＜従来の技術＞
変圧器やその他の各種コイル装置を構成する場
合、従来は、例えば第１図に示すように、コイル

コイル２０１〜２０ｎのコイル端末イは、第２図
に示すように粘着テープ４によつて固定する。<Prior Art> When configuring a transformer or other various coil devices, conventionally, as shown in FIG. While sandwiching the coils, the coils 201 to 20n were wound by the necessary number of layers n.
The coil terminals A of the coils 201 to 20n are fixed with adhesive tape 4 as shown in FIG.
このようにしてコイル２０１〜２０ｎを巻装し
た後、絶縁耐圧を高めるため、ケースに挿入する

お、１０２及び１０３は鍔部、１０４はコア挿入
孔である。 After winding the coils 201 to 20n in this manner, the coils are inserted into a case, impregnated with an insulating resin, and cured in order to increase the dielectric strength. Note that 102 and 103 are collar portions, and 104 is a core insertion hole.
＜考案が解決しようとする課題＞

１〜３０ｎを介在させ、最後に絶縁樹脂を含浸さ
せる構造であるため、製造、組立工程が複雑で、
処理に長時間を要し、能率が悪い。<Problem to be solved by the invention> However, the above-described conventional coil device has an insulating film 30 between each layer of the coils 201 to 20n.
Since the structure involves intervening 1 to 30n and finally impregnating with insulating resin, the manufacturing and assembly process is complicated.
Processing takes a long time and is inefficient.
しかも、コイル２０１〜２０ｎが絶縁フイルム

隙間がなくなるため、絶縁樹脂含浸工程におい

電を生じてしまうことがある。 Moreover, since the coils 201 to 20n are tightly wound on the surface of the insulating films 301 to 30n, with almost no gaps, each coil 201 to 20n is not sufficiently impregnated with the insulating resin in the insulating resin impregnation step. Voids may occur and corona discharge may occur.

の問題点も有している。 Furthermore, as shown in FIG. 2, the coil end A is fixed using an adhesive tape 4 or the like, which also makes manufacturing and assembly complicated and reduces efficiency. When processing coil terminal A, coils 201 to 2
Rolling collapse occurs at 0n, which tends to cause voids and corona discharge due to the voids. Since the adhesive tape 4 is in close contact with the coil bobbin 1 or the insulating films 301 to 30n, there are also problems such as insufficient penetration of the insulating impregnated resin.

イルと樹脂とを密着させてボイドの発生を防止す
るようにしてあつた。 As a conventional technique aimed at preventing voids, there is a technique described in Japanese Patent Publication No. 47-45133. In this conventional technology, a coil is wound using an interlayer material made of coarsely braided glass cloth coated with semi-condensed epoxy resin, and during molding, the semi-condensed epoxy resin and the epoxy resin added from the outside are integrally condensed into a coil. and the resin were brought into close contact to prevent the generation of voids.

ラスクロスに対する半縮合エポキシ樹脂の塗布が
不均一になり、ガラスクロスに半縮合エポキシ樹
脂の塗布されない部分が生じ、この部分がボイド
発生の原因となることがある。 However, in this conventional technology, the semi-condensed epoxy resin is not applied uniformly to the coarsely braided glass cloth, and there are parts of the glass cloth where the semi-condensed epoxy resin is not applied, which causes voids to occur. There is.
また、ガラスクロスの両面側の半縮合エポキシ
樹脂が、区画されることなく、互いに結合される
ので、半縮合エポキシ樹脂層の変形が相互に影響
し合い、コイルの巻崩れ等を生じ易い。 Moreover, since the semi-condensed epoxy resins on both sides of the glass cloth are bonded to each other without being partitioned, the deformation of the semi-condensed epoxy resin layers influences each other, making it easy for the coil to collapse.
そこで、本考案の課題は上述する従来の問題点

る。<Function> The insulating layer includes a thermoplastic insulating layer welded to the coil, and the thermoplastic insulating layer is a thermoplastic insulating resin film or a thermoplastic insulating resin coating layer provided by laminating the heat-resistant insulating resin film. Since the thermoplastic insulating layer is made of a layer that is heated and welded, by heat treatment, the thermoplastic insulating layer can be thermally melted and infiltrated around the coil. For this reason,
The insulating resin impregnation process is no longer necessary, simplifying the manufacturing and assembly process and improving manufacturing efficiency. Further, the thermoplastic insulating layer can be sufficiently penetrated into each coil by thermal melting, thereby preventing voids and corona discharge caused by each coil. Furthermore, the entire coil is fixed by the thermoplastic insulating layer, making it unnecessary to fix the ends of the coil with adhesive tape or the like, which also simplifies the manufacturing and assembly process and shortens the processing time. Furthermore, since the coil does not collapse, the generation of voids and corona discharge can be prevented.

とができる。 In addition, since it includes a heat-resistant insulating resin film arranged to divide the thermoplastic insulating layer into each coil layer, it is different from the conventional technology using an interlayer material made of coarsely braided glass cloth coated with semi-condensed epoxy resin. Differently, there is almost no space around the coil where there is no insulating resin, and voids are extremely unlikely to occur. Even if voids occur in the thermoplastic insulating layer, insulation is ensured by the heat-resistant insulating resin film, and a predetermined dielectric strength voltage can be obtained.
