[0002] An optical fiber connector is a device for detachably connecting optical fibers. It precisely docks the two end faces of the optical fibers so that the optical energy output from the transmitting optical fiber can be coupled into the receiving optical fiber to the maximum extent, and the influence on the system caused by its insertion into the optical link is minimized. This is the basic requirement for an optical fiber connector.

[0003] Traditional optical fiber connectors have some disadvantages. For an optical fiber connector, its front frame sleeve is formed by plastic injection molding, the rear frame sleeve part and the metal part are formed by insert injection molding, and the front and rear frame sleeve parts are connected by a snap structure. However, the snap part is relatively small. During docking, the operator needs to press the snap for docking, but the snap part is small, which makes it difficult for the operator to press the snap, and thus the operator cannot quickly install the optical fiber plug.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] To make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] As Figures 1-5 shown, a quick-insert connector for rapid installation of optical fibers includes an installation ring 1. One end of the installation ring 1 is fixedly connected to a connection ring 2. The outer side of the connection ring 2 is in damping sliding connection with a limiting sleeve 3. One side of the inner side of the limiting sleeve 3 close to the connection ring 2 is fixedly connected to a limiting ring 4. A limiting hole 5 is opened at the upper end of the installation ring 1. A limiting ball 6 is movably connected inside the limiting hole 5. The inner side of the installation ring 1 is movably connected to a docking ring 7. A limiting groove 8 is opened on the outer side of the docking ring 7. One end of the docking ring 7 is fixedly connected to a docking head 9. A sliding groove 10 is opened at the upper end of the docking head 9. The other end of the docking ring 7 is fixedly connected to an installation seat 11. The inner top of the connection ring 2 is fixedly connected to a clamping block 12. A sealing ring 16 is inlaid and installed on the inner wall of the inner side of the installation ring 1. The outer side of the installation seat 11 is fixedly connected to a connection frame 17. The upper end of the connection frame 17 is fixedly connected to a plugging sleeve 18.

[0022] In this embodiment, the outer diameter of the installation ring 1 is smaller than the outer diameter of the connection ring 2. The inner side of the limiting ring 4 is in sliding connection with the outer side of the installation ring 1. The limiting ring 4 is in contact with the limiting ball 6. The outer side of the limiting ball 6 near the lower side of the limiting hole 5 is in movable connection with the inner side of the limiting groove 8. The outer side of the clamping block 12 is in sliding connection with the inner side of the sliding groove 10. The axis lines of the installation ring 1, the connection ring 2, the limiting sleeve 3, the limiting ring 4, the docking ring 7, and the docking head 9 are located on the same straight line.

[0023] Specifically, slide the limiting sleeve 3 towards the connection ring 2, and then put the installation ring 1 on the outer side of the docking ring 7. Then, push the limiting sleeve 3 in the reverse direction, so that the limiting sleeve 3 drives the limiting ring 4 to move, and the limiting ring 4 moves to the corresponding limiting hole 5, so that the limiting ring 4 contacts the limiting ball 6, and then the limiting ring 4 can limit the limiting ball 6 inside the limiting hole 5 and the limiting groove 8, so that the limiting ball 6 clamps the docking ring 7 inside the installation ring 1. By pulling the limiting sleeve 3 and moving it towards the connection ring 2, then putting the installation ring 1 on the outer side of the docking ring 7, and then pushing the limiting sleeve 3 in the reverse direction to make the limiting ring 4 move to the corresponding limiting hole 5, the purpose of easily limiting the limiting ball 6 inside the limiting hole 5 and the limiting groove 8 can be achieved, so that the limiting ball 6 can easily clamp the docking ring 7 inside the installation ring 1, realizing the effect of rapid installation and docking of optical fibers.

[0024] In this embodiment, the other end of the connection ring 2 is fixedly connected to a threaded head 13. The other end of the threaded head 13 is fixedly connected to a gasket ring 14. The outer side of the threaded head 13 is threadedly connected to a fastening sleeve 15. The axis lines of the connection ring 2, the threaded head 13, the gasket ring 14, and the fastening sleeve 15 are located on the same straight line.

[0025] Specifically, by screwing the fastening sleeve 15 onto the outside of the threaded head 13, such that the fastening sleeve 15 is sleeved on the outside of the gasket ring 14, the fastening sleeve 15 clamps the optical fiber through the gasket ring 14.

[0026] Working principle:

[0027] During use, first install the mounting base 11 at the designated position, then slide the limiting sleeve 3 towards the side of the connecting ring 2, and sleeve the mounting ring 1 on the outside of the docking ring 7, and make the sealing ring 16 stuck on the outside of the optical fiber, such that a sealing effect is formed between the mounting ring 1 and the optical fiber through the sealing ring 16, and the clamping block 12 is stuck inside the sliding groove 10. At the same time, when the mounting ring 1 is sleeved on the outside of the docking ring 7, the docking ring 7 pushes the limiting ball 6 upwards, and when the clamping block 12 is completely stuck inside the sliding groove 10, the limiting ball 6 slides down into the inside of the limiting groove 8 under the action of gravity. Then, push the limiting sleeve 3 in the reverse direction, such that the limiting sleeve 3 drives the limiting ring 4 to move, and the limiting ring 4 moves to the corresponding limiting hole 5, so that the limiting ring 4 contacts the limiting ball 6, and the limiting ring 4 can limit the limiting ball 6 inside the limiting hole 5 and the limiting groove 8, so that the limiting ball 6 clamps the docking ring 7 inside the mounting ring 1. If the plugging sleeve 18 is inserted into the inside of the mounting base 11, the mounting base 11 is plugged by the plugging sleeve 18, thereby preventing foreign objects from entering the mounting base 11 and achieving a dust-proof effect. By pulling the limiting sleeve 3 to move towards the side of the connecting ring 2, then sleeving the mounting ring 1 on the outside of the docking ring 7, and then pushing the limiting sleeve 3 in the reverse direction to make the limiting ring 4 move to the corresponding limiting hole 5, the purpose of facilitating the limiting ring 4 to limit the limiting ball 6 inside the limiting hole 5 and the limiting groove 8 can be achieved, so as to facilitate the limiting ball 6 to clamp the docking ring 7 inside the mounting ring 1 and achieve the effect of quickly installing and docking the optical fiber.
