It is to provide a sub-card board connector capable of secure grounding and also easy placement and removal of a card, a sub-card board, a modem sub-card, and a computer having this connector. In sub-card board connector 1 of the present invention, (1) first GND connections 11-1, 11-2 are placed on a surface facing the sub-card board 2 of the latches 7-1, 7-2 and when connecting the sub-card board to the connector, the sub-card board is grounded by having the first GND connections contact the first electrodes provided on the sub-card board; and/or (2) second GND connections 12-1, 12-2 are placed facing the sub-card board on a surface opposite to the latches of the latch supporting parts 6-1, 6-2 and when connecting the sub-card board to the connector, the sub-card board is grounded by having the second GND connections contact the second electrodes provided on the sub-card board. And this connector is incorporated in a computer.

DETAILED DESCRIPTION An object of the present invention is to solve the above-mentioned problem and provide a sub-card board connector capable of secure grounding and also easy placement and removal of a card, a sub-card board, a modem sub-card, and a computer having this connector.
The subject of the sub-card board connector of the present invention is a connector formed on a main-card board for connecting to the main-card board in a replaceable manner a sub-card board having various functions, the connector comprising: a connector body having an electrode pattern in contact with a terminal formed on an end face of the sub-card board; and latch supporting parts having latches from both ends of the connector body along the main-card board for setting the sub-card board on the connector body obliquely to the main-card board and, from that state, fixing the sub-card board by suppressing the reaction force in pressing the sub-card board against the main-card board so that it should be along the board.
In such a connector, (1) first GND connections are placed on a surface facing the sub-card board of the latches and when connecting the sub-card board to the connector, the sub-card board is grounded by having the first GND connections contact electrodes provided on the sub-card board; and/or (2) second GND connections are placed facing the sub-card board on a surface opposite to the latches of the latch supporting parts and when connecting the sub-card board to the connector, the sub-card board is grounded by having the second GND connections contact electrodes provided on the sub-card board.
Also, the sub-card board of the present invention is used for connecting with a connector of the above-mentioned structure, and in a state of the sub-card board placed on the connector, it has a first electrode provided in a position to contact first GND connections of the connector and/or a second electrode provided in a position to contact second GND connections.
In addition, a modem sub-card of the present invention comprises a sub-card board of the above-mentioned structure consisting of a card having a modem function
