電線の製造方法および電線製造装置
Document Type and Number:
Japanese Patent JP7225166
Kind Code:
B2
Abstract:
An electric wire manufacturing method includes: a step of placing a core wire including a plurality of strands inside a tubular jig; and a step of forming a joined portion that integrates the strands by emitting laser light along an axial direction of the core wire toward a tip of the core wire placed inside the jig. In the placing step, the core wire is placed with a gap between an inner wall surface of the jig and an outer circumferential surface of the core wire while the tip of the core wire faces upward relative to a horizontal line. In the step of forming the joined portion, the joined portion is formed by filling the gap with a melted substance of the strands.
