Description

Technical Field

[0001] This utility model belongs to the field of waterproof filter technology, specifically relating to an anti-interference filter with waterproof function. Background Technology

[0002] In the rapid development of modern electronic technology, filters, as a key electronic component, are widely used in many fields such as communications, power, and electronic equipment. Their main function is to filter and process signals, remove noise and interference, and ensure accurate signal transmission and stable operation. However, with the continuous expansion and increasing complexity of application scenarios, filters face many severe challenges, among which waterproofing and anti-interference issues are particularly prominent.

[0003] In many practical applications, filters inevitably come into contact with moisture. For example, in outdoor communication base stations, filters need to be exposed to the natural environment for extended periods, enduring the erosion of rain and humid air; in industrial production workshops, there may be water vapor and liquid splashes. Once moisture enters the filter, it will damage its internal electronic components, causing short circuits and corrosion, thereby affecting the filter's performance, shortening its lifespan, and even rendering the entire electronic device malfunction, causing significant inconvenience and losses to production and daily life. Therefore, this application proposes a waterproof anti-interference filter. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] This embodiment provides a waterproof anti-interference filter, the structural diagram of which is shown below. Figures 1-6 As shown, it includes the filter body 1, the base plate 2, and the housing 3.

[0027] In this embodiment, the base plate 2 is horizontally attached to the bottom of the filter body 1, and the shell 3 is placed on top of the filter body 1. The shell 3 is attached to the upper surface and two sides of the filter body 1. The shell 3 is connected to the base plate 2. The shell 3 and the base plate 2 provide good protection for the filter body 1. Both the shell 3 and the base plate 2 are made of metal. Metal has good shielding performance and can effectively block external electromagnetic interference signals from entering the filter body 1. At the same time, it can also prevent electromagnetic signals inside the filter body 1 from leaking to the outside, thereby achieving the function of anti-interference.

[0028] Furthermore, a sealing gasket 12 is sandwiched between the bottom plate 2 and the bottom of the filter body 1. The bottom plate 2 has raised strips 10 on both sides, which are distributed along the length of the bottom plate 2. A pair of raised strips 10 are arranged opposite each other, and the sealing gasket 12 is laid between the pair of raised strips 10. The bottom end of the filter body 1 is embedded between the pair of raised strips 10, so that the bottom of the filter body 1 is tightly fitted with the sealing gasket 12. At this time, the sealing gasket 12 plays a preliminary sealing role to prevent moisture from entering the interior from the connection between the filter body 1 and the bottom plate 2.

[0029] Furthermore, a housing 3 is placed on top of the filter body 1. The housing 3 fits snugly against the upper surface and two sides of the filter body 1, while the bottom end of the side wall of the housing 3 is inserted between the protrusion 10 and the filter body 1. The two ends of the housing 3 extend through, and a first sealing strip 11 is provided at both ends of the inner wall of the housing 3. The first sealing strip 11 is sandwiched between the surfaces of the housing 3 and the filter body 1, further enhancing the sealing at the connection between the housing 3 and the filter body 1 and preventing moisture from seeping in through the gap.

[0030] Furthermore, a retaining strip 4 is provided at the bottom of the outer wall of the housing 3, and the retaining strip 4 is distributed along the length of the housing 3. When the bottom of the side wall of the housing 3 is inserted between the protrusion 10 and the filter body 1, the retaining strip 4 blocks the gap between the protrusion 10 and the housing 3. The cross-section of the retaining strip 4 is an inverted "L" shape, and a fitting cavity 15 is formed between the retaining strip 4 and the side wall of the housing 3. At this time, the second sealing strip 14 provided on the protrusion 10 is tightly embedded in the fitting cavity 15, further improving the overall waterproof performance.

[0031] Furthermore, a connecting flange 5 is horizontally positioned at the bottom of the side of the clip 4 furthest from the housing 3, and the connecting flange 5 is horizontally fitted to the base plate 2. A connecting screw 6 passes through the connecting flange 5, and a connecting hole 13 is provided on the base plate 2 to match the thread of the connecting screw 6. By screwing the connecting screw 6 into the connecting hole 13, a stable connection is achieved between the connecting flange 5 and the base plate 2, thereby firmly fixing the housing 3 to the base plate 2 and ensuring the structural stability of the entire filter.

[0032] Furthermore, in this embodiment, vertical plates 7 are vertically arranged at the four corners of the bottom of the base plate 2. The bottom end of the vertical plate 7 is horizontally bent to the outside of the base plate 2 to form mounting ears 8, and mounting holes 9 are provided on the mounting ears 8. The anti-interference filter can be conveniently installed on other equipment or structures through the mounting holes 9.

[0033] Working principle:

[0034] During operation, both the base plate 2 and the housing 3 are made of metal. Metal has good shielding performance, which can effectively block external electromagnetic interference signals from entering the filter body 1. At the same time, it can also prevent electromagnetic signals inside the filter body 1 from leaking to the outside, thereby achieving the function of anti-interference.

[0035] In terms of waterproofing, the sealing gasket 12 is located between the filter body 1 and the base plate 2, the first sealing strip 11 is located between the housing 3 and the filter body 1, and the second sealing strip 14 is located between the retaining strip 4 and the protruding strip 10, together forming a multi-layer sealing structure. These sealing components can prevent moisture penetration and ensure that the filter body 1 is in a dry working environment, thereby ensuring its normal operation.

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
