Description

【0001】
【発明の属する技術分野】
本発明は、鉛蓄電池用格子体に関するものである。
【0002】
【従来の技術】
従来の鉛蓄電池用格子体1は、図2に示すように、上枠骨2a、縦枠骨3a,3b、下枠骨2b、縦中骨4a、横中骨4bを有し、上枠骨2aの片側よりの位置に耳部5が設けられた構造であった(例えば、特許文献1参照。)。
【0003】
【特許文献1】
特許第2805910号公報(第1図)
【0004】
【発明が解決しようとする課題】
しかしながら、従来の鉛蓄電池用格子体1を使用した鉛蓄電池では、この格子体1が充放電中に上方向に伸び、対極のストラップに当たり短絡するという問題点があった。
【0005】
本発明の目的は、充放電中に上方向に伸び、対極のストラップに当たって短絡するのを防止できる鉛蓄電池用格子体を提供することにある。
【0006】
【課題を解決するための手段】
本発明は、上枠骨、縦枠骨、下枠骨、縦中骨、横中骨を有し、上枠骨に耳部が設けられている鉛蓄電池用格子体を改良するものである。
【0007】
本発明に係る鉛蓄電池用格子体では、耳部から遠い側の中骨は横中骨がなく縦中骨のみで構成されていることを特徴とする。
【0008】
この場合、横中骨がなく縦中骨のみで構成されている区間は、縦枠骨を含んで格子体横幅の30%の区間であることが好ましい。
【0009】
このように鉛蓄電池用格子体を、耳部から遠い側の中骨は、横中骨がなく縦中骨のみで構成されていると、蓄電池の充放電により格子体が伸びた時に、耳部から遠い側では横中骨がないため結果的に伸びの力が横方向に逃げ、縦骨が変形して上枠骨を上方に押し上げることがなくなる。これにより、本発明の鉛蓄電池用格子体は、充放電中に上方向に伸び、対極のストラップに当たって短絡するのを防止することができる。
【0010】
このような縦骨が変形して上枠骨を上方に押し上げる可能性のある区間は、縦枠骨を含んで格子体横幅の30%の区間であるので、この区間の横中骨をなくすことにより、上記の効果を得ることができる。
【0011】
【発明の実施の形態】
以下、本発明の実施の形態の一例を図1を参照して詳細の説明する。なお、前述した図2と対応する部分には、同一符号を付けて示している。
【0012】
本例の鉛蓄電池用格子体1は、耳部5から遠い側の中骨4a,4bは、横中骨4bがなく縦中骨4aのみで構成されている。この横中骨4bがなく縦中骨4aのみで構成されている区間は、縦枠骨3aを含んで格子体横幅の30%の区間となっている。
【0013】
このような格子体1を使用した95D31形蓄電池にて、JIS過充電寿命試験を実施した。その結果、図2に示す従来の格子体1を使用した従来品の95D31形蓄電池の場合、その寿命回数が11回であるのに対し、図1に示す本発明の格子体1を使用した本発明品の95D31形蓄電池の場合、寿命回数は13回であった。このときの寿命原因は、従来品が格子体1の伸びによるストラップと格子体の短絡であるのに対し、本発明品は格子体1の劣化による寿命であった。

本発明に係る鉛蓄電池用格子体は、耳部から遠い側の中骨を、横中骨がなく縦中骨のみで構成しているので、蓄電池の充放電により格子体が伸びた時に、耳部から遠い側では横中骨がないため結果的に伸びの力が横方向に逃げ、縦骨が変形して上枠骨を上方に押し上げることがなくなる。これにより、本発明の鉛蓄電池用格子体は、充放電中に上方向に伸び、対極のストラップに当たって短絡するのを防止することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a grid for a lead storage battery.
[0002]
[Prior art]
As shown in FIG. 2, the conventional lead-acid battery lattice body 1 has an upper frame bone 2a, vertical frame bones 3a and 3b, a lower frame bone 2b, a vertical middle bone 4a, and a horizontal middle bone 4b. In this structure, the ear portion 5 is provided at a position from one side of 2a (for example, see Patent Document 1).
[0003]
[Patent Document 1]
Japanese Patent No. 2805910 (FIG. 1)
[0004]
[Problems to be solved by the invention]
However, the conventional lead-acid battery using the lead-acid battery grid body 1 has a problem that the grid body 1 extends upward during charging / discharging, and hits the counter electrode strap to cause a short circuit.
[0005]
SUMMARY OF THE INVENTION An object of the present invention is to provide a grid for a lead-acid battery, which extends upward during charging and discharging and can prevent a short circuit from being caused by hitting a strap of a counter electrode.
[0006]
[Means for Solving the Problems]
The present invention improves a lead-acid battery lattice body having an upper frame bone, a vertical frame bone, a lower frame bone, a vertical medial bone, and a lateral medial bone, and having an ear portion provided in the upper frame bone.
[0007]
The grid for a lead storage battery according to the present invention is characterized in that the medial bones on the side remote from the ears are composed of only longitudinal medial bones without lateral medial bones.
[0008]
In this case, it is preferable that the section composed of only the vertical medial bone without the horizontal medial bone is a section including the vertical frame bone and having a width of 30% of the lattice width.
[0009]
In this way, when the grid for a lead-acid battery is formed of only vertical medial bones without lateral medial bones, the medial bones on the side remote from the ears have a lug when the lattice is elongated by charging and discharging of the storage battery. On the side farther from the side, there is no lateral middle bone, and as a result, the stretching force escapes in the lateral direction, and the vertical bone is not deformed and the upper frame bone is not pushed upward. Thereby, the grid body for a lead storage battery of the present invention can be prevented from extending upward during charging / discharging and being short-circuited by hitting the strap of the counter electrode.
[0010]
The section where such a vertical bone may deform and push the upper frame bone upward is a section including the vertical frame bone which is 30% of the width of the lattice body. Thereby, the above effects can be obtained.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an example of an embodiment of the present invention will be described in detail with reference to FIG. Parts corresponding to those in FIG. 2 described above are denoted by the same reference numerals.
[0012]
In the lead-acid battery lattice body 1 of this example, the middle bones 4a and 4b on the side remote from the ears 5 are formed of only the vertical middle bone 4a without the horizontal middle bone 4b. The section which does not include the horizontal medial bone 4b but includes only the vertical medial bone 4a is a section including the vertical frame bone 3a and having a width of 30% of the lattice width.
[0013]
A JIS overcharge life test was performed on a 95D31 type storage battery using such a lattice body 1. As a result, in the case of the conventional 95D31 type storage battery using the conventional grid 1 shown in FIG. 2, the life thereof is 11 times, while the battery using the grid 1 of the present invention shown in FIG. 1 is 11 times. In the case of the invented 95D31 type storage battery, the life cycle was 13 times. The cause of the life at this time was a short circuit between the strap and the lattice body due to the elongation of the lattice body 1 in the conventional product, whereas the product of the present invention was a life due to the deterioration of the lattice body 1.
[0014]

[0015]
【The invention's effect】
In the lead-acid battery grid according to the present invention, the middle bone far from the ear portion is composed of only the vertical middle bone without the horizontal middle bone. On the side farther from the part, there is no lateral middle bone, so that the stretching force escapes in the lateral direction, and the vertical bone is not deformed and the upper frame bone is not pushed upward. Thereby, the grid body for a lead storage battery of the present invention can be prevented from extending upward during charging and discharging, and being short-circuited by hitting the strap of the counter electrode.
[0016]
The section in which such a vertical bone is deformed and may push the upper frame bone upward is a section including the vertical frame bone and having a width of 30% of the width of the lattice body. Thereby, the above effects can be obtained.
