である。BACKGROUND ART As shown in FIG. 4, a conventional high-frequency coil A includes a bobbin 3 by providing a winding outer collar 2 intermittently protruding from a circumferential body 1 in the axial direction of the circumferential body, and an upper end portion of the circumferential body 1. The cylindrical body 4 is integrally connected to the cylindrical body 4, and with the cylindrical body 4 being chucked by a chuck device (not shown), winding wires are wound in each winding groove 5 and wiring is performed.After the work is completed, the cylindrical body 4 is cut off. Complete high frequency coil A. 6 is a high frequency magnetic core.
発明が解決しようとする問題点
上記のような構成ではつぎのような問題点があ

止めを行なわざるを得ず、その結果、最上部の
巻線溝５に巻装出来なくなつて、製品設計上の
制限をきたすという問題があつた。(1) In winding, wiring, etc., simply chucking the cylindrical body 4 will result in unstable chucking, and if the winding is wound in that state, the winding will be insufficient and the quality of the high frequency coil A will deteriorate. Therefore, the uppermost outer flange 2 must be chucked with a chuck device to position and prevent the bobbin 3 from rotating, and as a result, the winding groove 5 at the uppermost position cannot be wound. There was a problem with product design limitations.
(2) 筒体４の端部の肉厚が薄いため、チヤツキン
グにより、ボビン３の割れやヒビ発生のおそれ
があつた。(2) Since the wall thickness at the end of the cylindrical body 4 was thin, there was a risk that the bobbin 3 would break or crack due to chucking.
この発明の目的は、品質に優れ、製品設計上
の自由度も拡大でき、しかもボビンの欠損を防
止できる高周波コイルを提供することである。 It is an object of the present invention to provide a high-frequency coil that has excellent quality, can expand the degree of freedom in product design, and can prevent damage to the bobbin.
問題点を解決するための手段

る。Means for Solving the Problems The high-frequency coil of the present invention includes a bobbin in which winding grooves are formed between the outer flanges by providing winding outer flanges on the circumferential body intermittently projecting in the axial direction of the circumferential body, and a cylindrical shaft. The bobbin is configured to include a cylindrical body aligned with the center of the circumferential body of the bobbin and connected to one end of the circumferential body, and an outer chuck flange protruding from an end of the outer circumferential surface of the cylindrical body.

度も増すことになる。In this way, when the cylinder body with the outer flange for chuck protruding from the end of the outer peripheral surface is integrally formed with the center axis aligned with the bobbin, the bobbin is strengthened by chucking the bobbin with the cylindrical body and the outer flange. It is possible to secure the winding wire to each winding groove with high precision, and it is possible to provide products with excellent quality. In addition, since the cylindrical body and the outer flange serve as reinforcement for the bobbin, breakage of the bobbin can be prevented. Furthermore, it becomes possible to wind the winding wire also on the cylindrical part, which increases the degree of freedom in product design.

従来例と同様である。Embodiment An embodiment of the present invention will be described with reference to FIGS. 1 to 3. That is, this high frequency coil B
A chuck outer flange 7 is provided on the upper edge of the cylinder 4, and the high frequency magnetic core 6' is attached to the bobbin circumferential body 1.
The other structure is the same as that of the above-mentioned conventional example.

Since it is not necessary to check the outer collar 2 for winding, the winding 8 can be wound in all the winding grooves 5, and the degree of freedom in product setting can be expanded.
(2) 筒体４の端部が外鍔７により補強されるた
め、チヤツクによるボビン３の割れやヒビ発生
