The bus-bar is directly molded through a cast-weld craft, lead components are eliminated, higher counter electrode plates can be used in the same storage battery shell, and the charge capacity of the storage battery is improved. The cast-weld craft utilized by the valve control sealing type lead-acid battery gap bridge connecting structure can be achieved through machine automation, various possible unstable factors caused by manual operation can be avoided, and meanwhile the once formed valve control sealing type lead-acid battery gap bridge connecting structure saves production time and improves production efficiency of the storage battery.

Description

A kind of valve-regulated sealed lead-acid batteries bridge gap connection structure

Technical field

The utility model relates to the Lead-acid Battery Technology field, is specifically related to the bridge gap connection structure of valve-regulated sealed lead-acid batteries.

Background technology

Along with the development in accumulator product market, market is more and more higher to the requirement of storage battery.Widely used storage battery is valve-regulated sealed lead-acid batteries in the market.The monomer rated voltage of valve-regulated sealed lead-acid batteries is 2V, after a plurality of monomer series-connected connections, just can form higher voltage, satisfies different instructions for uses.

Present valve-regulated sealed lead-acid batteries, most modes that adopt plumbous part to connect, as depicted in figs. 1 and 2, the positive pole ear 111 of each utmost point group monomer and negative lug 112 are connected respectively to positive bus 131 and negative bus 132 by plumbous part 12, and positive bus 131 is connected by gap bridge 133 with negative bus 132.There is following problem in this connected mode:

1) same enclosure can not be accomplished more high power capacity

Because used plumbous part, occupied the Partial Height of storage battery, cause pole plate height-limited, therefore charge capacity also is restricted.

2) heavy-current discharge performance is good not

Because used plumbous part, being in discharge during operating mode, can produce voltage drop, the guiding discharge time shorten affects the overall performance of storage battery.

3) production efficiency is low

Used the storage battery of plumbous part plumbous part scorification need to be connected when producing, when particularly many lattice connect, all wanted scorification to connect between every lattice, cost is many man-hour, and production efficiency is low.

The utility model content

The purpose of this utility model is to make the storage battery of same size to obtain larger battery capacity, improves the storage battery heavy-current discharge performance, also improves simultaneously the production efficiency of storage battery.

For achieving the above object, the utility model provides a kind of technical scheme:

A kind of valve-regulated sealed lead-acid batteries syndeton comprises utmost point group and bus-bar.Described bus-bar is copper bus-bar.Bus-bar is divided into positive bus and negative bus, and positive bus is connected by passing a bridge with negative bus; Positive bus, negative bus are integral with positive pole ear, the negative lug cast welding of each utmost point group monomer respectively.

Bus-bar is cast welding moulding " H " shape structure or " U " shape structure.

The positive bus of bus-bar both sides, negative bus are identical with gap bridge thickness, and three's end face is in the same level face.

The utility model beneficial effect compared with prior art is:

(1) the utility model uses cast welding moulding copper bus-bar, has omitted plumbous part, being under the discharge operating mode, has effectively reduced voltage drop, has improved the overall performance of storage battery.

(2) the utility model with the bus-bar straight forming between the utmost point group, has omitted plumbous part by cast welding technique, can use highly higher pole plate in same battery cell case, thereby has promoted the charge capacity of storage battery.

(3) the cast welding technique of the utility model use can realize by the machine automation, the various destabilizing factors of having avoided manual operation to occur, and the production time has been saved in simultaneously one-shot forming, has improved the production efficiency of storage battery.

Embodiment

In order to more fully understand technology contents of the present utility model, below in conjunction with specific embodiment the technical solution of the utility model is further introduced and explanation.

Present embodiment is a kind of valve-regulated sealed lead-acid batteries syndeton, as shown in Figure 3, comprises utmost point group 21 and bus-bar 22.Bus-bar 22 is copper bus-bar, is integral with positive pole ear 211 and negative lug 212 cast weldings, directly omits plumbous part, and because the resistivity of copper is low, the voltage drop ratio that produces during discharge is little when using plumbous part, and whole syndeton is simplified, and overall performance improves.

As shown in Figure 4, bus-bar 22 is divided into positive bus 221 and negative bus 222 in the present embodiment, and positive bus 221 is connected by gap bridge 223 with negative bus 222.Positive bus 221 is integral with positive pole ear 211 cast weldings, and negative bus 222 then is integral with negative lug 212 cast weldings.Use cast welding technique to realize the mechanical automation operation, the various uncertain factors of having avoided manual operation to bring have improved the production efficiency of storage battery, have guaranteed the stability of product quality.

Bus-bar is cast welding moulding " H " shape structure.

The positive bus 221 of bus-bar 22 two side ends, negative bus 222 are identical with 223 thickness of passing a bridge, and three's end face is in the same level face, have saved the volume of storage battery.

The above only further specifies technology contents of the present utility model with embodiment; so that the reader is more readily understood; but do not represent execution mode of the present utility model and only limit to this, any technology of doing according to the utility model is extended or recreation, all is subjected to protection of the present utility model.
