ABSTRACT:
An assembly for connecting an IC card to a printed circuit board includes a surface mounted connector and an ejector unit. The surface mounted connector has contacts arranged in an upper and a lower row at a narrow pitch to achieve a high degree of density of electronic components while maintaining high accuracy of contact positioning. Contacts are made by punching out from a metal sheet and have round contact sections for electrical connection with an IC card, termination sections with a portion for soldering connection to the printed circuit board, U-shaped retaining sections for insertion into contact holding openings of housing and supporting legs fitted in locking sections of the housing. The ejector unit is small but sufficiently strong and is simple to manufacture. It comprises a frame with left and right edges bent to form a guiding section wrapping around the side edges of the inserted IC card. Retaining members and a grounding contact for the card are also made by the same stamping operation.
