[0039] In some embodiments of this utility model, the insulating post 24 extends along the axial direction of the conductive post 203 of the first row of bodies 201, and an insulating cavity 25 is formed within the insulating post 24. The conductive post 203 of the first row of bodies 201 is adapted to extend into the insulating cavity 25. It can be understood that by providing the insulating post 24 on the second cover 13, and forming the insulating cavity 25 within the insulating post 24, the conductive post 203 of the first row of bodies 201 can extend into the insulating cavity 25, further enhancing the electrical isolation and physical protection performance. This not only improves the overall safety but also ensures the reliability and stability of the connection.
