Claim 0:
1. A power supply with a replaceable communication module, comprising:
a casing, comprising a port;
a main board, disposed in the casing and provided with a power conversion circuit, the power conversion circuit comprising at least one electrical connection terminal, wherein the main board comprises at least one assembling hole;
a sub-board, disposed on the main board, the sub-board comprising at least one first connector and a second circuit board, wherein the second circuit board is provided with the at least one first connector on one side and is electrically connected with the power conversion circuit of the main board, a first interface of each of the at least one first connector directly facing the port, wherein the sub-board further comprises
a socket disposed on the side of the second circuit board with the at least one first connector, and the socket and the second circuit board are arranged in an extending direction, and wherein the socket comprises at least one positioning protrusion, two side walls disposed in parallel, two position limiting rails respectively located on the two side walls, and a retaining wall, and wherein the retaining wall is disposed on a side of the socket facing the second circuit board, and the two side walls are respectively located on two opposite sides of the socket without the retaining wall and connected to the retaining wall, and the at least one positioning protrusion is formed on one of the two side walls and assembled in the at least one assembling hole of the main board; and
the replaceable communication module, receiving on and off signals of at least one external electronic device to exchange information therewith, and the replaceable communication module comprising a first circuit board and a communication circuit disposed on the first circuit board, the communication circuit comprising a second connector for forming an electrical connection with the at least one external electronic device, the first circuit board comprising an electrical connection part electrically connected to the communication circuit, wherein the replaceable communication module is assembled in the socket, and two sides of the first circuit board are respectively connected with the two side walls, an assembly position of the first circuit board in the socket is limited by the retaining wall, and the first circuit board is guided by the two position limiting rails so that the replaceable communication module is displaced relative to the socket to form a first state and a second state of the electrical connection part, wherein in the first state, the electrical connection part connects with the first interface, and the replaceable communication module is electrically connected to the power conversion circuit via the sub-board, and in the second state, the electrical connection part detaches from the first interface, and the replaceable communication module is separated from the sub-board and electrically disconnected from the sub-board.
