The technology of this application relates to a shielding piece, a female connector, and a connector assembly. The shielding piece includes a main body and a contact portion, and the contact portion is connected to the main body by using at least two elastic arms or a connecting portion. The connecting portion surrounds the contact portion, and forms, jointly with the contact portion, a convexity protruding from the main body. The at least two elastic arms are connected to the main body at a periphery of the contact portion along different directions, and a gap is formed between the main body and the at least two elastic arms. The contact portion is configured to abut against a ground terminal of a male connector.
