Description

この発明は、信号線をコモンモードチョークコイルやコモンモードノイズフィルタ等の巻線型コイルのコアに巻回する巻線型コイルの巻線方法に関するものである。   The present invention relates to a winding method of a winding coil in which a signal line is wound around a core of a winding coil such as a common mode choke coil or a common mode noise filter.

コモンモードチョークコイルやコモンモードノイズフィルタ等の巻線型コイルは、ＤＶＩ（Digital Visual Interface），ＨＤＭＩ（High Definition Multimedia Interface）やＩＥＥＥ（Institute of Electrical and Electronic Engineers）１３９４等の規格の高速差動伝送路に用いられることが多い。このような高速差動伝送路においては、高速差動信号に影響を与えることなくコモンモードノイズを除去する特性が、当該巻線型コイルに要求される。
高速差動信号に影響を与えることなく即ち高速差動信号を減衰させることなく、高速差動信号をコイル内通過させるには、巻線型コイルの特性インピーダンスを伝送線路や接続回路のインピーダンスに整合させて、反射による定在波の発生を防止する必要がある。 Wire-wound coils such as common mode choke coils and common mode noise filters are high-speed differential transmission lines such as DVI (Digital Visual Interface), HDMI (High Definition Multimedia Interface) and IEEE (Institute of Electrical and Electronic Engineers) 1394. It is often used for. In such a high-speed differential transmission line, the winding type coil is required to have a characteristic of removing common mode noise without affecting the high-speed differential signal.
To pass the high-speed differential signal through the coil without affecting the high-speed differential signal, that is, without attenuating the high-speed differential signal, match the characteristic impedance of the wound coil to the impedance of the transmission line or connection circuit. Therefore, it is necessary to prevent the occurrence of standing waves due to reflection.

ところで、コモンモードチョークコイルやコモンモードノイズフィルタ等の巻線型コイルは、図１５に示すように、高速差動信号であるD＋信号を通す第１信号線１とD−信号を通す第２信号線２とをコア３の巻芯３０に巻き付けると共に、第１及び第２信号線１，２の端部をコア３の両端の鍔部３１に設けられた電極３１ａ，３１ｂに接続した構造になっている。この巻線型コイルの特性インピーダンスは、第１及び第２信号線１，２の線路及び磁芯である巻芯３０によるディファレンシャルモードインダクタンスと第１及び第２信号線１，２の間に生じる区間容量によって決定される。したがって、所望の適正な区間容量を得るためには、図に示すように、第１及び第２信号線１，２の間の距離ｄが全てのターンで等しくなければならない。しかし、実際には、第１及び第２信号線１，２の巻回時にずれが生じて、図１６に示すように、第１及び第２信号線１，２の間の距離ｄにばらつきが発生することが多い。 Incidentally, wire-wound coil such as common mode choke coil and common mode noise filter, as shown in FIG. 15, the first signal line 1 and D through the D + signal is a high-speed differential signal - second signal through a signal The wire 2 is wound around the core 30 of the core 3 and the ends of the first and second signal wires 1 and 2 are connected to the electrodes 31 a and 31 b provided on the flanges 31 at both ends of the core 3. ing. The characteristic impedance of the winding coil is that the section capacitance generated between the differential mode inductance of the first and second signal lines 1 and 2 and the differential core inductance 30 formed by the magnetic core 30 and the first and second signal lines 1 and 2. Determined by. Therefore, in order to obtain a desired appropriate section capacity, as shown in the figure, the distance d between the first and second signal lines 1 and 2 must be equal in all turns. However, in actuality, a deviation occurs when the first and second signal lines 1 and 2 are wound, and the distance d between the first and second signal lines 1 and 2 varies as shown in FIG. Often occurs.

そこで、図１７に示すように、ダミー線１２（図において黒塗りの線材）の両側に第１及び第２信号線１，２を接触させた状態で、第１及び第２信号線１，２とダミー線１２とを同時に巻き付けることにより、第１及び第２信号線１，２の間の距離ｄを全てのターンで等しくすることができる技術が提案されている（例えば、特許文献１参照）。   Therefore, as shown in FIG. 17, the first and second signal lines 1 and 2 are in contact with the first and second signal lines 1 and 2 on both sides of the dummy line 12 (black wire in the figure). And a dummy wire 12 are simultaneously wound so that the distance d between the first and second signal lines 1 and 2 can be made equal in all turns (for example, see Patent Document 1). .

しかし、図１７に示した従来の技術では、次のような問題がある。
図１７に示すように、第１及び第２信号線１，２の端部１ａ，２ａを、鍔部３１の平坦な下面に形成された電極３１ａ，３１ｂに接続する場合には、ダミー線１２の端部１２ａを、電極３１ａ，３１ｂとほぼ面一の領域に接続する。したがって、ダミー線１２の端部１２ａを第１及び第２信号線１，２の端部１ａ，２ａのいずれかよりも高く盛り上がった状態に接続した場合には、図１８に示すように、鍔部３１がシーソー状態になり、基板１００への実装時に電極３１ａ，３１ｂの一方が浮いてしまい、導通不良を起こすことがある。 However, the conventional technique shown in FIG. 17 has the following problems.
As shown in FIG. 17, when connecting the end portions 1 a and 2 a of the first and second signal lines 1 and 2 to the electrodes 31 a and 31 b formed on the flat lower surface of the flange portion 31, the dummy line 12 is used. Is connected to a region substantially flush with the electrodes 31a and 31b. Therefore, when the end portion 12a of the dummy line 12 is connected to a state where it rises higher than either of the end portions 1a and 2a of the first and second signal lines 1 and 2, as shown in FIG. The part 31 is in a seesaw state, and one of the electrodes 31a and 31b may float when mounted on the substrate 100, resulting in poor conduction.

また、巻線型コイルの中には、図１９（ａ）に示すように、鍔部３１の下面が平坦でなく、ギャップＧが電極３１ａ，３１ｂの間に凹設されたものがある。このような巻線型コイルに、ダミー線１２を巻回した場合には、ダミー線１２の端部１２ａを鍔部３１に接続することができないので、その端部１２ａをギャップＧに納めた状態にすることが多い。
しかし、かかる状態では、図１９（ｂ）に示すように、ダミー線１２の端部１２ａが、ギャップＧから延び出て鍔部３１の下方に突出し、一方の鍔部３１を基板１００から浮せて導通不良を起こさせることがある。 In addition, in some wound coils, as shown in FIG. 19A, the bottom surface of the flange portion 31 is not flat and the gap G is recessed between the electrodes 31a and 31b. When the dummy wire 12 is wound around such a wound coil, the end portion 12a of the dummy wire 12 cannot be connected to the flange portion 31, so that the end portion 12a is placed in the gap G. Often to do.
However, in this state, as shown in FIG. 19B, the end 12 a of the dummy line 12 extends from the gap G and protrudes below the flange 31, and the one flange 31 is lifted from the substrate 100. May cause poor conduction.

以上詳しく説明したように、この発明の巻線型コイルの巻線方法によれば、線材巻付過程において、各第１ダミー線の両隣に並ぶ信号線が各第１ダミー線の両側に接するように、Ｍ本の信号線とＭ−１本の信号線とがコアの巻芯に巻き付けられるので、Ｍ本の信号線の間隔の全てが第１ダミー線の径に維持される。これにより、信号線間の区間容量が適正な一定値を有し、巻線型コイルの特性インピーダンスが適正値に保たれる。この結果、巻線型コイルの特性インピーダンスを伝送線路や接続回路のインピーダンスに整合させることができ、反射による定在波の発生を防止して、高速差動信号の減衰を防止することができる。しかも、線材除去過程において、第１ダミー線をコアから除去するので、巻線型コイルの基板等への実装時に、図１８や図１９に示したように、第１ダミー線が巻線型コイルの電極の一方を浮かせたり、一方の鍔部を基板等から浮せたして、導通不良を起こさせるという事態の発生を完全に防止することができるという優れた効果がある。   As described above in detail, according to the winding method of the winding type coil of the present invention, in the wire winding process, the signal lines arranged on both sides of each first dummy line are in contact with both sides of each first dummy line. Since the M signal lines and the M−1 signal lines are wound around the core of the core, all the intervals of the M signal lines are maintained at the diameter of the first dummy line. Thereby, the section capacitance between the signal lines has an appropriate constant value, and the characteristic impedance of the wound coil is kept at an appropriate value. As a result, the characteristic impedance of the wound coil can be matched with the impedance of the transmission line or the connection circuit, and the occurrence of a standing wave due to reflection can be prevented, thereby preventing the high-speed differential signal from being attenuated. In addition, since the first dummy wire is removed from the core in the wire material removal process, the first dummy wire is an electrode of the winding coil as shown in FIGS. 18 and 19 when the winding coil is mounted on a substrate or the like. There is an excellent effect that it is possible to completely prevent a situation in which one of the above is floated or one of the collars is floated from the substrate or the like to cause a conduction failure.

特に、請求項２の発明によれば、第２ダミー線を、信号線と第１ダミー線とがコアの巻芯に巻き付けられた際に生じる間隙に位置し且つ両隣の信号線と接するように、巻芯に巻付けた後、第１ダミー線と第２ダミー線とをコアから除去する構成であるので、コアの巻芯に巻き付けられているＭ本の信号線を束とする束間の間隙も一定にすることができ、この結果、巻線型コイルの特性インピーダンスをさらに高精度で設定することができるという効果がある。   In particular, according to the invention of claim 2, the second dummy line is positioned in a gap generated when the signal line and the first dummy line are wound around the core of the core and is in contact with the adjacent signal lines. Since the first dummy wire and the second dummy wire are removed from the core after being wound around the core, between the bundles of M signal lines wound around the core core The gap can also be made constant. As a result, there is an effect that the characteristic impedance of the wound coil can be set with higher accuracy.

In order to facilitate understanding, in these drawings, the first and second signal lines 1 and 2 are indicated by solid lines, and the first dummy line 12 is indicated by broken lines.

線材位置決め過程Ｓ１は、第１及び第２信号線と第１ダミー線とをコア３の上に配置する過程である。
具体的には、図５（ａ）に示すように、第１信号線１，第１ダミー線１２，第２信号線２の順で交互に並べられ且つ線材保持器１２０のノズル１２１，１２２，１２３から繰り出された第１信号線１，第１ダミー線１２及び第２信号線２を、線チャック１１０に把持させた後、線材保持器１２０を３次元方向に移動させることによって、第１信号線１，第１ダミー線１２及び第２信号線２を、ガイドピン１１１，１１２，１１３に引っ掛けてから、巻治具１０１に把持されたコア３まで導く。
続いて、図５（ｂ）に示すように、第１信号線１，第１ダミー線１２及び第２信号線２をコア３の鍔部３１に係合させるようにして、第１及び第２信号線１，２を電極３１ａ，３１ｂ上に位置させると共に、第１ダミー線１２を電極３１ａ，３１ｂの間に位置させる。そして、線材保持器１２０を、矢印で示すように回転させて、ノズル１２１，１２２，１２３がコア３の中心軸Ｌの方向にちょうど第１信号線１，第１ダミー線１２及び第２信号線２の径の幅だけずれた配置となるようにする。これにより、第１信号線１，第１ダミー線１２及び第２信号線２が、コア３の鍔部３１に係合した状態でコア３の中心軸Ｌに交差するように、配置される。 The wire positioning process S1 is a process of arranging the first and second signal lines and the first dummy line on the core 3.
Specifically, as shown in FIG. 5A, the first signal lines 1, the first dummy lines 12, and the second signal lines 2 are alternately arranged in this order, and the nozzles 121, 122, After the first signal line 1, the first dummy line 12 and the second signal line 2 drawn out from 123 are gripped by the line chuck 110, the wire holder 120 is moved in the three-dimensional direction to thereby generate the first signal. The wire 1, the first dummy wire 12, and the second signal wire 2 are hooked on the guide pins 111, 112, 113 and then guided to the core 3 held by the winding jig 101.
Subsequently, as shown in FIG. 5B, the first signal line 1, the first dummy line 12, and the second signal line 2 are engaged with the flange portion 31 of the core 3, so that the first and second signal lines are engaged. The signal lines 1 and 2 are positioned on the electrodes 31a and 31b, and the first dummy line 12 is positioned between the electrodes 31a and 31b. Then, the wire rod holder 120 is rotated as indicated by an arrow so that the nozzles 121, 122, and 123 are exactly in the direction of the central axis L of the core 3, the first signal line 1, the first dummy line 12, and the second signal line. The arrangement is shifted by the width of the diameter of 2. Accordingly, the first signal line 1, the first dummy line 12, and the second signal line 2 are arranged so as to intersect the central axis L of the core 3 while being engaged with the flange portion 31 of the core 3.

かかる状態から、線材巻付過程Ｓ２を実行する。
線材巻付過程Ｓ２は、コア３の巻芯３０に巻付ける過程である。
具体的には、図６（ａ）に示すように、コア３を巻治具１０１と共に矢印方向に回転させ、第１信号線１，第１ダミー線１２及び第２信号線２をコア３の巻芯３０部分に同時に並列に巻き付けて行く。この際、線材保持器１２０は、巻線の進行に伴い、コア３の中心軸Ｌ方向（図の下方向）に移動させる。このように線材保持器１２０をコア３に対して所定の角度で傾かせた状態で巻線することにより、第１信号線１，第１ダミー線１２及び第２信号線２が巻芯３０に整列状態で隙間なく巻線される。すなわち、各第１ダミー線１２の両隣に並ぶ第１及び第２信号線１，２が各第１ダミー線１２の両側に接した状態で、第１信号線１，第１ダミー線１２及び第２信号線２が巻芯３０に巻き付けられる。
そして、図６（ｂ）に示すように、巻線がコア３の鍔部３１の手前まで進行したら、巻治具１０１の回転を終えると共に、線材保持器１２０を移動させて、第１信号線１，第１ダミー線１２及び第２信号線２を鍔部３１に係合させる。さらに、線材保持器１２０を回転させながら移動することにより、第１信号線１，第１ダミー線１２及び第２信号線２をアーム１３０のガイドピン１４１，１４２，１４３に引っ掛ける。この際、第１及び第２信号線１，２が鍔部３１の電極３１ａ，３１ｂに重なるようにすると共に、第１ダミー線１２が電極３１ａ，３１ｂの間に位置するようにする。
しかる後、図６（ｃ）に示すように、第１信号線１，第１ダミー線１２及び第２信号線２を、ガイドピン１４１，１４２，１４３の後段側に位置した線チャック１４０で把持する。 From this state, the wire winding process S2 is executed.
The wire winding process S <b> 2 is a process of winding around the core 30 of the core 3.
Specifically, as shown in FIG. 6A, the core 3 is rotated in the direction of the arrow together with the winding jig 101, and the first signal line 1, the first dummy line 12, and the second signal line 2 are connected to the core 3. Wind around the core 30 in parallel at the same time. At this time, the wire retainer 120 is moved in the direction of the central axis L of the core 3 (downward in the drawing) as the winding progresses. Thus, by winding the wire retainer 120 in a state inclined at a predetermined angle with respect to the core 3, the first signal line 1, the first dummy line 12, and the second signal line 2 are connected to the core 30. It is wound without gaps in the aligned state. That is, the first signal line 1, the first dummy line 12, and the first signal line 1 are arranged in a state where the first and second signal lines 1, 2 arranged on both sides of each first dummy line 12 are in contact with both sides of each first dummy line 12. Two signal lines 2 are wound around the core 30.
Then, as shown in FIG. 6B, when the winding has proceeded to the front side of the flange portion 31 of the core 3, the rotation of the winding jig 101 is finished and the wire rod holder 120 is moved to move the first signal line. The first dummy line 12 and the second signal line 2 are engaged with the flange 31. Further, the first signal line 1, the first dummy line 12, and the second signal line 2 are hooked on the guide pins 141, 142, and 143 of the arm 130 by moving the wire holder 120 while rotating it. At this time, the first and second signal lines 1 and 2 are overlapped with the electrodes 31a and 31b of the flange 31, and the first dummy line 12 is positioned between the electrodes 31a and 31b.
Thereafter, as shown in FIG. 6C, the first signal line 1, the first dummy line 12, and the second signal line 2 are gripped by the line chuck 140 located on the rear side of the guide pins 141, 142, and 143. To do.

かかる状態で、ダミー線除去過程Ｓ３を実行する。
ダミー線除去過程Ｓ３は、第１ダミー線１２をコア３から除去する過程である。
具体的には、まず、図７（ａ）に示すように、コア３に巻き付けられた第１及び第２信号線１，２の両端部を切断して切断端部を固定する。
図８は、第１及び第２信号線１，２の固定状態を示す平面図である。
図８に示すように、第１及び第２信号線１，２の切断端部１ａ，２ａは、鍔部３１の電極３１ａ，３１ｂにそれぞれ熱圧着等の工法により溶着されることで、固定される。 In this state, the dummy line removal process S3 is executed.
The dummy line removal process S3 is a process of removing the first dummy line 12 from the core 3.
Specifically, first, as shown in FIG. 7A, both ends of the first and second signal lines 1 and 2 wound around the core 3 are cut to fix the cut ends.
FIG. 8 is a plan view showing a fixed state of the first and second signal lines 1 and 2.
As shown in FIG. 8, the cut ends 1a and 2a of the first and second signal lines 1 and 2 are fixed by being welded to the electrodes 31a and 31b of the flange 31 by a method such as thermocompression bonding, respectively. The

しかる後、第１ダミー線１２を線材保持器１２０で保持した状態で巻き戻す。すなわち、図７（ｂ）に示すように、コア３を巻治具１０１と共に矢印方向に逆回転させて、第１ダミー線１２をコア３の巻芯３０から解いていく。この際、線材保持器１２０は、巻き戻しの進行に伴い、コア３の中心軸Ｌ方向（図の上方向）に逆移動させる。
図９は、第１ダミー線１２の巻き戻し状態を示す断面図である。
図９の二点鎖線で示すように、第１ダミー線１２が巻芯３０に巻き付けられているときには、第１ダミー線１２が両隣の第１及び第２信号線１，２に接している。このため、第１ダミー線１２と第１及び第２信号線１，２との間の摩擦力が大きいと、実線で示すように、第１ダミー線１２を解く際に、その摩擦力によって、第１及び第２信号線１，２の間隙が広がるおそれがある。しかし、この実施例では、第１及び第２信号線１，２２の滑性皮膜２２を、第１ダミー線１２に対して滑り性を有する素材で形成したので、第１ダミー線１２を解く際に、第１及び第２信号線１，２に対する摩擦力はほとんど生じない。この結果、第１及び第２信号線１，２間の距離ｄは、第１ダミー線１２を解いた後も維持されることとなる。 Thereafter, the first dummy wire 12 is rewound while being held by the wire rod holder 120. That is, as shown in FIG. 7B, the core 3 is reversely rotated in the direction of the arrow together with the winding jig 101, and the first dummy wire 12 is unwound from the core 30 of the core 3. At this time, the wire rod holder 120 is moved backward in the direction of the central axis L of the core 3 (upward in the drawing) as the rewinding proceeds.
FIG. 9 is a cross-sectional view showing the unwinding state of the first dummy wire 12.
As shown by a two-dot chain line in FIG. 9, when the first dummy line 12 is wound around the core 30, the first dummy line 12 is in contact with the adjacent first and second signal lines 1 and 2. For this reason, when the frictional force between the first dummy line 12 and the first and second signal lines 1 and 2 is large, as shown by the solid line, when the first dummy line 12 is unwound, the frictional force There is a possibility that the gap between the first and second signal lines 1 and 2 may be widened. However, in this embodiment, the slipping film 22 of the first and second signal lines 1 and 22 is formed of a material having slipperiness with respect to the first dummy line 12, so that the first dummy line 12 is unraveled. In addition, the frictional force with respect to the first and second signal lines 1 and 2 hardly occurs. As a result, the distance d between the first and second signal lines 1 and 2 is maintained even after the first dummy line 12 is unwound.

そして、線材保持器１２０による第１ダミー線１２の巻き戻しが完全に終わると、図７（ｃ）に示すように、第１ダミー線１２をコア３から取り外すことができ、コア３には、第１及び第２信号線１，２のみが装着されている。
図１０は、ダミー線除去過程Ｓ３実行後に得た巻線型コイルの平面図である。
ダミー線除去過程Ｓ３の実行によって得た巻線型コイルは、第１及び第２信号線１，２がコア３の巻芯３０に巻き付けられ、第１及び第２信号線１，２の端部１ａ，２ａが鍔部３１の電極３１ａ，３１ｂに溶着された構造になっている。しかも、線径ｄの第１ダミー線１２を取り除いたので、第１及び第２信号線１，２の間の距離が全て均一に「ｄ」であり、ばらつきは生じない。これにより、第１及び第２信号線１，２間の区間容量が適正な一定値を有し、巻線型コイルの特性インピーダンスが適正値に保たれる。
また、ダミー線除去過程Ｓ３において、第１ダミー線１２をコア３から除去したので、巻線型コイルの基板等への実装時に、図１８や図１９に示したように、第１ダミー線が巻線型コイルの電極の一方を浮かせたり、一方の鍔部を基板等から浮せたして、導通不良を起こさせるという事態は生じない。 Then, when the unwinding of the first dummy wire 12 by the wire retainer 120 is completed, the first dummy wire 12 can be removed from the core 3 as shown in FIG. Only the first and second signal lines 1 and 2 are attached.
FIG. 10 is a plan view of the wound coil obtained after the dummy line removal step S3.
In the wound coil obtained by executing the dummy wire removal step S3, the first and second signal lines 1 and 2 are wound around the core 30 of the core 3, and the end portions 1a of the first and second signal lines 1 and 2 are wound. , 2a are welded to the electrodes 31a, 31b of the flange 31. In addition, since the first dummy line 12 having the wire diameter d is removed, the distance between the first and second signal lines 1 and 2 is all uniformly “d”, and no variation occurs. Thereby, the section capacitance between the first and second signal lines 1 and 2 has an appropriate constant value, and the characteristic impedance of the winding coil is kept at an appropriate value.
Further, since the first dummy line 12 is removed from the core 3 in the dummy line removing step S3, the first dummy line is wound when the winding type coil is mounted on the substrate or the like as shown in FIGS. It does not occur that one of the electrodes of the linear coil is floated or one of the collars is lifted from the substrate or the like to cause poor conduction.

This embodiment is different from the first embodiment in the dummy line removal step S3.
That is, in the first embodiment, the first dummy line 12 is removed by rewinding, but in this embodiment, the first dummy line 12 is removed by being removed.

具体的には、線材巻付過程Ｓ２を実行した後、図１１（ａ）に示すように、コア３に巻き付けられた第１及び第２信号線１，２の両端部を切断して第１及び第２信号線１，２の切断端部１ａ，２ａを、鍔部３１の電極３１ａ，３１ｂにそれぞれ溶着する。また、第１ダミー線１２においても、第１ダミー線１２の一方端部１２ａを切断してこの切断端部１２ａを解放する。
しかる後、図１１（ｂ）に示すように、コア３を巻治具１０１で固定し、コア３を動かさない状態にして、線材保持器１２０により第１ダミー線１２の他方端部１２ｂを引っ張る。これにより、図１１（ｃ）に示すように、第１ダミー線１２をコア３からスムーズに抜き取ることができる。
この実施例の方法は、第１及び第２信号線１，２の巻数が少ない巻線型コイルにおいて特に有効である。

The cut ends 1 a and 2 a of the second signal lines 1 and 2 are welded to the electrodes 31 a and 31 b of the flange 31, respectively. Also, in the first dummy line 12, one end 12a of the first dummy line 12 is cut to release the cut end 12a.
After that, as shown in FIG. 11B, the core 3 is fixed by the winding jig 101, the core 3 is not moved, and the other end portion 12b of the first dummy wire 12 is pulled by the wire rod holder 120. .

In this example, a water-soluble fiber mainly composed of polyvinyl alcohol was used as the first dummy wire 12.
In the dummy line removing step S3, as shown in FIG. 12, not only both ends of the first and second signal lines 1 and 2 but also both ends of the first dummy line 12 are cut. At this time, the cut ends 1a and 2a of the first and second signal lines 1 and 2 are welded to the electrodes 31a and 31b of the flange 31, respectively, and both ends 12a and 12a of the first dummy line 12 are in a released state.

次に、この発明の第５実施例について説明する。
図１４は、この発明の第５実施例に係る巻線型コイルの巻線方法を説明するための概略断面図である。
上記実施例では、線材巻付過程Ｓ２において、図１４（ａ）に示すように、第１及び第２信号線１，２を第１ダミー線１２に接した状態で巻付けるので、ダミー線除去過程Ｓ３の実行によって、均一な第１及び第２信号線１，２間距離ｄを得ることができる。しかしながら、第１及び第２信号線１，２と第１ダミー線１２とを束とする束間に間隙Ｄを生じさせる場合には、線材巻付過程Ｓ２の実行時に、全ての間隙Ｄが等しくならず、ばらつきが生じるおそれがある。

その他の構成、作用および効果は、上記第１ないし第４実施例と同様であるので、その記載は省略する。 Next explained is the fifth embodiment of the invention.
FIG. 14 is a schematic cross-sectional view for explaining the winding method of the wound coil according to the fifth embodiment of the present invention.
In the above embodiment, in the wire winding process S2, as shown in FIG. 14A, the first and second signal lines 1 and 2 are wound in contact with the first dummy line 12, so that the dummy line is removed. By performing step S3, a uniform distance d between the first and second signal lines 1 and 2 can be obtained. However, when the gap D is generated between the bundles of the first and second signal lines 1 and 2 and the first dummy line 12, all the gaps D are equal when the wire winding process S2 is performed. In other words, there is a risk of variations.
Therefore, in this embodiment, as shown in FIG. 14B, the first and second signal lines 1 and 2 and the first dummy line 12 are wound around the core 30 of the core 3 in the wire winding step S2. The second dummy wire 13 is wound around the core 30 so as to be in the gap D generated at the time of contact and in contact with the adjacent first and second signal lines 1 and 2. Then, in the dummy line removing step S3, the first dummy line 12 and the second dummy line 13 are removed from the core 3, thereby making the first and second signal lines 1, 2 as shown in FIG. Not only the distance d between, but also the gaps D between the bundles are all equal, and as a result, a more accurate characteristic impedance can be obtained.
Other configurations, operations, and effects are the same as those in the first to fourth embodiments, and thus description thereof is omitted.
