Abstract: An overvoltage protection circuit and a portable electronic device having the same are introduced. The overvoltage protection circuit provides overvoltage protection when an input voltage exceeds a rated voltage tolerable by an internal circuit unit in the portable electronic device. A reference voltage and a partial voltage are generated from the input voltage through a voltage limiting unit and voltage dividing module, respectively, and conveyed to a comparing module for comparison. Comparison of the reference voltage and the partial voltage is followed by generation of a switch signal whereby a switch unit determines whether to apply the input voltage to the internal circuit unit. The voltage dividing module sets the maximum rated voltage tolerable by the internal circuit unit and enables the overvoltage protection circuit to give overvoltage protection to the portable electronic device regardless of temperature.

Abstract: A cable has a conductor keeper, multiple bare conductors, a dielectric tape, a plastic jacket and two copper cylinders. The conductor keeper has multiple grooves. Each bare conductor is mounted in a corresponding groove of the conductor keeper and has a first end and a second end. The first end and second end of the bare conductor protrude out of the conductor keeper respectively so as to form two spaces. The dielectric tape is wrapped around the conductor keeper. The plastic jacket is coated around the dielectric tape. Two copper cylinders are mounted in the spaces of the bare conductors respectively to make the bare conductors surround the copper cylinders and the bare conductors connect to each other in parallel. Therefore, the skin effect is minimized and the bare conductors are efficient in that power consumption and emission of carbon dioxide during copper-smelting are significantly reduced.
