Abstract

A connector system includes a plurality of housing mounted on a circuit board and a plurality of cages are provided, each cage enclosing one of the housings, each of the cages including a front face that defines a first port, the cages being spaced apart a predetermined distance. A thermal washer is positioned around the cages, the thermal washer including a front portion and a main portion with air apertures that allow air to flow through the thermal washer and along a gap between the cages.

First claim

We claim:

1. A connector system, comprising:
a circuit board;
a plurality of housing mounted on the circuit board, the plurality of housings arranged side by side;
a plurality of cages, each one of the plurality of cages enclosing one of the plurality of housings, each of the cages including a front face that defines a first port and further including an electromagnetic interference (EMI) gasket that extends around a perimeter of cage near the front face, wherein the plurality of cages are spaced apart a predetermined distance;
a thermal washer positioned around the plurality of cages, the thermal washer including a front portion and a main portion, each of the front and main portions including air apertures, the main portion being a first width that is slightly less than the predetermined distance, the main portion engaging the EMI gasket, and the front portion having a second width that is slightly greater than the predetermined distance, the front portion engaging the front face so as to prevent, in operation, the front portion of the thermal washer from being pressed past the front face.

2. The connector system of claim 1 , further comprising a bezel that extends around the front faces of the plurality of cages, the thermal washer having a sealing face that is configured to press against the bezel.

3. The connector system of claim 2 , further comprising a seal that is positioned between the sealing face and the bezel, the seal being compressed between the sealing face and the bezel.

4. The connector system of claim 3 , wherein the housings and the cages are configured to each provide two ports, one of the two ports stacked over the other of the two ports.

5. The connector system of claim 4 , wherein the EMI gasket is a plurality of fingers and the main portion causes at least some of the fingers to deflect.

6. The connector system of claim 5 , wherein the sealing surface is positioned rearward of the main portion so that the front portion is arranged on the front face, the main portion is recess rearward and the sealing surface is further recessed rearward compared to the main portion.
