Abstract

The connector has male and female parts locked together using standard techniques. Both parts are cylindrical, the fibres (4,14) being held by internal shoulders (5,15) at their entry points. The shoulders define one end of a wide channel (11,21) allowing the fibres to bend during connection. The male connector (1) has a fixed insert (7) at its mating end in which is recessed one optical fibre. The female connector has an insert (17) in which its fibre can slide, the insert itself sliding within its cylinder. As the two parts are coupled the sliding insert is forced back against a spring (23) its optical fibre entering the insert in the male half of the connector.

Description

La présente invention a pour objet un dispositif de connexion pour fibres optiques, pour lesquelles la difficulté à résoudre est de réussir à raccorder des fibres qui sont très fragiles et qui ont des diamètres de l'ordre de 50 à 1000 microns et cela avec un minimum de pertes ou affaiblissement du signal optique au niveau de la connexion. The present invention relates to a connection device for optical fibers, for which the difficulty to solve is to succeed in connecting fibers which are very fragile and which have diameters of the order of 50 to 1000 microns and this with a minimum. loss or weakening of the optical signal at the connection.

Le dispositif selon la présente invention comporte deux manchons creux l'un constituant le manchon mâle et l'autre le manchon femelle, chacun d'eux comportant un moyen de serrage immobilisant la fibre à une certaine distance de son extrémité, et un guide cylindrique creux, traversé par un alésage d'un diamètre très légèrement supérieur à celui de la fibre, ledit alésage débouchant à chaque extrémité dans une cuvette tronconique, le guide du manchon mâle étant fixe par rapport à son manchon et faisant saillie hors de celui-ci, le guide du man chon femelle étant mobile à l'encontre d'un ressort de façon à pouvoir pénétrer à l'intérieur de son manchon en coulissant par rapport à la fibre optique, la course dumanchon mobile étant très légèrement supérieure à la distance séparant les deux fibres de façon que lorsque les deux manchons sont assem manchon bles l'un contre l'autre la fibre duïfemèlle sorte de son guide au fur et à mesure que celui-ci recule et pénètre dans le guide du manchon mâle, les deux faces des fibres étant en fin de course en appui:l'une contre l'autre par pression d'une fibre contre l'autre. The device according to the present invention comprises two hollow sleeves, one constituting the male sleeve and the other the female sleeve, each of them comprising a clamping means immobilizing the fiber at a certain distance from its end, and a hollow cylindrical guide , traversed by a bore with a diameter very slightly greater than that of the fiber, said bore opening at each end in a frustoconical bowl, the guide of the male sleeve being fixed relative to its sleeve and protruding from it, the guide of the female sleeve being movable against a spring so as to be able to penetrate inside its sleeve by sliding with respect to the optical fiber, the stroke of the movable rod being very slightly greater than the distance separating the two fibers so that when the two sleeves are assembled sleeve against each other the double fiber leaves its guide as the latter moves back and enters the guide of the sleeve m ale, the two faces of the fibers being at the end of the race in support: one against the other by pressing one fiber against the other.

A titre d'exemple non limitatif et pour faciliter la compréhension de l'invention, on a représenté aux dessins annexés
Figure 1 , une vue avec coupe longitudinale des deux parties de la connexion avant assemblage.By way of nonlimiting example and to facilitate understanding of the invention, there is shown in the accompanying drawings
Figure 1, a view with longitudinal section of the two parts of the connection before assembly.

Figure 2 , une vue avec coupe longitudinale des deux parties de la connexion après assemblage. Figure 2, a view with longitudinal section of the two parts of the connection after assembly.

En se reportant à ces figures on voit que la connexion comprend deux éléments 1 et 2 destinés à être assemblés l'un à l'autre par tout moyen mécanique approprié et non représenté parce que ne faisant pas partie de l'invention. Referring to these figures, it can be seen that the connection comprises two elements 1 and 2 intended to be assembled to each other by any suitable mechanical means and not shown because they are not part of the invention.

L'élément 1 est constitué par un manchon creux 3 à l'intérieur duquel est disposée une fibre optique 4. Cette fibre optique est fixée dans le manchon au moyen d'un dispositif de serrage 5 qui est situé à une certaine distance de la face avant ou extrémité 6 dudit manchon 3. A l'extrémité du manchon 3 fait saillie un guide cylindrique 7 percé d'un alésage 8 débouchant dans deux cuvettes tronconiques 9 et 10. The element 1 is constituted by a hollow sleeve 3 inside which is arranged an optical fiber 4. This optical fiber is fixed in the sleeve by means of a clamping device 5 which is located at a certain distance from the face front or end 6 of said sleeve 3. At the end of the sleeve 3 projects a cylindrical guide 7 pierced with a bore 8 opening into two frustoconical bowls 9 and 10.

L'alésage 8 a un diamètre légèrement superieur (de quelques microns) à celui de la fibre optique 4 de façon que celle-ci puisse coulisser à l'intérieur dudit alésage tout en etant guidée par celui-ci. Au contraire, l'alésage 11 du manchon 3 situé entre le moyen de fixation 5 et le guide 7 a un diamètre considérablement plus grand que celui de la fibre 4.The bore 8 has a diameter slightly greater (by a few microns) than that of the optical fiber 4 so that the latter can slide inside said bore while being guided by the latter. On the contrary, the bore 11 of the sleeve 3 located between the fixing means 5 and the guide 7 has a diameter considerably larger than that of the fiber 4.

L'extrémité 12 de la fibre 4 est située à l'intérieur de l'alésage 8. The end 12 of the fiber 4 is located inside the bore 8.

Le guide 7 est solidaire du manchon 3 et fait saillie hors de celui-ci d'une longueur A. The guide 7 is integral with the sleeve 3 and protrudes from the latter of a length A.

L'élément 2 est constitué par un manchon creux 13, analogue au manchon 3, à l'intérieur duquel est disposée une fibre optique 14, identique à la fibre 4. Cette fibre optique 14 est fixée de façon analogue par un moyen de serrage 15 qui est également situé à une certaine distance de la face avant ou extrémité 16 du manchon 13. A l'extrémité du manchon 13 fait légèrement saillie, d'une longueur B un guide cylindrique 17, perce d'un alésage 18, identique à l'alésage 7 qui, de façon analogue débouche dans deux cuvettes tronconiques 19 et 20; le guide cylindrique 18 est mobile à l'intérieur du manchon 13 et est contretenu par un ressort 23, l'alésage 21 situé à l'intérieur du manchon 13 entre le moyen de serrage 15 et le guide 17 est analogue à l'alésage 11. The element 2 is constituted by a hollow sleeve 13, similar to the sleeve 3, inside which is disposed an optical fiber 14, identical to the fiber 4. This optical fiber 14 is similarly fixed by a clamping means 15 which is also located at a certain distance from the front face or end 16 of the sleeve 13. At the end of the sleeve 13 protrudes slightly, of a length B a cylindrical guide 17, pierced with a bore 18, identical to the bore 7 which similarly opens into two frustoconical cups 19 and 20; the cylindrical guide 18 is movable inside the sleeve 13 and is constrained by a spring 23, the bore 21 located inside the sleeve 13 between the clamping means 15 and the guide 17 is similar to the bore 11 .

Dans l'exemple représenté, le guide 7 comporte un alésage 8 débouchant dans deux cuvettes 9 et 10 mais on peut afin de supprimer les angles menager à l'intérieur du guide 7 un espace creux dont les parois ont une forme arrondie analogue à un parabolo9de ou hyperboloRde de révolution. Il en est évidemment de meme en ce qui concerne le guide 17, son alésage 18 et les cuvettes 19 et 20. In the example shown, the guide 7 has a bore 8 opening into two bowls 9 and 10, but it is possible, in order to eliminate the angles, to create a hollow space inside the guide 7, the walls of which have a rounded shape similar to a paraboloid. or hyperboloid of revolution. It is obviously the same with regard to the guide 17, its bore 18 and the cups 19 and 20.

L'extrémité 22 de la fibre 14 fait très légèrement saillie dans le fond de la cuvette 19. The end 22 of the fiber 14 protrudes very slightly from the bottom of the bowl 19.

Les fibres 4 et 14 sont fixées au moyen des dispositifs de serrage 5 et 15 de façon telle que lorsque les guides cylindriques 7 et 17 sont en contact la distance qui sépare leurs extrémites 12 et 22 soit très légèrement inférieure (50 microns environ) à la distance totale (A + B) qui separe les faces 6 et 16. The fibers 4 and 14 are fixed by means of the clamping devices 5 and 15 so that when the cylindrical guides 7 and 17 are in contact the distance which separates their ends 12 and 22 is very slightly less (about 50 microns) than the total distance (A + B) which separates sides 6 and 16.

Le fonctionnement du dispositif ainsi décrit est le suivant: les deux manchons sont rapprochés l'un de l'autre jusqu'à ce que leurs faces 6 et 16 soient en contact et ils sont immobilisés dans cette position par tout moyen approprié. The operation of the device thus described is as follows: the two sleeves are brought towards each other until their faces 6 and 16 are in contact and they are immobilized in this position by any suitable means.

Lors de ce mouvement, le guide 7appui sur le guide 17 qui recule, d'une longueur égale à A + B, en comprimant le ressort 23. Au fur et à mesure que le guide 17 recule, la fibre 14 sort de ce guide et, guidée par la cuvette 9 elle pénètre dans l'alésage 8 et sa face 22 vient en contact avec la face 12 de la fibre 4. Le mouvement de recul du guide 17 se poursuit jusqu'à ce que les faces 6 et 16 des manchons 3 et 13 se touchent; pendant cette dernière phase les deux fibres 4 et 14 reculent dans leurs alésages 8 et 18 et elles se courbent légèrement dans les alésages 11 et 21 par leur elasticité propre; ainsi lorsque les manchons 3 et 13 sont fixés l'un à l'autre les faces 12 et 22 des deux fibres optiques 4 et 14 sont maintenues appliquées l'une contre l'autre par 1 'élasti- cite propre desdites fibres.During this movement, the guide 7 presses on the guide 17 which moves back, of a length equal to A + B, by compressing the spring 23. As the guide 17 moves back, the fiber 14 leaves this guide and , guided by the cup 9 it enters the bore 8 and its face 22 comes into contact with the face 12 of the fiber 4. The recoil movement of the guide 17 continues until the faces 6 and 16 of the sleeves 3 and 13 touch; during this last phase the two fibers 4 and 14 retreat into their bores 8 and 18 and they bend slightly in the bores 11 and 21 by their own elasticity; thus when the sleeves 3 and 13 are fixed to one another the faces 12 and 22 of the two optical fibers 4 and 14 are kept applied against one another by the own elasticity of said fibers.

Lors de la déconnexion les parties mobiles se déplacent en sens inverse, et les extremités -des fibres 4 et 14 sont protegées l'une parce qu'elle est dans l'alésage 8 et l'autre parce qu'elle est dans la cuvette 19. Upon disconnection, the moving parts move in the opposite direction, and the ends of the fibers 4 and 14 are protected, one because it is in the bore 8 and the other because it is in the bowl 19 .

Selon une variante de réalisation, la cuvette 19 peut etre supprimée ce qui allonge d'autant l'alésage 18 et lors de la séparation l'extrémité 22 se trouve à l'intérieur de l'alésage 18.  According to an alternative embodiment, the cup 19 can be omitted which lengthens the bore 18 all the more and during the separation the end 22 is located inside the bore 18.
