Disclosed is an electronic card comprising a printed circuit board interposed between card shields having edges. Tabs on an edge of one shield engage recesses on the edge of the other shield. The jointed shields of the card provided high levels of rigidity, sufficient to exceed applicable bending and torsional resistance specification. Adequate rigidity is thereby provided. Also included is an I/O connector grounded without a separate ground contact and shielded over its length. The tabs include an arcuate member having a medial oblique projection which engages a ledge of the other shield near the recess. The electronic card of the invention also comprises a printed circuit board interposed between card shields having edges. Tabs on the edges of one shield engage recesses on the edge of the other shield. Adequate rigidity is thereby provided. A frame bar is interposed between the shields. Also included is an I/O connector grounded without a separate ground contact and shielded over its length. Also included in an "oil can" resistant shield in which a deep-draw recess is peripherally surrounded by a groove.
