Abstract

An electrical connector assembly has a terminal housing, and a number of electrically conductive connector assembly terminals supported by the housing. The connector assembly terminals have mid-sections that protrude from the housing for contacting terminals of a mating connector, and outside connection ends for making electrical connections with outside circuits. Free ends of the connector assembly terminals next to the terminal mid-sections and opposite the outside connection ends, are positioned inside the terminal housing. An electrical circuit component is mounted inside the terminal housing. The circuit component is connected to the free ends of the assembly terminals, so that the mating connector becomes electrically connected to the circuit component through paths between the mid-sections and the free ends of the assembly terminals, in proximity to the circuit component. The electrical circuit component may be constructed and arranged to compensate for cross talk induced when the mating connector contacts the mid-sections of the assembly terminals.

Claims

5. A connector assembly according to claim 1, wherein said electrical circuit component is constructed and arranged to produce cross talk of substantially equal magnitude and opposite phase to cross talk produced when the mating connector contacts the mid-sections of the connector assembly terminals.

6. The connector assembly of claim 1, wherein the electrical circuit component is a first stage of a multi-stage cross talk compensation arrangement.

7. The connector assembly of claim 6, wherein said multi-stage compensation arrangement comprises an outside circuit board to which the outside connection ends of said connector assembly terminals are connected.
