Filed: 1996-02-09
Abstract: PROBLEM TO BE SOLVED: To provide a connector for a card which does not come into contact with a printed wiring board without enlarging a housing even at the time of being unexpectedly pressed down. SOLUTION: An insulation thin plate 15 integrated with the housing 10 is disposed between the printed wiring board 130 and the movable contact part 31 of the contact.
