Detailed description of the invention
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect more clear bright
In vain, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that
Specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
As shown in Figures 2 and 3, for a preferred embodiment of the present utility model, a kind of battery includes that block is tied
Structure 100, battery container 200 and Reserve Power Division (not shown), capping structure 100 is passed through in Reserve Power Division
It is sealed in battery container 200.Battery cap structure 100 includes the top cover installed that is electrically connected the most successively
10, rustless steel packing ring 20, bound edge burst disk 30, current blocking device 40 and cladding top cover 10 and bound edge are prevented
The outer peripheral sealing ring 50 of quick-fried 30, the middle part of bound edge burst disk 30 is to lower process, jut and electricity
Stream block device 40 welds.Capping structure also includes that insulating ferrule 60, insulating ferrule 60 are coated with top cover 10 He
The outward flange of bound edge burst disk 30, and it is positioned at the inner side of sealing ring 50.Insulating ferrule 60 is positioned at top cover 10
One end of upper surface stretch out sealing ring 50, and extend certain distance to top cover 10 center and form covering part 61,
Concrete distance is configured according to actual needs.Owing to covering part 61 will be close to the part top of battery container 70
Lid 10 covering, be equivalent to add top cover 10 and battery container 200 contacts distance, greatly reduces top
The probability that lid 10 contacts with battery case 70, thus it is greatly reduced the risk of battery short circuit.
Specifically, bound edge burst disk 30 and current blocking device 40 by laser welding, when battery overcharge or
During short time heavy-current discharge, a large amount of gas can be produced.Gas reaches certain pressure, is first prevented by bound edge
The ledge of quick-fried 30 is flipped up, and breaks and the pad of following current blocking device 40, makes battery
Terminate continuing charge and discharge, it is ensured that use safety.Insulating ferrule 60 is positioned at bound edge burst disk 30 lower surface
One end stretch out sealing ring 50, and be placed between bound edge burst disk 30 and current blocking device 40.So exist
When bound edge burst disk 30 breaks the pad between current blocking device 40, insulating ferrule 60 can play resistance
Gear current blocking device 40 is followed bound edge burst disk 30 and is moved up, and beneficially bound edge burst disk 30 hinders with electric current
The timely disconnection of disconnected device 40, prevents battery explosion.
In the present embodiment, top cover 10 projection laterally forms positive terminal 11, and positive terminal 11 is for outside
Circuit electrically connects, and positive terminal 11 is internal offers screwed hole.Negative terminal 210 also it is equipped with on battery container 200,
Positive terminal 11 and negative terminal 210 lay respectively at the two sides that battery is relative.Negative terminal 210 outer peripheral edge is offered
There is the screw thread closed with corresponding threaded holes.Owing to the electricity of single battery is limited, it usually needs by multiple battery strings
Connection meets needs.As shown in Figure 4, when adjacent cell is connected, negative terminal 210 side of being threaded connection
Formula is inserted in the screwed hole of positive terminal 11.So can substitute the mode of welding, it is to avoid welding process goes out
Existing rosin joint or not prison welding, cause set of cells internal resistance bigger than normal, and even safety problem avoids welding process simultaneously
Protective layer for positive terminal 11 surface destroys and causes problem of rustiness, it is ensured that the service life of battery.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model,
All any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, all should
Within being included in protection domain of the present utility model.
