The utility model provides a low heat radiation metallization film possessing multiple protection functions, used for the manufacturing of capacitors and comprising a metal coating and a carrier adhered to the metal coating. The metal coating comprises a plurality of metal coating modules; adjacent metal coating modules are separated through gaps, and part of adjacent metal coating modules are in electric connection through fuses. Part of the metal coating modules include a plurality of metal coating units; adjacent metal coating units are separated through gaps, and adjacent metal coating modules are in electric connection through fuses. The utility model provides the low heat radiation metallization film possessing multiple protection functions which can minimize heat radiation, increase a service life and maintain a good performance after multitime self-healing of the low heat radiation metallization film.
Description
Technical field
The utility model relates to a kind of low heating and has the metallized film of multiple protection functions.
Background technology
The metal metallized safety film capacitor is the widely used a kind of discrete electronic components of industry such as electrical equipment, electronic information, microelectronics.As shown in Figure 1; The structure of metallized film is: metallized film comprises metallization coating and the carrier that is used for adhesion metal coating; Metallization coating comprises the number of metal coating unit a that is divided into by many gap b, and coat of metal unit a is the box-shaped structure, and number of metal coating unit a forms network structure; With adopting fuse c to connect between the close coat of metal unit a, again double-layer metallization film stack coiled capacitor.Owing to all adopt fuse c to connect between the close coat of metal unit a, make that the quantity of the interior fuse c of unit are is on the high side, metal metallized safety film capacitor caloric value in the energising use is bigger than normal, influences its quality and useful life.In addition, when capacitor occurred puncturing through current overload, fuse c was vaporized under the effect of instantaneous large-current; Make breakdown coat of metal unit a and other normal region isolate, capacitor still can keep normal performance, and promptly capacitor can be realized self-healing; During the less generation of self-healing, capacitor only loses the electrode area of the coat of metal unit a that occurs puncturing, and the capacitor volume loss is less; But at trystate or when using for a long time, the frequent self-healing of capacitor makes effectively reducing over against area of capacitor, and condenser capacity also can reduce rapidly; So when the structure of design metallized film, consider, when capacitor is switched on; Fuse c should bear shoving about 100A; Fuse c can in time move when guaranteeing the partial breakdown short circuit again, and loss is tried one's best fewly effectively over against area in the time of also will guaranteeing self-healing, is a problem demanding prompt solution.
The utility model content
The utility model provides a kind of low heating and has the metallized film of multiple protection functions, can reduce heating, improves the life-span, can realize repeatedly still keeping good performance after the self-healing when the utility model.
The utility model solves the problems of the technologies described above through following technical scheme; The utility model proposes a kind of low heating and has the metallized film of multiple protection functions, is used for the manufacturing of capacitor, comprises the coat of metal and the carrier that adheres to the said coat of metal; The said coat of metal comprises number of metal coating module; Break off through the gap between the adjacent said coat of metal module, be electrically connected through fuse between the adjacent said coat of metal module of part, the said coat of metal module of part comprises number of metal coating unit; Break off through the gap between the adjacent said coat of metal unit, be electrically connected through fuse between the adjacent said coat of metal unit.
Preferably, the said coat of metal module next-door neighbour who comprises said coat of metal unit does not comprise the said coat of metal module of said coat of metal unit.
Based on disclosing of above technical scheme, the utlity model has following beneficial effect:
Reduced the quantity of fuse in the unit are; Can reduce heating and increase its useful life,, coat of metal unit isolated through blow out fuse when capacitor transships locally when breakdown; At this moment; Area area with respect to coat of metal module of isolating is less, and loss effectively less than normal over against area makes the utility model after experiencing repeatedly self-healing process, still keep good performance.

Embodiment
Following embodiment 1 and Fig. 2 of combining is described further the utility model:
The utility model proposes a kind of low heating and has the metallized film of multiple protection functions, is used for the manufacturing of capacitor, comprises the carrier of the coat of metal and adhesion metal coating; The coat of metal comprises number of metal coating module 1, breaks off through gap 2 between the adjacent metal coating module 1, is electrically connected through fuse 3 between the part adjacent metal coating module 1; Compared to prior art, so design can reduce the quantity of fuse 3 in the unit are, reduces capacitor and in use generates heat; Increase its useful life; Part metals coating module 1 comprises number of metal coating unit 111, breaks off through gap 2 between the adjacent metal coating unit 111, is electrically connected through fuse 3 between the adjacent metal coating unit 111; Coat of metal module 11 next-door neighbours that comprise coat of metal unit 111 do not comprise the coat of metal module 12 of coat of metal unit 111; Owing to comprise the existence of the coat of metal module 1 of coat of metal unit 111,, coat of metal unit 111 is isolated through blow out fuse 3 when capacitor transships locally when breakdown; At this moment; The area of isolating is less with respect to coat of metal module 11 areas, and loss effectively less than normal over against area makes the utility model after experiencing repeatedly self-healing process, still keep good performance.
The utility model is not limited thereto execution mode, and the related realization assembly that is the basis with the utility model thought is all in the protection range of the utility model.
Claims (2)
1. one kind is hanged down the metallized film that generates heat and have multiple protection functions; Be used for the manufacturing of capacitor, comprise the coat of metal and the carrier that adheres to the said coat of metal, the said coat of metal comprises number of metal coating module; Break off through the gap between the adjacent said coat of metal module; It is characterized in that be electrically connected through fuse between the adjacent said coat of metal module of part, the said coat of metal module of part comprises number of metal coating unit; Break off through the gap between the adjacent said coat of metal unit, be electrically connected through fuse between the adjacent said coat of metal unit.
