Abstract

This utility model proposes a pull-out fiber optic distribution frame, relating to the field of fiber optic distribution frame technology. It includes a frame housing with a mounting box slidably connected inside via a slide rail. Multiple adapters are mounted on the mounting box, and each adapter has two rows of fiber optic connectors. A vertical plate is fixedly connected to one side of the mounting box, opposite the adapters. One side of the vertical plate has multiple square through slots. This utility model uses a cable bundle assembly to connect the fiber optic cables to the fiber optic connectors of the adapters. After connection, the cable bundle assembly clamps and fixes the fiber optic cables, keeping the area between the cable bundle assembly and the adapter in a natural state.

Description

Technical Field

[0001] This utility model belongs to the field of fiber optic distribution frame technology, and in particular relates to a pull-out fiber optic distribution frame. Background Technology

[0002] A pull-out fiber optic patch panel is a type of fiber optic cabling equipment with a pull-out function. It is typically installed in a cabinet or rack for the connection, distribution, and management of optical fibers. Its main feature is that the patch panel can be pulled out of the cabinet like a drawer, facilitating fiber optic connection, testing, and maintenance by technicians. Inside the patch panel are fiber optic adapters (such as LC, SC, FC interfaces) for connecting fiber optic patch cords and trunk fibers. When a fiber optic connection is needed, one end of the patch cord is inserted into the adapter, and the other end is connected to the equipment or another fiber. The patch panel is connected to the cabinet via a rail and pulley system. Technicians can hold the handle of the patch panel and smoothly pull it out of the cabinet. During the pulling process, the fiber optic adapters and the internal fiber optic connection structure remain relatively stable, ensuring the reliability of the fiber optic connection.

[0003] During the process of pulling out the patch panel, the optical fiber may be subjected to a certain degree of stretching, bending or twisting, which will cause stress at the connection point between the optical fiber and the optical fiber adapter (such as LC, SC, FC interface) installed in the patch panel, resulting in micro-damage to the optical fiber (such as micro-crack propagation), affecting the connection performance and optical signal transmission quality of the optical fiber, accelerating the aging of the optical fiber, and shortening the service life of the optical fiber. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes a pull-out fiber optic patch panel, which more precisely solves the problems described above.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model proposes a pull-out fiber optic distribution frame, including a frame housing. A mounting box is slidably connected inside the frame housing via a slide rail. Multiple adapters are mounted on the mounting box, and each adapter has two rows of fiber optic connectors. A vertical plate is fixedly connected to one side of the mounting box, opposite to the adapters. Multiple square through slots are provided on one side of the vertical plate, each square through slot corresponding to an adapter. A horizontal plate is fixedly connected to the inner wall of each square through slot, and a cable bundle assembly is mounted on the horizontal plate.

[0007] Preferably, the cable assembly includes a fixing base, which is fixedly connected to a horizontal plate. The fixing base has two square through slots, which are respectively opposite to two rows of fiber optic connectors on the adapter. Support plates are fixedly connected to both sides of the fixing base, which are located below the two square through slots. Elastic blocks are fixedly connected to the upper surfaces of the two support plates, and elastic compression blocks are provided above the elastic blocks.

[0008] Preferably, two guide rods are fixedly connected to the upper surface of the fixed base, a sliding plate is slidably connected to the guide rods, pressure plates are fixedly connected to both sides of the sliding plate, and mounting plates are fixedly connected to the lower surface of the pressure plates. Two elastic compression blocks are fixedly connected to the two mounting plates respectively. A screw is rotatably connected to the upper surface of the fixed base, and the screw passes through the sliding plate upward and is threadedly connected to the sliding plate.

[0009] Preferably, the elastic compression block and the side opposite to the elastic block are provided with opposing arc-shaped grooves.

[0010] Preferably, the upper surface of the frame shell is rotatably connected to a cover plate, and the cover plate is provided with a through mounting groove, in which a first dustproof net is installed.

[0011] Preferably, both sides of the mounting box are provided with heat dissipation grooves, and a second dustproof net is installed in the heat dissipation grooves.

[0012] Preferably, bent pipes are fixedly connected to the square through grooves on the upright plate, and the bent pipes are located on the outside of the upright plate.

[0013] The pull-out fiber optic distribution frame proposed in this utility model can bring the following beneficial effects:

[0014] 1. By setting up the cable bundle assembly, the optical fiber passes through the square through slot at the corresponding height on the fixing base, and then connects to the adapter. After connection, the position of the optical fiber is adjusted so that the optical fiber is located in the corresponding arc-shaped slot. Then, the screw is rotated to control the sliding plate to descend, which in turn lowers the mounting plate. The elastic compression block is pressed against the elastic block to compress and fix the optical fiber in the middle. When the mounting box is pulled out, although it will cause pulling on the area outside the cable bundle assembly, it will not affect the area between the cable bundle assembly and the adapter. It will not cause stretching, bending or twisting in this area, avoiding wear and damage to the optical fiber and adapter connector, which will affect the service life and connection status.

[0015] 2. By setting a cover plate, which is located above the optical fiber and adapter, after the optical fiber is installed, the cover plate is flipped over to cover the adapter and optical fiber in the installation box for protection and dust prevention. However, by setting a first dustproof net and a second dustproof net, the impact of the cover plate on heat dissipation is reduced. Attached Figure Description

Detailed Implementation

[0023] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0024] like Figures 1-4 As shown, an embodiment of this utility model proposes a pull-out fiber optic distribution frame, including a frame housing 1. A mounting box 2 is slidably connected to the frame housing 1 via a slide rail. Multiple adapters 3 are mounted on the mounting box 2, and each adapter 3 has two rows of fiber optic connectors. A vertical plate 4 is fixedly connected to one side of the mounting box 2, opposite to the adapters 3. One side of the vertical plate 4 has multiple square through slots, each corresponding to one of the adapters 3. Horizontal plates 5 are fixedly connected to the inner walls of each square through slot, and cable bundle assemblies 6 are mounted on the horizontal plates 5. When the mounting box 2 slides into the frame housing 1, the adapter 3 connectors are exposed on the outside, facilitating fiber optic connection. There is a certain distance between board 4 and adapter 3. When connecting optical fiber to adapter 3, the optical fiber first passes through the square through slot into the upright board 4, and then connects to the optical fiber connector of adapter 3. After connection, the optical fiber is clamped and fixed by the cable bundle assembly 6, so that the area between the cable bundle assembly 6 and adapter 3 in the optical fiber is in a natural state. In this way, when the installation box 2 is pulled out, although the area outside the cable bundle assembly 6 will be pulled, it will not affect the area between the cable bundle assembly 6 and adapter 3, and will not cause stretching, bending or twisting to this area, thus avoiding wear and damage to the connector of the optical fiber and adapter 3, which will affect the service life and connection status.

[0025] like Figure 2 , Figure 3 and Figure 4As shown, the cable bundle assembly 6 includes a fixing base 61, which is fixedly connected to the horizontal plate 5. The fixing base 61 has two square through slots, which are respectively opposite to two rows of fiber optic connectors on the adapter 3. Support plates 62 are fixedly connected to both sides of the fixing base 61, located below the two square through slots. Elastic blocks 63 are fixedly connected to the upper surfaces of both support plates 62, and elastic compression blocks 64 are provided above each elastic block 63. Two guide rods 7 are fixedly connected to the upper surface of the fixing base 61, and sliding plates 8 are slidably connected to the guide rods 7. Pressure plates 9 are fixedly connected to both sides of the sliding plates 8, and mounting plates 10 are fixedly connected to the lower surfaces of the pressure plates 9. The two elastic compression blocks 64 are respectively fixedly connected to the two mounting plates 10. The upper surface of the fixed seat 61 is rotatably connected to the screw 11, which passes through the sliding plate 8 and is threadedly connected to the sliding plate 8. The elastic compression block 64 and the elastic block 63 are provided with corresponding arc-shaped slots on opposite sides. When the optical fiber passes through the vertical plate 4, it first passes through the square through slot at the corresponding height on the fixed seat 61, and then connects to the adapter 3. After connection, the position of the optical fiber is adjusted so that it is located in the corresponding arc-shaped slot. Then, the screw 11 is rotated to control the sliding plate 8 to descend, thereby causing the mounting plate 10 to descend. The elastic compression block 64 presses against the elastic block 63 to compress and fix the optical fiber in the middle. After fixing, the optical fiber is adjusted so that the optical fiber between the fixed seat 61 and the adapter 3 is in a natural state. The operation is simple.

[0026] like Figure 1 and Figure 2 As shown, the upper surface of the frame shell 1 is rotatably connected to a cover plate 12. The cover plate 12 has a through mounting groove, in which a first dustproof net 13 is installed. Both sides of the mounting box 2 are provided with heat dissipation grooves, in which a second dustproof net 14 is installed. The cover plate 12 is located above the optical fiber and the adapter 3. After the optical fiber is installed, the cover plate 12 is flipped over to cover the adapter 3 and the optical fiber in the mounting box 2 for protection and dust prevention. However, by setting the first dustproof net 13 and the second dustproof net 14, the impact of the cover plate 12 on heat dissipation is reduced.

[0027] like Figure 1 and Figure 2 As shown, bent pipes 15 are fixedly connected in the square through slots on the upright plate 4. The bent pipes 15 are located on the outside of the upright plate 4, and the opening on the other side of the bent pipes 15 faces downward. When installing optical fibers, the optical fibers pass through the bent pipes 15 and enter the installation box 2. The bent pipes 15 can protect the optical fibers. At the same time, the bent pipes 15 face downward, which can block floating dust to a certain extent and prevent a large amount of floating dust from entering the installation box 2 through the square through slots.

[0028] Working principle: When installing the optical fiber, the optical fiber passes through the bend tube 15 into the installation box 2. First, the optical fiber passes through the square through slot at the corresponding height on the fixing seat 61, and then connects with the adapter 3. After connection, the position of the optical fiber is adjusted so that the optical fiber is located in the corresponding arc-shaped slot. Then, the screw 11 is rotated to control the sliding plate 8 to descend, which in turn causes the installation plate 10 to descend. The elastic compression block 64 presses against the elastic block 63 to compress and fix the optical fiber in the middle. After fixing, the optical fiber is adjusted so that the optical fiber between the fixing seat 61 and the adapter 3 is in a natural state. Then, the cover plate 12 is flipped over to cover the adapter 3 and the optical fiber in the installation box 2.
