[0024] Combined with Figures 1 to 3As shown in the figure, the present utility model provides an optical fiber splitting box, which includes a box cover 1, a box body 2, a cover plate 3 and a plug-in optical splitter 4. The inside of the box body 2 is hollow and one end is set as an open end. The cover plate 3 is arranged at the open end and is connected to the box body 2 by threaded fasteners. An installation cavity is formed between the cover plate 3 and the bottom plate 21 of the box body 2, and the plug-in optical splitter 4 is installed in the installation cavity. A cable inlet / outlet hole is provided on one side wall of the box body 2, and the cable inlet / outlet hole is opposite to the interface of the plug-in optical splitter 4. A notch is provided on the part of the cover plate 3 close to the cable inlet / outlet hole, and the notch is located between the cable inlet / outlet hole and the interface of the plug-in optical splitter 4. The box cover 1 is arranged at the open end and is movably connected to the box body 2.

[0025] Specifically, the box body 2 is in a cuboid structure, hollow inside, and the open end is arranged at the upper end of the box body 2, and a cable inlet / outlet hole is provided on the side wall of the box body 2 facing the negative direction of the Y axis. The cover plate 3 can be a sheet metal part or a plastic part. The cover plate 3 is located at the open end of the box body 2 and is spaced apart from the bottom plate 21 of the box body 2. The edge of the cover plate 3 can be connected to the box body 2 by threaded fasteners. After the cover plate 3 is connected, an installation cavity is formed between the cover plate 3 and the bottom plate 21. The plug-in optical splitter 4 is located in this installation cavity and can be installed on the bottom plate 21 by threaded fasteners. The cable inlet / outlet holes on the box body 2 can include 3 ordinary cable inlet / outlet holes and a drop cable inlet / outlet hole 20. Among them, when the plug-in optical splitter 4 is a 1:8 plug-in optical splitter, the number of drop cable inlet / outlet holes 20 is 8. A notch is provided on the part of the cover plate 3 close to the cable inlet / outlet hole, that is, the part of the cover plate 3 close to the side wall of the box body 2 facing the negative direction of the Y axis. The notch communicates with the inside of the box body 2 and is located between the cable inlet / outlet hole and the interface of the plug-in optical splitter 4. When wiring, the ordinary optical cable 8 enters the box body 2 through 3 ordinary cable inlet / outlet holes and is connected to the interface on the plug-in optical splitter 4. The plug-in optical splitter 4 is installed on the bottom plate 21 of the box body 2 by threaded fasteners. The cover plate 3 covers the plug-in optical splitter 4 and is installed at the open end of the box body 2 by threaded fasteners, and the notch on the cover plate 3 enables the wiring personnel to intuitively see the drop cable optical fiber interface of the plug-in optical splitter 4, so that the drop cable enters the box body 2 from the drop cable inlet / outlet hole 20 and is connected to the drop cable optical fiber interface of the plug-in optical splitter 4. During the wiring process of the drop cable, the whole plug-in optical splitter 4 is always covered by the cover plate 3, and only the drop cable optical fiber interface of the plug-in optical splitter 4 is exposed. After the drop cable is wired, the box cover 1 is covered on the open end of the box body 2, and the box cover 1 covers the drop cable optical fiber interface of the plug-in optical splitter 4. And during the subsequent wiring process of the user, even if the box cover 1 is opened, the cover plate 3 can still prevent the plug-in optical splitter 4 from being exposed outside, thus avoiding damage to the plug-in optical splitter 4 caused by external factors. Among them, a sealing ring can be arranged in the drop cable inlet / outlet hole 20 to achieve the purpose of dust prevention.

[0026] Therefore, in this embodiment, the ordinary optical cable enters the inside of the box body 2 through the optical cable inlet and outlet hole, and after being connected to the plug-in optical splitter 4 inside the box body 2, the cover plate 3 located at the opening end of the box body 2 and connected to the box body 2 by threaded fasteners can cover the plug-in optical splitter 4, so that the plug-in optical splitter 4 is installed in the installation cavity formed between the cover plate 3 and the bottom plate 21 of the box body 2, thereby forming a protective housing outside the plug-in optical splitter 4, and making the optical cable inlet and outlet hole opposite to the interface of the plug-in optical splitter 4. A notch is provided in the part of the cover plate 3 close to the optical cable inlet and outlet hole, and the notch is located between the optical cable inlet and outlet hole and the interface of the plug-in optical splitter 4. The notch facilitates the subsequent wiring of the user optical cable fiber. After the user optical cable fiber is wired, the box cover 1 arranged at the opening end and movably connected to the box body 2 can cover the box body 2 and the notch, thereby realizing double protection for the plug-in optical splitter 4 and effectively avoiding damage to the plug-in optical splitter 4.

[0027] Optionally, as shown in Figures 1 to 3 , the box cover 1 is rotatably connected to the box body 2, and / or, the box cover 1 is connected to the box body 2 through a lock catch 11 and a lock catch spring 12.

In this way, by the box cover 1 being rotatably connected to the box body 2, and / or, the box cover 1 being connected to the box body 2 through a lock catch 11 and a lock catch spring 12, not only is the connection method between the box cover 1 and the box body 2 enriched, but also the stability of the box cover 1 buckled on the box body 2 can be ensured.

[0028] Optionally, as shown in Figures 1 to 3 , the box cover 1 is also connected to the box body 2 through an anti-theft lock 5. Specifically, the anti-theft lock 5 and the aforementioned lock catch 11 and lock catch spring 12 are located on the same side. After the box body 1 is buckled on the box body 2, the anti-theft lock 5 can ensure the tightness of the box body 1 buckled on the box body 2.

[0029] In this way, the box cover 1 is also connected to the box body 2 through the anti-theft lock 5. The anti-theft lock 5 can not only achieve the purpose of anti-theft, but also further improve the locking ability of the lock catch, so as to further improve the stability of the box cover 1 buckled on the box body 2.

[0030] Optionally, as shown in Figures 1 to 3 , a dust cover 51 is provided on the anti-theft lock 5. Specifically, the dust cover 51 can be a rubber cover and covers the anti-theft lock 5.

[0031] In this way, by providing the dust cover 51 on the anti-theft lock 5, the dust cover 51 can seal the anti-theft lock 5, thereby preventing dust or rainwater from entering the anti-theft lock 5 and prolonging the service life of the anti-theft lock 5.

[0032] Optionally, in combination with Figures 1 to 3 As shown, one end of the box cover 1 facing the box body 2 is provided with a sealing strip, and one end of the box body 2 facing the box cover 1 is provided with a rib 22. The sealing strip and the rib 22 both extend along the edge of the box body 2, and the rib 22 is used to squeeze the sealing strip.

[0033] Specifically, the end of the box cover 1 facing the box body 2 refers to the end face where the box cover 1 is in contact with the box body 2 when the box cover 1 is buckled on the box body 2. The box cover 1 is provided with a groove on this end face, and the groove extends along the edge of the box opening of the box body 2. A sealing strip is arranged in the groove. Correspondingly, a rib 22 is arranged on the edge of the box opening of the box body 2. When the box cover 1 is buckled on the box body 2, the rib 22 can squeeze the sealing strip.

[0034] In this way, by providing a sealing strip at one end of the box cover 1 facing the box body 2, a rib 22 at one end of the box body 2 facing the box cover 1, with the sealing strip and the rib 22 both extending along the edge of the box body 2 and the rib 22 squeezing the sealing strip, the sealing effect between the box cover 1 and the box body 2 can be realized by the squeezing of the rib 22 on the sealing strip, so as to improve the sealing effect between the box cover 1 and the box body 2.

[0035] Optionally, in combination with Figure 3 As shown, the optical fiber splitting box further includes an optical splitter partition plate, which is arranged between the cover plate 3 and the bottom plate 21. Two plug-in optical splitters 4 are respectively installed between the optical splitter partition plate and the cover plate 3 and between the optical splitter partition plate and the bottom plate 21, and both of the two plug-in optical splitters 4 are connected to the bottom plate 21 through threaded fasteners.

[0036] Specifically, the optical splitter partition plate is a sheet metal part or a plastic part. The optical splitter partition plate can be installed between the cover plate 3 and the bottom plate 21 by screws, so that a double-layer installation cavity is formed between the cover plate 3 and the bottom plate 21. The first installation cavity is between the cover plate 3 and the optical splitter partition plate, and the second installation cavity is between the optical splitter partition plate and the bottom plate 21. The two plug-in optical splitters 4 are respectively installed in the first installation cavity and the second installation cavity. Then, the two plug-in optical splitters 4 are threadedly connected to the bottom plate 21 through the same screw. In this way, by arranging the optical splitter partition plate between the cover plate 3 and the bottom plate 21, installing the two plug-in optical splitters 4 between the optical splitter partition plate and the cover plate 3 and between the optical splitter partition plate and the bottom plate 21 respectively, and connecting both of the two plug-in optical splitters 4 to the bottom plate 21 through screws, the utilization of the internal space of the box body 2 is maximized, so as to facilitate the installation of multiple plug-in optical splitters 4 in the box body 2 to increase the number of interfaces of the optical fiber splitting box.

[0037] Combined with the above embodiments, when there are two plug-in optical splitters 4, the 16 interfaces of the two plug-in optical splitters 4 all face the side wall of the box body 2 in the negative direction of the Y-axis, and two rows of access holes 20 for drop cables are provided on this side wall. Each access hole 20 for drop cables corresponds to only one interface of the plug-in optical splitter 4, and common optical cable inlets and outlets 10 can be provided on the left and right sides of the two rows of access holes 20 for drop cables. Further, on the basis of the above embodiments, combined with Figure 2 and Figure 3 as shown, the optical fiber distribution box further includes a pressing strip 30.

During the tightening process of the screws, the pressing strip 30 can press against the plug-in optical splitter 4, so as to ensure the stability of the interface of the plug-in optical splitter 4 and avoid the offset of the interface of the plug-in optical splitter 4 during the optical cable wiring process.

[0038] Optionally, combined with Figure 3 as shown, the optical fiber distribution box further includes an optical cable fixing pressing plate 6. The optical cable fixing pressing plate 6 is connected to the bottom plate 21 through threaded fasteners and is used to clamp the common optical cable with the bottom plate 21.

[0039] Specifically, the optical cable fixing pressing plate 6 is installed on the bottom plate 21 by screws and gradually approaches the bottom plate 21 by tightening the screws to clamp the common optical cable 8 with the bottom plate 21.

[0040] In this way, by connecting the optical cable fixing pressing plate 6 to the bottom plate 21 through threaded fasteners and using it to clamp the common optical cable 8 with the bottom plate 21, the stability of the common optical cable 8 in the box body 2 can be realized.

[0041] Optionally, combined with Figure 3 as shown, the optical fiber distribution box further includes an optical fiber splicing tray 7.

[0042] Specifically, the hot melt tube is a sleeve for protecting the optical fiber splicing joint. The hot melt tube can support and protect the optical fiber joint after being heated. The optical fiber splicing tray 7 is installed on the bottom plate 21 through threaded fasteners. The optical fiber splicing tray 7 is provided with a hot melt tube clamping seat 73. The hot melt tube clamping seat 73 is provided with a card slot or a limiting structure, and the hot melt tube is installed in the card slot or the limiting structure on the hot melt tube clamping seat 73 to realize the fixation of the hot melt tube.

[0043] In this way, by installing the optical fiber splicing tray 7 on the bottom plate 21, the optical fiber splicing tray 7 is provided with a hot melt tube clamping seat 73, and the hot melt tube clamping seat 73 is used for clamping with the hot melt tube, the hot melt tube clamping seat 73 realizes the positioning of the hot melt tube to ensure the stability of the hot melt tube inside the box body 2. At the same time, the optical fiber splicing tray 7 can also be protected after the cover plate 3 is connected to the box body 2.

[0044] In the above embodiments, in combination with Figure 1 and Figure 4 as shown, the optical fiber distribution box includes a pressing block 9.
