When using the testing device for the 1553B bus, the first cable and the second cable are connected by a socket and a connector. This not only makes the internal connection more convenient, but also prevents the internal connecting wires from becoming tangled after connection. At the same time, the cooperation between the first connecting tube and the second connecting tube can easily protect the connected cables and prevent poor contact or detachment due to contact.

[0004] However, during the use of the above equipment, it was found that the threaded connection needs to be screwed in one turn at a time.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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] Example 1:

[0024] Please see Figures 1-4This utility model provides an avionics bus test platform, including a processor 1 and a coupler 2. A first threaded hole 14 is provided on one side of the processor 1, and a mounting bracket 3 is installed on the first threaded hole 14 by bolts. Connecting brackets 21 are fixedly provided at both ends of the bottom of the coupler 2, and connecting holes 22 are provided on the connecting brackets 21. An L-shaped fixing bracket 31 is fixedly installed on the mounting bracket 3. A push plate 32 is provided between the fixing bracket 31 and the mounting bracket 3. Positioning rods 323 are fixedly installed at the top of both ends of the push plate 32. The positioning rods 323 pass through the mounting bracket 3 and are adapted to the connecting holes 22. Guide rods 324 are fixedly installed at the bottom of both ends of the push plate 32. The guide rods 324 pass through the fixing bracket 31. Springs 33 are provided around the guide rods 324. The two ends of the springs 33 are respectively connected to the push plate 32 and the fixing bracket 31. A pull rod 321 is fixedly provided at the bottom of the push plate 32. The pull rod 321 passes through the fixing bracket 31 and is connected to the pull handle 322.

[0025] Specifically, when installing the coupler 2, align the mounting bracket 3 on the processor 1 with the connecting bracket 21 at the bottom of the coupler 2, so that the positioning rod 323 is aligned with the connecting hole 22. Then pull the handle 322. The handle 322 drives the push plate 32 to move downward through the pull rod 321. At this time, the spring 33 is compressed, and the positioning rod 323 is pulled out downward from the mounting bracket 3. When the positioning rod 323 is fully aligned with the connecting hole 22, release the handle 322. The spring 33 returns to its elastic deformation, pushes the push plate 32 to move upward, and then inserts the positioning rod 323 into the connecting hole 22, thus completing the installation of the coupler 2 and the processor 1.

[0026] When disassembling coupler 2, pull handle 322. Pull handle 322 drives push plate 32 to move downward through pull rod 321. Spring 33 is compressed, and positioning rod 323 is pulled out from connection hole 22. After positioning rod 323 is completely pulled out from connection hole 22, the connecting bracket 21 of coupler 2 is separated from mounting bracket 3 on processor 1, and the disassembly of coupler 2 can be completed. Installation and disassembly can be completed by pulling and releasing handle 322, which greatly saves operation time and improves work efficiency.

[0027] Furthermore, to improve the stability of coupler 2 and protect the cable connection, please refer to [link / reference needed]. Figures 1-4 The coupler 2 has a second threaded hole 23 equidistantly opened on one side, and a first cable 24 is connected inside the second threaded hole 23. A connector 25 is provided at one end of the first cable 24.

[0028] A first sleeve 26 is installed in the second threaded hole 23. A first threaded tube 262 is provided at one end of the first sleeve 26. The first sleeve 26 is spirally connected to the second threaded hole 23 through the first threaded tube 262. A first rotating frame 261 is fixedly provided on the first sleeve 26.

[0029] A third threaded hole 11 is provided at equal intervals on one side of the processor 1. A second cable 12 is connected inside the third threaded hole 11. One end of the second cable 12 is provided with a connector 13, which is correspondingly adapted to the connector 25.

[0030] A second sleeve 15 is installed in the third threaded hole 11. A second threaded tube 152 is provided at one end of the second sleeve 15. The second sleeve 15 is spirally connected to the third threaded hole 11 through the second threaded tube 152. A second rotating frame 151 is provided on the second sleeve 15.

[0031] The outer diameter of the second sleeve 15 is compatible with the inner diameter of the first sleeve 26.

[0032] Specifically, when coupler 2 is connected to processor 1, the connector 25 on the first cable 24 is connected to the connector 13 on the second cable 12. At this time, the second threaded tube 152, which is spirally connected in the third threaded hole 11, is inserted into the first threaded tube 262. The outer diameter of the second sleeve 15 matches the inner diameter of the first sleeve 26, and the two cooperate with each other during connection. This not only enables coupler 2 and processor 1 to be more precisely aligned and ensures accurate docking of connector 13 and connector 25, but also further enhances the stability of the connection. Combined with the cooperation of positioning rod 323 and connecting hole 22, the stability of coupler 2 is improved from multiple dimensions.

[0033] The sheath encloses the cable, preventing external mechanical damage such as friction, compression, and impact. It also prevents damage to the outer sheath caused by friction with other components, thus protecting the internal core wires. Furthermore, when the cable is subjected to tensile or torsional forces, the sheath distributes these forces across its entire surface, rather than concentrating them at the cable connection points. This effectively reduces stress at the cable connection points, preventing excessive stress from causing the internal core wires to break or the connection points to loosen.

[0034] Working principle: Connect the first sleeve 26 in the second threaded hole 23 on one side of the coupler 2 to the second sleeve 15 in the third threaded hole 11 on the side of the processor 1, so that the second threaded tube 152 is inserted into the first threaded tube 262. By utilizing the matching relationship between the second sleeve 15 and the first sleeve 26, the connector 13 and the connector 25 are accurately aligned to complete the electrical connection. Then, align the mounting bracket 3 on the processor 1 with the connecting bracket 21 at the bottom of the coupler 2, so that the positioning rod 323 is aligned with the connecting hole 22. Then pull the handle 322. The handle 322 drives the push plate 32 to move downward through the pull rod 321, compressing the spring 33, so that the positioning rod 323 is pulled out downward from the mounting bracket 3. When the positioning rod 323 is completely aligned with the connecting hole 22, release the handle 322. The spring 33 returns to its elastic deformation, pushing the push plate 32 to move upward, so that the positioning rod 323 is inserted into the connecting hole 22, thus completing the mechanical installation and fixation of the coupler 2 and the processor 1.

[0035] After the coupler 2 and processor 1 are installed and connected, the avionics bus test platform can be put into use. The processor 1 controls and utilizes the coupler 2 to perform various test tasks on the avionics bus, such as signal transmission testing and data communication testing. When the test is completed and the coupler 2 needs to be disassembled, pull the handle 322. The handle 322, through the pull rod 321, moves the push plate 32 downwards, compressing the spring 33, and pulling the positioning rod 323 out of the connection hole 22. After the positioning rod 323 is completely pulled out of the connection hole 22, separate the connecting bracket 21 of the coupler 2 from the mounting bracket 3 on the processor 1 to complete the disassembly of the coupler 2.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
