During use, directly welded by lug between the positive and negative grid utilizing the present invention to make and just connected together, compare with present lead acid accumulator, eliminate this component of bus-bar, thus consumption of lead can be saved in a large number, pole plate resistance can be reduced simultaneously, improve the power of storage battery.
As preferably, lug is the lug that perpendicular rib extends.
As preferably, each perpendicular rib extends lug respectively.
As preferably, lug is the lug for directly welding with the lug on opposite polarity grid.
As preferably, the spacing between perpendicular rib is less than the spacing between transverse rod strip.Preferred further, the spacing between transverse rod strip is 1.5 times to 2.5 times of the spacing between perpendicular rib.Existing lead acid accumulator, the gravity casting spacing of erecting between rib is greater than the spacing between transverse rod strip, but the few of help of the conduction of transverse rod strip to pole plate.The present invention, under ensureing that the spacing between perpendicular rib is less than the prerequisite of the spacing between transverse rod strip, spacing between perpendicular rib is generally 7 millimeters to 12 millimeters, spacing between transverse rod strip is then 10 millimeters to 18 millimeters, grid can directly be cast in perpendicular rib direction, it is just fewer that the quantity of transverse rod strip retains, and the object of reserve part transverse rod strip is the distortion in order to reduce perpendicular rib.This preferred version, is conducive to the effective rate of utilization improving material, improves the power of storage battery.
As preferably, the outer side edges of outermost two perpendicular ribs is respectively equipped with support ear.Preferred further, the number of the support ear that the outer side edges of outermost two perpendicular ribs is provided with is two, wherein away from support ear distance outermost two transverse rod strips of lug center line between distance be not equal to distance between the center line of support ear distance outermost two transverse rod strips of lug.Here, the center line of described outermost two transverse rod strips, refer to parallel with outermost two transverse rod strips and to the equidistant straight line of outermost two transverse rod strips, namely, the support ear away from lug and the support ear near lug with this center line for axis becomes asymmetric distribution.When positive and negative grid oppositely place by overlap, the spacing between the support ear on positive and negative grid is not less than 10mm.This preferred version, support ear of the present invention is conducive to the accurate location utilizing pole plate of the present invention, prevents pole plate to be partial to the side of pole group, thus is conducive to the reliability and the serviceability that improve lead acid accumulator.In addition during the reverse lamination of positive and negative pole plate, can ensure that the support ear of positive and negative pole plate is dislocation, thus be short-circuited by support ear between positive and negative pole plate when can prevent positive and negative pole plate lamination.
As preferably, be connected with the perpendicular rib fillet of outermost two apart from lug transverse rod strip farthest.Preferred further, the radius of corner that distance lug transverse rod strip is farthest connected with the perpendicular rib fillet of outermost two is more than or equal to 3 millimeters and is less than or equal to 10 millimeters.This preferred version, is conducive to the reliability improving grid.
As preferably, the cross section of perpendicular rib and transverse rod strip is rectangle, chamfering rectangle, round rectangle, rhombus or ellipse, and support ear is rectangular, circular arc, triangle or trapezoidal.
In sum, the beneficial effect that the present invention brings is: greatly can reduce consumption of lead when manufacturing lead acid accumulator and pole plate resistance, improve the power of storage battery simultaneously.
