Anode ear on positive plate is connected by positive bus, and the negative electrode lug on the negative plate of the second single pole group passes through cathode
Busbar connector is connected, and the positive bus and the second single pole group negative bus-bar of the first single pole group passes through busbar connector bridge
Connector is connected, and the direction of thickness towards the bridge connector of the positive bus or negative bus-bar is stepped up.
Further, the thickness of the positive bus or negative bus-bar is towards the direction of bridge connector in step type
Increase.
Further, the positive bus or negative bus-bar include upper and lower surfaces, and the upper surface is rank
Ladder type upper surface, the lower surface are plane.
Further, pass through circular sliding slopes between the stepped upper surface.
Further, the shortest distance of the upper surface of the busbar connector to the busbar connector lower surface is 1mm.
Further, the maximum gauge position of the busbar connector is located at the bridge junction that collapses of busbar connector
Further, the thickness minimum thickness of the busbar connector is the 1/5 of maximum gauge.
Further, the thickness of the positive bus or negative bus-bar is towards the direction of bridge connector in plagiohedral
Increase.
Further, the maximum gauge position of the busbar connector is located at the bridge junction that collapses of busbar connector
Further, the thickness minimum thickness of the busbar connector is the 1/5 of maximum gauge.
The present invention provides lead-acid accumulator in busbar connector design, busbar connector consumption of lead can be substantially reduced, improve
Production efficiency.
Detailed description of the invention
Fig. 1 is the box body structure figure of existing lead-acid accumulator；
Fig. 2 is the structure chart of existing pole group；
Fig. 3 is the structure chart of busbar connector of the present invention.
Specific embodiment
The invention will be further described for specific embodiment with reference to the accompanying drawing.
Such as Fig. 1, shown in 2, a kind of lead-acid accumulator, including shell 1, pole group 10.Shell 1 may include six pole groups
11. pole group 10 of mounting groove may include six single pole groups, such as: the first single pole group 2, second 3. 6 lists of single pole group
A pole group is mounted in pole group's mounting groove 11 of shell 1, and the first single pole group 2 includes positive plate and negative plate, the first single pole
Negative electrode lug on the negative plate of group 2 is connected by negative bus-bar 6, and the anode ear on the positive plate of the first single pole group 2 passes through
Negative bus-bar 7 is connected, and the anode ear on the positive plate of the second single pole group 3 is connected by positive bus 9, single pole group's
Negative electrode lug on negative plate is connected by negative bus-bar 8, the positive bus 7 and corresponding second of the first single pole group 2
The cathode pole busbar connector 8 of single pole group 3 is connected by busbar connector bridge connector (not shown).Single pole group of the invention
Quantity can be selected according to actual needs.
Show the structure of positive bus or negative bus-bar of the present invention as shown in Figure 3, other structures of the invention with
Existing battery structure is identical.It is illustrated by taking positive plate busbar connector as an example below.Positive bus 100 is by the anode of positive plate
Ear 5 is connected as one, and positive bus 100 is connected by bridge connector 4 with corresponding negative bus-bar.Positive bus
100 thickness is stepped up towards the direction of bridge connector 4.Positive bus 100 includes upper surface 101 and lower surface,
Upper surface 101 is preferably stepped upper surface, passes through circular sliding slopes between stepped upper surface, to be conducive to take off in production
Mould, lower surface are plane.To the shortest distance of busbar connector lower surface, it is preferably provided as 1mm for the upper surface of busbar connector, in this way can be with
Guarantee the electric conductivity of busbar connector.The maximum gauge position of busbar connector is located at the bridge junction that collapses of busbar connector.Positive bus 100
Thickness it is preferably provided as far from bridge connector 4 with a thickness of close to the 1/5 of the thickness of bridge connector 4, that is, just
The thickness minimum thickness of pole busbar connector 100 is set as the 1/5 of maximum gauge.In addition bridge connector 4 is preferably disposed on busbar connector
Middle position, the middle position negative bus-bar that the maximum gauge position of such positive bus 100 is located at busbar connector can
To be done in the same fashion setting.Upper surface 101 is also possible to inclined-plane, i.e. 100 thickness of positive bus is connected towards bridge
The direction of part increases in plagiohedral, and upper surface is chamfered surface, and lower surface is plane.
The thickness of busbar connector of the invention is arranged, and since no matter electric current is to flow into or flow out, the electric current close to the bridge that collapses is total
It is maximum, therefore no matter the thickness of positive bus thickness or negative bus-bar is all with close for the thickness setting of busbar connector
The direction of bridge connector is increasing, and with the increase of pole plate, electric current is at stepped increase, technology effect of the invention
Fruit is all the more obvious.By taking compacted accumulator 6-12 as an example: the weight of busbar connector can reduce 20%, and a battery can save 20g or so,
Since the lead liquid at pole tails off, cooling velocity is accelerated, therefore the life of 10-20%% is improved relative to traditional bus structures
Efficiency is produced, therefore shortens the production cycle.The present invention provides lead-acid accumulator in busbar connector design, can substantially reduce
Busbar connector consumption of lead improves production efficiency.
