Description

A rapid detection device for cable fault

technical field

The utility model relates to a rapid detection device for cable faults, which belongs to the field of electrical testing.

Background technique

The hand-held operating system that comes with the numerical control equipment is connected by the communication cable. Due to the long-term pulling, the communication line inside the communication cable is very easy to cause open circuit and virtual break failure, resulting in the poor operation of the handheld terminal and the shutdown. The cost is too high and can only be solved by continuous maintenance. At present, the on-off detection and maintenance of the cable can only be performed with a multimeter for resistance on-off detection. Since the small pins of the cable of the teach pendant are densely arranged, the pins at both ends need to be marked before testing. On the pins at both ends, the on-off status of the cable is displayed through the resistance value of the multimeter. In this method, due to the denseness of the pins, it is easy to cause overlapping or misconnection, resulting in misjudgment of faults. As for the position of the virtual break of the cable, when another person is required to bend the cable under force, due to poor contact during measurement, it is difficult to judge the position of the virtual break, resulting in frequent occurrence of cable faults that cannot be completely eradicated, and poor maintenance results. It can be solved by repurchasing new cables and replacing them, which wastes a lot of manpower, material resources and financial resources.
