Description

【０００１】
【発明の属する技術分野】
本発明は、密閉型鉛蓄電池の出入力端子に関するものである。
【０００２】
【従来の技術】
従来の密閉型鉛蓄電池の斜視図を図４に示す。
【０００３】
図４に示したように、蓋に設けた出入力端子２０は鉛合金製の座部（ナット）とを一体にしたものであり、前記ボルトの頭部と座部の下部周辺は、蓋の上面に設けられた鉛合金製のブッシングの内部に埋め込まれている。
【０００４】
【発明が解決しようとする課題】
従来の構造では、前記出入力端子２０にＯ型のリング状ワッシャーを一端に備えたリード線を接続する際には前記ワッシャーをはめ込みこれをナットによって固定していた。
【０００５】
しかしながら、出入力端子のボルトは銅合金製でありこれにワッシャーをはめ込んでナットでしめつけると、ボルト部分の強度が低いためボルトが折れてしまうことがあった。
【０００６】
本発明は、これらの課題を解決するものであり、出入力端子部分の強度に優れた密閉型鉛蓄電池を提供するものである。
【０００７】
【課題を解決するための手段】
上記の課題を解決するために本発明の密閉型鉛蓄電池は、蓋に設けた出入力端子が、銅製のボルトとこのボルトの下部に配された銅合金製の座部とからなり、前記ボルトの頭部と座部の下部周辺を、蓋の上面に設けられた鉛合金製のブッシング内に埋設したものである。
【０００８】
【発明の実施の形態】
本発明の電池では出入力端子を構成するボルト部分を鋼製にしているため、従来の銅合金製よりもボルト部分の強度を高めることができる。
【０００９】
さらに、出入力端子をリード線と接続する場合には、リード線の一端に備えられたＯ型のリング状ワッシャーを、ボルトの下部にあり内部抵抗の小さい銅合金製の座部の上面に接触させるため、通電時の電気抵抗を小さくして電池から大きな電流を取出すことができる。
【００１０】
【実施例】
以下、本発明の実施例を図面を参照して説明する。
【００１１】
図１は本発明の密閉型電池の側面断面図である。
【００１２】
図１に示したように、極板上部に耳部１１を備えた正極板１２と負極板１３とを微細ガラス繊維を主成分とするセパレータ１４を介して交互に並べた極板群１５が、ポリプロピレン樹脂からなるモノブロック型電槽１の各セル室３内に収納されている。
【００１３】
極板群１５は、同極性極板の耳部相互がストラップ５により接続されており、ストラップ５の上面の一端には正極端子６または負極端子７が備えられている。
【００１４】
次に出入力端子部分の構造を図２、図３を用いて説明する。
【００１５】
図２、図３に示したように出入力端子２０は、鋼製のボルト２１とそのボルトの下部に配された銅合金製の座部２２とからなり、ボルト頭部と座部の下部周辺は鉛合金製のブッシング２３内に埋設されるとともに座部２２の周囲には接着剤２４が充填されている。
【００１６】
出入力端子２０を備えたブッシング２３は蓋９と一体に成型されており、ブッシング２３は極板群上部のストラップ５に備えられた極柱２５と接続されている。
【００１７】
そして、電池を機器に接続するに際してＯ型のリング状ワッシャーを一端に備えたリード線を出入力端子２０に接続するには、前記ワッシャーを前記銅合金製座部２２に接触固定させている。
【００１８】
ここでの出入力端子では、従来の銅製のボルトに変わって鋼製のボルトを用いているので端子の強度を向上させることができるとともに、リード線との接触時にはリード線の一端を内部抵抗の小さい銅合金製の座部と接触させるので通電時の電気抵抗を小さくすることができ、結果として電池から大きな電流を取り出すことができる。
【００１９】
【発明の効果】
以上のように本発明の密閉型電池では、出入力端子を鋼製のボルトと銅合金製の座部とにより構成しているので、ボルト部分の強度を高めることができるとともに、リード線の一端を銅合金製の座部に接続することにより通電時の電気抵抗を小さくすることができる。

BACKGROUND OF THE INVENTION
The present invention relates to an input / output terminal of a sealed lead-acid battery.
[0002]
[Prior art]
A perspective view of a conventional sealed lead-acid battery is shown in FIG.
[0003]
As shown in FIG. 4, the input / output terminal 20 provided on the lid is an integral part of a lead alloy seat (nut), and the bolt head and the lower periphery of the seat are located on the lid. It is embedded in a lead alloy bushing provided on the upper surface.
[0004]
[Problems to be solved by the invention]
In the conventional structure, when connecting a lead wire having an O-shaped ring washer at one end to the input / output terminal 20, the washer is fitted and fixed with a nut.
[0005]
However, the bolts of the input / output terminals are made of a copper alloy, and when a washer is fitted into this and fastened with a nut, the bolt may break because the strength of the bolt portion is low.
[0006]
The present invention solves these problems and provides a sealed lead-acid battery excellent in strength of an input / output terminal portion.
[0007]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the sealed lead-acid battery of the present invention has an input / output terminal provided on a lid comprising a copper bolt and a copper alloy seat disposed below the bolt, the bolt The head and the lower periphery of the seat are embedded in a lead alloy bushing provided on the upper surface of the lid.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
In the battery of the present invention, since the bolt portion constituting the input / output terminal is made of steel, the strength of the bolt portion can be increased as compared with the conventional copper alloy.
[0009]
Further, when connecting the input / output terminal to the lead wire, an O-shaped ring washer provided at one end of the lead wire is brought into contact with the upper surface of the seat made of copper alloy having a low internal resistance at the lower part of the bolt. Therefore, it is possible to take out a large current from the battery by reducing the electrical resistance during energization.
[0010]
【Example】
Embodiments of the present invention will be described below with reference to the drawings.
[0011]
FIG. 1 is a side sectional view of a sealed battery of the present invention.
[0012]
As shown in FIG. 1, an electrode plate group 15 in which the positive electrode plate 12 and the negative electrode plate 13 provided with the ears 11 at the upper part of the electrode plate are alternately arranged via the separators 14 mainly composed of fine glass fibers, It is accommodated in each cell chamber 3 of a monoblock type battery case 1 made of polypropylene resin.
[0013]
In the electrode plate group 15, the ears of the same polarity electrode plates are connected to each other by the strap 5, and the positive electrode terminal 6 or the negative electrode terminal 7 is provided at one end of the upper surface of the strap 5.
[0014]
Next, the structure of the input / output terminal portion will be described with reference to FIGS.
[0015]
As shown in FIGS. 2 and 3, the input / output terminal 20 includes a steel bolt 21 and a copper alloy seat 22 disposed below the bolt, and the bolt head and the lower periphery of the seat. Is embedded in a bushing 23 made of a lead alloy and an adhesive 24 is filled around the seat portion 22.
[0016]
A bushing 23 having an input / output terminal 20 is formed integrally with the lid 9, and the bushing 23 is connected to a pole column 25 provided on the strap 5 at the top of the electrode plate group.
[0017]
In order to connect a lead wire having an O-shaped ring washer at one end to the input / output terminal 20 when the battery is connected to the device, the washer is contacted and fixed to the copper alloy seat portion 22.
[0018]
The I / O terminals here use steel bolts instead of the conventional copper bolts, so that the strength of the terminals can be improved and one end of the lead wire is connected to the internal resistance when in contact with the lead wire. The contact with the small copper alloy seat can reduce the electrical resistance when energized, and as a result, a large current can be taken out from the battery.
[0019]
【The invention's effect】
As described above, in the sealed battery according to the present invention, the input / output terminal is constituted by the steel bolt and the copper alloy seat, so that the strength of the bolt portion can be increased and one end of the lead wire can be obtained. By connecting to a copper alloy seat, the electrical resistance during energization can be reduced.
