Embodiment 1
[0046] Embodiment one, see Figure 1 to Figure 5As shown, a folded capacitor core, especially a double-sided metallized horizontal folded film capacitor, includes a double-sided metallized film 10, and the double-sided metallized film 10 includes an insulating film 1, and the surfaces on both sides of the insulating film 1 The first metallized surface 2 and the second metallized surface 5 are respectively provided, and the longitudinal edges of the two sides of the double-sided metallized film 10 are respectively provided with the first blank margin 11 and the second blank margin exposing the surface of the insulating film 1 12. The first margin 11 and the second margin 12 are distributed from left to right; the longitudinal edge of the first margin 11 is also provided with a first metallized edge 4, and the first metallized edge 4 and the first metallized The surface 2 is separated; the longitudinal edge of the second margin 12 is also provided with a second metallized edge 7...
Embodiment 2
[0055] Embodiment two, see Figure 7 to Figure 10 As shown, a folded capacitor core, especially a folded capacitor core with dislocation and stacking of multiple films, includes a double-sided metallized film 10, and the double-sided metallized film 10 includes an insulating film 1, and the insulating film 1 has two sides The side surfaces are respectively provided with a first metallized surface 2 and a second metallized surface 5, and the longitudinal edges of the two side surfaces of the double-sided metallized film 10 are respectively provided with a first margin 11 and a second blank edge 11 exposing the surface of the insulating film 1. Margins 12, the first margin 11 and the second margin 12 are distributed one left and one right; the double-sided metallized film 10 is provided with more than two sheets, and the opposite faces of two adjacent double-sided metallized films 10 are the same Each double-sided metallized film 10 is superimposed and folded horizontally to for...
Embodiment 3
[0063] Embodiment three, see Figure 13 to Figure 17 As shown, a folded capacitor core, especially a foil-type organic film capacitor, includes an insulating film 1, a first metal foil 2 and a second metal foil 3, and the first metal foil 2 and the second metal foil 3 Stagger left and right, and make the left and right sides of the insulating film 1 expose blank margins respectively, and the blank margins are respectively arranged on the surfaces of both sides of the insulating film 1; the first metal foil 2 and the second metal foil 3 are respectively stacked on the insulating film 1 After the surfaces on both sides are reciprocated and folded together horizontally (for the direction of folding, see Figure 16 (indicated by the arrow B in middle B) to form a folded piece. The left and right ends of the folded piece are respectively provided with a first terminal 4 and a second terminal 5. The first terminal 4 is in conductive contact with the first metal foil 2, and the secon...
