Abstract:
An electrical card connector assembly for providing connection between a pair of electrical cards and a mother board, comprising:an upper and a lower stacked shielded header connectors, each header connector including an insulative housing defining a space for receiving a corresponding electrical card;a row of upper terminals and a row of lower terminals retained in the housing of each of upper and lower header connectors for engaging with a corresponding electrical card, each terminal being retained in a corresponding housing and having a mounting portion and a mating portion at opposite ends thereof, the mounting portion having a narrower cross-section than the part retained in the housing, the mounting portion of each upper terminal being disposed to be offset a distance relative to the mating portion of the same upper terminal toward one lengthwise side of the housing that the upper terminal is retained in, and the mounting portion of each lower terminal being disposed to be offset a distance relative to the mating portion of the same lower terminal toward an opposite lengthwise side of the the housing that the lower terminal is retained in, whereby tail portions of the upper and lower terminals in each housing are aligned in a same row and have a pitch between each other equal to half a distance of the pitch between the mating portions of the same terminals;a first grounding plate mounted to a top surface of the lower header connector and having a plurality of grounding fingers;a second grounding plate mounted to a top surface of the upper header connector and downwardly extending to electrically contact the first grounding plate;a spacer defining a plurality of rows of passageways accommodating the mounting portions of the upper and lower terminals and a row of passageways to accomodate the grounding fingers of the first grounding plate between the rows of passageways accommodating the mounting portions of the upper and lower terminals; anda receptacle connector mounted on a mother board and connected with the spacer, the receptacle connector including a plurality of mating contacts engaged with the terminals of the header connectors and a metal plate in contact with the grounding fingers of the first grounding plate.
