[0002] Existing high-power, high-current, high-power, and high-current choke coils generally include a ring-shaped magnetizer and a coil winding surrounding the ring-shaped magnetizer. It is circular, and with the different number of strands of enameled wire, the cross section of the lead-out part and the size of the circle are different. In this way, when the pin power board of the high-power and high-current choke coil is inserted and welded, the power board The reserved hole is not easy to control. If the aperture is small, the pin cannot be inserted for soldering. If the hole is large, tin leakage will occur during soldering. In addition, this irregular circular pin has a large cross-section. It is not easy to penetrate through welding, and there will be false connections; at the same time, it is also laborious to trim at the end, and it is not easy to cut off

Embodiment Construction
[0010] The present invention will be further described below in conjunction with the accompanying drawings.
[0011] Such as figure 1 Shown is a high-power and high-current choke coil, including a ring-shaped magnetizer 1 and a coil winding wrapped around the ring-shaped magnetizer. The coil winding is formed by twisting more than three enameled wires 2; the lead-out part 3 of the coil winding is each strand The enameled wires 2 are arranged in parallel and connected to form a flat plate; the outer surface of the ring magnet is coated with an insulating layer.
[0012] The above is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, some improvements and modifications can also be made, and these improvements and modifications are also possible. It should be regarded as the protection scope of the present invention.

The invention discloses a high-power high-current choking winding which comprises an annular magnetizer and a coil winding which is wound around the annular magnetizer, and is characterized in that the coil winding is formed by stranding more than three strands of enameled wires; and the lead-out part of the coil winding has a flat plate shape formed by arranging and connecting each strand of enameled wires one by one. According to the high-power high-current choking winding, the lead-out part of the coil winding is of a flat plate shape formed by arranging and connecting each strand of enameled wires one by one, so that the choking winding is easily cut off during shearing, the pin has controllable height and width, a reserved hole on a power board is arranged to have a rectangular shape close to the diameter of the enameled wires, and the high-power high-current choking winding is easily inserted and welded, easy in through welding and firm in welding.
