DETAILED DESCRIPTION

[0029] In order to make the purpose, technical scheme and advantages of the utility model embodiments clearer, the technical scheme in the utility model embodiments will be described clearly and completely below in combination with the drawings in the utility model embodiments.

[0030] This application provides an aviation plug junction box, primarily addressing the problems of existing junction boxes, which typically connect multiple different aviation plugs. Due to the lack of an effective wire management mechanism, the wires inside the junction box are often messy and disorganized, increasing the risk of short circuits and poor contact, and making maintenance work complex and time-consuming. Secondly, existing junction boxes are unsatisfactory in preventing dust and moisture intrusion, which is crucial for maintaining equipment performance in variable environments. Furthermore, existing junction boxes are inadequate in securing plug wires and facilitating quick operation; plug wires are prone to loosening or detachment. When maintaining a single aviation plug, the entire junction box needs to be opened, exposing all aviation plugs to the outside environment, increasing risk and operational complexity. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-5 Please provide a detailed explanation:

[0031] An aviation plug junction box mainly includes an aviation plug body 1, a junction box body 2, and a reinforcing mechanism 3, wherein:

[0032] The aircraft plug body 1 consists of a male contact 11 and a female contact 12, which are electrically connected by mating to ensure stable transmission of electrical signals and energy. Wires 13 are connected to both the male contact 11 and the female contact 12 to provide necessary electrical connections for the electronic equipment inside the aircraft.

[0033] The junction box body 2 is formed by the upper box body 21 and the lower box body 22. Both opposite ends of the junction box body 2 have through holes 23. Two wires 13 pass through the two through holes 23 respectively. The wires 13 fit snugly with the through holes 23 to ensure sealing. The through holes 23 are formed by the mating of two semi-circular holes 231. The two semi-circular holes 231 are respectively constructed on the upper box body 21 and the lower box body 22, which facilitates installation and enhances the sealing performance of the junction box, effectively preventing dust and moisture from entering. The upper box body 21 is equipped with a fixing member 24 for fixing the upper box body 21 and the lower box body 22, and the lower box body 22 is equipped with a releasing member 25 for releasing the fixing. This design simplifies the opening and closing process of the junction box and facilitates quick plugging and unplugging and maintenance.

[0034] The number of reinforcement mechanisms 3 is multiple and evenly distributed. Each reinforcement mechanism 3 consists of two symmetrically arranged clamping members. The two clamping members are respectively installed on the inner wall of the upper box 21 and the inner wall of the lower box 22. The two clamping members clamp and fix the wire 13 to prevent the wire 13 from loosening or falling off under the vibration or impact of the aircraft, thereby improving the structural stability and durability of the junction box body 2.

[0035] In terms of operation, the operator can easily open and close the terminal box body 2 through the fixing member 24 and the releasing member 25 to perform the plugging and maintenance work of the wire 13. The design of the reinforcing mechanism 3 makes the wire 13 management more orderly, and reduces the risk and the complexity of operation during maintenance.

[0036] The aviation plug terminal box of the present scheme significantly improves the wire 13 management efficiency, reduces the risk of short circuit and poor contact, and at the same time, the sealing performance of the terminal box is enhanced, effectively protecting the internal electrical connection from the influence of harsh environment. In addition, the convenience of quick operation and maintenance is also optimized, reducing the risk and complexity of operation during maintenance, suitable for aircraft electrical systems in variable environments.

[0037] In the aviation plug terminal box of the present scheme, the design and arrangement of the fixing member 24 is the key to realize the quick and stable connection between the upper box body 21 and the lower box body 22. For details, please refer to Figure 3 、 Figure 4 and Figure 5 The number of fixing members 24 is two and symmetrically arranged, which ensures the stability and symmetry of the terminal box. The fixing member 24 includes a fixing rod 241 fixed on the inner wall of the upper box body 21. One end of the fixing rod 241 penetrates the opening of the upper box body 21 and is fixed with a fixing block 242. The fixing rod 241 and the fixing block 242 are arranged in "L" shape. The fixing block 242 is away from the side of the opening end of the upper box body 21 and is configured as a curved surface. The inner wall of the lower box body 22 is configured with a fixing groove 221 corresponding to the fixing block 242. When the upper box body 21 and the lower box body 22 are relatively closed, the end of the fixing block 242 away from the fixing rod 241 is movably clamped in the inside of the fixing groove 221. The curved surface design helps to improve the tightness between the fixing block 242 and the fixing groove 221, and enhances the stability of the overall structure.

[0038] This fixing method not only simplifies the assembly and disassembly process of the terminal box body 2, but also improves the stability of the terminal box body 2 when subjected to external impact, ensuring the safety of the internal electrical connection. Through the design of the fixing member 24, the upper box body 21 and the lower box body 22 of the terminal box body 2 can be quickly and reliably fixed, while ensuring the sealing performance and durability of the terminal box in various environments, which is crucial for the stable operation of the internal electrical system of the aircraft.

[0039] Please refer to Figure 3 、 Figure 4 and Figure 5The fixed groove 221 penetrates the lower box body 22, the releasing part 25 comprises a pressing block 251 movably inserted into the fixed groove 221, one end of the pressing block 251 is fixed with a pressing plate 252, the pressing plate 252 is designed to facilitate the pressing operation of the operator, and the pressing block 251 can be moved in the fixed groove 221 by applying force through the pressing plate 252, thereby realizing the quick release of the upper box body 21 and the lower box body 22. The pressing block 251 is moved by the pressing plate 252, and the fixed block 242 is moved by the pressing block 251, at this time, the fixed rod 241 is deformed by a certain amount, until the fixed block 242 is separated from the fixed groove 221, at this time, two hands pull the upper box body 21 and the lower box body 22 respectively, and the upper box body 21 and the lower box body 22 can be separated.

[0040] Further, the inner wall of the fixed groove 221 is provided with a limiting groove 222, and the pressing block 251 is fixed with a limiting block 253 sliding in the limiting groove 222. This sliding mechanism enables the pressing block 251 to maintain the correct position and direction when moving in the fixed groove 221, preventing the pressing block 251 from shifting or moving during operation, ensuring the accuracy and consistency of the release operation, and avoiding the pressing block 251 from separating from the fixed groove 221.

[0041] In the aviation plug junction box of the present application, in order to enhance the stability and durability of the overall structure, please refer to Figure 2 and Figure 4 The opening end of the lower box body 22 is fixed with a stabilizing plate 223, and the inner side of the opening end of the upper box body 21 is provided with a stabilizing groove 211 corresponding to the stabilizing plate 223. The stabilizing plate 223 is movably inserted into the stabilizing groove 211, and the cooperation of the stabilizing plate 223 and the stabilizing groove 211 not only enhances the connection stability of the whole, but also provides a buffering mechanism to absorb and reduce the vibration and impact generated during the operation of the aircraft, and improves the sealing between the upper box body 21 and the lower box body 22, avoiding dust and water vapor from entering.

[0042] In the aviation plug junction box of the present application, the design of the clamping part is crucial to ensure the stable fixation of the wire 13, please refer to Figure 2 and Figure 4The clamping piece includes a mounting cylinder 31 fixed on the inner wall of the upper box body 21 or the inner wall of the lower box body 22, one end of the mounting cylinder 31 movably inserts a mounting rod 32, the mounting rod 32 is fixed with a semicircular clamping plate 33 at one end, and the semicircular design enables the clamping plate 33 to closely fit the shape of the wire 13, providing uniform and stable clamping force. The opening of the clamping plate 33 faces away from the mounting rod 32, and the side of the clamping plate 33 away from the opening is connected with the spring 34 sleeved outside the mounting cylinder 31 between the inner wall of the upper box body 21 or the inner wall of the lower box body 22. The design of the spring 34 provides the necessary elasticity for the clamping piece, so that the clamping plate 33 can adapt to wires 13 of different sizes and maintain constant clamping pressure, preventing the wire 13 from loosening due to vibration or impact.

[0043] When the upper box body 21 and the lower box body 22 are closed, the openings of the two corresponding clamping plates 33 face each other. With the fixing piece 24 fixing the upper box body 21 and the lower box body 22, the two clamping pieces clamp and fix the wire 13. The plurality of reinforcing mechanisms 3 can effectively ensure the stability of the connection between the male contact piece 11 and the female contact piece 12.

[0044] Please refer to Figure 4 and Figure 5 The hole wall of the semicircular hole 231 is fixed with a rubber sealing gasket 232, which ensures that when the upper box body 21 and the lower box body 22 are closed, the threading hole 23 can provide good sealing effect. This sealing design effectively prevents dust, water vapor and other external pollutants from entering, protecting the electrical connection inside the terminal box body 2 from environmental factors. Especially in the variable aviation environment, this sealing performance is crucial to maintaining the reliability and stability of the equipment.

[0045] In addition, the outside of the terminal box body 2 is specially provided with a label, which is a detail design that allows each terminal box body 2 to be clearly identified and classified, facilitating quick identification and tracking during maintenance, repair or replacement. The label provides a convenient location to record relevant information such as model, date, maintenance record, etc., thereby improving the management efficiency of the terminal box and the accuracy of the maintenance work. This design not only enhances the traceability of the terminal box, but also provides convenience for the maintenance of the electrical system inside the aircraft.

[0046] The following is a description of the specific installation and disassembly operations of the terminal box:

[0047] Installation operation:

[0048] First, the male contact piece 11 and the female contact piece 12 of the aviation plug body 1 are inserted to achieve electrical connection;

[0049] Then, the two wires 13 are respectively corresponding to the threading holes 23 at both ends of the terminal box body 2, the threading holes 23 are composed of two semicircular holes 231, which are respectively located on the upper box body 21 and the lower box body 22, to ensure that the wires 13 are attached to the threading holes 23 to maintain the sealing property;

[0050] The upper box body 21 and the lower box body 22 are closed, and in this process, the fixing member 24 fixes the upper box body 21 and the lower box body 22 to ensure the stability of the connection;

[0051] When the upper box body 21 and the lower box body 22 are closed, the clamping plate 33 in the reinforcing mechanism 3 clamps and fixes the wires 13 to prevent the wires 13 from loosening or falling off under the vibration or impact of the aircraft.

[0052] Dismounting operation:

[0053] Firstly, the pressing operation is performed by the releasing member 25, i.e. the pressing block 251, and the design of the pressing plate 252 enables the operator to easily exert force to move the pressing block 251 in the fixing groove 221;

[0054] The movement of the pressing block 251 pushes the fixing block 242, causing a certain deformation of the fixing rod 241, until the fixing block 242 is separated from the fixing groove 221;

[0055] After the fixing block 242 is separated from the fixing groove 221, the operator pulls the upper box body 21 and the lower box body 22 respectively to realize the separation of the two.

[0056] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the technical field according to the technical scheme and the application concept of the present application within the technical range disclosed by the present application can be equivalently replaced or changed, which should be covered in the protection scope of the present application.
