  • Secondary Battery
    Publication number: 20130071728
    Abstract: A highly-reliable secondary battery is provided. The secondary battery is configured as below. A battery lid 1 is formed with a cylindrical projection 1a projecting toward an insulating member 3. The cylindrical projection 1a is secured to the insulating member 3 (a caulking portion 1A) by caulking so as to be bent outwardly at a position inside a projecting insertion hole 3b formed in the insulating member 3. A tip portion of a connecting pin 5 inserted through the pin insertion hole is caulked (a caulking portion 5d) to establish conduction between the connecting pin 5 and an external terminal 4 and to secure the external terminal 4, the insulating member 3, a gasket 2 and the connecting pin 5 to the battery lid 1. Thus, a terminal portion 15 does not turn.
