Abstract

L'objectif de l'invention est de fournir une structure de fixation qui, lors de la fixation d'une variété d'éléments extérieurs à un fil électrique, peut être couramment utilisée. Ce faisceau de fils comprend un élément extérieur fonctionnel formé en une forme de feuille, et un fil électrique posé de telle sorte qu'une région dans au moins une partie le long de sa direction de longueur chevauche l'élément extérieur fonctionnel. Au moins une partie de la section dans laquelle le revêtement isolant du fil électrique chevauche l'élément extérieur fonctionnel est soudée. En tant que mode du faisceau de fils, on peut considérer un mode dans lequel, par exemple, l'au moins une partie de la section dans laquelle le revêtement isolant du fil électrique chevauche l'élément extérieur fonctionnel est soudée par ultrasons.
