Description

Technical Field

[0001] This invention relates to the field of network cabinet technology, and in particular to a cable fixing structure for network cabinets. Background Technology

[0002] In the field of network communication, network cabinets serve as the core carrier for data transmission and equipment operation, integrating a large number of communication cables and electronic devices. The stable connection and orderly layout of these cables directly affect the signal transmission quality of the network system and the reliability of equipment operation. Cables within the cabinet not only need to be precisely connected to various interfaces, but also need to withstand interference factors such as vibration and external pulling forces during long-term use. Therefore, securing and protecting the cables is a crucial aspect of ensuring the stable operation of the network cabinet.

[0003] Existing network cabinet cable fixing methods mostly rely on basic structures such as cable ties and clips. After connecting the cables to the internal component sockets of the cabinet, the cables are simply secured externally, lacking specific locking measures for the cable connectors. With this method, cables are prone to shaking when subjected to external forces or vibrations within the cabinet, leading to loose connectors and sockets, causing unstable or even interrupted signal transmission. Furthermore, the lack of effective constraint results in a messy cable layout, increasing maintenance difficulty and potentially causing insulation damage due to cable compression.

[0004] Therefore, to address the above problems, a cable fixing structure for network cabinets is proposed. Summary of the Invention

[0005] To overcome the above deficiencies, this invention provides a cable fixing structure for network cabinets, aiming to improve the problem that some network cabinets lack cable end locking structures in the prior art, which leads to easy shaking of connectors and messy cable layout.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cable fixing structure for a network cabinet includes a cabinet body, the cabinet body having multiple sets of mounting brackets inside, mounting bases on the inner side of the mounting brackets, and multiple cable fasteners on the rear side of the mounting bases.

[0008] The cable fastener includes a housing, a connector, and a cable tie. The outer side of the housing is mounted on the rear side of the mounting base. The cable tie is provided at the front end of the housing, and the connector is provided at the rear end of the housing.

[0009] The cable harness includes two clamping blocks slidably connected inside the housing. A cable harness ring one and a cable harness ring two are respectively provided on the adjacent side of the two clamping blocks. A limit plate is fixedly connected to the outer end of the clamping block. Multiple compression springs are fixedly connected between the inner side of the limit plate and the outer side of the housing. A rotating shaft is rotatably connected inside the front end of the housing. An actuating rod is fixedly connected to the outer side of the rotating shaft.

[0010] As a further description of the above technical solution:

[0011] Both ends of the starter rod are provided with contact balls, and the contact balls located on the outside of the outer shell abut against the side extension end of the limiting plate;

[0012] As a further description of the above technical solution:

[0013] The outer end of the starter rod is retractable, and a telescopic spring is provided inside the outer end of the starter rod. The front end of the outer shell has an open cavity for allowing the starter rod to rotate.

[0014] As a further description of the above technical solution:

[0015] The first and second wire harnesses can shrink and deform inward, and the shape of the first wire harness is adapted to the inner shape of the second wire harness.

[0016] As a further description of the above technical solution:

[0017] The docking component includes an isolation block that is slidably connected inside the rear end of the outer shell. A return spring is provided between the isolation blocks at adjacent ends of the two outer shells, and a sleeve is provided between the two outer shells. The outer side of the isolation block is slidably connected inside the sleeve. A sliding groove is provided inside the rear end of the outer shell, and a push spring is provided inside the sliding groove. One end of the push spring abuts against the isolation block.

[0018] As a further description of the above technical solution:

[0019] The docking component also includes a limiting ring. One side of the limiting ring is slidably connected to the inner side of the rear end of the outer shell. A pressing block is slidably connected inside the limiting ring, and a shrink ring is provided inside the limiting ring. The shrink ring has a rough surface inside to prevent the pressing block from shaking. One end of the pressing block is fixedly connected to a clamping plate, and both the upper and lower ends of the clamping plate are provided with elastic shrink rolls.

[0020] As a further description of the above technical solution:

[0021] The other end of the clamping block abuts against one end of the isolation block, and the outer side of the clamping block is slidably connected inside the groove;

[0022] As a further description of the above technical solution:

[0023] A fan is installed at the top of the cabinet, and a cable routing hole is installed at the bottom of the cabinet.

[0024] The present invention has the following beneficial effects:

[0025] 1. In this invention, the cable end is securely locked through the coordinated action of the starting rod, limiting plate, clamping block, compression spring, and cable tie ring in the cable tie assembly. When the connector moves forward and collides with the starting rod, the starting rod rotates and retracts to release the constraint on the limiting plate. The compression spring pushes the limiting plate and clamping block to move, causing cable tie ring one and cable tie ring two to close tightly, wrapping the cable connector end and the body, forming a rigid constraint. This process effectively prevents cable swaying, and together with the connector, it strengthens the cable fixing effect from the end locking stage, ensuring a neat cable layout within the cabinet and providing a reliable cable connection environment for stable equipment operation.

[0026] 2. In this invention, the efficient and precise processing of cable connectors is achieved through the coordinated operation of structures such as the clamping plate, pressing block, isolation block, return spring, and push spring in the docking component. When the cable head is inserted, the elastic shrink coil on the clamping plate expands under force, causing the pressing block to slide and pushing the isolation block outward, allowing the return spring to accumulate potential energy. The isolation block moves back, causing the clamping plate to close, and the elastic shrink coil wraps around the connector to form an elastic clamping force. The limiting ring and shrink ring ensure alignment accuracy. Subsequently, the push spring releases potential energy, pushing the docking component forward, helping the connector to be accurately inserted into the cabinet socket, laying a solid foundation for the stable connection between the cable and the cabinet components, and significantly improving the reliability of the electrical connection.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Reference Figures 1 to 9 This invention provides an embodiment of a cable fixing structure for a network cabinet, comprising a cabinet 1. The cabinet 1 serves as the basic load-bearing structure of the network cabinet, providing installation space and support for components such as mounting brackets 2, mounting bases 3, and cable fasteners 4. Multiple mounting brackets 2 are installed inside the cabinet, each supporting the mounting bases 3. Depending on the cable layout and routing, different mounting points are provided for the mounting bases 3 to accommodate various cable fixing requirements. Mounting bases 3 are located on the inner side of the mounting brackets 2, fixing the outer shell 41 of the cable fasteners 4 and providing an installation reference for the cable fasteners 4, ensuring stable assembly within the cabinet. Multiple cable fasteners 4 are located on the rear side of the mounting bases 3. Each cable fastener 4, as a core functional component, integrates an outer shell 41, a connector 42, and a cable bundle 43. Through the coordinated operation of these components, precise cable fixing and connection are achieved, completing the entire cable fixing process from cable introduction to end locking and connection with cabinet components. A fan 6 is installed at the top of cabinet 1 to create a well-ventilated environment and prevent the cables from accumulating heat and affecting equipment operation. Cable routing holes 5 are installed at the bottom of cabinet 1 to guide cables into the cabinet.

[0040] The cable fastener 4 includes a housing 41, a connector 42, and a cable tie 43. The housing 41 serves as the basic frame of the cable fastener 4, and its outer side is installed on the rear side of the mounting base 3, providing installation space for the connector 42 and the cable tie 43. The front end accommodates the cable tie 43 to lock the cable end, and the rear end is where the connector 42 is arranged to complete the cable connection. The cable tie 43 is located at the front end of the housing 41, and the connector 42 is located at the rear end.

[0041] The docking component 42 includes an isolation block 421 slidably connected inside the rear end of the outer shell 41. In cooperation with the clamping block 425, the return spring 422, and the push spring 423, the isolation block 421 changes position by sliding, accumulating and releasing the potential energy of the return spring 422, and pushing the docking assembly forward under the action of the push spring 423. A return spring 422 is provided between the isolation blocks 421 at adjacent ends of the two outer shells 41. When the isolation block 421 moves outward due to cable insertion, the return spring 422 is stretched, accumulating elastic potential energy, and then releasing the potential energy to cause the isolation block 421 to move back, driving the clamping plate 426 to close. A sleeve 44 is provided between the two outer shells 41, with the outer side of the isolation block 421 slidably connected inside the sleeve 44. The sleeve 44 acts as a guide, ensuring that the movement trajectory of the isolation block 421 is stable when pushed by the clamping block 425 or moved by the return spring 422. A sliding groove is provided inside the rear end of the outer casing 41, and a push spring 423 is installed inside the sliding groove. One end of the push spring 423 abuts against the isolation block 421. When the isolation block 421 moves back and separates from the push spring 423, the compressed push spring 423 releases its elastic potential energy, pushing the isolation block 421 to move towards the front end of the outer casing 41, thereby driving the docking assembly forward. The docking component 42 also includes a limiting ring 424. One side of the limiting ring 424 is slidably connected to the inner side of the rear end of the outer casing 41, and a pressing block 425 is slidably connected inside it. The rough surface of the inner contraction ring 427 restricts the shaking of the pressing block 425 and provides a stable sliding guide for the pressing block 425.

[0042] The other end of the clamping block 425 abuts against one end of the isolation block 421, and its outer side is slidably connected inside the groove. Under the action of the isolation block 421 and the push spring 423, it slides, transmitting force to close the clamping plate 426 or move the docking assembly forward. A shrinkage ring 427 is provided inside the limiting ring 424. The rough surface of the inner side of the shrinkage ring 427 rubs against the outer side of the clamping block 425 to prevent the clamping block 425 from shaking during sliding, ensuring the stability of the clamping block 425's movement. One end of the clamping block 425 is fixedly connected to the clamping plate 426. The upper and lower ends of the clamping plate 426 are provided with elastic shrink coils. When the cable head is inserted, the elastic shrink coils expand under force, causing the clamping block 425 to slide. The isolation block 421 moves back, causing the clamping plate 426 to close. The elastic shrink coils wrap around the connector, forming an elastic clamping force and continuously providing radial clamping force to counteract the axial tension of the cable. Both ends of the clamp 426 are equipped with elastic shrink rolls, which have elastic deformation capabilities. When the cable is inserted, the clamp expands and when the clamp 426 closes, it shrinks to wrap around the connector, forming an elastic clamping force. This not only adapts to the cable insertion action, but also continuously clamps the connector after the connection is made.

[0043] The cable harness 43 includes two clamping blocks 431 slidably connected inside the outer casing 41. Under the action of a limiting plate 434 and a compression spring 435, the clamping blocks 431 slide towards the center, causing the cable harness rings to wrap around the end of the cable connector and the main body, forming a rigid constraint. A cable harness ring 432 and a cable harness ring 433 are respectively provided on adjacent sides of the two clamping blocks 431. The cable harness ring 432 and the cable harness ring 433 can contract and deform inwards, and their shapes are mutually adapted, sliding together with the clamping blocks 431 to tightly wrap around the end of the cable connector and the main body. A limiting plate 434 is fixedly connected to the outer end of the clamping blocks 431. Multiple compression springs 435 are fixedly connected between the inner side of the limiting plate 434 and the outer side of the outer casing 41. The limiting plate 434 is constrained by the contact ball of the starting rod 437 or moves under the action of the compression springs 435, causing the clamping blocks 431 to slide.

[0044] A rotating shaft 436 is rotatably connected to the front end of the outer casing 41. The rotating shaft 436 provides rotational support for the starting rod 437, allowing the starting rod 437 to rotate around it and enter the movable cavity, releasing the constraint on the limiting plate 434. The starting rod 437 is fixedly connected to the outer side of the rotating shaft 436. Contact balls are provided at both ends of the starting rod 437. The outer contact ball abuts against the extended end of the limiting plate 434, constraining the limiting plate 434. When the inner contact ball is impacted by the cable connector, it rotates around the rotating shaft 436 and retracts inward. Contact balls are provided at both ends of the starting rod 437. The contact ball on the outer side of the outer casing 41 abuts against the side extension end of the limiting plate 434, while the inner contact ball is used to collide with the front end of the cable connector, transmitting force to rotate the starting rod 437. The outer end of the starter lever 437 is retractable, and a telescopic spring is installed inside the outer end of the starter lever 437. The telescopic spring provides telescopic capability for the outer end of the starter lever 437, allowing the starter lever 437 to retract inward when rotating, preventing it from jamming against the clamping block 431. The front end of the outer casing 41 has an open cavity for allowing the starter lever 437 to rotate. The open cavity provides rotation space for the starter lever 437, allowing it to enter the cavity when rotating around the pivot 436, thus preventing the starter lever 437 from interfering with other components of the outer casing 41.

[0045] Working principle: When it is necessary to fix the cables in the network cabinet, firstly, the staff will introduce the cables to be fixed into the cabinet 1 through the cable routing hole 5 at the bottom of the cabinet 1. Then, according to the layout and routing of the cables, the corresponding mounting bracket 3 on the inside of the mounting bracket 2 will be selected, and the cables will be fixed using the cable fastener 4.

[0046] The operator first inserts the cable head (including the connector) through the rear opening of the housing 41. At this time, the clamping plate 426 of the mating piece 42 is initially open, and its elastic retraction coil expands to both ends due to the insertion of the cable head. The expansion of the clamping plate 426 causes the clamping block 425 to slide outward along the inner side of the limiting ring 424. The other end of the clamping block 425 pushes the isolation block 421 to move outward against the elastic force of the return spring 422, increasing the distance between the isolation blocks 421 of the two adjacent housings 41. During this process, the outer side of the isolation block 421 slides along the inner wall of the sleeve 44 to ensure a stable movement trajectory.

[0047] When the cable head is fully inserted into the predetermined position, the return spring 422 accumulates elastic potential energy due to the outward movement of the isolation block 421. At this time, the spring force causes the isolation block 421 to move in the opposite direction. The return movement of the isolation block 421 is transmitted to the clamping plate 426 through the pressing block 425, causing the clamping plate 426 to close in the middle. During the reset process, the elastic contraction coils at the upper and lower ends of the clamping plate 426 gradually wrap around the outer surface of the cable connector, forming an elastic clamping force. At the same time, the contraction ring 427 on the inner side of the limiting ring 424 restricts the shaking of the pressing block 425 through the friction between the rough surface and the outer side of the pressing block 425, ensuring the alignment and clamping accuracy of the clamping plate 426 on the cable connector.

[0048] As the isolation block 421 continues to move back, when it separates from the push spring 423, the compressed push spring 423 begins to release its elastic potential energy. The push spring 423 pushes the isolation block 421 towards the front end of the housing 41. This thrust is transmitted through the clamping block 425 to the limiting ring 424 and the clamping plate 426, causing the entire docking assembly (including the clamping plate 426, clamping block 425, limiting ring 424, and cable connector) to slide towards the front end of the housing 41. During this process, the groove provides guidance for the clamping block 425, ensuring that the cable connector moves smoothly forward in a straight line.

[0049] When the cable connector moves forward with the clamping plate 426 to the front end of the housing 41, the front end of the connector collides with the contact ball at one end of the inner side of the starting rod 437. This causes the starting rod 437 to rotate around the pivot 436 and enter the movable cavity. Since the outer end of the starting rod 437 is telescopic and has an internal telescopic spring, it retracts inward while rotating, thus avoiding jamming with the clamping block 431. The rotation of the starting rod 437 causes the contact ball at its outer end to disengage from the side extension end of the limiting plate 434, releasing the constraint on the limiting plate 434. At this time, the compression spring 435, which is in a compressed state, pushes the limiting plate 434 to close in the middle. The limiting plate 434 drives the clamping block 431 to slide inside the housing 41, causing the first cable tie ring 432 and the second cable tie ring 433 to gradually approach each other. Since the cable tie ring 432 and the cable tie ring 433 can shrink and deform inward and their shapes are compatible with each other, when they are closed, they tightly wrap around the end of the cable connector and the cable body, forming a rigid constraint to prevent the cable from shaking.

[0050] As the cable tie 43 locks the cable end, the continuous thrust of the push spring 423 is transmitted to the cable connector through the mating part 42, causing it to continue moving towards the front end of the housing 41. Since the entire cable tie 4 is fixedly connected to the mounting base 3 via the outside of the housing 41, and the mounting base 3 is pre-calibrated with the socket positions of the components inside the cabinet, the cable connector is precisely inserted into the socket of the cabinet component under the pushing force, completing the electrical connection. During this process, the elastic retraction coil of the clamping plate 426 continuously provides radial clamping force, counteracting the axial tension on the cable and ensuring the connection stability between the connector and the socket.

[0051] Throughout the cable fixing process, the fan 6 installed at the top of cabinet 1 operates continuously, creating a good ventilation environment inside cabinet 1 and preventing heat accumulation caused by dense cable arrangement, which could affect the normal operation of the equipment. After all the cables that need to be fixed have been fixed through the cable tie 43 and connector 42 of the cable fastener 4, the entire network cabinet cable fixing structure has achieved effective cable fixing, ensuring that the cable layout inside the network cabinet is neat and the connection is stable, providing a reliable cable connection environment for the normal operation of the equipment inside the cabinet.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
