ぎられたり、また引き抜き困難のため、固い素子を作る
ことができず、また広巾の素子を作る場合は、巻き取り
時にしわが発生するなどの問題点があった。However, in such a manufacturing method, when the split winding shaft 8 is pulled out from the roll-shaped formed product, the pinched portion is torn off, or because it is difficult to pull out, a solid element cannot be made, and a wide element When making, there were problems such as wrinkles occurring during winding.
（考案が解決しようとする問題点） 本考案の目的は，このような製作上の問題点のないより
良好な電解コンデンサー素子を提供することである。(Problems to be Solved by the Invention) An object of the present invention is to provide a better electrolytic capacitor element having no such manufacturing problems.
（問題点を解決するための手段） 本願考案者は、この目的を達成するため鋭意研究の結

案するに至った。(Means for Solving the Problems) As a result of earnest research to achieve this object, the inventor of the present invention has realized that a hollow cylindrical core is used and an element material is wound around the core. Multiple openings 3 in
The present inventors have devised an electrolytic capacitor element in which a strip-shaped electrolytic capacitor element material 7 is wound around a hollow cylindrical core 1 having.
本願考案の電解コンデンサー素子を製作するには、巻取
軸10を中空円筒状のコア１の中心孔２に挿入嵌合した
後、該円筒状コア１に素子材料７を巻き着けて巻物状に
形成した後、巻取軸10を中心孔２から引き抜くことによ
って完成する。而して、本願考案においては、中空円筒
状のコア１は側面に複数個の開口部３を設け、この開口
部を通って素子の中心部に発生する熱を万遍なく放熱さ
せる。また、ほぼ均等の位置間隔に設けられた複数個の
開口部は単一のより大きい開口部よりもコアにとって強
度的にもまた放熱効果の点においても有利である。In order to manufacture the electrolytic capacitor element of the present invention, the winding shaft 10 is inserted and fitted into the center hole 2 of the hollow cylindrical core 1, and then the element material 7 is wound around the cylindrical core 1 to form a scroll. After forming, the winding shaft 10 is completed by pulling it out from the center hole 2. Thus, in the present invention, the hollow cylindrical core 1 is provided with a plurality of openings 3 on its side surface, and the heat generated in the central portion of the element through the openings is evenly radiated. Further, the plurality of openings provided at substantially equal position intervals are more advantageous to the core in terms of strength and heat dissipation effect than a single larger opening.
（効果） 本考案の電解コンデンサー素子は、その製作において
は、従来の製作方法のように、巻物状形成物から巻取軸
を引き抜くのに何らの困難も問題点もなく、固く巻き着
けることもできるので、一定の固さの素子を作ることが
可能で、また巻取外径を一定にすることも可能である。(Effect) In the production of the electrolytic capacitor element of the present invention, there is no difficulty or problem in pulling out the winding shaft from the roll-shaped formed product as in the conventional production method, and it can be firmly wound. As a result, it is possible to make an element having a constant hardness, and it is also possible to make the winding outer diameter constant.
さらに、電解コンデンサーが超大型化している現在で
は、電極箔から引き出すタブの本数が増加（コンデンサ
ーの特性インピーダンスを低くするため）する傾向にあ
り、その点コアを使用することにより、次のごとき利点
が得られる。Furthermore, at the present time when electrolytic capacitors have become extremely large, the number of tabs drawn out from the electrode foil tends to increase (to reduce the characteristic impedance of the capacitor). In that respect, the use of a core has the following advantages. Is obtained.
１）一定の固さの素子に巻取ることができる。1) It can be wound into an element having a certain hardness.
２）巻取外径が量産時にも安定している。2) The winding outer diameter is stable even during mass production.
３）引き出しタブの本数が多くなっても，タブ合せで精
度が優れている。3) Even if the number of pull-out tabs is large, the accuracy of tab matching is excellent.
４）広巾の材料（170mm巾以上）を巻き取ってもしわの
影響がない。4) Even if a wide material (170 mm width or more) is wound up, there is no wrinkle effect.
５）巻取素子からの巻取軸の引き抜きが容易である。5) It is easy to pull out the winding shaft from the winding element.
さらに、素子の中心部にコアを有するため、このコアを
利用することによって、 １）素子をケースに固定することができる。Further, since the element has a core in the central portion, by using this core, 1) the element can be fixed to the case.
２）コアの中心孔２に安全装置（ヒューズ等）を入れる
ことができる。2) A safety device (fuse or the like) can be placed in the center hole 2 of the core.
３）素子中心部の発生した熱をコアの開孔部３を通して
ケースに放熱させるラジエーション効果を得ることがで
きる。3) It is possible to obtain a radiation effect in which the heat generated in the central portion of the element is radiated to the case through the opening 3 of the core.
