Title:
TERMINAL AND ALUMINUM WIRE CONNECTION STRUCTURE OF TERMINAL
Document Type and Number:
WIPO Patent Application WO/2015/115174
Kind Code:
A1
Abstract:
An objective of the present invention is to avoid or alleviate corrosion of a contact part of an aluminum wire and a terminal which has a copper substrate as a base material. Provided is a bolt tightening terminal which connects to a wire comprising an aluminum core wire formed from an aluminum metal, said terminal comprising a wire connection part which is formed from a copper metal material and is continuous with an electrical contact part wherein a bolt hole is disposed, and to which the aluminum core wire is welded and electrically connected. The surface of the wire connection part is covered with a first metal such as nickel, and the surface of the electrical contact part is covered with a second metal such as tin. The first and second metals which are formed from different metals are selected from metals having, with hydrogen potential as a reference, a minus-side potential between the potential of aluminum which has a large ionization tendency and the said hydrogen potential, and the second metal has a smaller minus potential and a smaller ionization tendency than the first metal.
