Description

Technical Field

[0001] This utility model relates to the field of inductor technology, specifically to an inductor with shielding function. Background Technology

[0002] An inductor with shielding function is an electronic component that suppresses electromagnetic interference through a special structural design. Its core feature is the use of magnetic shielding or electromagnetic shielding technology, which uses shielding materials to absorb or reflect external electromagnetic waves, while preventing its own magnetic field from interfering with other components, effectively limiting the spread of the magnetic field and resisting external interference.

[0003] Chinese patent CN218038823U discloses an inductor with shielding function, comprising pins, a coil, and a core. A fixing block is provided at the top of the pin, and a heat dissipation structure is provided inside the fixing block. The core is fixed at the top of the fixing block, and the coil is fixed at the top of the pin. A magnetic shielding structure is provided outside the coil. The magnetic shielding structure includes a nickel alloy shell, an adhesive layer, and an aluminum film. The aluminum film is disposed outside the coil, and the adhesive layer is disposed outside the aluminum film. The nickel alloy shell is disposed outside the adhesive layer. A reinforcing structure is provided inside the core. This invention provides external interference protection for the coil by providing a magnetic shielding structure. During use, the coil may be subject to external magnetic interference. In this case, the nickel alloy shell can protect the coil from interference by blocking magnetic signals. The adhesive layer fixes the aluminum film inside the nickel alloy shell, thus achieving external interference protection for the coil.

[0004] The aforementioned device reinforces the inductor body. However, in the use of existing devices, the connection between the shielding shell and the inductor body is relatively fixed, making it difficult to install or remove the shielding shell from the inductor body. This not only affects the inductor assembly speed but also makes the inductor body difficult to repair. Furthermore, the connection method between the shielding layer and the shell also makes it difficult to disassemble and install the inductor. Therefore, it is necessary to provide an inductor with shielding function. Utility Model Content
