Electronic card

摘要

An electronic card has a printed circuit board interposed between two card shields (7, 8) having edges. Tabs (9) on an edge of one shield engage recesses (10) on the edge of the other shield. The shields (7, 8) of the card provide high levels of rigidity, sufficient to exceed applicable bending and torsional resistance specifications to provide adequate rigidity. Also included is an I/O connector (2) which is shielded over its length and grounded without a separate ground contact. The tabs include an arcuate member having a medial oblique projection which engages a ledge of the other shield near the recess. Also included in an 'oil can' resistant shield in which a deep-draw recess is peripherally surrounded by a groove.
