Abstract
Description
Technical Field
[0001] This utility model relates to the field of aviation plug technology, specifically a stable rectangular aviation plug mechanism. Background Technology
[0002] Aviation connectors, also known as aviation plugs, are specialized electrical connectors originating in the military industry and now widely used in various scenarios requiring reliable connections. Aviation connectors achieve circuit interconnection through the elastic contact between the elastic contacts of the female connector and the rigid contacts of the male connector. When the plug and socket are correctly connected, a stable electrical connection is formed between the contacts, ensuring stable signal and power transmission. Aviation connectors are widely used in various scenarios requiring reliable connections, such as: Military: Widely used between electronic devices in military equipment such as tanks, warships, and aircraft to ensure reliable information transmission and equipment effectiveness. Industrial: Used in factory automation equipment to connect sensors and control systems to ensure accurate data transmission. Transportation: Used to connect various electronic devices and control systems to ensure the safe operation of vehicles. Rectangular aviation connectors are used to connect power, signal, and data transmission between different devices or systems.
[0003] Traditional stable rectangular aviation connector mechanisms connect the rectangular aviation connectors via a plug-in method. However, over prolonged use, this not only leads to insufficient stability and a tendency for the connector to detach, but also increases the risk of damage. To address these issues, some stable rectangular aviation connector mechanisms use a threaded connection for the connector, thereby improving stability, preventing detachment, and reducing the risk of damage. However, this threaded connection method not only results in longer connection times but also increases maintenance difficulty. Therefore, a stable rectangular aviation connector mechanism is proposed. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this invention provides a stable rectangular aviation plug mechanism to solve the aforementioned technical problems that not only result in longer connection times but also increase maintenance difficulty.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a stable rectangular aviation plug mechanism, comprising:
[0008] A mounting base and a socket located on the front of the mounting base, wherein a convex ring plate is added to the front of the socket, and a rectangular plug is inserted into the front of the socket, wherein the surface of the rectangular plug is respectively provided with a concave ring groove and a cable is installed thereon.
[0009] A fixing plate is set on the front of the fixing base, and a cylindrical rod is inserted into the upper surface of the fixing plate. A limit hole is opened on the top of the fixing plate, and limit edges are installed on both sides of the cylindrical rod. A compression spring is sleeved on the surface of the cylindrical rod, and the two ends of the compression spring are respectively attached to the fixing plate and the cylindrical rod.
[0010] A fixed inclined post is located at the bottom end of a cylindrical rod and is rotatably connected to the cylindrical rod. The bottom end of the fixed inclined post is in contact with the surface of the rectangular plug. After the rectangular plug is inserted into the socket, the convex ring plate enters the interior of the concave ring groove. The compression spring drives the cylindrical rod to descend on the fixed plate, while the limiting edge moves in the same direction as the cylindrical rod along the limiting hole. The cylindrical rod drives the fixed inclined post to fit tightly against the surface of the rectangular plug. The cylindrical rod rotates on the fixed plate, causing the limiting edge below the fixed plate to misalign with the limiting hole. When separating the rectangular plug from the socket, the cylindrical rod is first rotated on the fixed plate to align the limiting edge below the fixed plate with the limiting hole, and then the rectangular plug is pulled out. Since the surface of the rectangular plug and the bottom end of the fixed inclined post are both inclined, the rectangular plug can drive the fixed inclined post to move upward along the bottom end of the fixed inclined post, and the cylindrical rod compresses the compression spring. On the one hand, this not only reduces connection time but also reduces maintenance difficulty; on the other hand, it not only ensures the stability of the connection between the socket and the rectangular plug but also facilitates disassembly and assembly operations.
[0011] Preferably, the fixing base has positioning side grooves on both sides, and positioning side blocks are installed on both sides of the rectangular plug. After the rectangular plug is inserted into the socket, the positioning side blocks are inserted into the positioning side grooves.
[0012] Preferably, the positioning side groove corresponds to the shape and position of the positioning side block, and the surface of the positioning side block is provided with a fixing hole. After the positioning side block is inserted into the positioning side groove, the positioning side block is connected to the corresponding structure through the fixing hole.
[0013] Preferably, the fixing base has connecting handles rotatably connected to both sides, and connecting holes are provided around the front perimeter of the fixing base. The fixing base can be installed in a suitable location through the connecting holes, and the connecting handles can be rotated on the fixing base.
[0014] Preferably, an outer beveled rod is installed on the inner side of the connecting handle, and the outer beveled rod is rotatably connected to the inner cavity of the fixed base. An inner beveled rod is added to the inner end of the outer beveled rod. When the connecting handle drives the outer beveled rod to rotate on the fixed base, the inner beveled rod will not rotate with the outer beveled rod because of its square design. When the beveled end of the outer beveled rod rotates to a certain angle, it can drive the inner beveled rod to move inward along the inner wall of the fixed base.
[0015] Preferably, a return spring is sleeved on the surface of the inner inclined rod, and a fixing rod is installed at the end of the inner inclined rod, with the position and shape of the fixing rod corresponding to the fixing hole. When the inner inclined rod moves inward along the inner wall of the fixing seat, it compresses the return spring, while the fixing rod moves in the same direction as the inner inclined rod and enters the positioning side groove to be inserted into the fixing hole on the positioning side block for connection. When the connecting handle drives the outer inclined rod to reset on the fixing seat, the inner inclined rod resets under the action of the return spring, and the inclined ends of the outer and inner inclined rods fit tightly together. The fixing rod moves with the inner inclined rod to the inner cavity of the fixing seat to separate from the fixing hole, thereby further ensuring the connection stability of the socket and the rectangular plug, and also facilitating disassembly and assembly operations.
[0016] (III) Beneficial Effects
[0017] Compared with the prior art, this utility model provides a stable rectangular aviation plug mechanism, which has the following advantages:
[0018] This stable rectangular aviation plug mechanism works by inserting the rectangular plug into the socket, causing the convex ring plate to enter the concave ring groove. The compression spring drives the cylindrical rod to descend on the fixed plate, while the limiting edge moves in the same direction as the cylindrical rod along the limiting hole. The cylindrical rod drives the fixed inclined post to fit tightly against the surface of the rectangular plug. The cylindrical rod rotates on the fixed plate, causing the limiting edge below the fixed plate to misalign with the limiting hole. When separating the rectangular plug from the socket, the cylindrical rod is first rotated on the fixed plate to align the limiting edge below the fixed plate with the limiting hole, and then the rectangular plug is pulled out. Because the surface of the rectangular plug and the bottom of the fixed inclined post are both designed to be inclined, the rectangular plug can drive the fixed inclined post to move upward along the bottom of the fixed inclined post, and the cylindrical rod compresses the compression spring. This not only reduces connection time and maintenance difficulty, but also ensures the stability of the connection between the socket and the rectangular plug, and facilitates disassembly and assembly operations.

[0024] 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.
[0025] This utility model provides a technical solution: a stable rectangular aviation plug mechanism, including: (See details) Figure 1 , Figure 2 The fixed base 1 and the socket 2 provided on the front of the fixed base 1, and the front of the socket 2 is provided with a protruding ring plate 4, and a rectangular plug 5 is inserted into the front of the socket 2, and the surface of the rectangular plug 5 is respectively provided with a concave ring groove 7 and a cable 8 is installed.
[0026] Please see Figure 3 A fixing plate 10 is disposed on the front of the fixing base 1, and a cylindrical rod 11 is inserted into the upper surface of the fixing plate 10. A limiting hole 12 is opened on the top of the fixing plate 10, and limiting edges 13 are installed on both sides of the cylindrical rod 11. A compression spring 14 is sleeved on the surface of the cylindrical rod 11, and the two ends of the compression spring 14 are respectively attached to the fixing plate 10 and the cylindrical rod 11.
[0027] A fixed inclined post 15 is located at the bottom end of the cylindrical rod 11 and is rotatably connected to the cylindrical rod 11. The bottom end of the fixed inclined post 15 is in contact with the surface of the rectangular plug 5. After the rectangular plug 5 is inserted into the socket 2, the convex ring plate 4 enters the interior of the concave ring groove 7. The compression spring 14 drives the cylindrical rod 11 to descend on the fixed plate 10, while the limiting edge 13 moves in the same direction as the cylindrical rod 11 along the limiting hole 12. The cylindrical rod 11 drives the fixed inclined post 15 to fit tightly against the surface of the rectangular plug 5, and rotates the cylindrical rod 11 on the fixed plate 10, causing the limiting edge 13 below the fixed plate 10 to be misaligned with the limiting hole 12. When the rectangular plug 5 is separated from the socket 2, it first rotates on the fixed plate 10. The cylindrical rod 11 aligns the limiting edge 13 below the fixing plate 10 with the limiting hole 12, and pulls out the rectangular plug 5. Since the surface of the rectangular plug 5 and the bottom of the fixing inclined post 15 are both inclined, the rectangular plug 5 can drive the fixing inclined post 15 to move upward along the bottom of the fixing inclined post 15, and the cylindrical rod 11 will press the compression spring 14. On the one hand, this not only reduces the connection time but also reduces the maintenance difficulty; on the other hand, it not only ensures the connection stability between the socket 2 and the rectangular plug 5 but also facilitates disassembly and assembly operations.
[0028] Please see Figure 4The fixed base 1 has positioning grooves 3 on both sides, and positioning blocks 6 are installed on both sides of the rectangular plug 5. After the rectangular plug 5 is inserted into the socket 2, the positioning blocks 6 are inserted into the positioning grooves 3. The positioning grooves 3 and the positioning blocks 6 correspond in shape and position, and the surface of the positioning blocks 6 has fixing holes 9. After the positioning blocks 6 are inserted into the positioning grooves 3, they are connected to the corresponding structure through the fixing holes 9. The fixed base 1 has connecting handles 20 rotatably connected to both sides, and the front of the fixed base 1 has connecting holes around its perimeter. The fixed base 1 can be installed in a suitable location through the connecting holes, and the connecting handles 20 can be rotated on the fixed base 1. The inner surface of the connecting handles 20 is equipped with an outer bevel rod 16, and the outer bevel rod 16 is rotatably connected to the inner cavity of the fixed base 1, with an inner bevel rod 17 added to the inner end of the outer bevel rod 16. When the connecting handle 20 drives the outer inclined rod 16 to rotate on the fixed base 1, the inner inclined rod 17, being square in design, will not rotate with the outer inclined rod 16. When the inclined end of the outer inclined rod 16 rotates to a certain angle, it can drive the inner inclined rod 17 to move inward along the inner wall of the fixed base 1. A return spring 18 is sleeved on the surface of the inner inclined rod 17, and a fixing rod 19 is installed at the end of the inner inclined rod 17. The position and shape of the fixing rod 19 correspond to those of the fixing hole 9. When the inner inclined rod 17 moves inward along the inner wall of the fixed base 1, it presses the return spring 18. The fixed rod 19 moves in the same direction as the inner inclined rod 17 and enters the positioning side groove 3 to be inserted into the fixing hole 9 on the positioning side block 6 for connection. When the connecting handle 20 drives the outer inclined rod 16 to reset on the fixed base 1, the inner inclined rod 17 is reset under the action of the return spring 18. The inclined ends of the outer inclined rod 16 and the inner inclined rod 17 are tightly fitted. The fixed rod 19 moves with the inner inclined rod 17 to the inner cavity of the fixed base 1 and separates from the fixing hole 9. This further ensures the connection stability between the socket 2 and the rectangular plug 5 and facilitates disassembly and assembly.
[0029] This solution: After the rectangular plug 5 is inserted into the socket 2, the convex ring plate 4 enters the concave ring groove 7, and the positioning side block 6 is inserted into the positioning side groove 3. The compression spring 14 drives the cylindrical rod 11 to descend on the fixed plate 10, while the limiting edge 13 moves in the same direction as the cylindrical rod 11 along the limiting hole 12. The cylindrical rod 11 drives the fixed inclined post 15 to fit tightly against the surface of the rectangular plug 5, and rotates the cylindrical rod 11 on the fixed plate 10, so that the limiting edge 13 below the fixed plate 10 is misaligned with the limiting hole 12. When the rectangular plug 5 is separated from the socket 2, first rotate the cylindrical rod 11 on the fixed plate 10 so that the limiting edge 13 below the fixed plate 10 corresponds to the position of the limiting hole 12, and then pull out the rectangular plug 5. Since the surface of the rectangular plug 5 and the bottom end of the fixed inclined post 15 are both designed to be inclined, the rectangular plug 5 can drive the fixed inclined post 15 to move upward along the bottom end of the fixed inclined post 15. The cylindrical rod 11 presses the compression spring 14. When the connecting handle 20 drives the outer inclined rod 16 to rotate on the fixed seat 1, the inner inclined rod 17 is square in design, so it does not rotate with the outer inclined rod 16. When the inclined end of the outer inclined rod 16 rotates to a certain angle, it can drive the inner inclined rod 17 to move inward along the inner wall of the fixed seat 1 and press the return spring 18. The fixed rod 19 moves in the same direction as the inner inclined rod 17 and enters the positioning side groove 3 and is inserted into the fixing hole 9 on the positioning side block 6 for connection. When the connecting handle 20 drives the outer inclined rod 16 to reset on the fixed seat 1, the inner inclined rod 17 is reset under the action of the return spring 18. The inclined ends of the outer inclined rod 16 and the inner inclined rod 17 are tightly fitted. The fixed rod 19 moves with the inner inclined rod 17 to the inner cavity of the fixed seat 1 and separates from the fixing hole 9.
