Description

Technical Field

[0001] The utility model relates to the technical field of electronic component quality inspection, in particular to a voltage detection device. Background Art

[0002] At present, after the production and processing of electronic components, it is necessary to carry out quality inspection on the produced electronic components, including voltage detection of electronic components. A voltage detection device is needed to detect and count the voltage caused by the normal operation of electronic components, and it has the functions of monitoring, analysis, memory, query, parameter setting, etc.

[0003] The utility model with the prior art publication number CN209878875U involves a voltage detection device. When detecting the device to be tested, the detection interface is first connected with the output interface of the device to be tested. Since the connection process is interface to interface, short circuit sparking or electric shock to personnel will not occur. The detection interface transmits the voltage output by the output interface of the device to be tested to the voltage processing circuit. The voltage processing circuit processes the voltage and transmits it to the display unit, which is displayed by the display unit, making the detection more intuitive. Therefore, it effectively avoids the occurrence of touch short circuit and the like during the detection process, and the detection is more convenient, fast and safe.

[0004] However, the above-mentioned device still has the following problems when in use: when the existing voltage detection device is used, most of them adopt a single voltage stabilizing module structure design. When the voltage detection work of the actual electronic component quality inspection is carried out for a long time, the deviation of the voltage detection is large. At the same time, the voltage stabilizing part of the existing voltage detection device is very easy to accumulate heat. After a long period of voltage detection work, the voltage stabilizing part is very easy to overheat and burn. Utility Model Content
