Abstract

The invention is suitable for the technical field of circuit testing, and provides a flat cable detection device. According to the flat cable detection device, at least one plug wire seat group and aplurality of diodes are arranged on a test circuit board, and each plug wire seat group comprises a first plug wire seat and a second plug wire seat which are used for being connected with the two ends of a flat cable to be detected respectively; a plurality of first pins in the first plug wire seat are used for receiving test signals sent by a test machine, and a plurality of second pins in the second plug wire seat are respectively and correspondingly connected with positive electrodes of the plurality of diodes; the negative electrodes of the plurality of diodes are connected with the powerground. The test machine transmits test signals to N diodes in the plurality of diodes through N wires of the flat cable to be tested in sequence, the currents or voltages at the two ends of the N diodes are measured to judge whether the N wires are open-circuited or short-circuited or not, whether the N wires are open-circuited or short-circuited or not can be sequentially detected, and comparedwith manual detection of the to-be-detected flat cable, the flat cable detection device is high in flat cable detection efficiency.

Description

technical field [0001] The application belongs to the technical field of circuit testing, and in particular relates to a cable detection device. Background technique [0002] In the circuit field, the application of the cable is very extensive, and the cable is the main connection tool between multiple components. When testing existing chips, it is necessary to use a cable to connect the testing machine and the test probe, and then test the chip. However, the cable is easily damaged after repeated use, and the damaged cable will lead to unprepared chip test results. However, the existing methods for detecting whether the cable is good or bad are to check one by one manually using a multimeter, and the detection efficiency is low. Contents of the invention [0003] The embodiment of the present application provides a cable arrangement detection device, which can solve the problem of low efficiency of the existing cable arrangement detection. [0004] An embodiment of the ...
