Description
本発明は、開放型の鉛蓄電池等のように注液口に液口栓を装着した蓄電池に関するものである。 The present invention relates to a storage battery in which a liquid stopper is attached to a liquid injection port, such as an open lead-acid battery.
開放型の鉛蓄電池は、充電中の電気分解により酸素ガスと水素ガスが発生するので、蓋板の注液口に装着する液口栓に排気孔を設けてこれらのガスを大気中に排出するようになっている。しかしながら、液口栓にこのような排気孔が開口していると、例えば鉛蓄電池を搭載している自動車が走行時に上下振動を受けて電解液が電槽内で跳ねたような場合に、この排気孔を通して電解液が溢液するおそれが生じる。 An open-type lead-acid battery generates oxygen gas and hydrogen gas due to electrolysis during charging. Therefore, an exhaust hole is provided in the liquid stopper attached to the liquid injection port of the lid plate, and these gases are discharged into the atmosphere. It is like that. However, when such an exhaust hole is opened in the liquid plug, for example, when an automobile equipped with a lead storage battery is subjected to vertical vibration during traveling and the electrolyte splashes in the battery case, There is a risk that the electrolyte will overflow through the exhaust hole.
そこで、従来の液口栓は、電槽内部に突出する筒部内に傾斜した半円状の水平防沫板を複数枚組み合わせて配置し、この筒部の上方の排気孔に至る通気路を迷路状とすることにより、電槽内で発生したガスは通すが、電解液の飛沫は容易には排気孔から外部には溢液しないようにしていた（例えば、特許文献１参照。）。 Therefore, the conventional liquid spigot is arranged by combining a plurality of inclined semicircular horizontal splash-proof plates in the cylindrical portion protruding into the battery case, and the ventilation path leading to the exhaust hole above the cylindrical portion is a maze. The gas generated in the battery case is allowed to pass through, but the splash of the electrolytic solution is not easily overflowed from the exhaust hole to the outside (see, for example, Patent Document 1).
また、最近では、四輪駆動やラフロード走行仕様の自動車の増加に伴い、これらの自動車に搭載した鉛蓄電池が受ける振動も強さが増大するだけでなく、上下（垂直方向）振動に加えて横（水平方向）振動も加わるようになって来たために、上記水平防沫板の下方に垂直防沫板を複数枚配置して、横振動による電解液の飛沫の水平方向への飛散をこの垂直防沫板で遮断すると共に、上下振動による飛沫の垂直方向への飛散を水平防沫板で遮断するようにした液口栓も提案されている（例えば、特許文献２参照。）。 Recently, with the increase in automobiles with four-wheel drive and rough road driving specifications, not only does the strength of vibrations received by lead-acid batteries mounted on these vehicles increase, but in addition to vertical (vertical) vibrations, (Horizontal direction) Since vibration has come to be applied, a plurality of vertical splash-proof plates are arranged below the horizontal splash-proof plate, and the vertical scattering of electrolyte splashes due to lateral vibration is this vertical. There has also been proposed a liquid spigot that is blocked by a splash-proof plate and that is blocked by a horizontal splash-proof plate from splashing in the vertical direction due to vertical vibration (see, for example, Patent Document 2).
ところが、上記液口栓は、いずれも振動溢液性能を向上させるためのものであり、静的溢液性能については十分に考慮されているとはいえないという問題があった。即ち、振動溢液性能を向上させるために、電解液の進入口が液口栓の筒部のできるだけ下方に限定されるように、この筒部の筒部スリットをあまり高い位置まで形成しなかった。このため、充電による電解液の液位の上昇により、この筒部のスリットが電解液に完全に浸かると、電槽内でガスが発生して内圧が上昇したときに、この筒部内の電解液の液位がさらに上昇し溢液を生じるおそれがある。しかも、近年の鉛蓄電池の高エネルギー密度化の要求に伴い、電槽内の電解液の液面と蓋板の内面側との間の空間が狭くなる傾向があるので、液口栓の筒部内の迷路状の通気路を上下に十分長くすることができないようになって来ている。このため、液口栓の筒部内に多数の水平防沫板と垂直防沫板を上下に配置することが困難になり、振動溢液性能自体も制限せざるを得なくなって来ている。
本発明は、中央部にスリットを形成した防沫板を組み合わせることにより、静的溢液性能が不十分であり筒部も上下方向に長くなりすぎるという問題を解決しようとするものである。 The present invention, by combining an anti-smear plate in which a slit is formed in the central portion, it is intended to solve the problem of static溢液performance too becomes longer in the vertical direction are cylindrical portion insufficient.
請求項１の発明は、注液口に液口栓を備えた蓄電池において、この液口栓の下端部から電池容器内部に突出する筒部における周側壁の前後位置に上下に細長い一対の筒部スリットが形成され、この液口栓の筒部内に、この筒部の内筒の下端部を塞ぐ防沫底板と、この防沫底板上に立設され、前後一対の筒部スリットの間の空間の左右側を覆うように壁板状に前後方向に沿うと共に、この前後方向の中央部に上下の縦板スリットが形成された一対の防沫縦板と、これら一対の防沫縦板の間の上方を覆う防沫天井板と、この防沫天井板の上方で筒部の内筒を塞ぐと共に、左右方向の中央部に庇スリットが形成された防沫庇板とが配置されたことを特徴とする。 The invention according to claim 1 is a storage battery having a liquid spout at a liquid inlet, and a pair of cylindrical portions elongated vertically in front and rear positions of a peripheral side wall in a cylindrical portion protruding from the lower end of the liquid spout into the battery container. slits are formed, in the cylinder portion of the liquid spout, the inner cylinder infarction instrument explosion smear bottom plate lower end portion of the cylindrical portion is erected to the splash-proof bottom plate, between the front and rear of the cylindrical portion slit A pair of splash-proof vertical plates with a vertical plate slit formed in the center in the front-rear direction, and a pair of splash-proof vertical plates that extend along the front-rear direction so as to cover the left and right sides of the space, and between the pair of splash-proof vertical plates features and splash proof ceiling plate for covering the upper, above the splash-proof ceiling plate with closing the inner cylinder of the cylindrical portion, that the anti-smear eave plate eaves slits are formed is disposed in a central portion in the lateral direction And
請求項１の発明によれば、電解液の飛沫は、まず上方に飛散するだけのものは防沫底板によって遮断され、水平方向のうちの前後に飛散する方向成分を有するものだけが筒部スリットを通り抜けて、筒部内における一対の防沫縦板の間に入り込む。次に、この飛沫のうちの左右に飛散する方向成分を有するものだけが各防沫縦板の縦板スリットを通り抜けて左右両側に至る。そして、この飛沫のうちの上方に飛散する方向成分を有するものだけが防沫天井板の上方に至るが、この飛沫も防沫庇板によって上昇が遮られる。従って、電池容器内部で発生したガスは、この防沫庇板の中央部の庇スリットを通り抜けてさらに上方の排気孔から外部に放出されるが、電解液の飛沫は、垂直と水平のあらゆる方向成分を有する飛沫を確実に遮断することができる。また、防沫底板と防沫庇板との間に一対の防沫縦板とこれらの間の上方を覆う防沫天井板を配置するだけなので、液口栓の筒部の上下長さを短くして蓄電池の高エネルギー密度化を図ると共に、筒部スリットの上端を十分に上方まで形成することにより充電による液位の上昇時にもこの筒部スリットが電解液に浸かってガスの排出路が塞がれるのを防ぐことができる。 According to the first aspect of the present invention, the splash of the electrolyte is first blocked only by the splash-proof bottom plate, and only the one having a directional component that scatters back and forth in the horizontal direction is the cylindrical slit. And enters between a pair of splash-proof vertical plates in the cylindrical portion. Next, only those having a directional component that scatters to the left and right of these splashes pass through the vertical plate slits of each splash-proof vertical plate and reach the left and right sides. And only the thing which has a direction component which scatters above among these splashes reaches the upper part of a splash-proof ceiling board, but this splash is also intercepted by a splash-proof board. Therefore, the gas generated inside the battery container passes through the throat slit in the central part of the splash proof plate and is discharged to the outside through the upper exhaust hole, but the electrolyte splashes in all directions, vertical and horizontal. The splash which has a component can be interrupted | blocked reliably. Moreover, since only a pair of splash-proof vertical plates and a splash-proof ceiling plate covering the upper part between them are disposed between the splash-proof bottom plate and the splash-proof saddle plate, the vertical length of the tube portion of the liquid spigot is shortened. In addition to increasing the energy density of the storage battery, by forming the upper end of the cylindrical slit sufficiently upward, the cylindrical slit is immersed in the electrolyte even when the liquid level rises due to charging, thereby blocking the gas discharge path. It can prevent peeling.
請求項１の発明は、前記液口栓の筒部内に、前記防沫庇板における庇スリットの上方を覆う防沫屋根板が配置されていてもよい。
このようにすれば、防沫庇板の上方にさらに防沫屋根板が配置されるので、上方に飛散する電解液の飛沫をさらに確実に遮ることができるようになる。なお、これら防沫庇板と防沫屋根板の組を、さらに上方に複数段にわたって配置することも可能である。
The invention of claim 1, in the cylinder portion of the liquid inlet plug, splash-proof roof plate covering the upper side of the eaves slit in the splash-proof eave plate may be disposed.
If it does in this way, since a splash-proof roof board is further arrange | positioned above a splash-proof siding board, the splash of the electrolyte solution which spreads upwards can be interrupted | blocked still more reliably. In addition, it is also possible to arrange | position the group of these splash-proof siding boards and splash-proof roof boards over several steps further upwards.
請求項１の発明は、前記防沫底板の左右両端部と、前記防沫庇板の庇スリットを介した左右両側部分とが、左右の外側を上方に向けて傾斜させて形成されると共に、前記防沫天井板の左右方向の中央を境としたこの左右両側部分が左右の外側を下方に向けて傾斜させて形成されていてもよい。
このようにすれば、防沫底板の左右両端部や防沫庇板や防沫天井板が傾斜して形成されているので、これらの防沫板によって遮られた電解液の飛沫を円滑に下方に導いて電池容器内に戻すことができるようになる。なお、この傾斜角度は、大きいほど飛沫を円滑に下方に導くことができるが、液口栓の筒部の上下長さを短くする必要もあるので、１０°程度とすることが好ましい。
In the invention of claim 1 , the left and right end portions of the splash-proof bottom plate and the left and right side portions through the heel slits of the splash-proof plate are formed with the left and right outer sides inclined upward, The left and right side portions may be formed with the left and right outer sides being inclined downward with the center in the left-right direction of the splash-proof ceiling plate as a boundary.
In this way, since the left and right ends of the splash-proof bottom plate, the splash-proof plate and the splash-proof ceiling plate are formed to be inclined, the splash of the electrolyte blocked by these splash-proof plates can be smoothly lowered. Can be returned to the battery case. In addition, although this inclination angle can guide a droplet smoothly downward, so that it is large, it is necessary to shorten the up-and-down length of the cylinder part of a liquid spout, Therefore It is preferable to set it as about 10 degrees.
請求項１の発明は、前記一対の防沫縦板が、それぞれ縦板スリットより前方側と後方側で少なくとも板厚分だけ左右にずれて形成されていてもよい。
このようにすれば、前後方向の中央部に縦板スリットが形成された防沫縦板の前方側と後方側が左右にずれて形成されているので、これらの防沫板を一体的に配置した防沫体を樹脂成形する際に、金型を前後２方向の抜き型だけで作製できるので、複雑な立体構造であるにもかかわらず、成形加工を容易にすることができる。
In the first aspect of the present invention, the pair of splash-proof vertical plates may be formed to be shifted left and right by at least the plate thickness on the front side and the rear side from the vertical plate slit.
In this way, since the front side and the rear side of the front-rear direction splash-proof vertical plate vertical plates slits are formed in the central portion of is formed deviated to the left and right, and place these anti smear plate integrally When the splash-proof body is resin-molded, the mold can be produced only by the front and rear two-direction punching mold, so that the molding process can be facilitated despite the complicated three-dimensional structure.
なお、これらにおける前後や左右の方向は、単に水平方向における互いに直交する方向を示すためのものであるため、実際の蓄電池の前後や左右の方向とは無関係である。 Incidentally, the front and rear and left and right direction definitive to these, since simply intended to indicate a direction orthogonal to each other in the horizontal direction, is independent of the longitudinal and lateral directions of the actual battery.
以下、本発明の最良の実施形態について図１〜図５を参照して説明する。 Hereinafter, the best embodiment of the present invention will be described with reference to FIGS.
本実施形態は、従来例と同様に、自動車用の鉛蓄電池について説明する。この鉛蓄電池は、樹脂製の方形容器状の電槽の上端開口部を樹脂製の蓋板で塞いで封止することにより電池容器が構成されている。また、電槽内は、隔壁によって複数のセル（例えば６セル）に仕切られ、それぞれのセルごとに発電要素が収納されると共に希硫酸の電解液が充填されている。そして、蓋板には、それぞれ各セルに通じる注液口が開口されていて、これらの注液口に図１に示す液口栓１がそれぞれ装着されることになる。なお、ここでは、トップフラットタイプの鉛蓄電池の例を示すので、注液口に装着された液口栓１は、蓋板の上面から上方に突出しない形状のものが用いられる。 This embodiment demonstrates the lead acid battery for motor vehicles similarly to a prior art example. In this lead storage battery, a battery container is formed by sealing the upper end opening of a resin-made rectangular container-shaped battery case with a resin lid plate. Further, the battery case is partitioned into a plurality of cells (for example, 6 cells) by a partition wall, and a power generation element is housed in each cell and filled with an electrolyte solution of dilute sulfuric acid. And the liquid injection port which leads to each cell is opened by the cover plate, respectively, and the liquid spigot 1 shown in FIG. 1 is each mounted | worn with these liquid injection ports. In addition, since the example of a top flat type lead-acid battery is shown here, the thing of the shape which does not protrude upwards from the upper surface of a cover plate is used for the liquid stopper 1 with which the liquid injection port was mounted | worn.
液口栓１は、樹脂製のボルト状の部品であり、上端部の円板状の頭部１１の下面から下方に向けて筒部１２を突設したものである。頭部１１の上面には十字形にコイン溝１１ａが形成されると共に、筒部１２の内筒に通じる小径の排気孔１１ｂが形成されている。筒部１２は、頭部１１の下面に近い上端部外周面にねじ部１２ａが形成されると共に、この筒部１２の周側壁の図示前方側と後方側に、それぞれ下端からねじ部１２ａの直下に至る上下に細長い筒部スリット１２ｂ，１２ｂが形成されている。 The liquid spigot 1 is a resin-made bolt-shaped component, and has a cylindrical portion 12 projecting downward from the lower surface of the disk-shaped head portion 11 at the upper end. A coin groove 11 a is formed in a cross shape on the upper surface of the head 11, and a small-diameter exhaust hole 11 b communicating with the inner cylinder of the cylinder portion 12 is formed. The cylindrical portion 12 has a threaded portion 12a formed on the outer peripheral surface of the upper end portion close to the lower surface of the head portion 11, and directly below the threaded portion 12a from the lower end on the front side and the rear side of the peripheral side wall of the cylindrical portion 12, respectively. Long and narrow cylindrical slits 12b and 12b are formed on the top and bottom.
上記液口栓１の筒部１２内には、防沫体２が挿入されて取り付けられる。防沫体２は、樹脂成製の防沫構造を備えた部品であり、防沫底板２１と一対の防沫縦板２２，２２と防沫天井板２３と防沫庇板２４と防沫屋根板２５とからなる各防沫板部によって構成されている。下端の防沫底板２１は、筒部１２の内筒に嵌合するほぼ水平な円板状の防沫板であり、図２に示すように、左右方向の両端部分が左右の外側を上方に向けて１０°程度傾斜させて形成されている。また、この防沫底板２１の左右の両端には爪２１ａ，２１ａが突設され、防沫体２を筒部１２内に挿入したときに係止部１２ｃ，１２ｃに係合させることにより、この防沫体２が下方に抜け落ちないように係止することができるようになっている。 A splash-proof body 2 is inserted and attached in the cylindrical portion 12 of the liquid stopper 1. The splash-proof body 2 is a component having a resin-made splash-proof structure, and includes a splash-proof bottom plate 21, a pair of splash-proof vertical plates 22, 22, a splash-proof ceiling plate 23, a splash-proof roof plate 24, and a splash-proof roof. It is comprised by each splash-proof board part which consists of the board 25. FIG. The splash-proof bottom plate 21 at the lower end is a substantially horizontal disc-shaped splash-proof plate that fits into the inner cylinder of the cylinder portion 12, and as shown in FIG. It is formed with an inclination of about 10 °. In addition, claws 21a and 21a project from the left and right ends of the splash-proof bottom plate 21, and when the splash-proof body 2 is inserted into the cylindrical portion 12, it is engaged with the locking portions 12c and 12c. The splash-proof body 2 can be locked so as not to fall down.
一対の防沫縦板２２，２２は、図３に示すように、防沫底板２１の上面から立設した垂直な壁板状の防沫板であり、この防沫体２を筒部１２内に挿入して取り付けたときに、前後方向に配置された一対の筒部スリット１２ｂ，１２ｂの間の空間の左右側を覆うように前後方向に沿って形成されている。また、各防沫縦板２２は、前後方向の中央部に形成された縦板スリット２２ａの間隙を開けて前後方向に２分割されると共に、これら２分割された前方側の壁板部が後方側の壁板部よりも板厚分だけ左側にずれて形成されている。なお、防沫体２は、このように前後方向に沿う防沫縦板２２，２２を有するので、樹脂成形の金型は前後方向に２分割された抜き型を用いる。ただし、各防沫縦板２２の縦板スリット２２ａを介した前方側と後方側の壁板部が面一で並んでいる場合には、この縦板スリット２２ａを形成するために左右方向の抜き型をさらに追加する必要がある。そこで、このように各防沫縦板２２の前方側と後方側の壁板部を少なくとも板厚分だけ左右にずらして形成することにより、前後方向に２分割された抜き型だけで樹脂成形が可能にしている。 As shown in FIG. 3, the pair of splash-proof vertical plates 22 and 22 are vertical wall-plate-like splash-proof plates erected from the upper surface of the splash-proof bottom plate 21. It is formed along the front-rear direction so as to cover the left and right sides of the space between the pair of cylindrical slits 12b, 12b disposed in the front-rear direction when being inserted and attached. Each splash-proof vertical plate 22 is divided into two in the front-rear direction by opening a gap between vertical plate slits 22a formed in the center portion in the front-rear direction, and the front-side wall plate portion divided into two is rearward. It is formed to be shifted to the left side by the thickness of the side wall plate portion. In addition, since the splash-proof body 2 has the splash-proof vertical plates 22 and 22 along the front-and-rear direction in this way, the die for resin molding uses a die that is divided into two in the front-and-rear direction. However, when the front and rear wall plates through the vertical plate slits 22a of each splash-proof vertical plate 22 are arranged flush with each other, the left and right direction punches are formed to form the vertical plate slits 22a. You need to add more types. Thus, by forming the front and rear wall plate portions of each splash-proof vertical plate 22 so as to be shifted to the left or right by at least the plate thickness, resin molding can be performed with only the die divided in the front-rear direction. Making it possible.
防沫天井板２３は、図４に示すように、左右一対の防沫縦板２２，２２の間（縦板スリット２２ａ，２２ａの間も含む）の上方を覆うほぼ水平な防沫板であり、図２に示すように、左右方向の中央を棟とした切り妻型の屋根のように１０°程度傾斜させている。即ち、この防沫天井板２３は、左右方向の中央を境としたこの左右両側部分が左右の外側を下方に向けて１０°程度傾斜している。また、この防沫天井板２３は、上面の前後左右方向の中央部から上方に向けて支持柱２６を突設している。 As shown in FIG. 4, the splash-proof ceiling plate 23 is a substantially horizontal splash-proof plate that covers the space between the pair of left and right splash-proof vertical plates 22 and 22 (including between the vertical plate slits 22 a and 22 a). As shown in FIG. 2, it is inclined about 10 ° like a gable roof with the center in the left-right direction as a ridge. That is, in the splash-proof ceiling plate 23, the left and right side portions with respect to the center in the left-right direction are inclined by about 10 ° with the left and right outer sides facing downward. Further, the splash-proof ceiling plate 23 has a support column 26 projecting upward from a central portion in the front / rear / right / left direction of the upper surface.
防沫庇板２４は、図５に示すように、上記防沫天井板２３の上方に配置された、筒部１２の内筒に嵌合するほぼ水平な円板状の防沫板であり、左右方向の中央部に形成された庇スリット２４ａの間隙を開けて左右方向に２分割され、上記支持柱２６の側面に一体成形や接着等によって繋がり支持されるようになっている。また、図２に示すように、これら２分割された防沫庇板２４の左右方向の両端部分は、左右の外側を上方に向けて１０°程度傾斜させて形成されている。庇スリット２４ａは、左右の幅が防沫天井板２３よりも十分に狭く形成されている。 As shown in FIG. 5, the splash-proof saddle plate 24 is a substantially horizontal disc-shaped splash-proof plate that is disposed above the splash-proof ceiling plate 23 and is fitted to the inner cylinder of the cylindrical portion 12. A gap is formed between the slits 24a formed in the central portion in the left-right direction and is divided into two in the left-right direction, and is connected to and supported by the side surface of the support pillar 26 by integral molding, adhesion, or the like. Further, as shown in FIG. 2, both end portions in the left-right direction of the two-split splash proof plate 24 are formed to be inclined about 10 ° with the left and right outer sides facing upward. The heel slit 24 a is formed so that the left and right widths are sufficiently narrower than the splash-proof ceiling plate 23.
防沫屋根板２５は、図１に示すように、上記防沫庇板２４の上方に配置された、筒部１２の内筒に嵌合するほぼ水平な円板の左右側の端部を切り落とした形状の防沫板であり、この防沫庇板２４の庇スリット２４ａの上方を左右にはみ出して確実に覆うものである。この防沫屋根板２５は、上記支持柱２６の上端面上に一体成形や接着等によって繋がり支持されるようになっている。また、この防沫屋根板２５の上面は、実際には周囲ほど下方に傾斜した曲面によって構成されている。 As shown in FIG. 1, the splash-proof roof plate 25 cuts off the left and right end portions of a substantially horizontal disk that is disposed above the splash-proof roof plate 24 and fits into the inner cylinder of the cylinder portion 12. The anti-splash plate has a shape that protrudes left and right and covers the upper side of the wrinkle slit 24a of the anti-splash plate 24. The splash-proof roof plate 25 is connected and supported on the upper end surface of the support column 26 by integral molding or adhesion. Moreover, the upper surface of this splash-proof roof board 25 is actually comprised by the curved surface which inclines below toward the periphery.
液口栓１の筒部１２内には、図２に示すように、上端部の奥に円盤状のフィルタ３が挿入され、この下方に上記防沫体２が挿入されて取り付けられる。そして、この液口栓１の筒部１２の上端部にリング状のパッキン４を外嵌し、鉛蓄電池の蓋板の注液口にこの筒部１２を挿入すると共に、この注液口のねじ孔にねじ部１２ａを螺着することにより装着される。 As shown in FIG. 2, a disc-like filter 3 is inserted into the back of the upper end portion, and the splash-proof body 2 is inserted and attached to the bottom of the tube portion 12 of the liquid spigot 1. Then, a ring-shaped packing 4 is externally fitted to the upper end portion of the cylindrical portion 12 of the liquid stopper 1, the cylindrical portion 12 is inserted into the liquid injection port of the lid plate of the lead storage battery, and the screw of the liquid injection port It is mounted by screwing the screw portion 12a into the hole.
上記構成によれば、鉛蓄電池が垂直方向や水平方向の強い振動を受けて電槽の各セル内に充填された電解液が飛沫となって垂直方向や水平方向に飛散した場合に、まず液口栓１の筒部１２の下端開口部から浸入しようとする飛沫は、防沫体２の防沫底板２１によって遮られる。従って、この飛沫は、前後に飛散する方向成分を有するものだけが、筒部１２の筒部スリット１２ｂ，１２ｂを通り抜けて、防沫体２の防沫縦板２２，２２の間の空間に入り込むことになる。しかしながら、このようにして入り込んだ飛沫は、左右に飛散する方向成分を有するものの一部だけしか、縦板スリット２２ａを通り抜けて防沫縦板２２，２２の左右側の空間に入り込むことができず、これら防沫縦板２２，２２や防沫天井板２３に遮られた飛沫は、防沫底板２１の上面から筒部スリット１２ｂ，１２ｂの下端部を通って再びセル内に戻される。また、防沫縦板２２，２２の左右側の空間に入り込んだ飛沫は、上方に飛散しても防沫庇板２４に遮られるので、防沫縦板２２，２２よりも左右外側の防沫底板２１上の傾斜面に沿って再び縦板スリット２２ａ，２２ａを通りセル内に戻される。そして、防沫庇板２４に遮られることなく庇スリット２４ａを通り抜けてさらに上方に達した飛沫も、防沫屋根板２５に遮られて防沫天井板２３上に落下し、屋根状の傾斜に沿って下方に流れて再びセル内に戻される。従って、本実施形態の液口栓１を用いると、筒部１２内に水平や垂直のあらゆる飛散方向成分を有する電解液の飛沫が浸入しても、防沫体２を通り抜けることができないために、さらに上方のフィルタ３を介し排気孔１１ｂから外部に溢液するおそれがなくなり、振動溢液性能を向上させることができる。 According to the above configuration, when the lead storage battery is subjected to strong vertical or horizontal vibration and the electrolyte filled in each cell of the battery case is splashed and splashed in the vertical or horizontal direction, Splashes entering from the lower end opening of the cylindrical portion 12 of the plug 1 are blocked by the splash-proof bottom plate 21 of the splash-proof body 2. Accordingly, only the splash having a directional component that scatters back and forth passes through the cylindrical slits 12b and 12b of the cylindrical portion 12 and enters the space between the splash-proof vertical plates 22 and 22 of the splash-proof body 2. It will be. However, only a part of the splash that has entered in the right and left direction can pass through the vertical plate slit 22a and enter the space on the left and right sides of the splash-proof vertical plates 22 and 22. The splashes blocked by the splash-proof vertical plates 22 and 22 and the splash-proof ceiling plate 23 are returned to the cell again from the upper surface of the splash-proof bottom plate 21 through the lower ends of the cylindrical slits 12b and 12b. Also, splash entering into the left and right side spaces of the splash-proof vertical plates 22 and 22, since even scattered upward is blocked by the splash-proof eave plate 24, the right and left outer side than the splash-proof vertical plate 22 and 22 splash proof Along the inclined surface on the bottom plate 21, it passes through the vertical plate slits 22a and 22a again and is returned into the cell. Then, the splash that has passed through the heel slit 24a without being blocked by the splash proof board 24 and further reaches the upper side is also blocked by the splash proof roof board 25 and falls onto the splash proof ceiling board 23, resulting in a roof-like slope. And flow back down into the cell. Therefore, when the liquid spigot 1 according to the present embodiment is used, even if the electrolyte solution having any horizontal or vertical scattering direction component enters the cylindrical portion 12, it cannot pass through the splash-proof body 2. Further, there is no risk of overflowing from the exhaust hole 11b to the outside via the upper filter 3, and the vibration overflow performance can be improved.
しかも、半円状の大きく傾斜した水平防沫板を上下に複数段配置するのではなく、中央部に庇スリット２４ａを形成した防沫庇板２４の上下に僅かな間隔で防沫天井板２３と防沫屋根板２５を配置するので、液口栓１の筒部１２の長さを短くして鉛蓄電池の高エネルギー密度化を図ることができるだけでなく、筒部スリット１２ｂ，１２ｂの上端をねじ部１２ａの付け根までできるだけ高くすることができるようになり、充電により電解液の液位が上昇しても、これらの筒部スリット１２ｂ，１２ｂが電解液に完全に浸かるようなこともなくなる。従って、このような液位上昇時にも、セル内で発生したガスは、筒部スリット１２ｂ，１２ｂから筒部１２内に入り込み防沫体２の各スリット２２ａ，２４ａを通り抜けて、フィルタ３を介し排気孔１１ｂから確実に外部に排出することができるので、静的溢液性能も向上させることができる。 In addition, the semi-circular large inclined horizontal splash-proof plates are not arranged in a plurality of stages up and down, but the splash-proof ceiling plate 23 at a slight interval above and below the splash-proof plate 24 having the vertical slit 24a formed in the center. And the splash-proof roof plate 25 are arranged, so that not only can the length of the cylindrical portion 12 of the liquid spigot 1 be shortened to increase the energy density of the lead storage battery, but also the upper ends of the cylindrical portion slits 12b and 12b It becomes possible to make it as high as possible to the root of the screw part 12a, and even if the liquid level of the electrolyte rises due to charging, the cylindrical slits 12b and 12b are not completely immersed in the electrolyte. Therefore, even when the liquid level rises, the gas generated in the cell enters the cylindrical portion 12 from the cylindrical slits 12b and 12b, passes through the slits 22a and 24a of the splash-proof body 2, and passes through the filter 3. Since it can discharge | emit reliably outside from the exhaust hole 11b, static overflow performance can also be improved.
なお、上記実施形態では、特に筒部１２の短いことが要求されるトップフラットタイプの鉛蓄電池について説明したが、頭部１１が蓋板の上面から突出する通常の鉛蓄電池の液口栓１にも同様に実施可能である。また、上記実施形態では、液口栓１にフィルタ３を取り付けた場合を示したが、フィルタ３を用いない液口栓１にも同様に実施可能である。 In addition, in the said embodiment, although the top flat type lead acid battery in which the short cylinder part 12 was requested | required especially was demonstrated, the head 11 protrudes from the liquid mouth plug 1 of the normal lead acid battery which protrudes from the upper surface of a cover plate. Can be similarly implemented. Moreover, although the case where the filter 3 was attached to the liquid spigot 1 was shown in the said embodiment, it can implement similarly to the liquid spigot 1 which does not use the filter 3. FIG.
また、上記実施形態では、防沫体２の上端に防沫屋根板２５を配置する場合を示したが、この防沫屋根板２５を配置しない場合にも、ほぼ同等の耐溢液性能を確保することはできる。ただし、より一層の耐溢液性能を得るためには、上記実施形態の防沫屋根板２５の上方にさらに防沫庇板と防沫屋根板の組を複数段にわたって配置することも可能であり、これらの防沫板はいずれも支持柱２６によって支持させることができる。 Moreover, in the said embodiment, although the case where the splash-proof roofing board 25 was arrange | positioned at the upper end of the splash-proof body 2 was shown, also when this splash-proofing roofing board 25 is not arrange | positioned, substantially equivalent overflow resistance performance is ensured. Can do. However, in order to obtain a further overflow resistance, it is also possible to dispose a plurality of sets of splash-proof slats and splash-proof roof boards over the splash-proof roof board 25 of the above embodiment over a plurality of stages. Any of these splash-proof plates can be supported by the support column 26.
また、上記実施形態では、防沫底板２１と防沫天井板２３と防沫庇板２４に１０°程度の傾斜を設ける場合を示したが、この傾斜角度は任意であり、傾斜を設けない場合であっても、電解液の飛沫を円滑にセルに戻す機能は多少劣るものの、耐溢液性能については同等のものを得ることができる。 Moreover, in the said embodiment, although the case where the inclination of about 10 degrees was provided in the splash-proof bottom board 21, the splash-proof ceiling board 23, and the splash-proof saddle board 24 was shown, this inclination angle is arbitrary and does not provide an inclination. Even so, although the function of smoothly returning the droplets of the electrolytic solution to the cell is somewhat inferior, the equivalent anti-overflow performance can be obtained.
また、上記実施形態では、防沫縦板２２，２２にずれを設ける場合を示したが、防沫体２の成形加工に支障が生じなければ、このようなずれはなくてもよい。さらに、上記実施形態では、液口栓１の筒部１２内に防沫体２を挿入することにより各防沫板を配置する場合を示したが、これらの防沫板の配置手段は任意である。 In the above embodiment, although the case where the deviation in the splash-proof vertical plates 22 and 22, unless create an obstacle to the molding of Boawatai 2, may be no such deviation. Furthermore, in the said embodiment, although the case where each splash-proof board was arrange | positioned by inserting the splash-proof body 2 in the cylinder part 12 of the liquid spigot 1 was shown, the arrangement | positioning means of these splash-proof boards is arbitrary. is there.
また、上記実施形態では、自動車用の鉛蓄電池について示したが、この蓄電池の用途や種類も上記実施形態に限定されることはない。 Moreover, in the said embodiment, although it showed about the lead acid battery for motor vehicles, the use and kind of this storage battery are not limited to the said embodiment.
上記実施形態で示した液口栓１と従来例の液口栓をそれぞれ鉛蓄電池に用いて振動溢液性能を比較した結果を表１に示す。ここで、電解液の液位は、電槽のアッパーレベルに合わせた。そして、鉛蓄電池には、上下方向と水平方向における電槽の短軸方向と長軸方向にそれぞれ振動を加えた。これらの各振動は、それぞれ１０Ｈｚで５分間加え、また、強さを０．５Ｇから始めて０．５Ｇずつ上げ、それぞれの強さについて試験した。さらに、溢液の有無を明確にするために、液口栓１はフィルタ３を取り付けない状態で使用した。 Table 1 shows the results of comparison of vibration overflow performance using the liquid spigot 1 shown in the above embodiment and the liquid spigot of the conventional example in a lead storage battery, respectively. Here, the liquid level of the electrolyte was adjusted to the upper level of the battery case. The lead storage battery was subjected to vibrations in the short axis direction and the long axis direction of the battery case in the vertical and horizontal directions, respectively. Each of these vibrations was applied at 10 Hz for 5 minutes, and the strength was tested by starting with 0.5G and increasing by 0.5G. Furthermore, in order to clarify the presence or absence of overflow, the liquid spigot 1 was used without the filter 3 attached.
この比較結果によれば、上下方向の振動に対する耐溢液性能はほぼ同等であるが、水平方向では実施例の液口栓１を用いた場合の方が優れた耐溢液性能を示し、特に電槽の短軸方向の振動を加えた場合には、従来例よりも遥かに高い耐溢液性能を示すことが分かった。 According to this comparison result, the anti-overflow performance against vibration in the vertical direction is almost the same, but in the horizontal direction, the anti-overflow performance is better when the liquid stopper 1 of the embodiment is used. When vibration in the minor axis direction of the battery case was applied, it was found that the overflow resistance performance was much higher than that of the conventional example.
また、上記実施形態で示した液口栓１と従来例の液口栓をそれぞれ鉛蓄電池に用いて静的溢液性能を比較した結果を表２に示す。ここで、電解液の液位は、電槽のアッパーレベルに合わせた場合（ＵＬ）と、これより５ｍｍ高い場合（ＵＬ＋５ｍｍ）と、これより１０ｍｍ高い場合（ＵＬ＋１０ｍｍ）とを比較した。そして、充電電流も、１０Ａと２０Ａと４０Ａの場合について、それぞれ２時間の充電を行って比較した。 Table 2 shows the result of comparing the static overflow performance using the liquid spigot 1 shown in the above embodiment and the liquid spigot of the conventional example in a lead storage battery. Here, the case where the level of the electrolyte was adjusted to the upper level of the battery case (UL), the case where it was 5 mm higher (UL + 5 mm), and the case where it was 10 mm higher (UL + 10 mm) were compared. The charging currents were also compared for 10 A, 20 A, and 40 A by charging for 2 hours.
この比較結果によれば、液位がアッパーレベルよりも１０ｍｍ高い異常な場合には、いずれも１０Ａの充電時に溢液が発生したが、それよりも低い液位では、従来例がどちらも溢液を生じたのに対して、実施例の液口栓１を用いた場合には、充電電流を大きくしても溢液が生じないようになることが分かった。 According to this comparison result, in the case where the liquid level was abnormal 10 mm higher than the upper level, overflow occurred at the time of charging at 10A. However, at the liquid level lower than that, both of the conventional examples overflowed. On the other hand, it was found that when the liquid spout 1 of the example was used, overflow did not occur even when the charging current was increased.
