The utility model discloses a metallized film for a capacitor, which belongs to the field of capacitors. The metallized film for the capacitor includes the screen belt and the metal coating arranged on the upper layer of the screen belt; the metal coating includes the thickening area of the edge of the safety film and the non thickening area of the safety film; the edge of one end of the screen belt is a wavy structure; the problem of the weak capacity of the capacitor to bear the maximum peak current, the maximum impact current and the ripple current is solved; the maximum peak current of the capacitor is increased The bearing capacity of the maximum impact current and ripple current capacity. There are multiple inverted V-shaped transparent strips and multiple Y-shaped transparent strips on the non thickened area of the safety film. The inverted V-shaped transparent strip, Y-shaped transparent strip and screen belt separate the non thickened area of the safety film into several cells that make up the capacitor. The metal coating between the inverted V-shaped transparent strip and the adjacent edge of the Y-shaped transparent strip is connected to play the role of insurance The capacitor is in the open circuit state when it fails, which has no effect on other surrounding circuits.
【技术实现步骤摘要】
一种用于电容器的金属化膜
本技术实施例涉及电容器领域,特别涉及一种用于电容器的金属化膜。
技术介绍
普通金属化膜电容器的边缘加厚区窄,甚至有些没有边缘加厚区,导致电容器承受最大峰值电流、最大冲击电流和波纹电流的能力较弱。当电容器两极间的电压超过普通金属化膜的承受范围时,电容器会击穿,击穿方式不确定,可能呈现短路状态也可能呈现开路状态,如果电容器击穿呈现短路状态,会对周围其他电路造成不良影响。
技术实现思路
为了解决现有技术的问题,本技术实施例提供了一种用于电容器的金属化膜。该技术方案如下:第一方面,提供了一种用于电容器的金属化膜,包括屏带、设置在屏带上层的金属镀层;金属镀层包括安全膜边缘加厚区和安全膜非加厚区;屏带的一端的边缘为波浪形结构;在安全膜非加厚区上,设置有多个倒V型透明条和多个Y型透明条,倒V型透明条、Y型透明条与屏带将安全膜非加厚区分隔为若干个组成电容器的单元格,倒V型透明条与Y型透明条相邻的边之间设置有间隙,倒V型透明条的顶端与安全膜边缘加厚区接触;其中, ...
