CARD EDGE CONNECTOR SYSTEM

PROBLEM TO BE SOLVED: To prevent a contact of a connector from contacting a land of a printed circuit board until the insertion of the printed circuit board into the connector is completed, and to prevent the size of the printed circuit board from being fixed. SOLUTION: A projecting edge 21 parallel with the insertion direction is formed on the printed circuit board 20. The connector 10 is provided with rails 11 each having a groove 11a for advancing the projecting edge 21 along them. The rails 11 are horizontally moved when the projecting edge 21 is inserted. The contacts 12 in contact with the lands 22 of the circuit board 20 are connected to the rails 11, and horizontally opened and closed by gearing with the movement of the rails 11. Therefore, when the circuit board 20 is inserted into the connector 10, the rails 11 are horizontally opened by the projecting edge 21 of the circuit board 20 and the contacts 12 are also opened at the same time. Since the projecting edge 21 is advanced along the grooves 11a, the need of a guide for supporting the insertion of the circuit board 20 is obviated. COPYRIGHT: (C)2004,JPO
