It was preventing this. Further, the splash-proof tube and ceramic or polypropylene,
A porous filter made of synthetic resin such as polyethylene was housed in the liquid outlet plug at the same time to improve liquid overflow resistance.

。In addition, the liquid outlet plug using a gas permeable membrane has excellent performance in terms of liquid overflow resistance because the gas permeable membrane blocks liquid.
Because it uses a gas-permeable membrane of about 0 μm, there is no particular problem when it is installed in a car as a liquid outlet plug for an automotive lead-acid battery because the charging voltage is controlled by the regulator and the charging current is suppressed. Although this does not occur, when the regulator is damaged or when supplementary charging is performed, a large current flows and the gas permeable membrane does not have the ability to discharge gas, so excessive pressure is applied to the storage battery, causing damage to the storage battery. The gas permeable membrane was damaged and could no longer function as a liquid port plug.

A second exhaust port 3 is provided on the top surface, and inside there is a splash-proof cylinder 4 having a labyrinth structure, a filter 5 made of a porous material of ceramic or synthetic resin such as polyethylene, polyzolopyrene, etc., and a large number of pores with a pore diameter of about 10 μm. A gas permeable membrane 6 made of a porous film of polytetrafluoroethylene or polyethylene having the following properties and a gas permeable membrane holder 7 for housing the gas permeable membrane 6 are built in. An exhaust hole 8 is provided in the center of the gas permeable membrane 6, and a gasket 9 is provided on the outside of the upper part of the liquid port body 1.

Gas generated from the electrode plate group 12 during charging is discharged to the outside of the storage battery through the first exhaust port 2, the exhaust hole 8, and the second exhaust port 3 of the liquid port body 1. Splashes and water vapor of the electrolytic solution 13 mixed into the gas are filtered through the splash-proof cylinder 4 having a labyrinth in the liquid spout body 1 and the filter 5, and then re-filtered through the gas permeable membrane 6. The electrolytic solution 13 and water vapor are prevented from leaking outside the storage battery.

The aperture ratio expressed as the ratio (A//B) to the inner diameter of the gas permeable membrane 6, that is, the effective diameter B of the gas permeable membrane 6, is defined to be 1% to 20%.

８の直径を２ｔｍｎ以内に規定した。Figure 4 shows the relationship between the exhaust hole diameter of the gas permeable membrane 6 and the hot liquid critical vibration acceleration, which determined the critical hot liquid acceleration with respect to vibration. Since the liquid critical vibration acceleration decreases rapidly, the diameter of the exhaust hole 8 is specified to be within 2 tmn.

%, the hot liquid critical vibration acceleration will drop significantly.
The upper limit of the aperture ratio was defined as 20. In addition, when the aperture ratio becomes 1% or less, the possible charging current decreases significantly, so we consider the possible charging current value of 12 A when the aperture ratio is 1% as a practically sufficient charging current value, and set the lower limit of the aperture ratio to 1%. stipulated.
