A USB connector cable includes a main cable having four separately formed wires, namely, a voltage wire, a first data transmission wire, a second data transmission wire and a ground wire, and a power cable having a voltage wire and a ground wire which are integrally and respectively formed with the voltage wire and the ground wire of the main cable.An electronic device is suitable to connect with a peripheral device and includes a circuit board, an interface and a load switch. The interface outputs a first current and at least one data signal to the peripheral device and the interface complying with a computer related standard defining a first current threshold. The interface located on said circuit board. The load switch connects to the interface and runs a second current to said interface. The load switch converts into a disconnected state while a value of the second current is excess than a second current threshold. The second current threshold is higher than the first current threshold, and the interface and the load switch are conductive under the second current threshold."/>
