[0029] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] In the related art, the handle of a conventional gel joint box is placed outside for a long distance, which occupies a large packaging volume and is inconvenient to transport. If the handle is completely hidden, it will cause inconvenience in rotation operation.

[0031] The embodiments of the present application provide a gel joint box and an optical cable connection device, which can solve the technical problems in the related art that the packaging volume of the gel box is large and the transportation is inconvenient.

[0032] See also Figures 1 to 3 As shown, a gel joint box provided by an embodiment of the present application may include: a cap barrel 1; and a gel compression assembly 2, wherein the gel compression assembly 2 is installed in the cap barrel 1, and the gel compression assembly 2 is installed with an operating handle 3, and the operating handle 3 can be extended to a first state relative to the gel compression assembly 2 along the axial direction of the operating handle 3, and can be retracted to a second state relative to the gel compression assembly 2 along the axial direction of the operating handle 3.

[0033] When the operating handle 3 is in the first state, the operating handle 3 can be rotated along the circumferential direction of the operating handle 3. When the operating handle 3 is not needed, the operating handle 3 can be pressed to retract the operating handle 3 to the second state. A gel sealing module 4 can be installed on the gel compression assembly 2. When the operating handle 3 is rotated along the circumferential direction of the operating handle 3, the gel compression assembly 2 can compress the gel sealing module 4 so that the gel sealing module 4 forms a seal with the side wall of the hat barrel 1 and the optical cable. A fiber tray assembly 8 and an optical cable fixing assembly 9 can also be provided in the hat barrel 1. The fiber tray assembly 8 is fixed to the gel compression assembly 2, and the optical cable fixing assembly 9 is also installed on the gel compression assembly 2 (see Figure 5 The gel joint box may also include an external optical cable fixing bracket 10, and the external optical cable fixing bracket 10 is also fixed with the gel compression assembly 2.

[0034] In this embodiment, the operating handle 3 is configured to be retractable relative to the gel compression assembly 2 along the axial direction of the operating handle 3, so that the operating handle 3 can be retracted to the second state when not in use and placed inside the hat barrel 1, so as to reduce the length and volume of the gel joint box, thereby reducing the volume of the transport package and improving the convenience of transportation; when the operating handle 3 is needed, the operating handle 3 is pulled out again, and the operating handle 3 is rotated to drive the gel compression assembly 2 to squeeze and seal the gel sealing module 4, and after sealing, the operating handle 3 can be pressed and compressed back to the second state to be shrunk and hidden, thereby solving the technical problem of the gel box in the related art that the packaging volume is large and the transportation is inconvenient.

[0035] See also Figure 2 As shown, in one embodiment, the gel compression assembly 2 may include a first pressing plate 21 and a second pressing plate 22, and a gel sealing module 4 is sandwiched between the first pressing plate 21 and the second pressing plate 22 (see Figure 4 and Figure 5 The operating handle 3 is installed on the first pressing plate 21 and the second pressing plate 22, that is, a part of the operating handle 3 is installed on the first pressing plate 21, and a part of the operating handle 3 is installed on the second pressing plate 22. When the operating handle 3 is in the first state and the operating handle 3 is rotated around the axis of the operating handle 3, the operating handle 3 drives the first pressing plate 21 and the second pressing plate 22 to move toward each other and squeeze the gel sealing module 4. In this embodiment, the gel compression assembly 2 is divided into two independent parts, and the two parts can slide relative to each other. The operating handle 3 drives the two pressing plates to squeeze the gel sealing module 4 to each other to achieve the sealing of the gel joint box.

[0036] Preferably, the first pressing plate 21 may be sleeved on the second pressing plate 22, so that the movement of the first pressing plate 21 can be guided. Of course, in some embodiments, the first pressing plate 21 may not be sleeved on the second pressing plate 22.

[0037] See also Figure 2 and Figure 3 As shown, in some optional embodiments, the operating handle 3 is provided with a spring sheet 5, wherein the spring sheet 5 can be installed to the side wall of the operating handle 3 by bolts, and when the operating handle 3 is retracted to the second state, the operating handle 3 is clamped in the gel compression assembly 2 by the spring sheet 5. The gel compression assembly 2 can be provided with a corresponding clamping position, and when the operating handle 3 moves along its axis to the clamping position where the spring sheet 5 is clamped into the gel compression assembly 2, the operating handle 3 cannot be extended and retracted along its axis due to the blocking of the spring sheet 5 by the clamping position, so that the operating handle 3 remains in the second state, that is, remains in the retracted and hidden position; when the operating handle 3 needs to be used, the operating handle 3 is pulled outward, so that the spring sheet 5 can be disengaged from the clamping position, and then the operating handle 3 is extended to the first state.

[0038] See also Figure 2 As shown, in one embodiment, the gel compression assembly 2 includes a first pressing plate 21 and a second pressing plate 22, the first pressing plate 21 is fixedly provided with a driving member 6, the operating handle 3 is mounted on the second pressing plate 22, and the operating handle 3 is connected to the driving member 6, when the operating handle 3 is in the first state, and the operating handle 3 is rotated around the axis of the operating handle 3, the operating handle 3 drives the first pressing plate 21 and the second pressing plate 22 to move toward each other. In this embodiment, by fixing the driving member 6 on the first pressing plate 21, the operating handle 3 indirectly drives the first pressing plate 21 to move by driving the driving member 6. In this configuration, the operating handle 3 does not need to directly contact the first pressing plate 21, which can reduce the wear of the first pressing plate 21 after long-term use.

[0039] For further information, see Figure 2 and Figure 3 As shown, in some optional embodiments, the operating handle 3 may include: a driving rod 31, the driving rod 31 is mounted on the second pressing plate 22, and the driving rod 31 can rotate relative to the second pressing plate 22 around the axis of the driving rod 31, the driving rod 31 is connected to the driving member 6, and a telescopic cavity 311 is provided in the driving rod 31, and the telescopic cavity 311 extends along the axis direction of the driving rod 31; and a telescopic handle 32, the telescopic handle 32 is accommodated in the telescopic cavity 311, and the telescopic handle 32 can extend out of the telescopic cavity 311 or retract into the telescopic cavity 311 along the axis direction of the driving rod 31, and the telescopic handle 32 can drive the driving rod 31 to rotate around the axis of the driving rod 31. In this embodiment, the connection with the second pressing plate 22 and the driving member 6 can be achieved by setting the driving rod 31, and the telescopic cavity 311 is set in the driving rod 31 to meet the extension and shortening of the operating handle 3, and the structure is simple.

[0040] Among them, an annular groove can be provided on the outside of the driving rod 31, and the annular groove extends around the circumferential direction of the driving rod 31. The second pressure plate 22 can be provided with a clamping block, and the clamping block is clamped in the annular groove so that the driving rod 31 is installed on the second pressure plate 22, and the driving rod 31 can rotate around the axis of the driving rod 31 relative to the second pressure plate 22, and the driving rod 31 and the second pressure plate 22 cannot move relative to each other in the axial direction.

[0041] See also Figure 2As shown, in one embodiment, the cross-section of the telescopic handle 32 located in the telescopic cavity 311 is non-circular, such as a hexagon or pentagon, and the inner contour of the telescopic cavity 311 matches the outer contour of the telescopic handle 32, so that the telescopic handle 32 can drive the drive rod 31 to rotate around the axis of the drive rod 31. When the telescopic handle 32 is set to a hexagonal structure, the telescopic cavity 311 is also set to a matching hexagonal structure, so that when the telescopic handle 32 rotates, the telescopic handle 32 can drive the drive rod 31 to rotate together, and the telescopic handle 32 can also move along its axis in the telescopic cavity 311. This embodiment realizes driving by matching the outer contour shape of the structure, and does not need to add new components to drive the telescopic handle 32 to drive the drive rod 31 to rotate, which can simplify the structure of the gel joint box and save materials.

[0042] In other embodiments, a longitudinal groove may be provided on the telescopic handle 32, and the groove extends along the axial direction of the telescopic handle 32. A protrusion may be provided in the telescopic cavity 311, and the protrusion may protrude into the groove. Such a setting may also enable the telescopic handle 32 to move in the telescopic cavity 311, and when the telescopic handle 32 rotates, it may drive the driving rod 31 to move together.

[0043] See also Figure 3 As shown, in some optional embodiments, the inner diameter of the telescopic cavity 311 gradually increases from one end of the telescopic cavity 311 toward the direction away from the first pressing plate 21. That is, in this embodiment, the portion of the driving rod 31 where the telescopic cavity 311 is provided can be injection molded, and the telescopic cavity 311 is not of equal size everywhere, the closer to the bottom surface of the telescopic cavity 311, the smaller the inner diameter, and the closer to the opening of the telescopic cavity 311, the larger the inner diameter, so that the inner wall of the telescopic cavity 311 forms a certain slope, so that the driving rod 31 is easy to open the mold during injection molding.

[0044] See also Figure 2 and Figure 3As shown, further, in one embodiment, the driving rod 31 may include: a stud 312, the stud 312 is threadedly connected to the driving member 6, and the driving member 6 is sleeved on the stud 312, wherein the driving member 6 is preferably a nut; a connecting rod 313, the connecting rod 313 is fixed to the stud 312, and the connecting rod 313 is provided with the telescopic cavity 311, and the telescopic handle 32 is inserted into the telescopic cavity 311 from the side of the connecting rod 313 away from the stud 312.

The outer surface of the stud 312 is formed with a thread, and the stud 312 has a high structural strength, and the connecting member can be molded by injection molding, so as to facilitate the formation of the telescopic cavity 311 inside it.

[0045] In other embodiments, the driving rod 31 may be entirely configured as an integrally formed injection molded part, and a thread may be formed on the driving rod 31 .
