[0012] Beneficial effects:

[0013] 1. The protective component for the wire of the junction box can form a closed space by cooperating with the block that can effectively clamp the wire through the wire connecting tube, thereby shielding the influence of dust and other debris in the external environment.

[0014] 2. The protective component for the wires of the junction box limits the position of the block by means of a limit rod and can regulate the moving path of the block.

[0015] 3. The protective component for the wire of the junction box cooperates with the adjustment slot through the fixed block. During the movement of the adjustment slot, a force is applied to the outside of the fixed block to drive the fixed block to move, so that the blocks are close to each other to clamp the wire.

[0016] 4. The protective component for the wiring of the junction box detects the external gas concentration through the gas detector and transmits the data to the remote terminal, which analyzes in real time whether the concentration of hazardous gas and combustible gas in the site exceeds the critical value.
