Abstract
An electrical card connector (100) adapted for engaging with a CardBus (800) includes a housing (1) with a plurality of terminals (2) received therein, a shell (3), and an ejector device (4) mounted on the housing. The shell defines a rectangular opening (331) in a side plate (33) thereof and a stamped spring finger (332) connecting with a forward edge of the opening and extending backwardly. The spring finger has a pair of stop protrusions (3324) formed thereon for preventing an undesired card, such as a smart card (900), from inserting into the connector.
Claims12
An electrical card connector adapted to electrically engage with a predetermined mating card but block an undesired card from inserting thereinto, the undesired card having a thickness smaller than that of the mating card, comprising:
- a dielectric housing;
- a plurality of terminals assembled to the dielectric housing;
- a conductive shell shielding the dielectric housing;
- and
- a blocking device deflectably attached to the conductive shell, comprising a diverting portion with bevel guiding surface formed thereon and a hold-up portion, said guiding surface being adapted for leading the undesired card to move to be blocked by the hold-up portion.
An electrical card connector, adapted for electrically connecting with a desired card having a predetermined thickness but blocking an undesired card from inserting thereinto, the undesired card being thinner than the desired card, comprising:
- a dielectric housing with a plurality of terminals received therein;
- and
- a shell covering said dielectric housing, said shell having a spring finger integrally formed therewith, said spring finger having a guiding portion, a base portion connecting to said shell, and an intermediate portion interconnecting said guiding portion and said base portion, wherein said guiding portion and said base portion forms a V-shape relationship therebetween.
An electrical card connector for electrically connecting with a desired card having a predetermined first thickness but blocking an undesired card from inserting thereinto, the undesired card having a second thickness smaller than the first thickness, comprising:
- a dielectric housing with a plurality of terminals received therein;
- a space defined in front of said housing, with a first vertical dimension in compliance with the first thickness, for receiving the desired card in a front-to-back direction;
- and
- a spring finger disposed on one lateral side of said space, said spring finger including:
- an oblique actuation portion invading the space;
- and
- a stop protrusion invading the space and being actuated to move along with said actuation portion, said stop protrusion providing an effective stop face with a second vertical dimension in compliance with the second thickness;
- wherein
- when the desired card is inserted into the space, the actuation portion is outwardly deflected and the stop protrusion is associatively outwardly moved not to block insertion of said desired card;
- oppositely, when the undesired card is inserted into the space, the actuation portion can not be actuated and the stop protrusion stays in the space for blocking said undesired card.
