Abstract

L'objectif de la présente invention est de réaliser une structure de câblage de mise à la terre pour un véhicule de telle sorte que l'insertion de câbles de mise à la terre par des trous d'insertion de panneau n'est pas nécessaire et qu'une augmentation du poids total d'un faisceau de câbles peut être réduite au minimum. Un élément de conduction sous plancher (42) est acheminé dans une section sous plancher (38) d'un compartiment moteur (12) et une section sous plancher (40) d'un compartiment passager (14) de manière à s'étendre dans les deux sections sous plancher (38, 40). La région de l'élément de conduction sous plancher (42) sur le côté compartiment moteur est connectée à la borne négative d'une batterie (18), et la région de l'élément de conduction sous plancher (42) sur le côté compartiment passager est pourvue d'une première partie de conduction (46) qui est connectée à l'élément de conduction sous plancher (42) et fait saillie de la section sous plancher (40) pour pénétrer dans le compartiment passager (14). De multiples câbles de mise à la terre côté dispositif (36) sont connectés à la première partie de conduction (46).
