Abstract
The rear of a thin IC card is provided with a jack (42A, 42B, FIG. 4) that can receive a multi-contact audio type plug (40) having a diameter that is more than half the thickness of the card. The circuit board has a slot (60) that opens into the rear of the card. A U-shaped insulative block (80) is mounted on the card, with the opposite arms of the block lying at opposite sides of the board slot. Sheet metal contacts are mounted on the block and project into the slot in the circuit board, with each contact having a vertically-extending plug-engaging part (120) lying in the circuit board slot. The IC card includes a housing with a rear end cap (140) having a largely cylindrical passage (142A, 142B) that guides an audio-type plug into the slot in the circuit board to engage the contacts thereat. The end cap is constructed to form a rearward extension of the card that projects rearward of a card-receiving host slot, to enable a wide plug handle to be inserted against the rear of the end cap.
