Multiconductor connector adapted to be connected to a plurality of paired cables for high-speed transmission a signal

A multiconductor connector for high-speed transmission signal for connecting a plurality of paired cables includes an insulator plate having signal contacts on its upper and lower surfaces. The signal contacts are arranged in a row on each of the upper and lower surfaces to form pairs of the two signal contacts aligned with each other above and below across the insulator plate. The insulator plate has a thickness so determined that when a pair of terminal of each of the paired cables are exposed at their one ends by removing their insulating coverings and then fitted on the insulator plate without changing the initial spacing between the pair of terminals in a manner embracing the insulator plate by the pair of terminals on the upper and lower surfaces, the pair of terminals are electrically connected to a pair of the signal contacts on the upper and lower surfaces of the insulator plate. With this arrangement, good impedance characteristics at the one ends of the paired cables can be maintained.
