Description
【考案の詳細な説明】
本考案は乾電池の耐漏液性を向上することを目的とする
。[Detailed description of the invention] The purpose of the invention is to improve the leakage resistance of dry batteries.
従来の乾電池は第１図に示すように、発電要素を内填し
た亜鉛線１の下面に、陰極端子板２を当接し、亜鉛線１
の側面を包被する樹脂チューブ３の下端を陰極端子板２
の下面周縁に沿って内方に折り曲げ、樹脂チューブ３の
下端折曲部にシールリング４を当接して外装筒５で締め
つけていた。As shown in Fig. 1, in a conventional dry battery, a cathode terminal plate 2 is brought into contact with the lower surface of a zinc wire 1 containing a power generating element, and the zinc wire 1
The lower end of the resin tube 3 that covers the side surface of the cathode terminal plate 2
The resin tube 3 was bent inward along its lower peripheral edge, a seal ring 4 was brought into contact with the bent portion of the lower end of the resin tube 3, and the outer tube 5 was tightened.
この構造では陰極端子板２と樹脂チューブ３が平面で接
触しているため、両者の接面庫が低く、シたがって亜鉛
線１の外に出た電解液が樹脂チューブ３の内面を伝わっ
て下方に下り、陰極端子板２と樹脂チューブ３の接面か
ら外部へ漏出する欠点があった。In this structure, the cathode terminal plate 2 and the resin tube 3 are in plane contact, so the contact surface between them is low, and therefore the electrolyte that has come out of the zinc wire 1 is transmitted along the inner surface of the resin tube 3. There was a drawback that the liquid leaked downward from the contact surface between the cathode terminal plate 2 and the resin tube 3 to the outside.
また樹脂チューブ３を陰極端子板２に強固に押しつけよ
うとするために、ｈ 製筒５の締めつけ力を大にすれば
、外装筒５の開Ｕ１ｆ４のエツジがシールリング４に当
接しているため、シールリング４が破れることなどがあ
った。In addition, in order to firmly press the resin tube 3 against the cathode terminal plate 2, if the tightening force of the tube 5 is increased, the edge of the opening U1f4 of the outer tube 5 will come into contact with the seal ring 4. , the seal ring 4 was sometimes torn.
本考案はこのような従来の欠点を解悄したもので、第２
図ならびに第３図について説明する。The present invention solves these conventional drawbacks and is the second
The figure and FIG. 3 will be explained.
発電要素を内填した亜鉛線２１を被包する樹脂チューブ
２２の下端を内方に折り曲げて亜鉛線２１の底部に密着
させ、この樹脂チューブ２２の下端折曲部に第３図に示
す陰極端子板２３の上面周縁に設けた環状突部２４を当
接し、かつ陰極端子板２３の周縁の平滑部２７をシール
リング２５を介して外装筒２９の水平部２８で締めつけ
て陰極端子板２３を亜鉛線２１の底部に密着させる。The lower end of the resin tube 22 enclosing the zinc wire 21 containing the power generating element is bent inward and brought into close contact with the bottom of the zinc wire 21, and the cathode terminal shown in FIG. 3 is attached to the lower end bent portion of the resin tube 22. The annular protrusion 24 provided on the periphery of the upper surface of the plate 23 is abutted, and the smooth portion 27 of the periphery of the cathode terminal plate 23 is tightened with the horizontal portion 28 of the exterior cylinder 29 via the seal ring 25, thereby sealing the cathode terminal plate 23 with zinc. Bring it into close contact with the bottom of the wire 21.
本考案はこのような構造になっており、特に陰極端子板
２３の周縁の平滑部２７を外装筒２６の水平部２８で締
めつけているため外装筒２６の締めつけ力が陰極端子板
２３の上面周縁に設けられた環状突部２４に集中するか
ら、陰極端子板２３の環状突部２４、樹脂チューブ２２
、亜鉛線２１の相互間の接面圧が極めて高く、液密的に
密着し、そのため亜鉛線２１の外に出た電解液が樹脂チ
ューブ２２の内面を伝わって下に下っても外部へ漏出す
ることがない。The present invention has such a structure, in particular, since the smooth portion 27 on the periphery of the cathode terminal plate 23 is tightened by the horizontal portion 28 of the outer tube 26, the tightening force of the outer tube 26 is applied to the upper surface periphery of the cathode terminal plate 23. The annular protrusion 24 of the cathode terminal plate 23 and the resin tube 22 concentrate on the annular protrusion 24 provided in the
, the contact pressure between the zinc wires 21 is extremely high and they are in close contact with each other in a liquid-tight manner, so that even if the electrolyte that has come out of the zinc wires 21 travels down the inner surface of the resin tube 22 and goes down, it will not leak to the outside. There's nothing to do.
また、第４図に示すように樹脂チューブ３１の下端周縁
をシールリング３２を介して亜鉛線３３の底部に密着さ
せておけば、より一層液密性が向上される。Further, as shown in FIG. 4, if the lower end peripheral edge of the resin tube 31 is brought into close contact with the bottom of the zinc wire 33 via the seal ring 32, the liquid tightness is further improved.
