<p>An explosion-proof cover plate assembly including a cover plate (15), an insulation element (11), an explosion-proof diaphragm (8), a pulling plate (5) and an assembling base (17), in which a chamber (28) communicated from upside to downside is provided on the assembling base (17), an annular sealed groove is provided in the chamber (28). With laminated and pressed tightly connection fashion, the edge of the explosion-proof diaphragm (8) and the edge of the cover plate (20) are clasped and fixed in the annular sealed groove, and the cover plate (15) and the explosion-proof diaphragm (8) are connected electrically each other to form a decompression room (13), the cover plate (20) and the explosion-proof diaphragm (8) are insulated from the assembling base (17) via the insulation element (11), and the explosion-proof diaphragm (8) is electrically connected to the pulling plate (5) beneath thereof which is supported against on the assembling base (17) and is insulated from the assembling base (17) via the insulation element(11), so that the explosion-proof diaphragm(8) is broken and disconnect to the pulling plate(5) when the press applied to it is higher than a setting value. An explosion-proof battery using the above stated explosion-proof cover plate assembly is provided.</p> |
