Description

Technical Field

[0001] This utility model belongs to the field of optical fiber connector technology, and specifically relates to an optical fiber connector with a connector sealing structure. Background Technology

[0002] In the construction and operation of fiber optic communication systems, fiber optic connectors, as core connecting components, primarily function to achieve efficient connection between fiber optic cables and related equipment such as optical modules and optical switches through precise plugging, thereby ensuring stable transmission of optical signals between different components. However, most current fiber optic connectors often have a critical design flaw at the connection end after being connected to the equipment: the lack of a dedicated sealing structure.

[0003] This structural deficiency may not immediately manifest as a problem in a dry, clean environment, but it will expose serious hidden dangers in humid environments such as outdoor equipment boxes, underground pipelines, and industrial workshops. Moisture, condensation, and even trace amounts of liquid in humid environments can slowly seep in through the gaps between the connector and the equipment. Initially, a thin film of water may form on the metal contacts or fiber optic end faces. Over time, the water stains will gradually erode the coating on the contact surfaces, leading to oxidation and corrosion of the metal components. For the fiber optic end faces, impurities contained in the water stains may also adhere to the surface, increasing optical signal transmission loss and potentially causing micro-cracks in the precision ceramic ferrule of the fiber optic connector or the quartz fiber itself under long-term immersion in moisture, thus disrupting the optical signal transmission path. Utility Model Content

[0004] The purpose of this invention is to provide an optical fiber connector with a sealing structure, designed to address the issue that moisture, condensation, and even trace amounts of liquid in humid environments can slowly seep into the connector through the gaps between the connector and the equipment. Initially, a thin film of water may form only on the metal contacts or fiber end face at the connection point. However, over time, the water stains will gradually erode the coating on the contact surface, leading to oxidation and corrosion of the metal components.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an optical fiber connector with a connector sealing structure, comprising an optical fiber, one end of which is installed inside the connector end, and a side block is fixedly bonded to the outer walls on both sides of the connector insertion end.

[0006] Each of the side blocks has a compression spring installed inside. One end of the compression spring is glued to the outer wall of one side ear. One side outer wall of the side ear is integrally installed on the outer wall of the movable frame. A sealing gasket is glued to one side outer wall of the movable frame. The movable frame and the sealing gasket are movably fitted onto the outer wall of the connector plug end.

[0007] In order to enable the compression spring to push the movable frame to move towards the connector plug end during use, as a fiber optic connector with a connector sealing structure of this utility model, preferably, the side block has an inner cavity, and a guide strip is fixedly installed on the outer walls of both sides of the inner cavity. An end block is integrally installed on the outer wall of the guide strip near the opening end of the inner cavity.

[0008] One end of the compression spring is movably installed inside the side block through the inner cavity. The end of the compression spring inside the side block is fixedly connected to one side of the outer wall of the movable disk. A rectangular notch is opened on the outer wall on both sides of the horizontal line of the movable disk. The movable disk is slidably connected between the two guide bars through the rectangular notch.

[0009] To reduce friction during adjustment of the adjusting bolt and thus improve the smoothness of adjustment, as a fiber optic connector with a joint sealing structure of this utility model, preferably, a semi-circular block is fixedly installed on the outer wall of the movable disc away from the compression spring. The outer wall of one side of the semi-circular block is movably connected to one end of the adjusting bolt. The adjusting bolt passes through the inner wall of the side block from one end of the side block. The connection end between the adjusting bolt and the side block is a threaded structure.

[0010] One end of the adjusting bolt has a semi-circular opening, and the adjusting bolt and one end of the semi-circular block form a positioning and movable docking structure through the semi-circular opening.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] When the connector is aligned with the router's port, adjust the adjusting bolt further into the inner cavity. As the adjusting bolt moves inward, it pushes the movable plate, which in turn moves the compression spring. This compression spring, through the movable frame, moves the sealing gasket towards the connection point between the connector and the router. Ultimately, the sealing gasket presses against the opening at the connection point, thus sealing the connection between the connector and the router during use and preventing water from entering.

[0019] 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.

[0020] Please see Figure 1-4 The present invention provides the following technical solution: an optical fiber connector with a connector sealing structure, including an optical fiber 1, one end of the optical fiber 1 is installed inside one end of a connector 2, and a side block 3 is fixedly bonded to the outer walls on both sides of the plug end of the connector 2.

[0021] In use, connect one end of fiber optic cable 1 to the end of connector 2. After connection, plug one end of connector 2 into the port on the router. This allows external network data to be collected by the router via fiber optic cable 1 and connector 2, and then the router distributes the network information.

[0022] Each side block 3 has a compression spring 4 installed inside. One end of the compression spring 4 is glued to the outer wall of one end of the side ear 5. One side of the outer wall of the side ear 5 is integrally installed on the outer wall of the movable frame 6. A sealing gasket 7 is glued to one side of the outer wall of the movable frame 6. The movable frame 6 and the sealing gasket 7 are movably fitted onto the outer wall of the insertion end of the connector 2.

[0023] The sealing gasket 7 is interference-fitted onto the outer wall of the connector 2. During use, the compressive force of the two compression springs 4 is greater than the interference friction between the sealing gasket 7 and the connector 2, thereby allowing the sealing gasket 7 to move smoothly on the outer wall of the connector 2 during use.

[0024] Preferably, the side block 3 has an inner cavity 31 inside, and a guide strip 32 is fixedly installed on the outer walls of both sides of the inner cavity 31. An end block 33 is integrally installed on the outer wall of the guide strip 32 near the opening end of the inner cavity 31.

[0025] One end of the compression spring 4 is movably installed inside the side block 3 through the inner cavity 31. The end of the compression spring 4 located inside the side block 3 is fixedly connected to one side of the outer wall of the movable disk 41. A rectangular notch is opened on the outer wall on both sides of the horizontal line of the movable disk 41. The movable disk 41 is slidably connected between the two guide bars 32 through the rectangular notch.

[0026] In practical use, the movable disk 41 moves along the trajectory of the two guide bars 32. When the movable disk 41 moves to the end of the guide bars 32, the end block 33 at the end of the guide bars 32 will obstruct the movable disk 41, thereby preventing the movable disk 41 from detaching from the two guide bars 32.

[0027] Preferably, a semicircular block 42 is fixedly installed on the outer wall of the movable disc 41 away from the compression spring 4. One side of the outer wall of the semicircular block 42 is movably connected to one end of the adjusting bolt 43. The adjusting bolt 43 passes through the inner wall of the side block 3 from one end. The connection end between the adjusting bolt 43 and the side block 3 is a threaded structure.

[0028] One end of the adjusting bolt 43 has a semi-circular opening 44, and the adjusting bolt 43 and one end of the semi-circular block 42 form a positioning and movable docking structure through the semi-circular opening 44.

[0029] Rotating the adjusting bolt 43 causes it to move inwards through the threaded structure between it and the side block 3. As the side block 3 rotates and moves laterally, it rotates and rubs against the outer wall of the semi-circular block 42 through the semi-circular opening 44. This allows the adjusting bolt 43 to smoothly push the movable disc 41 within the inner cavity 31. The movement of the movable disc 41 then pushes the compression spring 4, which in turn moves the movable frame 6, causing the sealing gasket 7 to move.

[0030] Working principle: When connector 2 is connected to the router's port, the adjusting bolt 43 is adjusted into the inner cavity 31. When the adjusting bolt 43 moves into the inner cavity 31, it pushes the movable plate 41 to move, and the movable plate 41 moves, which in turn drives the compression spring 4 to move.

[0031] By compressing the spring 4, the sealing gasket 7 can be moved towards the mating end of the connector 2 and the router via the movable frame 6. Finally, the sealing gasket 7 will be pressed against the opening of the mating end of the connector 2 and the router. Thus, during use, the mating end of the connector 2 and the router can be sealed through the above structure to prevent water stains from entering the mating end of the connector 2 and the router.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
