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.
[0018] Please see Figures 1-4As shown, a filter mounting fixture includes a housing 1 and a circuit board 2 inside the housing 1. The circuit board 2 has a filter circuit composed of capacitors, inductors, and resistors. Side ears 5 are mounted on both sides of the housing 1, and clamps 6 are engaged on the side ears 5. The side of the clamps 6 facing the housing 1 is L-shaped. The two clamps 6 are engaged with a base 7. The clamps 6 and the base 7 are limited by a limiting structure 9. The bottom end of the base 7 is provided with an adhesive layer 8. The two clamps 6 are respectively provided with positioning blocks 10 and positioning grooves 11. The positioning blocks 10 engage with the positioning grooves 11. The base 7 is pasted in the designated position by the adhesive layer 8. Then the two clamps 6 are respectively attached to the base 7. The side ears 5 on the outer shell 1 engage. When the two clamps 6 engage with the side ears 5 respectively, the positioning block 10 on one clamp 6 engages with the positioning groove 11 on the other clamp 6. After the positioning block 10 and the positioning groove 11 are aligned, the two clamps 6 are symmetrically arranged, which facilitates the engagement of the two clamps 6 with the base 7. When the clamps 6 are engaged with the base 7, the side of the clamp 6 facing the side ears 5 has a U-shaped structure. The end of the clamp 6 facing the side ears 5 is provided with a first inclined surface 12. The first inclined surface 12 facilitates the engagement of the clamp 6 with the side ears 5. The side of the clamp 6 facing the base 7 is provided with a second inclined surface 13. The second inclined surface 13 facilitates the docking of the clamp 6 with the base 7.
[0019] As a technical optimization of this utility model, the outer shell 1 is provided with a terminal block 3, which is electrically connected to the circuit board 2, and a cable 4 is connected to the terminal block 3; the cable 4 is connected to an external electrical component, and the circuit board 2 and the filter circuit composed of capacitors, inductors and resistors on the circuit board 2 effectively filter out the frequency point of a specific frequency or the frequency other than the frequency point in the cable 4 to obtain a power signal of a specific frequency.
[0020] As a technical optimization of this utility model, the limiting structure 9 includes a limiting rod 901, which is slidably mounted on the base 7. The limiting rod 901 engages with the positioning block 10. A push plate 903 is fixed on the limiting rod 901, and the push plate 903 is slidably connected to the base 7. A spring 902 is fixed between the push plate 903 and the base 7. The end of the limiting rod 901 facing away from the positioning block 10 is U-shaped, and the positioning block 10 has a hole 904.
