Technical Field
The utility model relates to a lithium cell technical field especially involves a novel nickel piece that welding effect is good.
Background
In recent years, cylindrical lithium batteries are widely applied, such as 18650 lithium batteries and 21700 lithium batteries, pack battery packs formed by series-parallel connection of the cylindrical lithium batteries can be applied to various fields, most of the series-parallel connection structure industry adopts nickel sheets, the nickel material has the advantages of good conductivity coefficient, easiness in processing and the like, the nickel sheets and the lithium batteries are welded together by spot welding to form a series-parallel connection battery pack structure, and the reasonable design of the nickel sheets is beneficial to saving the internal space of the lithium battery pack, improving the welding effect and improving the conductivity. The traditional battery nickel sheet is inconvenient to position, and the conditions of insufficient soldering and infirm soldering are easy to occur.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the weak point among the above-mentioned prior art and provide a welding is stable, the convenient novel nickel piece that welds respond well of location.
The utility model discloses a realize through following mode:
the utility model provides a novel nickel piece that welding effect is good which characterized in that: comprises a nickel sheet body; the nickel sheet body is provided with a plurality of sunken welding surfaces; a cross-shaped splitter box is arranged in the welding surface; downward convex welding spots are arranged between two adjacent slotted holes of the cross-shaped shunt slot; and a connecting sheet is arranged on one side of the nickel sheet body.
Furthermore, the sinking depth of the welding surface is more than or equal to 0.4 mm.
Further, the welding surface is circular.
Furthermore, the nickel sheet body is provided with a positioning hole.
Furthermore, an arc buffer area is arranged at the joint of the connecting sheet and the nickel sheet body.
The beneficial effects of the utility model reside in that: the welding surface and the battery bracket are naturally positioned through the sunken welding surface structure, so that the nickel sheet can be quickly aligned with the battery bracket at the basic position, the attaching degree of the nickel sheet to the battery is increased, and the nickel sheet is accurately positioned through the positioning hole; the cross-shaped splitter box and four large protruding welding spots which are uniformly distributed in the circumferential direction greatly improve the spot welding effect and the electric conduction capability, and ensure the welding stability.
