Specific embodiment
Please refer to shown in Fig. 1-5, the utility model about a kind of Flat wire vertical winding inductance, include circular magnetic core 1 and around
Group, winding is vertical to be wound on circular magnetic core 1, and the winding is multiple flatwise coils 2, and correspondence is existed side by side between multiple flatwise coils 2
It is wound on circular magnetic core 1, two adjacent 2 ends of flatwise coil are respectively equipped with the terminals 3 of connection circuit board, circular magnetic
Core 1 includes the first magnetic core 4, the second magnetic core 5, and the first magnetic core 4 is equipped with fixed gap corresponding with 5 shape of the second magnetic core, and second
The adaptation of magnetic core 5 is connected in fixed gap；
Wherein, two end faces of the second magnetic core 5 are respectively first end face 6, second end face 7, and fixed gap is respectively with first
7 corresponding two end face 6, second end face end faces are the first oblique section, the second oblique section, and second end face 7 is close to first end face 6
So that the inner arc of the second magnetic core 5 is recessed towards first end face 6 and protrude outward the extrados of the second magnetic core 5, passes through flat wire
