Description
Technical field
The utility model relates to a kind of storage battery.
Background technology
At present, the involution mode of battery cap and cell jar has two kinds: heat-sealing and rubber seal.The sealing of terminal and battery cap is all adopt glue seal technology: first battery terminal is passed the terminal hole on battery cap, again spiral compression ring, sealing ring are enclosed within accumulator terminal, then spiral compression ring compression stage column sealing circle is screwed, sealing ring is made to be tamping terminal, fill the space of terminal, sealing ring, hold-down ring and terminal hole formation again with epoxy resin sealant, thus form the sealing device of accumulator terminal.
But, there is following drawback in prior art: 1, easily cause dry joint, rosin joint when accumulator terminal and lug fusion weld, have a strong impact on product quality, cause product rejection; 2, the harmful components contaminated environment of epoxy resin sealant while, epoxide-resin glue longer curing time to cause the cycle of the production of storage battery increase by 3 and also the copper insert of anode and cathode terminals obviously do not distinguish, without error-disable function when coordinating with battery cap, easily cause the antipole of storage battery; 4, to stretch out the height of battery cover inconsistent for copper insert.
Summary of the invention
In order to solve above-mentioned drawback, technical problem to be solved in the utility model is, provides a kind of storage battery, can simplify production technology, improve the quality of products, shortens the production cycle, reduce environmental pollution.In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of storage battery, comprise safety valve, positive and negative terminal, battery cover, battery case, pole plate group and electrolyte, described terminal is made up of copper insert, plumbous body, and described copper insert is embedded in plumbous body, it is characterized in that, described copper insert is made up of pole, and the outer surface on copper insert top is provided with threaded portion; Ring-type jog is provided with in the middle part of copper insert; Annular boss portion is provided with bottom copper insert; The bilateral symmetry of described threaded portion is provided with cutting portion; The facade of cutting portion forms terminal position face, the terminal position face of the copper insert of positive and negative terminal towards difference, the pole column hole of described battery cap is provided with supporting cap bore locating surface corresponding to terminal position face; The bottom stage of cutting portion forms limit for height bottom surface, and the pole column hole of described battery cap is provided with the limit for height capping with described limit for height bottom surface corresponding matching; The bilateral symmetry in described annular boss portion is provided with anti-rotation face, and described anti-rotation face and locating surface correspondence stagger 90 degree;
Described plumbous body is provided with annular boss, and the upper surface of annular boss is provided with semi-circular recesses, and described sealing ring lower surface is provided with semicircle boss, and described semi-circular recesses is corresponding with semicircle boss to coincide; Described plumbous body is provided with the jockey of comb teeth-shaped, and pole plate lug is inserted between the comb of jockey, and the both sides of each comb are set to chamfering structure.
Adopt technique scheme, because comb both sides are designed to chamfering, lug inserts the space defining an inverted triangle between the lug after comb and comb, and during welding, flame directly reaches bottom by the space of triangle of leaning now to one side, then to the other, the depth of weld increases, and welds more thorough; Be surprised to find that simultaneously, be arranged to chamfering structure, although make the lead amount of both contact-making surfaces reduce, this structure is conducive to the combination of comb and lug fused solution, increases the fusion area of lug and comb on the contrary; Not only stop the phenomenon of dry joint and rosin joint, made quality of connection reliable, improve the quality of products; And add the conductive area that lug and bus terminal arrange, thus reduce the internal resistance of whole storage battery, improve the charge acceptance of storage battery, extend the life-span of storage battery.
The difference in the direction, terminal position face of positive and negative terminals, can not produce reverse electrode phenomena when coordinating with battery cover.The cooperation of limit for height bottom surface and limit for height capping, makes terminal copper insert exceed the height of battery cap completely the same, thus ensure that the height overall of storage battery is consistent; Copper insert is provided with threaded portion, and terminal and battery cap by sealing ring press seal by nut, are made the sealing of whole accumulator terminal not re-use epoxide-resin glue, improve environment; And after terminal sealing, storage battery at once can acid dosing and charging, does not need to wait more than 12 hours again, shortens the production cycle, improve production efficiency.
In sum, the beneficial effects of the utility model are, improve the quality of products, and simplify the production technology of storage battery, shorten the whole production cycle, improve environment, be applicable to industrial production.
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
