FIG. 3 is a view showing the outer shape of a general storage battery, 1 is a battery case, 2 is a lid, and 3 is a liquid spout provided on the lid. FIG. 1 shows a cross-sectional view of the explosion-proof liquid spout in this example. Incidentally, FIG. 2 is an enlarged view of the fitting portion of FIG. 1 in more detail. A gas permeable membrane 8 made of polytetrafluoroethylene film is provided on the inner top surface of the cap-shaped joined body 7 made of a synthetic resin molded product.
After being welded by ultrasonic waves, the protrusion 9 of the joined body is fitted into the recess 11 of the liquid spout main body 3 and then the ceramic filter 4 is inserted. In this case, ceramic filter 4
While heat is applied to, the surrounding resin is melted and the space between the filter and the resin is eliminated to ensure airtight reliability. At this time, since the film is inside the bottom of the bonded body, there is no fear of melting the film. Further, in order to prevent the electrolytic solution from splashing to some extent, the splash-proof plate 5 is fitted in the liquid spout main body 3. If there is some space between the inside of the top surface of the liquid mouth plug body 3 and the top surface of the joined body 7, the exhaust hole 6 provided in the liquid mouth stopper 3 and the exhaust provided in the joined body 7. The positional relationship with the holes 10 may be different, but when the space is eliminated, it is necessary to align the positions of the holes for exhausting air.
発明の効果 以上のように本発明の構成によれば、次のような効果を
得ることができる。Effects of the Invention According to the configuration of the present invention as described above, the following effects can be obtained.
(1)ガス排出流路にガス透過膜を用いているため、電解
液を通さず、ガスのみ流れるので溢液が無く、耐溢液性
能に優れている。(1) Since a gas permeable membrane is used in the gas discharge passage, only the gas does not flow through the electrolyte solution, and there is no overflow, and the overflow resistance is excellent.
(2)接合体を用いるため、ガス透過膜を傷付けることな
く液口栓本体へ取り付けることが出来、膜を保護するこ
とができる。更にこの接合体の突条部と液口栓本体の凹
条部とにより両者を嵌合したうえフィルターを嵌着する
ため、かなり信頼の高い気密性を得る事が出来、排気孔
以外からの溢液が生じ無い。(2) Since the bonded body is used, it can be attached to the liquid mouth plug body without damaging the gas permeable membrane, and the membrane can be protected. Furthermore, since both the protrusion and the recess of the liquid mouth plug body are fitted together and the filter is fitted, it is possible to obtain fairly reliable airtightness and to prevent overflow from other than the exhaust hole. No liquid is produced.
(3)液口栓本体の排気孔と接合体の排気孔との位置をず
らしているため外部からの不純物等によるガス透過膜及
びフィルターの目づまりが無く、安全性に優れている。(3) Since the positions of the exhaust holes of the liquid mouth plug main body and the exhaust holes of the joined body are shifted, the gas permeable membrane and the filter are not clogged by impurities from the outside, and the safety is excellent.
このように、ガス透過膜をセラミック製フィルターと併
用するとともに、ガス透過膜を備えたキャップ形接合体
の液口栓本体への接合を凹凸部による嵌合によって行っ
ているので極めて耐溢液性能を高くすることができる。In this way, the gas permeable membrane is used in combination with the ceramic filter, and the cap-shaped joint with the gas permeable membrane is joined to the body of the liquid mouth plug by the concavo-convex part. Can be higher.
また、キャップ形接合体の天面の排気孔の位置と液口栓
本体の天面に設けられた排気孔の位置をずらしているの
で、液口栓外部からの侵入物によって前記接合体の天面
の内側に固定したガス透過膜が容易に破損したり目づま
りすることを防止することができ、安全性に優れた高信
頼性の蓄電池を市場に供給することができる。Further, since the position of the exhaust hole on the top surface of the cap-type joined body and the position of the exhaust hole provided on the top surface of the liquid mouth stopper body are displaced, the ceiling of the joined body is prevented by an intruder from the outside of the liquid mouth stopper. It is possible to prevent the gas permeable membrane fixed inside the surface from being easily damaged or clogged, and it is possible to supply a highly reliable storage battery with excellent safety to the market.
