ALUMINUM ELECTRIC WIRE, HARNESS, AND METHOD FOR PRODUCING HARNESS

摘要

PROBLEM TO BE SOLVED: To provide a technique for dealing with dissimilar metal contact corrosion (electric corrosion) by a totally new constitution.SOLUTION: There is provided an aluminum electric wire 2, including: a core wire 4 made of aluminum or an aluminum alloy, formed with an oxide film 7 thicker than a natural oxide film at the outer circumferential face 6; and an insulation covering 5 of covering the core wire 4. Also provided is a harness 1 including: the aluminum electric wire 2 including the core wire 4 made of aluminum or an aluminum alloy, formed with the oxide film 7 thicker than a natural oxide film at the outer circumferential face 6 and the insulation covering 5 of covering the core wire 4; and a crimp terminal 3 made of copper or a copper alloy, crimped to the core wire 4 of the aluminum electric wire 2. Also provided is a method for producing the harness 1, comprising: a coating step (S130) where the crimp terminal 3 made of copper or a copper alloy is coated with corrosion prevention treatment agent; and a connection step (S160) where the core wire 4 of the aluminum electric wire 2 having the core wire 4 made of aluminum or an aluminum alloy, formed with the oxide film 7 thicker than the natural oxide film at the outer circumferential face 6 and the insulation covering 5 of covering the core wire 4 is crimped with the crimp terminal 3.SELECTED DRAWING: Figure 3
