Contact modules for receptacle assemblies

A contact module for a receptacle assembly comprising:

• a conductive holder having a mating end and a mounting end, the mounting end being configured to be coupled to a circuit board in a mounting direction;
• a frame assembly received in the conductive holder and electrically shielded by the conductive holder, the frame assembly having a plurality of receptacle signal contacts, the receptacle signal contacts having mounting portions extending from the conductive holder, the receptacle signal contacts being arranged in differential pairs carrying differential signals;
• and
• a ground shield received in the conductive holder between the frame assembly and the conductive holder, the ground shield being electrically connected to the conductive holder, the ground shield having a mounting end with ground pins extending from a mounting edge at the mounting end of the ground shield, the ground pins extending along the mounting portions of the receptacle signal contacts, the ground pins being configured to be coupled to the circuit board when the conductive holder is mounted to the circuit board in the mounting direction, wherein forces are imparted on the ground pins during coupling with the circuit board, the mounting end having a plurality of bearing surfaces proximate to the ground pins, the bearing surfaces engaging at least one of the conductive holder and the frame assembly to transfer the forces between the ground shield and at least one of the conductive holder and the frame assembly.
