る。 As shown in FIG. 5, a conventional small coil has a pot-shaped core in which a winding core 10 is integrally erected at the center of the interior and two corresponding notch windows 11 are provided on the outer periphery. The members 12, 12 are assembled by butting each other, and conductive parts 13, 1 are provided at both ends on the bottom surface of one of the core members 12, 12.
3 and the notch windows 11, 11 of the core member are inserted, the terminal board 14 is inserted, the coil 15 is inserted, and the two core members 12, 12 are fixed facing each other. . Further, as shown in FIG. 6, a coil 17 is wound around a drum-shaped core 16, and a curved magnetic alloy material 19 having outwardly cut and raised portions 18, 18 on the outer peripheral end surface is attached to the drum-shaped core 16.
The coil leads 21, 21 are pulled out from the gap 20 of the opposing magnetic alloy material 19 and the coil leads 21, 21 are soldered to the side end portion 22 of the magnetic alloy material 19. are connected and fixed to form an electric circuit.
This small coil uses cut and raised portions 18, 18 on the end face of the magnetic alloy material 19 as printed circuit connection portions.

なる。 However, in the small coil shown in FIG. 5, the conductive parts 13 and 13 of the terminal board 14 are provided with copper foil on the top and bottom surfaces of the insulating base material, so even if the coil leads are wrapped and wired and soldered, there is no insulation. It is difficult to solder to the base material part, and soldering to the circuit-connecting copper foil part of the printed circuit board becomes a problem. or,
When used in products with limited installation space, such as wristwatches and desktop computers, the installation space and position are limited, and the terminal board 14 of the small coil described above is an insulating base material, so the printed circuit connection parts 13, 13 can be freely connected. There is a drawback that it cannot be set at the desired position. Furthermore, since the core members 12, 12 are butted together, precision of the butting surfaces is required for performance, which increases the cost.

高価となるものであつた。 Moreover, the small coil shown in FIG. 6 is made of magnetic alloy material 1.
9, when soldering the coil leads 21, 21, the wettability of the solder varies due to variations in materials and processing lots, making uniform soldering difficult. A similar problem occurs when soldering with the foil portion, and as a result, it becomes necessary to partially plate the soldered portion (with silver, solder, etc.), which increases the cost. Also, when the coil leads 21, 21 attach and fix the magnetic alloy material 19 to the drum-shaped core 16, the coil leads 21, 21 are attached to the magnetic alloy material 19.
When they are closely fixed facing each other, cutting or adhesive fixing is difficult, resulting in poor productivity and high cost.

As shown in Figure B, the opposite ends of the core 1
The protrusion protrudes from the end and is bent in an arbitrary direction. As shown in FIG. 1C, a coil 4 is wound around a drum-shaped core 1, and coil leads 5, 5 at both ends are wound around terminals 3, 3, respectively, and wired and soldered. As shown in FIG. 1D, 6 is a substantially cylindrical magnetic alloy material provided with a gap 7, and has a cutout window 8 on the side surface corresponding to the gap 7. As shown in FIG.
Gap portion 7 or cutout window portion 8 of this magnetic alloy material 6
so that the protruding ends of the terminals 3, 3 fit together,
As shown in FIG. 1E, the drum-shaped core 1 with the coil 4 wound thereon is finished so that the inner diameter b of the magnetic alloy material 6 is smaller than the outer diameter a of the end face of the drum-shaped core 1 (a>b). The inner diameter dimension b of 6 is the drum type core 1
Insertion and fitting are performed with the outer diameter of the end face wider than the outer diameter a (a<b), and using the restoring force of the magnetic alloy material 6, pressure is applied to the end face side of the drum-shaped core 1, and adhesive, etc. is applied from the gap part 7. is fixed. A cross-sectional view of this completed product is shown in FIG. In addition, this restoring force is
The restoring force can also be adjusted by arbitrarily setting the dimension c. FIG. 4 shows a connecting terminal formed by integrally providing multiple sets of terminals 3, 3, which can improve workability compared to a single terminal.

し信頼性が高い等の優れた効果を有する。 As mentioned above, the small coil according to the present invention allows for free homing of the terminals, reducing the installation space and easing the installation location conditions.Furthermore, since the terminals protrude in different directions, it is easy to mount the terminals on a printed circuit board. This eliminates the risk of short circuits caused by solder, making the assembly extremely reliable, and compared to conventional products, there is no insulating base material on the terminal board, so there are no problems when soldering to the printed circuit board. Additionally, there are no problems with solder wettability or coil lead processing, making automatic winding, wiring, etc. easy to automate, and the magnetic circuit has a structure similar to a closed magnetic circuit, making it possible to achieve high inductance. Furthermore, the inductance can be freely set by setting the dimensions of the cutout window and gap, making it suitable for mass production and highly reliable.
