Sn PLATED COPPER ALLOY MATERIAL FOR TERMINAL CONNECTOR

摘要

PROBLEM TO BE SOLVED: To provide a fitting terminal having low insertion force (apparent friction coefficient) when fitting and electric characteristics (contact resistance) similar to those of a Sn plated material. SOLUTION: A Sn plated alloy material for a terminal connector has a remaining Sn plated layer being 0-0.3μm in thickness and a Sn oxide film being 10-300A (angstrom) in average thickness. The Sn plated copper alloy material is used in manufacturing at least either a male or female terminal.
