[0006] Furthermore, the clamping portion, the bending portion and the welding portion are made of pure nickel material.

[0007] Furthermore, the clamping portion, the bending portion and the welding portion are integrally formed.

[0008] A circuit board comprises a circuit board body and a connecting terminal fixed on the circuit board body, wherein the connecting terminal adopts the above-mentioned nickel sheet connecting terminal, and the circuit board body has a conductive socket which is plugged with the pin and snapped with the buckle, and the pin is plugged with the conductive socket and fixed by welding.

[0009] The beneficial effects of adopting the above technical solution are:

[0010] 1. By setting the bending part to absorb or disperse the stress caused by battery vibration and shaking, the damage of the welding point between the welding part and the battery is reduced, and the risk of terminal breakage is reduced.

[0011] 2. By setting the avoidance holes, when installing the connection terminals to the circuit board, some existing electronic components on the circuit board can pass through the avoidance holes to solve the problem of normal installation.

[0012] 3. By setting the buckle, not only the firmness of the connection between the connection terminal and the circuit board is increased, but also the contact area with the conductive socket is increased, thereby increasing the stability of the electrical connection.

[0013] 4. When using nickel sheet connection terminals to connect batteries, an oxide film will naturally form on the surface of the nickel. This oxide film can improve the corrosion resistance, durability, oxidation resistance and conductivity of the connector. BRIEF DESCRIPTION OF THE DRAWINGS
