Abstract
A lead-acid battery output structure composed of positive and negative lead bushings and positive and negative lead poles in an upper cover, wherein the inner diameter of the positive lead bushing is phi 15-25 mm, the alloy is the same as a positive grid, and lead-antimony alloy containing 1.5-5% of antimony is adopted; the outer diameter of the positive lead pole is 0.3-1.0 mm smaller than the inner diameter of the positive lead bushing, and the alloy of the positive lead pole is the same as that of the positive lead bushing; the inner diameter of the negative lead bushing is 1.5-2.0 mm smaller than that of the positive lead bushing, the alloy of the negative lead bushing is the same as that of the negative grid, and a lead-calcium-tin alloy containing 0.5-1.5% of calcium and 1.0-2.0% of tin is adopted; the outer diameter of the negative lead pole is 0.3-1.0 mm smaller than the inner diameter of the negative lead bushing, and the alloy of the negative lead pole is the same as that of the negative lead bushing. By adopting the output structure, the battery can be effectively prevented from inverting; intergranular corrosion is not generated when the electrode group is welded, and the service life of the battery is prolonged; the intergranular corrosion is not generated when the pole is welded, and the sealing performance of the battery is improved.
Description
Technical field
The utility model relates to a kind of lead acid accumulator export structure, belongs to the lead-acid battery field.
Background technology
The present lead acid accumulator export structure of being made up of both positive and negative polarity lead bushing in the loam cake and both positive and negative polarity lead terminal post is because both positive and negative polarity lead bushing size is the same, alloy is the same, is generally lead-antimony alloy; Both positive and negative polarity lead terminal post size is the same, alloy is the same, the general terne metal that adopts, and it is different with the plate railings of anode and cathode alloy, the problem of being brought is: (one) both positive and negative polarity lead bushing size is the same, the positive and negative terminals size is the same, and reverse electrode phenomena very easily takes place when both cooperate, in case take place, to battery is fatefulue injury, the accident that can blast; (2) positive and negative terminals and plate railings of anode and cathode alloy are different, can produce intercrystalline corrosion at welding utmost point group time, influence battery useful life; (3) both positive and negative polarity lead bushing and both positive and negative polarity lead terminal post alloy are different, can produce intercrystalline corrosion at welding utmost point group time, influence the sealing property of battery, easily produce and leak.
Summary of the invention
The purpose of this utility model is to overcome weak point of the prior art, provides a kind of and prevents to export antipole, improves battery life, prevents the lead acid accumulator export structure of battery drain.
The technical solution of the utility model is: the lead acid accumulator export structure comprises and is fixed on the both positive and negative polarity lead bushing that covers and corresponding matching and have the both positive and negative polarity lead terminal post of gap A with it, the latter links to each other with positive and negative grid respectively, it is characterized in that negative electrode lead lining internal diameter is less than anodal lead bushing internal diameter, difference is B, and B＞A; In addition, anodal lead bushing, anodal lead terminal post are identical with positive grid alloy material, and negative electrode lead lining, negative electrode lead pole are identical with the negative plate grid alloy material.
Described anodal lead bushing internal diameter is φ 15～25mm, and described gap A is 0.3～1.0mm.Difference B is 1.5～2.0mm.The alloy material of anodal lead bushing, anodal lead terminal post and anode plate grid is the lead-antimony alloy that contains antimony 1.5～5%.The alloy material of negative electrode lead lining, negative electrode lead pole and negative electrode grid is the lead-calcium-tin alloy of calcic 0.5～1.5%, tin 1.0～2.0%.
Adopt above technical scheme, both positive and negative polarity lead bushing size is different, the positive and negative terminals size is different, and anodal lead bushing cooperates with anodal lead terminal post, the negative electrode lead lining matches with negative terminal, if anti-the loam cake lid when battery is assembled so because of carelessness,, effectively prevent the battery antipole in any case loam cake is that lid does not go down yet; Positive and negative terminals is the same with grid alloy, can not produce intercrystalline corrosion welding utmost point group, improves battery useful life; The both positive and negative polarity lead bushing is the same with both positive and negative polarity lead terminal post alloy, can not produce intercrystalline corrosion when the welding pole, improves the sealing property of battery.
