Description

Technical Field

[0001] This utility model relates to the field of optical communication, and in particular to a pull-out fiber optic distribution frame. Background Technology

[0002] Optical distribution frames (ODFs) are core devices in optical communication networks, used for fiber splicing, storage, distribution, and scheduling, similar to a "distribution box" in an electrical circuit. They play a crucial role in data centers, server rooms, base stations, and other scenarios, directly impacting network reliability, maintainability, and scalability. Against the backdrop of rapid global digital transformation and smart infrastructure development, fiber optic networks, as the "nerve cuffs" of the digital society, face stringent requirements for high-density deployment, ultra-low-loss transmission, and adaptation to complex environments. Existing ODFs are generally stacked in multiple units, so a pull-out design is typically used for easy installation and maintenance. However, existing pull-out ODFs require bending the fiber optic cable to a certain radius before it can be inserted into the ODF and the fiber optic cable can be led out through the terminals. If the bending radius exceeds 30 millimeters, the fiber optic cable will suffer physical damage. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a pull-out fiber optic patch panel, which is easy to pull out and does not require bending of cables during installation.

[0004] Therefore, one embodiment provides a pull-out fiber optic patch panel, comprising:

[0005] The guide rail includes a first guide rail and a second guide rail, wherein the first guide rail and the second guide rail are arranged in parallel.

[0006] The first slide rail is slidably connected to the first guide rail and can move along the length of the first guide rail;

[0007] The second slide rail is slidably connected to the second guide rail and can move along the length of the second slide rail;

[0008] A wiring panel is fixedly connected to the first slide rail and the second slide rail. The wiring panel includes terminals for threading optical fibers.

[0009] The winding mechanism includes a front bracket and a rear bracket for winding cables. One end of the rear bracket is hinged to the guide rail, and the other end of the rear bracket is hinged to one end of the front bracket. The other end of the front bracket is hinged to the wiring panel or the second slide rail.

[0010] As a further alternative to the pull-out fiber optic patch panel, the winding mechanism also includes mounting components, two of which are respectively fixedly connected to the front bracket and the rear bracket to secure the cable.

[0011] As a further alternative to the pull-out fiber optic patch panel, the mounting component includes a first surface and a second surface, wherein the first surface is connected to the second surface and the front bracket or the rear bracket, respectively.

[0012] As a further alternative to the pull-out fiber optic patch panel, the top view projection of the second surface lies within the top view projection of the first surface.

[0013] As a further alternative to the pull-out fiber optic patch panel, the patch panel also includes a brush, which is disposed below the terminal block.

[0014] As a further alternative to the pull-out fiber optic patch panel, the patch panel also includes a drive mechanism, which is used to move the patch panel.

[0015] As a further alternative to the pull-out fiber optic patch panel, the guide rail is provided with an abutment portion, which is used to abut against the patch panel to prevent the patch panel from extending into the space between the guide rails.

[0016] As a further optional solution for the pull-out fiber optic patch panel, when the patch panel abuts against the abutting part, the bending radius of the cable between the front bracket and the rear bracket is not less than 35mm.

[0017] As a further alternative to the pull-out fiber optic patch panel, the terminals are arranged in an array both horizontally and vertically.

[0018] As a further alternative to the pull-out fiber optic patch panel, a connector is also included for connecting the patch panel and the guide rail.

[0019] Implementing the embodiments of this utility model will have the following beneficial effects:

[0020] According to the pull-out fiber optic patch panel in the above embodiment, the installer first pulls out the patch panel, which is connected to the first and second slide rails. The first slide rail is slidably connected to the first guide rail, and the second slide rail is connected to the second guide rail, thus allowing the patch panel to be pulled out. At this time, the front and rear brackets are straightened, and the installer places the cable on the front and rear brackets, leading out the optical fiber from the cable and passing it through the terminal block. Then, the installer pushes the patch panel back. During the process of pushing the patch panel back, since one end of the rear bracket is hinged to the guide rail and the other end is hinged to one end of the front bracket, and the other end of the front bracket is hinged to the patch panel or the second slide rail, the front and rear brackets will bend relative to each other, and the cable placed on the front and rear brackets will also bend. Since the bending angle of the front and rear brackets is fixed, the bending arc of the cable after bending is also fixed, which can avoid large errors caused by human operation that could result in physical damage to the cable. The pull-out fiber optic patch panel in the embodiment can realize a fiber optic patch panel that is easy to pull out and does not require bending of cables during installation.

[0030] This utility model embodiment provides a pull-out fiber optic patch panel, please refer to... Figure 1 and Figure 2 The system includes a guide rail 10, a first slide rail 20, a second slide rail 30, a wiring panel 40, and a winding mechanism 50. The guide rail 10 includes a first guide rail 110 and a second guide rail 120, which are arranged parallel to each other. The first slide rail 20 is slidably connected to the first guide rail 110 and can move along the length of the first guide rail 110. The second slide rail 30 is slidably connected to the second guide rail 120 and can move along the length of the second slide rail 30. The wiring panel 40 is fixedly connected to the first slide rail 20 and the second slide rail 30, and the wiring panel 40 includes a terminal block 410 for threading an optical fiber 2. The winding mechanism 50 includes a front bracket 510 and a rear bracket 520 for winding the cable 1. One end of the rear bracket 520 is hinged to the guide rail 10, and the other end of the rear bracket 520 is hinged to one end of the front bracket 510. The other end of the front bracket 510 is hinged to the wiring panel 40 or the second slide rail 30.

[0031] According to the pull-out fiber optic patch panel in the above embodiment, the installer first pulls out the patch panel 40. The patch panel 40 is connected to the first slide rail 20 and the second slide rail 30. The first slide rail 20 is slidably connected to the first guide rail 110, and the second slide rail 30 is connected to the second guide rail 120, thus allowing the patch panel 40 to be pulled out. At this time, the front bracket 510 and the rear bracket 520 are straightened. The installer places the cable 1 on the front bracket 510 and the rear bracket 520, and leads out the optical fiber 2 from the cable 1 and passes it through the terminal block 410. Then, the installer pushes the patch panel 40 back. During the process of pushing the patch panel 40 back, one end of the rear bracket 520 is hinged to the guide rail 10, and the other end is hinged to one end of the front bracket 510. The other end of the front bracket 510 is hinged to either the patch panel 40 or the second slide rail 30. Therefore, the front bracket 510 and the rear bracket 520 will bend relative to each other, and the cable 1 set on the front bracket 510 and the rear bracket 520 will also be bent. Since the bending angle of the front bracket 510 and the rear bracket 520 is fixed, the bending arc of the cable 1 after bending is also fixed. This can avoid large errors caused by human operation, which could cause physical damage to the cable 1. The pull-out fiber optic patch panel in the embodiment can realize a fiber optic patch panel that is easy to pull out and does not require bending the cable 1 during installation.

[0032] It should be noted that, in order to increase the travel of the first slide rail 20 and the second slide rail 30, the first slide rail 20 and the second slide rail 30 can be multi-segment slide rails.

[0033] In some specific embodiments, the winding mechanism 50 further includes mounting members 530, which are respectively fixedly connected to the front bracket 510 and the rear bracket 520 to fix the cable 1.

[0034] Mounting component 530 is mainly for the convenient placement of cable 1, thereby achieving a relatively fixed cable 1.

[0035] In some specific embodiments, the mounting component 530 includes a first surface 5310 and a second surface 5320, wherein the first surface 5310 is connected to the second surface 5320 and the front bracket 510 or the rear bracket 520, respectively.

[0036] In this embodiment, the mounting member 530 and the front bracket 510, and the mounting member 530 and the rear bracket 520 respectively form a U-shaped groove. At this time, the cable 1 is placed in the U-shaped groove, thereby supporting the cable 1.

[0037] Generally, the mounting component 530, the front bracket 510, and the rear bracket 520 are also provided with multiple weight-reducing holes. On the one hand, the weight-reducing holes can be used to reduce the weight of the mounting component 530, the front bracket 510, and the rear bracket 520. On the other hand, cable ties can be used to thread through the weight-reducing holes to bind the cable 1 to the mounting component 530 or the front bracket 510 and the rear bracket 520.

[0038] It should be noted that the mounting component 530 can also be in other forms. For example, a corrugated tube can be used, and the cable 1 can be inserted into the corrugated tube to achieve constraint and fixation of the cable 1. As another example, the mounting component can be a snap fastener, which can engage with the front bracket 510 and the rear bracket 520 to achieve fixing and loosening of the cable 1.

[0039] In some specific embodiments, the top view projection of the second surface 5320 is located within the top view projection of the first surface 5310.

[0040] Cables 1 near both ends of mounting component 530 need to be bent with a certain curvature. The top view projection of the second surface 5320 is within the top view projection of the first surface 5310, meaning that neither end of the second surface 5320 extends beyond the ends of the first surface 5310. In this way, there is no obstruction from the second surface 5320 during the bending process of cable 1, allowing for a larger turning radius and ensuring that cable 1 will not be damaged by bending.

[0041] In some specific embodiments, the wiring panel 40 also includes a brush 420 disposed below the terminal block 410.

[0042] The 420 brush prevents dust from entering the fiber optic patch panel's fiber optic port and other areas, thus protecting the fiber optic 2 connectors and patch cord end faces from dust contamination. Dust adhering to the fiber optic 2 end face can cause signal attenuation or transmission interruption, affecting communication quality.

[0043] The 420 brush can be used to assist in the organization and management of patch cords. For example, in some patch panels, the bristles of the 420 brush can neatly comb and fix the patch cords, making them more organized. This prevents patch cords from becoming tangled and messy, facilitating maintenance and operation.

[0044] The brush 420 can also serve as a channel for jumpers, allowing jumpers to pass through its bristles for flexible wiring. This design ensures neat jumpers without obstructing airflow, thus aiding in heat dissipation.

[0045] In some specific embodiments, the wiring panel 40 further includes a drive member 430, which is toggled to move the wiring panel 40.

[0046] In this embodiment, the drive unit 430 allows the user to easily pull the wiring panel 40, thereby removing the wiring panel 40.

[0047] In some specific embodiments, the guide rail 10 is provided with an abutment portion 130, which is used to abut against the wiring panel 40 to prevent the wiring panel 40 from extending into the guide rail 10.

[0048] On the one hand, the abutment portion 130 prevents the wiring panel 40 from extending excessively into the junction box. On the other hand, the lengths of the front bracket 510 and the rear bracket 520 may exceed the distance between the first guide rail 110 and the second guide rail 120. The connection point of the front bracket 510 and the rear bracket 520 may touch the first guide rail 110, thereby damaging the cable 1. Essentially, when the abutment portion 130 abuts against the wiring panel 40, a predetermined safe distance is maintained between the connection point of the front bracket 510 and the rear bracket 520 and the first guide rail 110.

[0049] In some specific embodiments, when the wiring panel 40 abuts against the abutment portion 130, the bending radius of the cable 1 between the front bracket 510 and the rear bracket 520 is not less than 35mm.

[0050] The bending radius of cable 1 must be at least 30mm; otherwise, cable 1 will be bent and damaged. In this embodiment, through the design of the front bracket 510 and the rear bracket 520, when the wiring panel 40 and the abutment part 130 abut, the included angle between the front bracket 510 and the rear bracket is the smallest, and at this time, cable 1 is also bent to its maximum extent. At this time, the bending radius of cable 1 is not less than 35mm, which ensures that cable 1 will not suffer any physical damage.

[0051] In some specific embodiments, the terminals 410 are arranged in an array both horizontally and vertically.

[0052] To meet the functional requirements of the wiring panel 40 in terms of efficiency, orderliness, and ease of management in electrical connections, the terminal blocks 410 on it adopt an array arrangement in both the horizontal and vertical directions. Specifically, in the horizontal direction, the terminal blocks 410 are arranged sequentially at certain intervals according to electrical connection logic and signal transmission sequence, forming horizontal terminal groups, which facilitates the quick connection and identification of related lines on the same horizontal plane. In the vertical direction, the terminal blocks 410 are arranged according to different circuit zones or functional modules according to specific rules, forming vertical terminal groups, which helps to achieve classified management and maintenance of different circuit systems. This bidirectional array arrangement greatly improves the ease of use of the wiring panel 40 and the reliability of electrical connections.

[0053] In some specific embodiments, a connector 60 is also included for connecting the wiring panel 40 and the guide rail 10.

[0054] The connector 60 primarily serves as a connection, thereby increasing the strength of the connection between the guide rail 10 and the wiring panel 40. Furthermore, the front bracket 510 is typically mounted on the connector 60. This avoids requiring excessive drilling into the wiring panel 40, which would reduce the installation space for the adapter. Additionally, the front bracket 510 maintains a certain distance from the wiring panel 40, providing sufficient bending radius for the optical fiber 2.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
