Shielded connector assembly with improved thermal management

Abstract

A connector assembly includes a guide shielding cage, an internal biasing heat sink and two lateral heat dissipating members. The guide shielding cage includes a cage body and a partitioning bracket provided in the cage body, the cage body has a top wall and two side walls, the partitioning bracket has an upper wall and a lower wall which together define an interior receiving space, and the partitioning bracket and the cage body together define an upper receiving space and a lower receiving space, each side wall of the cage body is formed with a side window which is communicated with the interior receiving space, the lower wall of the partitioning bracket is formed with a lower window which allows the interior receiving space to be communicated with the lower receiving space. The internal biasing heat sink is provided in the partitioning bracket and has an internal heat dissipating member, the internal heat dissipating member enters into the lower receiving space via the lower window. The two lateral heat dissipating members are respectively positioned outside the two side walls of the cage body, the two lateral heat dissipating members and the internal heat dissipating member are connected with each other by means of connecting structures which respectively pass through the side windows, the two lateral heat dissipating members is capable of moving with the internal heat dissipating member along the up-down direction.
