[0024] Specifically, in this embodiment, the scheme mainly includes a mounting base 1, a soundproof shell 2 and an adjustment component; the adjustment component includes a plurality of partition plates 301 arranged in parallel between the inner cavities of the soundproof shell 2, and the plurality of partition plates 301 are slidably matched with the soundproof shell 2; a plurality of the partition plates 301 are pierced with through holes 302 for connecting filters to each other; a cavity for accommodating the filter is formed between every two adjacent partition plates 301; a power interface 303 and a load interface 304 are arranged on the outside of the soundproof shell 2, and the power interface 303 and the load interface 304 are electrically connected to the corresponding filters respectively; the mounting base 1 serves as the bottom support structure of the filter, providing a stable foundation for the entire filter, and by providing a slidable partition plate 301, the spacing between the cavities can be adjusted to achieve the adjustment of the position of the filter, so that the filter can be flexibly adjusted according to actual application requirements to meet different power filtering requirements, and the power signal can enter the filter through the power interface 303, and after being filtered by the filter, it is output through the load interface 304.

[0025] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the soundproof shell 2 includes: a plurality of return springs 201 arranged on the inner wall of the soundproof shell 2, and dampers are arranged in the plurality of return springs 201; and a soundproof pad 202 is arranged on the side of the plurality of return springs 201 away from the soundproof shell 2.
