Title:
CAPACITOR LEAD TERMINAL AND METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
WIPO Patent Application WO/2010/070938
Kind Code:
A1
Abstract:
Disclosed is a capacitor lead terminal that does not contain lead, in which the growth of whiskers can be prevented. The capacitor lead terminal is constructed by welding a metal wire (3), which forms a metal plating layer (6) that comprises mainly tin, to an aluminum wire (2) that is to be connected to a capacitor element. A hole (12) formed on an end face of the aluminum wire (2) has a first inner diameter part (13) that has an inner diameter (D1') that is roughly the same as the outer diameter (C) of the metal wire (3), and a second inner diameter part (14) that has an inner diameter (D2') that is bigger than the outer diameter (C) of the metal wire (3). The metal wire (3) is pressed through the second inner diameter part (14) and into the first inner diameter part (13) from the opening on the end face of the aluminum wire (2).
