Abstract

A connector assembly (100) includes a first connector (200) and a second connector (300). The first connector includes a first housing (1) including a mating portion (10) opening in a first direction, a number of first contacts (2), a number of leads (3) electrically connecting with the first contacts in a second direction, and a first grounding member (5) including a first grounding shield (50) and a second grounding shield (52) electrically connecting with each other. The second grounding shield includes a second body portion (520) and a second vertical portion (526) extending from the second body portion in the first direction. The second connector includes a second housing (7), a number of second contacts (72), a second grounding member (9) enclosing the second housing, and a second pulling member (8). The second vertical portion of the second grounding shield exerts a pressing force on the second grounding member in the second direction and is circled by the second pulling member.
