  • Patent number: 11101611
    Abstract: An I/O connector assembly configured for making a cabled connection to an interior portion of a printed circuit board for at least some signals passing through the I/O connector. The I/O connector assembly may be assembled by mounting a cage to a printed circuit board. A receptacle connector, including cables extending from a rear of the connector, may be inserted through an opening in the top or rear of the cage. The receptacle connector may be positioned in the cage by at least one retention member on the cage. A plug, mating to the receptacle connector, also may be positioned by a retention member on the cage. Positioning both the plug and receptacle relative to the cage reduces the tolerance stackup of the assembly and enables the connectors to be designed with shorter wipe length, which enables higher frequency operation.
