スイッチング電源はスイッチング効率を向上させる目的からスイッチング周波 数に数十KHzから数百KHzの高周波数が適用されるようになってきた。 しかし ながら上記のような高周波帯域になると変圧器巻線の導体内の渦電流損及び表皮 効果による損失が顕著になり、変圧器の発熱量の増大を招き、巻線用絶縁電線は もとより変圧器の特性を劣化させる恐れが生じてきた。 Switching power supplies have a switching frequency for the purpose of improving switching efficiency. High frequencies from several tens of KHz to several hundred KHz have come to be applied to many applications. but However, in the high frequency band mentioned above, eddy current loss and skin damage in the conductor of the transformer winding occur. The loss due to this effect becomes noticeable, leading to an increase in the heat output of the transformer, and the insulated wire for the winding is There has also been a fear that the characteristics of the transformer may deteriorate.
【０００５】 本考案は上記問題点を解決するために為されたものであり、上記各種安全規格 を満足し、かつスイッチング周波数が高周波数帯域であっても変圧器の発熱量の 低減を図ることが可能な変圧器巻線用絶縁電線を提供することを目的とする。[0005] This invention was devised to solve the above problems, and it complies with the various safety standards mentioned above.

上記目的を達成するために本考案は、マグネットワイヤの複数本を集束した集 束導体の外周上に、耐熱性樹脂の押出層からなる絶縁層を少なくとも３層設け、 該３層のうちの何れか２層の絶縁層で規定の耐電圧特性を保持せしめるべく形成 すると共に、前記３層の絶縁層の各層はそれぞれ独立していて分離可能とした高 周波変圧器巻線用多層絶縁電線（以下多層絶縁電線と略記する）にある。 In order to achieve the above object, the present invention has developed a collection method that combines multiple magnet wires. At least three insulating layers made of extruded layers of heat-resistant resin are provided on the outer periphery of the bundle conductor, Any two of the three layers are formed to maintain specified withstand voltage characteristics. At the same time, each layer of the three insulating layers is independent and separable. Multilayer insulated wire for frequency transformer winding (hereinafter abbreviated as multilayer insulated wire).
【０００７】 本考案のマグネットワイヤとしては、銅線，銅合金線，或は錫又ははんだめっ き銅線等の単線導体上にポリウレタン樹脂，ポリエステル樹脂等の絶縁層を施し たものが用いられる。導体構成は変圧器の仕様により適宜に選択されるが、複数 本のマグネットワイヤからなる導体断面積で、主として０．０３２mm2（ＡＷＧ ３２）から０．５２mm2（ＡＷＧ２０）の範囲の導体が用いられる。本考案の集 束導体は、前記マグネットワイヤの複数本を略平行に断面円形状に集束したもの でも良いし、前記マグネットワイヤの複数本を集合撚り、同心撚り或はリッツ撚 り等の方法により撚り合わせて断面円形状に集束したものでも良い。[0007] The magnet wire of the present invention is a single wire conductor such as a copper wire, a copper alloy wire, or a tin- or solder-plated copper wire, on which an insulating layer of polyurethane resin, polyester resin, or the like is applied. The conductor configuration is selected as appropriate depending on the specifications of the transformer, but the cross-sectional area of the conductor consisting of multiple magnet wires is mainly used in the range of 0.032 mm 2 (AWG 32) to 0.52 mm 2 (AWG 20). It will be done. The focusing conductor of the present invention may be one in which a plurality of the above-mentioned magnet wires are focused in a substantially parallel manner to have a circular cross-section, or a plurality of the above-mentioned magnet wires may be twisted together by a method such as collective twisting, concentric twisting, litz twisting, etc. It may also be one that is focused in a circular cross-section.
【０００８】 多層絶縁電線の絶縁層としては、耐熱性樹脂，例えば各種ふっ素樹脂あるいは 種々のエンジニアリングプラスチック等を導体上に複数回重層して押出しした押 出層が用いられる。また、必要であれば、各絶縁層を明確に識別するために、各 絶縁層樹脂を異なる色相の樹脂を用いる等の方法によって各層を異なる色相に着 色して用いてもよい。[0008] The insulation layer of the multilayer insulated wire is made of heat-resistant resin, such as various fluororesins or An extruded product made by layering various engineering plastics multiple times on a conductor. Out layer is used. Also, if necessary, each insulating layer can be clearly identified. Each layer is colored a different color by using different colored resins for the insulating layer resin. May be used in different colors.
【０００９】 ３層の絶縁層の各層が独立していて分離可能であるとの意味は、各絶縁層が個 別に剥離可能であり、かつ独立した１層として存在するものを言う。絶縁層の剥 離手段としては、剥離器（ストリッパー）を用いる方法，絶縁層にスリット傷を 入れて除去する方法，或は絶縁層を熱刃で焼き切り除去する方法等がある。[0009] The meaning that each layer of the three insulating layers is independent and separable means that each insulating layer is independent. A layer that can be peeled off separately and exists as an independent layer. Peeling the insulation layer The removal method is to use a stripper, or to make slits in the insulation layer. There are two methods: inserting and removing the insulating layer, or burning off the insulating layer with a hot blade.
【００１０】 マグネットワイヤの皮膜は導体の外周に絶縁塗料を複数回塗布，焼付けして形 成されるが、全塗膜により単一層の絶縁層が形成され、層毎に分離することが不 可能であるため多層絶縁電線とは認められないものである。本考案においてもマ グネットワイヤを使用しているが、単線の状態で多層電線として用いようとして いるのではなく、集束導体を構成する絶縁された素線として用いているものであ る。0010 The film of the magnet wire is formed by applying insulating paint multiple times around the outer circumference of the conductor and baking it. However, the entire coating forms a single insulating layer, and it is difficult to separate each layer. Therefore, it cannot be recognized as a multilayer insulated wire. In this invention, I'm using net wire, but I'm trying to use it as a multilayer wire when it's a single wire. It is used as an insulated wire that makes up the focusing conductor. Ru.

本考案の集束導体は、マグネットワイヤの複数本を略平行にかつ断面円形状に 集束するか、またはマグネットワイヤの複数本を撚り合わせて断面円形状に集束 したものであり、マグネットワイヤの導体はそれぞれ絶縁されているため渦電流 の発生は低く押さえられるので、渦電流損に伴う高周波抵抗の増加を押さえるこ とが出来る。また集束導体は、単線の導体と比較すると導体表面積が大幅に増大 するため、表皮効果による損失の増大を著しく改善することが可能となる。また 、前記マグネットワイヤの複数本を略平行にかつ断面円形状に集束した場合、或 は前記マグネットワイヤの複数本を撚り合わせて断面円形状に集束する場合でも 撚りピッチを大きくした場合は使用導体の撚り込み長さを短くすることができ、 その分コイルの直流抵抗を減ずることが可能となる。 The focusing conductor of this invention consists of multiple magnet wires that are approximately parallel and have a circular cross section. or twist multiple strands of magnet wire together to form a circular cross-section. Since each conductor of the magnet wire is insulated, eddy current Since the occurrence of I can do that. Also, a focused conductor has a significantly increased conductor surface area compared to a single wire conductor. Therefore, it becomes possible to significantly improve the increase in loss due to the skin effect. Also , when a plurality of the magnet wires are bundled approximately in parallel and have a circular cross section, or Even when multiple magnet wires are twisted together and focused into a circular cross-section, When the twisting pitch is increased, the twisted length of the conductor used can be shortened. It becomes possible to reduce the direct current resistance of the coil accordingly.
