Abstract
The utility model relates to a kind of metalized film that can bearing great current, comprise: metal area and non-metallic areas, described non-metallic areas comprises: the first isolation strip and the second isolation strip, and mutually vertical, the first isolation strip and the second isolation strip are divided into four the first adjacent metal areas, the second metal area, the 3rd metal area, the 4th metal area by metal area, face the overlapping edges place connecing arrange and prevent excessive and easy breakdown arc transition district or the straight transitions district of electric current in each metal area and non-metallic areas.Metalized film described in the utility model, adopts arc transition district or straight transitions district to replace original sharp-pointed salient point, and the overlapping edges place that allows metal area and non-metallic areas face to connect is not collecting electric current, thereby can carry larger electric current.In the constant situation of other conditions, the ampacity of this metalized film can increase more than 1 times, has avoided the inefficacy of capacitor, meets actual operation requirements, and implementation result is good.
Description
Technical field
The utility model relates to a kind of capacitor metalized film, relates in particular to a kind of metalized film that can bearing great current, belongs to technical field of electronic components.
Background technology
In the past few years, along with information industry and hyundai electronics equipment, instrument and meter are towards future developments such as miniaturization, lightweight, low cost, high-performance, distinguishing features such as metallic film capacitor is large with its withstand voltage span, wide coverage, self-healing performance is good, adaptation field is wide and obtained paying attention to widely and applying.Metallic film capacitor is as base electronic components and parts, the demand in market increases year by year, and its model, specification, kind get more and more, and constantly widen in the field of use, the technical grade of product, the technology in manufacture and the technology content of production equipment are also constantly improving.
Along with electronic technology is constantly to high-grade, precision and advanced future development, more and more higher to the technology controlling and process of capacitor and quality requirement.Metallized film is to consist of the metal that on plastic film, vacuum evaporation last layer is very thin, and this layer of metal is used as electrode.On existing common metal film, isolating bar is set, prevents in metalized film self-healing process that putting neighbouring multilayer dielectricity with self-healing burns and puncture, and causes capacitor short-circuit to lose efficacy.But in fact, arranging of isolating bar increased electric current in the collecting of part sometimes simultaneously, cause the electric current that collects excessive and uncontrollable, finally increased on the contrary probability that metalized film is burnt and punctured, impact is actual to be used.
Utility model content
The deficiency that the utility model exists for prior art just, provides a kind of metalized film that can bearing great current.
For addressing the above problem, technical solution adopted in the utility model is as follows:
A kind of metalized film that can bearing great current, comprise: metal area and non-metallic areas, described non-metallic areas comprises: the first isolation strip and the second isolation strip, and mutually vertical, the first isolation strip and the second isolation strip are divided into four the first adjacent metal areas, the second metal area, the 3rd metal area, the 4th metal area by metal area, face the overlapping edges place connecing arrange and prevent excessive and easy breakdown arc transition district or the straight transitions district of electric current in each metal area and non-metallic areas.
Compared with prior art, implementation result of the present utility model is as follows for the utility model:
Metalized film described in the utility model, adopts arc transition district or straight transitions district to replace original sharp-pointed salient point, and the overlapping edges place that allows metal area and non-metallic areas face to connect no longer collects electric current, thereby can carry larger electric current.In the constant situation of other conditions, the ampacity of this metalized film can increase more than 1 times, has avoided the inefficacy of capacitor, meets actual operation requirements, and implementation result is good.

Fig. 2 is metallized film structure schematic diagram described in the utility model (embodiment mono-);
Fig. 3 is metallized film structure schematic diagram described in the utility model (embodiment bis-).
Embodiment
Content of the present utility model is described below in conjunction with specific embodiments.
As shown in Figure 1, be metallized film structure schematic diagram in prior art, described metalized film comprises: basement membrane and metal steam plated film, metal steam plated film is only arranged on the surface of basement membrane one side.Described metalized film comprises: 10Ji non-metallic areas, metal area 20, metal area 10 is for adopting evaporation process to form metal steam plated film on basement membrane, evaporation region formation non-metallic areas 20 not on basement membrane.
As shown in Figure 1, described non-metallic areas 20 comprises: the first isolation strip 21 and the second isolation strip 22, and mutually vertical, the first isolation strip 21 and the second 22Jiang metal area, isolation strip 10 are divided into four adjacent the first metal area 11, the second metal area 12, the 3rd metal area 13, the 4th metal areas 14.10Yu non-metallic areas, metal area 20 is faced the crosspoint connecing and is formed sharp-pointed salient point 30.
When metalized film rolls formation capacitor plug, metal area 10 is using the electrode as capacitor.Due to the existence of non-metallic areas 20, electric current by the A along in Fig. 1 to or B to flowing, due to the existence of sharp-pointed salient point 30, current density is herein maximum, caloric value is also maximum, metalized film is also the most breakdown.
As shown in Figure 2, be metallized film structure schematic diagram described in the utility model embodiment mono-.Metalized film described in the utility model, faces in each 10Yu non-metallic areas, metal area 20 the overlapping edges place connecing arc transition district 15 is set, and by arc transition district 15, replaces original sharp-pointed salient point 30.Like this, when electric current along the A in figure to or B when mobile, electric current is herein shunted, and cannot form current concentrated district, its current density is even, caloric value is lower, metalized film is not easy breakdown herein.
As shown in Figure 3, be metallized film structure schematic diagram described in the utility model embodiment bis-.Metalized film described in the utility model, faces in each 10Yu non-metallic areas, metal area 20 the overlapping edges place connecing straight transitions district 16 is set, and by straight transitions district 16, replaces original sharp-pointed salient point 30.Like this, when electric current along the A in figure to or B when mobile, electric current is herein shunted, and cannot form current concentrated district, its current density is even, caloric value is lower, metalized film is not easy breakdown herein.
