Description

Technical Field

[0001] The present invention relates to a connector housing assembly and a connector comprising the connector housing assembly. Background Art

[0002] In the prior art, to improve the heat dissipation of connectors with multiple layers of ports, a heat sink is typically installed on the top wall of each connector port. The heat sink protrudes into the port to thermally contact the mating connector inserted into the port. However, in some applications, heat dissipation through heat sinks alone is insufficient to achieve the required heat dissipation. Therefore, a liquid cooling plate is installed on the top wall of the connector's top-layer port. This liquid cooling plate is in thermal contact with the top of the heat sink on the top-layer port to further improve the heat dissipation of the top-layer port. However, the prior art lacks a liquid cooling plate to dissipate heat from the bottom-layer ports, resulting in the bottom-layer ports' heat dissipation performance failing to meet the required specifications.
