Description

Technical Field

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

[0002] FC type fiber optic connectors are generally connected to FC square fiber optic flange coupling adapter connectors. Fiber optic connectors (also known as patch cords) are cables with connector plugs at both ends of the optical fiber, used to achieve active optical path connections. The connection between fiber optic connectors and fiber optic flanges (also known as fiber optic adapters) is a crucial link in achieving optical path connection and management in fiber optic communication systems. Fiber optic connectors (such as SC, LC, FC, etc.) are standardized interfaces installed at the ends of optical fibers, used to connect to equipment (such as optical modules, fiber optic transceivers) or other optical fibers. Fiber optic flanges are intermediate transition devices with precise internal alignment structures (such as ceramic sleeves) that accurately align two fiber optic cables with connectors, ensuring low-loss transmission of optical signals. Analogous to the relationship between a plug and socket in an electrical cable, the flange acts as the "socket," and the connector is the "plug," achieving quick connection through a plug-and-play design.

[0003] Traditional FC fiber optic connectors and FC square fiber optic coupling connectors use metal threaded connections. In some humid areas, these metal threaded heads are prone to oxidation and corrosion in humid environments, leading to loose connections or poor contact. Therefore, a fiber optic connector is needed to solve the above problems. Utility Model Content

[0019] 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.

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: an optical fiber connector, including an optical fiber coupling connector 1 and an optical fiber connector 2. An annular plate 101 is fixedly connected to the side end of the optical fiber coupling connector 1. A threaded cylinder 103 is fixedly connected to the side end of the optical fiber coupling connector 1. A connection port 104 is fixedly connected to the side end of the optical fiber coupling connector 1. A knob 201 is fixedly connected to the outer end of the optical fiber connector 2. A connecting cylinder 202 is fixedly connected to the side end of the optical fiber connector 2, threadedly connected to the outer end of the threaded cylinder 103. A plug 204 is fixedly connected to the side end of the optical fiber connector 2, inserted into the connection port 104. A insertion hole 203 is provided on the side end of the optical fiber connector 2. A sealing ring 105 is fixedly connected to the side end of the annular plate 101. A second sealing ring 205 is fixedly connected to the outer end of the connecting cylinder 202. The annular plate 101 is fixedly connected to... There is a side box 102, and the inside of the side box 102 is provided with a limiting component 3 for limiting the fiber optic connector 2. With the setting of the limiting component 3, when the connecting cylinder 202 and the threaded cylinder 103 are fully threadedly connected, the limiting component 3 can limit the connecting cylinder 202. Therefore, even if the fiber optic connector 2 and the fiber optic coupling connector 1 are exposed to a humid environment for a long time, causing the metal thread head to oxidize and corrode, the limiting component 3 can ensure that the connecting cylinder 202 always stays in the original position and there will be no loose connection or poor contact. When the connecting cylinder 202 is fully threadedly connected to the threaded cylinder 103, the sealing ring 105 and the sealing ring 205 are tightly pressed together, so that a sealed space is formed between the connecting cylinder 202 and the threaded cylinder 103, reducing the entry of humid air, thereby avoiding oxidation and corrosion between the threaded cylinder 103 and the connecting cylinder 202.

[0021] As one implementation method in this embodiment, such as Figure 3As shown, the limiting component 3 includes a pull rod 301. A limiting plate 302 is fixedly connected to the side end of the pull rod 301. A connecting rod 303 is fixedly connected to the side end of the limiting plate 302. The connecting rod 303 is inserted into the interior of the side box 102. A circular plate 304 is fixedly connected to the side end of the connecting rod 303. An insert rod 305 is fixedly connected to the side end of the circular plate 304. The insert rod 305 penetrates into the inner wall of the ring plate 101. A spring 306 is sleeved on the outer end of the connecting rod 303. One end of the spring 306... The spring 306 is fixedly connected to the inner wall of the side box 102, and the other end of the spring 306 is fixedly connected to the side end of the circular plate 304. The side end of the plug 305 is round-headed, and the plug hole 203 is adapted to the plug 305. In practice, by aligning the plug 204 of the fiber optic connector 2 with the position of the connection port 104, the fiber optic connector 2 and the connecting cylinder 202 are rotated by rotating the knob 201. At this time, the connecting cylinder 202 is threadedly connected to the outer end of the threaded cylinder 103. When the connecting cylinder 202 rotates... During the process, the side wall gradually contacts the side end of the insertion rod 305. Since the side end of the insertion rod 305 is rounded, it facilitates the movement of the insertion rod 305 when the connecting cylinder 202 rotates to abut against it. At this time, the insertion rod 305 contacts the side wall of the connecting cylinder 202, and the insertion rod 305 drives the circular plate 304 to compress the spring 306 and retract it. When the connecting cylinder 202 and the threaded cylinder 103 are fully threadedly connected, the insertion hole 203 at the side end of the connecting cylinder 202 just rotates to the side end of the insertion rod 305. At this time, the spring 306 pushes against the circular plate 304 to drive the insertion rod 305 to rebound, so that the insertion rod 305 can be inserted into the socket 203 to limit the connection of the connecting tube 202. Therefore, even if the optical fiber connector 2 and the optical fiber coupling connector 1 are exposed to a humid environment for a long time, causing oxidation and corrosion of the metal thread head, the insertion rod 305 can limit the socket 203 and the connecting tube 202 to ensure that the connecting tube 202 always stays in the original position and there will be no loose connection or poor contact.

[0022] Working principle: In use, by aligning the plug 204 of the fiber optic connector 2 with the connection port 104, rotating the knob 201 drives the fiber optic connector 2 and the connecting cylinder 202 to rotate. At this time, the connecting cylinder 202 is threadedly connected to the outer end of the threaded cylinder 103. During the rotation of the connecting cylinder 202, the side wall gradually contacts the side end of the insertion rod 305. Since the side end of the insertion rod 305 is rounded, it is easy to press the insertion rod 305 to move when the connecting cylinder 202 rotates and abuts against the insertion rod 305. At this time, the insertion rod 305 contacts the side wall of the connecting cylinder 202, and the insertion rod 305 drives the circular plate 304 to compress the spring 306. When the connecting cylinder 202 and the threaded cylinder 103 are fully threadedly connected, the insertion hole 203 on the side end of the connecting cylinder 202 just rotates to the side end of the insertion rod 305. At this time, the spring 306 retracts. 06. The circular plate 304 pushes the insertion rod 305 back, allowing the insertion rod 305 to be inserted into the socket 203 to limit the connection of the connecting cylinder 202. Therefore, even if the optical fiber connector 2 and the optical fiber coupling connector 1 are exposed to a humid environment for a long time, causing oxidation and corrosion of the metal thread head, the insertion rod 305 can limit the socket 203 and the connecting cylinder 202, ensuring that the connecting cylinder 202 always remains in its original position and there will be no loose connection or poor contact. When the connecting cylinder 202 is fully threaded with the threaded cylinder 103, the sealing ring 105 and the sealing ring 205 are tightly pressed together, forming a sealed space between the connecting cylinder 202 and the threaded cylinder 103, reducing the entry of humid air, thereby preventing oxidation and corrosion between the threaded cylinder 103 and the connecting cylinder 202.

[0023] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
