Abstract

An electrical receptacle assembly includes a metallic cage defining a receiving space therein, a receptacle connector unit is received in the receiving space. The receptacle connector unit includes a pair of mating ports. An middle heat transfer unit is located between the two mating ports in a vertical direction. The middle heat transfer unit includes a plastic thermal pad with a pair of heat pipes insert-molded on two sides. The pair of heat pipes extend through a rear wall of the cage and connect to a rear heat sink unit located behind the rear wall of the cage. An electrical plug module assembly equipped with a metallic case composed of the upper part and the lower part each having a heat sink structure unitarily formed on the exterior surfaces.

First claim

What is claimed is:

1. A receptacle connector assembly comprising:
a printed circuit board;
a panel disposed at front of the printed circuit board;
a pair of cages mounted on the printed circuit board and extending through the panel, the pair of cages arranged side by side with a gap therebetween, each of the cages defining a receiving space for receiving a plug module, each of the cages defining at least one side through hole in communication with the gap and the receiving space; and
a pair of receptacle connectors mounted on the printed circuit board and received in the cages, respectively;
wherein the panel defines at least one middle through hole in communication with the gap for air flowing.

2. The receptacle connector assembly as claimed in claim 1 , wherein there are a plurality of middle through holes arranges in a column.

3. The receptacle connector assembly as claimed in claim 1 , wherein there are a plurality of side through holes arranged in a plurality of rows and columns.

4. The receptacle connector assembly as claimed in claim 1 , wherein the panel further defines a plurality of additional through holes located surrounding outer sides of the cages, the plug module comprising a pair of heat sink structures located on exterior surfaces of top side and the bottom side respectively, the heat sink structures formed to allow airflow in communication with all of the through holes and the additional through holes.

5. The receptacle connector assembly as claimed in claim 1 , wherein the receptacle connector is lower than a top side of the cage to allow airflow to a rear side of the cage.
