CONNECTOR UNIT, CONNECTOR, CIRCUIT BOARD, ELECTRONIC APPARATUS, AND ELECTRONIC SYSTEM

Embodiments of this application provide a connector body, a connector, a circuit board, an electronic device, and an electronic system, and relate to the field of electronic system accessory technologies, to improve a problem of poor SI caused when different electronic components are electrically connected by using a connector. The connector body includes a first contact part and a second contact part. The first contact part includes a first contact terminal and a first pin electrically connected to the first contact terminal. The second contact part includes a second contact terminal and a second pin electrically connected to the second contact terminal. The first contact terminal and the first pin electrically connected to the first contact terminal are integrally formed. The second contact terminal and the second pin electrically connected to the second contact terminal are integrally formed. An area of a welding surface of the first pin is less than an area of a welding surface of the second pin.
