The limiting member 120 may have a block structure, and the limiting member 120 protrudes from the groove wall of the mounting groove 11, and the limiting member 120 may also have a plate structure and protrudes from the groove wall of the mounting groove 11.

In addition, by providing the fixing posts 13, the fixing posts 13 are equivalent to fixing the circuit board 20 in a direction parallel to the first surface 201 of the circuit board 20, and the fastening portion 12 is equivalent to blocking the circuit board 20 in a thickness direction of the circuit board 20, so that the fastening portion 12 and the fixing posts 13 are used simultaneously, and the circuit board 20 can be fixed in the mounting groove 11 more firmly.

Through such a setting, when installing the circuit board 20 in the mounting groove 11, the notch 204 on the side 203 of the circuit board 20 can be used to enable the fixing post 13 to be embedded into the fixing groove 21, that is, during the process of installing the circuit board 20, the notch 204 on the side 203 of the circuit board 20 is equivalent to be used as an introducing port, once the circuit board 20 enters the mounting groove 11, the introducing port can be opposite to the fixing post 13, so that the circuit board 20 enters the fixing groove 21 through the introducing port during the moving process, and the fixing post 13 is matched with the fixing groove 21, so that the circuit board 20 can be limited and fixed, and the problem that the circuit board 20 is easy to shake in the mounting groove 11 is avoided.

In addition, the interface 40 is disposed on the second surface 202 of the circuit board 20, so that once the interface 40 is connected to the charging cord, when charging or transmitting data through the charging cord, electrical energy or data can be transferred to the circuit board 20, and the circuit board 20 can continue transferring electrical energy or data, so that the electronic device can be charged or transmitting data.
