本案は高周波用コイルボビンの構造に関するも
のである。[Detailed Description of the Invention] The present invention relates to the structure of a high frequency coil bobbin.
筒状体ボビンに線材を巻いた程度の簡単な構造

な不都合を生じる。すなわち、他の部品との接触
はコイルのＱや絶縁等の点で問題となる。 This type of coil, which has a simple structure such as a wire wound around a cylindrical bobbin, has conventionally been installed vertically on a printed circuit board. Since its support structure is based on lead wires, it rises and tilts during automatic soldering, causing problems such as coming into contact with other parts. That is, contact with other parts poses a problem in terms of the Q of the coil, insulation, etc.

る。 The present invention was proposed to solve such problems and to provide a coil bobbin that can be fixed on a printed circuit board even if the extending direction of the lead terminal is determined according to the number of turns of the coil.
本案の実施例について以下図面に従つて説明す
る。 Examples of the present invention will be described below with reference to the drawings.

も横ゆれを受けにくくなる。 Fig. 1 is a front view showing the state in which the coil bobbin according to the embodiment of the present invention is attached to a printed circuit board;
The figure is a side view thereof. Reference numerals 1 and 1' designate a collar portion of a cylindrical body made of synthetic resin, and a plurality of protrusions 2 to 5 and 2' to 5' are integrally formed on the outer periphery of the cylindrical body. When mounted on the printed circuit board 6, for example, the projections 3, 4, 3', 4' abut against the circuit board 6, thereby fixing the cylindrical body in place. 7 and 8 are lead terminals of the coil 11, which are inserted into the mounting holes of the printed circuit board and soldered 9 and 10 on the back side. Therefore, it is less susceptible to lateral vibration during automatic soldering.
又、コイルは、高周波用で周波数が高くなるに
従つて、巻数が少なくなり、ボビンに数回巻きさ
れることになる。その巻き数は周波数に応じて変
わり、誘導リアクタンスが変わる。そして、その
巻数は、例えば1/4回のステツプで変わる。この
為、ボビンに対するコイル１１のリード端子７，
８の延出する方向は全周方向において種々変わ
る。そこで、プリント基板６に取付ける場合、プ
リント基板６に当接する突片は、リード端子７，
８が延出している方向のものとなる。従つて、本
案のつば部１，１′によると、突片２〜５，２′〜
５′が全周に形成してあるから、リード端子７，
８が全周のどの方向へ延出してもそのリード端子
７，８の延出方向に応じた突片２〜５，２′〜
５′を基板６に当接することによつて筒状体を定
置させることができる。 Also, as the frequency of the coil increases for high frequency applications, the number of turns decreases, and the coil is wound around the bobbin several times. The number of turns changes according to the frequency, and the inductive reactance changes. The number of turns changes in steps of, for example, 1/4 turns. For this reason, the lead terminals 7, 11 of the coil 11 relative to the bobbin
Therefore, when the terminal is attached to the printed circuit board 6, the protruding pieces that come into contact with the printed circuit board 6 are arranged in a direction parallel to the lead terminals 7,
Therefore, according to the flange portion 1, 1' of the present invention, the protruding pieces 2-5, 2'-
Since the lead terminal 7,
No matter in which direction the lead terminals 7, 8 extend around the circumference, the protruding pieces 2-5, 2'-
The cylindrical body can be fixed in place by abutting the base plate 6 against the base plate 5'.

を多数直列に配列するようにしても同様である。 FIG. 3 is a perspective view of another embodiment of the present invention. In this case, radial protrusions 22, 23, 24, 2
2', 23' and 24' are protruding on three sides. The same effect can also be obtained by arranging a large number of protrusions in series between the ribs 1 and 1', for example between the protrusions 22 and 22'.
本案は以上のようにしてなるから、プリント基

７，８が筒状体の全周のいずれの方向へ延出して
も、その延出方向に対応した一対の突片を利用し
て、プリント板に筒状体を定置させることができ
る。 Since the present invention is constructed as described above, the mounting orientation will not be disturbed when assembling the coil on the printed circuit board. Since a plurality of protrusions are formed at predetermined intervals around the entire circumference of the cylindrical body, no matter which direction the lead terminals 7 and 8 of the coil extend around the cylindrical body, The cylindrical body can be fixed on the printed board by using a pair of protrusions corresponding to the extending direction.
なお、コイルが巻かれたコイルボビンの外周を
薄くモールド仕上げしても同様な効果が得られ
る。 Note that the same effect can be obtained by thinly molding the outer periphery of the coil bobbin around which the coil is wound.
