  • Patent number: 7033224
    Abstract: An electrical connector assembly (1) includes a first connector (2) and a second connector (3). The first connector includes a first housing (21) and first electrical contacts (22). The second connector includes a second housing (31) and second electrical contacts (32). The first contacts include signal contacts (22A), ground contacts (22B), and shield-joint contacts (22C). The signal contacts are arranged in pairs, with each pair transmitting one set of differential signals. The signal contacts within each pair are separated by an empty passage (214). Adjacent pairs of signal contacts are separated by one ground contact or by one shield-joint contact. The second contacts are configured to correspond to the first contacts, so that the first and second contacts can electrically mate with each other to electrically interconnect the first and second connectors.
