Description

Technical Field

[0002] Fiber optic distribution frames are core components of optical communication systems, primarily used for the integrated management of optical paths between optical cables and communication equipment, or between devices. Their modular design enables flexible connection, path allocation, and signal distribution of fiber optic links, and they can typically be deployed in standard cabinets or on walls. By adding adapter components, they can also meet the access requirements of different types of optical fibers.

[0003] Chinese Patent No. CN220894614U discloses a pull-out fiber optic distribution integration device, including a patch panel housing and a patch panel pull-out tray. The patch panel pull-out tray is slidably connected to the patch panel housing. The patch panel pull-out tray includes an optical cable fixing seat, a fiber fusion splice tray, fiber coiling wheels, and a flange fixing frame, all mounted on the bottom plate of the pull-out tray. The optical cable fixing seat is fixed to the bottom plate of the pull-out tray by a pad. Two fiber coiling wheels are symmetrically arranged on both sides of the fiber fusion splice tray. The flange fixing frame is provided with several fiber optic flanges, which are used for connecting pigtails and fiber optic patch cords.

[0020] Example 1

[0021] like Figures 1-4 As shown in the figure, the fiber optic patch panel proposed in this embodiment includes a patch panel pull-out plate 1 and a cable fixing mechanism; the patch panel pull-out plate 1 is provided with two inlet holes 2 and outlet holes 3.

[0022] The cable fixing mechanism includes two bases 4 mounted on the cable tray pull plate 1, two first upright plates 5 mounted on the bases 4, a rotating frame 6 rotatably connected to the first upright plates 5, two first springs 7 symmetrically distributed on the rotating frame 6, a first clamping frame 8 mounted on the first springs 7, a support rod 10 vertically distributed on the bases 4, a second clamping frame 11 mounted on the support rod 10, two second upright plates 13 mounted on the bases 4, and a fixing component mounted on the second upright plates 13; both the first clamping frame 8 and the second clamping frame 11 are provided with elastic anti-slip pads 9, and the first clamping frame 8 is provided with two symmetrically distributed guide rods 12, which are slidably connected to the rotating frame 6, and the first springs 7 are sleeved on the guide rods 12.

[0023] The fixing assembly includes two connecting rods 14 mounted on the second upright plate 13, a fixing plate 15 rotatably connected to the connecting rods 14, an insert rod 16 slidably connected to the fixing plate 15, a protruding ring 17 coaxially mounted on the insert rod 16, and a second spring 18 with its two ends mounted on the fixing plate 15 and the protruding ring 17 respectively; the rotating frame 6 is provided with a positioning hole 20 for inserting the insert rod 16, and a ball grip 19 is provided at the end of the insert rod 16 away from the protruding ring 17.

[0024] In this embodiment, after the cable enters the inside of the patch panel pull-out tray 1 through the inlet hole 2, it passes through and is placed on the second clamping frame 11. Then, rotating the rotating frame 6 causes the first clamping frame 8 to rotate. When the first clamping frame 8 contacts the cable, as the rotating frame 6 continues to rotate, the squeezing force between the first clamping frame 8 and the cable will continuously compress the first spring 7, so as to achieve the function of fixing cables of different sizes. When the rotating frame 6 rotates to the fixed position, the insert rod 16 is pulled by the ball 19, so that the convex ring 17 and the fixing plate 15 compress the second spring 18. Then, the insert rod 16 is aligned with the positioning hole 20 on the rotating frame 6 and the ball 19 is released. Under the action of the second spring 18, the insert rod 16 will be inserted into the interior of the positioning hole 20, thus completing the fixing operation of the rotating frame 6. This avoids the need to use tools to operate the threaded fasteners, reduces the difficulty of fixing the cable, improves the ease of use of the patch panel, and has good practicality.

[0025] Example 2

[0026] like Figure 1 and Figure 4 As shown in the figure, the fiber optic patch panel proposed in this embodiment, compared with the first embodiment, has a fiber fusion splice tray 21 and two symmetrically distributed fiber optic rollers 22 on the patch panel pull-out tray 1, a flange fixing bracket 23 on the patch panel pull-out tray 1, and twelve linearly arrayed fiber optic flanges 24 on the flange fixing bracket 23.

[0027] A housing 25 is slidably connected to the patch panel pull-out tray 1. Two first connecting ears 26 and two second connecting ears 27 are respectively provided on the patch panel pull-out tray 1 and the housing 25.

[0028] In this embodiment, the optical cable and pigtail are spliced ​​together via the fusion splice tray 21, and the fiber spool 22 provides the fiber cable with an optimized arc path that meets transmission requirements. The pigtail end is cascaded with the fiber optic patch cord via the fiber optic flange 24 on the flange mounting bracket 23. Finally, the patch cord extends to the outside of the patch panel pull-out tray 1 through the outlet hole 3, forming a standardized equipment interconnection link channel. The first connecting ear 26 and the second connecting ear 27 are used to close and fix the patch panel pull-out tray 1 to the housing 25.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
