Method for manufacturing terminal with electric wire

1. A method for manufacturing a terminal with an electric wire operatively associated with a supplying apparatus including a dispenser having a metal nozzle, 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; and

supplying a sealing material, delivered by the metal nozzle to the wire-terminal connection portion,

wherein during supply of the sealing material, moving the metal nozzle occurs in X-, Y- and Z-directions over the wire-terminal connection portion or changing a relative position between the wire-terminal connection portion and the metal nozzle occurs in the X-, Y- and Z-directions, and

the supplying the sealing material in a state electrically charged by applying a voltage between the metal nozzle and the terminal fitting such that the sealing material covers whole circumference of the wire-terminal connection portion around an axis of the terminal, including an opposite side of a supply position to which the sealing material is supplied by the metal nozzle.

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

wherein forming the wire-terminal connection portion in a range comprising:

providing a conductor crimping part in which crimping the conductor exposed portion occurs by a conductor crimping piece of the terminal fitting;

providing a non-crimping part around the conductor crimping part; and

providing a coating crimping part in which crimping the resin coating in a vicinity of the conductor exposed portion occurs by a coating crimping piece of the terminal fitting, and

wherein the sealing material is supplied to cover the wire-terminal connection portion formed in the range, and during supply of the sealing material, at least in a position of the non-crimping part, the metal nozzle is moved in the X-, Y- and Z-directions or the relative position between the wire-terminal connection portion and the metal nozzle is changed in the X-, Y- and Z-directions.

3. The method for manufacturing a terminal with an electric wire according to claim 1 , further comprising:

determining an initial position of the metal nozzle prior to supply of the sealing material based on an image of the wire-terminal connection portion which is captured from a predetermined position by a camera.

4. The method for manufacturing a terminal with an electric wire according to claim 1 , wherein the sealing material is supplied in a stringy condition.

5. The method for manufacturing a terminal with an electric wire according to claim 4 , wherein the sealing material is supplied in the stringy condition with tracking a three-dimensional shape of the wire-terminal connection portion with the metal nozzle.
