Abstract
Description
Technical Field
[0001] This utility model relates to the field of filters, and more particularly to an anti-interference power supply filter. Background Technology
[0002] Filters have many significant advantages and benefits in the field of signal processing. From the perspective of signal quality improvement, they can accurately filter frequency components, effectively improve the signal-to-noise ratio by removing noise and purifying the signal, making the audio purer and the image clearer, and ensuring the accuracy and stability of communication signals. In terms of system optimization, filters can reduce power supply ripple, reduce electromagnetic interference, ensure the stable operation of electronic equipment, and extend its service life.
[0003] Existing power filters are generally connected to other mechanisms via two mounting plates at the bottom. Over time, the through holes on the mounting plates may enlarge due to friction from the screws, reducing the mounting effect. Furthermore, since the mounting plates and the filter housing are welded together, the entire filter needs to be replaced if the mounting plates are damaged, which is very wasteful.
[0004] Therefore, those skilled in the art have provided an anti-interference power supply filter to solve the problems mentioned in the background art. Utility Model Content

[0007] The front and rear ends of the placement cover are bolted with second mounting plates. The two second mounting plates have through holes at the four corners of their front faces. The two second mounting plates are made of aluminum alloy. The outer surfaces of the second mounting plates, the placement cover, and the placement plates are all coated with silver.
[0008] Furthermore, a first mounting plate is fixedly provided on each of the two snap-fit slots on opposite sides, and the two first mounting plates are made of stainless steel.
[0009] Furthermore, multiple through holes are provided on the upper surface of both first mounting plates.
[0010] Furthermore, two first threaded holes are provided on the upper part of both the front and rear ends of the placement cover.
[0011] Furthermore, both of the two snap-fit slots have second threaded holes at their front and rear ends.
[0012] Furthermore, the front and rear ends of the filtering body are both fixedly equipped with connection modules.
[0013] Furthermore, both of the second mounting plates have a through-hole at their front ends.
[0014] This utility model has the following beneficial effects:
[0015] 1. This utility model proposes an anti-interference power filter, in which a cover can be snapped into a mounting plate. When the cover and the mounting plate are connected, they form an outer shell, in which the filter body can be placed. The mounting plate has snap-fit blocks fixed on both sides, which can snap into snap-fit slots during use. The snap-fit slots are fixed to a first mounting plate. After the above structure is installed, a second mounting plate can be installed at the front and rear of the outer shell to place the filter body inside. At the same time, the damaged structure can be replaced when the external structure is damaged. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Reference Figure 1-4 An embodiment of this utility model provides an anti-interference power filter, including a placement cover 1, a placement plate 3 snapped onto the lower end face of the placement cover 1, a filter body 2 snapped onto the upper end face of the placement plate 3, snap-fit blocks 6 fixedly disposed on both sides of the placement plate 3, snap-fit grooves 7 snapped onto the outer surfaces of the two snap-fit blocks 6, and second mounting plates 11 bolted to the front and rear ends of the placement cover 1. Through holes 13 are opened at the four corners of the front end face of the two second mounting plates 11. The two second mounting plates 11 are made of aluminum alloy, and the outer surfaces of the second mounting plates 11, the placement cover 1, and the placement plate 3 are all provided with a silver plating layer.
[0024] Specifically, the main structure of this device is a placement cover 1, which can be snapped into a placement plate 3. When the placement cover 1 and the placement plate 3 are connected, they form an outer shell, into which the filter body 2 can be placed. After the filter body 2 is installed, second mounting plates 11 can be installed at the front and rear ends of the structure, respectively. The second mounting plates 11 can keep the filter body 2 stable inside the structure. Both the placement cover 1 and the placement plate 3 are plated with a silver plating layer on their outer surfaces during use, which provides anti-interference capability when the filter body 2 is installed. Snap-fit blocks 6 are fixed on both sides of the placement plate 3. Snap-fit blocks 6 can be snapped into snap-fit slots 7 during use. Snap-fit slots 7 are connected to the first mounting plate 8, which allows the device to be connected to other structures. The first mounting plate 8 may be damaged during long-term use, and the snap-fit slots 7 allow the first mounting plate 8 to be replaced. After the snap-fit slots 7 and snap-fit blocks 6 are connected, the second mounting plate 11 can fix the two structures.
[0025] Reference Figure 1-4 Each of the two snap-fit slots 7 has a first mounting plate 8 fixedly installed on its opposite side. The two first mounting plates 8 are made of stainless steel.

The four corners of the front end of the second mounting plate 11 are provided with through holes 13. When assembling the outer shell, the through holes 13 and the first threaded holes 4 and the second threaded holes 5 need to be aligned, and fixing bolts need to be installed inside to ensure that the second mounting plate 11, the cover 1, the mounting plate 3 and the snap-fit groove 7 can be firmly connected together. The through hole 12 at the front end of the second mounting plate 11 facilitates the passage of the connection module 10 of the filter body 2 through the outer shell.
[0027] Working principle: When the placement cover 1 and the placement plate 3 are connected, an outer shell can be formed, and the filter body 2 can be placed inside. After the filter body 2 is installed, the second mounting plate 11 can be installed at the front and rear ends of the structure respectively. Through the second mounting plate 11, the filter body 2 can be kept stable inside the structure. When the placement cover 1 and the placement plate 3 of the device are used, they are both plated with a silver plating layer on their outer surfaces, so that the above device can have anti-interference ability when installing the filter body 2.
[0028] The upper surface of the first mounting plate 8 has multiple through holes 9, which can be used to place bolts to connect the device to other structures. The front and rear parts of the cover 1 are provided with first threaded holes 4, and the front and rear parts of the snap-fit groove 7 are provided with second threaded holes 5.
