Problems solved by technology

[0002] Microcapacitors have a relatively simple structure due to their small size, and their packaging materials do not have high mechanical strength, and due to their small size, it is difficult to set up an explosion-proof structure
When the circuit or the capacitor itself fails and causes the capacitor to overheat or cause the filling material inside the capacitor to burn, it is very likely to cause the capacitor to explode.

Abstract

The invention discloses a mini-type anti-explosion fireproof capacitor which comprises a thin film core, a leading-out terminal and an outer shell. The thin film core and the leading-out terminal are wrapped by the outer shell, and a fireproof bag is further arranged in the outer shell and filled with fire extinguishing agents. When the mini-type anti-explosion fireproof capacitor explodes, the fireproof bag in the outer shell is cracked under the explosion pressure effect, the fire extinguishing agents in the fireproof bag can be diffused along with the explosion gas and attached to the surface of the mini-type anti-explosion fireproof capacitor and the surface of peripheral circuits, and therefore the fireproofing and flame retardant effects are achieved.

Description

technical field [0001] The invention relates to a miniature explosion-proof and fireproof capacitor, which belongs to the technical field of capacitor manufacturing. Background technique [0002] Microcapacitors have a relatively simple structure due to their small size, and their packaging materials do not have high mechanical strength, and due to their small size, it is difficult to set up an explosion-proof structure. And when the circuit or the capacitor itself fails and causes the capacitor to overheat or cause the filling material inside the capacitor to burn, it is very likely to cause the capacitor to explode. The explosion will not only generate sparks and cause a fire, but the circuit may be short-circuited after the explosion, which increases the chance of a fire. Therefore, it is necessary to design an explosion-proof and fire-proof structure according to the characteristics of microcapacitors, which can effectively reduce the probability of fire caused by capac...
