Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed in the following specification.
[0024] Embodiment 1
[0025] Please refer to Figures 1-5 , the present invention provides a technical solution: a quick plug connector for a dimming device of an airport navigation lighting system, including an aviation socket 1, one end of the aviation socket 1 is provided with an aviation plug 2, and the surface of the aviation plug 2 is sleeved with a sealing ring 9. The sealing ring 9 is made of fluororubber and has excellent high temperature resistance, corrosion resistance and anti-aging performance, thereby improving the waterproof and dustproof effects of the entire plug connector. One end of the aviation socket 1 is provided with a jack 4, and a pin 3 is fixedly installed on the inner wall of the aviation plug 2. The pin 3 can be made of high-quality copper or copper alloy and has good electrical conductivity and corrosion resistance, thereby ensuring the stability and durability of the electrical connection. A bump 5 is fixedly installed inside the aviation plug 2. The material of the bump 5 can be selected as wear-resistant alloy steel to improve its wear resistance and service life.
[0026] Please refer to Figures 1-5 , the surface of the bump 5 is slidably connected with a protective plate 6. The protective plate 6 is made of high-strength engineering plastic and has excellent impact resistance and corrosion resistance. It can automatically cover the pin 3 when the aviation plug 2 is not inserted, preventing dust and foreign objects from entering, thereby effectively avoiding the occurrence of poor contact. A retaining ring 7 is fixedly installed on the surface of the aviation plug 2. The retaining ring 7 can be made of aluminum alloy or stainless steel and is installed by press-fitting or bolt fixation to ensure that it will not loosen under external force. The surface of the aviation socket 1 is rotatably connected with a threaded cylinder 8. The threaded cylinder 8 meshes with the external thread of the aviation plug 2 and is fixed by the spiral fit of the internal thread and the external thread. The outer surface of the threaded cylinder 8 is provided with anti-slip lines. This design increases the friction force during manual tightening, making the operation more labor-saving.
[0027] Embodiment 2
[0028] Please refer to Figures 3-5 , a stabilizing mechanism is provided inside the aviation plug 2. The stabilizing mechanism includes a cavity 10. A rubber column 15 is fixedly installed on the inner wall of the cavity 10. The rubber column 15 can buffer the stop block 13 to prevent the stop block 13 from being damaged by directly contacting the inner wall of the cavity 10 rigidly. The cavity 10 is opened inside the aviation plug 2. A sliding rod 11 is slidably connected to the inner wall of the cavity 10. The sliding rod 11 can be made of stainless steel or aluminum alloy. These materials have good wear resistance and corrosion resistance to ensure smooth sliding and long service life during the sliding process. A round block 12 is fixedly installed at one end of the sliding rod 11. The round block 12 can be made of wear-resistant rubber or nylon material to ensure sufficient friction when it contacts the suction cup 16, preventing sliding and falling off. The sliding rod 11 is fixedly connected to the protective plate 6, so that when the aviation plug 2 is separated from the aviation socket 1, the protective plate 6 automatically covers the outside of the plug to block foreign objects from entering. A stop block 13 is fixedly installed at the other end of the sliding rod 11. A spring 14 is fixedly installed between the stop block 13 and the inner wall of the cavity 10. The spring 14 is made of high-quality spring steel, with high strength and good anti-fatigue performance, to ensure that it can still maintain a stable elastic force after long-term use. A suction cup 16 is fixedly installed at one end of the aviation socket 1. The suction cup 16 can be made of rubber or silicone material, with good adsorption force and wear resistance, to ensure the preliminary limiting function during the installation process, preventing the aviation socket 1 and the aviation plug 2 from loosening when they are not fully fixed, thereby improving the installation efficiency.
[0029] Working principle: The aviation socket 1 and the aviation plug 2 can be respectively installed on the dimmer circuit. When plugging and unplugging, only need to align the aviation plug 2 and insert it into the aviation socket 1. At this time, the pin 3 is inserted into the jack 4 to connect the dimmer circuit. Then turn the threaded cylinder 8. At this time, the threaded cylinder 8 is tightened on the surface of the aviation plug 2 to firmly fix the aviation socket 1 and the aviation plug 2. At the same time, after the threaded cylinder 8 is tightened, the sealing ring 9 can be pressed. At this time, the sealing ring 9 can improve the sealing performance, thereby improving the waterproof and dustproof performance. And through the arranged protection plate 6, in the default situation, it can block the position outside the aviation plug 2. In this way, when the aviation socket 1 and the aviation plug 2 are in a separated state, it can prevent foreign objects or impurities in the outside world from entering the inside of the aviation plug 2, thus avoiding the occurrence of poor contact. When the aviation plug 2 is inserted into the aviation socket 1, at this time, the aviation socket 1 can squeeze the protection plate 6. At this time, the protection plate 6 slides on the surface of the bump 5, and at this time, the pin 3 is exposed, so as to be normally inserted into the jack 4. By setting the protection plate 6 in the present utility model, when the aviation plug 2 and the aviation socket 1 are separated, it can effectively prevent foreign objects and impurities in the outside world from entering the inside of the plug, reduce the problem of poor contact caused by impurities entering the inside of the plug, improve the reliability, and the protection plate 6 automatically blocks when the plug is not inserted into the socket, and automatically slides to make way when the plug is inserted, and the pin 3 will be exposed. In this way, it can effectively prevent dust from entering. At the same time, because the entry of external impurities is prevented, the faults and wear caused by poor contact can be reduced, thereby prolonging the service life of the plug joint and reducing the maintenance cost. After the aviation socket 1 and the aviation plug 2 are plugged together, due to the elastic force of the spring 14, the spring 14 can drive the block 13 to move. Then the block 13 can drive the sliding rod 11 to move. Then the sliding rod 11 can drive the round block 12 to move. At this time, the round block 12 can be made to extrude the suction cup 16 outwards. At this time, the suction cup 16 can suck the round block 12. In this way, when plugging, the aviation socket 1 and the aviation plug 2 can be initially limited. When turning the threaded cylinder 8, it can prevent the aviation socket 1 and the aviation plug 2 from suddenly loosening, thereby ensuring the installation efficiency. By driving the movement of the block 13, the sliding rod 11 and the round block 12 by the elastic force of the spring 14 in the present utility model, the suction cup 16 sucks the round block 12 to provide the initial limiting function. In this way, when turning the threaded cylinder 8, the adsorption effect of the suction cup 16 provides an additional holding force, making the plug and the socket more stable during the connection process and not easy to loosen, thus making it more convenient to turn the threaded cylinder 8 for fixation.
[0030] The above are only the preferred embodiments of the present utility model, and are not limitations to the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent change equivalent embodiments applied to other fields.
