Abstract
The utility model discloses a gridlead-acid battery grid of good conductance performance, which comprises a upper frame, a lower frame, a left frame and a right frame. The upper frame is provided with a tab as the current influx area. A plurality of first ribs and second ribs are arranged inside the quadrangle constructed by the above four frames. The quadrangle is divided into a plurality of through holes by the first ribs and the second ribs. The second ribs are arranged radially. The upper frame has 2-3 times the cross-sectional area of the lower frame.
Description
Technical field
The utility model relates to the battery technology field, specifically is a kind of grid of lead acid accumulator.
Background technology
The grid that a kind of lead acid accumulator is arranged at present, it comprises upper side frame, lower frame, left frame and left frame, described upper side frame is provided with the lug as the electric current pooling zone, be distributed with a plurality of first ribs and second rib in the quadrangle that constitutes by above-mentioned four frames, described first rib and second rib are partitioned into a plurality of through holes with described quadrangle, this through hole is used to adhere to active material, and the electric current that active material produces can flow to upper side frame by described second rib, flows to lug by upper side frame then.
As seen from the above analysis, described second rib and upper side frame are as the path of current direction lug, for the path that makes the current direction upper side frame short as far as possible (the short as far as possible purpose of path is in order to reduce the loss of electric current in the process of circulation), structure commonly used at present is that second rib is radially distributed, promptly second rib points to lug as far as possible, and the structure that upper side frame gathers as electric current is very crucial, but in the present structural design, upper side frame only considers that satisfying mechanical strength gets final product, for simplicity, it is just passable that the cross-sectional area of described upper side frame and lower frame equates, both are as broad as long, therefore, the possibility that loss was bigger when electric current was flowed through upper side frame increases greatly, and then has reduced the electric conductivity of the grid of described lead acid accumulator.
The utility model content
The technical problems to be solved in the utility model is that a kind of grid of the lead acid accumulator that conducts electricity very well is provided.
The technical solution of the utility model is, the grid of the utility model lead acid accumulator, it comprises upper side frame, lower frame, left frame and left frame, described upper side frame is provided with the lug as the electric current pooling zone, be distributed with a plurality of first ribs and second rib in the quadrangle that constitutes by above-mentioned four frames, described first rib and second rib are partitioned into a plurality of through holes with described quadrangle, and described second rib is radial, and the cross-sectional area of described upper side frame is 2～3 times of cross-sectional area of lower frame.
After adopting said structure, the utility model compared with prior art, have the following advantages: because the cross-sectional area of described upper side frame is 2～3 times of cross-sectional area of lower frame, the cross-sectional area of lower frame is chosen as long as consider mechanical strength, come to determine the cross-sectional area of upper side frame as a reference with the cross-sectional area of lower frame, the increase of the sectional area of upper side frame has guaranteed its electric conductivity on the one hand, reduced the loss that electric current flows through upper side frame, on the other hand, simplified design, after reality adopts said structure, through experiment, loss was less when electric current was flowed through upper side frame, and the grid electric conductivity of lead acid accumulator is reliable, so the utlity model has the advantage that conducts electricity very well.
As improvement, the radiation initial point of described second rib is positioned on the left-right symmetric line of lug, the span of the spacing between the intersection point that the extended line of described adjacent second rib or its extended line and lower frame or lower frame intersects is 16～20mm, the span of the spacing between described adjacent first rib is 5～7mm, like this, cross-sectional area at the through hole of dividing away from the zone of lug will compare rationally, not too large, and then guaranteed that active material adhesion-tight degree meets or exceeds design objective, more helps the raising of the utility model performance.
As further improvement, transition second rib is set in described second rib, second rib after this transition second rib is all parallel with described transition second rib, like this, the distribution of second rib is more reasonable, be that transition second rib second rib before is the radial of focus type, second rib after transition second rib is parallel to each other, and above-mentioned improvement more helps the raising of the utility model performance.
