Abstract
An improved electric circuit structure for short circuit protection is applicable to examining a device under test, comprising a circuit breaking element, a thermistor, a filtering and rectifying module and a capacitor. A first end of the circuit breaking element is electrically connected to a power source. A first end of the thermistor is electrically connected to a ground. The filtering and rectifying module is connected between the second end of the circuit breaking element and the second end of the thermistor. The capacitor is connected to the filtering and rectifying module and in parallel with the device under test. The circuit breaking element disclosed in the present invention is a multi-protector fuse and forms an open circuit when the device under test forms a short circuit. Meanwhile, the multi-protector fuse is able to withstand voltage between its first and second end without generating any physical damage.
