Method for inspecting multi-core cable, method for manufacturing multi-core cable assembly, and inspection device for multi-core cable

摘要

To suppress a variation of output voltage due to the variation in a coupling capacity, and to provide a method for inspection of a multi-core cable to improve the detection accuracy.SOLUTION: In the multi-core cable 2 having a bulk shield 21 covering a plurality of insulated wires 3 together, an inspection signal is inputted by capacitance coupling at an end of the insulated wire 3 to be inspected exposed at one end of the multi-core cable 2, the voltage of the output signal outputted by capacitance coupling from each end of the insulated wire 3 exposed at the other end of the multi-core cable 2 is measured, identifies the end of the other side of the insulated wire 3 to be inspected based on the measured voltage, measures the voltage of the output signal in series with respect to the coupling capacitance caused by the capacitance coupling by connecting an output variation reduction capacitance element 9.SELECTED DRAWING: Figure 1
