Document Type and Number:
Japanese Patent JP2879739
Kind Code:
B2
Abstract:
PURPOSE:To reduce a contact resistance to a minimum while a welding strength of a connection between a lead wire and a terminal for external connection use is being maintained by a method wherein a part where a tip part of the strip-shaped lead wire extracted from a capacitor element has been folded back is placed on the terminal, for external connection use, which has pierced a sealing sheet and the part is welded by means of a laser. CONSTITUTION:A capacitor element is formed by winding an electrode foil. A strip-shaped lead wire 1 composed of aluminum or the like is connected electrically to the electrode foil by using a well-known means. The lead wire 1 is guided to the outside from one end face of the capacitor element. A sealing sheet 8 is formed by pasting a hard sheet 10 composed of a heat-resistant synthetic resin on an elastic body 9. A rivet part 4 at a terminal 3 protrudes from the other end face of the sealing sheet 8; a flat part 6 is formed at an end face of the rivet part 4. A tip part of the lead wire 1 is folded back at a definite distance; this folded-back part 2 is placed on the flat part 6 of the rivet part 4 at the terminal 3; a part where the lead wire 1 comes into contact with the terminal 3 is irradiated with a laser 11 in a direction perpendicular to a longitudinal direction of the lead wire 1; four welding points 7 are set.
