[0025] Reference is made to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the application proposes a connector for flight control system, which comprises a socket 1, a plug structure 2 arranged in the socket 1, a plug space 9 formed between the plug structure 2 and the inner wall of the socket 1, a rotation limiting groove 8 arranged on the inner wall of the socket 1, and a flexible block 11 arranged in the rotation limiting groove 8.

[0026] The socket 1 is the structural basis of the connector for flight control system, and other structures in the connector for flight control system are directly or indirectly mounted on the socket 1. The plug structure 2 on the socket 1 is used for inserting the plug 14. The plug 14 is also provided with a plug socket inserted into the plug space 9 and a rotation limiting vertical block 13 arranged on the outer periphery of the plug socket. The rotation limiting vertical block 13 is adapted to the rotation limiting groove 8, and by inserting the rotation limiting vertical block 13 into the rotation limiting groove 8, the angle of the plug 14 relative to the socket 1 is fixed. The flexible block 11 is the core component of the connector for flight control system. The rotation limiting vertical block 13 is provided with a limiting groove adapted to the flexible block 11. During the process of inserting the rotation limiting vertical block 13 into the plug space 9, the flexible block 11 deforms to enter the limiting groove of the rotation limiting vertical block 13.

[0027] Specifically, during the use of the connector for flight control system, a special plug 14 is needed. The plug 14 includes a plug-in part inserted into the plug structure 2, a plug socket, and a rotation limiting vertical block 13 arranged on the outer periphery of the plug socket. The rotation limiting vertical block 13 is provided with a limiting groove. When the plug-in part of the plug 14 is inserted into the plug structure 2, the plug socket of the plug 14 is also inserted into the plug space 9, and the rotation limiting vertical block 13 is also inserted into the corresponding rotation limiting groove 8. The angle of the plug 14 relative to the socket 1 is limited by the cooperation of the limiting vertical block and the limiting groove. As the rotation limiting vertical block 13 is inserted into the rotation limiting groove 8 and contacts the flexible block 11, the flexible block 11 also starts to deform under the action of the rotation limiting vertical block 13. When the end of the rotation limiting vertical block 13 contacts the bottom surface of the rotation limiting groove 8, the flexible block 11 enters the limiting groove. The cooperation of the flexible block 11 and the limiting groove avoids the plug 14 from being separated from the socket 1, thereby improving the reliability of the electrical connection between the plug 14 and the socket 1 and ensuring the stability of the connector for flight control system.

[0028] In detail, the flexible block 11 is made of nylon material, and the cross-sectional area of the end of the rotation limiting vertical block 13 to the limiting groove is smaller than the cross-sectional area of the rotation limiting groove 8. The above structure design is conducive to the insertion of the rotation limiting vertical block 13 into the rotation limiting groove 8, and the gap between the rotation limiting vertical block 13 and the rotation limiting groove 8 also provides space for the deformation of the flexible block 11, avoiding the difficulty of inserting the plug 14 into the socket 1.

A second guide portion 111, both vertical sides of the limiting groove 8 are provided with the second guide portion 111, the second guide portion 111 is conducive to the flexible block 11 entering the limiting groove of the limiting vertical block 13, and is conducive to the flexible block 11 leaving the limiting groove of the limiting vertical block 13.

[0030] In this embodiment, in order to reduce the difficulty of alignment, the end of the socket cylinder 1 and the end of the splicing structure 2 are both provided with a third guide portion, which is conducive to reducing the difficulty of inserting the plug 14 into the socket cylinder 1. The first guide portion 10, the second guide portion 111 and the third guide portion are all preferably arc surfaces, which is conducive to reducing stress concentration.

After the threaded sleeve is screwed to the bottom, it abuts against the abutting platform 7, and the threaded sleeve is locked by the friction force between the threaded sleeve and the abutting platform 7, so as to avoid loosening of the threaded sleeve and affect the reliability of the connection between the plug 14 and the socket cylinder 1.

[0032] In this embodiment, the plug 14 is provided with a limiting portion for limiting the threaded sleeve from coming out, one end of the threaded sleeve is open, the other end is provided with a through hole, the outer diameter of the limiting portion is greater than the inner diameter of the threaded sleeve through hole, so that the threaded sleeve cannot come out of the plug 14 from the end provided with the limiting portion. After the threaded sleeve is screwed onto the socket cylinder 1, an elastic clamp can be clamped on the plug 14, and the position of the threaded sleeve relative to the plug 14 is limited by the elastic clamp and the limiting portion.
