Description
Technical field
It the utility model is related to cell art, more particularly to a kind of lithium battery end cap.
Background technology
Column type lithium cell is the novel power supply product to grow up in recent years, and with its high-energy-density, open-circuit voltage is high, makes
With strength range is wide, stable operating voltage, service life is long, self-discharge rate is low, storage life is long, the fine quality such as nuisanceless,
It is widely used in the fields such as smart card meter, computer Power Support, medical device, wireless telecommunications, scientific research apparatus.
In the structure of lithium battery, lid group is its critical component, at present both at home and abroad in the lid group of manufacturer production
Sintered glass sealing shroud is right cylinder type, and it has the disadvantage that：The cylinder and bottom plate sealing-in area of glass capsulation set are small, bear battery
Internal pressure is small；Glass insulator amount is small, proper alignment heat differential, easily causes glass crack, causes leakage to fail.
Utility model content
The purpose of this utility model is and a kind of lithium battery end proposed in order to solve shortcoming present in prior art
Lid.
To achieve these goals, the utility model employs following technical scheme：
A kind of lithium battery end cap, it is characterised in that：Including cover plate, screwed hole is provided with cover plate central, it is close in screwed hole
Envelope connection glass capsulation set, the connection electrode lead in glass capsulation set, on the cover board provided with liquid injection hole, in screwed hole both sides point
Not She You a groove, a neck is equipped with the outside of each groove, equal fitted seal connects one in two grooves
End cover, the annular riser of clamping engagement corresponding with respective card slot is provided with the outside of the end cover.
Preferably, two grooves are symmetrical arranged.
Preferably, the liquid injection hole is arranged on the outside of the groove.
The utility model has the advantage of：The present apparatus bears that cell internal pressure is big, and glass insulator weight is big, proper alignment
Hot property improves, and after fusion welding, is not likely to produce crackle, solves the problems, such as battery leakage rate, improves lithium battery qualification rate, can
Product structure is allowed to develop to small miniaturization, lighting；The pressure-resistant and resistant to leakage performance of product is improved.
