Abstract

L'invention concerne un connecteur (1) tel qu'il peut par ex. être placé à l'extrémité d'un câble (3), plusieurs connecteurs (1) de ce type pouvant être logés dans un boîtier d'un connecteur multiple. Le connecteur (1) comprend un logement de contact (5) de forme allongée ainsi qu'une attache de câble (7) montée sur le logement de contact (5) et pourvue d'une zone de maintien (9) servant à maintenir les torons (11) du câble dénudé (3). Le connecteur (1) selon l'invention est équipé d'un élément supplémentaire (29) de protection des torons, conçu de manière à empêcher que les extrémités des torons (11) maintenus dans l'attache de câble (7) ne dépassent latéralement de l'attache de câble (7). On évite ainsi tout endommagement des extrémités de câble dépassant du connecteur (1), par ex. lors de l'introduction du connecteur (1) dans un mat d'étanchéité d'un connecteur multiple.
