[0020]

Referring to the second to fourth figures, the conductive terminal 20 can be assembled on the above-mentioned insulating body 10, and can also be used on other types of battery connectors. The conductive terminal 20 is formed by punching a metal sheet through a planar blank (as shown in the third figure) and then undergoing a bending process. In the third figure, each part of the conductive terminal 20 will be described using the same reference numerals and names as those after the bending process. The conductive terminal 20 includes a fixing portion 21, an elastic portion 22 connected to the front side of the fixing portion 21, an abutting portion 23 connected to the front of the elastic portion 22, and a welded portion 24 connected to the rear of the fixing portion 21.

Therefore, in the present case, the lateral connecting arms 222 and the oblique connecting arms 223 at both ends of the bending arm 221 are designed such that the distance d1 outside the bending arm 221 is greater than the distance d2 inside the bending arm 221, thereby being in the elastic portion. 22 has a larger amount of deformation when contracted. The abutting portion 23 is bent back on the side of the bending arm 221. The welded portion 24 is horizontally extended after being bent back on the side of the bending arm 221. The conductive terminal 20 is formed by punching a sheet metal through a flat blank and then undergoing a bending process. The process is simple, the mold production stability is high, and the positive force provided by the elastic portion 22 is stable.
