Abstract
Description
Technical Field
[0001] This invention relates to the field of cable connector technology, and in particular to a quick-connect fiber optic cable connector. Background Technology
[0002] As optical fiber communication technology iterates towards higher speed, higher density, and higher reliability, optical fiber cable connectors, as the core interface components for signal transmission, directly determine the operating efficiency and service life of communication systems, especially in industrial vibration environments, outdoor humid and dusty environments, and large-scale equipment deployment scenarios, which place more stringent requirements on the comprehensive performance of connectors.
[0003] Currently, existing fiber optic cable connectors still suffer from numerous technical defects, making it difficult to adapt to the industry's development needs: First, insufficient alignment accuracy. Most traditional connectors use only a single guiding structure, which can easily lead to misalignment or jamming of the plug and socket during insertion and removal, resulting in misalignment between the ferrule and the electrical connection port, causing poor contact, signal attenuation, or equipment damage. This also increases friction loss during insertion and removal, shortens the connector's lifespan, and increases maintenance costs. Second, poor reliability of the locking structure. Traditional connectors often use simple snap-fit or threaded locking methods. Threaded locking is cumbersome and unsuitable for rapid insertion and removal scenarios, while simple snap-fit structures are prone to plug loosening or falling off under conditions such as equipment vibration or external impact, directly causing fiber optic signal interruption and affecting the continuity of the communication system. Third, weak sealing performance. The interface sealing design of existing connectors is often rudimentary, using a single seal or no sealing structure, which cannot effectively prevent external moisture, dust, oil, and other impurities from entering the electrical connection interface. Long-term use can easily cause interface oxidation, corrosion, and short circuits, significantly reducing the safety and durability of the electrical connection and severely limiting the application range of connectors in complex and harsh environments.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
[0027] Reference Figures 1 to 6 As shown, the present invention provides a technical solution: a quick-connect fiber optic cable connector, including a socket 1, a cavity 3 formed on the surface of the socket 1, and a plug 2 provided on one side of the socket 1. A sleeve 8 is fixedly connected to one side of the plug 2. The sleeve 8 is slidably connected to the inner wall of the cavity 3, and an elastic locking block 10 is provided at the upper end of the sleeve 8. One end of the elastic locking block 10 is fixedly connected to one side of the plug 2. A limiting frame 5 is fixedly connected to the top of the socket 1, and a rotating shaft 1 is rotatably connected to the inner wall of the limiting frame 5. 7. A rotating cylinder 16 is sleeved on the surface of the rotating shaft 17. A snap-fit plate 14 is fixedly connected to the upper end of the rotating cylinder 16. Through the sliding connection structure of the socket 1 and the plug 2's insertion cylinder 8 and insertion cavity 3, the mating accuracy of the plug 2 and socket 1 can be ensured, effectively reducing frictional loss during insertion and removal, extending the overall service life of the connector, and reducing equipment maintenance costs. Utilizing the snap-fit cooperation between the elastic locking block 10 and the snap-fit plate 14, and the elastic support of the snap-fit plate 14 by the limiting spring 18, the quick connection between the plug 2 and the socket 1 can be achieved. The quick locking and secure connection effectively prevents the plug 2 from loosening or falling off due to connector vibration or external force during fiber optic cable connection operations, ensuring the stability of fiber optic signal transmission, avoiding signal interruption or transmission errors caused by connection failure, and improving the reliability and continuity of connector use. The interference fit between the sealing ring 13 at the electrical connection port 4 on the inner wall of the socket 3 and the sealing ring groove 20 on the inner wall of the insert 8 effectively blocks external dust, moisture, and other impurities from entering the electrical connection port 4, preventing oxidation, short circuits, and other faults caused by environmental factors, thus improving the safety and durability of fiber optic signal transmission. The sliding fit between the positioning post 11 on one side of the plug 2 and the positioning hole 6 on the side of the socket 1 further enhances the positioning accuracy of the plug 2 and socket 1, ensuring precise electrical connection between the ferrule 12 and the electrical connection port 4, guaranteeing the stability of fiber optic signal transmission, and avoiding signal interference or equipment damage caused by poor contact. Furthermore, the anti-slip texture 19 on the surface of the snap plate 14 facilitates insertion and removal operations, reducing operational difficulty and improving efficiency.
[0028] Reference Figure 2 , Figure 3 and Figure 6 As shown in this embodiment: the surface of the buckle plate 14 is provided with a locking slot 15, which engages with the elastic locking block 10. The upper surface of the buckle plate 14 is provided with anti-slip texture 19, and the lower surface of the buckle plate 14 is fixedly connected to a limit spring 18. The lower end of the limit spring 18 is fixedly connected to the upper surface of the socket 1. The lower end of the insertion cavity 3 is provided with two guide grooves 7, and the lower end of the insertion tube 8 is fixedly connected with two guide strips 9. The guide strips 9 are slidably connected to the inner wall of the guide grooves 7. Through the engagement of the locking slot 15 on the surface of the buckle plate 14 with the elastic locking block 10, and the limit of the lower surface of the buckle plate 14, the buckle plate 14 is effectively secured. The elastic connection between the spring 18 and the upper surface of the socket 1 enables the plug 2 and the socket 1 to lock quickly and securely, effectively preventing the plug 2 from loosening or falling off due to vibration or external force during fiber optic cable connection operations. This ensures the stability of fiber optic signal transmission, avoids signal interruption or transmission errors caused by connection failure, and improves the reliability and continuity of the connector. The sliding connection design between the guide groove 7 at the lower end of the cavity 3 and the guide strip 9 at the lower end of the tube 8 ensures the mating accuracy of the plug 2 and the socket 1, effectively reduces frictional loss during insertion and removal, extends the overall service life of the connector, and reduces equipment maintenance costs.
[0029] Reference Figure 1 , Figure 4 and Figure 5 As shown, specifically, a positioning post 11 is fixed to one side of the plug 2, and a positioning hole 6 is provided on one side of the socket 1. The inner wall of the positioning hole 6 is slidably connected to the surface of the positioning post 11. An electrical connection port 4 is provided in the insertion cavity 3, and a sealing ring 13 is fixedly connected to the surface of the electrical connection port 4. A sealing ring groove 20 is provided on the inner wall of the plug tube 8, and the sealing ring groove 20 is interference-fitted with the sealing ring 13. A plug core 12 is provided on one side of the plug 2, and the plug core 12 is electrically connected to the electrical connection port 4. Through the sliding cooperation between the positioning post 11 on one side of the plug 2 and the positioning hole 6 on one side of the socket 1, the connection between the plug 2 and the socket 1 can be significantly improved. The precision of socket 1 ensures accurate alignment between the ferrule 12 and the electrical connection port 4, preventing poor contact caused by misalignment and guaranteeing the stability of fiber optic signal transmission. The interference fit between the sealing ring 13 at the electrical connection port 4 within the socket 3 and the sealing ring groove 20 on the inner wall of the socket 8 effectively prevents external dust, moisture, and other impurities from entering the electrical connection port 4, avoiding oxidation, short circuits, and other malfunctions caused by environmental factors, thus improving the safety and durability of the electrical connection. Simultaneously, the electrical connection design between the ferrule 12 and the electrical connection port 4 ensures stable current transmission, preventing signal interference or equipment damage caused by poor contact.
[0030] Working principle: First, the positioning pin 11 on one side of the plug 2 and the positioning hole 6 on the side of the socket 1 slide together to achieve precise guidance and positioning of the plug 2 and the socket 1, providing a foundation for subsequent docking operations. Then, the plug 2 is pushed towards the socket 1, causing the plug tube 8 of the plug 2 to slide into the socket cavity 3 of the socket 1. Simultaneously, the guide strip 9 at the lower end of the plug tube 8 slides synchronously with the guide groove 7 at the lower end of the socket 3, ensuring the docking accuracy of the plug 2 and the socket 1 and effectively reducing frictional loss during insertion and removal. After the plug tube 8 is fully inserted into the socket 3, rotating the latch plate 14 causes the locking opening 15 on the surface of the latch plate 14 to engage with the elastic latch 10 at the upper end of the plug tube 8. At the same time, the limiting spring 18 on the lower surface of the latch plate 14 provides elastic support, achieving quick locking and secure engagement of the plug 2 and the socket 1, effectively preventing connector... During fiber optic cable connection operations, the plug 2 may become loose or fall off due to vibration or external force. In the locked state, the sealing ring 13 at the electrical connection port 4 inside the socket 3 forms an interference fit with the sealing ring groove 20 on the inner wall of the plug tube 8, effectively preventing external dust, moisture and other impurities from entering the electrical connection port 4, avoiding malfunctions such as oxidation and short circuits of the electrical connection port 4 caused by environmental factors. At the same time, the core 12 on one side of the plug 2 achieves precise electrical connection with the electrical connection port 4, ensuring the stability of fiber optic signal transmission. When it is necessary to separate the plug 2 from the socket 1, the operator can easily unlock the buckle plate 14 through the anti-slip texture 19 on the surface of the buckle plate 14, so that the lock 15 separates from the elastic block 10, and then the plug 2 can be pulled out of the socket 1. The whole operation process is simple and efficient, and is fully applicable to the industrial production needs of fiber optic cable connection operations.
