[0023] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0024] Please refer to Figures 1-4 The utility model discloses an anti -interference inductance, including bottom plate 1, inductance body 3 and protection shell 4, inductance body 3 is fixed at the upper end of bottom plate 1, be equipped with bottom groove 2 in bottom plate 1, the bottom end of protection shell 4 is inserted to the inside of bottom groove 2 and is connected with bottom plate 1 screw thread,
[0025] Inductance body 3 is composed of core 10 and winding 11, winding 11 is wound on the outer wall of core 10, and a first shielding layer 12 is arranged between the core 10 and the winding 11, and a second shielding layer 13 is arranged on the outer wall of the winding 11.
[0026] The top of the protection shell 4 is provided with an opening, and the opening is provided with a top cover 7. The lower end of the top cover 7 is provided with a top block 9 inserted into the opening. The top block 9 is threadedly connected with the protection shell 4. The protection shell 4 is filled with shielding material around the inductance body 3.
[0027] When the anti-interference inductance works, the winding 11 in the inductance body 3 is wound on the outer wall of the core 10, and plays a role of filtering and oscillation in the circuit. Since the first shielding layer 12 is arranged between the core 10 and the winding 11, and the second shielding layer 13 is arranged on the outer wall of the winding 11, the two shielding layers can preliminarily block the influence of external electromagnetic interference on the winding 11 and the core 10, reduce the damage of electromagnetic interference to the normal work of the inductance, and the first shielding layer 12 and the second shielding layer 13 can be made of conductive paint. The conductive paint is a coating with conductive properties, which can be directly coated on the surface of the winding 11 to form a shielding layer. It is convenient to construct, can better adapt to the complex shape of the winding 11, and can form a continuous conductive film after drying, which can shield electromagnetic interference. At the same time, the protection shell 4 is filled with ferrite material as shielding material around the inductance body 3. The ferrite material has high magnetic permeability and can effectively absorb and suppress electromagnetic interference signals. When the external electromagnetic interference signals pass through the protection shell 4, part of them are blocked by the protection shell 4, and the other part of the interference signals entering the protection shell 4 are absorbed and attenuated by the ferrite shielding material, thereby further reducing the influence of electromagnetic interference on the inductance body 3, ensuring stable transmission and processing of signals in the circuit, and making the circuit work more stably.
[0028] In the embodiment, anti-skid lines are arranged on the outer wall of the protection shell 4.
[0029] In the embodiment, the shielding material is made of ferrite material.
[0030] Install the inductance body 3: fix the inductance body 3 at the upper end of the bottom plate 1 to ensure that the inductance body 3 is firmly installed.
[0031] In this embodiment, the bottom of the protective shell 4 is provided with a limiting ring 5, the limiting ring 5 is located on the periphery of the protective shell 4, and the limiting ring 5 is located at the upper end of the bottom plate 1. The lower end of the limiting ring 5 is provided with a sealing ring 6 that contacts the bottom plate 1.
[0032] 2) Install the protective shell 4: Align the bottom end of the protective shell 4 with the bottom groove 2 inside the base plate 1. Since the protective shell 4 is threadedly connected to the base plate 1, rotate the protective shell 4 to gradually insert its bottom end into the bottom groove 2 and connect it tightly until the protective shell 4 is installed in place. At this time, the limiting ring 5 at the bottom of the protective shell 4 is located at the upper end of the base plate 1, and the sealing ring 6 at the lower end of the limiting ring 5 contacts the base plate 1 to play a sealing role.
[0033] 3) Filling with shielding material: After the protective shell 4 is installed and the inductor body 3 is inside the protective shell 4, fill with ferrite shielding material around the inductor body 3 to ensure that the shielding material is evenly filled around the inductor body 3.
[0034] In this embodiment, the top of the top cover 7 is provided with a toggle block 8;
[0035] 4) Install the top cover 7: Align the top block 9 at the bottom of the top cover 7 with the opening at the top of the protective shell 4. Since the top block 9 is threadedly connected to the protective shell 4, rotate the toggle block 8 on the top cover 7 to gradually insert the top block 9 into the opening and make a tight connection until the top cover 7 is installed in place, thus completing the assembly of the entire inductor.
[0036] By setting the first shielding layer 12, the second shielding layer 13, and filling with ferrite shielding material, a multi-layer shielding structure is formed, which effectively blocks and absorbs external electromagnetic interference, greatly improves the anti-interference capability of the inductor, reduces the interference of signal transmission and processing, and ensures the stability of circuit operation.
[0037] The anti-slip texture on the outer wall of the protective shell 4 allows for better force application when disassembling the protective shell 4, making disassembly easier; the toggle block 8 on the top of the top cover 7 facilitates rotation operation when installing the top cover 7, making the assembly of the top cover 7 more convenient.
[0038] The limiting ring 5 at the bottom of the protective shell 4 and the sealing ring 6 at the lower end of the limiting ring 5 can effectively prevent external dust, moisture and other substances from entering the interior of the protective shell 4, protect the inductor body 3 and extend the service life of the inductor.
[0039] The inductor body 3 is fixed on the base plate 1, the protective shell 4 is threaded to the base plate 1, and the top cover 7 is threaded to the protective shell 4. This connection method makes the entire inductor structure stable and not easy to loosen.
