A high-speed differential terminal path compensation structure for a USB Type-C connector

Abstract

This invention discloses a high-speed differential terminal path compensation structure for a USB Type-C connector, including an insulating body and multiple conductive terminals disposed within the insulating body. Among the conductive terminals are multiple high-speed differential terminals for high-speed differential signal transmission. At least one high-speed differential terminal has a path compensation structure along the transmission path from the contact mating section to the solder joint section. The path compensation structure includes at least two path compensation bends formed sequentially along the terminal extension direction, so that the high-speed differential terminal forms a non-linear transmission path that is extended relative to the linear transmission path, thereby increasing the effective electrical length of the corresponding high-speed differential terminal and compensating for the transmission path length difference between different high-speed differential signal channels. This invention can improve the path consistency and signal transmission performance of high-speed differential terminals without significantly changing the overall mounting boundary of the connector, and has good practical value.
