以下の図面を参照して、本発明の実施の形態に係る絶縁電線及び絶縁コイルを説明し、本発明の理解に供する。しかし、以下の説明は本発明の実施形態であって、特許請求の範囲に記載の内容を限定するものではない。 With reference to the following drawings, an insulated wire and an insulated coil according to an embodiment of the present invention will be described for understanding of the present invention. However, the following description is an embodiment of the present invention, and does not limit the contents described in the claims.
図１は本発明の実施形態に係る絶縁電線の断面図である。図２は図１の絶縁電線を巻回して得られた絶縁コイルの概略を示す断面図である。 FIG. 1 is a cross-sectional view of an insulated wire according to an embodiment of the present invention. FIG. 2 is a cross-sectional view showing an outline of an insulated coil obtained by winding the insulated wire of FIG.
先ず図１を参照して、本実施形態の絶縁電線１は、絶縁コイルに用いられる電線であり、導線２と、絶縁層３ａと、絶縁層３ｂとで構成されている。 First, referring to FIG. 1, an insulated wire 1 according to the present embodiment is an electric wire used for an insulated coil, and includes a conductive wire 2, an insulating layer 3 a, and an insulating layer 3 b.
前記導線２は、図１に示すように、断面円形の導線である。導線としては、例えば純銅や銅合金からなる導線、銀等他の金属材料からなる導線等があるが、公知の如何なる導線であってもよい。
また導線の断面形状も、四角、六角等如何なるものであってもよいし、その導径も用途に応じて適宜変更可能である。
The conducting wire 2 is a conducting wire having a circular cross section, as shown in FIG. Examples of the conductive wire include a conductive wire made of pure copper or a copper alloy, a conductive wire made of another metal material such as silver, and any known conductive wire.
Also, the cross-sectional shape of the conducting wire may be any shape such as a square or a hexagon, and the conducting diameter can be appropriately changed according to the application.
前記絶縁層３ａは、導線２の外周に被覆された非融着性の樹脂で構成される層である。このように非融着性の樹脂を用いることで、コストを抑えた絶縁電線１とすることが可能となる。また絶縁層３ａは、図１に示すように、導線２と同じ外周形状をしている。このような構成とすることで、導線２の全周に同一幅の絶縁層３ａを形成させることができる。よって導線２の全周に亘って絶縁性能を高く保持させることができる。 The insulating layer 3 a is a layer composed of a non-fusible resin coated on the outer periphery of the conducting wire 2. Thus, it becomes possible to set it as the insulated wire 1 which suppressed cost by using non-fusing resin. Moreover, the insulating layer 3a has the same outer peripheral shape as the conducting wire 2, as shown in FIG. By setting it as such a structure, the insulating layer 3a of the same width can be formed in the perimeter of the conducting wire 2. FIG. Therefore, high insulation performance can be maintained over the entire circumference of the conducting wire 2.
絶縁層３ａに用いる樹脂としては、例えばポリエウレタン、ポリエステル、ポリエステルイミド、ポリアミドイミド、ポリイミド等、コイル用絶縁電線に一般的に用いられる樹脂のうち１種類、あるいは２種類以上組み合わせた樹脂を用いる事が出来る。またポリエウレタン、ポリエステル、ポリエステルイミド、ポリアミドイミド、ポリイミド等、コイル用絶縁電線に一般的に用いられる樹脂のうち１種類、あるいは２種類以上組み合わせた樹脂が２層以上の多層構造を形成していても構わない。 As the resin used for the insulating layer 3a, for example, one or a combination of two or more kinds of resins generally used for insulated wires for coils, such as polyurethane, polyester, polyesterimide, polyamideimide, and polyimide, should be used. I can do it. In addition, one or a combination of two or more types of resins commonly used for insulated wires for coils, such as polyurethane, polyester, polyesterimide, polyamideimide, polyimide, etc., form a multilayer structure of two or more layers. It doesn't matter.
また絶縁層３ａを導線２の外周へ被覆させる方法は、公知の被覆技術を用いれば良く、例えば樹脂を溶剤に溶かした溶液を導体２の外周に十分に滴下させたり、溶液の浴に浸漬させたりして被覆させるディッピング法、溶液に電荷付与剤を添加した浴に浸漬して電着する電着法等が挙げられる。その後、乾燥工程により、溶剤を除去し絶縁層３ａとして形成させる。
また樹脂を溶かす溶剤としては、公知のものを適用すれば良く、例えばディッピング法では、クレゾール、トルエン、キシレン、ナフサ、プロピレングリコール、エチレングリコール、グリセリン、ジメチルテレフタレート、アルコール類、Ｎ−メチル−２−ピロリドン（ＮＭＰ）、ジメチルアセトアミド（ＤＭＡｃ）、ジメチルホルムアミド（ＤＭＦ）が挙げられ、電着法ではアルコール類、水等が挙げられる。
Also, a known coating technique may be used to coat the insulating layer 3a on the outer periphery of the conducting wire 2. For example, a solution obtained by dissolving a resin in a solvent may be sufficiently dropped on the outer periphery of the conductor 2 or immersed in a solution bath. For example, a dipping method in which the electrode is coated and an electrodeposition method in which electrodeposition is performed by dipping in a bath in which a charge imparting agent is added to the solution. Thereafter, the solvent is removed by a drying process to form the insulating layer 3a.
As the solvent for dissolving the resin, a known solvent may be applied. For example, in the dipping method, cresol, toluene, xylene, naphtha, propylene glycol, ethylene glycol, glycerin, dimethyl terephthalate, alcohols, N-methyl-2- Examples include pyrrolidone (NMP), dimethylacetamide (DMAc), and dimethylformamide (DMF). Examples of the electrodeposition method include alcohols and water.
また絶縁層３ａには、放熱用フィラーを含有させている。このような構成とすることで、放熱性を一段と向上させることができる。
放熱用フィラーとしては、ＢＮ、ＳｉＣ、ＡｌＮ、Ａｌ２Ｏ３、ＳｉＮ、ＳｉＯ２、ＭｇＯ、ＺｎＯ、ＴｉＯ２等があり、これらの無機絶縁材料から適宜選択して用いることができる。例えばＢＮの熱伝導率は約２１０（Ｗ／ｍ・Ｋ）であり、ＳｉＣの熱伝導率は２７０（Ｗ／ｍ・Ｋ）であり、ＡｌＮの熱伝導率は約１７０（Ｗ／ｍ・Ｋ）であり、樹脂材料の熱伝導率（０．２Ｗ／ｍ・Ｋ前後）よりも極めて高い。またＡｌ２Ｏ３の熱伝導率は約３６（Ｗ／ｍ・Ｋ）であり、ＲＮ等に比べると低いが、価格が安いので、フィラーを混入させるための製造コストの増大を抑制することができる利点がある。
尚、絶縁層３ａには、放熱用フィラーに加えて、酸化防止剤、潤滑剤、顔料、染料等を適宜添加しても勿論よい。また絶縁層３ａの幅は、用途に応じて適宜変更可能である。
The insulating layer 3a contains a heat radiation filler. By setting it as such a structure, heat dissipation can be improved further.
Examples of the heat dissipating filler include BN, SiC, AlN, Al 2 O 3 , SiN, SiO 2 , MgO, ZnO, TiO 2, and the like, which can be appropriately selected from these inorganic insulating materials. For example, the thermal conductivity of BN is about 210 (W / m · K), the thermal conductivity of SiC is 270 (W / m · K), and the thermal conductivity of AlN is about 170 (W / m · K). It is extremely higher than the thermal conductivity (around 0.2 W / m · K) of the resin material. In addition, the thermal conductivity of Al 2 O 3 is about 36 (W / m · K), which is lower than that of RN or the like, but the price is low, so that it is possible to suppress an increase in manufacturing cost for mixing the filler. There are advantages you can do.
Of course, an antioxidant, a lubricant, a pigment, a dye, and the like may be appropriately added to the insulating layer 3a in addition to the heat radiation filler. The width of the insulating layer 3a can be changed as appropriate according to the application.
前記絶縁層３ｂは、絶縁層３ａの外周に被覆された非融着性の樹脂で構成される層であり、公知の被覆技術を適用して絶縁層３ａの外周に被覆される。このように絶縁層３ａの外周に絶縁層３ｂを設け、絶縁層３ａを内層とし、絶縁層３ｂを外層とする２層構造とすることで、耐油性、耐水性、耐磨耗性に優れた絶縁電線１とすることができる。また絶縁層が２層となることで、高温における被膜の軟化が少ない絶縁電線１とすることができる。更に絶縁抵抗を増大させることができ、絶縁性能を一段と高く保持させることができる。また絶縁層の外周形状、厚み等を内層と外層とで異なるものとすることができる。 The insulating layer 3b is a layer composed of a non-fusible resin coated on the outer periphery of the insulating layer 3a, and is coated on the outer periphery of the insulating layer 3a by applying a known coating technique. As described above, the insulating layer 3b is provided on the outer periphery of the insulating layer 3a, the insulating layer 3a is used as an inner layer, and the insulating layer 3b is used as an outer layer, so that it has excellent oil resistance, water resistance, and wear resistance. The insulated wire 1 can be obtained. Moreover, it can be set as the insulated wire 1 with few softening of the film in high temperature because an insulating layer becomes two layers. Further, the insulation resistance can be increased, and the insulation performance can be kept higher. Further, the outer peripheral shape and thickness of the insulating layer can be different between the inner layer and the outer layer.
また絶縁層３ｂの外周形状は、図１に示すように、導線２、絶縁層３ａとは異なる正六角形としている。このような構成とすることで、図２に示すように、絶縁コイル４を形成する際に、隣接する絶縁電線１を密接させることができる。よって隣接する絶縁電線１間に隙間が生じることを防止することができる。従って、隣接する絶縁電線１間に空気相が形成されることを防止でき、放熱性、耐サージ性を向上させることができる。また絶縁電線１をコイル用絶縁電線として有効に用いることができる。
また図１に示すように、本実施形態においては、絶縁層３ｂは各頂点部のみに厚みを有し、その他の部分は絶縁層３ａと接するように構成してある。このような構成とすることで、占積率を低下させることのない絶縁電線とすることができる。
勿論、このような構成とせず、絶縁層３ａの外周に同一幅で絶縁層３ｂを設けることも可能である。
Further, as shown in FIG. 1, the outer peripheral shape of the insulating layer 3b is a regular hexagon different from the conductive wire 2 and the insulating layer 3a. With such a configuration, as shown in FIG. 2, when forming the insulating coil 4, the adjacent insulated wires 1 can be brought into close contact with each other. Therefore, it is possible to prevent a gap from occurring between the adjacent insulated wires 1. Therefore, an air phase can be prevented from being formed between the adjacent insulated wires 1, and heat dissipation and surge resistance can be improved. Moreover, the insulated wire 1 can be used effectively as an insulated wire for coils.
As shown in FIG. 1, in this embodiment, the insulating layer 3b has a thickness only at each apex portion, and the other portions are configured to be in contact with the insulating layer 3a. By setting it as such a structure, it can be set as the insulated wire which does not reduce a space factor.
Of course, without having such a configuration, it is possible to provide the insulating layer 3b with the same width on the outer periphery of the insulating layer 3a.
絶縁層３ｂに用いる樹脂としては、例えばエポキシ樹脂、フェノール樹脂等の様な、非融着性の熱硬化生樹脂を用いる事が出来る他、ポリエウレタン、ポリエステル、ポリエステルイミド、ポリアミドイミド、ポリイミド等、コイル用絶縁電線に一般的に用いられる非融着性の樹脂のうち１種類、あるいは２種類以上組み合わせた樹脂用いる事が出来る。また当該絶縁電線の使用温度範囲が、絶縁層３ｂを融着させない温度範囲である場合はポリアミド、ポリエーテルイミド、ポリエーテルスルホン、ポリエーテルエーテルケトン、フェノキシ、各種フッ素樹脂等の熱可塑性樹脂を用いる事も出来る。 As the resin used for the insulating layer 3b, for example, a non-fusible thermosetting resin such as an epoxy resin and a phenol resin can be used, and a polyurethane, polyester, polyester imide, polyamide imide, polyimide, etc. One type or a combination of two or more types of non-fusible resins generally used for coil insulated wires can be used. When the temperature range of use of the insulated wire is a temperature range in which the insulating layer 3b is not fused, a thermoplastic resin such as polyamide, polyetherimide, polyethersulfone, polyetheretherketone, phenoxy, or various fluororesins is used. You can also do things.
また絶縁層３ｂを絶縁層３ａの外周へ被覆させる方法は、公知の被覆技術を用いれば良く、例えば樹脂を溶剤に溶かした溶液を絶縁層３ａの外周に十分に滴下させたり、溶液の浴に浸漬させたりして被覆させるディッピング法、溶液に電荷付与剤を添加した浴に浸漬して電着する電着法等が挙げられる。その後、乾燥工程により、溶剤を除去し絶縁層３ｂとして形成させる。
また樹脂を溶かす溶剤としては、公知のものを適用すればよく、既述した溶剤を用いることができる。
また当該絶縁電線の使用温度範囲が、絶縁層３ｂを融着させない温度範囲であり、絶縁層３ｂに用いる樹脂として、ポリアミド、ポリエーテルイミド、ポリエーテルスルホン、ポリエーテルエーテルケトン、フェノキシ、各種フッ素樹脂等の熱可塑性樹脂を用いる場合は、ディッピング法のみならず、樹脂の溶融押しによる被覆を行っても構わない。
The insulating layer 3b may be coated on the outer periphery of the insulating layer 3a using a known coating technique. For example, a solution in which a resin is dissolved in a solvent is sufficiently dropped on the outer periphery of the insulating layer 3a, or the solution is bathed in a solution. Examples thereof include a dipping method in which the coating is performed by dipping, and an electrodeposition method in which electrodeposition is performed by dipping in a bath in which a charge imparting agent is added to the solution. Thereafter, the solvent is removed by a drying process to form the insulating layer 3b.
Moreover, what is necessary is just to apply a well-known thing as a solvent which melt | dissolves resin, and the already described solvent can be used.
Moreover, the use temperature range of the insulated wire is a temperature range in which the insulating layer 3b is not fused, and as the resin used for the insulating layer 3b, polyamide, polyetherimide, polyethersulfone, polyetheretherketone, phenoxy, various fluororesins When a thermoplastic resin such as the above is used, coating may be performed not only by the dipping method but also by melt pressing of the resin.
また絶縁層３ｂには、放熱用フィラーをさせている。このような構成とすることで、放熱性を一段と向上させることができる。
放熱用フィラーとしては、ＢＮ、ＳｉＣ等既述した放熱用フィラーを用いることができる。
尚、絶縁層３ｂの外周形状は正六角形に限られるものではなく、隣接する絶縁電線を密接させることができる形状であれば、正方形、長方形、多角形等如何なる形状であってもよい。また、必ずしも絶縁層３ｂの各頂点部のみに厚みを有し、その他の部分は絶縁層３ａと接するような構成とする必要もなく、如何なる構成であってもよい。

As the heat dissipating filler, the heat dissipating filler described above such as BN and SiC can be used.
Note that the outer peripheral shape of the insulating layer 3b is not limited to a regular hexagon, and may be any shape such as a square, a rectangle, or a polygon as long as the adjacent insulated wires can be brought into close contact with each other. In addition, it is not always necessary to have a thickness only at each apex of the insulating layer 3b, and the other portions may be in contact with the insulating layer 3a, and any configuration may be used.
