Title:
EXPLOSION-PROOF CELL
Document Type and Number:
Japanese Patent JPH01189855
Kind Code:
A
Abstract:
PURPOSE:To prevent the deflection of a flexible thin plate during assembling by making the inner diameter of a circular packing larger than the outer diameter of the main body portion of a terminal plate, arranging it below the flexible thin plate, and folding the collar-shaped periphery section of the terminal plate obliquely upward. CONSTITUTION:The opening edge of a sealing plate 10 is folded, a folded edge 12 is caulked, the collar-shaped periphery section 22 of a terminal plate 20 is pressed. Since the inner diameter of a circular packing 30 is made larger than the outer diameter of the main body portion 21 of the terminal plate 20 and the collar-shaped periphery section 22 of the terminal plate 20 is folded obliquely upward, an outward force in the radial direction in addition to a downward force is applied to the circular packing 30, the circular packing 30 is sealed on the outside in the radial direction from the main body portion 21 of the terminal plate 20. An outward force in the radial direction is applied to the periphery section of a flexible thin plate 40 accordingly, the flexible thin plate 40 is pulled to the periphery section side, and the center section is prevented from being flexed upward.
