A grounding connector includes a shell having a mating end and a mounting end. The shell defines a cavity open at the mating end configured to receive a mating component. The shell has a base at the mounting end having a plurality of contact channels open to the cavity. Grounding contacts are received in corresponding contact channels. The grounding contacts have mating ends and compliant portions opposite the mating ends. The mating ends are positioned in the cavity for mating with the mating component. The compliant portions are received in the contact channels to mechanically and electrically connect each of the grounding contacts to the shell and to each other through the shell.
