Abstract
Description
Technical Field
[0001] This invention relates to the field of connector technology, and more specifically, to a navigation light cable connector. Background Technology
[0002] Navigational lighting is a specialized lighting system that provides visual guidance for aircraft takeoff, landing, and taxiing at night or in low visibility conditions. It clearly identifies key information such as runway outlines, approach paths, and taxiway boundaries to the pilot through specific colors, configurations, and light intensities. To ensure the reliable operation of this sophisticated lighting network, dedicated navigational lighting connectors are used to connect the individual lights. These connectors are designed for harsh outdoor environments, possessing excellent waterproof, dustproof, corrosion-resistant, and vibration-resistant properties, and can handle the high current required by the lighting system. Their core function is to achieve a robust and secure electrical and mechanical connection between the lights and the power supply circuit, making them a crucial foundational component for ensuring the stable and uninterrupted operation of the entire navigational lighting system.
[0003] A patent application with publication number CN220086565U discloses an anti-detachment structure and a cable connector for airport ground navigation lights, including a cable connector and a mating cable. By fitting a first anti-detachment ring and a second anti-detachment ring onto the surfaces of the cable connector and the mating cable respectively, the protruding ring at one end of the first anti-detachment ring can be inserted into the groove of the second anti-detachment ring, achieving initial fixation of the cable connector and the mating cable. By installing a fixing block on the surface of the first anti-detachment ring, an adjusting screw can be rotated, causing the adjusting screw to push the moving block to move in the moving groove of the fixing block, thereby adjusting the extension and retraction length of the elastic plate. By installing a mating block on the surface of the second anti-detachment ring, the snap-fit connector at one end of the elastic plate can slide through the snap-fit hole, making the snap-fit connector and the mating block more tightly engaged, making the connection less likely to fall off, ensuring safety in use, and helping to maintain the stable operation of airport navigation lights.
[0004] While the aforementioned device can prevent the connection from falling off during use, the poor environment in which the device is installed, such as exposure to rain and sun, can easily cause the screws to rust and become damaged. This can lead to problems with disassembly and replacement during connector maintenance, reducing the lifespan of the connector and requiring frequent replacement. Summary of the Invention
[0005] This invention provides a navigation light cable connector, which solves the technical problems in related technologies where the connected device is installed in a poor environment, exposed to rain and sun, which easily leads to rust and damage to the screws. This can cause the connector to be unable to be disassembled and replaced during maintenance, resulting in a reduced service life and the need for frequent replacement.
[0006] This invention provides a navigation light cable connector, including a first terminal block with a connecting protrusion fixedly mounted on it. A first interface is fixedly mounted on the side of the connecting protrusion, and a second interface is symmetrically arranged on the side of the first interface. A second terminal block is fixedly mounted on the side of the second interface. A sealing connection device is provided outside the first and second interfaces, allowing the first and second interfaces to connect. The sealing connection device includes a first nut, a connector, an anti-detachment component, a locking component, and a second sealing nut. The first nut is slidably mounted on the second interface, and the connector is provided on the first interface. An anti-detachment component is slidably mounted inside the connector, and a locking component is provided inside the anti-detachment component. The second sealing nut is sleeved on the outside of the locking component. The first nut passes through the second interface and connects to the connector inside the first interface to prevent the connector from detaching from the first interface. The anti-detachment component limits the connector, and the locking component limits the anti-detachment component. When the locking component detaches from the first interface, rotating the second sealing nut facilitates the detachment of the connector from the first nut.
[0007] As a further optimization of the present invention, the connector includes a connecting ring threaded inside the first interface, a second sliding groove symmetrically arranged inside the connecting ring, a third nut slidably installed inside the connecting ring, symmetrically arranged nut protrusions fixedly installed outside the third nut, a connecting block fixedly installed on the side of the nut protrusion, a limit protrusion fixedly installed at the end of the connecting block, a first spring fixedly installed on the side of the third nut, and the end of the first spring is connected to the anti-detachment component.

The first anti-detachment plate has limit notches at both ends for contacting the connecting block. An anti-detachment connecting rod is fixedly mounted on the side of the first anti-detachment plate. A second anti-detachment plate is fixedly mounted on the end of the anti-detachment connecting rod. A second spring is fixedly mounted on the center of the side of the second anti-detachment plate. The end of the second spring is connected to the locking component. Symmetrically arranged rotating columns are fixedly mounted on the side of the second anti-detachment plate.
[0009] As a further optimization of the present invention, the locking member includes locking pins symmetrically arranged and slidably installed inside the second anti-detachment plate. A locking connecting plate is fixedly installed at the end of the locking pin. A locking protrusion is fixedly installed on the locking connecting plate. The locking protrusion is located at the center of the second anti-detachment plate. The second spring is connected to the locking protrusion.
[0010] As a further optimization of the present invention, the second anti-detachment plate is externally threaded with a second sealing nut, and a hexagonal screw is fixedly installed on the side of the second sealing nut, which facilitates the rotation of the second sealing nut.
[0011] As a further optimization of the present invention, a first sliding groove is provided on the side of the first interface near the first nut, and the first sliding groove is threadedly connected to the connecting ring. A limiting groove is provided in a circumferential array on the side of the first interface away from the first nut, and the limiting groove is used to contact the locking post.
[0012] As a further optimization of the present invention, the side of the limiting protrusion is provided with rounded corners, and the farthest distance from the limiting protrusion to the third nut is less than the length of the second groove.
[0013] As a further optimization of the present invention, the minimum distance between the limiting protrusions is less than the length of the first anti-detachment plate.
[0014] As a further optimization of the present invention, the inner wall of the third nut has the same diameter as the outer wall diameter of the thread on the first nut.
[0015] As a further optimization of the present invention, the maximum distance between the third nut and the second anti-detachment plate is less than the width of the first interface.
[0016] The beneficial effects of this invention are as follows: The navigation light cable connector of this invention limits the anti-disengagement component and the connector by using a second sealing nut and locking component inside the sealing connection device, thereby facilitating the installation and disassembly of the connector and preventing the first nut and connector from rusting and becoming unremovable during use. The design of the connector and anti-disengagement component can also lock the connector, preventing the first nut from falling off or stripping during installation, thus improving the installation efficiency and service life of the first and second terminals.

[0019] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.
[0020] like Figures 1 to 3 As shown in the figure, an aid-to-navigation lighting cable connector according to an embodiment of the present invention includes a first terminal 1, a connecting protrusion 14 fixedly installed on the first terminal 1, a first interface 12 fixedly installed on the side of the connecting protrusion 14, a second interface 13 symmetrically arranged on the side of the first interface 12, a second terminal 11 fixedly installed on the side of the second interface 13, and a sealing connection device 2 provided outside the first interface 12 and the second interface 13, the sealing connection device 2 connecting the first interface 12 and the second interface 13; like Figures 4 to 6As shown, the sealing connection device 2 includes a first nut 21, a connector 22, an anti-detachment component 23, a locking component 24, and a second sealing nut 25. The first nut 21 is slidably installed on the second interface 13, and the connector 22 is provided on the first interface 12. The anti-detachment component 23 is slidably installed inside the connector 22, and the locking component 24 is provided inside the anti-detachment component 23. The second sealing nut 25 is sleeved on the outside of the locking component 24. The first nut 21 passes through the second interface 13 and connects to the connector 22 inside the first interface 12 to prevent the connector 22 from coming out of the first interface 12. The anti-detachment component 23 is used to limit the connector 22, and the locking component 24 is used to limit the anti-detachment component 23. When the locking component 24 is detached from the first interface 12, the second sealing nut 25 is rotated to facilitate the detachment of the connector 22 from the first nut 21.
[0021] It should be noted that, due to the influence of the external environment, the first interface 12 and the second interface 13 may rust and loosen when tightened with ordinary bolts. During the next maintenance, water may have entered the first interface 12 and the second interface 13, or the screws may be rusted and unable to be removed. Therefore, a sealing connection device 2 is provided on the first interface 12 and the second interface 13. During installation, the first nut 21 is passed through the second interface 13, and then the hexagonal thread 26 is pressed, so that the second sealing nut 25 and the locking member 24 are connected to the first interface. The first nut 21 is tightened into the connector 22 by contacting the first nut 23, thus achieving a tight fit. The cooperation between the connector 22 and the anti-detachment component 23 prevents detachment. The anti-detachment component 23 and the locking component 24 then contact the side of the first interface 12, achieving a seal and preventing loosening after installation of the first interface 12 and the second interface 13. Simultaneously, the second sealing nut 25 and the hexagonal screw 26 seal the connector 22, preventing further loosening. To address the issue of connector 22 becoming damp and loose due to contact with the external environment, a hexagonal screw 26 is fixedly installed on the side of the second sealing nut 25. When the first nut 21 cannot be removed, the hexagonal screw 26 can be rotated to rotate the second sealing nut 25, allowing it to be removed from the anti-loosening component 23. At this point, the locking component 24 no longer limits the anti-loosening component 23, and the anti-loosening component 23 can be rotated to allow connector 22 to disengage from the first nut 21. This allows the first interface 12 and the second interface 13 to be disassembled, facilitating the removal of the first nut 21. This device limits the anti-detachment component 23 and the connector 22 through the second sealing nut 25 and locking component 24 inside the sealing connection device 2, thereby facilitating the installation and disassembly of the connector 22 and preventing the first nut 21 and the connector 22 from rusting and becoming unremovable during use. The design of the connector 22 and the anti-detachment component 23 can also lock the connector 22, preventing the first nut 21 from falling off or stripping during installation, thus improving the installation efficiency and service life of the first terminal 1 and the second terminal 11.
[0022] like Figures 4 to 5 As shown, the connector 22 includes a connecting ring 221 threaded inside the first interface 12. The connecting ring 221 has a second sliding groove 222 symmetrically arranged inside. A third nut 223 is slidably installed inside the connecting ring 221. Symmetrically arranged nut protrusions 224 are fixedly installed on the outside of the third nut 223. A connecting block 225 is fixedly installed on the side of the nut protrusion 224. A limit protrusion 226 is fixedly installed at the end of the connecting block 225. A first spring 227 is fixedly installed on the side of the third nut 223. The end of the first spring 227 is connected to the anti-detachment component 23.
[0023] It should be noted that the connecting ring 221 is installed on the first interface 12 by a nut, while the third nut 223 and the nut protrusion 224 slide inside the connecting ring 221. Rotating the first nut 21 connects the first nut 21 and the third nut 223, which can drive the connecting block 225 and the limiting protrusion 226 to move closer to the first nut 21. During this process, the anti-detachment component 23 can squeeze the connecting block 225 and the limiting protrusion 226, thereby locking and limiting the third nut 223, preventing the third nut 223 from loosening or stripping during installation.
[0024] like Figures 4 to 6 As shown, the anti-detachment component 23 includes a first anti-detachment plate 231 slidably mounted on the connecting block 225. The first anti-detachment plate 231 has limit notches 234 at both ends, which are used to contact the connecting block 225. An anti-detachment connecting rod 232 is fixedly mounted on the side of the first anti-detachment plate 231. A second anti-detachment plate 233 is fixedly mounted on the end of the anti-detachment connecting rod 232. A second spring 235 is fixedly mounted on the center of the side of the second anti-detachment plate 233. The end of the second spring 235 is connected to the locking component 24. A symmetrically arranged rotating column 236 is fixedly mounted on the side of the second anti-detachment plate 233.
[0025] It should be noted that the first anti-detachment plate 231 and the limiting notch 234 slide on the side of the connecting block 225, which can limit the connecting block 225 and the third nut 223. When the first anti-detachment plate 231 moves away from the third nut 223, it squeezes the limiting protrusion 226, thereby squeezing the limiting protrusion 226 to prevent the third nut 223 from falling off the first nut 21 or even rotating, thus improving the safety and stability of the first interface 12 and the second interface 13 during installation.
[0026] like Figures 5 to 6 As shown, the locking member 24 includes locking pins 243 slidably installed inside the second anti-detachment plate 233. A locking connecting plate 242 is fixedly installed at the end of the locking pin 243. A locking protrusion 241 is fixedly installed on the locking connecting plate 242. The locking protrusion 241 is located at the center of the second anti-detachment plate 233. The second spring 235 is connected to the locking protrusion 241.
[0027] It should be noted that the locking protrusion 241, the locking connecting plate 242, and the locking pin 243 are sequentially fixed together and slide inside the second anti-detachment plate 233. When the side of the second sealing nut 25 is rotated to the same horizontal plane as the side of the second anti-detachment plate 233, the locking pin 243 can be inserted into the first interface 12, thereby limiting the second anti-detachment plate 233. Afterwards, the second sealing nut 25 and the hexagonal screw 26 can be rotated in the opposite direction to remove the second sealing nut 25 from the second anti-detachment plate 233, thereby releasing the limiting effect of the second anti-detachment plate 233.
[0028] like Figures 4 to 5 As shown, the second anti-detachment plate 233 is externally threaded with a second sealing nut 25, and a hexagonal screw 26 is fixedly installed on the side of the second sealing nut 25, which facilitates the rotation of the second sealing nut 25.
[0029] It should be noted that the second anti-detachment plate 233 is externally threaded with a second sealing nut 25. The side of the second sealing nut 25 is fixedly installed with a hexagonal screw 26. The hexagonal screw 26 facilitates the rotation of the second sealing nut 25. The second sealing nut 25 and the hexagonal screw 26 are fixedly installed, and the hexagonal screw 26 can be combined with a wrench to facilitate the disassembly and installation of the second sealing nut 25.
[0030] like Figures 7 to 8 As shown, a first groove 121 is provided on the side of the first interface 12 near the first nut 21. The first groove 121 is threadedly connected to the connecting ring 221. A limiting groove 122 is provided in a circumferential array on the side of the first interface 12 away from the first nut 21. The limiting groove 122 is used to contact the locking post 243.
[0031] It should be noted that the first groove 121 is used for threaded connection with the connecting ring 221, so that the connecting ring 221 can be installed on the first interface 12, and the locking pin 243 can be inserted into the inside of the limiting groove 122, thereby facilitating the purpose of limiting the second anti-detachment plate 233 and the connecting piece 22.
[0032] like Figures 4 to 5 As shown, the side of the limiting protrusion 226 is provided with rounded corners, and the farthest distance from the limiting protrusion 226 to the third nut 223 is less than the length of the second groove 222.
[0033] It should be noted that the side of the limiting protrusion 226 is provided with rounded corners. The farthest distance from the limiting protrusion 226 to the third nut 223 is less than the length of the second slide groove 222, so that the first anti-detachment plate 231 can slide on the side of the connecting block 225. When the third nut 223 moves towards the first nut 21, it can drive the first anti-detachment plate 231 to squeeze the limiting protrusion 226, thereby achieving the effect of rotating and limiting the connecting piece 22.
[0034] like Figures 4 to 5 As shown, the minimum distance between the limiting protrusions 226 is less than the length of the first anti-detachment plate 231.
[0035] It should be noted that the minimum distance between the limiting protrusions 226 is less than the length of the first anti-detachment plate 231. When the first anti-detachment plate 231 moves, it can lock and limit the third nut 223.
[0036] like Figures 4 to 5 As shown, the inner wall of the third nut 223 has the same diameter as the outer wall of the thread on the first nut 21.
[0037] It should be noted that the inner wall of the third nut 223 has the same diameter as the outer wall of the thread on the first nut 21, so that the first nut 21 can be installed on the third nut 223.
[0038] like Figures 4 to 6 As shown, the maximum distance between the third nut 223 and the second anti-detachment plate 233 is less than the width of the first interface 12.
[0039] It should be noted that the maximum distance between the third nut 223 and the second anti-detachment plate 233 is less than the width of the first interface 12. When the first nut 21 rotates, the third nut 223 can move closer to the first nut 21, and the second anti-detachment plate 233 can seal the side of the first interface 12.
[0040] The embodiments of the present invention have been described above, but the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of the embodiments described above, all of which are within the protection scope of the present invention.
