[0048] As shown in the figure, the terminal housing 1 has a current guiding structure and resistor connector mounting groove 107 on its left, right and bottom sides.

The deformation of the nickel-titanium alloy wire 403 will drive the trigger device movable end 401 to move towards the trigger device fixed end 402. The continuous deformation of the nickel-titanium alloy wire 403 will drive the trigger device movable end 401 to disengage from the grounding contact 3.

[0052] As shown in the figure, the battery connector 12 includes a mounting plate. Battery holders 1201 are fixedly connected to both ends of the front side of the mounting plate.

The battery negative electrode guide plate 9 is fixedly connected inside the battery negative electrode guide plate mounting groove 101. By setting the battery connector 12, it can be pulled out from the terminal housing 1 for replacing the battery 11 with insufficient power.

[0053] The overall working principle of this invention is as follows:

[0054] The wire is pressed into the terminal blocks 201 at both ends of the current-conducting structure by the clamping screw 7. When the circuit is normal, the current path is as follows: the current is conducted from the wire to the current-conducting structure, flows through the terminal block 201 and the conductive plate 202, and then flows out through the other wire. Due to the presence of the resistor 5, the current does not pass through the resistor connector 6. When one side of the wire fails, the current cannot pass through the current-conducting structure 2 and then flows out through the other wire. At this time, the current path is as follows: it flows through the resistor connector 6 to the resistor 5, then from the resistor 5 to the nickel-titanium alloy wire 403 in the fixed end 402 of the trigger device, and then from the nickel-titanium alloy wire 403 to the movable end 401 of the trigger device. At this time, the movable end 401 of the trigger device is conductive with the grounding contact 3. The current flows through the grounding contact 3 to the grounding busbar 15 to form a circuit. After the circuit is formed, the nickel-titanium alloy wire 403 will deform due to the current. The deformation of the nickel-titanium alloy wire 403 will drive the trigger device to move. When end 401 moves toward the fixed end 402 of the trigger device, the continuous deformation of the nickel-titanium alloy wire 403 will cause the movable end 401 of the trigger device to disconnect from the grounding contact 3, thus breaking the current circuit. At the same time, the movement of the movable end 401 of the trigger device will cause the trigger switch 13 fixed thereon to move, causing the copper sheet 1301 on the trigger switch 13 to come into contact with the negative electrode current guide plate 14 and the negative electrode current guide bus 9 of the battery. At this time, the circuit of the battery 11 is turned on, and the current flows out from the positive terminal of the battery 11, through the positive electrode current guide contact 10 of the battery, through the positive terminal of the LED 8, and then through the negative terminal of the LED 8. After flowing out through the negative terminal of the LED 8, it flows through the negative electrode current guide bus 9 and through the copper sheet 1301 to the negative electrode current guide plate 14 of the battery, and finally flows back to the negative terminal of the battery 11. At this time, the LED 8 emits light. When the fault is resolved, the operator can manually reset the circuit of the battery 11 by toggling the trigger switch 13, so that the LED 8 stops emitting light.
