Description

Technical Field

[0001] This utility model relates to the field of communication accessories technology, specifically to a fiber optic interface locking structure for an optical transceiver module. Background Technology

[0002] In the field of optical communication, optical transceiver modules are key components for transmitting and receiving optical signals, and their performance stability and reliability directly affect the quality of the entire optical communication system. Fiber optic connections, as the bridge between the optical transceiver module and the external optical signal transmission medium, play a crucial role in ensuring efficient and accurate optical signal transmission through their stability, sealing, and ease of operation. With the continuous development of optical communication technology, higher demands are placed on the fiber optic connection technology of optical transceiver modules. How to achieve reliable connection and stable locking of optical fibers under complex environmental conditions has become an urgent problem to be solved in the current optical communication industry.

[0003] Existing fiber optic connection technologies for optical transceivers have several shortcomings. First, the fiber locking force is uneven, making the fiber prone to loosening under external pulling or vibration, thus affecting the transmission quality of the optical signal and even causing signal interruption. Second, the lack of effective anti-slip measures results in low friction between the fiber and the fixed structure, leading to relative slippage during long-term use, reducing optical coupling efficiency and increasing optical signal loss. Third, poor sealing performance allows dust, moisture, and other impurities to easily enter the optical transceiver module, contaminating internal optical components and circuits, causing performance degradation or even damage, and shortening the transceiver module's lifespan. Utility Model Content

[0004] The purpose of this invention is to provide a fiber optic interface locking structure for an optical transceiver module, so as to solve the problem of insufficient locking force of the fiber optic connection in existing transceiver modules mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The optical transceiver module's fiber optic interface locking structure includes an optical transceiver module body and a transmitting fiber optic cable and a receiving fiber optic cable connected to one end of the optical transceiver module body. A fiber optic connector is installed at one end of the optical transceiver module body connected to the fiber optic cable, and a locking mechanism for locking the transmitting fiber optic cable and the receiving fiber optic cable is installed on the fiber optic connector.

[0007] The fiber optic connector is provided with a fiber optic interface for connecting the transmitting fiber optic cable and the receiving fiber optic cable.

[0008] The locking mechanism includes a lower fixed seat and an upper adjustable seat disposed within the fiber optic interface. A pull rod is coaxially connected to the top of the upper adjustable seat. The pull rod passes through the fiber optic connector and extends to the top. A locking return spring is wound around the pull rod and is disposed between the upper adjustable seat and the top of the fiber optic interface.

[0009] Preferably, both the lower fixed seat and the upper adjustable seat have arc-shaped grooves on the side that contacts the optical fiber cable. This allows the optical fiber cable to fit better with the fixing structure, increases the contact area, and makes the force on the optical fiber cable more uniform during fixing, thus improving the stability of the initial fixing. Several sets of uniformly spaced anti-slip protrusions are installed on the inner wall of the arc-shaped groove to increase the friction between the optical fiber cable and the groove, effectively preventing the optical fiber cable from sliding after fixing and ensuring the stability of optical signal transmission.

[0010] Preferably, the anti-slip protrusions are made of silicone rubber, with a height of 3-5mm. Silicone rubber has good flexibility and elasticity, allowing it to fit tightly against the surface of the optical fiber cable without damaging it. The appropriate height provides sufficient friction, enhancing the anti-slip effect and ensuring the optical fiber cable remains stable and fixed in various environments.

[0011] Preferably, the top of the pull rod is provided with a groove, which provides a convenient point of force for the operator to pull the pull rod, making the operation easier and more accurate, facilitating the operation of the locking mechanism, and improving the efficiency of the entire optical fiber connection and locking process.

[0012] Preferably, the ends of the transmitting and receiving optical fiber cables are equipped with connectors that can be plugged into and fixed to the optical transmitting and receiving devices inside the optical transceiver module body. This enables quick and accurate plugging and fixing with the optical transmitting and receiving devices inside the optical transceiver module body, ensuring stable transmission of optical signals between the optical fiber cables and the optical transceiver module and reducing signal loss during transmission.

[0013] Preferably, the transmitting and receiving optical fiber cables are equipped with sealing rings that are compatible with the cross-sectional dimensions of the optical fiber interface. When the optical fiber cables are inserted into the optical fiber interface, the sealing rings can tightly fill the gap between them, thus providing a good sealing effect.

[0014] Preferably, the sealing ring is made of rubber, and the spacing between the lower fixing seat and the optical fiber interface opening is the same as the thickness of the sealing ring, which effectively prevents dust, moisture and other impurities from entering the optical transceiver module, protects the internal components and extends the service life of the optical transceiver module.

[0015] Compared with existing technologies, the advantages of this utility model are as follows: In the optical fiber interface locking structure of this optical transceiver module, the transmission and reception functions of optical signals are realized through the optical transceiver module body and the transmitting and receiving optical fiber cables connected to one end of it; by installing an optical fiber connector at one end of the optical transceiver module body connected to the optical fiber cable, a stable installation foundation is provided for the connection of the optical fiber cable; by opening an optical fiber interface on the optical fiber connector for connecting the transmitting and receiving optical fiber cables, accurate access of the optical fiber cable is ensured; and by installing a locking mechanism on the optical fiber connector... The locking mechanism for the transmitting and receiving fiber optic cables effectively prevents the cables from loosening. The lower fixed seat and upper adjustable seat, located within the fiber optic interface, securely clamp the fiber optic cables. A pull rod coaxially connected to the top of the upper adjustable seat passes through the fiber optic connector and extends to the top, providing a leverage point for operation. A locking and reset spring wound on the pull rod is positioned between the upper adjustable seat and the top of the fiber optic interface. The spring force allows the upper adjustable seat to tightly press the fiber optic cable, achieving reliable locking and ensuring the stability and reliability of the connection between the optical transceiver module and the fiber optic cable.

[0027] The fiber optic interface locking structure of the optical transceiver module, such as Figures 1-3As shown, the system includes an optical transceiver module body 10 and a transmitting optical fiber cable 40 and a receiving optical fiber cable 50 connected to one end of the optical transceiver module body 10. An optical fiber connector 20 is installed at one end of the optical fiber cable connected to the optical transceiver module body 10. A locking mechanism 30 for locking the transmitting optical fiber cable 40 and the receiving optical fiber cable 50 is installed on the optical fiber connector 20. An optical fiber interface 21 for connecting the transmitting optical fiber cable 40 and the receiving optical fiber cable 50 is provided on the optical fiber connector 20. The locking mechanism 30 includes components disposed on the optical fiber connector 40. The fiber optic interface 21 contains a lower fixed seat 31 and an upper adjustable seat 32. A pull rod 33 is coaxially connected to the top of the upper adjustable seat 32. The pull rod 33 passes through the fiber optic connector 20 and extends to the top. A locking and return spring 35 is wound around the pull rod 33. The locking and return spring 35 is located between the upper adjustable seat 32 and the top of the fiber optic interface 21. Through the optical transceiver module body 10 and the transmitting fiber optic cable 40 and receiving fiber optic cable 50 connected to one end of it, the transmission and reception of optical signals are realized. A fiber optic connector 20 is installed at one end of the transmitting module body 10 that connects to the fiber optic cable, providing a stable installation base for the fiber optic cable connection. A fiber optic interface 21 for connecting the transmitting fiber optic cable 40 and the receiving fiber optic cable 50 is provided on the fiber optic connector 20, ensuring accurate connection of the fiber optic cable. A locking mechanism 30 for locking the transmitting fiber optic cable 40 and the receiving fiber optic cable 50 is installed on the fiber optic connector 20, effectively preventing loosening of the fiber optic cable. The lower fixed seat 31 and upper adjustable seat 32, located within the fiber optic interface 21 in the locking mechanism 30, provide a secure clamping grip on the fiber optic cable. A pull rod 33, coaxially connected to the top of the upper adjustable seat 32, passes through the fiber optic connector 20 and extends to the top, providing a point of leverage for operation. A locking and reset spring 35 wound on the pull rod 33 is located between the upper adjustable seat 32 and the top of the fiber optic interface 21. The spring force allows the upper adjustable seat 32 to tightly press the fiber optic cable, achieving reliable locking and ensuring the stability and reliability of the connection between the optical transceiver module and the fiber optic cable.

[0028] Furthermore, both the lower fixed seat 31 and the upper adjustable seat 32 have arc-shaped grooves on the side that contacts the optical fiber cable, allowing the optical fiber cable to better fit the fixing structure, increasing the contact area and improving the stability of the fixation. Several sets of uniformly spaced anti-slip protrusions 36 are installed on the inner wall of the arc-shaped groove. The anti-slip protrusions 36 are made of silicone rubber and have a height of 3-5mm. Silicone rubber has good flexibility and friction. The anti-slip protrusions 36 further increase the friction between the anti-slip protrusions and the optical fiber cable, effectively preventing the optical fiber cable from sliding and ensuring the locking effect.

[0029] The top of the pull rod 33 is provided with a groove 34, which provides a convenient force application point for the operator to pull the pull rod 33, making it easier to operate the locking mechanism 30 and improving the ease of use.

[0030] Specifically, the ends of the transmitting fiber optic cable 40 and the receiving fiber optic cable 50 are equipped with connectors 41 that are plugged into and fixed to the optical transmitting device and optical receiving device inside the optical transceiver module body 10, which realizes the fast and accurate connection between the fiber optic cable and the internal device of the optical transceiver module body 10 and ensures the stability of optical signal transmission.

[0031] In addition, the transmitting fiber optic cable 40 and the receiving fiber optic cable 50 are equipped with sealing rings 42 that are compatible with the cross-sectional dimensions of the fiber optic interface 21. The sealing rings 42 are made of rubber. The spacing between the lower fixing base 31 and the opening of the fiber optic interface 21 is the same as the thickness of the sealing rings 42. When the fiber optic cable is inserted into the fiber optic interface 21, the sealing rings 42 can tightly fill the gap between the fiber optic cable and the fiber optic interface 21, which plays a good sealing role, preventing dust, moisture and other substances from entering the optical transceiver module, protecting the internal components, and improving the reliability and service life of the product.

[0032] The working principle of the fiber optic interface locking structure of this optical transceiver module:

[0033] First, the operator inserts the connectors 41 at the ends of the transmitting fiber optic cable 40 and the receiving fiber optic cable 50 into the corresponding optical transmitting and receiving devices inside the optical transceiver module body 10 to ensure that the optical signal transmission channel is connected normally. Then, the fiber optic cable with the sealing ring 42 is inserted into the fiber optic interface 21 of the fiber optic connector 20. At this time, the sealing ring 42 fits tightly inside the fiber optic interface 21 and plays a sealing role.

[0034] Then, the operator pulls the lever 33 upward through the groove 34 at the top of the lever 33, causing the upper adjustable seat 32 to move upward, and the locking and returning spring 35 is compressed; the optical fiber cable is placed on the lower fixed seat 31, the lever 33 is released, and under the elastic force of the locking and returning spring 35, the upper adjustable seat 32 presses the optical fiber cable downward, and the anti-slip protrusions 36 on the lower fixed seat 31 and the upper adjustable seat 32 increase the friction with the optical fiber cable, thereby achieving the locking and fixing of the optical fiber cable;

[0035] When disassembly is required, pull the pull slot 34 again to separate the upper adjustable seat 32 from the optical fiber cable, and then pull the optical fiber cable out of the optical fiber interface 21 to complete the disassembly operation.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
