Description
Technical field
This utility model relates to a kind of capacitor.
Background technology
It is little that metallic film capacitor has volume, the advantage that capacity is big, but capacity easily occurs in long-term work condition
Lose and after spontaneous recovery, all may result in capacity and reduce；Simultaneously as metallization film capacitor than metal forming thin a lot, carrying is big
Current capacity is more weak.It is thus desirable to shortcoming at above two is improved.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, it is provided that one length in service life, safe and reliable, structure
Simple a kind of capacitor.
The purpose of this utility model is achieved through the following technical solutions: a kind of capacitor, including shell, shell lower end is provided with and adds
Qiang Guan, is provided with core body inside shell, core body is sequentially provided with metallized film layers, metal foil layer from the inside to surface, metallized film layers by
The metal level of surface spraying after polypropylene film and polyester film and polypropylene film bond with polyester film is constituted, metal
Change thin layer and metal foil layer trypsin method has alloy-layer, alloy-layer both sides to be provided with pin, be filled with between core body and pin and shell
Insulating paper, is packaged with resin at shell opener.
Further improvement of the utility model is: at shell opener, the resin of encapsulation is flame retardant epoxy type.
This utility model compared with prior art has the advantage that
Shell lower end is provided with the local frangibility that reinforced pipe, pin and resin intersect, and the setting of reinforced pipe serves protection and draws
The effect of foot；Metallized film layers has electrical characteristic, high stability and the long-life of excellence；Metallized film layers is by polypropylene
The metal level of surface spraying after film layer and polyester film and polypropylene film bond with polyester film is constituted, polypropylene film
Have loss little, insulation resistance is high, frequency characteristic good and is amenable to the characteristic such as high voltage, heavy current impact, polyester film has
The characteristic that operating temperature range is wide, insulation resistance is high, volume is little, volumetric ratio is high, polyester film and polypropylene film and polyester
The metal level of the surface spraying after the bonding of film layer is the most oxidizable, and service life is long, and electric conductivity, self-healing property, adhesive force are the most simultaneously
By force；Metallized film layers and the combination of conventional metals layers of foil, extend the service life that capacitor is overall；Core body and pin and shell
Between be filled with insulating paper, insulating paper has not only acted as the effect of insulation, may also operate as buffering, firm effect simultaneously, protects
Protect pin, extend the service life of pin, and add thermal diffusivity.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model；
Label in figure: 1-shell, 2-reinforced pipe, 3-resin, 4-metallized film layers, 5-metal foil layer, 6-polypropylene film,
7-polyester film, 8-metal level, 9-alloy-layer, 10-pin, 11-insulating paper.
Detailed description of the invention:
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, this utility model is made further
Describing in detail, this embodiment is only used for explaining this utility model, is not intended that the restriction to this utility model protection domain.
As Fig. 1 shows a kind of embodiment of a kind of capacitor of this utility model, a kind of capacitor, including shell 1, shell 1
Lower end is provided with reinforced pipe 2, and shell 1 is internal is provided with core body, and core body is sequentially provided with metallized film layers 4, metal foil layer 5 from the inside to surface,
Metallized film layers 4 is bonded rear surface spraying with polyester film 7 and polypropylene film 6 with polyester film 7 by polypropylene film 6
Metal level 8 constitute, metallized film layers 4 and metal foil layer 5 trypsin method have alloy-layer 9, alloy-layer 9 both sides to be provided with pin 10,
Being filled with insulating paper 11 between core body and pin 10 and shell 1, shell 1 opening part is packaged with resin 3, and resin 3 is flame retardant epoxy type.
The foregoing is only explanation embodiment of the present utility model, be not limited to this utility model, for ability
For the technical staff in territory, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement made
Deng, within should be included in protection domain of the present utility model.
