The
On va maintenant décrire une opération de déconnexion, en partant de la position de verrouillage du levier 5, l'assise du siège ayant été retirée pour rendre le boîtier 4 accessible. Lorsque l'utilisateur agit sur le levier 5 pour lui faire effectuer une rotation autour de l'axe Y dans le sens de la flèche G (
Les chemins de came 18 du levier 5 permettent donc d'assurer une bonne répartition des efforts pendant les opérations de connexion et de déconnexion, ce qui facilite ces opérations pour l'utilisateur. Le levier permet également de définir la profondeur d'insertion et d'assurer le guidage selon l'axe X de la deuxième partie 3 par rapport à la première partie 2, ce qui évite de tordre ou de casser des éléments de contact.The
Bien que l'invention ait été décrite en relation avec un mode de réalisation particulier, il est bien évident qu'elle n'y est nullement limitée et qu'elle comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci entrent dans le cadre de l'invention.Although the invention has been described in connection with a particular embodiment, it is obvious that it is not limited thereto and that it comprises all the technical equivalents of the means described and their combinations if they are within the scope of the invention.
