Abstract
A grid plate of lead-acid accumulator comprises a grid plate frame which is provided with grates and grids that are spliced by the grates. The grids are filled with active substance. The grates are divided into two groups. One group extend from a left upper corner of the grid plate frame to a right lower corner, and the other group extends from a right upper corner of the grid frame to a left lower corner. The two groups of grates are crossed. The formed nodes are X-shaped. The formed grids are rhombuses or parallelograms. The structure of the grid is characterized in that: the PSU plastic is used as substrate; the non-ferrous metal is used as an insert, and the lead alloy is used as an outer layer. The structure characteristics cause the grid plate of accumulator to obtain the following advantages: high mechanical strength, small thickness, small electric resistance, etc.
Description
Technical field
The utility model relates to lattice plate of lead-acid accumulator.
Background technology
The employed electrode of traditional lead acid accumulator is a kind ofly to arrange the screen electrode that forms by the alloy lead material by the mode of intersecting anyhow, and the grid of Gou Chenging is a rectangle thus.And adopting the screen of this structure, its mechanical strength is not high.When screen vertically was installed in the battery case, the active material in the screen all was pressed on the horizontal grizzly bar.If battery uses under vibrational state, particularly after the alloy stereotype was by the acid solution corrosion, grizzly bar was easy to fracture.And the crossover node of grizzly bar is " ten " shape, and its intensity is not high yet.Therefore, the battery that has just adopts thickness and the width that strengthens grizzly bar, increases the intensity of grid plate structure.But, do the weight that has but increased battery like this, and grizzly bar takes up space greatlyyer, cause the active material of being filled just few, thereby reduced the electric weight and the electrical property of battery.
The utility model content
At the deficiency that above technology exists, the utility model provides a kind of lattice plate of lead-acid accumulator.
The technical scheme that the utility model is taked is as follows:
A kind of lattice plate of lead-acid accumulator comprises the screen frame, and the grid that the screen frame is provided with grizzly bar and is combined into by grizzly bar is filled with active material in the grid.Grizzly bar is divided into two groups, and extend to the lower right corner in one group of upper left corner from the screen frame, and another group is from the upper right corner inferior horn extension left of screen frame, and two groups of grizzly bars intersect, and the node of formation is " X " shape, and the grid of formation is rhombus or parallelogram.Grizzly bar is done substrate with the PSU plastics, and non-ferrous metal is made inserts, and alloy lead constitutes as skin.
The screen frame is provided with a collection lotus end.
The non-ferrous metal that adopts comprises copper, zinc, aluminium or magnesium.
The beneficial effects of the utility model are: the grizzly bar that is provided with on the screen frame is with the composite construction of PSU plastics as substrate, and be netted intersection between the grizzly bar, the node that forms is " X " shape, the grid that constitutes is rhombus or parallelogram, such design feature makes battery grid plate have advantages such as mechanical strength height, thin thickness, resistance be little.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the cross-sectional configuration schematic diagram of grizzly bar.
Among the figure:
10 screen frames, 101 collection lotus ends,
102 grizzly bars, 103 grids,
104 nodes, 105 substrates,
106 inserts, 107 skins.
Embodiment
Below in conjunction with Fig. 1 and Fig. 2 the utility model is further described:
The structural representation of the present utility model as depicted in figs. 1 and 2 and the structural representation in grizzly bar cross section, lattice plate of lead-acid accumulator among the figure, comprise screen frame 10, screen frame 10 is provided with grizzly bar 102 and by the grid 103 that grizzly bar 102 is combined into, is filled with active material in the grid 103.Grizzly bar 102 is divided into two groups, extend to the lower right corner in one group of upper left corner from screen frame 10, another group is from the upper right corner inferior horn extension left of screen frame 10, two groups of grizzly bars 102 intersect, the node 104 that forms is " X " shape, the grid 103 that constitutes is for erectting rhombus or the parallelogram of placing, and this design feature can change the stressing conditions of grizzly bar 102, thereby has strengthened the intensity of grizzly bar 102.And adopt the mode that is obliquely installed, the collection lotus end 101 that grizzly bar 102 can be provided with to screen frame 10 with the charge transfer that the shortest distance produces active material in the grid 103, electric conductivity is good.Wherein, grizzly bar 102 is done substrate 105 with the PSU plastics, and non-ferrous metal is made inserts 106, the plumbous skin 107 of doing of alloy constitutes (referring to Fig. 2), inserts 106 with outer 107 for contact is connected, skin 107 is that the mode with plating forms, the non-ferrous metal of employing comprises copper, zinc, aluminium or magnesium etc.Adopt such composite construction, can strengthen the intensity and the corrosion resistance of grizzly bar 102.Battery grid plate adopts this structure, its thickness is reduced, and can reduce volume, weight reduction.
Certainly, above embodiment just is explanation rather than restriction the utility model, the above only is preferred embodiment of the present utility model, so all equivalences of being done according to the described method of the utility model patent claim change or modify, is included in the utility model patent claim.
