Abstract
The utility model particularly relates to a grid for the battery. The utility model aims to provide an accumulator grid can reduce the quantity of grid raw materials to guarantee simultaneously that the battery has the same performance, including the frame, be equipped with the rib in the frame, the outer one end of frame is equipped with utmost point ear, frame other end symmetry is equipped with two arc chord angles, the arc chord angle includes the bullnose in the inboard inside radius of frame and the frame outside, the radius r1 of inside radius is 7-8mm, the radius R1 of bullnose is 9-10mm. Because electric current conveying is by last to down, when holding battery life and terminate, only first part active material of polar plate can drop, and now the active material of 20% area is intact, increases the arc chord angle of grid the latter half, can reduce grid the latter half area to reduce quantities such as grid raw materials lead -antimony alloy, plumbous calcium alloy, has still reduced the active material of coating on the grid quantity simultaneously, from the production, greatly reduced material cost.
Description
Technical field
The utility model belongs to storage battery field, is specifically related to a kind of grid for storage battery.
Background technology
Pole plate is lead acid accumulator chief component, the active material of the storage that pole plate has and release electric energy, and inert matter is made paste shape when making and is coated on grid by pole plate often, then generates active material through formation process.As can be seen here, grid mainly plays the effect of carrying active material, because electric current transmission is from top to bottom, when the life of storage battery stops, the upper half part active material of pole plate is just only had to come off, the active material of 20% area is intact below, so the impact of grid the latter half on storage battery is little.The material making grid mainly contains plumbous antimony, lead-calcium alloy, and its consumption is also the principal element of the cost price affecting lead acid accumulator.Reduce the consumption of grid material, greatly will reduce manufacturing cost.
Utility model content
The purpose of this utility model is to provide a kind of battery grid, by the improvement of grid structure, can reduce the consumption of grid raw material, and ensures that storage battery has identical performance simultaneously.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of battery grid, comprise frame, rib is provided with in described frame, the outer one end of described frame is provided with lug, the described frame other end is arranged with two arc chord angles, and described arc chord angle comprises the bull nose outside the filleted corner of scuncheon and frame; The radius r 1 of described filleted corner is 7 ~ 8mm, and the radius R 1 of described bull nose is 9 ~ 10mm.
Preferred: the radius r 1 of described filleted corner is 8mm, the radius R 1 of described bull nose is 10mm.
Preferred: the radius r 1 of described filleted corner is 7mm, the radius R 1 of described bull nose is 9mm.
Preferred: on described frame, lug place end is also provided with symmetrical arc chord angle, described arc chord angle comprises the bull nose outside the filleted corner of scuncheon and frame; The radius r 2 of described filleted corner is 2.5mm, and the radius R 2 of described bull nose is 3mm.
The utility model has following beneficial effect: lug is positioned at the first half of grid, on grid, one end that is relative and lug is then positioned at the latter half of grid, from top to bottom in electric current transmission, when the life of storage battery stops, the upper half part active material of pole plate is just only had to come off, the active material of 20% area is intact below, increase the arc chord angle of grid the latter half, the area of grid the latter half can be reduced, thus reduce grid raw material lead-antimony alloy, the consumption of lead-calcium alloy etc., also reduce the consumption of the active material be coated on grid simultaneously, from production, greatly reduce cost of material.In prior art, the arc chord angle radius of the latter half is generally 2 ~ 4mm, experimentally proves in the utility model, expands the arc chord angle of the latter half to zone of reasonableness, can not have influence on the original performance of storage battery.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment 1
As shown in Figure 1, a kind of battery grid, comprises frame 1, rib is provided with in described frame 1, described outer one end of frame 1 is provided with lug, and described frame 1 other end is arranged with two arc chord angles, and described arc chord angle comprises the filleted corner 2 inside frame 1 and the bull nose 3 outside frame 1; The radius r 1 of described filleted corner 2 is 7 ~ 8mm, and the radius R 1 of described bull nose 3 is 9 ~ 10mm.
Preferably, the radius r 1 of described filleted corner 3 is 8mm, and the radius R 1 of described bull nose 3 is 10mm.On described frame 1, lug place end is also provided with symmetrical arc chord angle, and described arc chord angle comprises the bull nose 5 outside the filleted corner 4 of scuncheon and frame; The radius r 2 of described filleted corner 4 is 2.5mm, and the radius R 2 of described bull nose 5 is 3mm.
The grid in technique scheme is utilized to make the storage battery that rated capacity is 5Ah, compared with the storage battery being 5Ah with the rated capacity utilizing grid of the prior art to make, property indices has almost no change, reach the improvement by grid structure, the consumption of grid raw material can be reduced, pole plate cover is heavy is reduced to 1000g by 1100g, and ensures that storage battery has the object of identical performance simultaneously, as shown in the table:
Embodiment 2
Be that the radius r 1 of described filleted corner 2 is 7mm with embodiment 1 difference, the radius R 1 of described bull nose 3 is 9mm.
The grid in technique scheme is utilized to make the storage battery that rated capacity is 5Ah, compared with the storage battery being 5Ah with the rated capacity utilizing grid of the prior art to make, property indices has almost no change, reach the improvement by grid structure, the consumption of grid raw material can be reduced, pole plate cover is heavy is reduced to 1030g by 1100g, and ensures that storage battery has the object of identical performance simultaneously, as shown in the table:
