Description
Technical field
The present invention relates to capacitor technology field more particularly to a kind of capacitor metalized membrane structures.
Background technique
Thin film capacitor is a kind of capacitor of excellent performance due to having many excellent characteristics.It main
Etc. property it is as follows：Nonpolarity, insulation impedance is very high, and frequency characteristic is excellent, and dielectric loss very little.Common thin film capacitor its
Preparation method is that metal foil is made together with winding after plastic film overlapping as electrode.After capacitor rolls, need to be to rolling after
End face carry out metal spraying processing so that the inner ring winding layer of metalized film and outer ring winding layer form the metal electrode face of an entirety.
The side end face area of the metal layer of existing metalized film is smaller and smooth, and metalized film metal layer end is being sprayed
It is small with gilding layer adhesive force when golden, it is easy to produce centre and falls off prevent metal layer increases capacitor from forming equipotential
The internal resistance of device.
Summary of the invention
Present invention aim to address above-mentioned deficiencies, provide a kind of capacitor metalized membrane structure.
A kind of capacitor metalized membrane structure provided by the invention, including metallic film ontology, the metallic film sheet
Body includes insulation film, metal layer, and the metal layer is attached to insulation film upper surface, the metal spraying end of the metal layer and insulation
Film end is concordant, is equipped with one section between the other end of the metal layer and the other end of insulation film and stays border area；The metal
The metal spraying end end face of layer is equipped with groove.
Further, the metal spraying end thickness of the metal layer is greater than the thickness of the other end.
Further, the insulation film uses polypropylene film.
Further, the double-layer staggered arrangement of metallic film ontology.
A kind of capacitor metalized membrane structure provided by the invention, by metal layer end face be arranged groove, pass through by
The metal spraying end of metal layer thickeies, and increases the contact area of end face, improves adhesive force, prevents post-production from metal spraying occur and fall off.
The present invention improves the metal spraying adhesive force of capacitor metalized film, reduces the internal resistance of capacitor, improves capacitor
Product quality.
Detailed description of the invention：
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the schematic diagram of interlaced arrangement of the invention.
Specific embodiment
Below by embodiment to further instruction of the present invention, the embodiment of the present invention is with technical solution of the present invention
Premised under implemented, the detailed implementation method and specific operation process are given, but protection scope of the present invention is unlimited
In following embodiments：
As shown in Figures 1 and 2, a kind of capacitor metalized membrane structure provided by the invention, including metallic film ontology 1, institute
Stating metallic film ontology 1 includes insulation film 11, metal layer 12, and the metal layer 12 is attached to 11 upper surface of insulation film, institute
The metal spraying end 121 for stating metal layer 12 is concordant with 11 end of insulation film, the other end and the insulation film 11 of the metal layer 12
One section, which is equipped with, between the other end stays border area 13；121 end face of metal spraying end of the metal layer 12 is equipped with groove 122.
Further, 121 thickness of metal spraying end of the metal layer 12 is greater than the thickness of the other end.
Further, the insulation film 11 uses polypropylene film.
Further, the double-layer staggered arrangement of metallic film ontology 1.
A kind of capacitor metalized membrane structure provided by the invention, by metal layer end face be arranged groove, pass through by
The metal spraying end of metal layer thickeies, and increases the contact area of end face, improves adhesive force, prevents post-production from metal spraying occur and fall off.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case where without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended power
Benefit requires rather than above description limits, it is intended that all by what is fallen within the meaning and scope of the equivalent elements of the claims
Variation is included within the present invention.
