Abstract
The utility model discloses a capacitor-used plate-type internal fuse comprising an internal fuse body; two ends of the internal fuse body are ineffective portions, and the middle portion of the internal fuse body is effective portion in a plate shape. The internal fuse body is in a shape of an L; the ineffective portions are in a plate shape; an L-shaped bending point of the internal fuse body is positioned on the ineffective portion; the internal fuse body employs electrotinning alloy. The capacitor-used plate-type internal fuse uses small space, is good in heat radiation effect, and can effectively and fast melt when elements are breakthrough under low-voltage, thereby protecting the capacitor.
Description
Technical field
The utility model belongs to capacitor protection device technical field, is specifically related to fuse in chip for a kind of capacitor.
Background technology
In capacitor, fuse is a kind of device for capacitor for voltage protection; while having indivedual bad elements to puncture in capacitor; the interior fuse of connecting with this element will quick-break, thereby will puncture element excision, makes whole the capacitor still can be at electrical network relaying reforwarding row.Yet fuse is commonly fuse in column type in existing capacitor, exists following problem: thickness is large, cause that to take capacitor space large; Surface area is little, causes the anti-skin effect of product poor, unfavorable heat radiation; Fusing lower voltage limit high, while causing element to puncture under low-voltage in fuse do not fuse, cannot play a protective role.
Utility model content
The purpose of this utility model is to provide fuse in chip for a kind of capacitor, has solved that fuse space hold in existing column type capacitor is large, the little unfavorable heat radiation of surface area and the problem of capacitor for voltage protection can not play component breakdown under low-voltage time.
The technical scheme that the utility model adopts is: fuse in chip for capacitor, comprise interior fuse, and the two ends of interior fuse are invalid part, and centre is live part, and live part is sheet.Interior fuse is " L " type.Invalid part is sheet." L " type flex point of interior fuse is positioned at invalid part place.Interior fuse adopts electrotinning alloy.
The beneficial effects of the utility model are: the utility model capacitor takes up room little with fuse in chip, and perfect heat-dissipating during component breakdown, can effectively fuse rapidly under low-voltage, and capacitor is protected.
Accompanying drawing explanation
Fig. 1 is the structural representation of fuse in chip for the utility model capacitor.
In figure, 1. interior fuse, 2. invalid part, 3. live part.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The utility model provides fuse in chip for a kind of capacitor, comprises interior fuse 1, and the two ends of interior fuse 1 are invalid part 2, and centre is live part 3, and live part 3 is sheet.Interior fuse 1 is " L " type.Invalid part 2 is sheet." L " type flex point of interior fuse 1 is positioned at invalid part 2 places.Interior fuse 1 adopts electrotinning alloy.
Interior fuse 1 of the present utility model is " L " type, is convenient to welded and installed.The invalid part 2 of interior fuse 1 and live part 3 be shaped as sheet, one has reduced to take capacitor space because thickness is little; Two come aspect surface area to increase, and are about 2.5 times of the interior fuse surface area of existing column type capacitor, according to skin effect, are conducive to heat radiation; Three come laminated structure than the easy fusing of cylindrical-shaped structure, are beneficial to the protection effect of interior fuse.And the electrotinning alloy that interior fuse 1 adopts is led good fluidity, thereby also impel interior fuse to be more prone to fusing.
During use, by interior fuse 1, use bonding method is hidden is fixed on subassembly wrapper, and directly connects with element, and invalid part 2 90-degree bents weld.During work, when element moves under high voltage, not malfunction of the utility model.When element moves under low-voltage, and element is when break down, live part 3 quick-breaks of the present utility model.Thereby reach the interior fuse of capacitor in not malfunction of high voltage, the stable superperformance of not tripping of low-voltage.
The utility model is simple in structure, functional, successful.
Claims (1)
1. fuse in chip for capacitor, it is characterized in that: comprise interior fuse (1), the two ends of described interior fuse (1) are invalid part (2), centre is live part (3), described live part (3) is sheet, and described interior fuse (1) is " L " type, and described invalid part (2) is sheet, " L " type flex point of described interior fuse (1) is positioned at described invalid part (2) to be located, and described interior fuse (1) adopts electrotinning alloy.
