Abstract

PURPOSE: To shorten the delay time in signal transmission and preclude deterioration of the waveform of the transmitted signal by relieving reflex noises and cross-talk noises on a signal transmission line.
CONSTITUTION: Signal pins 31 and ones 41 of connector member 30/40 are surrounded each with a mass of insulator part 32/42 made of a material having low dielectric constant or a material having a small dielectric tangent without provision of any protruding part into the air. Those portions of signal pins 31/41 which are situated in the respective insulator mass 32/42, are isolated magnetically by a metal shield plate 34/44 while they are grouped into a combination of signal pins to perform differential signal transmission.
