Abstract
An electrical connector is shown which is mountable to a printed circuit board (230) which includes a plurality of insulating housings (4). The vertical row of terminals is formed as a subassembly (60) where the terminals (72-75) are integrally molded within an insert 82 of dielectric material. The lengths of the sections (72a, 73a, 74a, 75a) of the terminals (72-75) which are within the molded insert (82) vary to alter the impedance of the terminals 72-75, thereby matching the overall impedance of the terminals (72-75). Cross-talk shield members (180') are insertable into the rear of the connector housing (4) to shield adjacent vertical rows of terminals from cross-talk. Upper (100) and lower (100') shield members are insertable over the assembly to shield the assembly from EMI/RFI.
