Connector assembly

A connector assembly comprising:

• a guide shielding cage having at least one insertion space positioned inside;
• a heat sink module comprising a heat dissipating member, a pressure applying elastic member, a lever member and a supporting elastic member, a bottom portion of the heat dissipating member having a thermal coupling portion, the pressure applying elastic member being provided at a side face of the heat dissipating member, the lever member having a pushed end which is used to be pushed and a pressure applying end which is used to downwardly apply a pressure to the pressure applying elastic member, the supporting elastic member upwardly and elastically supporting the heat dissipating member;
• and
• the heat dissipating member being capable of moving between a releasing position which is higher relative to the insertion space and an acting position which is lower relative to the insertion space and where the thermal coupling portion enters into the insertion space;
• when the pushed end of the lever member is subjected to be pushed by an external force to make the lever member rotated, the pressure applying end of the lever member downwardly applying a pressure to the pressure applying elastic member, so as to make the pressure applying elastic member downwardly push the heat dissipating member to the acting position, and make the heat dissipating member downwardly compress the supporting elastic member, the compressed the supporting elastic member being capable of providing a restoring force which makes the heat dissipating member restore to the releasing position when the external force is removed;
• when the pushed end of the lever member is not subjected to be pushed by the external force, the supporting elastic member upwardly supporting the heat dissipating member so as to make the heat dissipating member positioned in the releasing position, and the heat dissipating member making the pushed end of the lever member enter into the insertion space by that the pressure applying elastic member acts to the lever member.
