According to the circular connector and the connector assembly of the various embodiments of the present disclosure, the circular connector of the connector assembly is directly electrically connected with the nut by integrally forming the elastic contact structure adapted to elastically contact with the inner wall of the nut on the shielding sleeve, so that the number of connecting members (e.g., springs) is reduced, the manufacturing cost is reduced, and the connection between the shielding sleeve and the nut is more reliable, and the assembly is convenient and simple to operate.
