Abstract
Official abstract text for this publication.
A method of manufacturing a terminal-formed electric wire includes a welding member placing process in which at least one welding member formed of metal having a melting point lower than that of a plurality of metal strands included in a core wire is arranged to the core wire of at least a terminal-forming target portion of the electric wire, and a terminal forming process in which the exposed terminal-forming target portion is interposed between first and second electrodes having a shape corresponding to a desired terminal shape, at least the welding member in the terminal-forming target portion is melted by electrically conducting the first and second electrodes while pressing the terminal-forming target portion with the first and second electrodes, and the melted metal is then solidified, so that the terminal-forming target portion is formed as a terminal portion having a desired terminal shape.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of manufacturing a terminal-formed electric wire, the method comprising: a strand dividing process in which a plurality of metal strands included in a core wire of a terminal-forming target portion of an electric wire are divided into a plurality of strand groups, a welding member placing process in which at least one welding member formed of metal having a melting point lower than that of the plurality of strands is arranged to the core wire of at least the terminal-forming target portion of the electric wire; and a terminal forming process in which the exposed terminal-forming target portion is interposed between a pair of electrodes having a shape corresponding to a desired terminal shape, at least the welding member in the terminal-forming target portion is melted by electrically conducting the pair of electrodes while pressing the terminal-forming target portion with the pair of electrodes, and melted metal is solidified by stopping electric conduction to the pair of electrodes, so that the terminal-forming target portion is formed as a terminal portion having the terminal shape, wherein in the welding member placing process, the welding member having a flat shape is placed between the adjacent strand groups. 2. A method of manufacturing a terminal-formed electric wire, the method comprising: a welding member placing process in which at least one welding member formed of metal having a melting point lower than that of a plurality of metal strands included in a core wire is arranged to the core wire of at least a terminal-forming target portion of an electric wire; and a terminal forming process in which the exposed terminal-forming target portion is interposed between a pair of electrodes having a shape corresponding to a desired terminal shape, at least the welding member in the terminal-forming target portion is melted by electrically conducting the pair of electrodes while pressing the terminal-forming target portion with the pair of electrodes, and melted metal is solidified by stopping electric conduction to the pair of electrodes, so that the terminal-forming target portion is formed as a terminal portion having the terminal shape, wherein in the welding member placing process, the welding member having the same shape as that of the strand is inserted between the plurality of strands.
