Description
Dispositif d'éclatement d'un faisceau de fibres optiques en fibres optiques unitaires.Device for splitting a bundle of optical fibers into unitary optical fibers.
La présente invention concerne un dispositif d'éclatement d'un faisceau de fibres optiques en fibres optiques unitaires, le faisceau comportant un nombre quelconque de fibres, étant engagé dans un tube souple de protection. The present invention relates to a device for bursting a bundle of optical fibers into unitary optical fibers, the bundle comprising any number of fibers, being engaged in a flexible protection tube.
Le raccordement d'un câble à fibres optiques à un autre câble ou à un équipement impose l'éclatement de l'extrémité de ce câble. Connecting a fiber optic cable to another cable or to equipment requires the end of this cable to burst.
Pour un câble à jonc rainuré comportant un faisceau de fibres par rainure, on réalise d'abord l'éclatement du câble en faisceaux indépendants, introduits chacun dans un tube souple de protection, à l'aide d'une tête d'éclatement connue ayant fait l'objet d'une suggestion antérieure. For a grooved rod cable comprising a bundle of fibers per groove, the cable is first burst into independent bundles, each introduced into a flexible protection tube, using a known burst head having is the subject of an earlier suggestion.
I1 faut ensuite réaliser l'éclatement de chaque faisceau de fibres en fibres optiques unitaires introduites chacune dans un tube souple de protection. It is then necessary to break up each bundle of fibers into unitary optical fibers each introduced into a flexible protection tube.
Selon l'art antérieur connu, il n'existe aucun dispositif permettant l'éclatement d'un faisceau en fibres unitaires. According to the known prior art, there is no device allowing the bursting of a bundle of unit fibers.
La présente invention a pour but de fournir un tel dispositif d'éclatement qui, associé à la tête d'éclatement décrite dans la suggestion antérieure, permet l'éclatement complet d'un câble à jonc rainuré comportant un faisceau de fibres par rainure, c'est-à-dire la protection individuelle de chaque fibre optique pour la raccorder à une autre fibre ou à un équipement. The object of the present invention is to provide such a bursting device which, associated with the bursting head described in the previous suggestion, allows the complete bursting of a grooved rod cable comprising a bundle of fibers per groove, c is to say the individual protection of each optical fiber to connect it to another fiber or to equipment.
La présente invention a pour objet un dispositif d'éclatement d'un faisceau de fibres optiques en fibres optiques unitaires, le faisceau de fibres étant engagé dans un tube souple de protection, caractérisé en ce qu'il comporte un manchon de raccordement et une buse de répartition, le manchon de raccordement étant raccordé par une de ses extrémités au tube de protection du faisceau, la buse de répartition, munie de fentes radiales débouchant dans des orifices cylindriques borgnes de même axe, étant raccordée par une de ses extrémités à des tubes souples de protection introduits chacun dans un orifice cylindrique et recevant chacun une fibre optique, les deux autres extrémités, celle du manchon et celle de la buse, étant raccordées par encliquetage. The present invention relates to a device for bursting a bundle of optical fibers into unitary optical fibers, the bundle of fibers being engaged in a flexible protective tube, characterized in that it comprises a connection sleeve and a nozzle. distribution, the connection sleeve being connected by one of its ends to the beam protection tube, the distribution nozzle, provided with radial slots opening into blind cylindrical orifices of the same axis, being connected by one of its ends to tubes protective hoses each introduced into a cylindrical orifice and each receiving an optical fiber, the other two ends, that of the sleeve and that of the nozzle, being connected by snap-fastening.
En outre, ce dispositif comporte avantageusement l'une des caractéristiques suivantes - chaque orifice cylindrique borgne de la buse est prolongé par une extrémité arrondie d'une fente dont le diamètre est inférieur au diamètre interne d'un tube souple de protection introduit dans la buse, afin d'obtenir une introduction certaine de la fibre dans son tube, sans détérioration de celle-ci, - le manchon de raccordement comporte une couronne interne en saillie et deux fentes longitudinales, - la buse de répartition comporte, sur sa périphérie, une gorge recevant la couronne interne du manchon de raccordement, - ce dispositif comporte un joint torique comprimé, après encliquetage, entre le manchon de raccordement et la buse de répartition. In addition, this device advantageously includes one of the following characteristics - each blind cylindrical orifice of the nozzle is extended by a rounded end of a slot whose diameter is less than the internal diameter of a flexible protective tube introduced into the nozzle , in order to obtain a certain introduction of the fiber into its tube, without deterioration of the latter, - the connection sleeve comprises an internal projecting crown and two longitudinal slots, - the distribution nozzle comprises, on its periphery, a groove receiving the internal crown of the connection sleeve, - this device comprises a compressed O-ring, after snap-fastening, between the connection sleeve and the distribution nozzle.
Il est décrit ci-après, à titre d'exemple et en référence au dessin annexé, un dispositif d'éclatement selon l'invention. There is described below, by way of example and with reference to the accompanying drawing, a bursting device according to the invention.
La figure 1 montre, en coupe longitudinale, un dispositif d'éclatement complet dont le montage est terminé. Figure 1 shows, in longitudinal section, a complete bursting device whose assembly is completed.
La figure 2 montre une section de la buse de répartition selon II de la figure 1, les tubes de protection des fibres unitaires étant enlevés. Figure 2 shows a section of the distribution nozzle along II of Figure 1, the protective tubes of the individual fibers being removed.
Dans la figure 1, le dispositif de raccordement 10 est complet, et son montage est terminé. On voit donc un dispositif composé d'un manchon 20 et d'une buse 30, ces deux éléments étant encliquetés. In Figure 1, the connecting device 10 is complete, and its assembly is completed. We therefore see a device composed of a sleeve 20 and a nozzle 30, these two elements being snapped.
Le manchon 20 reçoit à une extrémité un tube souple 1 enfermant un faisceau de fibres optiques 2, le tube étant fixé sur le manchon par un filetage 21. Il peut bien entendu être fixé par d'autres moyens. The sleeve 20 receives at one end a flexible tube 1 enclosing a bundle of optical fibers 2, the tube being fixed on the sleeve by a thread 21. It can of course be fixed by other means.
A son autre extrémité, le manchon 20 comporte un évidement 22 dans lequel est ajustée la buse 30. Cet évidement 22 laisse subsister à l'ex- trémité du manchon une couronne interne 23 en saillie par rapport à l'évidement. Ce manchon comporte également deux fentes longitudinales 24, diamètralement opposées, donnant de l'élasticité à cette extrémité du manchon, élasticité nécessaire à l'encliquetage. At its other end, the sleeve 20 has a recess 22 in which the nozzle 30 is adjusted. This recess 22 leaves an internal crown 23 projecting from the recess at the end of the sleeve. This sleeve also comprises two longitudinal slots 24, diametrically opposite, giving elasticity to this end of the sleeve, elasticity necessary for the latching.
La buse de répartition 30 comporte, dans cet exemple, dix fentes radiales 31 mieux visibles en figure 2, constituées sur toute la lon guéer de la buse. Ces fentes radiales 31 débouchent dans des orifices cylindriques borgnes 32, également bien visibles en figure 2, recevant sur toute leur longueur des tubes de protection 3. Ces tubes peuvent être maintenus, par exemple, par collage. The distribution nozzle 30 comprises, in this example, ten radial slots 31 better visible in FIG. 2, formed over the entire length of the nozzle. These radial slots 31 open into blind cylindrical orifices 32, also clearly visible in FIG. 2, receiving over their entire length protective tubes 3. These tubes can be held, for example, by gluing.
Les fentes radiales 31 se terminent, en dehors des orifices 32, par une forme demi-circulaire 31A, visible en figure 2. L'axe de cette forme demi-circulaire correspond avec l'axe d'un orifice et comme le diamètre de cette forme est inférieur au diamètre interne d'un tube de protection, la mise en place d'une fibre est rendue sûre par une mise en place au fond de la fente et une poussée dans l'axe du tube. The radial slots 31 end, outside the orifices 32, by a semicircular shape 31A, visible in FIG. 2. The axis of this semicircular shape corresponds with the axis of an orifice and as the diameter of this shape is less than the internal diameter of a protective tube, the establishment of a fiber is made safe by an establishment at the bottom of the slot and a thrust in the axis of the tube.
La buse de répartition comporte également, côté manchon, un chanfrein 34 qui facilite l'introduction de la buse 30 dans le manchon 20, et chaque fente radiale 31 comporte un chanfrein correspondant 31B qui donne à une fibre un rayon de courbure minimum. The distribution nozzle also comprises, on the sleeve side, a chamfer 34 which facilitates the introduction of the nozzle 30 into the sleeve 20, and each radial slot 31 has a corresponding chamfer 31B which gives a fiber a minimum radius of curvature.
Cette buse 30 comporte également une rainure 33 complémentaire de la couronne interne 23 du manchon 20, cette complémentarité assurant 1' encliquetage. This nozzle 30 also includes a groove 33 complementary to the internal crown 23 of the sleeve 20, this complementarity ensuring the snap-fastening.
Après encliquetage, une chambre 25 subsiste à l'intérieur du manchon de raccordement 20, cette chambre assurant également aux fibres optiques un rayon de courbure minimum. After snap-fastening, a chamber 25 remains inside the connection sleeve 20, this chamber also ensuring that the optical fibers have a minimum radius of curvature.
Entre un épaulement de l'évidement 22 du manchon 20 et un épaulement de la buse 30, est comprimé un joint torique 35 qui bloque en rotation la buse et le manchon afin d'éviter le cisaillement des fibres. Between an shoulder of the recess 22 of the sleeve 20 and a shoulder of the nozzle 30, an O-ring 35 is compressed which locks the nozzle and the sleeve in rotation in order to avoid shearing of the fibers.
Bien entendu un code couleur est utilisé afin de repérer les fibres 2 et les tubes 3 correspondants. Of course, a color code is used to identify the fibers 2 and the corresponding tubes 3.
Une opération d'éclatement s'effectue de la manière suivante - on introduit les fibres optiques 2, sortant du tube de protection 1, dans le manchon 20, - on visse le tube 1 dans le filetage 21 du manchon 20, - par une opération préalable, on introduit tous les tubes de protection 3 dans les orifices cylindriques 32 de la buse 30, - on introduit chaque fibre dans sa fente radiale 31 correspondante, puis par poussée dans le tube de protection 3 correspondant, - quand toutes les fibres sont introduites, on introduit la buse 30 dans le manchon 20 jusqu'à I'encliquetage. A bursting operation is carried out as follows - the optical fibers 2, leaving the protective tube 1, are introduced into the sleeve 20, - the tube 1 is screwed into the thread 21 of the sleeve 20, - by an operation beforehand, all the protective tubes 3 are introduced into the cylindrical orifices 32 of the nozzle 30, - each fiber is introduced into its corresponding radial slot 31, then by pushing into the corresponding protection tube 3, - when all the fibers are introduced , the nozzle 30 is introduced into the sleeve 20 until it clicks into place.
