Description

Technical Field

[0001] This utility model relates to the field of fiber optic adapter technology, and in particular to a cylindrical fiber optic connector. Background Technology

[0002] In today's rapidly developing communication technology, optical fiber has become the core carrier in the field of information transmission due to its advantages such as high bandwidth, low loss and strong anti-interference ability. As a key component for realizing detachable connection between optical fibers or between optical fibers and equipment, the performance of optical fiber connectors directly affects the stability and transmission efficiency of optical fiber transmission systems.

[0003] The assembly process of some connector components is complex and lacks precise limiting and positioning structures, which can easily lead to component misalignment and coaxiality deviation during assembly. This not only increases the difficulty of the operator's work and reduces assembly efficiency, but may also cause problems such as loose fiber optic cables, signal transmission interruption or attenuation due to unstable component connections and the influence of vibration, external impact, etc. during subsequent use, seriously affecting communication quality. Utility Model Content

[0004] The purpose of this invention is to provide a cylindrical fiber optic connector to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A cylindrical fiber optic connector includes a first cylindrical rod, a second cylindrical rod, a first ring, a connecting rod, and a first sleeve. The first sleeve is fitted onto the left end of the first cylindrical rod. The left end of the first cylindrical rod has a first through-hole. A limiting plate is fixedly installed on the right side of the first cylindrical rod. The second cylindrical rod is fixedly installed on the right side of the limiting plate. An integrally formed second ring is provided in the middle section of the first cylindrical rod. A plurality of axially evenly formed second through-holes are provided on the outer wall of the second ring. A plurality of integrally formed first limiting blocks are provided at the left end of the first ring. The first limiting blocks are located in the second mounting holes. The connecting rod passes through the first mounting holes.

[0006] By adopting the above technical solution, the first sleeve provides protection and positioning for the left end of the first round rod, the first mounting hole provides a stable passage for the connecting rod, and the limiting plate can effectively separate the first round rod and the second round rod to avoid positional interference between them during use; the second mounting hole on the second ring cooperates with the first limiting block of the first ring to accurately limit the relative rotation between the first ring and the first round rod, while ensuring the stability of the connection between the two.

[0007] In a further embodiment, the diameter of the right end of the second round rod is smaller than the diameter of the left end of the second round rod, the diameter of the left end of the limiting plate is larger than the diameter of the right end of the first round rod, and the limiting plate has symmetrical limiting grooves on its upper and lower sides.

[0008] By adopting the above technical solution, the reduced diameter at the right end of the second round rod facilitates its adaptation and insertion with the interface of external equipment, reduces resistance during docking, and improves assembly efficiency. The diameter at the left end of the limiting plate is larger than that at the right end of the first round rod, which can effectively block the right side of the first round rod and prevent excessive displacement of the first round rod during assembly or use. The setting of the limiting groove can provide a snap-fit ​​position for external fasteners or positioning structures, further limiting the positional displacement of the entire connector after installation and enhancing the overall installation stability.

[0009] In a further embodiment, the middle section of the connecting rod is provided with an integrally formed third ring, and the left end of the outer wall of the third ring is provided with an integrally formed fourth ring, and the outer wall of the fourth ring is provided with a third mounting hole that runs through from left to right.

[0010] By adopting the above technical solution, the third ring can fit and limit the inner wall of the first mounting hole, preventing the connecting rod from radially wobbling within the first mounting hole, ensuring the coaxiality of the connecting rod, and providing stable structural support for optical fiber transmission; the fourth ring can axially limit the left end of the connecting rod, preventing the connecting rod from coming out of the left end of the first mounting hole; at the same time, the third mounting hole can serve as an additional positioning or fixing channel, facilitating the insertion of positioning pins or connectors during subsequent assembly, further enhancing the firmness of the connection between the connecting rod and the first ring.

[0011] In a further embodiment, an integrally formed second sleeve is provided at the right end of the first mounting hole of the first round rod, an integrally formed second limiting block is provided at the left end of the second sleeve, the second limiting block is located in the third mounting hole, and an integrally formed fifth ring is provided at the inner left end of the first mounting hole.

[0012] By adopting the above technical solution, the second sleeve can form a wrapping positioning on the right end of the connecting rod, further restricting the radial displacement of the connecting rod and improving the stability of the connecting rod installation; the cooperation between the second limiting block and the third mounting hole can accurately restrict the relative rotation of the connecting rod and the first round rod, avoiding rotational displacement of the connecting rod due to vibration and other factors, and ensuring the stability of the optical fiber connection; the fifth ring can form an axial block on the left end of the connecting rod, and cooperate with the fourth ring to realize bidirectional axial limiting of the connecting rod in the first mounting hole, preventing the connecting rod from axially moving during use.

[0013] In a further embodiment, an integrally formed second sleeve is provided at the right end of the first mounting hole of the first round rod, an integrally formed second limiting block is provided at the left end of the second sleeve, the second limiting block is located in the third mounting hole, and an integrally formed fifth ring is provided at the inner left end of the first mounting hole.

[0014] By adopting the above technical solutions, the fitting of the second sleeve with the right end of the connecting rod can reduce the gap between them, reduce the risk of external dust, moisture and other impurities entering the first mounting hole, and play a certain protective role for the internal optical fiber; the precise fit between the second limiting block and the third mounting hole can not only limit relative rotation, but also enhance the connection strength between the connecting rod and the first round rod through structural interlocking, and improve the impact resistance of the overall structure; the integral molding design of the fifth ring with the inner wall of the first mounting hole can enhance the structural strength of the left end of the first mounting hole, avoid deformation of the mounting hole due to wear after long-term use, and extend the service life of the connector.

[0015] In a further embodiment, the anti-slip strips are evenly distributed along the outer wall of the first sleeve to enhance the friction when the operator holds the first sleeve, facilitating the assembly and disassembly of the sleeve.

[0016] By adopting the above technical solution, the evenly distributed anti-slip strips can effectively increase the contact friction between the operator's hand and the outer wall of the first sleeve. Even when the hands are wet or gloves are worn, the operator can hold the first sleeve stably and avoid slippage during disassembly and assembly. This improves the convenience of disassembly and assembly, reduces the difficulty of operation, reduces damage to components caused by slippage, ensures the integrity of the connector during disassembly and assembly, and improves assembly efficiency.

[0017] In summary, this utility model has the following beneficial effects: 1. The third ring can fit and limit the connection with the inner wall of the first mounting hole, preventing radial wobbling of the connecting rod within the first mounting hole and ensuring the coaxiality of the connecting rod, thus providing stable structural support for optical fiber transmission; the fourth ring can axially limit the left end of the connecting rod, preventing it from coming out of the left end of the first mounting hole; at the same time, the third mounting hole can serve as an additional positioning or fixing channel, facilitating the insertion of positioning pins or connectors during subsequent assembly, further enhancing the firmness of the connection between the connecting rod and the first ring.

[0022] Example 1: like Figures 1-4 As shown, a cylindrical fiber optic connector includes a first cylindrical rod 1, a second cylindrical rod 2, a first ring 3, a connecting rod 4, and a first sleeve 5. The first sleeve 5 is sleeved on the left end of the first cylindrical rod 1. The left end of the first cylindrical rod 1 has a first mounting hole that extends through the left and right sides. A limiting plate 6 is fixedly installed on the right side of the first cylindrical rod 1. The second cylindrical rod 2 is fixedly installed on the right side of the limiting plate 6. The middle section of the first cylindrical rod 1 is provided with an integrally formed second ring 7. The outer wall of the second ring 7 is axially and evenly provided with multiple second mounting holes that extend through the left and right sides. The left end of the first ring 3 is provided with multiple integrally formed first limiting blocks 8, which are located in the second mounting holes. The connecting rod 4 passes through the first mounting holes.

[0023] The diameter of the right end of the second round rod 2 is smaller than the diameter of the left end of the second round rod 2, and the diameter of the left end of the limiting plate 6 is larger than the diameter of the right end of the first round rod 1. Limiting grooves are symmetrically opened on the upper and lower parts of the limiting plate 6.

[0024] The middle section of the connecting rod 4 is provided with an integrally formed third ring 9. The left end of the outer wall of the third ring 9 is provided with an integrally formed fourth ring 10. The outer wall of the fourth ring 10 is provided with a third mounting hole that runs through the left and right sides. The right end of the first mounting hole of the first round rod 1 is provided with an integrally formed second sleeve 11. The left end of the second sleeve 11 is provided with an integrally formed second limiting block 12. The second limiting block 12 is located in the third mounting hole. The left end of the first mounting hole is provided with an integrally formed fifth ring 13.

[0025] An anti-slip strip 14 is provided on the right end of the outer wall of the first sleeve 5, and an clearance hole is provided on the right end of the second round rod 2. An integrally formed limiting ring 15 is provided on the right end of the inner wall of the first sleeve 5. The anti-slip strip 14 is evenly distributed along the outer wall of the first sleeve 5 to enhance the friction when the operator holds the first sleeve 5, and to facilitate the disassembly and assembly of the sleeve.

[0026] Specific implementation process: The first sleeve 5 is inserted into the first round rod 1 from the left end, so that the limiting ring 15 on the inner wall of the first sleeve 5 abuts against the left end of the first round rod 1, completing the initial positioning of the first sleeve 5; then the connecting rod 4 is inserted into the first mounting hole at the left end of the first round rod 1, ensuring that the third ring 9 in the middle section of the connecting rod 4 fits against the inner wall of the first mounting hole, while the second limiting block 12 of the second sleeve 11 at the right end of the first mounting hole is precisely inserted into the third mounting hole of the fourth ring 10 at the left end of the connecting rod 4, and the fifth ring 13 at the left end of the first mounting hole abuts against the outer wall of the connecting rod 4, thereby achieving radial limiting and axial fixing of the connecting rod 4 in the first mounting hole, preventing the connecting rod 4 from shaking or moving. Subsequently, one end of the processed optical fiber is inserted through the clearance hole at the right end of the second round rod 2, passing sequentially through the second sleeve 11 and the inside of the first mounting hole, and finally aligned and fixed with the optical fiber positioning groove at the right end of the connecting rod 4. This ensures that the optical fiber is straight and stable inside the connector, preventing signal transmission from being affected by optical fiber bending. After the optical fiber installation is completed, the first ring 3 is fitted onto the outer wall of the second round rod 2. The internal thread of the inner wall of the first ring 3 is screwed into the external thread of the outer wall of the second round rod 2. During the tightening process, the protrusions on the outer wall of the first ring 3 are used to reduce the effort required until the first limiting block 8 at the left end of the first ring 3 is fully inserted into the second mounting hole of the second ring 7 in the middle section of the first round rod 1. This further enhances the connection stability between the first ring 3 and the first round rod 1. At the same time, the limiting disc 6 on the right side of the first round rod 1 abuts against the elastic washer on the outer wall of the second round rod 2. The elastic washer can buffer the impact of external vibration on the connector and also prevent dust from entering from the gaps. When it is necessary to connect the connector to an external device, hold the anti-slip strip 14 on the outer wall of the first sleeve 5 and use the increased friction of the anti-slip strip 14 to hold it stably. Align the smaller diameter part of the right end of the second round rod 2 with the interface of the external device and insert it. At this time, the limiting groove on the limiting plate 6 can cooperate with the positioning structure of the external device to limit the positional deviation of the connector after docking and ensure accurate docking. After docking, the optical fiber inside the connector transmits signals to the optical fiber of the external device through the connecting rod 4, continuously ensuring the stability of the component position and avoiding the loosening of the optical fiber connection due to vibration or external force, which would affect the transmission effect.
