The L-shaped plate includes a vertical plate with a vertical length direction, the lower side of the vertical plate is connected to the manganese copper plate, and the upper sides of the two vertical plates are connected to horizontal plates extending away from each other to the left and right directions. The first copper plate includes a first part and a second part connected to the left and right, the rear sides of the first part and the second part are flush, the thickness of the first part is less than the thickness of the second part, and a notch is provided on the upper side of the second part corresponding to the connection with the first part along the front-to-back direction.

[0005] For the purpose of simple explanation, the shunt with high welding stability described in the present invention is referred to as the shunt below.

[0006] Advantages of this shunt: This shunt is used for: intelligent circuit breakers, power supplies, disconnect switches and test instruments. The terminal of this shunt adopts an L-shaped plate structure, and the thickness of the L-shaped plate along the front and back directions is less than the thickness of the manganese copper plate. The wire is welded to the transverse plate of the L-shaped plate. Compared with the columnar terminal of the existing shunt, the welding area is increased, and the welding strength and stability of the wire and the terminal are significantly increased. Moreover, since the thickness of the L-shaped plate is smaller than that of the columnar terminal, during welding, the current will concentrate heat at the welding position, which reduces the conduction speed to the entire shunt body, and can improve the welding efficiency. The thickness of the first part of the first copper plate is less than the thickness of the second part, and the rear sides of the first and second parts are flush, so that the front side of the first copper plate will form a step at the junction of the first and second parts. This step can play a role in auxiliary positioning when welding other components, and can effectively improve the stability and accuracy of welding. The design of the notch can slightly isolate the first part of the first copper plate from the shunt body, which is conducive to welding. BRIEF DESCRIPTION OF THE DRAWINGS
