US Patent 11784440 Keyed input/output connector

A cage includes a cage housing forming an inner area with internal walls that define an upper port and a lower port. Each of the ports include a cap that forms a keyway. The cap in an upper bay can extend from the upper bay in a direction that is opposite a direction the cap in the lower port extends. The cage may include a plurality of spring fingers therein which engage with a conductive bezel. The cage provides EMI shielding for the plug connector.
