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、鉛蓄電池用格子体は、上枠骨、縦枠骨、下枠骨、縦・横中骨を有する各骨で構成する格子体で形成されている。該格子体は、上枠骨、縦枠骨、下枠骨が縦・横中骨より太い構造であった。
【0003】
【発明が解決しようとする課題】
しかしながら、上記の如き従来の鉛蓄電池用格子体を使用した鉛蓄電池では、格子体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。
【0004】
本発明の目的は、格子体が充放電中に伸びても、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。
【0005】
【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、縦中骨を有する鉛蓄電池用格子体を対象とする。
【0006】
本発明に係る鉛蓄電池用格子体では、
前記上枠骨の太さをA、前記縦枠骨の太さをB、前記下枠骨の太さをC、前記縦中骨の太さをDとしたとき、
A≧B≧D>C
の関係を有することを特徴とする。
【0007】
このように鉛蓄電池用格子体の太さを、A≧B≧D>C、即ち、上枠骨≧縦枠骨≧縦中骨>下枠骨とすると、蓄電池の充放電により格子体が伸びた時に、下枠骨が他の枠骨より細いため、伸びの力の方向は下向きになり、結果的に下枠骨が下向きに変形する。これにより、本発明の鉛蓄電池用格子体は、対極のストラップに当たり短絡しないように格子体の伸びの方向が規制され、上部で短絡するのを防止することができる。
【0008】
【発明の実施の形態】
図1は、本発明に係る鉛蓄電池用格子体の実施の形態の一例の正面図である。

この鉛蓄電池用格子体は、上枠骨1、1対の縦枠骨2、下枠骨3、縦(横)中骨4,耳部5で構成されている。この図では、横中骨4の表示を省略している。
【0010】
本例では、これら骨1〜4の太さ(断面積)を、
上枠骨1の太さA=2.5 mm2 
縦枠骨2の太さB=2.0 mm2

縦(横)中骨4の太さD=1.5 mm2 
とし、即ちA>B>D>Cとした鉛蓄電池用格子体にペーストを充填して極板を構成し、この極板を用いて作成した55D23形蓄電池にて、JIS過充電寿命試験を実施した。
【0011】
その結果、従来の格子体による極板を使用した55D23形蓄電池の場合、その寿命回数が7回であるのに対し、本発明の格子体による極板で構成した55D23形蓄電池の場合、寿命回数は9回であった。
【0012】
このときの寿命原因は、従来品が格子体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、本発明の格子体による極板で構成した55D23形蓄電池では格子体の劣化による寿命であった。

【発明の効果】
本発明に係る鉛蓄電池用格子は、上枠骨の太さをA、前記縦枠骨の太さをB、前記下枠骨の太さをC、前記縦中骨の太さをDとしたとき、各骨の太さ(断面積)の関係を、A≧B≧D>Cとしたので、鉛蓄電池の充放電により格子体が伸びた時に、一番細い下枠骨に対する伸びの力の方向は下向きになり、結果的に下枠骨が下向きに変形することになる。これにより、本発明の鉛蓄電池用格子体によれば、格子体が充放電中に伸びても、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]
2. Description of the Related Art Conventionally, a grid for a lead-acid battery is formed of a grid composed of bones having an upper frame, a vertical frame, a lower frame, and a vertical and horizontal middle bone. The lattice body had a structure in which the upper frame, the vertical frame, and the lower frame were thicker than the vertical and horizontal medial bones.
[0003]
[Problems to be solved by the invention]
However, the conventional lead-acid battery using the lead-acid battery grid as described above has a problem that the grid extends upward during charging and discharging, hits the strap of the counter electrode, and causes a short circuit.
[0004]
SUMMARY OF THE INVENTION An object of the present invention is to provide a grid for a lead-acid battery that can prevent a short circuit from being applied to a counter electrode strap even when the grid extends during charging and discharging.
[0005]
[Means for Solving the Problems]
The present invention is directed to a grid for a lead-acid battery having an upper frame, a vertical frame, a lower frame, and a vertical medial bone.
[0006]
In the grid for a lead storage battery according to the present invention,
When the thickness of the upper frame bone is A, the thickness of the vertical frame bone is B, the thickness of the lower frame bone is C, and the thickness of the vertical middle bone is D,
A ≧ B ≧ D> C
Is characterized by the following relationship.
[0007]
As described above, when the thickness of the grid for a lead-acid battery is A ≧ B ≧ D> C, that is, upper frame bone ≧ vertical frame bone ≧ vertical middle bone> lower frame bone, the grid body is elongated by charging and discharging of the storage battery. When the lower frame bone is thinner than the other frame bones, the direction of the extension force is directed downward, and as a result, the lower frame bone is deformed downward. Thus, in the lead-acid battery grid body of the present invention, the direction of elongation of the grid body is regulated so as not to hit the strap of the counter electrode and cause a short circuit, and it is possible to prevent a short circuit at the upper part.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a front view of an example of an embodiment of a grid for a lead-acid battery according to the present invention.
[0009]
The grid for a lead-acid battery includes an upper frame 1, a pair of vertical frames 2, a lower frame 3, a vertical (horizontal) middle bone 4, and an ear 5. In this figure, the display of the lateral middle bone 4 is omitted.
[0010]
In this example, the thickness (cross-sectional area) of these bones 1 to 4 is
The thickness A of the upper frame bone 1 = 2.5 mm 2 ,
The thickness B of the vertical frame bone 2 = 2.0 mm 2 ,
The thickness C of the lower frame 3 is 1.0 mm 2 ,
Thickness D of vertical (horizontal) middle bone 4 = 1.5 mm 2
That is, a paste is filled in a grid for a lead-acid battery with A>B>D> C to form an electrode plate, and a JIS overcharge life test is performed on a 55D23 type storage battery made using this electrode plate. did.
[0011]
As a result, in the case of the 55D23 type storage battery using the conventional grid-based electrode, the lifetime was 7 times, whereas in the case of the 55D23 type storage battery configured with the grid-based electrode of the present invention, the lifespan was 7 times. Was 9 times.
[0012]
The cause of the life at this time is a short-circuit between the strap and the lattice body due to the elongation of the lattice body in the conventional product, whereas the 55D23 type storage battery composed of the electrode plate of the lattice body of the present invention has a life due to the deterioration of the lattice body. Was.
[0013]
[Table 1]
Figure 2004063153
In the above example, the relationship between the thicknesses of the bones of the lattice is described as A>B>D> C, but the present invention is not limited to this, and the relationship between the thicknesses of the bones of the lattice is It is sufficient that A ≧ B ≧ D> C.
[0014]
【The invention's effect】
In the lead-acid battery grid according to the present invention, the thickness of the upper frame bone is A, the thickness of the vertical frame bone is B, the thickness of the lower frame bone is C, and the thickness of the vertical middle bone is D. At this time, since the relation of the thickness (cross-sectional area) of each bone is set as A ≧ B ≧ D> C, when the lattice body is extended by charging / discharging of the lead storage battery, the force of the elongation to the thinnest lower frame bone is obtained. The direction is downward, resulting in the lower frame bone deforming downward. Thus, according to the grid for a lead storage battery of the present invention, even if the grid extends during charging / discharging, it is possible to prevent a short circuit from hitting the strap of the counter electrode.
