Description

Technical Field

[0001] This utility model relates to the field of patch panel technology, and in particular to a high-density modular fiber optic patch panel. Background Technology

[0002] With the advent of the Internet of Everything era and the rapid development of AI technology, the application scenarios of fiber optic communication products have increased dramatically.

[0003] However, traditional fiber optic patch panels typically employ a fixed modular installation structure, which still presents many technical challenges. For example, insufficient density: traditional patch panels usually only support 72 cores or lower within a 1U space, resulting in low rack space utilization and increased costs.

[0004] Poor scalability: The fixed design cannot flexibly adapt to module boxes with different core counts, and upgrades and maintenance require complete equipment replacement. Difficult cable management: Insufficient storage space at the rear makes it difficult to organize leftover patch cords, easily leading to cable tangling or damage.

[0005] Weak dust resistance: Open cable entry points lead to dust accumulation, affecting fiber optic transmission performance. Complex installation: Multiple people are required to complete equipment mounting and module disassembly / removal, resulting in high labor costs. Furthermore, traditional fiber optic patch panel module boxes only support single-sided installation, typically inserted from the front, and cannot be operated bidirectionally; the module boxes are fixed in the tray using screws or clips, requiring tools for disassembly and reassembly; cable management relies on external cable management rings, with no redundant storage space at the rear; the tray is a single-piece design that cannot be independently slidable or disassembled, indicating room for improvement in the existing technology. Summary of the Invention

[0006] This utility model addresses the aforementioned existing situation by providing a high-density modular fiber optic distribution frame, comprising a housing and at least one mounting bracket movably disposed within the housing. The mounting bracket is provided with a plurality of mounting positions for mounting module boxes. Each mounting position has an inner guide rail for mounting module boxes on both sides. Each inner guide rail has a guide groove on both sides. Each module box has a first guide plate and a second guide plate fixedly disposed on both sides for engaging with the guide grooves on adjacent inner guide rails.

[0007] Preferably, the inner guide rail has a notch that connects the guide grooves on both sides of the inner guide rail. A first positioning block for engaging with the notch and positioning the module box is fixedly installed on the second guide plate. A first pressure plate for disengaging the first positioning block from the notch after being pressed and bent is provided on the second guide plate. A second positioning block is fixedly installed in the guide groove on the inner guide rail facing the second guide plate and limiting the second guide plate. A second pressure plate that can be bent after being pressed is fixedly installed at the end of the inner guide rail away from the first pressure plate. The second positioning block is installed on the second pressure plate and can move to the outside of the movement path of the second guide plate after the second pressure plate bends.

[0008] Preferably, the first positioning block is provided with a guide slope that causes the first positioning block to disengage from the notch when the module box moves toward the second pressure plate. The guide slope gradually slopes from the second guide plate toward the first guide plate toward the second positioning block.

[0009] Preferably, the mounting frame includes three trays evenly distributed along the height of the housing. The two sides of the trays are movably mounted in the frame via outer guide rails and can move along the length of the outer guide rails. The inner guide rails are fixedly mounted on the trays, and the trays and two adjacent inner guide rails form the mounting positions for mounting the module boxes.

[0010] Preferably, each end of the tray is fixedly provided with a sliding plate that is engaged with the outer guide rail and can move along the length of the outer guide rail. The sliding plate has two stop grooves, and the outer guide rail has two stop blocks that cooperate with the stop grooves.

[0011] Preferably, a support plate for supporting the entire housing is fixedly disposed inside the housing.

[0012] Preferably, the housing is fitted with a front door and a rear cover at both ends, with a cable storage area for redundant optical cables coiled below the rear cover. The front door is mounted on the frame via a hinge, and the rear cover is snapped onto the housing and secured with a nut.

[0013] Preferably, the tray is fixedly provided with a number of built-in cable management rings for managing fiber optic patch cords at one end facing the front door.

[0014] Preferably, the cable storage area is provided with a mounting plate, which is provided with a plurality of cable bundlers for fixing the cables.

[0015] Preferably, the cable storage area has openings on both sides that connect to the outside of the housing for cable threading. A long brush is installed inside the opening, and a cable protection sleeve is fixedly installed on the inner wall of the opening.

[0016] Preferably, the front door is provided with a recording card for recording update and maintenance status.

[0017] Preferably, the housing is fixedly provided with mounting ears on both sides for mounting the housing in the cabinet.

[0018] Compared with the prior art, this utility model installs the module box by means of inner guide rails on both sides of the mounting position. The first notch and the first positioning block cooperate to limit the module box in the rear direction, and the second positioning block and the second guide plate cooperate to limit the module box in the front direction. This allows for easy front or rear insertion of the module box. Through modular design, two module boxes on both sides are installed and fixed by the same inner guide rail, which effectively reduces the installation space, increases the fiber optic installation density, and significantly increases the overall installation capacity of the equipment.

[0029] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings: Example

[0030] like Figure 1-7 As shown, a high-density modular fiber optic patch panel includes a housing 1 and a mounting bracket 2 movably disposed within the housing 1. The housing 1 has mounting ears 30 fixedly disposed on both sides for mounting the housing 1 in a cabinet. During cabinet installation, the patch panel is horizontally pushed into a 19-inch cabinet and fixed by M6×10 mm mounting ear 30 screws.

[0031] The mounting bracket 2 is provided with several mounting positions 3 for mounting module boxes 31. Inner guide rails 4 for mounting module boxes 31 are respectively provided on both sides of each mounting position 3. Guide grooves 5 are respectively provided on both sides of each inner guide rail 4. A first guide plate 6 and a second guide plate 7 are respectively fixedly provided on both sides of each module box 31 for engaging with the guide grooves 5 on adjacent inner guide rails 4. A notch 8 is provided on each inner guide rail 4 connecting the guide grooves 5 on both sides. A first positioning block 9 is fixedly provided on the second guide plate 7 for engaging with the notch 8 to position the module box 31. A first pressure plate 10 is provided on the guide plate 7 for disengaging the first positioning block 9 from the notch 8 after being pressed and bent. A second positioning block 11 is fixedly provided in the guide groove 5 on the inner guide rail 4 facing the second guide plate 7 and limiting the second guide plate 7. A second pressure plate 12 that can be bent after being pressed is fixedly provided at the end of the inner guide rail 4 away from the first pressure plate 10. The second positioning block 11 is provided on the second pressure plate 12 and can move to the outside of the movement path of the second guide plate 7 after the second pressure plate 12 bends. The first guide block has a guide slope 13 that disengages the first positioning block 9 from the notch 8 when the module box 31 moves towards the second pressure plate 12. The guide slope 13 gradually slopes from the second guide plate 7 towards the first guide plate 6 towards the second positioning block 11. The module box 31 is installed via the inner guide rails 4 on both sides of the mounting position 3. The module box 31 is limited in the rear direction by the cooperating first notch 8 and the first positioning block 9. The module box 31 is limited in the front direction by the cooperating second positioning block 11 and the second guide plate 7. The module box 31 can be removed from the rear of the inner guide rail 4 by pressing the first pressure plate 10 to disengage the first positioning block 9 from the first notch 8. The module box 31 can be removed from the front of the inner guide rail 4 by pressing the second pressure plate 12 to move the second positioning block 11 to the outside of the movement path of the second guide plate 7. This allows for convenient front or rear insertion of the module box 31 and significantly reduces the module box 31 replacement time when operated by a single person.

[0032] The mounting frame 2 includes three trays 14 evenly distributed along the height direction of the housing 1. The two sides of the trays 14 are movably mounted in the frame via outer guide rails 15 and can move along the length direction of the outer guide rails 15. The inner guide rails 4 are fixedly mounted on the trays 14. The trays 14 and two adjacent inner guide rails 4 form the mounting positions 3 for mounting the module box 31. The tray 14 has sliding plates 16 fixedly installed at both ends, which are engaged with the outer guide rail 15 and can move along the length of the outer guide rail 15. The sliding plates 16 have two stop grooves 17, and the outer guide rail 15 has two stop blocks 18 that cooperate with the stop grooves 17. When the two stop blocks 18 are engaged with the two stop grooves 17 respectively, the tray 14 is in the storage state. During maintenance, the tray 14 is pulled out towards the front door 20, and the stop blocks 18 are disengaged from the stop grooves 17 until the stop blocks 18 are re-engaged into the stop grooves 17. At this time, only one stop groove 17 of the sliding plate 16 is engaged with the stop block 18, which prevents the tray 14 from moving too far and disengaging from the outer guide rail 15 when it is pulled out, thus effectively ensuring the safety of the tray 14 when it is pulled out. When installing module box 31, insert the first guide plate 6 and the second guide plate 7 on both sides of module box 31 into the guide grooves 5 on the inner guide rails 4 on both sides. When the first positioning block 9 engages with the notch 8, the installation of module box 31 is completed. Through modular design, two module boxes 31 on both sides are installed and fixed by the same inner guide rail 4, effectively reducing installation space, increasing fiber optic installation density, and significantly increasing the overall installation capacity of the equipment. The tray 14 is provided with six installation positions 3. Taking a 1U high-density patch panel and an 8-core LC-MPO module box 31 as an example, 18 module boxes 31 can be inserted at the same time, so that the total capacity reaches 144 cores, effectively improving the installation density of module boxes 31. Furthermore, by adjusting the position of the inner guide rail 4, 8-core, 12-core, 16-core, and 24-core LC-MPO module boxes 31 and MPO-MPO module boxes 31 can be interchanged.

[0033] A support plate 19 is fixedly installed inside the housing 1 to support the entire housing 1. A front door 20 and a rear cover 21 are respectively fastened to both ends of the housing 1, suitable for installation and maintenance in different working scenarios. Below the rear cover 21 is a cable storage area 22 for winding redundant optical cables. The front door 20 is hinged and mounted on the frame. The rear cover 21 is snapped onto the housing 1 and fixed with nuts. After the tray 14 is stored, a certain gap remains between the front end of the module box 31 and the front door 20. Several built-in cable management rings 23 for managing fiber optic patch cords are fixedly installed on one end of the tray 14 facing the front door 20. A mounting plate 24 is installed inside the cable storage area 22, and several cable bundlers 25 for fixing cables are installed on the mounting plate 24. Openings 26 on both sides of the cable storage area 22 connect to the outside of the housing 1 for cable threading. Long brushes 27 are installed inside the openings 26, and cable protection sleeves 28 are fixedly installed on the inner wall of the openings 26. The optical fiber enters through opening 26, is coiled, and then secured to the cable tie 25 with cable ties, connecting to the rear of the module box 31. A long-bristled brush 27 located at opening 26 effectively prevents dust from entering, and a cable sleeve 28 effectively prevents the cable from being scratched during extraction. A gap between the front of the module box 31 and the front door 20, along with a cable storage area 22, allows for cable placement and supports redundant cable coiling, facilitating front or rear insertion into the module box 31.

[0034] The front door 20 is equipped with a recording card 29 for recording update and maintenance status. This allows for convenient recording of update and maintenance status after the front door 20 is opened.

[0035] Example 2

[0036] like Figure 8 As shown, the difference from Embodiment 1 is that there are two mounting brackets 2 inside the housing 1, which are evenly distributed along the height direction of the housing 1 to form a 2U specification, supporting up to 288 cores.

[0037] Example 3

[0038] like Figure 9 As shown, the difference from Embodiment 1 is that the housing 1 has four mounting brackets 2 which are evenly distributed along the height of the housing 1 to form a 4U specification, supporting up to 576 cores.

[0039] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications to the specification derived therefrom are still within the protection scope of this utility model.
