Referring to the first and second figures, the plurality of conductive terminals 2 are partially received in the receiving slots 10 of the insulative housing 1 . Referring to the third to fifth figures, the conductive terminal 2 includes a contact portion 21 electrically contacting the battery mating connector (not shown) and protruding from the insulative housing 1 and a tail portion held by the insulative housing 1 22 and a serpentine elastic portion 23 connecting the contact portion 21 and the tail portion 22. The contact portion 21 protrudes from the front end surface 14 of the insulative housing 1 . The contact portion 21 has a U-shaped structure, and one end of the contact portion 21 is bent to extend out of a free portion 210. The free portion 210 is bent downward and adjacent to the lower surface 13 of the insulative housing 1. The free portion 210 includes a pair of convex walls 211 and a support portion 212. The pair of convex walls 211 are located on both sides of the free portion 210 and are bent inwardly. The support portion 212 has a "T" shape and is located at the free end of the free portion 210. The contact portion 21 further includes a convex portion 213 disposed along the extending direction of the contact portion 21, and the convex portion 213 defines a contact point electrically contacting the battery docking connector (not shown). The tail portion 22 has a U-like structure and abuts the upper surface 12 and the lower surface 13 , and the tail portion 22 is located at the tail end of the accommodating groove 10 . Both ends of the tail portion 22 are bent and extended to extend from the holding portion 221 and the soldering piece 224. The holding portion 221 is adjacent to the upper surface 12 . The solder tab 224 is adjacent to the lower surface 13. The holding portion 221 includes a barb 222 and a retaining portion 223 . The barbs 222 are located on both sides of the holding portion 221 . The anti-retraction portion 223 is tear-formed on the surface of the holding portion 221 and cooperates with the positioning groove 11 of the insulative housing 1 . The soldering piece 224 is exposed at the tail end of the accommodating groove 10 to be electrically connected to a circuit board (not shown). The serpentine elastic portion 23 is located in the accommodating groove 10 . The serpentine elastic portion 23 includes a bent portion 231 and a connecting portion 232 that connects the two bent portions 231. The vertical length of the section of the bent portion 231 is greater than the vertical length of the section of the connecting portion 232.
