Publication number: 20080113526Abstract: A convex portion which inclines in the direction of the short side is created by press work along the direction of the short side of a terminal, which extends longitudinally, from one end to the other end, and another terminal is pressed onto the convex portion with pressure and bonded together by electric resistance welding. At this time, because the convex portion inclines in the direction of the short side, the convex portion is not deformed and crushed; consequently, it is possible to ensure the area of the contact at which terminals are bonded together.Type: ApplicationFiled: November 12, 2007Publication date: May 15, 2008Applicant: Hitachi, Ltd.Inventors: Shinya NAKATANI, Shin Onose, Yasunori Odakura
