Abstract
The utility model is related to a kind of positive and negative anodes connection sheets of power battery, include being made of connection sheet egative film, the first bending circular arc, the first bending part, the second bending circular arc and the second bending part that monoblock metal plate connection continuous bending is formed twice, first bending part is overlapped with connection sheet egative film in 180 degree, and second bending part and the first bending part are in 90 degree.The metal plate egative film is molded using mould punching.First bending part is connect by the first bending circular arc with connection sheet egative film.180 degree is U-shaped is superimposed together for first bending circular arc rotation.Second bending part is connect by the second bending circular arc with the first bending part.The utility model connection sheet uses continuous bending integral structure twice, saves assembling process, improves production efficiency, integral structure increases area of passage, improves the overcurrent performance of connection sheet.
Description
Technical field
The utility model belongs to the technical field of New-energy electric vehicle, more specifically, the utility model is related to one kind to move
The positive and negative anodes connection sheet of power battery.
Background technology
Increasingly perfect with electric vehicle engineering, electric vehicle and hybrid electric vehicle are increasingly from daily life
Closely, there is huge business opportunities, while electric vehicle proposes more to providing the security performance of the lithium ion battery of energy for it
High requirement.For the performance of battery core is effectively ensured, the anode ear of naked battery core and negative electrode lug need to be forwarded to the cover board of hull outside
On.Existing secondary cell is by assembling the connection sheet on the lug and cover board of naked battery core, to realize electric current by battery core
Inside be conducted to outside battery core.Now widely used connection sheet is as shown in Figure 1, by a piece of smooth connection sheet and a piece of bending
90 degree of connection sheet superposition, carries out man-made assembly, there are disadvantages for this connection sheet by the way of being manually assembled：1, using artificial
Packaging efficiency is low, influences the production capacity of integral product；2, smooth connection sheet and the superposition assembling of the connection sheet of 90 degree of bending, reduced
Flow area, safety are poor.
Utility model content
In order to solve the problem of existing power battery connection sheet low production efficiency overcurrent poor performance, the utility model proposes
A kind of positive and negative anodes connection sheet of power battery.
The utility model is to realize that above-mentioned target adopts the technical scheme that：
A kind of positive and negative anodes connection sheet of power battery includes the connection formed twice by monoblock metal plate connection continuous bending
Piece egative film, the first bending circular arc, the first bending part, the second bending circular arc and the second bending part composition, first bending part with
Connection sheet egative film is overlapped in 180 degree, and second bending part and the first bending part are in 90 degree.
The metal plate is molded using mould punching.
First bending part is connect by the first bending circular arc with connection sheet egative film.
180 degree is U-shaped is superimposed together for first bending circular arc rotation.
Second bending part is connect by the second bending circular arc with the first bending part.
The beneficial effects of the utility model：1, connection sheet uses continuous bending integral structure twice, saves assembling process,
Improve production efficiency；2, integral structure increases area of passage, improves the overcurrent performance of connection sheet.
