Abstract

L'objet de l'invention est d'assurer une mise en œuvre aussi peu onéreuse que possible du contrôle d'un cheminement de câblage de faisceaux électriques. Un faisceau électrique comprend un corps de faisceau électrique et un élément linéaire. Le corps de faisceau électrique est constitué d'au moins un câble électrique; et au moins une partie du corps de faisceau électrique est utilisée comme section de contrôle du cheminement de câblage requise pour le contrôle du cheminement de câblage. L'élément linéaire est associé à la section de contrôle du cheminement de câblage, dans le prolongement de celle-ci. L'élément linéaire, susceptible de déformation plastique, est conçu de telle sorte que la forme de la section de contrôle du cheminement de câblage peut être maintenue le long d'un certain cheminement après déformation plastique.
