Abstract

L'invention concerne un faisceau de câbles (11) qui est équipé : d'un premier câble blindé (12) qui a un premier fil d'âme (12a) et un premier élément de blindage électromagnétique (12c) ; des seconds câbles blindés (13, 14) qui ont chacun un second fil d'âme (13a, 14a) et un second élément de blindage électromagnétique (13c, 14c) ; un fusible (15) qui relie le premier fil central (12a) et les seconds fils centraux (13a, 14a) les uns par rapport aux autres ; une section de liaison (20) qui comprend le fusible (15) et dans laquelle le premier fil central (12a) et les seconds fils centraux (13a, 14a) sont connectés ; et un élément isolant (18) pour recouvrir la périphérie externe de la section de liaison (20). Le premier élément de blindage électromagnétique (12c) et les seconds éléments de blindage électromagnétique (13c, 14c) fonctionnent ensemble pour recouvrir la périphérie externe de l'élément isolant (18) tout en étant reliés l'un à l'autre.
