IMPEDANCE MATCHED BACKPLANE CONNECTOR

摘要

An electrical connector is shown which is mountable to a printed circuit board (200) which includes a plurality of insulating housings (4). A vertical row of terminals is formed as a subassembly (60) where the terminals (72 to 75) are integrally molded within an insert (82) of dielectric material. The lengths of the sections of the terminals (72 to 75) which are within the molded insert (82) vary to alter the impedance of the terminals (72 to 75), thereby matching the overall impedance of the terminals (72 to 75). Cross-talk shield members are insertable into the rear of each connector housing (4) to shield adjacent vertical rows of terminals from cross-talk. Upper (100) and lower shield members are insertable over the assembly to shield the assembly from EMI/RFI.
