Description

Technical Field

[0001] The utility model relates to the technical field of electrical accessories, in particular to a wire duct for electrical installation. Background Art

[0002] With the booming development of production, work and testing industries such as factories, office buildings and laboratories, the usage and utilization rate of electrified equipment are continuously increasing, resulting in an increase in the number of wires and cables connected to production equipment, office equipment and instruments. The disorderly indoor layout of too many wires and cables not only affects the aesthetics, but is also easily damaged accidentally, posing a safety hazard, which is not conducive to the movement of relevant personnel indoors and is also inconvenient for effectively maintaining and screening designated wire bodies. Therefore, in order to regularize and protect communication wires and power supply wires, at present, wire ducts are often arranged in the laying environment to arrange and limit several wires and wrap and protect them, so as to mechanically protect and electrically protect the wires laid along the wire duct, improve the convenience of wiring, the neatness of wiring, and also facilitate the search, maintenance and replacement of designated wires.

[0003] However, when the existing wire ducts are laid, they need to be bent according to the actual indoor situation, resulting in that the groove wall edges at the corners are extremely likely to hinder the turning and pulling of the wires. The relatively sharp corner edges will hinder the pulling and passing of the wires during the wire threading process, and are also extremely likely to scratch the outer sheath of the wires. In addition, the existing integral corner wire ducts are not convenient for the passing of the wire bodies to be threaded in batches, which hinders wiring; the spliced corner wire ducts have many obvious butt gaps, resulting in poor splicing sealing and extremely easy for external water vapor to enter the groove cavity and damage the wires, posing a safety hazard. Summary of the Utility Model
