Description
Technical field
The present invention relates to a kind of sealing structure, and in particular to a kind of battery-end column sealing structure.
Background technology
Existing colloid battery newel post sealing structure is easily inclined by pole and cushion rubber dimensional discrepancy, surface roughness and assembly manipulation
Difference etc. a series of impact of unstable factors and cause cooperation to accomplish to fully seal, and then occur newel post sealing difference cause Lou
Acid, climb sour phenomenon, and corrosion is caused to junction point and associated components, have influence on normally using for battery, must enter after leakage acid
Row cleaning produces pollution to environment again, and current carrying capacity and high current safety cannot be ensured.
The content of the invention
Goal of the invention：The invention aims to overcome deficiency of the prior art, there is provided a kind of good seal performance, acid
Liquid is non-leakage, it is to avoid electrolyte leakage causes thermal runaway, reduces corrosion risk, reduces internal resistance, improves current carrying capacity and guarantor
The new colloidal electrokinetic cell newel post sealing structure of card high current security performance.
Technical scheme：In order to solve above-mentioned technical problem, a kind of new colloidal electrokinetic cell newel post of the present invention is close
Seal structure, it includes copper terminal, O-shaped sealing ring, pond lid newel post connector and taper lead terminal post composition, the copper terminal
For square terminal, welding hole is provided with described copper terminal one end, fixing hole is provided with by the welding hole, in the Chi Gai
Newel post's connector is provided with pond lid newel post hole, annular groove is provided with above the pond lid newel post hole, by the annular groove
Terminal fixed column is provided with, by the terminal fixed column terminal limiting card is provided with.
On taper lead terminal post, the O-shaped seal ring set is arranged on the pond lid newel post borehole jack on taper lead terminal post
In ring groove, the welding hole is enclosed within taper lead terminal post, and the fixing hole is enclosed within terminal fixed column.
The welding hole is enclosed within taper lead terminal post, and junction is welded with tin welding wire.
Primer and red blue glue are provided with the copper terminal.
The O-shaped sealing ring is acid-proof RUBBER O type sealing ring.
Taper lead terminal post periphery of the present invention is tight with the newel post's ring groove hole inwall on battery cover using acid-proof elastomeric O-rings
Close fit, makes acid-proof elastomeric O-rings strengthen with the downward adhesion of taper lead block, while the newel post's ring groove hole limit on battery cover
Acid-proof elastomeric O-rings dilatancy processed is so that acid-proof elastomeric O-rings and the newel post's ring groove on taper lead block and battery cover
What is coordinated is tightr, while being formed, copper terminal bottom Jie Zu faces are smooth to be conducive to welding quality and upper terminal primer, sealing effect
More preferably, the battery newel post phenomenon of leakage is controlled fruit compared with traditional colloid power battery-end column sealing structure, is produced and is used
Process temperature will not be out of control, and battery charging and discharging internal resistance is obviously reduced, and current carrying capacity and high current security performance are protected.
Beneficial effect：Compared with prior art, its remarkable advantage is the present invention：Present configuration is simple, when O-shaped sealing ring
Positive and negative taper lead terminal post upper end is enclosed within, is moved in the lid positive and negative terminal post holes bottom groove of pond to lower stress with specific purpose tool, made O-shaped
Sealing ring strengthens with the downward adhesion of taper lead block, while bottom hole portion of the newel post ring groove hole on battery cover limits O-shaped sealing
Ring dilatancy, so that O-shaped sealing ring is even closer with what taper lead block and battery cover newel post bottom hole portion ring groove coordinated,
It is prevented effectively from newel post's leakage acid, climbs acid corrosion terminal and junction point associated components, the problem of environmental pollution of effective control production process,
Clean manufacturing is realized, additionally, terminal has a fixed column and two side limiting cards to prevent terminal welding bias effect terminal welding matter
Amount, strengthening electric current bearing capacity and high current safety.
Description of the drawings
Fig. 1 is each modular construction schematic diagram of the present invention；
Fig. 2 is the mounting structure schematic diagram of the present invention.
Specific embodiment
With reference to the accompanying drawings and examples the present invention is further illustrated.
As depicted in figs. 1 and 2, a kind of new colloidal electrokinetic cell newel post sealing structure of the present invention, it includes copper
Matter terminal 1, O-shaped sealing ring 2, pond lid newel post connector 3 and taper lead terminal post 4 are constituted, the copper terminal 1 for square end
Son, in described one end of copper terminal 1 welding hole 5 is provided with, and fixing hole 6 is provided with by the welding hole 5, is connected in the pond lid newel post
Fitting 3 is provided with pond lid newel post hole 7, and in the top of the pond lid newel post hole 7 annular groove 8 is provided with, and sets by the annular groove 8
There is terminal fixed column 9, by the terminal fixed column 9 terminal limiting card 10 is provided with；The pond lid newel post hole 7 is enclosed within taper lead pole
On post 4, the O-shaped sealing ring 2 is enclosed within taper lead terminal post 4, and is arranged in ring groove 8, and the welding hole 5 is enclosed within taper
