Description

Technical Field

[0001] This utility model relates to the field of aviation plug technology, specifically to an aviation plug designed to prevent incorrect insertion. Background Technology

[0002] An aviation connector is an electromechanical component used to connect electrical circuits. It is named after its initial widespread use in the aerospace field. It connects and disconnects circuits or transmits signals by plugging in male and female connectors. It features high reliability, environmental resistance, and convenience.

[0003] Existing aviation connectors typically have anti-misinsertion structures to prevent male and female connectors from being inserted incorrectly. However, the effectiveness of these structures is limited. When the male and female connectors are inserted incorrectly, the female connector can still contact the male connector's pins. If external force is applied to force them in, the pins may bend or even break, rendering the aviation connector unusable. Utility Model Content

[0004] The purpose of this invention is to provide an aviation plug that prevents incorrect insertion, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-misinsertion aviation plug, comprising a male and a female connector. The female connector has a groove on its outer side, and the male connector has a protrusion on its inner side that mates with the groove. Multiple pins are installed inside the male connector. A positioning sleeve is slidably installed on the outer side of the male connector. A through hole for the female connector to pass through is opened on one side of the positioning sleeve. A positioning block corresponding to the groove is provided on the inner wall of the through hole. A second sliding groove is symmetrically opened on the inner side of the positioning sleeve. A plug rod is fixedly connected inside the second sliding groove. A first sliding groove is symmetrically opened on the male connector. A stop frame is slidably installed inside the first sliding groove. The bottom of the stop frame has a hemispherical portion. A second through hole is opened through the middle of the stop frame. A fixing post is provided at the bottom of the inner wall of the second through hole. A spring is sleeved on the outer side of the fixing post. A horizontal plate is provided inside the first sliding groove. The stop frame is slidably installed on the outer side of the horizontal plate. Stop blocks are provided on both sides of the stop frame.

[0006] As a preferred embodiment of this utility model, the outer side of the male head is integrally formed with a limiting block, and the limiting block is provided with a first through hole for the insertion rod to pass through.

[0007] In a preferred embodiment of this utility model, the bottom of the spring abuts against the hemispherical portion, and the top of the spring abuts against the horizontal plate.

[0008] In a preferred embodiment of this utility model, the widths of the first through hole, the second through hole, and the insertion rod are all equal.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: Through the synergistic effect of the positioning sleeve, positioning block, insertion rod, spring, fixing post, hemispherical part and stop frame, this utility model ensures that when the female and male connectors are inserted incorrectly, the female connector cannot contact the pin at all. Compared with the traditional anti-misinsertion structure, it fundamentally eliminates the hidden danger of the pin bending due to forced insertion by misoperation, and effectively improves the safety and reliability of aviation plug connection.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 11 This utility model provides a technical solution: an aviation connector to prevent mis-insertion, including a male connector 1 and a female connector 2. The female connector 2 is inserted into the right end of the male connector 1. The outer side of the female connector 2 has a groove 3, and the inner side of the male connector 1 has a protrusion 4 that mates with the groove 3. The groove 3 and the protrusion 4 provide positioning for the male connector 1 and the female connector 2, preventing mis-insertion. The male connector 1 has multiple pins 5 installed inside, and a positioning sleeve 6 is slidably installed on the outer side of the male connector 1. When the female connector 2 and the male connector 1 are mis-inserted, that is, when the groove 3 is not aligned with the positioning sleeve 6, the mis-insertion occurs. At this time, the female head 2 cannot pass through the through hole 8, and the insertion rod 17 is not aligned with the second through hole 11. Therefore, the insertion rod 17 is blocked by the stop frame 19, causing the positioning sleeve 6 to be unable to move. Due to the obstruction of the positioning sleeve 6, the female head 2 cannot contact the insertion pin 5, thus preventing the insertion pin 5 from bending. A through hole 8 is provided on one side of the positioning sleeve 6 for the female head 2 to pass through. The inner wall of the through hole 8 is provided with a positioning block 7 corresponding to the groove 3. The positioning block 7 is aligned with the protrusion 4. Only when the groove 3 on the female head 2 is aligned with the positioning block 7 can the female head 2 pass through the through hole 8. The inner side of the positioning sleeve 6 is symmetrically provided with a second sliding groove 18. A plug rod 17 is fixedly connected inside the second sliding groove 18. The male head 1 is symmetrically provided with a first sliding groove 16. A stop frame 19 is slidably installed inside the first sliding groove 16. The bottom of the stop frame 19 is provided with a hemispherical part 14. When the female head 2 contacts the hemispherical part 14, it will squeeze and make it move. The hemispherical part 14 drives the stop frame 19 to move. A second through hole 11 is provided through the middle of the stop frame 19. The bottom of the inner wall of the second through hole 11 is provided with a fixing post 13. The outer side of the fixing post 13 is... A spring 12 is provided on the side sleeve. The spring 12 is used to apply a pushing force to the hemispherical part 14 so that when the female head 2 is not inserted into the male head 1, the second through hole 11 is always in a position that is not aligned with the insertion rod 17. A horizontal plate 15 is provided on the inner side of the first sliding groove 16. The stop frame 19 is slidably installed on the outer side of the horizontal plate 15. Both sides of the stop frame 19 are provided with a stop block 20. The stop block 20 is used to block the stop frame 19 and prevent the stop frame 19 from moving too much into the male head 1 under the action of the spring 12, which would prevent the stop frame 19 from blocking the female head 2 from being inserted into the male head 1.

[0024] Among them, the outer side of the male head 1 is symmetrically integrally formed with a limiting block 9. The limiting block 9 is used to limit the positioning sleeve 6, making the positioning sleeve 6 more stable when sliding and preventing it from rotating with the male head 1. The limiting block 9 is provided with a first through hole 10 for the insertion rod 17 to pass through. The first through hole 10 is aligned with the insertion rod 17, so that the insertion rod 17 can pass through the first through hole 10, avoiding the insertion rod 17 being blocked by the limiting block 9, which would prevent the positioning sleeve 6 from moving.

[0025] The bottom of the spring 12 abuts against the hemispherical part 14, and the top of the spring 12 abuts against the horizontal plate 15. When the stop frame 19 moves to the outside of the male head 1, the stop frame 19 drives the hemispherical part 14 to move, and the hemispherical part 14 and the horizontal plate 15 cooperate to squeeze the spring 12.

[0026] The widths of the first through hole 10, the second through hole 11, and the insertion rod 17 are all equal, ensuring that the insertion rod 17 can pass smoothly through after being aligned with the first through hole 10 and the second through hole 11.

[0027] Specifically, when the female head 2 and the male head 1 are inserted, there are two situations. If the insertion is incorrect, that is, the groove 3 is not aligned with the positioning block 7, the female head 2 will not be able to pass through the through hole 8. At the same time, the insertion rod 17 is misaligned with the second through hole 11 on the stop frame 19, causing the insertion rod 17 to be blocked by the stop frame 19, making the positioning sleeve 6 unable to slide. Due to the obstruction of the positioning sleeve 6, the female head 2 cannot contact the insertion pin 5, thus effectively preventing the insertion pin 5 from bending due to forced insertion. If the alignment is normal, that is, the groove 3 is aligned with the positioning block 7, one end of the female head 2 passes through the through hole 8 and is partially inserted into the male head 1. During the insertion process, the female head 2 squeezes the hemispherical part 14, causing it to move outward, thereby driving the stop frame 19 to move outward synchronously, causing the second through hole 11 to align with the insertion rod 17, so that the positioning sleeve 6 can slide. At this time, the main body of the female head 2 has not yet contacted the positioning sleeve 6. As the female head 2 is further inserted, the main body of the female head 2 will contact and push the positioning sleeve 6 to move until the female head 2 and the male head 1 are completely inserted.
