Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical fiber docking technology, and more specifically, to an optical fiber docking connector. Background Technology
[0002] With the rapid development of fiber optic communication technology, fiber optics, as a key medium for information transmission, play a decisive role in the performance of the entire communication system due to the accuracy and stability of their connections. As a core component for achieving reliable fiber optic connections, the design quality of fiber optic connectors directly affects the transmission quality of fiber optic signals.
[0003] Currently, in the market, the conventional approach to fiber optic connector technology to reduce the problem of excessive bending of the fiber during insertion is to use a simple sleeve structure to guide the fiber insertion. However, this traditional method has many limitations.
[0004] On the one hand, the guiding accuracy of the sleeve structure is limited. During fiber insertion, due to the lack of precise dimensional transition design, the fiber is still prone to large-angle bending at local locations, leading to increased optical signal transmission loss inside the fiber and potentially causing signal interruption, severely affecting the reliability and stability of communication. On the other hand, the existing guiding structure has insufficient ability to limit the fiber's position. When the connector is subjected to external vibration or slight impact, the fiber is prone to relative displacement inside the connector, causing misalignment of the mating position and resulting in fiber mating failure, increasing the cost and workload of fiber maintenance and re-mating.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0025] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.
[0026] Please see Figure 1-6 The present invention provides the following technical solution:
[0027] Example 1: In order to reduce the problem of excessive bending of optical fibers during insertion.
[0028] The fiber optic connector includes a first snap-fit sleeve 1 and a quick-connect mechanism 2. The quick-connect mechanism 2 is slidably disposed beside the first snap-fit sleeve 1. The quick-connect mechanism 2 includes a connector body 21, snap-fit parts 22, and a sliding unit 23. The connector body 21 is slidably disposed beside the first snap-fit sleeve 1, and the first snap-fit sleeve 1 has a mounting groove 211 for inserting the connector body 21. The snap-fit parts 22 have a pair and are respectively disposed on the top of the connector body 21. The first snap-fit sleeve 1 has snap-fit grooves on both sides that are interference fit with the pair of snap-fit parts 22. When the snap-fit parts 22 move, they can abut against the snap-fit grooves. The connector body 21 has an installation chamber 212 inside for restricting the passage of optical fibers. The size of the installation chamber 212 gradually decreases from the optical fiber insertion point. When the optical fiber is inserted, it can gradually abut against the installation chamber 212. The sliding unit 23 is slidably disposed beside the connector body 21 and is used to clamp the optical fiber and slide.
[0029] The operator first inserts the optical fiber into the mounting slot 211 beside the first retaining sleeve 1, and then moves the first retaining sleeve 1 along the outside of the optical fiber. In this state, the optical fiber can be further inserted into the mounting chamber 212 opened in the connector body 21. During this insertion process, the mounting chamber 212 opened inside the connector body 21 can gradually guide the optical fiber, thereby limiting the insertion of the optical fiber. As the size of the mounting chamber 212 gradually decreases from the optical fiber insertion extension, the optical fiber will be gradually restricted by the mounting chamber 212 during the insertion process until the optical fiber stops moving when it is inserted into the sliding unit 23. Then, the sliding unit 23 slides beside the connector body 21, which can realize the rapid docking and pulling action of the optical fiber. This prevents the optical fiber from tilting excessively when connected to the connector body 21, ensuring stable docking of the optical fiber.
[0030] See Figures 2-4 The quick docking mechanism 2 also includes a flipping part 24; the flipping part 24 is rotatably disposed on the side of the connector body 21, and when the flipping part 24 is flipped, it can coincide with the end face of the connector body 21.
[0031] When the optical fiber is inserted into the connector body 21 and located beside the sliding unit 23, the operator opens the flip part 24. When opened, the position of the optical fiber inserted into the sliding unit 23 can be observed. In this embodiment, it should be noted that the operator should open the flip part 24 when the optical fiber is inserted into the connector body 21, so that the operator can easily observe the insertion of the optical fiber.
[0032] See Figures 3-6The connector body 21 has a horizontal limiting groove on its side for limiting the sliding unit 23 to slide. The sliding unit 23 can move along the horizontal limiting groove, and the middle of the sliding unit 23 has a circular opening for the optical fiber to pass through.
[0033] In this embodiment, the circular opening of the sliding unit 23 is smaller than the diameter of the mounting chamber 212. Therefore, when light is inserted into the interior of the sliding unit 23, the operator can move the sliding unit 23 along the horizontal limiting groove away from the connector body 21. This allows the slightly tilted optical fiber to continue moving under the action of the sliding unit 23. It should be noted that in this embodiment, during the process of the optical fiber being moved and pulled by the sliding unit 23, the operator needs to move the optical fiber synchronously so that the side of the optical fiber and the sliding unit 23 are always in a slightly tilted state.
[0034] See Figures 3-6 The quick docking mechanism 2 also includes a limiting part 25; the limiting part 25 is disposed on the side of the connector body 21, the limiting part 25 is located on the side of the sliding unit 23, and the contact end face of the limiting part 25 and the sliding unit 23 is provided with a chamfered structure, and the limiting part 25 can be screwed into the inner wall of the connector body 21 to abut against it.
[0035] Until the sliding unit 23 slides to the position of the limiting part 25, the operator closes the flip part 24. After closing, the operator pushes the sliding unit 23 again to slide away from the connector body 21 until the sliding unit 23 contacts the chamfered structure on the end face of the limiting part 25. In this embodiment, the end face of the sliding unit 23 is provided with a pressure groove that contacts the end face of the limiting part 25. When the end face of the sliding unit 23 contacts the end face of the limiting part 25, the chamfered structure of the limiting part 25 can contact and slightly squeeze the pressure groove of the sliding unit 23, so that the optical fiber can be slightly abutted and squeezed and fixed by the inner wall of the sliding unit 23, thereby realizing the rapid sliding installation and docking of the optical fiber and improving the docking stability of the optical fiber.
[0036] See Figures 3-6 The limiting part 25 is a hollow structure, and the diameter of the hollow structure of the limiting part 25 is smaller than that of the circular opening. The optical fiber can pass through the hollow structure of the limiting part 25 and is in contact with the end face of the hollow structure.
[0037] In this embodiment, the optical fiber needs to pass through the first snap-fit sleeve 1, the connector body 21, the sliding unit 23 and the limiting part 25 before the raised optical fiber returns to straight, completing the rapid connection and installation of the optical fiber.
[0038] See Figures 3-6The quick docking mechanism 2 also includes a connector 26; the connector 26 is rotatably disposed on the side of the connector body 21, and a circular channel for optical fiber to pass through is opened in the middle of the connector 26.
[0039] In this embodiment, when the optical fiber is fixed by the sliding unit 23 and the limiting part 25, the other end of the optical fiber should be outside the connector 26 in this state.
[0040] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
