[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-4 , an anti-interference ceiling wiring harness assembly, including a top connecting plate 1, a lower cover box 6, and an upper cover box 5. The lower cover box 6 and the upper cover box 5 are made of aluminum alloy, which has a good electromagnetic shielding effect and can resist interference with the wiring harness inside the lower cover box 6 and the upper cover box 5. The top connecting plate 1 is provided with mounting holes 2 at the four corners. The lower cover box 6 is fixedly provided on the top of the top connecting plate 1. The edge positions of the four corners of the lower cover box 6 and the upper cover box 5 are fixedly provided with edge rings 61. The edge rings 61 provided on the edges of the lower cover box 6 and the upper cover box 5 have a common thread with a fixing screw 52 screwed in. Upper connecting rings 13 are fixedly provided on both sides of the upper cover box 5. Lower connecting rings 10 are fixedly provided on both sides of the upper cover box 5 at any time. The upper connecting ring 13 has the same diameter as the lower connecting ring 10 and is used to wrap the wires of the entire ceiling wiring harness.

[0022] The inner cavity of the lower cover box 6 is movably placed with a ceiling wire harness body 9, and the top of the upper cover box 5 is provided with an anti-loosening component to prevent the plug of the ceiling wire harness from loosening. Positioning columns 51 are fixedly provided at the four corners of the bottom of the upper cover box 5, and auxiliary holes 62 are fixedly provided at the four corners of the top of the lower cover box 6. The diameter of the positioning column 51 is equal to the diameter of the auxiliary hole 62. The auxiliary hole 62 and the positioning column 51 are used for quick positioning and installation between the upper cover box 5 and the lower cover box 6.

[0023] The anti-loosening assembly includes an anti-loosening fork 7, an adjusting screw 8, and an extension block 71. A transverse groove 11 is provided on the top of the upper cover box 5.
