Abstract

L'invention concerne un ensemble adaptateur doté d'un boîtier d'adaptateur et d'une barre transversale. La barre transversale, lorsqu'elle est enfoncée, libère un ou plusieurs connecteurs de fibres optiques fixés au ou aux orifices de l'adaptateur. La barre transversale est remplacée par un ressort de rappel qui fixe une languette de libération avec des nervures sur un côté du corps de languette de libération. Le nombre de nervures détermine le nombre de connecteurs qui peuvent être libérés ensemble lorsque l'utilisateur tire sur l'arbre de la languette de libération.
