Description of the Related Art In a choke coil used for smoothing the output of a switching power supply, since its output current is large, a wire having a large wire diameter is used to suppress the DC resistance component as low as possible. 2A and 2B are perspective views showing a configuration of a conventional large current choke coil, in which FIG. 2A shows a state without winding, and FIG. 2B shows a state in which a winding is wound. In the figure, the coil bobbin 6 includes a winding core 7,
It is composed of a collar portion 3 that covers both ends of the winding core 2 and a terminal pin 4 that fixes the collar portion 3 and the printed circuit board. Further, the winding wire 5 having a large diameter is wound around the surface of the winding core 7 in a single layer, and it is difficult to entangle the winding wire 5 having a large diameter with the terminal pin 4. The ends are configured to connect directly to the printed circuit board.

くなる問題点があった。However, in the conventional bobbin as described above, since the wire diameter of the winding wire to be wound is large, the winding wire 5 is unevenly wound and a gap 8 is formed between the winding wires as shown in FIG. There were cases. This is because the winding work is performed relying on the experience and intuition of the worker, and therefore an unfamiliar worker creates a gap between the windings and shifts the position to the connection point on the printed circuit board, In some cases, the winding of a predetermined length may not be able to be wound in a single layer, and when a winding having a large wire diameter is used, there is a problem that variations in winding work become large.

Since a large diameter winding is wound along this, the winding can be evenly wound regardless of the operator.

FIG. 1 is a perspective view showing the structure of a coil bobbin according to the present invention. In the figure, a bobbin 1 includes a winding core 2 with a groove, and a collar portion 3 that covers both ends of the winding core 2 with a groove.
It is composed of the flange portion 3 and a terminal pin 4 for fixing the printed circuit board. Particularly, the grooved winding core 2 has a spiral groove on the surface thereof, and the shape of the groove is V-shaped or U-shaped, and the groove interval is set according to the diameter of the winding. There is.

ント板上への接続点位置も正確なものとなる。When winding a large-diameter winding around the grooved bobbin configured as described above, it suffices to wind the winding along this groove, so that the winding can be wound evenly without any gap between the windings. Since the positions of the winding end portions of the winding start and winding end are stable, the position of the connection point on the printed board is also accurate.

低価格化を図る上で著しい効果を有する。As described above, according to the present invention, the bobbin is provided with the groove as described above, so that a person performing a winding operation can uniquely determine the winding position, and thus the variation of the product is eliminated, so that the efficiency and accuracy of the operation can be improved. It has a remarkable effect in improving the price and further reducing the price of the product.
