Abstract: A connector assembly includes a shielding cage, a partitioning assembly and a plurality of supporting members. The shielding cage has a plurality of walls and an internal space defined by the plurality of walls, the plurality of walls includes two side walls. The partitioning assembly is assembled to the two side walls of the shielding cage and partitions the internal space into two inserting chambers arranged up and down, the partitioning assembly includes two partitioning plates which are arranged up and down and two grounding elastic pieces which are respectively assembled to front ends of the two partitioning plates, the two partitioning plates are spaced apart from with each other by a preset interval to together constitute an air flow passageway and a front end opening positioned to a front end of the air flow passageway. The plurality of supporting members are supported between the two partitioning plates.
