Title:
端子付き電線及びその製造方法
Document Type and Number:
Japanese Patent JP6845188
Kind Code:
B2
Abstract:
An electric wire with a terminal and manufacturing method thereof is provided. In the electric wire with the terminal, the protective member, the core wire, and the terminal fitting are integrally connected to each other by ultrasonic vibration applied via the protective member from an ultrasonic horn in a state in which the core wire is sandwiched between the protective member and the terminal fitting. Therefore, there is no possibility that the ultrasonic horn directly presses the core wire, and the edge (particularly, the rear edge) of the pressing portion of the ultrasonic horn is direct in contact with the core wire. Thereby, at the time of ultrasonic bonding, stress concentration due to the edge (particularly the rear edge) of the pressing portion of the ultrasonic horn with respect to the core wire can be relaxed, and disconnection of the core wire can be suppressed.
