Abstract
The utility model relates to a part used in a thin-film capacitor of an electronic component, in particular to a metalized safety film. The technical scheme is as following: the metalized safety film comprises grid units and is characterized in that the metalized safety film further comprises an evaporated thickened zone which is a complete coating; the evaporated thickened zone is located at one side of the safety film while a non-evaporated margin-reserved zone is located at the other side of the safety film; the evaporated thickened zone is immediately adjacent to a metalized evaporated zone; and the metalized safety film further comprises evaporated isolation zone penetrating belts distributed in a manner that the evaporated isolation zone penetrating belts penetrate from the non-evaporated margin-reserved zone towards the evaporated thickened zone. The beneficial effects of the metalized safety film with the adoption of the aforementioned technical scheme are as following: the certain grid units are designed in the thin-film conducting originating direction, an undivided unit complete coating mode is employed in the conducting terminating direction, and vertical non-evaporated isolation belts which are in complete or incomplete conduction are arranged simultaneously within a certain interval, so that the safety performance is improved; and thanks to a relatively large complete coating area, the requirements of the safety performance of the capacitor can be met and the service life of the capacitor is also taken into account simultaneously.
Description
Technical field
The utility model relates to the film capacitor material of electronic devices and components, relates in particular to metal metallized safety film.
Background technology
Can use metallized film in the film capacitor as core group material, wherein basement membrane is as condenser dielectric, and metallization coating is as capacitor plate.Metallized film can be divided into common metal film and metal metallized safety film.The coating of common metal film is monoblock, and does not carry out any cutting apart the centre, is divided into evaporation district and evaporation district not on the metal metallized safety film, and whole coating is cut apart by evaporation district not, connects and have tiny evaporation conductive strips in cutting apart.Tiny evaporation conductive strips play a key effect as the security performance of release mechanism to capacitor, each divided little deposition unit plays a key effect to the capacitor serviceability, so the mesh design form of metal metallized safety film plays a key effect to the performance of capacitor.Exist in the market multiple safety diaphragm mesh design form, it is rare that market product can be accomplished capacitor safe and serviceability to optimize very much on mesh design, because fail safe and serviceability are conflicts in the mesh design, pay attention to fail safe and just can't take into account serviceability, exactly because also this reason, metallized safety film capacitor serviceability in industry standard requires to be starkly lower than the normal film capacitor.
At present the mesh design safety diaphragm all adopts full breadth bar shaped or rhombus, square net project organization, behind the withstand voltage not enough medium breakdown phenomenon of the local appearance of capacitor, around the deposition unit of breakdown point place, the fusing of can under the breakdown current effect, gasifying of four evaporation conductive strips, thereby this minimum unit and other cell isolation, cut off current channel, this element is discarded, avoided puncturing the further expansion of energy, cause product forever to puncture and lost efficacy or large tracts of land puncture melting short circuit, therefore guaranteed just the security performance of product.But also be the mesh design because of this full breadth, it is larger to give up cellar area after product punctures, and the condenser capacity loss is also large, and the relative normal film capacitor of life of product can significantly shorten.
The utility model content
The utility model purpose: the utility model can make capacitor under the prerequisite that possesses the requirement of safety diaphragm product safety performance in order to take into account capacitor safe and serviceability requirement, and the product serviceability is near the normal film capacitor.
In order to reach as above purpose, the utility model is taked following technical scheme: metal metallized safety film, comprise grid cell, and it is characterized in that: also comprising is the metallization evaporation district of complete coating.
The further technical scheme of the utility model is: also comprise the evaporation thickened area, described evaporation thickened area is positioned at a side of safety diaphragm, and the opposite side of safety diaphragm stays the border area for evaporation not.
The further technical scheme of the utility model is: described evaporation thickened area next-door neighbour metallization evaporation district.
The further technical scheme of the utility model is: described metallization evaporation district comprises separates border area and abjoint grid district, and described separation border area is comprised of evaporation conductive strips border area and the interval, evaporation isolated area border area of lineal layout; Described abjoint grid district is comprised of evaporation isolated area grid regions and the evaporation conductive grid district of distributed in grid.
The further technical scheme of the utility model is: never also comprising, evaporation stays the border area to run through band towards evaporation thickened area vertical direction evaporation isolated area complete or that not exclusively distribute.
The further technical scheme of the utility model is: described evaporation isolated area runs through with more than one group.
Adopt as above the utility model of technical scheme, has following beneficial effect: the design of this New Grid, on film conduction origin direction, designed certain grid cell, and finish to have adopted the not complete coating mode of cutting unit on the direction in conduction, simultaneously in a spacer segment, the vertical direction that is provided with complete conducting or not exclusively conducting is the evaporation isolation strip not, has promoted security performance.More than design because the complete cladding region in larger zone can satisfy the security performance requirement of capacitor, has taken into account again simultaneously product useful life.
