Abstract: The invention relates to communications technologies and discloses a rotation axis, a digital device and a Universal Serial Bus (USB) device. The rotation axis includes a sleeve, an elastic body, an indented washer, and a movable support. The sleeve includes a lip and a cylinder. The elastic body, the indented washer, and the movable support are configured sequentially around the cylinder with the lip adjacent to the elastic body along the axial direction of the cylinder beginning with the lip. A number of concave indents are configured on one end-surface of the indented washer and distributed on a circle. The end-surface of the indented washer where the concave indents are configured contacts one end-surface of the movable support. A number of protrusions are configured on the end-surface of the movable support to mate the concave indents. In the invention, a rotation axis is constituted by a few parts including a sleeve, an elastic body, an indented washer, and a movable part. Therefore, the rotation axis is characterized by simple structure, small size, low cost, and good reliability.

Abstract: In the field of data cards with a rotatable external port, a data card with a rotatable connector and a rotatable connector for a data card are provided. The data card with a rotatable connector includes a data card body and a rotatable connector, where the rotatable connector includes an external port for connecting with an external device, and the rotatable connector is rotatably connected with the data card body. The data card further includes an antenna set in the rotatable connector. The rotatable connector for a data card includes a rotatable connector body and an external port for connecting with an external device, and includes an antenna therein. Through setting the antenna in the rotatable connector, no matter what angle the data card is rotated, the antenna is always maintained in the same state, so that the antenna can be modulated in advance, so as to eliminate the interference on the performance of the antenna caused by the external device, and ensures stable performance of the antenna.
