BATTERY PACK AND ASSEMBLY METHOD FOR BATTERY PACK

摘要

PROBLEM TO BE SOLVED: To dispense with use of spot welding when fixing a lead plate inside a battery pack on a printed wiring board of a protection circuit board to eliminate scattering of spot dust and melting and scattering of solder due to spot welding completely. SOLUTION: A projecting part provided on a lead plate side is fitted and caulked in an insertion hole 34d provided on a printed wiring board 34b side or is pressed at the outer periphery of the insertion hole 34d due to shape of projecting part itself to fix the lead plate on the printed wiring board 34b of the protection cicuit board 34 so that structural fixation and electrical connection are securely performed.
