Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of data center, computer room network wiring, in particular to a rack-mounted distribution box. BACKGROUND

[0002] In modern network infrastructure, rack-mounted distribution boxes are the core equipment for organizing and managing a large number of network cables (such as twisted pair cables, fiber optic jumpers). In order to optimize space utilization and improve maintenance efficiency, the distribution box is usually composed of a plurality of independently drawable fiber storage trays (or called cable organizers, drawer-type cable management trays). This design allows maintenance personnel to pull out the entire fiber storage tray from the rack, thereby easily accessing the rear interfaces and cables, avoiding the difficulties of operating in a narrow space, and facilitating maintenance.

[0003] Currently, the common drawable fiber storage tray structure mainly includes a box body, a sliding rail mechanism, and a distribution module mounted on the front of the box body. The cable enters from the rear of the rack, passes through the vertical cable management slot, and is finally fixed and terminated on the distribution module of the fiber storage tray.

[0004] Although this pull-out design brings convenience, it has a long-standing technical defect that has not been effectively solved: during the pulling out and pushing back of the fiber storage tray, the rear cable will interfere with other cables due to the dynamic change of the path length, which will cause other connectors to loosen or be damaged. The direct pulling force generated during pulling will be transmitted to the connectors (such as RJ45 crystal heads, fiber LC / SC connectors) at both ends of the cable. This continuous or instantaneous pulling force can cause the connector to be slightly pulled out of the switch or organizer port, resulting in poor signal contact, network outage, or performance degradation. In severe cases, it may even damage the clasp or pin of the connector, causing permanent hardware failure. SUMMARY

[0005] The purpose of the present application is to provide a rack-mounted distribution box to solve the problem of fiber cable storage during the pulling out and pushing back of the fiber storage tray.

[0006] The rack-mounted distribution box provided by the present application adopts the following technical solution: a rack-mounted distribution box, characterized by comprising a box body, which is internally divided into an incoming line area, an organizing area, and an outgoing line area, and the organizing area is provided with at least one set of linearly arranged sliding rails; a movable frame capable of moving along the extension direction of the sliding rails;

[0007] a fiber storage tray, comprising a box body and a cover plate, the box body is installed on the movable frame, the cover plate is detachably connected with the box body, a plurality of vertical plates and fixing blocks are arranged in the box body, a fiber storage area is formed between two adjacent vertical plates, and a movable block is arranged in the fiber storage area; a linkage assembly for driving the movement of the movable block;

[0008] The optical fiber enters the fiber container from the entrance of the fiber container, and the optical fiber passes through the moving block. When the moving frame is inserted into the arrangement area, the fiber container moves relative to the box. At this time, the linkage assembly drives the moving block to move, so that the moving block bends the optical fiber into the fiber container area.

[0009] By adopting the above technical scheme, when the maintenance personnel push or pull out the fiber container, the moving frame and the box move relative to each other. This movement is converted into the displacement of the moving block in the fiber container area in real time through the linkage assembly. The moving block can move the optical fiber, and the movement can accurately guide the optical fiber to bend out or release a redundant "U" shaped path in the fiber container area. This is equivalent to providing a dynamic stroke accommodation for the optical fiber, so that the effective working length of the optical fiber from the incoming line area to the outgoing line area can adapt to the change of the pulling process.

[0010] Preferably, the fixed block is arranged at the outgoing port of the fiber container, and the fixed block is provided with a plurality of clamping channels. The clamping channel is provided with a plurality of first deformation members and a plurality of second deformation members. The first deformation member and the second deformation member are arranged on the two side walls of the clamping channel respectively. The top end of the first deformation member is provided with a first abutting surface, and the top end of the second deformation member is provided with a second abutting surface. The first abutting surface and the second abutting surface are inclined in opposite directions. The installation positions of the first deformation members and the second deformation members in the same column are offset.

[0011] By adopting the above technical scheme, the clamping channel on the fixed block constitutes the last controllable passageway before the optical fiber leaves the fiber container. The first deformation member and the second deformation member are arranged in an opposite inclined direction and an offset installation position, forming a "staggered" clamping path. This design can provide a low-resistance and guided channel for the optical fiber when the cover is opened (i.e. in a non-pressed state); and when the cover is closed and pressed, it can achieve multi-point, flexible and reliable clamping and fixing of the optical fiber, effectively preventing the optical fiber from moving or retracting at the outlet when disturbed by external force.

[0012] Preferably, the first deformation member is provided with a first inclined surface and a second inclined surface on the two sides respectively. The vertical inclination angle of the first inclined surface is smaller than the vertical inclination angle of the second inclined surface. The first inclined surface is provided with a first protrusion near the top end position, and the first protrusion and the first inclined surface constitute a pressing area. The second inclined surface is provided with a second protrusion near the middle position, and the second protrusion and the second inclined surface constitute a receiving area.

[0013] By adopting the above technical scheme, the inclined surfaces with different angles on the two sides of the first deformation member produce the expected deformation under different stress states. The pressing area at the top end is mainly used for finally locking the optical fiber, and the receiving area in the middle plays a role in preliminary guiding and pre-pressing during the closing process of the cover. This phased and regional contact control ensures the smoothness and reliability of the clamping process, and avoids sudden stress concentration or scratching on the surface of the optical fiber.

[0014] Preferably, the second deformation member is provided with a third protrusion on one side, and the third protrusion is pressed against the optical fiber when the second deformation member is bent.

[0015] By adopting the above technical solution, the design of the third protrusion increases the contact pressure between the second deformation member and the optical fiber, so that the optical fiber can be clamped more effectively when bent. It cooperates with the pressing area on the first deformation member to exert pressure on the optical fiber from different directions and at different heights, and together forms a stable and multi-point distributed clamping force field, greatly enhancing the stability and anti-loosening ability of clamping.

[0016] Preferably, the cover plate is provided with an abutting portion, and the abutting portion abuts against the first abutting surface and the second abutting surface respectively when the cover plate is closed, so that the first deformation member and the second deformation member are bent towards opposite directions respectively.

[0017] By adopting the above technical solution, the abutting portion of the cover plate drives the first deformation member and the second deformation member to bend towards opposite directions at the same time when closed. The automatic switching of the clamping state is realized, and the operation is extremely simple, efficient and reliable.

[0018] Preferably, the vertical plate is arranged between the fixed block and the entrance of the fiber containing disc, a sliding groove is arranged in the fiber containing area, the sliding groove penetrates the bottom surface of the box body, the moving block can move along the sliding groove, the moving block is detachably connected with a connecting piece, and the connecting piece is connected with the linkage assembly.

[0019] By adopting the above technical solution, the fiber containing area divided by the vertical plate provides storage space for the bending of the optical fiber. The moving block is connected with the outside linkage through the sliding groove and the connecting piece, so that its movement is accurately guided, ensuring that the moving block can smoothly push or pull the optical fiber during the driving process, forming a regular and consistent bending radius, avoiding sharp bends or messy lines, and thereby minimizing the signal attenuation and physical damage of the optical fiber.

[0020] Preferably, the linkage assembly comprises a driving plate, the driving plate is arranged between the moving frame and the fiber containing disc, a plurality of driving grooves are arranged on the driving plate, the projection of the driving groove track path and the projection of the sliding groove track path in the vertical direction intersect, and the connecting piece is slidably connected with the driving groove.

[0021] By adopting the above technical solution, the driving plate is fixed to the moving frame, and the driving grooves thereon intersect with the sliding grooves on the fiber containing disc in projection, forming a clever "motion synthesizer". When the moving frame and the fiber containing disc move relatively, the connecting piece will convert the horizontal straight line motion into the specific and preset track motion of the moving block in the fiber containing area under the constraint of the driving groove, so as to accurately control the bending and releasing of the optical fiber.

[0022] Preferably, the slide rail is divided into deep grooves and shallow grooves according to the depth of the grooves, the moving frame is provided with a first sliding part in sliding connection with the shallow grooves, and the driving plate is provided with a second sliding part in sliding connection with the deep grooves.

[0023] By adopting the above technical scheme, the double-rail design of deep and shallow grooves is the basis for realizing relative movement. The movement of the moving frame and the driving plate is separated: the moving frame runs in the shallow grooves, representing the pulling of the entire unit; and the driving plate runs in the deep grooves and produces relative displacement with the moving frame. It is this relative displacement that becomes the direct power source for the operation of the driving linkage assembly, ensuring that the fiber management mechanism is triggered only when the pulling action occurs.

[0024] Preferably, the incoming line area is provided with a fixer fixedly connected thereto, and the fixer is used for fixing the optical fiber.

[0025] By adopting the above technical scheme, the tension of the optical cable entering from the rear of the rack is absorbed here and will not be transmitted to the rear. This makes the fiber segment inside the fiber container become an independent and controllable "service loop", and all length compensation changes are limited within this loop, improving the accuracy and reliability of management.

[0026] Preferably, the moving frame is provided with a plurality of optical fiber adapters, and the optical fiber is connected to the optical fiber adapters after being arranged by the fiber container.

[0027] By adopting the above technical scheme, the end of the optical fiber after internal arrangement and length compensation is directly terminated to the optical fiber adapters on the moving frame itself. This means that when the entire fiber container unit is pulled out, the adapters and the optical fiber jumpers connected thereto move together, and the optical fiber segment managed by the moving block is adaptively adjusted, completely avoiding direct pulling of the optical fiber connector on the access side, and realizing the ideal effect of "moving while compensating".

[0028] In summary, the present application has the following at least one beneficial technical effect:

[0029] 1. When the maintenance personnel pulls out or pushes in the moving frame, the moving frame and the driving plate produce relative displacement due to the design of the deep and shallow grooves on the slide rail, and this displacement is accurately converted into the synchronous movement of all moving blocks in the fiber container area through the driving plate and the connecting piece. The moving block guides the optical fiber to dynamically form or retract a redundant "U" shape, and this adaptive travel compensation mechanism can effectively absorb the excess length change of the optical fiber due to operation, fundamentally avoiding damage to the optical fiber due to excessive pulling or excessive bending due to redundant accumulation, greatly improving the operation safety and the service life of the optical fiber.

[0030] 2. When the cover is closed, the abutting part forces the first and second deformation members to bend in different directions. The deformation members, through their unique slope and convex structure, exert a multi-point, staggered, distributed clamping force on the optical fiber passing through the clamping channel. This clamping method is not simply rigid compression, but allows the optical fiber to have a small, controlled bend, thereby providing excellent anti-loose and anti-vibration ability while effectively avoiding micro-damage to the optical fiber caused by stress concentration.

DETAILED DESCRIPTION

[0043] The following will be described in detail below with reference to the accompanying drawings. Figure 1 - the accompanying drawings Figure 11 The present application will be described in further detail.

[0044] The embodiment of the present application discloses a rack-mounted distribution box.

[0045] Embodiment 1, referring to Figure 1 and Figure 2 A rack-mounted distribution box comprises a box body 1, a moving frame 2, a fiber storage disc 3 and a linkage assembly 4, the box body 1 is divided into an incoming line area 11, an arrangement area 12 and an outgoing line area 13, in the embodiment 1, 12 groups of slide rails 121 arranged in the vertical direction are fixedly connected to the front and rear inner walls of the arrangement area 12, the moving frame 2 is slidingly connected with the slide rails 121, and the moving frame 2 can be pulled out of the slide rails 121; the box body 1 is fixedly connected with a fixed plate 14, and when the moving frame 2 needs to be fixed after being installed to the slide rails 121, the moving frame 2 is fixed to the fixed plate 14 through bolts.

[0046] Referring to Figure 1 , the moving frame 2 is fixedly connected with the fiber storage disc 3, 10 groups of optical fiber adapters 21 are arranged on the moving frame 2, a plurality of fixers 111 are fixedly connected in the incoming line area 11 and the outgoing line area 13, and optical fibers (red lines in the figure represent optical fibers) enter the incoming line area 11, pass through the fixers 111, are arranged in order in the fiber storage disc 3 and are connected with the optical fiber adapters 21, the optical fiber adapters 21 are connected with external optical fibers (blue lines in the figure represent external optical fibers), and the external optical fibers pass through the fixers 111 in the outgoing line area 13 and are output in order. Figure 1 Figure 1

[0047] Referring to Figure 3 and Figure 4 ​​, the fiber container 3 includes a box body 31 and a cover plate 32, the box body 31 is detachably connected with the moving frame 2, in the embodiment, the box body 31 is connected with the moving frame 2 through bolts, the box body 31 is fixedly connected with two fixed blocks 5 and a plurality of vertical plates 6, the box body 31 is provided with an inlet and an outlet, the fixed block 5 is installed at the outlet, a fiber containing area 61 is formed between two adjacent vertical plates 6, and a moving block 62 connected with the linkage assembly 4 is arranged in the fiber containing area 61;

[0048] With reference to Figure 5 and Figure 6 , during the operation of pushing or pulling the fiber container 3, the relative displacement between the moving frame 2 and the box body 1 is accurately transmitted to the moving block 62 in the fiber containing area 61 through the linkage assembly 4. The moving block 62 guides the fiber to form or retract a redundant “U”-shaped bend (i.e. the red wire path in Figure 5 and Figure 6 ) in the fiber containing area 61 through its directional displacement. Essentially, this mechanism provides a dynamic travel compensation mechanism for the fiber, ensuring that the effective working length of the fiber between the inlet area 11 and the outlet area 13 can be adaptively adjusted during the operation of the fiber container 3.

[0049] With reference to Figure 7 and Figure 8 , the fixed block 5 is fixedly connected with two groups of first deformation members 51 (each group is arranged in an array of 6), two groups of second deformation members 52 (each group is arranged in an array of 6), and two groups of intermediate blocks 53 (each group is arranged in an array of 6), a clamping channel 54 (shown by the blue line in Figure 8 ) is formed between adjacent two first deformation members 51, adjacent two second deformation members 52, and adjacent two intermediate blocks 53. The clamping channel 54 is a “staggered” clamping path. The cover plate 32 is provided with an abutting portion 321, when the cover plate 32 is closed, the abutting portion 321 abuts against the top ends of the first deformation members 51 and the second deformation members 52, so that the first deformation members 51 and the second deformation members 52 are bent in different directions, which can clamp the small-amplitude bend of the fiber, and the clamping effect is better.

[0050] With reference to Figure 8In the middle a-a schematic diagram, and in the direction of the coordinate in the figure as an example, the top end of the first deformation piece 51 is provided with a first abutting surface 515, the left side of the first abutting surface 515 is higher than the right side, so that when the abutting part 321 is in contact with the first abutting surface 515, the first deformation piece 51 can be curved to the left and down. The left side of the first deformation piece 51 is provided with a first inclined surface 511, and the right side is provided with a second inclined surface 512. The vertical inclination angle of the first inclined surface 511 is smaller than the vertical inclination angle of the second inclined surface 512. The first inclined surface 511 is provided with a first protrusion 513 near the top end position, and the first protrusion 513 and the first inclined surface 511 form a compression area 516. The second inclined surface 512 is provided with a second protrusion 514 near the middle position, and the second protrusion 514 and the second inclined surface 512 form a receiving area 517. When the first deformation piece 51 is curved to the left and down, the compression surface makes the optical fiber bend to the left with a small amplitude, and the receiving area 517 provides space for the optical fiber to move.

[0051] Reference Figure 8 In the middle b-b schematic diagram, the top end of the second deformation piece 52 is provided with a second abutting surface 522, the right side of the second abutting surface 522 is higher than the left side, so that when the abutting part 321 is in contact with the second abutting surface 522, the second deformation piece 52 can be curved to the right and down, so that the optical fiber can be bent to the right with a small amplitude. The right side of the second deformation piece 52 is provided with a third protrusion 521, and when the second deformation piece 52 is curved, the third protrusion 521 compresses the optical fiber.

[0052] By bending the optical fiber in different directions by the first deformation piece 51 and the second deformation piece 52, a stable and multi-point distributed clamping force field is formed, which greatly enhances the stability and anti-loose ability of clamping.

[0053] Reference Figure 9 And Figure 10 The bottom surface of the fiber containing area 61 is provided with a through sliding groove 63, and the moving block 62 is slidably connected with the sliding groove 63. The moving block 62 partially penetrates the sliding groove 63 to the other side. The moving block 62 is fixedly connected with a connecting piece 621 through a bolt. The connecting piece 621 prevents the moving block 62 from being separated from the sliding groove 63.

[0054] The bottom surface of the box body 31 is provided with a stand 71, and the stand 71 is fixedly connected with a bottom plate 7. The bottom plate 7, the stand 71 and the moving frame 2 are connected through bolts. The bottom plate 7 is provided with a sliding protrusion 72. In the embodiment 1, the sliding protrusion 72 is in the form of an elongated rod. The sliding protrusion 72 is slidably connected with a driving plate 8. The driving plate 8 is provided with a driving groove 81. The trajectory path of the driving groove 81 intersects with the vertical projection of the trajectory path of the sliding groove 63. The driving groove 81 is slidably connected with the connecting piece 621. Thus, when the driving plate 8 moves, all the moving blocks 62 can move synchronously.

[0055] Reference Figure 11, the bottom plate 7 is fixedly connected with a stop block 74, the stop block 74 is provided with a spring 73 between the driving plate 8, the slide rail 121 is divided into a deep groove 1212 and a shallow groove 1211 according to the depth of the groove, the moving frame 2 is provided with a first sliding part 22 slidably connected with the shallow groove 1211, and the driving plate 8 is provided with a second sliding part 82 slidably connected with the deep groove 1212; the moving frame 2 runs in the shallow groove 1211, representing the pulling / placing of the whole unit; and the driving plate 8 is relatively displaced with the moving frame 2 under the blocking action of the deep groove 1212, so that the moving block 62 moves to bend the optical fiber to the fiber storage area 61, at this time, the spring 73 is compressed and stores elastic performance;

[0056] When the moving frame 2 is pulled, the spring 73 releases the elastic performance, so that the moving block 62 moves to release the bent optical fiber.

[0057] The implementation principle of the rack-mounted distribution box in the embodiment of the application is as follows: when a maintenance personnel needs to operate the fiber storage disc 3, the moving frame 2 is pulled out or pushed in to move along the slide rail 121. In this process, the moving frame 2 and the box body 1 are relatively displaced. Since the moving frame 2 runs in the shallow groove 1211 of the slide rail 121 through the first sliding part 22, and the driving plate 8 runs in the deep groove 1212 of the slide rail 121 through the second sliding part 82, the blocking action of the deep groove 1212 on the driving plate 8 causes the driving plate 8 to relatively move with the moving frame 2.

[0058] The relative movement forces the driving plate 8 to displace against the elastic force of the spring 73, and the spring 73 is compressed to store energy. The driving groove 81 on the driving plate 8 converts the horizontal displacement into the directional sliding of the moving block 62 in the sliding groove 63 of the fiber storage area 61 through the connecting piece 621 slidably connected therewith. All the moving blocks 62 realize synchronous movement through the driving plate 8.

[0059] The directional displacement of the moving block 62 guides the optical fiber between the incoming line area 11 and the outgoing line area 13 to form or retract a redundant “U”-shaped bend in the fiber storage area 61. This dynamic travel compensation mechanism adaptively adjusts the effective working length of the optical fiber, effectively avoiding damage, excessive bending or relaxation of the optical fiber due to insufficient or excessive length allowance when the fiber storage disc 3 is pulled out or pushed in.

[0060] When the moving frame 2 reaches the predetermined position and is locked and fixed through the bolt and the fixed plate 14, the operation is completed. At this time, if the spring 73 is in a compressed state, the stored elastic potential energy can assist in releasing next time the moving frame 2 is pulled out, to drive the moving block 62 to move reversely, to help the optical fiber to be smoothly bent back.

[0061] When the cover plate 32 is closed, the abutting part 321 presses the top ends of the first and second deformation members 51 and 52, causing them to elastically bend in different directions (e.g. left and right directions) in a controllable manner. The bending of the first and second deformation members 51 and 52 is achieved by the inclined surfaces and protrusions on the side surfaces of the first and second deformation members 51 and 52, which exert a multi-point distributed and directionally staggered clamping force field on the optical fiber passing through the clamping channel 54, thereby stably holding and effectively limiting the optical fiber, preventing the optical fiber from loosening due to vibration or movement inside the box body 1, and avoiding excessive bending stress.

[0062] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Any equivalent changes made on the basis of the structure, shape, and principle of the present application shall be encompassed within the protection scope of the present application.
