Conventionally, this type of insulating case has a structure that only covers the core, and in horizontal cases where the outer peripheral surface of the core is placed parallel to the board, the windings are exposed on the outer peripheral surface, and in order to prevent this, post-processing is necessary. The copper wire was protected by wrapping tape around the outer surface. In addition, if there were many turns, there was a risk of miscounting the number of turns.

In order to eliminate these drawbacks, the present invention has a cylindrical body, for example, integrally molded on the outer circumferential surface of the toroidal core case, and the winding is made by passing a copper wire through the inner diameter of this cylindrical body. The number of turns is checked by checking whether the copper wire has penetrated the toroidal core case.The purpose of the cylindrical body provided on the outer surface of the toroidal core case is to protect the copper wire and ensure electrical insulation. That is.

A cylindrical body is integrally molded on the outer peripheral surface of a toroidal core case that houses a toroidal core, and the direction of the hollow part inside the cylindrical body is parallel to the circumferential surface of the case and the case axis direction, and the inner diameter of the cylindrical body The diameter of the hollow part is made slightly larger than the diameter of the copper wire to be wound, but the diameter is such that two copper wires cannot pass through it. The height of the cylindrical body shall be equal to or less than the thickness of the toroidal core case.
For winding, a copper wire is passed through one location of the cylindrical body once.
筒状体の数は、コイルの巻数に合わせて設け
る。巻数のチエツクは、筒状体に銅線が通つてい
るかどうかを確認し、通つていない筒状体がなけ
れば巻数は規定通りと判断出来る。 The number of cylindrical bodies is provided according to the number of turns of the coil. To check the number of turns, check whether the copper wire is passed through the cylindrical body, and if there is no cylindrical body that does not pass through, it can be determined that the number of turns is as specified.

A perforated cylindrical body 4 provided on the outer periphery of the toroidal core case 1 is made integrally with the case.

As described above, according to the present invention, the number of turns of the coil can be confirmed by checking whether or not the wound copper wire is inside the cylindrical body, instead of counting the number of turns, for example, from 1 to 80. In particular, when the number of turns of copper wire overlaps, if you count the number in the conventional manner, the copper wire may be hidden behind the copper wire and the number may be lost.
In the present invention, if the cylindrical bodies are formed so that they do not overlap, the number of turns can be easily checked.

る。 By using the insulating case of the present invention, electrical insulation can be ensured between the surrounding electronic components, etc. without the need for tape wrapping in the subsequent process, and the end of the coiled copper wire can be shaped into a cylindrical shape. Since it is fixed by the body, it has advantages such as a constant pin pattern.
