Technical Field

[0001] This invention relates to the field of optical fiber communication technology, and in particular to a reflection device and an optical fiber connector box. Background Technology

[0002] With the development of broadband technology, Passive Optical Network (PON) technology is one of the most widely used Fiber to the Home (FTTH) technologies. As the use of PON networks becomes more frequent, technologies for link mapping visualization, port usage monitoring, and fault detection are becoming increasingly important.

[0003] In passive networks, the network topology is complex, and it is currently impossible to intelligently acquire information about each node. This results in operators or central offices being unable to obtain node and port usage information, or requiring manual recording to determine node and port usage, leading to significant resource waste. How to intelligently and accurately record the usage of each node and network health issues has become an urgent problem to be solved.

[0004] Therefore, it is necessary to design a new reflection device and fiber optic connector to overcome the above problems. Summary of the Invention

[0011] In some embodiments, the reflecting device further includes a core, the light reflector is fixed inside the core, and ceramic sleeves are respectively fitted at opposite ends of the core; the sliding member includes two sliders, which are clamped between the core and the ceramic sleeves.

[0012] In some embodiments, each of the sliders is provided with a mounting protrusion and a mounting hole, and the mounting protrusions on the two sliders are mounted into the corresponding mounting holes by an interference fit.

[0013] In some embodiments, the slider has a first limiting step inside, and the first limiting steps of the two sliders are respectively clamped on opposite sides of the insert; the slider also has a second limiting step outside, the elastic element is sleeved on one of the sliders, and one end of the elastic element abuts against the second limiting step.

[0014] In some embodiments, the reflecting device includes a housing, in which the light reflector and the driving assembly are encapsulated; a positioning element is also installed within the housing, the positioning element having a hook for securing with a connector; the positioning element has a sliding cavity, in which the driving assembly and the light reflector are at least partially confined, and the driving assembly and the light reflector are slidable within the sliding cavity.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] This invention provides a reflection device and an optical fiber connector box, which can solve the problem of how to intelligently and accurately record the usage of each node and the health of the network in related technologies.

[0037] See Figure 1 and Figure 2 As shown, a reflection device provided in an embodiment of the present invention may include: a light reflector 2 capable of reflecting light waves; and a driving component 3 connected to the light reflector 2. This connection can be direct or indirect. The driving component 3 is configured to disconnect the light reflector 2 from the connector at the first end when the first end of the light reflector 2 is connected to a connector and the second end is not connected. That is, the driving component 3 can provide driving force to disconnect the light reflector 2 from the connector at its first end. When both the first and second ends of the light reflector 2 are connected to connectors, the driving component 3 can connect the light reflector 2 to the connectors at both ends. In other words, after the connector at the second end is connected, the driving component 3 can drive the light reflector 2 to contact the connector at the first end, thereby connecting the light reflector 2 to the connectors at both ends. When the connector at the second end is connected, the driving component 3 can be driven directly through the connector at the second end, thereby causing the driving component 3 to move the light reflector 2; alternatively, other power can be used to drive the driving component 3 to move the light reflector 2.

[0038] In this embodiment, the driving component 3 can disconnect the optical reflector 2 from the connector at the first end when the second end of the optical reflector 2 is not connected to the connector, and connect the connectors at both ends of the optical reflector 2 when both ends are connected to the connector. In the state where the connector at the second end is not connected, light can be transmitted and the reflection is weak. When the connector at the second end is connected, both ends of the optical reflector 2 are connected. At this time, waves of a specific wavelength can be reflected in large quantities under the action of the optical reflector 2, while waves of non-specific wavelengths are transmitted through the optical reflector 2. This means that the connector at the second end can reflect different light waves through the optical reflector 2 in the connected and unconnected states, thereby realizing the detection of the optical fiber link. Therefore, it can intelligently and accurately record the usage status of each node and the network health.

[0039] In some embodiments, see Figure 1 and Figure 2 As shown, the reflecting device may further include a housing 1, with the light reflector 2 and driving component 3 encapsulated within the housing 1. The housing 1 may be a one-piece structure, or it may include male and female terminals that are assembled together; that is, the male and female terminals are not integrally formed, and the light reflector 2 and driving component 3 may be encapsulated within either the male or female terminal. In this embodiment, the reflecting device may be an SC adapter, an LC adapter, a waterproof adapter, or a male-female adapter, and can be designed according to actual usage requirements. Of course, in other embodiments, the reflecting device may also be a structure that does not include the housing 1.

[0040] Preferably, the housing 1 may have an inner interface 11 and an outer interface 12, wherein the inner interface 11 and the outer interface 12 are respectively disposed at opposite ends of the housing 1, and the inner interface 11 and the outer interface 12 are respectively used to insert an inner connector 200 and an outer connector 100, wherein the inner connector 200 is the connector located at the first end of the light reflector 2, and the outer connector 100 is the connector located at the second end of the light reflector 2; and the housing 1 has a mounting cavity 13, which connects the inner interface 11 and the outer interface 12; the light reflector 2 and the driving assembly 3 are installed in the mounting cavity 13. The driving assembly 3 can disconnect the light reflector 2 from the other connector when the outer interface 12 is not connected to the outer connector 100, and connect the connectors at both ends of the housing 1 to the light reflector 2 when the outer connector 100 is connected.

[0041] See Figure 4As shown, in some embodiments, the light reflector 2 may include a fiber core 21 on which a Bragg grating 22 is disposed. The Bragg gratings 22 may be spaced apart on the fiber core 21. Preferably, a cladding 23 may be fitted over the fiber core 21 and the Bragg gratings 22. In this embodiment, the reflection of waves of a specific wavelength can be achieved by distributing the Bragg grating 22 on the fiber core 21. Of course, in other embodiments, a reflective film can also be deposited on the end face of the fiber core 21 to achieve light wave reflection.

[0042] In some embodiments, see Figure 2 and Figure 3 As shown, the reflecting device further includes a retainer 4, in which the light reflector 2 is fixed. The driving assembly 3 drives the light reflector 2 through the retainer 4. That is, in this embodiment, the light reflector 2 is fixed by the retainer 4, connecting it to the driving assembly 3. Preferably, the retainer 4 is a ceramic retainer. Fixing the light reflector 2 with the retainer 4 protects it and reduces the risk of damage. Of course, in other embodiments, the light reflector 2 can be directly fixed to the driving assembly 3.

[0043] Furthermore, in some optional embodiments, see [link to documentation]. Figure 1 and Figure 2 As shown, the driving component 3 may include a slider 31 and an elastic element 32. The elastic element 32 is disposed on one side of the slider 31. In this embodiment, it is preferably disposed on the side closer to the inner interface 11. The elastic element 32 is configured to drive the slider 31 to move toward the side away from the elastic element 32. The light reflector 2 is mounted on the slider 31. In this embodiment, the elastic element 32 may be a spring or other elastic component. Since the elastic element 32 is disposed on the side of the slider 31 closer to the inner interface 11, under the action of the elastic force of the elastic element 32, the slider 31 can be driven to move toward the side away from the inner interface 11 (that is, the side away from the elastic element 32), so that the slider 31 drives the light reflector 2 to move toward the side away from the inner interface 11, thereby disengaging the light reflector 2 from the inner connector 200. When the slider 31 moves toward the side closer to the inner interface 11, the slider 31 will push the elastic element 32 to compress. Therefore, in this embodiment, by providing the elastic element 32, the elastic element 32 can automatically drive the light reflector 2 to disconnect from the inner connector 200 when the outer connector 100 is not engaged. Of course, in other embodiments, other linear drive components 3 can also be provided to drive the light reflector 2 to move.

[0044] In some embodiments, see Figure 2 and Figure 3As shown, the reflecting device further includes a core 4, the light reflector 2 is fixed inside the core 4, and ceramic sleeves 5 are respectively fitted at opposite ends of the core 4, that is, each end of the core 4 is provided with a ceramic sleeve 5; the sliding member 31 may include two sliders 311, that is, in this embodiment, the sliding member 31 is divided into two separate parts, and the two separate parts can be assembled into a whole, with the two sliders 311 clamping the core 4 and the ceramic sleeve 5. By setting two sliders 311 to clamp and fix the core 4 and the ceramic sleeve 5, it is easier to assemble and disassemble the sliding member 31, the core 4, and the ceramic sleeve 5. Of course, in other embodiments, the sliding member 31 can also be a one-piece structure.

[0045] See Figure 1 and Figure 5 As shown, in some optional embodiments, each slider 311 may be provided with a mounting protrusion and a mounting hole. The mounting protrusions on two sliders 311 are installed into the corresponding mounting holes by an interference fit. That is, the mounting protrusion on one slider 311 is inserted into the mounting hole of the other slider 311, and at the same time, the mounting protrusion of the other slider 311 is inserted into the mounting hole of one slider 311, so that the two sliders 311 cooperate and are fixed together. In this embodiment, the two sliders 311 can be fixed using their own structure, without the need to add additional fasteners to fix the two sliders 311, making the adapter structure simpler and smaller in size. Of course, in other embodiments, other fixing structures can also be used to fix the two sliders 311, such as magnetic attraction or adhesive, or a separate fastener can be added to constrain and fix the two sliders 311.

[0046] See Figure 2As shown, preferably, the slider 311 may be provided with a first limiting step 312. The first limiting steps 312 of the two sliders 311 are respectively clamped on the opposite sides of the insert 4, so that the first limiting steps 312 limit and fix the insert 4. The insert 4 may include a body 41 and a metal handle 42 disposed on the body 41. The metal handle 42 protrudes from the surface of the body 41. The light reflector 2 is fixed inside the body 41, and the two first limiting steps 312 can be clamped on the protruding metal handle 42. The ceramic sleeve 5 can be sleeved on the opposite ends of the body 41. The slider 311 may also be provided with a second limiting step 313. The slider 311 can be limited to the adapter body 41 by the second limiting step 313. The elastic member 32 is sleeved on one of the sliders 311, and one end of the elastic member 32 abuts against the second limiting step 313. In this embodiment, the elastic element 32 is sleeved on the slider 311. This arrangement allows the slider 311 to guide the elastic element 32, preventing it from tilting. In other embodiments, the elastic element 32 may be located entirely on one side of the slider 311, or the sliding member 31, with one end of the spring abutting against the end of the slider 311, or the sliding member 31. In this case, the elastic element 32 is not sleeved on the slider 311, or the sliding member 31.

[0047] Furthermore, the light reflector 2 can be fixed to the body 41 with glue, or it can be fixed in other ways.

[0048] See Figure 5 and Figure 6 As shown, in some embodiments, a positioning member 6 may also be installed inside the housing 1. The positioning member 6 has a hook 61 for fixing to the connector; the positioning member 6 has a sliding cavity, and the driving component 3 and the light reflector 2 are at least partially confined within the sliding cavity, and the driving component 3 and the light reflector 2 can slide within the sliding cavity. That is, in this embodiment, the driving component 3 and the light reflector 2 are positioned and installed inside the housing 1 by the positioning member 6, and the positioning member 6 can limit the driving component 3 and the light reflector 2, restricting their sliding distance, ensuring that the light reflector 2 can be driven to disconnect from the inner connector 200 when the outer connector 100 is not inserted, and can be connected to the inner connector 200 after the outer connector 100 is inserted. By setting the positioning member 6, the entire adapter can also be easily assembled. Of course, in other embodiments, the driving component 3 and the light reflector 2 can also be directly installed inside the housing 1.

[0049] Furthermore, in some optional embodiments, the housing 1 may also have a through slot, which penetrates one side of the housing 1 and communicates with the mounting cavity 13. In this embodiment, the through slot is located at the top of the housing 1. The light reflector 2 and the driving assembly 3 are installed into the mounting cavity 13 through the through slot, and a cover 7 is correspondingly provided at the through slot. Simultaneously, the positioning member 6 can also be installed into the housing 1 through the through slot. In this embodiment, by providing a through slot on the housing 1, the installation and disassembly of the internal components of the housing 1 can be facilitated. Furthermore, the cover 7 can seal the interior of the housing 1.

[0050] Preferably, both the inner interface 11 and the outer interface 12 of the housing 1 can be provided with dust caps 8, and the housing 1 can also be provided with fixing hooks 9, which can be used to fix the housing 1 to the box 300.

[0051] The assembly sequence of the reflective device provided in this embodiment of the invention can be as follows: First, assemble the positioning component 6 into the housing 1 from top to bottom. Then, install the ceramic sleeve 5 into the two sliders 311 respectively. After aligning the insert 4 with the symmetrically designed sliders 311, clamp the ceramic sleeve 5. The ceramic sleeve 5 moves through the metal handle 42 of the insert 4 and the sliders 311. Install the spring on the assembled components (i.e., sliders 311, insert 4, and ceramic sleeve 5), and then install it into the positioning component 6 in the housing 1 so that the spring is located on the side close to the inner interface 11. Then, cover the cover 7 and dust cap 8 to complete the assembly.

[0052] See Figure 5 and Figure 6 As shown, the principle of this embodiment of the invention is as follows: When only the inner interface 11 of the housing 1 is connected to the inner connector 200, and the outer interface 12 is not connected to the outer connector 100, the slider 311 will disconnect the ferrule 4 from the inner connector 200 under the action of the spring, making the disconnection point easy to identify on the monitoring equipment; when the outer connector 100 is inserted into the outer interface 12, the positioning member 6 will engage with the outer connector 100 and push the slider 311 to the reference optical surface position under the force of the outer connector 100. At this time, the slider 311 drives the light reflector 2 to move, so that one end of the light reflector 2 is connected to the inner connector 200 and the other end is connected to the outer connector 100, and the link is normally connected. This invention realizes dynamic identification of insertion and removal in the optical footprint, and has good operation convenience. It can use physical methods to solve the inaccurate system statistics caused by incorrect installation; and a Bragg grating 22 is arranged in the adapter. This adapter can be used alone or in combination with a splitter.

[0053] See Figures 7 to 9As shown, this embodiment of the invention also provides an optical fiber connector box, which may include a box body 300. The box body 300 is equipped with a reflective device, which may include: a light reflector 2; and a driving component 3. The driving component 3 is connected to the light reflector 2, and the driving component 3 is configured to drive the light reflector 2 to disconnect from the connector at the first end when the first end of the light reflector 2 is connected to a connector and the second end is not connected to a connector; and to drive the light reflector 2 to connect to the connectors at both ends when both the first end and the second end of the light reflector 2 are connected to connectors.

[0054] The reflective device provided in this embodiment can adopt any of the structural forms in the above embodiments and can achieve the corresponding effects, which will not be elaborated here.

[0055] In some embodiments, the housing 1 is at least partially located on the outside of the box 300. That is, the adapter is rear-mounted. The housing 1 can be completely disposed outside the box 300, or a portion of the housing 1 can be disposed inside the box 300 and another portion outside. In this embodiment, disposing the housing 1 on the outside of the box 300 supports existing network retrofitting and smooth upgrades, and supports dynamic plug-in / plug-out identification. Furthermore, the housing 1 can have various structural forms; it can be a male-female type, allowing for physical disassembly; or the housing 1 can be integrally fixed to the rear of the box 300.

[0056] In this embodiment, the reflective device can be an SC adapter, an LC adapter, a waterproof adapter, or a male-female adapter, and can be designed according to actual usage requirements. Of course, in other embodiments, the reflective device may also be a structure that does not include the housing 1. Figure 7 and Figure 8 The image shows the male and female adapters installed at the rear of the box 300. Figure 9 The diagram shows the integrated adapter structure installed at the rear of the box 300.
