Title:
EXPLOSION-PROOF CELL
Document Type and Number:
Japanese Patent JPH01189857
Kind Code:
A
Abstract:
PURPOSE:To prevent the deflection and damage of a flexible thin plate during assembling by providing a gap between the flexible thin plate and a sealing plate and providing a gap between a thermal deformation member and the upper plate section of the main body portion of a terminal plate or between the thermal deformation member and the flexible thin plate. CONSTITUTION:The periphery section of a flexible thin plate 40 and a circular packing 30 are pinched by the collar-shaped periphery section 22 of a terminal plate 20 and a sealing plate 10, a gap is provided between the flexible thin plate 40 and the sealing plate 10, a circular thermal deformation member 50 is made low in height, a gap is provided between the thermal deformation member 50 and the upper plate section of the main body portion 21 of the terminal plate 20 or between the thermal deformation member 50 and the flexible thin plate 40. The upward deflection and damage of the flexible thin plate 40 during the assembling of a sealing body 1 are prevented, the dispersion of the operating pressure of an explosion-proof device and the leakage of an electrolyte during storage are prevented.
