本発明は誘電体フィルムの片面に電極を形成した片面金
属化フィルムを巻回することにより構成される巻回型コ
ンデンサの製造方法に関するもので、詳しくは生産性の
高い製造方法を提供するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a wound type capacitor which is constructed by winding a single-sided metallized film having an electrode formed on one side of a dielectric film. A manufacturing method is provided.
従来、片面金属化フィルムを巻回して構成した巻回型コ
ンデンサは、第１図に示すような構成であり、片面金属
化フィルム１の端面部にフィルム間隙２を形成するため
に、２枚の片面金属化フィルム１をずらせた状態で巻取
っている。Conventionally, a wound type capacitor constructed by winding a metalized film on one side has a structure as shown in FIG. The single-sided metallized film 1 is wound up in a shifted state.
これによってフィルム間隙３を形成して素子端面にメタ
リコンにより形成するコンタクト層の喰い込みを充分な
ものとし、片面金属化フィルム１の電極１ａとの間に良
好な接触を得るためのものである。This is to form a film gap 3 to allow sufficient penetration of the contact layer formed of metallicon on the end face of the element, and to obtain good contact with the electrode 1a of the single-sided metallized film 1.
なお、第１図において３はマージン部、４はマージン幅
である。In FIG. 1, 3 is a margin portion, and 4 is a margin width.
このように巻回コンデンサで片面金属化フィルムを使用
するものにおいては、片面金属化フィルムの巻取り時に
高精度が要求され、従って複数のコンデンサ要素を有す
る片面金属化フィルムを巻回した後、単位コンデンサに
切断する製造方法を使用する場合は、フィルム間隙が形
成されないため、採用できず生産性を上げる上で不利で
あった。In this way, in the case of using a single-sided metalized film in a wound capacitor, high precision is required during the winding of the single-sided metalized film, and therefore, after winding the single-sided metalized film with multiple capacitor elements, the unit When using a manufacturing method in which the capacitor is cut into capacitors, a film gap is not formed, so this cannot be used and is disadvantageous in terms of increasing productivity.
このため、現在は複数のコンデンサ要素を有する片面金
属化フィルムを単位コンデンサ要素に分割した後、片面
金属化フィルムを巻回して製造している。For this reason, currently, a single-sided metalized film having a plurality of capacitor elements is divided into unit capacitor elements, and then the single-sided metalized film is wound.
本発明はこのような従来の問題点に鑑み成されたもので
、以下本発明の巻回型コンデンサの製造方法について第
２図〜第４図の図面とともに説明する。The present invention has been made in view of such conventional problems, and the method of manufacturing a wound type capacitor according to the present invention will be explained below with reference to the drawings of FIGS. 2 to 4.
本発明の製造方法では、第２図に示すようにマージン部
５に点在するように複数の貫通孔６を設けた片面金属化
フィルム７を使用するものである。The manufacturing method of the present invention uses a single-sided metallized film 7 in which a plurality of through holes 6 are provided so as to be scattered in the margin portion 5, as shown in FIG.
なお、第２図において７３は電極である。In addition, in FIG. 2, 73 is an electrode.
また、本発明の片面金属化フィルム７の切断端面は凹凸
状となり、従って片面金属化フィルム１１を巻回した時
には巻回物の端面の片面金属化フィルム７間は凹凸とな
る。Further, the cut end surface of the single-sided metallized film 7 of the present invention has an uneven shape, so when the single-sided metalized film 11 is wound, the space between the single-sided metalized film 7 on the end face of the wound product becomes uneven.
次に、本発明の詳細な説明する。Next, the present invention will be explained in detail.
第３図および第４図に本発明の実施例による巻回型コン

分割されるのである。3 and 4 show manufacturing steps in a method for manufacturing a wound capacitor according to an embodiment of the present invention, in which a plurality of electrodes 7a are formed so as to form a plurality of capacitor elements.
and a wide single-sided metallized film 7 with a margin 6 formed thereon.
The plurality of single-sided metallized films 7 are overlapped and wound so that the margin parts 6 are shifted by % of the length between the margin parts 6, and this rolled product is wrapped around the margin part 5.
By cutting at this point, it is divided into individual capacitor elements.
すなわち、本実施例による製造方法では、複数のコンデ
ンサ要素を有する片面金属化フィルム７を巻回した後、
個々のコンデンサ素子に分割するものであるため、生産
性よくコンデンサ素子を製造することができる。That is, in the manufacturing method according to this embodiment, after winding the single-sided metallized film 7 having a plurality of capacitor elements,
Since the capacitor elements are divided into individual capacitor elements, the capacitor elements can be manufactured with high productivity.
以上のように本発明による巻回型コンデンサの製造方法
