Card connector with card-ejecting device

A card connector adapted for insertion of a card therein, the card having a front end and a rear end, said connector comprising:

• an elongated base plate having a first side surface, a front end, a rear end, a left side, a right side, and an accommodating groove that is formed in said first side surface of said base plate and that extends from said front end of said base plate to said rear end of said base plate, said groove having an open front end and a closed rear end and being adapted to receive the card therein in such a manner that the card is disposed at a retracted position, where the front end of the card extends from said open front end of said groove and where a space is present between the rear end of the card and said closed rear end of said groove;
• a card-ejecting device adapted to push the card outwardly relative to said groove to an extended portion in a longitudinal direction of said base plate when the front end of the card is pressed inwardly within said groove to move the rear end of the card to said closed rear end of said groove, and is subsequently released;
• and
• a retainer for retaining said card-ejecting device on said base plate;
• wherein said card-ejecting device includes:
• a slide slot formed in said right side of said base plate and extending along length of said base plate;
• a movable member, which is formed with an integral positioning element that is adapted to abut against the rear end of the card so as to move said movable member and the card synchronously when the card is pressed inwardly relative to said base plate, said movable member being retained at a first position, where the card is disposed at the retracted position, and being moved, when the front end of the card is pressed inwardly relative to said base plate to move the rear end of the card to said closed rear end of said groove and is subsequently released, to a second position, where the card is disposed at the extended position where the front end of the card can be pressed inwardly once again relative to said base plate to move the rear end of the card to said closed rear end of said groove, and subsequently released, thereby biasing the card to the retracted position by means of said card-ejecting device, said movable member being disposed slidably within said slide slot and being slidable relative to said base plate in the longitudinal direction of said base plate, said movable member being formed with an integral first resilient arm;
• a spring disposed between said movable member and said base plate for biasing said movable member to move forward on said base plate;
• a link rod having a front end that is connected pivotally to said movable member, and a rear end with an integral tongue that extends perpendicularly therefrom, said first resilient arm of said movable member pressing against said link rod, thereby biasing said link rod to rotate in a predetermined direction;
• and
• a guide slot formed in said first side surface of said base plate for receiving said tongue of said link rod slidably therein, said guide slot having an annular slot portion and a longitudinal front slot portion that extends forward from a portion of said annular slot portion and that has a rear end, and a closed front end, said tongue of said link rod being biased by said spring to said front end of said longitudinal front slot portion when said movable member is located at said second position, said annular slot portion having
• a generally straight left slot portion extending rearward and leftward from said rear end of said longitudinal front slot portion and having a rear end,
• a generally V-shaped rear slot portion extending rightward from said rear end of said left slot portion and having a left end, a right end, and a curved middle portion that is located midway between and in front of said left and right ends, said tongue of said link rod being disposed at said curved middle portion when said movable member is located at said first position, and
• a generally straight right slot portion extending forwardly and rightward from said right end of said rear slot portion to said rear end of said longitudinal front slot portion, said tongue being movable from said curved middle portion of said V-shaped rear slot portion to said right end of said V-shaped rear slot portion by pressing inward the front end of the card so as to move the rear end of the card to said closed rear end of said groove, after which said tongue is biased, upon release of the card, by said spring and said first resilient arm to said front end of said longitudinal front slot portion via said right slot portion, said tongue being movable from said longitudinal front slot portion to said left end of said V-shaped rear slot portion via said left slot portion by pressing inward the front end of the card so as to move the rear end of the card to said closed rear end of said groove, after which said tongue is biased, upon release of the card, by said spring and said first resilient arm to said curved middle portion of said V-shaped rear slot portion.
