[0028] By applying the technical solution of this embodiment, the control box assembly includes: a box body 10, a control board 20, a plug 30 and a plug assembly 40. Since the female header 41 is plugged with the pin header 42, the external signal is transferred to the plug assembly 40 through the plug 30, and the signal can be directly transmitted to the control board 20 through the transfer of the plug assembly 40, which saves the network cable in the related art, and the assembly process is simple and convenient, and the installation operation is simple, which can solve the problem of using the signal connector in the related art to transfer the signal to the control board through the network cable for multiple times, making the assembly process complicated.

[0029] Of course, in an embodiment not shown in the figure, the pin header is connected to the control board, and the female header is connected to the plug.

[0030] like Figures 1 to 3 As shown, the control board 20 includes an adapter board 21 and a receiving card 22 connected to the adapter board 21, and the female header 41 is connected to the adapter board 21. In this way, the female header 41 and the pin header 42 in the box body 10 are directly plugged and matched to transmit signals, which can effectively save the cost of network cables.

[0031] like Figures 1 to 3 As shown, for easy installation, the transmission pins 421 of the pin header 42 are perpendicular to the conductive posts of the plug 30 . In addition, the portion of the pin header 42 facing the female header 41 protrudes from the outer side of the plug 30 .

[0032] like Figures 1 to 3 As shown, the transmission tube 411 of the female header 41 is perpendicular to the board surface of the control board 20, so that the transmission pin 421 of the pin header 42 is directly plugged into the transmission tube 411 of the female header 41. This direct plug-in transmission makes the signal transmission more stable, saves operating space, and is simple to install.

[0033] Specifically, the pin header 42 includes a shell and a plurality of transmission pins 421 disposed in the shell, and the female header 41 includes a female socket and a plurality of transmission cylinders 411 disposed on the female socket. The plurality of transmission pins 421 are plugged and matched with the plurality of transmission cylinders 411 in a one-to-one correspondence.

[0034] like Figures 1 to 3 As shown, for easy installation and operation, the box body 10 includes a box bottom wall 11 and a box surrounding wall 12 arranged around the edge of the box bottom wall 11 , the plug 30 is inserted into the box surrounding wall 12 , and the pin header 42 is connected to the plug 30 .

[0035] like Figures 1 to 3 As shown, the box surrounding wall 12 includes two side walls 121 arranged opposite to each other, the distance between the ends of the two side walls 121 is greater than the distance between the middle parts of the two side walls 121, and the connector assembly 40 is located between the ends of the two side walls 121. In this way, the space between the ends of the two side walls 121 is greater than the space between the middle parts of the two side walls 121, which facilitates the installation of the connector assembly 40 between the ends of the two side walls 121.

[0036] like Figures 1 to 3 As shown, the control board 20 includes an adapter board 21 and a receiving card 22 connected to the adapter board 21. The adapter board 21 includes a board body 211 and a protrusion 212 arranged on at least one side of the board body 211, the end of the protrusion 212 facing the side wall 121 protrudes from the side of the board body 211, and the female connector 41 is connected to the protrusion 212. In this way, the external signal is transferred to the pin header 42 through the plug, and then the signal can be directly transmitted to the adapter board 21 through the transfer of the female connector 41 that is plugged with the pin header 42, and then can be transmitted to the receiving card 22, which effectively saves the network cable in the related art.

[0037] Specifically, two female headers 41 and two female headers 42 are provided correspondingly. To facilitate installation, two protrusions 212 are provided on both sides of the board body 211 .

[0038] like Figures 1 to 3 As shown, the plug 30 is an aviation plug, and the number of transmission pins 421 of the pin row 42 is 8. Signal transmission adopts the method of direct insertion of the 8 transmission pins 421 and the transmission tube 411, and the signal is more stable.

[0039] Of course, in an embodiment not shown in the figure, the number of transmission pins of the pin row is 4 or 12 or 4N, where N is a positive integer greater than 3.

[0040] like Figures 1 to 3 As shown, in order to supply power to the components on the control board 20 , the control box assembly further includes a power supply unit 50 disposed in the box body 10 , and the power supply unit 50 is plug-connected to the control board 20 .

[0041] Specifically, the power supply component 50 is provided with a power female header, and the control board 20 is also provided with a power pin header that is plugged with the power female header. In this way, the power supply component 50 supplies power to the control board through the plugging of the power female header and the power pin header.

[0042] The present application also provides an LED display screen, which includes a box body, a control box assembly arranged at the rear side of the box body, and a display module arranged at the front side of the box body, wherein the control box assembly is the above-mentioned control box assembly, and the control board 20 of the control box assembly is connected to the display module. Since the above-mentioned control box assembly can solve the problem in the related art that the signal connector is used to transmit the signal to the control board through multiple network cable transfers, which makes the assembly process cumbersome, the LED display screen having the control box assembly can solve the same technical problem.

[0043] In this embodiment, the box body 10 is detachably mounted on the rear side of the box body. The locking structure is arranged on the box body, and the locking structure includes a mounting plate, a locking plate and a positioning member. The mounting plate is arranged on the box body and forms a mounting interlayer with the box body, the locking plate is movably arranged in the mounting interlayer and has a evasion position and a locking position, and the positioning member is arranged between the mounting plate and the locking plate. When the locking plate is located in the mounting interlayer to be in the evasion position, the box body 10 can be removed from the rear side of the box body, and when the locking plate extends out of the mounting interlayer and locks with the box body 10 to be in the locking position, the box body 10 is locked at the rear side of the box body. Among them, the locking plate can be kept in the evasion position or the locking position by the positioning member. In this way, the evasion position and the locking position of the above-mentioned locking plate make it quick and simple to remove and install the box body 10 from the box body, and can be operated with one hand, which is convenient to operate. In addition, the locking plate can be kept in the evasion position or the locking position by the positioning member. In this way, through the positioning of the positioning piece, the locking plate can be reliably maintained in the avoidance position or the locking position, thereby reducing the possibility that the locking plate is easily loosened when subjected to vibration.

[0044] In this embodiment, the positioning member includes a first positioning hole, a second positioning hole and a positioning column. The second positioning hole is closer to the box body 10 than the first positioning hole. The first positioning hole and the second positioning hole are both arranged on the mounting plate. The positioning column is arranged on the locking plate. When the positioning column is positioned and matched with the first positioning hole, the locking plate is kept in the avoidance position. When the positioning column is positioned and matched with the second positioning hole, the locking plate is kept in the locking position. In the process of the locking plate moving from the locking position to the avoidance position, when the thrust of the operator pushing the locking plate is greater than the positioning force between the positioning column and the second positioning hole, the positioning column slides out of the second positioning hole until the positioning column slides into the first positioning hole and is positioned and matched with the first positioning hole. At this time, since the positioning column is hindered by the hole wall of the first positioning hole, that is, the thrust of pushing the locking plate is less than the positioning force between the positioning column and the first positioning hole, the operator stops pushing the locking plate. Since the positioning force between the positioning column and the first positioning hole is large, so that the locking plate is kept in the avoidance position, the box body 10 can be quickly and easily removed from the rear side of the box body. On the contrary, the box body 10 can be reliably locked on the rear side of the box body so that the locking plate is kept in the locking position. In this way, the positioning column and the first positioning hole and the second positioning hole are respectively positioned and matched with each other in a simple structure, with reliable positioning and easy processing.

[0045] In this embodiment, the locking structure further includes an elastic member disposed between the closed end and the locking plate, and the elastic member applies an elastic force to the locking plate so that the locking plate is in an evasive position or a locked position. When the locking plate is in the evasive position, the box body 10 can be removed from the box body, the elastic member is compressed, and the positioning column is positioned and matched with the first positioning hole. When the box body 10 is to be locked, the locking plate is moved, and the locking plate easily slides out of the first positioning hole and slides into the second positioning hole under the action of the spring. The box body 10 is locked by the locking plate, and under the action of the elastic force of the elastic member, the locking plate is not easy to rebound and unlock, which plays a safety role. The elastic member is preferably a compression spring.

[0046] In this embodiment, the positioning column is a telescopic column, and the telescopic direction of the telescopic column is perpendicular to the moving direction of the locking plate. When the locking plate switches between the locking position and the avoidance position, the telescopic column can automatically retract to avoid the hole wall of the first positioning hole and the hole wall of the second positioning hole. When the positioning column moves to the first positioning hole, the telescopic column can automatically extend, and the positioning column can be positioned with the first positioning hole. When the positioning column moves to the second positioning hole, the telescopic column can automatically extend, and the positioning column can be positioned with the second positioning hole. Specifically, the telescopic column includes a spring and a marble that abuts against the spring. The marble is positioned with the first positioning hole or the second positioning hole.
