Description

Cable detection device

Technical Field

The utility model relates to the technical field of cable detection, in particular to a cable detection device.

Background Art

The principle of the existing wire harness detection device is shown in Figure 1. It is realized by the cooperation of resistors and buzzer driving circuits. When testing a resistance less than a certain value, the potential of the inverting input terminal of the comparator is pulled low, and the potential of the non-inverting input terminal is greater than the potential of the inverting input terminal. The comparator outputs a high level and drives the buzzer to sound; when the measured value is greater than this value, the potential of the inverting input terminal is greater than the potential of the non-inverting input terminal, the comparator outputs a low level, and the buzzer does not sound. Good products and defective products are judged by whether the buzzer sounds.

However, the above-mentioned harness detection device has the following disadvantages: during the detection process, one end of the device is connected to the hole of a core of the cable to be tested, and the other end of the device is connected to the corresponding position. The buzzer sounds to determine whether the line is good. If a single person wants to complete the detection, it is necessary to hold the two ends of the cable to be tested with one hand and insert the two ends of the detection device into the holes with the other hand, which is difficult to operate. Therefore, it usually takes two people to complete the detection, but the cost is increased. In addition, the number of cores of the power line, encoder line, and communication line is large, and it is easy to miss, make mistakes, and be inefficient if they are checked one by one.
