コア付き配線およびコア付き配線の製造方法Method of manufacturing cored wiring and cored wiring
　本発明は、配線に環状のコアを設けて電気的ノイズを抑制するコア付き配線およびコア付き配線の製造方法に関する。 The present invention relates to a cored wiring and a method of manufacturing the cored wiring by providing an annular core in the wiring to suppress electrical noise.
　電気的ノイズの発生源を有する機器では、各国の規制値または国際的に標準化されたＥＭＣ（Electromagnetic　Compatibility）規格を満足するために、電気的ノイズを抑制するための対策を講じる必要がある。たとえば、空気調和機では、ＤＣ（Direct　Current）／ＤＣ電源回路、コンバータ回路およびインバータ回路といった多くの電気的ノイズの発生源を有している。空気調和機から発生する電気的ノイズを抑制するための対策としては、電子プリント基板間、または電子プリント基板と各アクチュエータとの間を接続する配線にトロイダルコアを設けることが一般的である。 In equipment having a source of electrical noise, it is necessary to take measures to suppress electrical noise in order to satisfy the regulatory value of each country or the internationally standardized EMC (Electromagnetic Compatibility) standard. For example, air conditioners have many sources of electrical noise such as DC (Direct Current) / DC power supply circuits, converter circuits and inverter circuits. As a countermeasure for suppressing the electrical noise generated from the air conditioner, it is general to provide a toroidal core in the wiring connecting between the electronic printed boards or between the electronic printed boards and each actuator.
　特許文献１には、配線にトロイダルコアを固定する技術が開示されている。特許文献１には、リード挿通孔が設けられたトロイダルコアと、このトロイダルコアのリード挿通孔に挿通されるとともに、トロイダルコアの両端側から突出した部分にそれぞれ屈曲部が設けられた導電性のリードと、トロイダルコアを収容した第１の熱収縮絶縁チューブが熱収縮してなる第１の収縮後絶縁部材と、第１の収縮後絶縁部材で被覆されたトロイダルコアを収容した第２の熱収縮絶縁チューブが熱収縮してなる第２の収縮後絶縁部材とを備えたインダクタンス素子が開示されている。 Patent Document 1 discloses a technique for fixing a toroidal core to wiring. In Patent Document 1, a toroidal core provided with a lead insertion hole, and an electroconductive member inserted into the lead insertion hole of the toroidal core and provided with a bent portion at a portion protruding from both end sides of the toroidal core. A second heat-shrinkage member containing a lead, a first post-shrinkage insulation member formed by heat contraction of a first heat-shrinkage insulation tube containing a toroidal core, and a second heat-seal structure containing the first post-shrinkage insulation member. Disclosed is an inductance element including a second post-shrinkage insulation member in which the contraction insulation tube is thermally shrunk.

　しかしながら、上述した特許文献１に記載の技術では、リードに屈曲部を設けてトロイダルコアの位置を固定しているが、電子プリント基板間、または電子プリント基板と各アクチュエータとの間を接続する配線として一般的に使用される、たとえば被覆付きのより線で構成される３本の配線では、曲げたときの元に戻ろうとする力が強いため、屈曲部を成形することが困難である。すなわち、配線の構造および本数によっては、屈曲部を成形することが困難であるため、屈曲部を設けることができず、トロイダルコアを配線の任意の位置に固定することができない、という問題があった。さらに、上述した特許文献１に記載の技術では、リードに屈曲部を設けてトロイダルコアの位置を固定しているため、屈曲部の部分で配線が曲がることになり配線を直線的に設けることができない、という問題があった。 However, in the technology described in Patent Document 1 described above, the bent portion is provided in the lead to fix the position of the toroidal core, but the wiring for connecting between the electronic printed boards or between the electronic printed boards and each actuator In the case of three wires generally used as, for example, coated stranded wires, it is difficult to form a bent portion because the force to return to the original shape upon bending is strong. That is, depending on the structure and the number of wires, it is difficult to form the bent portion, so that the bent portion can not be provided, and there is a problem that the toroidal core can not be fixed at any position of the wire. The Furthermore, in the technique described in Patent Document 1 described above, since the bent portion is provided in the lead to fix the position of the toroidal core, the wire is bent at the bent portion and the wire is linearly provided. There was a problem that it was impossible.
　本発明は、上記に鑑みてなされたものであって、環状のコアを配線の任意の位置に固定することができるとともに、全体としてみて配線を直線的に設けることができるコア付き配線を得ることを目的とする。 The present invention has been made in view of the above, and it is an object of the present invention to provide a cored wiring in which an annular core can be fixed at an arbitrary position of the wiring and the wiring as a whole can be linearly provided. With the goal.
　上述した課題を解決し、目的を達成するために、本発明にかかる、コア付き配線は、挿通孔が形成された環状のコアを備える。コア付き配線は、挿通孔の一方の開口から他方の開口に向けて挿通され、他方の開口において、環状のコアの内周側から外周側へ折り返され、一方の開口において、外周側から内周側へ折り返され、一方の開口から他方の開口に向けて再度挿通された配線を備える。コア付き配線は、配線が挿通された環状のコアを収容した熱収縮チューブが熱収縮してなる熱収縮後部材を備える。 In order to solve the problems described above and achieve the object, the cored wiring according to the present invention includes an annular core in which an insertion hole is formed. The cored wiring is inserted from one opening of the insertion hole toward the other opening, and is folded back from the inner peripheral side to the outer peripheral side of the annular core in the other opening, and the inner peripheral side from the outer peripheral side in one opening It has the wiring folded back to the side and re-inserted from one opening to the other opening. The cored wiring includes a post-shrinkage member in which a heat-shrinkable tube containing an annular core into which the wiring is inserted is thermally shrunk.
　本発明にかかるコア付き配線は、環状のコアを配線の任意の位置に固定することができるとともに、全体としてみて配線を直線的に設けることができるという効果を奏する。 The cored wiring according to the present invention has an effect that the annular core can be fixed at an arbitrary position of the wiring and the wiring can be linearly provided as a whole.

Next, in the other opening 1 c, the wiring 2 is folded back from the inner periphery 1 d side of the toroidal core 1 to the outer periphery 1 e side. Then, the wiring 2 is extended along the outer periphery 1 e. Then, in one opening 1b, the wiring 2 is folded back from the outer periphery 1e side to the inner periphery 1d side. Then, the wiring 2 is again inserted from one opening 1 b toward the other opening 1 c.

　本実施の形態によれば、図２に示すように、熱収縮チューブ３が配線２をトロイダルコア１の外周１ｅに押さえ付ける。これにより、トロイダルコア１が配線２に固定される。図３に示すように、トロイダルコア１に配線２が巻き付いているが、配線２に対するトロイダルコア１の位置は配線２の折り返し位置を変更することにより任意に変更可能である。したがって、トロイダルコア１を配線２の任意の位置に固定することができる。さらに、配線２が、２ターンした、すなわち２回折り返した構成であるため、全体としてみて配線２を直線的に設けることができる。 According to the present embodiment, as shown in FIG. 2, the heat-shrinkable tube 3 presses the wire 2 against the outer periphery 1 e of the toroidal core 1. Thus, the toroidal core 1 is fixed to the wiring 2. As shown in FIG. 3, although the wiring 2 is wound around the toroidal core 1, the position of the toroidal core 1 with respect to the wiring 2 can be arbitrarily changed by changing the turn-back position of the wiring 2. Therefore, the toroidal core 1 can be fixed to an arbitrary position of the wiring 2. Furthermore, since the wiring 2 is configured to be turned twice, that is, folded back twice, the wiring 2 can be provided linearly as a whole.

The wiring 2 in the portion wound around the core 1 can be protected.
　本実施の形態によれば、トロイダルコア１の挿通孔１ａに配線２が挿通される前は、トロイダルコア１の内周１ｄ側は熱収縮チューブ３により覆われない。これにより、トロイダルコア１の挿通孔１ａに配線２が挿通される前にトロイダルコア１の内周１ｄ側も熱収縮チューブ３により覆われる場合と比較して、配線２が挿通される部分の直径が小さくなることがない。 According to the present embodiment, the heat-shrinkable tube 3 does not cover the inner periphery 1 d side of the toroidal core 1 before the wire 2 is inserted into the insertion hole 1 a of the toroidal core 1. Thereby, the diameter of the portion through which the wire 2 is inserted is compared with the case where the inner periphery 1d side of the toroidal core 1 is also covered with the heat-shrinkable tube 3 before the wire 2 is inserted into the insertion hole 1a of the toroidal core 1 Does not get smaller.
　本実施の形態では、図５に示すように、配線２が、さらに、トロイダルコア１の他方の開口１ｃにおいて、トロイダルコア１の内周１ｄ側から外周１ｅ側へ再度折り返され、外周１ｅに沿って再度伸ばされて、一方の開口１ｂにおいて、外周１ｅ側から内周１ｄ側へ再度折り返され、一方の開口１ｂから他方の開口１ｃに向けて三度挿通されていてもよい。すなわち、本実施の形態では、配線２が、２ターン以上、たとえば３ターンした構成のコア付き配線１００Ａであってもよい。ターン数は、配線２がトロイダルコア１の挿通孔１ａを通る回数である。 In the present embodiment, as shown in FIG. 5, in the other opening 1c of the toroidal core 1, the wiring 2 is further folded back from the inner periphery 1d side of the toroidal core 1 to the outer periphery 1e side along the outer periphery 1e.
