Abstract
Abstract An electronic card which includes 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 provide high level 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.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
129 words
In an electronic card comprising a printed circuit board assembly interposed between card shields having edges wherein the improvement comprises resilient tabs on the edges of one shield that engages recesses on the edge of the other shield and each of said tabs comprises an arcuate member having an oblique projection, and each of the recesses has an angled end which engages the arcuate member of one of said tabs, and each of the tabs has a tab length and each of the tabs is resilient over about its entire tab length, and the card has a card length and the tabs have a cumulative tab length and the cumulative tab length at least about 50% of the card length, wherein said card resists bending forces and torsional forces.
Claim 2
Dependent Claim
129 words
In an electronic card comprising a printed circuit board assembly interposed between card shields having edges wherein the improvement comprises resilient tabs on the edges of one shield that engages recesses on the edge of the other shield and each of said tabs comprises an arcuate member having an oblique projection, and each of the recesses has an angled end which engages the arcuate member of one of said tabs, and each of the tabs has a tab length and each of the tabs is resilient over about its entire tab length, and the card has a card length and the tabs have a cumulative tab length and the cumulative tab length at least about 50% of the card length, wherein said card resists bending forces and torsional forces.
