Description

本発明は、回路基板に組込まれるチョークコイル台座および当該チョークコイル台座が組込まれた回路基板を備える空気調和機のコントローラに関する。   The present invention relates to a choke coil base incorporated in a circuit board and an air conditioner controller including a circuit board in which the choke coil base is incorporated.

チョークコイルを回路基板に実装する際には、実装を容易にし、かつ該チョークコイルと基板の回路配線との絶縁距離を確保するために、通常は、該チョークコイルをチョークコイル台座に載置して実装する。   When mounting a choke coil on a circuit board, the choke coil is usually placed on a choke coil base in order to facilitate mounting and secure an insulation distance between the choke coil and circuit wiring on the board. And implement.

従来のチョークコイル台座は、載置される特定のチョークコイルのサイズ、形状、巻線の巻回数等に合わせて、該チョークコイル毎に用意されていた。   Conventional choke coil pedestals have been prepared for each choke coil in accordance with the size and shape of a specific choke coil to be placed, the number of winding turns, and the like.

例えば、特許文献1に開示されている台座付トロイダルコイル用コアケースの台座には、トロイダルコアケースと係合させるための係止爪を有する台座突起部と、巻線端部に半田付けされたリード線位置に合わせて形成され該リード線を通すための挿入穴と、が設けられている。   For example, the pedestal of the core case for toroidal coils with a pedestal disclosed in Patent Document 1 is soldered to a pedestal protrusion having a locking claw for engaging with the toroidal core case and a winding end. An insertion hole formed in accordance with the lead wire position and through which the lead wire passes is provided.

また、例えば、特許文献2に開示されている台座付コイルの台座は、コアケースの嵌合部に結合させるための保持部が突設され、巻線の端子の位置決めを容易にするために、貫通孔に代えて台座の端部で開口する貫通溝が設けられている。   In addition, for example, in the pedestal of the coil with pedestal disclosed in Patent Document 2, a holding part for coupling to the fitting part of the core case is provided so as to facilitate positioning of the terminal of the winding. Instead of the through hole, a through groove opened at the end of the pedestal is provided.

特開平7−45444号公報Japanese Patent Laid-Open No. 7-45444 特開2003−272924号公報JP 2003-272924 A

このように、特許文献1および2に示すような従来のチョークコイル台座は、個々のチョークコイルに合わせて製作するため、コスト高とならざるを得なかった。   As described above, the conventional choke coil pedestal as shown in Patent Documents 1 and 2 is manufactured in accordance with individual choke coils, and thus has to be expensive.

さらに、従来のチョークコイル台座は、絶縁距離が確保できないので、端子の位置決めを容易にするために開口部の面積を増やすことが困難であるという問題点もあった。   Furthermore, since the conventional choke coil base cannot secure an insulation distance, there is a problem that it is difficult to increase the area of the opening to facilitate positioning of the terminals.

本発明は、このような従来の問題点に鑑みてなされたものであり、絶縁距離の確保と巻線の位置決めを容易にすることとを両立し、かつ複数のチョークコイルに対応するチョークコイル台座を提供することを目的とする。   The present invention has been made in view of such conventional problems, and provides a choke coil pedestal that is compatible with securing of an insulation distance and facilitating positioning of a winding and corresponding to a plurality of choke coils. The purpose is to provide.

本発明の請求項1に係るチョークコイル台座は、回路基板に組込まれるチョークコイル台座であって、片面にチョークコイルが載置される板状の台座本体と、前記台座本体の前記チョークコイルを載置する面とは逆の面に形成され、前記回路基板に配設されて、前記回路基板と前記台座本体とを予め定められた間隔で離隔させる脚部と、を備え、前記台座本体には、前記チョークコイルに整列巻きされた巻線の異なる複数の巻回数に応じた位置に、該巻線を通す複数の孔部が形成されている。   A choke coil pedestal according to claim 1 of the present invention is a choke coil pedestal to be incorporated in a circuit board, and includes a plate-like pedestal body on which a choke coil is placed on one side, and the choke coil of the pedestal body. A leg portion that is formed on a surface opposite to the surface on which the circuit board is placed, and is disposed on the circuit board and separates the circuit board and the pedestal body at a predetermined interval. A plurality of holes for passing the windings are formed at positions corresponding to a plurality of different numbers of windings of the windings aligned and wound on the choke coil.

この構成では、載置されるチョークコイルの巻線の巻回数に応じた位置に、板状の台座本体に該巻線を通す複数の孔部が形成されている。したがって、整列巻きされた巻線を有し巻回数が異なる複数のチョークコイルについて台座を共通化することが可能となる。   In this configuration, a plurality of holes for passing the windings are formed in the plate-shaped base body at positions corresponding to the number of windings of the choke coil to be placed. Therefore, it is possible to make the pedestal common for a plurality of choke coils having windings that are aligned and having different numbers of turns.

さらにこの構成では、前記台座本体の前記チョークコイルを載置する面とは逆の面に前記回路基板に配設される脚部が形成され、前記回路基板と前記台座本体との間は、予め定められた間隔で離隔されている。したがって、前記脚部によって絶縁距離を確保することができるので、開口部の面積を増加させることが可能となり、巻線の異なる複数の巻回数に応じた位置に該巻線を通す複数の孔部を設けることが可能となっている。また、前記チョークコイルの端子の位置決めを容易にするために、前記複数の孔部のそれぞれの面積を拡大することも可能である。さらに、従来デッドスペースとなっていたチョークコイル台座下の回路基板上に、例えばコンデンサ等の部品を配設することもできる。   Further, in this configuration, a leg portion disposed on the circuit board is formed on a surface opposite to the surface on which the choke coil of the pedestal body is placed, and the gap between the circuit board and the pedestal body is previously set. They are separated by a set interval. Therefore, since the insulation distance can be ensured by the leg portion, the area of the opening can be increased, and a plurality of hole portions through which the winding passes at positions corresponding to a plurality of different winding numbers. Can be provided. Further, in order to facilitate positioning of the terminals of the choke coil, it is possible to enlarge the area of each of the plurality of holes. Furthermore, a component such as a capacitor can be disposed on the circuit board under the choke coil base, which has conventionally been a dead space.

本発明の請求項2に係るチョークコイル台座は、請求項1に係るチョークコイル台座において、前記台座本体が、チョークコイルの外形に応じた形状とされている。この構成によれば、前記台座本体の面積が必要最小限に抑えられるので、よりデッドスペースが削減される。   A choke coil base according to a second aspect of the present invention is the choke coil base according to the first aspect, wherein the base body has a shape corresponding to the outer shape of the choke coil. According to this configuration, since the area of the pedestal main body is suppressed to a necessary minimum, dead space is further reduced.

本発明の請求項3に係るチョークコイル台座は、請求項1または2に係るチョークコイル台座において、前記台座本体は、前記チョークコイルのコアが平面視で横向きに見える向きに載置可能な形状であって、載置される前記チョークコイルの外形に応じた形状を有する。   The choke coil base according to claim 3 of the present invention is the choke coil base according to claim 1 or 2, wherein the base body has a shape that can be placed in a direction in which the core of the choke coil can be seen sideways in plan view. And has a shape corresponding to the outer shape of the mounted choke coil.

この構成によれば、前記チョークコイルは、前記チョークコイルのコアが平面視で横向きに見える向きに載置される。つまり、前記チョークコイルが前記回路基板表面に直立するのではなく、倒された状態で該回路基板表面に載置されている。したがって、前記回路基板表面からチョークコイル頂部までの高さが抑えられる。しかも、前記台座本体は、載置される前記チョークコイルの外形に応じた形状を有するので、該台座本体の面積が必要最小限に抑えられる。   According to this configuration, the choke coil is placed in such a direction that the core of the choke coil can be seen sideways in a plan view. That is, the choke coil does not stand upright on the circuit board surface but is placed on the circuit board surface in a tilted state. Therefore, the height from the surface of the circuit board to the top of the choke coil is suppressed. In addition, since the pedestal body has a shape corresponding to the outer shape of the mounted choke coil, the area of the pedestal body can be minimized.

本発明の請求項4に係るチョークコイル台座は、請求項1〜3に係るチョークコイル台座が、射出成形によって、前記台座本体と前記脚部とが一体に形成される。この構成によれば、前記脚部と前記台座本体とを別体に形成する場合とは異なり、例えば接着あるいは溶着等によって該脚部を該台座本体に結合する工程が不要となる。したがって、前記脚部と前記台座本体との接合部の強度が向上するとともに、低コストでチョークコイル台座を製作することが可能となる。   According to a fourth aspect of the present invention, in the choke coil base according to the first to third aspects, the base body and the leg portion are integrally formed by injection molding of the choke coil base according to the first to third aspects. According to this configuration, unlike the case where the leg portion and the pedestal main body are formed separately, a step of joining the leg portion to the pedestal main body by, for example, adhesion or welding is not required. Therefore, the strength of the joint portion between the leg portion and the pedestal main body is improved, and the choke coil pedestal can be manufactured at low cost.

本発明の請求項5に係る空気調和機のコントローラは、トロイダルコイルが請求項3または4のいずれかに記載のチョークコイル台座に載置されて回路基板に組込まれている。この構成によれば、前記回路基板表面からトロイダルコイル頂部までの高さが抑えられ、かつ、チョークコイル台座下の回路基板上に部品を配設して該回路基板の面積を減らすことができるので、該回路基板が組込まれるコントローラを小型化することができる。   In a controller for an air conditioner according to a fifth aspect of the present invention, the toroidal coil is mounted on the choke coil base according to the third or fourth aspect and is incorporated in the circuit board. According to this configuration, the height from the surface of the circuit board to the top of the toroidal coil can be suppressed, and the area of the circuit board can be reduced by arranging components on the circuit board under the choke coil base. The controller in which the circuit board is incorporated can be reduced in size.

本発明に係るチョークコイル台座によれば、巻回数が異なるチョークコイルを用いる場合にも、絶縁距離を確保しながらも、チョークコイル毎に台座を用意することなく容易に位置決めをすることができる。さらに、従来デッドスペースとなっていたチョークコイル台座下の回路基板上に、部品を配設することができる。したがって、チョークコイル台座を共通化できるのでコスト削減が可能となり、さらに、チョークコイル台座下の回路基板上に部品を配設できるので前記回路基板の小型化が可能となり、該回路基板を組込んだ装置を小型化することができる。   According to the choke coil base according to the present invention, even when a choke coil having a different number of turns is used, positioning can be easily performed without preparing a base for each choke coil while ensuring an insulation distance. Furthermore, components can be disposed on a circuit board under a choke coil base that has conventionally been a dead space. Therefore, since the choke coil base can be made common, the cost can be reduced. Further, since the components can be arranged on the circuit board under the choke coil base, the circuit board can be miniaturized, and the circuit board is incorporated. The apparatus can be miniaturized.

以下、図面に基づいて本発明の実施形態につき詳細に説明する。図1は、本発明の一実施形態に係る空気調和機のコントローラ用のノイズフィルタ用基板の一例を示す。図1(A)は、ノイズフィルタ用基板1の平面図であり、図1(B)は、ノイズフィルタ用基板1の正面図である。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows an example of a noise filter substrate for a controller of an air conditioner according to an embodiment of the present invention. FIG. 1A is a plan view of the noise filter substrate 1, and FIG. 1B is a front view of the noise filter substrate 1.

ノイズフィルタ用基板1は、トロイダルコイル200が、本発明の一実施形態に係るチョークコイル台座100に載置されてプリント基板300に配設されている。なお、トロイダルコイル200の巻線の端部にはリード端子が接続され、該リード端子はプリント基板300に接続されているが、図1では、チョークコイル台座100の説明のために該リード端子の図示を省略している。   The noise filter substrate 1 has a toroidal coil 200 mounted on a printed circuit board 300 mounted on a choke coil base 100 according to an embodiment of the present invention. A lead terminal is connected to the end of the winding of the toroidal coil 200, and the lead terminal is connected to the printed circuit board 300. In FIG. The illustration is omitted.

トロイダルコイル200は、本実施形態では三相のトロイダルコイルであり、コモンモードノイズを除去するためのコモンモードチョークコイルとして用いられている。巻線の断面積を大きくして、空気調和機のコントローラに流れる例えば45Aの大電流に対応するために、トロイダルコイル200の巻線には、エッジワイズ巻きされた平角線が用いられている。   In this embodiment, the toroidal coil 200 is a three-phase toroidal coil, and is used as a common mode choke coil for removing common mode noise. In order to increase the cross-sectional area of the winding and cope with a large current of, for example, 45 A flowing through the controller of the air conditioner, a rectangular wire that is edgewise wound is used for the winding of the toroidal coil 200.

空気調和機のコントローラ等を構成する電気回路に、電気的ノイズが混入すると、機器の誤作動等の不具合を生じることがある。そのため通常は、該電気回路に電気的ノイズを除去するためのノイズフィルタ回路を設ける。本実施形態では、前記ノイズフィルタ回路をノイズフィルタ用基板1に形成して空気調和機のコントローラに実装している。ノイズフィルタリングの対象は、コントローラを構成する電気回路に流れるコモンモードノイズである。   If electrical noise is mixed in the electrical circuit that constitutes the controller or the like of the air conditioner, problems such as malfunction of the device may occur. Therefore, normally, a noise filter circuit for removing electrical noise is provided in the electrical circuit. In the present embodiment, the noise filter circuit is formed on the noise filter substrate 1 and mounted on the controller of the air conditioner. The target of noise filtering is common mode noise that flows in the electric circuit constituting the controller.

チョークコイル台座100には、例えばPBT(Polybutylene Terephthalate)樹脂やPET(Polyetylene Terephthalate)樹脂、PP(Polypropylene)樹脂等の電気抵抗率の高い熱可塑性樹脂が用いられる。プリント基板300とトロイダルコイル200との間に、チョークコイル台座100が介在することで、両者の絶縁距離が確保される。また、トロイダルコイル200をチョークコイル台座100に載置することで、直接プリント基板300に実装するよりも、トロイダルコイル200の実装が容易になる。   For the choke coil pedestal 100, for example, a thermoplastic resin having a high electrical resistivity such as PBT (Polybutylene Terephthalate) resin, PET (Polyethylene Terephthalate) resin, or PP (Polypropylene) resin is used. Since the choke coil base 100 is interposed between the printed board 300 and the toroidal coil 200, an insulation distance between the two is ensured. Further, mounting the toroidal coil 200 on the choke coil base 100 makes it easier to mount the toroidal coil 200 than mounting it directly on the printed circuit board 300.

チョークコイル台座100は、トロイダルコイル200を平面視で環状に見える向き(横向き)に載置する円盤状の台座本体110と、台座本体110のトロイダルコイル200を載置する面とは逆の面に形成され、プリント基板300に配設される円柱状の脚部120と、を備える。   The choke coil pedestal 100 has a disk-shaped pedestal main body 110 for placing the toroidal coil 200 in a ring-like direction (sideways) in plan view, and a surface opposite to the surface on which the toroidal coil 200 is placed. And a columnar leg 120 formed and disposed on the printed circuit board 300.

台座本体110と脚部120とは、前記熱可塑性樹脂を射出成形することによって一体に成形される。そのため、脚部120と台座本体110とを別体に形成する場合とは異なり、例えば接着あるいは溶着等によって脚部120を台座本体110に結合する工程が不要となる。したがって、脚部120と台座本体110との結合部の強度が向上するとともに、低コストでチョークコイル台座100を製作することが可能となる。   The pedestal main body 110 and the leg portion 120 are integrally formed by injection molding of the thermoplastic resin. Therefore, unlike the case where the leg 120 and the pedestal main body 110 are formed separately, a step of joining the leg 120 to the pedestal main body 110 by, for example, bonding or welding becomes unnecessary. Therefore, the strength of the joint portion between the leg portion 120 and the pedestal main body 110 is improved, and the choke coil pedestal 100 can be manufactured at a low cost.

台座本体110は、絶縁効果を確保し、かつ、その面積を最小限に抑えるため、トロイダルコイル200の巻線外周部の直径よりも若干大きな直径とされている。必要最小限の面積に台座本体110を形成することで、デッドスペースが最小限に抑えられるとともに、チョークコイル台座100が最小限の材料で形成されることになるため、コスト削減が可能となる。脚部120の高さは例えば3mmであり、プリント基板300と台座本体110との間は、この3mmの間隔で離隔される。   The pedestal main body 110 has a diameter slightly larger than the diameter of the outer periphery of the winding of the toroidal coil 200 in order to ensure an insulating effect and minimize the area. By forming the pedestal main body 110 in the necessary minimum area, dead space is minimized, and the choke coil pedestal 100 is formed of a minimum material, so that the cost can be reduced. The height of the leg portion 120 is 3 mm, for example, and the printed circuit board 300 and the pedestal main body 110 are separated from each other at a distance of 3 mm.

FIG. FIGS. 3A and 3B are diagrams showing an example of a conventional choke coil base. FIG. 3A is a plan view and FIG. 3B is a front view, similarly to FIG.

本発明の一実施形態に係るチョークコイル台座100について、従来のチョークコイル台座と対比しながら以下に説明する。   A choke coil pedestal 100 according to an embodiment of the present invention will be described below in comparison with a conventional choke coil pedestal.

従来のチョークコイル台座は、三相用のトロイダルコイルを載置する場合、トロイダルコイルの巻線の終端部に接続された計6つの端子を通すために、円盤状の台座本体110外縁部付近(挿入口111a)と中心部付近(挿入口111b)とに3つずつ均等の間隔で挿入口(孔部)が設けられている。すなわち、挿入口数は、前記端子の数と同数である。なお、前記端子の形状に合わせて、図3の例では、挿入口111a、111bの形状は略矩形とされ、挿入口111aは、その長さ方向が台座本体の中心に向かって形成され、挿入口111bは、その長さ方向が挿入口111aの長さ方向と略30°をなすように形成されている。 When a toroidal coil for a three-phase is placed on a conventional choke coil pedestal, the outer periphery of the disk-shaped pedestal main body 110 is used in order to pass a total of six terminals connected to the terminal end of the toroidal coil winding ( Three insertion ports (holes) are provided at equal intervals in the insertion port 111a 1 ) and in the vicinity of the center (insertion port 111b). That is, the number of insertion ports is the same as the number of the terminals. In addition, according to the shape of the terminal, in the example of FIG. 3, the shapes of the insertion openings 111a 1 and 111b are substantially rectangular, and the insertion opening 111a 1 is formed so that the length direction thereof is toward the center of the pedestal main body. , the insertion opening 111b, the length direction is formed so as to form a substantially 30 ° to the longitudinal direction of the insertion opening 111a 1.

ところで、トロイダルコイル200の巻線が整列巻きされている場合、巻回数が異なると巻線終端に接続された端子の位置が変化する。この複数の位置に対応させて、本実施形態に係るチョークコイル台座100の外縁部付近の挿入口は形成されている。すなわち、従来の挿入口111aに加えて、挿入口111a〜111aがさらに形成されている。挿入口111a〜111aは、その長さ方向が台座本体の中心に向かって形成され、かつ、その長さ方向が挿入口111bの長さ方向となす角度が、順次減少する位置に形成されている。 By the way, when the windings of the toroidal coil 200 are aligned, if the number of windings is different, the position of the terminal connected to the end of the winding changes. Corresponding to the plurality of positions, an insertion port near the outer edge of the choke coil base 100 according to the present embodiment is formed. That is, in addition to the conventional insertion opening 111a 1, the insertion opening 111a 2 ~111a 4 is further formed. The insertion ports 111a 2 to 111a 4 are formed at positions where the length direction is formed toward the center of the pedestal main body, and the angle between the length direction and the length direction of the insertion port 111b is sequentially reduced. ing.

台座本体110の外縁部に位置する端子1つに対して、4つの挿入口111a〜111aが用意されているので、整列巻きされたチョークコイルの巻線の巻回数が異なっても、いずれかの挿入口に端子を通すことができる。 Since four insertion ports 111a 1 to 111a 4 are prepared for one terminal located at the outer edge of the pedestal main body 110, even if the number of windings of the aligned choke coil is different, The terminal can be passed through the insertion slot.

従来のチョークコイル台座は、円盤状の台座本体110のみからなる。一方、本発明に係るチョークコイル台座100は、台座本体110のトロイダルコイル200を載置する面とは逆の面に形成された4本の脚部120をさらに備えている。脚部120のうちの1本は台座本体110の中心に、3本は台座本体110の外縁部に均等の間隔、かつトロイダルコイル200の端子と干渉しない位置に形成されている。   The conventional choke coil pedestal comprises only a disk-shaped pedestal main body 110. On the other hand, the choke coil base 100 according to the present invention further includes four leg portions 120 formed on the surface opposite to the surface on which the toroidal coil 200 of the base body 110 is placed. One of the leg portions 120 is formed at the center of the pedestal main body 110, and three are formed at equal intervals on the outer edge portion of the pedestal main body 110 and at positions that do not interfere with the terminals of the toroidal coil 200.

プリント基板300と台座本体110との間は、脚部120の高さ(本実施形態では3mm)で離隔されることになる。すなわち、絶縁距離が確保されるので、台座本体110の開口面積を増やすことができる。したがって、従来のチョークコイル台座が備える挿入口111aおよび111bに加えて、挿入口111a〜111aを設けることが可能となっている。さらに、各挿入口の面積を拡大して端子の位置決めを容易にすることも可能である。 The printed circuit board 300 and the pedestal main body 110 are separated by the height of the leg portion 120 (3 mm in this embodiment). That is, since the insulation distance is secured, the opening area of the pedestal main body 110 can be increased. Therefore, it is possible to provide the insertion ports 111a 2 to 111a 4 in addition to the insertion ports 111a 1 and 111b provided in the conventional choke coil base. Furthermore, it is possible to facilitate positioning of the terminals by increasing the area of each insertion slot.

脚部120によって離隔されるプリント基板300と台座本体110との間のスペースには、プリント基板300上に図略のコンデンサ等の部品が実装されている。従来デッドスペースとなっていたチョークコイル台座下の回路基板上に部品が実装されているので、従来のコントローラよりもプリント基板300を小型化することが可能となっている。   Components such as capacitors (not shown) are mounted on the printed circuit board 300 in the space between the printed circuit board 300 and the pedestal main body 110 separated by the leg portions 120. Since the components are mounted on the circuit board under the choke coil base, which has conventionally become a dead space, the printed circuit board 300 can be made smaller than the conventional controller.

以上説明したように、上記実施形態に係るチョークコイル台座100によれば、従来、巻線の巻回数が異なるトロイダルコア毎に製作していたチョークコイル台座を共通化できるので、コスト削減が可能となる。また、上記実施形態に係る空気調和機のコントローラは、上記実施形態に係るチョークコイル台座100を採用することで、プリント基板300の表面からトロイダルコイル頂部までの高さが抑えられ、かつ、プリント基板300上のチョークコイル台座100に覆われた部分に部品を配設してプリント基板300の面積を減らすことが可能となるので、従来の空気調和機のコントローラよりも小型化することができる。   As described above, according to the choke coil pedestal 100 according to the above embodiment, the choke coil pedestal conventionally manufactured for each toroidal core having a different number of winding turns can be used in common, so that the cost can be reduced. Become. Moreover, the controller of the air conditioner according to the above embodiment employs the choke coil base 100 according to the above embodiment, thereby suppressing the height from the surface of the printed circuit board 300 to the top of the toroidal coil, and the printed circuit board. Since parts can be disposed in the portion of the board 300 covered with the choke coil base 100 to reduce the area of the printed circuit board 300, it can be made smaller than a controller of a conventional air conditioner.

以上、本発明の実施形態に係るチョークコイル台座100および空気調和機のコントローラについて説明したが、本発明はこれに限定されるものではなく、例えば次のような変形実施形態を取ることもできる。   As described above, the choke coil base 100 and the air conditioner controller according to the embodiment of the present invention have been described. However, the present invention is not limited to this, and for example, the following modified embodiment can be taken.

(1)上記実施形態では、チョークコイル台座100は、三相のトロイダルコイル200を載置するが、載置されるトロイダルコイルが二相あるいは四相であっても本発明は適用できる。また、トロイダルコイルに限らず載置されるコイルの巻線が整列巻きであれば、本発明を適用できる。   (1) In the above embodiment, the choke coil base 100 mounts the three-phase toroidal coil 200, but the present invention can be applied even if the toroidal coil to be mounted is two-phase or four-phase. In addition, the present invention can be applied as long as the winding of a coil to be placed is not limited to a toroidal coil but is an aligned winding.

(2)上記実施形態では、脚部120は円柱状に形成されているが、脚部の形状はこれに限定されるものではなく、絶縁距離を確保できる高さ(上記実施形態では3mm)に形成されていれば、例えば角柱状等の異なる形状であってもよい。   (2) In the above embodiment, the leg portion 120 is formed in a columnar shape, but the shape of the leg portion is not limited to this, and is high enough to secure an insulation distance (3 mm in the above embodiment). As long as it is formed, it may have a different shape such as a prismatic shape.

(3)上記実施形態では、トロイダルコイルを、コモンモードノイズを除去するコモンモードチョークコイルとして用いているが、トロイダルコイルは、ノーマルモードノイズを除去するノーマルモードチョークコイルとして用いてもよく、また、トロイダルコイルの用途はノイズフィルタに限られるものでもない。   (3) In the above embodiment, the toroidal coil is used as a common mode choke coil for removing common mode noise. However, the toroidal coil may be used as a normal mode choke coil for removing normal mode noise. The use of toroidal coils is not limited to noise filters.
