BUS-BAR WELDING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To weld the pattern portions of bus-bars and tab terminal members with the bus-bars and the terminal members mounted on an insulating board after the bus-bars are divided and reduce the possibility that ruptures and cracks occur on welded sections welding by enabling of the pattern portions of the bus-bars and the tab terminal members of an electric junction box. SOLUTION: The pattern portions 201-203 of bus-bars are mounted on the holding face 320 of an insulating board 300 respectively, and positioning bosses 301 and through holes 302 are provided on the holding face 320 of the insulating board 300. Coupling holes 251, 151 provided at weld portions of the pattern portions 201-203 of the bus-bars and the tab terminal members 100 are coupled with the positioning bosses 301 for positioning, and the portions of the pattern portions 201-203 of the bus-bars and the tab terminal members 100 facing the through holes 302 are welded.
