Description

Technical Field

[0001] The utility model relates to the technical field of power supply filters, in particular to a power supply filter which is easy to assemble and disassemble. Background Art

[0002] The power supply filter is a filter circuit composed of capacitors, inductors and resistors. The filter can effectively filter out a specific frequency point in the power line or frequencies other than the frequency point to obtain a power supply signal of a specific frequency, or eliminate a power supply signal after a specific frequency.

[0003] In the prior art, the patent document with announcement number CN217216358U proposes a power filter that is easy to disassemble and assemble, including a housing and a protective cover, wherein the upper surface of the housing is embedded with a protective cover, and the two side surfaces of the housing are movably embedded with folding push rods near the upper side, and the four corners of the housing are movably installed with mounting blocks. The power filter that is easy to disassemble and assemble described in the utility model can be conveniently disassembled by arranging a protective cover, a housing and a folding push rod to cooperate with each other, and the folding push rod is pushed into the interior of the housing. When the folding push rod is pushed into the interior of the housing, the rear end of the folding push rod will push the locking block out of the locking groove. When the locking block exits the locking groove, the protective cover can be opened. By providing a mounting block that can be adjusted in position, the filter can be installed in different installation environments. By rotating and removing the fastening screws, the position of the mounting block can be adjusted. When the mounting block is moved to the required position, the mounting block is fixed again with the fastening screws.

However, there is still a situation that the filter cannot be adapted to different mounting sockets during the installation process, which reduces the practicality of the filter.
