Description

Technical Field

[0001] The invention relates to the technical field of distribution frames, in particular to an optical fiber distribution frame. Background Art

[0002] Fiber Optic Distribution Frame (FODF) is a device used to manage, store and protect fiber connection points. It plays a vital role in modern communication networks, especially in data centers, local area networks (LANs), wide area networks (WANs), metropolitan area networks (MANs) and access networks. FODF usually includes multiple modular trays or drawers, which can easily insert and remove fiber jumpers.

[0003] In the actual application of the patch panel, the optical fibers are usually sorted and bundled into bundles and stored in the patch panel. However, this approach has certain shortcomings: when a specific optical fiber needs to be troubleshooted, maintained or replaced, since the optical fibers are densely bundled together to form a bundle, it is not only difficult to remove the target optical fiber individually, but it is also easy to cause the optical fiber to be entangled or even knotted, which brings inconvenience to the inspection and maintenance work.

[0004] Based on this, the invention discloses an optical fiber distribution frame. Summary of the invention

[0005] In order to solve the problem that the distribution frame proposed in the background technology bundles and stores optical fibers densely, which leads to the problem that the optical fibers are difficult to disassemble and easy to be entangled and knotted when troubleshooting or maintaining a single optical fiber, the existing optical fiber bundling and storage method has room for improvement in flexibility and operability, so as to improve the convenience and efficiency of single optical fiber processing and reduce the risk of optical fiber damage caused by improper operation; the present invention provides an optical fiber distribution frame, which includes a distribution frame body, and a plurality of port card holders for clamping optical fiber terminals are arranged at the ports of the distribution frame body, and the port card holders are divided into two layers;

[0006] On this basis, in order to route the wires behind the partially connected optical fiber terminals, it is first necessary to separate these wires one by one and pre-fix the separated wires;

[0007] As a further improvement of the technical solution, a first wiring assembly is arranged at the rear end of the port socket in the wiring frame body, wherein the first wiring assembly includes a first wiring board fixed in the wiring frame body and adapted to the width of the wiring frame body, the first wiring board, the first wiring board is provided with two rows of first accommodating openings corresponding to each other in the longitudinal direction, the top of the first wiring board is provided with a plurality of first guide grooves connected with the first accommodating openings in the first row from top to bottom, and the first guide grooves correspond one-to-one with the first accommodating openings in the first row; the top of the first wiring board is also provided with a plurality of second guide grooves connected with the first accommodating openings in the second row, the second guide grooves correspond one-to-one with the first accommodating openings in the second row, and the second guide grooves are in an S-shaped structure.

[0008] In this technical solution, after the wire adjacent to the optical fiber terminal is limited and fixed, in order to facilitate further arrangement of the subsequent wires, the subsequent arrangement of the wires needs to first complete the winding and limiting of the longer part, so the wire located in the first receiving opening will have a certain angle deviation;

[0009] As a further improvement of the present technical solution, a first rubber sleeve is fixedly provided on a side of the first accommodating opening away from the port holder, a notch is opened on the first rubber sleeve, and the first rubber sleeve is made of rubber; secondly, the first rubber sleeve has a conical structure, and the inner diameter of one end of the first rubber sleeve away from the port holder is smaller than the first accommodating opening, and the inner diameter of the smaller end of the first rubber sleeve is adapted to the outer diameter of the optical fiber.

[0010] After the wires near the optical fiber terminals are separated one by one and fixed in the first step, the longer wires behind need to be arranged;

[0011] As a further improvement of the technical solution, a winding assembly is provided at the rear end of the first wiring board in the wiring frame body, and the winding assembly includes a plurality of symmetrically arranged rows of first winding parts, a second winding part is provided between the first winding parts, and an S-shaped optical fiber winding route is formed between the first winding parts and the second winding parts; wherein, the first winding part and the second winding part each include a plurality of fixing rings, the fixing ring is provided in the wiring frame body, a notch is provided at the top of the fixing ring, a plurality of dividing grooves are provided on one side of the fixing ring, and the dividing grooves on the fixing ring in the first winding part and the dividing grooves on the fixing ring in the second winding part are arranged opposite to each other.

[0012] In another technical solution, after the wire is wound around the first winding part and the second winding part, only a few wire ends are left at the end of the wire, the wire ends are left out and the final limit fixation is performed to ensure that the wires wound around the first winding part and the second winding part can be neatly and individually stuck on the corresponding dividing grooves;

[0013] As a further improvement of the technical solution, a second wiring assembly is arranged in the wiring frame body at the rear end of the winding assembly, and the second wiring assembly includes a second wiring board fixed in the wiring frame body and adapted to the width of the wiring frame body, a plurality of second rubber sleeves are evenly fixed on the second wiring board, and a plurality of third guide grooves corresponding to and connected to the second rubber sleeves are opened at the top of the second wiring board; wherein, a notch is opened at the top of the second rubber sleeve, and the inner diameter of the second rubber sleeve is adapted to the outer diameter of the optical fiber.

[0014] After the wire is inserted into the second rubber sleeve, it is ensured that the wire can only be further stretched and tightened, while the wire is retracted to cause the wire in the first winding part and the second winding part to become loose;

[0015] As a further improvement of the present technical solution, several rows of circumferential limit strips are arranged in the second rubber sleeve, the limit strips are L-shaped, and the horizontal end of the L-shaped structure of the limit strip points to the direction in which the optical fiber passes out, and the limit strips are made of flexible material.

[0016] As a further improvement of the technical solution, two groups of third wiring components are symmetrically arranged at the rear end of the second wiring board in the wiring frame body, and the third wiring component includes a fixed plate fixed in the wiring frame body, and a plurality of rows of third wiring boards are evenly fixed on the fixed plate, and a plurality of second accommodating openings are evenly opened on the third wiring boards, and a plurality of notches corresponding to the second accommodating openings and connected to the second accommodating openings are opened at the top of the fixed plate, and the inner diameter of the second accommodating openings is adapted to the outer diameter of the optical fiber.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In this fiber optic distribution frame, efficient fiber optic wiring and management are achieved through winding components, an S-shaped wiring path is adopted, and the cooperation between the first winding part and the second winding part enables the optical fiber to be evenly distributed in the internal space of the distribution frame. At the same time, the design of the dividing groove allows the optical fiber to flexibly adjust its position as needed; the efficiency and neatness of the fiber optic wiring are greatly improved, so that specific optical fibers can be quickly located and processed during later maintenance, solving the problem of difficulty in quickly finding the target optical fiber in traditional methods.

[0019] 2. In this fiber optic distribution frame, a first rubber sleeve is used to protect and limit the optical fiber in the first accommodating port. The first rubber sleeve is designed to be a conical structure with a notch, which is convenient for providing a certain angle of movement after the optical fiber enters, and at the same time limits the position of the optical fiber to prevent it from being damaged due to angle deviation; the stability of the optical fiber in the first accommodating port is enhanced, the physical damage that may be caused in subsequent operations is reduced, and the long-term reliability of the optical fiber connection is ensured.

[0020] 3. In this fiber optic distribution frame, the second wiring assembly is implemented to further ensure the stability and maintainability of the optical fiber. The third guide groove on the second wiring board guides the optical fiber into the second rubber sleeve. The latter has a built-in L-shaped limit strip, which effectively prevents the optical fiber from retracting and ensures the firmness of the cable arrangement; it ensures the stable layout of the optical fiber in the distribution frame, and can maintain a good condition even under long-term use or external interference, reducing the difficulty of maintenance.

[0021] 4. In this fiber optic distribution frame, the third wiring component provides simple and effective wire end management, and the optical fiber end is simply fixed through the second receiving port to facilitate subsequent operations such as wiring. This step simplifies the final wire end processing flow, making the maintenance of the entire system more intuitive and efficient, and also leaves convenience for future expansion.

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] The existing distribution frame stores optical fibers in dense bundles, which makes it difficult to disassemble and easy to get tangled when troubleshooting or maintaining a single optical fiber.

[0044] To this end, the present invention provides a fiber optic distribution frame, see Figure 1-Figure 2 As shown, it includes a distribution frame body 1, and a plurality of port card holders 2 for connecting optical fiber terminals are arranged at the ports of the distribution frame body 1, and the port card holders 2 are divided into two layers;

[0045] When in use, the optical fiber terminal is fixed by clamping it on the port holder 2, and when installing it, it needs to be clamped up and down in sequence starting from one side, two by two. That is to say, for this double-layer port holder 2, after every two or four clamps are connected, the wire at the rear end of the optical fiber terminal needs to be pulled out to start fixing and limiting. If too many are clamped at one time, knots are likely to occur during subsequent wiring.

[0046] In order to route the wires behind the partially connected optical fiber terminals, it is first necessary to separate the wires one by one and pre-fix the separated wires;

[0047] Reference Figure 4-Figure 5 As shown, a first wiring assembly 3 is provided in the wiring frame body 1 at the rear end of the port card seat 2, wherein the first wiring assembly 3 includes a first wiring board 31 fixed in the wiring frame body 1 and adapted to the width of the wiring frame body 1, the first wiring board 31, and the first wiring board 31 is provided with two rows of first accommodating openings 33 corresponding to each other in the longitudinal direction, and the top of the first wiring board 31 is provided with a plurality of first guide grooves 32 connected with the first accommodating openings 33 of the first row from top to bottom, and the first guide grooves 32 correspond one-to-one with the first accommodating openings 33 of the first row; the top of the first wiring board 31 is also provided with a plurality of second guide grooves 34 connected with the first accommodating openings 33 of the second row, and the second guide grooves 34 correspond one-to-one with the first accommodating openings 33 of the second row, and the second guide grooves 34 are S-shaped structures.

[0048] After the wires of the fixed optical fiber terminals are pulled out, the wires of the first row of the port holder 2 are first inserted from the first guide groove 32 into the first accommodating opening 33, and then the wires of the second row of the optical fiber terminals of the port holder 2 are inserted from the second guide groove 34 into the first accommodating opening 33 directly below the first accommodating opening 33 of the first row. The S-shaped structure of the second guide groove 34 facilitates the neat insertion of the wires of the second row of optical fiber terminals on the port holder 2 into the first accommodating opening 33 directly below the first accommodating opening 33 of the first row. This one-to-one correspondence facilitates the subsequent wiring of longer wires, and at the same time, when maintenance is required in the later stage, it can also ensure that the wires can be wired and limited one by one in the position near the optical fiber terminals.

[0049] When the wires near the optical fiber terminal are limited and fixed, in order to facilitate further arrangement of the subsequent wires, the subsequent arrangement needs to first complete the winding and limiting of the longer part. Therefore, the wires located in the first accommodating opening 33 will have a certain angle deviation. In order to protect this part that is always in an angle deviation, it is necessary to add a first rubber sleeve 35 to protect the wires located in the first accommodating opening 33. At the same time, the wires located in the first accommodating opening 33 are further limited to ensure that during the subsequent winding process, the wires near the optical fiber terminal position can be in a certain stable condition to prevent damage to the optical fiber terminal during subsequent winding.

[0050] Reference Figure 6As shown, the first rubber sleeve 35 is fixedly arranged on the side of the first receiving opening 33 away from the port holder 2, and a notch is opened on the first rubber sleeve 35. The first rubber sleeve 35 is made of rubber. Secondly, the first rubber sleeve 35 is in a conical structure, and the inner diameter of the end of the first rubber sleeve 35 away from the port holder 2 is smaller than the first receiving opening 33. The inner diameter of the smaller end of the first rubber sleeve 35 is adapted to the outer diameter of the optical fiber.

[0051] When in use, while the wire is inserted into the first receiving opening 33 from the first guide groove 32 and the second guide groove 34, the wire is also inserted into the first rubber sleeve 35 from the notch of the first rubber sleeve 35. The rubber material of the first rubber sleeve 35 provides a certain movable angle for the wire near the first receiving opening 33. Secondly, the narrower end of the conical structure of the first rubber sleeve 35 provides a certain limit for the wire near the optical fiber terminal, so that the wire in the first receiving opening 33 maintains a certain stability.

[0052] After the wires near the optical fiber terminals are separated one by one and fixed in the first step, it is necessary to arrange the longer wires at the back so that they are neatly arranged in the wiring frame body 1. At the same time, it is necessary to cooperate with the first rubber sleeve 35 to ensure that the wires corresponding to the optical fiber terminals can still be separated one by one and accurately found during the later maintenance. It is also necessary to avoid excessive cumbersomeness in the process of arranging the wires to affect efficiency.

[0053] That is to say, the conical structure of the first rubber sleeve 35 provides progressive limiting and stress buffering for the optical fiber at the first accommodating opening 33; the material properties (elastic deformation) of the conical rubber sleeve 35 absorb the bending stress of the optical fiber and reduce the insertion loss degradation caused by angle deviation.

[0054] Reference Figure 1-Figure 3 and Figure 7-Figure 10 As shown, a winding assembly 4 is provided at the rear end of the first wiring board 31 in the distribution frame body 1, and the winding assembly 4 includes a plurality of symmetrically arranged rows of first winding parts 43, and a second winding part 44 is provided between the first winding parts 43, and an S-shaped optical fiber winding route is formed between the first winding parts 43 and the second winding parts 44; wherein, the first winding parts 43 and the second winding parts 44 both include a plurality of fixing rings 41, and the fixing ring 41 is provided in the distribution frame body 1, and a notch is provided at the top end of the fixing ring 41, and a plurality of dividing grooves 42 are provided on one side of the fixing ring 41, and the dividing grooves 42 on the fixing ring 41 in the first winding part 43 and the dividing grooves 42 on the fixing ring 41 in the second winding part 44 are arranged opposite to each other.

[0055] like Figure 8The dotted line portion is shown as a winding method for the wires. The S-shaped wiring allows longer wires to be neatly arranged in the limited wiring frame body 1. The specific winding method is to first start from one side of the first wiring board 31, evenly divide the wires into several groups, and then make the number of wires in the fixing ring 41 as equal as possible, and then directly insert the wires from the notch of the fixing ring 41 into the dividing groove 42 one by one, and after completing the clamping of the wires of the fixing ring 41 in the first winding part 43, the wires are clamped into the fixing ring 41 in the second winding part 44, and then the wires are pulled in the reverse direction and clamped into the fixing ring 41 in the first winding part 43 behind the second winding part 44, as shown in FIG. Figure 8 The dotted line wiring is arranged in the same way as the subsequent wiring, and the wiring on the other side of the first wiring board 31 starts from the edge of the other half that is symmetrical to the center of the winding component 4; after the wire is inserted into the fixing ring 41, since the fixing ring 41 is annular and there are several dividing grooves 42 at the positions where the wire and the fixing ring 41 are in contact, it is only necessary to simply roughly separate the wires to distinguish different heights. After the subsequent wires are further fixed, they are finely wired so that the positions of the wires in the fixing ring 41 are arranged in sequence from top to bottom, and when the rear end of the wire is not limited, it only needs to be roughly separated.

[0056] like Figure 1 and Figure 11-Figure 12 As shown, after the wire is wound around the first winding part 43 and the second winding part 44 and only a few wire ends are left at the end of the wire, the wire ends are left out and the final limit fixation is performed to ensure that the wires wound around the first winding part 43 and the second winding part 44 can be neatly and singly stuck on the corresponding dividing groove 42. Therefore, a second wiring assembly 5 is provided at the rear end of the winding assembly 4 in the wiring frame body 1. The second wiring assembly 5 includes a second wiring board 51 fixed in the wiring frame body 1 and adapted to the width of the wiring frame body 1. A plurality of second rubber sleeves 53 are evenly fixed on the second wiring board 51. A plurality of third guide grooves 52 corresponding to and connected to the second rubber sleeves 53 are provided at the top of the second wiring board 51. A notch is provided at the top of the second rubber sleeve 53, and the inner diameter of the second rubber sleeve 53 is adapted to the outer diameter of the optical fiber.

[0057] After the wire is inserted into the second rubber sleeve 53, it is ensured that the wire can only be further stretched and tightened, and the wire is recovered, resulting in the wire in the first winding part 43 and the second winding part 44 being loose. A plurality of rows of circumferential limiting strips 54 are arranged in the second rubber sleeve 53. The limiting strips 54 are L-shaped, and the horizontal end of the L-shaped structure of the limiting strips 54 points to the direction of the optical fiber passing out. The limiting strips 54 are made of flexible material.

[0058] In this way, after the ends of the wires are inserted into the second rubber sleeve 53 from the third guide groove 52 one by one, the wires are tightened and stretched one by one. While stretching, the wires are separated from the dividing groove 42 in the fixing ring 41 from top to bottom or from bottom to top, so that they fall into the dividing groove 42. It is not necessary to separate the wires one by one. It is sufficient to ensure that the wires are separated in a gradient from top to bottom. This reduces cumbersome installation and improves efficiency. After separation, the ends of the wires are further stretched to make them stuck in the second rubber sleeve 53. Since the second rubber sleeve 53 has an L-shaped limit strip 54, when the wires are stretched and tightened, the wires can be stretched and fixed along the structure of the limit strip 54. However, if the wires need to be recovered, the existence of the limit strip 54 will increase the reverse friction, making it difficult for the wires to be easily recovered without the action of external force, thereby ensuring the stability of the wires in the first winding part 43 and the second winding part 44.

[0059] That is to say, the winding component 4 adopts a symmetrical layout of an S-shaped fixing ring 41 and a dividing groove 42 to guide the redundant optical fibers to be wound in layers according to a gradient; the second rubber sleeve 53 of the second wiring component 5 integrates an L-shaped limit strip 54 to form a unidirectional friction locking mechanism, and the S-shaped winding path maximizes the use of the three-dimensional space of the distribution frame body 1. The gradient distribution of the dividing groove 42 avoids micro-bending losses caused by inter-fiber squeezing; the L-shaped limit strip 54 uses a flexible material and a reverse resistance design to prevent topological loosening caused by cable retraction during maintenance, thereby improving the reliability of dynamic adjustment.

[0060] like Figure 13-14 As shown, after all the wires are separated, wound, and fixed one by one according to the above steps, the remaining wire ends need to be simply fixed to facilitate other subsequent processes, such as wiring, so as to facilitate the subsequent processing. Therefore, two groups of third wiring components 6 are symmetrically arranged at the rear end of the second wiring board 51 in the wiring frame body 1. The third wiring component 6 includes a fixed plate 61 fixed in the wiring frame body 1, and a plurality of rows of third wiring boards 62 are evenly fixed on the fixed plate 61. A plurality of second accommodating openings 63 are evenly opened on the third wiring board 62. A plurality of notches corresponding to the second accommodating openings 63 and connected to the second accommodating openings 63 are opened at the top of the fixed plate 61. The inner diameter of the second accommodating opening 63 is adapted to the outer diameter of the optical fiber line.

[0061] As for the last remaining wire end, it is only necessary to simply insert the wire directly from the notch on the second receiving opening 63 into the second receiving opening 63 to achieve simple limiting, which is convenient for finding the wire end later. A plurality of rows of third wiring boards 62 are provided, and a plurality of second receiving openings 63 are provided on the third wiring boards 62. In this way, it is convenient for the wire end to be accurately inserted in a straight line. It is only necessary to simply press the wire against the fixing plate 61 roughly, and the wire end of the wire will be inserted into part of the second receiving opening 63 to achieve limiting of the wire end.

[0062] That is to say, the third wiring assembly 6 discretely fixes the wire ends through multiple rows of second receiving openings 63, and the terminal discrete fixing mode (second receiving openings 63) ensures a one-to-one mapping between the physical position of the wire ends and the logical ports, thereby shortening the time spent on troubleshooting.

[0063] In summary, by optimizing the arrangement, fixation and protection mechanism of the optical fibers, especially by introducing innovative designs such as the port holder 2, the first wiring assembly 3, the first rubber sleeve 35, the winding assembly 4, the second wiring assembly 5 and the third wiring assembly 6, the problems of difficulty in disassembly and easy entanglement and knotting caused by dense bundling of optical fibers in the prior art are systematically solved. In terms of overall operation, it not only improves the installation efficiency and maintenance convenience of the optical fiber network, but also significantly enhances the reliability and durability of the optical fiber connection. That is to say, through the optical fiber management route of layered card connection (port card holder 2) → path isolation (first wiring component 3) → redundant storage (winding component 4) → end locking (second wiring component 5) → line head calibration (third wiring component 6), a physical layer decoupled optical fiber arrangement architecture is constructed. Through segmented fixation and independent fiber channel design, single fiber quick plug-in and pull-out is achieved (the efficiency is improved by more than 60% compared with the traditional method), and the S-shaped winding and the gradient distribution of the dividing groove 42 enable a 1U rack to support a 96-core wiring density while retaining 30% redundant adjustment space. Secondly, the composite protection mechanism of the rubber sleeve (35, 53) and the limit strip 54 reduces the signal loss caused by external force disturbance to <0.2dB; finally, the systemic defects such as inefficient maintenance, difficult fault location and limited scalability caused by rigid bundling in the prior art are solved.
