Abstract
The utility model relates to a storage battery plate grid. The storage battery plate grid comprises a frame and a tab as well as longitudinal ribs and transverse ribs, wherein the frame is enclosed by frame ribs; the tab is fixed on one frame rib; the longitudinal ribs and the transverse ribs are arranged in the frame in a crossed manner; the transverse ribs are parallel to the frame rib fixed with the tab; and the summation of cross section areas at the centers of the longitudinal ribs is larger than that of cross section areas at the centers of the transverse ribs. According to the utility model, as the summation of the cross section areas at the centers of the longitudinal ribs is larger than that of the cross section areas at the centers of the transverse ribs, the storage battery plate grid provided by the utility model has the advantages of strong conductivity, comparatively small current loss, simple structure and strong applicability.
Description
Technical field
The utility model relates to storage battery and makes field, particularly a kind of battery grid.
Background technology
The critical piece of storage battery is a pole plate, and mostly pole plate is paste spread type, and promptly covering is smeared active material and become pole plate on grid, and grid mainly works to support active material and conduction current.Grid is to be made up of horizontal rib and lengthways of rod crisscross in certain thickness frame rib, lug and the frame.
The existing storage battery grid adopts the structure that horizontal rib is many, lengthways of rod is few mostly, and the cross-sectional area of lengthways of rod does not often have the cross-sectional area of horizontal rib big; Electric current from away from lug one laterally closer lug one effluent to, the electric current that lengthways of rod bears is bigger than horizontal rib, this structure often makes the elongated and current density of the flow path of electric current become big, the causes current loss increases; Rib generally all adopts the consistent design of thickness everywhere, because electric current compiles to the top from the pole plate bottom, current step increases, and thickness is consistent about the rib, causes internal resistance to increase, and the grid conductive capability weakens; Simultaneously the gap between each transverse rod strip thickness and transverse rod strip and the parallel frame rib is consistent, causes CURRENT DISTRIBUTION inhomogeneous, and active material utilization is not high, and simultaneously, electrolyte is prone to layering, thereby makes the battery premature failure.
The utility model content
The utility model provides a kind of battery grid, has solved the bigger problem of current loss in the storage battery that causes because of the grid unreasonable structure in the prior art.
A kind of battery grid; Comprise the frame that surrounds by the frame rib, be fixed therein a lug and staggered on the frame rib and be located at lengthways of rod and horizontal rib in the frame; Described horizontal rib is parallel with the frame muscle that is fixed with lug, and the cross-sectional area summation at said lengthways of rod center is greater than the cross-sectional area summation at said horizontal rib center.
The cross-sectional area of every lengthways of rod is by reducing gradually to the other end near lug one end; Every the horizontal bar sliver transvers section is long-pending equal everywhere; The sectional area of single horizontal rib to meet the direction that electric current compiles, reduces internal resistance from successively decreasing near lug one side direction opposite side.
Lengthways of rod and frame rib in parallel constitute first group of rib; Laterally rib and frame rib in parallel constitute second group of rib; The spacing of first group of rib is increased progressively to both sides by the centre, and the spacing of second group of rib makes CURRENT DISTRIBUTION even by increasing progressively near lug one side direction opposite side; Improve the utilance of active material, suppress the layering of electrolyte.
The described frame rib outside that is connected with lug is provided with strengthens the shirt rim, and the thickness of said reinforcement shirt rim is increased to the lug place by two ends gradually, improves the current flux of lug junction, reduces the internal resistance of grid.
The utility model since the cross-sectional area summation at lengthways of rod center greater than the horizontal cross-sectional area summation at rib center, the conductive capability of grid is strong and current loss is relatively little, and simple in structure, applicability is strong.
Description of drawings
Fig. 1 is the structural representation of the utility model battery grid.
Embodiment
A kind of battery grid as shown in Figure 1 comprises the frame 1 that surrounded by the frame rib, is fixed therein a lug 2 on the frame rib, and frame 1 structure that roughly is rectangle is provided with crisscross lengthways of rod 3～7 and horizontal rib 8～13 in the frame.
Lengthways of rod 3～7 is a vertebral body structure; Its sectional area successively decreases to the other end from the end near lug 2; And the homogeneous structural of horizontal rib 8～13; Sectional area everywhere equates, but the sectional area of the horizontal rib that distributes near lug is greater than the sectional area of the horizontal rib that distributes away from lug, and promptly the sectional area of single horizontal rib is from successively decreasing near lug one side direction opposite side.More main, the cross-sectional area summation at lengthways of rod 3～7 centers is greater than the cross-sectional area summation at horizontal rib 8～13 centers.This structure meets the binding mode of electric current, can reduce the grid internal resistance, reduces current loss.
Lengthways of rod 3～7 is parallel with vertical frame rib, constitutes first group of rib, and laterally rib 8～13 is parallel with horizontal frame rib, constitutes second group of rib.The spacing of first group of rib is increased progressively toward both sides by middle, and the spacing of second group of rib is by increasing progressively near lug 2 one side direction opposite sides, and this structure can make CURRENT DISTRIBUTION even, improves the utilance of active material, suppresses electrolyte stratification.
In addition, the frame rib outside that is connected with lug 2 is provided with strengthens shirt rim 14, and the thickness of strengthening shirt rim 14 is increased to lug 2 places by two ends gradually, to increase the current flux at lug place, reduces the grid internal resistance.
In the present embodiment and since electric current from away from an end of lug near an end of lug longitudinally rib increase progressively, so the transversal sectional area of lengthways of rod according to this direction increase progressively with the change in current size and match.The distribution density of lengthways of rod meets the characteristics that the electric current centre is close, two is little; Laterally the distribution density of rib meets the up big and down small characteristics of electric current, has finally reduced the grid internal resistance, has increased the equal and property of CURRENT DISTRIBUTION, has improved the utilance of active material, has prolonged battery life.
