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 the present invention is as follows:
[0054] The wire is pressed by the clamping screw 7 into the terminal block 201 at both ends of the guide structure. When the circuit is normal, the current path is: conducted from the wire to the guide structure, flows through the terminal block 201 and the conductive plate 202, and then flows out through the wire on the other side. Due to the existence of the resistor 5, the current does not pass through the resistor connector 6. When a fault occurs in the wire on one side, the current cannot pass through the guide structure 2 and then flows out through the wire on the other side. At this time, the current path is: flows through the resistor connector 6 to the resistor 5, and then flows from the resistor 5 to the nickel-titanium alloy wire 403 in the fixed end 402 of the trigger device, and then flows 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 to the grounding contact 3, and the current flows through the grounding contact 3 to the grounding bar 15 to form a path. After the path is formed, the nickel-titanium alloy wire 403 will be deformed due to the current passing through it, and the deformation of the nickel-titanium alloy wire 403 will drive the trigger device to move. The end 401 moves toward the fixed end 402 of the trigger device, and the continuous deformation of the nickel-titanium alloy wire 403 will drive the movable end 401 of the trigger device to separate from the ground contact 3. At this time, the current loop is disconnected. At the same time, due to the movement of the movable end 401 of the trigger device, the trigger switch 13 fixed thereon is driven to move, causing the copper sheet 1301 on the trigger switch 13 to fit with the battery negative electrode guide plate 14 and the battery negative electrode guide bar 9. At this time, the battery 11 circuit is connected, and the current flows out from the positive electrode of the battery 11, passes through the battery positive electrode guide contact 10, passes through the positive electrode of the light-emitting diode 8, flows out through the negative electrode of the light-emitting diode 8, passes through the battery negative electrode guide bar 9, flows through the copper sheet 1301 to the battery negative electrode guide plate 14, and finally flows back to the negative electrode of the battery 11. At this time, the light-emitting diode 8 emits light. When the fault handling is completed, the operator can manually reset it by toggling the trigger switch 13, disconnecting the circuit of the battery 11, and stopping the light-emitting diode 8 from emitting light.
