An electrical connector for a circuit card assembly including a PCB includes a mating housing having a mating end movable relative to the PCB and contact modules coupled to the mating housing including signal contacts having a mating conductor, a mounting conductor and a flexible conductor. The flexible conductor is flexible to allow relative movement of the mating conductor relative to the mounting conductor. The flexible conductor has a bent portion changing shape. The contact modules have ground contacts providing electrical shielding for the signal contacts. The ground contacts include covers extending along and providing shielding along at least one side of the bent portion of the corresponding signal contact.
