Detailed description of the invention
Below in conjunction with accompanying drawing specific embodiment, the invention will be further described.
Such as Fig. 1, shown in 2, a kind of lead-acid accumulator, including housing 1, pole group 10.Housing 1 can include six pole group's mounting groove 11. pole group 10 can include six single pole groups, as: the first single pole group 2, the second single pole group of single pole group 3. 6 is arranged in pole group's mounting groove 11 of housing 1, first single pole group 2 includes positive plate and negative plate, negative electrode lug on the negative plate of the first single pole group 2 is connected by negative bus-bar 6, anode ear on the positive plate of the first single pole group 2 is connected by negative bus-bar 7, anode ear on the positive plate of the second single pole group 3 is connected by positive bus 9, negative electrode lug on the negative plate of single pole group is connected by negative bus-bar 8, the positive bus 7 of the first single pole group 2 is connected by bus-bar bridge connector (not shown) with the negative pole pole bus-bar 8 of the corresponding second single pole group 3.Single pole group's quantity of the present invention can select according to actual needs.
Showing the structure of positive bus of the present invention or negative bus-bar as shown in Figure 3, other structures of the present invention are identical with existing battery structure.Illustrate for positive plate bus-bar below.The anode ear 5 of positive plate is connected as one by positive bus 100, and positive bus 100 is connected with corresponding negative bus-bar by bridge connector 4.The thickness of positive bus 100 is being stepped up towards the direction of bridge connector 4.Positive bus 100 includes upper surface 101 and lower surface, and upper surface 101 is preferably notch cuttype upper surface, and by circular sliding slopes between notch cuttype upper surface, thus being conducive to producing the demoulding, lower surface is plane.The upper surface of bus-bar it is preferably provided as 1mm to the beeline of bus-bar lower surface, so can ensure that the electric conductivity of bus-bar.The maximum gauge position of bus-bar is positioned at the bridge junction that collapses of bus-bar.The thickness of positive bus 100 it is preferably provided as the thickness away from bridge connector 4 is the thickness near bridge connector 4 1/5, and namely the thickness minimum thickness of positive bus 100 is set to the 1/5 of maximum gauge.Additionally bridge connector 4 is preferably disposed on the centre position of bus-bar, and the maximum gauge position of such positive bus 100 is positioned at the centre position of bus-bar. and negative bus-bar can be configured in the same way.Upper surface 101 can also be inclined-plane, and namely positive bus 100 thickness is that plagiohedral increases towards the direction of bridge connector, and upper surface is chamfered surface, and lower surface is plane.
The thickness of the bus-bar of the present invention is arranged, owing to no matter electric current is to flow into or flow out, always maximum near the electric current of the bridge that collapses, therefore the thickness of bus-bar arranges positive bus thickness or the direction that the thickness of negative bus-bar is all as near bridge connector is increasing, and along with the increase of pole plate, electric current becomes stepped increase, and the technique effect of the present invention is all the more obvious.For compacted accumulator 6-12: the weight of bus-bar can reduce 20%, one battery can save about 20g, and owing to the plumbous liquid at pole place tails off, rate of cooling is accelerated, therefore improve the production efficiency of 10-20%% relative to tradition bus structures, therefore shorten the production cycle.The design of bus-bar in the lead-acid accumulator that the invention provides, it is possible to be substantially reduced bus-bar consumption of lead, improves production efficiency.
