Abstract

The invention discloses a maintenance-free battery for communication, which comprises a battery cover (1), a battery shell (2) and a partition plate (6), wherein pole plates (6) in each unit cell of the battery shell are connected by bus bars (8), the unit cell are connected by butt welding pieces (9), two bus bars (8) at one end of the battery are connected with post terminals (5), the butt welding pieces (9) are subjected to wall-through welding, the battery cover (1) and the battery shell (2) are sealed by heat to form the battery integrally, the pole plates (6) are thin pole plates with pure lead grids, the pole groups are connected by wall-through welding, and the battery cover (1) and the battery shell (2) made of an ABS (acrylonitrile butadiene styrene) material are sealed by heat. The maintenance-free lead-acid battery provided by the invention is designed for the communication industry, and solves the defects of poor large-current discharge, unstable quality, high cost, poor tightness, short service life, high self-discharge rate and poor charge acceptance capability to a great extent when the common industrial battery is used in the communication industry.

Description

A kind of communication maintenance-free lead accumulator

Technical field

The present invention relates to maintenance-free lead accumulator, particularly a kind of communication maintenance-free lead accumulator.

Background technology

Communication is the nervous system of current social life, does not generally allow to interrupt.Therefore, in the power supply system for communications, multiple-connected battery all except that other direct current supplys.The little electric current floating charge of accumulators in case the normal power supply system breaks down, then uses storage battery power supply under the normal condition, keeps and continues communication, treat the stand-by generator starting operation after, storage battery has just been finished emergent mission.

The communication maintenance-free lead accumulator of present most of manufacturer production, internal structure is with common industrial battery indistinction, and the general electrode thickness that uses is thicker, terminal, weldment, bus-bar is adopted manual welding, to being to stride bridge welding between the weldment, between the cap glue envelope.The battery of this kind structure has following some problem to exist: 1, the thick meeting of pole plate reduces the utilance of active material, is not suitable for heavy-current discharge; 2, manual welding quality instability, hidden danger are big; 3, it is big to stride the bridge welding consumption of lead, the cost height, and the solder joint place is prone to problem; 4, cap adopts the glue envelope, and fluid sealant is subjected to phenomenons such as going bad can appear in the influence of environment, leaks air easily and leaks sour phenomenon, causes contaminated environment and damage equipment; 5, grid has impurity, corrosion easily, and the life-span is short; 6, charge acceptance is poor.

Summary of the invention

The objective of the invention is to: a kind of communication maintenance-free lead-acid battery is provided, solves to a great extent that the general industry battery is used in that the heavy-current discharge of communications industry institute output is poor, quality instability, cost height, sealing is poor, the life-span is short, self discharge is big, the drawback of charge acceptance difference.

Technical solution of the present invention is: adopt novel pure stereotype grid to approach pole plate, the thin pole plate of pure stereotype grid is one of at present very advanced pole plate, especially more outstanding aspect the active material utilization of battery, charge acceptance, battery life, so select for use the pole plate of high-quality to improve problems such as the common batteries heavy-current discharge performance is poor, the life-span short, self discharge is big, charge acceptance difference; To between the common cell negative terminal weldment welding manner be changed into through-wall welding by striding bridge welding, reduce internal resistance, extra power consumption when reducing battery charging and discharging, and save the plumbous amount of consumption and reduce cost; Change heat-sealing into by original glue envelope between the cap, avoid fluid sealant, and make battery gas leakage or leakage is sour, battery failure owing to the influence that is subjected to environment go bad;

The invention has the advantages that: 1, electrode thickness is ultra-thin, has increased the active material response area to a great extent, has improved active material utilization, thereby has solved the heavy-current discharge problem; 2, single lattice connected mode is the through-wall welding welding, has reduced consumption of lead, has reduced cost; 3, the cap sealing means is heat-sealing, the heat-sealing good seal performance, and weld is not subjected to the influence of environment, indeformable never degenerating, thus avoid the gas leakage and the phenomenon of splitting; 4, the life-span long, can use 8 years, common is 4 years; 5, can carry out quick charge, can charge into 95% electric weight in 4 hours, the common batteries charging interval is generally more than 6 hours.

Among the figure: 1 dough sheet, 2 safety valves, 3 polarity marks, 4 battery covers; 5, terminal, 6, pole plate, 7, dividing plate, 8, bus-bar, 9, to weldment, 10, battery case.

Embodiment

As shown in Figure 1, 2, 3, this storage battery comprises dough sheet 1, safety valve 2 and polarity mark 3 are installed above the battery cover 4, in battery case 10 single lattice pole plate 6 and dividing plate 7 are housed, pole plate 6 has bus-bar 8 to connect, have pair weldment 9 to connect between single lattice, wherein two bus-bars 8 of battery one end connect pole terminal 5; During assembling: at first, will be to weldment 9 through-wall weldings; Once more, battery cover 4 and battery case 10 seal; The 3rd, install safety valve 2 and polarity mark 3 on the battery cover 4; The 4th, with glue dough sheet 1 is enclosed on the battery cover 4; The 5th, add electrolyte in the battery, whole formation storage battery.

Wherein, what pole plate 6 used is the thin pole plate of pure stereotype grid, connects by through-wall welding between the utmost point group; Seal by heat-sealable way between the battery cover 1 of ABS material and the battery case 2.

During use, connect the connecting line of electrical appliance at the positive and negative terminal of battery, connect the connecting line of charger behind the battery discharge at positive and negative terminal, battery is charged, charge and discharge process can carry out repeatedly.

Claims

1. communication maintenance-free lead accumulator is characterized in that: wherein, what pole plate (6) used is the thin pole plate of pure stereotype grid, connects by through-wall welding between the utmost point group, seals by heat-sealable way between battery cover of ABS material (1) and the battery case (2).
