[0002] The LED display device includes multiple LED display units and multiple power supply components, with each power supply component corresponding to one of the multiple LED display units. Each power supply component includes a socket, a connector, and conductive wires electrically connected between the connector and the socket.

[0003] LED display devices contain multiple flexible wires used for conduction or signal transmission. When maintaining or testing an LED display device, specific flexible wires need to be plugged in and out. However, due to the large number of flexible wires within an LED display device, it is easy to misoperate when plugging or unplugging specific flexible wires, such as accidentally pulling a wire out of the socket or plug head, or pulling out a wire tangled with other flexible wires along with the other flexible wires, thus affecting the efficiency of LED display device maintenance or testing. Summary of the Invention

[0004] The main objective of this invention is to provide a power supply assembly and an LED display device to solve the problem in the related art where the conductive wires electrically connected between the plug and socket are easily misoperated during maintenance or testing of the LED display device.

[0005] To achieve the above objectives, according to one aspect of the present invention, a power supply assembly for an LED display device is provided, comprising: a socket including a first socket body and a first plug-in portion passing through the first socket body, wherein an external power supply mounting position is provided in the first socket body and the external power supply mounting position is electrically connected to the first plug-in portion; a plug head including a second socket body and a second plug-in portion movably disposed in the second socket body, the second plug-in portion having a connection position extending out of the second socket body and a separation position retracted into the second socket body; a fixed conductive plate electrically connected to the first plug-in portion; and a movable conductive plate movably disposed on the fixed conductive plate and electrically connected to the fixed conductive plate, the movable conductive plate being electrically connected to the second plug-in portion, and the movable conductive plate and the second plug-in portion being movable together.

[0006] Furthermore, the power supply component of the LED display device also includes a conductive spring connected to a fixed conductive plate, and the fixed conductive plate is electrically connected to the movable conductive plate through the conductive spring.

[0007] Furthermore, the conductive spring includes a first segment and a second segment connected at an angle, the first end of the first segment and the first end of the second segment are connected to a fixed conductive plate, and the second end of the first segment and the second end of the second segment abut against a movable conductive plate at an angle.

[0008] Furthermore, both the first end of the first segment and the first end of the second segment are provided with inserts, and the fixed conductive plate is provided with slots for inserting and connecting with the inserts.

[0009] Furthermore, the fixed conductive plate has strip-shaped conductive sheets, and the orthographic projections of the first segment and the second segment onto the surface of the strip-shaped conductive sheets are all located within the strip-shaped conductive sheets.

[0010] Furthermore, the fixed conductive plate includes a first conductive plate base and a first conductive plate body disposed on the first conductive plate base, and the movable conductive plate includes a second conductive plate base and a second conductive plate body disposed on the second conductive plate base. The second conductive plate base is movably disposed on the first conductive plate base, and the second conductive plate body is electrically connected to the first conductive plate body. A first magnetic attractor is disposed on the first conductive plate base, and a second magnetic attractor is disposed on the second conductive plate base that can magnetically engage with the first magnetic attractor. When the first magnetic attractor and the second magnetic attractor are magnetically engaged, the movable conductive plate drives the second plug-in part to be in a separated position. An elastic member is disposed between the first conductive plate base and the second conductive plate base. The elastic member applies a spring force to the second conductive plate base away from the first conductive plate base. When the spring force is greater than the magnetic attraction force between the first magnetic attractor and the second magnetic attractor, the movable conductive plate drives the second plug-in part to be in a connected position.

[0011] Furthermore, a mounting post is provided on the first conductive plate base, and a connection hole is provided on the second conductive plate base. The mounting post extends into the connection hole, and an elastic element is sleeved on the outside of the mounting post. A first magnetic suction element is installed on the end of the mounting post facing the bottom wall of the connection hole, and a second magnetic suction element is provided on the bottom wall of the connection hole.

[0012] Furthermore, a guide structure is provided between the first conductive plate base and the second conductive plate base. The guide structure includes a guide protrusion and a guide groove that guides and cooperates with the guide protrusion. Both the guide protrusion and the guide groove extend along the moving direction of the movable conductive plate. The guide protrusion is provided on one of the second conductive plate base and the first conductive plate base, and the guide groove is provided on the other of the second conductive plate base and the first conductive plate base. A limiting structure is provided between the first conductive plate base and the second conductive plate base. The limiting structure includes a limiting elongated hole and a stop member located in the limiting elongated hole. The free end of the stop member cooperates with the stop of the second conductive plate base. The long axis of the limiting elongated hole extends along the moving direction of the movable conductive plate. The limiting elongated hole is provided on one of the second conductive plate base and the first conductive plate base, and the stop member is provided on the other of the second conductive plate base and the first conductive plate base. When the movable conductive plate moves on the fixed conductive plate, the stop member cooperates with the first end sidewall of the limiting elongated hole to limit the second insertion part to the connected position, and the stop member cooperates with the second end sidewall of the limiting elongated hole to limit the second insertion part to the separated position.

[0013] Furthermore, the plug-in head also includes a drive member rotatably mounted on the second body, which drives the second plug-in part to switch between a connected position and a disconnected position.

[0014] According to another aspect of the present invention, an LED display device is provided, comprising a plurality of LED display units and a plurality of power supply components, wherein the plurality of power supply components are disposed on the plurality of LED display units in a corresponding manner, and the power supply components are the power supply components of the LED display device described above.

[0015] According to the technical solution of this invention, the power supply assembly of an LED display device includes a socket, a plug-in head, a fixed conductive plate, and a movable conductive plate. The socket includes a first base body and a first plug-in portion passing through the first base body. An external power supply mounting position is provided within the first base body, and the external power supply mounting position is electrically connected to the first plug-in portion. The external power supply can be directly installed at the external power supply mounting position within the first base body, enabling the external power supply to power the first plug-in portion, avoiding the need for a conductive wire to electrically connect the external power supply to the first plug-in portion, and also avoiding the problem of accidental operation of the conductive wire. The plug-in head includes a second base body and a second plug-in portion movably disposed within the second base body. The second plug-in portion has a connection position extending out of the second base body and a separation position retracted into the second base body. The fixed conductive plate is electrically connected to the first plug-in portion. The movable conductive plate is movably disposed on the fixed conductive plate and maintains an electrical connection with the fixed conductive plate. The movable conductive plate is electrically connected to the second plug-in portion, and the movable conductive plate and the second plug-in portion can move together. The movable conductive plate and the second plug-in part can move together. When the second plug-in part moves, it can drive the movable conductive plate to move relative to the fixed conductive plate, and the movable conductive plate maintains an electrical connection with the fixed conductive plate. This ensures that when the second plug-in part moves, the first plug-in part and the second plug-in part can also maintain an electrical connection through the fixed conductive plate and the movable conductive plate. The first plug-in part of the plug socket and the second plug-in part of the plug head are electrically connected through the fixed conductive plate and the movable conductive plate. The fixed conductive plate and the movable conductive plate can be distinguished from the flexible wires in the LED display device, avoiding the problem of the electrical connection between the first plug-in part and the second plug-in part being broken due to incorrect identification of the flexible wires. It also avoids the problem of pulling out conductive wires that are tangled with other flexible wires when pulling out other flexible wires, making the electrical connection between the first plug-in part and the second plug-in part more stable and reliable. Therefore, the technical solution of this application effectively solves the problem in the related art that the conductive wires electrically connected between the plug head and the plug socket are easily misoperated when maintaining or testing the LED display device.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0035] like Figures 1 to 4 As shown, the power supply assembly of the LED display device in this embodiment includes a socket 10, a plug-in head 20, a fixed conductive plate 30, and a movable conductive plate 40. The socket 10 includes a first base body 11 and a first plug-in portion 12 passing through the first base body 11. An external power supply mounting position 13 is provided within the first base body 11, and the external power supply mounting position 13 is electrically connected to the first plug-in portion 12. The plug-in head 20 includes a second base body 21 and a second plug-in portion 22 movably disposed within the second base body 21. The second plug-in portion 22 has a connection position extending out of the second base body 21 and a separation position retracted into the second base body 21. The fixed conductive plate 30 is electrically connected to the first plug-in portion 12. The movable conductive plate 40 is movably disposed on the fixed conductive plate 30 and maintains an electrical connection with the fixed conductive plate 30. The movable conductive plate 40 is electrically connected to the second plug-in portion 22, and the movable conductive plate 40 and the second plug-in portion 22 can move together.

[0036] According to the technical solution of this invention, the power supply assembly of the LED display device includes a plug-in socket 10, a plug-in head 20, a fixed conductive plate 30, and a movable conductive plate 40. The plug-in socket 10 includes a first base body 11 and a first plug-in portion 12 passing through the first base body 11. An external power supply mounting position 13 is provided within the first base body 11, and the external power supply mounting position 13 is electrically connected to the first plug-in portion 12. An external power supply 90 can be directly installed on the external power supply mounting position 13 within the first base body 11, so that the external power supply 90 can supply power to the first plug-in portion 12, avoiding the need to use a conductive wire to electrically connect the external power supply 90 to the first plug-in portion 12, and also avoiding the problem of accidental operation of the conductive wire. The fixed conductive plate 30 is electrically connected to the first plug-in portion 12. The movable conductive plate 40 is movably disposed on the fixed conductive plate 30 and maintains an electrical connection with the fixed conductive plate 30. The movable conductive plate 40 is electrically connected to the second plug-in portion 22. Furthermore, the movable conductive plate 40 and the second plug-in part 22 can move together. The movable conductive plate 40 enables the second plug-in part 22 to move. When the second plug-in part 22 moves, it drives the movable conductive plate 40 to move relative to the fixed conductive plate 30. The movable conductive plate 40 and the fixed conductive plate 30 maintain an electrical connection, so that when the second plug-in part 22 moves, the first plug-in part 12 and the second plug-in part 22 can also maintain an electrical connection through the fixed conductive plate 30 and the movable conductive plate 40. The first plug-in portion 12 of the socket 10 and the second plug-in portion 22 of the plug-in head 20 are electrically connected via a fixed conductive plate 30 and a movable conductive plate 40. The fixed conductive plate 30 and the movable conductive plate 40 are designed to distinguish the plug-in portion 12 from the flexible wires within the LED display device, preventing the electrical connection between the first plug-in portion 12 and the second plug-in portion 22 from being broken due to incorrect identification of the flexible wires. This also prevents the accidental removal of conductive wires tangled with other flexible wires when removing them, making the electrical connection between the first plug-in portion 12 and the second plug-in portion 22 more stable and reliable. Therefore, the technical solution of this application effectively solves the problem in related technologies where the conductive wires electrically connected between the plug-in head and the socket are easily misoperated during maintenance or testing of the LED display device.

[0037] In this embodiment, the plug-in socket 10 and the plug-in head 20 are respectively installed on two opposite sides of the housing of the LED display unit. The plug-in head 20 on one of the two LED display units can be plugged into the plug-in socket 10 on the other LED display unit to enable electrical connection between the two LED display units. An external power supply 90 can supply power to the first plug-in portion 12 of the plug-in socket 10 on one LED display unit. The first plug-in portion 12 of the plug-in socket 10 on one LED display unit transmits electrical energy to the second plug-in portion 22 of the plug-in head 20 on one LED display unit through the fixed conductive plate 30 and the movable conductive plate 40. The second plug-in portion 22 of the plug-in head 20 on one LED display unit is electrically connected to the first plug-in portion 12 of the plug-in socket 10 on the adjacent other LED display unit to transfer electrical energy from one LED display unit to the other LED display unit.

[0038] like Figures 4 to 6 As shown, the power supply assembly of the LED display device also includes a conductive spring 50 connected to the fixed conductive plate 30. The fixed conductive plate 30 is electrically connected to the movable conductive plate 40 through the conductive spring 50. Because the conductive spring 50 is elastic, it can undergo elastic deformation, allowing it to abut against the fixed conductive plate 30 and the movable conductive plate 40 under elastic action. This ensures that the fixed conductive plate 30 and the movable conductive plate 40 maintain an electrical connection through the conductive spring 50 while moving relative to each other. The conductive spring 50 makes the electrical connection between the movable conductive plate 40 and the fixed conductive plate 30 more stable and reliable, thus making the electrical connection between the first insertion / extraction portion 12 of the socket 10 and the second insertion / extraction portion 22 of the plug-in head 20 more stable and reliable.

[0039] like Figures 4 to 6 As shown, the conductive spring 50 includes a first segment 51 and a second segment 52 connected at an angle. The first end of the first segment 51 and the first end of the second segment 52 are connected to the fixed conductive plate 30, and the angled connection between the second ends of the first segment 51 and the second ends of the second segment 52 abuts against the movable conductive plate 40. Because the first segment 51 and the second segment 52 are connected at an angle, the thickness of the conductive spring 50 is increased, and the second ends of the first segment 51 and the second ends of the second segment 52 can generate a larger amount of deformation when they abut against the movable conductive plate 40. When the movable conductive plate moves relative to the fixed conductive plate, the larger amount of deformation helps the conductive spring 50 fixed to the fixed conductive plate 30 maintain its electrical connection with the movable conductive plate, and makes the movement of the movable conductive plate smoother.

[0040] In this embodiment, specifically, there are two first segments 51 and two second segments 52, and the two first segments 51 and the two second segments 52 are connected alternately at an angle along the moving direction of the moving conductive plate 40.

[0041] In other embodiments, the conductive spring can be connected to the fixed conductive plate and abut against the fixed conductive plate and the movable conductive plate, so as to maintain the electrical connection between the fixed conductive plate and the movable conductive plate. For example, the conductive spring can also be an arc-shaped conductive sheet, with both ends of the arc-shaped conductive sheet fixed to the fixed conductive plate and the arc-shaped protrusion of the arc-shaped conductive sheet abutting against the movable conductive plate.

[0042] like Figures 4 to 6 As shown, both the first end of the first segment 51 and the first end of the second segment 52 are provided with inserts 53, and the fixed conductive plate 30 is provided with slots 33 for inserting and connecting with the inserts 53. The inserts 53 and slots 33 facilitate the connection between the first ends of the first segment 51 and the first ends of the second segment 52 and the fixed conductive plate 30, making the connection between the first ends of the first segment 51 and the first ends of the second segment 52 and the fixed conductive plate 30 more stable and reliable, and convenient for assembly. The structure of the inserts 53 and slots 33 is simple and reliable, and easy to manufacture.

[0043] like Figures 4 to 6 As shown, the fixed conductive plate 30 has a strip-shaped conductive sheet 34. The orthographic projections of the first segment 51 and the second segment 52 onto the surface of the strip-shaped conductive sheet 34 are all located within the strip-shaped conductive sheet 34. This avoids interference between the first segment 51 and the second segment 52 and the portion of the fixed conductive plate 30 where the strip-shaped conductive sheet 34 is not provided, making the electrical connection between the conductive spring 50 and the fixed conductive plate 30 more reliable and stable. When the processing precision of the fixed conductive plate 30 is low, the portion of the fixed conductive plate 30 without the strip-shaped conductive sheet 34 protrudes beyond the portion with the strip-shaped conductive sheet 34. The orthographic projections of the first segment 51 and the second segment 52 toward the strip-shaped conductive sheet 34 are located within the strip-shaped conductive sheet 34, preventing contact between the conductive spring 50 and the portion of the fixed conductive plate 30 protruding from the portion with the strip-shaped conductive sheet 34.

[0044] like Figures 1 to 6As shown, the fixed conductive plate 30 includes a first conductive plate base 31 and a first conductive plate body 32 disposed on the first conductive plate base 31. The first conductive plate base 31 facilitates the placement of the first conductive plate body 32. The movable conductive plate 40 includes a second conductive plate base 41 and a second conductive plate body 42 disposed on the second conductive plate base 41. The second conductive plate base 41 facilitates the placement of the second conductive plate body 42. The second conductive plate base 41 is movably disposed on the first conductive plate base 31, and the second conductive plate body 42 remains electrically connected to the first conductive plate body 32. This configuration allows the second insertion / removal part 22 to switch between a connected position and a disconnected position via the movable second conductive plate base 41, while ensuring that the relatively fixed position of the first conductive plate base 31 facilitates electrical connection with other components. A first magnetic attractor is provided on the first conductive plate base 31, and a second magnetic attractor 43 is provided on the second conductive plate base 41, which can magnetically engage with the first magnetic attractor. When the first magnetic attractor and the second magnetic attractor 43 are magnetically engaged, the moving conductive plate 40 drives the second plug-in portion 22 to the separated position. Thus, when the second plug-in portion 22 of the plug-in head 20 on one LED display unit separates from the first plug-in portion 12 of the plug-in base 10 on another adjacent LED display unit, the magnetic engagement of the first magnetic attractor and the second magnetic attractor 43 allows the second plug-in portion 22 to smoothly retract into the second base body 21, enabling the second plug-in portion 22 to switch to the separated position. Furthermore, the magnetic engagement of the first magnetic attractor and the second magnetic attractor 43 keeps the second plug-in portion 22 in the separated position.

[0045] In this embodiment, the first conductive plate body 32 of the fixed conductive plate 30 and the second conductive plate body 42 of the movable conductive plate 40 are electrically connected through a conductive spring piece 50.

[0046] In an embodiment not shown in the figure, the fixed conductive plate may consist only of the first conductive plate body, and the movable conductive plate may consist only of the second conductive plate body. In this case, the plug-in socket and the plug-in head are respectively installed on two adjacent sides of the housing of the LED display unit.

[0047] like Figures 4 to 6As shown, an elastic element 60 is provided between the first conductive plate base 31 and the second conductive plate base 41. The elastic element 60 applies a spring force to the second conductive plate base 41 away from the first conductive plate base 31. When the spring force is greater than the magnetic attraction force between the first magnetic attractor and the second magnetic attractor 43, the conductive plate 40 is moved to bring the second plug-in part 22 into the connection position. Thus, when the second plug-in part 22 of the plug-in head 20 on one LED display unit needs to be electrically connected to the first plug-in part 12 of the plug-in base 10 on another adjacent LED display unit, the second plug-in part 22 is driven to move, so that the second magnetic attractor 43 on the second conductive plate base 41 moves away from the first magnetic attractor on the first conductive plate base 31, and the magnetic attraction between the first magnetic attractor and the second magnetic attractor 43 gradually disappears. When the spring force is greater than the magnetic attraction force between the first magnetic attractor and the second magnetic attractor 43, the second plug-in part 22 moves away from the first conductive plate base 31 under the action of the elastic element 60, so that the second plug-in part 22 extends out of the second base body 21 and switches to the connection position. Furthermore, the elastic element 60 facilitates the second insertion / removal part 22 to remain in the connected position.

[0048] In this embodiment, the elastic element 60 is a compression spring. When the second insertion / removal part 22 is in the separated position, the first magnetic attractor and the second magnetic attractor 43 are magnetically attracted to each other, and the compression spring is compressed. When the second insertion / removal part 22 switches from the separated position to the connected position, the first magnetic attractor and the second magnetic attractor 43 separate, and the compression spring applies a spring force to the second conductive plate seat 41 in a direction away from the first conductive plate seat 31.

[0049] like Figures 4 to 6 As shown, a mounting post 35 is provided on the first conductive plate base 31, and a connecting hole is provided on the second conductive plate base 41. The mounting post 35 extends into the connecting hole, and the elastic member 60 is sleeved on the outside of the mounting post 35. The mounting post 35 facilitates the placement of the elastic member 60 and the first magnetic suction member, providing guidance for the compression and elongation of the elastic member 60, and also guiding the movement of the second conductive plate base 41 on the first conductive plate base 31 in conjunction with the connecting hole, thus making the movement of the second conductive plate base 41 on the first conductive plate base 31 more stable. The first magnetic suction member is installed on the end of the mounting post 35 facing the bottom wall of the connecting hole, and the second magnetic suction member 43 is disposed on the bottom wall of the connecting hole. This makes the placement of the first magnetic suction member and the second magnetic suction member 43 more convenient and quick, and easier to process.

[0050] like Figures 4 to 6As shown, a guide structure 70 is provided between the first conductive plate seat 31 and the second conductive plate seat 41. The guide structure 70 includes a guide protrusion 71 and a guide groove 72 that guides and cooperates with the guide protrusion 71. Both the guide protrusion 71 and the guide groove 72 extend along the moving direction of the movable conductive plate 40. The guide protrusion 71 is disposed on the second conductive plate seat 41, and the guide groove 72 is disposed on the first conductive plate seat 31. The arrangement of the guide protrusion 71 and the guide groove 72 allows the second conductive plate seat 41 to move along the guiding direction of the guide structure 70 on the first conductive plate seat 31. The guiding direction of the guide structure 70 is the moving direction of the movable conductive plate 40, making the movement of the movable conductive plate 40 on the second conductive plate seat 41 smoother. The structure of the guide protrusion 71 and the guide groove 72 is simple and reliable, and easy to process.

[0051] In an embodiment not shown in the figure, a guide protrusion is disposed on the first conductive plate base, and a guide groove is disposed on the second conductive plate base.

[0052] like Figure 2 As shown, a limiting structure 80 is provided between the first conductive plate base 31 and the second conductive plate base 41. The limiting structure 80 includes a limiting elongated hole 81 and a stop member 82 located within the limiting elongated hole 81. The free end of the stop member 82 engages with the second conductive plate base 41, and the long axis of the limiting elongated hole 81 extends along the moving direction of the movable conductive plate 40. The limiting elongated hole 81 is provided on the second conductive plate base 41, and the stop member 82 is provided on the first conductive plate base 31. When the movable conductive plate 40 moves on the fixed conductive plate 30, the stop member 82 engages with the first end sidewall of the limiting elongated hole 81 to keep the second insertion / extraction part 22 in a connected position, and the stop member 82 engages with the second end sidewall of the limiting elongated hole 81 to keep the second insertion / extraction part 22 in a separated position. The limiting structure 80 can restrict the movement range of the second conductive plate base 41 on the first conductive plate base 31, so that the second insertion / extraction part 22 connected to the movable conductive plate 40 can switch between the connected position and the separated position. Furthermore, the long axis of the limiting elongated hole 81 extends along the moving direction of the movable conductive plate 40, which can further guide the movement of the second conductive plate seat 41 on the first conductive plate seat 31. The limiting elongated hole 81 and the stop member 82 have a simple and reliable structure and are easy to manufacture. In this embodiment, the stop member 82 is a screw provided on the first conductive plate seat 31, with the screw head located inside the limiting elongated hole 81.

[0053] In an embodiment not shown in the figure, a limiting elongated hole is provided on the first conductive plate base, and a stop member is provided on the second conductive plate base.

[0054] like Figures 4 to 6As shown, the plug-in head 20 also includes a drive member 23 rotatably mounted on the second base body 21. The drive member 23 facilitates the operator's driving of the second plug-in part 22. The drive member 23 drives the second plug-in part 22 to switch between the connected position and the disconnected position, making operation simpler and improving work efficiency.

[0055] In this embodiment, the plug-in head 20 also includes an insulator movably disposed within the second base body 21. The insulator is fixedly connected to the outside of the second plug-in portion 22, and the driving member 23 drives the insulator to move, thereby moving the second plug-in portion 22 on the insulator. The insulator facilitates the driving connection between the driving member 23 and the second plug-in portion 22, allowing the driving member 23 to drive the second plug-in portion 22 to move more smoothly. Furthermore, the insulator prevents electrical connection between the driving member 23 and the second plug-in portion 22, making it safer for the operator to operate the driving member 23.

[0056] In this embodiment, the second base body 21 is provided with mounting holes for the insulator and the second plug-in portion 22 to extend out. The mounting holes allow the insulator and the second plug-in portion 22 to pass through and connect with the first conductor. Furthermore, when the insulator and the second plug-in portion 22 extend out of the mounting holes, the mounting holes act as guides, ensuring more accurate alignment when the second plug-in portion 22 is inserted into the first conductor. The insulator includes an insulating block fixedly connected to the outside of the second plug-in portion 22 and a first insert 53 and a second insert 53 spaced apart on the end face of the insulating block. The first insert 53 and the second insert 53 are located on both sides of the second plug-in portion 22. This makes the insulator structure more compact and easier to manufacture. The first base body 11 is provided with a clearance opening for the insertion of the insulator and the second plug-in portion 22, with the first conductor located within the clearance opening. The clearance opening facilitates the insertion of the insulator and the second plug-in portion 22, allowing the second plug-in portion 22 to connect with the first conductor.

[0057] In this embodiment, a guide ridge is provided at the clearance opening of the first body 11, and a guide groove 72 that mates with the guide ridge is provided on the side of the first insert 53 and the second insert 53 opposite to the second insertion part 22. Both the guide ridge and the guide groove 72 extend along the moving direction of the second insertion part 22.

[0058] In this embodiment, the driving component 23 includes a rotating shaft 231 and a swing arm 232. The rotating shaft 231 is rotatably mounted on the second base body 21, allowing the rotating shaft 231 to rotate relative to the second base body 21. The first end of the swing arm 232 is connected to the rotating shaft 231. A hinge pin 233 is provided on the outer wall of the insulator. The second end of the swing arm 232 is sleeved on the hinge pin 233. The rotating shaft 231 rotates to drive the insulator to move via the swing arm 232, thereby switching the second insertion / extraction part 22 between a connected position and a disconnected position. Thus, when the rotating shaft 231 rotates, it drives the swing arm 232 to swing around the rotating shaft 231 as the swing center. The second end of the swing arm 232 drives the insulator to move via the hinge pin 233, allowing the second insertion / extraction part 22 inside the insulator to switch between a connected position and a disconnected position. The structure of the rotating shaft 231 and the swing arm 232 is simple and reliable, easy to manufacture, and compact, occupying little space. The swing arm 232 includes a first limiting plate and a second limiting plate spaced apart, so that when the second end of the swing arm 232 moves the insulator via the hinge pin 233, the second insertion / extraction portion 22 inside the insulator can be subjected to the force of the first and second limiting plates, making the force on the second insertion / extraction portion 22 inside the insulator more uniform and the movement of the second insertion / extraction portion 22 more stable. A rotating shaft 231 is anti-rotationally connected to the swing arm 232, so that when the rotating shaft 231 rotates, it can drive the swing arm 232 to swing, avoiding relative rotation between the rotating shaft 231 and the swing arm 232. The first limiting plate is clamped between the first side of the insulator and the inner wall of the second base body 21, and the second limiting plate is clamped between the second side of the insulator and the inner wall of the second base body 21. Thus, the first and second limiting plates can swing between the insulator and the second base body 21.

[0059] In this embodiment, the swing arm 232 is provided with a non-rotational hole that engages with the rotating shaft 231. The non-rotational hole facilitates the non-rotational connection between the swing arm 232 and the rotating shaft 231. The rotating shaft 231 is a square prism, and the non-rotational hole is a square hole. The second base body 21 is provided with a circular hole through which the rotating shaft 231 passes. The circular hole facilitates the mounting of the rotating shaft 231 on the second base body 21 and allows the rotating shaft 231 to rotate relative to the second base body 21. The portion of the rotating shaft 231 extending through the circular hole is the operating end, allowing the operator to drive the rotating shaft 231 via the operating end to switch the second insertion / removal part 22 between the connected and disconnected positions. The operating end is provided with a hexagonal countersunk hole, allowing the operator to use an Allen wrench inserted into the hexagonal countersunk hole to drive the rotating shaft 231 to rotate.

[0060] In this embodiment, the second body 21 is provided with a groove 234 that slides with the hinge shaft 233, so that when the insulator moves, the hinge shaft 233 on the insulator can move within the groove 234 on the inner body of the second body, limiting the range and direction of movement of the insulator, thus guiding the movement of the insulator and allowing the second insertion part 22 to move along the extension direction of the groove 234. The second end of the swing arm 232 is provided with a clearance elongated hole 235 for the hinge shaft 233 to pass through, and the long axis of the clearance elongated hole 235 extends from the second end of the swing arm 232 to the first end of the swing arm 232. The clearance elongated hole 235 can avoid the movement of the hinge shaft 233. When the second end of the swing arm 232 swings, the hinge shaft 233 abuts against the wall of the clearance elongated hole 235 on the second end of the swing arm 232 to drive the insulator to move, so that the insulator can drive the second insertion part 22 to move along the extension direction of the groove 234.

[0061] In this embodiment, the second housing 21 includes a detachable first housing and a second housing. The first housing is disposed on the side of the LED display unit, and the second housing is disposed on the side of the first housing opposite to the side of the LED display unit. A receiving cavity is formed within the first and second housings, and the driving member 23 and the insulator are both disposed within the receiving cavity. A circular hole and a clearance elongated hole 235 are provided on both the first and second housings to facilitate the assembly of the second housing 21 with the driving member 23 and the insulator. A limiting protrusion located within the receiving cavity is provided on the bottom surface of the first housing. The two ends of the limiting protrusion are located between the first and second limiting plates to limit the distance between the first and second limiting plates, thereby limiting the movement of the first and second limiting plates on the rotating shaft 231 during swinging. The first housing is disposed on the side of the LED display unit via a connecting plate.

[0062] This application also provides an LED display device. For example... Figure 1 As shown, the LED display device includes multiple LED display units and multiple power supply components. The power supply components are correspondingly disposed on each of the multiple LED display units. These power supply components are those of the aforementioned LED display device. Because the power supply component of the aforementioned LED display device can solve the problem in related technologies where the conductive wires electrically connected between the plug and socket are easily misoperated during maintenance or testing of the LED display device, the LED display device having this power supply component can solve the same technical problem.

[0063] In this embodiment, the LED display device further includes a switching power supply, a busbar, and a conductive plate. The first conductive plate 32 is electrically connected to the switching power supply via the busbar. The switching power supply is electrically connected to the LED display unit via the conductive plate. The switching power supply can convert the AC power transmitted by the first conductive plate 32 into DC power and transmit it to the conductive plate, which then transmits the DC power to the LED display unit.
