WIPO Patent Application WO/2012/077612

A1

[Objective] To provide, in a new HDMI interface wherein a pin assigned to a shield is used as a data pair, a connector that is able to conduct high-quality signal transmission, while maintaining compatibility with HDMI connectors currently in use. [Solution] Signal electrode pins (252, 152) are arranged to be close to shells (ground conductors) (253, 153), respectively, so as to couple therewith, and signals are transmitted in single-ended state. Ground planes (254, 154) are arranged between a plurality of signal electrode pins of a first tier and a plurality of signal electrode pins of a second tier, both of which exist within dielectrics (251, 151). Connecting conductors (255, 155), which electrically connect the ground planes and the shells, are arranged between each of the signal electrode pins of each of the tiers within the dielectrics (251, 151). In a pair of signal electrode pins for transmitting a differential signal, crosstalk from other signal electrode pins can be reduced, enabling high-quality signal transmission.
