Abstract

Un faisceau de fils (11) selon un mode de réalisation de la présente invention, est équipé : d'un premier fil électrique de blindage (12) qui a un premier fil central (12a) et un premier élément tressé (12c) ; des seconds fils électriques de blindage (13, 14) qui ont des seconds fils centraux (13a, 14a) et des seconds éléments tressés (13c, 14c) ; une borne sertie (15) qui relie le premier fil central (12a) et les seconds fils centraux (13a, 14a) l'un à l'autre ; et une partie isolante (16) qui recouvre la périphérie externe de la borne sertie (15). Les seconds éléments tressés (13c, 14c) entrent directement en contact avec la partie isolante (16) en recouvrant la partie isolante (16) tout en étant directement reliés au premier élément tressé (12c).
