  • Patent number: 10886683
    Abstract: A method for manufacturing a terminal-equipped electric wire includes a coating forming process for forming, on a terminal-equipped electric wire having a terminal including a core wire crimping part that holds a core wire of an electric wire and a covering crimping part crimped to a covering of the electric wire, a coating of an ultraviolet-curing resin that integrally covers the core wire and the terminal, and an irradiating process for irradiating the coating with ultraviolet rays. At the coating forming process, while a discharge port that intermittently ejects droplets of the ultraviolet-curing resin and the terminal-equipped electric wire are moved relative to each other, the coating is formed from the ultraviolet-curing resin ejected from the discharge port. A direction of the relative movement of the discharge port and the terminal-equipped electric wire at the coating forming process includes directions orthogonal to an ejection direction of the droplets.
