Abstract
The present invention is available in hub technique field and provides a hub, which comprises a circuit board, a plug coupled to the circuit board, an upper cover and a bottom cover. The upper cover and the bottom cover cooperatively package the circuit board therein. The circuit board comprises at least one board socket facing toward the upper cover. The upper cover defines a first insertion opening disposed to be aligned with the board socket. The hub further comprises a rotating cover. The rotating cover is interposed between the upper cover and the circuit board and is coupled to and rotatable about the upper cover. The rotating cover defines a second insertion opening disposed to be aligned with the board socket. The rotating cover covers the board socket when the rotating cover is positioned at a first position. The first and the second insertion openings are in communication with each other to expose the board socket when the rotating cover is positioned at a second position. The present invention uses the rotating cover to cover the board socket when the hub is not in use, thereby preventing the hub from external corrosion. When use, the first and the second insertion openi…
