The technical solution adopted in the present invention is: safe low-cost type capacitor, housing including upper opening, this housing upper opening part is provided with metal cover board, this metal cover board is provided with the metal terminal of this hull outside, explosion-proof block and the copper sheet of electrical connection respective metal terminal it is fixed with below this metal cover board, simultaneously, positioning sleeve and fuse it is provided with in this housing, this positioning sleeve is for positioning this fuse and the connecting line of location this fuse of electrical connection and corresponding copper sheet, and, this fuse and positioning sleeve adopt PP material to prepare, this housing adopts aluminum shell, it is filled with inserts in this housing, described outside core is provided with PET peplos.
Described inserts is dry insulating air or six-component force balance gas.
Described metal terminal lower surface has the metal ferrule downwardly extended, the cross-sectional area of metal ferrule is less than the cross-sectional area of respective metal terminal, and metal terminal and its corresponding metal ferrule be provided externally with injection molded layers, simultaneously, metal ferrule sequentially passes through downwards this metal cover board and this explosion-proof block, and, copper sheet is welded on the bottom of corresponding metal ferrule by the mode welded, and copper sheet and corresponding metal ferrule electrically connect.
The preparation method of safe low-cost type capacitor, the housing including routine prepares, prepares fuse, arranges peplos for fuse, load positioning sleeve and fuse, seal casinghousing, insert the step of inserts, described peplos is set for fuse mode be: first PET peplos one side precoat PUR, then this PET peplos is wound around 8～20 circles at outside core, afterwards, toast under the constant temperature of any one temperature spot in 100～110 DEG C, until peplos is wrapped in the outside of fuse closely.
Advantage for present invention is:
1, structure is relatively stable, it is safer to use. The fuse of the safe low-cost type capacitor of the present invention is same as prior art many employings PP material to be prepared, and the peplos of outside core adopts PET material to prepare, due to PP material there is negative temperature characteristic, PET material has positive temperature characterisitic, so that the structure of this capacitor tends towards stability. Meanwhile, inserts adopts dry air or six-component force balance gas, not only reduces the weight of product, reduces product cost, and inserts is nontoxic, will not burn, and adds safety when capacitor uses.
2, assembling is simple, less costly, and better quality. The metal explosion-proof lid material therefor parts of the safe low-cost type capacitor of the present invention are less, not only reduce material cost, and only need once to weld, greatly simplify assembly technology. Meanwhile, the minimizing of assembly process and the minimizing of material components, all make the quality of product obtain certain guarantee.

Detailed description of the invention
Embodiment, as shown in Figure 1: safe low-cost type capacitor, including the housing 10 of upper opening. This housing 10 upper opening place is provided with metal cover board 20, and this metal cover board 20 is provided with this metal terminal 30 outside housing 10, is fixed with explosion-proof block 21 and the copper sheet 22 of electrical connection respective metal terminal 30 below this metal cover board 20. Obviously, metal terminal 30, copper sheet 22 are 2, and metal terminal 30, copper sheet 22 are corresponding between two. Meanwhile, it is provided with positioning sleeve 40 and fuse 50 in this housing 10. This positioning sleeve 40 is for positioning this fuse 50 and the connecting line of location this fuse 50 of electrical connection and corresponding copper sheet 22. And, this fuse 50 and positioning sleeve 40 adopt PP material to prepare, and this housing 10 adopts aluminum shell, are filled with inserts 60 in this housing 10.
Further saying, this fuse 50 is provided externally with PET peplos. So, due to PP material there is negative temperature characteristic, PET material has positive temperature characterisitic, so that the structure of this capacitor tends towards stability.
Continue to optimize:
This inserts 60 is dry insulating air or six-component force balance gas. Wherein, especially six-component force balance gas not only nontoxic, do not burn, have more excellence insulation and arc extinction performance, improve the safety of product.
Shown in Fig. 2, metal terminal 30 lower surface has the metal ferrule 31 downwardly extended. Metal ferrule 31 can be a part for respective metal terminal 30. The cross-sectional area of metal ferrule 31 is less than the cross-sectional area of respective metal terminal 30. Such as, when metal terminal 30 and metal ferrule 31 are cylinder, the diameter of metal ferrule 31 is less than the diameter of respective metal terminal 30. Metal terminal 30 and respective metal contact pin 31 be provided externally with injection molded layers (not shown on figure). Simultaneously, after metal ferrule 31 sequentially passes through downwards this metal cover board 20 and the explosion-proof block 21 corresponding with this metal terminal 30, corresponding copper sheet 22 is welded on the bottom of metal ferrule 31 by the mode welded, and copper sheet 22 and corresponding metal ferrule 31 electrically connect. Such as, by the mode cut, make the bottom of metal ferrule 31 expose, afterwards, copper sheet 22 is welded on corresponding metal ferrule 31. Obviously, metal terminal 30 is positioned at the top of this metal cover board 20. So, by reducing required parts, the metal explosion-proof lid making this safe low-cost type capacitor is less costly, be easily assembled, and quality is relatively stable.
The preparation method of previous security low-cost type capacitor, the housing including routine prepares, prepares fuse, arranges peplos for fuse, load positioning sleeve and fuse, seal casinghousing, insert the step of inserts. Institute the difference is that, the mode arranging peplos for fuse is: first PET peplos one side precoat PUR, then by this PET peplos outside core be wound around 8～20 circle. Such as, 8 circles, 12 circles or 20 circles it are wound around. Certainly, there is the one side of PUR inwardly. Afterwards, toast under the constant temperature of any one temperature spot in 100～110 DEG C, until peplos is wrapped in the outside of fuse closely. Baking process can carry out in constant temperature roaster, and set temperature can be 100 DEG C, 105 DEG C or 110 DEG C. So, these peploses define the surrounding layer of fuse, are conducive to improving the stability of capacitor.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the present invention and accompanying drawing content to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, all in like manner include in the scope of patent protection of the present invention.
