Abstract
The utility model relates to a connecting element for a large-current round lithium ion battery pack, which is characterized in that the connecting element comprises a punching forming nickel sheet, wherein the punching forming nickel sheet is placed on round batteries in regular arrangement, each forming nickel sheet positioning hole uniformly arranged on the forming nickel sheet at intervals respectively correspond to a positive electrode and a negative electrode of electric cores of the round batteries, projected parts of the forming nickel sheets arranged on the forming nickel sheet are correspondingly arranged in gaps formed by arrangement of the round batteries, the forming nickel sheet and resistors of the round electric cores are welded and connected, in addition, projected parts of copper sheets mainly carrying the current are inserted into round holes of the corresponding forming nickel sheets, and the projected parts of the copper sheets and the round hole of the forming nickel sheets are connected through interference fit, so the tight contact between the copper sheets and the forming nickel sheets can be ensured, the improvement on the current bearing capability on the current of the electric core group through the copper sheets can be ensured, at the same time, the copper sheets and the round holes on the forming nickel sheets are communicated after the combination, and good heat radiation effect can be obtained.
Description
Technical field
The utility model relates to a kind of lithium ion battery group connector, the particularly a kind of circular lithium ion battery group of big electric current connector that is used for.
Background technology
At present, because lithium ion battery has the voltage height, capacity is big, volume is little, light weight, advantages such as operating temperature range is wide, the lithium ion battery group has been widely used in every field, especially be applied to fields such as electric automobile, electric bicycle, electric tool, yet the selection of the assembling mode of high voltage, high power capacity and super-high-current connector has become a bottleneck of restriction high voltage, high power capacity, the development of great current cell group.Therefore, determining of the exploitation of big electric current connector and particular combinations mode become the task of top priority.Because some lithium ion battery groups not only require high voltage, high power capacity, but also require battery pack when work, can lead to sizable electric current, as the continuous firing electric current is 80A, 120A etc., and the connection in series-parallel combination to circular lithium ion battery group is to be connected by 0.15mm or the thick nickel strap of 0.2mm mostly in producing at present, and that nickel strap bears the ability of electric current is very limited, the ability that can not bear 80A or higher electric current.
Therefore, provide a kind of simple in structure, reasonable in design, to use the easy circular lithium ion battery group of the big electric current connector that is used for be one of these those skilled in the art problem that should address.
The utility model content
The purpose of this utility model is to overcome above-mentioned weak point, provide a kind of simple in structure, use the easy circular lithium ion battery group of the big electric current connector that is used for.
The technical scheme that the utility model adopted is for achieving the above object: a kind of circular lithium ion battery group of big electric current connector that is used for, it is characterized in that comprising punch forming nickel sheet, described moulding nickel sheet places above the regularly arranged circular batteries, each moulding nickel sheet location hole that evenly is provided with at interval on the moulding nickel sheet is the negative or positive electrode of corresponding circular battery battery core respectively, the moulding nickel sheet projection correspondence that moulding nickel sheet is provided with is in the middle of the space of circular batteries between arranging, and described moulding nickel sheet is connected with circular electric core resistance welded; And the projection of the copper sheet of main loaded current inserts in the circular hole of corresponding moulding nickel sheet, and the projection of described copper sheet is connected for interference fit with the circular hole of moulding nickel sheet; The copper sheet circular hole that is respectively equipped with on copper sheet after the combination and the moulding nickel sheet communicates with moulding nickel sheet circular hole.
The beneficial effects of the utility model are: the utility model is by the big electric current connector and the compound mode of two kinds of compound exploitations of material, thoroughly solve big electric current connector and selected difficulty, problem of difficult processing, effectively improve the conveyance capacity that connects, and assembly and disassembly are very convenient in battery combination.It is simple in structure, and is reasonable in design, uses easy.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: 1 copper sheet, 2 copper sheet circular holes, the projection of 3 copper sheets, 4 moulding nickel sheets, 5 moulding nickel sheet circular holes, 6 moulding nickel sheet location holes, 7 moulding nickel sheet projections, 8 circular electric cores.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, details are as follows to embodiment, structure, feature that foundation the utility model provides:
As shown in Figure 1, a kind of circular lithium ion battery group of big electric current connector that is used for, it is characterized in that comprising punch forming nickel sheet 4, described moulding nickel sheet 4 places above the regularly arranged circular batteries, each moulding nickel sheet location hole 6 that evenly is provided with at interval on the nickel sheet is the negative or positive electrode of corresponding circular battery battery core 8 respectively, moulding nickel sheet projection 7 correspondences that the nickel sheet is provided with are in the middle of the space of circular batteries between arranging, and described moulding nickel sheet 4 is connected with circular electric core 8 resistance welded; And the projection 3 of the copper sheet of main loaded current inserts in the circular hole 5 of corresponding moulding nickel sheet 4, and both are connected the circular hole of the projection 3 of described copper sheet 1 and moulding nickel sheet 45 for interference fit; The copper sheet circular hole 2 that is respectively equipped with on copper sheet 1 after the combination and the moulding nickel sheet 4 communicates with moulding nickel sheet circular hole 5.
The concrete making: with 0.15mm or the thick nickel strap of 0.2mm, strike out moulding nickel sheet 4 as shown in Figure 1, (as model is 18650 with circular batteries, 26700 etc.) regularly arranged, moulding nickel sheet 4 is placed on above the good battery of arrangement, the negative or positive electrode of each the moulding nickel sheet location hole 6 corresponding electric core 8 of circle on the nickel sheet, 7 of projections on the nickel sheet should be in the middle of the space of circular batteries between arranging, with electric resistance welding moulding nickel sheet 4 and circular electric core 8 are welded then, projection 3 with the copper sheet 1 of main loaded current inserts in the hole of corresponding moulding nickel sheet 4 at last, connect by being full of to cooperate between the hole of the projection 3 of copper sheet and moulding nickel sheet 4, so both guaranteed tight contact of copper sheet 1 with moulding nickel sheet 4, guarantee that again the electric current of electric core group can improve the ability of loaded current by copper sheet 1, circular hole 2 on the copper sheet 1 and the circular hole 5 on the moulding nickel sheet 4 communicate after combination simultaneously, can play good thermolysis again.By the assembling of this kind connected mode, convenient disassembly, reliability height.
Above-mentionedly with reference to embodiment this being used for the detailed description that the circular lithium ion battery group of big electric current connector carries out, is illustrative rather than determinate; Therefore in the variation and the modification that do not break away under the utility model general plotting, should belong within the protection range of the present utility model.
