Card connector having overstroke for card mounting position

Claim 1

A card connector, comprising: a housing having a card insertion port for receiving a card at one end of which plural contact terminal parts are juxtaposed; plural connector terminals placed at one end of the housing, each connector terminal being connected with each of the contact terminal parts of the card; a sliding member movable in a card insertion direction; a heart-shaped lock cam; and an energizing member for energizing the sliding member in an ejection direction, wherein the housing is constructed such that, while the card is disposed inside the card insertion port, overstroke of the card in the card insertion direction from a card mounting position is possible, wherein the connector terminals are retained in the form of cantilever beams, at least one of the connector terminals being provided with a first contact part and a second contact part which are formed by dividing a tip of the connector terminal into two branches, both of which are in contact with the corresponding contact terminal part, and which are disposed at different positions in the card insertion direction, and wherein when the card is inserted or ejected, as long as the card is further subjected to overstroke in the card insertion direction from the card mounting position, at least one of the first contact part and the second contact part is formed so as to always contact the corresponding contact terminal part; wherein the first contact part is formed longer in the card insertion direction than the second contact part and placed on a side of the card insertion port; wherein a relationship of L>A>S−B is satisfied where the distance between the first contact part and the second contact part is A; the distance between a contact position of the first contact part with the contact terminal part, and an edge of the contact terminal part at the card insertion port is B when the card is in a mounting position; the length of the contact terminal part in the card insertion direction is L; and an overstroke amount of the card is S; wherein the sliding member moves in the card insertion direction together with the card; and wherein after the card over-strokes against an inserting and fitting position of the card, the sliding member is locked at the heart-shaped lock cam and the card is held at the mounting position.
