摘要： A method for testing a multicore cable that includes a single common shield covering plural insulated wires. The testing method includes inputting a test signal, by capacitive coupling, to an end portion of the insulated wire under test among end portions of the insulated wires exposed at one end of the multicore cable, and measuring voltages of output signals output by capacitive coupling respectively from end portions of the insulated wires exposed at the other end of the multicore cable, and identifying the other end portion of the insulated wire under test based on the measured voltages. The voltages of output signals are measured in a state that an output variation reduction capacitive element is connected in series with a coupling capacitance generated by the capacitive coupling.

摘要： A cable signal detector is configured to detect the presence or absence of information communication in a communication cable including a plurality of signal line pairs for differential signaling. The cable signal detector includes a plurality of detecting portions each of which is configured to partially branch and draw a transmission signal from a different signal line pair, rectify the branched and drawn signal into a direct current, and output that direct current, and a displaying portion configured to display the presence or absence of information communication, based on outputs of the plurality of detecting portions. The outputs of the plurality of detecting portions are connected in series, and the displaying portion is configured to display the presence or absence of information communication, based on an overall output voltage of the plurality of detecting portions connected in series.

摘要： An assembling method for a multi-core cable having a plurality of electrical insulated wires is designed to connect one-end-portions of the electrical insulated wires to electrode patterns, respectively, of one circuit board, correspondingly connect other-end-portions of the electrical insulated wires to electrode patterns, respectively, of the other circuit board, compute intersection coefficients on one end side and the other of the cable, and iterate interchanging connecting destinations for the one-end-portions of the electrical insulated wires, correspondingly interchanging connecting destinations for the other-end-portions of the electrical insulated wires, and computing the intersection coefficients on the one end side and the other of the cable. The connecting destinations for the electrical insulated wires to the electrode patterns are determined in such a manner that a maximum intersection coefficient denoting either larger one of the respective intersection coefficients of the one end side and the other of the cable is made small.
