The detection part 110 includes a detection line 110a, a detection slot 110b and a detection column 110c, the detection slot 110b is opened in the terminal 101, and each input line 103 and output line 104 is provided with one detection slot 110b, the detection slot 110b is provided with a detection line 110a, the detection line 110a is connected with the corresponding input line 103 or output line 104 below the detection slot 110b, the detection column 110c is arranged in the detection terminal 107, the length of the detection column 110c is less than the length of the bolt 108, so that the bolt 108 is inserted into the slot 105 during the process of inserting the detection column 110c into the detection slot 110b, at this time, the lower end of the bolt 108 abuts against the upper end of the copper column 106 and presses the disconnecting spring 109c downward to disconnect the circuit, the detection column 110c cooperates with the detection line 110a.

[0034] Please refer to Figures 4 to 8The application provides a connecting device for detecting a terminal, a protection assembly is arranged in the detecting terminal 107, the protection assembly comprises a switch 107b-1, a pressing groove 107b-2, a pressing block 107b-3 and a connecting part 107b-4, the pressing groove 107b-2 is arranged in the detecting terminal 107, the pressing block 107b-3 is slidably connected in the pressing groove 107b-2, the lower end of the pressing block 107b-3 is fixedly connected with the latch 108, the switch 107b-1 is slidably connected on the side wall of the detecting terminal 107, and the connecting part 107b-4 is arranged in the connecting groove 107a. The switch 107b-1 is provided with a pressing chamfer 107b-1a close to one side of the detecting terminal 107, the pressing chamfer 107b-1a is matched with the pressing block 107b-3, when the switch 107b-1 moves into the pressing groove 107b-2, the pressing chamfer 107b-1a extrudes the pressing block 107b-3, at this time, the pressing block 107b-3 moves downwards under the extrusion of the pressing chamfer 107b-1a. The connecting part 107b-4 comprises an upper connecting column 107b-4a, a connecting baffle 107b-4b, a lower connecting column 107b-4c and a connecting spring 107b-4d, the connecting baffle 107b-4b is slidably connected in the connecting groove 107a, the lower connecting column 107b-4c is fixedly arranged at the lower end of the connecting baffle 107b-4b, the connecting spring 107b-4d is in abutment with the lower end of the connecting baffle 107b-4b and the inner wall of the detecting terminal 107 respectively, the upper end of the connecting baffle 107b-4b is matched with the lower end of the pressing block 107b-3, and the upper end of the connecting baffle 107b-4b is always in abutment with the lower end of the pressing block 107b-3, the lower end of the lower connecting column 107b-4c is matched with the upper end of the detecting column 110c, when the lower end of the lower connecting column 107b-4c is in contact with the upper end of the detecting column 110c, the circuit is in communication, the upper connecting column 107b-4a is arranged at the upper end of the connecting baffle 107b-4b, the upper connecting column 107b-4a is slidably connected with the center of the protection cover 111, so that the detecting contact can extend into the protection cover 111 and be connected with the upper connecting column 107b-4a during detection. The switch 107b-1 is provided with a pull rod 107b-1b away from the detecting terminal 107.

[0035] The rest of the structure is the same as that of the embodiment 1.

[0036] Working principle: when the plug 108 is inserted into the slot 105 and presses the broken spring 109c downwards, the circuit is in the off state, at this time, the detection column 110c cooperates with the detection line 110a. Because the detection column 110c does not contact the connecting column in the normal state, it can prevent water from flowing into the terminal 101 along the detection column 110c when the operator has water in his hand, and also prevent the operator's hand from indirectly contacting the terminal 101 through the detection terminal 107. When detecting, the operator pushes the pull rod 107b-1b on the switch 107b-1 downwards into the slot 107b-2, the switch 107b-1 is provided with a downward chamfer 107b-1a on the side close to the detection terminal 107, the downward chamfer 107b-1a cooperates with the downward block 107b-3, and the downward chamfer 107b-1a will press the downward block 107b-3 when the switch 107b-1 moves. At this time, the downward block 107b-3 moves downwards under the pressure of the downward chamfer 107b-1a. Because the lower end of the downward block 107b-3 cooperates with the upper end of the connecting baffle 107b-4b, the upper end of the connecting baffle 107b-4b always abuts against the lower end of the downward block 107b-3, and the outer wall below the connecting baffle 107b-4b is provided with a connecting spring 107b-4d, the two ends of the connecting spring 107b-4d abut against the lower end of the connecting baffle 107b-4b and the inner wall of the detection terminal 107 respectively, therefore, when the downward block 107b-3 moves downwards, the connecting baffle 107b-4b will be pressed and move downwards, and the connecting spring 107b-4d will be pressed, until the lower end of the lower connecting column 107b-4c contacts the upper end of the detection column 110c, at this time, the detection terminal 107 is connected with the terminal 101, and the operator can extend the detection contact into the protective cover 111 to detect. The upper connecting column 107b-4a is arranged on the upper end of the connecting baffle 107b-4b, and the upper connecting column 107b-4a is connected with the center of the protective cover 111, which can ensure that the detection contact is connected with the upper connecting column 107b-4a when it extends into the protective cover 111.
