Capacitor with visual explosion-proof device for computer

The utility model discloses a computer-used capacitor with a visual explosion-proof device, the outer side of a capacitor core group of the capacitor is half surrounded by an outer insulation shell, the outer insulation shell is provided with a gap at one conductive end, an inner insulation shell is arranged in the gap, and the inner insulation shell is fixed with the capacitor core group. When the capacitor is deformed at high temperature, the copper foil sheet can be easily pulled and broken, so that the power failure of the capacitor is realized, the capacitor is prevented from explosion caused by further high temperature, and the explosion can be effectively prevented. And secondly, the copper foil is visible, so that the state of the copper foil can be observed by naked eyes, the capacitors with normal explosion-proof functions can be screened, the use of the capacitors with the explosion-proof functions disappearing due to the abnormal copper foil is avoided, and whether the capacitors are available or
