Title:
ELECTRIC CONTACT FOR BREAKER, AND MANUFACTURING METHOD THEREOF
Document Type and Number:
Japanese Patent JP2014232617
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an electric contact for a breaker in a junction structure in which an activator such as a flux or a shape is not limited and which is not influences by the risk of transferring a tool shape to a joined material, the shape of a joined body or the presence/absence of ductility in joining heterogeneous metal materials of the electric contact, and a manufacturing method thereof.SOLUTION: The electric contact comprises a junction 10A-a which is formed by interposing a plastic flowable intermediate metal layer 3 between a contact 1A and a base metal 2A of which the hardness is lower than the contact 1A. The junction 10A-a is provided while being recessed, just by a predetermined depth (i), from a support enclosure part surface 2A-b of a support enclosure part 2A-a supporting and enclosing the junction 10A-a. A width direction dimension B of the supporting and surrounding part 2A-a is greater than a width W of the junction 10A-a.
