An electrical connector includes a housing, contacts, ground shields, and a ground frame. The housing extends between a front end and an opposite rear end. The front end is configured to be mated with a mating connector. The contacts and ground shields are held by the housing. The ground shields at least partially surround the contacts to provide electrical shielding for the contacts. The ground frame has a first side coupled to the rear end of the housing and a second side facing the circuit board. The contacts have terminating ends and the ground shields have mounting ends. The terminating ends and the mounting ends extend from the rear end of the housing through the ground frame for termination to the circuit board. The ground frame engages the ground shields to electrically join the ground shields.

The electrical connector of claim 1, wherein the housing is an electrical insulator and the ground frame is an electrical conductor, the connector further comprising a pin organizer coupled to the second side of the ground frame, the pin organizer being an electrical insulator to electrically insulate the ground frame from the circuit board. 4. The electrical connector of claim 1, wherein the ground shields include C-shields and orphan shields, each C-shield extending along a corresponding pair of the receptacle contacts on three sides, each orphan shield extending along a corresponding pair of the receptacle contacts on one side. 5. The electrical connector of claim 1, wherein the receptacle contacts are organized in pairs carrying differential signals, each pair of the receptacle contacts is held in a non-conductive overmold body, the overmold body engaging a surrounding ground shield and electrically insulating the respective pair of the receptacle contacts from the surrounding ground shield. 6. The electrical connector of claim 5, wherein the overmold body includes ribs that force the surrounding ground shield outward against the ground frame. 7. The electrical connector of claim 1, wherein the ground shields are arranged in columns and rows, the ground frame engaging the ground shields disposed in different columns and in different rows to electrically join the ground shields of the different columns and the different rows. 8. The electrical connector of claim 1, wherein the ground frame is a stamped and formed plate, the openings of the ground frame including signal openings configured to receive the terminating ends of the receptacle contacts and ground openings configured to receive the ground contacts and rear portions of the bases of the ground shields. 9. The electrical connector of claim 8, wherein the base of each of the ground shields includes an exterior surface and an opposite, interior surface that faces the receptacle contacts that the respective ground shield at least partially surrounds, the ground openings of the ground frame having projections that engage the interior surface and the exterior surface of the rear portion of the base of the corresponding ground shields extending therethrough. 10. The electrical connector of claim 1, wherein the ground frame is at least one of a metal-plated plastic ground housing or a molded metal ground housing. 11. The electrical connector of claim 1, wherein the housing defines plural cavities that extend between the front end and the rear end, each cavity having a pair of the receptacle contacts and a ground shield loaded therein, the openings of the ground frame aligning with the cavities of the housing. 12. The electrical connector of claim 11, wherein the openings of the ground frame are smaller than the cavities of the housing, the ground frame configured to be coupled to the housing after the pairs of the receptacle contacts and the ground shields are loaded into the cavities of the housing, edges of the openings of the ground frame providing a wall that blocks the pairs of the receptacle contacts and the ground shields from exiting the cavities through the rear end of the housing. 13. The electrical connector of claim 1, wherein the housing defines plural cavities that extend between the front end and the rear end, each cavity having a pair of the receptacle contacts and a ground shield loaded therein, the housing including deflectable retention latches within the cavities, each retention latch having a first tab configured to retain the ground shield in the respective cavity and a second tab configured to retain the pair of the receptacle contacts in the cavity. 14.
