Description

technical field [0001] The invention relates to an electrolytic capacitor polarity detection circuit, relates to the technical field of circuit detection, in particular to an electrolytic capacitor polarity detection circuit and a detection device. Background technique [0002] With the rapid development of modern society, electrolytic capacitors are divided into positive polarity and negative polarity. When the electrolytic capacitor is integrated on the circuit board, the polarity may be reversed. The reversed polarity of the electrolytic capacitor may lead to a decrease in the reliability of the circuit board and functional failure. . At present, when detecting whether the electrolytic capacitor is inserted backward, it mainly relies on manual detection or AO equipment for comparative analysis. In addition, it uses the difference in leakage between the positive and negative electrodes and the shell for detection. There are following problems at prior art: [0003] 1. In...

Another purpose is to have a control heat insulator and a middle heat insulation board layer, which is convenient to solve the problem of the main body after the detection time is too long when the existing circuit detection device is in use. It will generate a lot of heat, so that the surface of the device will become very hot, and the skin will be burned when touched. Through the above structure, the device can isolate the heat during use, so that the surface of the device will not become too hot , to avoid damage to the skin when touched, and to prevent the spontaneous combustion of the circuit due to too high heat
