Abstract
The utility model discloses a kind of battery pack busbar structure, including aluminium conductive bar, nickel sheet and bolt, the output of the aluminium conductive bar is extremely provided with screwed hole, manhole is provided with nickel sheet, two nickel sheet difference thermal compression weldings are exported in aluminium conductive bar in extreme upper and lower ends face, and the screwed hole on the manhole and aluminium conductive bar in nickel sheet connects, bolt is located in manhole and screwed hole.Aluminium busbar structure of the present utility model is reliable, equivalent to aluminium nickel plating, the surface of nickel plating is easy to damage, but the structural strength of thermal compression welding nickel sheet is higher than aluminium nickel plating, electrochemical corrosion low with the conductive copper wire contact resistance for coupling battery pack by aluminium conductive bar after hot pressing nickel sheet, and avoiding copper aluminium from directly contacting, in the case where meeting performance requirement, the relatively existing mode for needing copper aluminium to transfer, simple in construction, cost reduces.
Description
Technical field：
It the utility model is related to a kind of battery pack busbar structure.
Background technology：
The conductive bar of the electronic vapour battery pack of existing square electric cell composition is aluminium material, and aluminium can not directly with battery pack phase
The conductive copper wire being mutually coupled with is attached, and otherwise not only contact resistance is big, and can produce electrochemical corrosion.Prior art is usual
After taking aluminium conductive bar ultrasonic bonding copper electrode, then it is attached with coupling the conductive copper wire of battery pack by copper electrode, into
This height, complex process.
Utility model content：
The utility model is to solve a kind of battery pack busbar structure that copper aluminium can not directly be contacted and taken.
There is technical scheme used by the utility model：A kind of battery pack busbar structure, including aluminium conductive bar, nickel sheet and
Bolt, the output of the aluminium conductive bar are extremely provided with screwed hole, and manhole is provided with nickel sheet, and two nickel sheet distinguish thermocompression bonding
It is connected on aluminium conductive bar to export in extreme upper and lower ends face, and the manhole in nickel sheet mutually passes through with the screwed hole on aluminium conductive bar
Logical, bolt is located in manhole and screwed hole.
Further, the nickel sheet thickness >=0.1mm.
Further, the output of the aluminium conductive bar is extremely provided with concave part, and nickel sheet thermal compression welding is in the concave part.
Further, the battery core direction of the nickel sheet is arc-shaped edges structure.
The utility model has the advantages that：Aluminium busbar structure of the present utility model is reliable, equivalent to aluminium nickel plating,
The surface of nickel plating is easy to damage, but the structural strength of thermal compression welding nickel sheet is higher than aluminium nickel plating, is led by aluminium after hot pressing nickel sheet
Electric bar is low with the conductive copper wire contact resistance for coupling battery pack, and the electrochemical corrosion for avoiding copper aluminium from directly contacting, and is meeting
In the case of performance requirement, the relatively existing mode for needing copper aluminium to transfer, simple in construction, cost reduces.
Brief description of the drawings：
Fig. 1 is the utility model structure chart.
Fig. 2 is the utility model explosive view.
Embodiment：
The utility model is further described below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, the utility model discloses a kind of battery pack busbar structure, including aluminium conductive bar 1, nickel sheet 2
With bolt 3, the output of aluminium conductive bar 1 is extremely provided with screwed hole 11, and manhole 21 is provided with nickel sheet 2, and two nickel sheet 2 are distinguished
Thermal compression welding is exported in aluminium conductive bar 1 in extreme upper and lower ends face, and on the manhole 21 and aluminium conductive bar 1 in nickel sheet 2
Screwed hole 11 connect, bolt 3 is located in manhole 21 and screwed hole 11.The output of aluminium conductive bar 1 extremely passes through spiral shell
Bolt 3 is connected with coupling the copper connecting line of battery pack.
Thickness >=0.1mm of nickel sheet 2.Concave part 12 is extremely provided with the output of aluminium conductive bar 1, the thermal compression welding of nickel sheet 2 exists
In the concave part 12.
The battery core direction of nickel sheet 2 is arc-shaped edges structure 22 in the utility model, is installed for ease of coordinating, a left side for concave part 12
Side wall is arc-shaped edges.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, some improvement can also be made on the premise of the utility model principle is not departed from, these improvement also should be regarded as
The scope of protection of the utility model.
