IC card with generally efficient circumferential shielding
First Claim
1. An I/O card assembly comprising:
- a main frame having two side walls, an elongated space extending horizontally along generally a centerline of each side wall in a front-to-end direction;
an auxiliary frame integrally formed in the main frame;
a pair of blocks positioned at front ends of the side walls, respectively;
a pair of socket supports positioned at rear ends of the side walls, respectively;
a PC board seated on said auxiliary frame;
a socket positioned between said pair of socket supports, said socket having contact tails conductively mounted at a rear end of the PC board;
an I/O connector positioned between said pair of blocks, said I/O connector having contacts tails conductively mounted at a front end of the PC board; and
a top cover and a bottom cover being attached to the main frame from the top and from the bottom, respectively, each cover having a main plate and a pair of shielding walls vertically extending, along opposite side edges of the main plane in the front-to-end direction, a distance which is generally one half of a height of the side wall of the main frame wherein said shielding walls of the top cover extend downwardly and said shielding walls of the bottom cover extend upwardly.

Abstract
An I/O card assembly (1) is provided having an insulative frame means (10, 40) sandwiched by a pair of generally similar conductive covers (50, 70). Each cover (50) includes a main plate (52) and two elongated side shielding walls (56) downward extending from two opposite sides of the plate (52) a first distance which is generally half of a height of the side wall (12) of the frame (10). A groove (18) horizontally extends along the center line of side wall (12) of the frame (10) for receiving both the hook sections (58) which are respectively inwardly formed at the outermost edges of the side shielding walls (56) of the top and the bottom covers (50, 70). Between the top and the bottom covers (50, 70), an internal PC board (80) is seated on the frame whereby two connectors (90, 100) are respectively soldered on two opposite end regions of the PC board (80) and respectively retained at two opposite ends of the main frame (10) and therefore, the PC board (80) and the two associated connectors (90, 100) are appropriately held in position in the card assembly (1) for mating with the corresponding electrical devices.
