Abstract
The utility model provides a large current shock resistant capacitor, comprising a lead wire strip, a cover plate and a terminal fixed on the cover plate. The lead wire strip is in riveted joint with the terminal, the cover plate is circular, and a thimble is arranged in the center of the cover plate and enables a plurality of stiffeners to be dispersed to the edge of the cover plate. The large current shock resistant capacitor is characterized in that the laser spot welding is carried out at the riveting position of the lead wire strip and the terminal, the large current shock resistant capacitor can work safely when a large current passes, and enables the service life of the capacitor to be prolonged.
Description
Technical field
The utility model has related to a kind of capacitor of anti-heavy current impact, belongs to field of capacitor manufacture.
Background technology
At present, along with the development of large power supply and frequency converter, as the aluminium electrolytic capacitor of filtering and energy storage, more and more higher to its anti-high current impulse withstanding capability, former cold-press process: adopt a pneumatic compression devices, the lead-in wire bar is colded pressing on the cover plate terminal, because two metals are physical contacts, there is contact resistance in its surface, (generally at 0.2-0.4m Ω), by large electric current the time, riveted joint place heating causes the anodal fusing when work of lead-in wire bar.
Summary of the invention
In order to overcome shortcoming of the prior art, the utility model provides a kind of capacitor of anti-heavy current impact, comprise lead-in wire bar, cover plate and fixing on the cover board terminal, described lead-in wire bar and terminal riveted joint, described cover plate is circular, there is a thimble at described cover plate center, divides many reinforcements that shed to the edge of described cover plate by thimble, and it is characterized in that: laser spot welding is carried out in riveted joint place at described lead-in wire bar and terminal.
The utility model provides a kind of capacitor of anti-heavy current impact, carries out laser spot welding on the basis of lead-in wire bar and terminal riveted joint again, and energy trouble free service by large electric current the time has prolonged useful life of capacitor.
