The thickness direction of the coil is the same as the second direction Y, and the thickness direction of the first baffle 120 and the second baffle 130 is the same as the second direction Y. By setting the thicknesses of the first baffle 120 and the second baffle 130 to be greater than the thickness of the coil, the folding and connecting of the first skeleton 100 and the second skeleton 200 is facilitated, the difficulty of folding and splicing is reduced, and after the first skeleton 100 and the second skeleton 200 are folded and connected, there is a gap between the coil of the first skeleton 100 and the coil of the second skeleton 200, the risk of short circuit of the coils on the two skeletons is reduced, and the reliability of the magnetic device is further improved.

By arranging the isolation plate 140, a plurality of coils on the same bobbin 110 can be isolated and protected, the risk of the coils being extruded is reduced, and the reliability of the magnetic device is further improved.
[0033] In an embodiment, the thickness of the isolation plate 140 is less than the thicknesses of the first baffle 120 and the second baffle 130, so that when the first skeleton 100 and the second skeleton 200 are folded and connected, there is a gap between the isolation plate 140 of the first skeleton 100 and the isolation plate 140 of the second skeleton 200, and the reliability of the magnetic device is further improved.
[0034] In an embodiment, the first baffle 120, the second baffle 130, and the bobbin 110 are integrally formed, which reduces the risk of unstable connection between the first baffle 120, the second baffle 130, and the bobbin 110 due to gaps, and further improves the reliability of the magnetic device.
