Two side faces 15, and, each second side 15 all connected with two first sides 14.
Collector plate 1 has expansion and bending two states, Fig. 1 and Fig. 8 is the deployed condition of collector plate 1, in deployed condition
Under, lug linkage section 11 can be connected with the lug in naked battery core, and pole linkage section 13 can be connected with the pole on top cover.
And, collector plate 1 can bend and so that collector plate 1 is in bending state in weak section 12, as shown in figure 9, working as
After collector plate 1 is connected with lug, pole respectively, collector plate 1 can be placed in bending state, will lug linkage section 11 near the
To being in a non-zero included angle with pole linkage section 13, now, collector plate 1 is in bending state to one side to overturn of one side 14.And
Naked battery core after connection, top cover and collector plate 1 can be assembled in electrokinetic cell as semi-finished product, this approach increases naked electricity
Space when core positions and is connected with collector plate 1, reduces difficulty during connection.
It is desirable to the intensity of weak section 12 is less and be easy to bend in the application.According to an embodiment, weak section 12 is permissible
It is arranged to thin segment so that the thickness of this thin segment is less than the thickness of collector plate 1 other parts.Due to thin segment have less
Bending strength, therefore collector plate 1 are easily in thin segment bending.

When avoiding bending using equipment, naked battery core and top cover are caused to damage.
As seen in figs. 5-6, in embodiment two, further the quantity of the second opening 12b can also be set to two, two
Individual second opening 12b is separately positioned in a second side 15 and is oppositely arranged.The program relatively arranges a second opening 12b
Compare, lug linkage section 11 is more prone to overturn, and operating physical force when overturning reduces further.
When weak section 12 is set to the second opening 12b, lead to collector plate 1 in order to avoid crack occurring in weak section 12
Cracking, the preferably second opening 12b is circular curve 141 with the intersecting lens of first side 14, so, when lug linkage section 11 here
During place's upset, stress concentration phenomenon will be reduced at the second opening 12b, reduce the risk that fracture in collector plate 1.
In correlation technique, a usual collector plate 1 is connected with the lug of a naked battery core, when there being multiple naked battery core, collection
The quantity of electroplax 1 also needs accordingly to increase.As shown in figure 1, for the usage quantity reducing collector plate 1, preferably each collector plate 1 wraps
Include two lug linkage sections 11 and two weak sections 12, each lug linkage section 11 is passed through a weak section 12 and is connected with pole
Section 13 connection.So, a collector plate 1 just can be connected with two lugs, decreases the quantity of collector plate 1.
According to an embodiment, two lug linkage sections 11 can respectively from pole linkage section 13 to side away from each other
Extend and be symmetrical arranged.For example, two lug linkage sections 11 are formed as T-shaped structure or Y-shaped structure with pole linkage section 13, for
T-shaped structure, two horizontal segments are respectively a lug linkage section 11, and vertical section is pole linkage section 13, for Y-shaped structure, on
Two tilting sections of side are respectively a lug linkage section 11, and the vertical section of lower section is pole linkage section 13.Above-mentioned two lugs are even
Connect section 11 and be symmetrical structure, good manufacturability during its processing, good manufacturability when being connected with lug.
