TH13303B - Closed battery and closed assembly - Google Patents

Abstract

DC60 (04/05/41) The purpose of this invention is to provide a closed battery that can release pressure under In it quickly and at the same time disconnect the electric current to protect itself from Effectively increasing the temperature and detonation so that it can ensure the safety. And its reliability When the internal pressure is higher due to a short circuit Overcharging, reverse charging Or something similar on such a completely closed battery. The formation of the tongue component 5, where its center is off-center to the center of the metal base plate 1, forms a small cavity 3 with a large portion surrounding the circumference of the tongue assembly 5 when the internal pressure of the battery. More The fifth tongue component was lifted like Flattened with metal foil 2 from the slanted pivot section 4 to cut the splicing wire 6 or to loosen the brass connector 8 from the splicing wire 6 so the current is reliably cut and the metal foil can be burned. IRS can be stable and precise at the specified pressure to Form the valve opening part 7 in this way so that the internal gas of the battery can be discharged so the battery can be prevented from explosion. The purpose of this invention is to provide a closed battery that can release pressure under In it quickly and at the same time disconnect the electric current to protect itself from Effectively increasing the temperature and detonation so that it can ensure the safety.

The formation of the tongue component 5, where its center is off-center to the center of the metal base plate 1, forms a small cavity 3 with a large portion surrounding the circumference of the tongue assembly 5 when the internal pressure of the battery. More The five tongue components are also raised in pieces. Flattened with metal foil 2 from the slanted pivot section 4 to cut the connecting wire 6, or to make the brass weld 8 from the connecting wire 6, thus reliably cutting the current. Was made to be able to be burnt stably and precisely at the rated pressure to Form a valve opening 7 in this way so that the internal gas of the battery can be discharged, so the battery can be prevented from explosion.
