Electrical connector assembly with improved liquid cooling plate

An electrical connector assembly, comprising:

• an electrical connector comprising an insulating body, a plurality of conductive terminals and a metal shielding cage covering the insulating body;
• the insulating body comprising a mating surface and a mating slot extending through the mating surface;
• each conductive terminal comprising a contact portion extending into the mating slot;
• the metal shielding cage comprising a receiving cavity communicating with the mating slot;
• the receiving cavity and the mating slot being configured to jointly receive a mating plug along a mating direction;
• and
• a liquid cooling plate at least partially covering the metal shielding cage, the liquid cooling plate comprising a cooling liquid inlet and a cooling liquid outlet;
• the liquid cooling plate comprising a liquid cooling base plate and a cover plate fixed to the liquid cooling base plate;
• the liquid cooling base plate comprising a first inlet flow channel, a second inlet flow channel and an outlet flow channel;
• the first inlet flow channel and the second inlet flow channel being fluidly arranged in parallel, and communicate with the cooling liquid inlet;
• the first inlet flow channel and the second inlet flow channel converging into the outlet flow channel which communicates with the cooling liquid outlet;
• wherein the liquid cooling base plate comprises a first surface and a recessed portion recessed from the first surface;
• the first inlet flow channel, the second inlet flow channel and the outlet flow channel are located in the recessed portion;
• and
• wherein the cover plate is installed in the recessed portion;
• and the cover plate comprises a second surface which is flush with the first surface.
