SHIELDED ELECTRICAL CONNECTOR WITH GROUND PINS EMBEDED IN CONTACT WAFERS

摘要

An electrical connector assembly includes a receptacle and a plug. The receptacle includes a housing defining two vertical stacked mating slots and a plurality of wafers loaded in the housing. Each wafer includes an upper pair and a lower pair of contacting portions, the upper pairs and the lower pairs of the wafers expose to the slots respectively. Each of the wafers further defines a ground contact with a contacting portion between the upper pair and lower pair of the contacting portions. The plurality of wafers includes pairs of differential signal wafers and ground wafers which are arranged in an alternating sequence in the connecting housing. The plug includes two card edges and a ground plate with a row of contacting pin between the card edges. The contacting pins of the ground plate touch with pairs of ground contacts formed with two adjacent ground contacts in two adjacent wafers.
