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

I claim:

1. A 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, 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, the card slot extending between the first and second sides such that a top of the card slot and a bottom of the card slot are closer together than the first side is to the second side.

2. The assembly of claim 1 , 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.

3. The assembly of claim 1 , wherein the contacts are on a pitch that is between 0.59 mm and 0.66 mm.

4. The assembly of claim 1 , wherein the pads are aligned with the edge of the paddle card.

5. The assembly of claim 1 , 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 and wherein the first surface includes a portion that is intended to be inserted into the port and the cooling grooves extend along the entire portion.

6. 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 first card slot aligned with the first port and a second card slot aligned with the second port, the first and second card slots each form openings that extend between opposite ends a greater distance than between top and bottom and are each configured to receive a paddle card,
wherein the first card slot includes a first biasing member on a first end of the first card slot, the first biasing member configured to press an edge of a paddle card, when inserted into the first card slot, against an end of the card slot opposite the first end, and
wherein the second card slot includes a second biasing member on a second end of the second card slot, the second biasing member configured to press an edge of a paddle card, when inserted into the second card slot, against an end of the card slot opposite the second end.

7. The connector system of claim 6 , 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.

8. The connector system of claim 6 , further comprising a housing positioned in the cage, wherein the housing supports light pipes.

9. A receptacle, comprising:
a cage defining a port and having a rear wall;
a card slot positioned in the cage and being aligned with the port, the card slot forming an opening that extends between opposite ends of the card slot a greater distance than between a top and bottom of the card slot, the card slot being configured to receive a paddle card; and
a plurality of terminals with contacts positioned in the card slot, the contacts forming a row,
wherein the card slot includes a biasing member on a first end of the card slot, the biasing member configured to press an edge of a paddle card, when inserted into the card slot, against an end of the card slot opposite the first end.

10. The receptacle of claim 9 , wherein the receptacle comprises a stacked connector and the port is a first port, the receptacle further including a second port arranged vertically over the first port and a second card slot aligned with the second port, the second card slot having a biasing element.
