ABSTRACT:
A multi-pin connector for connecting a signal line on a backboard side and a signal line on a daughter board side has open pins where the signal lines are not connected. In order to prevent transmission loss on the signal lines caused by these open pins, terminating resistances are connected to both ends of the open pins, and ends of the terminating resistances opposite to the open pins are connected to ground or to a power supply.
