A lower groove 121 corresponding to the upper groove 111 is defined on the upper surface of the lower substrate 12 . A step portion 143 protrudes upward from the left and right ends of the lower base plate 12 at a certain distance from the support arm 14 . A receiving groove 131 extending up and down is defined on the front surface of the connecting portion 13 , and the receiving groove 131 communicates with the corresponding upper groove 111 and lower groove 121 . The intersection of the inner surface of the support arm 14 and the connecting portion 13 protrudes in a shape of Shaped stopper 142. An insertion hole 141 parallel to the lower groove 121 is formed between the bottom surface of the block 142 , the outer surface of the stepped portion 143 and the inner surface of the support arm 14 , and the insertion hole 141 passes through the connecting portion 13 .

Please refer to FIG. 1 and FIG. 2 , the conductive terminal 2 has a base 21 . The base 21 is accommodated in the receiving groove 131 of the connecting portion 13 of the insulating base 1 , and a pivot arm 22 and a connecting arm 23 respectively extend substantially vertically forward from the upper end and the lower end of the base 21 . The rear end of the pivot arm 22 is received in the upper groove 111 of the upper base 11 . The front end of the pivot arm 22 is bent upward and then bent forward and downward to form an arc-shaped pivot portion 221 , and the pivot portion 221 protrudes from the upper groove 111 to the front edge of the upper substrate 11 . The connecting arm 23 is accommodated in the lower groove 121 of the lower substrate 12 of the insulating base 1 . A solder tail 24 extends backward from the lower end of the base 21 , and the solder tail 24 is soldered on a circuit board (not shown in the figure).
