[0009] The technical solution of the present invention is:

[0010] A blind-mate docking device capable of adaptive adjustment comprises a mounting backplane, a connector mounting plate, and a blind-mate connector;

[0011] The blind-mate connector is fixedly connected to the connector mounting plate;

[0012] A through mounting hole is provided in the middle of the mounting back plate, and an angle floating device is connected to the mounting hole of the mounting back plate so that the angle floating device and the mounting back plate can be rotated at an angle, thereby adjusting the rotation deviation;

[0013] A radial floating device is connected between the angle floating device and the connector mounting plate, so that the connector mounting plate can move with tolerance in a direction perpendicular to the mounting plane of the angle floating device and the connector mounting plate.

[0014] The angle floating device includes a rotating inner ring, which is rotationally connected to the mounting back plate.

[0015] The angle floating device also includes at least one rotating outer ring;

[0016] When one rotating outer ring is provided, the rotating inner ring is rotatably connected to the rotating outer ring, the rotation axis of the rotating inner ring is parallel to the rotating outer ring, the rotating outer ring is rotatably connected to the mounting back plate, the rotation axis of the rotating outer ring is parallel to the mounting back plate, and the rotation axes of the rotating inner ring and the rotating outer ring are not parallel;

[0017] When multiple rotating outer rings are provided, the rotating outer rings are sequentially connected to each other, and among two adjacent rotating outer rings, the inner rotating outer ring is rotationally connected to the outer rotating outer ring, and the rotating inner ring is rotationally connected to the inner side of the innermost rotating outer ring, and the rotation axes of different rotating outer rings are not parallel;

[0018] There is a gap between the rotating inner ring and the rotating outer ring, and there is a gap between the rotating outer ring and the edge of the mounting hole of the mounting back plate.

[0033] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0034] The present application discloses a blind-mating docking device that can be adjusted adaptively. Figure 1 and Figure 2 As shown, it includes a mounting backplate 1, a connector mounting plate 5, a blind-plug connector 6, a rotating inner ring 3, a rotating outer ring 2, and a radial floating device.

[0035] A through hole is opened in the middle of the connector mounting plate 5 , and the blind-plug connector 6 passes through the through hole and is connected to the connector mounting plate 5 by bolts, thereby achieving a fixed connection between the blind-plug connector 6 and the connector mounting plate 5 .

[0036] like Figure 1As shown, a through-hole is provided in the middle of the mounting backplate 1. The rotating outer ring 2 is rotatably connected to the mounting hole of the mounting backplate 1. The rotating inner ring 3 is rotatably connected to the inner side of the rotating outer ring 2. The rotation axis of the rotating inner ring is parallel to the rotating outer ring 2, the rotation axis of the rotating outer ring 2 is parallel to the mounting backplate 1, and the rotation axis of the rotating inner ring 3 is perpendicular to the rotation axis of the rotating outer ring 2. The rotation axes of the rotating inner ring 3 and the rotating outer ring 2 are respectively the X-axis and the Y-axis, and there is a gap between the rotating inner ring 3 and the rotating outer ring 2, and between the rotating outer ring 2 and the mounting backplate 1. By controlling the size of the gap, the angular range of rotation between the rotating inner ring 3 and the rotating outer ring 2 can be controlled. Ultimately, the blind-mate connector 6 installed on the connector mounting plate 5 has adaptive adjustment functions in the X and Y directions, and can achieve adaptive adjustment functions with rotation deviations of less than ±1° on the X and Y axes.

[0037] like Figure 2 As shown, the radial floating device includes a connecting hole, a fixing screw 8, a rubber sleeve 7, and a support sleeve. The connecting hole is provided on the connector mounting plate 5, and the fixing screw 8 passes through the connecting hole and is threadedly connected to the angular floating device. The inner diameter of the connecting hole is larger than the outer diameter of the fixing screw 8. By controlling the difference between the inner diameter of the connecting hole and the outer diameter of the fixing screw 8, the tolerance range of the connector mounting plate 5 in the radial direction of the fixing screw 8 can be controlled. In this embodiment, position adjustment of less than ±1mm can be achieved. The rubber sleeve 7 is connected between the connecting hole and the fixing screw 8 to provide a certain support force for the connector mounting plate 5, so that the connector mounting plate 5 can be positioned in the middle of the connection hole in its natural state. Since the rubber sleeve 7 is an elastomer, when there is an error in the docking of the blind-mate connector 6 and the connector mounting plate 5 needs to be moved, the connector mounting plate can still move in the radial direction of the fixing screw 8. The support sleeve is connected to the inner side of the rubber sleeve 7, and a mounting platform is connected to the side of the support sleeve facing the angle floating device. The height of the support sleeve along the axial direction of the fixing screw 8 is greater than the thickness of the connector mounting plate 5, so that after the fixing screw 8 is tightened, the fixing screw 8 presses the support sleeve onto the rotating inner ring 3, and the fixing screw 8 does not press the connector mounting plate 5. There is a gap between the angle floating device and the connector mounting plate 5, which ensures that the connector mounting plate 5 can float radially.

[0038] A buffer reset device may also be provided between the rotating inner ring 3 and the rotating outer ring 2, and between the rotating outer ring 2 and the mounting backplate 1. The buffer reset device may be a torsion spring, one end of which is fixedly connected to the rotating shaft of the rotating inner ring 3 and the other end is fixedly connected to the rotating outer ring 2, and / or one end of which is fixedly connected to the rotating shaft of the rotating outer ring 2 and the other end is fixedly connected to the mounting backplate 1. The buffer reset device may also be an elastic flexible mounting portion, the flexible mounting portion being fixedly connected to the outside of the rotating inner ring 3 or the inside of the rotating outer ring 2, and / or the flexible mounting portion being fixedly connected to the outside of the rotating outer ring 2 or the inside of the mounting hole of the mounting backplate 1. This ensures that the rotating inner ring 3 and the rotating outer ring 2 are stably parallel to the mounting backplate 1 in their natural state, and prevents jamming between the rotating inner ring 3 and the rotating outer ring 2, and between the rotating outer ring 2 and the mounting backplate 1.

[0039] The connector of the present application is bidirectionally adaptive and blind-mateable, and is suitable for installation methods of all blind-mate connectors.

[0040] Although the present invention is disclosed above in terms of preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art may make possible changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined by the claims of the present invention.
