Description
Technical field
The utility model relates to capacitor area, is specifically related to a kind of thin-film capacitor core and film capacitor.
Background technology
Fig. 1 shows the capacitor body that a kind of vertical cut of the prior art stays limit film, and the thin layer 1 of this capacitor body and the trimming of the coat of metal 2 are straight flange.Owing to staying limit to be straight flange, the adhesive force therefore between gilding layer and capacitor body is little, mechanical strength compared with low, container withstanding current capability is poor, loss is large.
Fig. 2 shows the trimming schematic diagram of another kind of capacitor body of the prior art.As shown in Figure 2, the thin layer 1 of this capacitor body and the limit of staying of the coat of metal 2 are straight flange, and the another side of the coat of metal adopts Wave-cut, has crest and trough, easily damages the end face of film, increase loss during welding; Or need gilding layer to thicken cost increase.It also has the shortcoming that adhesive force is little, mechanical strength is lower, container withstanding current capability is poor, loss is large between thin layer and the coat of metal.
Summary of the invention
The utility model provides a kind of thin-film capacitor core and film capacitor, to solve the problem that in prior art, between gilding layer and capacitor body, mechanical strength is low, loss is large.
For solving the problem, as an aspect of the present utility model, provide a kind of thin-film capacitor core, comprise electrode section, electrode section comprises: thin layer, comprises the first limit and Second Edge that are oppositely arranged, and wherein, Second Edge is the first curve; And the coat of metal, be formed on thin layer, and the coat of metal has the 3rd limit and the 4th limit that are oppositely arranged, 3rd limit overlaps with the first limit, 4th limit is the second curve, and the first curve is identical with the second curve, and there is between the first curve and the second curve constant spacing stays limit to be formed.
Further, spacing is 0.5-2mm.
Further, thin-film capacitor core comprises two electrode section, and two electrode section are arranged abreast.
Further, thin layer is polypropylene film.
Further, the first curve is what be connected in sequence by multi-section circular arc.
Further, the opening direction of adjacent two circular arcs is contrary.
Further, the first limit and the 3rd limit are straight flange.
As another aspect of the present utility model, provide a kind of film capacitor, comprise lead-in wire and above-mentioned thin-film capacitor core, wire bonds is on the coat of metal of thin-film capacitor core.
Because the first curve and the second curve have employed curve form, therefore, add the effective contact area between gilding layer and metal coating, improve the adhesive force between gilding layer and fuse, solve the problem of gilding layer mechanical strength in prior art, and add the withstanding current capability of capacitor.
