Description

Technical Field

[0001] This invention relates to the field of structured cabling technology, and in particular to a patch panel that enables the interchangeability of fiber optic boxes and data modules. Background Technology

[0002] Patch panels are devices used to connect and manage end-user lines or trunk lines. They are the most important component in the management subsystem, serving as the hub for cross-connecting the vertical backbone and horizontal cabling subsystems. Patch panels are typically mounted in cabinets or on walls. With accessories, patch panels can fully meet the needs of UTP, STP, coaxial cable, fiber optic, and audio / video cabling. Commonly used patch panels in network engineering include twisted-pair patch panels and fiber optic patch panels.

[0003] The fact that all the connectors on a patch panel are the same size means that a patch panel can only be used as a twisted-pair patch panel or a fiber optic patch panel. It is impossible for the same patch panel to function as both a twisted-pair patch panel and a fiber optic patch panel, resulting in poor compatibility. Furthermore, once twisted-pair and fiber optic patch panels are installed in a cabinet or on a wall, they need to be completely removed from the cabinet or wall before the fiber optic box or data module can be replaced or repaired, making subsequent maintenance and replacement inconvenient. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, this invention proposes a patch panel that enables the interchangeability of fiber optic boxes and data modules, thereby improving the compatibility of the patch panel and facilitating future replacement and maintenance.

[0005] This invention is achieved through the following technical solution: a patch panel capable of interchangeable fiber optic boxes and data modules, comprising a frame, a first fixing base, a second fixing base, a fiber optic box, and a data module. The frame is provided with a plurality of plug-in interfaces in sequence along its length. The first fixing base can be detachably mounted on the plug-in interfaces from the front end of the frame. The fiber optic box is mounted on the first fixing base. The second fixing base can be detachably mounted on the plug-in interfaces from the front end of the frame. The data module is mounted on the second fixing base. The plug-in interfaces are equipped with the first fixing base and / or the second fixing base.

[0006] As a further improved technical solution, the first fixing seat includes a first cover plate, a first seat body, and a first mounting hole. The first cover plate and the first seat body are integrally disposed front and rear. The first mounting hole passes through the front and rear ends of the first cover plate and the first seat body. The first fixing seat can be inserted into the plug interface from front to back. When the first fixing seat is assembled into the plug interface, the first cover plate is placed on the front end of the frame and covers the plug interface. The first seat body passes through the plug interface. The optical fiber box is assembled into the first mounting hole. The second fixing seat includes a second cover plate, a second seat body, and a second mounting hole. The second cover plate and the second seat body are integrally formed front and rear. The second mounting hole passes through the front and rear ends of the second cover plate and the second seat body. The second fixing seat can be inserted into the plug-in interface from front to back. When the second fixing seat is assembled into the plug-in interface, the second cover plate covers the front end of the frame and covers the plug-in interface, the second seat body passes through the plug-in interface, and the data module is assembled into the second mounting hole.

[0007] As a further improved technical solution, the first base is provided with a first elastic buckle and a first locking block. The first elastic buckle and the first locking block are respectively located at the upper and lower ends of the first base. The upper end of the first elastic buckle away from the first locking block is provided with a second locking block. The first elastic buckle and the second locking block can approach or move away from the first locking block. When the first elastic buckle is pressed close to the first locking block, the first base can be inserted into the insertion interface. After the first base is inserted into the insertion interface, the first elastic buckle is released, and the first elastic buckle moves away from the first locking block, so that the first elastic buckle abuts against the end wall of the insertion interface. The first locking block and the second locking block abut against the rear end of the frame.

[0008] As a further improved technical solution, the first cover plate is provided with a first through hole, and the first elastic buckle portion passes through the first through hole and is located in front of the first cover plate.

[0009] As a further improved technical solution, the fiber optic box includes a box body and a pair of elastic members disposed on opposite sides of the box body. The pair of elastic members can move closer to each other or further away from each other. When the pair of elastic members move closer to each other, the fiber optic box can be inserted into the first mounting hole from the front end of the first fixing seat. After the fiber optic box is inserted into the first mounting hole, the pair of elastic members are released and move away from each other. The pair of elastic members abut against the opposite sidewalls of the first mounting hole.

[0010] As a further improved technical solution, a sliding groove is provided on each of the two side walls of the first assembly hole, and when the optical fiber box is inserted into the first assembly hole, the elastic element can slide in the sliding groove.

[0011] As a further improved technical solution, guide grooves are provided on both sides of the first assembly hole. The guide grooves are located at the rear end of the slide groove and are connected to it. The slide groove is located outside the guide groove. A limiting step is formed between the slide groove and the guide groove. Guide blocks are also provided on opposite sides of the box body. The guide blocks are adapted to the guide groove. When the optical fiber box is inserted into the assembly hole, the guide blocks slide along the guide groove. The limiting step is located on the sliding trajectory of the elastic element.

[0012] As a further improved technical solution, the bottom wall of the slide is provided with a locking groove recessed in a direction opposite to the axis of the first assembly hole. The elastic element is provided with a locking block at one end opposite to the box body. The locking block is adapted to the locking groove. When the optical fiber box is inserted into the first assembly hole and a pair of elastic elements are released, the locking block is locked into the locking groove to prevent the optical fiber box from moving forward away from the first assembly hole.

[0013] As a further improved technical solution, the second base is provided with a second elastic buckle and a third locking block. The second elastic buckle and the third locking block are respectively located at the upper and lower ends of the second base. A fourth locking block is provided at the end of the second elastic buckle away from the third locking block. The second elastic buckle and the fourth locking block can approach or move away from the first locking block. When the second elastic buckle is pressed close to the third locking block, the second base can be inserted into the insertion interface. After the second base is inserted into the insertion interface, the second elastic buckle is released, and the second elastic buckle moves away from the third locking block, so that the second elastic buckle abuts against the end wall of the insertion interface. The third locking block and the fourth locking block abut against the rear end of the frame.

[0014] As a further improved technical solution, the data module is inserted into the second assembly hole from back to front.

[0015] Compared with the prior art, the present invention, through the arrangement of the first and second fixing bases, allows both fiber optic boxes and data modules to be installed on the same patch panel. This means it can be used as both a twisted-pair patch panel and a fiber optic patch panel, or simultaneously as both, greatly improving the patch panel's compatibility. Furthermore, both the first and second fixing bases can be inserted into the plug-in interface from front to back, or detached from the plug-in interface from front to back, allowing for maintenance and replacement of fiber optic boxes, data modules, etc., without disassembling the patch panel, thus facilitating subsequent use.

[0034] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1 to 18 As shown, a patch panel 100 capable of interchangeable fiber optic box 40 and data module 50 includes a frame 10, a first fixing base 20, a second fixing base 30, a fiber optic box 40, and a data module 50. The frame 10 is provided with a plurality of plug-in interfaces 11 along its length. The first fixing base 20 can be detachably mounted on the plug-in interface 11 from the front end of the frame 10. The fiber optic box 40 is mounted on the first fixing base 20. The second fixing base 30 can be detachably mounted on the plug-in interface 11 from the front end of the frame 10. The data module 50 is mounted on the second fixing base 30. The plug-in interface 11 is equipped with the first fixing base 20 and / or the second fixing base 30.

[0037] Please refer to Figures 1-3 As shown, when all the connectors 11 are assembled with the first mounting bracket 20, the patch panel 100 can be used as a fiber optic patch panel. Please refer to [reference needed]. Figures 10-12 As shown, when all the plug interfaces 11 are equipped with the second fixing base 30, the patch panel 100 can be used as a twisted-pair patch panel. When some plug interfaces 11 are equipped with the first fixing base 20 and the other plug interfaces 11 are equipped with the second fixing base 30, the patch panel 100 can be used as both a fiber optic patch panel and a twisted-pair patch panel, greatly improving the compatibility of the patch panel 100. At the same time, regardless of whether it is the first fixing base 20 or the second fixing base 30, the plug interface 11 can be inserted from the front end of the frame 10 and the plug interface 11 can be pulled out from the front end of the frame 10. The fiber optic box 40 and the data module 50 can be removed for replacement and maintenance without removing the frame 10 from the cabinet or wall, which facilitates subsequent use.

[0038] Please refer to Figures 1-9 As shown, the first fixing base 20 includes a first cover plate 21, a first base body 22, and a first mounting hole 23. The size of the first cover plate 21 is larger than that of the plug interface 11. The first cover plate 21 and the first base body 22 are integrally set front and back. The first mounting hole 23 passes through the front and back ends of the first cover plate 21 and the first base body 22. The first fixing base 20 can be inserted into the plug interface 11 from front to back. When the first fixing base 20 is mounted on the plug interface 11, the first cover plate 21 covers the front end of the frame 10 and covers the plug interface 11. The first base body 22 passes through the plug interface 11. The fiber optic box 40 is mounted in the first mounting hole 23.

[0039] In this embodiment, the first seat 22 is provided with a first elastic buckle 221 and a first locking block 222. The first elastic buckle 221 and the first locking block 222 are respectively located at the upper and lower ends of the first seat 22. A second locking block 223 is provided at the upper end of the first elastic buckle 221 away from the first locking block 222. The first elastic buckle 221 and the second locking block 223 can move closer to or away from the first locking block 222. When the first elastic buckle 221 is pressed closer to the first locking block 222, the second locking block 223 also moves closer to the first locking block 222, and the first seat 22 can be inserted into the insertion interface 11. After the first seat 22 is inserted into the insertion interface 11, the first elastic buckle 221 is released, and the first elastic buckle 221 and the second locking block 223 move closer to each other. Both 23 are far away from the first locking block 222, so that the first elastic buckle 221 abuts against the end wall of the insertion interface 11. The first locking block 222 and the second locking block 223 abut against the rear end of the frame 10. When it is necessary to disassemble the first fixing seat 20, press the first elastic buckle 221 close to the first locking block 222. The second locking block 223 also moves downward with the movement of the first elastic buckle 221, so that the second locking block 223 does not abut against the rear end of the frame 10. Move the first fixing seat 20 upward slightly so that the first locking block 222 does not abut against the rear end of the frame 10. At this time, simply pull the first fixing seat 20 forward to pull the first fixing seat 20 forward out of the insertion interface 11 to disassemble the first fixing seat 20. The first elastic buckle 221, the first locking block 222, and the second locking block 223 facilitate the assembly and disassembly of the first fixing seat 20 and the plug interface 11. Furthermore, the first cover plate 21, the first locking block 222, and the second locking block 223 improve the stability of the first fixing seat 20 when assembled on the plug interface 11, preventing the first fixing seat 20 from shaking and thus ensuring the stability of the fiber optic box 30 after installation.

[0040] The first cover plate 21 is provided with a first through hole 211, and the first elastic buckle 221 passes through the first through hole 211 and is located in front of the first cover plate 21. This arrangement makes it convenient to press the first elastic buckle 221.

[0041] The front end of the frame 10 is also provided with a guide groove 12. The bottom wall of the guide groove 12 extends obliquely upward from front to back. The rear end of the guide groove 12 is connected to the insertion interface 11. The first locking block 222 is adapted to the guide groove 12. When the first fixing seat 20 is inserted into the insertion interface 11, the first locking block 222 can slide along the bottom wall of the guide groove 12, which facilitates the installation of the first fixing seat 20.

[0042] The fiber optic box 40 includes a box body 41 and a pair of elastic members 42 and a pair of guide blocks 43 disposed on opposite sides of the box body 41. The guide blocks 43 and the elastic members 42 are located on the same side of the box body 41 in a one-to-one correspondence. In this embodiment, the guide blocks 43 and the elastic members 42 are integrally connected and formed. The pair of elastic members 42 can move closer to each other or further away from each other. When the pair of elastic members 42 move closer to each other, the fiber optic box 40 can be inserted into the first mounting hole 23 from the front end of the first fixing seat 20. After the fiber optic box 40 is inserted into the first mounting hole 23, the pair of elastic members 42 are released and move further away from each other. The pair of elastic members 42 abut against the opposite sidewalls of the first mounting hole 23.

[0043] The first assembly hole 23 has a pair of sidewalls with a sliding groove 231 and a guide groove 232. The guide groove 232 is located at the rear end of the sliding groove 231 and the two are connected. The sliding groove 231 is located outside the guide groove 232, forming a limiting step 233 between the sliding groove 231 and the guide groove 232. The guide block 43 is adapted to the guide groove 232, and the elastic element 42 is adapted to the sliding groove 231. The bottom wall 235 of the sliding groove 231 is also provided with a locking groove 234 recessed away from the axial direction of the first assembly hole 23. The locking groove 234, the sliding groove 231, and the guide groove 232 are connected in sequence. The end of the elastic element 42 away from the box body 41 is provided with a locking block 44, which is adapted to the locking groove 234. When the fiber optic box 40 is inserted into the first assembly hole 23, the elastic element 42 slides along the sliding groove 231, and the guide block 43 slides along the guide groove. 232 slides, and the limiting step 233 is located on the sliding trajectory of the elastic member 42. When the elastic member 42 abuts against the limiting step 233, the elastic member 42 is released, and the pair of elastic members 42 move away from each other. The locking block 44 is inserted into the locking groove 234, and the elastic member 42 abuts against the bottom wall 235 of the sliding groove. The end of the elastic member 42 away from the guide block 43 is located in front of the first fixed seat 20. The fiber optic box 40 is assembled with the first assembly hole 23. The cooperation between the locking block 44 and the locking groove 234 can effectively prevent the fiber optic box 40 from moving forward out of the first assembly hole 23. When it is necessary to disassemble the fiber optic box 40, simply press the pair of elastic members 42 to bring them closer together, so that the locking block 44 is disassembled from the locking groove 234, and the fiber optic box 40 can be pulled forward to pull the fiber optic box 40 out of the first assembly hole 23, thereby realizing the disassembly of the fiber optic box 40 from the plug interface 11.

[0044] In this embodiment, the height of the guide block 43 near the end of the elastic member 42 gradually increases, and the height of the guide groove 232 near the end of the slide groove 231 also gradually increases. This arrangement can further limit the sliding of the box 41.

[0045] The first mounting base 20 may be provided with multiple first mounting holes 23, which are arranged vertically in sequence. This arrangement allows the same first mounting base 20 to accommodate multiple fiber optic boxes 40, thereby increasing the number of optical fibers that the patch panel 100 can accommodate.

[0046] In this embodiment, the front end of the fiber optic box 40 is provided with multiple fiber optic adapters 60, and the rear end of the fiber optic box 40 is provided with a flange 70. The optical cable enters the fiber optic box 40 from the flange 70 and is distributed to the fiber optic adapters 60. The specific usage and assembly methods of the fiber optic box 40, flange 70 and fiber optic adapters 60 are the same as those in the prior art, and will not be described in detail here.

[0047] Please refer to Figures 10-18 As shown, the second fixing base 30 includes a second cover plate 31, a second base body 32, and a second mounting hole 33. The size of the second cover plate 31 is larger than that of the plug-in interface 11. The second cover plate 31 and the second base body 32 are integrally set front and rear. The second mounting hole 33 passes through the front and rear ends of the second cover plate 31 and the second base body 32. The second fixing base 30 can be inserted into the plug-in interface 11 from front to back. When the second fixing base 30 is mounted on the plug-in interface 11, the second cover plate 31 covers the front end of the frame 10 and covers the plug-in interface 11. The second base body 32 passes through the plug-in interface 11. The data module 50 is mounted in the second mounting hole 33.

[0048] In this embodiment, the second seat 32 is provided with a second elastic buckle 321 and a third locking block 322. The second elastic buckle 321 and the third locking block 322 are located at the upper and lower ends of the second seat 32, respectively. The third locking block 322 is also adapted to the guide groove 12. A fourth locking block 323 is provided at the end of the second elastic buckle 321 away from the third locking block 322. The second elastic buckle 321 and the fourth locking block 323 can move closer to or further away from the third locking block 322. When the second elastic buckle 321 is pressed closer to the third locking block 322, the fourth locking block 323 also moves closer to the third locking block 322. The third locking block 322 moves along the bottom wall of the guide groove 12 from front to back, so that the second fixed seat 20 moves from front to back and upward until the second seat 32 is inserted into the insertion interface 11. The second cover plate 31 abuts against the front end of the frame 10 and covers the insertion interface 11. Then the second elastic buckle 321 is released. 1. The second elastic buckle 321 moves away from the third buckle 322, and the fourth buckle 323 also moves away from the third buckle 322, so that the second elastic buckle 321 abuts against the end wall of the insertion interface 11, and the third buckle 322 and the fourth buckle 323 abut against the rear end of the frame 10, so that the second fixing seat 30 is fixedly connected to the insertion interface 11. When it is necessary to disassemble the second fixing seat 30, press the second elastic buckle 321 closer to the third buckle 322, and the fourth buckle 323 also moves downward with the second elastic buckle 321 and closer to the third buckle 322, so that the fourth buckle 323 does not abut against the rear end of the frame 10. Move the second fixing seat 30 upward slightly so that the third buckle 322 does not abut against the rear end of the frame 10. At this time, simply pull the second fixing seat 30 forward to pull the second fixing seat 30 forward out of the insertion interface 11 to disassemble the second fixing seat 30. The second elastic buckle 321, the third latch 322, and the fourth latch 323 facilitate the assembly and disassembly of the second fixing base 30 and the plug interface 11. Furthermore, the second cover plate 31, the third latch 322, and the fourth latch 323 improve the stability of the second fixing base 30 mounted on the plug interface 11, preventing the second fixing base 30 from shaking and thus ensuring the stability of the data module 50 after installation.

[0049] In this embodiment, a label groove 311 is provided on the second cover plate 31, and a transparent cover 34 is rotatably provided on the label groove 311. The transparent cover 34 can be rotatably placed on the label groove 311. A second through hole 312 is provided in the label groove 311, and a second elastic buckle 321 is inserted forward into the second through hole 312 to facilitate pressing the second elastic buckle 321.

[0050] In this embodiment, the data module 50 is inserted into the second assembly hole 33 from back to front. Specifically, the data module 50 is provided with an elastic hook 51 and a fifth locking block 52 at its upper and lower ends, respectively. The second assembly hole 33 is provided with a first locking groove and a second locking groove 331, which are arranged vertically opposite each other. The elastic hook 51 is adapted to the first locking groove, and the fifth locking block 52 is adapted to the second locking groove 331. The data module 50 is detachably assembled with the second assembly hole 33 through the cooperation of the elastic hook 51 with the first locking groove and the cooperation of the fifth locking block 52 with the second locking groove 331.

[0051] The second assembly holes 33 on the same second fixed seat 30 are at least a group, and each group of second assembly holes 33 is distributed sequentially along the length of the frame 10. When there are multiple groups of second assembly holes 33, the multiple groups of second assembly holes 33 are distributed vertically.

[0052] When the frame 10 is made of metal, a metal shield 80 is also provided between the data module 50 and the frame 10 to improve the shielding performance of the patch panel 100 and improve the signal transmission stability of the data module 50.

[0053] The metal shielding component 80 includes a single body 81. The upper end of the body 81 is provided with several first fixing plates 82, and the lower end of the body 81 is provided with contact plates 83. Each of the first fixing plates 82 corresponds to a second mounting hole 33, and the first fixing plate 82 is inserted into the second mounting hole 33 to abut against the data module 50. The contact plate 83 abuts against the frame 10. Specifically, the body 81 covers the rear end of the second base 32. The first fixing plates 82 are provided with first latches 821, and the bottom wall of the second mounting hole 33 is provided with… There is a first protrusion 332, which is adapted to the first bayonet 821.
