Description

Technical Field

[0001] The utility model relates to the technical field of plugs, in particular to an aviation plug. Background Art

[0002] Aviation plugs usually refer to aviation electrical connectors or aviation cable connectors, which are components used for electrical connections of aircraft and related equipment.

[0003] Patent announcement number CN219535016U discloses a quick-to-plug aviation plug, including: a socket unit, which includes a mounting plate, a mounting shell fixedly mounted on the mounting plate, and an aviation socket located in the mounting shell, wherein the mounting shell is fastened with a blocking ring at one end away from the mounting plate, and the blocking ring is provided with multiple groups of evenly distributed embedding ports; a plug unit, which includes multiple groups of aviation plugs matching the aviation socket and installed in the aviation plug, a swivel is rotatably mounted on the back side of the aviation plug, an embedding block matching the embedding port is fixedly mounted on the swivel, and a transmission line is connected to the center of one end of the aviation plug away from the aviation socket, and the transmission line runs through the swivel. Compared with the threaded connection method, the utility model requires less time and greatly improves the docking efficiency of the aviation plug and the aviation socket. Although this type of aviation plug has improved the efficiency of the docking between the plug and the socket, it is lacking in preventing the plug from loosening. Since this type of plug does not have an anti-loosening structure, the plug will fall off due to the staff's accidental touch, thereby causing unnecessary damage. Utility Model Content

[0025] Embodiment 2

[0026] See also Figure 1-4 A fixing hole 14 is provided on the surface of the plug A3, and a cover plate 15 is provided on the surface of the plug B11. The design of the cover plate 15 plays a role in protecting the plug A3 when the socket 1 is not in use. An insertion strip 16 is inserted inside the cover plate 15. The insertion strip 16 is connected to the fixing hole 14 by a thread. The insertion strip 16 and the cover plate 15 are slidably connected. The threaded connection design of the insertion strip 16 and the fixing hole 14 plays a role in fixing the cover plate 15 on the plug A3.

The design of the natural rubber material of the cushion 17 plays a role in increasing the sealing effect of the connection between the cover plate 15 and the plug A3.

[0027] Working principle: When using the aviation plug, you only need to align the plug B11 with the plug A3 through the plug block 10 for insertion. At this time, the sleeve 12 will be sleeved on the plug A3, and the clamping plate 7 will be rotated by the torsion force of the torsion spring 6. The clamping plate 7 will drive the block 8 to be stuck in the slot 13, and the sealing ring 4 will also be stuck in the sleeve 12. At this time, the connection between the plug A3 and the plug B11 is completed. The rotating rod 5, torsion spring 6, clamping plate 7, block 8, sleeve 12, slot 13 and sealing ring 4 enhance the sealing effect of the connection between the plug A3 and the plug B11, thereby improving the socket 1. The cover 15 is waterproof and also prevents the plug A11 from loosening. When the socket 1 is not in use, the cover 15 only needs to be covered on the surface of the plug A3. At this time, the cover 15 will drive the cushion 17 to be stuck in the plug A3, and then the plug 16 is connected to the fixing hole 14 through a thread. After the plug 16 is connected, the installation of the cover 15 can be completed. The cover 15, the plug 16, the fixing hole 14 and the cushion 17 protect the plug A3 when the socket 1 is not in use, thereby preventing dust or water from falling into the plug A3, and also facilitating the disassembly and assembly of the cover 15.
