[0003] After retrieval, the "optical fiber distribution box" disclosed in Chinese Patent Publication No. CN209198726U includes a distribution box body. A wiring groove is formed on the distribution box body. A plurality of cover plates are formed on the distribution box body through tear points or tear lines. When the cover plates are disassembled from the distribution box body, wiring grooves are formed. The wire harness enters the distribution box body from the wiring grooves and is led out from the distribution box body through the wiring groove. The cover plates formed on the distribution box body have different shapes, and different-shaped cover plates form different-shaped wiring grooves when disassembled on the distribution box body.

[0004] This patent realizes the wiring work by arranging a wiring groove at one end of the distribution box body. However, since the gap between the distribution box and the inner wall of the equipment rack is small after the distribution box is installed on the distribution frame, the operating space is limited, making it inconvenient to operate when inserting optical fiber connectors. Moreover, the optical fiber at the optical fiber connector is easily bent significantly after wiring, which causes the cable at the optical fiber connector to be easily broken, thus affecting the service life of the optical fiber connector. In view of this, the utility model proposes an MPO-LC conversion box for an MODF distribution frame. Summary of the Utility Model

[0005] The utility model proposes an MPO-LC conversion box for an MODF distribution frame, which solves the problem of inconvenient wiring operation at the end of the existing distribution box.

[0007] Preferably, two slots corresponding to the MPO adapters are opened at the bottom of the conversion box body, and the two MPO adapters are slidably matched with the corresponding slots.

[0008] Preferably, the number of the LC adapters is 24, and the LC adapters are divided into two groups of 12 each and are respectively electrically connected with the two MPO adapters through optical fibers.

[0009] Preferably, the conversion box body further includes a wire reel for winding the optical fibers, and the wire reel is fixedly connected inside the housing.

[0010] Preferably, elastic clamping strips are fixedly connected to both ends of the housing, and the two elastic clamping strips are slidably connected with the inner wall of the card slot of the distribution frame.

[0011] Preferably, the area of the panel is larger than the opening area of the card slot of the distribution frame, and one side of the panel abuts against the outer wall of the distribution frame.

[0012] The working principle and beneficial effects of the present utility model are as follows:

[0013] 1. By arranging the two MPO adapters at the bottom of the housing, it is convenient for the optical fiber connectors to be directly inserted into the MPO adapters from below the distribution frame. There is a large operating space below the conversion box body, which is convenient for personnel to carry out wiring work. Moreover, the optical fibers will not be bent significantly after the optical fiber connectors are inserted into the MPO adapters, thus avoiding the problem that the cables at the optical fiber connectors are broken due to bending, and further greatly extending the service life of the optical fiber connectors;

[0014] 2. The surplus optical fibers on all LC adapters can be wound through the wire reel, which can avoid the problem that the surplus optical fibers are entangled with each other inside the housing, causing difficulties in subsequent arrangement. The elastic clamping strips can achieve the quick matching of the housing and the slot of the distribution frame. The elasticity of the elastic clamping strips can exert pressure on the inner wall of the slot of the distribution frame, so that the housing and the slot of the distribution frame are kept stable. When disassembling the conversion box body, by pressing the two elastic clamping strips to disengage them from the inner wall of the slot of the distribution frame, the housing can be directly taken out, thus realizing the quick installation and disassembly of the housing, and the operation is very convenient.
