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 to solve shortcoming present in prior art, and the one kind proposed is used for lithium battery
Combination plate.
To achieve these goals, the utility model employs following technical scheme：
A kind of combination plate for lithium battery, it is characterised in that：The first cover plate and the second lid including mutual cooperation
Plate, the first screw is provided with the first cover plate central, the second screw with the first screw corresponding matching is provided with the second cover plate central,
In the first screw and the second screw interior sealing connection glass capsulation set, annular is socketed in the outside of the first cover plate and the second cover plate
Plate, liquid injection hole is provided with annular slab, an end cover, the first cover plate, the second lid are tightly connected in the both sides of annular slab
Plate, glass capsulation set, annular slab and liquid injection hole are arranged between two end covers.
Preferably, first screw is identical with second Screw hole structure, is for shoulder hole, and is set in smaller hole
There are internal thread, the first screw and the second screw to form staged waist type screwed hole after coordinating, the glass capsulation set is and first
The I-shaped screw rod of screw and the second screw corresponding matching.
Preferably, the both sides of the annular slab are equipped with a ladder, external screw thread are provided with ladder, in the sealed end
The outside of lid is provided with the annular riser with ladder corresponding matching, and internal thread is provided with the inner side of annular riser.
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.
