Abstract
To provide a connector enabling high quality signal transmission while maintaining compatibility with the current HDMI connector, in a new HDMI interface using pins assigned to a shield, as a data pair. Each of signal electrode pins is arrayed near a shell (grounding conductor) so as to couple with the shell, and differential signals are transmitted with single end. A ground plane is disposed between multiple signal electrode pins of a first stage and the plurality of signal electrode pins of a second stage within a dielectric. Also, connection conductors electrically connecting the ground plane and the grounding conductor are disposed between each of the signal electrode pins of each of the stages within the dielectric. With a pair of signal electrode pins transmitting differential signals, crosstalk from other signal electrode pins can be reduced, and high quality signal transmission is enabled.
