Spend highest, cycle life most long battery.Lithium ion battery just surmounted rapidly within the short more than ten years Ni-MH battery, NI-G,
Other secondary cell products such as lead-acid battery, in mobile phone, notebook computer, digital camera, electric motor car, electric tool, too
Sun can generate electricity, wind-power electricity generation, raise energy power station be widely used.
Existing sealed cell cap, which coordinates to be matched somebody with somebody by glue sealing groove and plastics inserted sheet, to be combined into, the modeling in glue sealing groove
Material inserted sheet can be moved freely to a certain extent, and such structure design for being used for the shell cover structure of lithium ion battery is not enough closed
Reason, is laid out inadequate science, and performance is less reliable, and this can cause many bad consequences.
The content of the invention
The purpose of this utility model is to provide a kind of power battery cover shell, with asking for solving to propose in above-mentioned background technology
Topic.
To achieve the above object, the utility model provides following technical scheme：
A kind of power battery cover shell, including the injection of upper cover plate, upper cover plate, rivet, terminal post, screw, positive pole pressing plate, absolutely
Embolium, burst disk and negative pole pressing plate, power battery cover shell is strip, is divided into anode portion and cathode portion, and Gai Ke centers are set
There is burst disk, burst disk both sides are provided with insulating trip, and the anode portion middle part sets positive pole pressing plate, cathode portion pars intermedia
Position sets negative pole pressing plate, and positive pole pressing plate and each symmetric design of negative pole pressing plate surrounding have 4 rivets, and positive pole pressing plate and negative pole pressing plate are logical
Cross 4 rivets to be fixed on lid shell, the centers of 4 rivets is provided with screw, the bottom of screw and positive pole pressing plate and
The junction of negative pole pressing plate is provided with terminal post, and the lid shell both sides are provided with upper cover plate, and the afterbody of upper cover plate is noted provided with upper cover plate
Modeling.
It is used as further program of the utility model：The anode portion and cathode portion are set along lid shell Central Symmetry
Meter.
It is used as the utility model further scheme：The screw is preferred to use specification M8 screw.
Compared with prior art, the beneficial effects of the utility model are：The utility model is simple in construction, inside increase design
Burst disk and insulating trip, insulating trip are prevented effectively from the generation of battery short circuit；And make lid shell structure intensity height, insulating properties more
Good, burst disk is can effectively to reduce the harm that blast is produced after battery produces blast, and security performance greatly strengthens
.
Brief description of the drawings
