<P>PROBLEM TO BE SOLVED: To provide a terminal for sealed battery that suppresses internal resistance variation between an outer terminal and an inner terminal, is low-cost, and improves reliability as a battery. <P>SOLUTION: The terminal for sealed battery comprises an outer terminal 30 in a solid flat rivet shape and an inner terminal 27 in a hollow flat rivet shape; and a hollow shaft part 26 of the inner terminal 27 is inserted into a first insulating member 31, an aperture 15a bored in a sealing plate 15, and a second insulating member 32 while insulated from the sealing plate 15, and the outer terminal 30 has a columnar shaft part 29 inserted into the hollow shaft part 26 of the inner terminal 27 and pressure-crimped to form a diameter-swelling deformation part at an intermediate part of the columnar shaft part 29. The hollow shaft part 26 of the inner terminal 27 deforms in a shape conforming to the diameter-swelling deformation part of the columnar shaft part 29 of the outer terminal 30 to be pressed against the columnar shaft part 29 of the outer terminal 30, and a tip part 26b is curled along a curved surface 29a between a collar part 28 and the columnar shaft part 29 of the outer terminal 30. <P>COPYRIGHT: (C)2012,JPO&INPIT |
