Description
TETE D'ECLATEMENT POUR CABLES A FIBRES OPTIQUES
La présente invention a pour objet une tête d'éclatement pour câbles à fibres optiques.BREAKING HEAD FOR FIBER OPTIC CABLES
The present invention relates to a burst head for fiber optic cables.
Elle concerne en particulier le domaine des réseaux de télécommunications et est destinée à permettre le raccordement d'un câble à fibres optiques à un ou plusieurs autres câbles, ou à un équipement. It relates in particular to the field of telecommunications networks and is intended to allow the connection of a fiber optic cable to one or more other cables, or to equipment.
Les dispositifs réalisés à ce jour sont généralement constitués de deux pièces métalliques relativement complexes et onéreuses, assemblées par vissage ou encliquetage, ce qui ne garantit pas l'étanchéité. Ces équipements sont le plus souvent adaptés à un seul type de câble. The devices produced to date generally consist of two relatively complex and expensive metal parts, assembled by screwing or snap-fastening, which does not guarantee sealing. This equipment is most often adapted to a single type of cable.
De plus, la nature du matériau utilisé ne permet pas de contrôler les fibres optiques une fois le dispositif assemblé.In addition, the nature of the material used does not allow the optical fibers to be checked once the device has been assembled.
Le dispositif suivant la présente invention se propose de remédier à ces inconvénients. En effet, il permet de réaliser, à un coût sensiblement inférieur à celui des autres appareils similaires, des têtes d'éclatement, convenant à tous les types de câbles, à faisceaux, à joncs rainurés hélicoïdaux, ou autres, et permettant de diminuer le temps nécessaire au raccordement des câbles à fibres optiques et par conséquent le prix de la maind'oeuvre. The device according to the present invention proposes to remedy these drawbacks. Indeed, it makes it possible, at a cost substantially lower than that of other similar devices, burst heads, suitable for all types of cables, with bundles, with helical grooved rods, or the like, and making it possible to reduce the time required to connect fiber optic cables and therefore the cost of labor.
I1 est constitué par la combinaison de trois pièces assemblées par collage: une arrivée de câble munie d'un presse-étoupe, un tube intermédiaire transparent permettant le contrôle après assemblage, et une sortie de fibres équipée de tubes souples gainés de protection, l'ensemble étant recouvert d'une gaine thermorétractable translucide après montage. I1 consists of the combination of three parts assembled by gluing: a cable inlet fitted with a cable gland, a transparent intermediate tube allowing control after assembly, and a fiber outlet equipped with flexible tubes sheathed in protection, the assembly being covered with a translucent heat-shrinkable sheath after assembly.
Sur les dessins annexés, donnés à titre d'exemple non limitatif, d'une des formes de réalisation de l'objet de l'invention
La figure 1 représente les divers éléments du dispositif non assemblés.In the accompanying drawings, given by way of nonlimiting example, of one of the embodiments of the subject of the invention
Figure 1 shows the various elements of the device not assembled.
La figure 2 est une coupe longitudinale axiale du dispositif assemblé. Figure 2 is an axial longitudinal section of the assembled device.
La figure 3 est une coupe transversale de la sortie de fibres suivant les flèches A-A de la figure 1. FIG. 3 is a cross section of the fiber outlet according to the arrows A-A of FIG. 1.
Le dispositif, figures 1 à 3, est constitué d'une arrivée de câble 1 pourvue d'un presse-étoupe 2, d'un tube intermédiaire 3 transparent, en méthacrylate de methyle ou équivalent, et d'une sortie de fibres 4 avec tubes gainés 5 de protection. The device, Figures 1 to 3, consists of a cable inlet 1 provided with a cable gland 2, a transparent intermediate tube 3, in methyl methacrylate or equivalent, and a fiber outlet 4 with sheathed protection tubes 5.
Le mode opératoire est le suivant
La gaine extérieure 7 du câble 6 est supprimée sur une longueur d'environ un mètre, et le câble est introduit dans le presse-étoupe 2 et le joint 8. Le ruban de protection (généralement en "KEVLAR" est retourné sur ledit joint afin d'assurer un excellent maintien, puis le presse étoupe est mis en place dans l'arrivée de câble. La gaine interne 9 du câble est coupée à ras de la face interne de l'arrivée de câble, et les gaines individuelles 10 des fibres 11 un peu plus loin. La partie interne de l'entrée de câble est remplie de résine durcissable 12, puis le tube intermédiaire 3 transparent est ajusté et collé sur ladite entrée de câble.The procedure is as follows
The outer sheath 7 of the cable 6 is removed over a length of approximately one meter, and the cable is introduced into the cable gland 2 and the seal 8. The protective tape (generally "KEVLAR" is turned over over the said seal so to provide excellent support, then the cable gland is placed in the cable inlet. The internal sheath 9 of the cable is cut flush with the internal face of the cable inlet, and the individual sheaths 10 of the fibers. 11. The internal part of the cable entry is filled with curable resin 12, then the transparent intermediate tube 3 is adjusted and glued to said cable entry.
La sortie de fibres 4 forme une cuvette dont le fond est pourvu d'une série de trous 13 parallèles à l'axe du dispositif. Les tubes gainés 5 de protection sont débarassés de leur gaine sur une longueur égale à celle de ces trous, puis introduits dans ces derniers. The fiber outlet 4 forms a bowl, the bottom of which is provided with a series of holes 13 parallel to the axis of the device. The sheathed protection tubes 5 are stripped of their sheath over a length equal to that of these holes, then introduced into the latter.
Les fibres optiques 11 dénudées sont passées chacune dans un tube gainé 5, puis la sortie de fibres 4 est fixée par collage sur le tube intermédiaire 3 transparent, et remplie de résine durcissable 12' destinée à obturer les trous 13 non utilisés et à bloquer les tubes souples gainés de protection des fibres optiques. The stripped optical fibers 11 are each passed through a sheathed tube 5, then the fiber outlet 4 is fixed by bonding to the transparent intermediate tube 3, and filled with curable resin 12 'intended to seal the unused holes 13 and to block the sheathed flexible tubes for the protection of optical fibers.
L'ensemble est recouvert d'une gaine thermorétrac table translucide (non représentée). The assembly is covered with a translucent heat shrink tubing (not shown).
Le positionnement des divers éléments constitutifs donne à l'objet de l'invention un maximum d'effets utiles qui n'avaient pas été, à ce jour, obtenus par des dispositifs similaires. The positioning of the various constituent elements gives the object of the invention a maximum of useful effects which had not, to date, been obtained by similar devices.
