Abstract

A method for manufacturing a terminal with an electric wire includes: forming a conductor exposed portion by removing a resin coating of an electric wire; forming a wire-terminal connection portion by connecting a terminal fitting to a position of the conductor exposed portion; supplying a sealing material made of ultraviolet-curing resin from a nozzle to form a sealing portion covering the wire-terminal connection portion; and curing the sealing material by irradiation with ultraviolet rays from a UV light. During curing of the sealing material, a reflector is used to allow the ultraviolet rays to be reflected toward the sealing material supplied to the wire-terminal connection portion.

Claims (11)

1. A method for manufacturing a terminal with an electric wire operatively associated with an apparatus that includes a nozzle, a reflector and UV light, the method comprising:

forming a conductor exposed portion by removing a resin coating of an electric wire;

forming a wire-terminal connection portion by connecting a terminal fitting to a position of the conductor exposed portion;

providing the reflector;

placing the wire-terminal connection portion at a location relative to the reflector;

supplying a sealing material made of ultraviolet-curing resin from the nozzle to form a sealing portion covering the wire-terminal connection portion; and

curing the sealing material by irradiation with ultraviolet rays from the UV light,

wherein during supplying the sealing material, applying a voltage between the nozzle and the terminal fitting, supplying the sealing material that has been charged from the nozzle so as to be attracted to the wire-terminal connection portion, and keeping the sealing material so as to stay at the wire-terminal connection portion, and

wherein during curing of the sealing material, reflecting the ultraviolet rays with the reflector toward the sealing material supplied to the wire-terminal connection portion in a state attracted to the wire-terminal connection portion and stayed at the wire-terminal connection portion.

2. The method for manufacturing a terminal with an electric wire according to claim 1 ,

wherein during curing of the sealing material, disposing the UV light and the reflector such that the irradiation with ultraviolet rays is performed on a whole circumference of the wire-terminal connection portion around an axis of the terminal fitting.
