And the two-side edge margin metallized film (2) is provided with a metallization layer (4) that is at a middle part of the two-side edge margin metallized film (2); and there are distances between the metallization layer (4) and two ends of the two-side edge margin metallized film (2), wherein the distance ranges are from 1 to 3 mm. According to the invention, the capacitor has advantages of simplified winding technology, small volume, low cost, and good electrical performance.
Description
Technical field
The present invention relates to a kind of capacitor, relate in particular to a kind of intermediately remained border one layer metallization membrane capacitance.
Background technology
At present; The capacitor dielectric of the internal series-connection structure that adopts is an organic film; Metal polar plate is metal forming (a particularly aluminium foil); Concrete structure is: one deck organic film, one deck aluminium foil (comprising two aluminium foil strip of leaving a blank in the middle of not contacting), one deck organic film, one deck aluminium foil, four layers of formation altogether.Because of metal foil thickness is bigger, be generally tens of microns, even surpass the thickness of organic film, the capacitor volume of making is bigger, and cost is higher.
Summary of the invention
The objective of the invention is deficiency, provide a kind of volume preferable intermediately remained border one layer metallization membrane capacitance to prior art.
The technical scheme that the present invention solves existing internal series-connection capacitor shortcoming is: a kind of intermediately remained border one layer metallization membrane capacitance; It comprises capacitor body, and said capacitor body comprises that one deck intermediately remained border metalized film (1) of coiling and one deck both sides of the edge stay limit metalized film (2).
As the further improvement of such scheme, said intermediately remained border metalized film (1) is provided with two metal layers (3), and said two metal layers (3) are positioned at the same side of said intermediately remained border metalized film (1), and said two metal layers (3) at interval.Preferably, the spacing distance scope of said two metal layers (3) is 2 ~ 6mm.
Further improvement as such scheme; Said both sides of the edge stay limit metalized film (2) to be provided with metal layer (4); Said metal layer (4) is positioned at the middle part that limit metalized film (2) are stayed in said both sides of the edge, and said metal layer (4) stays the two ends of limit metalized film (2) to have distance with said both sides of the edge.Preferably, to stay the distance range at limit metalized film (2) two ends be 1 ~ 3mm to the said both sides of the edge of said metal layer (4) distance.
As the further improvement of such scheme, said intermediately remained border metalized film (1) and said both sides of the edge stay limit metalized film (2) to be the single face metalized film.Preferably; Said intermediately remained border metalized film (1) and said both sides of the edge stay the width of limit metalized film (2) unequal; The width of said intermediately remained border metalized film (1) stays the width of limit metalized film (2) greater than said both sides of the edge, and limit metalized film (2) align center is stayed in said intermediately remained border metalized film (1) and said both sides of the edge.Preferably, it is 2 ~ 6mm that the width of said intermediately remained border metalized film (1) stays the width range of limit metalized film (2) greater than said both sides of the edge.
Said intermediately remained border one layer metallization membrane capacitance; Use metallization technology; Capacitor body stays limit single face metallizing film winding to form by one deck intermediately remained border single face metalized film and one deck both sides of the edge, therefore has the characteristics that winding process is simplified, volume is little, cost is low, electrical property is good.

。Embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
As shown in Figure 1, the capacitor body of intermediately remained border one layer metallization membrane capacitance mainly stays limit metalized film 2 to reel by one deck intermediately remained border metalized film 1 and one deck both sides of the edge and forms.Both sides are metal layer 3 on the intermediately remained border metalized film 1, the width of the about 2 ~ 6mm in the middle part no metal level of leaving a blank, and promptly the epilamellar metal layer of this layer is two metal tapes that do not communicate.Both sides of the edge stay that metal layer 4 is positioned in the middle of the film on the limit metalized film 2, and respectively the have an appointment width of 1 ~ 3mm of both sides of the edge does not have metallic region.The double-layer metallization film is the single face metalized film.And double-layer metallization film width is unequal, and intermediately remained border metalized film 1 width stays limit metalized film 2 about 2 ~ 6mm, two membranes align center greater than both sides of the edge.
The present invention has following advantage:
1, metallization layer thickness has only and is zero point more than zero microns, tens of micron thickness of contrast metal forming, the reducing by a small margin of volume of having realized internal series-connection structure capacitive device.
2, provide cost savings after the metallization.
3, need reel two-layer organic film and two-layer aluminium foil of original structure, existing architecture is the double-layer metallization film, production technology is simplified.
4, metallized capacitor has self-healing function, after capacitor comes out partial breakdown, can return to original performance, but metal foil capacitor does not just have this performance, and the electrical property of capacitor is improved.
The foregoing description only is used for further specifying the present invention and is a kind of intermediately remained border one layer metallization membrane capacitance; But the present invention is not limited to embodiment; Every foundation technical spirit of the present invention all falls in the protection range of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
