The contact portion 3c of the signal connector terminal 3 then comes into contact with the corresponding contact terminal portion 6a of the card 6, and when the card is ejected, When the other end side of 6 is lifted up diagonally, first, the contact portion 3c of the signal connector terminal 3 separates from the corresponding contact terminal portion 6a of the card 6, and then the power source and the ground terminal Since the contact portion 2c of the connector terminal 2 is formed so as to be separated from the corresponding contact terminal portion 6a of the card 6, the connection between the card 6 and the connector terminals 2 and 3 is simple. It is possible to define the sequence operation.

By thus defining the sequence operation at the time of connection, an electronic circuit such as an integrated circuit (IC) built in the card 6 is supplied to a non-standard power supply signal from a load circuit unit such as an external electric device. Even when noise such as power supply noise is transmitted, unnecessary signals can be avoided to the ground pattern of the external device through the contact portion 2c of the power supply and ground connector terminal 2, and thus the card 6 can be prevented. Since a built-in electronic circuit can be protected and only a pure signal without power supply noise can be transmitted to the contact portion 3c of the signal connector terminal 3, a reliable card connector device is provided. It is something that can be done.
