Disclosing a kind of metal metallized safety film with new patent metal metallized safety film, it is by arranging square lattice portion side in the middle of film
Resistance region, is respectively provided with selvage portion and screen band relief area, arranges insurance array, net at lattice portion sheet resistance intra-zone in both sides
Sheet resistance region, lattice portion should have insurance mutually with selvage portion, screen band relief area, thus improve its anti-explosion safety performance.But, should
Metallized film constructions is not particularly suited for direct current capacitors, is included on electric automobile or electric bus the DC capacitor used
Device.
Utility model content
The purpose of this utility model is to provide a kind of direct current capacitors being applicable on electric automobile or electric bus to prevent
Quick-fried metalized film, by the explosion-proof task that lost efficacy after blown fuse during spontaneous recovery, solves existing direct current capacitors metal
Change that film is inflammable and explosive, the shortcoming of poor reliability, to overcome the deficiency in the presence of prior art.
The technical scheme in the invention for solving the technical problem is: a kind of capacitor from explosion metalized film, including insulation
Dielectric layer, the metallized film layers on insulating medium layer, described metallized film layers is slit into first by rectangle without plating differentiation
Row's conduction rectangular grid, second row conduction rectangular grid, selvage portion；Each conduction lattice of first row conduction rectangular grid are all with adjacent the
Two rows conduct electricity rectangular grid conduction lattice between be provided with electric fuse, between each conduction lattice and the selvage portion of first row conduction rectangular grid
It is provided with electric fuse, so that the rectangular conductive of conduction lattice and the second row conduction rectangular grid of rectangle in first row conduction rectangular grid
Lattice, selvage portion connect；In second row conduction rectangular grid, adjacent rectangular conductive lattice are connected by electric fuse, second row conduction rectangle
The side of lattice is screen band.
The conduction lattice of conduction lattice and the second row conduction rectangular grid of first row conduction rectangular grid are staggered arrangement.
