Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection range of the present utility model is made more explicit defining.
See also Fig. 1 to Fig. 3, the utility model provides a kind of cell connector 1, comprise the first sheet metal 2 and the second sheet metal 6, described the first sheet metal 2 comprises a plurality of the first through holes 3 and lug 4, described lug 4 is arranged on a lateral edges of described the first sheet metal 2, described the second sheet metal 6 comprises a plurality of the second through holes 7, and described a plurality of the first through hole 3 and described a plurality of the second through hole 7 difference correspondences.
The first sheet metal 2 is copper sheet described in the utility model, and described the second sheet metal 6 is the nickel sheet, the most electric current of described the first sheet metal 2 carryings, and described the second sheet metal 6 carries another part electric current as the transition of the first sheet metal 2 and battery battery core.
The first through hole 3 is rectangular opening described in the utility model, described the second through hole 7 is irregularly-shaped hole, described the second through hole 7 can improve the welding performance between described the second sheet metal 6 and the battery battery core, improves the utilization ratio of electric current in the welding process, occurs the situation of rosin joint in avoiding welding.
The first sheet metal 2 described in the utility model and described the second sheet metal 6 form integrative-structure by laser welding.
Lug described in the utility model 4 comprises two connecting holes 5, guarantees the reliability and stability that connect.
The area of the first sheet metal 2 described in the utility model is greater than the area of described the second sheet metal 6, and after described the first sheet metal 2 and described the second sheet metal 6 laser welding, the lug 4 of described the first sheet metal 2 is not covered by described the second sheet metal 6.
In sum, the cell connector 1 that the utility model discloses, quantitative requirement according to the single battery of series, parallel, beat the hole of respective numbers at described the first sheet metal 2 and described the second sheet metal 6, cell connector 1 has solved the excessive problem of electric current in the battery pack, and firm welding reduces production costs, manufacturing process is ripe, can realize producing in enormous quantities.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
