巻回された巻回型コンデンサ素子の前記筒形ボビ
ンの下端孔部を除く外周面部を容器により巻回両
端面に面して各別に間隙を形成せしめて包囲し、
かつ容器内および筒形ボビンの孔内に絶縁ガスを
充填すると共に、容器のまわりを合成樹脂でモー
ルドするに際して筒形ボビンの孔内に合成樹脂を
流入させ加圧状態とすることにより容器内の絶縁
ガスを正圧状態に密封せしめて一体にモールドし
たことを特徴とするモールドコンデンサ。 In a wound type capacitor element in which band-shaped dielectric layers and electrode layers are alternately wound around a cylindrical bobbin, the outer circumferential surface of the cylindrical bobbin, excluding the lower hole, is wound with a container, and each layer is separately wound facing both end surfaces. Form a gap and surround it,
In addition, the inside of the container and the hole of the cylindrical bobbin are filled with insulating gas, and when the container is molded with synthetic resin, the synthetic resin is flowed into the hole of the cylindrical bobbin to create a pressurized state. A molded capacitor characterized by being integrally molded with insulating gas sealed under positive pressure.
