Abstract
The utility model discloses a storage battery terminal with a high-intensity structure. The storage battery terminal with the high-intensity structure comprises a copper core and a copper sheet, wherein the outer periphery surface of the copper core is provided with a first concave step and a second concave step from top to bottom; the copper sheet is provided with a hole matched with the external diameter of the second concave step of the copper core; the upper surface of the copper sheet is vertically fit with the external diameter surface of the first concave step; the fitting position is provided with a first rivet weld point; the lower surface of the copper sheet is vertically fit with the external diameter surface of the second concave step; and the fitting position is provided with a second rivet weld point. According to the storage battery terminal with the high-intensity structure, which is disclosed by the utility model, the copper core and the copper sheet with the double-step structure are matched to form an upper and lower double-surface rivet weld structure, a double insurance effect is realized, the twisting force strength of the copper core terminal is effectively guaranteed, and the quality of batteries is guaranteed.
Description
Technical field
The utility model relates to the storage battery field, is specifically related to a kind of high-strength structure accumulator terminal.
Background technology
Accumulator terminal is the vitals of battery, battery terminal and inside battery ways of connecting have a variety of, the most common is that the copper core is cast in lead base, this connected mode is simple, but production technology is handled complicated, it is a lot of to influence the loosening factor of copper core and lead base, control etc. as the temperature of copper wicking surface coating material, copper wicking surface flux application, the casting of copper core, and all be the factor that influences copper core and lead base combination.Also having a kind of common connected mode at present is that copper core and copper sheet rivet welding are in the same place, this mode production mechanization degree height, welding is reliable, copper core bonding strength is good, but the single face rivet welding is all adopted in welding, if the too thin easy generation rosin joint of solder side, terminal easily generates heat in the use, occurred the phenomenon that the client twists the copper core simultaneously, it is imperative therefore to develop a kind of high strength Welding Structure copper core.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of high-strength structure accumulator terminal, adopt the copper core of double step structure to match with copper sheet, form two-sided rivet welding structure up and down, played the effect of dual fail-safe, effectively guarantee the torsion strength of copper core terminal, guaranteed the quality of battery.
The utility model is achieved through the following technical solutions:
A kind of high-strength structure accumulator terminal, comprise copper core and copper sheet, described copper core outer peripheral face arranges the first concave station rank and the second concave station rank from top to bottom, described copper sheet is provided with the hole of matching with the second concave station rank external diameter of copper core, diametric plane is vertical outside copper sheet upper surface and the first concave station rank fits, the joint place is provided with first rivet welding point, and diametric plane is vertical outside copper sheet lower surface and the second concave station rank fits, and the joint place is provided with second rivet welding point.
The further improvement project of the utility model is, the described first concave station rank external diameter is less than its upper end external diameter 2-3mm, and the second concave station rank external diameter is less than the first concave station rank external diameter 1-2mm.
The utility model further improvement project is that the described first rivet welding point and the second rivet welding point round around the joint place respectively.
The utility model compared with prior art has following obvious advantage:
The utility model adopts the copper core of double step structure to match with copper sheet, forms two-sided rivet welding structure up and down, has played the effect of dual fail-safe, has effectively guaranteed the torsion strength of copper core terminal, guarantees the quality of battery.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, the utility model comprises copper core 1 and copper sheet 2, described copper core 1 outer peripheral face arranges the first concave station rank 11 and the second concave station rank 12 from top to bottom, described copper sheet 2 is provided with the hole 21 of matching with the second concave station rank, 12 external diameters of copper core 1, outer diametric plane is vertical copper sheet 2 upper surfaces and the first concave station rank 11 fits, the joint place is provided with the first rivet welding point 13, and outer diametric plane is vertical copper sheet 2 lower surfaces and the second concave station rank 12 fits, and the joint place is provided with the second rivet welding point 14.
The described first concave station rank 11 external diameters are less than its upper end 15 external diameter 2-3mm, and the second concave station rank, 12 external diameters are less than the first concave station rank, 11 external diameter 1-2mm.
