That is, before the optical cable construction, the optical cable connectors are made at the two ends of the optical cable, and the optical, mechanical, environmental and other performance tests are performed, as shown in fig. 1A. This results in a longer cable for the distribution section that is carried to the job site. Due to the accuracy of the job site survey, a large excess length (e.g., 20 meters to 30 meters) typically remains after the cable assembly is completed. In the construction process of the optical cable of the distribution line segment, the optical cable is usually required to be coiled and carried to a construction site to implement optical cable installation work; and after the optical cables are installed, storing the redundant optical cables on a cable coiling frame, as shown in fig. 1B, wherein fig. 1B schematically shows a traditional cable coiling frame. Generally, the cable coiling frame and the optical cables are arranged independently, and when the optical cable assembling work is implemented on a construction site, all the optical cables need to be released completely, and then the redundant optical cables are coiled on the cable coiling frame again. Therefore, the construction time is prolonged seriously, and the construction efficiency is reduced. Therefore, how to improve the construction efficiency of the optical cable at the distribution section becomes a problem to be solved.

In a first possible implementation, the tray 101 is integrally formed with the first winding area 102.

In a second possible implementation, the tray 101 and the first winding area 102 may be detachable. In this implementation, the tray 101 may be provided with positioning columns 1011, as shown in fig. 4. The end surface of the first winding area 102 connected to the tray 101 may be provided with positioning holes. The first winding area 102 and the tray 101 can be fixedly connected through a positioning hole (not shown) provided on the positioning post 1011 and the first winding area 102 shown in fig. 4. A plurality of positioning columns 1011, such as three, four, etc., may be disposed on the tray 101. The positioning column can be in the shape of a triangular column, a cylinder and the like. The positioning columns can be arranged at equal intervals along the edge of the tray. In addition, the number of the positioning columns arranged on the tray 101 is not limited in the embodiment of the application, and the positioning columns are arranged according to the requirements of application scenes. It should be noted that, the number of the positioning posts disposed on the tray 101 is the same as the number of the positioning holes disposed in the first winding area 102, and the positions of the positioning posts correspond to each other, so as to achieve mutual fixing between the positioning posts and the positioning holes. In addition, when the tray 101 has a certain thickness, the tray 101 may also be provided with a plurality of positioning holes, and the end surface of the first winding area 102, which is connected to the tray 101, may also be provided with a corresponding number of positioning pillars, so as to realize the connection between the tray 101 and the first winding area 102.

In one possible implementation, the positioning region 103 and the first winding region 102 may be integrally formed, as shown in fig. 3.

In one possible implementation, the positioning region 103 and the first winding region 102 may be separated. In this implementation, the positioning region 103 may include a smooth end surface, which may have the same shape and size as the end surface of the first winding region 102 for connection with the positioning region 103. The end face of the positioning area 103 can also be provided with a positioning hole, and the end face connected with the positioning area 103 in the first winding area 102 can be provided with a positioning column, so that the positioning area 103 and the first winding area 102 are connected in a positioning manner through the positioning column and the positioning hole. The setting of the positioning posts on the end surface of the first winding area 102 connected to the positioning area 103 may refer to the setting of the positioning posts on the tray 101; the positioning holes in the positioning area 103 can be set by referring to the positioning holes in the end surface of the first winding area 102 connected to the tray 101, and are not described in detail herein.

Please refer to the positioning area 103 in fig. 3. A positioning shaft 1031 is also provided in the positioning region 103. The positioning shaft 1031 may be disposed on a side of the positioning region 103 away from the first winding region 102, and protrude outward from the positioning region 103. The positioning shaft 1031 may be cylindrical or quadrangular. The cylindrical shape is schematically shown in fig. 3. One end of the positioning shaft 1031 is fixed to an end surface of the positioning section 103 connected to the first winding section 102, and extends out from a side axially away from the first winding section 102, as shown in fig. 3, so that the second cable winding part 20 can be fitted over the positioning shaft 1031.

In a specific implementation, the positioning shaft 1031 may be provided with a first fixing member 1032, as shown in fig. 3. The second cable part 20 may be fixed to the first cable part 10 by a first fixing member 1032. The first fixing member 1032 may be an elastic clip, or may be another member having a fixing function.

In a first possible implementation manner, a plurality of first fixing members may be uniformly arranged along the circumferential direction of the positioning shaft 1031. The plurality of first fixing members may be, for example, two, three, or four, etc. The uniform arrangement may be, for example, equally spaced, symmetrically arranged, or oppositely arranged. For example, in the positioning shaft 1031 shown in fig. 3, two first fixing pieces 1032 may be included, one of which is shown in fig. 3, and the other may be disposed on the positioning shaft 1031 at a position opposite to the fixing pieces 1032. Wherein the fixing member 1032 may be disposed at a lateral middle position of the positioning shaft 1031.

In a second possible implementation manner, a plurality of first fixing members 1032 may be uniformly arranged along the circumferential direction of the positioning shaft 1031. The setting manner of the plurality of first fixing parts 1032 may refer to the setting manner of the plurality of first fixing parts 1032 in the first possible implementation manner, which is not described again. In addition, a plurality of second fixing members 1033 may be uniformly arranged along the circumferential direction of the positioning shaft 1031. In the axial direction of the positioning shaft 1031, one of the first fixing members 1032 and one of the second fixing members 1033 are arranged side by side at a spacing, as shown in fig. 5. A distance is provided between the first fixing member 1032 and the second fixing member 1033 arranged in the axial direction of the positioning shaft 1031. So that the first holder 1032 and the second holder 1033 in the axial direction can limit the nesting depth and the nesting position between the second cable part 20 and the first cable part 10. Therefore, the width of the first winding area 102 in the optical cable storage device 100 can be flexibly adjusted according to the length of the optical cable, so that the optical cable stored on the optical cable storage device 100 is more tidy, and the subsequent cable laying efficiency and the construction efficiency are improved.

With continued reference to the positioning region 103 shown in fig. 3 or 5. A restraint post 1034 is also disposed in the positioning region 103 in a region around the positioning axis 1031. The limiting column 1034 cooperates with the first fixing unit 1032 or the second fixing unit 1033 to further limit the nesting depth of the second cable part 20 and the first cable part 10. In a specific implementation, two of the limiting columns 1034 may be disposed, and the two limiting columns 1034 may be symmetrically disposed on two sides of the positioning shaft 1031, as shown in fig. 3 or fig. 5.

In addition, a positioning post 1035 is further disposed in the positioning area 103 at a peripheral region around the positioning shaft 1031. The positioning columns 1035 are used for further reinforcing the connection between the first cable coiling part 10 and the second cable coiling part 20, so that the second cable coiling part 20 is more firmly nested on the first cable coiling part 10, the optical cable is prevented from being loosened from each cable coiling part due to the fact that the second cable coiling part 20 slides down from the first cable coiling part 10, and the optical cable storage effect is favorably improved. In a specific implementation, the positioning posts 1035 may be disposed at edge positions of the end surface, such as four corners shown in fig. 3 or fig. 5.

Continuing to refer to fig. 6, a schematic diagram of the second cable tray portion 20 of the cable containment device 100 of fig. 2 is shown.

The second cable coiled section 20 includes a second spooling region 201, a first cable blocking region 202 and a second cable blocking region 203. Wherein, the first cable blocking area 202 and the second cable blocking area 203 are respectively disposed at two ends of the second winding area 201. After assembly between the first cable portion 10 and the second cable portion 20, the first cable blocking area 202 is located at an end of the second cable portion 20 close to the first cable portion 10, and the first cable blocking area 202 is in contact with the first cable portion 10; a second cable stop region 202 is located at an end of the second cable section 20 distal from the first cable section 10.

In one possible implementation, the second cable part 20 may be integrally formed.

In another possible implementation, the second winding area 201, the first cable blocking area 202 and the second cable blocking area 203 may be separated. Under this kind of implementation, the both ends of second wire winding district 201 can be provided with the reference column respectively, and the first optical cable stops that one side that the district is close to second wire winding district 201 to be provided with the locating hole, and second wire winding district 201 and first optical cable stop district 202 pass through reference column and locating hole assembly. Similarly, a positioning hole is formed in a side of the second cable blocking area 203 close to the second winding area 201, and the second winding area 201 and the second cable blocking area 203 are assembled through the positioning column and the positioning hole.

In the present embodiment, the second winding section 201 has a cylindrical shape, and is hollow inside for being nested to the positioning shaft 1031 of the first cable part 10. In a specific implementation, the second winding area 201 may be cylindrical, and may also be in other shapes, such as a square cylinder shape, a triangular cylinder shape, and the like, and the shape of the second winding area 201 is not particularly limited in this application. The second winding region 201 includes an outer wall 2011 and an inner wall 2012, as shown in fig. 7. Wherein the outer wall 2011 is used for stocking optical cables. The inner wall 2012 defines a plurality of engaging grooves for engaging with the first positioning members 1032 or the second positioning members 1033 on the positioning shaft 1031 of the first cable tray portion 10. In addition, the surface of the inner wall 2012 is provided with a plurality of position-limiting holes for inserting the position-limiting posts 1034 on the positioning region 103 to limit the nesting depth of the second cable part 20 in the first cable part 10.

In a first possible implementation manner, the plurality of limiting holes disposed on the surface of the inner wall 2012 can be through holes 20121, as shown in fig. 8. When the second cable coil part 20 is sleeved on the first cable coil part 10, the limiting column 1034 on the positioning region 103 in the first cable coil part 10 directly passes through the through hole on the inner wall of the second winding region 201, so as to realize the assembly between the second cable coil part 20 and the first cable coil part 10. Fig. 8 schematically shows a cross-sectional view of how the retainer post 1034 of the first cable drum 10 is fitted through the through-hole 20121 of the second cable drum 20.

In a second possible implementation manner, the plurality of limiting holes disposed on the surface of the inner wall 2012 can be blind holes 20122, as shown in fig. 9. When the second cable part 20 is sleeved on the first cable part 10, the limiting post 1034 on the positioning region 103 in the first cable part 10 is inserted into the blind hole on the inner wall of the second winding region 201, so as to realize the assembly between the second cable part 20 and the first cable part 10. Fig. 9 schematically shows a cross-sectional view of the manner in which the retaining stud 1034 of the first cable drum 10 is fitted through the blind hole 20122 of the second cable drum 20.

In a third possible implementation manner, the plurality of limiting holes are divided into two groups, one group of limiting holes is the through holes 20121, and the other group of limiting holes is the blind holes 20122, as shown in fig. 10. When the second cable drum 20 is sleeved on the first cable drum 10, one of the two sets of limiting holes is selected to insert the limiting post 1034 in the positioning region 103. The selection of the limiting hole is determined according to the length of the optical cable to be stored in the optical cable storage device 100. When the through hole 20121 is adopted, the limiting post 1034 on the positioning region 103 in the first cable part 10 can completely penetrate through the through hole 20121, so that a deeper embedding depth is provided between the first cable part 10 and the second cable part 20, the area of the first winding region 102 between the tray 101 and the first cable blocking region 202 is reduced, and the number of turns of the optical cables wound on the first winding region 102 is reduced. In this case, the optical cable is suitable for a case where the length of the optical cable is short. When the blind hole 20122 is adopted, after the limiting post 1034 on the positioning region 103 in the first cable part 10 is completely inserted into the blind hole 20122, the first cable part 10 and the second cable part 20 are not completely nested together due to the obstruction of the other end of the blind hole 20122. Compared with the through holes, the area of the first winding area 102 between the tray 101 and the first cable blocking area 202 is increased, and the number of turns of the cables stored in the first winding area 102 can be increased. In this case, the optical cable is suitable for a case where the optical cable is long. Through setting up two sets of spacing holes, can select which group's spacing hole that adopts according to the length of optical cable to can make the optical cable can be neatly store up in optical cable storage device 100, avoid the optical cable too short and the too big optical cable that leads to of wire winding district area to store up loosely, perhaps the optical cable is too long and wire winding district area undersize leads to unable the holding, thereby can improve the construction effect of optical cable.

It should be noted that, when a positioning element is disposed in the first cable winding part 10 along the axial direction of the positioning shaft 1031, the second winding area in the second cable winding part 20 may be disposed with a limiting hole of a through hole or a blind hole; when the positioning area 103 on the first cable winding part 10 is provided with a plurality of positioning elements along the axial direction of the positioning shaft, the second winding area in the second cable winding part 20 may be provided with two kinds of limiting holes, i.e., a through hole and a blind hole. In addition, when the second winding area in the second cable winding part 20 is provided with one of the through holes or the blind holes, the number of the positioning columns of the positioning area 103 on the first cable winding part 10 is the same as that of the limiting holes of the second winding area in the second cable winding part 20; when the second winding area in the second cable winding part 20 is provided with two kinds of limiting holes, namely a through hole and a blind hole, the number of the positioning columns of the positioning area 103 on the first cable winding part 10 is half of that of the limiting holes, and is the same as that of the through holes or that of the blind holes respectively. In addition, when the first positioning member 1032 is disposed in the axial direction of the positioning shaft 1031 in the first cable part 10 as shown in fig. 3 or 5, the position limiting hole disposed in the second cable part 20 may be a blind hole 20122, where the blind hole 20122 and the first positioning member 1032 cooperate with each other to assemble the first cable part 10 and the second cable part 20 as shown in fig. 9; when the second positioning member 1033 shown in fig. 5 is axially disposed on the positioning shaft 1031 in the first cable part 10, the limiting hole disposed in the second cable part 20 may be a through hole 20121, wherein the through hole 20121 and the second positioning member 1033 are mutually matched to assemble the first cable part 10 and the second cable part 20 as shown in fig. 8.

Continuing to refer to FIG. 11, a schematic diagram of the first cable stop region 202 of the second cable portion 20 is shown. First cable stop zone 202 may be a hollow structure. Along the radial direction of the second winding area 201, the first cable blocking area 202 is provided with a plurality of fan blades 2021, and the fan blades 2021 are perpendicular to the outer wall of the second winding area 201 and extend outwards from the outer wall 2011 of the second winding area 201. The fan blades 2021 are used for preventing the optical cables coiled in the first winding area 102 from sliding down to the second winding area 201, or preventing the optical cables coiled in the second winding area 201 from sliding down to the first winding area 102. The fan blades may include 2, 3, or 4 blades, and the like, which is not limited in this application. Fig. 11 schematically shows a case where the fan blades include 4. As shown in fig. 11, a communicating region 2022 connecting the first winding region and the second winding region is formed between any two adjacent fan blades 2021. Thus, the optical cable can be coiled in the first winding area 102 through the connection area 2022 after the second winding area 201 is partially coiled.

In a possible implementation, the second cable coiling part 20 is also provided with a first mounting hole. The first mounting hole is used for mounting a steel strip, so that the second cable coiling part 20 is arranged on a holding pole on a construction site through the steel strip.

In a specific implementation, the first mounting hole may be disposed on the fan blade 2021 of the first cable blocking area 202, as shown in fig. 11. In practice, a first mounting hole 2023 may be provided on one or more blades 2021, and the first mounting hole 2023 may extend through a short side of the blade. The first mounting hole 2023 may be disposed at a position where the fan blade is close to the second winding region 201. In fig. 11, a schematic structural diagram of two opposite fan blades 2021 provided with first mounting holes 2023 is schematically shown. In addition, the first mounting hole 2023 may be disposed at a middle position of the fan blade 2021. The present embodiment is not limited to this, and is set according to the needs of the scene. An assembly view between the second cable coiling section 20 and the steel band 200 is shown in fig. 12.

With continued reference to fig. 10, in fig. 10, the second cable blocking area 203 in the second cable coiling portion 20 is used for blocking the optical cables coiled in the second winding area 201 to prevent the optical cables from sliding off the second winding area 201. In a specific implementation, the second cable blocking area 203 may also be a hollow structure including a first surface for contacting the second winding area 201 and a second surface not contacting the second winding area 201. The second face not in contact with the second winding area 201 may also be referred to as an end face of the second cable winding part. An orthographic projection of the second cable stop region 203 onto the second spooling region 201 covers the second spooling region 201. In this way, the optical cable can be prevented from slipping off.

In a possible implementation, the surface of the second cable part 20 is further provided with a second mounting hole. The second mounting hole is used for mounting a cable hanging bracket, so that the second cable coiling part 20 can be arranged on the cable hanging bracket through the cable hanging bracket.

In particular implementations, a second mounting hole may be provided on a second side of the second cable blocking area 203, as shown in FIG. 10. In practice, two sets of second mounting holes 2031 may be provided, each set including two second mounting holes 2031, and the two sets of second mounting holes 2031 may be symmetrically provided on the second side of the second cable blocking area 203, as shown in fig. 10. In this embodiment, the position of the second mounting hole 2031 on the second surface of the second cable blocking area 203 is not specifically limited, and is set according to the requirement of the application scenario. An assembly view between the second coil cable part 20 and the cable hanger 300 is shown in fig. 13.

In one possible implementation, the second cable portion 20 is further provided with a wall-hanging mounting hole 2032, as shown in fig. 14. The wall-mounting hole 2032 may be disposed on the second side of the second cable stop area 203, or may be disposed on a side of the first cable stop area 202 that contacts the second winding area 201. When the wall-mounting hole 2032 is disposed on the first cable-blocking area 202 on the side contacting the second winding area 201, the area of the second cable winding area 202 where the wall-mounting hole 2032 is disposed is not covered by the second winding area 201. That is, when the second wire rope part 20 is installed, the wall-mounting hole 2032 may be exposed to the outside for wall-mounting.

As described above, fig. 15 shows the optical cable housing apparatus 100 according to the present embodiment after assembly. Therefore, after the optical cables are coiled and stored in the second winding area 201, the optical cables are continuously coiled and stored in the first winding area 102 through the optical cable routing area. During the cable pay-off process, the cable stored in the first winding area 102 may be first released. After the optical cables coiled in the first winding area 102 are released, the optical cables coiled in the second winding area 201 can be further released. After the optical cable that is needed in the construction site is released from the optical cable storage device 100, the second cable winding part 20 and the optical cables that are not released in the second cable winding part 20 are directly taken down from the optical cable storage device 100, that is, the second cable winding part 20 and the first cable winding part 10 are detached from each other, and a steel band is installed on the second cable winding part 20 through the first installation hole 2023, so that the second cable winding part 20 is hung on a pole in the construction site through the steel band, or a cable hanging bracket is installed on the second cable winding part 20 through the second installation hole 2031, so that the second cable winding part 20 is installed on a hanging cable in the construction site, or the second cable winding part 20 is installed on a wall through the wall hanging installation hole 2032. Therefore, the optical cable storage device 100 according to the embodiment of the present application does not need to complete the process of releasing all the optical cables and then re-storing the redundant optical cables during the construction process, thereby improving the construction efficiency.

In this embodiment, the optical cable storage apparatus 100 may further be provided with a storage box 30, as shown in fig. 16. The material of the receiving box 30 may be paper. After the optical cable is wound on the first winding portion 10 and the second winding portion 20, the first winding portion 10 and the second winding portion 20 may be disposed in the storage box 30.

Further, the second cable part 20 may be provided with a receiving box mounting hole 2033, as shown in fig. 14. After the first cable coiling part 10 and the second cable coiling part 20 are assembled, the accommodating box mounting hole 2033 formed in the second cable coiling part 20 can be fixed in the accommodating box 30, so that the optical cable is prevented from loosening due to shaking in the transportation process, and the accommodating efficiency of the optical cable in the transportation process is improved.

The storage box 30 is also provided with a folding region. As shown in fig. 16. By folding the folding area in the manner shown in fig. 16, the pre-connectorized splice of a cable can be pulled out of the cable routing area directly without removing the first cable portion 10 and the second cable portion 20 from the storage box, and the first cable portion 10 and the second cable portion 20 can be rotated within the carton, thereby allowing for a gradual cable payout.

Further, in order to ensure that the first cable winding part 10 and the second cable winding part 20 are more stable during the rotation process in the storage box, in a possible implementation manner, the optical cable storage device 100 may further be provided with a rotation shaft mounting hole, so that the first cable winding part 10 and the second cable winding part 20 can be inserted into the rotation shaft, and further the first cable winding part 10 and the second cable winding part 20 can rotate around the rotation shaft. In a specific implementation, a rotating shaft installation hole penetrating through the tray 101, the first winding area 102, the positioning area 103, the first cable blocking area 202, the second winding area 201 and the second cable blocking area 203 may be provided. The shaft mounting hole may be provided in a central region of each of the above-mentioned components. When the first cable winding part 10 and the second cable winding part 20 are installed in the storage box, the rotating shaft may be inserted into the rotating shaft installation hole and then fixed inside the storage box. Thereby make the first cable portion 10 of in-process that the optical cable pulled out from the containing box and second cable portion 20 more stable, and then make more smooth and easy putting the cable in-process.

While the present embodiments have been described with reference to the accompanying drawings, it is to be understood that the present embodiments are not limited to those precise embodiments, which are intended to be illustrative rather than restrictive, and that various changes and modifications may be effected therein by one skilled in the art without departing from the scope of the appended claims.
