Heat dissipation module and connector

A connector, comprising:

• a metal housing;
• and
• a heat dissipation module mounted on a top of the metal housing, comprising:
• a plurality of heat dissipation units arranged along a longitudinal direction of the heat dissipation module, each heat dissipation unit has a plurality of heat dissipation fins arranged at intervals along a transverse direction of the heat dissipation module, the heat dissipation fins of a first heat dissipation unit of a pair of adjacent heat dissipation units are each coupled with one of the heat dissipation fins of a second heat dissipation unit of the pair of adjacent heat dissipation units by a coupling structure, the heat dissipation fins of the first heat dissipation unit and the heat dissipation fins of the second heat dissipation unit are displaceable with respect to each other within a certain range;
• and
• a left frame connected to the heat dissipation fins of the one of the heat dissipation units disposed at a first end of the heat dissipation module in the longitudinal direction, and a right frame connected to the heat dissipation fins of the one of the heat dissipation units disposed at a second end of the heat dissipation module opposite to the first end in the longitudinal direction.
