Description

Technical Field

[0001] The utility model relates to the technical field of inductor components, in particular to an inductor component capable of shielding an inductor. Background Art

[0002] The inductor component is a commonly used electronic component in electronic products. It blocks the alternating current through the internal winding group, thereby producing a filtering and voltage stabilizing effect on the entire circuit. However, during the filtering process of the internal winding group, the winding group will generate heat accordingly. Long-term high-frequency use will cause heat accumulation, which will cause the magnetism of the iron core in the winding group to fade, affecting the filtering effect. In severe cases, the winding group may also cause high temperature to melt, causing damage to the inductor component.

[0003] The patent document with the prior art publication number CN116313443A provides an inductor component of a shielded inductor, including a heat dissipation device, the heat dissipation device includes a substrate, a first heat conductive plate and a heat dissipation plate, which can conduct heat and dissipate heat inside the inductor component; the adjustment device includes a vacuum tube, a first terminal, a floating plate, a second terminal, a first winding group, a second winding group and an iron core, which can adjust the resistance of the winding group coil in the inductor component, thereby changing the filtering efficiency and heating efficiency of the inductor component; the shielding device includes a shell, a second heat conductive plate, a liquid storage tank and a flow channel, which can isolate electromagnetic interference inside and outside the shielding shell.

[0004] However, during the use of the existing shielded inductor inductor component, although the electromagnetic coil is installed in a closed box made of shielding material to play a shielding role, the coil may burn out and other faults during the use of the inductor. When damage occurs, the inductor can only be replaced as a whole, and the coil cannot be replaced separately, resulting in a high maintenance cost of the inductor. For this reason, we propose an inductor component that can shield the inductor. Utility Model Content
