[0021] This application provides a radial floating self-resetting blind mating device.

[0022] like Figure 1 and Figure 2 As shown, a radial floating self-resetting blind mating device includes: Guide sleeve 1 is fixed to the outer periphery of the socket on the airborne bracket. The inner wall of the end of the guide sleeve 1 facing away from the tail of the socket is flared.

[0023] The floating component 2 includes a mounting frame and an annular limiting component. The mounting frame is used to install the floating component 2 on a load that docks with an airborne rack. The annular limiting component is used to install a plug 3 that docks with the socket. The plug 3 has an annular groove structure on its outer peripheral sidewall. The annular limiting component surrounds the annular groove structure, and the end face of the annular limiting component perpendicular to the length direction of the plug 3 is used to avoid contact with the inner side of the annular groove structure. The plug 3 is movably disposed within the annular limiting component, and the direction of movement of the plug 3 is perpendicular to the length direction of the plug 3.

[0024] The floating component 2 of this application provides a certain amount of radial movement range for the plug 3 when it is connected to the load. When docking the plug 3 and the socket, under the guidance of the flared structure of the guide sleeve 1, the plug 3 can move radially to align the plug 3 and the socket, which improves the efficiency and success rate of docking the plug 3 and the socket, reduces the risk of damage to the connector when docking the plug 3 and the socket, and ensures the stability of signal transmission.

[0025] The radial floating self-resetting blind mating device also includes a convex ring 31 and a retaining ring 32. The convex ring 31 and the outer periphery of the plug 3 are fixedly connected. The retaining ring 32 is located at the tail of the plug 3. The area between the retaining ring 32 and the convex ring 31 forms the annular groove structure for accommodating the annular limiting component. The annular limiting component includes a mounting plate 22 and a plurality of spring top beads 21. The mounting plate 22 is located at the tail of the plug 3 and is located on the side of the retaining ring 32 facing the convex ring 31. The spring top beads 21 are installed on the side of the mounting plate 22 facing away from the retaining ring 32. The mounting plate 22 and the spring top beads 21 are located between the convex ring 31 and the retaining ring 32. The tail of the plug 3 is provided with a locking block 33, which is used to abut against the side of the retaining ring 32 facing away from the mounting plate 22.

[0026] The mounting plate 22 has a through hole 23 for the cable of the plug 3 to pass through. Several spring top beads 21 are distributed circumferentially along the through hole 23. The springs of the spring top beads 21 are arranged radially along the plug 3. In this application, there are six spring top beads 21, which are divided into two groups. The two groups of spring top beads 21 are symmetrically arranged about the axis of the plug 3. The opening of the groove 34 is a closed and centrally symmetrical arc. The inner wall of the groove 34 is a smooth curved surface that is deeper inside and shallower outside. The length of the shortest line segment of the opening contour of the groove 34 passing through the center of symmetry is greater than the diameter of the top bead of the spring top bead 21. The top bead of the spring top bead 21 abuts in the groove 34. When the springs of all the spring top beads 21 are in the maximum compressed state, the radius of the circle formed by the top beads of all the spring top beads 21 is greater than the radius of the circle formed by the bottom of all the grooves 34. In this embodiment, the opening profile of the groove 34 is elliptical, and the elliptical opening profile is curved along the circumferential outer wall of the plug 3. The major semi-axis of the elliptical opening is perpendicular to the axis of the plug 3, and the length of the minor semi-axis of the elliptical opening is greater than the radius of the top bead. The inner wall surface of the groove 34 is spherical.

[0027] The spring ball 21 abuts against the groove 34 to stabilize the plug 3 in the initial position. When the plug 3 and the socket are connected, if the plug 3 cannot be aligned with the socket, the plug 3 will shift to one side to compress the spring of the spring ball 21. The spring of the spring ball 21 on the opposite side of the compressed spring ball 21 will extend. All the spring balls 21 can stably abut against the annular groove structure to ensure a stable connection between the plug 3 and the load.

[0028] The retaining ring 32 has a tail cover 35 on the side opposite to the plug end of the plug 3. The tail cover 35 has an opening on the side parallel to the length direction of the plug 3 for the cable of the plug 3 to pass through.

[0029] The mounting plate 22 has mounting ears 24 at opposite ends. The mounting ears 24 serve as the mounting bracket for mounting the floating component 2 onto the load that docks with the airborne rack.

[0030] like Figure 3 and Figure 4 As shown, the guide sleeve 1 includes a connecting sleeve 11 and a guide sleeve 12. The connecting sleeve 11 is used for fixed connection with the socket. One end of the guide sleeve 12 extends into the connecting sleeve 11, and the other end of the guide sleeve 12 extends out of the connecting sleeve 11. The outer diameter of the end of the guide sleeve 12 extending out of the connecting sleeve 11 is greater than or equal to the outer diameter of the connecting sleeve 11. The guide sleeve 12 extends into the connecting sleeve 11 and has a first annular groove 13 on its outer wall. The connecting sleeve 11 has a second annular groove 14 corresponding to the first annular groove 13 on its inner wall. A retaining spring 17 is provided between the guide sleeve 12 and the connecting sleeve 11, and the retaining spring 17 is located in the first annular groove 13 and the second annular groove 14.

[0031] The guide sleeve 12, near the end of the socket, has the same inner diameter as the connecting sleeve 11, forming a cylindrical inner wall. The inner diameter of the guide sleeve 12 gradually increases from the middle to the end extending out of the connecting sleeve 11, forming a tapered inner wall. The tapered inner wall is used to guide the docking of the plug 3 and the socket.

[0032] The inner wall of the guide sleeve 12 is provided with a positioning groove 15 that mates with the positioning key on the outer wall of the plug end of the plug 3. A portion of the positioning groove 15 is located on the conical inner wall, and another portion is located on the cylindrical inner wall. The end face of the portion of the guide sleeve 12 extending out of the connecting sleeve 11 is provided with a conical notch 16 that communicates with the positioning groove 15. The width of the smaller end of the conical notch 16 is greater than or equal to the width of the positioning groove 15. The conical notch 16 facilitates the docking of the positioning key and the positioning groove 15. Furthermore, in this embodiment, the front section of the positioning key is also conical.

[0033] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
