Abstract
The utility model provides a metalized film with multiple protection functions, which is used for manufacture of capacitors. The metalized film comprises a metal coating and a carrier adhere to the metal coating, wherein the metal coating comprises a plurality of metal coating modules. The adjacent metal coating modules are disconnected through gaps and are electrically connected through fuse wires. The metal coating modules comprise a plurality metal coating units, the metal coating units are disconnected through the gaps, and the adjacent metal coating units are electrically connected through the fuse wires. The metalized film with multiple protection functions can realize the purpose that the metalized film after multiple self-healing still can keep a good performance.
Description
Technical field
The utility model relates to a kind of metallized film with 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.When capacitor occurred puncturing through current overload, fuse c was vaporized under the effect of instantaneous large-current, made 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 occur to puncture, 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 that when capacitor was 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 metallized film with multiple protection functions, 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 metallized film with 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, said coat of metal module comprises number of metal coating unit; Break off through the gap between the said coat of metal unit, be electrically connected through fuse between the adjacent said coat of metal unit.
Based on disclosing of above technical scheme, the utlity model has following beneficial effect:
When capacitor transships local when breakdown; Through blow out fuse coat of metal unit is isolated; 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.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explanation:
Fig. 1 is the structure diagram of a kind of metallized film in the prior art;
Among the figure:
A, coat of metal unit; B, gap; C, fuse;
Fig. 2 is the structure diagram of a kind of metallized film among the utility model embodiment 1;
Among the figure:
1, coat of metal module; 11, coat of metal unit; 2, gap; 3, fuse.
Embodiment
Following embodiment 1 and Fig. 2 of combining is described further the utility model:
The utility model proposes a kind of metallized film with 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 adjacent metal coating module 1; Coat of metal module 1 comprises number of metal coating unit 11; Break off through gap 2 between the coat of metal unit 11, be electrically connected through fuse 3 between the adjacent metal coating unit 11, the utility model is through being decomposed into coat of metal module 1 number of metal coating unit 11; When capacitor transships local when breakdown; Through blow out fuse 3 coat of metal unit 11 is isolated, at this moment, the area of isolation is less with respect to coat of metal module 1 area; That loses is 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.
