生し、シールドケース６と接触ショートする。(Structure of conventional example and its problems) Conventionally, this type of high-frequency coil has a structure as shown in FIG. In the figure, a tip 2 is embedded and fixed in a terminal plate 1, and a coil 4 starts to be wound around this terminal.
At the end of winding, the lead wire is wired. In this case, since the terminal embedded in the terminal board is round, the lead wire may slip, loosen, or come undone when the winding start lead wire is wound around the terminal. Therefore, the number of windings increases, and there is a risk that the wiring will protrude from the back side of the terminal board and break. Furthermore, when cutting the extra wire, the lead wire is torn off due to surface contact with the tip, which causes whiskers on the lead wire and causes contact with the shield case 6 and a short circuit.
また刃物で余線を切断する場合、リード巻付部より約１
ｍの間隔をあけなければ、巻付部まで切断する危険性が
ある。Also, when cutting the extra wire with a knife, approximately 1 inch from the lead wrapping part.
If you do not leave a gap of m, there is a risk that the wrapped portion will be cut.
（発明の目的）
本発明の目的は、従来例の欠点を解消し、コイルのリー
ド線が巻き易すく、リード線がゆるんだリ、はどけたり

。(Object of the Invention) The object of the present invention is to eliminate the drawbacks of the conventional example, to make it easy to wind the lead wire of the coil, to eliminate the risk of the lead wire coming loose or coming loose, and to prevent short-circuiting due to contact with the shield case. It is an object of the present invention to provide a high frequency coil that avoids this problem.

本発明の高周波コイルは、端子板に埋設して固定されて
いる端子に、少なくとも１箇所以上のエッチ部をもうけ
た端子、すなわち負端子、または三角端子等を使用する
ものである。(Structure of the Invention) The high-frequency coil of the present invention uses a terminal that is embedded and fixed in a terminal board and has at least one etched portion, that is, a negative terminal, a triangular terminal, etc. be.
また年端子を７字、Ｌ字、Ｕ字等の形状に加工した端子
を端子板に埋設して固定したものである。In addition, terminals processed into shapes such as 7-characters, L-shapes, and U-shapes are embedded in the terminal board and fixed.
（実施例の説明） 本発明の一実施例を第２図に基づいて説明する。(Explanation of Examples) An embodiment of the present invention will be described based on FIG. 2.
同図において、端子板にエッチ部（カド）２を具えた負

２ａに巻き付け、ドラムコアー３の外周には高周波コイ
ルを巻き、キャップコアー５をかぶせて、シールドケー
ス６に収納されている。In the figure, a negative terminal 2a having an etched portion (edge) 2 is embedded and fixed in the terminal plate. A drum core 3 is adhesively fixed to a terminal plate, a lead wire 4a of a coil 4 is wound around a negative terminal 2a, a high frequency coil is wound around the outer periphery of the drum core 3, a cap core 5 is covered, and the drum core 3 is housed in a shield case 6.
上記構成による端子板に埋設している端子形状は、実施
例では負端子２ａであるが、三角２ｂを使用してもよい
。また年端子を７字２ｃ、 Ｌ字２ｄ、 Ｕ字２ｅのよ
うに加工した端子を使用してもよい。The shape of the terminal buried in the terminal board having the above configuration is the negative terminal 2a in the embodiment, but a triangular shape 2b may also be used. You may also use terminals that have been modified to have a 7-character 2c, an L-shape 2d, or a U-shape 2e.
（発明の効果）
本発明によれば、端子にエッチ部（カド）Ｚをも□うけ

エツジ部をテコにして無理なく切断できるため、作業性
も向上する効果がある。(Effects of the Invention) According to the present invention, by providing the terminal with an etched portion (edge) Z, the lead wire makes point contact at the edge portion to prevent it from slipping and becoming loose or coming off. This can be prevented. In addition, the number of times the lead wire is wound around the terminal is reduced, making it possible to make the device smaller and thinner. In addition, gold wire can be cut easily using the edge portion as leverage, which has the effect of improving work efficiency.
