Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-4, a kind of power-supply filter improves device, including shell 1, and the shell 1 is cavity structure, shell 1
Two sides be bolted dust cover 2, the two sides of shell 1 are also provided with opening 5, be open 5 inner wall it is solid by screw
Surely there is strainer 6, the side of strainer 6 is fixed with dust-proof plate 7 by rivet, and the front side of shell 1 is fixedly installed socket 3, socket 3
Be internally provided with power outlet, and the inner wall two sides of socket 3 are welded with holddown spring 8, the other end welding of holddown spring 8
There is L-type securing plate 10, L-type securing plate 10 is slidably arranged in the inside of socket 3, and dust cover 2 is located at the side of opening 5, by anti-
Dust hood 2, thermovent 4, opening 5, the isostructural setting of dust-proof plate 7, change the package assembly of conventional filter shell 1, in shell 1
