Abstract
The utility model belongs to an aluminum electrolytic capacitor which is suitable for various electric appliances and is composed of a housing, a core bag, a current guide wire of the core bag, a phenolic aldehyde cover plate, a welding sheet, etc. The aluminum electrolytic capacitor is characterized in that the lower part of the welding sheet is connected with a hollow riveting pipe into a whole in a sickle shape, and a concave rubber sealing plug is inlaid in a groove of the phenolic aldehyde cover plate. The utility model has the advantages of reasonable structure, easy implementation, convenient assembly, small contact resistance, good sealing performance and the ability of improving the use properties of the capacitor.
Description
The utility model belongs to a kind of aluminium electrolytic capacitor, is applicable to various electric equipment products.
In the prior art, the zinc-plated antimony iron weld tabs in its structure of aluminium electrolytic capacitor is all fixedlyed connected by plumbous rivet with the phenol glue cover plate.Adopt this Mechanical Contact fixed structure, not only need to adopt welding in the ultrasonic wave, complicated operation, and weld tabs needs through chemical cleaning, especially the oxide layer that the easy generation of weld tabs spare can not be stable, cause weld tabs and rivet contact site resistance to increase, this milliohm level contact resistance produces, and certainly will directly influence the serviceability of capacitor.
The utility model is intended to overcome the problem that prior art exists, and it is reasonable to propose a kind of connection, and drainage is reliable, and cover plate exit contact resistance is tending towards the aluminium electrolytic capacitor of null value.
Accompanying drawing 1, the structural representation of aluminium electrolytic capacitor.
Accompanying drawing 2, the B-B cutaway view of accompanying drawing 1.
Concrete structure of the present utility model and situation are described below by reference to the accompanying drawings:
Shown in accompanying drawing 1-2, this capacitor is by shell (1), stamen bag (2), stamen bag drainage thread (3), phenolic aldehyde cover plate (4), and weld tabs (6) etc. is constituted.Its main points are: the bottom of weld tabs (6) and a hollow riveting pipe (D) are connected as a single entity, and are the whole stamping parts of same metal material, and the whole shape of weld tabs (6) is sickle shaped; Phenolic aldehyde cover plate (4) is embedded in spill rubber seal plug (5) groove (sealing plug (5) has fairlead).
During the electrolytic capacitor assembling, stamen bag drainage thread (3) inserts hollow riveting pipe (D), and the end of a thread of stamen bag drainage thread (3) becomes connection status with weld tabs (6) through soldering, and (7) are metallic gaskets, (S) are tin welding spot.
The utility model compared with prior art, and is not only rational in infrastructure, implement easily, easy to assembly, and contact resistance is minimum, and good seal performance has improved the serviceability of product widely.
Claims (1)
1, a kind of aluminium electrolytic capacitor, it is by shell (1), stamen bag (2), stamen bag drainage thread (3), phenolic aldehyde cover plate (4), weld tabs (6) etc. constitute, and it is characterized in that weld tabs (a 6) bottom and a hollow riveting pipe (D) shape that is connected as a single entity is the reaping hook shape; Phenolic aldehyde cover plate (4) embeds one and is in rubber seal plug (5) groove of spill.
