Abstract

La présente invention vise à fournir une technique permettant de sertir, en une pose, différentes bornes sur plusieurs fils électriques recouverts compris dans un câble. Le dispositif de traitement de fil électrique de l'invention comprend plusieurs fils électriques recouverts contenus dans un câble, dont les parties d'extrémité respectives sont dans un état maintenu, qui sont envoyés le long d'un trajet de transport en un lot, et les parties d'extrémité des fils électriques recouverts maintenus sont traitées séquentiellement par des unités de traitement de fil électrique alignées le long du trajet de transport. Les étapes de traitement consistent par exemple : à découper de manière séquentielle les pointes des parties d'extrémité respectives des fils électriques recouverts maintenus ; à dénuder les revêtements d'isolation des parties d'extrémité des fils électriques recouverts qui ont été ajustées de manière uniforme ; et à sertir une borne sur chaque fil des fils centraux exposés de chaque partie des parties d'extrémité dénudées. Afin de permettre à différents types de bornes d'être sertis sur les parties d'extrémité à l'étape de sertissage, une pluralité de mécanismes de sertissage sont prévus, et une unité de commande choisit le mécanisme de sertissage à utiliser.
