Two annular plates 17 are fixedly installed on the circular through hole 3, and dustproof nets 18 are fixedly installed in the two annular plates 17 respectively. The dustproof nets 18 prevent external dust from entering the distribution cabinet body 1 and adhering to the components in the distribution cabinet body 1, thereby affecting the service life of the components.
