Abstract

A connector assembly can be provided. A receptacle includes terminals that can be positioned in a card slot on a 0.60 mm pitch (or greater). A biasing element can be provided in the card slot to engage a mating paddle card. The receptacle can be configured to allow air to flow from a front face to a rear face, the air passing through a middle wall. A plug assembly can be provided that includes a conductive body and is configured to generate some amount of heat. The body can include a surface that has cooling grooves. The cooling grooves allow air flow over the plug assembly so that the plug assembly can be cooled directly.

First claim

1 . A connector system, comprising:
a cage that includes a front face and a rear face and first port and a second port and a central duct between the two ports; and a housing positioned in the cage, the housing having a first card slot aligned with the first port and a second card slot aligned with the second port; wherein the cage and housing are configured to allow air to flow from a the front face to the rear wall, the air passing through the center duct.

2 . The connector of claim 1 , wherein the first card slot includes a plurality of terminals arranged on a pitch that is between about 0.6 mm and 0.65 mm, the card slot including a biasing member on one side.

3 . The connector of claim 1 , wherein the housing supports light pipes.

4 . The connector of claim 1 , further comprising a middle wall, the middle wall having apertures configured to allow the air to flow past the middle wall.

5 . A plug connector, comprising:
a housing have a top surface and a bottom surface, the housing being formed of a thermally conductive material; and a paddle card positioned in the housing, the paddle card extending toward a front end of the plug connector; wherein one of the top surface and the bottom surface has grooves extending along a length of the plug connector.

6 . The plug connector of claim 5 , wherein the paddle card has contact pads on a 0.6 mm pitch and the contact pads are aligned with a side of the paddle card.

7 . An connector assembly, comprising:
a receptacle with a cage that defines a port and a housing positioned in the cage, the cage having a rear wall and the housing having a card slot aligned with the port, the card slot having a plurality of terminals with contacts positioned in the card slot, the contacts forming a row and being on a pitch that is between 0.59 mm and 0.66 mm, the card slot having a biasing element positioned on a first side of the card slot; a plug assembly positioned in the port, the plug assembly including a body and a paddle card with pads that engage the contacts, the paddle card having an edge that is pressed against a second side of the card slot, the first side being opposite the second side.

8 . The assembly of claim 7 , wherein the receptacle is a stacked connector and the port is a first port, the connector further including a second port arranged vertically over the first port, the housing further supporting a second card slot aligned with the second port, the second slot having a biasing element on a first side of the card slot.

9 . The assembly of claim 8 , wherein the receptacle assembly includes a front face and a rear face and a middle wall positioned between the front face and the rear face, the middle wall having middle apertures that allow air to flow through the middle wall, the connector further comprising a central duct that is configured to allow air to flow from the front face to the middle wall.

10 . The assembly of claim 9 , wherein the receptacle includes an insert positioned in the central duct at the front face and the insert includes apertures to allow air to flow through the insert and into the central duct.

11 . The assembly of claim 10 , wherein the housing is spaced apart from the cage so that air can flow from the middle wall to the rear wall in a space between the housing and the cage.

12 . The assembly of claim 11 , wherein the middle wall includes apertures aligned with the first and second ports and configured to allow air flowing through the ports to pass through the apertures.

13 . The assembly of claim 7 , wherein the pads are aligned with the edge of the paddle card.

14 . The assembly of claim 7 , wherein the plug assembly includes a first surface on the body and the first surface includes a plurality of cooling grooves configured to allow air to flow through the port while the plug assembly is positioned in the port.

15 . The plug connector of claim 5 , wherein the housing includes a portion that is intended to be inserted into a port and the cooling grooves extend along the entire portion.
