Abstract

La présente invention concerne un ensemble répartiteur dont l'actionneur pivotant (24) présente d'une part une partie à grand diamètre (68) et d'autre part une partie à petit diamètre (66). La partie à petit diamètre reçoit un petit fil devant aboutir à une lame IDC à petite fente (25), la partie à plus grande cavité recevant un gros fil devant aboutir à une lame IDC à grande fente (25'). Il est possible d'accueillir en bornier des fils d'une gamme plus étendue de calibres sans qu'il y ait besoin de forces d'actionnement plus importantes, et en outre, sans risque d'endommager les lames IDS à petites fentes, ce qui fait qu'il est possible d'utiliser le connecteur plusieurs fois. L'ensemble connecteur comporte également un module enfichable (80'', 80''') permettant la connexion ou la déconnexion des borniers des faces tableau et ligne d'abonné de l'ensemble, soit pour exploitation, soit pour test, suivant le cas.
