[0120] The terminals with wires are constructed to include aluminum wires and crimp terminals. The aluminum electric wire is configured to include an aluminum or aluminum alloy conductor and an insulating resin coating member covering the conductor. The resin-coated member was removed from the aluminum electric wire to form a conductor exposed portion. The crimp terminal includes a caulking portion as a crimp portion. In the caulking portion, a conductor caulking sheet and a covered member caulking sheet are formed. Terminals with wires The caulking portion is crimped to the conductor exposed portion to form a wire-to-terminal connection. Then, an anticorrosion portion is formed to cover the wire-terminal connection portion. The anti-corrosion portion is formed such that a voltage is applied between the crimp terminal and the metal nozzle, and the electrified anti-corrosion material is supplied from the metal nozzle to the wire-terminal connection portion in a state of bein...

[0163] in the above reference Figure 13A with 13B In the conventional technique described, the anti-corrosion material 117 is dripped from the respective nozzles 116 of the two dispensers. Then, the anticorrosion material 117 thus dropped and coated hardens to form the anticorrosion portion 115 . In the forming method of the conventional example, it takes time to harden the anticorrosion material 117, and when liquid dripping or sink marks occur, there is a problem in manufacturability. In addition, in the case where the coverage range of the anticorrosion material 117 is not clearly defined, the anticorrosion portion 115 may be insufficiently formed.

[0164] Furthermore, in the above conventional art, in the case where bubbles are generated in the coated anticorrosion material 117 and the bubbles are broken when the anticorrosion material 117 is hardened, the function of the anticorrosion portion 115 may deteriorate.

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).

Description

technical field [0001] The present invention relates to a terminal with wires, a method of manufacturing the terminal with wires, and a wire harness including the terminal with wires including dissimilar metals formed in wire and terminal metal fittings Corrosion protection at the joint. Background technique [0002] For example, in order to electrically connect devices installed in the vehicle, a wire harness is routed in the vehicle. The wire harness is configured to include a bundle of wires and various types of connectors provided at ends of the bundle of wires. The connector of the wire harness is configured to include an insulating connector housing and a plurality of conductive terminal metal fittings accommodated in a terminal accommodating chamber of the connector housing. Terminal metal fittings are provided at the ends of the electric wires in the electric wire harness. As the electric wires, copper electric wires (conductors made of copper or copper alloy in a...
