Abstract

A terminal with a wire having a high sealing property, a manufacturing method thereof, and a wire harness are provided. The terminal with the wire includes an aluminum wire and a crimp terminal. A resin covering member is removed from the aluminum wire to form a conductor exposed portion (a wire forming process). The crimp terminal is connected to the conductor exposed portion to form a wire-terminal connection portion (a wire-terminal connection process). Then, an anticorrosion portion is formed such that a voltage is applied between the crimp terminal and a metal nozzle and an electrified anticorrosion material is supplied from the metal nozzle to the wire-terminal connection portion in a state of being attracted (an anticorrosion material supply process). Further, the anticorrosion portion is formed by irradiating the anticorrosion material with an ultraviolet ray to be UV-cured (an anticorrosion material curing process).

First claim

What is claimed is:

1. A manufacturing method of a terminal with a wire, comprising:
a wire forming process in which a resin covering member is removed from the wire to form a conductor exposed portion;
a wire-terminal connection process in which a terminal metal fitting is connected at a position of the conductor exposed portion to form a wire-terminal connection portion; and
a sealing material supply process in which a voltage is applied between the terminal metal fitting and a metal nozzle, and an electrified sealing material is supplied from the metal nozzle to the wire-terminal connection portion in a state of being attracted to form a sealing portion for covering the wire-terminal connection portion.

2. The manufacturing method of the terminal with the wire according to claim 1 ,
wherein, in the sealing material supply process, the electrified sealing material is supplied to the wire-terminal connection portion in one predetermined direction, and the electrified sealing material is spread over the entire peripheral surface around an axis of the terminal metal fitting in the wire-terminal connection portion by an electrostatic force.

3. The manufacturing method of the terminal with the wire according to claim 1 ,
wherein the electrified sealing material is supplied in a substantial stringiness state continuing from the metal nozzle to the wire-terminal connection portion.

4. The manufacturing method of the terminal with the wire according to claim 1 , further comprising a sealing material curing process UV-curing the electrified sealing material so as to form the sealing portion as a process after the sealing material supply process.

5. The manufacturing method of the terminal with the wire according to claim 1 ,
wherein, as the wire-terminal connection process, the wire-terminal connection portion is formed in a range containing a conductor caulking portion which caulks the conductor exposed portion using a conductor caulking piece of the terminal metal fitting, a non-caulking portion near the conductor caulking portion, and a covering-member caulking portion which caulks the resin covering member near the conductor exposed portion using a covering-member caulking piece of the terminal metal fitting.
