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 tensile strength structure. Background Technology

[0002] Fiber optic connectors are devices that provide detachable (movable) connections between optical fibers. They precisely align the two end faces of the fibers to maximize the coupling of light energy from the transmitting fiber to the receiving fiber, and to minimize the impact on the system caused by their intervention in the optical link. These are the basic requirements of fiber optic connectors. To a certain extent, fiber optic connectors affect the reliability and performance of optical transmission systems.

[0003] In practical use, connectors and plugs are often subjected to external tension, vibration, or accidental pulling, which can easily cause the plug to loosen or even fall off, affecting the stability of signal transmission. In existing technologies, fiber optic connectors rely solely on the friction of the interface itself or a simple snap-fit ​​structure for fixation, which has limited tensile strength and insufficient reliability under complex working conditions. Therefore, we propose a fiber optic connector with a tensile-resistant structure. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide an optical fiber connector with a tensile structure, so as to solve the problem that in the prior art mentioned in the background, the optical fiber connector relies only on the friction of the interface itself or a simple snap-fit ​​structure for fixation, which has limited tensile strength and insufficient reliability under complex working conditions.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fiber optic connector with a tensile strength structure, comprising a connector body, an interface at one end of the connector body, a plug inserted into the interface, a fixing block fixedly connected to the top and bottom of the interface, a rotating groove at the top of one end of the fixing block, a fixing rod fixedly connected inside the rotating groove, a rotating block rotatably connected inside the rotating groove, a limit groove on the surface of the rotating block, an adjustment structure inside the fixing block, the adjustment structure including an adjustment groove, a threaded rod rotatably connected inside the adjustment groove, a knob fixedly connected to one end of the threaded rod, an adjustment plate rotatably connected to the surface of the threaded rod, a sliding plate slidably connected to the outer side of the threaded rod, two sets of connecting rods symmetrically fixedly connected to the surface of the sliding plate, a spring sleeved on one end of the connecting rod, a limit block fixedly connected to the other end of the connecting rod, a pressure plate rotatably connected to the other end of the connecting rod, and an anti-slip sleeve sleeved on the surface of the pressure plate.

[0006] Preferably, the rotating block is L-shaped, with a circular groove on its short side. The rotating block is rotatably connected to the surface of the fixed rod through the circular groove. The limiting groove is located on the long side of the rotating block. The knob has a square cross-section, and the rotating block is slidably connected to the outside of the knob through the limiting groove.

Detailed Implementation

[0016] 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.

[0017] Please see Figure 1-5 One embodiment provided by this utility model: A fiber optic connector with a tensile strength structure includes a connector body 1. One end of the connector body 1 has an interface 11, and a plug 12 is inserted into the interface 11. A fixing block 13 is fixedly connected to the top and bottom of the interface 11. A rotating groove 14 is formed at the top of one end of the fixing block 13. A fixing rod 15 is fixedly connected inside the rotating groove 14. A rotating block 16 is rotatably connected inside the rotating groove 14. A limit groove 17 is formed on the surface of the rotating block 16. An adjustment structure 2 is provided inside the fixing block 13. The adjustment structure 2 includes an adjustment groove 21. A threaded rod 23 is rotatably connected inside the adjustment groove 21. A knob 22 is fixedly connected to one end of the threaded rod 23. An adjustment plate 24 is rotatably connected to the surface of the threaded rod 23. A sliding plate 25 is slidably connected to the outer side of the threaded rod 23. Two sets of connecting rods 26 are symmetrically fixedly connected to the surface of the sliding plate 25. A spring 27 is sleeved on one end of each connecting rod 26. The other end of the connecting rod 26 is fixedly connected to a limiting block 28, and the other end of the connecting rod 26 is rotatably connected to a pressure plate 29. The surface of the pressure plate 29 is fitted with an anti-slip sleeve 210. A rotating block 16 and an adjustment structure 2 are provided. By rotating the knob 22, the pressure plate 29 can be driven to move towards the plug 12, realizing mechanical clamping, which greatly improves the connection strength and tensile strength between the plug 12 and the connector, effectively preventing loosening or falling off due to external pulling. The rotating block 16 can limit the rotation of the knob 22 to prevent unnecessary rotation and increase the limiting stability of the plug 12. A spring 27 and a pressure plate 29 are provided. Through the spring 27 and the rotatable pressure plate 29, the spring 27 provides uniform clamping force during the clamping process. The pressure plate 29 can fit against the surface of the plug 12. With the rubber anti-slip sleeve 210, the clamping stability and compatibility are further enhanced. The structure is simple and reliable, easy to operate, and suitable for various specifications of optical fibers.

[0018] Furthermore, the rotating block 16 is L-shaped, and a circular groove is provided on the short side of the rotating block 16. The rotating block 16 is rotatably connected to the surface of the fixed rod 15 through the circular groove, so that the rotating block 16 can rotate stably around the fixed rod 15. The limiting groove 17 is provided on the long side of the rotating block 16. The knob 22 has a square cross-section. The rotating block 16 is slidably connected to the outside of the knob 22 through the limiting groove 17. When the rotating block 16 rotates to the outside of the knob 22, it engages with the knob 22 through the limiting groove 17, thereby preventing the knob 22 and the threaded rod 23 from rotating unnecessarily when shaken.

[0019] Furthermore, the surface of the adjusting plate 24 is provided with a threaded groove, and the threaded rod 23 matches the threaded groove. The axial movement of the adjusting plate 24 on the threaded rod 23 is achieved through the threaded engagement. The surface of the adjusting plate 24 is symmetrically provided with two sets of circular grooves. The adjusting plate 24 is slidably connected to the outside of the connecting rod 26 through the circular grooves, ensuring that the adjusting plate 24 remains stable and does not deflect during the movement.

[0020] Furthermore, the surface of the sliding plate 25 is provided with a circular groove three, and the surface of the threaded rod 23 does not contact the inner wall of the circular groove three, so as to avoid interference between the sliding plate 25 and the threaded rod 23. The sliding plate 25 is slidably connected to the outside of the threaded rod 23 through the circular groove three, so that the sliding plate 25 can slide along the axial direction of the threaded rod 23 and provide a stable support foundation for the connecting rod 26.

[0021] Furthermore, the two ends of the spring 27 are fixedly connected to the surface of the sliding plate 25 and the surface of the adjusting plate 24, respectively. The inner side of the spring 27 does not contact the connecting rod 26, so that the spring 27 can apply a uniform thrust when compressed or restored, pushing the adjusting plate 24 to move towards the sliding plate 25, thereby driving the connecting rod 26 and the pressure plate 29 to perform a clamping action.

[0022] Furthermore, the connecting rod 26 is fixedly connected to the limiting block 28 through the inner wall of one end of the adjusting groove 21 to prevent the connecting rod 26 from coming out of the adjusting groove 21. The pressure plate 29 is a rotatable structure on the connecting rod 26, so that the pressure plate 29 can be rotated down to fit against the surface of the plug 12 when in use, and can be rotated and retracted when not in use. The radius of the limiting block 28 is larger than the radius of the connecting rod 26, which plays an axial limiting role. The surface of the pressure plate 29 is provided with rounded corners to facilitate the rotation and adjustment of the pressure plate 29.

[0023] Furthermore, the anti-slip sleeve 210 is made of rubber to increase the friction between the pressure plate 29 and the plug 12, ensuring that it is not easy to slip off after clamping.

[0024] Working principle: In the initial state, the pressure plate 29 is attached to the surface of the fixing block 13 and does not obstruct the interface 11. When it is necessary to lock the plug 12, the plug 12 is inserted into the interface 11, and the knob 22 drives the threaded rod 23 to rotate. Since the adjusting plate 24 cooperates with the threaded rod 23 through the first threaded groove, and the adjusting plate 24 cannot rotate because it slides along the connecting rod 26 through the second circular groove, the rotation of the threaded rod 23 will push the adjusting plate 24 to move, increasing the distance between the adjusting plate 24 and the threaded rod 23. At this time, the spring 27 is no longer in a compressed state and can pull the pressure plate 29 outward. After pulling, the spring 27 is in a compressed state again, rotating the pressure plate 29 around the connecting rod 26. After being released, it is pushed by the action of the spring 27. The adjusting plate 24 moves, pulling the pressure plate 29 through the connecting rod 26, pressing it against the surface of the plug 12. Then, the knob 22 is rotated in the opposite direction to drive the threaded rod 23 to rotate, reducing the distance between the adjusting plate 24 and the threaded rod 23, so that the spring 27 is always in a compressed state. The rubber anti-slip sleeve 210 on its outside increases the friction, thereby firmly pressing the plug 12 into the interface 11 to form a tensile structure. The rotating block 16 is rotated around the fixed rod 15, so that the limiting groove 17 on the rotating block 16 engages with the knob 22, thereby preventing the knob 22 and the threaded rod 23 from rotating unnecessarily when shaken. When it is necessary to disassemble the plug 12, the operation can be reversed. The whole operation process is simple, the clamping force is adjustable, and the structure is stable and reliable.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
