Abstract
A kind of entitled terminal structure that can effectively extend battery life of the utility model.Belong to Lead-acid Battery Technology field.It mainly improves existing lead-acid storage battery terminal presence and climbs acid or the phenomenon of leakage to extend battery life.Being mainly characterized by comprising: for it includes annular flange, the annular acid leakage-proof ring below annular flange that cylinder type Anti-acid-leakage lead ring and cylinder type Anti-acid-leakage lead ring radially-outer surface outwardly protrude；The upper surface of the annular acid leakage-proof ring is low inside and high outside circular slanting slope surface, and lower end surface is equipped with inner groovy recessed upwards.The utility model has the characteristics that acid solution can be effectively blocked, prevents from seeping acid, is mainly used for extending service life of lead accumulator.
Description
Technical field
The utility model belongs to Lead-acid Battery Technology field, and in particular to a kind of terminal that can effectively extend battery life
Structure.
Background technique
It is technology urgently to be resolved in a universal phenomenon and industry that lead-acid storage battery terminal, which climbs acid in battery industry,
One of problem.Since terminal material is different from battery cover material, the coefficient of expansion is different, under the influence of ambient temperature, end
Small gap, through a long time capillary phenomenon are formed between son and lid, the exudation cell cover from gap of acid solution slowly generates
Acid or the phenomenon of leakage, corrosion cell terminal and binding post are climbed, battery premature failure is caused.Environment is not only polluted, when serious even
Vehicle body can be corroded, generate security risk.
Summary of the invention
The goal of the invention of the utility model be for the above-mentioned insufficient of the prior art and provide one kind can be effectively blocked acid solution,
Prevent from seeping the acid leakage-proof terminal of accumulator of acid, effectively to extend battery life.
The technical solution of the utility model is: a kind of terminal structure that can effectively extend battery life, including cylinder
Annular below annular flange that type Anti-acid-leakage lead ring and cylinder type Anti-acid-leakage lead ring radially-outer surface outwardly protrude, annular flange
Acid leakage-proof ring, it is characterised in that: the upper surface of the annular acid leakage-proof ring is low inside and high outside circular slanting slope surface, and lower end surface is equipped with
Recessed inner groovy upwards.
Annular flange lower part described in the technical solution of the utility model and battery big cover engaging portion are equipped with anti-creep
Sour groove.
There are three annular acid leakage-proof rings described in the technical solution of the utility model.
There are three annular acid leakage-proof rings described in the technical solution of the utility model；The acid leakage-proof groove is
Three, between the acid leakage-proof groove respectively formed between annular flange and annular acid leakage-proof ring and three annular acid leakage-proof rings
The two acid leakage-proof grooves formed.
The side end face of annular acid leakage-proof ring described in the technical solution of the utility model is under upper end diameter is greater than
Hold the arcwall face of diameter.
Inner groovy described in the technical solution of the utility model is the inner groovy that section is ellipse.
Annular flange bottom described in the technical solution of the utility model is equipped with transverse bar and vertical muscle.
Cylinder type Anti-acid-leakage lead ring described in the technical solution of the utility model is stamping terminal, material
For metal.
The utility model the advantages of be:
1, terminal lower portion is equipped with tricyclic slope, can increase electrolyte climbing difficulty, be convenient for acid solution free-falling；
2, terminal lower portion is equipped with tricyclic annular groove, to extend terminal path in conjunction with plastic parts, increases electrolyte and climbs
The resistance climbed, acid solution are not easy to climb out of, and acid solution is effectively prevent to leak upwards；
3, terminal lower portion is equipped with vesica piscis connected in star, and acid solution is snapped down to terminal lower portion from round wall surface, effectively prevent acid
Liquid leaks upwards.
Detailed description of the invention
Fig. 1 is the cut-away view of the utility model.
In figure: 1. cylinder type Anti-acid-leakage lead rings；2. annular flange；3. battery big cover；4. inner groovy；5. annular is anti-
Climb sour ring；6. annular ramp.
Specific embodiment
The utility model is further described with specific example below, this specific example is in order to furtherly
The feature and feature of bright the utility model are not the limitation to the utility model claims.
As shown in Figure 1.A kind of terminal structure of the limited extension battery life of energy of the utility model
Including the convex annular outwardly protruded on 1 middle part lateral wall of cylinder type Anti-acid-leakage lead ring 1 and cylinder type Anti-acid-leakage lead ring
Annular acid leakage-proof ring 5 below edge 2, annular flange 2.Wherein, cylinder type Anti-acid-leakage lead ring 1 is stamping terminal, material
For metal.The section vertical section of annular flange 2 is step-like.The lateral surface and 3 type chamber inner sidewall of battery big cover of annular flange 2
It coincide, the side surface of terminal of upper surface and battery big cover 3 is horizontal, and transverse bar and vertical muscle are arranged at bottom.2 lower part of annular flange and battery big cover
Have annular acid leakage-proof ring 5 on 1 lateral wall of cylinder type Anti-acid-leakage lead ring of binding site, altogether there are three.Annular acid leakage-proof ring 5 it is upper
End face is low inside and high outside circular slanting slope surface, and lower end surface is equipped with inner groovy 4 recessed upwards, and side end face is under upper end diameter is greater than
Hold the arcwall face of diameter.Inner groovy 4 is the inner groovy that section is small ellipse.2 lower part of annular flange and battery big cover engaging portion
Equipped with 3 acid leakage-proof grooves, the acid leakage-proof groove and three rings respectively formed between annular flange 2 and annular acid leakage-proof ring 5
The two acid leakage-proof grooves formed between shape acid leakage-proof ring 5.
This can make the contact between cylinder type Anti-acid-leakage lead ring 1 and battery big cover 3 more closely, effectively closure acid solution, show
Work prevents from climbing acid, effectively extends the terminal service life.When the big lid of the utility model Anti-acid-leakage lead ring injection molding battery, according to normal process into
Row production, saves unnecessary material and cost of labor, optimizes process, and lead circle produces automatic code-disc, promotes battery production efficiency.
