(2) bending forms the stereochemical structure of cantilever part 2.
Preferably, the bottom fold of (3) cantilever part 2 forms R cambered surface 3 and faces 4 directly.
Preferably, the top bending of (4) cantilever part 2 forms arc surface 5 and ending plane 6.
Preferably, when shell fragment design height is relatively low, having the advantage that when shell fragment is compressed to extreme position by external force, the arc-shaped edges of ending plane can touch installation panel, prevents shell fragment from producing plastic deformation because of excess compression；Simultaneously, described cantilevered beam section more convenient employing length spaced design, cantilever beam can have new arrangement, i.e. increase the cantilever beam that 1 length is shorter between the cantilever beam that each two is longer, increasing the cantilever beam quantity of many 1 times, entirety reduce further contact surface resistance and volume resistance.
Preferably, when shell fragment design height is higher, the central area below described cantilever part, possibly together with a lid, supports separable contact jaw above lid, equipped with 1 or many springs below lid, advantage is as follows: lid can prevent contact flat spring from producing plastic deformation because of excess compression；It addition, spring can increase the overall elastic force of circular multi-disc contact electroconductive elastic sheet further, further increase the vibration resistance of overall shell fragment.
The contact electroconductive elastic sheet of a kind of annular of this utility model, the conductive component being mainly used in end contact connects, and especially battery end-face contact is conductively connected, the electrokinetic cell of such as new-energy automobile.
This utility model achieves the end face that electric current is big, voltage is high, space is narrow well and is conductively connected, solve its contact surface resistance using conical compression spring traditional approach to cause and the bigger problem of volume resistance, it is achieved reliable separable end contact is conductively connected.
