Abstract

A connector is disclosed that includes housing positioned within a cage, the connector having a first port and second port that are vertically spaced apart. A thermal management module is positioned between the two ports. The thermal management module directs thermal energy from one or both ports out a rear wall of the connector. A heat sink can be coupled to the thermal management module to improve thermal dissipation.

First claim

We claim:

1. A connector, comprising:
a housing including a first card slot and a second card slot, the card slots spaced apart, the housing supporting a plurality terminals, the terminals including contacts positioned in the first and second card slots;
a cage positioned around the housing and having a rear wall, the cage defining a first port and a second port, the first port aligned with the first card slot and the second port aligned with the second card slot; and
a thermal management module with a nose and a rear, the nose positioned between the first and second port and including a first thermal interface configured to extend into the first port and configured to engage a mating port and a second thermal interface configured to extend into the second port and configured to engage a mating port, the thermal management module including a heat pipe that extends from the nose to the rear, the rear extend rearward of the rear wall, wherein the heat pipe is configured to direct thermal energy from the nose to the rear.

2. The connector of claim 1 , further comprising a heat sink that is thermally coupled to the rear portion.

3. The connector of claim 2 , wherein the heat pipe extends out of an aperture in the rear wall.

4. The connector of claim 3 , wherein the cage has a first wall and a second wall and a top wall and the heat sink is configured to be positioned within a region defined by the first, second and top wall.

5. The connector of claim 4 , wherein the first thermal interface includes a plurality of fingers.

6. The connector of claim 5 , wherein the cage further includes an insert that helps define the first and second port, the thermal management module supported by the insert.

7. A connector with a mounting face, comprising:
a housing with a mounting face, the housing including a first card slot and a second card slot, the card slots spaced apart, the housing supporting a plurality of terminals that extend from a mounting face to the card slots;
a cage positioned around the housing and having a rear wall, two side walls and a top wall;
an insert positioned in between the two side walls, the insert and the cage defining a first port and a second port, the first port aligned with the first card slot and the second port aligned with the second card slot; and
a thermal management module positioned between the two ports, the thermal management module including a first thermal interface that extends into the first port and configured to engage a mating port and further including a heat pipe that is thermally coupled to the thermal interface, the heat pipe extending out the rear wall of the cage.

8. The connector of claim 7 , wherein the thermal management module includes a second thermal interface that extends into the second port, the second thermal interface thermally coupled to the heat pipe.

9. The connector of claim 8 , wherein the heat pipe is a first heat pipe and the thermal management module includes a second heat pipe that extends out the rear wall of the cage.

10. The connector of claim 9 , wherein the first heat pipe and the second heat pipe extend on opposite side of the housing.
