Description
Technical field
The present invention relates to a kind of alminium electrolytic condensers, belong to aluminium electrolutic capacitor technical field.
Background technology
The production of traditional alminium electrolytic condenser is the mode to be pressed using acanthopore.As depicted in figs. 1 and 2, positive and negative anodes are led
The guide pin aluminium tongue 11 of needle 1 connect fixation with positive and negative anodes aluminium foil 2 respectively, is then wound into cylindrical shape, reassembles rubber plug and aluminum hull,
And become finished product by sealing.Wherein, by acanthopore and after pressing, riveting acanthopore 3 can be formed in the another side of guide pin aluminium tongue 11
With riveting petal 4.
This manufacturing method can be suitable for most of alminium electrolytic condenser, but in the case of width is narrow, than
If aluminium foil width 5mm and following situation or cathode foil specific volume be high, in the case of high pressure, acanthopore and press itself will
The crackle, cracking, the bad phenomenon that even severe patient also will disconnect of aluminium foil are caused, the yields of product is low, and there are wind
Danger and hidden danger.
Invention content
The technical problem to be solved by the present invention is to：How to avoid in alminium electrolytic condenser production process, because acanthopore and pressing is made
Into foil split bad problem, reduce the hidden danger of product, improve the reliability and yield rate of product.
In order to solve the above-mentioned technical problem, the technical scheme is that a kind of alminium electrolytic condenser is provided, including positive and negative anodes
Guide pin and positive and negative anodes aluminium foil, it is characterised in that：The guide pin aluminium tongue of the positive and negative anodes guide pin passes through welding with positive and negative anodes aluminium foil respectively
Mode connect and fix, positive and negative anodes aluminium foil is then wound into cylindrical shape, then in cylindrical shape external mounting rubber plug and aluminium
Shell, and form alminium electrolytic condenser by sealing, aging.
Preferably, the guide pin aluminium tongue of the positive and negative anodes guide pin and the connection mode of positive and negative anodes aluminium foil include but not limited to spot welding
Welding, laser welding.
Preferably, it after the guide pin aluminium tongue of the positive and negative anodes guide pin welds respectively with positive and negative anodes aluminium foil, is led in the positive and negative anodes
The another side of the guide pin aluminium tongue of needle forms pad.
It is highly preferred that the pad is one or more.
It is highly preferred that the shape of the pad includes but not limited to for round, diamond shape or blossom type or other any
Irregular shape.
It is highly preferred that the diameter or the length of side of the pad are the 1/2 of the guide pin aluminium tongue width of the positive and negative anodes guide pin.
Compared with prior art, alminium electrolytic condenser provided by the invention has the advantages that：
1st, alminium electrolytic condenser is produced using guide pin and aluminium foil welding manner, avoids traditional approach because of acanthopore and caused by pressing
Foil split bad problem, thus improve the reliability of product, reduce the hidden danger of product, improve the yield rate of product；
2nd, because being attached and fixing by welding, therefore the riveting impedance of product has apparent reduction, with
Traditional acanthopore mode of pressing is compared, and connection impedance is reduced to 0.2 milliohm hereinafter, therefore the present invention can have from 0.8 milliohm
Effect reduces finished product impedance.When electric current passes through junction, fever be greatly reduced, thus the service life of product also extended；
3rd, it comes off because not needing to bloom in guide pin aluminium dorsal surface of tongue to prevent guide pin, therefore guide pin and the entirety of aluminium foil junction
Size will reduce the thickness bloomed, so will be equivalent to positive pole aluminium foil can multireel around one circle, identical appearance and size its
Product capacity can promote about 5%~10%, so as to help to realize the miniaturization of product.
Description of the drawings
Fig. 1 is the alminium electrolytic condenser rearview of traditional mode that pressed using acanthopore；
Fig. 2 is the alminium electrolytic condenser side view of traditional mode that pressed using acanthopore；
Fig. 3 is alminium electrolytic condenser rearview provided in this embodiment；
Fig. 4 is alminium electrolytic condenser side view provided in this embodiment.
Specific embodiment
With reference to specific embodiment, the present invention is further explained.
The alminium electrolytic condenser rearview and side view that Fig. 3 Fig. 4 difference embodiments provide, the alminium electrolytic condenser are to use
The guide pin aluminium tongue 11 of positive and negative anodes guide pin 1 is connect and fixed with positive and negative anodes aluminium foil 2 respectively by the mode of welding, is then wound into cylinder
Shape reassembles rubber plug and aluminum hull, and becomes finished product by sealing, aging.Wherein, after welding, only in guide pin aluminium tongue 11
Another side formed pad 5.
In the present embodiment, the welding manner of guide pin aluminium tongue 11 and positive and negative anodes aluminium foil 2 includes but not limited to spot welding welding, laser
The modes such as welding.
Pad 5 can be one or more.The arrangement mode of pad and position can be in guide pin aluminium tongues 11
Any position.
The shape of pad 5 can be circle, or the other shapes such as diamond shape, blossom type or other irregular shapes
Shape.
The diameter or the length of side of pad 5 can be 1/2 or other sizes of guide pin aluminium tongue ll width.
The alminium electrolytic condenser produced using aforesaid way, avoid traditional approach because acanthopore and caused by pressing foil split it is bad
Problem, thus the reliability of product is improved, reduce the hidden danger of product, improve the yield rate of product.
In addition, because being attached and fixing by welding, therefore the riveting impedance of product has apparent reduction,
Compared with traditional acanthopore presses mode, connection impedance from 0.8 milliohm is reduced to 0.2 milliohm hereinafter, therefore guide pin and aluminium foil
The mode of welding can effectively reduce finished product impedance, and when electric current passes through junction, fever is greatly reduced, thus the longevity of product
Life also has benefited.
It comes off finally, because not needing to bloom in guide pin aluminium dorsal surface of tongue to prevent guide pin, therefore the overall dimensions at riveting will
Reduce by the thickness bloomed, so will be equivalent to positive pole aluminium foil can multireel around a circle, identical appearance and size its product holds
Amount can promote about 5%~10% (product diameter is different and different), and the miniaturization hence for product is also helpful.
The above, only presently preferred embodiments of the present invention, not to the present invention in any form with substantial limitation,
It should be pointed out that for those skilled in the art, under the premise of the method for the present invention is not departed from, can also make
Several improvement and supplement, these are improved and supplement also should be regarded as protection scope of the present invention.All those skilled in the art,
Without departing from the spirit and scope of the present invention, when made using disclosed above technology contents it is a little more
Dynamic, modification and the equivalent variations developed, are the equivalent embodiment of the present invention；Meanwhile all substantial technologicals pair according to the present invention
The variation, modification and evolution of any equivalent variations that above-described embodiment is made still fall within the range of technical scheme of the present invention
It is interior.
