对多芯电缆来讲,要确定其中断线及断点位置是比较困难的。比如压塑接头的通信电缆,有时一个接头处的断线要打开许多接头后才能查出,极不方便。本人参考其他电路,使用一片4060芯片及少量外围元件设计一简单的多芯电缆断线检查器,可帮助从电缆一端检查是否存在断线并初步判定断点位置。
For multi-core cable, it is more difficult to determine the location of its break and breakpoint. Such as compression molded connector communication cable, and sometimes a connector at the disconnection to open many joints can be detected, very inconvenient. I refer to other circuits, the use of a 4060 chip and a small amount of external components to design a simple multi-core cable break checker can help check from one end of the cable is disconnected and initially determine the breakpoint location.
