An electrical connector for conducting high frequency signals includes a number of input and output terminals that are interconnected by a pair of metallic lead frames that are mounted on a dielectric spring block. The lead frames are identical to each other and comprise several flat elongated conductors, each conductor terminating in a spring contact at one end and an insulation-displacing connector at the other. The lead frames are mounted on top of each other and their conductors are all generally parallel and close to each other. Only three of the conductors of each lead frame are arranged to overlap each other; and this occurs in a designated crossover region without electrical contact being made because of a reentrant bend in the conductors in the crossover region. As a result, crosstalk between specific conductors can be reduced by judiciously choosing the location of the crossover and the particular crossover pattern.
