Mouthful, reinforcing plate is equipped in the notch.It is arranged in battery trench bottom in the utility model and is trapped by the powder that glass is interwoven
Block is directly entered in powder trapping hole in the block after being fallen from the active material powder on pole plate and carries out trapping thus and pole plate
Component separates, and avoids the active material powder fallen from being accumulated in pole plate group and causes short circuit, even if in addition lead-acid accumulator occurs
It is inverted, there will not be a large amount of powders and poured out from powder trapping block, isolation effect is good, and powder trapping block is in accumulator plastic housing
It is directly put into battery case after demoulding, assembly is very convenient, and limiting bracket avoids to the insertion depth of control pole board group
Pole plate group, which contacts after being inserted into battery case with powder trapping block, makes powder trapping block compressive deformation, influences powder trapping effect；Add
Strong plate improves its anti-collision energy to improve the structural strength of four corners of housing bottom.
Preferably, the powder trapping block is bilayer, the hole for being located at the powder trapping block on upper layer is more than positioned at lower layer
Powder trapping block hole.Powder trapping block is bilayer, and the powder trapping block hole on upper layer is larger, is rapidly entered convenient for powder
In order to avoid powder is blocked, accumulated in powder trapping block, the powder trapping block hole of lower layer is smaller to trap powder completely, avoids it again
It is dropped out from powder trapping block.
Preferably, the limiting bracket include profile limitting casing compatible with battery case inner wall and be located at limitting casing bottom
Stabilizer blade at four, portion corner location, the limitting casing are located at powder trapping block upper surface and are crimped with powder trapping block.Due to limit
The presence of position frame and stabilizer blade so that pole plate group is inserted into battery case and can be contacted with limitting casing after certain depth, in the limit of limitting casing
Under the effect of position, the lower end of pole plate group will not be pressed onto powder trapping block to avoid powder trapping block from deforming.
Preferably, the limitting casing is homogeneity integral structure with stabilizer blade.
Preferably, be bonded between the reinforcing plate and shell.
Preferably, the reinforcing plate is metal material.
Therefore, the utility model has the advantages that：
(1) the powder trapping block being interwoven by glass is set in battery trench bottom, from the active material powder on pole plate
It is directly entered after falling in powder trapping hole in the block and carries out trapping to be separated with pole plate component, avoid the active matter fallen
Matter powder is accumulated in pole plate group causes short circuit, even if in addition lead-acid accumulator is inverted, there will not be a large amount of powders from powder
It is poured out in material trapping block, isolation effect is good, and powder trapping block is directly put into battery case i.e. after accumulator plastic housing demoulding
Can, assembly is very convenient；
