Abstract

A connector includes a cage that surrounds a housing. The cage defines two vertically spaced apart ports. A chamber is positioned between the ports. The chamber includes a vent wall that is angled to provide additional vent area so as to improve cooling of the connector. An aperture array in a rear wall of the cage can be used to further improve the cooling capabilities of the connector.

First claim

1 . A connector, comprising:
a housing that includes a mounting face and a mating face and a first card slot and a second card slot on the mating face, the first and second card slots being vertically spaced apart; a plurality of terminals supported by the housing, the terminals including tails arranged at the mounting face and contacts positioned in the card slots; a cage positioned around the housing, the cage having a front face that defines a first plane, the cage defining a first port and a second port that are aligned, respectively, with the first and second card slots, the cage including a chamber between the first and second ports; and a vent wall positioned in the chamber adjacent the front face, the vent wall having a plurality of openings sized so as to block electromagnetic interference (EMI), the vent wall arranged at a first angle from the first plane that is at least 15 degrees; wherein the plurality of openings collectively define a vent area.

2 . The connector of claim 1 , wherein the chamber has a first area corresponding to a height and a width of the chamber and the vent area is at least 60% of the first area.

3 . The connector of claim 2 , wherein the vent area is at least 75% of the first area.

4 . The connector of claim 2 , wherein the vent area is at least 100% of the first area.

5 . The connector of claim 1 , wherein the first angle is at least 30 degrees from the first plane.

6 . The connector of claim 5 , wherein the first angle is about 45 degrees.

7 . The connector of claim 1 , wherein the first angle is between 15 and 45 degrees from the first plane.

8 . The connector of claim 1 , wherein the connector further comprises an insert positioned between the first and second ports, the insert defining the chamber.

9 . The connector of claim 8 , wherein the insert includes the vent wall integrally formed in the insert.

10 . The connector of claim 9 , wherein the insert includes a top wall and a bottom wall and is configured to have an end of the vent wall press against one of the top and bottom walls.

11 . A connector, comprising:
a housing that includes a mounting face and a mating face and a first card slot and a second card slot on the mating face, the first and second card slots being vertically spaced apart; a plurality of terminals supported by the housing, the terminals including tails arranged at the mounting face and contacts positioned in the card slots; a cage positioned around the housing, the cage having a front face that defines a first plane, the cage defining a first port and a second port that are aligned, respectively, with the first and second card slots, the ports having a first width; and an insert positioned between the ports, the insert including a first wall that forms a bottom of the first port and a second wall that forms a top of the second port, the first and second wall spaced apart by a first height such that the first height and the first width define a chamber, the insert including a vent wall positioned in the chamber adjacent the front face, the vent wall having a plurality of openings sized so as to block electromagnetic interference (EMI) and having a surface area that is greater than the first width times the first height; wherein the plurality of openings collectively define a vent area.

12 . The connector of claim 11 , wherein the first height and the first width define a chamber area and the vent area is at least 75% of the chamber area.

13 . The connector of claim 11 , wherein the vent wall is at a first angle that is at least 30 degrees from the first plane.

14 . The connector for claim 11 , wherein the cage includes a rear wall and an aperture array positioned in the rear wall, the aperture array in communication with vent wall so that air may flow from one to the other.
