Solder-bump, further include the aluminium flake being arranged on the upside of the steel disc that reclines, penetrate through and offer on the aluminium flake: several deformation
Hole and several for being disposed circumferentially each deformation hole periphery deform slots, and punching has several to stretch upwards on the steel disc
Flange out, the flange protrude into the deformation slot, and the expansion device by being inserted into the deformation hole makes the shape aperture
To expanding outwardly deformation, so that the cell wall of the deformation slot squeezes the flange and the flange and the deformation slot is tight
It is solidly connected.
Each solder-bump is in rectangular distribution on the steel disc.
Each deformation hole is in rectangular distribution on the aluminium flake.
Three deformation slots are arranged in each deformation hole periphery, and this three deformation slots are with the deformation hole
The center of circle Kong Xinwei arc-shaped slot.
Three deformation slots of the deformation hole periphery are arranged on same annulus.
The flange is formed and to the steel disc punching flanging bore, the flange is arc-shaped flange, and each
The flanging bore has three flange.
Each flanging bore is in rectangular distribution on the steel disc.
The upper surface of the flange and the aluminium flake is made to recline arrangement to the flange bending process.
The advantages of the application, is:
1, the confluence piece of the application is combined by steel disc and aluminium flake, not only facilitates it solid with the welding of battery steel end face
It is fixed, while there is very strong overcurrent capability.
2, steel disc and aluminium flake are accordingly fixed using special mechanical structure, and structure is simple, easy to make, without welding (steel
It is difficult to solder to aluminium).

Fig. 1 to Fig. 3 shows a this specific embodiment for the compound confluence piece of battery modules of the application, with tradition
The piece that converges is identical to be, which also includes a steel disc 1, the steel disc 1 approximate horizontal arrangement in Fig. 1, there is punching on steel disc 1
Multiple downwardly projecting solder-bumps 101 for being welded and fixed with battery end-face in battery modules.In view of most of batteries
Battery cell in mould group is all at rectangular arrangement, so each solder-bump 101 in the present embodiment is also in square on steel disc 1
Battle array shape distribution.
The key improvements of the present embodiment are that the compound confluence piece, which is also configured with to recline, is arranged in aforementioned 1 upside of steel disc
Aluminium flake 2.Perforation offers multiple deformation holes 201 and multiple deformation slots 202 (or deformation joint) on aforementioned aluminium flake 2, wherein each
Deform hole 201 on aluminium flake 2 be in rectangular distribution, each 201 periphery of deformation hole be respectively provided with there are three deformation slot 202 above-mentioned.
Flange 102 on steel disc 1 protrudes into the deformation slot 202 of aluminium flake 2, and by the expansion device radial compression in insertion deformation hole 201
It deforms hole 201 (hole wall), makes to deform the deformation of 201 radial outward dilations of hole, the process of deformation 201 radial outward dilations of hole deformation
In, can be squeezed and deformed hole 201 and deform slot 202 between aluminium flake, and make the part aluminium flake to deformation 202 displacement of slot,
So that the contraction of deformation slot 202 of shape aperture outward becomes smaller, the deformation slot 202 to become smaller is shunk, cell wall inwardly squeezes
Flange 102 and by flange 102 and deformation 202 snap fit of slot, flange 102 and deformation slot 202 be fastenedly connected, 1 He of downside steel disc
Upside aluminium flake is fastenedly connected.
In the present embodiment, above-mentioned each item deformation slot 202 is arc-shaped slot, and the three of each 201 periphery of deformation hole
The Kong Xinwei same point in item deformation 202 center of circle of slot and the deformation hole 201.Further, aforementioned three deformations slot 202 is arranged in together
On one annulus, and this three deformation slots 202 are around deformation hole uniform intervals arrangement.
It, can be to the circular flanging bore of 1 punching of steel disc, thus in aforementioned flanging bore side for convenience of the production of above-mentioned flange 102
Portion forms above-mentioned flange 102.Under normal conditions, directly 1 punching circle flanging bore of steel disc is formed in the flanging bore side
Flange is a whole continuous round flange, so the round flange to the flanging bore is needed after the good aforementioned flanging bore of punching
It carries out cutting processing, and obtains three spaced apart arc-shaped flange 102.
In order to reinforce the bonding strength of aluminium flake 2 and steel disc 1, bending process can be done to flange 102, and make flange 102 with
The upper surface of aluminium flake 2 reclines arrangement: by stretching out, 102 upper half downward bending of flange outside deformation slot 202 is horizontal, and makes
Flange 102 and 2 upper surface abutting contact of aluminium flake.
Above-mentioned deformation hole 201 is circular hole.
Above-described embodiment is only the technical concepts and features for illustrating the application, and its object is to allow people that can understand this Shen
Content please is simultaneously implemented accordingly, and the protection scope of the application can not be limited with this.It is all according to the application main technical schemes
