Abstract
A small-sized lead-acid battery includes a shell, an inner cap, an outer cap and an electro-pad assemble formed by a positive pad, a negative pad and baffle boards in which electro liquid is filled. The lead-acid battery is characterized in that two hollow cavities and a valve block are included, the shell is a rectangular shell, a positive guide pole and a negative guide pole are further extend from the top of the electro-pad assembly, the electro-pad assembly is engaged with the shape of the rectangular shell, and the electro-pad assembly is compactly installed in the shell, the positive guide pole and the negative guide pole pierce hallow pole pillars respectively sleeved on the two guide poles, and protrude the inner cap and the outer cap, a counterbore is disposed at the center of the inner cap, and the valve block is positioned on the counterbore. With the employment of the technical scheme, connection methods such as weld connection and the like employed for pad-connection are avoided, which enables the process of manufacture and decoration to be simpler. Besides, the shell are tightly engaged with the battery pads, the structure of the battery is compact, and the large electric capacitance is controlled by the valve block, thereby preventing the electro liquid from leaking out and corroding the pads.
Description
(1) technical field
The utility model relates to a kind of battery, relates in particular to a kind of lead-acid battery.
(2) background technology
Lead-acid battery, rechargeable type lead-acid battery especially, because the advantage that it had, for example: but heavy-current discharge; Higher invertibity is arranged, can carry out hundreds of times reliably and charge and discharge circulation; Material is easy to get, low price; Aspect environmental protection, because of its material is low contaminated materials, easily recycle etc., on market, be extensive use of.
But, lead-acid battery is when possessing above-mentioned advantage, since make with assembly technology on all need adopt the hot weld method to carry out being connected of pole plate group and pole, so not only make and make the assembly technology complexity, and because of the required shell space that takies of its assembling, directly cause the utilance of battery to reduce, make lead-acid battery be difficult to miniaturization.
(3) summary of the invention
The purpose of this utility model is to provide a kind of making assembly technology easy, compact conformation, improves the small-sized lead-acid battery of production work efficiency.
A kind of small-sized lead-acid battery provided by the utility model, comprise housing, inner cap, enclosing cover, and in the housing by just, negative plate and the electrode plate assembly of forming with the dividing plate of electric liquid therebetween, be characterized in: it also comprises empty pole and a valve block in two, described housing is a rectangular housing, also just is extending respectively at the top of described electrode plate assembly, the negative utmost point that draws, this electrode plate assembly is built in wherein with cooperating the rectangular housing compact shape, and just, the negative utmost point that draws is by being nested with thereon interior empty pole stretch through out inner cap and enclosing cover respectively, the centre position of described inner cap is provided with a stepped hole, and described valve block position thereon.
Owing to adopted above-mentioned technical solution, do not need to use the hot weld method to carry out pole plate connection etc., make that the making assembly technology is more simple and feasible, in addition, housing and electrode plate assembly close fit, the battery structure compactness, capacitance is big, and, prevent that electric hydrorrhea from going out to corrode pole by valve block control.
(4) description of drawings
Fig. 1 is the utility model STRUCTURE DECOMPOSITION schematic diagram;
Fig. 2 is the utility model generalized section.
(5) embodiment
Shown in Fig. 1-2, the utility model, promptly a kind of small-sized lead-acid battery, comprise housing 1, inner cap 2, enclosing cover 3, in empty pole 5 in two, valve block 6 and the housing 1 by positive and negative pole plate and the electrode plate assembly 4 formed with the dividing plate of electric liquid therebetween.
Described housing 1 is a rectangular housing, the positive and negative utmost point 41,42 that draws is also extended at the top of described electrode plate assembly 4 respectively, this electrode plate assembly 4 is built in wherein with cooperating the rectangular housing compact shape, and the positive and negative utmost point 41,42 that draws is by being nested with thereon interior empty pole 5 stretch through out inner cap and enclosing cover respectively
The centre position of described inner cap 2 is provided with a stepped hole 21, and 6 of described valve blocks thereon.
