Technical Field

[0001] This utility model belongs to the field of filter protection technology, and in particular relates to a filter protection structure. Background Technology

[0002] In electronic devices, filters play a crucial role. They can filter signals of specific frequencies, removing unwanted frequency components, thereby ensuring signal quality and stability.

[0003] However, in practical applications, filters often face various potential threats and challenges. On the one hand, electromagnetic interference in the external environment can damage filters. For example, strong electromagnetic interference may cause filter performance degradation or even complete failure. On the other hand, in real-world devices, heat sinks may come into contact with the filter's internal circuitry, causing short circuits in electronic components and thus damaging the filter. Additionally, mechanical shocks and vibrations during use can damage the filter's internal structure. Utility Model Content

[0025] like Figure 1-2 As shown, a filter protection structure includes a housing 1, a base 2, and a cover 3. The base 2 is snapped into the bottom of the housing 1, the cover 3 is sleeved on the upper end of the housing 1, and a fixing component 4 is disposed inside the housing 1 to ensure the stability of the filter within the structure. It also includes a protection component 5 disposed on the side of the housing 1 to ensure heat dissipation and electromagnetic interference protection. A power terminal 6 is fixedly connected to the upper part of the base 2.

[0026] The cover 3 has a sealing gasket 1 on the inner side of its lower end, and a sealing gasket 2 on the upper edge of the base 2. A positioning post 7 is fixed to the inner corner of the shell 1. The positioning post 7 has a positioning hole 8 through it. The upper part of the cover 3 has a positioning hole 9 that communicates with the positioning hole 1. The upper part of the base 2 has a positioning hole 10 that communicates with the positioning hole 8. Positioning plates 11 are symmetrically fixed to the side of the base 2. Positioning plates 11 have positioning holes 12. The modular design facilitates disassembly and replacement of parts.

[0027] like Figure 3-4 As shown in Figure 5, the fixing component 4 includes bracket 13, bracket 2 14 and pressing block 15. Several brackets 13 are locked inside the housing 1, and several brackets 2 14 are locked inside the housing 1. The brackets 13 and brackets 2 14 are interlocked with each other. Several locking grooves are opened at the lower ends of the brackets 13 and brackets 2 14. The pressing block 15 is fixed to the upper end of the base 2.

[0028] The pressing block 15 is fitted to the inner side of the housing 1. The base 2 is tightly connected to the housing 1 by a fixing bolt 1. The cover 3 is tightly connected to the housing 1 by a fixing bolt 2. The bracket 13 and bracket 2 14 are made of plastic. The filter may be subjected to mechanical shocks and vibrations during use. Under the mutual clamping action of the bracket 13 and bracket 2 14 that are interlocked in the fixing component 4 and the pressing block 15 at the upper end of the base 2, the filter can withstand a certain degree of impact and vibration.

[0029] like Figure 5-6As shown, the protection component 5 includes a partition 16, which is snapped onto the inner wall of the housing 1. The partition 16 and the inner wall of the housing 1 form a closed protective cavity. The outer wall of the housing 1 is provided with heat dissipation grooves 17. The heat dissipation grooves 17 are in several groups and are distributed at intervals along the central axis of the housing 1. The arrangement of heat dissipation grooves 17 on the outer wall of the housing 1 increases the heat dissipation area and effectively improves the heat dissipation effect of the filter during operation. While improving the heat dissipation effect, it ensures the airtightness of the filter and ensures that the heat dissipation structure does not affect the performance and stability of the filter.

[0030] The protective cavity is filled with shock-resistant material. The closed protective cavity formed by the partition 16 in the protective component 5 and the inner wall of the housing 1, along with the shock-resistant material inside, enhances the shock resistance of the filter. The housing 1, cover 3, base 2, and pressing block 15 are made of metal. The use of metal materials for the housing 1, cover 3, base 2, and pressing block 15 reduces the impact of external interference on the filter performance.
