【発明の詳細な説明】 産業上の利用分野 本発明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 applications The present invention relates to improvements in sealed lead-acid batteries.
従来の技術
近年、密閉形鉛蓄電池は小形軽量化並びに高性能化の要

と言う欠点があった。Conventional technology In recent years, there has been a strong demand for sealed lead-acid batteries to be smaller, lighter, and have higher performance. It has become necessary to increase Conventionally, safety valves for sealed lead-acid batteries are made by attaching a cap-shaped synthetic rubber to a cylindrical lunch box, so the protrusion at the exhaust hole has to be made high to prevent it from falling off, and the safety valve has a large volume. There was a drawback to having it exclusively.

閉形鉛蓄電池であり、従来の円筒状の弁当にキャップ状
の合成ゴムを装着するタイプの安全弁が脱落防止の為に
必要とした高い排気孔部突条が不必要となるので、安全
弁の体積を減少さすことができたものである。Means for Solving the Problems The present invention is a sealed lead-acid battery in which a safety valve consisting of a flexible canopy part and a ventilated annular body part is fixed to an exhaust hole part. This eliminates the need for a high protrusion on the exhaust hole, which is required to prevent the safety valve of the type that attaches a synthetic rubber cap to the lunch box, so the volume of the safety valve can be reduced. .

It is a diagram. 1
2 is a battery cover, 2 is an exhaust hole provided in the battery cover, 3 is a protruding exhaust hole, 4 is an annular body having ventilation, and 5 is a flexible canopy. A canopy part 5 is integrated with the upper surface of the annular body part 4 to constitute a safety valve 7, which is installed so as to cover the exhaust hole 2. The annular body 4 and the canopy part 5 may be integrally molded, or may be molded separately and then integrated by adhesion or welding; in this embodiment, they are integrated by adhesion. 0 The annular body having air permeability may be a porous body such as alumina sintered body, foamed polyethylene resin, foamed acrylic resin, mullite beads, etc., or at least one of PP@ fat, acrylic resin, ABS resin, etc. It may be provided with pores having the above-mentioned air permeability.

Possible methods include welding and fitting. In this embodiment, it is fixed with adhesive. When the internal pressure of the battery increases due to gas generated inside, the canopy of the safety valve swells, and the gas reaches the annular body through the gap between the exhaust hole protrusion and the canopy, causing the annular body to have air permeability. The internal pressure of the battery is prevented from increasing because it passes through and is released to the outside. Note that there is no difference in performance even without the exhaust hole protrusion.
