Holding device for cards with a low pin count bus interface

摘要

A method and apparatus for retaining an electronic function card in the receptacle of a host data processing system (host socket) is described. The present invention exerts a retention force on the card in addition to the frictional forces exerted on each of the connector contacts inserted into the host socket. By increasing the retention forces exerted on an electronic function inserted into a host socket, the chance of the card dislodging from the host socket during a mechanical shock event is reduced. The present invention also provides tactile and/or auditory feedback to the user to indicate when the card is fully inserted into the host socket. Further, a card extractor may be coupled to the retainer of the present invention. When disengaged, the card extractor will release the retention force on the card and the card may be easily removed from the host socket.
