Description
本発明は鉛蓄電池に関し、更に詳しくは、正負極識別表示手段を備えた鉛蓄電池に関する。 The present invention relates to a lead storage battery, and more particularly to a lead storage battery provided with positive and negative electrode identification display means.
従来、鉛蓄電池の正極側端子と負極側端子とを識別するために、蓋の上面に極性を示す「＋」と「−」の文字が刻印されていた。しかし、端子に接続体を接続するに際しては、どうしても端子自体に作業者の目が行くこと、また、該刻印は蓋と同色であることから見逃し易く、従って、該刻印のみでは、正負極の識別を誤り易いと言う問題を有していた。 Conventionally, in order to distinguish between a positive electrode side terminal and a negative electrode side terminal of a lead storage battery, characters “+” and “−” indicating polarity are engraved on the upper surface of the lid. However, when connecting the connector to the terminal, it is easy to miss the operator's eyes on the terminal itself and the marking is the same color as the lid. Had the problem of being easy to make mistakes.
該問題を解決するために、例えば、電槽蓋の上面に突出する円筒状の極性端子座の外周面に、スリットを設けて開環されかつ内周にスペース形成面を形成した極性表示用リングを嵌着せしめた、電池の極柱端子の極性表示装置が知られている（特許文献１）。また、導電端子付近に判別部品が固定される電池の正負極判別電池蓋構造において、正、負極の識別部品は、異なる色の絶縁プラスチック材を射出方式で電池蓋に固定することにより設けられる、電池の正負極判別電池蓋構造が知られている（特許文献２）。前者は、極性表示用リングを、好ましくは赤色と白色とに着色して正負極を識別するものであり、後者も、同様に、異なる色、好ましくは赤色と黒色の絶縁プラスチック材により正負極を識別するものである。このように色彩により正負極を判別するものとしては、その他、端子封口部の接着剤の色彩を変えたり、また、色彩の異なる極示シールを貼付したりすることが知られている。しかし、これらの方法では、色違いの着色剤、極示シールや極性表示用リング等の部品点数が増えることになり、鉛蓄電池の製造コストが嵩むことになる。また、切削加工により端子表面を削り出すことにより端子部が形成される鉛蓄電池にあっては、接着剤による正負極の色分けが困難であり、かつ、削り出した平滑な端子表面に接続部品の邪魔をすることなく、極示シールを貼付することも容易ではない。 In order to solve the problem, for example, a polarity display ring in which a slit is provided on the outer peripheral surface of a cylindrical polar terminal seat protruding from the upper surface of the battery case lid and a space forming surface is formed on the inner periphery. There has been known a polarity display device for a battery pole terminal in which is attached (Patent Document 1). Further, in the battery positive / negative discrimination battery lid structure in which the discrimination component is fixed near the conductive terminal, the positive and negative discrimination components are provided by fixing different colors of insulating plastic materials to the battery lid by an injection method. A battery lid structure for distinguishing positive and negative electrodes of a battery is known (Patent Document 2). In the former, the polarity display ring is preferably colored in red and white to identify the positive and negative electrodes, and in the latter, the positive and negative electrodes are similarly made of insulating plastic materials of different colors, preferably red and black. To identify. In addition, it is known that the positive and negative electrodes are discriminated based on the color in this manner, such as changing the color of the adhesive at the terminal sealing portion, or attaching a sticker with a different color. However, these methods increase the number of parts such as different colorants, pole seals, and polarity display rings, and increase the manufacturing cost of lead-acid batteries. In addition, in a lead storage battery in which the terminal portion is formed by cutting the terminal surface by cutting, it is difficult to color-code the positive and negative electrodes with an adhesive, and the connecting parts are attached to the smooth terminal surface that has been cut. It is not easy to put the pole sticker without disturbing.
本発明は、部品点数が少ないと共に製造が容易であることから製造コストを低減し得、かつ、正極と負極とを外部から目視により容易かつ確実に識別可能な正負極識別表示手段を備えた鉛蓄電池を提供するものである。 The present invention can reduce the manufacturing cost because it has a small number of parts and is easy to manufacture, and also includes a positive and negative electrode identification display means that can easily and reliably identify the positive electrode and the negative electrode from the outside. A storage battery is provided.
従来の鉛蓄電池において、色違いの着色剤、極示シール及び極性表示用リング等の別の新たな部品を使用することにより、部品点数が増えて製造コストが増加しているのなら、これらの部品を使用しないことが考えられる。しかし、そもそも、これらの部品は、従来の蓋の上面に刻印された「＋」と「−」の極性表示のみでは、極性の識別が不十分であったことに起因して設けられたものである。従って、これらの部品を単に使用しないのみでは、本来の目的、即ち、正負極端子を容易かつ確実に識別するという目的を達成できず、全く意味のないものとなってしまう。そこで、本発明者は、如何にすれば、これらの部品を使用せず、かつ、正負極端子の識別を容易かつ確実にし得るかについて、種々の検討を試みた。その結果、端子部表面の接着剤部分にくぼみ部を形成し、そして、そのくぼみ部の数を正極と負極とで異なるようにすれば、上記課題を解決し得ることを見出し、本発明を完成するに至った。 In conventional lead-acid batteries, if the number of parts increases and the manufacturing cost increases by using other new parts such as colorants of different colors, pole seals, and polarity display rings, these It is conceivable that no parts are used. However, in the first place, these parts are provided because the polarity is not sufficiently identified only by the polarity indication of “+” and “−” stamped on the upper surface of the conventional lid. is there. Therefore, if these components are not simply used, the original purpose, that is, the purpose of easily and surely identifying the positive and negative terminals cannot be achieved, and it becomes completely meaningless. Therefore, the present inventor has made various studies on how to use these components and to easily and reliably identify the positive and negative terminals. As a result, it was found that the above-mentioned problems can be solved by forming recesses in the adhesive part on the surface of the terminal part, and making the number of recesses different between the positive electrode and the negative electrode, and the present invention was completed. It came to do.
即ち、本発明は、

本発明の鉛蓄電池は、該蓄電池に備えられた正負極識別表示手段の製造コストが安価であるばかりではなく、該識別表示手段として、端子部表面の接着剤部分に現れるくぼみ部の数を、正極側と負極側とで異ならしめたことにより、好ましくは、正極側の接着剤部分に現れるくぼみ部を９０度間隔で４個として、該くぼみ部から「＋」のイメージを直観させることにより、端子接続作業時に正極と負極とを、外部から目視により容易かつ確実に識別可能である。 The lead storage battery of the present invention is not only low in the manufacturing cost of the positive and negative electrode identification display means provided in the storage battery, but also as the identification display means, the number of indentations appearing in the adhesive portion of the terminal portion surface, By making the difference between the positive electrode side and the negative electrode side, preferably, four depressions appearing in the adhesive part on the positive electrode side at 90 degree intervals, and by making the image of “+” intuitively from the depressions, The positive electrode and the negative electrode can be easily and reliably identified from the outside during terminal connection work.
本発明の鉛蓄電池は、端子極柱が蓋裏面の凹部内に挿入され、該凹部内に充填された接着剤により端子極柱全体を固定し、電池外側から切削加工により端子表面を削り出すことで端子部が形成される鉛蓄電池に関する。ここで、形成された端子部表面は、端子極柱、それを取り囲む接着剤、更にそれを取り囲む蓋を順次備える。本発明の鉛蓄電池においては、上記蓋裏面の凹部の内面が、形成された端子部表面の接着剤部分にくぼみ部を形成しないか又は１個以上のくぼみ部を形成せしめる形状を備える。そして、該凹部の内面形状の相違により、接着剤部分に形成されるくぼみ部の数が、正極側と負極側とで異なるようにしたものである。正極側凹部と負極側凹部の内面形状の相違は、切削加工により端子表面を削り出したときに端子部表面に露出する位置おいて異なることが必要である。上記の露出した端子極柱、それを取り囲む接着剤部分、及び、端子部の外縁を形成する蓋の外形は、いずれも略円形であることが好ましい。言い換えれば、端子極柱、及び、端子極柱が挿入される蓋裏面の凹部は、夫々、その長さ方向、及び、その深さ方向に垂直な面で切った断面形状がいずれも略円形であることが好ましい。 In the lead storage battery of the present invention, the terminal pole column is inserted into the recess on the back surface of the lid, the entire terminal pole column is fixed with the adhesive filled in the recess, and the terminal surface is cut out from the outside of the battery by cutting. It is related with the lead acid battery in which a terminal part is formed. Here, the surface of the formed terminal portion includes a terminal pole column, an adhesive surrounding it, and a lid surrounding it. In the lead storage battery of the present invention, the inner surface of the concave portion on the back surface of the lid has a shape that does not form a recessed portion or forms one or more recessed portions in the adhesive portion of the formed terminal portion surface. And the number of the recessed parts formed in an adhesive agent part is made to differ in the positive electrode side and the negative electrode side by the difference in the inner surface shape of this recessed part. The difference in the shape of the inner surface between the positive electrode side concave portion and the negative electrode side concave portion needs to be different in the position exposed on the terminal portion surface when the terminal surface is cut out by cutting. It is preferable that the exposed terminal pole columns, the adhesive portion surrounding the terminal pole columns, and the outer shape of the lid forming the outer edge of the terminal portion are all substantially circular. In other words, each of the terminal pole and the recess on the back surface of the lid into which the terminal pole is inserted has a substantially circular cross-section cut along a plane perpendicular to the length direction and the depth direction. Preferably there is.
本発明において、上記の蓋裏面の凹部の内面形状は、形成された端子部表面の接着剤部分に形成されるくぼみ部の数が、正極側と負極側とで異なるものになれば特に制限はない。例えば、正極側凹部の内面が、形成された端子部表面の接着剤部分に１個以上のくぼみ部を形成せしめる形状、好ましくは、正極側凹部の内面が、形成された端子部表面の接着剤部分に略等角度間隔で２〜８個のくぼみ部を形成せしめる形状、より好ましくは、略９０度間隔で４個のくぼみ部を形成せしめる形状を備える構造が挙げられる。上記のように、接着剤部分にくぼみ部を形成せしめるためには、正極側凹部の内面は、例えば、該凹部の深さ方向に沿って伸びる１個以上の突起部（リブ）、好ましくは、該凹部の深さ方向に沿って伸びる、略平行かつ略等角度間隔に設けられた２〜８個の突起部（リブ）、より好ましくは、略平行かつ略９０度間隔に設けられた４個の突起部（リブ）を備える構造を有する。ここで、これら突起部（リブ）は、電池外側から切削加工により端子表面を削り出したときに、端子部表面に露出する位置に備えることが必要である。上記のより好ましい構造とすることにより、端子接続作業時に作業者が、これら４個のくぼみ部又は突起部により、「＋」の文字をイメージして正極であることを、容易かつ確実に認識することが可能となる。また、上記いずれのより好ましい構造においても、上記４個のくぼみ部又は突起部のうち、相対する２個のくぼみ部又は突起部の中心を通る平面が、いずれも鉛蓄電池の蓋の端部を形成するいずれかの辺、即ち、縦又は横のいずれかの辺と垂直に交わることが好ましい。これにより、端子接続作業時に作業者が、正極であることをより一層容易かつ確実に認識することが可能となる。 In the present invention, the inner shape of the concave portion on the back surface of the lid is not particularly limited as long as the number of recessed portions formed in the adhesive portion of the formed terminal portion surface is different between the positive electrode side and the negative electrode side. Absent. For example, the inner surface of the concave portion on the positive electrode side has a shape in which one or more recessed portions are formed in the adhesive portion on the surface of the formed terminal portion, preferably the adhesive on the surface of the terminal portion on which the inner surface of the positive electrode side concave portion is formed. A structure having a shape in which 2 to 8 indentations are formed at approximately equal angular intervals in the portion, and more preferably a shape in which 4 indentations are formed at approximately 90 ° intervals. As described above, in order to form a concave portion in the adhesive portion, the inner surface of the positive electrode side concave portion is, for example, one or more protrusions (ribs) extending along the depth direction of the concave portion, preferably 2-8 protrusions (ribs) extending along the depth direction of the recesses and provided at substantially parallel and substantially equiangular intervals, more preferably 4 provided at approximately 90 ° intervals and substantially parallel. It has a structure provided with the projection part (rib). Here, these protrusions (ribs) need to be provided at positions that are exposed on the surface of the terminal portion when the terminal surface is cut out from the outside of the battery by cutting. By adopting the more preferable structure described above, an operator can easily and surely recognize that it is a positive electrode by imagining the character “+” by using these four recesses or protrusions during the terminal connection work. It becomes possible. Further, in any of the above-described more preferable structures, the plane passing through the centers of the two indentations or projections facing each other out of the four indentations or projections is the end of the lid of the lead storage battery. It is preferable to intersect perpendicularly with any side to be formed, that is, either the vertical or horizontal side. As a result, the operator can more easily and reliably recognize that it is the positive electrode during the terminal connection work.
一方、負極側凹部の内面は、接着剤部分に形成されるくぼみ部の数が正極側と異なるものであれば特に制限はないが、形成された端子部表面の接着剤部分に何らのくぼみ部をも形成しない構造、即ち、負極側凹部の内面の、電池外側から切削加工により端子表面を削り出したときに端子部表面に露出する位置に突起部（リブ）を備えていない構造であることが好ましい。また、２個のくぼみ部又は突起部を一直線状に配置すること、更に、該直線を鉛蓄電池の蓋の端部を形成する各辺のいずれかと垂直に交わるようにすることもできる。もちろん、上記の正極側端子部表面と負極側端子部表面の外観形状において、上記とは反対に、負極側端子部表面の接着剤部分にくぼみ部を設け、正極側にはくぼみ部を設けないようにすることもできる。しかし、負極側にくぼみ部を設ける態様では、作業者が負極を正極と誤る可能性があるため、上記したように正極側にくぼみ部を設ける態様がより好ましい。 On the other hand, the inner surface of the negative electrode side concave portion is not particularly limited as long as the number of the concave portions formed in the adhesive portion is different from that of the positive electrode side, but any concave portion is present in the adhesive portion of the formed terminal portion surface. In other words, the inner surface of the concave portion on the negative electrode side is not provided with a protrusion (rib) at a position exposed on the surface of the terminal portion when the terminal surface is cut from the outside of the battery by cutting. Is preferred. Further, the two indentations or protrusions may be arranged in a straight line, and the straight line may intersect perpendicularly with any one of the sides forming the end of the lead-acid battery lid. Of course, in the appearance shape of the positive electrode side terminal part surface and the negative electrode side terminal part surface, the concave part is provided in the adhesive part on the negative electrode side terminal part surface, and the concave part is not provided on the positive electrode side. It can also be done. However, in the aspect in which the indented part is provided on the negative electrode side, the operator may mistake the negative electrode as the positive electrode. Therefore, the aspect in which the indented part is provided on the positive electrode side as described above is more preferable.
上記の正極側凹部及び負極側凹部のいずれにおいても、電池外側から切削加工により端子表面を削り出したときに端子部表面に露出するものでなければ、上記以外の突起部（リブ）を内面に備えることができる。正極側凹部内面においては、例えば、合計８個の突起部（リブ）を有し、そのうち、４個の突起部（リブ）により、上記のより好ましい構造を与えることができるし、あるいは、合計４個の突起部（リブ）により上記のより好ましい構造を与えることもできる。負極側内面においては、例えば、合計４個の突起部（リブ）を有し、これらはいずれも、端子表面を削り出したときに端子部表面に露出しないようにすることができる。通常、正極側及び負極側内面とも合計４個の突起部（リブ）を備え、正極側内面に備えられた突起部（リブ）は、端子部表面に露出する部分まで伸びており、一方、負極側内面に備えられた突起部（リブ）は、正極側に備えられた突起部（リブ）より短く、端子部表面に露出する部分まで伸びていない構造が採用される。これらの突起部（リブ）はいずれも、正負極側凹部の端面（頂壁）から内面（側壁）に沿って伸びることが好ましい。また、これらの突起部（リブ）は、端子極柱を各凹部に挿入する際に、端子極柱を各凹部の略中央に位置付けるための補助的な役割も果たしている。 In any of the above-described positive-side concave portion and negative-electrode-side concave portion, a protrusion (rib) other than the above is provided on the inner surface unless the terminal surface is exposed to the surface of the terminal portion by cutting from the outside of the battery. Can be provided. The positive electrode-side concave inner surface has, for example, a total of eight protrusions (ribs), of which four protrusions (ribs) can give the more preferable structure described above, or a total of four The above-mentioned more preferable structure can be given by the individual protrusions (ribs). The inner surface of the negative electrode side has, for example, a total of four protrusions (ribs), and any of these can be prevented from being exposed to the terminal portion surface when the terminal surface is cut out. Usually, the positive electrode side and the negative electrode side inner surface are provided with a total of four protrusions (ribs), and the protrusions (ribs) provided on the positive electrode side inner surface extend to a portion exposed on the surface of the terminal portion, while the negative electrode The protrusion (rib) provided on the side inner surface is shorter than the protrusion (rib) provided on the positive electrode side, and a structure that does not extend to the portion exposed on the surface of the terminal portion is employed. Any of these protrusions (ribs) preferably extends along the inner surface (side wall) from the end surface (top wall) of the concave portion on the positive / negative electrode side. Further, these protrusions (ribs) also play an auxiliary role for positioning the terminal pole column at the approximate center of each recess when the terminal pole column is inserted into each recess.
本発明の鉛蓄電池は、通常公知の方法で組み立てて製造することができる。図１は、本発明の鉛蓄電池の一実施態様を示した平面図及び正面図であり、図２は、図１に示した本発明の鉛蓄電池の正極の拡大平面図であり、また、図３は、図１に示した本発明の鉛蓄電池の端子部全体の加工前後の断面図である。以下、上記の図１、図２及び図３に基づいて、本発明の鉛蓄電池の一実施態様について説明する。本発明の鉛蓄電池（Ａ）の電槽（１）は、合成樹脂製の、上面のみが開口した箱状であり、正極板と負極板とをセパレータを介して交互に積層して成る極板群が収納されている。該極板群には、正極及び負極の夫々の端子極柱（２，３）が設けられている。蓋（４）も同様に合成樹脂製であり下面のみが開口した浅い箱状であり、その開口する下面の周壁内面には全周に亘り凹溝（８）が形成されている。また、蓋（４）の上部内面には端子極柱（２，３）を受け入れる二つの凹部（７）が備えられている。まず、蓋（４）を逆さにして、凹部（７）と凹溝（８）に接着剤（５）を流し込み、次いで、極板群を収納した電槽（１）を倒立させて、蓋（４）の二つの凹部（７）に各端子極柱（２，３）を夫々挿入し、かつ、凹溝（８）に電槽（１）の開口する周壁先端（９）を挿入する。そして、接着剤が硬化することにより電槽（１）と蓋（４）とが接着され、かつ、各端子極柱（２，３）が接着剤（５）を介して蓋（４）の凹部（７）に夫々接着される。次いで、電槽を正立して、端子極柱（２，３）が挿入されている電槽（１）の凹部（７）を、外側からa-a部分を切削加工して端子表面を削り出すことにより、本発明の鉛蓄電池（Ａ）を製造することができる。ここで、a-a部分の、蓋（４）の表面（１２）から距離は、鉛蓄電池の寸法により異なるが、例えば、蓋（４）の表面（１２）から５ｍｍである。図１、図２及び図３に示した、本発明の鉛蓄電池（Ａ）は、正極の端子極柱（２）の端子部（６）表面の接着剤部分（５）に９０度間隔で４個のくぼみ部［１０（１０ａ，１０ｂ，１０ｃ，１０ｄ）］を有する。一方、負極の端子極柱（３）の端子部（６）表面の接着剤部分（５）には、このようなくぼみ部（１０）は備えられていない。図１及び２のように蓋（４）と接着剤（５）の色彩を明確に区別し得るものにしておけば、このようなくぼみ部（１０）の有無により、正極と負極とを外部から目視により容易かつ確実に識別することができる。該態様においては、相対する２個のくぼみ部、例えば、１０ａ及び１０ｂの中心を通る平面は、蓋（４）の端部を形成する辺、即ち、縦の辺に垂直に交わり、一方、１０ｃ及び１０ｄの中心を通る平面は、蓋（４）の端部を形成する辺、即ち、横の辺に垂直に交わる。ここで、正極端子部（６）の接着剤部分（５）に現れる４個のくぼみ部［１０（１０ａ，１０ｂ，１０ｃ，１０ｄ）］は、正極（２）が挿入される蓋（４）の凹部（７）に備えられている突起部（リブ）（１１）により形成されるものである。次いで、図３に基づいて、本発明の鉛蓄電池の端子部の切削加工の概略について説明する。図３の左側の上下の図は、夫々、負極側及び正極側端子部全体の加工前の断面図を示したものである。凹部（７）の内面に備えられている突起部（リブ）（１１）は、負極側で短く、正極側で長く作られている。次いで、ａ−ａ部分を切断して切削加工することにより端子表面が削り出される。この際、ａ−ａ部分より下方まで突起部（リブ）（１１）が伸びている正極側では、切削加工後においても突起部（リブ）（１１）が凹部（７）の内面に残ることにより、削り出された端子部（６）表面の接着剤部分（５）にくぼみ部（１０）を形成せしめる。一方、負極側では、突起部（リブ）（１１）がａ−ａ部分より下方まで伸びていないことから、切削加工後に突起部（リブ）（１１）が凹部（７）の内面に残らない。従って、負極側では、削り出された端子部（６）表面の接着剤部分（５）にくぼみ部（１０）が形成されない。 The lead acid battery of the present invention can be assembled and manufactured by a generally known method. FIG. 1 is a plan view and a front view showing an embodiment of the lead storage battery of the present invention, and FIG. 2 is an enlarged plan view of the positive electrode of the lead storage battery of the present invention shown in FIG. 3 is a cross-sectional view of the entire terminal portion of the lead storage battery of the present invention shown in FIG. 1 before and after processing. Hereinafter, based on said FIG.1, FIG.2 and FIG.3, one embodiment of the lead acid battery of this invention is demonstrated. The battery case (1) of the lead storage battery (A) of the present invention is a box made of a synthetic resin and having only an upper surface opened, and is formed by alternately laminating positive and negative plates through separators. A group is stored. The electrode plate group is provided with terminal pole columns (2, 3) of the positive electrode and the negative electrode, respectively. Similarly, the lid (4) is made of synthetic resin and has a shallow box shape in which only the lower surface is opened. A concave groove (8) is formed on the entire inner surface of the peripheral wall of the opened lower surface. In addition, the upper inner surface of the lid (4) is provided with two recesses (7) for receiving the terminal pole columns (2, 3). First, the lid (4) is turned upside down, the adhesive (5) is poured into the concave portion (7) and the concave groove (8), and then the battery case (1) containing the electrode plate group is inverted, and the lid ( The terminal poles (2, 3) are respectively inserted into the two recesses (7) of 4), and the peripheral wall tip (9) where the battery case (1) is opened is inserted into the recess (8). Then, the battery case (1) and the lid (4) are bonded by curing the adhesive, and the terminal poles (2, 3) are recessed in the lid (4) via the adhesive (5). Bonded to (7), respectively. Next, the battery case is erected, and the recess (7) of the battery case (1) in which the terminal pole columns (2, 3) are inserted is cut from the outside by cutting the aa portion from the outside. Thus, the lead storage battery (A) of the present invention can be manufactured. Here, the distance from the surface (12) of the lid (4) of the a-a portion is 5 mm from the surface (12) of the lid (4), although it varies depending on the size of the lead-acid battery. The lead-acid battery (A) of the present invention shown in FIGS. 1, 2 and 3 is 4 at 90 ° intervals on the adhesive part (5) on the surface of the terminal part (6) of the terminal pole column (2) of the positive electrode. It has a hollow part [10 (10a, 10b, 10c, 10d)]. On the other hand, the concave portion (10) is not provided in the adhesive portion (5) on the surface of the terminal portion (6) of the terminal pole column (3) of the negative electrode. If the colors of the lid (4) and the adhesive (5) can be clearly distinguished as shown in FIGS. 1 and 2, the positive electrode and the negative electrode are externally connected depending on the presence or absence of the depression (10). It can be easily and reliably identified visually. In this embodiment, the planes passing through the centers of two opposing indentations, for example 10a and 10b, intersect perpendicularly to the side forming the end of the lid (4), ie the vertical side, while 10c And the plane passing through the center of 10d perpendicularly intersects the side forming the end of the lid (4), that is, the lateral side. Here, the four recessed portions [10 (10a, 10b, 10c, 10d)] appearing in the adhesive portion (5) of the positive electrode terminal portion (6) are formed on the lid (4) into which the positive electrode (2) is inserted. It is formed by the protrusion (rib) (11) provided in the recess (7). Next, an outline of the cutting process of the terminal portion of the lead storage battery of the present invention will be described based on FIG. The upper and lower figures on the left side of FIG. 3 show cross-sectional views of the negative electrode side and the positive electrode side terminal part before processing. The protrusion (rib) (11) provided on the inner surface of the recess (7) is short on the negative electrode side and long on the positive electrode side. Next, the terminal surface is cut by cutting and cutting the aa portion. At this time, on the positive electrode side where the protrusions (ribs) (11) extend below the aa portion, the protrusions (ribs) (11) remain on the inner surface of the recesses (7) even after cutting. The indented portion (10) is formed in the adhesive portion (5) on the surface of the terminal portion (6) that has been cut out. On the other hand, on the negative electrode side, since the protrusion (rib) (11) does not extend below the aa portion, the protrusion (rib) (11) does not remain on the inner surface of the recess (7) after cutting. Therefore, on the negative electrode side, the recessed portion (10) is not formed in the adhesive portion (5) on the surface of the shaved terminal portion (6).
図５には、従来の鉛蓄電池の一実施態様の平面図及び正面図を示した。このような従来の鉛蓄電池（Ｂ）では、本発明の鉛蓄電池（Ａ）のように、正極の端子極柱（２）の端子部（６）表面の接着剤部分（５）にくぼみ部（１０）を備えていない。従って、蓋（４）の上面に刻印された「＋」と「−」の極性表示のみにより、正負極端子を識別しなければならない。 FIG. 5 shows a plan view and a front view of one embodiment of a conventional lead-acid battery. In such a conventional lead-acid battery (B), as in the lead-acid battery (A) of the present invention, a concave portion (5) is formed in the adhesive part (5) on the surface of the terminal part (6) of the terminal pole column (2) of the positive electrode. 10) is not provided. Therefore, the positive and negative terminals must be identified only by the polarity indications “+” and “−” stamped on the upper surface of the lid (4).
また、本発明の鉛蓄電池においては、端子極柱の側面、とりわけ、端子極柱の上部側面にローレット（１４）を施すことができる。これにより、端子の接続作業におけるネジ穴（１３）へのボルトの締め付けに対する回り止め効果を発揮することができる。図４は、本発明の鉛蓄電池の、ローレット（１４）を施した端子極柱（２，３）の一実施態様を示した平面図及び正面図である。該ローレット（１４）は、端子極柱（２，３）の長さ方向に沿って伸びる略平行な複数の溝を備えるものである。 Moreover, in the lead acid battery of this invention, a knurl (14) can be given to the side surface of a terminal pole column, especially the upper side surface of a terminal pole column. Thereby, the detent effect with respect to bolting to the screw hole (13) in the connection operation of a terminal can be exhibited. FIG. 4: is the top view and front view which showed one embodiment of the terminal pole column (2, 3) which gave the knurl (14) of the lead acid battery of this invention. The knurl (14) includes a plurality of substantially parallel grooves extending along the length direction of the terminal pole columns (2, 3).
本発明の鉛蓄電池は、該蓄電池に備えられた正負極識別表示手段の製造コストが安価であるばかりではなく、該識別表示手段により端子接続作業時に正極と負極とを、外部から目視により容易かつ確実に識別可能であることから、産業用鉛蓄電池として、今後、大いに利用されることが期待される。 The lead storage battery of the present invention is not only inexpensive in the production cost of the positive / negative electrode identification display means provided in the storage battery, but also the positive and negative electrodes can be easily and visually observed from the outside during the terminal connection operation by the identification display means. Since it can be reliably identified, it is expected to be used as an industrial lead-acid battery in the future.
