出させた構造となっている。In general, a line filter takes the form of a bobbin 8 having a middle collar 7 that divides the winding, as shown in FIG. Lead out the end directly through the casing or terminal 11, insert the ■-shaped magnetic core 12 into the bobbin 8, combine it with the U-shaped magnetic core 13, and connect the ■-shaped magnetic core 12 and the U-shaped magnetic core 13 with the pressure contact member 14. This structure is assembled into a case 15 as shown in FIG. 6, and the terminal 11 is led out from the bottom plate 16.
なお、第７図はラインフィルターの構成回路を示す。Incidentally, FIG. 7 shows the configuration circuit of the line filter.

、シたがって、必要な高インダクタンスを得るにはコイ
ル９．１０の振数を多くしなければならない欠点がある
。According to the above-mentioned conventional line filter, the coils 9 and 10 are wound around the bobbin 8 in advance and then the magnetic cores 12 and 13 are combined, so the winding work is easy.
It is difficult to assemble them and requires a special joining member, and the magnetic core that creates the magnetic path is made by joining two components, so it is difficult to obtain one with high magnetic permeability. <
Therefore, there is a disadvantage that the frequency of the coils 9 and 10 must be increased in order to obtain the necessary high inductance.
本考案は上記従来の欠点を解消するものであり、以下そ
の詳細を一実施例を示す第１図〜第４図とともに説明す
る。The present invention solves the above-mentioned conventional drawbacks, and details thereof will be explained below with reference to FIGS. 1 to 4 showing one embodiment.
ボビン１は径方向線で分割された２つのボビン分割構成

。The bobbin 1 consists of two bobbin divided structures 1a and 1b divided along a radial line, and has flanges 2 and 2 at both ends and in the center.
．． 2, and as shown in FIG.
2. Driving teeth 3 are formed on the outer periphery of the collar at both ends, or at any one end as shown in FIG.
なお、第３図、第４図では両端のつば２に歯３を設ける
例を示したが、中央部のつば２の外周に歯３を設ける構
成とすることもできる。Although FIGS. 3 and 4 show an example in which the teeth 3 are provided on the flanges 2 at both ends, it is also possible to provide a configuration in which the teeth 3 are provided on the outer periphery of the flanges 2 at the center.
この２つのボビン分割構成体１ａ、１ｂを閉磁路磁心４
の一辺を囲んで接着等により結合させてボビン１を構成

装し、ラインフィルターを構成する。These two bobbin divided structures 1a and 1b are connected to a closed magnetic circuit magnetic core 4.
A bobbin 1 is constructed by surrounding one side of the coils and bonding them together by adhesive or the like, and a line filter is constructed by winding the primary and secondary coils 5 and 6 around the bobbin 1.
なむ、端子１１の導出およびケース１５への収納は前述
の従来のものと同様に構成する。The terminal 11 is led out and housed in the case 15 in the same manner as in the prior art described above.
上記本考案のラインフィルターは、ボビンが予め分割し
であるので閉磁路磁心と組み合せて透磁率の高い捲線が
でき、少ない振数で必要なインダクタンスが得られ、特
性のよいラインフィルターが得られる。In the line filter of the present invention, since the bobbin is pre-divided, it can be combined with a closed magnetic circuit magnetic core to form a winding with high magnetic permeability, the necessary inductance can be obtained with a small number of vibrations, and a line filter with good characteristics can be obtained.
しかも、ボビンのつばの外周に駆動用の歯を設けている
