The utility model content:
The purpose of this utility model is exactly that a kind of plastic seal type lithium battery that provides is organized with lid for the lid group positive wire that overcomes in the prior art adopts glass sintering to be connected the anti-sweating heat of existing glass insulator shortcoming poor, that easily cause glass crack, leakage to lose efficacy with cover plate.
To achieve these goals, the utility model has been taked following technical scheme:
Center cellular type plastic seal type lithium battery is used and is covered group, and it is made up of cover plate, contact conductor, it is characterized in that: the contact conductor center is provided with liquid injection hole.After fluid injection finishes, adopt methods such as metal melting welding, liquid injection hole is sealed.
On the basis of above-mentioned basic technical scheme, can increase following further technical scheme:
Contact conductor is a T pin configuration, connect a plastic sealing cover in the cover plate, the column part that plastic seal is arranged with centre bore and T head lead-in wire is sealed and matched, the two ends up and down of plastic sealing cover are respectively equipped with loam cake, lower cover, the upper and lower surface of they and cover plate compresses and is sealed and matched, and the stylolitic part of the cannelure that forms between the loam cake of plastic sealing cover, the lower cover is tightly connected with the centre bore of cover plate and cooperates.
The loam cake that the head of T head lead-in wire is provided with protruding ring and plastic sealing cover compresses and is sealed and matched.The lower cover that the lower surface of cover plate is provided with protruding ring and plastic sealing cover compresses and is sealed and matched.Plastic sealing cover following is covered with one section barrel, wherein is provided with the column part of packing ring and T head lead-in wire and lower cover end face and compresses and be sealed and matched.
More than all technical characterictics all be the effective measures that adopt in order to improve sealing property, and adopt plastic sealing cover, again the processing technology of Jian Huaing, reduced cost.
Owing to adopted technique scheme, make and the utlity model has following advantage: performance can compare favourably with the glass sintering product in withstand voltage and anti-leakage, but it is longer that its cost significantly reduces, covers the storage life time of Battery pack, can allow the product structure structure to little microminiaturization, the lighting development.
