Optical cable trays, optical fiber distribution boxes

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on February 22, 2024, with application number 202410201008.8 and invention name “Optical cable reel, optical fiber distribution box”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of optical communication equipment, and in particular to an optical cable reel for winding optical fibers, and an optical fiber distribution box modified from the optical cable reel. Background Art

[0003] Fiber optic distribution boxes, a key component of optical transmission equipment, are commonly used in fiber-to-the-home (FTTH) deployments. Currently, the fiber optic cable reel, access terminal box (ATB), and adapter are three separate components. On-site, the fiber optic cable reel and adapter must be installed inside the ATB.

[0004] This increases the number of assembly steps. Furthermore, due to the varying lengths of optical fibers, the cable reels also require different dimensions to accommodate the various specifications of the fiber optic distribution boxes. Therefore, the compatibility between the cable reel and the fiber optic distribution box must also be considered during assembly.

[0005] Summary of the Invention

[0006] The present application provides an optical cable reel, an optical fiber distribution box, and a method for assembling an optical cable reel into an optical fiber distribution box. The purpose is to provide an optical cable reel that can be converted into an optical fiber distribution box, reducing the number of assembly steps and eliminating the need to consider the matching of the optical cable reel and the optical fiber distribution box.

[0007] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0008] In one aspect, the present application provides an optical cable reel that can be converted into an optical fiber distribution box.

[0009] The optical cable reel comprises: a first structural portion and a second structural portion arranged opposite to each other, and a cable reel shaft, wherein the cable reel shaft is connected between the first structural portion and the second structural portion, and the periphery of the cable reel shaft forms a storage space for winding the optical fiber; the edge of at least one structural portion of the first structural portion and the second structural portion comprises a bending portion, and the bending portion can be bent toward the other structural portion, and the bent portion after bending forms a side wall of the storage space, and the optical cable reel further comprises a connecting structure, and the connecting structure is used to connect the bent portion after bending with another structural portion, or the connecting structure is used to connect the bent portion after bending of the first structural portion with the bent portion after bending of the second structural portion.

[0015] Since the edge of the first structural part has a bent portion, a cutout portion can be provided on the edge of the second structural part to prevent the bent portion from protruding relative to the second structural part and to improve the overall strength of the optical cable reel. During modification, the cutout portion of the second structural part can be removed and the bent portion can be reconnected to the second structural part.

[0021] When the optical fiber distribution box is brought into the home, an adapter needs to be installed. Therefore, a fixing structure for installing the adapter is provided on the optical cable reel provided in the present application, so that the adapter can be directly assembled after the optical cable reel is modified.

The cable drum shaft and the inner shaft are connected via a connecting plate. The inner shaft passes through the first structural portion and the second structural portion.

[0036] In some structures, the first structural part faces the user, and the second structural part faces away from the user and is fixedly connected to the wall, so that the connection terminals located in the installation groove are hidden on the inner side of the device, which can improve the appearance.

[0037] In one practicable manner, the connection structure includes a slot and a buckle, one of the slot and the buckle is provided on the bent portion, and the other is provided on the other structural portion.

[0093] In optical transmission equipment, an access terminal box (ATB) needs to be installed. For example, the ATB can be used in a fiber-to-the-home scenario or can be installed outdoors.

[0094] In the fiber optic distribution box, an optical cable reel with optical fibers wound on it can be installed. A connection terminal connected to the optical fiber, such as an adapter, can also be installed in the fiber optic distribution box. The adapter is connected to the optical fiber on the user side.

[0095] An embodiment of the present application provides an optical cable reel structure, which can not only coil optical fibers but also be converted into an optical fiber distribution box. That is, by modifying one part, it not only maintains its original function of carrying optical fibers but also saves another part to achieve another function.

[0096] The structure that can be realized by the optical cable reel is described in detail below with reference to the accompanying drawings.

[0097] As shown in Figures 1 and 2, Figures 1 and 2 illustrate one embodiment of an optical cable reel. Figure 2 illustrates the structure of the first structural portion of the optical cable reel. In this example, the optical cable reel comprises: a first structural portion 1 and a second structural portion 2 arranged opposite each other (face to face), and a reel shaft 3 connected between the first and second structural portions 1 and 2. The reel shaft 3 is used to coil optical fibers, and the outer periphery of the reel shaft 3 forms a storage space 4 for accommodating the coiled optical fibers. In other words, the optical cable reel shown in Figure 1 functions as a reel for optical fibers.

[0098] In the example of the present application, an edge of at least one of the first structural portion 1 and the second structural portion 2 includes a bent portion 5 .

[0099] For example, as shown in Figures 1 and 2, the edge of the first structural part 1 includes a bent portion 5, and the edge of the second structural part 2 does not include the bent portion 5; for another example, the edge of the second structural part 2 includes a bent portion 5, and the edge of the first structural part 1 does not include the bent portion 5; for another example, as shown in Figure 3, the edge of the first structural part 1 includes a bent portion 5, and the edge of the second structural part 2 also includes a bent portion 5.

[0100] As shown in FIG4 (A), taking the bent portion 5 as an example, which is provided at the edge of the first structural portion 1, the bent portion 5 can be bent toward the second structural portion 2. The bent portion 5 is used to form the side wall of the coil storage space 4, surrounding the coil storage space 4. After the bent portion 5 is connected to the second structural portion 2, the optical fiber distribution box structure can be modified as shown in FIG4 (B).

[0101] Returning to Figure 3, when the edge of the first structural part 1 and the edge of the second structural part 2 both include a bending portion 5, the bending portions 5 on the two structural parts are bent relative to each other and connected, and can be modified into the optical fiber distribution box structure shown in (B) in Figure 4.

[0102] In some usage scenarios, such as fiber-to-the-home scenarios, when installing a fiber optic distribution box, the operator winds the optical fiber around the optical cable reel as shown in (A) in Figure 4 provided in this application, then bends the bent part 5 and fixes it to another structural part to convert it into a fiber optic distribution box.

[0103] Compared with the existing assembly solution, there is no need to assemble independent optical cable reel parts on independent optical fiber distribution boxes, and there is no need to consider whether the size of the optical cable reel matches the size of the optical fiber distribution box.

[0104] Therefore, the solution provided in this application for converting an optical cable reel into an optical fiber distribution box can reduce the number of parts, lower costs, and improve assembly efficiency.

[0105] Returning to FIG. 2 , there are multiple bent portions 5 , which are arranged at intervals along the circumference of the edge of the first structural portion 1. For example, when the modified optical fiber distribution box is a rectangular parallelepiped or a cube, there are four bent portions 5 , which are arranged at intervals along the circumference of the edge of the first structural portion 1, with adjacent bent portions 5 separated.

[0106] In order to increase the strength of the optical cable reel, as shown in FIG2 , two adjacent bending portions 5 are connected by a connecting portion 6 , and the connecting portion 6 is detachably connected to the bending portion 5 , that is, the connecting portion 6 can be removed from the bending portion 5 .

[0107] During modification, the connecting portion 6 between two adjacent bent portions 5 can be removed, and then the bent portions 5 can be bent.

[0108] The connecting portion 6 may be a plate member with an arc-shaped structure as shown in FIG. 2 , or may be other shapes.

[0109] In some examples, when the edge of the first structural portion 1 includes a bent portion 5 and the edge of the second structural portion 2 does not include the bent portion 5, the bent portion 5 on the first structural portion 1 protrudes from the edge of the second structural portion 2. This not only affects the aesthetic appearance, but also reduces the strength of the entire optical cable reel.

[0110] Based on this, as shown in Figures 5 and 6, a removed portion 7 can be provided at the edge of the second structural portion 2. For example, the edge of the orthographic projection of the bent portion 5 on the removed portion 7 can coincide with the edge of the removed portion 7, that is, as shown in Figure 5, the outer side surface of the bent portion 5 is flush with the outer side surface of the removed portion 7.

[0111] 5 and 6 , when modified, the connecting portion 6 in the first structural portion 1 is removed, and the removal portion 7 in the second structural portion 2 is removed, and then the bent portion 5 is bent. The bent portion 5 is fixedly connected to the second structural portion 2 after the removal portion 7 is removed to form a fiber optic distribution box.

[0112] In the example of the present application, the bent portion 5 provided at the edge of the structural portion has a variety of achievable structures, and several examples are given below.

[0113] In some examples, as shown in Figures 7 and 8, Figure 7 is a top view of Figure 6 of the example of the present application, and Figure 8 is a cross-sectional view along the AA direction of Figure 7. A bent portion is formed by providing a non-through groove on the structural portion. For example, the first structural portion 1 has a first surface and a second surface facing back to back, and the first surface is farther away from the second structural portion 2 than the second surface; along the circumference of the first structural portion 1, a groove 8 is provided on the first surface, and there is a gap between the bottom surface of the groove 8 and the second surface, that is, the groove does not penetrate the first structural portion 1, and the edge of the first structural portion 1 can be bent toward the second structural portion 2 along the groove 8 to form a bent portion 5.

[0114] In other examples, a rotating shaft can be used to rotatably connect the bending portion 5 to the first structural portion 1. The bending portion 5 can rotate around the rotating shaft toward the second structural portion 2 and can be connected to the second structural portion 2 to form a fiber optic distribution box.

[0115] When a connecting portion 6 is provided between two adjacent bending portions 5 provided in the embodiment of the present application, the connecting portion 6 and the bending portion 5 may be detachably connected in a variety of ways.

[0116] An example is shown in Figure 9, which shows a structural diagram of the first structural part 1. Figure 9 also shows the details of the connection between the connecting part 6 and the bending part 5. A groove can be opened between the bending part 5 and the connecting part 6, and the groove passes through the first structural part. A connecting rib 9 is set in the groove, and the bending part 5 and the connecting part 6 are connected by the connecting rib 9.

[0117] In another example, a groove may be provided between the bent portion 5 and the connecting portion 6 . The groove does not pass through the first structural portion, and the depth of the groove is relatively deep, so that the connecting portion 6 can be removed relatively easily.

[0118] As shown in Figure 10, when the edge of the second structural part 2 of the example of the present application does not have a bent part but has a removed part 7, the connection method of the removed part 7 and the structural part can be: there is a gap 10 between the removed part 7 and the edge of the second structural part 2, and a plurality of connecting ribs 11 are arranged at intervals in the gap 10, and the removed part 7 is connected to the second structural part 2 through the connecting ribs 11.

[0119] After the bending portion 5 is bent, it can be fixedly connected to another structural portion using a connecting structure 12. For example, as shown in Figures 10 and 11, and Figure 12, Figure 10 shows a structural diagram of the second structural portion 2, Figure 11 shows a structural diagram of the first structural portion 1, and Figure 12 shows a structural diagram of the modified optical fiber distribution box. The connecting structure 12 includes a slot 121 and a buckle 122. One of the slot 121 and the buckle 122 can be set on the bending portion 5, and the other can be set on the other structural portion. In the examples of Figures 10 and 11, the slot 121 is opened on the bending portion 5 of the first structural portion 1, and the buckle 122 is set on the second structural portion 2. For another example, the slot 121 can be set on the second structural portion 2, and the buckle 122 can be set on the bending portion 5.

[0120] In one example, when both the edge of the first structural portion 1 and the edge of the second structural portion 2 have a bent portion 5, the slot 121 can be provided on the bent portion 5 of the first structural portion 1, and the buckle 122 can be provided on the bent portion 5 of the second structural portion 2. After the two bent portions 5 are bent, they can be connected by the slot 121 and the buckle 122, so that the two bent portions 5 are fixed.

[0121] There can be multiple slots 121 and multiple buckles 122, multiple slots 121 are distributed at intervals along the circumference of the bending part 2, multiple buckles 122 are distributed at intervals along the circumference of the second structural part 2, and multiple buckles 122 are arranged on the side of the second structural part 2.

[0122] The use of matching card slots and buckles not only simplifies the structure, but also makes it easy to operate when converted into a fiber optic distribution box.

[0123] As shown in Figure 10, when the edge of the second structural part 2 has a removed portion 7, the buckle 122 can be set in the gap 10. When the removed portion 7 is removed, the slot 121 on the bent portion 5 can be engaged with the buckle 122 to modify it into the structure shown in Figure 12.

[0124] When the optical fiber distribution box is in use, a connection terminal connected to the optical fiber needs to be installed. The connection terminal also needs to be connected to the optical fiber on the user side. For example, the connection terminal includes an adapter.

[0125] In the example of the present application, a fixing structure for fixing the connecting terminal is also provided on the optical cable drum, and a mounting groove can be provided on the first structural part 1 or the second structural part 2, as shown in Figures 13 and 14. Figure 13 shows a structural diagram of the back of the second structural part 2, that is, a structural diagram of the side of the second structural part 2 away from the first structural part 1, and Figure 14 shows the structure of the back of the optical fiber distribution box, which can be understood as the M-direction view of Figure 12. In some examples, the first structural part 1 faces the user, and the second structural part 2 faces the installation wall. A mounting groove 13 is provided on the side of the second structural part 2 away from the first structural part 1, and a connecting terminal 14 (such as an adapter) can be provided in the mounting groove 13. That is, hiding the connecting terminal 14 on the back of the optical fiber distribution box can not only protect the connecting terminal, but also improve the appearance of the distribution box.

[0126] In some examples, as shown in FIG13 , a card slot 15 may be provided on the wall surface surrounding the installation slot 13 , and a protrusion that can be snapped into the card slot 15 is provided on the connection terminal 14 . The connection terminal 14 is fixedly installed by the cooperation between the card slot 15 and the protrusion.

[0127] Since the optical fiber wound on the cable drum shaft needs to be connected to the connecting terminal 14, in some structures, as shown in Figure 13, a wire hole 16 can be opened on the second structural part 2, and one end of the optical fiber wound on the cable drum shaft can pass through the wire hole 16 and be connected to the connecting terminal 14 located in the installation groove 13.

[0128] As shown in Figure 14, an example of the present application is to set the installation groove for installing the connecting terminal 14 on the second structural part 2, and the bending part 5 located at the edge of the first structural part 1 is bent toward the second structural part 2. Then, as shown in Figure 14, a removable part 20 can be set on the bending part 5. After the bending part 5 is bent, the removable part 20 blocks the groove opening of the installation groove. When the connecting terminal 14 installed in the installation groove needs to be connected to the optical fiber on the user side, the removable part 20 can be removed.

[0129] In the optical cable reel provided in the present application, as shown in FIG15 , an inner shaft 17 is provided in the cable reel shaft 3 . The inner shaft 17 is a hollow structure. The cable reel shaft 3 and the inner shaft 17 are connected by a connecting plate 18 . The inner shaft 17 passes through the first structural part 1 and the second structural part 2 .

[0130] There can be multiple connecting plates 18 , and the multiple connecting plates 18 are arranged at intervals along the circumference of the inner shaft 17 to improve the connection strength between the inner shaft 17 and the cable drum shaft 3 .

[0131] When winding the optical fiber on the optical cable drum shown in FIG. 15 , the inner shaft 17 may be used to place the optical cable drum on a structure, and the optical cable drum may be rotated to wind the optical fiber onto the drum shaft 3 .

[0132] After the optical cable reel provided in the present application is converted into a fiber optic distribution box, the fiber optic distribution box needs to be fixed, for example, it needs to be fixed on the desktop or wall on the user side.
