Abstract: A portable electronic device including a main body having one end concavely provided with a receiving groove, a pivot pin provided in the receiving groove, a pivot seat pivotally connected to the pivot pin, a transmission line having one end electrically connected to a circuit board provided in the main body and the other end extending into the receiving groove, and a plug having one end embedded in the pivot seat. Since the pivot pin has a hollow configuration, the other end of the transmission line is able to pass through the pivot pin and be electrically connected to the plug, allowing the plug to be rotated and received in the receiving groove when the portable electronic device is not in use and preventing the transmission line from being pulled or curled due to rotation of the plug.

Abstract: The present invention is to provide a sheath type router, which comprises a sheath, a printed circuit board, a battery and at least one antenna. The sheath is foldable and sheathable to a mobile terminal device. The printed circuit board and battery are enclosed in the sheath and electrically coupled together, wherein the printed circuit board includes a central processing unit, a wireless module, a communication module, a subscriber identity module port, at least one input/output port and a power switch, and the central processing unit is electrically coupled to the wireless module, communication module, ports and power switch respectively. When the power switch is turned ON, the printed circuit board is able to receive electric power from the battery, and the mobile terminal device fixed onto the sheath can connect to the wireless module through the antenna as well as connecting to a corresponding network through the communication module.
