Abstract
Abstract An IC card includes a circuit board having a generally planar substrate with at least one electrical component mounted thereon. A receptacle including terminals is mounted at an edge of the circuit board. A pair of cover panels sandwich the circuit board therebetween. At least one conductive ground clip holds the cover panels in assembled condition sandwiching the circuit board therebetween. A ground circuit on the circuit board engages the grounding clip. At least a portion of the grounding clip is exposed exteriorly of the IC card for engaging an appropriate ground on an appropriate mating electrical apparatus.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
170 words
In an IC card which includes a circuit board having a generally planar substrate with at least one electrical component mounted thereon, a receptacle including terminals mounted at an edge of the circuit board, and a pair of generally planar cover panels sandwiching the circuit board therebetween and leaving at least a mating face of the receptacle exposed for connection to an appropriate mating electrical apparatus, wherein the improvement comprises at least one elongated, channel-Shaped conductive grounding clip embracing adjacent side edge portions of the cover panels and including means for holding the cover panels in assembled condition, the cover panels including recessed areas at said edge portions for receiving leg portions of the grounding clip to maintain the leg portions generally flush with the planes of the cover panels, a ground circuit means on the circuit board for engaging the grounding clip, and at least a portion of the grounding clip being exposed exteriorly of the IC card for engaging an appropriate ground means on the mating electrical apparatus.
Claim 2
Dependent Claim
170 words
In an IC card which includes a circuit board having a generally planar substrate with at least one electrical component mounted thereon, a receptacle including terminals mounted at an edge of the circuit board, and a pair of generally planar cover panels sandwiching the circuit board therebetween and leaving at least a mating face of the receptacle exposed for connection to an appropriate mating electrical apparatus, wherein the improvement comprises at least one elongated, channel-Shaped conductive grounding clip embracing adjacent side edge portions of the cover panels and including means for holding the cover panels in assembled condition, the cover panels including recessed areas at said edge portions for receiving leg portions of the grounding clip to maintain the leg portions generally flush with the planes of the cover panels, a ground circuit means on the circuit board for engaging the grounding clip, and at least a portion of the grounding clip being exposed exteriorly of the IC card for engaging an appropriate ground means on the mating electrical apparatus.
Claim 3
Dependent Claim
19 words
In an IC card as set forth in claim 1, wherein said cover panels are fabricated of non-conductive material.
Claim 4
Dependent Claim
44 words
In an IC card as set forth in claim 1, wherein said channel-shaped grounding clip defines a bight portion joining said leg portions, and including a contact portion projecting inwardly of the bight portion for engaging the ground circuit means on the circuit board.
Claim 5
Dependent Claim
24 words
In an IC card as set forth in claim 3, wherein said contact portion is bifurcated for engaging opposite sides of the circuit board.
Claim 6
Dependent Claim
42 words
In an IC card as set forth in claim 3, wherein said grounding clip is a stamped and formed sheet metal component having a generally U-shaped cross section with said contact portion being bent inwardly at one end of said bight portion.
Claim 7
Dependent Claim
24 words
In an IC card as set forth in claim 1, including one of said grounding clips at each opposite side of the IC card.
Claim 8
Dependent Claim
148 words
In an IC card which includes a circuit board having a generally planar substrate with at least one electrical component mounted thereon and defining opposite sides and opposite ends thereof, a receptacle including terminals mounted at one end of the circuit board, and a pair of generally planar cover panels sandwiching the circuit board therebetween, wherein the improvement comprises: said cover panels are fabricated of non-conductive material, and a pair of elongated, channel-shaped conductive grounding clips are mounted at opposite sides of the circuit board and engaging ground circuit means thereon, the grounding clips embracing adjacent side edge portions of the cover panels and including means for holding the cover panels in assembled condition, wherein the cover panels include recessed areas at said edge portions for receiving leg portions of the channel-shaped grounding clips to maintain the leg portions generally flush with the planes of the cover panels.
Claim 9
Dependent Claim
148 words
In an IC card which includes a circuit board having a generally planar substrate with at least one electrical component mounted thereon and defining opposite sides and opposite ends thereof, a receptacle including terminals mounted at one end of the circuit board, and a pair of generally planar cover panels sandwiching the circuit board therebetween, wherein the improvement comprises: said cover panels are fabricated of non-conductive material, and a pair of elongated, channel-shaped conductive grounding clips are mounted at opposite sides of the circuit board and engaging ground circuit means thereon, the grounding clips embracing adjacent side edge portions of the cover panels and including means for holding the cover panels in assembled condition, wherein the cover panels include recessed areas at said edge portions for receiving leg portions of the channel-shaped grounding clips to maintain the leg portions generally flush with the planes of the cover panels.
Claim 10
Dependent Claim
46 words
In an IC card as set forth in claim 7, wherein each of said channel-shaped grounding clips defines a bight portion joining said leg portions, and including a contact portion projecting inwardly of the bight portion for engaging the ground circuit means on the circuit board.
Claim 11
Dependent Claim
28 words
In an IC card as set forth in claim 8, wherein said contact portion of each grounding clip is bifurcated for engaging opposite sides of the circuit board.
Claim 12
Dependent Claim
42 words
In an IC card as set forth in claim 8, wherein each grounding clip is a stamped and formed sheet metal component having a generally U-shaped cross section with said contact portion being bent inwardly at one end of said bight portion.
