[0016] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0018] See also Figure 1 As shown, the utility model is an integrated welding terminal, which consists of an integrally formed base 1 and a column 10, and the two are matched to form a "convex" shape. A mounting hole 14 recessed into the column 10 is provided on the other side of the base 1. When in use, the column 10 is controlled to be inserted into the battery lead column in a molten state to install the welding terminal.

[0019] Solder terminals are available in brass, aluminum or stainless steel.

[0020] In order to facilitate better connection between the column 10 and the lead column and improve the bonding strength of the connection, the technical solution increases the contact area between the column 10 and the lead liquid during installation. The column 10 provided in this application is a polygonal structure, or when a cylindrical structure is adopted, several open grooves 13 are opened on its outer side wall.

[0021] Based on the above, when the column 10 adopts a cylindrical structure, the column 10 includes a first column 11 and a second column 12 formed in one piece, and the first column 11 is located between the second column 12 and the base 1 .

[0022] Specifically, the size of the first column 11 is larger than that of the second column 12 , and the outer diameters of the first column 11 and the second column 12 differ by 2 mm. Meanwhile, the first column 11 and the second column 12 are concentrically arranged.

[0023] like Figure 2 , the column 10 is a twenty-four prism.
