Electrical card connector assembly avoiding displacement of terminals

摘要

An electrical connector assembly comprises an IC card connector and a transition connector. The IC card connector includes a dielectric housing, a number of conductive terminals received in the housing, a grounding plate partially covering the housing, a pair of guiding rails and a card ejection mechanism. A mating board projecting from a mating face at a front end of the housing has a number of slots and grounding recesses in the surfaces thereof. The slots are uniformly spaced and located in top and bottom surfaces of the mating board. The slots extend through the housing from the mating face to a contacting face at a rear end of the housing. The grounding recesses are disposed in the top surface of the mating board and are alternatingly spaced between the slots. The conductive terminals are secured in the slots thereby avoiding deflection. A number of grounding fingers depending from a front edge of the grounding plate is received in the corresponding grounding recesses. The transition connector possesses a number of mating contacts and a mating cavity corresponding to the conductive terminals and the mating board. The mating contacts each have a curved end for engaging with a conductive terminal and an opposite end extending to a printed circuit board.
