Description

Technical Field

[0001] This invention relates to the field of standard cabinet fiber optic patch cord storage technology, specifically to a screw-out fiber optic patch cord excess length storage system and method. Background Technology

[0002] As enterprises continue to deepen their digital transformation, enterprise communication networks, as the infrastructure of enterprise digital systems, are becoming increasingly faster and larger in scale. Various types of optical fiber cables, due to their excellent transmission performance and low price, have almost become the only choice for enterprise network transmission media.

[0003] When building an enterprise network, due to the numerous and widely distributed locations, limited server room space, and diverse equipment, standard 19-inch racks are typically chosen to install IT equipment and fiber optic termination equipment. Fiber optic patch cords are used within the racks or cabinet groups to complete communication connections and fiber optic cable splices. However, standard fiber optic patch cords are usually of fixed length (e.g., 3m, 5m, 10m), and standard racks using ODF (Optical Distribution Frame) lack fiber optic patch cord length control devices. This results in uncontrollable excess length, leading to messy and unsightly redundant patch cords hanging haphazardly within the rack, which also creates significant maintenance difficulties. Summary of the Invention

[0004] The purpose of this invention is to provide a screw-out fiber optic patch cord storage system and method that can not only meet the basic function of storing excess fiber optic patch cord length, but also has a large capacity, small footprint, and makes fiber optic patch cords less prone to misalignment and easy to maintain, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A screw-out fiber optic patch cord extension storage system includes a fixed housing assembly and a screw-out tray assembly, as well as at least one and at most 24 fiber optic patch cord extension winding shaft assemblies. The fiber optic patch cord extension winding shaft assemblies are arranged inside the screw-out tray assembly for storing fiber optic patch cords. The screw-out tray assembly is hinged and rotated inside the fixed housing assembly. The fixed housing assembly is mounted to a corresponding position on a vertical component group inside a cabinet via L-shaped side mounting brackets and fasteners. The fiber optic patch cord extension winding shaft assemblies and cabling inside the screw-out tray assembly can be screwed out as a whole when the screw-out tray is screwed out.

[0007] Furthermore, the main body of the fixed box assembly is a fixed box sheet metal part. The front corner of the fixed box sheet metal part is machined with three holes, one of which is a first through hole and two of which are second through holes. Two small nails are welded on the two second through holes to form hinge nails, and a small nail is welded on the one first through hole as a screw-out and screw-in stop nail for the rotating disc assembly.

[0008] Furthermore, each side of the hinge pin is provided with an inlet / outlet hole, and a rubber single-sided protective coil is installed on the inlet / outlet hole. Similarly, each side of the hinge pin is provided with an inlet / outlet hole, and a rubber single-sided protective coil is installed on the inlet / outlet hole. A push-type door lock hanging hole is opened on the front of the opposite side plate of the hinge pin.

[0009] Furthermore, the fixed box sheet metal part is machined with left and right upper folded edges and a rear folded edge. The bottom of the rear folded edge is used to insert the top plate. The front part of the top plate covers the left and right upper folded edges, and the top plate is fixed to the upper part of the fixed box sheet metal part using two flat-head screws through the two third through holes of the left and right upper folded edges.

[0010] Furthermore, the main body of the rotating disk assembly is a sheet metal bending part. The left, right, rear and upper inner sides of the sheet metal bending part are machined with long grooves for fixing fiber optic jumpers when wiring inside the disk. A hinge hanging hole is opened on the hinge side of the front of the sheet metal bending part, and the rotating disk assembly is hung on the hinge nail through the hinge hanging hole.

[0011] Furthermore, the sheet metal bending part has an arc-shaped rotating disk stop groove concentric with the hinge side, which fits into the stop pin and is used for the rotating disk assembly to stop rotating out and in; the sheet metal bending part also has a push-type door lock mounting hole on the opposite side of the front hinge, and a push-type door lock is installed on the push-type door lock mounting hole. The opening and closing of the rotating disk assembly is realized by sliding the push-type door lock. A set of binding wires for fixing fiber optic patch cords during wiring is also spot-welded in the middle part of the rotating disk assembly.

[0012] Furthermore, the fiber optic patch cord excess winding shaft assembly is an I-beam shaft made of ABS / PS plastic with an outer diameter of 60mm. A thin steel ring is attached to the outside of one side plate of the I-beam shaft, and 3-4 thin rubber magnetic sheets are evenly attached to the corresponding positions of the thin steel ring on the other side plate.

[0013] Furthermore, the thin rubber circular magnetic sheet is attached to the inside of the sheet metal bending part, while the thin rubber circular magnetic sheet of another winding shaft is adsorbed onto the thin steel ring of the winding shaft, for the stacking arrangement of the fiber optic patch cord excess length winding shaft assembly.

[0014] This invention provides another technical solution: a method for storing excess fiber optic patch cord length, based on a screw-out fiber optic patch cord excess length storage system, comprising the following steps:

[0015] Step 1: Install the mounting box assembly onto the vertical component assembly inside the 19-inch standard rack using the L-shaped side mounting brackets and fasteners.

[0016] Step 2: Fix the fiber optic patch cord to the component or other cabinet accessories, and after routing the cable to the vicinity of the fixed box assembly, group it into a fiber optic patch cord inlet bundle, and then enter the unscrewed tray assembly inside the box from the inlet hole on the side of the fixed box assembly.

[0017] Step 3: The fiber optic patch cord is laid along the side using a side-winding wiring method or a front-winding wiring method within the rotating tray assembly.

[0018] Step 4: After the excess length of the fiber optic patch cord is led out from the side or front wiring in sequence, it is wound around the corresponding fiber optic patch cord excess length winding shaft assembly.

[0019] Step 5: After the fiber optic patch cord is unwound from the spindle assembly, it is fixed on the binding line in the middle of the spindle. The fiber optic patch cords are grouped on the binding line in the middle to form the middle cable group.

[0020] Step 6: The intermediate cabling group is led out from the cable outlet hole of the fixed box to form a fiber optic patch cord bundle. The fiber optic patch cord bundle is fixed to the component or other cabinet accessories and the cabling is routed to the equipment interface.

[0021] Furthermore, during the process of storing excess fiber optic patch cords, when the rotating tray assembly is in the rotating or closed state, the bending radius of all fiber optic patch cords is not less than their minimum bending radius, and the force they are subjected to is not greater than their maximum force.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. The screw-out fiber optic patch cord excess length storage system and method of the present invention, through the screw-out structural design, makes the fiber optic patch cord excess length storage box relatively closed, which can protect the safe placement of fiber optic patch cord excess length. Moreover, the internal wiring method can completely screw out the screw-out tray, which is convenient for operators to lay or maintain. The wiring system adopts the method of laying the incoming and outgoing lines separately, which is clear, uninterrupted, and convenient for checking and maintaining the lines.

[0024] 2. The spin-out fiber optic patch cord excess length storage system and method of the present invention allows the incoming line to be wound to the winding shaft by either side or front when wiring in the spin-out reel. At this time, the corresponding outgoing line adopts the middle wiring. If the incoming line is laid in the middle, the corresponding outgoing line can be laid by front or side winding. The whole design occupies little space, has a large capacity, and is easy to operate, maintain and replace. Attached Figure Description

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] like Figure 1-2As shown, this embodiment of the invention provides a screw-out fiber optic patch cord excess length storage system, including a fixed housing assembly 1 and a screw-out tray assembly 2, as well as at least one and at most 24 fiber optic patch cord excess length winding shaft assemblies 3. The fiber optic patch cord excess length winding shaft assemblies 3 are arranged inside the screw-out tray assembly 2 for storing fiber optic patch cords. The screw-out tray assembly 2 is rotatably mounted inside the fixed housing assembly 1 via a hinge. The fixed housing assembly 1 is mounted to the corresponding position of the vertical component group inside the cabinet via an L-shaped side mounting piece 151 and fasteners. The fiber optic patch cord excess length winding shaft assemblies 3 placed inside the screw-out tray assembly 2 and the wiring inside the tray can be screwed out as a whole as the screw-out tray is screwed out. The fixed housing assembly 1 and the screw-out tray assembly 2 are assembled to form a screw-out fiber optic patch cord excess length storage box, which has a simple structure, is easy to assemble, and is convenient to use.

[0039] Specifically, such as Figure 3-4 As shown: In the above embodiment, the main body of the fixed box assembly 1 is a fixed box sheet metal part 11. The front corner of the fixed box sheet metal part 11 has three holes: one is a first through hole 111, and two are second through holes 112. Two small nails are welded to the two second through holes 112 to form hinge nails 13. One small nail is welded to the first through hole 111 as a screw-in / screw-out stop nail 12 for the rotating disc assembly 2.

The left and right upper folded edges and the rear folded edge are machined on the fixed box sheet metal part 11. The bottom of the rear folded edge is used to insert the top plate (not shown in the figure). The front of the top plate covers the left and right upper folded edges, and the top plate is fixed to the upper part of the fixed box sheet metal part 11 by two flat-head screws 162 through the two third through holes 115 of the left and right upper folded edges.

[0040] like Figure 5-6As shown: In this embodiment of the invention, the main body of the rotating disk assembly 2 is a sheet metal bending part 21. The sheet metal bending part 21 has long grooves 213 machined on its left, right, rear, and upper inner front edges for fixing fiber optic jumpers during internal wiring. A hinge hanging hole 211 is opened on the hinge side of the front of the sheet metal bending part 21.

A set of fiber optic patch cords 22 for fixing fiber optic patch cords during wiring is also spot welded in the middle part of the rotating disc assembly 2, so as to fix fiber optic patch cords during wiring.

[0041] like Figure 7-8 As shown: In this embodiment of the invention, the fiber optic patch cord excess length winding shaft assembly 3 is an I-shaped shaft 31. The material of the I-shaped shaft 31 is ABS / PS plastic, and the outer diameter of the cylinder is 60mm, which meets the minimum bending radius requirement of the fiber optic patch cord. A thin steel ring 32 is attached to the outer side plate of one side plate of the I-shaped shaft 31, and 3-4 thin rubber magnetic sheets 33 are evenly attached to the corresponding positions of the thin steel ring 32 on the outer side plate of the other side plate. The I-shaped shaft 31 can be arranged at an appropriate position in the rotating disc body and attached to the inner side of the sheet metal bending part 21 by the thin rubber magnetic sheets 33. At the same time, the thin rubber magnetic sheets 33 of the other winding shaft are attracted to the thin steel ring 32 of the winding shaft, which can realize the superimposed arrangement of the fiber optic patch cord excess length winding shaft assembly 3.

[0042] Working principle: The spin-out fiber optic patch cord excess length storage system of the present invention includes a spin-out disc assembly 2 which is mounted on a hinge hanging hole 211 and a spin-out / screw-in stop pin 12 in a fixing box, enabling the spin-out disc assembly 2 to be opened and closed; the spin-out disc assembly 2 is fitted with an arc-shaped spin-out disc stop groove 212 and a hinge pin 13, enabling the spin-out disc to be stopped at the open and closed positions; when the spin-out disc is closed, a push-type door lock 23 installed on one side can slide in the push-type door lock mounting hole 214 and then pop out and hang in the push-type door lock hanging hole 116 on the side plate of the fixing box, thereby closing the fiber optic patch cord excess length storage box; the fiber optic patch cord excess length winding shaft assembly 3 is arranged inside the spin-out disc assembly 2 after winding the fiber optic patch cord excess length, and moves with the spin-out disc.

[0043] like Figure 9-11 As shown: To further explain and better illustrate the embodiments of the present invention, a method for storing excess fiber optic patch cord length is also provided, which is implemented based on a screw-out fiber optic patch cord excess length storage system, and includes the following steps:

[0044] Step 1: Install the fixed housing assembly 1 on the vertical component assembly inside the 19-inch standard rack using the L-shaped side mounting bracket 151 and fasteners.

[0045] Step 2: Fix the fiber optic patch cord to the component or other cabinet accessories, and after wiring to the vicinity of the fixed box assembly 1 to form a fiber optic patch cord inlet bundle 41, enter the rotating tray assembly 2 inside the box from the inlet hole on the side of the fixed box assembly 1.

[0046] Step 3: The fiber optic patch cord is laid along the side using the side-winding wiring method 421 or the front-winding wiring method 422 within the rotating disc assembly 2.

[0047] Step 4: The excess length of the fiber optic patch cord is sequentially led out from the side winding cable 421 or the front winding cable 422 and then wound around the corresponding fiber optic patch cord excess length winding shaft assembly 3.

[0048] Step 5: After the fiber optic patch cord is wound out from the spin-out tray assembly 2, it is fixed on the binding line 22 in the middle of the spin-out tray. The fiber optic patch cords are grouped on the binding line 22 in the middle to form the middle cable group 52.

[0049] Step 6: The intermediate cabling group 52 is led out from the cable outlet hole of the fixed box to form a fiber optic patch cord cable bundle 51. The fiber optic patch cord cable bundle 51 is fixed to the component or other cabinet accessories and the cabling is routed to the equipment interface.

[0050] During the process of storing excess fiber optic patch cords, regardless of whether the rotating disk assembly 2 is rotated out or closed, the bending radius of all fiber optic patch cords is not less than their minimum bending radius, and the force they are subjected to is not greater than their maximum force.

[0051] In summary, the present invention provides a screw-out fiber optic patch cord excess length storage system and method. Through its screw-out structural design, the fiber optic patch cord excess length storage box is relatively enclosed, protecting the safe placement of excess fiber optic patch cords. Furthermore, the internal wiring method allows the screw-out tray to be completely screwed out, facilitating wiring and maintenance by operators. The wiring system uses separate inlet and outlet cables, ensuring clarity and preventing interference, thus facilitating cable inspection and maintenance. Secondly, when wiring within the screw-out tray, the inlet cable can be wound sideways or forward onto the winding shaft, with the corresponding outlet cable using center wiring. If the inlet cable is laid in the center, the corresponding outlet cable can be wound forward or sideways. The overall design occupies little space, has a large capacity, and is easy to operate, maintain, and replace.
