Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the schematic diagram that the utility model embodiment connects battery module;
Fig. 3 is used for the user mode figure that battery module connects for the utility model embodiment.
Embodiment
Contrast accompanying drawing and the utility model is further described below in conjunction with embodiment.
Embodiment one
Battery module connector 1 shown in Fig. 1～3 comprises the sheet metal 11 that the both sides and the electrode terminal 21,31 of battery module 2,3 are connected respectively, and sheet metal 11 is provided with three fixing holes 13.
The centre of both sides sheet metal 11 is provided with multilayer arch bridge shape metal forming 12, and arch bridge shape metal forming 12 has elastic buffer function.
Sheet metal 11 is the entity sheet metals that are connected with metal forming 12 by the electron beam welding mode.
The number of plies of metal forming 12 is determined by the size and the charge and discharge current value of the electrode terminal 21,31 of the battery module 2,3 that is connected.
The thickness of metal forming 12 is 0.01mm～5.00mm, is preferably 0.05mm～0.500mm.
Metal forming 12 and sheet metal 11 are preferably copper product, with its resistance of further reduction, and are convenient to welding.
The length direction of sheet metal 11 is provided with the welding wire groove of being convenient to weld 14.
