Description

Technical Field

[0001] This utility model relates to the field of fiber optic distribution box technology, and in particular to a fiber optic distribution box that is resistant to pulling. Background Technology

[0002] Pull-resistant fiber optic distribution boxes are specialized enclosures used in the field of communication equipment for the centralized connection, distribution, and management of fiber optic lines. They are widely used in residential communities, office buildings, communication base stations, and other scenarios. They provide a safe installation and protection space for fiber optic lines, enabling fiber optic splicing, patch cord connections, and port expansion. Simultaneously, their pull-resistant structure reduces damage to the fiber optics from external forces, ensuring the stability and reliability of communication signal transmission.

[0003] However, existing fiber optic distribution boxes have some shortcomings in practical use: First, some enclosures lack effective anti-pull structures, with fiber optic lines directly inserted inside. When subjected to external force, the fiber optics are prone to breakage or loosening of the interfaces, affecting communication transmission. Second, the internal wiring of most enclosures is messy and disorganized, lacking standardized wiring components. Entangled fiber optics can cause signal attenuation and make it difficult to locate the lines during subsequent maintenance, reducing maintenance efficiency. Third, some enclosures have poor ventilation and heat dissipation. The heat generated by the internal electronic components cannot be dissipated in time, leading to excessively high internal temperatures, affecting the lifespan of the components. At the same time, dust and impurities can easily enter the ventilation openings, causing wiring contamination. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a fiber optic distribution box that is resistant to pulling, which overcomes the shortcomings of the prior art and effectively solves the problems of poor anti-pulling effect, messy internal wiring, and poor ventilation, heat dissipation and dust prevention performance of existing fiber optic distribution boxes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A pull-resistant fiber optic distribution box includes an outer frame, an inner frame inside the outer frame, and pull-resistant components evenly distributed on one side of the bottom inner wall of the inner frame. Each pull-resistant component includes a base and a locking block. The base is fixedly connected to the bottom inner wall of the inner frame, and the locking block is screwed to the top outer wall of the base. A wiring component is provided at the center of the bottom inner wall of the inner frame, and ventilation components are provided on both sides of the outer frame.

[0006] Preferably, the outer wall of one side of the inner frame is provided with equally spaced wire threading sleeves, and an optical fiber protection line is provided through the inner wall of the wire threading sleeves, and the optical fiber protection line is clamped between the base and the card block.

[0007] Preferably, the optical fiber protection line has an internal optical fiber body, and an LC socket is provided on the outer wall of one end of the optical fiber body. The LC socket is installed on the outer wall of the other side of the inner frame.

[0008] Preferably, the wiring assembly includes a U-shaped wiring board and a strip wiring board, wherein wiring grooves are provided on the outer walls of both the U-shaped wiring board and the strip wiring board, the U-shaped wiring board is fixedly connected to the bottom inner wall of the inner frame by screws, the strip wiring board is snapped onto the inner wall of the U-shaped wiring board, and the optical fiber body is inserted into the wiring grooves of the U-shaped wiring board and the strip wiring board.

[0009] Preferably, the ventilation assembly includes a ventilation frame, a dust baffle, an air inlet, and an exhaust outlet. The ventilation frame is installed on the outer walls of both sides of the outer frame, the dust baffle is inclinedly disposed on the inner top wall of the ventilation frame, the air inlet is disposed on one side of the ventilation frame, and the exhaust outlet is disposed on the top of the ventilation frame.

[0010] Preferably, an RJ45 interface is provided at one end of the outer wall on one side of the inner frame.

[0011] Preferably, a power indicator light is provided at one end of the outer wall on the other side of the inner frame, and an LED sensor light for guiding and pulling out the jumper is provided on the top of the outer wall on the other side of the inner frame at the LC socket.

[0012] Preferably, an observation window is provided on the top outer wall of the outer frame.

[0013] The beneficial effects of this utility model are as follows: 1. The anti-pull fiber optic distribution box designed in this paper achieves anti-pull protection for optical fibers through anti-pull components and cable pull sleeves. The cable pull sleeves guide and initially fix the optical fiber protection line. The base of the anti-pull component and the clamp are screwed together to firmly clamp the optical fiber protection line. When external force pulls, the clamping force of the base and the clamp offsets the pulling force, preventing the pulling force from being transmitted to the optical fiber body, preventing the optical fiber from breaking or the interface from becoming loose, and ensuring stable communication transmission. 2. The anti-pull fiber optic distribution box designed in this way allows for the standardized organization of internal wiring components. The wiring slots of the U-shaped wiring board and the strip wiring board work together to allow the main body of the optical fiber to be inserted, which can arrange the wiring in sequence and avoid the fiber optic cable from getting tangled or knotted. The strip wiring board is snapped onto the U-shaped wiring board, which facilitates the disassembly and adjustment of the wiring. During subsequent maintenance, the target line can be quickly located, which significantly improves maintenance efficiency and reduces signal attenuation caused by the tangled wiring. 3. The fiber optic distribution box designed for pull resistance features an optimized ventilation system that improves ventilation, heat dissipation, and dust prevention. The air inlet and outlet of the ventilation frame form an air convection channel, quickly dissipating heat from inside the box and preventing excessive temperature from affecting component lifespan. The tilted dust baffle prevents dust from entering through the ventilation opening, thus preventing dust accumulation and contamination of lines and components. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-5 Example 1: A fiber optic distribution box with anti-pull protection includes an outer frame 1, an inner frame 2 inside the outer frame 1, and anti-pull protection components 3 evenly distributed on one side of the bottom inner wall of the inner frame 2. The anti-pull protection components 3 include a base 31 and a locking block 32, wherein the base 31 is fixedly connected to the bottom inner wall of the inner frame 2, and the locking block 32 is screwed to the top outer wall of the base 31.

[0018] The above-described design features an outer frame 1 made of cold-rolled steel plate with a powder-coated surface, providing excellent corrosion and impact resistance. The inner frame 2 is made of aluminum alloy, which is lightweight yet strong, providing a stable foundation for the various components. In the anti-pull assembly 3 at the bottom of the inner frame 2, the base 31 is a rectangular plastic block fixed to the inner frame 2 with screws. The top has an arc-shaped groove that engages with the arc-shaped protrusion of the clamping block 32, forming a clamping space compatible with the fiber optic protection cable 7. The clamping block 32 is bolted to the base 31; tightening the bolts clamps the fiber optic protection cable 7, and the clamping force is adjustable to accommodate fiber optic protection cables 7 of different diameters.

[0019] In embodiment 2, a wiring assembly 4 is provided at the center of the bottom inner wall of the inner frame 2. The wiring assembly 4 includes a U-shaped wiring board 41 and a strip wiring board 42. Wiring grooves are provided on the outer walls of both the U-shaped wiring board 41 and the strip wiring board 42. The U-shaped wiring board 41 is fixedly connected to the bottom inner wall of the inner frame 2 by screws, and the strip wiring board 42 is snapped onto the inner wall of the U-shaped wiring board 41. The optical fiber body 8 is inserted into the wiring grooves of the U-shaped wiring board 41 and the strip wiring board 42.

[0020] With the above solution, in the wiring assembly 4 at the bottom center of the inner frame 2, the U-shaped wiring board 41 is made of plastic and is fixed to the inner frame 2 with screws. Its wiring groove is semi-circular with a spacing of 10mm, which can accommodate multiple optical fiber bodies 8. The strip wiring board 42 is also made of plastic. The wiring groove at the bottom corresponds one-to-one with the wiring groove of the U-shaped wiring board 41. After being snapped onto the U-shaped wiring board 41, it forms a closed wiring channel, which not only fixes the optical fiber body 8, but also prevents the line from falling off.

[0021] In embodiment 3, ventilation components 5 are provided on both sides of the outer wall of the outer frame 1. The ventilation components 5 include a ventilation frame 51, a dust baffle 52, an air inlet 53 and an exhaust outlet 54. The ventilation frame 51 is installed on both sides of the outer wall of the outer frame 1, the dust baffle 52 is inclinedly arranged on the top inner wall of the ventilation frame 51, the air inlet 53 is arranged on one side of the ventilation frame 51, and the exhaust outlet 54 is arranged on the top of the ventilation frame 51.

[0022] With the above-described design, the ventilation components 5 on both sides of the outer frame 1 include a ventilation frame 51 made of plastic, screwed to the outer frame 1, an air inlet 53 on one side consisting of an array of circular through holes, and an exhaust outlet 54 on the top, which is a long, narrow opening, forming an upward and downward convection ventilation channel to improve heat dissipation efficiency. The dust baffle 52 is made of plastic, tilted at a 45° angle, and installed on the inner top wall of the ventilation frame 51, blocking most dust from entering without affecting airflow.

[0023] The inner frame 2 has equidistantly distributed cable sleeves 6 on one side of the outer wall, and an optical fiber protection line 7 is installed through the inner wall of the cable sleeve 6. The optical fiber protection line 7 is clamped between the base 31 and the card block 32. An optical fiber body 8 is installed inside the optical fiber protection line 7, and an LC socket 9 is installed on the outer wall of one end of the optical fiber body 8. The LC socket 9 is installed on the other side of the outer wall of the inner frame 2.

[0024] With the above solution, the cable sleeve 6 on one side of the inner frame 2 is made of rubber with a smooth inner wall, which can reduce friction damage when the fiber optic protection cable 7 is inserted, and at the same time play a sealing role to prevent dust from entering the box. The fiber optic body 8 is inserted into the wiring channel and arranged in sequence. After entering the box from the cable sleeve 6, it is fixed by the anti-pull component 3, and then guided to the LC socket 9 by the wiring component 4. The route is clear and easy to manage and maintain.

[0025] An RJ45 interface 10 is provided at one end of the outer wall of one side of the inner frame 2, a power indicator light 11 is provided at one end of the outer wall of the other side of the inner frame 2, and an LED sensor light 12 for guiding and unplugging the jumper is provided on the top of the LC socket 9 on the outer wall of the other side of the inner frame 2.

[0026] With the above solution, the RJ45 interface 10 (model: RJ45-8P8C) on one side of the inner frame 2 is used for network signal connection, and the power indicator light 11 (model: LED-5MM) on the other side is powered by DC 12V and connected to the power supply through an electrical signal. When it is lit, it indicates that the cabinet is powered on normally. The LED sensor light 12 (model: IR-LED-3W) is an infrared sensor and is powered by DC 5V. When a hand is close to the LC socket 9, the sensor triggers the light to guide the jumper plugging and unplugging operation, improving the ease of use.

[0027] An observation window 13 is provided on the top outer wall of the outer frame 1.

[0028] With the above solution, the observation window 13 at the top of the outer frame 1 is a transparent acrylic plate with a thickness of 5mm. It has good light transmission and is convenient for observing the fiber optic connection status and component operation inside the box. Simple faults such as loose lines can be quickly checked without opening the box, reducing the number of times the box needs to be opened and reducing the risk of dust entering.

[0029] Working principle: When using, first fix the outer frame 1 in the designated installation position, open the outer frame 1, pass the fiber optic protection cable 7 through the cable sleeve 6 on one side of the inner frame 2, put it into the base 31 of the anti-pull assembly 3, tighten the bolts of the clamp 32, and clamp and fix the fiber optic protection cable 7.

[0030] Then, organize the internal wiring: pull out the fiber optic body 8 inside the fiber optic protection cable 7, insert it into the wiring groove of the U-shaped wiring board 41 according to the wiring requirements, cover it with the strip wiring board 42 and tighten it to make the fiber optic body 8 arranged in a standardized manner, and then connect one end of the fiber optic body 8 to the LC socket 9. If network connection is required, it can be connected to the network cable through the RJ45 interface 10.

[0031] After the power is turned on, the power indicator light 11 lights up, indicating that the cabinet is powered on normally; the heat generated by the operation of the electronic components inside the cabinet is discharged through the convection channel formed by the air inlet 53 and the exhaust outlet 54 of the ventilation assembly 5, and the dust baffle 52 prevents dust from entering; when the jumper wire of the LC socket 9 is plugged or unplugged, the LED sensor light 12 lights up after sensing the hand approaching, providing lighting guidance.

[0032] During routine maintenance, the status of the wiring inside the box can be observed through the observation window 13. If the wiring needs to be adjusted, the strip wiring board 42 can be removed for operation. When the fiber optic protection line 7 is pulled by external force, the base 31 and the clip 32 of the anti-pull component 3 clamp and fix it to prevent damage to the fiber optic body 8, ensuring the safety of the line and the stability of communication throughout the process.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
