Abstract: An electrical connector includes a latch for retaining an IC card. A card adaptor body receives the IC card. The adaptor body has a connector end including a pin header. A pair of opposed card side edge guides extend from the connector end and terminate adjacent an open end of the adaptor body. The IC card is inserted into the adaptor body and has a connector edge engaged with the pin header, a pair of opposed sides engaged with the side edge guides and a rear edge at the open end of the adaptor body. A retainer includes a flexible arm and a hook extending from the connector end into the open end. The hook is automatically engaged with the card rear edge when the card is inserted for retaining the card engaged with the pin header, and is movable out of engagement with the card rear edge to permit the card to be removed from the adaptor body.
