Abstract
Abstract A connector is provided of the type that has rows of contacts, which minimizes crosstalk between adjacent contacts. An interceptor plate (60, FIG. 2) which is grounded or at another controlled potential, extends along each row of contacts (34), the plate lying close to the row to provide better capacitive coupling between each contact and the plate than between contacts of the same or different rows. The space between each contact leg and an adjacent interceptor plate, contains a dielectric whose dielectric constant varies by no more than four per cent between 1 kHz and 100 MHz. The capacitance between each contact and an adjacent interception plate is at least three times the capacitance between adjacent contacts of a row.
