2. Description of the Related Art FIG. 4 is a perspective view showing a conventional coil. FIG. 4A shows a conventional vertical coil, and FIG. 4B shows a conventional horizontal coil. As shown in FIG. 4A, a terminal block 4 with pins used for a conventional vertical coil is integrated with a terminal portion 5A, and has a pin 6 integrated with a pin 8 at the terminal portion 5A. . Further, the terminal block 4 with pins has a mounting portion 15 for mounting the toroidal core 1. The mounting portion 15 is provided with a claw 7 in a cylinder having a split groove 14 for fixing the core 1. In a conventional coil, a copper wire 2 is wound around a toroidal core 1 and a lead wire 3 is connected to a toroidal coil 13.
And the torsion coil 13 is attached to the terminal block 4 with pins. As shown in FIG. 4B, in the conventional horizontal toroidal coil, the toroidal core 1 is mounted on the mounting portion 15 of the terminal block with pins, and the pin terminal block 4 is mounted on the substrate, similarly to the vertical coil described above. The pins 6 of the terminal portions 5B are mounted so as to be at right angles to the pin terminal block 4 so as to be mounted laterally. Conventionally,
When mounting this type of coil on a board, the lead wire is fixed with solder, and in the case of a thin wire, it is unstable with respect to the risk of disconnection and the board, and depending on the installation location, it may be vertical or horizontal. There was a disadvantage that a terminal block had to be prepared.

[0003]

SUMMARY OF THE INVENTION In order to eliminate these drawbacks, the present invention secures the mountability on a board and also facilitates two types of mounting, a vertical type and a horizontal type, with one pin terminal block. The purpose is to provide.

[0004]

SUMMARY OF THE INVENTION The present invention is to provide a divided terminal portion which is separated from a terminal block into which a pin is press-fitted into a terminal block, and fits the divided terminal portion with a fixing engagement mechanism provided on the terminal block. Thus, the direction of the pins is set to a direction suitable for vertical or horizontal mounting. By attaching the lead wires to the pins, it is possible to secure the mounting property on the board. By changing the direction of the divided terminals with one divided terminal, the vertical or horizontal mounting can be performed with one terminal block. Can be shared.

That is, the present invention provides a toroidal coil wound on a terminal block having a pin comprising a claw provided on a cylinder having a split groove, a mounting portion for mounting a toroidal core, and a terminal portion having a pin integrated with a barbacle pin. In the coil assembled with the core, the terminal part is separated from the terminal block to form a divided terminal part, and an engagement mechanism that can fix the divided terminal part and the terminal block is provided by fitting the divided terminal part and the terminal block. , If desired
The coil is characterized in that it can be made vertical or horizontal.

[0006]

The conventional terminal block with a pin used for a toroidal coil has a terminal block and a terminal portion integrated with each other, and the vertical terminal block with a pin for a toroidal coil is a vertical dedicated terminal block with a pin for a toroidal coil. The horizontal terminal block with toroidal coil pins used is a horizontal terminal block with dedicated toroidal coil pins, and the toroidal coil is mounted on the board. In the present invention, the vertical and horizontal terminal portions having pins attached thereto are separated from the terminal block, the separated portions are used as split terminal portions, the pins are press-fitted into the split terminal portions, and the split engagement portion is used as a fixing engagement mechanism. By providing a fitting protrusion on the terminal portion and a fitting recess on the terminal block, and fitting the fitting protrusion on the split terminal portion and the fitting recess on the terminal block, the vertical and horizontal split terminal portions can be used as terminals. Provided is a coil using a terminal block with pins that can be fixed to a base and can be mounted vertically or horizontally on a substrate with one terminal block and one divided terminal portion as desired.

FIG. 3 is an exploded perspective view of a coil according to the present invention. The coil of the present invention is obtained by winding a copper wire 2 around a toroidal core 1 and mounting it on a terminal block with pins. The pin-attached terminal block 4 includes a mounting projection 16 having a claw 7 for holding an inner peripheral surface of the toroidal coil 13 and a split groove 14, a mounting portion 15, a divided terminal 5, and a pin. The two lead wires 3 of the toroidal coil are tied to the tie pins 8, soldered, the inner peripheral surface of the core 1 is fitted to the claws 7 of the mounting projections 16, and the toroidal coil 13 is mounted to the mounting portion 15. It is fixed. FIG. 3 shows a vertical terminal block 4 with pins for toroidal coils.
2 shows a method of joining the toroidal coil 13. Note that the split terminal portion 5 has already been fitted.

FIG. 1 is an exploded perspective view of parts of a terminal block with pins used in the coil of the present invention. In FIG. 1, the terminal block with pins can use both a vertical divided terminal portion 5 and a horizontal divided terminal portion 11. In the terminal block with pins for a vertical coil, the vertical split terminal portion 5 has a plurality of pins,
At both ends of the separated divided terminal portion 5, fitting protrusions 9 to be fitted to the terminal block 4 are provided, fitting recesses 10 are provided inside the terminal block 4, and the fitting protrusions 9 are fitted to the fitting recesses 10. It is intended to be fitted. In FIG. 1, the terminal block with pins for a horizontal coil has a fitting concave portion 10 of the terminal block 4 and a fitting convex portion 12 of the divided terminal portion 11 fitted thereto.

FIG. 2A is a perspective view of a vertical coil. FIG. 2B is a perspective view of a horizontal coil.
