Description

Technical Field

[0002] With the widespread popularization of computers and the rapid development of network technology, the network can be used to quickly obtain information or provide services, and optoelectronic communication can provide fast and large-scale information transmission. The light sources of optical fiber cable communication are mainly light-emitting diodes and laser diodes. Since laser diodes have the advantages of high output power, fast transmission speed, small light-emitting angle and narrow spectrum (smaller dispersion), they are more suitable for medium and long-distance transmission. As for light-emitting diodes, they are more suitable for short-distance transmission due to their low cost and easier use (simple driving and compensation circuits).

[0003] As an important part of the optical fiber cable communication system, the optical fiber splitter box is used for the wiring connection between optical fiber cables and optical fiber equipment.

[0004] The applicant has found that the prior art has at least the following technical problems:

[0005] Traditional optical cable splitter boxes often use a simple fixed docking method, which lacks effective buffering for optical fiber cables. When optical fiber cables are subjected to external tension, they are easily damaged due to excessive stretching, affecting the normal operation of the optical fiber cable communication system.

[0006] In addition, with the continuous development of fiber optic cable communication technology, the structure of optical transceiver modules has become increasingly compact, the complexity of products has continued to increase, and the number of optical fiber cables in the output module has also increased. However, the traditional docking method is cumbersome to install and has poor flexibility, which not only increases the difficulty of deployment, but also reduces the maintainability of the system, making it difficult to adapt to the increasingly compact and complex application scenarios in fiber optic cable communication systems.

[0037] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0038] like Figure 1-Figure 5 As shown, the present invention provides an optical fiber splitter and fiber splitter box for optical fiber cable communication protection, comprising an outer shell 1, a dynamic protection component 2 and a connection component;

[0039] The inlet side of the outer shell 1 is provided with a plurality of first clamping interfaces 103 for introducing a plurality of input optical fiber cables 7, and the outlet side thereof is provided with a second clamping interface 104 for connecting with an output optical fiber device;

[0040] The dynamic protection component 2 is rotatably disposed in the outer shell 1 and has a passage for the optical fiber cable to pass through; the dynamic protection component 2 is disposed in a one-to-one correspondence with the first clamping interface 103, and there is an accommodation space between the two for accommodating redundant optical fiber cables;

[0041] The connection component is used to connect the input optical fiber cable 7 output by the dynamic protection component 2 and to connect with the output optical fiber device through the second clamping interface 104 .

[0042] When the optical fiber cable is subjected to external tension, since a certain length of the optical fiber cable is reserved in the accommodating space, the dynamic protection component 2 can rotate with the tension of the optical fiber cable, and can provide a certain expansion and contraction margin for the optical fiber cable, so that the optical fiber cable will not be immediately straightened or tightened when subjected to tension, thereby reducing the risk of damage to the optical fiber cable due to excessive stretching.

[0043] The function of the connection component is to connect the input optical fiber cable 7 output by the dynamic protection component 2 and connect it to the output optical fiber device through the second clamping interface 104 to ensure the continuity and stability of the optical fiber signal during transmission.

[0044] As an optional implementation, Figure 1 , Figure 2 As shown, the outer shell 1 includes an outer lower shell 101 and an outer upper cover 102, which are detachably connected to jointly enclose a first accommodating cavity; a plurality of first clamping interfaces 103 are provided on the inlet side of the outer lower shell 101, and a second clamping interface 104 is provided on the outlet side.

[0045] Furthermore, a plurality of first wire entry openings are provided on the entrance side of the outer lower shell 101, and the first clamping interface 103 is sealedly connected to the first wire entry openings. The first clamping interface 103 can firmly clamp and fix the input optical fiber cable 7 to prevent the input optical fiber cable 7 from loosening.

[0046] The outlet side of the outer lower shell 101 is provided with a plurality of first outlet openings, and the second clamping interface 104 is sealed and connected to the first outlet openings. The second clamping interface 104 can firmly clamp and fix the wiring 8 of the output optical fiber device to prevent the wiring 8 from loosening.

[0047] It should be noted that the first clamping interface 103 and the second clamping interface 104 adopt the existing technology, which will not be described in detail here.

[0048] As an optional implementation, Figure 4 As shown, an annular sealing mounting seat 105 is provided on the outer lower shell 101, and a sealing ring 106 is provided on the sealing mounting seat 105. When the outer lower shell 101 and the outer upper cover 102 are closed, the sealing ring 106 forms a sealed connection between the two.

[0049] Furthermore, the outer lower shell 101 is connected to the outer upper cover 102 via a hinge assembly to achieve opening and closing of the two.

[0050] When the outer lower shell 101 and the outer upper cover 102 are buckled together, the outer upper cover 102 squeezes the sealing ring 106 so that the sealing ring 106 can fit tightly on the contact surface between the outer lower shell 101 and the outer upper cover 102, forming an effective sealing connection, maintaining the stability of the internal environment of the first accommodating cavity, and reducing the impact of the external environment on the input optical fiber cable 7.

[0051] As an optional implementation, Figure 4 , Figure 5 As shown, the dynamic protection component 2 includes an upper pressure plate 201, a rotating member 202 and a lower pressure plate 203, and the lower pressure plate 203 is connected to the outer lower shell 101 through the rotating member 202; the upper pressure plate 201 and the lower pressure plate 203 are detachably connected by bolts; the opposite surfaces of the upper pressure plate 201 and the lower pressure plate 203 are respectively provided with grooves, and a rubber pad layer is provided, which together enclose a channel for the input optical fiber cable 7 to pass through.

[0052] Furthermore, the bolt is a handle bolt 204, which is used to facilitate daily maintenance and replacement, and to improve the stability of the connection between the input optical fiber cable 7, the upper pressing plate 201, and the lower pressing plate 203. The handle bolt 204 passes through the upper pressing plate 201 and the lower pressing plate 203 in sequence to firmly fix the input optical fiber cable 7 in the channel between the upper pressing plate 201 and the lower pressing plate 203.

[0053] The lower pressing plate 203 is connected to the bottom plate of the outer lower shell 101 through the rotating member 202, so that the dynamic protection component 2 can rotate flexibly under the action of external force.

[0054] The function of the rubber pad layer is to increase the friction between the input optical fiber cable 7, effectively preventing the input optical fiber cable 7 from loosening, and also avoiding unnecessary crushing losses to the input optical fiber cable 7 caused by the upper pressure plate 201 and the lower pressure plate 203.

[0055] As an optional implementation, the lower pressing plate 203 is connected to the inner wall of the outer shell 1 through a tension spring.

[0056] With this arrangement, when the input optical fiber cable 7 is subjected to external tension, the dynamic protection component 2 will rotate accordingly, driving the tension spring to stretch, thereby absorbing and dispersing part of the tension, and further enhancing the tensile strength of the input optical fiber cable 7. At the same time, the tension spring also has a certain reset function, and after the external tension disappears, the tension spring will reset, driving the dynamic protection component 2 to return to its initial state.

[0057] First, loosen the first clamping interface 103 so that the input optical fiber cable 7 can smoothly penetrate the first clamping interface 103 and extend into the accommodation space along the preset path. When the input optical fiber cable 7 in the accommodation space reaches the required reserved length, place it on the groove of the lower pressing plate 203, and dock and install the end of the input optical fiber cable 7 with the connector 4 of the connecting assembly. Then, buckle the upper pressing plate 201 on the lower pressing plate 203 to clamp the input optical fiber cable 7. The groove and the rubber pad layer between the upper pressing plate 201 and the lower pressing plate 203 can firmly fix the input optical fiber cable 7 while avoiding unnecessary damage to the input optical fiber cable 7. Then pass the handle bolt 204 through the upper pressing plate 201 and the lower pressing plate 203, tighten the handle bolt 204, and connect the two tightly together to fix the input optical fiber cable 7. Finally, tighten the first clamping interface 103.

[0058] As an optional implementation, Figure 4 , Figure 5 As shown, it also includes an inner shell 3, which is detachably connected to the outer shell 1. The connecting component is located in the inner shell 3 and is used to connect the input optical fiber cable 7 output by the dynamic protection component 2 and connect to the output optical fiber device through the second clamping interface 104.

[0059] The inner housing 3 is used to provide a sealed and neat storage environment for the input optical fiber cable 7 and the connection components, thereby improving the protection performance. The inner housing 3 is connected to the bottom plate of the outer housing 1 by bolts, and is easy to assemble and disassemble.

[0060] As an optional implementation, Figure 4 , Figure 5 As shown, the inner shell 3 includes an inner lower shell 301 and an inner upper cover 302, the inner lower shell 301 is screwed into the outer lower shell 101, and is detachably connected to the inner upper cover 302 to jointly enclose a second accommodating cavity; the connecting component includes a connector 4 and a socket 6, the connector 4 is embedded in the second wire entry opening of the inner lower shell 301, and the two are sealed and connected by a rubber pad 10; the connector 4 is used to dock the input optical fiber cable 7 output by the dynamic protection component 2, and is detachably connected to the socket 6; the socket 6 is embedded in the second wire outlet opening of the inner lower shell 301, and is connected to the output optical fiber device through the second clamping interface 104.

[0061] The connector 4 is embedded in the second wire entry opening of the inner lower housing 301, and the two are sealed by a rubber pad 10 to improve the stability and reliability of the connection between the connector 4 and the inner lower housing 301, and at the same time, prevent external contaminants from entering the second accommodating cavity through the gap between the two. The function of the connector 4 is to enable the input optical fiber cable 7 to be smoothly connected and remain stable.

[0062] There is also a certain space between the connector 4 and the dynamic protection component 2 , which can accommodate the redundant input optical fiber cable 7 .

[0063] The rubber pad 10 can extend to the entrance end of the connector 4 , and the input optical fiber cable 7 first passes through the rubber pad 10 and then enters the connector 4 , so as to limit and fix the input optical fiber cable 7 .

[0064] The socket 6 and the second outlet opening are also sealed to improve the stability and reliability of the connection between the socket 6 and the inner lower shell 301, and at the same time, prevent external contaminants from entering the second accommodating cavity through the gap between the two. The socket 6 is used to connect with the wiring 8 of the output optical fiber device to achieve the output of the optical fiber signal. After passing through the second clamping interface 104, the wiring 8 is docked with the socket 6.

[0065] The connector 4 is plug-connected with the socket 6, and the specific plug-connection structure adopts the direct contact plug-in matching structure in the prior art, which will not be described in detail here. This arrangement makes the assembly and disassembly of the two convenient and reduces the difficulty of installation.

[0066] As an optional implementation, Figure 4 , Figure 5 As shown, the connection assembly also includes a sleeve 5, and a snap-in groove is provided in the inner lower shell 301 for fixing the sleeve 5; one end of the sleeve 5 is detachably connected to the connector 4, and the other end is detachably connected to the socket 6.

[0067] Furthermore, a filler such as foam or rubber pad is provided between the sleeve 5 and the inner upper cover 302, so that when the inner lower shell 301 and the inner upper cover 302 are closed, the inner lower shell is tightly connected to the sleeve 5 through the filler, further improving the stability of the connection between the connector 4 and the inner lower shell 301. In addition, since the sleeve 5 is connected to the snap-fit ​​groove of the inner lower shell 301 by snap-fitting, the connector 4 is limited and fixed to prevent it from loosening or displacement.

[0068] One end of the sleeve 5 is fixedly connected to the connector 4 by means of bolts, and the other end is connected to the socket 6 by means of a snap assembly 9 .

[0069] As an optional implementation, Figure 4 , Figure 5As shown, a buckle assembly 9 is provided on the sleeve 5, and the buckle assembly 9 includes a rotating shaft 901, a clamping claw 902 and a clamping column 903. The clamping claw 902 is connected to the sleeve 5 through the rotating shaft 901, and a clamping column 903 adapted to the clamping claw 902 is provided on the socket 6.

[0070] The rotating shaft 901 is arranged on the outer wall of the sleeve 5. The claw 902 is rotatably connected with the rotating shaft 901, and the friction between the two is relatively large, so a certain force needs to be applied to drive the claw 902 to rotate around the rotating shaft 901, so as to prevent the claw 902 from rotating by itself when no external force is applied. The clamping part of the claw 902 is a bent structure.

[0071] By rotating the claw 902 so that its engaging portion engages with the engaging column 903 , radial displacement of the socket 6 is limited, thereby effectively preventing the socket 6 from being separated from the connector 4 , and maintaining stability and reliability of the connection between the two.

[0072] As an optional implementation, Figure 4 , Figure 5 As shown, the inner lower shell 301 and the inner upper cover 302 are connected by a locking assembly 303 .

[0073] Furthermore, one side of the inner lower shell 301 and the inner upper cover 302 are connected by a hinge assembly, and the other side is connected by a locking assembly 303.

[0074] This arrangement allows the inner upper cover 302 to be easily opened and closed, so as to facilitate the access, arrangement and maintenance of the input optical fiber cable 7 and the wiring 8, thereby improving the protection performance. It can also ensure that the inner lower shell 301 and the inner upper cover 302 always maintain a stable locking state when closed, thereby improving the stability and reliability of use.
