Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and in particular to a quick-maintenance aviation plug assembly for an aircraft simulator. Background Technology

[0002] As a key component for ensuring reliable transmission of electrical signals and energy, aviation connectors are widely used in aerospace, precision instruments, and aircraft simulators, where connection reliability is extremely important. In these applications, aviation connectors not only need to have excellent vibration resistance, environmental corrosion resistance, and electromagnetic shielding performance to ensure stable operation of equipment under complex working conditions, but the ease of maintenance of their structure is also equally important.

[0003] As a high-value training device, the aircraft simulator places high demands on the maintainability of all components in order to ensure its high uptime and training efficiency. When the circuit system in the simulator malfunctions or needs to be upgraded, maintenance personnel often need to inspect, repair or replace the internal wiring of the aviation connector.

[0004] In existing technologies, the plug body of an aviation connector is typically fastened to the tail sleeve used to secure the cable using multiple threaded fasteners. When maintenance is required, maintenance personnel must use tools such as screwdrivers to unscrew these tiny screws one by one in order to separate the tail sleeve from the plug body and expose the internal pin terminals. This process is not only cumbersome and time-consuming, but also prone to falling or being lost in the confined or poorly lit workspace of a simulator. This undoubtedly increases the difficulty and time cost of maintenance and reduces the overall operational efficiency of the equipment. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a quick-maintenance aviation plug assembly for an aircraft simulator, aiming to improve the problems of complex disassembly and assembly processes and long time consumption during the maintenance of existing aviation plug assemblies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A quick-maintenance aviation plug assembly for an aircraft simulator includes: a plug body, a tail sleeve, and a locking sleeve; and a disassembly and assembly assembly disposed between the plug body and the tail sleeve.

[0008] The plug body is coaxially positioned at the front of the tail sleeve, and the locking sleeve is rotatably fitted onto the outside of the plug body. The disassembly and assembly assembly is used to enable quick disassembly and assembly between the plug body and the tail sleeve.

[0009] The assembly includes a first connecting block fixedly connected to the plug body and a second connecting block fixedly connected to the tail sleeve. The first connecting block has a plug rod that can be inserted into the second connecting block. The end of the plug rod has an anti-disengagement block, and the plug rod is also connected to the handle. The second connecting block has an elastic locking plate inside. The outer circumference of the plug rod has a bevel that cooperates with the elastic locking plate. When the plug rod is inserted into the second connecting block, the anti-disengagement block opens the elastic locking plate and rebounds after passing the elastic locking plate, thereby locking the first connecting block and the second connecting block. When the handle drives the plug rod to rotate, the bevel on the plug rod opens the elastic locking plate to release the locked state.

[0010] Preferably, the inner wall of the locking sleeve is provided with threads for threaded connection with an external socket.

[0011] Preferably, the end of the tail sleeve is provided with a clamp for clamping the cable, and the clamp is tightened by a locking bolt.

[0012] Preferably, the quick-maintenance aviation plug assembly of the aircraft simulator also includes a sealing assembly disposed inside the tail sleeve.

[0013] Preferably, as a specific embodiment, the sealing assembly includes a sealing gasket, an annular spring, a sealing lip, and an O-ring.

[0014] Furthermore, the annular spring abuts against the sealing gasket to drive the sealing gasket and the sealing lip to press against the sidewall of the cable.

[0015] Furthermore, the O-ring is disposed around the inner ring of the sealing gasket at the point where it contacts the cable.

[0016] Preferably, the handle is integrally formed and connected to the exposed end of the plug.

[0017] This utility model has the following beneficial effects:

[0018] 1. In this utility model, by setting a disassembly and assembly assembly including a plug rod, an anti-disengagement block, a handle and an elastic locking plate between the plug body and the tail sleeve, the problem of cumbersome disassembly, time-consuming and inefficient maintenance of aviation plugs requiring tools is solved. The technical effect of quickly separating and locking the plug body and the tail sleeve without tools is achieved, greatly simplifying the maintenance process, shortening the maintenance time and improving the operation and maintenance efficiency.

[0019] 2. In this utility model, by setting a sealing assembly consisting of a ring spring, a sealing washer, a sealing lip, and an O-ring, the problems of the traditional plug sealing structure being simple, insufficient sealing reliability under vibration or temperature difference environments, and easy erosion by external moisture and dust are solved. It achieves multiple, dynamically compensated reliable sealing, effectively preventing contaminants from entering the plug, thereby enhancing the component's environmental adaptability and long-term working stability.

Detailed Implementation

[0027] 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.

[0028] Reference Figures 1-5The present invention provides an embodiment of a quick-maintenance aviation plug assembly for an aircraft simulator, comprising a plug body 2, a tail sleeve 4 coaxially disposed at the tail of the plug body 2, and a locking sleeve 3 rotatably sleeved on the outside of the plug body 2. The plug body 2 and the tail sleeve 4 are connected by a disassembly assembly 5 to achieve quick disassembly. The plug body 2 serves as the front end of the entire assembly and is used to house electrical connection elements such as pins. The tail sleeve 4 serves as the rear end of the assembly and is used to introduce and fix cables. The locking sleeve 3 is used to achieve mechanical locking of the entire assembly to the external socket 1.

[0029] The disassembly / assembly assembly 5 is the core structure for quickly separating and connecting the plug body 2 and the tail sleeve 4. It includes a first connecting block 501 fixedly connected to the plug body 2 and a second connecting block 505 fixedly connected to the tail sleeve 4. The first connecting block 501 is provided with a plug rod 502 that can be inserted into the second connecting block 505. The end of the plug rod 502 is provided with an anti-dislodgement block 503. The plug rod 502 is connected to the handle 504. The second connecting block 505 is provided with an elastic retaining plate 506. The outer circumferential surface of the plug rod 502 is provided with an inclined surface that cooperates with the elastic retaining plate 506. When the plug rod 502 is inserted into the second connecting block... At time 505, the front end of the anti-detachment block 503 will first contact and open the elastic plate 506. After the anti-detachment block 503 completely passes the elastic plate 506, the elastic plate 506 will rebound due to its own elasticity and lock onto the insertion rod 502, thereby firmly locking the first connecting block 501 and the second connecting block 505 together. When it is necessary to separate, the insertion rod 502 will be rotated by turning the handle 504. The inclined surface on the outer circumference of the insertion rod 502 will act on the elastic plate 506, opening it again and thus releasing the locking state. At this time, the insertion rod 502 can be pulled out from the second connecting block 505.

[0030] The inner wall of the locking sleeve 3 is provided with threads, which are used to connect with the corresponding external threads on the external socket 1. By rotating the locking sleeve 3, the axial fastening and circumferential positioning between the entire plug assembly and the socket 1 can be achieved, ensuring the stability of the electrical connection in a vibration environment.

[0031] To ensure a secure connection of the internal cables, the end of the tail sleeve 4 is equipped with a clamp 6 for clamping the cables. The clamp 6 is tightened by a locking bolt 7. When the locking bolt 7 is tightened, the inner diameter of the clamp 6 contracts, thereby generating a strong radial clamping force on the outer sheath of the cable, effectively preventing the cable from shifting due to external pulling or twisting, and protecting the welding or crimping points of the internal pins and the cable core.

[0032] To enhance the environmental adaptability of the entire component and prevent the intrusion of external pollutants, this embodiment also includes a sealing component 8. The sealing component 8 is disposed inside the tail sleeve 4, forming a complete seal for the internal space of the plug body 2 and the cable entry point. The sealing component 8 includes a sealing washer 801, an annular spring 802, a sealing lip 803, and an O-ring 804. The annular spring 802 abuts against the sealing washer 801. After the component is assembled, the annular spring 802 generates continuous axial pressure, driving the sealing washer 801 and the sealing lip 803 to press tightly against the side wall of the cable, forming the first dynamic seal. The O-ring 804 is arranged around the inner ring of the sealing washer 801 at the cable contact point. When the first connecting block 501 and the second connecting block 505 are locked by the disassembly and assembly component 5, the O-ring 804 is radially compressed, filling the gap between them, forming the second static seal. This dynamic and static sealing structure ensures excellent waterproof and dustproof performance.

[0033] To make the unlocking operation of the disassembly and assembly component 5 easier and more precise, the bevel on the outer circumference of the insertion rod 502 is machined into a curved surface with a specific helical angle. When the insertion rod 502 is rotated, the contact point between the curved surface and the elastic plate 506 will smoothly push the elastic plate 506 radially open, achieving an effortless unlocking process. To improve the convenience and ergonomics of operation, the handle 504 is integrally formed and connected to the exposed end of the insertion rod 502. The outer surface of the handle 504 is provided with knurling or anti-slip texture, so that maintenance personnel can firmly grip and rotate it even when wearing gloves or with oil stains. To further enhance the sealing reliability of the sealing component 8, the sealing gasket 801 is made of elastic rubber material. Its side facing the cable has an annular groove, which increases the contact area with the cable and the deformation compensation capability. The sealing lip 803 is integrally formed on the edge of the sealing gasket 801 and is inclined towards the cable direction to form a one-way sealing edge, which can better scrape off and block fluids or dust that attempt to enter.

[0034] Working principle: During the connection operation, first align the tail sleeve 4 with the cable and the plug body 2, and push the plug rod 502 on the first connecting block 501 into the second connecting block 505. During this process, the anti-disengagement block 503 at the head of the plug rod 502 will first open the elastic plate 506 inside the second connecting block 505. After the anti-disengagement block 503 has completely passed through, the elastic plate 506 automatically rebounds and locks into the groove or the back of the inclined surface of the plug rod 502, so as to quickly lock the plug body 2 and the tail sleeve 4. Then, align the entire plug assembly with the socket 1 on the device, and tighten the locking sleeve 3 by rotating it. The internal thread of the locking sleeve 3 and the external thread of the socket 1 are used to firmly tighten the two together. Tighten the locking bolt 7 at the end of the tail sleeve 4 to tighten the clamp 6 to hold and fix the cable.

[0035] When disassembly is required for maintenance, first turn the locking sleeve 3 counterclockwise to remove the plug assembly from the socket 1. Then, turn the handle 504 on the disassembly assembly 5 by hand. The handle 504 will drive the plug rod 502 to rotate synchronously. The inclined structure on the outer periphery of the plug rod 502 will push the elastic plate 506, causing it to be opened again, thereby releasing the lock on the anti-disengagement block 503. With a simple pull backward, the plug body 2 together with the first connecting block 501 can be separated from the tail sleeve 4 together with the second connecting block 505, exposing the pins and other components inside the plug body 2 for easy inspection or replacement. The whole process does not require disassembling the cable and clamps, achieving truly rapid maintenance.

[0036] Throughout the operation, the sealing assembly 8 continues to function. The preload generated by the annular spring 802 ensures that the sealing gasket 801 and the sealing lip 803 remain in close contact with the cable sheath. At the same time, the O-ring seal 804 fills the gap between the cable and the sealing gasket 801, together forming a reliable sealing barrier to prevent moisture and dust from entering the plug and ensuring the long-term reliability of the electrical connection.
