Abstract
The utility model relates to a cover assembly for column lithium batteries, comprising a cover plate (1), an electrode leading wire (3) and a glass sealing sleeve (2). The cover assembly is characterized in that a step (2a) is arranged on the outer column of the glass sealing sleeve, and the step is connected with a step hole in the cover plate in a matching way; and the glass sealing sleeve with the step which is adapted to the step hole in the cover plate is formed by high temperature sintering. The utility model has the advantages that with the structure, the pressure resistant and leak resistant performances of products can be approximately increased by two times to solve the problems of air leakage, liquid leakage and insufficient pressure resistance, and the like when the products are used by users; the large sealing area of the glass and a bottom plate can bear greater inner pressure of the batteries; a glass insulator is heavy, the welding heat-resistant performance is improved, and cracks are not easy to produce after fusion welding, thus the problem of the liquid leak rate of the batteries can be solved and the pass rate of the lithium batteries can be improved.
Description
Technical field:
The utility model relates to column type lithium cell, and particularly column type lithium cell is with the architecture advances of lid group.
Background technology:
Column type lithium cell is the novel power supply product that grew up in recent years,, stable operating voltage, long service life wide with its high-energy-density, open circuit voltage height, working strength scope, self-discharge rate is low, storage life is long, fine quality such as nuisanceless, be widely used in fields such as smart card meter (water, electricity, gas table), computer Power Support, medical device, wireless telecommunications, scientific research apparatus, the lithium battery industry had obtained fast development in recent years, product quality also constantly improves, substitute import, and export to the overseas market.In the structure of lithium battery, the lid group is its critical component, and the sintered glass sealing shroud in the lid group of at present domestic and international manufacturer production is the right cylinder type, and it has following shortcoming: the cylinder and the base plate sealing-in area of glass capsulation cover are little, and it is little to bear cell internal pressure; The glass insulator amount is little, and anti-sweating heat is poor, easily causes glass crack, causes leakage to lose efficacy.
The utility model content:
The purpose of this utility model is exactly that to overlap existing sealing-in area little in order to overcome right cylinder glass capsulation in the prior art, bear cell internal pressure little, easily cause leakage defect, and a kind of improved column type lithium cell that proposes at this shortcoming is organized with lid.
To achieve these goals, the utility model has been taked following technical scheme:
A kind of column type lithium cell is used and is covered group, and it is made up of cover plate, contact conductor and glass capsulation cover, it is characterized in that the outside cylinder that glass capsulation overlaps is provided with step, the sealing that is connected of the stepped hole in this step and the cover plate.Glass capsulation cover is by high temperature sintering, form with cover plate in the stepped hole glass capsulation cover that has step of fitting mutually.
Owing to adopted technique scheme, made to the utlity model has following advantage: can allow the product structure structure to little microminiaturization, the lighting development; In size product of the same race, adopt this kind structure can allow product performance in withstand voltage and anti-leakage improve nearly 1 times; Can solve problems such as gas leakage that the user exists in using, leakage, withstand voltage deficiency; The area of glass and base plate sealing-in is big, bears cell internal pressure and increases; Glass insulator weight is big, and anti-sweating heat performance improves, and after the melting, is difficult for cracking, and has solved battery leakage rate problem, has improved the lithium battery qualification rate.
Description of drawings:
Fig. 1 is a cutaway view of the present utility model.
Embodiment:
As shown in Figure 1, the column type lithium cell that the utility model provides is used and is covered group, and it is made up of cover plate 1, contact conductor 3 and glass capsulation cover 2, and cover plate 1 is provided with liquid injection hole 4, the outside cylinder that it is characterized in that glass capsulation cover 2 is provided with step 2a, and the stepped hole in this step and the cover plate is connected.Glass capsulation cover 2 is by high temperature sintering, form with cover plate in the stepped hole glass capsulation cover that has step of fitting mutually.The wing position of cover plate 1 and outer steel shell carry out melting (welding such as argon arc welding, Laser Welding, plasma welding) temperature and reach more than 1500 ℃.Positive wire 3 is carried out glass sealing with the glass capsulation cover in the cover plate.This structure goes for glass sealing series column type lithium cells such as circle, square, rectangle and organizes with lid.
