Abstract
The utility model discloses a square metal-shell sealing structure for a polar column of a secondary battery. An insulating cushion ring (3) and an insulating cushion (5) are clamped between a polar column (7) and an upper cover (9), the middle of the insulating cushion ring (3) is provided with a groove, and the inner wall of the groove is higher than the outer wall of the groove; an outer O-shaped sealing ring (4) is inserted in the groove, and the insulating cushion ring (3) is sheathed on the polar column. The insulating cushion ring (3) compels the outer O-shaped cushion ring (4) to be in a deformation state by a cushion ring (2) and a screw nut (1), and the convex inner wall of the insulating cushion ring (3) is inserted into an interspace between the insulating cushion (5) with steps and the polar column (7) so as to extrude an inner O-shaped sealing ring (6) to be arranged at the lower part. Pore diameter on the insulating cushion (5) is slightly larger than the outer diameter of a screw of the polar column so that the O-shaped sealing is arranged in the insulating cushion (5). The battery of the structure has no influence on the sealing rings when a cover is sealed and welded, and the problems that the battery polar column and the casing need to be both sealed and insulated are solved.
Description
Technical field
The utility model relates to battery technology, and a kind of metal shell secondary cell electrode column sealing structure is provided especially.
Background technology
Big capacity secondary battery mostly is square battery greatly, if housing is plastics or nylon, pole and case top lid sealing are convenient, simple, but plastics or nylon shell bearing capacity are low, and the battery heat dispersion is poor.Big capacity Ni-MH battery adopts metal shell mostly both at home and abroad at present, and this just requires pole and housing to seal, again insulation.
Summary of the invention
Should seal for solving pole and housing, Jue Yuan problem the utility model provides a kind of metal shell secondary cell electrode column sealing structure again.
The utility model provides a kind of metal shell secondary cell electrode column sealing structure: mainly comprise shell, loam cake, insulation cushion, insulating washer, pole, interior O RunddichtringO, outer O RunddichtringO, packing ring, nut, accompany insulating washer between pole and the loam cake, insulation cushion, be provided with groove in the middle of on the insulating washer, outer O RunddichtringO is embedded in the groove, the groove inwall is higher than outer wall, insulating washer is enclosed within on the pole, pass through packing ring, nut, insulating washer forces outer O RunddichtringO to be deformation state, the inwall of insulating washer projection inserts in the space of insulation cushion with step and pole, extruding is located at the interior O RunddichtringO of bottom, the aperture is more bigger than pole screw external diameter on the insulation cushion, and the O RunddichtringO therein in making.
The material of described insulating washer and insulation cushion is nylon 66 or other alkaline-resisting heatproof insulating properties material, and O RunddichtringO material is ethylene propylene diene rubber or other alkaline-resisting temperature resistant rubber.
The utility model is the middle groove that is provided with on insulating washer, outer O RunddichtringO is embedded in the groove, the groove inwall is higher than outer wall, insulating washer is enclosed within on the pole, by packing ring, nut, insulating washer forces outer O RunddichtringO to be deformation state, the inwall of insulating washer projection inserts in the space of insulation cushion with step and pole, extruding is located at the interior O RunddichtringO of bottom, height by control insulating washer depth of groove, projection, control inside and outside O RunddichtringO deflection, make deflection satisfy sealing and insulating requirements between pole and shell.
