Description

Technical Field

[0001] The present invention relates to the technical field of optical fiber arrangement, and in particular to a multi-core optical fiber precision arrangement device. Background Art

[0002] With the rapid development of information technology, multi-core optical fiber has been widely used in communication networks. Especially in scenarios that require high-bandwidth and low-loss transmission, multi-core optical fiber has become an indispensable infrastructure due to its 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, and the color of the optical fibers becomes an important basis for positioning and installation. Different colored optical fibers represent different transmission channels or functions. Therefore, during the installation process, it is necessary to ensure that each optical fiber can be accurately connected to the designated position.

[0004] However, the existing installation method lacks an effective pre-positioning arrangement device, and cannot pre-arrange according to the color of the optical fiber. As a result, during the installation process, operators need to spend a lot of time and energy to identify and distinguish optical fibers of different colors. The slightest carelessness may lead to optical fiber docking errors, which in turn affects 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 and knotting during the installation process, further increasing the difficulty and risk of installation.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] A multi-core optical fiber precision arrangement device, see Figure 1-Figure 6 , which comprises: a frame plate 1, two groups of support blocks, and a plurality of driving and positioning mechanisms;

[0032] The frame plate 1 is a long strip structure; each support block group is provided with a plurality of support blocks 2;

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

[0034] A group of support blocks are respectively arranged on both sides of the frame plate 1 along the length direction, each group of support blocks includes a number of support blocks 2 arranged at equal intervals, and 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 plate mechanisms are in an open state for placing corresponding optical fibers, and in the second state, a pair of clamping plate mechanisms are in a closed state, and the positioning cavity 34 formed therein is used to clamp optical fibers of corresponding diameters.

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

[0036] In order to facilitate the precise positioning of each optical fiber, it is convenient to position and install the 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, a first clamping plate 32 and a first clamping plate 33 pivotally connected to the support rod 31, and a positioning cavity 34 is formed between the first clamping plate 32 and the second clamping plate 33, and the positioning cavity 34 is used to clamp and position the optical fiber. Through the setting of the positioning structure 3, the optical fiber can be accurately positioned and arranged, avoiding docking errors and entanglement during the installation process. The device of the present invention can be customized and adjusted according to actual needs to adapt to multi-core optical fibers of different specifications and quantities. When in use, each optical fiber is installed in the positioning cavity 34 between the first clamping plate 32 and the second clamping plate 33 corresponding to its position. Through the setting of the positioning structure 3, it is convenient to pre-position each optical fiber according to the installation requirements to avoid the phenomenon of optical fiber entanglement during the installation process.

[0037] Furthermore, in order to facilitate fine-tuning of the opening size of the movable ends of the first clamping plate 32 and the second clamping plate 33: a rotating rod 311 is fixedly inserted on the support rod 31, and the first clamping plate 32 and the second clamping plate 33 are rotatably mounted on the rotating rod 311. It is convenient for the optical fiber to be inserted into the positioning cavity 34 through the first clamping plate 32 and the second clamping plate 33. The rotation design of the rotating rod 311 and the clamping plate makes the insertion and positioning of the optical fiber more convenient and quick. 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 adapt to optical fibers of different diameters or shapes. The versatility and flexibility of the device are enhanced.

[0038] Further, in order to facilitate the movement of the movable ends of the first clamping plate 32 and the second clamping plate 33 to open or merge: the positioning structure 3 is provided with a driving member 4 for driving the movable ends of the first clamping plate 32 and the second clamping plate 33 to open or close, and the driving member 4 includes a bracket 41 mounted on the support rod 31 and fixedly connected to the support block 2, a lifting seat 42 mounted on the bracket 41 and in contact with the outer periphery of the first clamping plate 32 and the second clamping plate 33, and a traction spring 44. Two groups of traction springs 44 are respectively connected to one end of the lifting seat 42 and the corresponding outer periphery of the first clamping plate 32 and the second clamping plate 33. The design of the driving member 4 allows the movable ends of the first clamping plate 32 and the second clamping plate 33 to be conveniently opened or closed, thereby facilitating the insertion and positioning of the optical fiber. By adjusting the rotation angle of the first clamping plate 32 and the second clamping plate 33 relative to the rotating rod 311, and using the elastic force of the traction spring 44, the opening size of the positioning cavity 34 can be fine-tuned to adapt to optical fibers of different diameters or shapes. The versatility and flexibility of the device are enhanced. When it is necessary to insert the optical fiber, the lifting plate 43 is moved downward to drive the lifting seat 42 to move downward. 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, so that the first clamping plate 32 and the second clamping plate 33 rotate around the rotating rod 311, and then the movable ends of the first clamping plate 32 and the second clamping plate 33 are opened to form a larger opening, which is convenient for placing the optical fiber in the positioning cavity 34. When 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 and resets, and at the same time drives the movable ends of the first clamping plate 32 and the second clamping plate 33 to move closer and merge, so that the optical fiber is tightly positioned in the positioning cavity 34.

[0039] Furthermore, in order to facilitate the lifting seat 42 to drive the first clamping plate 32 and the second clamping plate 33 to move closer, the front and rear end vertical plates of the lifting seat 42 are provided with arc grooves 421. The design of the arc grooves 421 makes the movement of the lifting seat 42 more stable and accurate, and ensures the reliable placement and positioning of the optical fiber.

[0040] Furthermore, the driving member 4 also includes a support spring 45 sleeved on the support rod 31 and corresponding to the lifting plate 43 and the support block 2. When the lifting seat 42 moves downward, the lifting seat 42 drives the lifting plate 43 to squeeze the support spring 45 to make it contract and accumulate force. When the force on the lifting seat 42 is released, the lifting seat 42 is lifted under the action of the support spring 45, and the lifting seat 42 squeezes the first clamping plate 32 and the second clamping plate 33, so that the movable ends of the first clamping plate 32 and the second clamping plate 33 move closer, and then fix the optical fiber in the positioning cavity 34 to prevent the optical fiber from moving out of the positioning cavity 34. The design of the support spring 45 enables the lifting seat 42 to automatically reset after the driving force is released, thereby realizing the automatic squeezing 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, when the lifting plate 43 moves downward, it drives the lifting seat 42 to move downward together, and squeezes the support spring 45 to make it contract and accumulate force. At the same time, the lifting seat 42 moves downward and pulls the movable ends of the first clamping plate 32 and the second clamping plate 33 through the traction spring 44, so that the first clamping plate 32 and the second clamping plate 33 rotate around the rotating rod 311, and then the movable ends of the first clamping plate 32 and the second clamping plate 33 are opened to form a larger opening, which is convenient for placing the optical fiber in 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, so that the movable ends move close to each other and merge, and the optical fiber is tightly positioned in the positioning cavity 34. Due to the energy storage and release of the support spring 45, the rising and resetting process of the lifting seat 42 is smoother and faster, thereby improving the positioning efficiency and accuracy of the optical fiber.

[0041] Furthermore, in order to facilitate the adjustment of the distance between two adjacent groups of support blocks: the upper surface of the frame plate 1 is concave to form a mounting groove, the lower end of each support block 2 is embedded in the mounting groove, and the lower part of each support block 2 is provided with a through threaded hole, and the frame plate 1 is also integrated with an adjustment member 5, and the adjustment member 5 is used to adjust the distance between the remaining adjacent support blocks 2 in the middle of the two groups of support blocks, so that the two groups of multi-core optical fibers can be reliably distinguished; when one group of multi-core optical fibers is connected, the other group of multi-core optical fibers is the next backup group, which can ensure continuous optical fiber connection operations, and then while the backup group is performing optical fiber connection operations, the positioning mechanism on the first group of support blocks synchronously completes the precise arrangement of the multi-core optical fibers.

[0042] Furthermore, the adjusting member 5 includes an adjusting rod 51, and symmetrical and opposite threads 52 are respectively provided at the two end areas in the length direction of the adjusting rod 51. The adjusting rod 51 is respectively threadedly connected to the threaded hole of each support block 2 in the installation groove, and a plum blossom plate 53 is fixedly connected to one end of the adjusting rod 51 exposed to the frame plate; the addition of the plum blossom plate 53 makes it easier and more labor-saving to rotate the adjusting rod 51, and the user can complete the adjustment operation without using additional tools. When it is necessary to adjust the distance between the two adjacent groups of support blocks 2, the user first holds the plum blossom plate 53 and rotates it forcefully. Since the symmetrical and opposite threads 52 on the adjusting rod 51 match the threaded holes inside the support block 2, rotating the adjusting rod 51 will cause the support block groups located on both sides of its length direction to move in opposite directions. By controlling the direction and force of rotation, the user can accurately adjust the distance between the two groups of support blocks to meet the spacing requirements between the assembled optical cables.

[0043] Furthermore, in order to facilitate observation of the distance between the two groups of support blocks, a spacing display mechanism 6 is provided on the center area of ​​the length direction of the upper surface of one of the vertical plates of the frame plate 1, and the spacing display mechanism 6 is used to display the distance between the two adjacent groups of support blocks; the distance display structure 6 includes a scale plate 61 and a card plate 62, and the card plate 62 is slidably connected along the scale plate 61. Through the coordinated use of the scale plate 61 and the card plate 62, the user can intuitively see the distance between the adjacent support blocks 2 without the need for additional measurement or calculation. The fine scale lines on the scale plate 61 make the adjustment and reading of the spacing more precise and reduce errors. The design of the spacing display structure 6 allows the user to immediately observe the change in the spacing while adjusting the spacing between the two groups of support blocks, thereby improving the convenience and efficiency of operation.

[0044] When the adjustment rod 51 is rotated, the support blocks located on both sides of the center position are specifically the left support block 21 and the right support block 22. The left support block 21 and the right support block 22 will move in opposite directions. Since the scale plate 61 is fixedly connected to the left support block 2, and the card plate 62 is fixedly connected to the right support block 2, as the right support block 2 moves, the card plate 62 will also slide on the scale plate 61. The indicator arrow or pointer on the card plate 62 will then point to a certain scale line on the scale plate 61, and the value corresponding to the scale line is the distance between the two groups of support blocks. The user can quickly and accurately obtain the spacing information by observing the relative position of the indicator arrow or pointer on the card plate 62 and the scale plate 61.

[0045] Furthermore, in order to facilitate the positioning, installation and guided movement of the scale plate 61: a groove 11 is provided on the vertical plate of the frame plate 1, and the scale plate 61 is embedded in the groove 11. By providing the groove 11 and embedding the scale plate 61, the scale plate 61 is accurately positioned and installed, and the side wall of the groove 11 provides a stable guide for the scale plate 61, so that the scale plate 61 can maintain a straight line motion during the movement process, avoiding errors caused by offset.

[0046] The above are only preferred specific implementation methods of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes based on the technical solution and concept of the present application within the technical scope disclosed in the present application, which should be covered by the protection scope of the present application.
