Description

Technical Field

[0001] The utility model relates to the technical field of circuit board assembly, and more specifically to an auxiliary detection device for a circuit board plug-in capacitor. Background Art

[0002] PCB plug-in capacitors are electronic components installed vertically on the PCB. Generally, capacitors are installed in multiple locations on the same PCB. Since the installation locations of capacitors are irregular and there are many other electronic components on the PCB, it is generally necessary to test the plug-in capacitors installed on the PCB to avoid missing or wrong installation of capacitors on the PCB.

Since the auxiliary cover plate is a non-transparent structure, when the plug-in capacitor is installed in the wrong position on the circuit board, it will be blocked by the non-transparent auxiliary cover plate and cannot be discovered in time, which can easily affect the use effect.
