Abstract

PURPOSE:To usually close a gas venting groove by a recess and surely operate the gas vent by pressing a cylindrical positive terminal having a recess in the lower periphery and whose upper end is closed in the opening of a cover through a ring-shaped elastic valve having a gas venting groove. CONSTITUTION:A doughnut-shaped hollow disk 4 is mounted by seal-mold 3 in a cover of sealed alkaline storage battery, and a rubber gasket 2 with a gas venting groove 11 in its inside is fixed in the inner periphery of the disk 4. A cylindrical positive terminal 1 having a recess 5 in the lower periphery and whose upper end is closed is pressed in the gasket 2 so that the recess 5 if in contact with the inside of the gasket 2 t form a safety vent. Although the gas venting groove 11 of the gasket 2 is usually closed by the recess 5, when internal pressure increased, the hollow disk 4 is deformed and the gas venting groove 11 is opened to vent gas. Therefore, the structure of the safety vent is simplified and its operation is surely performed.

The case (a) consists of a large circular plate 6 having a seal mold 3 on the outermost periphery and a gas exhaust hole in the center, and a convex small circular plate 7 that also serves as an anode terminal and has a gas exhaust hole in the center. A rubber block 8 is sandwiched between them, and the large circular plate 6 and the small circular plate 7 are welded by spot welding from the soil part. In such a structure, if the welding is too weak, the small disk 7 will come off. On the other hand, if the weld is too strong, a hole will be left in the weld, making it impossible to seal the battery.

The present invention aims to solve the above-mentioned problems.Means for solving the problemsIn order to achieve this object, as shown in Fig. 1, the lid is shaped like a donut. A hollow disc 4 is used, and a seal mold 3 is provided on the outermost periphery of the hollow disc 4 as before.
A rubber gasket 2 that acts as a safety valve is also attached around the circular hole.A gas venting groove 11 is provided on the inside of this rubber gasket 2, and the anode terminal 1 is a cylinder with a recess 5 at the lower peripheral edge and a closed upper end. The recess 5 is press-fitted inside the rubber packing 2, and the recess normally seals the gas vent groove 11.
