Abstract
The invention relates to a cable breakage detector, which comprises a 6V direct-current power source, a 20KHz oscillating circuit, a detecting probe and an audible and visual indicating circuit. An integrated circuit IC1 in the type of CD4060 is selected. Whether cables, illuminating lines, telephone lines or network cables which are laid in walls are broken or not are quickly checked troublesomely, particularly, a universal meter cannot be simply used for testing remotely, whether insides of a motor and an induction coil are in short circuit or not needs to be determined, and normal operation can be affected once cables are not pulled out to be replaced or the motor is not replaced in time under the condition of suspected cable breakage, while an DX-A type cable breakage fault testing and positioning instrument is expensive in price and cannot be easily popularized in the fields of normal cable detection and maintenance, electrical engineering and the like. The cable breakage detector can solve the problem, and is a practical tool which is cheap in price, easy to use, reliable in detection result and easy to be popularized. A circuit of the detector only consists of normal electronic elements.
