Description

CONNECTEUR POUR FIBRES OPTIQUES
***************
Le brevet principal N" 8606926 concerne un connecteur pour fibres optiques comprenant un barreau doté d'une rainure longitudinale sur lequel peut tourner un manchon offrant deux fentes parallèles et décalées angulairement et terminées par des encoches.CONNECTOR FOR OPTICAL FIBERS
***************
The main patent N "8606926 relates to a connector for optical fibers comprising a bar provided with a longitudinal groove on which can rotate a sleeve offering two parallel slots and angularly offset and terminated by notches.

Par rotations successives imprimées au manchon, on peut insérer une première fibre optique dans la rainure par une première fente et l'y maintenir puis insérer en aboutement une deuxième fibre optique dans la rainure par une deuxième fente et l'y maintenir. Les différentes opérations pouvant être contrôlées visuellement grâce aux encoches. Deux bagues élastiques venant s'appliquer de part et d'autre du manchon contribuent au maintien des fibres pendant leur insertion. By successive rotations printed on the sleeve, it is possible to insert a first optical fiber into the groove by a first slot and to hold it there then to insert a second optical fiber into the groove by a second slot and to hold it there. The different operations can be visually controlled using the notches. Two elastic rings coming to apply on either side of the sleeve contribute to the maintenance of the fibers during their insertion.

L'additif a pour but d'améliorer le maintien des fibres sur le barreau pendant leur insertion dans la rainure ainsi que pour les manipulations qui suivront. I1 a aussi pour but de maintenir longitudinalement le manchon sur le barreau évitant ainsi un glissement éventuel longitudinal de celui-ci qui viendrait contrarier l'aboutement correct des deux fibres. Cette amélioration sera réalisée par l'adjonction et la fixation sur chaque extrêmité du barreau d'un cylindre de même matière que celui-ci comportant sur une ou plusieurs génératrices intérieures une ou plusieurs rainures arrondies venant en vis à vis de la ou des rainures du barreau. La surface cylindrique extérieure des deux cylindres sera moletée afin que l'opérateur ait une meilleure prise lors des opérations d'insertion. The purpose of the additive is to improve the retention of the fibers on the bar during their insertion into the groove as well as for the manipulations which will follow. I1 also aims to maintain the sleeve longitudinally on the bar thus avoiding a possible longitudinal sliding thereof which would interfere with the correct abutment of the two fibers. This improvement will be achieved by adding and fixing on each end of the bar a cylinder of the same material as the latter comprising on one or more internal generatrices one or more rounded grooves facing the groove or grooves of the bar. The outer cylindrical surface of the two cylinders will be knurled so that the operator has a better grip during the insertion operations.

D'autres caractéristiques et avantages de l'invention ressortiront plus clairement de la description qui va suivre en regard des dessins annexés. Other characteristics and advantages of the invention will emerge more clearly from the description which follows with reference to the appended drawings.

La Figure I représente en perspective un connecteur selon l'invention en cours de montage. Figure I shows in perspective a connector according to the invention during assembly.

La Figure 2 représente le connecteur monté en coupe.  Figure 2 shows the connector mounted in section.

Le connecteur pour fibres optiques représenté aux Figures 1 et 2 se compose de deux pièces principales: un barreau (1), en forme de cylindre de révolution et un manchon(2), de longueur inférieure dont le diamètre intérieur correspond au diamètre extérieur du barreau I, de sorte qu'il peut être engagé sur ce dernier avec un très faible jeu, juste suffisant pour permettre de le faire tourner sur le barreau. The connector for optical fibers shown in Figures 1 and 2 consists of two main parts: a bar (1), in the form of a cylinder of revolution and a sleeve (2), of shorter length whose inside diameter corresponds to the outside diameter of the bar I, so that it can be engaged on the latter with very little play, just enough to allow it to rotate on the bar.

Le barreau (1) comporte une rainure (3) creusée suivant une génératrice sur toute sa longueur. La section droite de cette rainure en forme de V, est dimensionnée de façon à pouvoir loger exactement une fibre optique (F1) ou (F2), de sorte que celle-ci, placée dans la rainure (3), ne fasse qu'à peine saillie (de quelques pm par rapport à la surface cylindrique délimitant le barreau (1). The bar (1) has a groove (3) hollowed out along a generatrix over its entire length. The cross section of this V-shaped groove is dimensioned so as to be able to exactly accommodate an optical fiber (F1) or (F2), so that the latter, placed in the groove (3), does nothing but barely protruding (a few pm relative to the cylindrical surface delimiting the bar (1).

Dans la paroi du manchon (2) sont pratiquées deux fentes longitudinales (4, 5) décalées angulairement par rapport à son axe. La fente 4 commence sur l'une des faces terminales du manchon désignée par la référence (2a) et, prend fin dans la région médiane du manchon, où elle se raccorde à une courte encoche (4a) orientée perpendiculairement. La fente (5) commence sur l'autre face terminale (2 )b du manchon et prend fin de même dans la région médiane du manchon par une encoche perpendiculaire (5a), pratiquée dans le même sens autour de l'axe du manchon que l'encoche (4a) laquelle est orientée vers l'encoche (5), les deux encoches étant positionnées sur le même plan transversal par rapport au dit axe à savoir le plan médian du manchon.Le flanc de chacune des fentes (4,5) dans lequel s'ouvre l'encoche (4b, 5b) présente un chanfrein qui adoucit son arête de raccordement avec la surface interne du manchon (2). In the wall of the sleeve (2) are made two longitudinal slots (4, 5) offset angularly relative to its axis. The slot 4 begins on one of the end faces of the sleeve designated by the reference (2a) and ends in the middle region of the sleeve, where it is connected to a short notch (4a) oriented perpendicularly. The slot (5) begins on the other end face (2) b of the sleeve and similarly ends in the middle region of the sleeve with a perpendicular notch (5a), made in the same direction around the axis of the sleeve as the notch (4a) which is oriented towards the notch (5), the two notches being positioned on the same transverse plane relative to said axis namely the median plane of the sleeve. The side of each of the slots (4,5 ) in which the notch (4b, 5b) opens has a chamfer which softens its connection edge with the internal surface of the sleeve (2).

Deux bagues (6, 7) en caoutchouc sont en outre prévues qui engagées sur le barreau (1) l'enserrent élastiquement. Two rubber rings (6, 7) are further provided which engaged on the bar (1) grip it elastically.

Afin de maintenir longitudinalement le manchon (2) sur le barreau (3) on prévoit sur chaque extrêmité de celui-ci un cylindre (8,9) de même matière comportant sur une ou plusieurs génératrices intérieures une ou plusieurs rainures arrondies (10a, 10 b) venant en vis à vis de la ou des rainures du barreau (1). La surface cylindrique extérieure des deux cylindres (8,9) sera maletée afin que l'opérateur ait une meilleure prise lors des opérations d'insertion. Chaque cylindre (8,9) possédera à une extrêmité un lamage (8a,9a) permettant le logement et le maintien des deux bagues élastiques (6,7). Chaque
cylindre peut être maintenu sur le barreau par vis, goupille ou autre moyen
mécanique ou par collage.In order to maintain the sleeve (2) longitudinally on the bar (3), a cylinder (8, 9) of the same material is provided on each end of the latter, comprising on one or more internal generators one or more rounded grooves (10a, 10 b) facing the bar groove (s) (1). The outer cylindrical surface of the two cylinders (8,9) will be maletté so that the operator has a better grip during the insertion operations. Each cylinder (8,9) will have at one end a counterbore (8a, 9a) allowing the accommodation and the maintenance of the two elastic rings (6,7). Each
cylinder can be held on the bar by screws, pins or other means
mechanical or by bonding.

Le mode opératoire d'aboutement des deux fibres sera strictement identique à celui décrit dans le brevet principal. Le dispositif pourra recevoir des fibres gainées ou non. The procedure for joining the two fibers together will be strictly identical to that described in the main patent. The device can receive sheathed fibers or not.

Dans le cas du raccordement de deux fibres plastiques de diamètre 1 mm par exemple les bagues élastiques (6,7) pourront être supprimées. In the case of the connection of two plastic fibers with a diameter of 1 mm, for example the elastic rings (6,7) can be eliminated.

Dans l'hypothèse d'un raccordement définitif un adhésif polymérisable aux UV pourra être introduit par les extrêmités des rainures (10a, 10b).  In the event of a definitive connection, a UV-curable adhesive may be introduced through the ends of the grooves (10a, 10b).
