Description

Technical Field

[0001] The invention relates to the field of optical fiber communication equipment, and in particular to an optical fiber aligner with a guiding structure. Background Art

[0002] A fiber aligner is a device used in fiber optic communication systems. Its main function is to convert the transmission light in the optical fiber into collimated light (parallel light) or to couple external parallel (approximately parallel) light into a single-mode optical fiber. A fiber aligner is usually made of a pigtail and a self-focusing lens with precise positioning. It is a basic device in optical passive devices and is widely used in circulators, optical switches, collimator arrays, MEMS optical switches, passive optical networks, fiber optic rotary connectors, etc. A fiber aligner can help users accurately align the cores of two optical fibers so that optical signals can be transmitted from one optical fiber to another without loss. When the optical fiber is poorly connected, the signal will have a certain loss, which is called insertion loss. The fiber aligner helps ensure that the insertion loss is minimized when the optical fibers are connected, thereby improving the transmission quality of the optical signal. By providing a simple, easy-to-use tool, the fiber aligner can help reduce errors in manual operations and simplify the installation and maintenance of optical fibers.

[0003] However, existing fiber aligners often encounter the following problems during use: In fiber optic docking technology, traditional docking grooves always face an extremely difficult problem that has not yet been properly solved when performing 60-micron optical fiber docking operations, that is, the 60-micron optical fiber is too small and fragile. During the docking process, the optical fiber is extremely prone to alignment deviation and breakage. This problem has long plagued the development of this field. At present, an effective and thorough solution has not been found on the market, resulting in a series of adverse consequences such as signal transmission loss and transmission interruption caused by alignment deviation when docking 60-micron optical fibers, which seriously affects the efficiency and stability of fiber optic docking technology in related application scenarios.

The base 1 is provided with a storage space, and the base 1 is provided with a storage space to provide space for the installation and movement of other components. It is the basic structure of the entire fiber optic aligner, and other components are arranged and work together on it. The left fiber optic clamp seat 2 is mounted on the base 1, and the left fiber optic clamp seat 2 is located on the left side of the cross section of the base 1. The upper pressure cover 3 is hinged to one side of the base 1, and the flat pressure head 4 is installed on the bottom of the upper pressure cover 3. The upper pressure cover 3 can be easily opened and closed by hinge, which is convenient for placing optical fibers. The flat pressure head 4 and the gasket 5 cooperate, and the flat pressure head 4 is pressed down by the rotation of the upper pressure cover 3. When the upper pressure cover 3 is closed, the flat pressure head 4 applies a certain pressure to the optical fiber on the top surface of the left fiber optic clamp seat 2 through the gasket 5, which plays a role in fixing the optical fiber.

[0051] In this embodiment, the gasket 5 is located below the flat pressure head 4, and the gasket 5 is arranged on the top surface of the left optical fiber clamp seat 2. The first guide rib 6 is arranged on both sides of the gasket 5, and the V-shaped grooves 8 on the first guide rib 6 and the second guide rib 7 are both in a straight line. There are two second guide ribs 7, and the two second guide ribs 7 are arranged side by side and parallel on the gasket 5. The two second guide ribs 7 divide the gasket 5 into three sections. The two second guide ribs 7 are used for optical fiber guidance, auxiliary support and avoidance. They are mainly used to place optical fibers with coating layers, which serves the purpose of enhancing the strength of optical fibers. Optical fibers with coating layers are not easy to break. The first guide rib 6 is parallel to the second guide rib 7, and the V-shaped groove 8 is opened on the first guide rib 6 and the second guide rib 7. The docking groove 9 is located between the two guide ribs, and the two ends of the docking groove 9 are connected to the V-shaped groove 8. The diameter of the docking groove 9 is 60 microns.

[0052] Preferably, the left fiber optic pressure plate 10 is placed on the left fiber optic clamp seat 2, and the left fiber optic pressure plate 10 and the left fiber optic clamp seat 2 are magnetically adsorbed and connected via a magnet, the left fiber optic groove 11 is opened on the top surface of the left fiber optic clamp seat 2, the right fiber optic clamp seat 12 is located in the extension direction of one side of the left fiber optic clamp seat 2, the right fiber optic pressure plate 13 is adsorbed and connected to the top surface of the right fiber optic clamp seat 12 via a magnet, the right fiber optic groove 14 is opened on the top surface of the right fiber optic clamp seat 12, the connection by magnet adsorption can be easily opened and closed, the fiber optic groove provides a placement position for the optical fibers on the left and right sides, and the two cooperate to fix the optical fibers on the left and right sides. The limiting cavity 15 is provided at the bottom of the right optical fiber clamp seat 12, the guide rail pad 16 is located in the limiting cavity 15, the linear slide 17 is installed on the guide rail pad 16, the linear slide 17 is slidably connected to the right optical fiber clamp seat 12, the connecting port 18 is located below the bottom surface of the right optical fiber clamp seat 12, and the connecting port 18 is provided on the base 1, one end of the conversion block 19 passes through the connecting port 18 and is connected to the bottom surface of the right optical fiber clamp seat 12, and the main body of the conversion block 19 is located inside the base 1. The limiting cavity 15 provides an installation space for the guide rail pad 16, and the guide rail pad 16 is used to install the linear slide 17. The linear slide 17 is slidably connected to the right optical fiber clamp seat 12. Such a design enables the right optical fiber clamp seat 12 to slide smoothly in a straight line direction, thereby realizing the adjustment of the distance between the left and right optical fiber clamp seats 12 to achieve the purpose of optical fiber docking.

[0053] Preferably, one end of the compression spring 20 is connected to the inner wall of the base 1, the other end of the compression spring 20 is connected to the conversion block 19, the hand wheel 21 is installed in the extension direction of one side of the right optical fiber clamp seat 12, the bottom surface of the hand wheel 21 extends into the base 1, the sliding wheel 22 is sleeved on the bottom surface of the hand wheel 21, and the side wheel surface of the sliding wheel 22 contacts the conversion block 19; the contact surface between the sliding wheel 22 and the conversion block 19 is arc-shaped, and the first transmission rod 23 is installed on the sliding wheel 22; the setting position of the first transmission rod 23 is located at the edge of the sliding wheel 22, the second transmission rod 24 is located in the extension direction of one side of the first transmission rod 23, one side of the tension spring 25 is connected to the second transmission rod 24, and the other side of the tension spring 25 is connected to the second transmission rod 24. The compression spring 20 plays an important resetting role in the process of optical fiber docking. When the conversion block 19 is pushed to translate, the compression spring 20 is squeezed to store energy; after the optical fiber docking is completed, the compression spring 20 releases energy, pushes the conversion block 19 to reset, and drives the right optical fiber clamp seat 12 back to the initial position or the appropriate docking position.

[0054] It should be noted that, when the optical fiber aligner with a guide structure designed by the present invention is used, the upper cover 3 is first opened, and one of the two optical fibers to be docked is placed in the left optical fiber groove 11, and one end of the optical fiber in the left optical fiber groove 11 needs to enter the docking groove 9. The hand wheel 21 is rotated clockwise, and the rotation of the hand wheel 21 will drive the sliding wheel 22, and the rotation of the sliding wheel 22 will drive the second transmission rod 24. Since the second transmission rod 24 is in a non-axial position, the rotation of the sliding wheel 22 will gradually change the position of the second transmission rod 24. When the second transmission rod 24 gradually moves away from the first transmission rod 23, the tension spring 25 will be pulled. Since the sliding wheel 22 has an arc surface, when the most protruding position of the arc surface of the sliding wheel 22 gradually contacts the conversion block 19, the conversion block 19 will be pushed to start translation. At the same time, the movement of the conversion block 19 will squeeze the compression spring 20. The translation of the conversion block 19 will drive the right optical fiber clamp seat 12 to slide on the linear slide rail 17, and the right optical fiber clamp seat 12 will gradually move away from the left optical fiber clamp seat 2. Then put another optical fiber on the right optical fiber clamp seat 12, cover it with the upper pressure cover 3, turn the hand wheel 21 counterclockwise, and the conversion block 19 will gradually reset under the pressure of the compression spring 20 and the resilience of the tension spring 25. The right optical fiber clamp seat 12 is driven to gradually approach the left optical fiber clamp seat 2 until the left and right optical fibers stop moving after docking in the 60um optical fiber V-groove. During the docking process, the V-grooves 8 of the two second guide edges 7 will further provide guidance for the docking of the two optical fibers, and the docking groove 9 in the middle section plays the role of real optical fiber docking, shortening the docking distance and achieving the requirements of temporary docking.

[0055] Although embodiments of the present invention have been shown and described, it will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit of the invention, and the scope of the invention is defined by the appended claims and their equivalents.
