Description
Technical field
The present invention relates to a kind of hermetically-sealed construction, be specifically related to a kind of battery-end column sealing structure.
Background technology
Existing colloid battery newel post hermetically-sealed construction is subject to the impact of a series of destabilizing factor such as pole and cushion rubber dimensional discrepancy, surface roughness and assembly manipulation deviation and causes cooperation can not accomplish to seal completely, and then occur that newel post's sealing difference causes Lou acid, climbs sour phenomenon, and corrosion is caused to tie point and associated components, have influence on the normal use of battery, must carry out after leaking acid clearing up and producing environment polluting, current carrying capacity and big current fail safe can not get ensureing.
Summary of the invention
Goal of the invention: the object of the invention is to overcome deficiency of the prior art, a kind of good seal performance is provided, acid solution is non-leakage, electrolyte leakage is avoided to cause thermal runaway, reduce corrosion risk, reduce internal resistance, improve the new colloidal electrokinetic cell newel post hermetically-sealed construction of current carrying capacity and guarantee big current security performance.
Technical scheme: in order to solve the problems of the technologies described above, a kind of new colloidal electrokinetic cell newel post of the present invention hermetically-sealed construction, it comprises copper terminal, O type sealing ring, pond lid newel post connector and taper lead terminal post composition, described copper terminal be square terminal, welding hole is provided with in described copper terminal one end, fixing hole is provided with on described welding hole side, described pond lid newel post connector is provided with pond lid newel post hole, annular groove is provided with above described pond lid newel post hole, terminal fixed leg is provided with on described annular groove side, terminal limiting card is provided with on described terminal fixed leg side.
Described pond lid newel post borehole jack is on taper lead terminal post, and described O type seal ring set on taper lead terminal post, and is arranged in ring groove, and described welding hole is enclosed within taper lead terminal post, and described fixing hole is enclosed within terminal fixed leg.
Described welding hole is enclosed within taper lead terminal post, and junction tin welding wire welds.
Described copper terminal is provided with primer and red blue glue.
Described O type sealing ring is acid-proof RUBBER O type sealing ring.
Taper lead terminal post periphery of the present invention adopts the newel post's ring groove hole inwall on acid-proof elastomeric O-rings and battery cover to closely cooperate, acid-proof elastomeric O-rings and the downward adhesion of taper lead block are strengthened, newel post's ring groove hole restriction acid-proof elastomeric O-rings dilatancy simultaneously on battery cover thus acid-proof elastomeric O-rings is coordinated with the newel post's ring groove on taper lead block and battery cover tightr, formed simultaneously and bottom copper terminal, to tie that sufficient face is smooth is conducive to welding quality and upper terminal primer, sealing effectiveness is better, the battery newel post phenomenon of leakage is controlled compared with traditional colloid power battery-end column sealing structure, manufacture and usage process temperature can not be out of control, battery charging and discharging internal resistance obviously reduces, current carrying capacity and big current security performance are protected.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: structure of the present invention is simple, when O type seal ring set is in positive and negative taper lead terminal post upper end, move in the lid positive and negative terminal post holes bottom groove of pond with specific purpose tool to lower stress, O type sealing ring and the downward adhesion of taper lead block are strengthened, ring-like recess hole restriction O type sealing ring dilatancy bottom newel post hole simultaneously on battery cover, thus make the tightr of ring-like groove fit bottom O type sealing ring and taper lead block and battery cover newel post hole, newel post is effectively avoided to leak acid, climb acid corrosion terminal and tie point associated components, the problem of environmental pollution of effective production control process, realize cleaner production, in addition, terminal has a fixed leg and two side limiting cards to prevent terminal soldering bias effect terminal soldering quality, strengthen current carrying capacity and big current fail safe.
