[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0032] Reference Figure 1 and Figure 5 As shown, this utility model discloses a rack-mounted optical splitter with a direct fiber output circular hole, comprising:

[0033] Box 1, the box 1 includes a bottom plate 11, a top plate 12, a baffle 13 and a pair of side plates 14, the baffle 13 is arranged perpendicular to the bottom plate 11 along the length direction of the bottom plate 11, the pair of side plates 14 are arranged at both ends of the baffle 13 and connected to the bottom plate 11, the top plate 12 is arranged on the top of the bottom plate 11, and the top plate 12 is fastened to the side of the baffle 13 and the side plates 14 away from the bottom plate 11;

[0034] The disassembly part 2 includes a first panel 21 and a second panel 22. The first panel 21 and the second panel 22 are disposed on the side of the box body 1 away from the baffle 13. The first panel 21 and the second panel 22 are disposed between two side panels 14. The first panel 21 is disposed on top of the second panel 22 and is connected to the top plate 12. The second panel 22 is connected to the bottom plate 11. At least one set of first notches 211 are provided through the side of the first panel 21 away from the top plate 12. At least one set of second notches 221 are provided through the side of the second panel 22 away from the bottom plate 11. The first panel 21 and the second panel 22 are fitted together, and the first notches 211 and the second notches 221 are spliced ​​together to form a wire hole 23.

[0035] Reference Figures 2-5 As shown, in this utility model, the box body 1 serves as a supporting structure, and the interior is used to install the beam splitter module 3. Cables need to pass through the box body 1 to connect with the beam splitter module 3 inside. In this utility model, the box body 1 has a rectangular structure. Specifically, in the actual production process, the bottom plate 11 is marked with lines, and three sides are bent to form a baffle 13 and a pair of side plates 14. The top plate 12 is set on the side away from the bottom plate 11 to form the box body 1. The side of the box body 1 opposite to the baffle 13 is an open port for installing the disassembly part 2.

[0036] Reference Figures 6-10 As shown, the entire disassembly section 2 includes a first panel 21 and a second panel 22. The first panel 21 and the second panel 22 are positioned at the open port of the aforementioned housing 1, i.e., on the side away from the baffle 13. The first panel 21 is positioned on top of the second panel 22. Three sides of the first panel 21 are connected to the top plate 12 and the two side plates 14, respectively. Three sides of the second panel 22 are connected to the bottom plate 11 and the two side plates 14, respectively. After the first panel 21 and the second panel 22 are fitted together, they seal the open portion of the aforementioned housing 1. In this invention, the first panel 21 and the second panel 22 are respectively provided with a first notch 211 and a second notch 221 on the fitted side. The positions of the first notch 211 and the second notch 221 correspond so that the first notch 211 and the second notch 221 are spliced ​​together to form a complete cable passage hole 23 for cable insertion.

[0037] In actual installation, first connect the second panel 22 to the base plate 11, then place the cable in the second notch 221, and then fasten the side of the first panel 21 with the first notch 211 onto the cable surface, placing the cable in the cable passage hole 23. Finally, connect the top plate 12 to the first panel 21. Conversely, when it is necessary to disassemble the optical splitter and remove the cable, remove the top plate 12, then remove the first panel 21 to remove the cable.

[0038] This invention employs a split panel structure, allowing for flexible removal of the built-in splitter's cables. This enables the built-in splitter components to be opened and replaced in different situations, facilitating easy installation and removal. Operators can quickly disassemble the unit, enabling rapid inspection and replacement of components within the housing 1. This not only provides flexible operation, saves time, and facilitates easy installation and removal, but also effectively improves work efficiency.

[0039] Furthermore, referring to Figure 8 and Figure 10 As shown, the first panel 21 and the second panel 22 are both hollow sheet metal parts. The side of the first notch 211 and the second notch 221 closest to the baffle 13 is a U-shaped opening, and the side of the first notch 211 and the second notch 221 away from the baffle 13 is a semi-circular opening.

[0040] Specifically, both the first panel 21 and the second panel 22 are sheet metal bending structures with hollow interiors. A first notch 211 penetrates the first panel 21, forming two coaxially arranged first notches 211 on both sides of the first panel 21. Similarly, two coaxially arranged second notches 221 are formed on both sides of the second panel 22. As a preferred embodiment of this invention, the first notch 211 and the second notch 221 on the side furthest from the interior of the housing 1 are semi-circular openings. When the first notch 211 and the second notch 221 are fitted together, they form a circular cable passage hole 23, accommodating the passage of circular cables. The first notch 211 and the second notch 221 closer to the inside are U-shaped openings. The distance between the two sides of the U-shaped notch is small, which can fix the cable. Furthermore, the hollow structure of the first panel 21 and the second panel 22 can cooperate with the heat-shrink fasteners on the cable. The heat-shrink fasteners on the surface of the cable fix the cable in the hollow slot, preventing the optical cable from being pulled out and subjected to force.

[0041] Furthermore, referring to Figure 2 As shown, a latch 212 is provided on the side of the first panel 21 that is in contact with the top plate 12, and a latch 15 that engages with the latch 212 is provided on the surface of the top plate 12. Specifically, the first panel 21 and the top plate 12 are engaged by the latch 15, which facilitates the quick disassembly of the entire box 1.

[0042] Furthermore, referring to Figure 4As shown, the surface of the top plate 12 has an installation opening 121, and the latch 15 is detachably connected to the installation opening 121.

[0043] Specifically, the mounting port 121 is provided through the top plate 12. During the assembly process, the latch 15 is installed in the mounting port 121 so that the latch 15 can cooperate with the snap-fit ​​212 on the first panel 21.

[0044] Furthermore, referring to Figure 6 As shown, the first panel 21 and the second panel 22 are detachably connected to the side panel 14.

[0045] Specifically, the first panel 21 and the second panel 22 are connected to the side plate 14 on both sides by self-tapping screws. At the same time, the second panel 22 is also connected to the base plate 11 by self-tapping screws.

[0046] Furthermore, referring to Figure 3 As shown, the side plate 14 has a first folded edge 141 on the side near the top plate 12, and the top plate 12 is fitted with the first folded edge 141. The baffle 13 has a second folded edge 131 on the side near the top plate 12, and the surface of the top plate 12 has a flange 122 that cooperates with the second folded edge 131.

[0047] Specifically, both the first folded edge 141 and the second folded edge 131 fold inwards towards the inside of the box 1. The first folded edge 141 supports the top plate 12, preventing it from falling into the box 1, while the second folded edge 131 secures the top plate 12. In the actual assembly process, the folded edge 122 of the top plate 12 is first engaged with the second folded edge 131 to limit one side of the folded edge 122. Then, the top plate 12 is brought into contact with the first folded edge 141 to provide support for both sides of the top plate 12. Finally, the latch 15 on the top plate 12 is engaged with the first panel 21 to complete the installation and fixation of the entire top plate 12.

[0048] Furthermore, it also includes a beam splitting module 3, which is disposed inside the housing 1 and connected to the base plate 11. A fixing ring 111 is provided on the surface of the base plate 11 along the circumference of the beam splitting module 3.

[0049] The beam splitter module 3 is installed on the base plate 11 inside the housing 1. The surface of the base plate 11 is provided with multiple fixing rings 111, which can be set on three sides of the beam splitter module 3. The fixing rings 111 on opposite sides can be fixed to the beam splitter module 3 with Velcro. The fixing ring 111 on the other side is set close to the side plate 14 to prevent the side plate 14 from being directly impacted by external force deformation.

[0050] Furthermore, an ear seat 16 is provided on the side of the side plate 14 away from the first panel 21 and the second panel 22.

[0051] Specifically, the entire box 1 can be installed with different cabinets through the ear seats 16 on the side panel 14, which facilitates installation and fixation with the slide rails inside the cabinet.

[0052] In summary, this utility model introduces a rack-mounted optical splitter with a direct-output fiber optic circular hole. During actual installation, firstly, the second panel 22 is connected to the base plate 11. Then, the cable is placed inside the second notch 221. Next, the side of the first panel 21 with the first notch 211 is fastened to the cable surface, placing the cable inside the cable passage hole 23. Finally, the top plate 12 is connected to the first panel 21. Conversely, when it is necessary to disassemble the optical splitter to remove the cable, the top plate 12 is removed, and then the first panel 21 is taken off to remove the cable. This utility model adopts a split panel structure, allowing for flexible removal of the cable from the built-in splitter. This enables the built-in splitter components to be opened and replaced in different situations, facilitating easy installation and removal. Operators can quickly disassemble the unit, facilitating rapid inspection and replacement of components inside the housing 1. This not only provides flexible operation, saves time, and facilitates easy installation and removal, but also effectively improves work efficiency.
