Abstract
The utility model discloses a kind of not containing the metal metallized safety film of fuse structure, the metallised electrode layer comprising organic thin-film carrier and formed after organic film carrier surface evaporation metal, the blank that a lateral edges of organic film carrier surface is provided with non-evaporation metal polarizing electrode layer stays limit; The surface of organic film carrier is provided with the blank striped of metallised electrode layer described in many non-evaporations be parallel to each other, and one end of blank striped arises from blank and stays limit and the other end terminates in 3mm ~ 10mm place, edge that distance metallised electrode layer stays limit relative with blank.The utility model is by being improved to metallised electrode layer syndeton by traditional fuse connection structure, and this syndeton can not affect running current passes through, electrode resistance can not increase, the capacitor withstanding current capability that this metal metallized safety film of employing is produced can not decline, and avoid capacitor and occur excessive self-healing because self-healing energy is excessive and then the problem that forever punctures occurs, improve the fail safe of capacitor proof voltage.
Description
Technical field
The utility model relates to a kind of metal metallized safety film, particularly relates to a kind of not containing the metal metallized safety film of fuse structure.
Background technology
The metal metallized safety film of current application, its metal layer (also claiming metallised electrode layer) surface is divided into multiple independently fritter by many through blank stripeds, connect with superfine fuse between adjacent isles, when a certain fritter generation partial breakdown, metal fuse fuses immediately, breakdown area and normal region are kept apart, guarantees that capacitor does not affect by breakdown point.The fuse structure of this traditional metal metallized safety film can effectively isolation breakdown region and normal region, there is safe enough, but this fuse structure changes the transmission path of operating current, add electrode resistance, reduce capacitor (namely adopting the capacitor that metal metallized safety film is produced) withstanding current capability, it is normally worked and causes certain influence.
Utility model content
The purpose of this utility model is just that providing a kind of to solve the problem both had had the metal metallized safety film not containing fuse structure that security performance does not affect its normal work.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of not containing the metal metallized safety film of fuse structure, the metallised electrode layer comprising organic thin-film carrier and formed after described organic film carrier surface evaporation metal, the blank that a lateral edges of described organic film carrier surface is provided with metallised electrode layer described in non-evaporation stays limit; The surface of described organic film carrier is provided with the blank striped of metallised electrode layer described in many non-evaporations be parallel to each other, and one end of described blank striped arises from described blank and stays limit and the other end terminates in 3mm ~ 10mm place, edge apart from described metallised electrode layer stays limit relative with described blank.
In said structure, whole metallised electrode layer is not divided into the fritter separated completely by blank striped, but be divided into the fritter of multiple metallised electrode layer contact having 3mm ~ 10mm wide, form conduction by the metallised electrode layer that 3mm ~ 10mm is wide between adjacent fritter to connect, this structure instead of traditional fuse structure.
As preferably, described blank striped and described blank stay the angle between limit to be 80 ~ 90 °; The width of described blank striped is 0.1mm ~ 2mm; Described organic film carrier is polypropylene, polyphenylene sulfide, polyester, polystyrene or Merlon and its thickness is 1 μm ~ 25 μm.
Above-mentioned mm is millimeter, μm is micron.
The beneficial effects of the utility model are:
The utility model is by being improved to the wide metallised electrode layer syndeton of 3mm ~ 10mm by traditional fuse connection structure, and this syndeton can not affect running current passes through, electrode resistance can not increase, capacitor withstanding current capability can not decline, and avoids fuse structure and reduces capacitor (namely adopting the capacitor that this metal metallized safety film is produced) withstanding current capability and affect the problem of the normal work of metal metallized safety film; Avoid fuse reduce capacitor (namely adopting the capacitor that this metal metallized safety film is produced) withstanding current capability and affect the problem of the normal work of metal metallized safety film; Simultaneously, when capacitor internal generation self-healing, blank striped prevents electric current directly to transmit to self-healing point, self-healing electric current can only first collect to metallised electrode layer edge, arrive self-healing point through metallised electrode layer edge again, current delivery approach is extended, and the metallised electrode layer sheet resistance of prolongation inhibits self-healing fault offset, avoid capacitor to occur because self-healing energy is excessive the problem that excessive self-healing and then generation forever puncture improve the fail safe of capacitor proof voltage.

Fig. 2 is main TV structure schematic diagram when normally not working containing the metal metallized safety film of fuse structure described in the utility model;
Main TV structure schematic diagram when Fig. 3 is the metal metallized safety film generation self-healing not containing fuse structure described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, described in the utility model not containing the metallised electrode layer 2 that the metal metallized safety film of fuse structure comprises organic thin-film carrier 1 and formed after the surperficial evaporation metal of organic film carrier 1, organic film carrier 1 is for polypropylene, polyphenylene sulfide, polyester, polystyrene or Merlon and its thickness is 1 μm ~ 25 μm, and the blank that the lateral edges on organic film carrier 1 surface is provided with non-evaporation metal polarizing electrode layer 2 stays limit 4; The surface of organic film carrier 1 is provided with the blank striped 3 of the non-evaporation metal polarizing electrode layer 2 that many are parallel to each other, and one end of blank striped 3 arises from blank and stays limit 4 and the other end terminates in 3mm ~ 10mm place, edge that distance metallised electrode layer 2 stays limit 4 relative with blank; The width of blank striped 3 is 0.1mm ~ 2mm; Blank striped 3 and blank stay the angle between limit 4 to be 80 ~ 90 °.
As shown in Figure 2, when the capacitor adopting this metal metallized safety film to produce normally works, operating current transmits according to operating current direction A, this sense of current and blank striped 3 keeping parallelism, therefore blank striped 3 can not affect the transmission of running current, and electrode resistance can not increase.
As shown in Figure 3, when there is local self-healing in capacitor internal, blank striped 3 prevents self-healing electric current to the direct transmission path of self-healing point 5, self-healing electric current can only transmit according to self-healing sense of current B, self-healing current path is extended, and the resistance extending the metallised electrode layer 2 on path can play the effect suppressing self-healing electric current.By controlling metallised electrode layer 2 and the width of blank striped 3 and the sheet resistance value of metallised electrode layer 2; can by self-healing energy hole can meet metallised electrode layer 2 completely self-healing and self-healing point can be avoided again to occur in the scope of excessive self-healing because energy is excessive simultaneously; thus avoid the phenomenon that product forever punctures and occur, protect metal metallized safety film.
Above-described embodiment is preferred embodiment of the present utility model; it is not the restriction to technical solutions of the utility model; as long as without the technical scheme that creative work can realize on the basis of above-described embodiment, all should be considered as falling within the scope of the rights protection of the utility model patent.
