A connector mechanism for connecting a board card is disclosed. The connector mechanism includes a circuit board whereon at least one metal contact is formed, and a connector installed on the circuit board. An end of the board card is for inserting into the connector. The connector mechanism further includes at least one signal transmitting component fixed on the other end of the board card and electrically connected to the board card. The at least one signal transmitting component includes at least one conductive clip for resiliently contacting the at least one metal contact on the circuit board as the end of the board card is inserted into the connector so as to electrically connect to the circuit board.
