Active material utilization is higher in the lead plaster of position, and active material can discharge the corrosive substances such as sulfuric acid at work, is easy corruption
Vertical bar item 4 and transverse rod strip 3 are lost, in practical applications, often the closer vertical bar item 4 of appearance distance tab 2 and 3 end of transverse rod strip be
Be corroded fracture, and also intact apart from the farther away vertical bar item 4 of tab 2 and transverse rod strip 3, and entire current-carrying plate each section utilizes
Unevenness, service life is shorter, results in waste of resources.
Summary of the invention
Goal of the invention: aiming at the problems existing in the prior art, the present invention provides a kind of battery current-carrying plate, can be effective
The utilization rate of the electronics on current-carrying plate in each section lead plaster in active material is balanced, effectively extends the current-carrying plate service life.
Technical solution: the present invention provides a kind of battery current-carrying plate, including frame, tab, several transverse rod strips and several
Vertical bar item, the tab are located at the frame one side edge, and the conducting that intersects of each transverse rod strip and each vertical bar item is set
Set in the scuncheon, several vertical bar items that at least a main vertical bar item is located along the same line with the tab,
Remaining each vertical bar item is successively arranged to two sides using the main vertical bar item as baseline；The transverse rod strip dislocation of every vertical bar two sides
Setting, each transverse rod strip be it is cone-shaped, one end close to the main vertical bar item is thicker, and from by side proximad far from the tab
To the spacing between the transverse rod strip is gradually reduced two-by-two, and the area of each transverse rod strip successively successively decreases.
Preferably, each vertical bar item is cone-shaped, and one end close to the tab is thicker.
Preferably, from by the direction proximad far from the tab, the spacing between the vertical bar item is gradually reduced two-by-two.
Preferably, from by the direction proximad far from the main vertical bar item, the area of each vertical bar item successively successively decreases.
The utility model has the advantages that compared with prior art, on the one hand, each transverse rod strip dislocation of the two sides of each vertical bar item is set in the present invention
It sets, the conductive channel between transverse rod strip each in this way and vertical bar item is distributed relatively uniform in entire frame, smears on current-carrying plate
After lead plaster, the electronics in lead plaster in active material can be moved on each transverse rod strip and each vertical bar item, be equivalent on current-carrying plate
Electronics overall distribution is more uniform, and then electronics tends to be moved to along each rib and be located on collinear main vertical bar item with tab
(because linear distance is most short, electronics can also select to be moved to destination apart from shortest route --- on tab), final electronics
Tab position is transmitted to by main vertical bar item to be utilized by tab.So for current-carrying plate in compared with the existing technology, in the present invention
Current-carrying plate in each section active material electronics utilization rate relative equilibrium, can reduce to a certain extent apart from tab compared with
The transverse rod strip and vertical bar item of proximal end improve load since the active material utilization of this part is larger and the possibility for the fracture that is corroded
The service life of flowing plate；
On the other hand, each vertical bar item is cone-shaped in the present invention, and one end of close tab is thicker, and each transverse rod strip is also point
Cone cell, and it is thicker close to one end of main vertical bar item, electronics is moved along each transverse rod strip and vertical bar item to be pooled to close to the position of tab
When, due to relatively thick close to vertical bar one end of tab, thicker close to transverse rod strip one end of main vertical bar item, relative to thinner separate
Vertical bar one end of tab, thinner separate main vertical bar item transverse rod strip one end, it is smaller compared with the resistance of butt end (only consider material face
In the case where product), relatively small compared with the voltage of butt end in the case where electric current is equal, this makes it possible to relative reductions to lean on proximal pole
The utilization rate of active material in the lead plaster of ear position promotes the utilization rate of active material in the lead plaster far from tab position, thus
Achieve the purpose that equilibrium using each section vertical bar item and transverse rod strip on entire current-carrying plate, promotes the service life of entire current-carrying plate,
Economize on resources the energy；
In another aspect, from by proximad far from the direction of tab in the present invention, two-by-two transverse rod strip, two-by-two between vertical bar item between
Away from being gradually reduced, in this way, after smearing lead plaster on current-carrying plate, one end far from tab is made of each transverse rod strip and each vertical bar item
Square it is just smaller, the electronics in lesser square in lead plaster in active material can be moved to each transverse rod strip and each perpendicular quickly
On rib (because square is smaller, moving displacement is smaller), then electronics is moved to tab position by tab benefit along each rib
With；And apart from tab closer current-carrying plate one end, each transverse rod strip and the square that each vertical bar item forms are just larger, in biggish square
Electronics in lead plaster in active material is moved to institute on each transverse rod strip and each vertical bar item for compared with the electronics in small cube
The time needed is longer (because square is larger, moving displacement is larger), balances so the present invention is equivalent to apart from tab
Nearer end and utilization rate compared with electronics in active material on the current-carrying plate of distal end, compared with the existing technology in current-carrying plate for, this
On current-carrying plate in invention in each section active material electronics utilization rate relative equilibrium, effectively avoid apart from tab nearer end
Transverse rod strip and vertical bar item due to the active material utilization of this part is larger and the fracture that is corroded, effectively promote the longevity of current-carrying plate
Life；
Finally, the present invention is from by the direction proximad far from main vertical bar item, the area of each vertical bar item is gradually reduced；From by proximad
One end far from tab, the area of each transverse rod strip are gradually reduced；The biggish vertical bar item of area and smaller (the only consideration of transverse rod strip resistance
In the case where material area), in the case where electric current is equal, the voltage on the biggish vertical bar item of area and transverse rod strip is relatively
Small, this makes it possible to the utilization rates of relative reduction active material in the lead plaster of tab position, are promoted far from tab position
The utilization rate of active material in lead plaster, to reach the balanced mesh using each section vertical bar item and transverse rod strip on entire current-carrying plate
, the service life of entire current-carrying plate is promoted, economize on resources the energy.
