Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. Based on the embodiments in the present invention, all other embodiments obtained by the operator of ordinary skill in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 to 6, the connector of the LED display device of the present embodiment includes: a first power supply insert 20. The first power supply plug-in unit 20 includes a first mounting seat 21, a first conductive member 22 movably disposed in the first mounting seat 21, a second conductive member 23 disposed in the first mounting seat 21, a driving member 24 disposed in the first mounting seat 21 and capable of driving the first conductive member 22 to move, and a reset member for 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 a side of the second conductive member 23 facing away from the first conductive member 22 has a protruding portion protruding from the first mounting seat 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 off position separated from the second conductive member 23.

By applying the technical solution of the present embodiment, the first conductive member 22 can be electrically connected to the control component, and the driving member 24 drives the first conductive member 22 to move, so that the first conductive member 22 has a first conduction position in conductive contact with the second conductive member 23. When the control assembly of the LED display device is electrically powered, the reset assembly applies a reset force to the first conductive member 22 so that the first conductive member 22 has a first off position separated from the second conductive member 23. At this time, although the protruding portion protrudes from the first mounting seat 21 along the moving direction of the first conductive member 22 and is exposed outside the LED display device, the second conductive member 23 is not powered because the first conductive member 22 and the second conductive member 23 are separated, and the second conductive member 23 is located in the moving direction of the first conductive member 22, so that the first conductive member 22 is not exposed outside the LED display device, and the operator is prevented from touching the LED display device by mistake because the second conductive member 23 can shield the first conductive member 22 in the moving direction. Therefore, the technical scheme of the embodiment effectively solves the problem that the plug connector in the related art is exposed outside the LED display device, and an operator mistakenly touches the plug connector to cause electric shock.

In this embodiment, the control component includes a power board and a control circuit electrically connected to the power board, and the control circuit is electrically connected to the first conductive member 22.

As shown in fig. 1 to 6, the connector of the LED display device further includes a second power supply plug 30 positioned at one side of the first power supply plug 20. The second power supply plug-in unit 30 includes a second mounting seat 31 and a third conductive member 32 penetrating the second mounting seat 31, and the second conductive member 23 is floatably disposed on the first mounting seat 21. The second conductive member 23 has a second conductive position in conductive contact with the third conductive member 32 and a second off position separated from the third conductive member 32. The second power supply plug-in unit 30 of the connector of the LED display device may be disposed on the first side 11 of one display unit 10 of the two adjacent display units 10 adjacent to the other display unit 10, the first power supply plug-in unit 20 of the connector of the LED display device may be disposed on the second side 12 of the other display unit 10 of the two adjacent display units 10 adjacent to the one display unit 10, and 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 in a direction close to the first conductive member 22, so that the second conductive member 23 moves to a second conduction position in conductive contact with the third conductive member 32. And the second mounting seat 31 contacts the driving member 24 and drives the driving member 24 to move, so that the driving member 24 drives the first conductive member 22 to move, so that the first conductive member 22 moves to the first conduction position in conductive contact with the second conductive member 23. Because the second conductive member 23 is located at the second conduction position and is located at the first conduction position before the first conductive member 22, there is a precedence order, and only when the second conductive member 23 is located at the second conduction position and the first conductive member 22 is located at the first conduction position, the power on the first power supply plug-in unit 20 can be conducted to the second power supply plug-in unit 30, so that the risk of mistaken touch during the process that the second conductive member 23 is located at the second conduction position and the first conductive member 22 is located at the first conduction position is avoided for an operator. In addition, when two adjacent display units 10 are assembled, the first conductive piece 22, the second conductive piece 23 and the third conductive piece 32 are directly electrically connected after being conducted through the mutual insertion of the first power supply plug-in piece 20 and the second power supply plug-in piece 30, wiring operation which needs to be carried out when flexible power supply wires are connected is not needed, complicated wiring when the power supply wires are connected is avoided, the two adjacent display units 10 are more conveniently assembled, and the assembly efficiency is improved. When two adjacent display units 10 are disassembled, the third conductive member 32 does not contact the second conductive member 23, and the third conductive member 32 is in a separated second off position. And, the second mounting seat 31 does not contact the driving member 24, the first conductive member 22 does not have a driving force applied by the driving member 24, the first conductive member 22 starts to reset under the resetting force of the resetting member, the first conductive member 22 moves in a direction away from the second conductive member 23, so that the first conductive member 22 moves to a first off position separated from the second conductive member 23, at this time, the second power supply plug-in unit 30 is separated from the first power supply plug-in unit 20, and two adjacent display units 10 can be separated.

As shown in fig. 1 to 6, the reset member is a first elastic member 25 disposed between the first conductive member 22 and the second conductive member 23, and the first elastic member 25 simultaneously applies a first elastic force to the first conductive member 22 and the second conductive member 23, wherein the first elastic force applied to the first conductive member 22 by the first elastic member 25 forms a reset force. Thus, when two adjacent display units 10 are detached, the first elastic member 25 simultaneously applies the first elastic force to the first conductive member 22 and the second conductive member 23, and the second conductive member 23 moves in a direction away from the first conductive member 22, and at the same time, the first conductive member 22 moves in a direction away from the second conductive member 23, so that the first conductive member 22 moves to the first off position separated from the second conductive member 23. In this way, the first conductive member 22 can be quickly placed in the first open position, reducing the risk of accidental contact by an operator. The first elastic member 25 is preferably a first compression spring.

As shown in fig. 1 to 3, 6 and 7, when two adjacent display units 10 are assembled together, in order to facilitate rapid insertion of the second conductive member 23 and the third conductive member 32, a positioning structure is provided between the second conductive member 23 and the third conductive member 32.

As shown in fig. 1 to 3, 6 and 7, the second conductive member 23 includes an insulator 231 and a first conductive member 232 penetrating the insulator 231, and the third conductive member 32 includes a second conductive member 322 penetrating the second mounting seat 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 seat 31. Thus, when the second conductive member 23 and the third conductive member 32 are inserted into each other, the positioning protrusion 323 and the positioning groove 233 are positioned and matched, so that the third conductive member 32 is inserted into the second conductive member 23 more accurately.

Specifically, the insulator 231 includes an insulating block floatably disposed in the first mounting seat 21 and a protrusion disposed on a side of the insulating block facing away from the first conductive member 22, the protrusion forming the protruding portion. One end of the first conductor 232, which can be in contact with the second conductor 322, extends into the protrusion, the positioning groove 233 is disposed on the surface of the protrusion facing away from the first conductive member 22, and one end of the first conductor 232, which can be in contact with the second conductor 322, is located in the positioning groove 233. When the second conductive member 23 and the third conductive member 32 are inserted into each other, 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 is in conductive contact with the end of the second conductive member 322 that can contact the first conductive member 232.

Of course, in an embodiment not shown in the drawings, the positioning projection is provided on the insulator and the positioning groove is provided on the second mount.

In this embodiment, the first conductor 232 is a copper pillar that can completely float in the insulator 231, the insulator 231 is provided with a mounting hole for mounting and clearance-fitting the copper pillar, a copper bush is fixed in the mounting hole, a third compression spring is arranged in the copper bush, and the hole wall of the copper bush performs elastic force limitation on the third compression spring. The machining processes of the copper sleeve, the third compression spring and the copper cylinder are as follows: and putting the copper cylinder into the copper sleeve, putting the third compression spring into the copper sleeve, and sewing the copper sleeve in a riveting and closing-up manner to form the spring needle.

As shown in fig. 1 to 3, 6 and 7, a guide structure is further disposed between the first conductive member 22 and the second conductive member 23. The guiding structure includes a guiding post 221 and a guiding hole 234 for the guiding post 221 to penetrate, the guiding post 221 is disposed on the first conductive member 22, and the guiding hole 234 is disposed on the second conductive member 23. Thus, the guide post 221 moves along the axial direction of the guide hole 234, and the first conductive member 22 is prevented from deflecting during the movement relative to the second conductive member 23, so that the movement of the first conductive member 22 relative to the second conductive member 23 is more stable. The guide post 221 is in guiding fit with the guide hole 234, so that the guide structure is simple in structure and low in cost.

Of course, in embodiments not shown in the figures, the guide holes are provided on the first conductive member and the guide posts are provided on the second conductive member.

As shown in fig. 1, 2, 6 and 7, the first power supply package 20 further includes a second elastic member 26 disposed between the second conductive member 23 and the first mounting seat 21, and 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. In this way, when the two adjacent display units 10 are assembled together, the first conductive member 22 is in the first conducting position and the second conductive member 23 is in the second conducting position, the second conductive member 23 can be stably and evenly positioned between the first conductive member 22 and the third conductive member 32 and can be stably maintained in the second conducting position under the combined action of the second power supply plug-in unit 30 pressing down the second conductive member 23 and the first elastic force and the second elastic force.

When two adjacent display units 10 are disassembled, the first conductive member 22 and the second conductive member 23 are simultaneously subjected to the first elastic force, and the second conductive member 23 is also subjected to the second elastic force, so that the second conductive member 23 is rapidly separated from the first conductive member 22, so that the first conductive member 22 is rapidly moved to the first disconnection position separated from the second conductive member 23. In this way, the first conductive member 22 can be quickly placed in the first open position, greatly reducing the risk of operator error. The second elastic member 26 is preferably a second compression spring.

As shown in fig. 1, fig. 2, fig. 6 and fig. 7, the driving member 24 includes a push rod 241 movably disposed on the first mounting seat 21 and a lever 242 rotatably disposed on the first mounting seat 21 through a rotating shaft 27. The first end of the lever 242 abuts against the first end of the push rod 241, the second end of the lever 242 abuts against the first conductive member 22, the second end of the push rod 241 is connected to the second conductive member 23, and the second conductive member 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 member 22 to move from the first off position to the first on position. Thus, the pushing force applied by the driving member 24 to the first conductive member 22 is facilitated by the cooperation between the push rod 241, the lever 242 and the rotation shaft 27, and the moving process of the first conductive member 22 is facilitated.

As shown in fig. 1 to 3, 6 and 7, the first mounting seat 21 includes a first side plate 211 and a second side plate 212 arranged at an interval, and a connecting plate 213 connected to ends of the first side plate 211 and the second side plate 212 far away from the first conductive piece 22. The length of the first side plate 211 in the moving direction of the first conductive piece 22 is greater than the length of the second side plate 212 in the moving direction of the first conductive piece 22. An installation space is defined among the first side plate 211, the connecting plate 213 and the second side plate 212. Wherein a part of the first conductive member 22 and another part of the second conductive member 23 are located in the installation space. Thus, the installation space is provided to limit the moving range of a portion of the first conductive member 22 and another portion of the second conductive member 23, facilitating smooth movement of the first conductive member 22 and the second conductive member 23 in the installation space. The push rod 241 is movably disposed through the connecting plate 213, the rotating shaft 27 is disposed on the first side plate 211 and located outside the installation space, and the lever 242 is located outside the installation space. Thus, the lever 242 has a sufficient space for rotation, which facilitates the rotation of the lever 242 on the rotation shaft 27. A connecting rod 222 is arranged on the side of the first conductive member 22 away from the second conductive member 23, a first end of the push rod 241 is hinged with a first end of the lever 242, and one end of the connecting rod 222 is hinged with a second end of the lever 242. Thus, the first end of the push rod 241 pushes the first end of the lever 242 to be rotatable about the rotating shaft 27, and the second end of the lever 242 rotates about the rotating shaft 27 and causes the second end of the lever 242 to push one end of the connecting rod 222 to move in a direction opposite to the pushing direction of the push rod 241.

As shown in fig. 1 to fig. 3, in particular, the push rod 241 is connected to the nut 28 through the connection plate 213, and the nut 28 can cooperate with a stop at a side of the connection plate 213 away from the second conductive member 23. When the second conductive member 23 is at the second off position, the nut 28 is engaged with the connection plate 213 to prevent the second conductive member 23 from falling out of the installation space. At this time, the first and second elastic members 25 and 26 support the second conductive member 23 so that the second conductive member 23 can be maintained at the second off position to prevent the second conductive member 23 from moving toward the first conductive member 22.

As shown in fig. 4 to 7, in the present embodiment, one display unit 10 of two adjacent display units 10 is an upper display unit, and the other display unit 10 is a lower display unit. The second power supplying plug-in 30 is connected to the upper display unit, and the first power supplying plug-in 20 is connected to the lower display unit. When the upper display unit and the lower display unit are assembled together, the positioning protrusion 323 of the second power supply package 30 is inserted into the positioning groove 233 of the first power supply package 20 for positioning engagement and continues to press the first power supply package 20 downward, wherein the second conductor 322 contacts the first conductor 232 and continues to press downward with a certain pressure while the push rod 241 moves downward. The upper display unit is pressed down and the first elastic force acts to ensure the contact between the second conductor 322 and the first conductor 232 and to ensure a certain pressure. Simultaneous continued downward pressure on the first conductor 232 and the second conductor 322 maintains contact and pressure at all times while simultaneously moving downward. The push rod 241 moves downward to rotate the first end of the lever 242 around the rotating shaft 27, the synchronous push rod 241 compresses the second elastic member 26, and the second end of the lever 242 rotates around the rotating shaft 27 to make the second end of the lever 242 push one end of the connecting rod 222 to move the connecting rod 222 upward. The connecting rod 222 moves upward to drive the first conductive member 22 to move upward, the conductive body of the first conductive member 22 moves upward and contacts and is compressed with the lower end of the first conductive body 232, so that the conductive body of the first conductive member 22 is in contact conduction with the first conductive body 232, and simultaneously the second conductive body 322 and the first conductive body 232 synchronously realize contact conduction according to synchronous action, so that the electrical connection between the second power supply plug-in unit 30 and the first power supply plug-in unit 20 is realized, and the assembly of the upper display unit and the lower display unit is further realized.

In this embodiment, when the upper display unit and the lower display unit are detached, the second power supply plug 30 is separated from the first power supply plug 20, the external force of the second conductive member 23 and the push rod 241 is simultaneously lost, the first elastic member 25 and the second elastic member 26 are simultaneously restored, the first conductive member 22 is restored to the first off position, and the protrusion portion is restored to the state of protruding from the first mounting seat 21 without being subjected to the external force. Wherein when the upper display unit is detached from the lower display unit and separated from the lower display unit step by step. The upper display unit is no longer pressed against the push rod 241 and gradually gets away from the lower display unit, the upper display unit is synchronously kept away from the lower display unit, the pressure between the third conductive member 32 and the second conductive member 23 gradually disappears and separates, when the synchronous push rod 241 has no pressure, the second conductive member 23 drives the push rod 241 to reset upwards under the action of the second elastic member 26, the lever 242 resets to the balance position under the action of the push rod 241, the first conductive member 22 synchronously moves downwards under the action of the push rod 241 and the first elastic member 25 and resets to the first disconnection position, the upper display unit is far away from the second conductive member 23, the second conductive member 23 resets to the position protruding out of the first mounting seat 21, the second power supply plug-in unit 30 and the first power supply plug-in unit 20 are completely disconnected, and further the upper display unit and the lower display unit are separated. In this way, in the process of assembling two adjacent display units 10, the automatic electrical connection between the first power supply plug-in 20 and the second power supply plug-in 30 is realized, no additional driving operation is required, and the assembly or disassembly of the two display units 10 of an operator is facilitated.

As shown in fig. 4 to 8, the LED display device of the present embodiment includes a plurality of display units 10 and a connector disposed between two adjacent display units 10, where the connector is the connector of the LED display device.
