Abstract
The utility model relates to a metallizing thin-film explosive-proof capacitor, which solves the problem that the utility model provides a novel metallizing thin-film explosive-proof capacitor which has high explosive-proof reliability and can reduce manufacturing cost, by improving the metallizing thin-film explosive-proof capacitor. The utility model is characterized in that the lower end surface of a conductive column is an arc surface which extends to the outside of an explosive-proof plate and is connected with a copper foil sheet, and the other surface of the copper foil sheet is connected with a copper core. The utility model has the advantages that when the product loses the effect, the welding point between the copper foil and the conductive column is broken, so that a core body is disengaged from a power source to play the protective action. The arc surface at the lower end of the conductive column raises the strength of the spot welding point with the copper foil, which are hard to shed. The electrical connection performance is favorable, the loss of the product can be reduced, and meanwhile, manufacturing cost is reduced.
Description
Technical field
The utility model relates to the metallized film noinductive capacitor.
Background technology
Metallic film capacitor all can decompose generation gas after losing efficacy, and simultaneously with high temperature, very easily set off an explosion and combustion phenomena.For avoiding occurring above-mentioned phenomenon, such capacitor is provided with safety protection structure, its principle is the gas that produces after utilizing capacitor to lose efficacy, after internal pressure increased, cap produced and is out of shape, and made the explosion-proof utmost point of fixed range form the distance increase in cap distortion back, thereby the explosion-proof utmost point is broken, capacitor core body deenergization, what prevent from effectively to destroy further spreads, and plays the security protection effect.
Now the safety protection structure of Cai Yonging all adopts the mode of soldering, the explosion-proof utmost point one end soldering is on conductive pole, and other end soldering is this infrastructure product technological process complexity on the iron plate of bursting diaphragm, and it is bigger that the quality of product processing is influenced by human factor, quality conformance is poor, causes explosion-proof reliability poor.
Summary of the invention
The purpose of this utility model is: by the improvement to existing metallized film noinductive capacitor structure, provide the novel metal film noinductive capacitor of a kind of explosion-proof reliability height, reduction manufacturing cost.
The art designs scheme that realizes the foregoing invention purpose is as follows:
1, novel metal film noinductive capacitor comprises two binding posts, two insulators, iron covering, two conductive poles, insulating board, bursting diaphragm, copper core, fuse and shells, it is characterized in that:
The lower surface of described conductive pole is an arc surface, and extends bursting diaphragm and connecting copper foil outward, and the another side of copper foil is connecting copper core.
2, according to above-mentioned 1 described novel metal film noinductive capacitor, it is characterized in that: fixedly connected for spot welding between the lower end arc surface of described conductive pole and the copper foil, fixedly connected for spot welding between copper foil and the copper core.
Useful technique effect of the present utility model is: the Copper Foil direct spot welding fixedly connected conductive pole, behind product failure, the pad between Copper Foil and the conductive pole will disconnect, and core body and power supply are broken away from, and plays a protective role.The lower surface of conductive pole is an arcwall face, has improved the intensity with Copper Foil spot welding place, difficult drop-off, and electrical connection properties is good, has reduced the loss of product, has also improved security of products energy and explosion-proof reliability simultaneously.Simultaneously, because of not needing to use soft fine wlding material and explosion-proof utmost point material, reduced production cost.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Referring to Fig. 1, novel metal film noinductive capacitor comprises two binding posts 1, two insulators 2, iron covering 3, two conductive poles 4, insulating board 5, bursting diaphragm 6, copper core 7, fuse and shells.
