The beneficial effects of the utility model are: evaporated film capacitor has self-healing ability, nonpolarity, insulation impedance is very high, realizes capacitor more microminiaturized.
On the basis of technique scheme, the utility model can also do following improvement.
Further technical scheme, described the first evaporated film comprises the first evaporation metal part and the first non-evaporation metal part, described the first evaporation metal part is placed in a side on the first evaporated film, described the first non-evaporation metal part is placed in opposite side on the first evaporated film, described the second evaporated film comprises the second evaporation metal part and the second non-evaporation metal part, described the second evaporation metal part is placed in one end on the second evaporated film, and described the second non-evaporation metal part is placed in opposite side on the second evaporated film.
Further technical scheme, described the first evaporation metal part comprises the first horizontal shape evaporation metal and the first strip evaporation metal, described the first strip evaporation metal is placed in the first evaporation metal part one side, described the first horizontal shape evaporation metal is provided with multiple, and be all placed in the first strip evaporation metal one side and vertical with the first strip evaporation metal, described the second evaporation metal part is set to strip, described the first horizontal shape evaporation metal and the second evaporation metal formation active electrode that partly overlaps.
Further technical scheme, described the second evaporation metal part comprises the second horizontal shape evaporation metal and the second strip evaporation metal, described the second strip evaporation metal is placed in the second evaporation metal part one side, described the second horizontal shape evaporation metal is provided with multiple, and be all placed in the second strip evaporation metal one side and vertical with the second strip evaporation metal, described the first evaporation metal part is set to strip, described the second horizontal shape evaporation metal and the first evaporation metal formation active electrode that partly overlaps.
Adopt the beneficial effect of above-mentioned further scheme to be: when evaporated film is guaranteed electrode length, to cut apart electrode, increased and ensured safe performance.
