All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 to 10, the plugging mechanism of the LED display device of the present embodiment includes a plugging base 10 and a plugging head 20. The plug seat 10 includes a first seat body 11 and a first conductor 12 penetrating the first seat body 11. An external power conducting position 14 is arranged in the first seat body 11, and the external power conducting position 14 is electrically connected with the first conductor 12. The plug 20 includes a second socket body 21 and a second conductor 22 disposed in the second socket body 21.

The plug 20 further comprises a driving structure 25 capable of driving the conductive barrel 222 to move, and the conductive barrel 222 has an on position and an off position. When the conductive tube 222 is at the conducting position, the conductive tube 222 extends out of the second base body 21 to be connected with the first conductor 12 of the other plug-in mechanism of the LED display device in a plugging manner. And the conductive cylinder 222 is in the open position, the conductive cylinder 222 is retracted into the second seat body 21 to be separated from the first conductive body 12.

By applying the technical scheme of the embodiment, the plug mechanism of the LED display device comprises a plug seat 10 and a plug head 20. The socket 10 and the plug 20 may be respectively mounted on two opposite sides of the case 30 of the LED display unit. The plug 20 on one of the two LED display units can be plug-fitted with the plug socket 10 on the other of the two LED display units. The plug seat 10 includes a first seat body 11 and a first conductor 12 penetrating the first seat body 11. An external power conducting position 14 is arranged in the first seat body 11, and the external power conducting position 14 is electrically connected with the first conductor 12. The external power supply 60 is connected to the external power supply conducting position 14, so that the external power supply 60 can supply power to the first electric conductor 12. The plug 20 includes a second socket body 21 and a second conductor 22 disposed in the second socket body 21. The second electrical conductor 22 includes a conductive post 221 and a conductive barrel 222. The conductive post 221 is fixedly connected to the second base body 21, the conductive cylinder 222 is movably sleeved on the conductive post 221, and the conductive cylinder 222 is electrically connected with the conductive post 221. The plug 20 further includes a driving structure 25 capable of driving the conductive tube 222 to move, and when the driving structure 25 drives the conductive tube 222 to move, the conductive tube 222 moves relative to the conductive post 221 and is electrically connected with the conductive post 221.

Thus, the conductive barrel 222 is driven to move by the driving structure 25, so that the conductive barrel 222 can be switched between the on position and the off position. The driving structure 25 can control the electrical connection between one LED display unit in the LED display device and other adjacent LED display units, so that the problem that the LED display unit needs to be detached from the other adjacent LED display units when the LED display unit in the LED display device is disconnected from the test circuit in the related art is avoided. When a test is required for a part of the LED display units in the LED display device, the driving structure 25 of another part of the LED display units in the LED display device is controlled, and the conductive cylinder 222 driving another part of the LED display units in the LED display device is retracted into the second seat body 21 to be separated from the first conductive body 12, so that the circuit connection of the part of the LED display units in the LED display device and the another part of the LED display units in the LED display device can be disconnected. Therefore, the operation of disconnecting another part of the LED display units in the LED display device which do not need to be tested from the test circuit is convenient, and the consumption of electric energy is reduced. Therefore, the technical scheme of the embodiment effectively solves the problem of higher electric energy consumption when testing a part of LED display units in the LED display device in the related technology.

As shown in fig. 10, the plug 20 further includes a conductive elastic member 23 disposed in the conductive barrel 222, and the conductive barrel 222 is electrically connected to the conductive post 221 through the conductive elastic member 23. The conductive elastic member 23 is disposed such that the conductive barrel 222 can maintain electrical connection with the conductive post 221 through the conductive elastic member 23 when the conductive barrel 222 moves on the conductive post 221. Since the conductive elastic member 23 has elasticity, the conductive elastic member 23 can elastically deform, so that the conductive elastic member 23 can better abut between the conductive cylinder 222 and the conductive post 221 under the action of elasticity, and the conductive cylinder 222 and the conductive post 221 can be kept electrically connected through the conductive elastic member 23. The conductive elastic member 23 is disposed in the conductive cylinder 222, and when the conductive cylinder 222 moves on the conductive post 221, the conductive elastic member 23 in the conductive cylinder 222 moves relative to the conductive post 221.

In the present embodiment, the flashlight 222 includes a cylindrical body and a rod body electrically connected to the cylindrical body. The conductive post 221 extends into the barrel portion of the conductive barrel 222, and the rod portion of the conductive barrel 222 is connected with the first conductor 12 in a plugging manner.

As shown in fig. 10, the conductive elastic member 23 includes a conductive sleeve 231, and the conductive sleeve 231 facilitates connection of the conductive elastic member 23 with the conductive barrel 222. The side wall of the conductive sleeve 231 is concavely arranged from the outside to the inside of the conductive sleeve 231, the outer side wall of the conductive sleeve 231 is attached to the inner side wall of the conductive cylinder 222, and the inner side wall of the conductive sleeve 231 is in abutting fit with the outer side wall of the conductive post 221, so that the conductive cylinder 222, the conductive elastic piece 23 and the conductive post 221 are electrically connected. In this way, the inner side wall of the part of the conductive sleeve 231 recessed from the outside to the inside of the conductive sleeve 231 can be abutted against the outer side wall of the conductive post 221, so that when the conductive torch 222 drives the conductive elastic piece 23 to move, the part of the conductive sleeve 231 recessed from the outside to the inside of the conductive sleeve 231 can be kept in electrical connection with the conductive post 221, and the conductive sleeve is simple in structure and convenient to process. In this embodiment, the outer sidewall of the conductive sleeve 231 is connected to the inner sidewall of the conductive sleeve 231.

As shown in fig. 10, a strip-shaped hole 232 is provided on the side wall of the conductive sleeve 231, and the strip-shaped hole 232 penetrates the inner side surface and the outer side surface of the conductive sleeve 231. When the inner side wall of the conductive sleeve 231 is in butt fit with the conductive post 221, the strip-shaped holes 232 can enable the inner side wall of the conductive sleeve 231 to generate larger deformation, so that the inner side wall of the conductive sleeve 231 can be in better butt fit with the conductive post 221, and the conductive barrel 222 is more stable and reliable in electric connection with the conductive post 221 through the conductive elastic piece 23.

As shown in fig. 1 to 10, the plug 20 further includes an insulator 24 movably disposed in the second base body 21, the insulator 24 is fixedly connected to the outside of the conductive cylinder 222, and the driving structure 25 drives the insulator 24 to move so as to drive the conductive cylinder 222 on the insulator 24 to move. The provision of the insulator 24 facilitates the driving connection of the driving structure 25 with the conductive barrel 222 so that the driving structure 25 can more smoothly drive the conductive barrel 222 to move. In addition, the insulator 24 avoids the electrical connection between the driving structure 25 and the conductive cylinder 222, so that the operator can operate the driving structure 25 more safely.

As shown in fig. 1 to 10, the second seat body 21 is provided with a dodging hole 26 through which the insulator 24 and the conductive tube 222 extend, and the dodging hole 26 enables the insulator 24 and the conductive tube 222 to penetrate out of the dodging hole 26 to be connected with the first conductive body 12 in a plugging manner. In addition, when the insulator 24 and the conductive tube 222 extend out of the avoidance hole 26, the avoidance hole 26 can play a role in guiding the insulator 24 and the conductive tube 222, so that the alignment of the conductive tube 222 and the first conductor 12 is more accurate when the conductive tube 222 is inserted into the first conductor 12. The insulator 24 includes an insulating block 241 fixedly connected to the outside of the conductive cylinder 222, and a first insert piece 242 and a second insert piece 243 which are arranged on the end surface of the insulating block 241 at intervals, wherein the first insert piece 242 and the second insert piece 243 are located on two sides of the conductive cylinder 222. This makes the structure of the insulator 24 more compact and easy to process.

The avoiding opening 13 is convenient for inserting the insulator 24 and the conductive cylinder 222, so that the conductive cylinder 222 and the first conductor 12 can be connected in a plugging manner.

Thus, when the rotating shaft 251 rotates, the swing arm 252 is driven to swing by taking the rotating shaft 251 as a swing center, and the second end of the swing arm 252 drives the insulator 24 to move through the hinge shaft 244, so that the conductive cylinder 222 in the insulator 24 can be switched between the on position and the off position. The rotating shaft 251 and the swing arm 252 are simple and reliable in structure, convenient to process, compact in structure and small in occupied space. The swing arm 252 includes a first limiting plate 2521 and a second limiting plate 2522 that are disposed at intervals, so that when the second end of the swing arm 252 drives the insulator 24 to move through the hinge 244, the conductive cylinder 222 in the insulator 24 can receive the force of the first limiting plate 2521 and the second limiting plate 2522, so that the stress of the conductive cylinder 222 in the insulator 24 is more uniform, and the movement of the conductive cylinder 222 is more stable. The rotation shaft 251 is rotationally connected to the swing arm 252, so that the swing arm 252 can be driven to swing when the rotation shaft 251 rotates, and relative rotation between the rotation shaft 251 and the swing arm 252 is avoided. The first stopper 2521 is interposed between the first side of the insulator 24 and the inner sidewall of the second socket body 21, and the second stopper 2522 is interposed between the second side of the insulator 24 and the inner sidewall of the second socket body 21. Thus, the first stopper plate 2521 and the second stopper plate 2522 can swing between the insulator 24 and the second seat body 21.
