Description

Technical Field

[0001] This application relates to the field of optical communication equipment technology, and in particular to a pull-out wiring device. Background Technology

[0002] Fiber optic patch panels are wiring connection devices between optical cables and optical communication equipment or between optical communication equipment. They also serve to fix communication cables and are an indispensable part of solving data transmission relay.

[0003] As the demand for network information and data exchange continues to increase, the requirements for communication equipment carriers are becoming more and more targeted. The number of communication cables connected to patch panels in most computer rooms is also increasing day by day. The wiring connections of communication cables located behind the patch panel are messy and have poor maintainability. Summary of the Invention

[0004] To improve the ease of maintenance of fiber optic patch panels, this application provides a pull-out patch panel device.

[0005] This application provides a retractable wiring device, which adopts the following technical solution: A pull-out wiring device includes an outer casing and a pull-out bracket; the outer casing has a forward-facing opening; both the outer casing and the pull-out bracket have two sides; the pull-out bracket is located between the two sides of the outer casing; the side of the outer casing is provided with an outer slide rail, and the side of the pull-out bracket is provided with an inner slide rail; a slider is connected between the pull-out bracket and the outer casing; one side of the slider is slidably mounted on the inner slide rail, and the other side is slidably mounted on the outer slide rail; the front end of the outer slide rail extends towards the opening to the front side of the outer casing; a wiring assembly is installed on the front side of the pull-out bracket; the rear end of the inner slide rail is located behind the wiring assembly.

[0006] By adopting the above technical solution, the pull-out shelf can be repeatedly moved by pulling it out through the outer and inner slide rails until it is stored in the outer box or at least partially exposed in the outer box. The connection method of the slide rails improves the flexibility of repeatedly pulling the pull-out shelf between the outer boxes. Moreover, the pull-out shelf and the outer box are connected by a sliding block, and the rear end of the inner slide rail is located on the rear side of the pull-out shelf, while the front end of the outer slide rail is located on the front side of the outer box. That is, the pull-out shelf can at least move along the outer and inner slide rails with the sliding block until the wiring components inside the pull-out shelf are exposed in the outer box, which facilitates the maintenance of the wiring behind the wiring components by the staff.

[0007] Preferably, the side of the pull-out bracket extends rearward to a rear extension portion, and the rear end of the inner slide rail extends to the rear extension portion.

[0008] By adopting the above technical solution, when the pull-out bracket is moved until the slider slides to the rear extension of the inner slide rail and the slider is located at the front end of the outer slide rail, the pull-out bracket is in its maximum extended state relative to the outer box. At this time, the pull-out bracket is hinged to the outer box only through the rear extension and the slider. Using the pull-out bracket's own gravity, the pull-out bracket can drive the wiring assembly to flip downwards, so that the device on the rear side of the wiring assembly is exposed to a greater extent and displayed in the outer box. This makes it easier for staff to view and maintain the wiring connection on the rear side of the wiring assembly, and increases the operable space for the wiring on the rear side of the wiring assembly.

[0009] Preferably, the side of the outer box body extends forward to have a front extension portion, and the front end of the outer slide rail extends to the front extension portion.

[0010] By adopting the above technical solution, when the pull-out bracket is moved until the slider slides to the front extension of the outer slide rail and the slider is located at the rear end of the inner slide rail, the pull-out bracket flips downward by its own gravity, so that the rear side of the wiring assembly is clearly displayed on the outside of the outer box, which provides convenience for the connection and maintenance of the wiring assembly's rear wiring.

[0011] Preferably, the pull-out bracket is provided with a mounting bracket, and the wiring assembly is detachably connected to the mounting bracket.

[0012] By adopting the above technical solution, the pulling of the drawer can cause vibration in the wiring assembly, affecting its stability. The mounting bracket can provide some fixation for the wiring assembly, making it more stable during the drawer's movement and thus improving its overall stability. When the drawer is pulled out of the outer casing, the wiring assembly, which typically connects to multiple communication cables, allows for detachable installation of both the wiring assembly and the mounting bracket. This enables more convenient maintenance by allowing the entire wiring assembly to be disassembled for further operation.

[0013] Preferably, the wiring assembly has a fixing member on the side facing the pull-out direction of the pull-out bracket, and the fixing member is detachably connected to the mounting bracket.

[0014] By adopting the above technical solution, the wiring assembly and the mounting bracket are detachably connected, giving the wiring assembly more operating space. The wiring assembly may slide down after the pull-out tray is flipped. When the wiring assembly does not need to be disassembled from the mounting bracket for maintenance, the fixing components provided with the wiring assembly ensure that the wiring assembly remains stable with the mounting bracket even when the pull-out tray is flipped. Preferably, the outer housing is provided with a locking mechanism to limit and lock the pull-out tray, and the locking mechanism is installed on the side of the outer housing; the pull-out tray is provided with an insertion part adapted to the locking mechanism.

[0015] Preferably, the outer box is provided with a locking mechanism for limiting and locking the pull-out bracket, and the locking mechanism is installed on the side of the outer box; the pull-out bracket is provided with an insertion part adapted to the locking mechanism.

[0016] By adopting the above technical solution, the wiring device is normally installed inside the outer box along with the pull-out bracket. The outer box and the pull-out bracket are locked and released through a locking mechanism that works in conjunction with the insertion part. When the locking mechanism and the insertion part work together to lock the pull-out bracket inside the outer box, even if the outer box vibrates or tilts, the pull-out bracket will not easily detach from the outer box, thus improving the stability of the connection and installation between the pull-out bracket and the outer box.

[0017] Preferably, the locking mechanism includes a locking rod and a locking seat. The locking seat is installed on the outer side of the outer box and has an insertion hole for the locking rod to pass through. The side of the outer box has a through hole coaxially arranged with the insertion hole, and the locking rod is inserted into the insertion hole and the through hole. The locking rod has a protrusion on its periphery, and the protrusion is located in the insertion hole. One end of the locking seat has a radially inward flange. A spring is provided between the flange and the protrusion to force the protrusion to move toward the through hole. The insertion part is a groove for the inner end of the locking rod to be inserted, and the insertion part is located on the mounting bracket.

[0018] By adopting the above technical solution, the flange design prevents the spring from disengaging within the insertion hole. The spring extends within the insertion hole, pushing the protrusion towards the pull-out bracket in its normal position. Simultaneously, the movement of the protrusion drives the locking rod to move towards the pull-out bracket, ensuring the locking rod is normally engaged with the insertion part of the mounting bracket. When the mounting bracket needs to be pulled out of the outer casing, the locking rod is pulled away from the outer casing, disengaging the locking rod from the insertion part, thus allowing the mounting bracket to be pulled out of the outer casing.

[0019] Preferably, a magnetic block is provided at the upper end of the opening of the outer box; an outer cover is hinged to one side of the front side of the pull-out bracket, and the outer cover has an outer magnetic conductive part that is magnetically connected to the magnetic block.

[0020] By adopting the above technical solution, based on actual usage needs, the frequency of maintenance by pulling out the outer box is low, the opening of the outer box is large, and when the pull-out bracket is placed inside the outer box, the long-term uncovered situation is not conducive to keeping the wiring components clean for a long time. The outer cover is magnetically connected to the magnetic block, which effectively solves the problem of dust easily getting into the uncovered opening of the outer box.

[0021] Preferably, a first cable management plate is provided on the rear side of the pull-out bracket, and the first cable management plate is located on the rear side of the wiring assembly; a second cable management plate is connected to the rear side of the outer box.

[0022] By adopting the above technical solution, the wiring assembly is generally connected to a large number of communication cables. The first cable management plate installed on the back of the pull-out rack can organize the communication cables connected to the back of the wiring assembly. At the same time, a second cable management plate is provided on the back of the outer box. The two cable management plates organize and separate the communication cables, effectively solving the problem of a large number of communication cables being easily messy.

[0023] Preferably, the first cable management plate is hinged to the pull-out bracket.

[0024] By adopting the above technical solution, when the pull-out bracket is flipped, the first cable management board is also pulled out of the outer box. When inspecting and performing minor maintenance, the wiring assembly does not need to be disassembled from the mounting bracket. At this time, the space between the first cable management board and the rear side of the wiring assembly is small, which obstructs the view and makes it inconvenient to inspect and maintain. The first cable management board is hinged to the pull-out bracket, allowing the cable management board to be flipped, thereby improving the operability of the rear side of the wiring assembly.

[0025] Preferably, a detachable reinforcing connecting rod is provided between the outer box and the pull-out frame, and the reinforcing connecting rod is arc-shaped; a connecting block is provided on the front side of the pull-out frame, and a connecting ring is provided on the upper part of the opening of the outer box; both ends of the reinforcing connecting rod are equipped with hooks, one end of the hook is installed on the connecting ring, and the other end is installed on the connecting block.

[0026] By adopting the above technical solution, when the pull-out bracket is pulled out of the outer box, the lack of external support means that operators need to support the pull-out bracket while maintaining the wiring components and communication cables at the rear of the bracket, which is inconvenient for operators. The reinforcing connecting rod connects and securely fixes the pull-out bracket to the outer box, eliminating the need for operators to support the bracket simultaneously, thus improving operator maneuverability and maintenance efficiency. The reinforcing connecting rod is arc-shaped, and this arc structure allows for more space for movement between the reinforcing connecting rod and the wiring components, facilitating operator operation.

[0027] Preferably, the reinforcing connecting rod is a telescopic rod, which includes an outer tube and an inner tube. The inner tube can telescopically move and retract to connect with the outer tube. The inner tube is provided with a positioning element at its inner end, which prevents the inner tube from completely detaching from the outer tube.

[0028] By adopting the above technical solution, the reinforcing connecting rod needs to be hung between the connecting block and the connecting ring. The reinforcing connecting rod needs to be relatively long, and when the pull-out bracket is not needed, it needs to be stored and placed away. For ease of use later, the reinforcing connecting rod is designed as a telescopic rod that can be placed in the outer casing, making it easily accessible and usable. The inner tube, passing through the inner end of the outer tube, has a positioning component that prevents the inner tube from completely detaching from the outer tube. When the reinforcing connecting rod needs to be pulled out, the positioning component securely connects the outer tube and the inner tube, and the two are interlocked for coordinated use.

[0029] Preferably, there are at least two reinforcing connecting rods, and all the reinforcing connecting rods are evenly installed between the outer box and the pull-out bracket.

[0030] By adopting the above technical solution, there are at least two reinforcing connecting rods that are evenly distributed. Even distribution can balance the force, and having at least two rods can further improve the stability and balance of the connection between the outer box and the pull-out frame.

[0031] In summary, this application includes at least one of the following beneficial technical effects: 1. The pull-out bracket can be pulled out and folded to facilitate the inspection and maintenance of the wiring components installed on the pull-out bracket.

[0032] 2. The wiring assembly and the mounting bracket are detachably connected. The wiring assembly can also be fixed to the mounting bracket when the pull-out bracket is folded, so it is not easy to slide down due to tilting.

[0033] 3. The cable management board distributes and arranges the communication cables at the back end of the wiring components, effectively solving the problem of excessive and messy wiring at the back end of the wiring components. Attached Figure Description

Detailed Implementation

[0044] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0045] Example 1 This application discloses a pull-out wiring device.

[0046] Reference Figure 1 and Figure 2 A pull-out wiring device includes an outer box 1 and a pull-out bracket 2; the outer box 1 has a forward-facing opening 13; both the outer box 1 and the pull-out bracket 2 have two sides 12; the pull-out bracket 2 is located between the two sides 12 of the outer box 1.

[0047] refer to Figure 2 and Figure 3 The outer box 1 has an outer slide rail 15 on its side 12, and the pull-out bracket 2 has an inner slide rail 21 on its side 12. A slider 3 connects the pull-out bracket 2 to the outer box 1. One side of the slider 3 is slidably mounted on the inner slide rail 21, and the other side is slidably mounted on the outer slide rail 15. The front end of the outer slide rail 15 extends toward the front of the outer box 1 towards the opening 13. A wiring assembly 5 is installed on the front of the pull-out bracket 2. The rear end of the inner slide rail 21 is located behind the wiring assembly 5. The pull-out bracket 2 can be pulled out by means of the outer slide rail 15 and the inner slide rail 21. The slide rail moves repeatedly until it is stored in the outer box 1 or at least partially exposed in the outer box 1. The movement of the slide rail reduces the friction caused by direct pulling between the pull-out bracket 2 and the outer box 1. The rear end of the inner slide rail 21 is located behind the pull-out bracket 2, and the front end of the outer slide rail 15 is located in front of the outer box 1. That is, the pull-out bracket 2 can at least move with the slider 3 along the outer slide rail 15 and the inner slide rail 21 until the rear side of the wiring assembly 5 inside the pull-out bracket 2 is exposed in the outer box 1, making it more convenient for staff to maintain the wiring behind the wiring assembly 5.

[0048] refer to Figure 3The outer box 1 has a magnetic block 14 at the upper end of the opening 13; the pull-out shelf 2 has an outer cover 4 hinged to one side of its front, and the outer cover 4 has an external magnetic conductive part 41 that is magnetically connected to the magnetic block 14. In this embodiment, the magnetic block 14 is a magnet, and the outer cover 4 is made of ferrous metal. When the pull-out shelf 2 is placed inside the box, the outer cover 4 is magnetically connected to the magnetic block 14, which can partially cover the opening 13 of the outer box 1 to reduce dust accumulation. The outer cover 4 and the pull-out shelf 2 are hinged, giving the outer cover 4 a certain degree of flexibility and allowing it to be flipped. Of course, the outer box 1 and the outer cover 4 can also be detachably connected by means of buckles or screws.

[0049] refer to Figure 3 To achieve the effect of pulling the drawer 2 out of the outer box 1 and flipping it over, the side 12 of the drawer 2 extends backward with a rear extension 22, and the rear end of the inner slide rail 21 extends to the rear extension 22; the side 12 of the outer box 1 can also extend forward with a front extension 16, and the front end of the outer slide rail 15 extends to the front extension 16; of course, both of the above structures can be combined at the same time. When the drawer 2 is moved until the slider 3 slides to the rear extension 22 at the rear end of the inner slide rail 21 or the front extension 16 at the front end of the outer slide rail 15, the drawer 2 can be unfolded to the maximum pull-out state relative to the outer box 1; at this time, the drawer 2 is hinged to the outer box 1 through the extension and the slider 3. Using the weight of the drawer 2 itself, the drawer 2 can drive the wiring assembly 5 to flip, so that the device on the rear side of the wiring assembly 5 is exposed to a greater extent in the outer box 1, which makes it easier for staff to view and maintain the wiring connection on the rear side of the wiring assembly 5, and increases the operable space for the wiring on the rear side of the wiring assembly 5. In this embodiment, the outer box 1 has a front extension 16 extending forward on its side 12 and a rear extension 22 extending backward on its side 12.

[0050] In this embodiment, the outer slide rail 15 is further provided with a reinforcing connecting rail inside the outer box 1. The reinforcing connecting rail is connected to the outer slide rail 15 to increase the load-bearing capacity of the outer slide rail 15. When the pull-out frame 2 is folded, the outer extension needs to bear the overall weight of the pull-out frame 2. The reinforcing connecting rail improves the load-bearing strength of the outer slide rail 15.

[0051] refer to Figure 4 and Figure 5The pull-out drawer 2 is equipped with a mounting bracket 6. The wiring assembly 5 is detachably connected to the mounting bracket 6. The two sides of the mounting bracket 6 are connected to the pull-out drawer 2 and stand upright on it, forming a space for installing the wiring assembly 5. Directly placing the wiring assembly 5 on the pull-out drawer 2 lacks stability; mounting it to the mounting bracket 6 ensures relative stability when the pull-out drawer 2 is pulled out. A fixing member 51 is provided on the side of the wiring assembly 5 facing the pull-out direction of the drawer 2. The fixing member 51 is detachably connected to the mounting bracket 6, allowing for diverse maintenance options for the wiring assembly 5. For minor maintenance, the wiring assembly 5 does not need to be removed from the mounting bracket 6; for major maintenance, the wiring assembly 5 can be removed from the mounting bracket 6, providing a larger operating environment. The detachable connection between the fixing member 51 and the mounting bracket 6 can be achieved by screwing, plugging, or magnetic attraction.

[0052] refer to Figure 4 and Figure 6 In this embodiment, a plug-in connection is used. The fixing member 51 has elastic plates on its outer periphery, with at least two plates evenly arranged around the outer periphery of the fixing member 51. The mounting bracket 6 has mounting holes 61 for the fixing member 51 to be inserted. When the wiring assembly 5 needs to be fixedly installed on the mounting bracket 6, the operator closes the two plates through the mounting holes 61, and then unfolds the plates to insert and connect the wiring assembly 5 to the mounting bracket 6. When the wiring assembly 5 needs to be disassembled, the operator closes the two plates again and pulls the fixing member 51 to remove the wiring assembly 5 from the mounting bracket 6.

[0053] refer to Figure 3 and Figure 5The outer box 1 has a locking mechanism 7 on its side 12, which locks the pull-out bracket 2 inside the outer box 1. The locking mechanism 7 includes a locking rod 71, a locking seat 72, and a spring 73. In this embodiment, both the outer box 1 and the locking rod 71 are made of metal. Long-term insertion and removal of the outer box 1 and the locking rod 71 will cause wear, and the metal material has wear-resistant properties. The locking seat 72 can be fixedly installed on the outside of the outer box 1 by welding or other methods. The locking seat 72 is provided with an insertion hole 74. The side 12 of the outer box 1 is provided with a through hole 11 coaxially arranged with the insertion hole 74. The locking rod 71 passes through the insertion hole 74 and the through hole 11. The locking rod 71 is provided with a protrusion 711 on its periphery, and the protrusion 711 is located in the insertion hole 74. One end of the locking seat 72 is provided with a radially inward flange 721. In this embodiment, the flange 721 is provided at the end of the locking seat 72 away from the outer box 1. A spring 73 is provided between the flange 721 and the protrusion 711 to force the protrusion 711 to move toward the through hole 11. The flange 721 is used to prevent the spring 73 from disengaging from the insertion hole 74. The insertion part 62 is provided on the mounting bracket 6. The insertion part 62 is a groove for the inner end of the locking rod 71 to be inserted. In this embodiment, the groove is a through groove. When the pull-out bracket 2 is stored in the outer box 1, under the action of the spring 73, one end of the locking rod 71 passes through the insertion hole 74 and the through hole 11 in sequence, and is inserted into the insertion part 62, so the position between the pull-out bracket 2 and the outer box 1 is relatively fixed. When the pull-out bracket 2 needs to be pulled out of the outer box 1, the locking rod 71 is pulled away from the outer box 1, so that the spring 73 in the insertion hole 74 is compressed, and the locking rod 71 is separated from the insertion part 62. At this time, the locking mechanism 7 between the mounting bracket 6 and the outer box 1 is in the unlocked state, so that the pull-out bracket 2 can be pulled out of the outer box 1.

[0054] refer to Figure 6 The mounting bracket 6 has an inwardly bent guide plate 18 on the side facing the rear extension 22; the end of the guide plate 18 near the rear extension 22 is normally located inside the locking mechanism 7; the side of the guide plate 18 near the outer box 1 is smoothly connected to the side of the mounting bracket 6 near the outer box 1. When the pull-out bracket 2 needs to be stored in the outer box from the outside, there is no need for personnel to pull the locking rod 71 outward. The guide plate 18 can be used to gradually force the locking rod 71 to move outward and guide it to be inserted into the insertion part 62.

[0055] refer to Figure 7A first cable management plate 9 is provided on the rear side of the pull-out shelf 2, located behind the wiring assembly 5. A second cable management plate 10 is connected to the rear side of the outer box 1. The first cable management plate 9 and the second cable management plate 10 separate and organize the communication cables connected to the rear side of the wiring assembly 5. To facilitate the organization and maintenance of the cables on the rear side of the wiring assembly 5, the cable management plate can be hinged to one side of the rear side of the pull-out shelf 2. Specifically, the hinge has a torsion spring or other connecting component that forces the first cable management plate 9 to be perpendicular to the bottom plate of the pull-out shelf 2 in a normal state. In this way, the first cable management plate 9 is normally in a state where the cables are separated and standing upright on the pull-out shelf 2. When more operations are needed on the rear side of the wiring assembly 5, the first cable management plate 9 can be flipped towards the outer box 1, allowing it to tilt and reducing obstruction of the rear side of the wiring assembly 5, thus improving the operability of the rear side of the wiring assembly 5.

[0056] The implementation principle of a pull-out wiring device according to an embodiment of this application is as follows: An inner slide rail 21 and an outer slide rail 15 are provided between the pull-out bracket 2 and the outer box 1. The inner slide rail 21 or the outer slide rail 15 has an extension. The slider 3 provided between the slide rails slides to the extension and uses the weight of the pull-out bracket 2 to make the pull-out bracket 2 flip. The wiring assembly 5 is installed on the mounting bracket 6 provided on the pull-out bracket 2. A fixing member 51 is provided on the side 12 of the outer box 1. When the pull-out bracket 2 does not need to be pulled out of the outer box 1, the fixing member 51 is inserted and connected to the mounting bracket 6 to fix it inside the outer box 1, thereby improving the stability of the wiring assembly 5 in the pull-out bracket 2.

[0057] Example 2 This application discloses a pull-out wiring device.

[0058] refer to Figure 8 Based on Embodiment 1, the difference between this embodiment and Embodiment 1 is that a detachable reinforcing connecting rod 8 is provided between the outer box 1 and the pull-out bracket 2, as detailed below: The reinforcing connecting rod 8 is a telescopic rod, which includes an outer tube 81 and an inner tube 82. The inner tube 82 can be retracted into the outer tube 81, and a positioning element 821 is provided at the inner end of the inner tube 82 retracted into the outer tube 81.

[0059] refer to Figure 9 In this embodiment, the positioning element 821 is a spring clip. When the outer tube 81 pulls the inner tube 82 to the connecting end of the outer tube 81, the positioning element 821 can be used to limit and fix the inner tube 82 and the outer tube 81, so that the outer tube 81 and the inner tube 82 will not separate. The reinforcing connecting rod 8 can be made of a hard and non-deformable material such as metal, so that it has a large load-bearing capacity and is not easily deformed. In order to match the degree of downward flipping of the pull-out bracket 2 relative to the outer box 1, the reinforcing connecting rod 8 can be equipped with multiple positioning elements 821 at different positions.

[0060] refer to Figure 8The front side of the pull-out bracket 2 is provided with a connecting block 20 that connects to the reinforcing connecting rod 8. The upper part of the opening 13 of the outer box 1 is provided with a connecting ring 17. Both ends of the reinforcing connecting rod 8 are equipped with hooks 83. When it is necessary to fix the pull-out bracket 2, one end of the hook 83 is installed on the connecting ring 17 and the other end is installed on the connecting block 20. In this embodiment, the connecting block 20 is installed on the mounting bracket 6, and the connecting block 20 embeds and fixes the hooks 83 of the reinforcing connecting rod 8. The reinforcing connecting rod 8 is telescopic, so that it can be placed in a small space when not in use. There are two reinforcing connecting rods 8, which are evenly distributed between the outer box 1 and the pull-out bracket 2, so that the outer box 1 and the pull-out bracket 2 are evenly stressed. The reinforcing connecting rod 8 includes an inner tube 82 and an outer tube 81, both of which are arc-shaped.

[0061] The implementation principle of a pull-out wiring device according to an embodiment of this application is as follows: A reinforcing connecting rod 8 is also provided between the pull-out bracket 2 and the outer box 1. The reinforcing connecting rod 8 is an arc-shaped telescopic rod with a hook 83, which can be installed between the connecting block 20 provided on the pull-out bracket 2 and the connecting ring 17 provided on the outer box 1, so that the pull-out bracket 2 can be fixed at a certain angle after being flipped, realizing the function of fixing it after being pulled out for easy maintenance. In addition, the pull-out bracket 2 is equipped with a mounting bracket 6, and the mounting bracket 6 is equipped with a wiring assembly 5. The mounting bracket 6 and the fixing part 51 of the wiring assembly 5 are detachably connected, which makes the maintenance of the wiring assembly 5 more possible and provides more convenience for maintenance.

[0062] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
