High-density, impedance tuned connector

Handle having a cable connector for determining structure comprises multiple terminals' related groups; each terminal group comprises differential signal terminal is a ground reference terminal. And each group of terminal arranged on the top of connector, so that the number of reducing through the impedance, and related terminal group is inverted, so the staggered related terminal group and are terminal signal units terminal is in a line of localizations of connector, terminal units ground reference terminal and longitudinally and terminal for units signal terminal of that of the second circuit of localizations of connector. The conversion device is a density of connector.
