Abstract

An IC card is provided, of the type that has a cardbus shield (30) with a shield plate (132) mounted on the top of a front connector (12) and with shield tails (36) extending rearwardly and downwardly to secondary ground traces (50) on a circuit board (34), wherein the IC card includes a dielectric cardbus bridge with a crosspiece (100). The crosspiece supports the middle (104) of the front end (102) of the sheet metal top cover so it is held securely out of contact with the cardbus shield but lies above at least portions of the contact tails (130) that extend from the rear of the front connector to signal traces on the circuit board. The crosspiece is supported to lie over the circuit board closely behind the rear end (136) of the shield plate, with the crosspiece having a top cover support surface (112) on which the front end of the cover middle lies. The bridge has slots (110) that pass the shield tails and has an upward projection (152) at its front end that forms a rearwardly-facing shoulder (116) to abut the front edge of the middle of the top cover. The cardbus bridge has laterally opposite sides forming mounts (72, 74) that are each fixed to a corresponding side of the circ…
