Grounding clip structure of I/O card

A semi-finished pre-assembly of an I/O card for use with a computer, comprising:

• a rectangular frame;
• a bottom cover attached to said frame from the bottom;
• and
• a top grounding clip for grounding circuit traces of a top surface of an internal PC board which is adapted to be attached to said frame in a later time, said top grounding clip being pre-assembled to said frame before said PC board is ready to mount on said frame, wherein said grounding clip substantially constitutes no obstacle for loading said PC board onto the frame from the top side of the frame, wherein said frame includes a pair of opposite side arms one of which said top grounding clip is seated on, and said top grounding clip includes a defomable deflected engaging tang whereby a front end of said engaging tang does not extend out of an inner edge of said frame for allowing top-loading of said PC board onto the frame when no top cover is attached to said frame, but extends into an interior of said frame to mechanically and electrically engage a grounding pad on a surface of the PC board when the top cover is attached onto the frame from the top and mechanically presses down said engaging tang.

An I/O card assembly for use with a computer, comprising:

• a rectangular frame sandwiched between a top cover and a bottom cover;
• at least a connector positioned at one end of said I/O card assembly to be an interface with the computer;
• a PC board disposed on the frame within the I/O card assembly, said PC board having circuit traces on a top surface and a bottom surface thereof for electrically connecting with said connector;
• at least a bottom grounding clip for grounding said circuit traces on the bottom surface of the PC board, being attached to the frame wherein said grounding clip includes a main body from which an upwardly engaging tang integrally extends inwardly in order to abut against a corresponding grounding pad of said circuit traces on the bottom surface of the PC board, and from which at least one tongue extends for conductive engagement with a corresponding portion of at least one of the covers, and wherein said main body of said grounding clip has generally a U-Shaped configuration including a top wall, a bottom wall and a side wall intermediating therebetween, said engaging tang extending from the bottom wall, said tongue extending from one of the top and bottom walls, and at least a retaining projection extending from one of the top and bottom walls.
