Ground inlays for contact modules of receptacle assemblies

A receptacle assembly comprising:

• a receptacle housing;
• and
• a plurality of contact modules arranged in the housing in a stacked configuration, each contact module comprising:
• a tray having a cavity defined by inner surfaces of the tray;
• a frame assembly received in the cavity of the tray, the frame assembly having a dielectric body holding a plurality of receptacle signal contacts arranged in differential pairs carrying differential signals;
• and
• ground inlays received in the cavity between corresponding inner surfaces and the dielectric body of the frame assembly, the ground inlays having a main body including ground slats and ground flanges extending from the ground slats, wherein the ground flanges extend into the dielectric body and are positioned between differential pairs of the receptacle signal contacts.

A receptacle assembly comprising:

• a receptacle housing having a mating end;
• and
• a contact module received in the housing, the contact module comprising:
• a tray having a cavity defined by inner surfaces of the tray, the tray having a mating end and a mounting end;
• ground inlays received in the cavity along corresponding inner surfaces, the ground inlays having grounding beams extending exterior of the cavity beyond the mating end of the tray, the grounding beams being configured to engage a grounded component, the ground inlays having grounding posts exterior of the cavity beyond the mounting end of the tray, the grounding posts being configured to engage a grounded component, the ground inlays having ground slats extending between the grounding beams and the grounding posts, the ground inlays having ground flanges extending from the ground slats;
• and
• a frame assembly received in the cavity of the tray between the ground inlays, the frame assembly being electrically shielded by the ground inlays, the frame assembly having a plurality of receptacle signal contacts, the receptacle signal contacts having mating portions extending exterior of the cavity from the mating end of the tray, the receptacle signal contacts being arranged in differential pairs carrying differential signals;
• wherein the ground slats extend along opposite sides of corresponding pairs of the receptacle signal contacts and wherein the ground flanges extend between pairs of the receptacle signal contacts.
