Description

Battery post or to weldment structure and the method that connects with bus-bar

Technical field

The present invention relates to lead acid accumulator, particularly the conductive attachment in the battery.

Background technology

There is a kind of situation in the lead acid accumulator of prior art: because inside battery is full of acid mist, will produce corrosion to electrode in a short period of time, form pore.Acid ion in the storage battery is along constantly upwards corrosion of pore, and " the climbing acid " that has occurred it has often been said is seepage acid solution phenomenon.Therefore must the pole of lead acid accumulator be sealed.So the battery middle cover time leaves position to the pole sealing to seal in design.

Also there is another kind of situation:, need strict the separation between these monomers owing to 4V, 6V, 8V, 10V, batteries such as 12V, 24V are the monomers that comprises a plurality of series connection.Therefore must weldment be sealed to lead acid accumulator.So the battery middle cover design the time leave to the position of weldment sealing to seal.

But when manufacturing and designing the storage battery of different size model, wish that certain parts are applicable to the battery of multiple model, so that reduce cost.Limited the versatility of these parts sometimes owing to the difference slightly of partial structurtes.For example pole plate lug position with weldment sealing position is not matched.Way routinely needs the structure of redesign pole plate or change battery case, lid this moment, and needing to increase mould has thus also increased simultaneously supplies consumption.

Summary of the invention

The objective of the invention is to avoid the deficiencies in the prior art part, propose a kind of by the improvement battery post or to weldment structure or welding manner, to adapt to the scheme of battery middle cover shape, this programme is only done change to pole or to weldment structure or welding manner, just can make a kind of battery middle cover be applied to two or more battery electrode groups, or make that a kind of battery electrode group can adaptive two or more battery middle cover, reduced material loss and mould input.

The present invention realizes by adopting following technical scheme:

The method of implementing a kind of battery post or weldment being connected with bus-bar, described method comprises step:

(1) is inverted in the opposite side of no bus-bar main body with pole or to the side of the transition region below the weldment main body from relative bus-bar main body;

(2) post is arranged the weld zone by a sidesway of relative bus-bar main body place pole or under the weldment main body or dislocation in the opposite side of no bus-bar main body;

(3) make pole or to weldment main body corresponding to the positive battery middle cover to weldment sealing position;

(4) in post row weld zone transition region and bus-bar are welded;

(5) carry out follow-up cell package operation.

Realize a kind of battery post of said method or to the weldment structure, comprise pole or weldment main body, transition region are reached the post row weld zone that connects with bus-bar that key is:

Transition region is positioned at a side of no bus-bar main body.

Post row weld zone is positioned at pole or under the weldment main body or be positioned at a side of no bus-bar main body.

Described pole or to the particular location of weldment main body be positioned to cover in the battery corresponding sealing position under.

Compared with prior art, the present invention is by changing pole or to the particular location of the relative bus-bar of weldment main body, makes that a kind of battery middle cover can adaptive two or more battery electrode group, thereby reduced the battery manufacturing cost.

Embodiment

Below in conjunction with accompanying drawing and two embodiment the present invention is further described in detail.

With reference to Fig. 8, the battery middle cover 50 of CTA12-125X type storage battery, it is to the edge of weldment sealing position 40 near lid, and the bus-bar main body 20 of CT12-180X storage battery shown in Figure 9 overlaps with sealing position 40, cause pole or the position of weldment main body 10 is not complementary with it, though other sizes all are consistent, the two can not be assembled together.Its reason is pole as shown in Figure 1 and Figure 2 or is that direct level is connected with pole or to weldment main body 10 to the transition regions 11 below the weldment main body 10, direct again then horizontal joint pin row weld zone 30, after going the direct again level in post row weld zone 30 to connect bus-bar 20, the three point-blank, make pole or to weldment main body 10 away from bus-bar main body 20.

In order to be withdrawn on the bus-bar main body 20 with pole or to weldment main body 10, the invention process as Fig. 3, Fig. 4, Fig. 5, battery post shown in Figure 6 or the method that weldment is connected with bus-bar, comprising:

(1) is inverted in the B district of no bus-bar 20 main bodys from the A district that bus-bar 20 main bodys are arranged with pole or to the transition region 11 below the weldment main body 10;

(2) execution mode one with post arrange weld zone 30 by the A district dislocation that bus-bar 20 main bodys are arranged in pole or under to weldment main body 10 or, execution mode two dislocations are in the B district of no bus-bar 20 main bodys;

(3) make pole or corresponding to 10 pairs of positive battery middle covers 50 of weldment main body to weldment sealing position 40;

(4) in post row weld zone 30 transition region 11 and bus-bar are welded;

(5) carry out follow-up cell package operation.

, comprise pole or weldment main body 10, transition region 11 and the post that connects with bus-bar 20 arranged weld zone 30 the weldment structure by storage battery that said method produced,

Described transition region 11 is positioned at the B district of no bus-bar 20 main bodys.Described post row weld zone 30 is positioned at pole or under the weldment main body 10 or be positioned at the B district of no bus-bar 20 main bodys, makes described pole or be positioned on the battery middle cover 50 corresponding under the weldment sealing position 40 to weldment main body 10.

As shown in figure 10, according to the battery electrode group 60 that method of the present invention is produced, its outermost pole or the weldment main body 10 and the outermost of battery middle cover 50 shown in Figure 8 mated fully to weldment sealing position 40.

Facts have proved that the present invention is by changing pole or to the particular location of the relative bus-bar of weldment main body, make that a kind of battery middle cover can adaptive two or more battery electrode group, thereby reduced the battery manufacturing cost.
