本考案はインダクタンスとキヤパシタンスを組
合せたデイレイラインに関するもので、その主な
目的は伝送特性を改善し、合せて特性の均等化を
はかることにある。[Detailed Description of the Invention] The present invention relates to a delay line that combines inductance and capacitance, and its main purpose is to improve transmission characteristics and to equalize the characteristics.

た、コイルと一諸に巻き込んだアース巻線との間
のキヤパシタンスの値がまちまちで特性のばらつ
きがひどく、歩留りが悪いという欠点もある。 Since such a delay line generally has multiple sections of coils connected in series coaxially wound around the same bobbin, there is a problem in that the coupling between adjacent coils is too strong and the transmission characteristics deteriorate. Another disadvantage is that the capacitance between the coil and the ground winding wound around the coil varies, resulting in severe variations in characteristics and poor yield.

に接続されている。 In order to improve this problem, the present invention does not use the conventional method of winding the wire around the bobbin.
Precise inductance and capacitance are obtained by the coil and ground winding printed on both the front and back sides of the printed circuit board, thereby improving and making the transmission characteristics uniform. As illustrated in the drawing, the delay line of the present invention includes three or more coils L 1 connected in series,
Among L 2 , L 3 , ..., the odd number coil L 1 , L 3 ,
...is an even-numbered coil on the surface of printed circuit board 1.
L 2 , L 4 , ... are printed on the back side with the winding directions in the same direction, and each even-numbered coil L 2 ,
L 4 , . . . are arranged astride between the coils on the front surface, and the inner ends and outer ends of the respective coils on both the front and back surfaces are connected to each other by through holes 2. Then, earth windings C 1 , C 2 , C 3 . . . are printed in parallel to each coil on both the front and back sides.
The inner ends of each of these ground windings are open and the outer ends are connected to the ground baseline 3 printed on the side edge of the printed circuit board 1.
It is connected to the.
以上の如く、直列に連らなる各区間のコイルを
プリント基板の表裏両面に、交互に少しずつ中心
をずらせた状態に印刷すれば、隣接コイル間の結
合を適度に小さくすることができる。 As described above, by printing the coils of each section connected in series on both the front and back surfaces of the printed circuit board alternately with their centers slightly shifted, the coupling between adjacent coils can be appropriately reduced.
また、コイルの配置を適当にすれば、すなわ

合の方向を正負交互にして理想的な形にすること
ができる。 In addition, if the coils are arranged appropriately, that is, the center of the winding layer of the even-numbered coil on the back side, which is placed across the odd-numbered coils on the front side,
If the coils printed on both sides of the surface are placed inside the center, the coupling between the coils printed on the same surface will be negative, and the coupling between different surfaces will be positive.It is ideal to alternate the positive and negative directions of the coupling. It can be made into any shape.

善できる。 In this way, the coupling value and direction can be appropriately selected, which further improves the transmission characteristics. Also, since each coil and the parallel ground winding can be precisely printed, the inductance and capacitance values can be adjusted. It is easy to make it accurate and uniform, the characteristics are equalized, and the product yield can also be improved.
さらにコイルとアース巻線ならびにアース基線
とを同時にプリントできるためコスト的にも安価
になる。 Furthermore, since the coil, the ground winding, and the ground base line can be printed at the same time, the cost is also reduced.

Since the starting ends of the odd-numbered C 1 , C 3 , etc. are grounded, and the terminal ends of the even-numbered C 2 , C 4 ,... Deterioration can be prevented.
