Contact assembly for an electrical connector

A contact assembly for an electrical connector includes an array of contacts including signal contacts and ground contacts. The ground contacts are interspersed with the signal contacts to provide electrical shielding between corresponding signal contacts. Each signal contact includes a signal contact body having a first side, a second side opposite the first side, a first edge between the first and second sides, and a second edge between the first and second sides opposite the first edge. The signal contact body includes a signal mating end and a signal terminating end. Each signal contact includes a mating ball formed at the signal mating end of the signal contact body. The mating ball is generally spherical shaped. The mating ball and the signal contact body are a homogeneous structure.
