METHOD FOR CONNECTING POWER SUPPLY LINE AND SIGNAL LINE OF PRINTED BOARD, AND ELECTRIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To increase the mounting space of a board by decreasing the pin count of a connector for connecting power supply lines and signal lines. SOLUTION: Connectors 3 and 4 are clamped between a main board 1 and a subboard 2 and secured by means of a copper screw 5. Since a power supply IC and a load formed on the main board 1 and the subboard 2 are connected electrically through the connectors 3 and 4 and also connected through the screw 5 serving as a power supply line, pin count of the connectors is decreased.
