Vertical, automatic-cutoff and explosion-proof capacitor

Abstract

The invention discloses a vertical, automatic-cutoff and explosion-proof capacitor. The vertical, automatic-cutoff and explosion-proof capacitor comprises an outer shell, a core, a sealant cover, a first lead and a second lead, wherein the sealant cover is matched with the outer shell and is used for packaging the core in the outer shell, the core is provided with a first electrode post and a second electrode post, a hole passage is arranged in the first electrode post, a conductive sleeve and an expansion sleeve are arranged in the hole passage, the conductive sleeve is made of a conductive material, the expansion sleeve is made of a thermal expansion material, an insulation layer wraps a peripheral surface of the first lead and is arranged between two ends of the first lead, one end of the first lead penetrates through the sealant cover, the first lead and the insulation layer extend into the hole passage, the conductive sleeve is arranged at one side of the insulation layer and sleeves the first lead, the expansion sleeve is arranged at one side, far away from the insulation layer, of the conductive sleeve and sleeves the first lead, and one end of the second lead penetrates through the sealant cover, extends into the outer shell and is fixed with the second electrode post. By the vertical, automatic-cutoff and explosion-proof capacitor, the phenomenon of high-temperature explosion of the capacitor is effectively solved, and the application safety of the capacitor is improved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a vertical self-cutting explosion-proof capacitor. Background technique [0002] Capacitors are energy storage elements. During its use, when abnormal heat is generated inside it, it will inevitably cause the internal pressure to increase, causing the capacitor shell to deform, expand and even burst. Contents of the invention [0003] Based on the technical problems in the above background technology, the present invention proposes a vertical self-cutting explosion-proof capacitor. [0004] The invention proposes a vertical self-cutting explosion-proof capacitor, including: an outer shell, a core arranged inside the outer shell, a sealant cover that cooperates with the outer shell to encapsulate the core inside the outer shell, and a first lead wire and a second lead where: [0005] The end of the core close to the sealant cover has a first electrode column and a second ...
