Abstract

The utility model relates to a tube type positive plate for a lead-acid battery, which comprises an alloy slab lattice, a non-metallic casing tube and active substances. The utility model is characterized in that the contacting positions of an upper and a lower ports of the non-metallic casing tube and the alloy slab lattice are respectively provided with a plastic sealing top with a through hole and a plastic sealing bottom with a blind hole. The cross-section of a current conducting rib in the alloy slab lattice is rectangular, and a metal cold-stamping piece is adopted by the alloy slab lattice. The utility model has the advantages of alloy material economization, light weight, simple machining and high yield. The performance of the utility model is enhanced, and service life is prolonged. Compared with the original positive plate of directly using a bulged part of the alloy slab lattice for plugging the non-metallic casing tube and adopting a slab lattice of a pouring piece, the utility model has obvious superiority.

Description

Tube-sbaped positive plate

The utility model relates to a kind of polar plate of lead acid storage battery, particularly tube-sbaped positive plate.

Anode plate for lead acid accumulator has two kinds of paste spread type positive plate and tubular type positive plates.Tubular type positive plate in the past is made up of grid, non-metallic casing, back cover, active material, the upper port of non-metallic casing, directly contact with grid, generally the shoulder by grid partly blocks, back cover is also made by the grid same type of material usually, so both alloy materials of using high price have increased weight again more, and plugging effect is also bad.The cross section of conduction rib is generally circle or ellipse in the grid, and grid is whole, and often rate of finished products is low in order to water foundry goods, and process velocity is slow, and cost height, crystal grain are not fine and close, poor corrosion resistance, and conductive resistance is big, and pole plate and the battery of making are short useful life.

The purpose of this utility model is to overcome weak point of the prior art, provide a kind of in light weight, cost is low, performance good, the tube-sbaped positive plate of long service life.

The technical solution of the utility model is: tube-sbaped positive plate comprises alloy grid, non-metallic casing, active material, improvements are that the plastics that are provided with the band through hole between the upper port of non-metallic casing and the grid bind, be provided with the plastics back cover of band blind hole between lower port and the grid, the cross section of conduction rib is a rectangle in the grid.

Above-mentioned plastics bind, the plastics back cover is split type or many combineds of single-piece; Alloy grid is a metal cool-press spare; Non-metallic casing can be single split type or many combineds, and its cross section can be circle, ellipse, also can be rectangle.

Adopt technique scheme, plastics bind, the plastics back cover owing to be provided with, and replace original alloy shutoff, both weight reductions, reduce cost, and improve plugging effect again; The square-section of conduction rib makes alloy grid adopt cold-stamped part to become possibility in the grid, can avoid former many disadvantages of watering foundry goods like this, improves the pole plate performance, prolongs the useful life of pole plate and battery.

Further specify the utility model below in conjunction with drawings and Examples.

Fig. 2 is the place's structural representation that binds;

Fig. 3 is a back cover place structural representation;

Fig. 4 is the plastics combined structural representation that binds;

Fig. 5 is a plastics back cover combined structural representation.

As figure, cross section is to fill up active material 3 between the conduction rib of rectangle and the non-metallic casing 4 in the alloy grid 1, the upper and lower port place of non-metallic casing is provided with plastics respectively and binds 2 and plastics back cover 5, and grid adopts the cold-reduced sheet of lead alloy material to make through cold stamping.Plastics bind and the plastics back cover is many combineds.
