Description

Technical Field

[0001] This utility model belongs to the field of optical fiber combiner technology, and more specifically, relates to an optical fiber combiner. Background Technology

[0002] An optical fiber combiner is an optical fiber device fabricated based on fused tapered fiber bundles. It is made by stripping the coating layer from a bundle of optical fibers, arranging them together in a certain way, heating them at high temperature to melt them, and simultaneously stretching the fiber bundle in opposite directions. The heated areas of the optical fibers melt to form a fused tapered fiber bundle.

[0003] A search revealed that a utility model patent for an optical fiber combiner, with Chinese patent announcement number (CN218767461 U), still has the following problem: after the optical fiber combiner is fixedly installed, if the user accidentally pulls on the optical fiber bundle, it can easily cause the optical fiber bundle to break, affecting the normal transmission of optical signals, which leads to a poor network experience for the user.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an optical fiber combiner in order to achieve a more practical purpose. Utility Model Content

[0005] To address the aforementioned technical problems, this invention provides an optical fiber bundle combiner to solve the current issue of users unintentionally pulling and breaking the optical fiber bundle.

[0006] The purpose and effect of this fiber optic combiner are achieved by the following specific technical means:

[0007] An optical fiber combiner includes a cover plate fixedly installed on the top of the optical fiber combiner body. Wiring ports are installed at both the left and right ends of the optical fiber combiner body. Two support rods are fixedly installed at both the left and right ends of the optical fiber combiner body. A cylinder is fixedly installed on the top of each support rod. A fixing frame is fixedly sleeved on the outer side of the top of the cylinder. A movable block is movably sleeved on the inner side of the bottom of the fixing frame. A rotating wheel is rotatably installed between the two movable blocks. A return spring is sleeved on the outer side of the cylinder. An mounting plate is fixedly installed on the bottom of the optical fiber combiner body.

[0008] Furthermore, the top end of the return spring is fixedly connected to the bottom of the movable block, the bottom end of the return spring is fixedly connected to the top of the support rod, and the rotating wheel is slidably installed with the cylinder through the movable block.

[0009] Furthermore, the fixed frame has an inverted U-shaped structure, and the movable block is positioned and connected to the fixed frame.

[0010] Furthermore, support columns are fixedly installed on both the left and right sides of the fixed frame, and an arc-shaped rod is fixedly installed at one end of each support column.

[0011] Furthermore, two fixing posts are fixedly installed on one side of the mounting plate, and a clamping plate is movably installed on one side of the mounting plate, with the mounting plate and the clamping plate slidably sleeved together.

[0012] Furthermore, a first slot is provided on one side of the mounting plate, and a second slot is provided on one side of the clamping plate, with the first slot and the second slot being positioned correspondingly.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, by rotating the wheel and the movable block, when the optical fiber is pulled and pressure is applied to the wheel, the movable block can squeeze the reset spring. Under the elastic action of the reset spring, the wheel can be elastically supported, reducing the pulling force on the optical fiber, reducing the probability of the optical fiber being pulled and broken, ensuring the normal transmission of optical signals, and enhancing the user's network experience.

[0015] In this utility model, the first slot of the mounting plate allows screws to pass through the first slot to fix the mounting plate in a flat mounting position. The bolts pass through the first and second slots and are connected to the nuts for installation, which allows the clamping plate and the mounting plate to clamp and fix the plate. The fiber optic combiner body is installed and fixed in two ways, which facilitates the fixed installation of the fiber optic combiner body. Attached Figure Description

[0025] Example:

[0026] As attached Figure 1 To be continued Figure 4 As shown:

[0027] This utility model provides an optical fiber combiner, including a cover plate 2 fixedly installed on the top of the optical fiber combiner body 1, wiring ports 3 installed on both the left and right ends of the optical fiber combiner body 1, two support rods 4 fixedly installed on both the left and right ends of the optical fiber combiner body 1, a cylinder 6 fixedly installed on the top of the support rod 4, a fixing frame 7 fixedly sleeved on the outer side of the top of the cylinder 6, a movable block 16 movably sleeved on the inner side of the bottom of the fixing frame 7, a rotating wheel 5 rotatably installed between the two movable blocks 16, a return spring 8 sleeved on the outer side of the cylinder 6, and an installation plate 11 fixedly installed on the bottom of the optical fiber combiner body 1.

[0028] By setting up a rotating wheel 5, a cylinder 6, a reset spring 8, and a movable block 16, when the user unintentionally pulls or pulls the optical fiber cable and applies pressure to the rotating wheel 5, the rotating wheel 5 and the movable block 16 can rotate and install, so that the movable block 16 can squeeze the reset spring 8. Under the elastic action of the reset spring 8, the rotating wheel 5 can be elastically supported, reducing the pulling force of the optical fiber cable and ensuring the normal transmission of optical signals.

[0029] The top end of the return spring 8 is fixedly connected to the bottom end of the movable block 16, the bottom end of the return spring 8 is fixedly connected to the top end of the support rod 4, and the rotating wheel 5 is slidably installed on the cylinder 6 through the movable block 16.

[0030] By setting the movable block 16, the rotation of the rotating wheel 5 and the movable block 16 are facilitated, and the movable block 16 and the cylinder 6 are slidably installed. When the rotating wheel 5 is subjected to the pulling force of the optical fiber, the elastic action of the return spring 8 can reduce the probability of the optical fiber being broken, thus ensuring the transmission of optical signals.

[0031] The fixed frame 7 has an inverted U-shaped structure, and the movable block 16 is matched and docked with the fixed frame 7.

[0032] The U-shaped structure of the fixed frame 7 facilitates the movable block 16 to dock with the fixed frame 7. The fixed installation of the fixed frame 7 and the cylinder 6 facilitates the sliding movement of the movable block 16 along the cylinder 6, and can limit the height movement of the movable block 16.

[0033] Among them, support columns 9 are fixedly installed on both the left and right sides of the fixed frame 7, and an arc-shaped rod 10 is fixedly installed on one end of the support column 9.

[0034] By setting up the support column 9, the arc-shaped rod 10 can be fixed and supported, allowing the arc-shaped rod 10 to restrict the optical fiber, better protect the optical fiber, and reduce the pulling force.

[0035] Two fixing posts 15 are fixedly installed on one side of the mounting plate 11, and a clamping plate 13 is movably installed on one side of the mounting plate 11. The mounting plate 11 and the clamping plate 13 are slidably sleeved together. A first slot 12 is opened on one side of the mounting plate 11, and a second slot 14 is opened on one side of the clamping plate 13. The positions of the first slot 12 and the second slot 14 are correspondingly set.

[0036] By setting up the mounting plate 11 and the clamping plate 13, it is convenient to use the first slot 12 set in the mounting plate 11 to pass through the first slot 12 to fix the mounting plate 11 in the plane mounting position, and also to use the external bolts to pass through the first slot 12 and the second slot 14 to connect with the external nut for installation. This allows the clamping plate 13 and the mounting plate 11 to clamp and fix the bracket. By using two installation methods to install and fix the fiber optic combiner body 1, it is convenient to fix and install the fiber optic combiner body 1.

[0037] The specific usage and function of this embodiment are as follows:

[0038] In this invention, the optical fiber is first arranged as follows: Figure 1As shown in the diagram, when a user accidentally pulls on the fiber optic cable while walking, the pulling force of the fiber optic cable applies pressure to the rotating wheel 5. The rotating wheel 5 drives the movable block 16 to slide along the cylinder 6, applying elastic pressure to the reset spring 8, reducing the pulling force on the fiber optic cable. The arc-shaped rod 10 further restricts the fiber optic cable, better cooperating with the rotating wheel 5 to protect the fiber optic cable, reducing the pulling force, and ensuring the transmission of optical signals. Then, the external screw passes through the first slot 12 to fix the mounting plate 11 in the flat mounting position, or the external bolt passes through the first slot 12 and the second slot 14 to be threadedly connected to the external nut, so that the clamping plate 13 and the mounting plate 11 clamp and fix the bracket, thereby facilitating the fixed installation of the fiber optic combiner body 1.

[0039] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
