Description of drawings
Fig. 1 is structural representation of the present utility model; (draw copper nickel line of demarcation)
Fig. 2 is the upward view of Fig. 1.
In figure: 1, anodal nickel row; 2, copper coin; 3, negative pole nickel row.
Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
see also Fig. 1 and Fig. 2, a kind of large electric current copper nickel row for the connection of power battery pack polar-plate-type battery core, comprise the anodal nickel row 1 and the negative pole nickel row 3 that connect by copper coin 2, described anodal nickel row 1, described negative pole nickel row 3 and 2 one-tenth I-shaped layouts of described copper coin, described anodal nickel row 1 has 16 solder joints that are connected with the battery core anode plate, 16 solder joints under described anodal nickel row are distributed in anodal nickel row's 1 two ends, described negative pole nickel row 3 has 14 solder joints that are connected with battery negative plate, 14 solder joints under described negative pole nickel row are distributed in negative pole nickel row 3 two ends.Anodal nickel row and negative pole nickel row all adopt the both-end Welding Structure, make the solder joint of a battery core anode plate reach 16, and the solder joint of a battery core negative plates reaches 14, has utilized fully the contact area of pole plate, and the current-carrying area is maximized.
Described anodal nickel row 1 and described negative pole nickel row's 3 bottom is provided with groove.To dodge the weld mark that stays after nickel row and welding copper bus, the groove structure of nickel row bottom is avoided weld mark well, and nickel row is fitted well with the battery core pole plate, if nickel row can not combine closely with pole plate, can cause the phenomenons such as the bad and loose contact of resistance spot welding.
Described anodal nickel row 1 and described negative pole nickel row's 3 thickness all is no more than 0.3mm.Afflux can be adjusted according to the actual requirements with the thickness of copper coin 2.
The utility model is in order to guarantee large sectional area, and large conveyance capacity, and bus-bar has adopted the dual compound group technology of copper nickel, with nickel strap as the material that connects battery core, take the material of copper coin for concentrated electric current.Nickel strap and copper coin adopt the technique of Laser Welding to weld together, and battery core pole plate and nickel strap are connected together by Resistance Welding.The single battery electric current focuses on copper coin by nickel strap, then focuses on an end by copper coin, is connected with next power brick by bolt column.Battery core and nickel row's electrical current carriers is mainly the solder joint of resistance spot welding, battery pole plates in the past and nickel row's pad is 8, negative pole is 6, and characteristics of the present utility model are the effective areas that farthest utilized pole plate, pad is expanded as respectively 16 and 14, effectively enlarged the current-carrying area, made copper nickel row realize the function of transshipping large electric current.
Although the above is described preferred embodiment of the present utility model by reference to the accompanying drawings; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away from the scope situation that the utility model aim and claim protect, can also make a lot of forms, within these all belong to protection range of the present utility model.
