After using the product, wiring is convenient, the wiring is neat, the installation is reliable, and it is convenient to search, maintain, and replace the circuit.

[0003] The existing wire duct mainly includes a "U"-shaped chassis and a cover covering the "U"-shaped chassis. Ventilation slots are arranged at equal intervals on both sides of the "U"-shaped chassis, which can increase the heat dissipation capacity of the wire duct. However, in the long run, oil stains, dust, etc. generated during the operation of the electrical cabinet will enter the inner wall of the "U"-shaped chassis along the ventilation slots, and the oil stains, dust, etc. will directly adhere to the wire harness on the "U"-shaped chassis, which will cause the heat of the wire harness to not be dissipated in time, resulting in overheating of the wire harness and increasing the fire risk. Content of the Utility Model

[0004] Aiming at the deficiencies in the background art, the utility model provides a dust-proof wire duct for an electrical cabinet.

[0005] The technical solution adopted by the utility model is: a dust-proof wire duct for an electrical cabinet, including a "U"-shaped chassis and a cover covering the "U"-shaped chassis. A plurality of first ventilation slots are arranged at intervals on both sides of the "U"-shaped chassis. Dust-proof plates are arranged on both sides of the "U"-shaped chassis. A plurality of second ventilation slots are arranged at intervals on the dust-proof plates. The first ventilation slots and the second ventilation slots are arranged in a staggered manner. A dust discharge groove is formed between the dust-proof plate and the side wall of the "U"-shaped chassis.

[0006] Further: The first ventilation slots are located below the "U"-shaped chassis, and the second ventilation slots are located above the dust-proof plates.

[0007] Further: Both the first ventilation slots and the second ventilation slots are rectangular strip structures.

[0008] Further: The length and / or width of the first ventilation slots is greater than the length and / or width of the second ventilation slots.

[0009] Further: A plurality of mounting holes are arranged at intervals at the bottom of the "U"-shaped chassis.

[0010] Further: First connecting hooks are arranged on the opening of the "U"-shaped chassis in an inwardly inclined manner, and second connecting hooks adapted to the first connecting hooks are arranged on the cover.
