[0047] Furthermore, if Figure 6 As shown, in this embodiment, the wiring unit box 200 includes a chassis 220, a plurality of fiber splicing trays 230, and an adapter panel 240. The chassis 220 is movably placed on the first shelf 210, and a plurality of fiber splicing trays 230 are stacked and fixed on the upper surface of the chassis 220. The adapter panel 240 is vertically arranged on the front side of the chassis 220, and the lower edge of the adapter panel 240 is connected to the front edge of the chassis 220. Specifically, the wiring unit box 200 is a 19-inch rotary 120-core ODF unit box, and five 24-core fiber splicing trays 230 are installed on the chassis 220. These fiber splicing trays 230 are stacked to facilitate fiber splicing, and the adapter panel 240 is a 120-core SC adapter panel 240. Here, one end of the adapter panel 240 along the left-right direction is hinged to the first side panel 212 of the corresponding side through the first hinge 250, and the other end is detachably screwed to the other first side panel 212 through the hand screw 260, i.e., a screw that cannot be loosened. In this way, when the wiring unit box 200 needs to be pulled out, the hand screw 260 can be conveniently unscrewed by hand without tools, and then the chassis 220 is rotated toward the side with the first hinge 250 to realize the side pull and opening of the wiring unit box 200.

[0049] Furthermore, the splitter rack 300 further includes a Latin buckle 340, and the front end of the plugboard is connected to the rack shell 320 through the Latin buckle 340. It can be understood that this card-type Latin buckle 340 installation method has the advantages of easy deployment, plug-and-play, and convenient maintenance.

[0050] It should be noted that in this embodiment, considering that the main frame 100 of the optical fiber distribution frame is the main load-bearing body, the main frame 100 is preferably made of relatively strong and sturdy high-quality cold-rolled plate, and the splitter rack 300, plug board, and wiring unit box 200 are preferably made of high-quality aluminum alloy. Although the cost of aluminum alloy is higher than that of cold-rolled plate, and the processing technology is also more difficult than cold-rolled plate, high-quality aluminum alloy has the advantages of beautiful appearance and light weight, which is more conducive to subsequent maintenance operations and transportation cost reduction. Of course, in other embodiments, the splitter rack 300, plug board, and wiring unit box 200 can also be made of materials such as but not limited to cold-rolled plate, and customers can choose according to actual needs.
