SECONDARY BATTERY OF USING CENTER PIN AS CONNECTION TERMINAL

摘要

PURPOSE: A secondary battery using a center pin as a connection terminal is provided to reduce the number of components because a separate electrode terminal is unnecessary and to maintain safety through constant voltage measurement. CONSTITUTION: A center pin for a secondary battery includes 2 unit members which are mutually separated due to a semicircular structure at a horizontal side. The members are faced with each other to form a circular form. A vertical path is formed in each member. The vertical path has a semicircular structure at a horizontal side. The center pin for a secondary battery has an input-output terminal by being connected to the lower end of the inner side of a metal can(150).
