By argon arc or laser seal welding, hollow cylinder (03) aperture is greater than for the through hole of battery case cap and hollow cylinder (03)
Pole outer diameter and be less than pole end (09) cross-sectional outer diameter.Pole (01) is inserted into the cylinder through hole on battery case cap, so
Compression seal casing (04), insulation spacer (05), insulating washer (06), metal washer (07) successively are assembled in pole afterwards, is passed through
It compresses locking nut (08) and compresses sealing sleeve pipe (04) sealing pole (01) and through hole, reach the close effect of liquid.
Further, compression seal casing (Fig. 2) is in the sub- shape of back taper, and sealing sleeve pipe (04) internal diameter is less than pole (01) column
External diameter, material are to contain one or more of rubber, polytetrafluoroethylene (PTFE), nylon, polypropylene composite material.
Further, the surface roughness of the sealing surface of pole (01) and cap cylinder through hole is 20 μm or smaller.
The beneficial effects of the present invention are: method for sealing polar post according to the present invention, compared with the past technique is simpler, can
The fluid tight of battery post is greatly improved with the synergistic action effect by each component, prevents leakage.
