Description

本発明は、電力伝送装置に係り、特に、１次コイルと、前記１次コイルに供給される電力に応じた電力が誘導される２次コイルと、前記１次コイル及び前記２次コイルが互いに同軸上に配置されるように螺旋状に巻回される支持物と、が備えられた電力伝送装置に関するものである。   The present invention relates to a power transmission device, and in particular, a primary coil, a secondary coil that induces power according to the power supplied to the primary coil, and the primary coil and the secondary coil are mutually connected. The present invention relates to a power transmission device including a support wound spirally so as to be disposed on the same axis.

従来、上述した電力伝送装置は、フェライト、鉄心又は空心などの支持物に対して上記１次コイル及び２次コイルを必要ターン数巻き付けて構成されている。上記１次コイルに電力を供給すると、１次コイルと２次コイルとのターン数比に応じた電力が２次コイルに誘導され、１次コイルから２次コイルに対して電力が伝送される。   Conventionally, the above-described power transmission device is configured by winding the primary coil and the secondary coil on a support such as a ferrite, an iron core, or an air core by the required number of turns. When power is supplied to the primary coil, power corresponding to the turn ratio between the primary coil and the secondary coil is induced in the secondary coil, and power is transmitted from the primary coil to the secondary coil.

ところで、従来では、２次コイル側に伝送する電力を変更するときは、１次コイル又は２次コイルのターン数を変更して対応していた。しかしながら、１次、２次コイルの作成後に１次、２次コイルのターン数は容易に変更することができない。このため、電力伝送装置を回路上に組み付け後に２次コイル側に伝送する電力を変更したいときは、電力伝送装置を作成し直さなくてはならず、容易に電力変更することができない、という問題があった。また、上述した変更に際しては回路上に組み付けた電力伝送装置を取り除いて１次、２次コイルのターン数を変更した電力伝送装置を回路に組み付け直す必要があるため装置の信頼性も低下する結果になっていた。   By the way, conventionally, when the electric power transmitted to the secondary coil side is changed, the number of turns of the primary coil or the secondary coil is changed. However, the number of turns of the primary and secondary coils cannot be easily changed after the primary and secondary coils are created. For this reason, when it is desired to change the power transmitted to the secondary coil side after the power transmission device is assembled on the circuit, the power transmission device must be recreated, and the power cannot be easily changed. was there. In addition, when the above-described change is made, it is necessary to remove the power transmission device assembled on the circuit and reassemble the power transmission device in which the number of turns of the primary and secondary coils is changed, so that the reliability of the device also decreases. It was.

また、１次コイルに供給する電力を変更して２次コイル側に伝送する電力を変更するものも提案されている（特許文献１〜３）。しかしながら、この場合は１次コイルに供給する電力が変えられない場合は適用することができない、という問題があった。

そこで、本発明は、信頼性を維持した状態で電力を容易に変更することができる電力伝送装置を提供することを課題とする。   Then, this invention makes it a subject to provide the electric power transmission apparatus which can change electric power easily in the state which maintained reliability.

上記課題を解決するためになされた請求項１記載の発明は、１次コイルと、前記１次コイルに供給される電力に応じた電力が誘導される２次コイルと、前記１次コイル及び前記２次コイルが互いに同軸上に配置された状態で螺旋状に巻回される１つの支持物と、が備えられた電力伝送装置において、前記支持物の前記１次コイル及び前記２次コイルの軸周りに螺旋状溝が設けられ、前記１次コイル及び前記２次コイルの少なくとも一方が、前記螺旋状溝内に収容されるように巻回され、前記一方のコイルを前記支持物の回りに回転させることにより、前記一方のコイルを前記螺旋状溝に沿って移動させ、他方のコイルとの相対位置を調整することができることを特徴とする電力伝送装置に存する。 The invention according to claim 1, which has been made in order to solve the above-described problem, includes a primary coil, a secondary coil that induces electric power according to electric power supplied to the primary coil, the primary coil, and the primary coil. And a support that is spirally wound in a state in which the secondary coils are coaxially arranged with each other, in the power transmission device, the shaft of the primary coil and the secondary coil of the support A spiral groove is provided around, and at least one of the primary coil and the secondary coil is wound so as to be accommodated in the spiral groove, and the one coil is rotated around the support. Thus, the present invention resides in a power transmission device characterized in that the one coil can be moved along the spiral groove and the relative position with the other coil can be adjusted .

請求項２記載の発明は、前記支持物が、リング状に設けられ、前記１次コイル及び前記２次コイルが、前記支持物にトロイダル状に巻回されていることを特徴とする請求項１に記載の電力伝送装置に存する。   The invention according to claim 2 is characterized in that the support is provided in a ring shape, and the primary coil and the secondary coil are wound around the support in a toroidal shape. It exists in the electric power transmission apparatus as described in.

以上説明したように請求項１及び２記載の発明によれば、１次、２次コイルを回転させると、螺旋状溝に沿って支持物上の１次、２次コイルが軸方向に沿って移動する。よって、１次コイル、２次コイルを支持物に巻回したまま１次コイルと２次コイルとの軸方向の相対位置を調整して、１次コイルと２次コイルとの結合度を調整することができる。このため、電力伝送装置を回路に組み付けたまま簡単に電力を変更することができ、信頼性を維持した状態で電力を容易に変更することができる。   As described above, according to the first and second aspects of the invention, when the primary and secondary coils are rotated, the primary and secondary coils on the support are moved along the axial direction along the spiral groove. Moving. Therefore, the relative position of the primary coil and the secondary coil in the axial direction is adjusted while the primary coil and the secondary coil are wound around the support, thereby adjusting the degree of coupling between the primary coil and the secondary coil. be able to. For this reason, it is possible to easily change the power while the power transmission device is assembled in the circuit, and it is possible to easily change the power while maintaining reliability.

以下、本発明の実施の形態を図面に基づいて説明する。図１に示すように、電力伝送装置１は、１次コイルＣ１と、２次コイルＣ２と、支持物としての樹脂支持物２と、を備えている。１次コイルＣ１は、螺旋状に巻かれた導線から構成されている。１次コイルＣ１の両端は、図示しない高周波電力源に接続されていて、１次コイルＣ１には高周波電力が供給される。２次コイルＣ２は、螺旋状に巻かれた導線から構成されている。２次コイルＣ２は、１次コイルＣ１に供給される電力に応じた電力が誘導される。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, the power transmission device 1 includes a primary coil C1, a secondary coil C2, and a resin support 2 as a support. The primary coil C1 is comprised from the conducting wire wound helically. Both ends of the primary coil C1 are connected to a high-frequency power source (not shown), and high-frequency power is supplied to the primary coil C1. The secondary coil C2 is composed of a conductive wire wound in a spiral shape. Power corresponding to the power supplied to the primary coil C1 is induced in the secondary coil C2.

樹脂支持物２は、上記１次コイルＣ１及び２次コイルＣ２が螺旋状に巻回されて固定される。樹脂支持物２には、１次コイルＣ１及び２次コイルＣ２が軸Ｚ方向に互いに離間して巻回されている。樹脂支持物２は、中央に貫通穴２１が設けられたリング状に形成されている。よって、樹脂支持物２には、１次コイルＣ１及び２次コイルＣ２が貫通穴２１を中心として円状の軸Ｚに沿って螺旋状に巻回されている。即ち、樹脂支持物２には、１次コイルＣ１及び２次コイルＣ２がトロイダル状に巻回されている。   The resin support 2 is fixed by winding the primary coil C1 and the secondary coil C2 spirally. A primary coil C1 and a secondary coil C2 are wound around the resin support 2 apart from each other in the axis Z direction. The resin support 2 is formed in a ring shape in which a through hole 21 is provided in the center. Therefore, the primary coil C <b> 1 and the secondary coil C <b> 2 are spirally wound around the resin support 2 along the circular axis Z around the through hole 21. That is, the primary coil C1 and the secondary coil C2 are wound around the resin support 2 in a toroidal shape.

また、樹脂支持物２には、貫通穴２１と同じ貫通方向に端子穴２２が設けられている。１次コイルＣ１及び２次コイルＣ２の両端は、貫通方向の一方側から端子穴２２に挿入されて他方側に引き出されている。   The resin support 2 is provided with terminal holes 22 in the same penetration direction as the through holes 21. Both ends of the primary coil C1 and the secondary coil C2 are inserted into the terminal hole 22 from one side in the penetrating direction and pulled out to the other side.

上記樹脂支持物２には、図２に示すように、１次コイルＣ１及び２次コイルＣ２の軸Ｚ周りに螺旋状溝２３が設けられている。１次コイルＣ１及び２次コイルＣ２は、この螺旋状溝２３内に収容されるように巻回されている。２次コイルＣ２が収容される螺旋状溝２３の軸Ｚ方向の長さＬ１は、２次コイルＣ２の軸Ｚ方向の長さＬ２よりも長くなるように形成されている。   As shown in FIG. 2, the resin support 2 is provided with a spiral groove 23 around the axis Z of the primary coil C1 and the secondary coil C2. The primary coil C1 and the secondary coil C2 are wound so as to be accommodated in the spiral groove 23. The length L1 in the axis Z direction of the spiral groove 23 in which the secondary coil C2 is accommodated is formed to be longer than the length L2 in the axis Z direction of the secondary coil C2.

以上の構成によれば、２次コイルＣ２を軸Ｚ周りに回転させると、螺旋状溝２３に沿って支持物２上の２次コイルＣ２が軸Ｚ方向に沿って移動する。次に、２次コイルＣ２側に伝送する電力を変更したい場合の手順について説明する。まず、樹脂支持物２の端子穴２２から２次コイルＣ２の両端を抜く。その後、２次コイルＣ２を軸Ｚ周りに回転させて、１次コイルＣ１と２次コイルＣ２との軸Ｚ方向の相対位置を調整する。これにより、１次コイルＣ１と２次コイルＣ２との結合度を調整して、電力を変更する。次に、再び２次コイルＣ２の両端を端子穴２２に挿入する。   According to the above configuration, when the secondary coil C2 is rotated around the axis Z, the secondary coil C2 on the support 2 moves along the axis Z direction along the spiral groove 23. Next, a procedure for changing the power transmitted to the secondary coil C2 side will be described. First, the both ends of the secondary coil C2 are extracted from the terminal hole 22 of the resin support 2. Thereafter, the secondary coil C2 is rotated around the axis Z, and the relative position in the axis Z direction between the primary coil C1 and the secondary coil C2 is adjusted. Thereby, the electric power is changed by adjusting the degree of coupling between the primary coil C1 and the secondary coil C2. Next, both ends of the secondary coil C2 are inserted into the terminal holes 22 again.

上述した電力伝送装置１によれば、２次コイルＣ１を樹脂支持物２に巻回したまま１次コイルＣ１と２次コイルＣ２との軸Ｚ方向の相対位置を調整して、１次コイルＣ１と２次コイルＣ２との結合度を調整することができる。このため、電力伝送装置１を回路に組み付けたまま簡単に電力を変更することができ、信頼性を維持した状態で電力を容易に変更することができる。   According to the power transmission device 1 described above, the primary coil C1 is adjusted by adjusting the relative position in the axis Z direction between the primary coil C1 and the secondary coil C2 while the secondary coil C1 is wound around the resin support 2. And the degree of coupling between the secondary coil C2 can be adjusted. For this reason, it is possible to easily change the power while the power transmission device 1 is assembled in a circuit, and it is possible to easily change the power while maintaining reliability.

なお、上述した実施形態によれば、２次コイルＣ２のみを移動させていたが、本発明はこれに限ったものではない。１次コイルＣ１のみを移動させてもよいし、１次コイルＣ１及び２次コイルＣ２の両方を移動させるようにしてもよい。   According to the above-described embodiment, only the secondary coil C2 is moved, but the present invention is not limited to this. Only the primary coil C1 may be moved, or both the primary coil C1 and the secondary coil C2 may be moved.

また、上述した実施形態によれば、１次コイルＣ１及び２次コイルＣ２の両方が螺旋状溝２３内に収容されていたが、本発明はこれに限ったものではない。１次コイルＣ１及び２次コイルＣ２の少なくとも一方が螺旋状溝２３内に収容されていればよい。   Further, according to the embodiment described above, both the primary coil C1 and the secondary coil C2 are accommodated in the spiral groove 23, but the present invention is not limited to this. It is sufficient that at least one of the primary coil C1 and the secondary coil C2 is accommodated in the spiral groove 23.

また、前述した実施形態は本発明の代表的な形態を示したに過ぎず、本発明は、実施形態に限定されるものではない。即ち、本発明の骨子を逸脱しない範囲で種々変形して実施することができる。   Further, the above-described embodiments are merely representative forms of the present invention, and the present invention is not limited to the embodiments. That is, various modifications can be made without departing from the scope of the present invention.
