Abstract
(EN) An optical cable connection casing (1) includes at least one cable in-out end surface (2) on which at least one connection part (3) and at least one first hollow tubular column (4) are located. The connection part (3) and the first hollow tubular column (4) allow the optical cable (5) to pass in and out the connection casing (1) through the connection part (3) and the first hollow tubular column (4) in the form of double optical cables after the optical cable (5) being oppositely bent without cutting off the optical fiber core of the optical cable (5), respectively; wherein the optical cable (5) will be guided and connected to a branching halfway. The connection part (5) allows the optical cable (5) to be waterproofed by a mechanical waterproof component (7). The first hollow tubular allows the optical cable (5) to be waterproofed by a heat shrinkable tube (9) or an elastic shrinkable tube (8). When the heat shrinkable tube (9) is used, a branching clip (901) is also needed. When the elastic shrinkable tube (8) is in use, an auxiliary fitting for gap-filling and waterproofing is also needed.
(FR) L'invention concerne un boîtier de connexion de câble optique (1) comprenant au moins une surface d'extrémité d'entrée-sortie de câble (2) sur laquelle sont situés au moins un élément de connexion (3) et au moins une première colonne tubulaire creuse (4). L'élément de connexion (3) et la première colonne tubulaire creuse (4) permettent au câble optique (5) d'entrer et de sortir du boîtier de connexion (1) par l'élément de connexion (3) et la première colonne tubulaire creuse (4) sous la forme de câbles optiques doubles après que le câble optique (5) a été plié?sans découpe de l'âme de fibre optique du câble optique (5), respectivement; le câble optique (5) étant guidé et connecté à une moitié de branchement. L'élément de connexion (3) permet au câble optique (5) d'être imperméabilisé par un composant mécanique imperméable (7). La première colonne tubulaire creuse permet au câble optique (5) d'être imperméabilisé par un tube thermorétrécissable (9) ou un tube rétrécissable élastique (8). Lorsque le tube thermorétrécissable (9) est utilisé, un clip de branchement (901) est également requis. Lorsque le tube rétrécissable élastique (8) est utilisé, une garniture auxiliaire pour le remplissage d'espace et l'imperméabilisation est également requis.
