The tee joint 3 is disposed at the docking port 111, and the first end of the tee joint 3 is connected to the main tray 1. The transfer tray 2 is connected to the second end of the tee joint 3. In the present utility model, the tee joint 3 is provided to connect the main tray 1 and the transfer tray 2. The first end of the tee joint 3 is docked with the docking port 111 on the first side plate 11. Specifically, the first end of the tee joint 3 is connected to the first side plates 11 located on both sides of the docking port 111, and the second end of the tee joint 3 is docked with the transfer tray 2. In this way, the main tray 1 and the transfer tray 2 can be quickly connected through the tee joint 3, realizing the rapid assembly of the cable tray, avoiding problems such as cumbersome operation, low installation efficiency, and heavy installation burden caused by on-site cutting and welding, and also avoiding protrusions and burrs generated by on-site cutting and welding.

In this embodiment, the two arc-shaped side plates 31 are symmetrically arranged on the tee bottom plate 32, and the two sides of the tee joint 3 are arc-shaped. Thus, with the arc-shaped design of the tee joint 3, the inner right-angle sides of the tee joint 3 are converted into arc segments. When dragging the cable, the resistance is reduced. Compared with ordinary elbows, the tee joint 3 in this embodiment can reduce cable wear, making the dragging of the wire smoother.
