Electrical connector assembly for pc cards

An electrical connector assembly which provides an interconnection between a pc card and a printed circuit board, the pc card including a plurality of receptacle contacts at one edge thereof and the printed circuit board including a plurality of circuit traces thereon, comprising:

• a header connector subassembly including an elongated body for receiving the edge of the pc card, with the body defining opposite ends,
• a plurality of header terminals mounted in the body in an array between the opposite ends of the elongated body and with pin portions for mating with the receptacle contacts of the pc card, and
• a generally planar grounding shroud extending longitudinally between the opposite ends of the array of header terminals and including a ground tail projecting generally perpendicular to the planar shroud at each end thereof;
• and
• a board-mounted connector subassembly including an elongated housing adapted for mating with the elongated body of the header connector subassembly, the housing defining opposite ends thereof,
• a plurality of socket terminals mounted on the elongated housing in an array between the opposite ends thereof for mating with the header terminals of the header connector subassembly and with socket tail portions adapted for interconnection with the circuit traces on the printed circuit board, and a ground terminal at each opposite end of the elongated housing for receiving the ground tails at opposite ends of the shroud and with a solderable portion adapted for interconnection to a ground circuit on the printed circuit board.

An electrical connector assembly which provides an interconnection between the contacts of a pc card and the circuit traces of a printed circuit board, comprising:

• a header connector subassembly including a two-part body with each body part adapted for receiving one of a pair of stacked pc cards,
• a plurality of header terminals on each body part with contact portions adapted for interconnection with the contacts of the respective pc card received by the body part,
• a first grounding shroud positioned between the two body parts and extending about said header terminals and including a downwardly extending grounding terminal portion, and
• a second grounding shroud on the outside of one of the body parts about the header terminals therein and including a downwardly extending grounding terminal portion;
• and
• a board-mounted connector subassembly including a housing adapted for mating with the two-part body of the header connector subassembly,
• a plurality of socket terminals on the housing for mating with the header terminals on both body parts of the header connector subassembly with socket tail portions adapted for interconnection with the circuit traces on the printed circuit board, and
• ground terminals on the housing for mating with the grounding terminal portions of the first and second shrouds and with solderable portions adapted for interconnection to ground circuit traces on the printed circuit board.
