Abstract

Abstract This invention is directed to a fully shielded printed circuit (PC) card holder, that may be readily "snapped" into the assembly, or disassembled, as the case may be. The holder is intended to receive a PC card, where at least one end of the card is adapted to be electrically connected to an I/O type connector. The holder comprises a generally rectangular bottom cover member formed of a conductive material, corner supports integrally molded to the bottom cover member at the respective corners thereof, where each support includes a lower flange portion to which the bottom cover member is exposed. Further, a generally rectangular upper cover member is provided where the periphery thereof includes a downwardly extending flange adapted to engage the lower flange portion in electrical contact with the bottom cover member over a substantial portion of the periphery thereof. In the assembled condition, the holder provides continuous shielding against distortion of data signals between the PC card and the I/O type connector.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 130 words
A shielded printed circuit (PC) card holder for receiving a PC card, where at least one end of said card is adapted to be electrically connected to an I/O type connector, said holder comprising a rectangular bottom cover member formed of a conductive material, corner supports integrally molded to said bottom cover member at the respective corners thereof, where each said support includes a lower flange portion to which said bottom cover member is exposed, and a rectangular upper cover member whose periphery includes a downwardly extending flange adapted to engage said lower flange portion in electrical contact with said bottom cover member over a major portion of the periphery thereof, whereby to provide continuous shielding against distortion of data signals between the PC card and said I/O type connector.
Claim 2
Dependent Claim 130 words
A shielded printed circuit (PC) card holder for receiving a PC card, where at least one end of said card is adapted to be electrically connected to an I/O type connector, said holder comprising a rectangular bottom cover member formed of a conductive material, corner supports integrally molded to said bottom cover member at the respective corners thereof, where each said support includes a lower flange portion to which said bottom cover member is exposed, and a rectangular upper cover member whose periphery includes a downwardly extending flange adapted to engage said lower flange portion in electrical contact with said bottom cover member over a major portion of the periphery thereof, whereby to provide continuous shielding against distortion of data signals between the PC card and said I/O type connector.
Claim 3
Dependent Claim 31 words
The shielded PC card holder according to claim 1, wherein said molded bottom cover member and said frame includes at least one transverse support member against which said PC card lies.
Claim 4
Dependent Claim 32 words
The shielded PC card holder according to claim 1, wherein adjacent said corner supports are joined by rails, and said rail include a tapered edge to facilitate the assembly of said holder.
Claim 5
Dependent Claim 22 words
The shielded PC card holder according to claim 3, wherein said rails include a plurality of recesses for receiving a disassembly tool.
Claim 6
Dependent Claim 29 words
The shielded PC card holder according to claim 1, including a grounding tab internal with said upper cover member for electrically engaging corresponding grounding traces on said PC card.
Claim 7
Dependent Claim 38 words
The shielded PC card holder according to claim 1, wherein said downwardly extending flange is in a flexed state when the holder is assembled, whereby to provide a constant contact force between said bottom and upper cover members.
