Abstract:
An IC card comprising:a circuit board having a front end with laterally opposite sides, at least one laterally extending row of signal traces and at least one secondary ground trace;a front connector having a dielectric connector housing and at least one row of contacts mounted in said housing having contact tails engaging said signal traces;a ground plate lying on said connector housing and connected to said secondary ground trace;a metal enclosure including a sheet metal top cover lying over said circuit board, said top cover having a raised flat upper section with a forward lateral part, outer flanges extending along the opposite sides of said upper section, and an angular section interconnecting said upper section and said outer flanges and including a front angular part extending along said forward part of said upper section and providing a forward edge;said forward edge of said top cover being spaced rearwardly behind said ground plate and leaving a gap between them;a dielectric bridge element lying at the front end of said circuit board, said bridge element having a crossbeam and having laterally opposite sides fixed in position with respect to said laterally opposite sides of said circuit board, said dielectric bridge element extending forward from the forward edge of said top cover along a majority of the front-to-rear length of said gap; andsaid crossbeam having a laterally extending upward projection behind said front angular part supporting said forward part of said top cover upper section, said upward projection extending across substantially the entire width of said dielectric bridge between said laterally opposite sides of said circuit board.
