Description

Technical Field

[0001] This utility model relates to the field of optical fiber connector technology, and in particular to a tensile-resistant optical fiber connector. Background Technology

[0002] With the continuous development of communication technology, optical fiber, as a high-speed, high-bandwidth transmission medium, has been widely used in data centers, metropolitan area networks, long-distance transmission, and access networks. In optical fiber communication systems, fiber optic connectors, as key connecting elements, play a crucial role as bridges and links to ensure reliable connections between optical fibers. Fiber optic connectors not only need to guarantee efficient optical signal transmission but also need to possess good mechanical properties to adapt to installation and usage requirements in different environments. Especially during construction or maintenance, the ease of assembly and tensile strength of fiber optic connectors directly affect the stability and reliability of the overall communication line.

[0003] Existing fiber optic connectors typically consist of components such as a ferrule, a connecting sleeve, and a protective sleeve. The fiber is precisely positioned by the ferrule and then connected to another fiber by the connecting sleeve. To improve connection quality, some fiber optic connectors are equipped with elastic clamping mechanisms or ceramic alignment tubes to reduce insertion loss and improve return loss performance. However, while elastic clamping mechanisms can achieve fiber fixation and alignment to a certain extent, they mainly rely on elastic materials to provide clamping force. Long-term use or frequent disassembly and assembly can lead to material fatigue or decreased elasticity, which in turn affects the fixation effect, resulting in fiber loosening or poor contact. Therefore, a tensile-resistant fiber optic connector is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a tensile-resistant fiber optic connector, which aims to improve the problem that the elastic clamping structure in the prior art suffers from material fatigue or decreased elasticity due to long-term use or frequent disassembly and assembly, thus affecting the fixing effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tensile-resistant fiber optic connector includes an optical fiber and a connector housing. One end of the optical fiber is provided with a connector, and the connector is connected to the connector housing through a tensile-resistant mechanism. A quick-release mechanism is provided on the side wall of the connector housing.

[0007] The tensile mechanism includes splicing rings. The sidewalls of the splicing rings are fixedly connected to the sidewalls of the connector head and the opening of the connector housing. Each sidewall of the splicing ring is fixedly connected with a symmetrical claw and a symmetrical limiting ring. The claws and limiting rings are staggered, and the claws on one side engage with the limiting rings on the other side. The sidewall of the optical fiber is slidably connected inside the connector housing, and the splicing rings are in contact with each other.

[0008] As a further description of the above technical solution:

[0009] The quick-release mechanism includes a locking block and a locking plate. Each connector box has a fixing block fixedly connected inside. The side wall of the locking block is fixedly connected to the side wall of one side of the fixing block, and a fixing frame is fixedly connected inside the other side of the fixing block. One side of the locking plate is rotatably connected to the side wall of the fixing frame.

[0010] As a further description of the above technical solution:

[0011] A spring is provided between the card plate and the adjacent fixing block. One end of the spring is fixedly connected to the side wall of the fixing block, and the other end of the spring is fixedly connected to the side wall of the card plate.

[0012] As a further description of the above technical solution:

[0013] The card plate has a through groove, and the protruding part of the card block is slidably connected to the inside of the groove.

[0014] As a further description of the above technical solution:

[0015] A positioning post is fixedly connected to the side wall of the connector sleeve on one side, and a recessed hole is opened inside the connector sleeve on the other side.

[0016] As a further description of the above technical solution:

[0017] The positioning pin is slidably connected inside the recessed hole, and the connector sleeves fit together.

[0018] As a further description of the above technical solution:

[0019] Both the claw and the sidewall of the limiting ring are provided with abrasive particles to increase the friction between them.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, when connecting the optical fiber cable to the connector cassette, the interlocking action of the splicing ring and the claw ensures a stable connection between the optical fiber cable and the connector cassette, reducing the risk of loosening or falling off. Furthermore, the cooperation between the two enhances the overall fastening force and improves the resistance of the optical fiber cable to external tensile forces during use.

[0022] 2. In this utility model, when connecting the connector sleeve, the positioning pin is slid into the concave hole to achieve initial alignment. When the two are close to each other, the card plate is guided by the protrusion to deflect and stretch the spring. When the groove inside the card plate is aligned with the protrusion of the card plate, the spring returns to its original position and pulls the card plate and the card block to lock together, thus completing the fixation. Through the cooperation between the above structures, the installation efficiency is improved. Attached Figure Description

[0028] 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.

[0029] Reference Figures 1-3 This utility model provides an embodiment of a tensile-resistant fiber optic connector, comprising an optical fiber 1 and a connector housing 3. The optical fiber 1 is an existing SC connector, and a connector 2 is provided at one end of the optical fiber 1. The connector 2 and the connector housing 3 are connected by a tensile-resistant mechanism, which strengthens the connection between the connector 2 and the connector housing 3. A quick-release mechanism is provided on the side wall of the connector housing 3 for quick assembly. The tensile-resistant mechanism includes splicing rings 4, whose side walls are fixedly connected to the side wall of the connector 2 and the opening of the connector housing 3. Multiple splicing rings 4 are provided for connecting the connector 2 and the connector housing 3. Each side wall of the splicing ring 4 is fixedly connected with a symmetrical claw 5 and a symmetrical limiting ring 6. The claws 5 and the limiting rings 6 are staggered, which improves the stability of their interlocking. One side claw 5 and the other side limiting ring 6 are engaged, and there is a distance of movement between the claw 5 and the limiting ring 6 on the same side. During docking, the claws 5 and the limiting rings 6 on both sides of the splicing ring 4 are staggered. The side wall of the fiber optic cable 1 is slidably connected inside the connector sleeve 3. The splicing rings 4 are in contact with each other. The side walls of the claws 5 and the limiting rings 6 are provided with abrasive particles to increase the friction between them and ensure the stability of the splicing.

[0030] Reference Figures 1-3 The quick-release mechanism includes a locking block 10 and a locking plate 12. A fixing block 9 is fixedly connected inside the connector sleeve 3. The side wall of the locking block 10 is fixedly connected to the side wall of one fixing block 9. The side of the locking block 10 closest to the locking plate 12 is protruding. A fixing frame 11 is fixedly connected inside the other fixing block 9. One side of the locking plate 12 is rotatably connected to the side wall of the fixing frame 11. When the locking block 10 and the locking plate 12 approach each other, guided by the protrusion of the locking block 10, the locking plate 12 will deflect on the fixing frame 11. A spring 13 is provided between the locking plate 12 and the adjacent fixing block 9. One end of the spring 13 is fixedly connected to the side wall of the fixing block 9, and the other end of the spring 13... Fixedly connected to the side wall of the card plate 12, when the card plate 12 deflects, it will stretch the spring 13. The spring 13 always provides the force required for the card plate 12 to reset. A groove is opened through the inside of the card plate 12. The protrusion of the card block 10 is slidably connected to the inside of the groove. When the groove inside the card plate 12 moves above the protrusion, the spring 13 will lose pressure and drive the card plate 12 to reset, thereby making the card plate 12 and the card block 10 engage. A positioning post 7 is fixedly connected to the side wall of one connector sleeve 3. A recessed hole 8 is opened inside the other connector sleeve 3. The positioning post 7 is slidably connected to the inside of the recessed hole 8. The connector sleeves 3 are fitted together.

[0031] Working principle: When connecting the fiber optic cable 1 to the connector cassette 3, first insert one end of the fiber optic cable 1 into the connector cassette 3, and align the splicing ring 4 on the connector 2 with the splicing ring 4 inside the connector cassette 3. Then, by twisting the connector 2, the limiting ring 6 on one side gradually slides to the outer wall of the claw 5 on the other side. At the same time, the limiting ring 6 on the other side also gradually slides to the outer wall of the claw 5 on the first side. When both have slid to the middle, the splicing rings 4 on both sides are engaged by the cooperation of the claw 5 and the limiting ring 6, increasing the firmness of the connection between the fiber optic cable 1 and the connector cassette 3. This improves tensile strength. After the workers have connected the two optical fiber cables 1, they can connect the two connector boxes 3, allowing the positioning post 7 to slide into the recessed hole 8 to achieve a preliminary connection. As the connector boxes 3 approach each other, the locking plate 12 will deflect along the protrusion of the locking block 10 on the fixing frame 11, and at the same time stretch the spring 13 to deform it. When the groove inside the locking plate 12 moves above the protrusion, the spring 13 will lose pressure and drive the locking plate 12 to reset, thereby locking the locking plate 12 and the locking block 10, thus completing the locking of the connector box 3.

[0032] 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.
