As shown in figure 1, a kind of high leakproofness electrolysis condenser, including housing 1, the top of described housing 1 is provided with cover plate
2.In the present embodiment, the material of described cover plate 2 can be divided into two parts, and top is phenolic materials, and periphery is rubber layer, from rubber
The reason glue-line, is because that quality of rubber materials is soft, has preferable sealing effectiveness, and can fix well.Described cover plate can also it
Its material, as long as enable to coordinate with the sealing of described housing.
Be provided with core bag in described housing 1, described core bag draws chaff by positive pole and negative pole draw chaff respectively with positive terminal
Terminal and negative terminal communicate, and described both positive and negative polarity binding post can be fixed on described cover plate 2 by welding terminal, described
Cover plate 2 is provided with the matching hole matching with described both positive and negative polarity binding post, and described matching hole is used for making described positive terminal
Son 5, described negative terminal 6 draw chaff by positive pole described in this Kong Bingyu, described negative pole draws chaff and connects.
It is provided with the crimping 11 of the inside turnup of a circle, in the present embodiment, described crimping 11 is concrete at the opening of described housing 3
It is arranged at the upper end open structure of described housing 3, the top of described cover plate 2 is connected with the crimping 11 at described housing 1 opening,
In mating process, achievable described cover plate 2 is fixedly connected with described housing 3, and then ensures the steady of described electrolysis condenser
Solidity.Described housing 3 forms the structure of lower end closed upper end open by cold extrusion, is additionally provided with cladding on described cover plate 2
Connect the sealant layer 4 in area, compared with prior art, the setting of described sealant layer structure makes described electrolysis condenser have more
Strong sealing property, described electrolysis condenser needs not worry about electrolyte leakage in use and described electrolysis condenser is easy
Come off.In the technical program, described sealant layer 4 can be arbitrary shape, for example: circular, oval or circulus, as long as
Enable the sealing of described housing and described cover plate, in the present embodiment, described sealant layer 4 is circulus, described
The setting of circulus can make the sealing effectiveness of described electrolysis condenser more preferably, and also has working stability at high operating temperatures
