Description

鉛蓄電池と、鉛蓄電池と排気ホースとの連結体Lead-acid battery and connected body of lead-acid battery and exhaust hose

　本発明は、排気経路が内部に設けられた隆起部を含む蓋を有する鉛蓄電池、およびその鉛蓄電池と排気ホースとの連結体に関する。 The present invention relates to a lead storage battery having a lid including a raised portion in which an exhaust path is provided, and a connected body of the lead storage battery and an exhaust hose.

　近年、複数のセル室と連通した排気経路が設けられた蓋を有する鉛蓄電池が、自動車のエンジン始動用に多く用いられている。この形状の鉛蓄電池では、排気経路の排出口を排気ホースと繋ぐ必要がある。 In recent years, lead storage batteries having a lid provided with an exhaust path communicating with a plurality of cell chambers are often used for starting an engine of an automobile. In the lead storage battery having this shape, it is necessary to connect the exhaust port of the exhaust path to the exhaust hose.

　ところで一般に、自動車の寿命を終えるまでの間に、搭載された鉛蓄電池は、車検など整備やユーザー変更の際に交換される。交換の際には、自動車の部品の一つである排気ホースが古い鉛蓄電池から外され、新たな鉛蓄電池に繋げられる。 By the way, in general, the lead-acid battery installed in the vehicle will be replaced when the vehicle is inspected or changed by the user until the end of the life of the vehicle. At the time of replacement, the exhaust hose, which is one of the parts of the automobile, is removed from the old lead storage battery and connected to a new lead storage battery.

　また、この形状の鉛蓄電池は、搭載される車種によって、両端の排出口のうち使用しない方を封口する必要がある。従来は使用しない方の排出口を、予め製造会社が超音波溶着などで封口している。しかしながら、このやり方では使用者（購入者）が自身の車の仕様（どちらの排出口を使用するのか）を熟知していないと、誤って使用する排出口が封口されている鉛蓄電池を購入してしまう虞がある。 Also, this type of lead-acid battery needs to seal the unused one of the outlets at both ends depending on the type of vehicle installed. Conventionally, a manufacturing company seals a discharge port that is not used in advance by ultrasonic welding or the like. However, in this method, if the user (buyer) is not familiar with the specifications of his car (which outlet is used), he / she purchases a lead-acid battery with the outlet used accidentally sealed. There is a risk that.

　そこで、蓋の両端に排気口を設け、そのうちの一方を封口する栓を同梱して鉛蓄電池を販売するやり方が好ましいと考えられる。この場合、使用者は購入後に自身の車の仕様を把握してから、特許文献１のようにネジ部を有する栓で、封口すべき側の排出口を封口することができる。 Therefore, it is considered preferable to sell lead-acid batteries by providing exhaust ports at both ends of the lid and enclosing a plug for sealing one of them. In this case, after the user grasps the specifications of his / her car after purchase, the user can seal the discharge port on the side to be sealed with a plug having a screw portion as in Patent Document 1.

　以上、図面を参照しながら本発明の好適な実施の形態について説明する。なお本発明は以下の説明内容に限定されない。 The preferred embodiments of the present invention are described above with reference to the drawings. The present invention is not limited to the following description.

　（実施の形態１）
　本発明の実施の形態１の説明に先立ち、従来の構成における問題点を簡単に説明する。特許文献１に開示されたネジ構造を排気ホースと排出口とに適用して連結した場合でも、螺合の際に細長い排気ホースを回転させることは、狭い格納スペースでは困難な場合がある。また、排気ホースの構造を改良して螺合しやすくしたとしても、排気ホースと排出口との脱着を繰り返すと、排気ホースや排出口のネジ山が破損して、鉛蓄電池を交換した後の嵌合状態が安定しない虞がある。 (Embodiment 1)
Prior to the description of the first embodiment of the present invention, problems in the conventional configuration will be briefly described. Even when the screw structure disclosed in Patent Document 1 is applied to and connected to the exhaust hose and the discharge port, it may be difficult to rotate the elongated exhaust hose during screwing in a narrow storage space. In addition, even if the exhaust hose structure is improved to facilitate screwing, if the exhaust hose and the exhaust port are repeatedly attached and detached, the exhaust hose and the screw thread of the exhaust port will be damaged and the lead storage battery will be replaced. There is a possibility that the fitting state is not stable.

　以下、本発明の実施の形態１について、図面を参照しながら説明する。図１は、本実施の形態による連結体に用いられる鉛蓄電池を模式的に示した部分透視図である。図２は本実施の形態による連結体を模式的に示した部分透視図である。 Hereinafter, Embodiment 1 of the present invention will be described with reference to the drawings. FIG. 1 is a partial perspective view schematically showing a lead-acid battery used in the connector according to the present embodiment. FIG. 2 is a partial perspective view schematically showing the connector according to the present embodiment.

　図１に示すように、鉛蓄電池２０は、複数の極板群１と、樹脂製の電槽２と、樹脂製の蓋４とを有する。極板群１はそれぞれ、正極と、負極と、正極と負極との間に介在するセパレータとを有する。電槽２は、極板群１のそれぞれを挿入する複数のセル室２Ａを有する。蓋４は、第一端に、円筒状に窪んだ排出口３Ａを有するともに、複数のセル室２Ａと連通した排気経路３が内部に設けられ、電槽２の開口部を封口している。そして、図２に示すように、排気経路３の排出口３Ａを排気ホース５と繋ぐことで、鉛蓄電池２０と排気ホース５との連結体が構成される。すなわち、排気ホース５は、排気経路３の排出口３Ａで蓋４に連結される。なお、排気経路３は隆起部４Ａの内部に設けられている。 As shown in FIG. 1, the lead storage battery 20 has a plurality of electrode plate groups 1, a resin battery case 2, and a resin lid 4. Each of the electrode plate groups 1 has a positive electrode, a negative electrode, and a separator interposed between the positive electrode and the negative electrode. The battery case 2 has a plurality of cell chambers 2A into which each of the electrode plate groups 1 is inserted. The lid 4 has a discharge port 3 </ b> A that is recessed in a cylindrical shape at a first end, and an exhaust path 3 that communicates with the plurality of cell chambers 2 </ b> A is provided inside to seal the opening of the battery case 2. And as shown in FIG. 2, the connection body of the lead storage battery 20 and the exhaust hose 5 is comprised by connecting the discharge port 3A of the exhaust path 3 with the exhaust hose 5. FIG. That is, the exhaust hose 5 is connected to the lid 4 at the exhaust port 3 </ b> A of the exhaust path 3. The exhaust path 3 is provided inside the raised portion 4A.

　図３Ａ、図３Ｂは排気ホース５の要部の例を示す模式図である。排気ホース５は、内部に空洞が設けられた円筒状の先端部５Ａと、内部に、先端部５Ａの空洞と連なる空洞が設けられたチューブ部５Ｃとを有する。先端部５Ａには、その一部を周回するように連続したリブ５Ｂが設けられている。先端部５Ａとチューブ部５Ｃとの境界は、リブ５Ｂと離間している。先端部５Ａを鉛蓄電池２０の排出口３Ａに挿入することで、図２に示す形態となる。 FIG. 3A and FIG. 3B are schematic views showing an example of a main part of the exhaust hose 5. The exhaust hose 5 has a cylindrical tip portion 5A provided with a cavity therein, and a tube portion 5C provided therein with a cavity continuous with the cavity of the tip portion 5A. The leading end 5A is provided with a continuous rib 5B so as to go around a part thereof. The boundary between the tip portion 5A and the tube portion 5C is separated from the rib 5B. By inserting the distal end portion 5A into the discharge port 3A of the lead storage battery 20, the form shown in FIG.

　図４は図２に示す連結体の要部断面図である。排出口３Ａの内径Ａ、先端部５Ａにおけるリブ５Ｂ以外の部分の外径Ｂ、リブ５Ｂの外径Ｃ、チューブ部５Ｃの外径Ｄは、Ｂ＜Ａ＜Ｃ＜Ｄの関係を満たしている。 FIG. 4 is a cross-sectional view of the main part of the connector shown in FIG. The inner diameter A of the discharge port 3A, the outer diameter B of the tip 5A other than the rib 5B, the outer diameter C of the rib 5B, and the outer diameter D of the tube portion 5C satisfy the relationship B <A <C <D. .

　前述のように、一般に、自動車の寿命を終えるまでの間に、搭載された鉛蓄電池は、車検など整備やユーザー変更の際に交換される。交換の際には、自動車の部品の一つである排気ホースが古い鉛蓄電池から外され、新たな鉛蓄電池に繋げられる。すなわち図２のような連結体として鉛蓄電池２０を搭載する一般的な自動車では、排気ホース５と鉛蓄電池２０の排気経路３（排出口３Ａ）とを脱着する必要がある。そのため、脱着した後の排気ホース５と鉛蓄電池２０の排気経路３（排出口３Ａ）との嵌合状態を良好に保つ必要がある。 As mentioned above, in general, the lead-acid battery installed in the vehicle is replaced during maintenance or user changes such as vehicle inspections until the end of the life of the vehicle. At the time of replacement, the exhaust hose, which is one of the parts of the automobile, is removed from the old lead storage battery and connected to a new lead storage battery. That is, in a general automobile in which the lead storage battery 20 is mounted as a connector as shown in FIG. 2, it is necessary to detach the exhaust hose 5 and the exhaust path 3 (discharge port 3 </ b> A) of the lead storage battery 20. Therefore, it is necessary to keep the fitting state of the exhaust hose 5 after desorption and the exhaust path 3 (exhaust port 3A) of the lead storage battery 20 favorable.

　本発明の形態では、以下に示すように、作業性に優れかつ脱着後も嵌合状態を保てる構成で、鉛蓄電池２０と排気ホース５とを連結することができる。 In the embodiment of the present invention, as shown below, the lead storage battery 20 and the exhaust hose 5 can be connected with a configuration that is excellent in workability and can maintain a fitted state even after desorption.

　前述のように、排出口３Ａの内径Ａよりも先端部５Ａの外径Ｂが小さい。そのため、排出口３Ａに無理なく先端部５Ａを挿入できる。但し、リブ５Ｂの外径Ｃは排出口３Ａの内径Ａよりも大きいので、リブ５Ｂは、隙間を生じさせることなく排出口３Ａの内壁面に嵌合される。 As described above, the outer diameter B of the tip 5A is smaller than the inner diameter A of the discharge port 3A. Therefore, the tip 5A can be inserted into the discharge port 3A without difficulty. However, since the outer diameter C of the rib 5B is larger than the inner diameter A of the discharge port 3A, the rib 5B is fitted to the inner wall surface of the discharge port 3A without causing a gap.

　先端部５Ａの全長αに対するリブ５Ｂの１つ当たりの長さβの比β／αは、０．０３以上、０．２５以下であることが好ましい。比β／αが０．０３未満だと、リブ５Ｂの面積比が極端に小さくなるために、リブ５Ｂの剛性が相対的に過度に下降する。一方で比β／αが０．２５を超えると、リブ５Ｂの面積比が極端に大きくなるために、リブ５Ｂの剛性が相対的に過度に上昇する。これらのいずれの場合であっても、脱着した後の排気ホース５と排出口３Ａとの嵌合状態が良好に保てなくなる場合がありえる。この比β／αの適正範囲については、後述する例で具体的に説明する。 The ratio β / α of the length β per rib 5B to the total length α of the tip 5A is preferably 0.03 or more and 0.25 or less. If the ratio β / α is less than 0.03, the area ratio of the ribs 5B becomes extremely small, so that the rigidity of the ribs 5B decreases relatively excessively. On the other hand, if the ratio β / α exceeds 0.25, the area ratio of the ribs 5B becomes extremely large, so that the rigidity of the ribs 5B increases relatively excessively. In any of these cases, the fitting state between the exhaust hose 5 and the discharge port 3A after being detached may not be maintained well. The appropriate range of the ratio β / α will be specifically described in an example described later.

　なお蓋４、排気ホース５ともに樹脂製（樹脂成型品）である。そのため、排出口３Ａ、先端部５Ａともに断面を真円とすることは困難であり、断面は僅かに歪んだ楕円となることが多い。しかしながら、先端部５Ａの内部は空洞（排気経路３と連通したガス排出ルートの一部）であるので、先端部５Ａは、それ自身あるいは排出口３Ａの歪みを吸収するように容易に変形できる。この変形により、排出口３Ａと排気ホース５とは水密に結合し、密閉性を保つことができる。なお先端部５Ａの肉厚が先端部５Ａの外径に対して５％以上、２５％以下、より好ましくは８％以上、１５％以下であると、歪みを吸収するために先端部５Ａが容易に変形できるので好ましい。 The lid 4 and the exhaust hose 5 are both made of resin (resin molded product). For this reason, it is difficult to make the cross section of the discharge port 3A and the front end portion 5A into a perfect circle, and the cross section is often an ellipse that is slightly distorted. However, since the inside of the tip portion 5A is a cavity (a part of the gas discharge route communicating with the exhaust path 3), the tip portion 5A can be easily deformed so as to absorb the distortion of itself or the discharge port 3A. Due to this deformation, the discharge port 3A and the exhaust hose 5 can be joined in a watertight manner, and the sealing property can be maintained. If the thickness of the tip portion 5A is 5% or more and 25% or less, more preferably 8% or more and 15% or less with respect to the outer diameter of the tip portion 5A, the tip portion 5A is easy to absorb distortion. It is preferable because it can be transformed into

　排出口３Ａの内径Ａよりも大きい外径Ｃを有するリブ５Ｂを無理なく排出口３Ａに取り付けるために、リブ５Ｂの形状は、少なくとも挿入方向に向かって外径Ｃが徐々に小さくなるようにすることが好ましい。この条件を満たすリブ５Ｂの形態は、図５Ａ～図５Ｅに示すように、種々挙げることができる。図５Ａ～図５Ｅは排気ホース５と、リブ５Ｂとの断面のバリエーションを示している。なお、リブ５Ｂとは先端部５Ａにおいて他の部分よりも外径が大きくなっている全ての箇所を指す。そして、リブ５Ｂの１つ当たりの長さとはβで示される長さを指す。リブ５Ｂの外径Ｃとはその中で最も外径が大きい箇所の寸法を指す。 In order to easily attach the rib 5B having the outer diameter C larger than the inner diameter A of the discharge port 3A to the discharge port 3A, the shape of the rib 5B is such that the outer diameter C gradually decreases at least in the insertion direction. It is preferable. As shown in FIGS. 5A to 5E, various forms of the rib 5B satisfying this condition can be cited. FIG. 5A to FIG. 5E show variations of cross sections of the exhaust hose 5 and the rib 5B. The rib 5B refers to all locations where the outer diameter of the tip 5A is larger than other portions. The length per rib 5B indicates the length indicated by β. The outer diameter C of the rib 5B refers to the dimension of the portion having the largest outer diameter.

　さらに、チューブ部５Ｃの外径Ｄは、リブ５Ｂの外径Ｃよりも大きい。そして、先端部５Ａとチューブ部５Ｃとの境界はリブ５Ｂと離間している。排気ホース５は、少なくとも１回、排気経路３（排出口３Ａ）からとり外されることが想定される。具体的には、排気ホース５における先端部５Ａとチューブ部５Ｃとの境界と蓋４との間に精密ドライバーなど先端が鋭利な治具を差し込むことで、使用者は排気ホース５を容易に外すことができる。 Furthermore, the outer diameter D of the tube portion 5C is larger than the outer diameter C of the rib 5B. The boundary between the tip 5A and the tube 5C is separated from the rib 5B. It is assumed that the exhaust hose 5 is removed from the exhaust path 3 (exhaust port 3A) at least once. Specifically, the user can easily remove the exhaust hose 5 by inserting a jig with a sharp tip such as a precision screwdriver between the lid 4 and the boundary between the tip 5A and the tube 5C in the exhaust hose 5. be able to.

　もし先端部５Ａとチューブ部５Ｃとの境界がリブ５Ｂと密接していると、先端が鋭利な治具を差し込んで排気ホース５を取り外す際に治具の先端がリブ５Ｂを傷つけてしまう虞がある。このようにリブ５Ｂが傷つくと、その後の取り付けにおいて嵌合状態が低下する。したがって先端部５Ａとチューブ部５Ｃとの境界はリブ５Ｂと離間している。また先端部５Ａとチューブ部５Ｃとの境界がリブ５Ｂと離間していることで、使用者は、リブ５Ｂが排出口３Ａの内壁を摩擦しながら通過する感覚の後に、先端部５Ａとチューブ部５Ｃとの境界が蓋４に衝突する感覚を得る。そのため、使用者は、先端部５Ａが排気経路３に確実に挿入されたことを体感できる。したがって、使用者が中途半端な挿入状態で作業を終えることがなくなる。上述の効果を確実に得るためには、先端部５Ａとチューブ部５Ｃとの境界はリブ５Ｂから０．５ｍｍ以上離間していることが好ましい。 If the boundary between the tip portion 5A and the tube portion 5C is in close contact with the rib 5B, when the jig with a sharp tip is inserted and the exhaust hose 5 is removed, the tip of the jig may damage the rib 5B. is there. Thus, when the rib 5B is damaged, a fitting state will fall in subsequent attachment. Therefore, the boundary between the tip portion 5A and the tube portion 5C is separated from the rib 5B. Further, since the boundary between the tip portion 5A and the tube portion 5C is separated from the rib 5B, the user can feel that the rib 5B passes through the inner wall of the discharge port 3A while rubbing, and then the tip portion 5A and the tube portion. A feeling that the boundary with 5C collides with the lid 4 is obtained. Therefore, the user can experience that the distal end portion 5 </ b> A has been reliably inserted into the exhaust path 3. Therefore, the user does not finish the work in the halfway insertion state. In order to reliably obtain the above-described effect, it is preferable that the boundary between the tip portion 5A and the tube portion 5C be separated from the rib 5B by 0.5 mm or more.

　また、排気ホース５に、先端部５Ａの延伸方向に互いに離間したリブ５Ｂが２つあれば、リブ５Ｂのうち１つが破損しても、もう１つのリブ５Ｂによって良好な嵌合状態が保たれるので好ましい。また上述したように、排気ホース５は樹脂成型品であるため、対称形に成形されない場合がある。図６Ａ、図６Ｂはその一例として、リブ５Ｂが非対称である排気ホース５を用いた場合を示している。このような場合でも、図６Ａに示すようにリブ５Ｂが２つ設けられた排気ホース５は、排出口３Ａに偏心した形で挿入されても、２つのリブ５Ｂともに排出口３Ａに密着できるので良好な嵌合状態が保たれる。しかしながら、図６Ｂに示すように、リブ５Ｂが３つ設けられた排気ホース５が排出口３Ａに偏心した形で挿入されると、点線矢印で示した経路の隙間が生じてしまう虞がある。よって、２つのリブ５Ｂが設けられた排気ホース５が、種々のケースにおいて良好な嵌合状態を保てる最善の形状を有する。したがって、リブ５Ｂは１つまたは２つ設けられていることが好ましい。 Further, if the exhaust hose 5 has two ribs 5B that are separated from each other in the extending direction of the front end portion 5A, even if one of the ribs 5B breaks, the other rib 5B maintains a good fitting state. This is preferable. Moreover, since the exhaust hose 5 is a resin molded product as described above, it may not be formed symmetrically. 6A and 6B show a case where the exhaust hose 5 having the asymmetric rib 5B is used as an example. Even in such a case, even if the exhaust hose 5 provided with two ribs 5B as shown in FIG. 6A is inserted eccentrically into the discharge port 3A, both the ribs 5B can be in close contact with the discharge port 3A. A good fitting state is maintained. However, as shown in FIG. 6B, when the exhaust hose 5 provided with the three ribs 5B is inserted in an eccentric manner in the discharge port 3A, there is a possibility that a gap in the path indicated by the dotted arrow is generated. Therefore, the exhaust hose 5 provided with the two ribs 5B has the best shape that can maintain a good fitting state in various cases. Therefore, it is preferable that one or two ribs 5B are provided.

　以下、具体的な例を挙げて、先端部５Ａの全長αに対するリブ５Ｂの１つ当たりの長さβの比β／αの適正範囲について説明する。なお後述する評価では、実電池ではなくモデルを用いている。以下、図７を参照しながら説明する。図７は、本実施の形態による連結体の評価方法を示す図である。 Hereinafter, an appropriate range of the ratio β / α of the length β per rib 5B with respect to the total length α of the tip portion 5A will be described by giving a specific example. In the evaluation described later, a model is used instead of an actual battery. Hereinafter, a description will be given with reference to FIG. FIG. 7 is a diagram showing a method for evaluating a linked body according to the present embodiment.

　まず、欧州規格ＢＳ　ＥＮ５０３４２－２：２００７においてＬＮ３型バッテリーと定義される鉛蓄電池（２０時間率容量７５Ａｈ）の電槽２と蓋４のみを用意する。電槽２には極板群１や電解液は収納せずに、電槽２の開口部を蓋４で封口し、鉛蓄電池のモデルを作製している。蓋４には、複数のセル室２Ａと連通する排気経路３が設けられている。なお、排出口３Ａの外径Ａは５．８５ｍｍである。 First, only the battery case 2 and the lid 4 of the lead storage battery (20 hour rate capacity 75 Ah) defined as the LN3 type battery in the European standard BS EN 50342-2: 2007 are prepared. The battery case 2 does not store the electrode plate group 1 or the electrolytic solution, and the opening part of the battery case 2 is sealed with a lid 4 to produce a lead-acid battery model. The lid 4 is provided with an exhaust path 3 communicating with the plurality of cell chambers 2A. The outer diameter A of the discharge port 3A is 5.85 mm.

　そして、排出口３Ａに、先端部５Ａ、リブ５Ｂおよびチューブ部５Ｃが図５Ａに示す形状を有する排気ホース５を挿入する。先端部５Ａの全長は１０ｍｍ、外径Ｂは５．７８ｍｍである。リブ５Ｂの外径Ｃは５．９５ｍｍ、長さは（表１）に示すように試験体ごとに異なっている。チューブ部５Ｃの外径Ｄは７．３２ｍｍである。さらに先端部５Ａの肉厚は、０．７７ｍであり、この寸法は、先端部５Ａの外径に対して１３．３％である。また先端部５Ａとチューブ部５Ｃとの境界は、チューブ部５Ｃに近い方のリブ５Ｂから２．０ｍｍ離間している。 Then, the exhaust hose 5 having the tip 5A, the rib 5B, and the tube 5C having the shape shown in FIG. 5A is inserted into the discharge port 3A. The total length of the tip 5A is 10 mm, and the outer diameter B is 5.78 mm. The outer diameter C of the rib 5B is 5.95 mm, and the length is different for each specimen as shown in (Table 1). The outer diameter D of the tube portion 5C is 7.32 mm. Furthermore, the thickness of the tip portion 5A is 0.77 m, and this dimension is 13.3% with respect to the outer diameter of the tip portion 5A. The boundary between the tip 5A and the tube 5C is 2.0 mm away from the rib 5B closer to the tube 5C.

　一方、蓋４の上面から排気経路３に通じるように穴を開け、流量計８が途中に設けられた注入ホース９をこの穴に挿入し、エポキシ樹脂で挿入箇所を密閉している。この状態でモデルを容器６に収納し、液面７が蓋４の上面よりも高くなるように水を注いでモデルを水没させる。そして、流量計８の値が１０Ｌ／分を示すようにエアーを注入ホース９からモデルに注入し、矢印の方向に１分間エアーを流す。１０Ｌ／分という値は、自動車のオルタネータが故障して１５０Ａ相当の過電流が鉛蓄電池に流れ、全ての過電流が電解液（水）の電気分解に費やされたと仮定した場合の値である。もし排気ホース５と排出口３Ａとの嵌合状態が適切でなければ、連結箇所１０から水泡が発生する。 On the other hand, a hole is opened from the upper surface of the lid 4 to the exhaust path 3, an injection hose 9 provided with a flow meter 8 is inserted into this hole, and the insertion point is sealed with epoxy resin. In this state, the model is stored in the container 6, and water is poured so that the liquid level 7 is higher than the upper surface of the lid 4 to submerge the model. Then, air is injected from the injection hose 9 into the model so that the value of the flow meter 8 indicates 10 L / min, and air is allowed to flow in the direction of the arrow for 1 minute. The value of 10 L / min is a value when it is assumed that the alternator of the automobile has failed and an overcurrent equivalent to 150 A flows to the lead-acid battery, and that all the overcurrent is spent on the electrolysis of the electrolyte (water). . If the fitting state between the exhaust hose 5 and the discharge port 3A is not appropriate, water bubbles are generated from the connecting portion 10.

　さらにこのモデルを水中から取り出し、排気ホース５の取り外しと取り付け（脱着）を行ってから再び水中に投入し、上述の条件でエアーを流す。この作業を合計５回繰り返し、脱着を行う前、脱着を３回行った後、および脱着を５回行った後における水泡の発生の有無を観察している。その結果を（表１）に示す。 Furthermore, this model is taken out from the water, the exhaust hose 5 is removed and attached (removed), and then it is thrown into the water again. This operation is repeated a total of 5 times, and the presence or absence of water bubbles is observed before and after desorption, after 3 desorptions, and after 5 desorptions. The results are shown in (Table 1).

Figure JPOXMLDOC01-appb-T000001

　排気ホース５の脱着を行う前には、いずれの試験体にも嵌合状態の不具合は見られていない。しかしながら、先端部５Ａの全長αに対するリブ５Ｂの１つ当たりの長さβの比β／αが０．０３未満の試験体Ａと、比β／αが０．２５を超える試験体Ｇでは、脱着を３回行った後、連結箇所１０から水泡が発生している。一方、試験体Ｂ～Ｆでは、脱着を３回行った後でも水泡は発生していない。さらに比β／αが０．０５以上、０．２０以下である試験体Ｃ～Ｅでは、脱着を５回行った後でも水泡は発生していない。このように比β／αを適切に設定することで、排気ホース５を繰り返し脱着した後でも、嵌合状態を良好に維持できることがわかる。 Before the exhaust hose 5 is attached / detached, none of the test specimens has been found to be in a fitted state. However, in the specimen A in which the ratio β / α of the length β per rib 5B to the total length α of the tip 5A is less than 0.03 and the specimen G in which the ratio β / α exceeds 0.25, After performing desorption 3 times, water bubbles are generated from the connecting portion 10. On the other hand, in the test bodies B to F, water bubbles were not generated even after the desorption was performed three times. Further, in the test bodies C to E having the ratio β / α of 0.05 or more and 0.20 or less, no water bubbles are generated even after the desorption is performed 5 times. Thus, it can be seen that by properly setting the ratio β / α, the fitting state can be maintained satisfactorily even after the exhaust hose 5 is repeatedly detached.

　なお上述の例では、排気ホース５にリブ５Ｂが２つある場合を示したが、排気ホース５にリブ５Ｂが１つの場合でも、基本的に比β／αの適正範囲や効果は変わらない。また上述の例では、先端部５Ａが図５Ａで示される形状の場合を示したが、他の形状であっても比β／αの適正範囲や効果は変わらない。 In the above example, the exhaust hose 5 has two ribs 5B. However, even if the exhaust hose 5 has one rib 5B, the appropriate range and effect of the ratio β / α basically remain unchanged. In the above example, the tip 5A has the shape shown in FIG. 5A. However, the appropriate range and effect of the ratio β / α are not changed even if the tip 5A has another shape.

　以上、本発明を好適な実施形態により説明してきたが、こうした記述は限定事項ではなく、もちろん、種々の改変が可能である。例えば、蓋４に、排出口３Ａが設けられた第一端の反対側の第二端にも円筒状に窪んだ排出口を設け、この排出口を栓で封口してもよい。このような栓について、実施の形態２で詳細に説明する。 As mentioned above, although this invention has been demonstrated by suitable embodiment, such description is not a limitation matter and of course various modifications are possible. For example, the lid 4 may be provided with a cylindrically recessed outlet at the second end opposite to the first end where the outlet 3A is provided, and the outlet may be sealed with a stopper. Such a stopper will be described in detail in Embodiment 2.

　（実施の形態２）
　本発明の実施の形態２の説明に先立ち、従来の構成における問題点を簡単に説明する。排出口が排気経路の両側に設けられている鉛蓄電池において、特許文献１のようにネジ構造の栓を用いて、封口すべき側の排出口を封口する場合、栓の直径は１ｃｍ程度であるため、このような小さな部品を排出口にドライバー等で装着する際の作業性は著しく低い。また、使用者が試行錯誤して栓の取り付けと取り外しを繰り返すと、栓や排出口に設けられたネジ山が破損して、封口後の密閉性が保てなく虞がある。 (Embodiment 2)
Prior to the description of the second embodiment of the present invention, problems in the conventional configuration will be briefly described. In a lead-acid battery in which discharge ports are provided on both sides of the exhaust path, when the discharge port on the side to be sealed is sealed using a screw-structured plug as in Patent Document 1, the diameter of the plug is about 1 cm. Therefore, workability when such small parts are attached to the discharge port with a screwdriver or the like is extremely low. Further, if the user repeatedly attaches and removes the plug by trial and error, the screw threads provided on the plug and the outlet may be damaged, and the sealing after sealing may not be maintained.

　本実施の形態では、自身の車の仕様を熟知していない使用者が試行錯誤して、排出口に栓を取り付けと取り外しを繰り返しても密閉性を保つことができ、しかも装着時の作業性に優れた鉛蓄電池について説明する。 In this embodiment, a user who is not familiar with the specifications of his / her car can maintain the sealing performance even after repeated installation and removal of the plug at the outlet through trial and error, and workability at the time of installation An excellent lead storage battery will be described.

　以下、本実施の形態による鉛蓄電池について図面を参照しながら説明する。なお、実施の形態１と同様の構成には同じ符号を付して説明を省略する場合がある。また、鉛蓄電池における、栓以外の基本的な構造は図１に示した鉛蓄電池２０と同様なので、基本的構造の詳細な説明は省略し、栓および排気経路、排出口を中心に説明する。 Hereinafter, the lead storage battery according to the present embodiment will be described with reference to the drawings. In addition, the same code | symbol may be attached | subjected to the structure similar to Embodiment 1, and description may be abbreviate | omitted. In addition, since the basic structure of the lead storage battery other than the plug is the same as that of the lead storage battery 20 shown in FIG. 1, detailed description of the basic structure is omitted, and the plug, the exhaust path, and the discharge port will be mainly described.

　図８Ａ～図８Ｃは本実施の形態による鉛蓄電池の部分断面図である。この鉛蓄電池の蓋４の内部に設けられた排気経路３の両端には円筒状に窪んだ排出口３Ａを有する。実施の形態１で説明したように、排気経路３は複数のセル室と連通している。樹脂製の栓１５は排出口３Ａの一方を封口している。 8A to 8C are partial cross-sectional views of the lead storage battery according to the present embodiment. At both ends of the exhaust path 3 provided inside the lid 4 of the lead storage battery, there are exhaust ports 3A that are recessed in a cylindrical shape. As described in the first embodiment, the exhaust path 3 communicates with a plurality of cell chambers. The resin plug 15 seals one of the discharge ports 3A.

　図８Ａに示すように、鉛蓄電池は、工場で電解液が注入されて出荷される場合、流通している間には、両方の排出口３Ａを栓１５が封じている。そして、鉛蓄電池を自動車に搭載する際には、栓１５の一方が外され、図８Ｂや図８Ｃに示すように、開放された排出口３Ａの一方に、実施の形態１で説明した排気ホース５が嵌合される。また、自身の車の仕様（排気ホース５の配置）を熟知していない使用者が、外すべきではない方の栓１５を外したとしても、その外した栓１５を排出口３Ａに付け直し、もう一方の栓１５を外して開放された排出口３Ａに排気ホース５を嵌合させることができる。 As shown in FIG. 8A, when the lead storage battery is shipped with the electrolyte injected at the factory, the plug 15 seals both the outlets 3A during distribution. When the lead storage battery is mounted on the automobile, one end of the plug 15 is removed, and as shown in FIGS. 8B and 8C, the exhaust hose described in the first embodiment is connected to one of the opened outlets 3A. 5 is fitted. Further, even if a user who is not familiar with the specifications of the car (disposition of the exhaust hose 5) removes the stopper 15 that should not be removed, the removed stopper 15 is reattached to the outlet 3A. The exhaust hose 5 can be fitted into the discharge port 3A opened by removing the other plug 15.

　樹脂製の栓１５は、内部が空洞である円筒状の筒部１５Ａと、筒部１５Ａの一端を塞ぐ平板１５Ｃとを有する。筒部１５Ａには、その一部を周回するように連続したリブ１５Ｂが設けられている。排出口３Ａの内径Ｋ、筒部１５Ａにおけるリブ１５Ｂ以外の部分の外径Ｌ、リブ１５Ｂの外径Ｍ、平板１５Ｃの最少寸法Ｎは、Ｌ＜Ｋ＜Ｍ＜Ｎの関係を満たしている。また、リブ１５Ｂと平板１５Ｃとが離間している。なお、平板１５Ｃが円板状である場合、最少寸法Ｎは平板１５Ｃの直径である。 The resin plug 15 has a cylindrical tube portion 15A having a hollow inside, and a flat plate 15C that closes one end of the tube portion 15A. The cylindrical portion 15A is provided with a continuous rib 15B so as to go around a part thereof. The inner diameter K of the discharge port 3A, the outer diameter L of the cylindrical portion 15A other than the rib 15B, the outer diameter M of the rib 15B, and the minimum dimension N of the flat plate 15C satisfy the relationship L <K <M <N. Further, the rib 15B and the flat plate 15C are separated from each other. When the flat plate 15C has a disk shape, the minimum dimension N is the diameter of the flat plate 15C.

　排気経路３の両端に排出口３Ａが設けられている場合、使用しない側の排出口３Ａを封口する必要がある。工場で電解液が注入されずに鉛蓄電池が出荷される場合、流通している間には、両方の排出口３Ａが開放されている。そして、自身の車の仕様を熟知していない使用者にとっては、片方の排出口３Ａを封口する栓１５が別部品として同梱され、封口すべき側の排出口３Ａを見極めてから栓１５で封口する方が、誤って適合しない鉛蓄電池を購入してしまうことがないので好都合である。 When the exhaust port 3A is provided at both ends of the exhaust path 3, it is necessary to seal the unused exhaust port 3A. When the lead storage battery is shipped without the electrolyte being injected at the factory, both outlets 3A are open during distribution. For a user who is not familiar with the specifications of his / her car, a plug 15 for sealing one discharge port 3A is included as a separate part, and the plug 15 is used after checking the discharge port 3A on the side to be sealed. Sealing is more convenient because you will not accidentally purchase lead-acid batteries that do not fit.

　但しこのように自身の車の仕様を熟知していない使用者は、鉛蓄電池を車載する際に、封口すべき側の排出口３Ａを見誤って、栓１５の取り付けと取り外しを繰り返すと想定される。本実施の形態では栓１５で排出口３Ａを封じるので、使用者が簡便に、かつ誤認することなく、封口後の密閉性が保つことができる。 However, it is assumed that a user who is not familiar with the specifications of his / her car repeats the installation and removal of the plug 15 by mistakenly looking at the discharge port 3A on the side to be sealed when the lead-acid battery is mounted on the vehicle. The In the present embodiment, since the discharge port 3A is sealed with the stopper 15, the sealing performance after the sealing can be maintained easily and without misunderstanding by the user.

　前述のように、排出口３Ａの内径Ｋよりも筒部１５Ａの外径Ｌが小さい。そのため、排出口３Ａに無理なく筒部１５Ａを挿入できる。但し、リブ１５Ｂの外径Ｍは排出口３Ａの内径Ｋよりも大きいので、リブ１５Ｂは、隙間を生じさせることなく排出口３Ａの内壁面に嵌合される。 As described above, the outer diameter L of the cylindrical portion 15A is smaller than the inner diameter K of the discharge port 3A. Therefore, the cylinder portion 15A can be inserted into the discharge port 3A without difficulty. However, since the outer diameter M of the rib 15B is larger than the inner diameter K of the discharge port 3A, the rib 15B is fitted to the inner wall surface of the discharge port 3A without causing a gap.

　筒部１５Ａの全長γに対するリブ１５Ｂの１つ当たりの長さδの比δ／γは、０．０３以上、０．２５以下であることが好ましい。この理由は、実施の形態１における比β／αと同様である。 The ratio δ / γ of the length δ per rib 15B to the total length γ of the cylindrical portion 15A is preferably 0.03 or more and 0.25 or less. The reason is the same as the ratio β / α in the first embodiment.

　なお蓋４、栓１５ともに樹脂製であるため、排出口３Ａ、筒部１５Ａともに断面を真円とすることは困難であり、断面は僅かに歪んだ楕円となることが多い。その場合、しかしながら、筒部１５Ａの内部は空洞であるので、筒部１５Ａは、それ自身あるいは排出口３Ａの歪みを吸収するように容易に変形できる。この変形により、排出口３Ａと栓１５とは水密に結合し、密閉性を保つことができる。なお筒部１５Ａの肉厚が筒部１５Ａの外径に対して５％以上、２５％以下、より好ましくは８％以上、１５％以下であると、歪みを吸収するために筒部１５Ａが容易に変形できるので好ましい。 Since both the lid 4 and the plug 15 are made of resin, it is difficult to make the cross section of the discharge port 3A and the cylinder portion 15A into a perfect circle, and the cross section often becomes a slightly distorted ellipse. In this case, however, since the inside of the cylinder portion 15A is hollow, the cylinder portion 15A can be easily deformed so as to absorb the distortion of itself or the discharge port 3A. By this deformation, the discharge port 3A and the plug 15 are water-tightly coupled, and the hermeticity can be maintained. When the thickness of the cylinder portion 15A is 5% or more and 25% or less, more preferably 8% or more and 15% or less with respect to the outer diameter of the cylinder portion 15A, the cylinder portion 15A can be easily absorbed to absorb distortion. It is preferable because it can be transformed into

　排出口３Ａの内径Ｋよりも大きい外径Ｍを有するリブ１５Ｂを排出口３Ａに無理なく取り付けるために、リブ１５Ｂの形状は、少なくとも挿入方向に向かって外径Ｍが徐々に小さくなるようにすることが好ましい。この条件を満たすリブ１５Ｂの形態は、図１１Ａ～図１１Ｅに示すように、種々挙げることができる。図１１Ａ～図１１Ｅは栓１５と、リブ１５Ｂとの断面のバリエーションを示している。なお、リブ１５Ｂとは筒部１５Ａにおいて他の部分よりも外径が大きくなっている全ての箇所を指す。そして、リブ１５Ｂの１つ当たりの長さとはδで示される長さを指す。リブ１５Ｂの外径Ｍとはその中で最も外径が大きい箇所の寸法を指す。 In order to reasonably attach the rib 15B having the outer diameter M larger than the inner diameter K of the discharge port 3A to the discharge port 3A, the shape of the rib 15B is such that the outer diameter M gradually decreases at least in the insertion direction. It is preferable. Various forms of the rib 15B satisfying this condition can be cited as shown in FIGS. 11A to 11E. 11A to 11E show variations of the cross section of the plug 15 and the rib 15B. In addition, the rib 15B refers to all locations where the outer diameter is larger than other portions in the cylindrical portion 15A. The length per rib 15B indicates the length indicated by δ. The outer diameter M of the rib 15B refers to the dimension of the portion having the largest outer diameter.

　さらに、筒部１５Ａの一端を塞ぐ平板１５Ｃの最少寸法Ｎは、リブ１５Ｂの外径Ｍよりも大きい。そのため、使用者は栓１５を指先で容易に押し込むことができる。栓１５は、誤って装着したときに取り外せることを前提としている。そのため、栓１５を取り外す際のトリガーとなる個所が設けられていることが好ましい。平板１５Ｃの最少寸法Ｎがリブ１５Ｂの外径Ｍよりも大きいため、平板１５Ｃと隆起部４Ａとの間に精密ドライバーなど先端が鋭利な治具を差し込むことで、使用者は栓１５を容易に外すことができる。 Furthermore, the minimum dimension N of the flat plate 15C that closes one end of the cylindrical portion 15A is larger than the outer diameter M of the rib 15B. Therefore, the user can easily push the plug 15 with the fingertip. It is assumed that the stopper 15 can be removed when it is accidentally attached. Therefore, it is preferable that a portion serving as a trigger when removing the plug 15 is provided. Since the minimum dimension N of the flat plate 15C is larger than the outer diameter M of the rib 15B, a user can easily attach the plug 15 by inserting a jig with a sharp tip such as a precision screwdriver between the flat plate 15C and the raised portion 4A. Can be removed.

　もしリブ１５Ｂと平板１５Ｃとが密接していると、先端が鋭利な治具を差し込んで栓１５を取り外す際に治具の先端がリブ１５Ｂを傷つけてしまう虞がある。このようにリブ１５Ｂが傷つくと、その後の取り付けにおいて密閉性が損なわれる。したがってリブ１５Ｂと平板１５Ｃとは離間している。またリブ１５Ｂと平板１５Ｃとが離間していることで、使用者は、リブ１５Ｂが排出口３Ａの内壁を摩擦しながら通過する感覚の後に、平板１５Ｃが隆起部４Ａに衝突する感覚を得る。そのため、使用者は、筒部１５Ａが排気経路３に確実に挿入されたことを体感できる。したがって、使用者が中途半端な挿入状態で作業を終えることがなくなる。上述した効果を確実に得るためには、リブ１５Ｂは平板１５Ｃから０．５ｍｍ以上離間していることが好ましい。なお栓１５の取り外しを容易にする（平板１５Ｃと隆起部４Ａとの間に治具を差し込みやすくする）ためには、平板１５Ｃの最外部の肉厚を、図１０に示すように他の部位よりも小さくすることが望ましい。 If the rib 15B and the flat plate 15C are in close contact with each other, there is a possibility that the tip of the jig may damage the rib 15B when the jig 15 having a sharp tip is inserted and the plug 15 is removed. If the rib 15B is damaged in this way, the sealing performance is impaired in the subsequent attachment. Therefore, the rib 15B and the flat plate 15C are separated from each other. Further, since the rib 15B and the flat plate 15C are separated from each other, the user gets a feeling that the flat plate 15C collides with the raised portion 4A after feeling that the rib 15B passes while rubbing the inner wall of the discharge port 3A. Therefore, the user can experience that the cylinder portion 15 </ b> A is reliably inserted into the exhaust path 3. Therefore, the user does not finish the work in the halfway insertion state. In order to surely obtain the above-described effect, it is preferable that the rib 15B is separated from the flat plate 15C by 0.5 mm or more. In order to facilitate the removal of the plug 15 (to facilitate the insertion of a jig between the flat plate 15C and the raised portion 4A), the outermost wall thickness of the flat plate 15C is set to other parts as shown in FIG. It is desirable to make it smaller.

　栓１５に、筒部１５Ａの延伸方向に互いに離間したリブ１５Ｂが２つあれば、リブ１５Ｂのうち１つが破損しても、もう１つのリブ１５Ｂによって密閉性が保たれるので好ましい。また上述したように、栓１５は樹脂成型品であるため、対称形に成形されない場合がある。図１２Ａ、図１２Ｂではその一例として、リブ１５Ｂが非対称である栓１５を用いた場合を示している。このような場合でも、図１２Ａに示すようにリブ１５Ｂが２つ設けられた栓１５は、排出口３Ａに偏心した形で挿入されても、２つのリブ１５Ｂともに排出口３Ａに密着できるので密閉性が保たれる。しかしながら、図１２Ｂに示すようにリブ１５Ｂが３つ設けられた栓１５では、排出口３Ａに偏心した形で挿入されると、点線矢印で示した経路の隙間が生じてしまう虞がある。よって２つのリブ１５Ｂが設けられた栓１５が、種々のケースにおいて良好な密閉性を保てる最善の形状を有する。したがって、リブ１５Ｂは１つまたは２つ設けられていることが好ましい。 If the plug 15 has two ribs 15B spaced apart from each other in the extending direction of the cylindrical portion 15A, even if one of the ribs 15B is broken, the sealing performance is maintained by the other rib 15B. As described above, since the plug 15 is a resin molded product, it may not be formed symmetrically. In FIG. 12A and FIG. 12B, the case where the stopper 15 whose rib 15B is asymmetric is used is shown as an example. Even in such a case, the plug 15 provided with two ribs 15B as shown in FIG. 12A can be tightly sealed because both the ribs 15B can be in close contact with the discharge port 3A even if they are inserted in an eccentric manner in the discharge port 3A. Sex is maintained. However, as shown in FIG. 12B, when the plug 15 having three ribs 15B is inserted in an eccentric manner into the discharge port 3A, a gap in the path indicated by the dotted arrow may occur. Therefore, the plug 15 provided with the two ribs 15B has the best shape that can maintain good sealing performance in various cases. Therefore, it is preferable that one or two ribs 15B are provided.

　また図１３に示すように、蓋４の排気経路３に平行な最大長さＸ、排気経路３の長さＹ、平板１５Ｃの厚さＺは、Ｘ≧Ｙ＋２Ｚの関係を満たすことが好ましい。図１３は本実施の形態による鉛蓄電池の部分平面図である。このように、排気経路３に平行な方向において、平板１５Ｃが蓋４よりも突出しないようにすることで、輸送時や車載時に平板１５Ｃに衝撃が加わることが防止できる。したがって、排出口３Ａに対する栓１５の挿入が不十分になり、密閉性が低下するという不具合を回避できる。 Further, as shown in FIG. 13, it is preferable that the maximum length X of the lid 4 parallel to the exhaust path 3, the length Y of the exhaust path 3, and the thickness Z of the flat plate 15 C satisfy the relationship X ≧ Y + 2Z. FIG. 13 is a partial plan view of the lead storage battery according to the present embodiment. Thus, by preventing the flat plate 15C from protruding beyond the lid 4 in a direction parallel to the exhaust path 3, it is possible to prevent an impact from being applied to the flat plate 15C during transportation or in the vehicle. Therefore, it is possible to avoid the problem that the insertion of the plug 15 into the discharge port 3A becomes insufficient and the sealing performance is lowered.

　以上の説明から理解できるように、実施の形態１における排気ホース５と実施の形態２における栓１５とは、排出口３Ａに容易に脱着できるとともに装着された際の密封性を確保するために、共通の特徴を有している。 As can be understood from the above description, the exhaust hose 5 in the first embodiment and the plug 15 in the second embodiment can be easily detached from the discharge port 3A and ensure sealing performance when mounted. Has common features.
