Embodiment
For the ease of understanding the utility model, below with reference to relevant drawings, the utility model is described more fully.Preferred embodiment of the present utility model is given in accompanying drawing.But the utility model can realize in many different forms, is not limited to embodiment described herein.On the contrary, provide the object of these embodiments be make the understanding of disclosure of the present utility model more comprehensively thorough.
Unless otherwise defined, all technology used herein and scientific terminology are identical with belonging to the implication that those skilled in the art of the present utility model understand usually.The object of the term used in specification of the present utility model herein just in order to describe specific embodiment, is not intended to limit the utility model.Term as used herein "and/or" comprises arbitrary and all combinations of one or more relevant Listed Items.
Traditional electrochemical capacitor packaging technology, when assembling sealing, shape with a tight waist is arc groove.Due to stopper thinner thickness, when mould with a tight waist is formed with a tight waist on shell, easily occur mutually to slide between the with a tight waist and stopper (micelle) of arc, thus there will be position with a tight waist not on stopper or position with a tight waist be seriously displaced to bottom or the top of stopper, so that sealing difference does not even have the effect of sealing, directly cause electrochemical capacitor electrolyte inside seepage or occur the phenomenons such as the electrochemical capacitor drum end, impact is greatly existed on the life-span of electrochemical capacitor.And even if position with a tight waist is on stopper, owing to girdling the waist as arc groove, the contact area of groove bottom land and stopper is limited, also there is the defect of sealing difference.Therefore, be necessary to provide good electrolytic capacitor of a kind of sealing and preparation method thereof.
A kind of electrolytic capacitor, comprises fuse, stopper and shell.Shell collecting fuse and stopper, shell is provided with girdling the waist around stopper, the groove of girdling the waist as rectangle or trapezoid cross section, girdles the waist and is close to or is absorbed in stopper side.
Above-mentioned electrolytic capacitor, adopt rectangle or the with a tight waist of trapezoidal groove cross section to seal, increase contact area that is with a tight waist and stopper, make the sealing of electrolytic capacitor improve further, reduce the possibility of solution leakage, improve the useful life of electrolytic capacitor.
Above-mentioned electrolytic capacitor, rectangle or the with a tight waist of trapezoidal groove cross section is adopted to seal, neither appear between with a tight waist when being formed with a tight waist and stopper (micelle) and easily mutual sliding phenomenon occurs, again because bottom land exists one compared with large contact surface and increases contact area that is with a tight waist and stopper, the sealing of electrolytic capacitor is made to improve further, reduce the possibility of solution leakage, improve the useful life of electrolytic capacitor.
Fig. 1 is the electrolytic capacitor schematic diagram of an embodiment.
A kind of electrolytic capacitor, comprises fuse 100, positive pole pin 110, negative pole pin 120, stopper 200 and shell 300.Fuse 100, stopper 200 and shell 300 profile are all cylindric.Fuse 100 is the roll film shape layered product of dipped electrolyte, and comprise cathode foil, anode foil and electrolytic paper, positive pole pin 110 is connected fuse 100 with negative pole pin 120.Stopper 200 is soft material, such as rubber.Shell 300 is aluminium matter or aluminum alloy casing.
Stopper 200 is arranged on fuse 100 through positive pole pin 110 and negative pole pin 120.Shell 300 accommodates fuse 100 and stopper 200, and shell 300 is provided with around stopper 200 with a tight waist 310, and with a tight waist 310 be the groove of rectangle or trapezoid cross section, girdles the waist 310 be close to or be absorbed in stopper 200 side.
In the present embodiment, the slot bottom width d of 310 rectangles formed with a tight waist or trapezoidal groove is 0.4 ~ 0.6 times of stopper 200 width D, is preferably 0.5 times.With a tight waist 310 around the centre position of stopper 200.
With a tight waist 310 of rectangle or trapezoidal groove are adopted to seal, neither appear in and with a tight waistly when being formed with a tight waist between 310 and stopper 200, easily mutual sliding phenomenon occurs, again because the bottom land of with a tight waist 200 exists one compared with large contact surface and increases the contact area of with a tight waist 200 and stopper 310, the sealing of electrolytic capacitor is made to be improved, reduce the possibility of solution leakage, improve the useful life of electrolytic capacitor.
Be filled with sealant (not shown) between stopper 200 and with a tight waist 310, sealant can be polyvinyl alcohol (PVA, polyvinyl alcohol) or anaerobic adhesive.The existence of sealant, makes the better tightness between stopper 200 and with a tight waist 310, thus avoids solution leakage.
The invention also discloses the manufacture method of above-mentioned electrolytic capacitor.
Fig. 2 is the manufacture method flow chart of the electrolytic capacitor of an embodiment.
A manufacture method for electrolytic capacitor, comprises step:
Step S100: fuse 100, stopper 200 and shell 300 are provided.Fuse dish, stopper dish and shell dish provide fuse 100, stopper 200 and shell 300 respectively.
Step S200: stopper 200 is arranged on fuse 100.Stopper 200 is enclosed within fuse 100 through positive pole pin 110 and negative pole pin 120.
Step S300: coat sealant in the side of stopper 200.In the present embodiment, utilize suction to store and have the sponge of sealant by the side of sealant coating at stopper 200.Be specially, install a small droplet bottles at board, sealant is equipped with in the inside, and droplet bottle mouth position has a little sponge, allows stopper 200 be adjacent to little sponge and encloses to be evenly stained with sealant around one.
Step S400: fuse 100 and stopper 200 are accommodated in shell 300.
Step S500: form with a tight waist 310 of rectangle or trapezoidal groove at the shell place of stopper 200 correspondence.Shell 300 conveyer belt that fuse 100 and stopper 200 are housed is transported to die location with a tight waist, carries out pressurizing window at a tight waist 310 of the shell place of stopper 200 correspondence formation rectangle or trapezoidal groove.
In the present embodiment, step S300, after step S200, in other embodiments, can also be that step S300 is before step S200.
