[0030] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] Example 1:

[0032] like Figure 1 As shown, the first connector 1 provided in an embodiment of the present invention includes a mounting plate 11, a cover plate 12, a first AC terminal 15, a first DC terminal 16 and a first signal terminal 17. The first AC terminal 15, the first DC terminal 16 and the first signal terminal 17 are passed through the cover plate 12. The cover plate 12 is fixed on the mounting plate 11. The mounting plate 11 is used to be fixedly connected to the first electronic device.

[0033] The inner end of the first AC terminal 15 is used to electrically connect to the first electronic device, and the outer end of the first AC terminal 15 is used to electrically connect to the second connector 2 electrically connected to the second electronic device, so as to form an AC path between the first electronic device, the first connector 1, the second connector 2, and the second electronic device.

[0034] The inner end of the first DC terminal 16 is used to electrically connect to the first electronic device, and the outer end of the first DC terminal 16 is used to electrically connect to the second connector 2 electrically connected to the second electronic device, so as to form a DC path between the first electronic device, the first connector 1, the second connector 2, and the second electronic device.

[0035] The inner end of the first signal terminal 17 is used to electrically connect to the first electronic device, and the outer end of the first signal terminal 17 is used to electrically connect to the second connector 2 electrically connected to the second electronic device, so as to form a signal path between the first electronic device, the first connector 1, the second connector 2, and the second electronic device; the signal path is used to identify the power status between the first electronic device, the first connector 1, the second connector 2, and the second electronic device.

[0036] Compared with the prior art, the first connector 1 provided in the embodiment of the present invention is that every two adjacent LED unit displays in the LED display are connected together through the first connector 1 and the second connector 2. The first AC terminal 15 of the first connector 1 is electrically connected to the second connector 2 to form an AC path connecting the two adjacent LED unit displays. The first DC terminal 16 of the first connector 1 is electrically connected to the second connector 2 to form a DC path connecting the two adjacent LED unit displays. The first signal terminal 17 of the first connector 1 is electrically connected to the second connector 2 to form a signal path connecting the two adjacent LED unit displays. During normal operation, the LED unit display is powered by the AC path. When the AC path fails and is disconnected, the LED unit display is powered by the AC path. The ED unit display screen can be powered by the adjacent LED unit display screen through a DC power path, thereby ensuring the display of the LED unit display screen. Compared with the existing first connector 1 which only has an AC power path, the ED unit display screen can avoid affecting the LED unit display screen connected in series with the first connector 1 when a fault occurs in the AC power path in the first connector 1, thereby preventing the LED unit display screen from experiencing power outages, thereby ensuring the normal display of the LED display screen. At the same time, the power status of the first connector is identified through a signal circuit. When the signal circuit identifies that the AC power path is powered off, the signal circuit sends a relevant indication signal. The user can replace the faulty first connector 1 after the LED display screen is used according to the indication signal, thereby avoiding the user being unable to know the specific conditions of the various components of the LED display screen, thereby facilitating the maintenance of the LED display screen.

[0037] In one implementation of this embodiment, when the signal circuit recognizes that the AC power path is energized, the signal circuit feeds back the signal to the control system of the LED unit display screen, and the control system selects to directly power the LED unit display screen from an external power source through the AC power path based on the signal; when the signal circuit recognizes that the AC power path is disconnected, the signal circuit feeds back the signal to the control system of the LED unit display screen, and the control system selects to power the LED unit display screen from an adjacent LED unit display screen through a DC power path based on the signal, and at the same time, the signal circuit sends a relevant indication signal, and the user can replace the faulty first connector after the LED display screen is used according to the indication signal.

[0038] In one implementation of this embodiment, the signal circuit is used to detect the on / off status of the AC power path. When the signal circuit detects that the AC power path is powered off, the signal circuit sends a related indication signal. The user can replace the faulty first connector after using the LED display screen according to the indication signal.

[0039] It should be noted that the AC power path includes a neutral line path, a live line path and a ground line path, the DC power path includes a DC positive path and a DC negative path, and the signal path includes a first path for detecting and feeding back the on-off state of the neutral line path, a second path for detecting and feeding back the on-off state of the live line path, and a third path for detecting and feeding back the on-off state of the ground line path.

[0040] In this embodiment, the mounting plate 11 is provided with avoidance holes for avoiding the AC path, the DC path, and the signal path.

[0041] Specifically, there are 8 avoidance holes, and each of the neutral line path, live line path, ground line path, DC positive pole path, DC negative pole path, first path, second path and third path corresponds to one avoidance hole.

[0042] In this embodiment, if Figure 2 As shown, an outwardly protruding first annular housing 13 is provided on one end face of the mounting plate 11, which is adjacent to the first electronic device. The first annular housing 13 surrounds the avoidance hole, and the cover 12 is fixed within the first annular housing 13. This helps protect the first AC terminal 15, the first DC terminal 16, and the first signal terminal 17, enhances the waterproof performance of the connection between the first connector 1 and the first electronic device, prevents leakage caused by contact between the first AC terminal 15 and the first DC terminal 16 and other structures, and improves the safety of the first connector 1.

[0043] In this embodiment, if Figure 4As shown, the first AC terminal 15, the first DC terminal 16, and the first signal terminal 17 are fixed to the cover 12 at intervals. This prevents the first AC terminal 15, the first DC terminal 16, and the first signal terminal 17 from contacting each other and causing a malfunction, thereby improving the safety of the first connector 1.

[0044] In this embodiment, if Figure 4 As shown, a first isolation frame 122 is provided on a side of the cover 12 near the first electronic device. The first isolation frame 122 is used to isolate the first AC terminal 15, the first DC terminal 16, and the first signal terminal 17 from each other. This can better protect the first AC terminal 15, the first DC terminal 16, and the first signal terminal 17, prevent interference between them, and improve the safety of the first connector 1.

[0045] Specifically, the first isolation frame 122 isolates the neutral line path, the live line path, the ground line path, the DC positive path, the DC negative path, the first path, the second path, and the third path from each other.

[0046] In this embodiment, if Figure 3 As shown, the cover plate 12 is provided with a buckle 121, and the first annular shell 13 is provided with a locking hole 131. The buckle 121 is locked in the locking hole 131 to fix the cover plate 12 to the first annular shell 13. The structure is simple and convenient for connecting the cover plate 12 and the first annular shell 13.

[0047] In this embodiment, if Figure 2 and Figure 3 As shown, an outwardly protruding second annular housing 14 is provided on one end face of the mounting plate 11 facing away from the first annular housing 13. The second annular housing 14 surrounds the avoidance hole, and a latching groove 141 is provided on the outer surface of the second annular housing 14 for latching with the latching member 217 of the second connector 2. This facilitates the connection between the first connector 1 and the second connector 2, making the connection more stable, while also enhancing the waterproof performance of the connection between the first connector 1 and the second connector 2, and improving the safety of the first connector 1 and the second connector 2.

[0048] In this embodiment, if Figure 2 and Figure 3As shown, multiple guide channels 18 are provided within the second annular housing 14. These guide channels 18 are spaced apart from one another and communicate with the avoidance holes. The AC, DC, and signal pathways are each routed through different guide channels. This facilitates the connection between the first AC terminal 15 and the second AC terminal 214, the first DC terminal 16 and the second DC terminal 215, and the first signal terminal 17 and the second signal terminal 216. This isolates the AC, DC, and signal pathways, preventing interference and improving the safety of the first and second connectors 1 and 2.

[0049] Specifically, the number of the guide channels 18 is set to 8, and the guide channels 18 are arranged in a one-to-one correspondence with the avoidance holes.

[0050] In one embodiment, if Figure 2 As shown, the mounting plate 11 is provided with mounting holes 111, and screws pass through the mounting holes 111 and are fixedly connected to the first electronic device to fix the mounting plate 11 to the first electronic device. This is conducive to fixing the first connector to the first electronic device and is convenient for installation and removal.

[0051] Preferably, the mounting plate 11 is a square plate, and each of the four corners of the mounting plate 11 is provided with a mounting hole 111 .

[0052] Example 2:

[0053] like Figure 2 and Figure 3 As shown, the present invention provides a second connector 2, including a connecting device 21 and a cable 22. The connecting device 21 includes a mounting shell, a second AC terminal 214, a second DC terminal 215, and a second signal terminal 216. The mounting shell is used to connect to the first connector 1 fixed to the first electronic device. The second AC terminal 214, the second DC terminal 215, and the second signal terminal 216 are fixed in the mounting shell. The cable 22 includes an AC wire, a DC wire, and a signal wire.

[0054] The first end of the AC power cord is used to electrically connect to the second electronic device. The second end of the AC power cord is inserted into the mounting housing and electrically connected to the inner end of the second AC terminal 214. The outer end of the second AC terminal 214 is used to electrically connect to the first connector 1 electrically connected to the first electronic device, so that an AC power path is formed between the first electronic device, the first connector 1, the second connector 2, and the second electronic device.

[0055] The first end of the DC power cable is used to electrically connect to the second electronic device. The second end of the DC power cable is inserted into the mounting housing and electrically connected to the inner end of the second DC terminal 215. The outer end of the second DC terminal 215 is used to electrically connect to the first connector 1 electrically connected to the first electronic device, so as to form a DC power path between the first electronic device, the first connector 1, the second connector 2, and the second electronic device.

[0056] The first end of the signal line is used to electrically connect to the second electronic device, one end of the signal line passes through the mounting shell and is electrically connected to the inner end of the second signal terminal 216, and the outer end of the second signal terminal 216 is used to electrically connect to the first connector 1 electrically connected to the first electronic device, so that a signal path is formed between the first electronic device, the first connector 1, the second connector 2, and the second electronic device; the signal path is used to identify the power status between the first electronic device, the first connector 1, the second connector 2, and the second electronic device.

[0057] Compared with the prior art, the second connector 2 provided in the embodiment of the present invention is that every two adjacent LED unit displays in the LED display are connected together through the first connector 1 and the second connector 2. The second AC terminal 214 of the second connector 2 is electrically connected to the first connector 1 to form an AC path connecting the two adjacent LED unit displays. The second DC terminal 215 of the second connector 2 is electrically connected to the first connector 1 to form a DC path connecting the two adjacent LED unit displays. The second signal terminal 216 of the second connector 2 is electrically connected to the first connector 1 to form a signal path connecting the two adjacent LED unit displays. During normal operation, the LED unit display is powered by the AC path. When the AC path fails and is disconnected, the LED unit display is powered by the AC path. The ED unit display screen can be powered by the adjacent LED unit display screen through a DC power path, thereby ensuring the display of the LED unit display screen. Compared with the existing second connector 2 which only has an AC power path, the ED unit display screen can avoid affecting the LED unit display screen connected in series with the second connector 2 when the AC power path in the second connector 2 fails, thereby preventing the LED unit display screen from experiencing power outages, thereby ensuring the normal display of the LED display screen. At the same time, the power status of the second connector is identified through a signal circuit. When the signal circuit identifies that the AC power path is powered off, the signal circuit sends a relevant indication signal. The user can replace the faulty second connector 2 according to the indication signal after the LED display screen is used up, thereby avoiding the user being unable to know the specific conditions of the various components of the LED display screen, thereby facilitating the maintenance of the LED display screen.

[0058] In this embodiment, if Figure 2As shown, the mounting housing includes an outer shell 211, an inner core 212, and a tail sleeve 213. The first end of the outer shell 211 is used to connect to the first connector 1. The second end of the outer shell 211 is fixedly connected to the tail sleeve 213, and a receiving cavity is formed inside the two. The second AC terminal 214, the second DC terminal 215, and the second signal terminal 216 are fixed to the inner core 212, and the inner core 212 is accommodated in the receiving cavity. One end of the cable 22 passes through the tail sleeve 213 and extends into the receiving cavity. The simple structure facilitates the fixing and installation of the second AC terminal 214, the second DC terminal 215, and the second signal terminal 216.

[0059] In this embodiment, if Figure 2 As shown, a second isolation frame 2121 is fixed to one end of the inner core 212 near the tail sleeve 213. The second isolation frame 2121 is used to isolate the inner ends of the second AC terminal 214, the second DC terminal 215, and the second signal terminal 216 from each other. This better protects the second AC terminal 214, the second DC terminal 215, and the second signal terminal 216 from interference, preventing contact and malfunction, thereby improving the electrical safety of the second connector 2.

[0060] In this embodiment, if Figure 2 As shown, the mounting shell further includes a waterproof ring 219 sleeved on the inner core 212. This improves the waterproof performance of the second connector 2, prevents water from penetrating into the second connector 2 and damaging the electronic components in the second connector 2, and improves the electrical safety of the second connector 2.

[0061] In this embodiment, the tail boot 213 is injection molded on the housing 211 to improve the stability and sealing of the connection between the tail boot 213 and the housing 211 and enhance the waterproof performance of the second connector 2.

[0062] In this embodiment, if Figure 2 As shown, the housing 211 further includes a snap-fitting member 217 and a locking member 218. The locking member 218 is used to temporarily snap-fit the snap-fitting member 217 into the slot 141 of the first connector 1, thereby temporarily securing the first connector 1 to the second connector 2. This helps to improve the stability of the connection between the first connector 1 and the second connector 2, and prevents the first connector 1 and the second connector 2 from shaking, causing them to separate and cause a power outage, thereby preventing the normal display of the LED display from being affected.

[0063] In this embodiment, the locking member includes a hinge shaft 2181 and an elastic member 2182. A hinge hole is provided in the middle section of the engaging member 217. The hinge shaft 2181 is disposed within the hinge hole. Both ends of the hinge shaft 2181 are fixed to the housing 211. The engaging member 217 is rotatable about the hinge shaft 2181. The elastic member 2182 is supported by the first end of the engaging member 217 and the housing 211. The elastic member 2182 is configured to maintain a tendency for the second end of the engaging member 217 to move toward the slot 141. The elastic member 2182 is constantly compressed between the first end of the engaging member 217 and the housing 211, so that the elastic member 2182 constantly pushes the first end of the engaging member 217 away from the housing 211, thereby causing the second end of the engaging member 217 to constantly move toward the slot 141. During installation, first plug the second connector 2 into the first connector 1 so that the second annular shell 14 extends into the outer shell 211, and then press the second end of the engaging member 217 downward so that the engaging member 217 is engaged in the slot 141, thereby locking the first connector 1 and the second connector 2; during disassembly, press the first end of the engaging member 217 downward so that the first end of the engaging member 217 compresses the spring downward and moves, so that the second end of the engaging member 217 moves upward and separates from the slot 141, thereby enabling the second connector 2 and the first connector 1 to be disassembled; the structure is simple and easy to install and operate.

[0064] Example 3:

[0065] The difference between the second connector provided in this embodiment and the second connector provided in Example 2 is that the second connector 2 in this embodiment includes two connecting devices 21 .

[0066] The outer end of the second AC terminal 214 of the first connecting device 21 is used to electrically connect to the first connector electrically connected to the first electronic device, and the outer end of the second AC terminal 214 of the second connecting device 21 is used to electrically connect to the first connector 1 electrically connected to the second electronic device. The AC power line electrically connects the inner end of the second AC terminal 214 of the first connecting device 21 and the inner end of the second AC terminal 214 of the second connecting device 21;

[0067] The outer end of the second DC terminal 215 of the first connecting device 21 is used to electrically connect to the first connector 1 electrically connected to the first electronic device, and the outer end of the second DC terminal 215 of the second connecting device 21 is used to electrically connect to the first connector 1 electrically connected to the second electronic device. The DC power line electrically connects the inner end of the second DC terminal 215 of the first connecting device 21 and the inner end of the second DC terminal 215 of the second connecting device 21.

[0068] The outer end of the second signal terminal 216 of the first connecting device 21 is used to electrically connect to the first connector 1 electrically connected to the first electronic device, and the outer end of the second signal terminal 216 of the second connecting device 21 is used to electrically connect to the first connector 1 electrically connected to the second electronic device, and the signal line electrically connects the inner end of the second signal terminal 216 of the first connecting device 21 and the inner end of the second signal terminal 216 of the second connecting device 21.
