Further in order to increase the stability of welding, the boss b is of a tapered square structure and comprises a bottom surface b1 attached to the welding surface a and an outer wall surface b2 facing away from the bottom surface b1, the area of the bottom surface b1 is smaller than that of the outer wall surface b2, so that the boss b is of a conical structure integrally facing the welding surface a, after welding, the welding material is filled around the boss b, the welding material is matched with the side waist of the boss b to form a shape, so that the conductive block body 1 cannot be separated from the welding material (as shown in figure 5), the fastening performance of the welding material and the conductive block body 1 is improved, the other side of the welding material is welded with the conductive plate end 2, the conductive block body 1 and the conductive plate end 2 are welded into a whole, after the lug boss b with the square structure is formed with the welding material, can effectively prevent conducting block body 1's rotation for circular structure, improve conducting block body 1 welding stability. The outer wall surface b2 is parallel to the joint line of the first conductive block 11 and the second conductive block 12, and is used for limiting the integral flatness of the conductive block body 1 and improving the welding accuracy by attaching the outer wall surface b2 to the surface of the conductive plate end 2 when the conductive block body 1 is welded to the conductive plate end 2. The distances from each edge of the bottom surface b1 to the edge of the welding surface a are equal, so that the edges of the welding surface a in all directions are welded to the same degree, and the welding balance of the welding surface a is improved.

Further in order to improve the stability of welding to conducting block body 1, because during the welding, there is the contact gap between welding material can and the side waist of boss b, can have certain galvanic corrosion after long-time circular telegram for this contact gap increase influences the stability of conducting block body 1, consequently around opening on the side waist of boss b and being equipped with annular b3, this annular b3 can store partial welding material, can further prescribe a limit to the position of conducting block body 1, improves its stability.

Further, in order to improve the firmness between the welding material and the conducting plate end 2, a groove b4 which is smaller than the area of the bottom b1 is formed in the center of the outer wall surface b2 towards the welding surface a, the depth of the groove b4 is equal to the thickness of the boss b, an opening which extends to the edge of the bottom b1 is formed in one side of the groove b4, the groove b4 can be used for increasing more welding materials on the original basis and contacting with the conducting plate end 2 (as shown in fig. 5), the contact area between the welding materials and the conducting plate end 2 is increased, and the welding tightness between the conducting block body 1 and the conducting plate end 2 is further integrally increased.
