[0002] LED screen controller, also known as LED asynchronous control system or LED display screen control card, is the core component of LED graphic display screen. It is responsible for receiving the picture display information from the computer serial port, placing it into the frame memory, and generating the serial display data and scanning control timing required by the LED display screen according to the partition drive mode. By receiving, converting and processing signals, the LED screen controller can transmit images, text, video and other content to the LED display screen and achieve high-quality and accurate playback effects.

[0003] The socket of the LED screen controller is a key part for connecting various cables and devices, so it is crucial to keep it clean and prevent dust from entering. The accumulation of dust may cause poor contact, unstable signal transmission, and even damage the electronic components inside the controller. Prevent dust accumulation in the socket of the LED screen controller and extend the service life of the controller.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] like Figures 1 to 6 As shown, a LED screen controller with a socket protection function includes a body 1, a socket 2 is provided on one side of the body 1, a DVI cable port 3 is provided on one side of the socket 2, and a network cable port 4 is provided on one side of the DVI cable port 3, a dust shield assembly 5 is installed on the surface of the socket 2, and the dust shield assembly 5 is rotatably connected to one side of the body 1, a magnetic sticker assembly 6 is installed on the surface of the DVI cable port 3, and the magnetic sticker assembly 6 is bonded to the surface of one side of the body 1, a rubber blocking block 8 is provided in the network cable port 4, and the rubber blocking block 8 and the network cable port 4 are inserted and connected.

[0025] like Figure 1 As shown, the LED screen controller with a socket protection function in the utility model is similar to the existing LED screen controller structure, such as the LED screen controller disclosed in the patent publication number CN208400091U. The main improvement of the utility model is that the LED screen controller can improve the signal transmission quality, such as Figures 1 to 6As shown, when the LED screen controller with a socket protection function in the utility model is in use, the dust is blocked on the outside of the socket 2 by using the dust shield assembly 5. The dust shield assembly 5 uses a reset spring 503 to allow the baffle 501 to rebound quickly after the power cord in the socket 2 is unplugged. The baffle 501 blocks the opening of the socket 2 to prevent dust from entering the socket 2. The magnetic sticker assembly 6 is magnetically adsorbed on the surface of the body 1 to block the DVI cable port 3. The DVI cable port 3 is a prototype cable port. Compared with the socket 2, the power cord is inserted into the socket for a long time. 2, the power cord end makes the socket 2 waterproof, the DVI cable port 3 has no waterproof effect, the connection method of the magnetic patch has a certain waterproof function, which can effectively prevent moisture and dust from entering the inside of the device and ensure the normal use of the electronic equipment. There are many network cable ports 4, and some of them are not used frequently. The rubber block 8 has good elasticity and durability, can fit tightly against the network cable port 4, and is not easy to fall off or deform; this means that even if the network cable port 4 is not often used, the rubber block 8 can maintain its effect for a long time, providing users with lasting protection.

[0026] like Figure 3 to Figure 4 As shown, the dust baffle assembly 5 includes a baffle 501, a fixing rod 502 and a return spring 503. The fixing rod 502 is rotatably connected to the inner wall of the socket 2, and the return spring 503 is sleeved on the outer side of the fixing rod 502. Both ends of the return spring 503 are fixedly connected to the inner wall of the socket 2, the outer side of the return spring 503 is fixedly connected to the outer side of the fixing rod 502, and the baffle 501 is fixedly connected to the outer side of the fixing rod 502.

[0027] Specifically, by setting up the return spring 503, the baffle 501 that has been pulled away from the socket 2 can be pulled back to the opening of the socket 2. When the socket 2 is not in use, the baffle 501 always keeps covering the opening of the socket 2, and after the power cord is unplugged, the socket 2 can be quickly blocked to prevent dust and dirt from entering the inside of the socket 2.

[0028] like Figure 3 to Figure 4 As shown, the inner walls of the socket 2 are provided with card slots 201 , one end of the card slot 201 is communicated with the outside, and the two side walls of the card slot 201 are fitted and connected with the two sides of the baffle 501 .

[0029] Specifically, through this setting, the baffle 501 is affected by the tension of the return spring 503 and is pulled toward the socket 2. The slot 201 allows the baffle 501 to be fixed on the surface of the socket 2, avoiding excessive pulling of the baffle 501, which would cause a gap when it fits with the opening of the socket 2 and cause dust to enter.

[0030] like Figures 5 and 6As shown, the magnetic sticker assembly 6 includes a connecting plate 601, a flip plate 604 and a magnetic iron sheet 7. An open channel 602 is provided on the surface of the connecting plate 601. A fixed column 603 is installed between the two side walls of the open channel 602. A rotating ear 605 is rotatably connected to the outer side of the fixed column 603. A flip plate 604 is installed at the bottom of the rotating ear 605. A groove 606 is provided on the back side of the connecting plate 601. The magnetic iron sheet 7 is installed in the groove 606. A paddle 9 is installed on the surface of the flip plate 604.

[0031] Specifically, through this arrangement, when a DVI cable needs to be connected, the flip plate 604 can be turned upward and the DVI cable can be inserted into the cable port to use the device. The magnetic sticker component 6 provides waterproof and dustproof functions while having anti-scratch functions, which can protect the exposed connector of the DVI cable port 3.

[0032] like Figure 6 As shown, the height of the magnetic iron sheet 7 is lower than the depth of the groove 606 .

[0033] Specifically, when the magnetic iron sheet 7 is adsorbed on the outside of the body 1, the connection plate 601 and the body 1 are tightly connected to prevent dust, water, etc. from entering the DVI port 3, thereby preventing poor contact of the DVI port 3 due to dust accumulation.

[0034] like Figures 5 and 6 As shown, the outer side of the flap 604 and the inner wall of the open channel 602 are closely connected.

[0035] Specifically, this arrangement improves the flexibility of the magnetic patch assembly 6, so that the flip plate 604 can be opened to insert the DVI cable into the port to use the device, and the flip plate 604 and the open channel 602 can be closed at any time to keep the DVI port 3 clean and dry.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
