Bottom, the exit are connect by rivet with insulating bowl and cover board, and the copper foil connector passes through the corresponding card of insertion explosion-proof block
It is mouthful fixed, make it be integrally connected to form capacitor end cap, the capacitor end cap by the welding lead on copper foil connector, with
Lead is that medium is connected with capacitor element；
The pink cylindrical sleeve that the lower insulation system is integrally formed, the cylindrical sleeve are capacity cell core
The insulating protection of body and lower end surface.
The cover board is equipped with oil filler point as a further improvement of the utility model,.
The extending column of reinforcing is prevented as a further improvement of the utility model, for the insulation of capacitor element upper surface
Shield, the reinforcement extending column height are 5mm.
Compared with the prior art the utility model has the advantage that
1, the upper insulation system of the insulation system be capacitor end cap explosion-proof block on reinforcement extending column, height 5mm,
5000V DC break down voltage (1500V ac voltage withstanding) can be born, the pressure resistance compared with existing conventional capacitance explosion-proof block improves 150%, makes
The security performance for obtaining capacitor is substantially improved.
2, the upper insulation of the insulation system be capacitor end cap explosion-proof block on reinforcement extending column, used this kind it is novel absolutely
It after edge structure, eliminates capacity cell and puts on positioning sleeve this operation, that is, reduce during capacitor production operation together
Master operation substantially increases production efficiency, reduces the cost of labor of polypropylene film capacitor production.
3, the lower insulating structure design of the insulation system be cylindrical sleeve, can simultaneously protection capacitance element lower end surface and core
Body.Its unique cylinder design is time-consuming and laborious when solving original insulation system actual production assembling and can not keep up with flowing water
The shortcomings that speed of line, need to only be put into corresponding cylindrical sleeve, operation letter in capacitor actual production into aluminum hull
It is single, quick, it can be operated with line, without setting up one of preparatory process, substantially increase the production efficiency of polypropylene film capacitor,
Reduce the production cost of polypropylene film capacitor.
4, the lower insulative cylinders shape sleeve of the insulation system is integrally formed, solve original insulation system polyester film and
Accidentally bending when lower positioning sleeve may be due to polyester membrane operations when being applied in combination and there are gaps, truly realize
The comprehensive no dead angle of element core and lower end surface is protected, more securely and reliably.In addition, also justifying just because of the lower insulation
The unique integrated formed structure of cylindrical sleeve, in element assembling, it is more convenient that element is operated into shell, will not generate capacitor again
When element is assembled into shell upper positioning sleeve blocked by polyester film and can not be into shell the phenomenon that, capacitor production efficiency is substantially improved.
5, the lower insulative cylinders shape sleeve design of the insulation system is pink, solves original insulating blanked clamper film due to nothing
Color it is transparent and in assembling there are visual blind spot, leakage is not easy to be found after putting, and causes to capacitor safe performance very big
Hidden danger.Therefore, it is designed to pink and can prevent in existing production leakage to put capacitor safe performance caused by insulating blanked clamper film
Hidden danger, more securely and reliably, it helps employee's actual production group loads fool proof when insulation.

Specific embodiment
The utility model will be further described in conjunction with the embodiment in attached drawing below:
As Figure 1-Figure 4, a kind of integrated insulation system for polypropylene film capacitor is tied by upper insulation
The integration insulation knot that structure and lower insulation system composition, the upper insulation system and lower insulation system pass through assembling as capacitor
Structure.
The upper insulation system includes cover board 1, explosion-proof block 2, copper foil connector 3, rivet 4, reinforces extending column 5, oil filler point
6, insulating bowl 7 and exit 8.By being stamped and formed out oil filler point 6 on cover board 1, reinforce prolonging by being moulded on explosion-proof block 2 to be formed
Column 5 is stretched, then by being stamped and formed out exit 8 and rivet 4, wherein rivet 4 passes through bottom in the bottom of exit 8, exit 8
It is installed on cover board 1 again after the centre bore that rivet 4 passes through insulating bowl 7 and corresponds to punching hole, copper foil connector 3 passes through insertion explosion-proof block
2 corresponding bayonets are fixed, and by rivet 4 come fixed terminal 8, insulating bowl 7, cover board 1, explosion-proof block 2, copper foil connector 3, make its company
Being connected in one is capacitor end cap.Capacitor end cap is by the welding lead on copper foil connector 3, using lead as medium and electricity
Container component is connected.
The pink cylindrical sleeve 9 that the lower insulation system is integrally formed, the cylindrical sleeve 9 are capacity cell
The insulating protection of core and lower end surface, so that capacitor internal insulation is more easily assembled, is more safe and reliable, it is practical raw in capacitor
Corresponding cylindrical sleeve need to be only put into when production into aluminum hull.
Insulating protection of the reinforcement extending column 5 of the upper insulation system for capacitor element upper surface, height 5mm,
It can bear 5000V DC break down voltage (1500V ac voltage withstanding).The insulation pressure resistance of capacitor end cap improved 150% compared with originally, made
The security performance for obtaining capacitor is substantially improved.After this kind of New Insulation Structure, eliminate capacity cell put on positioning sleeve this
One operation, that is, reduce one during capacitor production operation of master operation, substantially increase production efficiency, reduce poly-
The cost of labor of Polypropylene film capacitor production.
The pink cylindrical sleeve 9 that the lower insulating Design of insulation system is integrally formed, unique cylinder design
Can simultaneously protective capacitor element lower end surface and core.And the insulation system need to only be put in capacitor actual production into aluminum hull
Enter corresponding cylindrical sleeve, it is easy to operate, quick, it can be operated with line, so that the production efficiency of polypropylene film capacitor
It greatly promotes, cost of labor has also obtained apparent reduction.
Meanwhile the lower insulative cylinders shape sleeve of the insulation system is integrally formed, compared to the polyester of original insulation system
When film and lower positioning sleeve are applied in combination, it may be realized pair due to polyester film accidentally bending when assembled and there are gap
The comprehensive no dead angle protection of element core and lower end surface, more securely and reliably.In addition, also just because of the lower insulative cylinders shape
The unique integrated formed structure of sleeve, in element assembling, it is more convenient that element is operated into shell, will not generate capacitor element again
When being assembled into shell upper positioning sleeve blocked by polyester film and can not be into shell the phenomenon that, capacitor production efficiency is substantially improved.
It is not only easy to operate using pink cylindrical sleeve, and its pink design has prevented leakage in original production and has put nothing
Color transparent insulation presss from both sides the hidden danger of capacitor safe performance caused by film, more securely and reliably, it helps employee's actual production group
Load fool proof when insulation.
A kind of integrated insulation system for polypropylene film capacitor of the utility model, using reinforce extending column 5 as
The insulating protection of capacity cell upper surface, insulation is cylindrical sleeve 9 as the exhausted of capacitor element core and lower end surface below
Edge protection can be used as capacitor insulation structure by assembling.
