Description
Technical field
The invention belongs to cell art, particularly to a kind of attachment structure and processing technology thereof.
Background technology
Existing electrokinetic cell can be used aluminum be flexible coupling, or entitled Bus-Bar, in order to be connected with battery copper electrode, need
Aluminum be flexible coupling (Bus-Bar) plate electroless nickel layer or silver layer, but because this electroplating processes is local plating, due to the valency of local plating
Lattice are higher, and plating thickness and color are unstable.
Based on this, industry develops the welding product of a kind of aluminium foil+nickel sheet, from without (the Bus-that is flexible coupling aluminum
Bar) electroplating processes is carried out, time-consuming, reduce cost, and improve stability.
Summary of the invention
An object of the present invention is: for the deficiencies in the prior art, and provides a kind of attachment structure, this attachment structure
Solve that prior art electroplating processes is relatively costly, lose time, technical problem that stability is bad.
For achieving the above object, the present invention adopts the following technical scheme that
A kind of attachment structure, connects sheet including a connecting piece and second, and described a connecting piece is copper sheet or aluminium flake, and described the
Two connect sheets be nickel sheet or silver strip, described a connecting piece include Hard link part and and soft with what described Hard link part was connected
Coupling part, described second connects sheet thermal compression welding in the Hard link part of described a connecting piece.A connecting piece and second
The welding manner connecting sheet is: (mode of heating comprises but is not only electricity for macromolecule diffusion welding (DW) or other mode of heating thermal compression welding
Pole is heated, electric-heating-wire-heating, carbon-point heating etc.), the thermal compression welding mode of welding of pressurizeing through cylinder or hydraulic cylinder so that this
Nickel sheet or silver strip, in the case of without any auxiliary agent, are welded to the surface of a connecting piece, are eventually fabricated power by invention
Battery circuit connects uses soft or hard attachment structure, so ensures good electric conductivity, and solution battery electrode copper turns aluminum or aluminum turns copper
A difficult problem.
As a kind of improvement of attachment structure of the present invention, described a connecting piece is by copper sheet more than at least two-layer
Or aluminium flake thermal compression welding forms, the thickness of every layer is 0.05 ~ 0.25mm.
As a kind of improvement of attachment structure of the present invention, described Hard link part has connecting hole.
As a kind of improvement of attachment structure of the present invention, described flexible joint part is set to arc structure.
As a kind of improvement of attachment structure of the present invention, the described second thickness connecting sheet is 0.05 ~ 1.0mm.
Further object is that the processing technology that a kind of attachment structure is provided, comprise the steps:
A, be ready to a connecting piece and second connect sheet, described a connecting piece is copper sheet or aluminium flake, described second connect sheet
For nickel sheet or silver strip, described a connecting piece includes Hard link part and and the portion that is flexible coupling that is connected with described Hard link part
Point；
B, then connect sheet thermal compression welding in the Hard link part of a connecting piece by second so that a connecting piece and second is even
Contact pin shape is integral, thus forms above-mentioned attachment structure.
Accompanying drawing explanation
Fig. 1 is one of structural representation of the present invention.
Fig. 2 is the two of the structural representation of the present invention.
Fig. 3 is the sectional view of the present invention.
Detailed description of the invention
Below in conjunction with detailed description of the invention and Figure of description, the present invention is described in further detail, but the present invention
Embodiment be not limited to this.
Embodiment 1
As shown in Fig. 1 ~ 3, a kind of attachment structure, connect sheet 2 including a connecting piece 1 and second, a connecting piece 1 be copper sheet or
Aluminium flake, the second connection sheet 2 is nickel sheet or silver strip, and a connecting piece 1 includes Hard link part 11 and and connects with Hard link part 11
The flexible joint part 12 connect, the second connection sheet 2 thermal compression welding is in the Hard link part 11 of a connecting piece 1, and second connects sheet 2 can
To be set to two panels, two panels second connects sheet 2 can distinguish thermal compression welding in the upper and lower surface of a connecting piece 1, and certainly, second even
Contact pin 2 could be arranged to a piece of, and a piece of second connects sheet 2 thermal compression welding in the upper surface of a connecting piece 1 or surface.The present invention
The quantity of Hard link district part 11 be one or multiple, the quantity of flexible joint part 12 is one or more, one or many
Individual flexible joint part 12 connects two adjacent Hard link parts 11, and Hard link part 11 generally flat configuration, be flexible coupling portion
12 are divided to be traditionally arranged to be arc structure, when the present invention is arranged in battery module structure, the flexible joint part 12 of arc structure
The effect of damping can be played, improve the service life of the present invention.
Preferably, a connecting piece 1 is formed by copper sheet more than at least two-layer or aluminium flake thermal compression welding, and the thickness of every layer is
0.05~0.25mm.Can effectively ensure the soft of flexible joint part 12 in the range of this, shake so that product can effectively absorb
Energy, prevents damaged products.
Preferably, Hard link part 11 has connecting hole 111, is connected on the pole of battery by connecting hole 111, typically
