Abstract
A frameless IC card is provided, with front and rear support structures that each includes an electrical connector, with a sheet metal cover mounted on the front and rear board supports without requiring a separate plastic frame to tie the components together. The rear support structure includes at least one rear connector (11', 12', FIG. 3) fixed to the circuit board rear end (104') and an end cap (16') at the rear of the IC card. The end cap has upper and lower flanges (126T, 126B) that form a recess therebetween that closely receives the rear of the rear connector housing to fix their relative vertical positions. The rear end cap has forwardly-extending legs (47, 48) at opposite sides, with each leg having a lug (51, 52) forming a rearwardly-facing shoulder (150) that fits into a cutout (53) at a side of the circuit board, to prevent forward movement of the connector and circuit board out of the rear end cap. Different types of IC cards have their circuit boards at different heights, which is accomplished by mounting the rear connector at different heights on the circuit board.
