Description

【考案の詳細な説明】 [産業上の利用分野] 本考案はラインフィルタに関し,特に,ディジタル機器間を接続する信号線から発生する輻射雑音を防止するラインフィルタに関する。 Description of invention] [Field of the Industrial present invention relates to a line filter, in particular, it relates to a line filter for preventing the radiation noise generated from a signal line connecting between digital devices.

[従来の技術] ディジタル機器間を接続する信号線より発生する輻射雑音を防止する手段の1つは,すべての信号線をフェライトコアに同相巻線を行なう方法が有効である。 One means for preventing radiation noise generated from the [prior art] signal line connecting between digital devices, the method of performing all of the phase windings a signal line on a ferrite core is effective.

従来例としては,第5図に示すように,コイルボビン6 As a conventional example, as shown in FIG. 5, the coil bobbin 6
に巻線5eを行ない,その後2個のU形状のフェライトコア4をコイルボビン6の上下から閉磁路を形成するように突き合わせ,この2個のコアを絶縁テープやコアホルダー(いずれも図示せず)で接合する構造である。 Performs the winding 5e, then butt two ferrite cores 4 of U-shaped from the top and bottom of the coil bobbin 6 so as to form a closed magnetic circuit, the two cores insulating tape or core holders (both not shown) in a structure of joining.

[考案が解決しようとする問題点] しかし,第5図に示すようにコイルボビン6に巻線5eを施した後に、U形状フェライトコア4,4をいちいち突き合せなければならず,コア同士の突き合せ作業に手間がかかるという問題点がある。 [Devise a problem to be solved point] However, after performing bobbin 6 wound around 5e as shown in FIG. 5, it must butt each time the U-shaped ferrite cores 4, 4, pick cores there is a problem in that time-consuming to fit work.

また,ラインフィルタを製造してしまうと,コアをいちいち分離しなければ巻線を追加することができず、そのため、特性の追加調整が困難であった。 Further, when the thus produced line filter, it is not possible to add a winding to be each time separated core, therefore, additional adjustments characteristics is difficult.

そこで,本考案の技術的課題は,コアの突き合せ作業を不要とし,特性の追加調整を可能としたラインフィルタを得ることにある。 Therefore, the technical problem of the present invention is to eliminate the need for butt work of the core is to obtain a possible and the line filter additional adjustment of properties.

[問題点を解決するための手段] 本考案のラインフィルタは,磁芯に複数の巻線を施してなるラインフィルタにおいて,上記磁芯は前記複数の巻線を通すための環状を呈すると共に、DIPモジュール型端子台に載せて成ることを特徴とするラインフィルタが得られる。 [Means for solving the problems] The present invention of the line filter, the line filter formed by applying a plurality of windings in core, together with the magnetic core exhibits an annular to pass the plurality of windings, line filter, characterized by comprising placing the DIP modular terminal block is obtained.

[実施例] 以下本考案の実施例を図面を用いて説明する。 Will be described with reference to EXAMPLES drawings the following examples the present invention.

第1図は本考案の一実施例を示す斜視図である。 Figure 1 is a perspective view showing an embodiment of the present invention.

本考案の一実施例のラインフィルタは長円形の環状のフェライトコア3に3本以上の信号線(図では4本)で同相の巻線5cをした本体をピン端子を備えた平板状のDIP Line filter of an embodiment of the present invention are tabular DIP having a pin terminal body in which the windings 5c of the same phase in the ferrite core 3 of oval annular three or more signal lines (four in the drawing)
モジュール形端子台1に縦置きにして載せて作られる。 It made put in the vertically to the module type terminal block 1.
縦置きとは、長円の環状のフェライトコアの外周面が端子台1に接するように置くことである。 Place a vertical, is to place as the outer peripheral surface of an annular ferrite core oblong is in contact with the terminal block 1. 巻線の端部のリード線は端子台1に備えたピン端子に接続する。 Lead end of the winding is connected to a pin terminal having a terminal block 1.

一方、第2図は本考案の第2の実施例を示す斜視図である。 On the other hand, FIG. 2 is a perspective view showing a second embodiment of the present invention. これは第1図に示したラインフィルタの長円形の環状のフェライトコア3に4本の信号線で同相の巻線5dをした本体を横置きにして端子台1に載せて作られる。 This is made by placing the terminal block 1 and transversely to the main body in which the windings 5d of the same phase in four signal lines in the ferrite core 3 of oval annular line filter shown in Figure 1. 横置きとはフェライトコア3の端面と端子台1とが接するように置くことである。 Horizontal and is to place in contact and the end face and the terminal block 1 of the ferrite core 3.

上述したように、これらの実施例では長円形の横断面形状を有している環状フェライトコアを用いることで端子台上にラインフィルタ本体を安定に設置し,又巻線を容易に行なえる。 As described above, these in the embodiment established a line filter body on the terminal block by using an annular ferrite core having an oval cross-sectional shape stable, easily the Matamaki line.

本考案のラインフィルタのその他の比較例としては,第3図や第4図に示すように,円筒状フェライトコア2に巻線5aまたは5bを施し,これをDIPモジュール型端子台1に載せ,巻線5aまたは5bの端部をDIPモジュール型端子台1に備えられた端子と接続して作られる。 Other comparative examples of the line filter of the present invention, as shown in FIG. 3 and FIG. 4, performs the cylindrical ferrite core 2 wound around 5a or 5b, put it to the DIP modular terminal blocks 1, the ends of the windings 5a or 5b are made in connection with a provided terminal DIP modular terminal blocks 1. この際環状フェライトコア2はDIPモジュール型端子台1の上に第3図に示すように環状コアの外周面と端子台が接する縦置きするのと第4図に示すように環状コアの端面と端子台が接する横置きにする。 In this case the annular ferrite core 2 and the end face of the annular core, as shown in FIG. 4 and to place the outer peripheral surface and the vertical terminal block contacts the annular core as shown in FIG. 3 on the DIP modular terminal block 1 to transversely terminal block contacts.

本考案の2つの実施例は、2つの比較例との相違、すなわち、長円形磁芯を搭載した構成により、高さ寸法を低くでき小形にできるという効果を期待できる。 Two embodiments of the present invention, the difference between the two comparative examples, i.e., the configuration equipped with the oblong core, can be expected an effect of the lower can compact the height.

[考案の効果] 以上のように本考案はDIPモジュール型端子台に突き合わせ不要な一体に形成された環状磁心(コア)を載せたことにより,環状磁心(コア)に巻線を通すことができるから,ラインフィルタの部品そのものを基板に取り付け後、巻線設計の変更が生じても、巻線を追加したりまたは巻線を削除したりして所望の特性を得ることができる。 The present invention as described above [Effect of invention] is by carrying the annular magnetic core formed unwanted integrally butt DIP modular terminal block (core) can be passed through the winding annular magnetic core (core) from after installing components themselves of the line filter on the substrate, even when changing the winding design can be or remove added or or winding the windings obtain desired characteristics.

また、巻線作業が容易となり,そして実装密度を上げることができ,環状磁心(コア)を安定して設置することができる。 Further, the winding work is facilitated, and mounting density can be increased, it is possible to install the annular magnetic core (core) stably.

尚,長円形磁芯を端子台の上に、任意に設置できるから高さ寸法を低くでき,スペースを取らないようにすることができる。 Incidentally, on the oval core of the terminal block, since it established arbitrarily can reduce the height dimension, it is possible not to take up space.
