The conducting layer of the busbar extends outwards to form a terminal structure, and the terminal structure is a composite structure of metal aluminum and a metal nickel sheet. The composite structure of the metal aluminum and the metal nickel sheet of the terminal structure is characterized in that the metal aluminum and the metal nickel sheet are fixedly connected in a welding mode. The utility model has the advantages that: the utility model uses the metal aluminum as the conductive layer of the power battery integrated busbar, thereby effectively reducing the cost of the integrated busbar and simultaneously reducing the weight of the bottom busbar; the utility model discloses the terminal that power battery integrated mother arranged adopts metal nickel piece and metal aluminium to carry out the complex, carries out fixed connection through the welded mode, has guaranteed the stability of the female electrical property of arranging of power battery integration, has avoided the copper aluminium composite sheet to need electroplate and the unstable scheduling problem of performance.
Description
Technical Field
The utility model relates to a power battery is integrated female the arranging field, especially a power battery is integrated female arranging with composite terminal structure.
Background
The positive and negative electrode plates of the conventional power battery cell integrated busbar are mainly made of copper-aluminum composite plates, copper-aluminum splicing plates or aluminum 1060O-shaped plates, the copper-aluminum composite plates are high in cost, the surfaces of the copper-aluminum composite plates are further required to be subjected to electroplating treatment due to the fact that copper materials are easy to oxidize, and the welding stability of the power battery cell integrated busbar and the power battery cell is influenced due to different copper-aluminum welding parameters. The copper-aluminum splice plate has high material cost, and the copper and the aluminum can be separated during surface electroplating treatment. When the aluminum 1060O-state material is used, the material cost is low, but the defect is that the aluminum material is easy to damage due to the soft material and the disassembly and the assembly of the screw, and the electric conductivity is influenced. Therefore, a power battery integrated busbar structure with excellent performance and low cost is needed to meet the requirements of high reliability and low cost.
SUMMERY OF THE UTILITY MODEL
The utility model provides a reliable quality, the female row of low price power battery stromatolite, the utility model provides a following technical scheme:
the utility model provides a power battery integration of composite terminal structure is female arranges, power battery integration is female to be arranged and is included conducting layer and insulating layer, the material of conducting layer is metallic aluminum.
As an optimized scheme of the utility model, the conducting layer of female arranging outwards extends and has terminal structure, terminal structure is the composite construction of metal aluminium and metal nickel piece.
As another preferred scheme of the utility model, the composite construction of metallic aluminum and metallic nickel piece of terminal structure, through welded mode fixed connection between metallic aluminum and the metallic nickel piece.
As another preferable embodiment of the present invention, the shape of the metal nickel plate is identical to the shape of the metal aluminum terminal.
As another preferred scheme of the utility model, the thickness of the metal nickel sheet is 0.1mm ~ 1 mm.
The utility model has the advantages that:
1. the utility model uses the metal aluminum as the conductive layer of the power battery integrated busbar, thereby effectively reducing the cost of the integrated busbar and simultaneously reducing the weight of the bottom busbar;
2. the utility model discloses the terminal that power battery integrated mother arranged adopts metal nickel piece and metal aluminium to carry out the complex, carries out fixed connection through the welded mode, has guaranteed the stability of the female electrical property of arranging of power battery integration, has avoided the copper aluminium composite sheet to need electroplate and the unstable scheduling problem of performance.

The reference numbers in the figures are:
1-busbar terminal 2-metal nickel sheet
Detailed Description
The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.
As attached figure 1 the utility model discloses the power battery is integrated arranges that compound terminal structure schematic diagram is shown, the power battery of a compound terminal structure is integrated female arranges, and power battery is integrated female arranging including conducting layer and insulating layer, and multilayer conducting layer and multilayer insulating layer compound become power battery integrated female arranging. The conductive layer is made of metal aluminum. The conducting layer of the busbar extends outwards to form a terminal structure, and the terminal structure is a composite structure of metal aluminum and a metal nickel sheet 2. The shape of the metallic nickel plate 2 is identical to that of the metallic aluminum terminal 1. In this embodiment, the thickness of the metal nickel plate 2 is 0.2 mm. The composite structure of the metal aluminum and the metal nickel sheet 2 of the terminal structure is characterized in that the metal aluminum and the metal nickel sheet 2 are fixedly connected in a welding mode. The metal nickel sheet 2 is welded on the metal aluminum busbar terminal 1, and the thickness and the weight are not increased basically, so that the electrical performance of the laminated busbar of the power battery is improved, and the structure, the size and the weight of a product are not influenced.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can be covered within the protection scope of the present invention without the changes or substitutions thought by the inventive work within the technical scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
