The wiring terminals are connected with poles of a battery, and all the poles can be elastically connected through the arc-shaped bump structures on the conductive sheets and the connecting blocks with the arc-shaped bump structures; meanwhile, the current sharing effect can be achieved by the connecting blocks.
Description
Technical field
The present invention relates to a kind of bus-bar, be specifically related to a kind of bus-bar supporting power brick high-power applications.
Background technology
In large-scale energy-storage system, cell needs to realize the capacity of energy-storage system and the expansion of power characteristic by parallel connection, in order to support the application of big current, just needs to carry out bus-bar and connect between the pole of therefore cell.Because battery has deformation when charge and discharge point, just need to be connected with elasticity between each pole, avoid the stress between battery with bus-bar to shine into the damage of battery electrode column, and existing bus-bar does not also possess such characteristic.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of bus-bar supporting power brick high-power applications, the elasticity achieved between each pole connects.
In order to achieve the above object, the technical solution adopted in the present invention is:
A kind of bus-bar supporting power brick high-power applications, comprise polylith conducting strip, every block conducting strip is provided with pair of terminals, this pair of wire connection terminals is arranged along the length direction of conducting strip, one section of conducting strip between this pair of wire connection terminals is arc convex structure, described arc convex structure is arranged along the Width of conducting strip, contiguous block is provided with between described adjacent conductive sheet, described contiguous block is also arc convex structure, two curved ends of the contiguous block of arc convex structure play connection respectively at the arc male structure of adjacent conductive sheet, the arc male structure of described contiguous block and conducting strip connects and composes a whole arc convex structure.
The center of arc convex structure between two binding posts on described conducting strip.
Described arc convex structure is arc-shaped convex structure.
Described conducting strip is copper current-conducting piece, and described contiguous block is copper contiguous block.
All conducting strips and all contiguous block integrally castings shaping.
Arc convex structure on adjacent conductive sheet and the contiguous block between adjacent conductive sheet are on same straight line.
The beneficial effect that the present invention reaches: the binding post that the present invention passes through connects the pole of battery, the elasticity achieved between each pole by the contiguous block of the arc convex structure on conducting strip and arc convex structure is connected, and contiguous block also can play current-sharing simultaneously.
