Abstract
The utility model belongs to the technical field of capacitor, in particular relates to an organic thin-film capacitor. The organic thin-film capacitor solves the technical problems in the prior art that the design is not reasonable, the service life is short and the like. The organic thin-film capacitor comprises a winding core body and a packaging layer coated outside the winding core body, wherein one side of the winding core body is provided with two radial leading-out wires which are parallel to each other. The organic thin-film capacitor is characterized in that the winding core body comprises external polypropylene thin film and internal polypropylene thin film which are sequentially arranged from outside to inside, upper and lower surfaces of the external polypropylene thin film are respectively provided with evaporated metal layers, the thickness of the external polypropylene thin film ranges from 7 to 9 mu m, and the thickness of the internal polypropylene thin film ranges from 7 to 9 mu m. Compared with the prior art, the organic thin-film capacitor has the advantage strong practicality, can effectively reduce the failure rate of capacitors, and prolongs the service life of capacitors.
Description
Technical field
The utility model belongs to the capacitor technology field, especially relates to a kind of organic film condenser.
Background technology
Organic film condenser is to do medium with the organic plastics film, do electrode with metal forming or metallized film, make by winding method, along with making rapid progress of electronic information technology, the update speed of digital electronic goods is more and more faster, with panel TV, notebook computer, the products such as digital camera are main consumer electronics product volume of production and marketing sustainable growth, driven the capacitor industrial growth, the storage electric charge that the electrode that conductor approaching by two and mutually insulated is made forms and the device capacitor of electric energy are one of a large amount of electronic components that use in the electronic equipment, be widely used in handing over every straight-through in the circuit, coupling, bypass, filtering, resonant tank, power conversion, the aspects such as control.For the failure rate that can reduce organic film condenser with improve useful life, for this reason, people have carried out long-term exploration, have proposed various solutions.
For example, Chinese patent literature discloses a kind of non-inductive organic film capacitor [application number: CN200720044417.3], it comprises take the two-layer stacked organic polyester film of metallization as medium coiling fuse, be fixedly connected on the inserts between fuse both ends of the surface and pin, shell, shell and the fuse vertical with the fuse axis, is provided with interior encapsulated layer outside fuse.In addition, Chinese patent literature also discloses another kind of capacitor [application number: 201020698211.4], include body, sleeve, end cap and binding post, one end of sleeve is socketed on the body, the other end of sleeve connects end cap, binding post links to each other with body and stretches out in outside the end cap, it is characterized in that: the spinosity sheet also is set between described body and the sleeve, the thorn sheet includes inserted sheet and the plug that is connected on this inserted sheet, be provided with flexure strip on the plug, one end of flexure strip is connected on this plug, and the other end of flexure strip sticks up to turning up towards the inserted sheet lateral direction, and the inner chamber of sleeve is provided with the socket that can match with plug; The both sides of inserted sheet respectively interval are provided with a plurality of hangnails, above-mentioned two schemes has improved prior art to a certain extent, but it still can't solve the high technical problem of capacitor failure rate thoroughly the capacitor here, and useful life is short and virtually increased use cost.
The utility model content
The purpose of this utility model is for the problems referred to above, and a kind of organic film condenser that can effectively reduce failure rate and the long service life of capacitor is provided.
For achieving the above object, the utility model has adopted following technical proposal: this organic film condenser comprises the coiling core body and is covered in the encapsulated layer of this winding core external body, side at the coiling core body has two radially lead-out wires that are parallel to each other, it is characterized in that, described coiling core body comprises outer polypropylene film and the interior polypropylene film that sets gradually from outside to inside, be respectively equipped with evaporated metal layer on the upper and lower surface of polypropylene film outside, described outer polypropylene film thickness is 7～9 μ m, and described interior polypropylene film thickness is 7～9 μ m.Obviously, the utility model design is more reasonable, and structure is simpler, and is practical, and in addition, the failure rate that it can reduce capacitor has effectively prolonged useful life virtually, meets the trend of current social technical development.
As preferably, in above-mentioned organic film condenser, the described radially spacing between the lead-out wire is 5mm.
As preferably, in above-mentioned organic film condenser, described encapsulated layer is fire retarding epoxide resin.Has the good advantage of anti-dissolubility and moisture-proof.
Compared with prior art, the advantage of this organic film condenser is: it is more reasonable to design, and structure is simpler, and is practical, and in addition, the failure rate that it can reduce capacitor has effectively prolonged useful life virtually, meets the trend of current social technical development.
Description of drawings
Fig. 1 is the structural representation that the utility model provides.
