PURPOSE:To provide a terminating circuit connecting structure to connect the terminating circuit with a mother board for line impedance matching of the mother board. CONSTITUTION:Press fit connectors 2 are arranged regularly on a surface of a mother board 1 and daughter boards 11 are press fit to the press fit connectors 2. Lead pins 3 of the press fit connector 2 are projected through the mother board 1. A terminating circuit module 4 consists of an outer frame, a rigid board and a flexible board. The rigid board is mounted with socket pins that engage with the lead pins 3. The socket pins 7 are connected through chip resistors of terminating resistors with power supply voltage and ground voltage. By engaging the socket pins 7 of the terminating circuit module 4 with the lead pins 3, the line impedance matching of the mother board 1 is done through the socket pins 7. |
