[0029] When the circuit board body 3 is connected to the leakage protection module 1, one end of the circuit board body 3 is inserted into the mounting port 205. When the circuit board body 3 contacts the positioning pin 209, as the circuit board body 3 moves, the circuit board body 3 drives the positioning pin 209 to move in the receiving groove 203 and compresses the reset spring 210. After the circuit board body 3 is fully inserted into the mounting port 205, the reset spring 210 inserts the positioning pin 209 into the positioning groove 206 and automatically positions the connection between the circuit board body 3 and the leakage protection module 1.
