US Patent 11177592 High performance stacked connector

A shielded I/O connector that supports high density connections. The shielded connector has a cage with channels. At least a first channel is configured to receive a transceiver such that it may be plugged into a port in a connector housing at an end of the cage. At least a second channel is configured to dissipate heat by enabling air to flow adjacent the transceiver. The rate of air flow in the second channel is increased with a channel in the connector housing that connects with the second channel. Air may exit the housing channel through openings in rear surfaces of the cage or through openings that bound the housing channel.
