Description

Technical Field

[0001] This utility model relates to the field of cable installation technology, specifically to a cable tray connection device. Background Technology

[0002] Cable trays are devices used to protect cables. They come in various structures, including trough, tray, ladder, and mesh types, and consist of supports, brackets, and installation accessories. Based on manufacturing materials, cable trays can be categorized into five main types: steel, aluminum alloy, stainless steel, fiberglass, and flame-retardant. Cable trays offer advantages such as lightweight construction, high strength, low cost, easy construction, flexible wiring, precise installation, and aesthetically pleasing appearance. They also facilitate future technical improvements, cable expansion, and maintenance. However, when multiple cables are connected in a single unit, later cable expansion requires disassembling the original tray to install additional cables. The screws on the cable tray corrode after prolonged exposure to rainwater, increasing the difficulty of disassembly. Utility Model Content
