Description
本発明は、非接触給電装置に用いられる送電コイルなど電線を用いた電気回路において、電流の経路が交差する回路を構成する際に用いて好適な電線接続デバイスに関する。 The present invention relates to an electric wire connection device suitable for use in configuring a circuit in which current paths intersect in an electric circuit using electric wires such as a power transmission coil used in a non-contact power supply apparatus.
近年、電気自動車などの電気で駆動する移動車両に、機械的な接触なく電力を供給する非接触給電装置の開発、実用化が行われている。非接触給電装置は、電力を供給する送電コイルを備えた送電回路と、供給された電力を受電する受電コイルを備えた受電側回路から主に構成されている。この非接触給電装置は、送電コイルと受電コイルとの電磁誘導作用に基づいて給電が行われる。即ち、送電コイルに流れる電流によって発生した磁界によって受電コイルに電流が誘導されて給電が行われる。 2. Description of the Related Art In recent years, a non-contact power supply device that supplies electric power to a moving vehicle driven by electricity such as an electric vehicle without mechanical contact has been developed and put into practical use. The non-contact power feeding apparatus mainly includes a power transmission circuit including a power transmission coil that supplies power and a power reception side circuit including a power reception coil that receives the supplied power. This non-contact power feeding device performs power feeding based on the electromagnetic induction action between the power transmission coil and the power receiving coil. That is, the current is induced in the power receiving coil by the magnetic field generated by the current flowing in the power transmitting coil, and power is supplied.
送電回路は、高周波の交流を発生させる電源と、送電コイルから主に構成されている。送電コイルは、略Ｕ字状に曲げられた電線の向かい合う部分が平行になる様にして配置された平面状のループコイルであり、移動車両が通行する路面や路肩の壁などに、車両の進行方向に沿って配置されるものである。受電回路は、送電コイルから所定の距離だけ離れて配置される受電コイルと、受電コイルが接続されたコンバータなどの整流回路等から主に構成されている。受電回路はコンバータなどを介してバッテリーやモーターの駆動回路などに接続され、受電した電力を供給する。 The power transmission circuit is mainly composed of a power source that generates high-frequency alternating current and a power transmission coil. The power transmission coil is a flat loop coil that is arranged so that the facing portions of the electric wires bent in a substantially U-shape are parallel to each other, and the vehicle travels on the road surface or the shoulder wall where the moving vehicle passes. It is arranged along the direction. The power receiving circuit mainly includes a power receiving coil disposed at a predetermined distance from the power transmitting coil, a rectifier circuit such as a converter to which the power receiving coil is connected, and the like. The power receiving circuit is connected to a battery or a motor driving circuit through a converter or the like, and supplies the received power.
この様な非接触給電装置では、送電コイルが発生する高周波磁界が、例えば移動車両の軌道に沿って配置されている他のケーブルや導電性の部品など、受電コイル以外の部分に電流を誘導し、障害を発生させてしまうという問題がある。この問題を解決するため、送電コイルの電線が平行に配置されている部分にて２本の電線を交差させ、それぞれの電流の経路の位置を入れ替えることが行われている（例えば特許文献１参照。）。即ち、２本の電線を交差させてその配置位置を入れ替え、交差した他方の電線が延びていた方向に一方の電線を配置して、２本の電線の配置位置を入れかえる。なお、以降において前述の様に電線を交差させて電流の経路の位置を入れ替えて配置することを「捻架を設ける」とも記載する。また、この電線が交差された部分を含む電線の部分を「捻架」とも記載する。この様にして送電コイルの複数箇所に捻架を設けると、送電コイルは、長手方向に捻った様な形となり、複数のループが形成されることになる（図６参照。）。 In such a non-contact power supply device, the high-frequency magnetic field generated by the power transmission coil induces a current in a portion other than the power reception coil, such as other cables and conductive parts arranged along the track of the moving vehicle. There is a problem of causing a failure. In order to solve this problem, two electric wires are crossed at a portion where the electric wires of the power transmission coil are arranged in parallel, and the positions of the respective current paths are exchanged (for example, see Patent Document 1). .) That is, two electric wires are crossed and the arrangement positions thereof are changed, and one electric wire is arranged in a direction in which the other crossed electric wires are extended to change the arrangement positions of the two electric wires. Hereinafter, as described above, arranging the electric wires so as to cross each other and changing the position of the current path is also referred to as “providing a twist”. Moreover, the part of the electric wire including the part where this electric wire cross | intersected is also described as "twist". When twists are provided at a plurality of locations of the power transmission coil in this manner, the power transmission coil has a shape that is twisted in the longitudinal direction, and a plurality of loops are formed (see FIG. 6).
この様にされた送電コイルに電流が流れると、捻架が設けられた箇所を挟んで隣り合うループに、それぞれ逆向きの磁界が発生する。このため、例えば送電コイルと隣接してケーブルが配線されている場合には、ケーブルに隣接する送電コイルのループの区間毎に、それぞれ逆向きの電流が誘導される。結果としてケーブルに流れる電流は互いに打ち消され、障害の発生が防がれる。 When a current flows through the power transmission coil thus configured, a magnetic field in the opposite direction is generated in each adjacent loop across the portion where the twist is provided. For this reason, for example, when a cable is wired adjacent to the power transmission coil, currents in opposite directions are induced for each section of the loop of the power transmission coil adjacent to the cable. As a result, the currents flowing in the cables cancel each other, and a failure is prevented.
一般に、非接触給電装置の送電コイルを設置する場合には、移動車両が通行する路面の軌道などに沿って、電線を所定の間隔で略平行に配置して送電コイルを形成する。上述の特許文献１に記載された技術では、この電線を設置する際に、所定の箇所で電線を交差させて捻架を設ける必要がある。 Generally, when installing a power transmission coil of a non-contact power feeding device, a power transmission coil is formed by arranging electric wires substantially parallel at predetermined intervals along a track of a road surface on which a moving vehicle passes. In the technique described in Patent Document 1 described above, when installing this electric wire, it is necessary to provide a twisted crossing the electric wire at a predetermined location.
しかしながら、電気自動車などの移動車両に電力を供給する送電コイルは、より多くの電流を流す必要があり、太い径の電線が一般に用いられる。その様な電線は容易に曲げることができないため、捻架を設ける作業に多くの労力を要してしまうという問題があった。また、捻架を設けた箇所及び捻架を設けるために電線を曲げて配置した箇所では、給電効率が悪くなってしまうという問題もあった。 However, a power transmission coil that supplies electric power to a moving vehicle such as an electric vehicle needs to pass a larger amount of current, and a thick wire is generally used. Since such an electric wire cannot be bent easily, there has been a problem that a lot of labor is required for the work of providing a twisted frame. In addition, there is a problem that the feeding efficiency is deteriorated at a portion where a twist is provided and a portion where an electric wire is bent to provide the twist.
本発明は、上記の課題を解決するためになされたものであって、容易に捻架を設けることが可能で、給電効率のよい非接触給電装置の送電コイルを構成することができる電線接続デバイスを提供することを目的とする。 The present invention has been made in order to solve the above-described problems, and can be easily provided with a twist, and can constitute a power transmission coil of a non-contact power feeding device with high power feeding efficiency.

＜作用の説明＞
続いて、本発明に係る電線接続デバイス１の作用について、主に図４を参照して電線接続デバイス１Ａを例に説明を行う。なお、電線接続デバイス１Ｂ〜１Ｄの作用も電線接続デバイス１Ａと同様である。
<Description of action>
Then, the effect | action of the electric wire connection device 1 which concerns on this invention is demonstrated taking the electric wire connection device 1A as an example mainly with reference to FIG. In addition, the effect | action of electric wire connection device 1B-1D is the same as that of electric wire connection device 1A.
はじめに電源３００から電流Ｉ１が、電線接続デバイス１Ａに向かって電線５０Ｌを流れる例に適用して説明を行う。電線５０Ｌを流れた電流Ｉ１は、接続部１１ａから電線接続デバイス１Ａに入力される。接続部１１ａから入力された電流Ｉ１は、導電部３を流れて接続部１４ａから出力され、電線接続デバイス１Ａから離れる方向に向かって電線５１Ｒを流れる。電線５１Ｒを流れた電流は、電線対５１よりも前側に配置されている送電コイル２００の他の部分を流れ、電流Ｉ１とは逆向きの電流Ｉ２として電線５１Ｌを電線接続デバイス１Ａに向かって流れる。 First , description will be made by applying the example in which the current I 1 flows from the power source 300 through the electric wire 50L toward the electric wire connecting device 1A. Current I 1 flowing through the wire 50L is input from the connection portion 11a to the wire connecting device 1A. Current I 1 which is input from the connection portion 11a, the conductive portion 3 of the flow being output from the connecting portion 14a, flows through the wire 51R in a direction away from the wire connecting device 1A. Current flowing through the wire 51R flows through other parts of the power transmission coil 200 disposed in front of the wire pair 51, toward the wire 51L to the wire connecting device 1A as the current I 2 opposite to the current I 1 Flowing.
電線５１Ｌを流れた電流Ｉ２は、接続部１３ａから電線接続デバイス１Ａに入力され、導電部４を流れて接続部１２ａから出力される。接続部１２ａから出力された電流Ｉ２は、電線５０Ｒを流れて電源３００に戻る（図４（ａ）参照。）。 The current I 2 that has flowed through the electric wire 51L is input from the connection portion 13a to the electric wire connection device 1A, flows through the conductive portion 4, and is output from the connection portion 12a. Current I 2 which is output from the connection portion 12a is returned to the power source 300 flows through the wire 50R (see FIG. 4 (a).).
電源３００から電流Ｉ１が、電線接続デバイス１Ａに向かって電線５０Ｒを流れる場合には、上記とは逆の順番で電流が流れる。即ち、電源３００から電流Ｉ１が、電線接続デバイス１Ａに向かう方向に電線５０Ｒを流れ、接続部１２ａに入力される。接続部１４ａに入力された電流Ｉ１は、導電部４を流れ、接続部１３ａから出力されて、電線接続デバイス１Ａから離れる方向に向かって電線５１Ｌを流れる。そして電線５１Ｌを流れた電流Ｉ１は、電線対５１よりも前側に配置されている送電コイル２００の他の部分を流れ、電流Ｉ１とは逆向きの電流Ｉ２として、電線接続デバイス１Ａに向かって電線５１Ｒを流れ、接続部１４ａに入力される。接続部１４ａに入力された電流Ｉ２は、接続部１１ａから出力されて電線５０Ｌを流れて電源３００に戻る。 Current I 1 from the power source 300 is, when flowing through the wire 50R towards the wire connecting device 1A, a current flows in the reverse order to the above. That is, the current I 1 from the power supply 300 flows through the electric wire 50R in the direction toward the electric wire connecting device 1A and is input to the connecting portion 12a. Connecting portion current I 1 that is input to the 14a is a conductive portion 4 flows, is output from the connection section 13a, through the wire 51L in a direction away from the wire connecting device 1A. The current I 1 flowing through the wire 51L flows through other parts of the power transmission coil 200 disposed in front of the wire pair 51, a current I 2 in the reverse direction to the current I 1, the wire connecting device 1A It flows through the electric wire 51R toward the connection portion 14a. Current I 2 which is input to the connection portion 14a is output from the connecting portion 11a returns to the power source 300 flows through the wire 50L.
次に、電線接続デバイス１を用いた送電コイル２００の作用について主に図５を参照し説明を行う。以降の説明では、図５に示されているように、電源３００から電線５０Ｌに電流Ｉ１が前側に向かって流れ、電線５０Ｒに、電流Ｉ１とは逆向きの電流Ｉ２が電源３００に向かって流れる例に適用して以降の説明を行う。 Next, the operation of the power transmission coil 200 using the wire connection device 1 will be described mainly with reference to FIG. In the following description, as shown in Figure 5, current flows I 1 from the power supply 300 to the electric wire 50L is toward the front, the wire 50R, the current I 2 power supply 300 opposite to the current I 1 The following description will be made by applying to an example of flowing toward.
電源３００から、電線接続デバイス１Ａに向かって電線５０Ｌを流れた電流Ｉ１は、電線接続デバイス１Ａの接続部１１ａに入力され、接続部１４ａから出力されて、電線５１Ｒを流れる。電線５１Ｒを流れた電流Ｉ１は、電線接続デバイス１Ｂの接続部１２ｂに入力され、接続部１３ｂから出力されて、電線５２Ｌを流れる。電流Ｉ１は同様に、電線接続デバイス１Ｃに入力され、続いて電線５３Ｒを流れて電線接続デバイス１Ｄの接続部１２ｄに入力される。電線接続デバイス１Ｄに入力された電流Ｉ１は、接続部１３ｄから出力されて、電線５４を流れて接続部１４ｄに入力される。接続部１４ｄに入力された電流Ｉ１は、電流Ｉ１とは逆向きの電流Ｉ２として接続部１１ｄから出力され、電線５３Ｌを流れ、電線接続デバイス１Ｃの接続部１３ｃに入力される。電流Ｉ２は、以降同様に電線５２Ｒ、電線接続デバイス１Ｂ、電線５１Ｌ、電線接続デバイス１Ａ、電線５０Ｒを流れて電源３００に戻る。 The current I 1 that has flowed through the electric wire 50L from the power supply 300 toward the electric wire connecting device 1A is input to the connecting portion 11a of the electric wire connecting device 1A, is output from the connecting portion 14a, and flows through the electric wire 51R. Current I 1 flowing through the wire 51R is input to the connection portion 12b of the wire connecting devices 1B, is output from the connection portion 13b, through the wire 52L. Current I 1 is likewise inputted to the wire connecting device 1C, is input to the connection portion 12d of the wire connection device 1D and followed by wire 53R flows. Current I 1 which is input to the wire connecting device 1D is output from the connection portion 13d, is inputted to the connecting portion 14d flows through the electric wire 54. Current I 1 which is input to the connection portion 14d, the current I 1 is output from the connection portion 11d as a current I 2 in the opposite direction, it flows through the electric wires 53L, are inputted to the connecting portion 13c of the wire connecting device 1C. Thereafter, the current I 2 returns to the power supply 300 through the electric wire 52R, the electric wire connection device 1B, the electric wire 51L, the electric wire connection device 1A, and the electric wire 50R.
この様に電流が流れると、例えば電線接続デバイス１Ａ、電線接続デバイス１Ｂ、電線５１Ｒ，５１Ｌにて囲まれた部分であるループＡＢの内側に、図５の裏側から表側に向かう方向に磁界が発生する。そしてこの発生した磁界によって、送電コイル２００の左側に平行に隣接して設けられているケーブル４００のループＡＢと隣り合う部分に、前側に向かう電流Ｉ３が誘導される。 When a current flows in this way, a magnetic field is generated in the direction from the back side to the front side in FIG. 5 inside the loop AB, which is a portion surrounded by the wire connection device 1A, the wire connection device 1B, and the wires 51R and 51L. To do. The generated magnetic field induces a current I 3 directed toward the front side in a portion adjacent to the loop AB of the cable 400 provided adjacent to the left side of the power transmission coil 200 in parallel.
また、電線接続デバイス１Ｂ、電線接続デバイス１Ｃ、電線５２Ｒ，５２Ｌにて囲まれた部分であるループＢＣの内側には、図５の表側から裏側に向かう方向に磁界が発生する。そしてこの発生した磁界によって、ケーブル４００のループＢＣと隣り合う部分に後側に向かう電流Ｉ４が誘導される。前述の様に、電線５１Ｒ〜５３Ｒ及び電線５１Ｌ〜５３Ｌはいずれもそれぞれ同じ長さであるため、ループＡＢとループＢＣの大きさは同一である。このため各ループにて生じる磁界の大きさは同一であり、当該磁界によってケーブル４００に誘導される電流の大きさは同一となる。このため、ループＡＢとループＢＣにて誘導された電流Ｉ３と電流Ｉ４はそれぞれ打ち消される。同様に他の隣接するループにて誘導される電流も互いに打ち消されるため、送電コイル２００に流れる電流による影響が低減される。 In addition, a magnetic field is generated in the direction from the front side to the back side in FIG. 5 inside the loop BC, which is a portion surrounded by the wire connection device 1B, the wire connection device 1C, and the wires 52R and 52L. The generated magnetic field induces a current I 4 directed rearward in a portion adjacent to the loop BC of the cable 400. As described above, since the electric wires 51R to 53R and the electric wires 51L to 53L have the same length, the sizes of the loop AB and the loop BC are the same. For this reason, the magnitude of the magnetic field generated in each loop is the same, and the magnitude of the current induced in the cable 400 by the magnetic field is the same. For this reason, the currents I 3 and I 4 induced in the loop AB and the loop BC are respectively canceled. Similarly, currents induced in other adjacent loops cancel each other, so that the influence of the current flowing in the power transmission coil 200 is reduced.
上記の構成からなる電線接続デバイス１によれば、接続部１１と接続部１４を電気的に接続する導電部３と、接続部１２と接続部１３を電気的接続する導電部４が、それぞれ交差して設けられている。このため、二組の電線の間に電線接続デバイス１を配置して、それぞれの電線の端部を接続するだけの作業で、容易に捻架を設けることが可能となる。このため、例えば電気自動車などの移動車両に電力を供給するために太く曲げにくい電線を用いて送電コイルを構成する場合であっても、それぞれの電線の端部を電線接続デバイス１の接続部１１〜１４に接続するだけの作業で、容易に捻架を設けることができる。 According to the electric wire connecting device 1 having the above configuration, the conductive portion 3 that electrically connects the connecting portion 11 and the connecting portion 14 and the conductive portion 4 that electrically connects the connecting portion 12 and the connecting portion 13 intersect each other. Is provided. For this reason, it becomes possible to provide a twist easily by the operation | work which arrange | positions the electric wire connection device 1 between two sets of electric wires, and connects the edge part of each electric wire. For this reason, even if it is a case where a power transmission coil is comprised using the electric wire which is thick and hard to bend in order to supply electric power to moving vehicles, such as an electric vehicle, for example, the edge part of each electric wire is connected to the connection part 11 of the electric wire connection device 1. A twist can be easily provided by the work of connecting to -14.
また、本発明に係る電線接続デバイス１では、接続部１１は接続部１３と向かい合う位置、接続部１２は、接続部１４と向かい合う位置に配置されている。このため、移動車両の軌道に沿って平行に配置された電線の間に電線接続デバイス１を配置し、それぞれの電線の端部を接続部１１〜１４に接続するだけで容易に捻架を設けることができ、捻架を設けるために電線を徐々に曲げるといった追加の作業を行う必要がない。一般に電気自動車などの移動車両に電力を供給する送電コイルは、より多くの電流を流す必要があり、太い径の電線が一般に用いられるため、急な角度で曲げることが難しい。このため、従来、電線を交差させるために、捻架を設ける箇所から一定程度離れた部分から、それぞれの電線を近づける様に徐々に曲げて捻架を設けなければならなかった。このようにすると、本来の送電コイルの幅よりも狭い区間が長くなってしまう。捻架を設けた箇所や、２つの電線の間隔が狭い箇所では給電効率が悪くなるため、従来の方法で捻架を設けた場合には、給電効率の悪い区間が長くなってしまう。一方、本発明に係る電線接続デバイス１を用いれば、捻架を設けるために電線の配置の幅を狭める必要がなく、捻架を設けても給電効率が悪くなる区間を最小限に抑えることができる。このため、給電効率のよい非接触給電装置の送電コイルを構成することが可能となる。 Further, in the electric wire connecting device 1 according to the present invention, the connecting portion 11 is disposed at a position facing the connecting portion 13, and the connecting portion 12 is disposed at a position facing the connecting portion 14. For this reason, the electric wire connecting device 1 is arranged between electric wires arranged in parallel along the track of the moving vehicle, and a twist is easily provided only by connecting the end portions of the electric wires to the connecting portions 11 to 14. This eliminates the need for additional work such as bending the wire gradually to provide a twist. In general, a power transmission coil that supplies electric power to a moving vehicle such as an electric vehicle needs to pass a larger amount of current, and since a thick wire is generally used, it is difficult to bend at a steep angle. For this reason, conventionally, in order to cross the electric wires, it has been necessary to gradually twist the electric wires so that the electric wires are brought closer to each other from a portion apart from the portion where the twists are provided. If it does in this way, the section narrower than the width of the original power transmission coil will become long. Since the feeding efficiency is deteriorated at a place where a twist is provided or a place where the distance between two electric wires is narrow, when a twist is provided by a conventional method, a section where the feeding efficiency is poor becomes long. On the other hand, if the electric wire connecting device 1 according to the present invention is used, it is not necessary to narrow the arrangement width of the electric wires in order to provide a twist, and it is possible to minimize the section where the feeding efficiency is deteriorated even if the twist is provided. it can. For this reason, it becomes possible to comprise the power transmission coil of the non-contact electric power feeder with sufficient electric power feeding efficiency.
本発明にかかる電線接続デバイス１には、導電部３及び導電部４に、コンデンサ部２１〜２４が設けられている。通常、送電コイルには、例えば共振回路を形成するために、送電コイルのリアクタンスと対応した静電容量のコンデンサ（キャパシタ）が設けられる。本発明に係る電線接続デバイス１では、導電部３及び導電部４にコンデンサ部が設けられているため、送電回路に必要なコンデンサを送電コイル中に追加で設ける必要がない。また、送電回路に必要なコンデンサを分散して送電コイルに配置することが容易に行える。また、例えばコンデンサ部２１〜２４の静電容量を、送電コイルを構成する電線の所定の長さに応じた容量としておけば、例えば、移動車両の軌道を変更するなどの理由で、送電コイルの長さを変更する場合であっても、電線接続デバイス１を取り外し、あるいは追加で設置するだけの作業で送電コイルの共振調整を行うことも可能となる。また、送電コイルにおいてコンデンサ部が設けられる部分は、電流がコンデンサ部の形状等によっては流れる電流が電線の電流経路から離れる方向に拡散して流れてしまい、給電効率が低下してしまう場合がある。その様に給電効率に悪影響を及ぼすコンデンサ部を、同様に給電効率の悪い捻架の部分である電線接続デバイス１の内部に設けることで、給電効率の低下する部分の範囲を短くすることができる。 In the electric wire connection device 1 according to the present invention, capacitor portions 21 to 24 are provided in the conductive portion 3 and the conductive portion 4. Usually, the power transmission coil is provided with a capacitor (capacitor) having a capacitance corresponding to the reactance of the power transmission coil, for example, to form a resonance circuit. In the electric wire connection device 1 according to the present invention, since the capacitor portion is provided in the conductive portion 3 and the conductive portion 4, it is not necessary to additionally provide a capacitor necessary for the power transmission circuit in the power transmission coil. Moreover, it is possible to easily disperse the capacitors necessary for the power transmission circuit and arrange them in the power transmission coil. Further, for example, if the capacitance of the capacitor units 21 to 24 is set as a capacity according to a predetermined length of the electric wires constituting the power transmission coil, for example, for changing the track of the moving vehicle, the power transmission coil Even when the length is changed, it is possible to adjust the resonance of the power transmission coil by simply removing the wire connection device 1 or installing it additionally. Also, in the portion where the capacitor part is provided in the power transmission coil, the current may flow in a direction away from the current path of the electric wire depending on the shape of the capacitor part, etc., and the power supply efficiency may be reduced. . By providing the capacitor portion that adversely affects the power supply efficiency in the wire connection device 1 that is similarly a twisted portion having a low power supply efficiency, the range of the portion where the power supply efficiency decreases can be shortened. .
また、本発明にかかる電線接続デバイス１には、防水、防塵性能などの耐環境性能を有した筐体２が用いられている。このため、電線接続デバイス１を屋外に設置した場合であっても、周囲の環境変動の影響を受け、内部の導電部３や導電部４あるいはコンデンサ部２１〜２４等が悪影響を受けてしまうことを抑制できる。 In addition, the wire connection device 1 according to the present invention uses a housing 2 having environmental resistance such as waterproof and dustproof performance. For this reason, even if it is a case where the electric wire connection device 1 is installed outdoors, it will be influenced by the surrounding environmental fluctuation | variation, and the internal conductive part 3, the conductive part 4, or the capacitor | condenser parts 21-24 will be adversely affected. Can be suppressed.
また、本発明にかかる電線接続デバイス１の筐体２の寸法は、送電コイル２００を構成する電線を設置する際に必要とされる電線の設置空間の寸法と同一となっている。このため、電線接続デバイス１を配置するために、送電コイル２００を設置する路面等に追加の加工を行うことなく設置することができる。このため任意の場所に送電コイル２００を容易に設置することができる。このため、例えば送電コイル２００の長さを変更する作業を行う場合であっても容易にその作業を行うことができる。 Moreover, the dimension of the housing | casing 2 of the wire connection device 1 concerning this invention is the same as the dimension of the installation space of the electric wire required when installing the electric wire which comprises the power transmission coil 200. FIG. For this reason, in order to arrange | position the electric wire connection device 1, it can install, without performing an additional process on the road surface etc. which install the power transmission coil 200. FIG. For this reason, the power transmission coil 200 can be easily installed in an arbitrary place. For this reason, even if it is a case where the operation | work which changes the length of the power transmission coil 200 is performed, for example, the operation | work can be performed easily.
