Abstract

L'invention concerne un dispositif d'épissurage selon le préambule de la revendication 1. On connaît par le document US 4,634,216 un dispositif d'épissurage pour des fibres optiques, les fibres optiques pouvant être fixées par l'intermédiaire d'éléments de ressort dans une rainure dans une unité d'épissurage au moyen d'une force de ressort. Un desserrage de la fixation a lieu au moyen d'un outil supplémentaire qui est poussé entre les éléments de ressort et l'unité d'épissurage, à la suite de quoi les éléments de ressort sont repoussés contre la force de ressort de l'unité d'épissurage. On connaît par le document EP 2 138 875 A1 un dispositif d'épissurage pour des fibres optiques, les fibres optiques étant fixées dans une rainure par l'intermédiaire d'éléments de ressort entre deux éléments d'épissurage d'une unité d'épissurage au moyen d'une force de ressort. Un desserrage de la fixation a lieu au moyen d'une unité d'actionnement qui entoure les éléments de support et présente un moyen d'actionnement qui est poussé entre les deux éléments d'épissurage, à la suite de quoi les deux éléments d'épissurage sont écartés l'un de l'autre contre la force de ressort. Le but de l'invention consiste en particulier à fournir un dispositif d'épissurage de type générique aux propriétés avantageuses pour ce qui est de l'épissurage mécanique d'au moins deux fibres optiques. Le but est atteint selon l'invention par les caractéristiques de la partie caractérisante de la revendication 1, tandis que des réalisations et perfectionnements avantageux de l'invention peuvent être tirés des sous-revendications.
