Electrical connector assembly with improved resisting structure to ensure reliable contacting between ground shields thereof

摘要

An electrical connector assembly (1) includes a header (300) and a receptacle (100) mateable with the header. The header includes a receiving space, a number of header contacts (32) and a header ground shield (33) located between the header contacts in adjacent two columns. The receptacle includes a number of contact modules (10) to be received in the receiving space. At least one of the contact modules includes an insulator (11), a receptacle ground shield (13) fixed in the insulator and a plurality of receptacle contacts (15) for mating with the header contacts. A mating portion (111) of the insulator includes a supporting rib resisting against the header ground shield in order to enhance mating force between the header ground shield and the receptacle ground shield when the receptacle is inserted into the receiving space of the header.
