Description

本発明は、電源に接続された給電コイルと、負荷に接続された受電コイルとを、電磁結合が成立する給電状態に置くことにより、給電部から受電部に対し電磁誘導により非接触で給電を行うことができる給電装置に係り、特に給電状態と非給電状態との間で位置関係を選択できる構造を備え、負荷の動作を行わない非給電状態では自動的に給電動作が停止して電流の消費を防止することができる給電装置に関するものである。   According to the present invention, a power feeding coil connected to a power source and a power receiving coil connected to a load are placed in a power feeding state in which electromagnetic coupling is established, so that power feeding from the power feeding unit to the power receiving unit by electromagnetic induction is performed without contact. In particular, it has a structure that can select the positional relationship between the power supply state and the non-power supply state, and the power supply operation stops automatically in the non-power supply state where the load operation is not performed. The present invention relates to a power supply device that can prevent consumption.

コネクター・ソケット等、機械的接触を介して電力を供給する給電装置は、水濡れの恐れのある場合や埃・砂等の堆積の恐れがある様な環境では、ショート・感電の可能性があるため使用することができなかった。   Power supply devices that supply power via mechanical contact, such as connectors and sockets, may cause short circuits or electric shock in environments where there is a risk of getting wet, or where there is a risk of accumulation of dust, sand, etc. Therefore could not be used.

この様な場所での使用に適した給電装置として、機械的な結合を用いずに電磁誘導を用いた非接触タイプの給電システムが提案されている。例えば、下記特許文献1には、自動車用の充電接続器であって、電源に接続された1次巻線11を有する円筒形の充電端子12を、自動車のバッテリーに接続される中空円筒形の2次巻線に対して着脱可能に挿入し、電磁誘導により非接触で給電を行うことができる給電装置が開示されている。
特開2002−84664号公報
As a power supply apparatus suitable for use in such a place, a non-contact type power supply system using electromagnetic induction without using mechanical coupling has been proposed. For example, in Patent Document 1 below, a charging connector for an automobile, which has a cylindrical charging terminal 12 having a primary winding 11 connected to a power source, is connected to an automobile battery. There is disclosed a power feeding device that can be detachably inserted into a secondary winding and can perform power feeding in a non-contact manner by electromagnetic induction.

As shown in FIG. 1, the power supply device of this example includes a power supply unit 2 including a power supply coil 1 and a power reception unit 4 including a power reception coil 3, and the power supply coil 1 and the power reception coil 3 configured separately. Is placed in a power supply state in which electromagnetic coupling is established, so that power is supplied from the power supply unit 2 to the power reception unit 4 in a non-contact manner by electromagnetic induction.

給電部2は、3つの小給電コイル5からなる給電コイル1と、後述する制御手段からの制御信号により交流で各小給電コイル5を駆動する3つの駆動回路6と、各駆動回路6と電源7との間の電源経路に設けられて電源電圧を一定電圧に変換する定電圧回路8と、前記電源経路に設けられた電流検出素子9と、各駆動回路6を制御する制御手段10とを有している。   The power feeding unit 2 includes a power feeding coil 1 including three small power feeding coils 5, three driving circuits 6 that drive each small power feeding coil 5 with an alternating current using a control signal from a control unit described later, and each driving circuit 6 and a power source. A constant voltage circuit 8 provided in a power supply path between the power supply path 7 and the power supply voltage for converting the power supply voltage into a constant voltage; a current detection element 9 provided in the power supply path; and a control means 10 for controlling each drive circuit 6 Have.

制御手段10は、基準となるクロックを発生させる発振回路11と、発振回路11の周波数を所望の周波数にして出力する分周回路12と、電流検出素子9の両端の電圧をデジタル信号に変えるA/D変換器13と、これら各回路等からの信号等を用いて前記各駆動回路6を制御する制御回路14とで構成される。制御回路14には、後述するように、駆動回路6を制御する際の判断基準となる各種の基準値が予め設定されている。   The control means 10 includes an oscillation circuit 11 that generates a reference clock, a frequency dividing circuit 12 that outputs the oscillation circuit 11 at a desired frequency, and a voltage at both ends of the current detection element 9 that changes to a digital signal A A / D converter 13 and a control circuit 14 for controlling each drive circuit 6 using signals from these circuits and the like. As will be described later, the control circuit 14 is set in advance with various reference values serving as determination criteria for controlling the drive circuit 6.

受電部4は、電磁誘導により交流電力を発生させる受電コイル3と、受電コイル3に接続された整流回路15を有する。整流回路15は、ダイオード16及びコンデンサー17を有し、受電コイル3に発生した交流電力を直流に変換して負荷20に供給する。   The power receiving unit 4 includes a power receiving coil 3 that generates AC power by electromagnetic induction, and a rectifier circuit 15 connected to the power receiving coil 3. The rectifier circuit 15 includes a diode 16 and a capacitor 17, converts alternating current power generated in the power receiving coil 3 into direct current, and supplies the direct current to the load 20.

図1及び図2に示すように、制御回路14からは相対的に高い周波数(本例では32kHz)又は相対的に低い周波数(本例では16kHz)のいずれか一方が、後述する手順に従った判断で選択され、基本信号S0として常時各駆動回路6に出力される。また、制御回路14からは、H又はLの選択信号S1(Hは選択、Lは非選択)が後述する手順に従って選択され、各駆動回路6に出力される。その結果、図2に示すように、給電コイル1に与えられる駆動信号(給電コイル1の波形)は、選択信号S1が入ると(Hになると)、基本信号S0の周波数に基いた交流波形となって給電コイル1に与えられ、これを駆動する。   As shown in FIG. 1 and FIG. 2, either a relatively high frequency (32 kHz in this example) or a relatively low frequency (16 kHz in this example) from the control circuit 14 follows the procedure described later. It is selected by judgment and is always output to each drive circuit 6 as a basic signal S0. Further, from the control circuit 14, an H or L selection signal S 1 (H is selected, L is not selected) is selected according to a procedure described later, and is output to each drive circuit 6. As a result, as shown in FIG. 2, when the selection signal S1 is input (when it becomes H), the drive signal given to the feeding coil 1 (the waveform of the feeding coil 1) is an AC waveform based on the frequency of the basic signal S0. Is applied to the feeding coil 1 to drive it.

次に、図3及び図4を参照して給電コイル1と受電コイル3のさらに具体的な形状等を説明する。
給電部2は、内径が一定である横断面円形の貫通孔21を中心に備えた中空円筒形の給電コイル1を有している。給電コイル1は、その他の給電部回路(前記制御手段10、定電圧回路8、電流検出素子9等)とともに外装材料22によって一体に封着された密閉構造となって給電部2を構成しており、コイルや回路等の電気的構成部分は種々の環境に耐えうる防水性・防湿性・防塵性を備えている。なお電源7は外部から供給される。そして、このような構造の給電部は、貫通孔21が上下方向に貫通するような姿勢で取り付け部30の開口31の内部に縦に設置されており、給電コイル1の貫通孔21の上端の開口が、取り付け部30の開口31内に隙間32をおいて配置されるように構成されている。
Next, more specific shapes and the like of the feeding coil 1 and the receiving coil 3 will be described with reference to FIGS. 3 and 4.
The power feeding unit 2 includes a hollow cylindrical power feeding coil 1 having a circular through hole 21 having a constant inner diameter at the center. The power supply coil 1 has a sealed structure integrally sealed with an exterior material 22 together with other power supply circuit (the control means 10, the constant voltage circuit 8, the current detection element 9, etc.) to form the power supply unit 2. The electrical components such as coils and circuits are waterproof, moistureproof, and dustproof to withstand various environments. The power source 7 is supplied from the outside. The power feeding unit having such a structure is installed vertically inside the opening 31 of the attachment unit 30 in such a posture that the through hole 21 penetrates in the vertical direction, and is arranged at the upper end of the through hole 21 of the power feeding coil 1. The opening is configured to be disposed in the opening 31 of the attachment portion 30 with a gap 32 therebetween.

受電部4は、給電部2の貫通孔21の軸線方向の長さの略2倍強の長さを有し、外装材料22と同様の材質からなる中実円柱状の基体40を備えている。そして、受電コイル3は、給電コイル1と同等の軸方向長さを有する磁性体(フェライト)23と、これの略全長に亘って巻かれた被覆導電線24とからなり、前記基体40の下端側(下半部)に封入されている。また、円柱状の基体40の上端には、整流回路(受電回路)15が封入されており、基体40内に封入された接続線を介して受電コイル3に接続されている。受電回路15からは導電線が基体40の外に封着状態で導出されており、図示しない負荷に接続されている。   The power receiving unit 4 includes a solid columnar base body 40 having a length approximately twice as long as the axial length of the through hole 21 of the power feeding unit 2 and made of the same material as the exterior material 22. . The power receiving coil 3 includes a magnetic body (ferrite) 23 having an axial length equivalent to that of the power feeding coil 1 and a covered conductive wire 24 wound over substantially the entire length thereof. It is enclosed on the side (lower half). Further, a rectifier circuit (power receiving circuit) 15 is sealed at the upper end of the cylindrical base body 40, and is connected to the power receiving coil 3 through a connection line sealed in the base body 40. A conductive wire is led out from the power receiving circuit 15 in a sealed state outside the base body 40 and is connected to a load (not shown).

また、この受電回路15が封入された基体40の上端は、受電コイル3が封入された本体部分よりも大径で外方に張り出した形状のフランジ部41として構成されており、さらにその側面側には基体40の下端側に向けて突出する支持部42が設けられている。この支持部42は棒状であり、受電コイル3と給電コイル1の軸方向の相対的な位置を電磁結合位置に設定するために受電部4を支える部材であって、その長さは基体40の略半分に近い適当な長さに設定されている。   Further, the upper end of the base body 40 enclosing the power receiving circuit 15 is configured as a flange portion 41 having a larger diameter than the main body portion enclosing the power receiving coil 3 and projecting outward. Is provided with a support portion 42 that protrudes toward the lower end side of the base body 40. The support portion 42 is rod-shaped, and is a member that supports the power receiving portion 4 in order to set the relative position in the axial direction of the power receiving coil 3 and the power feeding coil 1 to the electromagnetic coupling position. It is set to an appropriate length close to about half.

以上のような給電部2と受電部4の形状・構造によれば、受電部4は給電部2の貫通孔21に挿入して軸方向に移動可能であり、図3に示すように受電部4の基体40の上端部を給電部2の貫通孔21から上方に引き出して突出させた状態とし、支持部42を取り付け部30の上面に当接させれば、受電部4の受電コイル3がちょうど給電部2の給電コイル1と相対して電磁結合する位置(動作位置)に設定されて同位置に保持されることとなる。   According to the shape and structure of the power feeding unit 2 and the power receiving unit 4 as described above, the power receiving unit 4 can be inserted into the through-hole 21 of the power feeding unit 2 and moved in the axial direction, as shown in FIG. When the upper end portion of the base body 40 is drawn upward from the through-hole 21 of the power feeding portion 2 and protruded, and the support portion 42 is brought into contact with the upper surface of the mounting portion 30, the power receiving coil 3 of the power receiving portion 4 is The position (operating position) that is just electromagnetically coupled to the power feeding coil 1 of the power feeding section 2 is set and held at the same position.

また、図4に示すように支持部42を取り付け部30の上面から外して取り付け部30の開口31内に移動させ、受電部4を給電部2の貫通孔21内で下方に移動させて受電部4の基体40の下端部が給電部2の貫通孔21から下方に突出した状態にすれば、受電部4の基体40のフランジ部41が給電部2の上端に引っ掛かり、両部2、4は互いにコイル1,3が電磁結合から解除される非給電位置に設定されて同位置に保持されることとなる。   Further, as shown in FIG. 4, the support portion 42 is removed from the upper surface of the attachment portion 30 and moved into the opening 31 of the attachment portion 30, and the power reception portion 4 is moved downward in the through hole 21 of the power supply portion 2 to receive power. If the lower end portion of the base body 40 of the portion 4 protrudes downward from the through hole 21 of the power feeding portion 2, the flange portion 41 of the base body 40 of the power receiving portion 4 is caught by the upper end of the power feeding portion 2, and both portions 2, 4 Are set at a non-feeding position where the coils 1 and 3 are released from electromagnetic coupling with each other and held at the same position.

以上のように、給電部2(給電コイル1)と受電部4(受電コイル3)は互いに摺動可能で動作位置と収納位置との間で選択可能に位置設定できるので、図4に示すように受電部4が取り付け部30の開口31を塞いだ収納位置においては両コイル1,3の電磁結合は生じず、給電は行われない。また、図3に示すように受電部4が引き上げられて取り付け部30の開口31から上方に突出した動作位置においては両コイル1,3は電磁結合し、非接触の給電を行い得る給電状態になる。   As described above, the power feeding unit 2 (power feeding coil 1) and the power receiving unit 4 (power receiving coil 3) are slidable with respect to each other and can be set so as to be selectable between the operation position and the storage position, as shown in FIG. In the storage position where the power receiving unit 4 closes the opening 31 of the mounting unit 30, electromagnetic coupling between the coils 1 and 3 does not occur, and power feeding is not performed. In addition, as shown in FIG. 3, at the operating position where the power receiving unit 4 is pulled up and protrudes upward from the opening 31 of the mounting unit 30, the coils 1 and 3 are electromagnetically coupled to a power supply state capable of performing non-contact power supply. Become.

本例では、上述したように互いに摺動可能であって、収納位置と動作位置とに選択的に設定可能な2つのコイルの機械的構造において、さらに以下に示す駆動方法により、受電部4が収納位置にある場合には給電コイル1に流れる電流の電流値に基づいて受電部4が動作位置に設定されたことを検知し、受電部4が動作位置にある場合には給電コイル1が自動的に駆動されるようにしたものである。以下、本給電装置の回路構成によるかかる作用について説明する。   In this example, as described above, in the mechanical structure of the two coils that are slidable with each other and can be selectively set in the storage position and the operation position, the power receiving unit 4 is further driven by the following driving method. When the power receiving unit 4 is in the operating position, the power receiving unit 4 detects that the power receiving unit 4 is set to the operating position based on the current value of the current flowing through the power feeding coil 1. It is intended to be driven. Hereinafter, the operation of the power supply apparatus according to the circuit configuration will be described.

(2)本給電装置の作用(図5、図6)
本給電装置の作用を、制御手段10の動作を中心として説明する。
本給電装置では、以下に説明するように予め制御回路14に幾つかの基準値A1〜A3を設定しておき、給電コイル1に流れる電流の電流値を電流検出素子9で測定してこれら基準値A1〜A3と比較し、その比較結果に基づいて受電コイル3の有無や負荷20の軽重等の状態判断を行う。
(2) Operation of the power feeding device (FIGS. 5 and 6)
The operation of the power supply apparatus will be described focusing on the operation of the control means 10.
In this power feeding device, as will be described below, several reference values A1 to A3 are set in the control circuit 14 in advance, and the current value of the current flowing in the power feeding coil 1 is measured by the current detection element 9, and these standards are set. Compared with the values A1 to A3, the presence / absence of the power receiving coil 3 and the state of the load 20 are determined based on the comparison result.

まず、第1の基準値であるレベルA1は、給電コイル1と受電コイル3が給電状態以外の状態(具体的には受電コイル3が給電コイル1から外れている状態)から給電状態(具体的には受電コイル3が給電コイル1に全長挿入された状態)となって電磁結合が成立したことを検知するための判断基準値であり、給電コイル1の電流値がこのレベルA1よりも大きい場合には電磁結合がなく(つまり受電コイル3は挿入されておらず)、給電コイル1の電流値がこのレベルA1よりも小さい場合には電磁結合が成立している(つまり受電コイル3が挿入されている)、と判断される。   First, the level A1 that is the first reference value is a power supply state (specifically, the power supply coil 1 and the power reception coil 3 are in a state other than the power supply state (specifically, the power reception coil 3 is disconnected from the power supply coil 1). Is a criterion value for detecting that the power receiving coil 3 is fully inserted into the power feeding coil 1 and electromagnetic coupling is established, and the current value of the power feeding coil 1 is larger than this level A1. Has no electromagnetic coupling (that is, the receiving coil 3 is not inserted), and the electromagnetic coupling is established (that is, the receiving coil 3 is inserted) when the current value of the feeding coil 1 is smaller than the level A1. Is determined).

また、第2の基準値であるレベルA3は、給電コイル1と受電コイル3が給電状態(具体的には受電コイル3が給電コイル1に全長挿入されて電磁結合が成立した状態)から給電状態以外の状態(具体的には受電コイル3が給電コイル1から外れている状態)になったことを検知するための判断基準値であり、給電コイル1の電流値がこのレベルA3よりも大きい場合には給電コイル1に挿入されていた受電コイル3が抜き取られたものと判断される。   In addition, the level A3 that is the second reference value is the power supply state from the state where the power supply coil 1 and the power reception coil 3 are in a power supply state (specifically, the state where the power reception coil 3 is fully inserted into the power supply coil 1 and electromagnetic coupling is established). When the current value of the feeding coil 1 is larger than this level A3, it is a judgment reference value for detecting that it is in a state other than (specifically, the state where the receiving coil 3 is detached from the feeding coil 1). It is determined that the power receiving coil 3 inserted in the power feeding coil 1 has been removed.

また、第3の基準値であるレベルA2は、給電コイル1と受電コイル3が給電状態(具体的には受電コイル3が給電コイル1に全長挿入されて電磁結合が成立した状態)にあることを前提とし、その場合に負荷20が高負荷か軽負荷かを判断するための基準値であって、給電コイル1に流れる電流がレベルA2を越える場合には、相対的に小抵抗値の高負荷であると判断し、給電コイル1に与える駆動信号の周波数を相対的に低い周波数(16kHz)の駆動信号で駆動する。また、給電コイル1に流れる電流がレベルA2を下回る場合には、相対的に高抵抗値の軽負荷であると判断し、給電コイル1に与える駆動信号の周波数を相対的に高い周波数(32kHz)の駆動信号で駆動する。   Further, the level A2, which is the third reference value, is that the feeding coil 1 and the receiving coil 3 are in a feeding state (specifically, the receiving coil 3 is fully inserted into the feeding coil 1 and electromagnetic coupling is established). Is a reference value for determining whether the load 20 is a high load or a light load, and when the current flowing through the feeding coil 1 exceeds the level A2, the resistance value is relatively small. It is determined that it is a load, and the drive signal applied to the feeding coil 1 is driven with a drive signal having a relatively low frequency (16 kHz). When the current flowing through the feeding coil 1 is lower than the level A2, it is determined that the load is a relatively high resistance light load, and the frequency of the drive signal applied to the feeding coil 1 is set to a relatively high frequency (32 kHz). It drives with the drive signal.

以下、本給電装置の作動についてさらに具体的に説明する。以下の説明では、図4の流れ図に示す各動作ステップS1〜S9を用いて本装置の動作を適宜区切って説明し、各区切り毎に半括弧付き数字1)〜9)を参照符号として付した。また図5に示す電流波形にも対応して同一の半括弧付き数字1)〜9)を付し、理解の便宜とした。   Hereinafter, the operation of the power feeding apparatus will be described more specifically. In the following description, the operation of the apparatus is described by using the operation steps S1 to S9 shown in the flowchart of FIG. 4 as appropriate, and numerals 1) to 9) with parentheses are assigned as reference numerals for each partition. . In addition, the same numbers in parentheses 1) to 9) are attached to the current waveforms shown in FIG. 5 for convenience of understanding.

1)受電部4が挿入されていない状態では、32kHzで給電コイル1を駆動すると、第1の基準値であるレベルA1より大きい電流が流れるため、S1−S2−S3−S4−S5−S1のルートで動作する。制御手段10のタイマーで指定された時間ごとにS1信号はHとなり、受電コイル3の検出動作を繰り返す。   1) In a state where the power receiving unit 4 is not inserted, if the feeding coil 1 is driven at 32 kHz, a current greater than the first reference value level A1 flows, so that S1-S2-S3-S4-S5-S1 Works with root. The S1 signal becomes H every time specified by the timer of the control means 10, and the detection operation of the power receiving coil 3 is repeated.

2)受電部4が挿入されると32kHzで給電コイル1を駆動した時の電流がA1レベル未満となり、軽負荷と判断され、S1−S2−S3−S6のルートで動作し、S1信号はHのまま保たれるため駆動動作が連続する。この時電流がA1レベル以下の場合はS6−S8−S9−S6の動作を繰り返す。(軽負荷動作)   2) When the power receiving unit 4 is inserted, the current when the feeding coil 1 is driven at 32 kHz becomes less than the A1 level, it is determined that the load is light, and the operation is performed in the route of S1-S2-S3-S6. Since it is kept as it is, the driving operation continues. At this time, if the current is lower than the A1 level, the operations of S6-S8-S9-S6 are repeated. (Light load operation)

3)この後、受電部4を抜き取ると電流がA3レベルを超えるため、S6−S7−S9−S4−S5−S1のルートで動作を行い、受電コイル3の検出動作を繰り返す。   3) After that, when the power receiving unit 4 is extracted, the current exceeds the A3 level. Therefore, the operation is performed along the route S6-S7-S9-S4-S5-S1, and the detection operation of the power receiving coil 3 is repeated.

4)受電部4が挿入されると32kHzで給電コイル1を駆動した時の電流がA1レベル以下となり、S1−S2−S3−S6のルートで駆動動作が連続する。この時電流がA2レベルより大きい場合は、高負荷と判断され、S6−S7と動作し、S0出力を16kHzに変更し、S9−S6−S7−S9の動作を繰り返す。(高負荷動作)   4) When the power receiving unit 4 is inserted, the current when the feeding coil 1 is driven at 32 kHz becomes equal to or lower than the A1 level, and the driving operation is continued along the route of S1-S2-S3-S6. If the current is greater than the A2 level at this time, it is determined that the load is high, and the operation is performed as S6-S7, the S0 output is changed to 16 kHz, and the operations of S9-S6-S7-S9 are repeated. (High load operation)

5)この後、受電部4を抜き取ると電流がA3レベルを超えるため、S6−S7−S9−S4−S5−S1のルートで動作を行い、S0出力を32kHzとし受電コイル3の検出動作を繰り返す。   5) After that, if the power receiving unit 4 is extracted, the current exceeds the A3 level. Therefore, the operation is performed in the route of S6-S7-S9-S4-S5-S1, the S0 output is set to 32 kHz, and the detection operation of the power receiving coil 3 is repeated. .

6)受電部4が挿入された状態で負荷20が変動して電流が変化すると、電流がA2レベル以下の場合はS6−S8−S9−S6のルートで動作を繰り返す。   6) When the load 20 fluctuates and the current changes with the power receiving unit 4 inserted, the operation is repeated along the route of S6-S8-S9-S6 when the current is below the A2 level.

7)負荷20が変化してA2レベルより大きな電流が流れるとS6−S7−S9−S6のルートで動作を繰り返し、給電コイル1は16kHzで駆動される。   7) When the load 20 changes and a current larger than the A2 level flows, the operation is repeated along the route of S6-S7-S9-S6, and the feeding coil 1 is driven at 16 kHz.

8)電流が変化して電流がA2レベル以下になるとS6−S8−S9−S6のルートで動作を繰り返し、給電コイル1は32kHzで駆動される。   8) When the current changes and becomes lower than the A2 level, the operation is repeated through the route of S6-S8-S9-S6, and the feeding coil 1 is driven at 32 kHz.

9)もしA1レベルと受電部4が挿入されていない状態の電流値とが近いために、受電コイル3が給電コイル1に挿入されていないのに挿入されたものと誤検出してしまったとしても、S1−S2−S3−S6−S7−S9のルートで動作し、A1レベルより十分に大きいA3レベルとの大きな差を確実に検出してS9−S4−S5−S1のルートで動作を行い、検出動作を繰り返すことができる。   9) If the A1 level is close to the current value when the power receiving unit 4 is not inserted, it is erroneously detected that the power receiving coil 3 is inserted even though it is not inserted into the power feeding coil 1. Operates on the route of S1-S2-S3-S6-S7-S9, reliably detects a large difference from the A3 level sufficiently larger than the A1 level, and operates on the route of S9-S4-S5-S1. The detection operation can be repeated.

なお、以上説明した本例の給電装置の用途は多様であり、特に限定はしないが、防水性・防湿性が特に必要とされる環境下において、電気接続部分の着脱操作を頻繁に行うような用途(作業)で有効である。例えば、船釣りにおいてモータ駆動である電動リールを釣り竿に設けて使用する場合には、船の給電施設(電源)に接続した複数個の前記給電部を船縁(設置対象)の複数箇所に適当な配置で設けておき、釣り人(操作者)は電動リールのモータ(負荷)に前記受電部を接続しておき、必要に応じて甲板上を移動しながら、適当な位置にある給電部選択して自己の電動リールの受電部を差し込めば、自己が選択した位置で電源の供給を受けて電動リールを駆動操作し、釣り(作業)をすることができる。   In addition, the application of the power supply apparatus of the present example described above is various and is not particularly limited. However, in an environment where waterproofness and moisture resistance are particularly required, the electrical connection part is frequently attached and detached. Effective for use (work). For example, when an electric reel driven by a motor is provided on a fishing rod and used in boat fishing, a plurality of the power feeding parts connected to a power feeding facility (power source) of the ship are suitable for a plurality of locations on a ship edge (installation target). The angler (operator) connects the power receiving unit to the motor (load) of the electric reel and selects the power feeding unit at an appropriate position while moving on the deck as necessary. If the power receiving unit of the own electric reel is inserted, power can be supplied at the position selected by the self and the electric reel can be driven to perform fishing (work).

図7に示すように、給電部52は、内径が一定である横断面円形の貫通孔21が中心にある中空円筒形の給電コイル1を有している。給電コイル1は、その他の給電部回路(前記制御手段10、定電圧回路8、電流検出素子9等)とともに外装材料22によって一体に封着された密閉構造となって全体として円筒形の給電部52を構成しており、コイルや回路等の電気的構成部分は種々の環境に耐えうる防水性・防湿性・防塵性を備えている。なお電源7は外部から供給される。   As shown in FIG. 7, the power feeding unit 52 includes a hollow cylindrical power feeding coil 1 having a circular through hole 21 having a constant inner diameter and a circular cross section at the center. The power supply coil 1 has a sealed structure integrally sealed with an exterior material 22 together with other power supply circuit (the control unit 10, the constant voltage circuit 8, the current detection element 9 and the like), and has a cylindrical power supply as a whole. 52, and electrical components such as coils and circuits have waterproof, moistureproof, and dustproof properties that can withstand various environments.

そして、このような構造の給電部52は、貫通孔21が上下方向に貫通するような姿勢で取り付け部30の開口31の内側に縦に設置されており、給電コイル1の貫通孔21の上端の開口が、取り付け部30の開口31内の中央に配置されるように構成されている。   And the electric power feeding part 52 of such a structure is installed vertically inside the opening 31 of the attachment part 30 with the attitude | position which the through-hole 21 penetrates to an up-down direction, and the upper end of the through-hole 21 of the electric power feeding coil 1 Is configured to be disposed at the center in the opening 31 of the mounting portion 30.

受電部54は、給電部52の貫通孔21の軸線方向の長さの略2倍強の長さを有し、外装材料22と同様の材質からなる中実円柱状の基体56を備えている。そして、受電コイル3は、給電コイル1と同等の軸方向長さを有する磁性体(フェライト)23と、これの略全長に亘って巻かれた被覆導電線24とからなり、前記基体56の下端側(下半部)に封入されている。また、円柱状の基体56中の給電コイル1の上方には、整流回路(受電回路)15が封入されて受電コイル3に接続されており、さらに基体56内に封入された接続線を介して基体56の上端側面から封着状態で導出されて外部の出力コード60に接続され、負荷70(例えば照明装置)に接続されている。   The power receiving unit 54 has a solid cylindrical base 56 made of the same material as the exterior material 22, having a length approximately twice as long as the axial length of the through hole 21 of the power supply unit 52. . The power receiving coil 3 includes a magnetic body (ferrite) 23 having an axial length equivalent to that of the power feeding coil 1 and a covered conductive wire 24 wound over substantially the entire length thereof. It is enclosed on the side (lower half). Further, a rectifier circuit (power receiving circuit) 15 is sealed and connected to the power receiving coil 3 above the power feeding coil 1 in the cylindrical base 56, and further connected via a connection line sealed in the base 56. It is derived from the upper end side surface of the base body 56 in a sealed state, connected to an external output cord 60, and connected to a load 70 (for example, a lighting device).

また、受電部54の基体56の上端は、受電コイル3が封入された本体部分よりも大径で外方に張り出したフランジ部57とされている。また、基体56の周面において、フランジ部57の直下位置にあたる部分と、内部に封入された受電コイル3の上端に対応する位置にあたる部分には、給電部52の固定手段55に係合する周状の溝である上係合部58及び下係合部59がそれぞれ形成されており、受電部54を所定位置で係止・位置決めできるように構成されている。   Further, the upper end of the base 56 of the power receiving unit 54 is a flange portion 57 that has a larger diameter than the main body portion in which the power receiving coil 3 is enclosed and projects outward. Further, on the peripheral surface of the base body 56, a portion corresponding to the position immediately below the flange portion 57 and a portion corresponding to the upper end of the power receiving coil 3 enclosed inside are peripherally engaged with the fixing means 55 of the power feeding portion 52. An upper engaging portion 58 and a lower engaging portion 59 that are shaped grooves are formed, respectively, so that the power receiving portion 54 can be locked and positioned at a predetermined position.

前記負荷70は、取り付け部30の開口31に着脱自在な形状であり、例えば開口31が円形であれば負荷70は円筒形であり、開口31が矩形であれば負荷70は角筒状である。負荷70の下面側には空洞部71が開口しており、空洞部71の上底面には凸部72が下向きで設けられている。この凸部72は、負荷70を取り付け部30の開口31に収納した際に、受電部54のフランジ部57を下方に押圧して受電部54を給電部52の貫通孔21内に押し込むようになっている。また、負荷70は、空洞部71内で出力コード60に接続され、受電コイル3から電気の供給を受けるようになっている。   The load 70 has a shape that can be freely attached to and detached from the opening 31 of the mounting portion 30. For example, if the opening 31 is circular, the load 70 is cylindrical, and if the opening 31 is rectangular, the load 70 is rectangular. . A cavity portion 71 is opened on the lower surface side of the load 70, and a convex portion 72 is provided downward on the upper bottom surface of the cavity portion 71. The convex portion 72 presses the flange portion 57 of the power receiving portion 54 downward and pushes the power receiving portion 54 into the through hole 21 of the power feeding portion 52 when the load 70 is stored in the opening 31 of the attachment portion 30. It has become. Further, the load 70 is connected to the output cord 60 in the hollow portion 71 and is supplied with electricity from the power receiving coil 3.

出力コード60は伸縮自在な螺旋状の導電長体、所謂スパイラルケーブルであり、負荷70を開口31に収納した場合には凸部72の周囲に外挿されて整頓された状態で空洞部71内に収納され、負荷70を開口31から取り外して移動した場合には伸張して適当な張力で受電部54に引き上げ力を与えることができるようになっている。   The output cord 60 is a so-called spiral cable that can expand and contract, and when the load 70 is accommodated in the opening 31, the output cord 60 is extrapolated around the convex portion 72 and arranged in a tidy state. When the load 70 is removed from the opening 31 and moved, the load 70 can be stretched and applied to the power receiving unit 54 with an appropriate tension.

以上のような給電部52と受電部54の形状・構造によれば、受電部54は給電部52の貫通孔21に挿入して軸方向に移動可能であり、人力で移動させた場合には動作位置と収納位置とのいずれかに所定のクリック感を以て係止し、所定の係止力で位置決めされる。   According to the shape and structure of the power feeding unit 52 and the power receiving unit 54 as described above, the power receiving unit 54 can be inserted into the through-hole 21 of the power feeding unit 52 and moved in the axial direction. It is locked with a predetermined click feeling at either the operating position or the storage position, and is positioned with a predetermined locking force.

そして、図7に示すように取り付け部30の開口31から負荷70を取り出して使用位置に移動させると、受電部54は出力コード60に引っ張られて持ち上がり、下係合部59が固定手段55に係合することにより、受電部54の基体56の上端部側が給電部52の貫通孔21から上方に突出する動作位置に設定・保持されて両コイル1,3は電磁結合し、給電状態となる。   Then, when the load 70 is taken out from the opening 31 of the attachment portion 30 and moved to the use position as shown in FIG. 7, the power receiving portion 54 is pulled up by the output cord 60 and lifted, and the lower engagement portion 59 is moved to the fixing means 55. By engaging, the upper end side of the base 56 of the power receiving unit 54 is set and held at the operating position protruding upward from the through hole 21 of the power feeding unit 52, and both the coils 1 and 3 are electromagnetically coupled to enter a power feeding state. .

また、図8に示すように負荷70を開口31に戻せば、負荷70の凸部72が受電部54のフランジ部57を押し下げ、上係合部58が固定手段55に係合することにより、受電部54は受電コイル3がある基体56の下半部が給電部52の貫通孔21から下方に突出する収納位置に設定・保持されて両コイル1,3の電磁結合は解除され、非給電状態となる。   Further, when the load 70 is returned to the opening 31 as shown in FIG. 8, the convex portion 72 of the load 70 pushes down the flange portion 57 of the power receiving portion 54, and the upper engagement portion 58 engages with the fixing means 55. The power receiving unit 54 is set and held in a storage position in which the lower half of the base body 56 with the power receiving coil 3 protrudes downward from the through hole 21 of the power feeding unit 52, so that the electromagnetic coupling between the coils 1 and 3 is released, and no power is fed. It becomes a state.

本例の用途例としては、負荷70をライトとし、照明装置を開口31から取り外してある程度引っ張ると給電状態になって光が照射されるようにした照明装置が一例として考えられる。   As an application example of this example, an illumination device in which the load 70 is a light and the illumination device is removed from the opening 31 and pulled to some extent and is in a power supply state so that light is emitted can be considered as an example.
