The second plug structure 20 includes a second housing 21, a second plug 22 movably disposed on the second housing 21, and a driving member 23 for driving the second plug 22 to move. The first locking member 30 is movably disposed on the driving member 23, the second seat 21 is provided with a first engaging portion, and the first locking member 30 is movably disposed so that the first locking member 30 has a first locking position where the first locking member is locked and engaged with the first engaging portion and a first unlocking position where the first locking member is separated from the first engaging portion. In the present embodiment, the driving member 23 drives the second connector 22 to move so that the second connector 22 has a connection position for being plugged into the first connector 12 and a disconnection position for being separated from the first connector 12, and when the second connector 22 is located at the connection position, the first locking member 30 can move from the first unlocking position to the first locking position to maintain the second connector 22 at the connection position. When the second connector 22 and the first connector 12 are at the connection position of the plugging, the first plugging structure 10 is communicated with the second plugging structure 20, so that the two boxes are further communicated, and finally, the power supply communication and the signal transmission of the LED display device are realized.

By applying the technical solution of this embodiment, the first plug structure 10 can be installed on one adjacently disposed box, and the second plug structure 20 can be installed on the other adjacently disposed box.

The second connector 22 is linearly movable, and the first lock 30 is linearly movable.

As shown in fig. 3 and 9, the first locking member 30 includes a first locking post 31, and the first fitting portion includes a first fitting hole 211 corresponding to the first locking post 31. Thus, the first locking column 31 can penetrate into the first engagement hole 211, and the first locking member 30 can move from the first unlocking position to the first locking position. The first locking column 31 is matched with the first matching hole 211, so that the first locking piece 30 is convenient to use and reliable in locking.

The convex-concave contact structure comprises an arc-shaped convex part 221 and a concave part 232 wrapped on the arc-shaped convex part 221, and the concave part 232 rotates around the arc-shaped convex part 221 so that the driving piece 23 drives the second plug connector 22 to move. In this way, the arc-shaped protrusion 221 can support the driving member 23, and the arc-shaped protrusion 221 can form a rotation path of the recess 232, so that the driving member 23 can smoothly and directly drive the second connector 22 to move. Thus, the second plug structure 20 is simple in structure and convenient to drive.

Specifically, pressing the upper end of the recess 232 causes the recess 232 to rotate counterclockwise around the arc-shaped protrusion 221, the driving member 23 drives the second connector 22 to move downward, so that the second connector 22 is switched from the connection position to the disconnection position, pressing the lower end of the recess 232 causes the recess 232 to rotate clockwise around the arc-shaped protrusion 221, and the driving member 23 drives the second connector 22 to move upward, so that the second connector 22 is switched from the disconnection position to the connection position.

As shown in fig. 2, 4 and 9, the arcuate projection 221 is provided on the second plug 22, and the recess 232 is provided on the driver 23.

The driving member 23 is rotatably connected to the corresponding stand block 224 by a rotating shaft 233. The first locking member 30 moves in a direction parallel to the axis of the shaft 233, and the second plug 22 moves in a direction perpendicular to the axis of the shaft 233. The two standing blocks 224 are arranged to limit the movement of the driving member 23 along the axial direction of the rotating shaft 233, so as to limit the driving member 23 between the two standing blocks 224. Meanwhile, the rotation shaft 233 is provided to limit the driving member 23 to the two upright blocks 224, so that the recess 232 of the driving member 23 can only rotate around the arc-shaped protrusion 221.

As shown in fig. 2 to 4, the number of the rotating shafts 233 is two, the driving member 23 is preferably a driving block, the two rotating shafts 233 are located at two opposite sides of the driving block, and each of the upright blocks 224 is provided with a first half hole. The second plug structure 20 further comprises a baffle 25 connected to each of the uprights 224. The baffle 25 is provided with a second half hole corresponding to the first half hole, the first half hole and the second half hole form a round hole together, and a rotating shaft 233 penetrates into the round hole. The setting of baffle 25 can be with pivot 233 restriction in the round hole, prevents that pivot 233 from dropping from corresponding upright piece 224, and then in second plug connector 22 removes the in-process, and driving piece 23 can remove along with second plug connector 22 for driving piece 23 drive second plug connector 22 removes convenience more.

As shown in fig. 4 to 8, the second plug structure 20 further includes an elastic member 24 disposed between the second housing 21 and the second plug 22. In the process that the driving part 23 drives the second connector 22 to move so that the second connector 22 is switched from the disconnection position to the connection position, the elastic part 24 plays a damping role, so that the second connector 22 can be smoothly connected with the first connector 12, and the damage to the internal structure (such as a pin) of the second connector 22 or the first connector 12 caused by too fast connection is avoided. In the process that the driving part 23 drives the second plug connector 22 to move so that the second plug connector 22 is switched from the connection position to the disconnection position, the elastic part 24 provides a thrust force, so that the second plug connector 22 can be quickly separated from the first plug connector 12, which is beneficial to improving the plugging efficiency of the first plugging structure 10 and the second plugging structure 20.
