Double-seal anti-falling super capacitor cover plate

Abstract

The invention discloses a double-seal anti-falling super capacitor cover plate. The cover plate comprises a rubber layer, a laminated phenolic resin paperboard is adhered to the lower part of the rubber layer, and through holes A are formed in the two ends of the top of the laminated phenolic resin paperboard and the two ends of the top of the rubber layer correspondingly; pure aluminum rivets arearranged on the inner sides of the through holes A correspondingly, annular soldering lugs are installed on the outer sides of the pure aluminum rivets correspondingly, rubber gaskets are arranged onthe tops of the annular soldering lugs correspondingly, and the tops of the rubber gaskets are tightly attached to the laminated phenolic resin paperboard. According to the invention, the cover plateis provided with the integrated pure aluminum rivets and the soldering lugs, so the possibility of loosening of the pure aluminum rivet is avoided, the soldering lugs combined with the pure aluminumrivets are prevented from falling off, and the service live of a capacitor is prolonged while the stability is guaranteed; according to the double-sealing anti-falling super capacitor cover plate, through the soldering lugs, the rubber gaskets, the annular grooves and the rivets, the double sealing is effectively achieved, the possibility of electrolyte leakage is greatly reduced, and the servicelife of the capacitor is further prolonged.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to a double-seal anti-falling off supercapacitor cover plate. Background technique [0002] With the rapid development of electronic information technology, the upgrading speed of digital electronic products is getting faster and faster. The production and sales of consumer electronic products, mainly flat-panel TVs, notebook computers, digital cameras and other products, continue to grow, which drives the growth of the capacitor industry. The difficult cover plate on the capacitor is one of the necessary parts. [0003] The sealing performance of the traditional capacitor cover plate is poor, and electrolyte leakage is prone to occur, and the traditional rivet and the annular soldering piece are not of an integrated structure, which is prone to loosening during use, causing the annular welding piece combined with the rivet to fall off. Therefore, the design of the present invent...
