Description

Technical Field

[0001] The present application relates to the technical field of optical fiber connection, and in particular to a through-tube type optical fiber connection port. Background Art

[0002] Fiber optic connectors are used to connect fiber optic cables and devices in fiber optic communication systems. They usually include a connector for fixing the optical fiber and an optical interface module connected to the optical interface inside the device. In fiber optic communication systems, fiber optic connectors are not only responsible for connecting fiber optic cables to devices, but also bear important functions such as transmission and conversion of optical signals. Therefore, when selecting and using fiber optic connectors, it is necessary to consider multiple aspects such as performance, reliability, and cost.

[0003] In the related art, when an optical fiber is connected to a router, in order to effectively prevent the optical fiber from being damaged during daily use, the optical fiber is often buried in a wall or underground pipe, and then the optical fiber is pulled out of the pipe and connected to the router.

[0004] However, since the optical fiber itself is very thin, it is not convenient to transport it in a pipeline, and most optical fibers are made of glass or plastic. When transported in a pipeline, the optical fiber is exposed and easily damaged.

[0005] Therefore, there is an urgent need for a connection port that can facilitate the transportation of optical fibers in pipelines and can also quickly and effectively connect the optical fibers to corresponding equipment. Utility Model Content

[0006] The present application provides a through-tube type optical fiber connector, the purpose of which is to facilitate the transportation of optical fiber in a pipeline, while also being able to quickly and effectively connect the optical fiber to corresponding equipment.

[0007] The present application provides a tube-through optical fiber connector, which adopts the following technical solution:

[0008] A tube-through optical fiber connector, comprising a dust cover, an optical fiber conduit, a ferrule, a threading post and a threading hole;

[0009] The optical fiber conduit is inserted into the dust cover, the ferrule and the optical fiber conduit are fixedly connected, one end of the ferrule extends into the optical fiber conduit, and the other end of the ferrule extends out of the optical fiber conduit, the threading post is connected to one end of the dust cover close to the ferrule, and the threading post cover is arranged on the side of the ferrule, and the threading hole is integrally opened on the top of the threading post.

[0010] By adopting the above technical solution, during the specific assembly, the optical fiber conduit is first inserted into the dust cover, and then the threading column is connected to the end of the optical fiber conduit, and the ferrule is covered by the threading column.

[0011] When installing the optical fiber, insert the optical fiber into the dust cover from the end of the dust cover away from the ferrule, and extend it into the optical fiber conduit until the optical fiber is embedded in the ferrule. The optical fiber is stably fixed by the dust cover, optical fiber conduit and ferrule. When the optical fiber is fixed, pass the iron wire through the threading hole and put the optical fiber connector into the corresponding pipe. Then, the staff extends the iron wire from the other end of the pipe. After the iron wire is extended from the other end, it drives the optical fiber connector to extend out of the pipe together, thereby completing the laying of the optical fiber in the pipe.

[0012] This setting method uses a threading pole to complete the laying of optical fiber in the pipeline, which can effectively prevent the optical fiber from being damaged when being transported in the pipeline. At the same time, it can also improve the efficiency of optical fiber transportation in the pipeline.

[0013] Preferably, the end of the dust cover close to the ferrule is provided with an external thread, the inner side of the bottom of the threading post is provided with an internal thread, and the dust cover and the threading post are threadably matched.

[0014] The adoption of the technical solution facilitates the installation and removal of the threading column and the dust cover, making assembly more convenient.

[0015] Preferably, an auxiliary spring is provided around the circumference of the optical fiber conduit.

[0016] By adopting the above technical solution, the outer diameter of the auxiliary spring is larger than the inner diameter of the dust cover, that is, the auxiliary spring will not be inserted into the dust cover along with the optical fiber conduit. When the optical fiber conduit is inserted into the dust cover, the auxiliary spring is clamped between the end of the dust cover and the connector of the optical fiber conduit.

[0017] When the threading post is threaded onto the dust cover, the inner wall of the threading post will press the auxiliary spring to the end of the dust cover. When the threading post is removed from the dust cover, the auxiliary spring will push the threading post away from the dust cover during the process of recovering its deformation, thereby facilitating the installation and removal of the threading post and the dust cover, making it more convenient to use.

[0018] Preferably, it further comprises a connecting terminal and a free terminal, wherein the connecting terminal and the free terminal are connected by snapping, the free terminal is used to position the ferrule, and the free terminal is connected to a corresponding device through the connecting terminal;

[0019] The connecting terminal and the free terminal are both provided with fool-proof parts.

[0020] By adopting the above technical solution, the fool-proof part helps the staff to assemble the connecting terminal and the free terminal.

[0021] Preferably, the fool-proof portion includes punctuation marks, and the punctuation marks are sprayed on the outer walls of the connecting terminal and the free terminal.

[0022] By adopting the above technical solution, circular red punctuation marks are sprayed on the outer walls of the connecting terminal and the free terminal. When the staff assembles the free terminal and the connecting terminal, they must align the punctuation marks on the outer walls of the two before they can assemble them. Furthermore, when the staff assembles the connecting terminal and the free terminal, they do not need to repeatedly compare the connecting ports between the two, but only need to align the corresponding punctuation marks, which is very convenient.

[0023] Preferably, the fool-proof portion further includes rounded corners, and the ends where the connecting terminal and the free terminal are connected are both rounded.

[0024] By adopting the above technical solution, during assembly, it is necessary to align the chamfers on the two terminals, and the chamfering process can further help the staff to confirm the installation positions of the connecting terminals and the free terminals.

[0025] Preferably, an anti-slip portion is integrally engraved on the outer wall of the threading post.

[0026] By adopting the above technical solution, when the staff installs the threading post thread into the dust cover, the anti-slip part can effectively increase the friction between the staff and the threading post, thereby effectively preventing the threading post from slipping during the twisting process.

[0027] Preferably, the insert is made of ceramic material.

[0028] By adopting the above technical solutions, the ceramic ferrule has extremely high dimensional accuracy and surface finish, which can effectively ensure the stable and efficient transmission of optical signals. Due to its high hardness, high wear resistance, good corrosion resistance and insulation, the ceramic ferrule is widely used in various optical fiber communication systems and has become a key component to ensure the quality of optical signal transmission.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] 1. During the specific assembly, first insert the optical fiber conduit into the dust cover, then connect the threading column to the end of the optical fiber conduit, and cover the ferrule through the threading column.

[0031] When installing the optical fiber, insert the optical fiber into the dust cover from the end of the dust cover away from the ferrule, and extend it into the optical fiber conduit until the optical fiber is embedded in the ferrule. The optical fiber is stably fixed by the dust cover, optical fiber conduit and ferrule. When the optical fiber is fixed, pass the iron wire through the threading hole and put the optical fiber connector into the corresponding pipe. Then, the staff extends the iron wire from the other end of the pipe. After the iron wire is extended from the other end, it drives the optical fiber connector to extend out of the pipe together, thereby completing the laying of the optical fiber in the pipe.

[0032] This arrangement uses a threading pole to complete the laying of optical fibers in the pipeline, which can effectively prevent the optical fibers from being damaged during transportation in the pipeline, and at the same time, can also improve the efficiency of optical fiber transportation in the pipeline;

[0033] 2. The outer diameter of the auxiliary spring should be larger than the inner diameter of the dust cover, that is, the auxiliary spring will not be inserted into the dust cover along with the optical fiber catheter. When the optical fiber catheter is inserted into the dust cover, the auxiliary spring is clamped between the end of the dust cover and the connector of the optical fiber catheter.

[0034] When the threading post is threaded onto the dust cover, the inner wall of the threading post will press the auxiliary spring to the end of the dust cover. When the threading post is removed from the dust cover, the auxiliary spring will push the threading post away from the dust cover during the process of restoring its deformation, which is conducive to enhancing the convenience of installation and removal between the threading post and the dust cover, making it more convenient to use.

[0035] 3. When the staff installs the threading post thread into the dust cover, the anti-slip part can effectively increase the friction between the staff and the threading post, thereby effectively preventing the threading post from slipping during the twisting process.

[0039] The following is combined with Figure 1 -Attached Figure 2 , further details of this application are given.

[0040] Example:

[0041] The present application embodiment discloses a tube-through optical fiber connector. Figure 1 , including a dust cover 1, an optical fiber conduit 2, a ferrule 3, a threading post 4 and a threading hole 5. The dust cover 1 is hollow inside, and both the upper and lower ends are open; the optical fiber conduit 2 is columnar, hollow inside, and one end is open, the ferrule 3 extends into the optical fiber conduit 2 from the end of the optical fiber conduit 2 away from the opening, and is integrally injection-molded with the optical fiber conduit 2, and the top of the ferrule 3 extends out of the optical fiber conduit 2; the threading post 4 is also hollow inside, and the threading hole 5 is integrally opened at the top of the threading post 4.

[0042] In this embodiment, the threading post 4 is made of metal to effectively ensure the structural strength of the threading post 4; the ferrule 3 is made of ceramic material. The ceramic ferrule 3 has extremely high dimensional accuracy and surface finish, which can effectively ensure the stable and efficient transmission of optical signals. In addition, due to its high hardness, high wear resistance, good corrosion resistance and insulation, the ceramic ferrule 3 is widely used in various optical fiber communication systems and has become a key component to ensure the quality of optical signal transmission.

[0043] Specifically, the outer diameter of the optical fiber conduit 2 is matched with the inner diameter of the dust cover 1, that is, the optical fiber conduit 2 can be inserted into the dust cover 1, and when the optical fiber conduit 2 is inserted into the dust cover 1, the outer wall of the optical fiber conduit 2 is in a tightly attached state with the inner wall of the dust cover 1. At the same time, the end of the optical fiber conduit 2 is integrally formed with a connector 11. After the optical fiber conduit 2 is fully inserted into the dust cover 1, the opening of the dust cover 1 is sealed by the connector 11, thereby effectively preventing external dust from entering the dust cover 1.

[0044] During specific assembly, the optical fiber conduit 2 is first inserted into the dust cover 1 , and then the threading post 4 is connected to the end of the optical fiber conduit 2 , and the ferrule 3 is covered by the threading post 4 .

[0045] Specifically, when installing the optical fiber, the optical fiber is inserted into the dust cover 1 from the end of the dust cover 1 away from the ferrule 3, and extended into the optical fiber conduit 2 until the optical fiber is embedded in the ferrule 3. The optical fiber is stably fixed by the dust cover 1, the optical fiber conduit 2 and the ferrule 3. After the optical fiber is fixed, the iron wire is passed through the threading hole 5, and the optical fiber connector is placed in the corresponding pipe. Then, the staff extends the iron wire from the other end of the pipe. After the iron wire is extended from the other end, it drives the optical fiber connector to extend out of the pipe together, thereby completing the laying of the optical fiber in the pipe.

[0046] This arrangement uses the threading pole 4 to complete the laying of optical fibers in the pipeline, which can effectively prevent the optical fibers from being damaged when being transported in the pipeline, and at the same time, can also improve the efficiency of transporting the optical fibers in the pipeline.

[0047] Reference Figure 1 The optical fiber connection port also includes a connection terminal 7 and a free terminal 8. After the optical fiber is pulled out of the pipe through the threading post 4, the threading post 4 is removed from the dust cover 1, and the ferrule 3 is inserted into the free terminal 8, and the ferrule 3 and the optical fiber in the ferrule 3 are fixed through the free terminal 8. Then the free terminal 8 is clamped onto the connection terminal 7 and connected to the corresponding device through the connection terminal 7.

[0048] In this embodiment, the end of the dust cover 1 close to the insert 3 is provided with an external thread, and the inner side of the bottom of the threading post 4 is provided with an internal thread. The threads of the dust cover 1 and the threading post 4 are matched, which facilitates the installation and removal between the threading post 4 and the dust cover 1 and facilitates assembly.

[0049] Further, refer to Figure 1 The outer wall of the threading post 4 is integrally engraved with an anti-slip portion 10. When the staff thread the threading post 4 to the dust cover 1, the anti-slip portion 10 can effectively increase the friction between the staff and the threading post 4, thereby effectively preventing the threading post 4 from slipping during the twisting process.

[0050] Further, refer to Figure 1 An auxiliary spring 6 is provided on the circumferential side of the optical fiber conduit 2, and the outer diameter of the auxiliary spring 6 is larger than the inner diameter of the dust cover 1, that is, the auxiliary spring 6 will not be inserted into the dust cover 1 along with the optical fiber conduit 2. When the optical fiber conduit 2 is inserted into the dust cover 1, the auxiliary spring 6 is clamped between the end of the dust cover 1 and the connector 11 of the optical fiber conduit 2.

[0051] When the threading post 4 is threadedly installed on the dust cover 1, the inner wall of the threading post 4 will press the auxiliary spring 6 to the end of the dust cover 1. When the threading post 4 is removed from the dust cover 1, the auxiliary spring 6 will push the threading post 4 away from the dust cover 1 during the process of recovering its deformation, which is conducive to enhancing the convenience of installation and removal between the threading post 4 and the dust cover 1, making it more convenient to use.

[0052] Further, refer to Figure 1 and Figure 2 Both the connecting terminal 7 and the free terminal 8 are provided with a fool-proof portion 9 , and the addition of the fool-proof portion 9 helps the staff to assemble the connecting terminal 7 and the free terminal 8 .

[0053] Specifically, refer to Figure 1 and Figure 2 The fool-proofing portion 9 includes a punctuation mark 91. By spraying a circular red punctuation mark 91 on the outer wall of the connecting terminal 7 and the free terminal 8, when the staff assembles the free terminal 8 and the connecting terminal 7, they must align the punctuation marks 91 on the outer walls of the two before they can assemble them. Therefore, when the staff assembles the connecting terminal 7 and the free terminal 8, they do not need to repeatedly compare the connection ports between the two, but only need to align the corresponding punctuation marks 91, which is very convenient.

[0054] At the same time, refer to Figure 1 and Figure 2 The anti-mock portion 9 also includes a chamfer 92. The ends where the connecting terminal 7 and the free terminal 8 are connected are both chamfered 92. Specifically, during assembly, the chamfers 92 on the two need to be aligned. The chamfer 92 can further help the staff confirm the installation positions of the connecting terminal 7 and the free terminal 8.

[0055] The implementation principle of a tube-through optical fiber connector in the embodiment of the present application is:

[0056] During specific assembly, the optical fiber conduit 2 is first inserted into the dust cover 1 , and then the threading post 4 is connected to the end of the optical fiber conduit 2 , and the ferrule 3 is covered by the threading post 4 .

[0057] Specifically, when installing the optical fiber, the optical fiber is inserted into the dust cover 1 from the end of the dust cover 1 away from the ferrule 3, and extended into the optical fiber conduit 2 until the optical fiber is embedded in the ferrule 3. The optical fiber is stably fixed by the dust cover 1, the optical fiber conduit 2 and the ferrule 3. After the optical fiber is fixed, the iron wire is passed through the threading hole 5, and the optical fiber connector is placed in the corresponding pipe. Then, the staff extends the iron wire from the other end of the pipe. After the iron wire is extended from the other end, it drives the optical fiber connector to extend out of the pipe together, thereby completing the laying of the optical fiber in the pipe.

[0058] This arrangement uses the threading pole 4 to complete the laying of optical fibers in the pipeline, which can effectively prevent the optical fibers from being damaged when being transported in the pipeline, and at the same time, can also improve the efficiency of transporting the optical fibers in the pipeline.

[0059] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
