Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of optical fiber arrangement, in particular to a multi-core optical fiber precise arrangement device. BACKGROUND

[0002] With the rapid development of information technology, multi-core optical fibers have been widely used in communication networks. Especially in scenarios requiring high bandwidth and low loss transmission, multi-core optical fibers have become indispensable infrastructure due to their superior performance.

[0003] When installing multi-core optical fibers (especially multi-color optical fibers such as 12-color optical fibers), the installation process of multi-core optical fibers mainly relies on manual operation, in which the color of the optical fiber becomes an important basis for positioning installation. Different colors of optical fibers represent different transmission channels or functions, so it is necessary to ensure that each optical fiber can be accurately and correctly connected to the designated position during installation.

[0004] However, the existing installation method lacks an effective pre-positioning arrangement device, which cannot pre-arrange according to the color of the optical fiber. This results in the need for operators to spend a lot of time and effort to identify and distinguish different colors of optical fibers during installation, and any mistake can lead to incorrect optical fiber connection, thereby affecting the performance and stability of the entire communication system. In addition, due to the lack of an effective arrangement device, the optical fiber is prone to entanglement, knotting and other problems during installation, further increasing the difficulty and risk of installation. SUMMARY

[0005] To solve the above problems, the present application provides a multi-core optical fiber precise arrangement device, which allows multi-core optical fibers to be pre-positioned according to color, ensuring easy and reliable optical fiber connection during installation.

[0006] A multi-core optical fiber precise arrangement device, characterized in that it comprises:

[0007] a frame plate, which is a long strip structure;

[0008] two groups of support block groups, each group of support block groups being provided with a plurality of support blocks;

[0009] and a plurality of drive positioning mechanisms, each drive positioning mechanism comprising a positioning structure and a drive member driving the positioning structure to act, the positioning structure comprising a pair of clamping plate mechanisms, and the drive member driving the pair of clamping plate mechanisms to open or close;

[0010] The frame plate has a set of support blocks on both sides along its length. Each set of support blocks includes several support blocks arranged at equal intervals. A positioning structure is fixed on the upper surface of each support block. The positioning structure has two states. In the first state, a pair of clamping mechanisms are in the open state and are used to insert the corresponding optical fiber. In the second state, a pair of clamping mechanisms are in the closed state and the positioning cavity formed therein is used to hold the optical fiber of the corresponding diameter.

[0011] The number of support blocks is the same as the number of positioning structures.

[0012] Its further features are:

[0013] A pair of clamping mechanisms includes a support rod, a first clamping plate, and a second clamping plate. A rotating rod is fixedly inserted into the top of the support rod. The first clamping plate and the second clamping plate are rotatably mounted on the rotating rod. The first clamping plate and the second clamping plate form a positioning cavity when closed.

[0014] The drive component bracket, lifting seat, lifting plate, and traction spring are described. The bracket includes a base plate and a column mechanism. The column mechanism of the bracket is fixedly connected to the support block. The inner cavity of the lifting seat is fixedly connected to the lifting plate to form an integrated lifting frame. The lifting plate is located below the base plate. The lifting frame moves up and down along the column mechanism. The support rod passes through the lifting plate and the base plate, protrudes upward, and is connected to the first clamping plate and the second clamping plate through a rotating rod. The outer sides of the first clamping plate and the second clamping plate are respectively fixedly connected to one end of the corresponding side traction spring. The other end of the traction spring is fixedly installed on the inner wall of the corresponding side plate of the lifting seat at the corresponding position.

[0015] The driving component also includes a support spring sleeved on the outer periphery of the support rod, and the support spring is arranged between the lifting plate and the support block;

[0016] The front and rear end plates of the lifting platform are provided with arc-shaped grooves, and the design of the arc-shaped grooves makes the optical fiber reliably positioned.

[0017] The upper surface of the frame plate is recessed to form a mounting groove. The lower end of each support block is embedded in the mounting groove. Each support block has a through threaded hole at its lower part. The frame plate also integrates an adjustment component, which is used to adjust the spacing between the remaining adjacent support blocks in the middle of the two sets of support blocks, so that the two sets of multi-core optical fibers can be reliably distinguished. After one set of multi-core optical fibers is connected, the other set of multi-core optical fibers becomes the backup set, which can ensure continuous optical fiber connection operation. Then, while the backup set is connected, the positioning mechanism on the support block set of the first set simultaneously completes the precise arrangement of the multi-core optical fibers.

[0018] The adjusting component includes an adjusting rod, with symmetrical and opposite threads at both ends along the length of the adjusting rod. The adjusting rod is threaded to the threaded holes of each support block in the mounting groove, and a perforated plate is fixed to one end of the adjusting rod exposed on the frame plate.

[0019] A spacing display mechanism is provided on the center region of the upper surface of one of the vertical plates of the frame plate along the length direction. The spacing display mechanism is used to display the distance between two adjacent sets of support blocks.

[0020] The distance display structure includes a scale plate and a locking plate, which are located in the center of two adjacent support blocks corresponding to two sets of support blocks respectively. One support block is fixed to the scale plate and is set to its 0 scale, while the other support block is fixed to the locking plate. The locking plate is slidably connected along the scale plate.

[0021] Compared with existing technologies, this invention provides a multi-core optical fiber precision alignment device. Through the design of the positioning structure, precise positioning and alignment of the optical fibers can be achieved, avoiding splicing errors and tangling during installation. Using this invention for optical fiber installation can significantly improve installation efficiency and reduce installation time and costs. The device of this invention can be customized and adjusted according to actual needs to accommodate multi-core optical fibers of different specifications and quantities. Attached Figure Description

[0030] 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, and 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.

[0031] A multi-core optical fiber precision alignment device, see Figures 1-6 It includes: frame plate 1, two sets of support block groups, and several drive and positioning mechanisms;

[0032] Frame 1 is a long strip structure; each group of support blocks is provided with several support blocks 2;

[0033] Each drive positioning mechanism includes a positioning structure 3 and a drive member 4 that drives the positioning structure 3 to move. The positioning structure 3 includes a pair of clamping mechanisms, and the drive member 4 drives the pair of clamping mechanisms to open or close.

[0034] A set of support blocks is provided on both sides of the frame plate 1 along the length direction. Each set of support blocks includes several support blocks 2 arranged at equal intervals. A positioning structure 3 is fixed on the upper surface of each support block 2. The positioning structure 3 has two states. In the first state, a pair of clamping mechanisms are in the open state and are used to insert the corresponding optical fiber. In the second state, a pair of clamping mechanisms are in the closed state and the positioning cavity 34 formed therein is used to hold the optical fiber of the corresponding diameter.

[0035] The number of support blocks 2 is the same as the number of positioning structures 3.

[0036] To facilitate precise positioning and installation of each optical fiber, the positioning structure 3 includes a support rod 31 fixedly connected to the support block 2 and protruding from the frame plate 1, and two first clamping plates 32 and 33 pivotally connected to the support rod 31. A positioning cavity 34 is formed between the first clamping plate 32 and the second clamping plate 33, which is used to hold and position the optical fiber. The positioning structure 3 enables precise positioning and arrangement of the optical fibers, avoiding misalignment and tangling during installation. The device of this invention can be customized and adjusted according to actual needs to accommodate multi-core optical fibers of different specifications and quantities. In use, each optical fiber is installed in the positioning cavity 34 between the first clamping plate 32 and the second clamping plate 33 according to its corresponding position. The positioning structure 3 facilitates pre-positioning of each optical fiber according to installation requirements, preventing tangling during installation.

[0037] Furthermore, to facilitate fine-tuning of the opening size at the movable ends of the first clamping plate 32 and the second clamping plate 33, a rotating rod 311 is fixedly inserted into the support rod 31, and the first clamping plate 32 and the second clamping plate 33 are rotatably fitted onto the rotating rod 311. This facilitates the insertion of the optical fiber into the positioning cavity 34 through the first clamping plate 32 and the second clamping plate 33. The rotating design of the rotating rod 311 and the clamping plates makes the insertion and positioning of the optical fiber more convenient and faster. By adjusting the rotation angle of the second clamping plate 33 relative to the first clamping plate 32, the opening size of the positioning cavity 34 can be fine-tuned to accommodate optical fibers of different diameters or shapes, enhancing the versatility and flexibility of the device.

[0038] Furthermore, to facilitate the opening or closing of the movable ends of the first clamping plate 32 and the second clamping plate 33, the positioning structure 3 is equipped with a driving component 4 for opening or closing the movable ends of the first clamping plate 32 and the second clamping plate 33. The driving component 4 includes a bracket 41 fitted on the support rod 31 and fixedly connected to the support block 2, a lifting seat 42 fitted on the bracket 41 and abutting against the outer periphery of the first clamping plate 32 and the second clamping plate 33, and traction springs 44. Two sets of traction springs 44 are respectively connected to one end of the lifting seat 42 and the corresponding outer periphery positions of the first clamping plate 32 and the second clamping plate 33. The design of the driving component 4 allows the movable ends of the first clamping plate 32 and the second clamping plate 33 to be easily opened or closed, thereby facilitating the insertion and positioning of optical fibers. By adjusting the rotation angle of the first clamping plate 32 and the second clamping plate 33 relative to the rotating rod 311, and by utilizing the elastic force of the traction springs 44, the opening size of the positioning cavity 34 can be finely adjusted to accommodate optical fibers of different diameters or shapes. This enhances the versatility and flexibility of the device. When an optical fiber needs to be inserted, the lifting plate 43 is moved downwards, causing the lifting seat 42 to move downwards as well. The lifting seat 42 pulls the movable ends of the first clamping plate 32 and the second clamping plate 33 through the traction spring 44, causing the first clamping plate 32 and the second clamping plate 33 to rotate around the rotating rod 311. This opens the movable ends of the first clamping plate 32 and the second clamping plate 33, forming a larger opening to facilitate the placement of the optical fiber into the positioning cavity 34. After the optical fiber is placed, the lifting plate 43 is released. At this time, under the elastic force of the traction spring 44, the lifting seat 42 rises back to its original position, simultaneously causing the movable ends of the first clamping plate 32 and the second clamping plate 33 to move closer together and merge, firmly positioning the optical fiber in the positioning cavity 34.

[0039] Furthermore, to facilitate the movement of the movable ends of the first clamping plate 32 and the second clamping plate 33 via the lifting seat 42, arc-shaped grooves 421 are provided on the front and rear end upright plates of the lifting seat 42. The design of the arc-shaped grooves 421 makes the movement of the lifting seat 42 more stable and precise, and ensures the reliable placement and positioning of the optical fiber.

[0040] Furthermore, the driving component 4 also includes a support spring 45 mounted on the support rod 31, corresponding to the space between the lifting plate 43 and the support block 2. When the lifting seat 42 moves downward, it drives the lifting plate 43 to compress the support spring 45, causing it to contract and store force. When the force on the lifting seat 42 is released, the lifting seat 42 rises under the action of the support spring 45, and the lifting seat 42 compresses the first clamping plate 32 and the second clamping plate 33, causing the movable ends of the first clamping plate 32 and the second clamping plate 33 to move closer together, thereby fixing the optical fiber in the positioning cavity 34 and preventing the optical fiber from moving out of the positioning cavity 34. The design of the support spring 45 allows the lifting seat 42 to automatically reset after the driving force is released, thereby realizing automatic compression of the first clamping plate 32 and the second clamping plate 33, ensuring that the optical fiber is firmly fixed in the positioning cavity 34 and preventing the optical fiber from moving out of the positioning cavity 34. When it is necessary to insert the optical fiber, the lifting plate 43 moves downward, driving the lifting seat 42 to move downward together, and compressing the support spring 45 to contract and store force. Simultaneously, the downward movement of the lifting seat 42 also pulls the movable ends of the first clamping plate 32 and the second clamping plate 33 through the traction spring 44, causing the first clamping plate 32 and the second clamping plate 33 to rotate around the rotating rod 311. This opens the movable ends of the first clamping plate 32 and the second clamping plate 33, forming a larger opening to facilitate the placement of the optical fiber into the positioning cavity 34. After the optical fiber is placed, the driving force on the lifting plate 43 is released. At this time, under the elastic force of the support spring 45, the lifting plate 43 and the lifting seat 42 rise and reset together. When the lifting seat 42 rises, the traction spring 44 applies pressure to the movable ends of the first clamping plate 32 and the second clamping plate 33, causing their movable ends to move closer and merge, firmly positioning the optical fiber in the positioning cavity 34. Due to the energy storage and release function of the support spring 45, the rising and resetting process of the lifting seat 42 is more stable and faster, thereby improving the positioning efficiency and accuracy of the optical fiber.

[0041] Furthermore, to facilitate the adjustment of the distance between two adjacent sets of support blocks: the upper surface of the frame plate 1 is recessed to form an installation groove, and the lower end of each support block 2 is embedded in the installation groove. Each support block 2 has a through threaded hole at its lower part. The frame plate 1 also integrates an adjustment component 5, which is used to adjust the spacing between the remaining adjacent support blocks 2 in the middle of the two sets of support blocks, so that the two sets of multi-core optical fibers can be reliably distinguished. After one set of multi-core optical fibers is connected, the other set of multi-core optical fibers becomes the backup set, which can ensure continuous optical fiber connection operation. Then, while the backup set is performing optical fiber connection operation, the positioning mechanism on the support block set of the first set simultaneously completes the precise arrangement of the multi-core optical fibers.

[0042] Furthermore, the adjusting component 5 includes an adjusting rod 51. Symmetrical, opposing threads 52 are formed at both ends of the adjusting rod 51 along its length. The adjusting rod 51 is threaded into the threaded holes of each support block 2 within the mounting groove. A perforated plate 53 is fixed to the end of the adjusting rod 51 exposed on the frame plate. The addition of the perforated plate 53 makes rotating the adjusting rod 51 easier and less strenuous, allowing the user to complete the adjustment operation without additional tools. When adjusting the distance between two adjacent support block groups 2, the user first grasps the perforated plate 53 and rotates it forcefully. Because the symmetrical, opposing threads 52 on the adjusting rod 51 match the threaded holes inside the support block 2, rotating the adjusting rod 51 causes the support block groups located on both sides of its length to move in opposite directions. By controlling the direction and force of rotation, the user can precisely adjust the distance between the two support block groups to meet the spacing requirements of the assembled optical cables.

[0043] Furthermore, to facilitate observation of the distance between the two sets of support blocks, a spacing display mechanism 6 is installed on the center area of ​​the upper surface of one of the vertical plates of the frame plate 1 along its length. The spacing display mechanism 6 is used to indicate the distance between adjacent sets of support blocks. The spacing display structure 6 includes a scale plate 61 and a locking plate 62. The locking plate 62 is slidably connected to the scale plate 61. Through the cooperation of the scale plate 61 and the locking plate 62, the user can intuitively see the distance between adjacent support blocks 2 without additional measurement or calculation. The fine scale lines on the scale plate 61 make the adjustment and reading of the spacing more accurate, reducing errors. The design of the spacing display structure 6 allows the user to immediately observe the change in spacing while adjusting the spacing between the two sets of support blocks, improving the convenience and efficiency of operation.

[0044] When the adjusting rod 51 is rotated, the support blocks located on either side of the center position—specifically, the left support block 21 and the right support block 22—move in opposite directions. Since the scale plate 61 is fixedly connected to the left support block 2, and the locking plate 62 is fixedly connected to the right support block 2, the locking plate 62 slides on the scale plate 61 as the right support block 2 moves. The indicator arrow or pointer on the locking plate 62 will then point to a specific graduation line on the scale plate 61. The value corresponding to this graduation line represents the distance between the two sets of support blocks. Users can quickly and accurately obtain the spacing information by observing the relative position of the indicator arrow or pointer on the locking plate 62 and the scale plate 61.

[0045] Furthermore, to facilitate the positioning, installation, and guiding movement of the scale plate 61, a groove 11 is provided on the upright plate of the frame plate 1, and the scale plate 61 is embedded in the groove 11. By creating the groove 11 and embedding the scale plate 61, precise positioning and installation of the scale plate 61 are achieved. The side wall of the groove 11 provides a stable guiding effect for the scale plate 61, enabling it to maintain linear movement during movement and avoiding errors caused by offset.
