AI Technical Summary
Technical Problem
The interfaces of existing power filters are prone to dust accumulation and damage, and crosstalk coupling is easily formed between the power supply and the signal, reducing the electromagnetic compatibility of the system.
Method used
A power input line shielding structure is designed, and the two baffles are moved to each other through four springs to form a closed space, shielding the output port of the filter main body, and applying shielding paint to the interior wall of the chamber through a metal sheet to improve the shielding efficiency.
Benefits of technology
It effectively avoids damage to the output port of the filter body, extends the service life, and improves the anti-interference ability and electromagnetic compatibility of the equipment.

Abstract
The invention discloses a power input line shielding structure of a power filter, and relates to the technical field of filters. The filter comprises a bottom shell, a cover plate, a dustproof assembly and a filter main body, the cover plate is fixedly connected to the top of the bottom shell, the filter body is installed in the bottom shell, the dustproof assembly is arranged outside an output port of the bottom shell, two radiators are arranged in the bottom shell, and four fixing bases are arranged at the bottom of the bottom shell. The dustproof assembly comprises a sliding seat, four check blocks are fixedly connected to the inner side of the sliding seat, the two check blocks are close to the upper edge and the lower edge of the sliding seat respectively, two baffles are slidably connected into the sliding seat, two sliding grooves are formed in the ends, away from each other, of the two baffles, and springs are installed in the four sliding grooves. The two baffles are pushed by the four springs to move oppositely to form a closed space, the output port of the filter body can be shielded, the output port of the filter body is prevented from being directly exposed in air and damaged by accumulated dust, and the service life of the filter body is prolonged.
