Description

Technical Field

[0001] This utility model relates to the field of optical fiber communication cables, and in particular to an optical fiber communication cable junction box. Background Technology

[0002] A fiber optic cable junction box is a device used to connect the backbone fiber optic cable and the distribution fiber optic cable in a fiber optic communication system. It is usually installed on the ground floor of a building or outdoors. The junction box provides physical support for the fiber optic cable, ensuring that the fiber optic cable is not damaged by excessive bending, stretching or compression during connection and branching. By fixing the fiber optic cable in a specific position inside the junction box, the stability of the fiber optic cable is guaranteed during long-term use.

[0003] In the prior art, although the cables in the communication cable junction box are arranged in an orderly manner, the orderly arrangement of the optical cables can be easily disrupted when the junction box is impacted or when it encounters bumps during transportation. When inspecting, repairing or replacing the optical cables later, it is difficult for operators to find the target optical cable. In addition, heavier equipment, such as optical splitters, is directly placed in the junction box. When the junction box is impacted, the equipment is easily damaged by collision with the box. Therefore, this application provides a communication optical cable junction box to meet the requirements. Utility Model Content

[0004] The technical problem this utility model aims to solve is to provide a communication optical cable junction box to address the issue that, although the cables in existing communication cable junction boxes are arranged in an orderly manner, the orderly arrangement of optical cables is easily disrupted when the junction box is impacted or encounters bumps during transportation. This makes it difficult for operators to locate the target optical cable during subsequent inspection, maintenance, or replacement. Furthermore, heavier equipment, such as optical splitters, is directly placed inside the junction box, and collisions between the equipment and the box can easily cause damage when the junction box is impacted.

[0005] To solve the problems mentioned above, this utility model is implemented through the following technical solution.

[0006] A communication optical cable junction box, comprising:

[0007] First installation board;

[0008] The first mounting plate has a sliding groove inside, and an optical splitter body is mounted on the upper end of the first mounting plate. A spring is in contact with one side of the optical splitter body, and a connecting piece is welded to the side of the spring away from the optical splitter body.

[0009] Second installation board;

[0010] A bearing rod is provided on one side of the upper end of the second mounting plate, and an opening and closing limiting plate is provided on the outer end of the bearing rod. A limiting circular groove is formed at the lower end of the opening and closing limiting plate and the corresponding position of the upper end of the second mounting plate.

[0011] In one embodiment, a connecting hinge is connected to one side of the housing, and an opening and closing door is connected to the other side of the connecting hinge.

[0012] In one embodiment, a rubber pad is glued and fixed to the side of the door near the housing.

[0013] In one embodiment, when the door is closed, the rubber pad on one side of the door is in contact with the side of the optical splitter body away from the spring.

[0014] In one embodiment, the cross-sectional structure of the lower end slider of the optical splitter body matches the cross-sectional structure of the groove opened inside the first mounting plate.

[0015] In one embodiment, the side of the connecting piece away from the spring is welded and fixed to the inner wall of the housing.

[0016] In one embodiment, the lower ends of both sides of the bearing rod are welded and fixed to the second mounting plate.

[0017] In one embodiment, the bearing rod extends through the interior of one side of the opening and closing limiting plate, and the opening and closing limiting plate can rotate outside the bearing rod.

[0018] In one embodiment, the lower end of the opening and closing limiting plate and the upper end of the second mounting plate are provided with limiting grooves, both of which are semicircles with the same radius.

[0019] This utility model provides a communication optical cable junction box. Compared with the prior art, it has the following advantages:

[0020] In the above scheme, when the junction box is subjected to external impact, the optical splitter body will move within the slide groove, and the spring will be compressed and deformed. This process can effectively absorb and dissipate the energy generated by the impact, reduce the impact force transmitted to the optical splitter body, and protect the optical splitter from damage. The slide groove and the spring work together to firmly fix the optical splitter body on the first mounting plate, avoiding problems such as excessively small fiber bending radius and loose interfaces caused by equipment shaking, thereby improving the quality and efficiency of optical signal transmission. The optical cable is placed in the limiting circular groove. The groove wall of the limiting circular groove can provide a certain physical barrier for the optical cable, preventing external objects from directly colliding with or squeezing the optical cable. The optical cable is placed relatively neatly in the limiting circular groove, and it is not easy to bend excessively, thereby ensuring stable transmission of optical signals. The limiting circular groove can arrange the optical cable in an orderly manner, avoiding the mess of optical cables. This not only makes the wiring inside the junction box neater and more beautiful, but also makes it easier for operators to find the target optical cable when it is necessary to inspect, repair or replace the optical cable, thus improving work efficiency.

[0029] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0030] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0031] Reference Figures 1-6 A communication optical cable junction box, comprising:

[0032] First installation board 5;

[0033] The first mounting plate 5 has a sliding groove 6 inside. The optical splitter body 7 is mounted on the upper end of the first mounting plate 5. A spring 9 is in contact with one side of the optical splitter body 7. A connecting piece 10 is welded to the side of the spring 9 away from the optical splitter body 7.

[0034] The groove 6 inside the first mounting plate 5 provides a space for relative sliding of components such as the optical splitter body 7. One side of the optical splitter body 7 is in contact with a spring 9. The elasticity of the spring 9 allows it to be compressed when subjected to pressure and to return to its original shape when the pressure is removed. The connecting piece 10 can transfer the elastic force of the spring 9 to other related structures, thereby dispersing and transmitting the elastic force and further stabilizing the position of the optical splitter body 7.

[0035] Second installation board 11;

[0036] A bearing rod 12 is provided on one side of the upper end of the second mounting plate 11. An opening and closing limiting plate 13 is provided on one side of the outer side of the bearing rod 12. A limiting groove 14 is provided at the lower end of the opening and closing limiting plate 13 and at the corresponding position of the upper end of the second mounting plate 11.

[0037] The optical cable is placed in the limiting circular groove 14. The groove wall of the limiting circular groove 14 can provide a certain physical barrier for the optical cable, preventing external objects from directly colliding with or squeezing the optical cable. The optical cable is placed relatively in a standardized manner in the limiting circular groove 14, and it is not easy to bend excessively, thereby ensuring the stable transmission of optical signals. The limiting circular groove 14 can arrange the optical cable in an orderly manner, avoiding the optical cable being messy. This not only makes the wiring inside the junction box neater and more beautiful, but also makes it easier for operators to find the target optical cable when it is necessary to inspect, repair or replace the optical cable, thus improving work efficiency.

[0038] like Figure 1 As shown, a connecting hinge 2 is connected to one side of the box body 1, and an opening and closing door 3 is connected to the other side of the connecting hinge 2.

[0039] like Figure 5 As shown, a rubber pad 4 is glued and fixed to the side of the opening and closing door 3 near the box body 1.

[0040] like Figure 5 As shown, when the door 3 is closed, the rubber pad 4 on one side of the door 3 is in contact with the side of the optical splitter body 7 away from the spring 9.

[0041] A rubber pad 4 is glued and fixed on the side of the opening and closing door 3 near the housing 1. When the opening and closing door 3 is closed, the rubber pad 4 will fit tightly against the side of the optical splitter body 7 away from the spring 9. Since the rubber pad 4 has a certain degree of elasticity and softness, it can fill the gap between the opening and closing door 3 and the optical splitter body 7 during the fitting process, thereby achieving a good sealing effect. When the opening and closing door 3 is closed, the tight fit between the rubber pad 4 and the optical splitter body 7 can provide additional protection for the internal fiber optic equipment. When the junction box is hit or vibrated, the rubber pad 4 can play a buffering role, absorbing and dispersing part of the impact force, reducing the risk of damage to the optical splitter and other sensitive equipment.

[0042] like Figure 3 and Figure 6 As shown, the cross-sectional structure of the slider 8 at the lower end of the optical splitter body 7 matches the cross-sectional structure of the groove 6 opened inside the first mounting plate 5.

[0043] The cooperation between the slider 8 and the groove 6 enables the optical splitter body 7 to be precisely positioned during installation. Furthermore, during subsequent use and maintenance, the position of the optical splitter body 7 remains relatively stable and will not shift due to equipment vibration or minor collisions. This helps to ensure the accuracy and reliability of the fiber optic connection and reduces the risk of optical signal loss or interruption caused by changes in the position of the optical splitter.

[0044] like Figure 2 and Figure 4 As shown, the side of the connecting piece 10 away from the spring 9 is welded and fixed to the inner wall of the housing 1.

[0045] The side of the connecting piece 10 away from the spring 9 is welded and fixed to the inner wall of the housing 1. This connection method allows the connecting piece 10 to reliably transmit the force generated by the spring 9 to the housing 1, while also providing additional stability and strength to the entire structure. When the optical splitter body 7 is subjected to external force, the connecting piece 10 can disperse and bear part of the external force through its fixed connection with the housing 1, reducing the shaking and deformation of the optical splitter body 7 and ensuring its normal operation.

[0046] like Figure 6 As shown, the lower ends of both sides of the bearing rod 12 are welded and fixed to the second mounting plate 11.

[0047] like Figure 6 As shown, the bearing rod 12 passes through the interior of one side of the opening and closing limiting plate 13, and the opening and closing limiting plate 13 can rotate outside the bearing rod 12.

[0048] like Figure 2 As shown, the lower end of the opening and closing limiting plate 13 and the upper end of the second mounting plate 11 are respectively provided with limiting circular grooves 14, which are semicircles with the same radius.

[0049] During use, when opening the hinged door 3, apply a suitable force to rotate it around the connecting hinge 2 to open the door 3. Then, install the cable. The bearing rod 12 at the upper end of the second mounting plate 11 provides a rotation fulcrum for the opening and closing limiting plate 13. Rotate the opening and closing limiting plate 13 around it. When the opening and closing limiting plate 13 is in the appropriate position, its lower end aligns with the limiting circular groove 14 at the corresponding position on the upper end of the second mounting plate 11, forming a relatively closed and stable limiting space. Place the optical cable in the limiting circular groove 14. The groove wall of the limiting circular groove 14 can provide a certain physical barrier for the optical cable. To prevent external objects from directly colliding with or squeezing the optical cable, the optical cable is placed relatively neatly within the limiting circular groove 14, making it less prone to excessive bending. The sliding groove 6 inside the first mounting plate 5 provides a relatively sliding space for components such as the optical splitter body 7. A spring 9 is in contact with one side of the optical splitter body 7. The elastic characteristics of the spring 9 allow it to be compressed when subjected to pressure and return to its original shape when the pressure is removed. The connecting piece 10 can transfer the elastic force of the spring 9 to other related structures, playing a role in dispersing and transmitting the elastic force, thereby further stabilizing the position of the optical splitter body 7.
