Technical Field

[0001] This invention relates to the field of LED display technology, and more specifically, to a connector for an LED display device and an LED display device. Background Technology

[0002] LED display devices are flat panel displays used to display various information such as text, images, videos, and recorded signals.

[0003] LED display devices include control components and connectors electrically connected to the control components. When the control components of the LED display device are powered on for testing, the connectors are energized, and the exposed parts are located outside the LED display device, posing a risk of electric shock to operators who accidentally touch the connectors. Summary of the Invention

[0004] The main objective of this invention is to provide a connector for an LED display device and an LED display device in order to solve the problem in related technologies where the connectors are exposed on the outside of the LED display device, leading to electric shock due to accidental contact with the connectors by operators.

[0005] To achieve the above objectives, according to one aspect of the present invention, a connector for an LED display device is provided, comprising: a first power supply plug, including a first mounting base, a first conductive member movably disposed within the first mounting base, a second conductive member disposed in the first mounting base, a driving member disposed in the first mounting base and capable of driving the first conductive member to move, and a reset member applying a reset force to the first conductive member, wherein the second conductive member is located in the moving direction of the first conductive member, and the side of the second conductive member opposite to the first conductive member has a protrusion protruding from the first mounting base along the moving direction of the first conductive member, wherein the driving member drives the first conductive member to move so that the first conductive member has a first conductive position in conductive contact with the second conductive member, and the reset member applies a reset force to the first conductive member so that the first conductive member has a first disconnected position separated from the second conductive member.

[0006] Furthermore, the connector of the LED display device also includes a second power supply plug located on one side of the first power supply plug. The second power supply plug includes a second mounting base and a third conductive member passing through the second mounting base. The second conductive member is buoyantly disposed on the first mounting base. The second conductive member has a second conductive position that is in conductive contact with the third conductive member and a second disconnected position that is separated from the third conductive member. The second conductive member is in the second conductive position before the first conductive member is in the first conductive position.

[0007] Furthermore, the reset member is a first elastic member disposed between the first conductive member and the second conductive member. The first elastic member applies a first elastic force to both the first conductive member and the second conductive member simultaneously, wherein the first elastic force applied by the first elastic member to the first conductive member forms a reset force.

[0008] Furthermore, a positioning structure is provided between the second conductive element and the third conductive element.

[0009] Furthermore, the second conductive element includes an insulator and a first conductive element passing through the insulator, the third conductive element includes a second conductive element passing through the second mounting base, and the positioning structure includes a positioning groove and a positioning protrusion inserted into the positioning groove. One of the positioning groove and the positioning protrusion is disposed on the insulator, and the other of the positioning groove and the positioning protrusion is disposed on the second mounting base.

[0010] Furthermore, a guide structure is provided between the first conductive element and the second conductive element. The guide structure includes a guide post and a guide hole through which the guide post passes. One of the guide post and the guide hole is provided on the first conductive element, and the other of the guide post and the guide hole is provided on the second conductive element.

[0011] Furthermore, the first power supply plug also includes a second elastic member disposed between the second conductive member and the first mounting base, the second elastic member applying a second elastic force to the second conductive member in a direction away from the first conductive member.

[0012] Furthermore, the driving component includes a push rod movably disposed on the first mounting base and a lever rotatably disposed on the first mounting base via a rotating shaft. The first end of the lever abuts against the first end of the push rod, the second end of the lever abuts against the first conductive element, and the second end of the push rod is connected to the first mounting base. The second conductive element drives the push rod to push the lever to rotate around the rotating shaft, so that the lever pushes the first conductive element to move from the first disconnected position to the first connected position.

[0013] Furthermore, the first mounting base includes a first side plate and a second side plate spaced apart, and a connecting plate connected to the first side plate and the second side plate at the end away from the first conductive element. The length of the first side plate along the moving direction of the first conductive element is greater than the length of the second side plate along the moving direction of the first conductive element. The first side plate, the connecting plate, and the second side plate form an installation space, wherein a portion of the first conductive element and another portion of the second conductive element are located within the installation space. The push rod is movably inserted through the connecting plate. The rotating shaft is disposed on the first side plate and located outside the installation space. The lever is located outside the installation space. A connecting rod is disposed on the side of the first conductive element away from the second conductive element. The first end of the push rod is hinged to the first end of the lever, and the first end of the connecting rod is hinged to the second end of the lever.

[0014] According to another aspect of the present invention, an LED display device is provided, comprising a plurality of display units and a connector disposed between two adjacent display units. The connector is the connector of the aforementioned LED display device. A second power supply plug of the connector is disposed on a first side adjacent to one of the two adjacent display units. The first power supply plug of the connector is disposed on a second side adjacent to one of the two adjacent display units. A first clearance hole for a third conductive member of the connector is provided on the first side. A second clearance hole for a second conductive member of the connector is provided on the second side. A third clearance hole for a driving member of the connector is also provided on the second side.

[0015] According to the technical solution of this invention, the connector of the LED display device includes a first power supply plug. The first power supply plug includes a first mounting base, a first conductive member movably disposed within the first mounting base, a second conductive member disposed on the first mounting base, a driving member disposed on the first mounting base and capable of driving the first conductive member to move, and a reset member applying a reset force to the first conductive member. The second conductive member is located in the moving direction of the first conductive member, and the side of the second conductive member opposite to the first conductive member has a protrusion extending out of the first mounting base along the moving direction of the first conductive member. In this application, the first conductive member can be electrically connected to a control component. The driving member drives the first conductive member to move, so that the first conductive member has a first conductive position in conductive contact with the second conductive member. When the control component of the LED display device is powered on for testing, the reset member applies a reset force to the first conductive member, so that the first conductive member has a first disconnected position separated from the second conductive member. Although the protrusion protrudes from the first mounting base and is exposed outside the LED display device, the first conductive element and the second conductive element are separated. The second conductive element is not energized, and because it is located in the direction of movement of the first conductive element, it can shield the first conductive element in that direction, preventing the first conductive element from being exposed outside the LED display device and avoiding accidental contact by the operator. Therefore, the technical solution of this application effectively solves the problem in related technologies where the connector is exposed outside the LED display device, leading to electric shock due to accidental contact by the operator.

[0029] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] like Figures 1 to 6 As shown, the connector of the LED display device in this embodiment includes a first power supply plug 20. The first power supply plug 20 includes a first mounting base 21, a first conductive member 22 movably disposed within the first mounting base 21, a second conductive member 23 disposed on the first mounting base 21, a driving member 24 disposed on the first mounting base 21 and capable of driving the first conductive member 22 to move, and a reset member applying a reset force to the first conductive member 22. The second conductive member 23 is located in the moving direction of the first conductive member 22, and the side of the second conductive member 23 opposite to the first conductive member 22 has a protrusion extending out of the first mounting base 21 along the moving direction of the first conductive member 22. The driving member 24 drives the first conductive member 22 to move, so that the first conductive member 22 has a first conductive position in conductive contact with the second conductive member 23, and the reset member applies a reset force to the first conductive member 22, so that the first conductive member 22 has a first disconnected position separated from the second conductive member 23.

[0031] By applying the technical solution of this embodiment, the first conductive element 22 can be electrically connected to the control component, and the driving element 24 drives the first conductive element 22 to move, so that the first conductive element 22 has a first conductive position in which it makes conductive contact with the second conductive element 23. When the control component of the LED display device is powered on for testing, the reset element applies a reset force to the first conductive element 22, so that the first conductive element 22 has a first disconnected position separated from the second conductive element 23. At this time, although the protrusion protrudes from the first mounting base 21 along the moving direction of the first conductive element 22 and is exposed outside the LED display device, since the first conductive element 22 and the second conductive element 23 have been separated, the second conductive element 23 is not energized, and since the second conductive element 23 is located in the moving direction of the first conductive element 22, the second conductive element 23 can block the first conductive element 22 in the moving direction, so that the first conductive element 22 is not exposed outside the LED display device, avoiding accidental contact by the operator. Therefore, the technical solution of this embodiment effectively solves the problem in the related art where the connector is exposed outside the LED display device, and the operator accidentally touches the connector, resulting in electric shock.

[0032] In this embodiment, the control component includes a power board and control lines electrically connected to the power board, and the control lines are electrically connected to the first conductive element 22.

[0033] like Figures 1 to 6 As shown, the connector of the LED display device also includes a second power supply plug 30 located on one side of the first power supply plug 20. The second power supply plug 30 includes a second mounting base 31 and a third conductive member 32 passing through the second mounting base 31. The second conductive member 23 is buoyantly disposed on the first mounting base 21. The second conductive member 23 has a second conductive position that is in conductive contact with the third conductive member 32 and a second disconnected position that is separated from the third conductive member 32. The second power supply plug 30 of the connector of the LED display device can be disposed on a first side 11 adjacent to one of two adjacent display units 10 and the other display unit 10, and the first power supply plug 20 of the connector of the LED display device can be disposed on a second side 12 adjacent to the other display unit 10 and the first display unit 10. When the two adjacent display units 10 are assembled together, the third conductive member 32 contacts the second conductive member 23 and drives the second conductive member 23 to move towards the first conductive member 22, so that the second conductive member 23 moves to the second conductive position that is in conductive contact with the third conductive member 32. Furthermore, the second mounting base 31 contacts the driving member 24 and drives the driving member 24 to move, causing the driving member 24 to drive the first conductive member 22 to move to the first conductive position where it makes contact with the second conductive member 23. Since the second conductive member 23 is in the second conductive position before the first conductive member 22 is in the first conductive position, there is a sequential order. Only when the second conductive member 23 is in the second conductive position and the first conductive member 22 is in the first conductive position can the electricity on the first power supply plug 20 be conducted to the second power supply plug 30. This avoids the risk of accidental contact by the operator during the process where the second conductive member 23 is in the second conductive position and the first conductive member 22 is in the first conductive position. Furthermore, during the assembly of two adjacent display units 10, the first conductive element 22, the second conductive element 23, and the third conductive element 32 are directly electrically connected through the insertion of the first power supply plug 20 and the second power supply plug 30. This eliminates the need for wiring operations required when using flexible power cables, avoiding complex wiring during power cable connections. This simplifies the assembly of the two adjacent display units 10 and improves assembly efficiency. When the two adjacent display units 10 are disassembled, the third conductive element 32 does not contact the second conductive element 23, and the third conductive element 32 is in the second disconnected position. Also, the second mounting base 31 does not contact the driving element 24, and there is no driving force applied by the driving element 24 to the first conductive element 22. Under the reset force of the reset element, the first conductive element 22 begins to reset and moves away from the second conductive element 23, so that the first conductive element 22 moves to the first disconnected position separated from the second conductive element 23. At this time, the second power supply plug 30 and the first power supply plug 20 separate, and the two adjacent display units 10 can be separated.

[0034] like Figures 1 to 6 As shown, the reset element is a first elastic element 25 disposed between the first conductive element 22 and the second conductive element 23. The first elastic element 25 simultaneously applies a first elastic force to both the first conductive element 22 and the second conductive element 23, wherein the first elastic force applied by the first elastic element 25 to the first conductive element 22 forms a reset force. Thus, when two adjacent display units 10 are disassembled, the first elastic element 25 simultaneously applies the first elastic force to both the first conductive element 22 and the second conductive element 23. The second conductive element 23 moves away from the first conductive element 22, while the first conductive element 22 moves away from the second conductive element 23, causing the first conductive element 22 to move to a first disconnected position separated from the second conductive element 23. This allows the first conductive element 22 to quickly reach the first disconnected position, reducing the risk of accidental operation by the operator. The aforementioned first elastic element 25 is preferably a first compression spring.

[0035] like Figures 1 to 3 , Figure 6 and Figure 7 As shown, when two adjacent display units 10 are assembled together, a positioning structure is provided between the second conductive element 23 and the third conductive element 32 to facilitate quick insertion of the second conductive element 23 and the third conductive element 32.

[0036] like Figures 1 to 3 , Figure 6 and Figure 7 As shown, the second conductive element 23 includes an insulator 231 and a first conductive element 232 passing through the insulator 231, and the third conductive element 32 includes a second conductive element 322 passing through the second mounting base 31. The positioning structure includes a positioning groove 233 and a positioning protrusion 323 inserted into the positioning groove 233. The positioning groove 233 is disposed on the insulator 231, and the positioning protrusion 323 is disposed on the second mounting base 31. In this way, when the second conductive element 23 and the third conductive element 32 are inserted, the positioning protrusion 323 and the positioning groove 233 perform positioning cooperation, so that the third conductive element 32 can be inserted more accurately with the second conductive element 23.

[0037] Specifically, the insulator 231 includes an insulating block buoyantly disposed within the first mounting base 21 and a protrusion disposed on the side of the insulating block opposite to the first conductive member 22, the protrusion forming the aforementioned protrusion. One end of the first conductive member 232 that can contact the second conductive member 322 extends into the protrusion, and a positioning groove 233 is disposed on the surface of the protrusion on the side opposite to the first conductive member 22, with the end of the first conductive member 232 that can contact the second conductive member 322 located within the positioning groove 233. When the second conductive member 23 and the third conductive member 32 are inserted, the positioning protrusion 323 is inserted into the positioning groove 233, and the end of the first conductive member 232 that can contact the second conductive member 322 makes conductive contact with the end of the second conductive member 322 that can contact the first conductive member 232.

[0038] Of course, in embodiments not shown in the figures, the positioning protrusion is provided on the insulator, and the positioning groove is provided on the second mounting base.

[0039] In this embodiment, the first conductor 232 is a copper pillar that can float completely within the insulator 231. The insulator 231 has mounting holes for installing the copper pillar and for clearance fitting. A copper sleeve is fixed inside the mounting holes, and a third compression spring is disposed inside the copper sleeve. The hole wall of the copper sleeve provides elastic restraint for the third compression spring. The processing of the copper sleeve, the third compression spring, and the copper pillar is as follows: the copper pillar is placed into the copper sleeve, then the third compression spring is placed in, and then the copper sleeve is sewn together by riveting to form a spring needle.

[0040] like Figures 1 to 3 , Figure 6 and Figure 7 As shown, a guide structure is also provided between the first conductive element 22 and the second conductive element 23. The guide structure includes a guide post 221 and a guide hole 234 through which the guide post 221 passes. The guide post 221 is disposed on the first conductive element 22, and the guide hole 234 is disposed on the second conductive element 23. In this way, the guide post 221 moves along the axial direction of the guide hole 234, preventing the first conductive element 22 from deviating relative to the second conductive element 23 during movement, thus ensuring smoother movement of the first conductive element 22 relative to the second conductive element 23. The guide post 221 and the guide hole 234 provide a guiding fit, resulting in a simple structure and low cost for the guide structure.

[0041] Of course, in the embodiment not shown in the figure, the guide hole is disposed on the first conductive element and the guide post is disposed on the second conductive element.

[0042] like Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, the first power supply plug 20 also includes a second elastic member 26 disposed between the second conductive member 23 and the first mounting base 21. The second elastic member 26 applies a second elastic force to the second conductive member 23 in a direction away from the first conductive member 22. Thus, when two adjacent display units 10 are assembled together, with the first conductive member 22 in the first conductive position and the second conductive member 23 in the second conductive position, the second power supply plug 30 pressing down on the second conductive member 23, along with the combined action of the first and second elastic forces, allows the second conductive member 23 to be balanced and stably positioned between the first conductive member 22 and the third conductive member 32, and to be smoothly maintained in the second conductive position.

[0043] When two adjacent display units 10 are disassembled, the first conductive element 22 and the second conductive element 23 are simultaneously subjected to a first elastic force, and the second conductive element 23 is also subjected to a second elastic force. This causes the second conductive element 23 to move rapidly away from the first conductive element 22, allowing the first conductive element 22 to quickly move to a first disconnected position separated from the second conductive element 23. In this way, the first conductive element 22 can quickly reach the first disconnected position, greatly reducing the risk of accidental contact by the operator. The aforementioned second elastic element 26 is preferably a second compression spring.

[0044] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the driving component 24 includes a push rod 241 movably mounted on the first mounting base 21 and a lever 242 rotatably mounted on the first mounting base 21 via a rotating shaft 27. The first end of the lever 242 abuts against the first end of the push rod 241, and the second end of the lever 242 abuts against the first conductive element 22. The second end of the push rod 241 is connected to the second conductive element 23. The second conductive element 23 drives the push rod 241 to push the lever 242 to rotate around the rotating shaft 27, so that the lever 242 pushes the first conductive element 22 from a first disconnected position to a first connected position. Thus, the cooperation between the push rod 241, the lever 242, and the rotating shaft 27 facilitates the pushing force applied by the driving component 24 to the first conductive element 22, making the movement of the first conductive element 22 more convenient.

[0045] like Figures 1 to 3 , Figure 6 and Figure 7As shown, the first mounting base 21 includes a first side plate 211 and a second side plate 212 spaced apart, and a connecting plate 213 connected to the end of the first side plate 211 and the second side plate 212 away from the first conductive element 22. The length of the first side plate 211 along the moving direction of the first conductive element 22 is greater than the length of the second side plate 212 along the moving direction of the first conductive element 22. The first side plate 211, the connecting plate 213, and the second side plate 212 form a mounting space. A portion of the first conductive element 22 and another portion of the second conductive element 23 are located within the mounting space. This mounting space limits the movement range of the portion of the first conductive element 22 and the other portion of the second conductive element 23, facilitating smooth movement of the first conductive element 22 and the second conductive element 23 within the mounting space. A push rod 241 is movably inserted through the connecting plate 213, a rotating shaft 27 is mounted on the first side plate 211 and located outside the mounting space, and a lever 242 is located outside the mounting space. This provides sufficient room for lever 242 to rotate on shaft 27. A connecting rod 222 is located on the side of the first conductive element 22 opposite to the second conductive element 23. The first end of push rod 241 is hinged to the first end of lever 242, and one end of connecting rod 222 is hinged to the second end of lever 242. Thus, the first end of push rod 241 pushes the first end of lever 242 to rotate around shaft 27, and the second end of lever 242 rotates around shaft 27, causing the second end of lever 242 to push one end of connecting rod 222 in the opposite direction to the pushing direction of push rod 241.

[0046] like Figures 1 to 3 As shown, specifically, a nut 28 is connected to the portion of the push rod 241 that passes through the connecting plate 213. The nut 28 can engage with a stop on the side of the connecting plate 213 opposite to the second conductive member 23. When the second conductive member 23 is in the second disconnected position, the nut 28 engages with the stop on the connecting plate 213 to prevent the second conductive member 23 from dislodging from the installation space. At this time, the first elastic member 25 and the second elastic member 26 support the second conductive member 23 so that the second conductive member 23 can be held in the second disconnected position, preventing the second conductive member 23 from moving towards the first conductive member 22.

[0047] like Figures 4 to 7As shown, in this embodiment, one of the two adjacent display units 10 is the upper display unit, and the other is the lower display unit. The second power supply plug 30 is connected to the upper display unit, and the first power supply plug 20 is connected to the lower display unit. When the upper and lower display units are assembled together, the positioning protrusion 323 of the second power supply plug 30 is inserted into the positioning groove 233 of the first power supply plug 20 for positioning and engagement, and the first power supply plug 20 continues to be pressed downwards. Simultaneously, as the push rod 241 moves downwards, the second conductor 322 contacts the first conductor 232 and continues to press downwards to maintain a certain pressure. The downward pressure of the upper display unit and the action of the first elastic force ensure contact between the second conductor 322 and the first conductor 232, maintaining a certain pressure. Simultaneously pressing downwards, the first conductor 232 and the second conductor 322 maintain contact and pressure, moving downwards synchronously. The push rod 241 moves downward, causing the first end of the lever 242 to rotate around the pivot 27. Simultaneously, the push rod 241 compresses the second elastic element 26, and the second end of the lever 242 rotates around the pivot 27, pushing one end of the connecting rod 222 to move the connecting rod 222 upward. The upward movement of the connecting rod 222 causes the first conductive element 22 to move upward. The conductor of the first conductive element 22 moves upward and contacts and is compressed with the lower end of the first conductive element 232, achieving contact and conduction between the conductor of the first conductive element 22 and the first conductive element 232. At the same time, the second conductive element 322, which is associated with the synchronous action, has also achieved contact and conduction with the first conductive element 232, thus realizing the electrical connection between the second power supply plug 30 and the first power supply plug 20, further realizing the assembly of the upper display unit and the lower display unit.

[0048] In this embodiment, when the upper display unit and the lower display unit are disassembled, the second power supply plug 30 separates from the first power supply plug 20, the external force on the second conductive member 23 and the push rod 241 is simultaneously lost, and the first elastic member 25 and the second elastic member 26 simultaneously reset, causing the first conductive member 22 to reset to the first disconnected position, and the protrusion returns to its state of not being subjected to external force and protruding from the first mounting base 21. This occurs when the upper display unit is gradually disassembled from the lower display unit and separated from it. As the upper display unit moves away from the push rod 241 and gradually moves away from the lower display unit, the pressure between the third conductive element 32 and the second conductive element 23 gradually disappears and separates. Simultaneously, when the push rod 241 is no longer under pressure, the second conductive element 23, under the action of the second elastic element 26, drives the push rod 241 to return to its original position. The lever 242 returns to its equilibrium position due to the action of the push rod 241. Simultaneously, under the action of the push rod 241 and the first elastic element 25, the first conductive element 22 moves downward to its original position and returns to the first disconnected position. The upper display unit moves away from the second conductive element 23, and the second conductive element 23 returns to its original position protruding from the first mounting base 21. The second power supply plug 30 and the first power supply plug 20 are completely disconnected, further separating the upper and lower display units. In this way, during the assembly of two adjacent display units 10, the first power supply plug 20 and the second power supply plug 30 are automatically electrically connected without additional driving operations, facilitating the assembly or disassembly of the two display units 10 by the operator.

[0049] This application also provides an LED display device, such as... Figures 4 to 8 As shown, the LED display device of this embodiment includes a plurality of display units 10 and a connector disposed between two adjacent display units 10. The connector is the connector of the aforementioned LED display device.
