Description

Technical Field

[0001] This utility model relates to the field of optical fiber connectors, and more particularly to an optical fiber connector assembly. Background Technology

[0002] In the field of modern optical communication, fiber optic connector assemblies are key components for achieving reliable connections between optical fibers, and are widely used in data centers, telecommunications networks, industrial control, and many other scenarios. With the continuous development of optical fiber communication technology, the performance and applicability requirements for fiber optic connector assemblies are becoming increasingly stringent, demanding stable operation under different environments and fiber specifications to ensure efficient transmission of optical signals.

[0003] Currently, traditional fiber optic connector assemblies mostly employ fixed-specification clamping components in their structural design, commonly including simple snap-fit ​​or screw-fastening structures. Their technical principle primarily involves fixing the optical fiber within the connector through preset mechanical dimensions and fastening methods. Snap-fit ​​structures achieve fixation through the interaction of slots and blocks, while screw-fastening structures utilize the pressure generated by tightening screws to secure the optical fiber.

[0004] However, these traditional structures, due to their fixed dimensions, are difficult to flexibly adapt to optical fibers of different outer diameters. When encountering optical fibers of special sizes or different types, either a stable connection cannot be achieved, leading to unstable optical signal transmission, signal interruption, or excessive loss; or they cannot be installed at all, greatly limiting the application range of optical fiber connector assemblies. Therefore, an optical fiber connector assembly is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an optical fiber connector assembly, which aims to improve the problem that traditional methods in the prior art cannot flexibly adapt to optical fibers of different sizes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fiber optic connector assembly includes a connector body, a dustproof component provided on the side wall of the connector body, a fixing sleeve provided on the side wall of the connector body, and a limit component provided inside the connector body.

[0008] The limiting component includes a clamping plate, a connecting block is fixedly connected to the side wall of the connector body, a fixing ring is fixedly connected inside the connector body, a sleeve is fixedly connected inside the fixing ring, a connecting rod is slidably connected inside the sleeve, a spring is provided inside the sleeve, the side wall of the clamping plate is fixedly connected to the side wall of the connecting rod, a rubber pad is fixedly connected to the side wall of the clamping plate, and an elastic band is fixedly connected between the clamping plates.

[0009] As a further description of the above technical solution:

[0010] The dustproof component includes a dustproof cover, which is internally slidably connected to the side wall of the connector body.

[0011] As a further description of the above technical solution:

[0012] A sealing gasket is fixedly connected inside the dust cover, and the side wall of the sealing gasket is in contact with the side wall of the connector body.

[0013] As a further description of the above technical solution:

[0014] The connector body has a connecting strap on its side wall, and a fixing block is fixedly connected to one end of the connecting strap.

[0015] As a further description of the above technical solution:

[0016] The side wall of the fixing block is fixedly connected to the side wall of the dust cover, and the other end of the connecting strip is fixedly connected to a rotating rod.

[0017] As a further description of the above technical solution:

[0018] A fixing frame is fixedly connected to the side wall of the connector body, and the side wall of the rotating rod is rotatably connected inside the fixing frame.

[0019] As a further description of the above technical solution:

[0020] The fixing sleeve is threadedly connected to the side wall of the connecting block.

[0021] As a further description of the above technical solution:

[0022] One end of the spring is fixedly connected to the inside of the sleeve, and the other end of the spring is fixedly connected to the side wall of the connecting rod.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, when the optical fiber is inserted into the connector body, the clamping plate is squeezed, causing the connecting rod to slide inside the sleeve. The spring and elastic band deform. After the optical fiber is in place, the spring and elastic band reset, fixing the optical fiber. The rubber pad on the clamping plate increases friction without damaging the optical fiber, solving the problem that the traditional method cannot flexibly adapt to optical fibers of different sizes. The above technical solution improves the universality and stability of optical fiber connection.

[0025] 2. In this utility model, when the connector body is not in use, the dust cover is rotated, the rotating rod rotates in the fixed frame, the dust cover covers the port, and its internal sealing gasket fits against the side wall of the connector body to prevent dust and moisture from entering and protect the internal optical components. This solves the problem that the traditional dust prevention method relies only on a simple dust cap, which has poor sealing performance and is easy to lose. The above technical solution improves the dust protection effect of the internal optical components of the fiber optic connector. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 - Figure 3This utility model provides an embodiment of an optical fiber connector assembly, comprising a connector body 1, a dustproof component on the side wall of the connector body 1, a fixing sleeve 2 on the side wall of the connector body 1, and a limiting component inside the connector body 1; the limiting component includes a clamping plate 8, a connecting block 3 fixedly connected to the side wall of the connector body 1, a fixing ring 4 fixedly connected inside the connector body 1, a sleeve 5 fixedly connected inside the fixing ring 4, a connecting rod 6 slidably connected inside the sleeve 5, and a spring 7 inside the sleeve 5. The spring 7 generates elastic force to push the connecting rod 6 and the clamping plate 8 connected thereto, enabling the clamping plate 8 to adaptively clamp optical fibers of different thicknesses. The side wall of the clamping plate 8 is fixedly connected to the side wall of the connecting rod 6. A rubber pad 9 is fixedly connected to the side wall of the clamping plate 8. The rubber pad 9 can increase the friction between the clamping plate 8 and the optical fiber. It is soft and will not damage the optical fiber. At the same time, it can better adapt to the surface shape of the optical fiber and improve the clamping stability. An elastic band 10 is fixedly connected between the clamping plates 8. The elastic band 10 plays an auxiliary reset role. When the optical fiber is inserted or removed, it helps the clamping plate 8 to return to the appropriate position. At the same time, it can also maintain the clamping force of the clamping plate 8 on the optical fiber to a certain extent. The fixing sleeve 2 is threadedly connected to the side wall of the connecting block 3. One end of the spring 7 is fixedly connected to the inside of the sleeve 5, and the other end of the spring 7 is fixedly connected to the side wall of the connecting rod 6.

[0034] Reference Figure 1 and Figure 4 The dustproof component includes a dust cover 11, which covers the port of the connector body 1 when it is not in use, preventing dust, moisture, and other contaminants from entering the interior of the connector body 1. The dust cover 11 is slidably connected to the side wall of the connector body 1, and a sealing gasket 12 is fixedly connected inside the dust cover 11. The side wall of the sealing gasket 12 fits against the side wall of the connector body 1, and the sealing gasket 12 enhances the seal between the dust cover 11 and the connector body 1, preventing fine particles such as dust from entering. The dust cover 11 enters through the gap between the connector body 1 and the dust cover 11. A connecting strap 13 is provided on the side wall of the connector body 1. The connecting strap 13 is used to connect the dust cover 11 and the connector body 1 to prevent the dust cover 11 from being lost. A fixing block 14 is fixedly connected to one end of the connecting strap 13. The side wall of the fixing block 14 is fixedly connected to the side wall of the dust cover 11. A rotating rod 15 is fixedly connected to the other end of the connecting strap 13. A fixing frame 16 is fixedly connected to the side wall of the connector body 1. The side wall of the rotating rod 15 is rotatably connected to the inside of the fixing frame 16.

[0035] Working principle: When the optical fiber is inserted into the connector body 1, the optical fiber contacts the clamp 8 and applies pressure, causing the clamp 8 to push the connecting rod 6 to slide in the sleeve 5. During this process, the spring 7 is compressed and deformed. At the same time, as the clamp 8 moves outward, the elastic band 10 is stretched and deformed. When the optical fiber is inserted into the appropriate position, the spring 7 and the elastic band 10 return to their original shape. The force they generate restricts the optical fiber and fixes it in the connector body 1. Meanwhile, the rubber pad 9 on the clamp 8 increases the friction between the optical fiber and the optical fiber, and because of its soft texture, it will not damage the optical fiber.

[0036] When the connector body 1 is not in use, rotate the dust cover 11 so that the rotating rod 15 rotates within the fixing frame 16, thereby covering the port of the connector body 1 with the dust cover 11. At this time, the sealing gasket 12 inside the dust cover 11 is tightly fitted with the side wall of the connector body 1, effectively preventing dust, moisture and other contaminants from entering the interior of the connector body 1, thus protecting the cleanliness of the internal optical components.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
