Description

Technical Field

[0001] This utility model relates to optical devices, and in particular to a fiber optic cable wired transmission line splitter, belonging to the technical field of fiber optic cable splitters. Background Technology

[0002] A splitter used in optical fiber cables is an optical device that distributes optical signals to multiple receivers. A splitter can divide a single optical signal into multiple identical optical signals, allowing multiple receivers to receive the same signal simultaneously, thereby enabling distributed transmission in optical fiber networks. During use, optical fiber cables need to be branched into multiple optical cables using splitters to branch the trunk line.

[0003] A search of relevant technologies revealed that, in order to address the problems of existing optical cable splitters, such as inconvenience in disassembling and splitting multi-core optical cables, and susceptibility to moisture buildup due to weather conditions, a multi-core optical cable splitter disclosed in publication number CN216285886U was proposed. This multi-core optical cable splitter, through the inclusion of a telescopic rod, a U-shaped bracket, a movable block, a sliding rod, a second spring, a locking rod, and a locking slot, utilizes a telescopic rod to move the U-shaped bracket downwards. The U-shaped bracket then presses against the movable block, which in turn presses against the second spring via the sliding rod. This causes the movable block to disengage the locking rod from the locking slot, facilitating the removal of the protective cover. This design facilitates the disassembly and installation of the protective cover and promotes splitting operations.

[0004] However, existing junction boxes cannot easily limit the branch optical cables, which can cause the optical cables to separate and fall off due to external pulling during use. This results in poor stability during use and affects the use of the cable. In addition, because the connector is in a fixed state, it is inconvenient to connect the inner and internal optical cables during the connection of multiple optical cables.

[0005] Therefore, a fiber optic wired transmission line splitter is proposed. Utility Model Content

[0006] In view of this, the present invention provides an optical cable wired transmission line splitter to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0007] The technical solution of this utility model is implemented as follows: a fiber optic cable wired transmission line splitter includes: a splitter box, a cover plate, and a limiting buckle. The top of the splitter box is movably mounted with a cover plate, and a limiting buckle is fixedly mounted on the outer side of the cover plate. A pigtail connector is fixedly mounted inside the splitter box. A mounting bracket is fixedly mounted at the front end of the pigtail connector. An external connector is rotatably mounted inside the mounting bracket. The external connector and the pigtail connector are movably connected via an external wiring connection. An external wiring connection extending out of the splitter box is mated to the front end of the external connector. A threaded sleeve is threaded onto the front end of the pigtail connector. A mounting plate is movably connected to one side of the threaded sleeve. A rack is fixedly mounted on one side of the mounting plate. A gear extending out of the mounting bracket is fixedly mounted on the top of the external connector. A fixing frame is fixedly mounted at the front end of the splitter box. A movable plate is movably mounted on the inner side of the fixing frame. A limiting clamp that mates with the external wiring connection is fixedly mounted on the inner side of the movable plate. An inclined plate is fixedly mounted on the outer side of the movable plate. A pressing wheel corresponding to the inclined plate is slidably mounted inside the fixing frame.

[0008] More preferably, a mating sleeve corresponding to the limiting buckle is fixedly installed on the outside of the distribution box, and the mating sleeve and the mating hole are limited and fixed by a fixing knob, and the limiting buckle is provided with a mating hole corresponding to the fixing knob.

[0009] More preferably, the rear end of the pigtail connector is fixedly installed with an optical cable extending out of the junction box, and a main conduit is provided on one side of the junction box.

[0010] More preferably, a sealing gasket corresponding to the cover plate is fixedly installed on the top of the junction box, and the sealing gasket is provided with a movable groove for the limit buckle to move.

[0011] More preferably, the pigtail connector and the threaded sleeve are connected by a helical rod threaded together, and a rotating disk is fixedly installed at one end of the helical rod.

[0012] More preferably, the rack and gear mesh with each other, and the external wiring passes through the inside of the fixing frame and is located inside the limiting clamp.

[0013] More preferably, the extrusion wheel and the fixed frame are slidably mounted via a groove, and the movable plate is movably connected to the inner side of the fixed frame via a spring.

[0014] More preferably, a telescopic rod is fixedly installed on the outer side of the fixing frame, a base plate is fixedly installed inside the fixing frame, a top rod extending to the bottom of the extrusion wheel is fixedly installed on the top of the base plate, and the base plate and the telescopic rod are fixedly connected.

[0015] The present invention has the following advantages due to the adoption of the above technical solution:

[0016] I. This utility model, through the cooperation of a limiting clamp, a pressing wheel, an inclined plate, a sliding groove, and a top rod, allows the external wiring to pass through the inner side of the limiting clamp. The extension and retraction of the telescopic rod lifts the base plate, enabling the top rod to slide along the inside of the fixed frame during the movement of the base plate. This causes the fixed frame to press against the pressing wheel, which in turn slides along the inside of the sliding groove. Consequently, the pressing wheel slides along the inclined surface of the inclined plate, pushing the movable plate inward. This causes the spring to deform, bringing the limiting clamps closer together and thus limiting the external wiring inside the limiting clamp. This makes limiting the external wiring more convenient and prevents the optical cable from separating and falling off due to external pulling.

[0017] II. This utility model, through the mutual cooperation of an external connector, mounting bracket, gear, rack and pinion, and spiral rod, allows the spiral rod to rotate synchronously by rotating the rotating disk. This causes the threaded sleeve on the outside of the spiral rod to move along the thread direction on the outside of the spiral rod, thereby driving the mounting plate to move. This allows the rack and gear to mesh with each other, and the external connector to rotate inside the mounting bracket. This allows for better space avoidance during the installation of the external connector and the pigtail connector, making the installation process more convenient and faster.

[0018] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

Detailed Implementation

[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] like Figures 1-5 As shown, this utility model embodiment provides an optical cable wired transmission line splitter, including: a splitter box 1, a cover plate 2, and a limiting buckle 3. The cover plate 2 is movably installed on the top of the splitter box 1, and the limiting buckle 3 is fixedly installed on the outer side of the cover plate 2. A pigtail connector 8 is fixedly installed inside the splitter box 1. A mounting bracket 12 is fixedly installed at the front end of the pigtail connector 8. An external connector 18 is rotatably installed inside the mounting bracket 12. The external connector 18 and the pigtail connector 8 are movably installed through an external wiring 11. An external wiring 11 extending out of the splitter box 1 is mated to the front end of the external connector 18. A threaded sleeve 15 is threadedly installed at the front end of the pigtail connector 8. A mounting plate 16 is movably connected to one side of the threaded sleeve 15. A rack 17 is fixedly installed on one side of the 16. A gear 19 extending from the mounting bracket 12 is fixedly installed on the top of the external connector 18. A fixing bracket 20 is fixedly installed at the front end of the junction box 1. A movable plate 22 is movably installed on the inner side of the fixing bracket 20. A limiting clamp 23 that cooperates with the external wiring 11 is fixedly installed on the inner side of the movable plate 22. An inclined plate 24 is fixedly installed on the outer side of the movable plate 22. A pressing wheel 25 corresponding to the inclined plate 24 is slidably installed inside the fixing bracket 20. A telescopic rod 21 is fixedly installed on the outer side of the fixing bracket 20. A base plate 27 is fixedly installed inside the fixing bracket 20. A top rod 28 extending to the bottom of the pressing wheel 25 is fixedly installed on the top of the base plate 27. The base plate 27 and the telescopic rod 21 are fixedly connected.

[0029] The pressing wheel 25 slides along the inclined surface of the inclined plate 24, thereby pushing the movable plate 22 to move inward, causing the spring 29 to deform, causing the limiting clamps 23 to move closer to each other, thereby limiting the external wiring 11 inside the limiting clamps 23. This makes it more convenient to limit the external wiring 11 and prevents the optical cable from separating and falling off due to external pulling.

[0030] Reference Figure 4 and Figure 5 A mating sleeve 5 corresponding to the limit buckle 3 is fixedly installed on the outside of the distribution box 1. The mating sleeve 5 and the mating hole 4 are fixed by a fixing knob 6. The limit buckle 3 is provided with a mating hole 4 corresponding to the fixing knob 6. An optical cable extending out of the distribution box 1 is fixedly installed at the rear end of the pigtail connector 8. A main line pipe 7 is provided on one side of the distribution box 1.

[0031] The extrusion roller 25 slides along the inclined surface of the inclined plate 24, thereby pushing the movable plate 22 to move inward, causing the spring 29 to deform, which causes the limiting clamps 23 to move closer to each other, thereby limiting the external wiring 11 inside the limiting clamps 23, making it more convenient to limit the external wiring 11.

[0032] Reference Figures 1-3 The top of the junction box 1 is fixedly installed with a sealing gasket 9 corresponding to the cover plate 2. The sealing gasket 9 is provided with a movable groove 10 for the limit buckle 3 to move. The pigtail connector 8 and the threaded sleeve 15 are threadedly installed through a spiral rod 13. A rotating disk 14 is fixedly installed at one end of the spiral rod 13.

[0033] The sealing gasket 9 facilitates the sealing operation of the cover plate 2 during closure, thus better isolating it from the outside and preventing dust from entering. At the same time, the movable groove 10 can cooperate with the limit buckle 3 and the docking sleeve 5 during docking, making it more convenient to use. By rotating the rotating disk 14, the screw rod 13 can be rotated synchronously, causing the threaded sleeve 15 on the outside of the screw rod 13 to move along the thread direction of the screw rod 13, thereby driving the mounting plate 16 to move, so that the rack 17 can mesh with the gear 19.

[0034] Reference Figures 2-5 The rack 17 and the gear 19 mesh with each other. The external wiring 11 passes through the inside of the fixed frame 20 and is located inside the limit clamp 23. The extrusion wheel 25 is slidably installed with the fixed frame 20 through the slide groove 26. The movable plate 22 is movably connected to the inside of the fixed frame 20 through the spring 29.

[0035] The rack 17 can mesh with the gear 19, allowing the outer connector 18 to rotate inside the mounting bracket 12. This allows for better space avoidance during installation of the outer connector 18 and the pigtail connector 8, making the installation process more convenient and faster. It also pushes the movable plate 22 inward, causing the spring 29 to deform and the limiting clamps 23 to move closer together, thereby limiting the outer wire 11 inside the limiting clamps 23.

[0036] Reference Figure 1 and Figure 2 The outer side of the distribution box 1 is fixedly installed with a mating sleeve 5 corresponding to the limit buckle 3. The mating sleeve 5 and the mating hole 4 are fixed by a fixing knob 6. The limit buckle 3 is provided with a mating hole 4 corresponding to the fixing knob 6.

[0037] By connecting the limit buckle 3 and the docking sleeve 5, the junction box 1 and the cover plate 2 can be fitted together. The limit buckle 3 and the docking sleeve 5 can be limited by the fixing knob 6, so that the junction box 1 and the cover plate 2 can be fixed at the same time during use, making it more convenient and quick to operate.

[0038] In operation, this invention works as follows: the external wiring 11 is passed through the inner side of the limiting clamp 23. The telescopic rod 21 extends and retracts, lifting the base plate 27. During the movement of the base plate 27, the top rod 28 slides along the interior of the fixed frame 20, causing the fixed frame 20 to press against the extrusion wheel 25. The extrusion wheel 25 then slides along the interior of the slide groove 26, allowing it to slide along the inclined surface of the inclined plate 24. This pushes the movable plate 22 inward, causing the spring 29 to deform. This results in the limiting clamps 23 moving closer together, thus limiting the movement of the external wiring 11 inside the limiting clamps 23. The process of limiting the external wiring 11 is more convenient, preventing the optical cable from separating and falling off due to external pulling. By rotating the rotating disk 14, the spiral rod 13 can be rotated synchronously, and the threaded sleeve 15 on the outside of the spiral rod 13 can move along the thread direction of the spiral rod 13, thereby driving the mounting plate 16 to move, so that the rack 17 can mesh with the gear 19, and the external connector 18 can rotate inside the mounting frame 12. This allows for better space avoidance during the installation of the external connector 18 and the pigtail connector 8, making the installation process more convenient and faster.

[0039] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
