Embodiment

Principle of the present utility model and feature being described below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.

As shown in Figure 1, Figure 2, Figure 3 shows, the laminated bus bar structure of a kind of local overload big current, it comprises positive electrode 1, negative potential 2 and the insulation layer between positive electrode 1 and negative potential 23, and positive electrode 1, negative potential 2 contact with insulation layer 3 successively face and be connected together; Best insulation layer 3 is provided with two layers of insulating film, increases insulation effect like this. Positive electrode 1 is provided with the first copper plug 11, and negative potential 2 is provided with the 2nd copper plug 21, and positive electrode 1 and insulation layer 3 are equipped with the resigning hole facilitating the 2nd copper plug 21 to pass. First copper plug 11 is one-body molded with positive electrode 1,2nd copper plug 21 is one-body molded with negative potential 2, prior art adopt the structure of pin and copper sheet combination as the first copper plug 11, the 2nd copper plug 21, design can reduce component on the one hand like this, avoid coming off of pin, add the reliability of product, realize on the other hand busbar local and transship big current.

As shown in Figure 4, further: the first copper plug 11 adopts ruffle to process, and the thickness of the first copper plug 11 is the twice of positive electrode 1 thickness. Best 2nd copper plug 21 also adopts ruffle to process simultaneously, and the thickness of the 2nd copper plug 21 is the twice of negative potential 2 thickness. Overload big current part (the first copper plug 11, the 2nd copper plug 21) changes ruffle process into, makes busbar local be increased to double thickness, thus realizes busbar local and transship big current.

As shown in Figure 1, further: the first connection terminal 12, first connection terminal 12 that positive electrode 1 is provided with other is one-body molded with positive electrode 1, the 2nd connection terminal the 22, two connection terminal 22 that negative potential 2 is provided with other is one-body molded with negative potential 2.
