Abstract

La présente invention vise à proposer un faisceau de câbles présentant une structure qui réduit la plage de variation du corps principal d'un faisceau de câbles tout en assurant la flexibilité d'assemblage du faisceau de câbles. Le faisceau de câbles selon la présente invention est constitué d'un ensemble de câbles et d'une feuille en polyéthylène en forme de plaque fixée par un élément de fixation entre un premier et un second point dans la direction longitudinale de l'ensemble de câbles. La feuille en polyéthylène en forme de plaque commande la flexion de telle manière que la feuille en polyéthylène en forme de plaque ne peut fléchir en même temps que l'ensemble de câbles que dans une direction de flexion admissible qui est orthogonale à la direction longitudinale ci-dessus.
