Abstract

L'invention concerne un ensemble (1) pour étanchéifier une liaison par câble dans un véhicule automobile qui comprend une rondelle d'étanchéité (3), un boîtier (5) et un joint de traversée (7) qui comprennent chacun un évidement (13, 15, 17) qui s'étend sensiblement le long d'un axe longitudinal (L) de l'ensemble (1) et qui pénètre respectivement dans la rondelle d'étanchéité (3), dans le boîtier (5) et dans le joint de traversée (7). Dans un état ordonné, un câble (9) est au moins en partie disposé dans les évidements (13, 15, 17) tandis que la rondelle d'étanchéité (3) et le joint de traversée (7) sont disposés l'un à côté de l'autre le long de l'axe longitudinal (L) et, par rapport à une direction radiale, verticalement à l'axe longitudinal (L) dans l'évidement (15) du boîtier (5) et ainsi entre le boîtier (5) et le câble (9). Au moyen de la rondelle d'étanchéité (3) est exercée sur le joint de traversée (7) une force mécanique qui comprime le joint de traversée (7) le long de l'axe longitudinal (L) et qui le déforme d'une part contre le boîtier (5) et d'autre part le déforme contre le câble (9) afin d'étanchéifier de cette façon une zone interne (16) du boîtier (5) par rapport à une zone externe (14).
