The terminal piece comprises a mounting groove extending out of the terminal shell, a contact part contacted with the PCB, at least one circuitous part connected with the contact part and capable of being elastically compressed in the axial direction, and a supporting part connected with the circuitous part and used for supporting the circuitous part.
