Embodiment
For ease of skilled artisan understands that the technical solution of the utility model, below by technical side of the present utility model
Case is described in further detail in conjunction with specific embodiments.
As shown in Figure 1, Figure 2 and Figure 3, a kind of electrokinetic cell includes burst disk 20；The burst disk 20 include fixed part 21,
First connecting portion 22, second connecting portion 24 and prejudge portion 23；The fixed part 21 and the vertical connection of first connecting portion 22, just
In machine-shaping；The first connecting portion 22 and the vertical connection of second connecting portion 24, are easy to machine-shaping；Described second connects
Socket part 24 prejudges the vertical connection of portion 23 with described, is easy to machine-shaping；It is described to prejudge portion 23 and be provided with the first pre- fault trough 231 and
Two pre- fault troughs 232；The first pre- opening direction of fault trough 231 is opposite with the described second pre- opening direction of fault trough 232；Described first
Pre- fault trough 231 includes the first side wall 2311, and the first side wall 2311 is just corresponding to the described second pre- fault trough 232；Described second is pre-
Fault trough 232 includes second sidewall 2321, and the second sidewall 2321 is just corresponding to the described first pre- fault trough 231；The first side wall
2311 and the second sidewall 2321 along perpendicular to pressure directions a formed the region of fracture, when air pressure is too high, the region of fracture breaks
Split, the separation of portion 23 is prejudged so as to described in and is easy to gas to discharge, so as to prevent the electrokinetic cell from exploding；The structure of burst disk 20
Simply, it is only necessary to injection or punch forming into etc. wall thickness structure, and the first pre- 231 and second pre- fault trough of fault trough described in post-processing
232；Simple in construction, production cost is low；It is pre- using the first pre- fault trough 231 and second in the burst disk 20 of battery cap 100
The two-sided stability prejudged bat laminated structure, mould can be increased of fault trough 232, and preferably management and control burst disk 20 can prejudge effect
Fruit, so as to preferably lift demolition effect, lift the security performance and competitiveness of product.
As shown in Figure 1, Figure 2 and Figure 3, the first side wall 2311 is parallel to pressure directions a；The second sidewall 2321 is flat
Row is in pressure directions a.
