COUPLING STRUCTURE OF METAL PLATE TO METAL SHAFT AND ELECTRODE STRUCTURE OF SEALED BATTERY |
摘要 |
<P>PROBLEM TO BE SOLVED: To provide a coupling structure A of a metal plate to a metal shaft, which has high coupling strength, excellent in positional accuracy and is inexpensive. <P>SOLUTION: The coupling structure A is constituted by force-fitting the metal shaft 5 into a blind hole 4 formed in a first surface 2 of the metal plate 1. The metal shaft 5 includes the body part 6 and a force-fitting end part 7. The force-fitting end part 7 includes a polygonal part 9, a small diameter part 10 and a taper-shaped guide part 11. The small diameter part 10 and the guide part 11 are arranged within the projected space in the axial direction X1 of the polygonal part 9. A necked space S1 is formed between the polygonal part 9 and the guide part 10. The polygonal part 9 causes the inlet edge part 41 of the blind hole 4 to deform plastically to the side of the second surface 3 and enters the inlet edge part 41. The metal plate 1 includes the plastically deformed part 12 which enters the necked space S1. <P>COPYRIGHT: (C)2013,JPO&INPIT |
