Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of optical fiber communication connector, especially a kind of optical fiber communication quick connector of anti-bending. BACKGROUND

[0002] Optical fiber connector is the device for detachable (movable) connection between optical fiber and optical fiber, it precisely butts two end faces of optical fiber, so that the light energy output by transmitting optical fiber can be coupled into receiving optical fiber with maximum, and the influence on system due to its intervention in optical link is reduced to minimum, which is the basic requirement of optical fiber connector. To some extent, optical fiber connector affects the reliability and performance of optical transmission system.

[0003] As an important network connection equipment, optical fiber communication quick connector is widely used in data centers, telecommunication networks and various scenarios requiring high-speed data transmission. It connects optical fiber cables together through an efficient and convenient way, ensuring effective signal transmission. However, with the increasing demand for data transmission rate and stability, traditional optical fiber connectors gradually expose some problems in practical application, such as signal loss or interruption caused by optical fiber bending, especially in high-density wiring environment, the management and protection of optical fiber cables become more complex. These problems promote the demand for new optical fiber connector design, aiming to improve the durability and reliability of optical fiber cables.

[0004] In the design of traditional optical fiber communication quick connector, more attention is often paid to the efficiency and convenience of signal transmission, and the physical protection of optical fiber cable itself is insufficient. Optical fiber lines are usually directly exposed or only wrapped by simple shell. In actual use, especially in high-density wiring environment or frequent plugging and unplugging operation, optical fiber lines are easily affected by external pressure, improper bending, etc. If optical fiber line is excessively bent, it may cause internal optical fiber structure to be damaged, causing the twisting or breaking of optical signal transmission path. At the same time, working in inappropriate bending state for a long time will fatigue optical fiber material and reduce its mechanical strength, eventually shorten the service life of optical fiber cable.

[0005] Through retrieval, like existing Chinese patent publication No. CN222125475U discloses a connector for optical fiber communication, which comprises a connector, a cover body is sealingly sleeved on the left side of the connector, a sleeve one is detachably and sealingly connected to the right side of the cover body, and a sleeve two is slidingly and sealingly connected to the right side of the sleeve one. The both ends of the elastic extension assembly are connected with the sleeve one and the sleeve two respectively, and the extension direction of the elastic extension assembly is the same as the sliding direction of the sleeve one.

[0006] The patent documents cited above also have the same problem: insufficient consideration is given to the physical protection of the fiber optic cables themselves. Fiber optic cables are usually directly exposed or only wrapped with a simple outer shell. In actual use, especially in high-density cabling environments or in situations where frequent plugging and unplugging operations are required, fiber optic cables are easily affected by external pressure, improper bending, etc. Utility Model Content

[0007] The purpose of this invention is to provide a bend-resistant quick connector for optical fiber communication to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a bend-resistant fiber optic communication quick connector, comprising a connector assembly, the connector assembly including a connector housing and fiber optic cables and ceramic pins inserted concentrically from both ends of the connector housing, respectively. Two insertion interfaces are symmetrically opened on both sides of the fiber optic cable and on one end of the outer wall of the connector housing. A telescopic support positioning plate is fitted into each insertion interface. A bend-resistant movable support plate is fixed to one end of the two telescopic support positioning plates away from the connector housing. A through hole for the fiber optic cable to pass through is located in the middle of the bend-resistant movable support plate. The bend-resistant movable support plate supports the end of the fiber optic cable away from the connector housing, preventing the extended end of the fiber optic cable from bending. Force-bearing buffer components are symmetrically arranged on the two outer walls of the connector housing, and the two force-bearing buffer components buffer and dampen shock when the connector housing is subjected to downward pressure. Dynamic locking structures for locking and releasing the position of the bend-resistant movable support plate are provided on the other two outer walls of the connector housing.

[0009] In this preferred embodiment, both the anti-bending movable support plate and the connector housing have rectangular end faces, and the two can fit together tightly.

[0010] In a preferred embodiment, the connector housing has two threaded holes symmetrically formed on its two outer walls, each threaded hole communicating with an adjacent insertion interface.

[0011] In this preferred embodiment, the dynamic locking structure includes a locking bolt knob that is threaded into one of the threaded holes on each side.

[0012] In a preferred embodiment, the force-bearing buffer assembly includes two anti-bending U-shaped snap-fit ​​plates symmetrically snapped onto the periphery of the connector housing, a plurality of miniature air buffer springs symmetrically fixed to the outer wall of the opposite side of the two anti-bending U-shaped snap-fit ​​plates, and an anti-bending force-bearing support plate fixed to the other end of the miniature air buffer springs.

[0013] In this preferred embodiment, the anti-bending force support plate is located on the side of the anti-bending U-shaped snap plate away from the connector housing.

[0014] In this preferred embodiment, each of the anti-bending force support plates has countersunk holes at the four corners of the outer wall on the side away from the anti-bending U-shaped snap-fit ​​plate. A positioning pin is inserted into each countersunk hole, and the end of the positioning pin away from the countersunk hole is fixedly connected to the outer wall of the anti-bending U-shaped snap-fit ​​plate.

[0015] In this preferred embodiment, a silicone protective gasket is adhered to the inner wall of each of the anti-bending U-shaped snap-fit ​​plates, and the silicone protective gasket elastically abuts against the outer wall of the connector housing within the anti-bending U-shaped snap-fit ​​plate.

[0016] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0017] This bend-resistant fiber optic communication quick connector features a bend-resistant movable support plate at the end of the fiber optic cable away from the connector housing, with a through hole for the fiber optic cable to pass through. This design provides effective physical support for the fiber optic cable as it extends out of the connector, directly reducing the risk of bending due to external pressure or improper operation. Compared to existing technologies, it improves the durability and lifespan of the fiber optic cable, especially in high-risk operating environments or situations requiring frequent plugging and unplugging, effectively preventing signal transmission interruptions or quality degradation caused by fiber optic cable bending.

[0018] The stress-bearing buffer assembly includes an anti-bending U-shaped snap-fit ​​plate, a miniature air buffer spring, and an anti-bending stress-bearing support plate. These components work together to effectively disperse and absorb energy when subjected to external impact, reducing the impact on the internal optical fiber. Compared with existing technologies, it not only protects the optical fiber from direct physical damage but also reduces signal interference caused by vibration, thereby improving communication quality and reliability.

[0019] The dynamic locking structure can adjust and lock the position of the anti-bending movable support plate according to actual needs. It is very convenient to provide additional support for the fiber optic cable or to restore it to its original state. Compared with the existing technology, it increases the adaptability of the equipment. Users can flexibly adjust the protective measures according to the actual situation, while ensuring sufficient stability to protect the fiber optic cable from external influences in any state.

[0026] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0027] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0028] This embodiment provides, for example Figs. 1 to 3The diagram shows a bend-resistant fiber optic communication quick connector, comprising a connector assembly 1. The connector assembly 1 includes a connector housing 2 and fiber optic cables 3 and ceramic ferrules 4 inserted concentrically from both ends of the connector housing 2. Two insertion interfaces are symmetrically opened on both sides of the fiber optic cables 3, located on one end of the outer wall of the connector housing 2. Each insertion interface is fitted with a telescopic support positioning plate 6. A bend-resistant movable support frame plate 5 is fixed to one end of the two telescopic support positioning plates 6 away from the connector housing 2. The bend-resistant movable support frame plate 5 has a through hole in the middle for the fiber optic cable 3 to pass through. The bend-resistant movable support frame plate 5 supports the end of the fiber optic cable 3 away from the connector housing 2, preventing the extended end of the fiber optic cable 3 from bending. Two force-bearing buffer components 10 are symmetrically arranged on the outer walls of the two symmetrical sides of the connector housing 2. The two force-bearing buffer components 10 buffer and dampen the connector housing 2 when it is subjected to downward pressure, preventing the connector housing 2 from bending. The other two outer walls of the connector housing 2 are provided with dynamic locking structures for locking and releasing the position of the bend-resistant movable support frame plate 5.

[0029] In this embodiment, the end faces of the anti-bending movable support plate 5 and the connector housing 2 are both rectangular, and the two can fit together tightly.

[0030] In this embodiment, two threaded holes 7 are symmetrically opened on the outer walls of both sides of the connector housing 2, and each threaded hole 7 is connected to the adjacent insertion interface.

[0031] In this embodiment, the dynamic locking structure includes a locking bolt knob 8 threadedly connected to one of the threaded holes 7 on each side. When the anti-bending movable support plate 5 drives the telescopic support positioning plate 6 to be pulled out from the insertion interface of the connector housing 2 to support the fiber optic cable 3 against bending, the locking bolt knob 8 is connected to the threaded hole 7 near the end of the anti-bending movable support plate 5. When the anti-bending movable support plate 5 drives the telescopic support positioning plate 6 to retract and no longer support the fiber optic cable 3, the locking bolt knob 8 is connected to the threaded hole 7 away from the end of the anti-bending movable support plate 5.

[0032] In this embodiment, the force-bearing buffer assembly 10 includes two anti-bending U-shaped snap-fit ​​plates 11 symmetrically snapped onto the periphery of the connector housing 2, a plurality of miniature air buffer springs 14 symmetrically fixed to the outer wall of the opposite side of the two anti-bending U-shaped snap-fit ​​plates 11, and an anti-bending force-bearing support plate 9 fixed to the other end of the miniature air buffer springs 14.

[0033] In this embodiment, the anti-bending force support plate 9 is located on the side of the anti-bending U-shaped snap plate 11 away from the connector housing 2. When the anti-bending force support plate 9 is impacted by an external force, the anti-bending force support plate 9 is buffered and shock-absorbing under the action of the miniature air buffer spring 14.

[0034] In this embodiment, each anti-bending force-bearing support plate 9 has countersunk holes 13 at the four corners of its outer wall on the side away from the anti-bending U-shaped snap-fit ​​plate 11. A positioning pin 12 is inserted into each countersunk hole 13, and the end of the positioning pin 12 away from the countersunk hole 13 is fixedly connected to the outer wall of the anti-bending U-shaped snap-fit ​​plate 11. This allows the anti-bending force-bearing support plate 9 to buffer its rise and fall under the longitudinal limitation of the positioning pin 12.

[0035] In this embodiment, a silicone protective gasket 15 is adhered to the inner wall of each anti-bending U-shaped snap plate 11, and the silicone protective gasket 15 elastically abuts against the outer wall of the connector housing 2 in the anti-bending U-shaped snap plate 11.

[0036] Working principle

[0037] The bend-resistant fiber optic communication quick connector inserts the fiber optic cable 3 and ceramic pin 4 from both ends of the connector housing 2 towards the center, ensuring that the fiber optic cable 3 is correctly aligned and passes through the corresponding hole on the connector housing 2. The telescopic support positioning plate 6 is pre-fitted into the insertion interface at the end of the connector housing 2 and is initially fixed by the bend-resistant movable support plate 5.

[0038] When additional anti-bending protection is needed for the fiber optic cable 3, the operator can pull the anti-bending movable support plate 5, causing the telescopic support positioning plate 6 to be pulled out from the insertion interface of the connector housing 2. At this time, the through hole of the anti-bending movable support plate 5 is accurately fitted onto the fiber optic cable 3, providing support for the end of the fiber optic cable 3 away from the connector housing 2, preventing the fiber optic cable 3 from bending at this point. After the anti-bending movable support plate 5 is adjusted into place, the locking bolt knob 8 is used to connect with the threaded hole 7 near one end of the anti-bending movable support plate 5, thereby locking the position of the anti-bending movable support plate 5 and ensuring its stability.

[0039] When the connector is subjected to external downward pressure or impact, the anti-bending force support plate 9 in the force buffer assembly 10 comes into contact with the external force first. Due to the presence of the miniature air buffer spring 14, the anti-bending force support plate 9 can buffer and reduce shock when it is impacted. At the same time, it floats up and down under the longitudinal limiting action of the positioning pin 12 to absorb energy and reduce the impact on the internal components of the connector. The silicone protective pad 15 further enhances the elastic contact between the anti-bending U-shaped snap plate 11 and the connector housing 2, playing a buffering and protective role.

[0040] When additional anti-bending protection is no longer needed, loosen the locking bolt knob 8 and retract the anti-bending movable support plate 5 along with the telescopic support positioning plate 6 back to the initial position. Then, use the locking bolt knob 8 again to lock it back to its original state for easy storage or transportation.

[0041] It should be noted that, in this document, relational terms such as "one" and "two" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
