[0002] In communication networks, optical fiber cables are important media for information transmission, and their stability and reliability are directly related to communication quality and efficiency.

[0003] Traditional optical fiber fixing and assembly methods, such as using tools such as binding tape and clamps for fixing, are not only cumbersome and inefficient, but also have unstable fixing effects. Cables can easily become loose or fall off due to external factors, thereby affecting the stability and continuity of communication transmission. To address the above problems, some improved optical fiber fixing and assembly devices have appeared on the market, such as distribution frames with automatic adsorption functions. However, these devices are often complex in structure and inconvenient to operate, making it difficult to meet the requirements of modern communication networks for efficient, stable, and secure fixing of optical fiber cables.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-Figure 3 The utility model provides a technical solution: a fiber optic distribution frame, including a shell 1, a wiring frame 2 and a communication device 3 fixedly installed on the wiring frame 2, the wiring frame 2 is fixedly installed on the inner wall of the shell 1, and a plurality of wire grooves 14 are opened on the top surface of the wiring frame 2. A plurality of negative pressure chambers 4 are opened in the wiring frame 2 along the direction of the wire grooves 14. The plurality of negative pressure chambers 4 are not connected to each other. A piston 5 is slidably connected in the negative pressure chamber 4. The end of the piston 5 away from the communication device 3 is fixedly connected to a cylinder 6. The end of the cylinder 6 away from the piston 5 is commonly connected to a pull plate 8. An air hole 7 is opened at the bottom end of the wire groove 14. The air hole 7 passes through the top of the wiring frame 2 and connects the negative pressure chamber 4 with the outside.

[0024] During specific implementation, multiple wiring racks 2 and communication equipment 3 are set up inside the shell 1. When the operator needs to fix the cable, the cable is embedded in the wire groove 14 on the wiring rack 2. The wire groove 14 is an arc-shaped groove with an excellent arc cross-section. The contact part of the wire groove 14 and the cable is made of rubber. After the cable is placed in the wire groove 14, the part of the wire groove 14 that passes over the center of the cable can fix the cable. The air hole 7 is located at the bottom of the wire groove 14. At this time, the cable completely covers the air hole 7, forming a sealed environment together with the inside of the negative pressure chamber 4. At this time, the pull plate 8 is pulled away from the shell 1, thereby driving the cylinder 6 and the active part fixedly connected to the cylinder 6. The plug 5 moves in the direction away from the shell 1, and the air pressure in the negative pressure chamber 4 becomes smaller, which causes adsorption of the cable placed above the air hole 7, further fixing the cable, and completing the adsorption and fixation of the cable. When replacing or repairing the cable, the operator can push the pull plate 8 back into the negative pressure chamber 4 to release the adsorption of the cable by the air hole 7. At this time, the cable can be taken out for corresponding operations. It is only necessary to place the cable in the cable trough 14 of the wiring rack 2, and by pulling the pull plate 8, the cable is quickly adsorbed and fixed by utilizing the negative pressure effect generated by the negative pressure chamber 4. This process does not require additional fixing tools or complicated operations, which significantly improves the efficiency of cable assembly.

[0025] See Figure 3-Figure 6A sliding rod 9 is slidably inserted into the inside of the cylinder 6, and a pull plate 8 is fixedly connected to the end of the sliding rod 9 away from the piston 5. The other end of the sliding rod 9 is fixedly connected to the limiting block 10. The top and bottom ends of the outer arc surface of the cylinder 6 are provided with limiting grooves 11. An outer side wall of the outer shell 1 is fixedly connected to the limiting assembly. The limiting assembly includes two limiting plates 12. A card plate 13 is slidably connected between the two limiting plates 12. The card plate 13 is clamped with the limiting groove 11. There are two limiting assemblies.

[0026] After the user has fixed the cable, the two relative clamping plates 13 can be moved toward the direction of the cylinder 6 so that the clamping plates 13 are engaged with the limiting grooves 11 opened on the cylinder 6. The clamping plates 13 cooperate with the pressure difference to fix the cylinder 6 to ensure the stable adsorption of the air holes 7. Then, the pull plate 8 is pushed to push the sliding rod 9 that is completely exposed outside the shell 1 into the cylinder 6, reducing the protruding part of the distribution frame outside the shell 1 to prevent unintentional touch by unrelated personnel and reduce safety risks.

[0027] See Figure 2 There are multiple air holes 7, and multiple air holes 7 are evenly and linearly arranged at the bottom of the wire trough 14 along the direction of the wire trough 14. The design of multiple air holes 7 enables the cables to be fixed on the wiring rack 2 more stably.

[0028] See Figure 1 The shell 1 is connected to a movable door 15 by a hinge, and a plurality of heat dissipation holes 16 are provided at the bottom of the shell 1. The movable door 15 connected by the rotation of the shell 1 facilitates the later maintenance and management of the wiring frame. The heat dissipation holes 16 facilitate the exchange of heat from the cables inside the shell 1 with the outside world, thereby increasing the service life of the cables.

[0029] Working principle: When the user uses the distribution frame to fix and assemble the optical fiber, the user places the cable in the cable groove 14 opened on the wiring frame 2, pulls the pull plate 8 to move away from the outer shell 1, and then drives the slide bar 9 to move to the outside of the outer shell 1. The slide bar 9 slides in the cylinder 6 until the slide bar 9 drives the limit block 10 to abut against the inner wall of the cylinder 6, and then drives the cylinder 6 and the piston 5 fixedly connected to the cylinder 6 to move away from the outer shell 1. The air pressure in part of the negative pressure chamber 4 becomes smaller, and the cable placed above the air hole 7 is adsorbed. After the cable is adsorbed and fixed, the cable connector can be connected to the communication equipment 3 to realize communication transmission.

[0030] After the user has fixed the cable, the two relative clamping plates 13 can be moved toward the direction of the cylinder 6 so that the clamping plates 13 are engaged with the limiting grooves 11 opened on the cylinder 6. The clamping plates 13 cooperate with the pressure difference to fix the cylinder 6 to ensure the stable adsorption of the air holes 7. Then, the pull plate 8 is pushed to push the sliding rod 9 that is completely exposed outside the shell 1 into the cylinder 6, reducing the protruding part of the distribution frame outside the shell 1 to prevent unintentional touch by unrelated personnel and reduce safety risks.
