Abstract: This application discloses a female connector, a male connector, a connector assembly, a cable assembly, a device, and a communication system. The female connector includes two terminal groups, contact sections of a plurality of terminals of the two terminal groups are symmetrically disposed, and terminal signal sequences are opposite. Each terminal group includes a plurality of power terminal pairs and a plurality of high-speed terminal pairs. The power terminal pair includes a power terminal and a power return ground terminal. The high-speed terminal pair includes two adjacent high-speed signal terminals. Cross-sectional areas of contact sections of the power terminal and the power return ground terminal are greater than a cross-sectional area of a contact section of the high-speed signal terminal, to meet high power and high transmission rate requirements.
