Description
Technical field
The utility model relates to a kind of capacitor, relates 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.
The utility model content
The purpose of the utility model is the deficiency to prior art, provides a kind of volume preferable intermediately remained border one layer metallization membrane capacitance.
The technical scheme that the utility model 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
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model 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 utility model, and be not used in qualification the utility model.
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 utlity model 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.
It is a kind of intermediately remained border one layer metallization membrane capacitance that the foregoing description only is used for further specifying the utility model; But the utility model is not limited to embodiment; Every technical spirit according to the utility model all falls in the protection range of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did.
