Description

Technical Field

[0001] This invention belongs to the field of optical communication technology, specifically a one-to-two fiber optic connection harness. Background Technology

[0002] One-to-two fiber optic connectors are key passive components in optical communication systems for splitting and interconnecting optical signals. They are integrated or field-assembled with a main cable, split nodes, and two branch cables to distribute or combine one optical signal into two, supporting signal transmission needs in scenarios such as FTTH, high-density cabling in data centers, and industrial control.

[0003] In existing technologies, the branching nodes of this type of cable harness are mostly packaged in one-piece injection molding or fixed-angle housings. The branching angles are usually fixed specifications such as 30°, 45°, and 60°, which can only adapt to the installation spacing of specific equipment. They are difficult to cope with complex working conditions where the location of equipment on site is varied and the cabling space is limited. For example, in a small weak current box or a dense cabinet environment in a computer room, fixed-angle branching can easily lead to excessive bending of the branch cable, exceeding the minimum bending radius requirement of optical fiber, causing problems such as increased additional loss and decreased signal stability. It also increases the difficulty of construction and the cost of cable management. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a one-to-two split-type optical fiber connection harness, which effectively solves the problem that it is currently difficult to adjust the branch angle according to the requirements.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a one-to-two split optical fiber connection bundle, including a main optical fiber cable, two branch optical fiber cables symmetrically arranged on the main optical fiber cable, an adjustment mechanism on the outside of the main optical fiber cable, and connection connectors at the ends of the main optical fiber cable and the two branch optical fiber cables.

[0006] The adjustment mechanism includes a mounting frame fixedly sleeved on the outside of the main optical fiber cable. Two U-shaped round rods are symmetrically fixedly connected to the outside of the mounting frame. Lifting blocks are movably sleeved on the outside of each of the two U-shaped round rods. Movable rods are rotatably connected to the sides of the two lifting blocks that are far apart from each other. Sleeve blocks are fixedly sleeved on the outside of each of the two branch optical fiber cables. The tops of the two movable rods are rotatably connected to the outside of the two sleeve blocks, respectively.

[0007] Preferably, the outer side of the mounting frame is provided with a U-shaped plate, which is fixed between two lifting blocks. The outer side of the U-shaped plate is provided with a movable plate, and two connecting columns are symmetrically fixedly connected to the side of the movable plate near the mounting frame. The ends of the two connecting columns away from the movable plate are fixedly connected with insert rods, and the two connecting columns pass through the U-shaped plate and are movably connected to the U-shaped plate.

[0008] Preferably, the outer side of the mounting frame is symmetrically fixedly connected to two side plates, and the two side plates are provided with multiple insertion holes at equal distances on the side away from the mounting frame, and the two insertion rods are respectively inserted into two corresponding insertion holes.

[0009] Preferably, a threaded rod is fixedly connected to the outer side of the U-shaped plate, and a threaded cylinder is threadedly sleeved on the outer side of the threaded rod. A handwheel is fixedly connected to the end of the threaded cylinder away from the U-shaped plate, and the movable plate is located outside the threaded cylinder.

[0010] Preferably, the outer side of the threaded cylinder is fixedly sleeved with an outer ring one and an outer ring two, the outer ring two being located between the outer ring one and the U-shaped plate, and the movable plate being located between the outer ring one and the outer ring two, with the movable plate abutting against the outer ring one.

[0011] Preferably, the dustproof mechanism includes a protective shell fixed to the outside of the connecting joint, an installation ring fixedly sleeved on the outside of the protective shell, a sealing ring fixedly connected to the outside of the installation ring, a protective cover on the outside of the connecting joint, and the end of the protective cover fitting against the sealing ring.

[0012] Preferably, two L-shaped round rods are symmetrically fixedly connected between the protective shell and the mounting ring. A sliding plate is movably sleeved between the two L-shaped round rods. A rotating shaft is rotatably connected to the outer side of the sliding plate. A side block is fixedly connected to the end of the rotating shaft away from the sliding plate. The side block is fixed to the outer side of the protective cover.

[0013] Preferably, a positioning rod is fixedly connected to the side of the side block near the mounting ring, and the mounting ring is provided with a positioning hole, through which the positioning rod passes.

[0014] Preferably, an L-shaped positioning cylinder is fixedly connected to the outer side of the protective shell, and the inner diameter of the L-shaped positioning cylinder is equal to the outer diameter of the positioning rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. In this invention, the movement of the U-shaped plate can drive the movement of two sleeve blocks, enabling the rotation of two branch optical fiber cables. By rotating the handwheel, the movement of the movable plate can be driven, allowing the two insertion rods to be inserted into two corresponding insertion holes respectively. This facilitates the fixing of the position of the U-shaped plate, and subsequently the fixing of the position of the two branch optical fiber cables, thereby facilitating the adjustment of the branch angle as needed.

[0017] 2. This invention allows the protective cover to be rotated and moved, facilitating the insertion of the positioning rod through the positioning hole. This enables the protective cover to move under the force of two springs until it fits against the sealing ring, thus facilitating the sealing and protection of the connection joint when not in use and preventing dust from adhering.

[0018] 3. This invention allows the protective cover to be rotated and moved, facilitating the insertion of the positioning rod into the L-shaped positioning cylinder. This enables the protective cover to move under the action of two springs until the side block abuts against the L-shaped positioning cylinder, thus achieving fixation of the protective cover after it is removed from the outside of the connecting joint, thereby facilitating the normal use of the connecting joint.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0028] Example 1, by Figures 1-5 The present invention relates to a one-to-two split optical fiber connection harness, comprising a main optical fiber cable 1, two branch optical fiber cables 4 symmetrically arranged on the main optical fiber cable 1, an adjustment mechanism 2 on the outer side of the main optical fiber cable 1, and a connection connector 5 at the end of the main optical fiber cable 1 and the two branch optical fiber cables 4. The splitting node of the entire connection harness has a built-in micro PLC splitter. The optical signal is input at the main end, and the splitter evenly splits it into two paths, which are output from the two branch ends, or they can be combined in reverse.

[0029] In Example 2, based on Example 1, the adjustment mechanism 2 includes a mounting frame 201 fixedly sleeved on the outside of the main optical fiber cable 1. Two U-shaped rods 202 are symmetrically fixedly connected to the outside of the mounting frame 201. Lifting blocks 203 are movably sleeved on the outside of each of the two U-shaped rods 202. Movable rods 205 are rotatably connected to the sides of the two lifting blocks 203 that are far apart from each other. Sleeve blocks 204 are fixedly sleeved on the outside of each of the two branch optical fiber cables 4. The top ends of the two movable rods 205 are rotatably connected to the outside of the two sleeve blocks 204, respectively. A U-shaped plate 206 is provided on the outside of the mounting frame 201, fixed between the two lifting blocks 203. A movable plate 2010 is provided on the outside of the U-shaped plate 206. Two connecting posts 209 are symmetrically fixedly connected to the side of the movable plate 2010 closest to the mounting frame 201.

Two side plates 208 are symmetrically fixedly connected to the outer side of the mounting frame 201. Multiple insertion holes 207 are equally spaced on the side of each side plate 208 away from the mounting frame 201. Two insertion rods 2015 are respectively inserted into two corresponding insertion holes 207. A threaded rod 2016 is fixedly connected to the outer side of the U-shaped plate 206. A threaded cylinder 2011 is threadedly sleeved on the outer side of the threaded rod 2016. A handwheel 2012 is fixedly connected to the end of the threaded cylinder 2011 away from the U-shaped plate 206. The movable plate 2010 is located on the outside of the threaded cylinder 2011. An outer ring 1 2013 and an outer ring 2 2014 are fixedly sleeved on the outside of the threaded cylinder 2011. The outer ring 2 2014 is located between the outer ring 1 2013 and the U-shaped plate 206. The movable plate 2010 is located between the outer ring 1 2013 and the outer ring 2 2014, and the movable plate 2010 abuts against the outer ring 1 2013.

[0030] First, rotate the handwheel 2012 counterclockwise to drive the threaded cylinder 2011 to rotate and move outside the threaded rod 2016. At the same time, the outer ring 2014 moves to push the movable plate 2010. The two connecting columns 209 drive the two insertion rods 2015 to move until the two insertion rods 2015 are removed from the two corresponding insertion holes 207. Then, the U-shaped plate 206 moves longitudinally, driving the two lifting blocks 203 to slide along the two U-shaped round rods 202. The two movable rods 205 drive the two sleeve blocks 204 to move, realizing the rotation of the two branch optical fiber cables 4. Then, rotate the handwheel 2012 clockwise to move the outer ring 2013 and push the movable plate 2010 until the two insertion rods 2015 are inserted into the two corresponding insertion holes 207. The position of the U-shaped plate 206 is fixed, and the position of the two branch optical fiber cables 4 is fixed. Finally, the branch angle is adjusted according to the requirements.

[0031] In Example 3, based on Example 1, the dustproof mechanism 3 includes a protective shell 301 fixed to the outside of the connecting joint 5. A mounting ring 309 is fixedly sleeved on the outside of the protective shell 301. A sealing ring 3010 is fixedly connected to the outside of the mounting ring 309. A protective cover 308 is provided on the outside of the connecting joint 5. The end of the protective cover 308 fits against the sealing ring 3010. Two L-shaped round rods 302 are symmetrically fixedly connected between the protective shell 301 and the mounting ring 309. A sliding plate 303 is movably sleeved between the two L-shaped round rods 302. A rotating shaft 305 is rotatably connected to the outside of the sliding plate 303. A side block 307 is fixedly connected to the end of the rotating shaft 305 away from the sliding plate 303. The side block 307 is fixed to the outside of the protective cover 308. A positioning rod 306 is fixedly connected to the side of the side block 307 near the mounting ring 309. A positioning hole 3012 is provided on the mounting ring 309. The positioning rod 306 passes through the positioning hole 3012.

[0032] First, pull and rotate the protective cover 308. The side block 307 and the rotating shaft 305 drive the slide plate 303 to slide along the two L-shaped round rods 302 and approach the mounting ring 309. At this time, both springs 3011 are compressed. Then, push the protective cover 308 so that the positioning rod 306 passes through the positioning hole 3012. Then release the protective cover 308. At this time, the protective cover 308 moves under the elastic force of the two springs 3011 until it fits against the sealing ring 3010, thus sealing the connecting joint 5. Finally, protect the connecting joint 5 when it is not in use to prevent dust from adhering.

[0033] In Example 4, based on Example 1, an L-shaped positioning cylinder 304 is fixedly connected to the outer side of the protective shell 301, and the inner diameter of the L-shaped positioning cylinder 304 is equal to the outer diameter of the positioning rod 306.

[0034] First, pull and rotate the protective cover 308. The side block 307 and the rotating shaft 305 drive the slide plate 303 to slide along the two L-shaped round rods 302 and approach the mounting ring 309. At this time, both springs 3011 are compressed. Then push the protective cover 308 so that the positioning rod 306 is inserted into the L-shaped positioning cylinder 304. Then release the protective cover 308. At this time, the protective cover 308 moves under the elastic force of the two springs 3011 until the side block 307 abuts against the L-shaped positioning cylinder 304, thereby fixing the protective cover 308 after it is removed from the outside of the connecting joint 5, so that the connecting joint 5 can be used normally.
