Description

Technical Field

[0001] This utility model belongs to the field of communication signal transmission technology, specifically relating to a 1152-core 2U high-density optical cable assembly. Background Technology

[0002] The problem of insufficient cabling density in traditional optical fiber assemblies is particularly prominent in data center applications. Data center rack space is limited, and due to structural design limitations, traditional optical fiber assemblies struggle to achieve efficient integration of large-scale optical fibers, resulting in low fiber capacity per unit space. This deficiency directly restricts the expansion and upgrade capabilities of data centers, failing to meet the ever-increasing demands for high-density cabling.

[0003] Currently, conventional drawer-type optical cable assemblies lack effective isolation and fixing design between their various branches. When one layer is pulled out for installation or maintenance, other cabling layers are easily pulled out as well. This not only increases the difficulty of the installation process and reduces installation efficiency, but may also lead to accidental pulling or damage to the optical fiber link, causing great inconvenience to subsequent maintenance work and even affecting the stability of data transmission. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model provides a 1152-core 2U high-density optical cable assembly, which enables modular cabling management of the optical cable, and the cabling layer box, in conjunction with a push-pull component, provides an unlocking function.

[0005] The technical effects to be achieved by this utility model are realized through the following aspects: This utility model provides a 1152-core 2U high-density optical cable assembly, comprising: A wiring layer box includes a front-end module and two slide rails, the two slide rails being respectively mounted on both sides of the wiring layer box. The front-end module is provided with several adapters; and A guide rail module is installed inside the optical distribution box. The guide rail module includes a pair of guide rail components. Each of the two guide rail components has a sliding groove on its opposite side. The sliding groove extends from the front end of the guide rail component to the rear end of the guide rail component. The guide rail is slidably connected to the sliding groove. The guide rail is movably connected to a push-pull member. The guide rail has a locking hole at its rear end near the slide groove. The slide rail has a snap-fit ​​member that mates with the locking hole. The push-pull member is used to push the snap-fit ​​member out of the locking hole.

[0006] In some implementations, the snap-fit ​​is mounted on the slide rail on the side away from the wiring box and located at the rear end of the slide rail, and the snap-fit ​​is a flexible boss.

[0007] In some implementations, the elastic boss includes a limiting boss and an elastic element, and the limiting boss is connected to the slide rail through the elastic element.

[0008] In some implementations, the limiting boss is provided with a first locking part and a second locking part, the first locking part is inclined, and the second locking part is arranged perpendicular to the extension direction of the slide rail.

[0009] In some implementations, the push-pull member is provided with a snap-fit ​​groove. When the wiring box is in its initial state, the snap-fit ​​groove is positioned opposite to the lock hole. The lock hole is provided with a guide slope that cooperates with the first snap-fit ​​part. The second snap-fit ​​part is used to abut against the inner wall of the snap-fit ​​groove.

[0010] In some implementations, the guide rail has a receiving cavity with one end open, the push-pull member is installed in the receiving cavity, and the push-pull member is movably connected to the guide rail; the end of the push-pull member away from the snap-fit ​​groove is an unlocking part, and the unlocking part extends out of the receiving cavity.

[0011] In some implementations, the slide rail is provided with a ball groove corresponding to the slide groove along its length, and a plurality of balls are provided in the ball groove. The opening of the ball groove is smaller than the ball, which is used to limit the movement of the ball.

[0012] In some implementations, the guide rail includes two slide grooves arranged opposite each other, and the two ball grooves are respectively located on the upper and lower contact surfaces of the slide rail.

[0013] In some implementations, the inner wall of the guide rail is provided with a guide flange that is adapted to the ball groove.

[0014] In some implementations, the guide rail module includes multiple pairs of guide rail components stacked vertically.

[0015] In summary, this utility model has at least the following advantages: This utility model provides a 1152-core 2U high-density optical cable assembly, assembled in an optical distribution box, to achieve modular cabling management of optical cables. The optical cable is integrated in the cabling layer box and connected via an adapter from the front-end module. Through the sliding engagement of the guide rail module and the cabling layer box, combined with the locking structure of the locking holes and snap-fit ​​components, the pull-out cabling layer can be independently pulled out and locked, preventing accidental removal of the cabling layer box and ensuring the stability of data transmission. The sliding connection design of the guide rail and the slide groove ensures the smoothness of the pulling process, while the engagement of the locking holes and snap-fit ​​components can firmly fix the cabling layer box in the non-operational state, preventing the optical cable link from being pulled or damaged due to accidental sliding. This improves the convenience and operational efficiency of cabling installation and maintenance. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0022] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0023] Example 1: Please see Figure 1 and Figure 2This utility model discloses a structure for a 1152-core 2U high-density optical cable assembly, used for assembly in an optical distribution box. It includes: a cabling layer box 1, comprising a front-end module 11 and two slide rails 12, the two slide rails 12 being respectively installed on both sides of the cabling layer box 1; the front-end module 11 having several adapters 111; and a guide rail module 2, installed in the optical distribution box. The guide rail module 2 includes a pair of guide rail components 21, each guide rail component 21 having a groove 211 on its opposite side, the groove 211 extending from the front end to the rear end of the guide rail component 21, the slide rail 12 being slidably connected to the groove 211; wherein, the guide rail component 21 is movably connected to a push-pull component 22, the guide rail component 21 having a locking hole 212 near the rear end of the groove 211, the slide rail 12 having a snap-fit ​​component 13 cooperating with the locking hole 212, and the push-pull component 22 being used to push the snap-fit ​​component out of the locking hole 212.

[0024] Specifically, the 1152-core 2U high-density optical cable assembly includes a cabling box 1 and a guide rail module 2. The cabling box 1 is used to integrate optical cables 3. The cabling box 1 has a box-like structure. An adapter 111 for connecting optical cables 3 is provided on the front module 11 of the cabling box 1. Slide rails 12 are installed on both sides. The guide rail module 2 is fixedly installed inside the optical distribution box and can be assembled according to layout requirements. The guide rail module 2 includes a pair of guide rail components 21, which are horizontally positioned opposite each other on the side inside the optical distribution box. The guide rail components 21 have sliding grooves 211. The cabling box 1 is slidably connected by the slide rails 12 and the sliding grooves 211 on the guide rail components 21, which facilitates maintenance personnel to pull out and replace cables for maintenance and repair operations.

[0025] The guide rail 21 is provided with a lock hole 212, and the slide rail 12 is provided with a snap-fit ​​component 13. The slide rail 12 is snapped into the lock hole 212 through the snap-fit ​​component 13, so that the wiring box 1 can be locked and fixed, preventing the wiring box 1 from sliding out of the cabinet due to non-operation. The guide rail 21 is also provided with a push-pull rod, and the push-pull component 22 is used to push the snap-fit ​​component 13 out of the lock hole 212, so that the wiring box 1 can be unlocked and pulled out.

[0026] In addition, to avoid abnormalities during the locking process of the wiring layer box 1, the guide rail components 21 are all equipped with pull-out components and locking holes 212. Through the symmetrical design of the locking holes 212 and pull-out components on both sides, the force during the locking operation is evenly distributed on both sides of the wiring layer box 1, avoiding the slide rail 12 from getting stuck with the slide groove 211 or wear caused by the force on one side. In some embodiments, one of the guide rail components 21 is equipped with a pull-out component and a corresponding locking hole 212, and the corresponding side of the wiring layer box 1 is equipped with a snap-fit ​​component 13, so that the wiring layer box 1 is locked by one side.

[0027] Understandably, in the initial state, the wiring box 1 is located inside the guide rail module 2. The latching pieces 13 on both sides of the wiring box 1 engage with the locking holes 212 to achieve locking and fixation. When maintenance personnel need to perform maintenance operations, they can pull or press the push-pull piece 22 to push out the latching pieces 13 inside the locking holes 212, thereby unlocking the wiring box 1 and allowing it to be pulled and moved along the slide rail 12 on the slide groove 211. When maintenance personnel need to lock the wiring box 1, they can push the wiring box 1 to the bottom and then press or pull the push-pull piece 22 to remove the latching pieces 13 from the push-pull piece 22, allowing them to engage with the locking holes 212 and thus locking the wiring box 1.

[0028] It is worth noting that the optical cable 3 located in the optical distribution box is placed in the cabling layer box 1 and connected to the plug end of the adapter 111. The front-end module 11 has multiple side-by-side mounting holes for assembling various types of adapters 111. The adapter 111 can be, but is not limited to, FC type fiber optic adapter, SC type fiber optic adapter, LC type fiber optic adapter and ST type fiber optic adapter. The model selection of the adapter 111 can be determined according to the actual situation, and this application does not limit it here.

[0029] In this embodiment, the 1152-core 2U high-density optical cable assembly can be independently integrated through the design of the cabling layer box 1, so that the optical cables 3 in the optical distribution box can be neatly planned for cabling. In addition, the sliding connection between the slide rail 12 and the slide groove 211, combined with the locking function of the snap-fit ​​component 13 and the lock hole 212, enables the cabling layer box 1 to adopt an independent pull-out design. The independent locking function eliminates interference from other layers, while the guide rail module 2 can be directly fixed in the optical distribution box. The equipment layout can be adjusted according to the actual situation, reducing the modification cost.

[0030] Example 2: This embodiment is a further structural optimization of the 1152-core 2U high-density optical cable assembly of this utility model. Please refer to [link / reference]. Figure 2 and Figure 3 .

[0031] In some embodiments, the snap-fit ​​13 is mounted on the slide rail 12 on the side away from the wiring layer box 1 and located at the rear end of the slide rail 12. The snap-fit ​​13 is an elastic boss.

[0032] Specifically, a snap-fit ​​element 13 is provided at the rear of the wiring box 1. This snap-fit ​​element 13 is installed on the side of the slide rail 12 adjacent to the guide rail, allowing it to engage with the locking hole 212 on the guide rail. Furthermore, the elastic boss, acting as the snap-fit ​​element 13, utilizes its elasticity to form a tight fit with the locking hole 212. When the push-pull element 22 is pushed into place, the push-pull rod no longer obstructs the locking hole 212, and the elastic boss automatically engages with the locking hole 212 to achieve locking. Moreover, the continuous force generated by the elastic deformation reduces the risk of the wiring box 1 becoming loose due to vibration.

[0033] Understandably, when unlocking is required, the push-pull component 22 pushes the elastic boss out of the lock hole 212, causing the elastic boss to contract under force and disengage from the locked state. The properties of the elastic material ensure that the elastic boss can quickly reset without affecting the next locking operation, eliminating the need for an additional reset structure and simplifying the operation. Furthermore, the elastic boss provides clear tactile feedback when it engages or disengages from the lock hole 212, allowing maintenance personnel to determine whether the lock is in place by touch, without additional observation, thus improving convenience and accuracy in blind operation scenarios.

[0034] In some embodiments, the elastic boss includes a limiting boss and an elastic element, and the limiting boss is connected to the slide rail 12 through the elastic element.

[0035] Specifically, a groove is provided on the slide rail 12 for accommodating the elastic boss. The elastic boss includes a limiting boss and an elastic element. The limiting boss is connected to the slide rail 12 through the elastic element. The elastic force of the elastic element enables the limiting boss to always have a force to pop out of the groove. When the wiring layer box 1 is pushed into the locking position, the limiting boss can be precisely locked into the locking hole 212 of the guide rail 21 under the action of the elastic element to achieve the locking function.

[0036] The method of installing the elastic boss in the groove ensures that the elastic boss will not occupy additional space on the outside of the slide rail 12, thus avoiding an increase in the overall volume of the slide rail 12 due to the protrusion of the elastic boss. When unlocked by the push-pull member 22, the external force acts on the limiting boss to make it retract into the groove. The groove provides the retraction space for the limiting boss, which also makes the process of pulling out the wiring box 1 smoother and reduces jamming.

[0037] In some embodiments, the limiting boss is provided with a first locking part 131 and a second locking part 132. The first locking part 131 is inclined and the second locking part 132 is arranged perpendicular to the extension direction of the slide rail 12.

[0038] Specifically, the limiting boss includes a first locking part 131 and a second locking part 132 along the pulling and moving direction of the wiring layer box 1. The inclined setting of the first locking part 131 achieves a guiding function. When the wiring layer box 1 is pushed in, the edge of the locking hole 212 of the guide rail 21 will first contact the inclined first locking part 131. The inclined surface will convert the axial thrust into a lateral force that causes the limiting boss to retract into the groove, which greatly reduces the operating resistance when pushing in and locking.

[0039] In some embodiments, the push-pull member 22 is provided with a snap-fit ​​groove 222. When the wiring layer box 1 is in the initial state, the snap-fit ​​groove 222 is disposed opposite to the lock hole 212. The lock hole 212 is provided with a guide slope that cooperates with the first snap-fit ​​part 131. The second snap-fit ​​part 132 is used to abut against the inner wall of the snap-fit ​​groove 222.

[0040] Specifically, the push-pull member 22 has a snap-fit ​​groove 222 on the side near the lock hole 212. When the wiring box 1 is in its initial state, i.e., in the locked state, the snap-fit ​​groove 222 is opposite to the lock hole 212, allowing the limiting boss to extend through the lock hole 212 into the snap-fit ​​groove 222 to achieve a snap-fit ​​engagement. The outer surface of the lock hole 212 engages with the inclined surface of the first snap-fit ​​part 131 to form a guide inclined surface, while the second snap-fit ​​part 132 is a vertical plane and abuts against the inner wall of the snap-fit ​​groove 222. When the push-pull member 22 applies force toward the second snap-fit ​​part 132, it pushes the limiting boss toward the first snap-fit ​​part 131. Since the first snap-fit ​​part 131 is inclined and the lock hole 212 has a guide inclined surface that engages with it, the limiting boss is pushed by the push-pull member 22, causing the limiting boss to retract into the groove along the guide inclined surface, thereby pushing the elastic boss out of the lock hole 212.

[0041] In some embodiments, the guide rail 21 is provided with a receiving cavity that is open at one end, and the push-pull member 22 is installed in the receiving cavity and is movably connected to the guide rail 21; the end of the push-pull member 22 away from the snap-fit ​​groove 222 is an unlocking part 221, which extends out of the receiving cavity.

[0042] Specifically, a receiving cavity is provided within the guide rail component 21, with an opening near the front end of the guide rail component 21 connecting to the receiving cavity. The receiving cavity is used to house the push-pull component 22, providing a closed installation space for the push-pull component 22. This effectively isolates external dust particles and other debris, preventing impurities from entering the movement gap of the push-pull component 22 and causing jamming during the pushing and pulling process. An unlocking part 221 is provided on the push-pull component 22, extending outward from the opening of the receiving cavity, allowing maintenance personnel to push and pull it. The movable connection between the push-pull component 22 and the guide rail component 21, combined with the guiding effect of the receiving cavity, allows the force applied to the unlocking part 221 by the maintenance personnel to be more directly transmitted to the locking groove 222, enabling the locking groove 222 to move and misalign with the locking hole 212, thus pushing out the limiting boss within the locking groove 222.

[0043] In this embodiment, elastic bosses are provided on the slide rails 12 on both sides of the wiring layer box 1. These bosses cooperate with the locking holes 212 on the guide rail 21 to achieve the locking function. The limiting boss of the elastic boss provides continuous elastic force through the elastic element, so that the limiting boss can be tightly locked into the locking hole 212 and engaged with the slot on the other side of the locking hole 212. The engaging slot 222 cooperates with the second engaging part 132, and the locking hole 212 cooperates with the first engaging part 131. The operation and maintenance personnel can push and pull the push-pull rod to unlock more directly and efficiently, and also make blind operation judgment more convenient.

[0044] Example 3: This embodiment is a further structural optimization of the 1152-core 2U high-density optical cable assembly of this utility model. Please refer to [link / reference]. Figure 2 and Figure 4 .

[0045] In some embodiments, the slide rail 12 is provided with a ball groove 121 corresponding to the slide groove 211 along the length direction. The ball groove 121 is provided with a plurality of balls. The opening of the ball groove 121 is smaller than the ball, which is used to limit the movement of the ball.

[0046] Specifically, the slide rail 12 is provided with a ball groove 121 for sliding, and a number of balls for rolling are provided in the ball groove 121. The balls are in direct contact with the inner wall of the groove 211 on the guide rail 21. The slide rail 12 and the guide rail 21 are slidably connected through the cooperation of the balls and the groove 211. The sliding action of the wiring layer box 1 is realized by using the rolling friction connection method.

[0047] In some embodiments, the guide rail 21 includes two slide grooves 211, which are arranged opposite each other vertically, and two ball grooves 121 are respectively arranged on the upper and lower contact surfaces of the slide rail 12.

[0048] Specifically, the guide rail 21 has upper and lower opposing grooves 211, while the slide rail 12 also has two ball grooves 121, located on the upper and lower contact surfaces respectively. The bidirectional force design transforms the force on the wiring box 1 during the pulling process from unidirectional support to balanced load-bearing in both directions. This structure can effectively counteract the overturning force caused by uneven distribution of internal optical cables 3 or external collisions, and avoid severe wear or jamming on one side between the slide rail 12 and the grooves 211. Especially when the self-weight is large, it can significantly improve the stability of the overall structure.

[0049] In some embodiments, the inner wall of the guide rail 21 is provided with a guide flange that is adapted to the ball groove 121.

[0050] Specifically, a guide flange is provided on the guide rail 21. The matching structure of the guide flange and the ball groove 121 can form a precise lateral constraint on the slide rail 12, further limiting the left and right offset of the pull-out wiring box 1 during the pull-out process. The constraint effect of this structure makes the contact point between the ball and the slide groove 211 and the ball groove 121 more stable, reducing ball wear or groove deformation caused by local stress concentration, and extending the service life of the sliding structure.

[0051] In some embodiments, the guide rail module 2 includes multiple pairs of guide rail components 21 stacked vertically.

[0052] Specifically, the guide rail module 2 can include multiple pairs of guide rail components 21, with a corresponding cabling layer box 1 installed in each pair of guide rail components 21. The pairs of guide rail components 21 are stacked vertically, allowing for multiple pull-out cabling layers in the vertical space within the optical distribution box. The optical cables 3 installed on each layer are relatively independent and can be combined to form a high-density transmission of 1152 cores at 2U, effectively solving the problem of limited rack space. When the data center needs to be expanded, only additional guide rail components 21 need to be added and stacked, without requiring large-scale modifications to the original structure. Furthermore, the cabling layer boxes 1 of the corresponding layers can be pulled out for inspection, simplifying maintenance.

[0053] In this embodiment, the guide rail module 2 adopts a stacked arrangement of multiple pairs of guide rail components 21 to achieve multi-layer distributed wiring planning, which can meet diverse wiring scenarios. Moreover, each wiring layer box 1 can be locked individually, so it will not accidentally slide out during maintenance without operation. Furthermore, the slide rails 12 on both sides of the wiring layer box 1 adopt a sliding structure with bidirectional force on both the upper and lower sides, which can increase the load-bearing capacity and improve the structural stability during the pulling process.
