Patent number: 6478591Abstract: An electrical card connector (5) includes a shell (1), an insulative body (2) covered by the shell, a plurality of terminals (3) received in the body, and a card ejection mechanism (4) mounted in the body. The card ejection mechanism includes a slide block (40), an elastic element (42), a push bar (44), and an elastic piece (46). When an electrical card (6) is inserted into the connector, the slide block is pushed inwardly until it is engaged by the elastic piece. The card is thus securely retained in the connector, with the elastic element being compressed. To eject the card, the push bar is manually pushed inwardly. The push bar gradually forces the elastic piece away from the slide block. The elastic element decompresses, pushing the slide block back out.Type: GrantFiled: October 29, 2001Date of Patent: November 12, 2002Assignee: Hon Hai Precision Ind. Co., Ltd.Inventor: Jen Jou Chang
