PURPOSE:To obtain a structure which complies with a high-density mounting operation by a method wherein an auxiliary board is installed in parallel with a backboard of an enclosure which houses a unit composed of a printed circuit board, both boards are isolated by using a pin used also as a spacer and the pin is connected to a plug-in connector. CONSTITUTION:An auxiliary board 4b is installed in parallel with a backboard 4a, having many contact pins 5, of an enclosure which houses many units 2 composed of mounting printed circuit boards provided with a plug-in connector 6. The boards 4a and 4b are isolated by contact pins 8 used also as spacers. Tips of the pins 8 are connected to the connector 6. On the other hand, a terminal cable 11 is introduced into an interface connector 7 of the board 4b; and a connector arrangement structure for terminal line introduction use at an electronic device which complies with a high-density mounting operation is obtained. |
