【考案の詳細な説明】
産業上の利用分野
本考案は、密閉形鉛蓄電池の改良に関するもの
である。[Detailed Description of the Invention] Industrial Application Field The present invention relates to improvement of a sealed lead-acid battery.
従来の技術
従来の密閉形鉛蓄電池の安全弁構造は、ほとん
どが、弁筒７にゴムキヤツプ６をつけて、このキ
ヤツプの上に当て板５を配した構造（第３図）と
なつている。BACKGROUND OF THE INVENTION Most conventional safety valve structures for sealed lead-acid batteries have a structure in which a rubber cap 6 is attached to a valve barrel 7, and a backing plate 5 is placed on top of this cap (FIG. 3).
考案が解決しようとする問題点
従来のような安全弁構造では、弁筒７は電槽４
または蓋を成形する際に一体成形する必要があ
り、また、弁筒７の径はある程度の寸法が必要な
ため、密閉形鉛蓄電池の軽薄短小化、特に薄形化
に関して、弁筒７の寸法を確保しなければならな
いことは大きな障害となる。Problems to be solved by the invention In the conventional safety valve structure, the valve cylinder 7 is connected to the battery case 4.
Alternatively, when molding the lid, it is necessary to integrally mold the lid, and the diameter of the valve cylinder 7 must have a certain size. The need to secure this is a major obstacle.
問題点を解決するための手段
電池を薄形化するためには、安全弁部分も薄く
する必要がある。このため、本考案では、柔軟性
を有した電槽材料を用いて、安全弁を設けるべき
部分に存在する２つの電槽側壁のうち、一方の先
端部を内側に折りまげ、更にその先端を外側に折
り曲げて、もう一方の電槽側壁に当接し、この当
接部分にシリコーンオイル等のオイルを塗布して
安全弁とした。Measures to solve the problem In order to make the battery thinner, it is necessary to make the safety valve part thinner as well. For this reason, in the present invention, by using a flexible battery case material, one of the two side walls of the battery case existing in the area where the safety valve is to be installed is folded inward, and the tip is bent outward. Bend it to make contact with the other side wall of the battery case, and apply oil such as silicone oil to this contact part to create a safety valve.
作 用
電池が静置されている状態では、第１図ａに示
したように、折り曲げられた電槽側壁の他方への
弾力によつて、気密が保持されている。Operation When the battery is left still, airtightness is maintained by the elasticity of the bent side wall of the battery case toward the other side, as shown in FIG. 1a.
また、充電され、電池内部の内圧が上昇した場
合には、第１図ｂに示すように、当接された２つ
の側壁が内圧のために開き、排気が行なわれる。 Further, when the battery is charged and the internal pressure inside the battery increases, the two side walls that are in contact with each other open due to the internal pressure, as shown in FIG. 1b, and exhaust air is performed.
実施例
第１図に本考案による密閉形鉛蓄電池の安全弁
部分の断面図を示す。第１図ａは弁が閉じている
場合を示す。Embodiment FIG. 1 shows a sectional view of the safety valve portion of a sealed lead-acid battery according to the present invention. Figure 1a shows the case when the valve is closed.
１は折り曲げられた方の電槽側壁、２は折り曲
げない方の電槽側壁、３はオイル塗付部分であ
る。 1 is the bent side wall of the battery case, 2 is the unbent side wall of the battery case, and 3 is the oiled part.
本考案の弁部分の場合、電槽厚みの約４倍の厚
さで弁部分が構成されるため、電池の薄形化の方
向にマツチしている。 In the case of the valve part of the present invention, the valve part is constructed with a thickness approximately four times the thickness of the battery case, so it is suitable for making the battery thinner.
考案の効果
本考案では、従来の、密閉形鉛蓄電池では達成
し得なかつた薄い寸法で、安全弁が構成できるた
め、電池の薄形化が可能となつた。Effects of the invention With this invention, the safety valve can be constructed with a thinner dimension that could not be achieved with conventional sealed lead-acid batteries, making it possible to make the battery thinner.
第１図は本考案による密閉形鉛蓄電池の安全部
分を示すもので、ａは閉弁時の断面図、ｂは開弁
時の断面図、第２図は従来の密閉形鉛蓄電池の安
全弁部分の断面図である。
１……折り曲げられた方の電槽側壁、２……折
り曲げない方の電槽側壁。
Figure 1 shows the safety part of the sealed lead-acid battery according to the present invention, where a is a cross-sectional view when the valve is closed, b is a cross-sectional view when the valve is open, and Figure 2 is the safety valve part of a conventional sealed lead-acid battery. FIG. 1... Side wall of the battery case that is bent, 2... Side wall of the battery case that is not bent.
Claims (1)
鉛蓄電池、相対する２つの電槽部分の一方の先端
部を内側に折りまげ、更にその先端側を外側に折
り曲げ、この２つの折れ曲がつた部分の弾力性に
よつて安全弁機能を有したことを特徴とする密閉
形鉛蓄電池。 A sealed lead-acid battery whose battery case is made of flexible synthetic resin is made by folding one end of the two opposing battery case parts inward, and then bending the end side outward. A sealed lead-acid battery characterized by having a safety valve function due to the elasticity of the ivy portion.
