  • the tape 14 is provided to keep both end portions 19 a and 19 b of the cross section of the tube main body 19 of the tube 13 overlapped with each other. Therefore, it is possible to prevent the electric wire 11 from jumping out of the tube 13 through the slit 20 when the portion 10a is appropriately bent. Therefore, the wire harness 10 can be reliably assembled.
  • the present invention is applicable to a wire harness routed in an automobile, a method for manufacturing a wire harness, a wire harness forming jig, and a wire harness manufacturing apparatus.

Abstract

L'invention concerne un faisceau de câbles permettant d'empêcher une augmentation du nombre de pièces et d'éviter qu'un fil électrique soit formé plus long que nécessaire. L'invention concerne également un procédé de production associé, un gabarit servant à former le faisceau, ainsi qu'un dispositif de production de ce faisceau. Le faisceau de câbles (10) selon l'invention comprend : un fil électrique (11); et un tube tubulaire (13) fabriqué à partir d'une résine synthétique et destiné à contenir le fil électrique (11) pour le protéger. Lorsque le faisceau de câbles (10) est placé dans une automobile, le tube (13) est plié au niveau d'un emplacement approprié (10a). Le tube (13) comprend un corps (19) et une fente (20) formée sur toute la longueur du corps (19). Le fil électrique (11) est contenu dans le tube linéaire (13), deux extrémités (19a,19b), en coupe transversale du tube (13), se chevauchent sur toute la longueur du tube (13) et l'emplacement approprié (10a) du tube (13) est plié de sorte à ne pas pouvoir inverser le sens de flexion lorsqu'il est placé dans l'automobile (1).
