The cylindrical aluminium case lithium ion battery of full tab is currently used assembly method, however full extreme ear structure cylindrical aluminium
For housing battery during battery core is shaken, coil diameter/length core less than normal is unable to held stationary in shell, shakes inside housings
It is dynamic, cause tab welding position desoldering.Therefore, core stop frame becomes and guarantees that battery core is smoothly crucial in battery core.Cylinder at present
The common stop frame of battery be it is mechanical, i.e. battery assembly is by stop frame assembly in battery cover plate face, stop after closing lid
Frame stop end face is quite pressed in core by machinery, core is fixed, this means of retention core partially short for core length
Stopping effect is poor, easily causes the over-voltage at tab end damaged the partially long core of core length.Therefore, it is necessary to develop a kind of simultaneous
Core or length or short cylindrical battery are cared for flexible stop frame.
Utility model content
The utility model is mainly solving the technical problems that provide a kind of for fixing the full tab lithium-ion electric in-core of cylinder
The stop frame of volume, can be effectively relieved the full tab battery roll core of cylinder it is different in size caused by core shake, electricity can be effectively increased
The stability of core internal core during shaking.
In order to solve the above technical problems, the technical solution that the utility model uses is: one kind is complete for fixing cylinder
The stop frame of tab lithium-ion electric core curls inward comprising insulating body in the form of annular discs is located on the insulating body and along institute
The symmetrically arranged flexible stop tentacle of insulating body circumferential edge is stated, the height of the flexibility stop tentacle is from centre gradually to both sides
It is incremented by, is provided with compression space, the insulating body and institute between the both ends and the insulating body of the flexibility stop tentacle
Stating flexible stop tentacle is using integrated formed structure made of PFA or fluorubber isolation material.
Further, the first opening that electrolyte is flowed through for liquid injection hole or explosion-proof valve is offered on the insulating body.
Further, it is offered on the insulating body convenient for being open with the second of cover board rivet or weld.
Further, there are two the second opening settings.
Further, the area of single first opening is the 1/20 of the insulating body area.
Further, the area of single second opening is the 1/10 of the insulating body area.
Further, the compression space is by one formed between the insulating body and the flexible stop tentacle
Angle space, the angle are not less than 10 °.
Further, the thickness of the flexible stop tentacle is not less than 1mm, and width is not less than 2mm.
Compared with prior art, the utility model is a kind of for fixing the stop frame of the full tab lithium-ion electric core curls inward of cylinder
Beneficial effect be: tradition machinery formula stop frame has been abandoned, using the deformation elastic force of flexible stop tentacle as entire core pole
The support being in close contact between ear and cover board, had not only increased the stability of core, but also reduced the shape to core tab contact squeeze
Become；It is designed simply, easily operated, causes core in shell with the increase that mould group is vibrated full cylinder tab battery can be effectively relieved
The problem that internal portion persistently shakes, can effectively increase the stability of battery.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment；
Digital representation in figure:
100 for fixing the stop frame of the full tab lithium-ion electric core curls inward of cylinder；1 insulating body；2 flexible stop tentacles；3
Compression space；4 first openings；5 second openings.
Specific embodiment
Embodiment:
The utility model preferred embodiment is described in detail with reference to the accompanying drawing, so that the advantages of utility model and spy
Sign can be easier to be readily appreciated by one skilled in the art, to make apparent specific boundary to the protection scope of the utility model
It is fixed.
Referring to Fig. 1, the utility model embodiment is a kind of for fixing the stop of the full tab lithium-ion electric core curls inward of cylinder
Frame 100 comprising insulating body 1 in the form of annular discs, be located at it is on insulating body 1 and symmetrically arranged along 1 circumferential edge of insulating body
Flexible stop tentacle 2, the height of flexible stop tentacle 2 are gradually incremented by both sides from centre, both ends of flexible stop tentacle 2 and absolutely
Compression space 3 is provided between edge matrix 1, insulating body 1 and flexible stop tentacle 2 is using PFA or fluorubber isolation materials
Manufactured integrated formed structure.
It is offered on insulating body 1 and flows through the first opening 4 of electrolyte for liquid injection hole or explosion-proof valve, is convenient for riveting with cover board
Or the second opening 5 of welding.There are two second opening, 5 settings.Wherein, the area of single first opening 4 is 1 area of insulating body
1/20, it is single second opening 5 area be 1 area of insulating body 1/10.
Compression space 3 is an angle space by being formed between insulating body 1 and flexible stop tentacle 2, the angle
Not less than 10 °, guarantee to provide corresponding elastic force after tentacle angle becomes smaller.
The thickness of flexible stop tentacle 2 is not less than 1mm, and the width of flexible stop tentacle 2 is not less than 2mm, prevents tentacle mistake
It is thin, narrow that corresponding elastic force cannot be provided, guarantee spring ratio.
The utility model embodiment is a kind of for fixing the stop frame 100 of the full tab lithium-ion electric core curls inward of cylinder, passes through
Two pairs of flexible stop tentacles 2 are set on 1 surface of insulating body, increase stop area, while with angled stop tentacle,
When core length is longer, flexible tentacle is oppressed, and tentacle is corresponding to the angle of matrix to become smaller, and guarantees that tab is not stopped frame mistake
Support is provided while compressive strain；When core length is shorter, flexible tentacle can still touch core, when core is shaken, touching
Hand generates corresponding deformation, provides biggish support force, so that core is in relatively stable state, the full tab of cylinder has been effectively relieved
Battery with battery core shaking, core follow shaking cause tab damage or desoldering problem；It is arranged first on 1 surface of insulating body
Opening 4, electrolyte is penetrated into or is flowed out when being conducive to fluid injection, when explosion-proof valve is opened, while can also reduce the quality of insulating substrate,
Be conducive to loss of weight；Simultaneously in the second opening 5 of 1 surface of insulating body setting, guarantee that the stop frame effectively can be connected or be riveted to
On cover board.
A kind of stop frame 100 for fixing the full tab lithium-ion electric core curls inward of cylinder of the utility model embodiment is abandoned
Tradition machinery formula stop frame, using the deformation elastic force of flexible stop tentacle as being in close contact between entire core tab and cover board
Support, had not only increased the stability of core, but also reduce the deformation to core tab contact squeeze；It is designed simply, is easy to grasp
Make, full the difficulty that cylinder tab battery causes core persistently to shake inside housings with the increase that mould group is vibrated can be effectively relieved
Topic, can effectively increase the stability of battery.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in
Other related technical areas are also included in the patent protection scope of the utility model.
