Liquid Cooling Module and Connector

A connector, comprising:

• a connector housing having a plurality of insertion cavities arranged side by side in a transverse direction of the connector housing;
• and
• a liquid cooling module including a plurality of liquid cooling plates and a plurality of flexible tubes, the liquid cooling plates are arranged in parallel in the transverse direction, each liquid cooling plate has an inner chamber accommodating a cooling liquid, the flexible tubes are connected between any two adjacent liquid cooling plates, the inner chambers of any two adjacent liquid cooling plates are connected together by the flexible tubes, the liquid cooling plates are connected via the flexible tubes and have an inlet pipe joint and an outlet pipe joint connected to their inner chambers, so as to form a cooling circuit from the inlet pipe joint to the outlet pipe joint, the liquid cooling module is installed on a top wall of the connector housing, a plurality of windows corresponding to the insertion cavities are formed on the top wall of the connector housing, and contact protrusions of the liquid cooling plates respectively protrude into the insertion cavities through respective windows, the contact protrusions thermally contact a plurality of mating connectors inserted into the insertion cavities.
