Description

Technical Field

[0001] This utility model relates to the field of optical fiber connector technology, specifically to a detachable optical fiber connector. Background Technology

[0002] Fiber optic connectors are passive devices used to enable detachable connections between optical fibers and between optical fibers and optical devices. Their core function is to align the fiber core to ensure low-loss transmission of optical signals. They are widely used in communication networks, data centers, broadcasting and television, industrial testing and other fields, and are an indispensable basic component in optical communication systems. Fiber optic connectors are also available in various models, such as LC, FC, SC and ST.

[0003] Most LC fiber optic connectors, after assembly, have their outer shell secured by fixed protrusions engaging with the slot. While this makes installation convenient, it hinders disassembly, as the protrusions, once engaged with the slot, are difficult to detach. This makes it inconvenient to separate the connector, making it difficult to replace the ferrule if it is damaged, significantly reducing the device's practicality. To address this issue, we provide a detachable fiber optic connector. Utility Model Content

[0004] The purpose of this invention is to provide a detachable fiber optic connector, which solves the problem in the prior art where the outer shell is not easy to disassemble, making it inconvenient to separate the connector and thus making it inconvenient to replace the ferrule individually.

[0005] This utility model provides the following technical solution: a detachable optical fiber connector, comprising an optical fiber body and a tail sleeve, wherein a limiting sleeve is installed at one end of the tail sleeve, and both the tail sleeve and the limiting sleeve are sleeved on the surface of the optical fiber body, a ferrule assembly is installed at one end of the optical fiber body, a housing is sleeved on the surface of the limiting sleeve, the ferrule assembly is disposed inside the housing, and a splitting assembly for limiting and fixing the housing is provided on both sides of the limiting sleeve, and a protective assembly for protecting the splitting assembly is provided at both ends of the housing.

[0006] As a preferred embodiment of the above technical solution, the ferrule assembly includes a ferrule body, a sleeve is fitted on one side of the ferrule body, one stripped end of the optical fiber body passes through the sleeve and is inserted into the ferrule body and cured with glue, a spring is fitted on the surface of the sleeve, the spring and the sleeve are both inserted into a limiting sleeve, and the end of the ferrule body away from the sleeve extends to the outside of the outer shell.

[0007] The above technical solution enables the fiber body to be fixed at the center of the ferrule body, ensuring that the end face of the fiber body is flush with the end face of the ferrule body. This facilitates precise alignment of the fiber body end face and ensures efficient transmission of optical signals.

[0008] As a preferred embodiment of the above technical solution, each set of the disassembly components includes a slide groove, each set of slide grooves is opened at the side end of the limiting sleeve, each set of slide grooves is equipped with a second spring, each set of slide grooves is slidably installed with a limiting rod at the opening, and the inner end of the limiting rod is connected to the second spring. The two ends of the outer shell are provided with limiting holes at positions corresponding to the two sets of limiting rods, and each set of limiting rods is inserted into the limiting hole.

[0009] The above technical solution makes it easier for the elastic limiting rod to detach from the limiting hole, which makes the outer shell not only easy to install but also easy to disassemble. Then, pull the outer shell until it separates from the limiting sleeve, thus realizing the separate assembly and disassembly of the device, which greatly increases the practicality of the device.

[0010] As a preferred embodiment of the above technical solution, the outer diameter of each set of limiting rods is adapted to the inner diameter of the limiting hole.

[0011] The above technical solution makes it less likely for the limiting rod to wobble within the limiting hole, thus making the outer casing more securely installed.

[0012] As a preferred embodiment of the above technical solution, each set of protective components includes two sets of fixing rods. Each set of two fixing rods is installed on both sides of one end of the outer casing where a limiting hole is opened. Each set of two fixing rods has a movable groove at the end away from the outer casing. Each set of two fixing rods has a protective plate at the end away from the outer casing. Each set of protective plates has sliders connected to both sides of the end near the fixing rod. Each set of sliders is slidably installed in the movable groove.

[0013] The above technical solution can protect the limit rod, better prevent accidental contact with the limit rod, and thus reduce the risk of affecting the stability of the assembly.

[0014] As a preferred embodiment of the above technical solution, each set of protective plates near the outer shell has a gap between it and the outer end of the limiting rod.

[0015] The above technical solution makes it less likely for the protective plate to touch the limit rod when it slides.

[0016] As a preferred embodiment of the above technical solution, each set of protective plates has convex strips connected at equal intervals at the end away from the outer shell.

[0017] The above technical solution increases the friction between the material and the protective plate, thereby improving the sliding motion of the protective plate.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This invention, by setting a detachable component, makes it easier for the elastic limiting rod to detach from the limiting hole. This makes the outer shell not only easy to install but also easy to disassemble. Then, by pulling the outer shell until it separates from the limiting sleeve, the device can be disassembled and reassembled separately, allowing for individual replacement of the insert body, which saves costs. In addition, by setting a protective component, the limiting rod can be protected, better preventing accidental contact with the limiting rod and thus not easily affecting the stability of the assembly, greatly increasing the practicality of the device.

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] like Figures 1-5As shown, this utility model provides a technical solution: a detachable optical fiber connector, including an optical fiber body 1 and a tail sleeve 2. A limiting sleeve 21 is installed at one end of the tail sleeve 2. Both the tail sleeve 2 and the limiting sleeve 21 are fitted onto the surface of the optical fiber body 1. A ferrule assembly 3 is installed at one end of the optical fiber body 1. A housing 22 is fitted onto the surface of the limiting sleeve 21. The ferrule assembly 3 is disposed inside the housing 22. The ferrule assembly 3 includes a ferrule body 31. A sleeve 32 is fitted onto one side of the ferrule body 31. One stripped end of the optical fiber body 1 passes through the sleeve 32 and is inserted into the ferrule body 31 and cured with glue. A spring 33 is fitted onto the surface of the sleeve 32. Both the spring 33 and the sleeve 32 are inserted into the limiting sleeve 21. The end of the ferrule body 31 away from the sleeve 32 extends to the outside of the housing 22. This design fixes the optical fiber body 1 at the center of the ferrule body 31, ensuring that the end face of the optical fiber body 1 is flush with the end face of the ferrule body 31, making it easier to accurately align the end face of the optical fiber body 1 and ensure efficient transmission of optical signals.

[0028] As one implementation method in this embodiment, such as Figure 3 and Figure 4 As shown, both sides of the limiting sleeve 21 are provided with splitting components 4 for limiting and fixing the outer shell 22. Each splitting component 4 includes a sliding groove 41, which is opened at the side end of the limiting sleeve 21. A second spring 42 is installed inside the sliding groove 41. A limiting rod 43 is slidably installed at the opening of each sliding groove 41, and the inner end of the limiting rod 43 is connected to the second spring 42. Limiting holes 23 are opened at both ends of the outer shell 22 at positions corresponding to the two sets of limiting rods 43. Each set of limiting rods 43 is inserted into the limiting hole 23. This structure allows the two sets of limiting rods 43 to be pressed simultaneously, so that... The two sets of limiting rods 43 are pushed into the slide groove 41 to compress the second spring 42, which releases the limiting fixation on the outer shell 22, making it easier for the elastic limiting rods 43 to detach from the limiting hole 23. This makes the outer shell 22 easier to install and disassemble. Then, pull the outer shell 22 until it separates from the limiting sleeve 21. This allows the device to be disassembled and reassembled, greatly increasing its practicality. The outer diameter of each set of limiting rods 43 is matched with the inner diameter of the limiting hole 23, making it less likely for the limiting rods 43 to wobble in the limiting hole 23, thus making the installation of the outer shell 22 more stable.

[0029] It should be noted that the fiber body 1, tail sleeve 2, limiting sleeve 21, outer shell 22, ferrule body 31, sleeve 32 and spring 33 are all the main structures of existing fiber optic connectors, so the specific assembly method and function are not explained in detail.

[0030] As one implementation method in this embodiment, such as Figure 4 and Figure 5As shown, both ends of the outer casing 22 are provided with protective components 5 for protecting the disassembly assembly 4. Each set of protective components 5 includes two sets of fixing rods 51. Each set of two fixing rods 51 is installed on both sides of the end of the outer casing 22 where the limiting hole 23 is opened. Each set of two fixing rods 51 has a movable groove 52 at the end away from the outer casing 22. Each set of two fixing rods 51 is provided with a protective plate 53 at the end away from the outer casing 22. Each set of protective plates 53 has sliders 54 connected to both sides of the end near the fixing rods 51. Each set of sliders 54 is slidably installed in the movable groove 52. This structure allows the protective plate 53 to be pushed to move... The slider 54 slides within the movable groove 52 until it moves to block the limiting rod 43, thus protecting the limiting rod 43 and preventing accidental contact with it, thereby minimizing impact on assembly stability. Each set of protective plates 53 has a gap between its outer end and the outer end of the limiting rod 43 near the outer shell 22, making it less likely for the protective plate 53 to touch the limiting rod 43 when sliding. Each set of protective plates 53 has equidistant protrusions 55 at the end away from the outer shell 22, increasing the friction with the protective plate 53 and thus better propelling it to slide.

[0031] Working principle: To disassemble the device, simply push the two sets of protective plates 53 to move the slider 54 in the movable groove 52 until the protective plates 53 move to one side of the two sets of fixed rods 51 and expose the limiting rods 43. Then, press the two sets of limiting rods 43 at the same time to push them into the sliding groove 41 to compress the second spring 42. This will release the limiting fixation on the outer shell 22, making it easier for the elastic limiting rods 43 to detach from the limiting hole 23 and making disassembly easier. Then, pull the outer shell 22 until it separates from the limiting sleeve 21. This will disassemble the device and greatly increase its practicality.

[0032] Alternatively, if the ferrule body 31 needs to be replaced, simply remove the outer casing 22, then push the limiting sleeve 21 and the tail sleeve 2 to slide along the surface of the fiber body 1 and away from the ferrule body 31. At the same time, move the spring 33 away from the ferrule body 31. Then, cut off the ferrule body 31, sleeve 32, and fiber body 1 that are fixed together. Then, peel off a new section of fiber body 1, pass this section of fiber body 1 through the new sleeve 32, and insert it into the new ferrule body 31. Finally, re-cure with glue to replace the ferrule. The main body 31 and sleeve 32 are assembled with spring 33, limiting sleeve 21 and tail sleeve 2. Finally, the outer shell 22 is put on. When putting it on, you can first press the two sets of limiting rods 43 and push the two sets of limiting rods 43 into the slide groove 41 to compress spring 42. At this time, the outer shell 22 can be completely put on the surface of the limiting sleeve 21 until the outer shell 22 drives the limiting hole 23 to correspond with the limiting rod 43. The limiting rod 43 can then be pushed into the limiting hole 23 by the spring force of spring 42 to limit and fix the outer shell 22, thus completing the assembly of the device.

[0033] Finally, push the two sets of protective plates 53 again to drive the slider 54 to slide in the movable groove 52 until the slider 54 moves to block the limit rod 43. This can protect the limit rod 43 and better prevent accidental contact with the limit rod 43, thus making it less likely to affect the stability of the assembly.

[0034] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
