In view of this, main purpose of the present utility model is to provide a kind of square lithium ion battery with aluminum shell.
To reach above-mentioned purpose, what the technical solution of the utility model was realized in：
The utility model embodiment provides a kind of square lithium ion battery with aluminum shell, and the battery includes square aluminum shell, is arranged on
At least two battery cores in parallel, pole, cover plate, connection sheet, lug in square aluminum hull, described at least two battery cores in parallel it is upper
Portion both sides set lug respectively, are connected above the lug of both sides by connection sheet with cover plate, the pole run through cover plate and
Extend to connection sheet.
In such scheme, the cross section of the connection sheet is T-shaped, and the upper surface of the connection sheet is provided with matches somebody with somebody with pole
It is threaded in the hole slot of conjunction, the hole slot.
In such scheme, felt pad is provided between the cover plate and connection sheet.
In such scheme, insulated enclosure circle is provided between the pole and cover plate.
In such scheme, by insulated enclosure circle on the cover board, the lower end of the pole is stud for the upper end of the pole.
Compared with prior art, the beneficial effects of the utility model：
On the premise of the utility model is accurately positioned in welding, the risk of cover plate gas leakage can either be reduced, can be carried again
High efficiency；Can also effectively control battery core be connected with cover plate after height, it is to avoid when battery core enters shell lug be squeezed and
It is damaged.
Brief description of the drawings
Fig. 1 provides a kind of explosive view of square lithium ion battery with aluminum shell for the utility model embodiment；
Fig. 2 provides a kind of structural representation of square lithium ion battery with aluminum shell for the utility model embodiment.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain
The utility model, is not used to limit the utility model.
The utility model embodiment provides a kind of square lithium ion battery with aluminum shell, as shown in Figure 1, 2, and the battery includes square
Aluminum hull 8, be arranged in square aluminum hull 8 at least two battery cores 6 in parallel, pole 1, cover plate 3, connection sheet 5, lug 7, it is described at least
The top both sides of two battery cores 6 in parallel set lug 7 respectively, and the top of lug 7 of both sides is connected by connection sheet 5 with cover plate 3
Connect, the pole 1 is through cover plate 3 and extends to connection sheet 5.
The cross section of the connection sheet 5 is T-shaped, and the upper surface of the connection sheet 5 is provided with the hole coordinated with pole 1
It is threaded in groove, the hole slot, the depth of the hole slot and it is big neglect the lower end stud size of pole 1 depending on, so, only need machinery
Power is that connection sheet 5 can be made to be fitted close with pole 1, can either so reduce the risk of the gas leakage of cover plate 3 (because of laser welding connection
The high temperature produced during piece can be able to dissolve the insulated enclosure circle 2 between pole 1 and cover plate 3), production efficiency can be improved again.
Felt pad 4 is provided between the cover plate 3 and connection sheet 5.
Insulated enclosure circle 2 is provided between the pole 1 and cover plate 3, the upper end of the pole 1 passes through insulated enclosure circle 2
On cover plate 3, the lower end of the pole 1 is stud.
Insulation effect is played by felt pad 4, insulated enclosure circle 2.
The top both sides of described at least two battery cores 6 in parallel complete at least two battery cores 6 by the lug 7 set respectively
Parallel connection, then pass through connection sheet 5 so that battery core 6, lug 7, connection sheet 5 turn into an entirety, and so, the connection sheet 5 can
Enough effective control battery cores 6 be connected with cover plate 3 after height, lug 7 is squeezed and damaged when can also avoid the battery core 6 from entering shell.
If necessary to which more than two battery cores 6 are in parallel, it is still and is welded respectively in the top both sides of more than two battery cores 6
Connect lug 7.
Assembling process of the present utility model：
The upper end of the pole 1 is sealed on cover plate 3 by insulated enclosure circle 2, then places felt pad 4, the connection sheet 5
The lower end of hole slot and pole 1 assemble, that is, complete pole 1, cover plate 3 and the connection of connection sheet 5；Then by the lug of 2 battery cores 6
7 respectively with laser welding in the both sides of the lower end of connector 5, that is, complete the parallel connection of two battery cores 6, the connection sheet 5 and battery core 6
As an entirety；Battery core 6 is finally put into square aluminum hull 8, welded cover plate 3 and square aluminum hull 8, that is, the assembler for completing battery
Sequence.
Described above, preferred embodiment only of the present utility model is not intended to limit protection of the present utility model
Scope.
