Specifically, the contact piece 15 includes a first cantilever 13 and a second cantilever 14, and the second cantilever 14 is disposed between two adjacent first cantilevers 13. Further, the ends of the first cantilever 13 and the second cantilever 14 are respectively provided with a first bending portion 12 bending upwards.
