Connector assembly with heat sink mounted on a shielding cage

A connector assembly comprising:

• a guiding shield cage having a top wall and an inserting passageway positioned in an interior of the guiding shield cage, the top wall having a window communicated with the inserting passageway;
• and
• a heat sink module provided to the guiding shield cage, the heat sink module comprising:
• a heat sink having a thermal coupling portion which is positioned to a bottom portion of the heat sink and a force applying spring acting portion which extends front and rear;
• a force applying spring having an elastic arm and a bottom arm which extend front and rear, the elastic arm being positioned above the bottom arm and being used to downwardly act on the bottom arm, the bottom arm being used to downwardly act on the force applying spring acting portion of the heat sink;
• a rotating member having a first rod and a second rod, the first rod being used to extend into the inserting passageway, and the second rod being used to act on the elastic arm of the force applying spring;
• and
• a supporting spring elastically upwardly supporting the heat sink, wherein:
• the rotating member is capable of rotating between a first position and a second position, the heat sink is capable of moving between a third position in which the heat sink is positioned in an upward position and a fourth position in which the heat sink is positioned in a downward position,
• when the rotating member is in the first position, the first rod extends into the inserting passageway, and the heat sink is supported in the third position by the supporting spring, and
• when the rotating member is the second position, the first rod extends away from the inserting passageway, and the second rod of the rotating member acts on the elastic arm of the force applying spring and brings the bottom arm to move downwardly on the force applying spring acting portion of the heat sink so as to position the heat sink in the fourth position.
