[0018] According to another aspect of the present invention, an LED display device is provided, including a first display unit, a second display unit, a plug-in structure, and a plurality of LED display modules. The first display unit and the second display unit are arranged side by side. The plug-in structure is the plug-in structure of the LED display device described above. The power socket of the plug-in mechanism is installed on the side adjacent to the first display unit and the second display unit, and the power plug of the plug-in mechanism is installed on the side adjacent to the second display unit and the first display unit.

[0019] According to another aspect of the present invention, an LED display device is provided, comprising a first display unit, a second display unit, a third display unit, and a fourth display unit, and a plug-in mechanism. The first display unit, the second display unit, the third display unit, and the fourth display unit are arranged in an array and distributed sequentially along the circumference. The plug-in mechanism is the aforementioned plug-in mechanism of the LED display device. The power socket of the plug-in mechanism is installed on the side adjacent to the first display unit and the second display unit, and the power plug of the plug-in mechanism is installed on the side adjacent to the second display unit and the first display unit. The signal socket of the plug-in mechanism is installed on the side adjacent to the first display unit and the second display unit; the signal plug of the plug-in mechanism is installed on the side adjacent to the second display unit and the first display unit; and / or, the signal socket of the plug-in mechanism is installed on the side adjacent to the first display unit and the fourth display unit, and the signal plug of the plug-in mechanism is installed on the side adjacent to the fourth display unit and the first display unit.

[0020] According to the technical solution of this invention, the plug-in mechanism of an LED display device includes a power socket and a power plug. The power socket of the plug-in mechanism can be installed on one adjacent side of two adjacent display units, and the power plug can be installed on the other adjacent side of two adjacent display units. The power socket includes a first base and a first conductive element disposed on the first base.

During the assembly of two adjacent display units, each first driving member receives a first driving force opposite to the direction of the first reset force. When the first driving force received by each first driving member is less than the corresponding first reset force, the second conductive member is in the first disconnected position, and the multiple first driving members cannot move or retract into the second socket, preventing the second conductive member from being inserted into the first socket at an angle. When the first driving force received by each first driving member is greater than the corresponding first reset force, the multiple first driving members can move to drive the second conductive member toward the first conductive member, so that the second conductive member moves from the first disconnected position to the first conductive position. In this process, each first reset member applies a first reset force to the corresponding first driving member, and the multiple first driving members simultaneously receive the first driving force that allows them to move, thus simultaneously driving the second conductive member to move. The second conductive member can smoothly pass through the second socket and be inserted into the first socket, preventing the second conductive member from being tilted, so that the second conductive member can smoothly move from the first disconnected position to the first conductive position. Therefore, the technical solution of this application can solve the problem in the related art where the plug is prone to tilting and difficult to insert into the socket. Furthermore, the power cord can be connected by plugging and unplugging the power socket and power plug while assembling two adjacent display units, simplifying the wiring operation, making the power cord connection simple, and making the assembly of two adjacent display units easier, thus improving assembly efficiency.

[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. 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.

[0054] like Figures 1 to 16As shown, the plugging / unplugging mechanism of the LED display device in this embodiment includes a power socket 10 and a power plug 20. The power socket 10 includes a first base 11 and a first conductive member 12 disposed on the first base 11. The power plug 20 includes a second base 21, a second conductive member 22 movably disposed on the second base 21, two first driving members 23, and two first reset members 24. The two first reset members 24 and the two first driving members 23 are all movably disposed on the second base 21. The two first reset members 24 abut against the two first driving members 23 in a one-to-one correspondence, so that each first reset member 24 applies a first reset force to the corresponding first driving member 23. The second conductive member 22 has a first conductive position that extends out of the second base 21 and contacts and conducts with the first conductive member 12, and a first disconnected position that retracts into the second base 21 and separates from the first conductive member 12. In this embodiment, each first driving member 23 can be subjected to a first driving force in the opposite direction to the first reset force. When the first driving force on each first driving member 23 is less than the corresponding first reset force, the second conductive member 22 is located in the first disconnected position. When the first driving force on each first driving member 23 is greater than the corresponding first reset force, the two first driving members 23 can move to drive the second conductive member 22 toward the first conductive member 12, so that the second conductive member 22 moves from the first disconnected position to the first conductive position.

[0055] Using the technical solution of this embodiment, the power plug 20 of the LED display device's plug-in mechanism can be installed on the other side of two adjacent display units. During the assembly of two adjacent display units, each first driving member 23 can be subjected to a first driving force opposite to the direction of the first reset force. When the first driving force on each first driving member 23 is less than the corresponding first reset force, the second conductive member 22 is in the first disconnected position, and the two first driving members 23 cannot move or retract into the second base 21, preventing the second conductive member 22 from being inserted obliquely into the first base 11. When the first driving force on each first driving member 23 is greater than the corresponding first reset force, the two first driving members 23 can move to drive the second conductive member 22 toward the first conductive member 12 so that the second conductive member 22 moves from the first disconnected position to the first conductive position. In this process, each first reset member 24 applies a first reset force to the corresponding first drive member 23. Both first drive members 23 are simultaneously subjected to the first driving force, enabling them to simultaneously drive the second conductive member 22 to move. The second conductive member 22 can smoothly pass through the second base 21 and insert into the first base 11, preventing the second conductive member 22 from tilting, thus allowing it to smoothly move from the first disconnected position to the first connected position. Therefore, the technical solution of this embodiment can solve the problem in related technologies where the plug is prone to tilting and difficult to insert into the socket. Furthermore, while assembling two adjacent display units, the power cord can be connected by plugging and unplugging the power socket 10 and power plug 20, simplifying the wiring operation, making the power cord connection simple, and making the assembly of two adjacent display units easier, thus improving assembly efficiency. The aforementioned two adjacent display units can be... Figure 2 The first display unit 51 and the second display unit 52 in the middle.

[0056] It should be noted that when the first driving force received by each first driving element 23 is less than the corresponding first reset force, the second conductive element 22 is in the first disconnected position, at which time the second conductive element 22 switches from the first conductive position to the first disconnected position. Alternatively, when each first driving element 23 does not receive the first driving force, the second conductive element 22 remains in the first disconnected position.

[0057] In embodiments not shown in the figures, the number of the first driving member and the first reset member may not be limited to two, but may be three or more.

[0058] like Figure 3 , Figure 7 , Figures 10 to 20As shown, each first driving member 23 includes a first driving rod 231 movably passing through the second base 21 and a first rocker plate 232 swayably disposed within the second base 21. One side of the first end of the first rocker plate 232 abuts against the first driving rod 231, and the second end of the first rocker plate 232 is linked with the second conductive member 22. Each first reset member 24 abuts against the other side of the first end of the first rocker plate 232 of the corresponding first driving member 23, and each first reset member 24 is swayably disposed along the axial direction of the first driving rod 231 of the corresponding first driving member 23.

[0059] In this embodiment, the first driving rod 231 and the first rocker 232 work together in a lever-like manner, enabling the first driving member 23 to drive the second conductive member 22 to move with less effort. To make the second conductive member 22 move more smoothly, the other side of the first end of the two first rockers 232 abuts against the two first reset members 24 in a corresponding manner, and the two first rockers 232 are located on both sides of the second conductive member 22.

[0060] like Figure 3 , Figure 7 , Figures 10 to 20 As shown, the second base 21 is provided with a mounting hole, and the first reset member 24 is a first reset rod 241 movably inserted through the mounting hole. The power plug 20 also includes a third elastic member 27 disposed in the mounting hole. The third elastic member 27 applies a spring force toward the first drive rod 231 to the first reset rod 241. Under the action of the spring force of the third elastic member 27, the first end of the first rocker 232 always remains in contact with one end of the first drive rod 231. When the first driving force received by each first drive member 23 is greater than the corresponding first reset force, the first drive rod 231 moves downward and pushes the first end of the first rocker 232 to swing. The first end of the first rocker 232 can push the first reset rod 241 to move within the second base 21. When the first driving force on each first driving member 23 is less than the corresponding first reset force, the first end of the first rocker 232 always remains in contact with one end of the first driving rod 231, the first end of the first rocker 232 does not swing, and the second conductive member 22 can be located in the first disconnected position to avoid misoperation or uneven first driving force causing the second conductive member 22 to protrude out of the second seat 21.

[0061] like Figure 13As shown, in this embodiment, during the process of installing the first rocker 232 into the second seat 21, due to the elastic force applied by the third elastic member 27 towards the first drive rod 231 to the first reset rod 241, and the small space between the first drive rod 231 and the first reset rod 241, it is inconvenient to place the first end of the first rocker 232 between the first drive rod 231 and the first reset rod 241. To facilitate the placement of the first end of the first rocker 232, a stop adjustment member 26 is provided on the portion of the first reset rod 241 that protrudes from the mounting hole. The stop adjustment member 26 engages with the stop surface of the second seat 21 on the side facing away from the first seat 11. The stop adjustment member 26 can stop the first reset rod 241 in a clearance position, avoiding the first end of the first rocker 232. At this time, there is sufficient space between the first drive rod 231 and the first reset rod 241, which facilitates placing the first end of the first rocker 232 within the space. Then, the position of the stop adjustment member 26 on the first reset rod 241 is adjusted so that the first reset rod 241 always applies a first reset force to the other side of the first end of the first rocker 232. Preferably, the portion of the first reset rod 241 that protrudes from the mounting hole is provided with threads, and the stop adjustment member 26 is a nut, which is rotatably fitted onto the thread.

[0062] like Figure 3 and Figure 13 As shown, the first rocker 232 includes a first plate segment 2321, a rotating shaft 2322, and a second plate segment 2323 connected in sequence. The first plate segment 2321 and the second plate segment 2323 form an obtuse angle. The rotating shaft 2322 is rotatably disposed in the second base 21. The first plate segment 2321 abuts against the first drive rod 231, and the second plate segment 2323 is linked with the second conductive element 22.

[0063] like Figure 13 As shown, one end of the first reset rod 241 is provided with abutting inclined surface that abuts against the first plate segment 2321. In this way, the abutting inclined surface of the first reset rod 241 is adapted to the inclination direction of the first plate segment 2321. On the one hand, this facilitates the first reset rod 241 to avoid the first plate segment 2321 at one end; on the other hand, the abutting inclined surface makes full contact with the surface of the first plate segment 2321, improving the stability of the first plate segment 2321 swinging around the pivot 2322.

[0064] In this embodiment, for ease of assembly, a positioning protrusion is provided on the side wall of the first reset rod 241, and a positioning groove that mates with the positioning protrusion is provided inside the second seat 21.

[0065] like Figure 3 and Figure 13As shown, the second seat 21 includes a seat base 211 and a base plate 212 covering the seat base 211. A first arc-shaped recess 213 is provided within the seat base 211, and a second arc-shaped recess 214 is provided on the surface of the base plate 212 facing the first arc-shaped recess 213. A rotating shaft 2322 is sandwiched between the first arc-shaped recess 213 and the second arc-shaped recess 214. In this way, both the first arc-shaped recess 213 and the second arc-shaped recess 214 are in surface-to-surface contact with the side surface of the rotating shaft 2322, preventing the first rocker 232 from wobbling during its swing around the axis of the rotating shaft. This makes the swing of the first rocker 232 more stable, improves the sensitivity of the swing, and thus makes it easier for the second conductive component 22 to be moved by the first rocker 232.

[0066] like Figure 3 , Figure 7 , Figure 13 as well as Figure 14 As shown, each first driving member 23 also includes a first connecting rod 233. In each first driving member 23, the first end of the first connecting rod 233 is hinged to the second end of the first rocker 232, and the second end of the first connecting rod 233 is hinged to the second conductive member 22. Thus, the first connecting rod 233 enables the second plate segment 2323 to be linked with the second conductive member 22. When the first driving force on each first driving member 23 is greater than the corresponding first reset force, the first driving rod 231 moves downward and pushes the first plate segment 2321 to swing around the pivot 2322. This causes the second plate segment 2323 to swing around the pivot 2322 and push the first connecting rod 233 upward to move the second conductive member 22. The second conductive member 22 can then smoothly move from the first disconnected position to the first connected position. Therefore, by linking the first rocker 232 with the first connecting rod 233, the stability and reliability of each first driving member 23 driving the second conductive member 22 can be improved.

[0067] Specifically, the insulating substrate of the second conductive element 22 includes a substrate block and a first protrusion and a second protrusion spaced apart on the lower surface of the substrate block. There are two first rocker plates 232. The second end of one first rocker plate 232 is hinged to the first protrusion through a first connecting rod 233, and the second end of the other first rocker plate 232 is hinged to the second protrusion through another first connecting rod 233.

[0068] like Figure 3 , Figure 7 , Figures 16 to 21As shown, the power socket 10 also includes a switch 16, which can keep the first conductive element 12 in a conductive or disconnected state. When the first conductive element 12 is connected to an external power source and the display unit is being assembled, the switch 16 can be used to disconnect the first conductive element 12, thus de-energizing the assembled display unit and reducing the possibility of safety accidents. This solves the problem in related technologies where safety accidents are easily caused when the power cord is connected to an external power source and the display unit is being assembled. The switch 16 is preferably a rocker switch.

[0069] To facilitate the insertion of the external power plug 62 into the power socket 10, the power socket 10 also includes an external connector electrically connected to the first conductive element 12, which is located inside the first base 11. Thus, the external power plug 62 can be inserted into the external connector to achieve contact and conduction, thereby connecting the first conductive element 12 to an external power source.

[0070] Specifically, the external power plug 62 includes external power line copper pins, and the power socket 10 also includes a power crown spring that engages with the external power line copper pins.

[0071] like Figure 3 , Figure 7 , Figures 16 to 21 As shown, the first conductive element 12 includes an input conductor 121 and an output conductor 122 installed within the first base 11. The input conductor 121 and the output conductor 122 are disconnected. The switch element 16 includes a connecting conductor installed within the first base 11 and an operation key 161 for moving the connecting conductor. When the connecting conductor moves to engage with the input conductor 121 and the output conductor 122, the two conductors are connected. When the connecting conductor moves to separate from the input conductor 121 and the output conductor 122 respectively, the input conductor 121 and the output conductor 122 are disconnected, putting the first conductive element 12 itself in an off state. Furthermore, since the input conductor 121 and the output conductor 122 are directly installed on the first base 11, the components of the power socket 10 are smaller, the overall structure is simpler, thereby reducing production costs and facilitating later maintenance, making it suitable for small-batch production.

[0072] In this embodiment, the second conductive element 22 includes an insulating substrate movably disposed on the second base 21 and a conductive post disposed within the insulating substrate. The conductive post is floating relative to the insulating substrate along the moving direction of the insulating substrate. The first driving element 23 is movable to drive the insulating substrate to move toward the first conductive element 12, so that the conductive post contacts and conducts electricity with the input conductor 121. The first driving element 23 is also movable to drive the insulating substrate to move away from the first conductive element 12, so that the conductive post separates from the input conductor 121.

[0073] In this embodiment, the second base 21 is provided with a first clearance hole to avoid the conductive post, and the second base 21 is provided with a first receiving hole for installing the third elastic member 27. The first receiving hole and the first clearance hole are connected.

[0074] Specifically, the conductive post is installed and oriented with gaps within an insulating substrate, and spring-loaded within the substrate provides elastic restraint. The conductive post is placed inside the insulating substrate, followed by the spring, and then the substrate is sewn together using a riveting method. The conductive post then floats completely within the insulating substrate.

[0075] Specifically, the conductive posts include a neutral post and a live post. The power plug 20 also includes a ground post. The live post and the ground post are parallel to the neutral post. The neutral post, live post, and ground post are all spaced apart on the insulating substrate. The insulating substrate isolates the neutral post, live post, and ground post to prevent short circuits. The input conductor 121 includes a first neutral conductor and a first live conductor. The output conductor 122 includes a second neutral conductor and a second live conductor. The power socket 10 also includes a ground conductor spaced apart from the second neutral conductor. The first driving member 23 moves to drive the insulating substrate toward the first conductive member 12, so that the neutral post contacts and conducts with the first neutral conductor, the live post contacts and conducts with the first live conductor, and the ground post contacts and conducts with the ground conductor.

[0076] It should be noted that the second conductive element 22 also includes a flexible neutral wire, a flexible live wire, and a flexible ground wire that are electrically connected to the neutral wire post, the live wire post, and the ground post, respectively. The flexible neutral wire, the flexible live wire, and the flexible ground wire can all freely stretch and deform, which facilitates the reciprocating movement of the conductive post with the insulating substrate, so that the second conductive element 22 can switch between the first conducting position and the first disconnecting position.

[0077] Furthermore, the first neutral conductor includes a neutral copper needle passing through the first base 11 and a neutral conductor segment electrically connected to the neutral copper needle, with the neutral copper needle and the neutral conductor segment welded together. Similarly, the first live conductor includes a live copper needle and a live conductor segment, and the ground conductor includes a ground copper needle and a ground conductor segment. When the second conductive element 22 is in the first conductive position, the neutral post of the second conductive element 22 makes point-to-point contact with the neutral copper needle of the first conductive element 12, the live post of the second conductive element 22 makes point-to-point contact with the live copper needle of the first conductive element 12, and the ground post of the second conductive element 22 makes point-to-point contact with the ground copper needle of the first conductive element 12.

[0078] like Figures 11 to 15As shown, to prevent the insulating substrate from tilting during movement within the second housing 21, the power plug 20 also includes a guide structure disposed between the second housing 21 and the insulating substrate. The guide structure includes a guide hole extending along the movement direction of the insulating substrate and a guide post that can be inserted into the guide hole. The guide hole is disposed in the second housing 21, and the guide post is disposed in the insulating substrate. Thus, the guide post is fixedly connected to the insulating substrate. During movement within the second housing 21, because the guide post can move within the guide hole along its axis, the movement of the insulating substrate is limited to the axis of the guide hole, allowing the insulating substrate to move smoothly within the second housing 21.

[0079] Of course, in the embodiment not shown in the figure, the guide post is disposed on the second base body and the guide post is disposed on the insulating substrate.

[0080] like Figure 3 , Figure 7 , Figures 16 to 21 As shown, the power socket 10 also includes a first force-applying member 13 spaced apart from the first base 11. The first force-applying member 13 is movably disposed and can push the first drive rod 231 to move, thereby driving the first rocker 232 to swing. The power socket 10 also includes a first mounting base 14 spaced apart from the first base 11 and a second elastic member 15 disposed within the first mounting base 14. The first force-applying member 13 is movably located within the first mounting base 14, and the second elastic member 15 applies a spring force to the first force-applying member 13 toward the first drive rod 231. Thus, under the action of the spring force of the second elastic member 15, the first force-applying member 13 can move along the first mounting base 14. Figure 3 The first drive rod 231 floats in the Y-axis direction. During the process of the second conductive element 22 moving from the first disconnected position to the first connected position, the second elastic element 15 applies a spring force to the first force-applying element 13 towards the first drive rod 231, so that the first force-applying element 13 always presses down on the first drive rod 231, so that the first drive rod 231 is sandwiched between the first rocker 232 and the first force-applying element 13. After the first force-applying element 13 pushes the first drive rod 231 and the first driving force is greater than the corresponding first reset force, the first drive rod 231 quickly pushes the first end of the first rocker 232 to swing around its axis. Furthermore, after the two adjacent display units are disassembled, the first force-applying element 13 can retract into the first mounting base 14 after being hit, avoiding interference caused by the first force-applying element 13 passing through the first mounting base 14.

[0081] like Figure 3 , Figures 13 to 15As shown, the power plug 20 also includes a third elastic member 27 disposed between the second base 21 and the second conductive member 22. The third elastic member 27 applies a spring force to the second conductive member 22 in a direction away from the first base 11. Thus, under the spring force of the third elastic member 27, the second conductive member 22 can move along the direction away from the second base 21. Figure 3 The second conductive element 22 floats along the Y-axis. During the process of the second conductive element 22 moving from the first conductive position to the first disconnected position, the third elastic element 27 applies a spring force to the second conductive element 22 in a direction away from the first base 11, causing the second conductive element 22 to quickly separate from the first conductive element 12. Furthermore, after two adjacent display units are disassembled, the second conductive element 22 can remain in the first disconnected position, preventing the second conductive element 22 from protruding from the second base 21 and causing damage or interference. The aforementioned third elastic element 27 is a spring or an elastic body. When the third elastic element 27 is a spring, it is preferably a compression spring, which is installed above the insulating substrate. Of course, in the embodiment not shown in the figure, the spring is preferably a tension spring, which is installed below the insulating substrate.

[0082] like Figure 3 , Figures 13 to 15 As shown, when the second conductive element 22 is in the first conductive position, the second conductive element 22 and the first conductive element 12 are in point-to-surface contact.

[0083] It should be noted that the point-to-surface contact between the second conductive element 22 and the first conductive element 12 means that the end of the conductive post of the second conductive element 22 facing the input conductor 121 has a first spherical surface, and the end of the input conductor 121 facing the conductive post has a first flat surface or a first concave arc surface. The contact method between the first spherical surface and the first flat surface or the first concave arc surface is point-to-surface contact. During the assembly of two adjacent display units, the conductive post with the first spherical surface smoothly passes through the second base 21 and makes point-to-surface contact with the input conductor 121 with the first flat surface, so that the second conductive element 22 is in the first conductive position. During the disassembly of two adjacent display units, the conductive post with the first spherical surface smoothly retracts into the second base 21 and separates from the input conductor 121 with the first flat surface, so that the second conductive element 22 is in the first disconnected position.

[0084] Specifically, the second base 21 is provided with a first clearance hole to avoid the conductive post. When two adjacent display units are assembled together and the second conductive member 22 moves from the first disconnected position to the first conductive position, a portion of the first spherical surface of the conductive post slides into contact with the wall of the first clearance hole, and the moving direction of the conductive post is quickly adjusted so that the axis of the conductive post is parallel to the axis of the first clearance hole. The conductive post can smoothly pass through the first clearance hole and out of the second base 21 to make point-to-surface contact with the input conductor 121.

[0085] Of course, in embodiments not shown in the figures, the power plug further includes a third elastic member disposed between the second base and the second conductive member, the third elastic member applying a spring force to the second conductive member in a direction away from the first base. Alternatively, when the second conductive member is in the first conductive position, the second conductive member and the first conductive member make point-to-surface contact.

[0086] like Figure 3 , Figures 13 to 15 As shown, the first force-applying component 13 can make point-to-surface contact with the first drive rod 231. It should be noted that the point-to-surface contact between the first force-applying component 13 and the first drive rod 231 means that the end of the first force-applying component 13 facing the first drive rod 231 has a second spherical surface, and the end of the first drive rod 231 facing the first force-applying component 13 has a second flat surface or a second concave arc surface. The contact method between the second spherical surface and the second flat surface or the second concave arc surface is point-to-surface contact. The second spherical surface protrudes from the surface of the first base 11 facing the second base 21. The second base 21 is also provided with a second clearance hole to avoid the first drive rod 231. The side of the display unit facing the surface of the first base 11 is provided with a first clearance concave arc surface to avoid the second spherical surface. The second clearance hole is located in the first clearance concave arc surface. When the second conductive element 22 is in the first disconnected position, one end of the first drive rod 231 with the second plane extends into the first clearance concave arc surface. The second plane is lower than or flush with the side of the display unit facing the first base 11.

[0087] The aforementioned second elastic element 15 is a spring or an elastic body. The first force-applying element 13 is preferably a first force-applying rod. The power socket 10 also includes a first stop ring disposed at the opening of the first mounting base 14, and a second stop ring that cooperates with the first stop ring is disposed on the side wall of the first force-applying rod. The second spherical surface can pass through the center hole of the first stop ring and exit the first mounting base 14. The gap is oriented by the first mounting base 14 and the second stop ring, and the elastic force is limited by the second elastic element 15 at the same time. The second stop ring ensures the downward pressure of the elastic force of the second elastic element 15 and the gap orientation of the tail of the first force-applying rod. The first force-applying rod floats completely within the first mounting base 14.

[0088] During the assembly of two adjacent display units and the movement of the second conductive element 22 from the first disconnected position to the first conductive position, the second spherical surface of the first force-applying element 13 can directly contact and engage with the second planar point surface of the first drive rod 231, or the second spherical surface of the first force-applying element 13 can move on the side of the display unit toward the surface of the first base 11 and smoothly slide into the first relief concave arc surface to contact and engage with the second planar point surface of the first drive rod 231, so that the first drive rod 231 moves downward relative to the first base 11 and presses down the first end of the first rocker 232, so that the first end of the first rocker 232 swings around its axis, and the second end of the first rocker 232 pushes the second conductive element 22 upward relative to the second base 21, so that the second conductive element 22 is in the first conductive position.

[0089] During the disassembly of two adjacent display units and the movement of the second conductive element 22 from the first conductive position to the first disconnected position, a portion of the second spherical surface of the first force-applying element 13 slides on the first recessed arc surface and gradually separates from the second plane of the first drive rod 231. When the second spherical surface of the first force-applying element 13 is impacted, it can quickly retract into the first mounting base 14 to avoid interference with the second base 21 or the side of the display unit, thus improving the smoothness of the disassembly process. After the first end of the first rocker 232 is pushed upward, one end of the first drive rod 231 with the second plane re-extends into the first recessed arc surface. At the same time, the conductive post with the first spherical surface smoothly retracts into the second base 21 and separates from the input conductor 121 with the first plane, so that the second conductive element 22 is in the first disconnected position.

[0090] During the assembly of the two adjacent display units, the second conductive element 22 can move along the second base 21. Figure 3 The first conductive element 22 floats along the Y-axis direction, and the second conductive element 22 can smoothly make point-to-surface contact with the first conductive element 12; the first force-applying element 13 can move along the Y-axis direction within the first mounting base 14. Figure 3 The power plug 20 floats along the Y-axis, and the first force-applying component 13 can smoothly make point-to-surface contact with the first drive rod 231. There is no interference between the power plug 20 and the power socket 10, and the power plug 20 can be quickly inserted into the power socket 10. Similarly, during the disassembly process of the two adjacent display units, the power plug 20 can be quickly separated from the power socket 10. In this way, the power plug 20 and the power socket 10 can be automatically connected, so that the power supply on the two display units can be automatically electrically connected without the need for on-site personnel to manually plug or unplug the power plug 20, which is convenient for on-site personnel. Figure 3 The two display units are assembled or disassembled along the Y-axis.

[0091] like Figure 1 , Figures 4 to 10 as well as Figures 22 to 29 As shown, the plugging and unplugging mechanism further includes a signal socket 30 and a signal plug 40. The signal socket 30 includes a third base 31 and a first signal transmission member 32 disposed on the third base 31. The signal plug 40 includes a fourth base 41, a second signal transmission member 42 disposed on the fourth base 41, and two second driving members 43 and two second reset members 44 movably disposed on the fourth base 41. The two second reset members 44 and the two second driving members 43 are movably disposed on the second base 21. The two second reset members 44 and the two second driving members 43 abut against each other in a one-to-one correspondence, so that each second reset member 44 applies a second reset force to the corresponding second driving member 43. The second signal transmission member 42 has a second conducting position that extends out of the fourth base 41 and contacts and connects with the first signal transmission member 32, and a second disengaged position that retracts into the fourth base 41 and separates from the first signal transmission member 32. In this embodiment, each second driving member 43 can be subjected to a second driving force opposite to the direction of the second reset force. When the second driving force on each second driving member 43 is less than the second reset force, the second signal transmission member 42 is located in the second disconnected position. When the second driving force on each second driving member 43 is greater than the second reset force, the two second driving members 43 can move to drive the second signal transmission member 42 toward the first signal transmission member 32, so that the second signal transmission member 42 moves from the second disconnected position to the second connected position.

[0092] In this embodiment, the signal plug 40 of the LED display device's plug-in mechanism can be installed on the other side of two adjacent display units. During the assembly of two adjacent display units, each second driving member 43 can be subjected to a second driving force opposite to the direction of the second reset force. When the second driving force on each second driving member 43 is less than the corresponding second reset force, the second signal transmission member 42 is in the second disconnected position, and the two second driving members 43 cannot move or retract into the fourth seat 41, preventing the second signal transmission member 42 from obliquely protruding from the fourth seat 41. When the second driving force on each second driving member 43 is greater than the corresponding second reset force, the two second driving members 43 can move to drive the second signal transmission member 42 toward the first signal transmission member 32 so that the second signal transmission member 42 moves from the second disconnected position to the second connected position. During this process, each second reset member 44 applies a second reset force to the corresponding second drive member 43. Both second drive members 43 are simultaneously subjected to a movable second drive force, enabling them to simultaneously drive the second signal transmission member 42 to move. The second signal transmission member 42 can smoothly pass through the fourth base 41, preventing it from tilting, thus allowing it to smoothly move from the second disconnected position to the second connected position. Furthermore, while assembling adjacent display units, the adjacent display units are powered on by plugging in the power socket 10 and power plug 20, and signal transmission is achieved by plugging in the signal socket 30 and signal plug 40. This simplifies wiring operations, making the connection of power and signal lines simpler, and simplifying the assembly of adjacent display units, thus improving assembly efficiency. The aforementioned adjacent display units can be... Figure 4 The first display unit 51 and the fourth display unit 54 in the middle.

[0093] It should be noted that when the second driving force received by the second driving member 43 is less than the second reset force, the second signal transmission member 42 is in the second disconnected position, at which time the second signal transmission member 42 switches from the second on position to the second disconnected position. Alternatively, when each of the second driving members 43 does not receive the second driving force, the second signal transmission member 42 remains in the first disconnected position.

[0094] In embodiments not shown in the figure, the number of the second driving member and the second reset member may not be limited to two, but may be three or more.

[0095] like Figure 5 , Figure 7 , Figures 22 to 29As shown, each second driving member 43 includes a second driving rod 431 movably passing through the fourth seat 41 and a second rocker plate 432 swayably disposed within the fourth seat 41. One side of the first end of the second rocker plate 432 abuts against the second driving rod 431, and the second end of the second rocker plate 432 is linked with the second signal transmission member 42. Each second reset member 44 abuts against the other side of the first end of the second rocker plate 432 of the corresponding second driving member 43, and each second reset member 44 is swayably disposed along the axial direction of the second driving rod 431 of the corresponding second driving member 43.

[0096] In this embodiment, the second drive rod 431 and the second rocker 432 work together in a lever-like manner, enabling the second drive member 43 to drive the second signal transmission member 42 to move with less effort. To ensure the second signal transmission member 42 moves more smoothly, the other side of the first end of each of the two second rocker plates 432 abuts against each of the two second reset members 44, with the two second rocker plates 432 located on opposite sides of the second signal transmission member 42.

[0097] like Figure 5 , Figure 7 , Figures 22 to 29 As shown, the fourth seat 41 is provided with an assembly hole, and the second reset member 44 is a second reset rod movably inserted through the assembly hole. The signal plug 40 also includes a sixth elastic member disposed in the assembly hole. The sixth elastic member applies a spring force toward the second drive rod 431 to the second reset rod. Under the action of the spring force of the sixth elastic member, the first end of the second rocker 432 always remains in contact with one end of the second drive rod 431. When the second driving force on each second drive member 43 is greater than the corresponding second reset force, the second drive rod 431 moves downward and pushes the first end of the second rocker 432 to swing, and the first end of the second rocker 432 can push the second reset rod to move within the fourth seat 41. When the second driving force on each second driving member 43 is less than the corresponding second reset force, the first end of the second rocker 432 always remains in contact with one end of the second driving rod 431, the first end of the second rocker 432 does not swing, and the second conductive member 22 can be located in the first disconnected position, avoiding misoperation or uneven second driving force causing the second conductive member 22 to protrude out of the fourth seat 41.

[0098] like Figure 5 , Figure 9 , Figures 24 to 27As shown, each second driving member 43 also includes a second connecting rod 433. In each second driving member 43, the first end of the second connecting rod 433 is hinged to the second end of the second rocker 432, and the second end of the second connecting rod 433 is hinged to the second signal transmission member 42. Thus, the second connecting rod 433 enables the second end of the second rocker 432 to be linked with the second signal transmission member 42. When the second driving force on each second driving member 43 is greater than the second reset force, the second driving member 43 moves to the left and pushes the first end of the second rocker 432 to swing around the swing center of the second rocker 432. This, in turn, causes the second end of the second rocker 432 to swing around the swing center of the second rocker 432 and pushes the second connecting rod 433 to the right, moving the second signal transmission member 42. The second signal transmission member 42 can then smoothly move from the second disconnected position to the second connected position. Therefore, by linking the second rocker 432 with the second connecting rod 433, the stability and reliability of each second driving member 43 driving the second signal transmission member 42 can be improved.

[0099] like Figure 5 , Figure 9 , Figures 24 to 27 As shown, the first signal transmission component 32 includes a first signal PCB board, the surface of which facing the second signal transmission component 42 is immersion gold. The second signal transmission component 42 includes an insulating body movably disposed in the fourth base 41 and a signal pin disposed within the insulating body. The signal pin is floating relative to the insulating body along the moving direction of the insulating body. The second driving component 43 is movable to drive the insulating body to move toward the first signal transmission component 32, so that the signal pin contacts and conducts electricity with the first signal transmission component 32. The second driving component 43 is also movable to drive the insulating body to move away from the first signal transmission component 32, so that the signal pin separates from the first signal transmission component 32. The fourth base 41 includes a housing and a cover plate covering the opening of the housing, with part of the second signal transmission component 42 and part of the second driving component 43 located inside the housing. The signal pin is disposed within the insulating body by a signal spring.

[0100] In this embodiment, the signal plug 40 further includes a flexible circuit plug passing through the fourth housing 41, and the second signal transmission component 42 further includes a second signal PCB board. The second signal PCB board is disposed on the side of the insulating body opposite to the first signal transmission component 32. The signal pin is electrically connected to the second signal PCB board. A PCB board socket is provided on the side of the second signal PCB board opposite to the insulating body. The flexible circuit plug and the PCB board socket are mated and engaged. The flexible circuit plug can be electrically connected to the signal pin through the second signal PCB board. Because the flexible circuit plug can extend and deform, each second driving component 43 can be driven to move within the fourth housing 41, thereby allowing the signal pin to move with the insulating body.

[0101] like Figure 5 , Figure 9 and Figure 24 As shown, the signal socket 30 also includes a second force-applying member 33 spaced apart from the third base 31. The second force-applying member 33 is movably disposed and can push the second drive rod 431 to move, thereby driving the second rocker 432 to swing. The signal socket 30 also includes a second mounting base 34 spaced apart from the first base 11 and a fourth elastic member 35 disposed within the second mounting base 34. The second force-applying member 33 is movably located within the second mounting base 34, and the fourth elastic member 35 applies a spring force toward the second drive rod 431 to the second force-applying member 33. Thus, under the spring force of the fourth elastic member 35, the second force-applying member 33 can move along the second mounting base 34. Figure 5 The second signal transmission element 42 floats in the X-axis direction. During the process of the second signal transmission element 42 moving from the second disconnected position to the second connected position, the fourth elastic element 35 applies a spring force to the second force-applying element 33 toward the second drive rod 431, so that the second force-applying element 33 always presses down on the second drive rod 431, so that the second drive rod 431 is clamped between the second rocker plate 432 and the second force-applying element 33. After the second force-applying element 33 pushes the second drive rod 431, the second drive rod 431 quickly pushes the first end of the second rocker plate 432 to swing around its swing axis. Furthermore, after two adjacent display units are disassembled, the second force-applying element 33 can retract into the second mounting base 34 after being hit, avoiding interference caused by the second force-applying element 33 passing through the second mounting base 34.

[0102] The aforementioned fourth elastic element 35 is a spring or an elastic body. The second force-applying element 33 is preferably a second force-applying rod. The signal socket 30 also includes a third stop ring disposed at the opening of the second mounting base 34, and a fourth stop ring is disposed on the side wall of the second force-applying rod to stop and cooperate with the third stop ring. The fourth spherical surface can pass through the center hole of the third stop ring and exit the second mounting base 34.

[0103] like Figure 5 , Figure 9 , Figure 24 as well as Figure 26 As shown, the signal plug 40 also includes a fifth elastic member 45 disposed between the fourth housing 41 and the second signal transmission member 42. The fifth elastic member 45 applies a spring force to the second signal transmission member 42 in a direction away from the third housing 31. Thus, under the action of the spring force of the fifth elastic member 45, the second signal transmission member 42 can move along the direction of the third housing 31 within the fourth housing 41. Figure 5The second signal transmitter 42 floats in the X-axis direction. During the process of the second signal transmitter 42 moving from the second conducting position to the second disconnecting position, the fifth elastic element 45 applies a spring force to the second signal transmitter 42 in the direction away from the third seat 31, so that the second signal transmitter 42 is quickly separated from the first signal transmitter 32. Furthermore, after the two adjacent display units are disassembled, the second signal transmitter 42 can remain in the second disconnecting position, preventing the second signal transmitter 42 from passing through the fourth seat 41 and being damaged or causing interference. The aforementioned fifth elastic element 45 is a spring or an elastic body. When the fifth elastic element 45 is a spring, the spring can preferably be a compression spring. Figure 26 The compression spring is mounted above the insulating body (see below). Of course, in the embodiment not shown in the figure, the spring can preferably be a tension spring, in which case the tension spring is mounted below the insulating body.

[0104] In this embodiment, the fourth seat 41 is provided with a third clearance hole for the clearance signal pin, and the fourth seat 41 is provided with a second receiving hole for mounting the fifth elastic member 45. A guide structure is provided between the fourth seat 41 and the insulating body, and this guide structure is the same as the guide structure between the second seat 21 and the insulating substrate.

[0105] like Figure 5 , Figure 9 , Figure 24 as well as Figure 26 As shown, when the second signal transmission element 42 is in the second conducting position, the second signal transmission element 42 and the first signal transmission element 32 are in point-to-surface contact.

[0106] It should be noted that the point-to-surface contact engagement between the second signal transmission component 42 and the first signal transmission component 32 means that the end of the signal pin of the second signal transmission component 42 facing the first signal PCB board has a third spherical surface, and the gold-plated surface of the first signal PCB board faces the end of the signal pin. The contact method between the third spherical surface and the gold-plated surface is point-to-surface contact. During the assembly of two adjacent display units, the signal pin with the third spherical surface smoothly passes through the fourth housing 41 and engages with the gold-plated surface of the first signal PCB board, so that the second signal transmission component 42 is in the second conducting position. During the disassembly of two adjacent display units, the signal pin with the third spherical surface smoothly retracts into the fourth housing 41 and separates from the gold-plated surface of the first signal PCB board, so that the second signal transmission component 42 is in the second disconnected position.

[0107] Specifically, the fourth housing 41 is provided with a third clearance hole for the signal pin. When two adjacent display units are assembled together and the second signal transmission component 42 moves from the second disconnected position to the second connected position, a portion of the third spherical surface of the signal pin slides into contact with the wall of the third clearance hole, and the moving direction of the signal pin is quickly adjusted so that the axis of the signal pin is parallel to the axis of the third clearance hole. The signal pin can smoothly pass through the third clearance hole and out of the fourth housing 41 to make point-to-surface contact with the first signal PCB board.

[0108] Of course, in embodiments not shown in the figures, the signal socket further includes a second mounting base spaced apart from the first base and a fourth elastic member disposed within the second mounting base. The second force-applying member is movably located within the second mounting base, and the fourth elastic member applies a spring force toward the second drive rod to the second force-applying member, enabling the second force-applying member to make point-to-surface contact with the second drive rod. The signal plug further includes a fifth elastic member disposed between the fourth base and the second signal transmission member, and the fifth elastic member applies a spring force toward the second signal transmission member in a direction away from the third base. Alternatively, when the second signal transmission member is in the second conducting position, the second signal transmission member makes point-to-surface contact with the first signal transmission member.

[0109] like Figure 5 , Figure 9 , Figure 24 as well as Figure 26 As shown, the second force-applying component 33 can make point-to-surface contact with the second drive rod 431.

[0110] It should be noted that the second force-applying component 33 being able to make point-to-surface contact with the second drive rod 431 means that the end of the second force-applying component 33 facing the second drive rod 431 has a fourth spherical surface, and the end of the second drive rod 431 facing the second force-applying component 33 has a third plane or a third concave arc surface. The contact method between the fourth spherical surface and the third plane or the third concave arc surface is point-to-surface contact. The fourth spherical surface protrudes from the surface of the first signal PCB board facing the fourth base 41. The fourth base 41 is also provided with a fourth clearance hole to avoid the second drive rod 431. The side of the display unit facing the surface of the first signal PCB board has a second clearance concave arc surface to avoid the fourth spherical surface. The fourth clearance hole is located inside the second clearance concave arc surface. When the second signal transmission component 42 is in the second disconnected position, one end of the second drive rod 431 with the third plane extends into the second clearance concave arc surface. The third plane is lower than or flush with the surface of the side of the display unit facing the surface of the first signal PCB board.

[0111] During the assembly of two adjacent display units and the movement of the second signal transmission component 42 from the second disconnected position to the second connected position, the fourth spherical surface of the second force application component 33 can directly contact and engage with the third plane of the second drive rod 431, or the fourth spherical surface of the second force application component 33 can move on the surface of the fourth seat 41 facing the gold plating of the first signal PCB board and smoothly slide into the second relief concave arc surface to contact and engage with the third plane of the second drive rod 431, so that the second drive rod 431 moves to the left relative to the gold plating of the first signal PCB board and presses down the first end of the second rocker 432, so that the first end of the second rocker 432 swings around its axis, and the second end of the second rocker 432 pushes the second signal transmission component 42 to move to the right relative to the fourth seat 41, so that the second signal transmission component 42 is in the second connected position.

[0112] During the disassembly of two adjacent display units and the movement of the second signal transmission component 42 from the second on position to the second off position, a portion of the fourth spherical surface of the second force-applying component 33 slides on the second recessed arc surface and gradually separates from the third plane of the second drive rod 431. When the fourth spherical surface of the second force-applying component 33 is impacted, it can quickly retract into the second mounting base 34 to avoid interference with the fourth base 41, thus improving the smoothness of the disassembly process. After the first end of the second rocker 432 is pushed to the right, one end of the second drive rod 431 with the third plane re-extends into the second recessed arc surface. At the same time, the conductive post with the first spherical surface smoothly retracts into the fourth base 41 and separates from the input conductor 121 with the first plane, so that the second signal transmission component 42 is in the second off position.

[0113] During the assembly of the two adjacent display units, the second signal transmission element 42 can move along the fourth housing 41. Figure 5 The second signal transmission component 42 can float in the X-axis direction, and the second signal transmission component 42 can smoothly make point-to-surface contact with the first signal transmission component 32; the second force application component 33 can move along the second mounting base 34. Figure 5 The signal plug 40 floats along the X-axis, and the second force-applying component 33 can smoothly make point-to-surface contact with the second drive rod 431. There is no interference between the signal socket 30 and the signal plug 40, and the signal plug 40 can be quickly inserted into the signal socket 30. Similarly, during the disassembly process of the two adjacent display units, the signal plug 40 can be quickly separated from the signal socket 30. In this way, the signal plug 40 and the signal socket 30 can be automatically connected, enabling automatic signal transmission between the two display units without requiring manual insertion or removal of the signal plug 40 by on-site personnel, which is convenient for on-site personnel. Figure 5 The two display units are assembled or disassembled along the X-axis.

[0114] In this embodiment, the power plug 20, power socket 10, signal socket 30, and signal plug 40 are all assembled to the corresponding screw holes of the display unit by screws.

[0115] This application also provides an LED display device, such as... Figures 1 to 9 As shown, the LED display device of this embodiment includes a first display unit 51, a second display unit 52, a plug-in structure, and two LED display modules. The first display unit 51 and the second display unit 52 are arranged side by side, and the plug-in structure is the plug-in structure of the LED display device described above. Since the plug-in structure of the LED display device described above can solve the problem in the related art where the plug is prone to misalignment and difficult to insert into the socket, the LED display device with this plug-in structure can solve the same technical problem.

[0116] The power socket 10 of the plug-in mechanism is installed on the side adjacent to the first display unit 51 and the second display unit 52, and the power plug 20 of the plug-in mechanism is installed on the side adjacent to the second display unit 52 and the first display unit 51.

[0117] This application also provides an LED display device, such as... Figures 1 to 9 As shown, the LED display device of this embodiment includes a first display unit 51, a second display unit 52, a third display unit 53, and a fourth display unit 54, as well as a plug-in mechanism. The first display unit 51, the second display unit 52, the third display unit 53, and the fourth display unit 54 are arranged in an array and distributed sequentially along the circumference. The plug-in mechanism is the same as described above for the LED display device. Since the plug-in structure of the LED display device described above can solve the problem in related technologies where the plug is prone to misalignment and difficult to insert into the socket, the LED display device with this plug-in structure can solve the same technical problem.

[0118] The power socket 10 of the plug-in / plug-out mechanism is installed on the side adjacent to the first display unit 51 and the second display unit 52, and the power plug 20 of the plug-in / plug-out mechanism is installed on the side adjacent to the second display unit 52 and the first display unit 51. The signal socket 30 of the plug-in / plug-out mechanism is installed on the side adjacent to the first display unit 51 and the fourth display unit 54, and the signal plug 40 of the plug-in / plug-out mechanism is installed on the side adjacent to the fourth display unit 54 and the first display unit 51.

[0119] like Figures 1 to 9 As shown, the first display unit 51, the second display unit 52, the third display unit 53 and the fourth display unit 54 are all provided with through holes to avoid the power plug 20, the power socket 10, the signal socket 30 and the signal plug 40, so that the power plug 20 and the power socket 10 can be plugged into each other, and the signal socket 30 and the signal plug 40 can be plugged into each other.

[0120] In this embodiment, the first display unit 51, the second display unit 52, the third display unit 53, and the fourth display unit 54 each include a housing and a lamp panel module disposed on the front side of the housing, with a plug-in structure installed on the rear side of the housing. Of course, the plug-in structure can also be installed on the rear side of the lamp panel module.

[0121] like Figures 1 to 9 As shown, during the circumferential assembly of the fourth display unit 54, the third display unit 53, the second display unit 52, and the first display unit 51, the second conductive element 22 can move along the second base 21. Figure 3 The first conductive element 22 floats along the Y-axis direction, and the second conductive element 22 can smoothly make point-to-surface contact with the first conductive element 12; the first force-applying element 13 can move along the Y-axis direction within the first mounting base 14. Figure 3 The first force-applying component 13 can smoothly make point-to-surface contact with the first drive rod 231, and there is no interference between the power plug 20 and the power socket 10. The power plug 20 can be quickly inserted into the power socket 10 along any ray direction extending from the X-axis, Y-axis, or the vertex of the angle formed by the X-axis and Y-axis. At the same time, since the second signal transmission component 42 can move along the Y-axis direction within the fourth seat 41, the power plug 20 can be quickly inserted into the power socket 10. Figure 5 The second signal transmission component 42 can float in the X-axis direction, and the second signal transmission component 42 can smoothly make point-to-surface contact with the first signal transmission component 32; the second force application component 33 can move along the second mounting base 34. Figure 5 The first display unit 51 floats along the X-axis, and the second force-applying component 33 can smoothly make point-to-surface contact with the second drive rod 431. There is no interference between the signal socket 30 and the signal plug 40. The signal plug 40 can be quickly inserted into the signal socket 30 along any ray direction along the X-axis, Y-axis, or along the vertex of the angle formed by the X-axis and Y-axis. In this way, the power plug 20 and the power socket 10, as well as the signal socket 30 and the signal plug 40, can be simultaneously plugged in. The first display unit 51 can be quickly and accurately assembled onto the second display unit 52 and the fourth display unit 54 along any ray direction along the X-axis, Y-axis, or along the vertex of the angle formed by the X-axis and Y-axis.

[0122] Similarly, during the circumferential disassembly of the fourth display unit 54, the third display unit 53, the second display unit 52, and the first display unit 51, the power plug 20 can be quickly separated from the power socket 10 along any ray direction extending along the X-axis, Y-axis, or the vertex of the angle formed by the X-axis and Y-axis. The signal plug 40 can also be quickly separated from the signal socket 30 along any ray direction extending along the X-axis, Y-axis, or the vertex of the angle formed by the X-axis and Y-axis. Thus, the power plug 20 and the power socket 10, as well as the signal socket 30 and the signal plug 40, are simultaneously unplugged, allowing the first display unit 51 to be quickly and accurately detached from the second display unit 52 and the fourth display unit 54 along any ray direction extending along the X-axis, Y-axis, or the vertex of the angle formed by the X-axis and Y-axis. Furthermore, wireless (without flexible wires) connection and simultaneous insertion and removal of the plug-in structure in the X and Y directions can be realized between the fourth display unit 54, the third display unit 53, the second display unit 52 and the first display unit 51.

[0123] Of course, in the embodiment not shown in the figures, the signal socket of the plug-in mechanism is installed on the side adjacent to the first display unit and the second display unit. The signal plug of the plug-in mechanism is installed on the side adjacent to the second display unit and the first display unit.

[0124] It should be noted that, to further achieve simultaneous insertion and removal in the X and Y axes of the plug-in structure, it is necessary to ensure sufficient point-to-surface contact pressure between the second conductive element 22 and the first conductive element 12, while also ensuring sufficient point-to-surface contact pressure between the first force-applying element 13 and the first drive rod 231, to guarantee stable power and signal transmission. The force design between the power plug 20 and the power socket 10 is as follows: the maximum force of the first force-applying element 13 when pressed to the bottom is F1, and the minimum force of the first drive rod 231 is F2; ​​the force conversion ratio N of the first rocker 232; the theoretical contact pressure between the second conductive element 22 and the first conductive element 12 is F3; the compression reverse thrust of the third elastic element 27 is F4; the compression reverse force of the first elastic element 25 is F5; and the weight of the second conductive element 22 is G1. To ensure stable contact between the second conductive element 22 and the first conductive element 12, the above force relationship is: 2F2≥N(F3+F4+G1)+2F5. The force design between the signal plug 40 and the signal socket 30 is based on the same principle as the force design between the power plug 20 and the power socket 10, and will not be repeated here.

[0125] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description.
