<P>PROBLEM TO BE SOLVED: To prevent a break of a circuit or the like inside a card when inserting the electrostatically charged card. <P>SOLUTION: In this connector device, a bottom face of a card insertion part 21 is formed with an opening part 24, a part of a ground pattern 31 on a circuit board 30 is exposed inside the opening part 24, and a shortest distance A1 from a ground contact part 12a of the card 10 to the exposed part 34 is set to be shorter than a shortest distance A2 from a signal contact part 12c. Thereby, static electricity charged in the inserted card 10 is easily discharged from the ground contact part 12a to the exposed part 34 to prevent the break of the circuit or the like inside the card 10. <P>COPYRIGHT: (C)2003,JPO |
