Abstract
Description
Technical Field
[0001] The utility model relates to the field of LED display screens, and specifically to a waterproof connector for an LED display screen. Background Technique
[0002] DVI connectors play an indispensable role in the field of LED display screens. With its high-quality digital signal transmission ability, it ensures the clarity and color fidelity of image display, while supporting high bandwidth to meet the data transmission requirements of high-definition LED display screens. The plug-and-play function and good system compatibility of DVI bring a convenient user experience. Especially in professional applications such as advertising and exhibitions, DVI connectors ensure the stable transmission and high-quality display of video signals, and are key components to improve the performance of LED display screens and enhance the user experience.
[0003] The existing DVI connection cable is an important data connection device for LED display screens. During the process of plugging and using, if it is used outdoors, due to the relatively complex external environment, it may encounter rainy, snowy, humid and other weather conditions, resulting in some moisture or water vapor entering the connection between the DVI connection cable and the LED display screen, leading to poor data transmission and affecting the service life of the connection cable. Content of the Utility Model
[0004] Based on this, the purpose of the utility model is to provide a waterproof connector for an LED display screen to solve the technical problem that the existing DVI connection cable has poor waterproof performance in the face of rainy and humid environments.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A waterproof connector for an LED display screen includes a connector main body and a female head main body. A plug main body is arranged at the top of the connector main body, a male head main body is arranged at the top of the plug main body, and a protection mechanism is arranged outside the female head main body. The protection mechanism includes a limit frame, a sealing ring is arranged inside the limit frame, a clamping groove is arranged inside the sealing ring, and a clamping block is arranged outside the male head main body.
[0006] By adopting the above technical solution, through the tight docking of the clamping block and the clamping groove, a stable connection is achieved between the male head main body and the female head main body. At the same time, during the clamping process, the rubber sealing ring deforms under the pressing of the clamping block, effectively filling the gap between the limit frame and the male head main body, not only enhancing the overall structural stability of the DVI connector, but also achieving efficient sealing of the connection end of the connector.
[0007] Furthermore, the clamping block is clamped with the sealing ring through the clamping groove, and the cross-section of the clamping block is in a wedge-shaped structure.
[0008] By adopting the above technical solution, the stability of the connection of the connector is enhanced. The wedge-shaped structure of the clamping block enables the male head body to enter the female head body more smoothly during the insertion process and ensures that the clamping block can accurately dock with the clamping groove.
[0009] Furthermore, the material of the sealing ring is rubber, and the sealing ring is adhesively fixed to the limiting frame with glue.
[0010] By adopting the above technical solution, the rubber material has good elasticity and water resistance, which enables the sealing ring to deform appropriately when pressed by the clamping block, tightly fill the gap, and thus effectively block external moisture.
[0011] Furthermore, rotating mechanisms are provided on both sides of the plug body, and the rotating mechanism includes a screw rod.
[0012] By adopting the above technical solution, the fastening degree of the connector can be conveniently adjusted to ensure a stable connection between the male head body and the female head body, providing a flexible connection method that enables the operator to adjust the tightness of the connection according to actual needs.
[0013] Furthermore, a first rotating block and a second rotating block are provided at the bottom end of the screw rod, and the first rotating block is rotatably connected to the second rotating block through a rotating rod.
[0014] By adopting the above technical solution, by turning the first rotating block and the second rotating block, the screw rod can be driven to rotate, thereby realizing the threaded connection between the screw rod and the nut block. This operation method is simple and efficient and can quickly complete the fastening work of the connector.
[0015] Furthermore, a plurality of anti-slip teeth are provided on the outer sides of the first rotating block and the second rotating block, and are arranged in an equidistant annular pattern.
[0016] By adopting the above technical solution, the plurality of anti-slip teeth can effectively increase the friction force, enabling the operator to have a better grip feeling during the turning process, thereby preventing the hand from slipping. This not only improves the safety of the operation but also ensures that the operator can accurately and efficiently complete the turning action.
[0017] Furthermore, nut blocks are provided on both sides of the female head body, and the screw rod is threadedly connected to the nut blocks.
[0018] By adopting the above technical solution, the threaded connection between the nut block and the screw rod provides a reliable fastening mechanism for the connector. This connection method ensures the stable docking between the male head body and the female head body, thereby maintaining the stability of data transmission or power transmission.
[0019] In summary, the present utility model mainly has the following beneficial effects:
[0020] 1. Through the protection mechanism, the DVI connector achieves efficient sealing and safe waterproofing through the interaction of the clamping block, the clamping groove, and the sealing ring. First, the clamping block is clamped and limited with the sealing ring through the clamping groove, ensuring the stability of the connection. At the same time, this clamping causes the rubber sealing ring to deform, and the deformed sealing ring effectively fills the gap between the limiting frame and the male head body, not only enhancing the structural strength of the connector but also achieving efficient sealing of the connection end of the DVI connector, significantly improving its safe waterproofing performance and making it more adaptable to complex and changeable environmental conditions.
[0021] 2. By turning the first rotating block and the second rotating block, the present utility model can effectively drive the screw to rotate, thereby realizing the threaded connection between the screw and the nut block. This connection method is stable and adjustable, capable of meeting different fastening requirements. At the same time, during the turning process, the setting of the rotating rod enables the first rotating block and the second rotating block to rotate at a certain angle, which provides a convenient force application point for the operator, making the rotation of the screw easier and more labor-saving. It not only improves the stability of the connection but also significantly enhances the convenience of operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following is an illustration of the embodiments of the present utility model based on its overall structure.
[0031] Embodiment 1:
[0032] A waterproof connector for an LED display screen, as Figures 1 - 4 shown, includes a connector body 1 and a female head body 4. A plug body 2 is provided at the top of the connector body 1, a male head body 3 is provided at the top of the plug body 2, and a protection mechanism 6 is provided outside the female head body 4. The protection mechanism 6 includes a limit frame 601, a sealing ring 602 is provided inside the limit frame 601, a clamping groove 604 is opened inside the sealing ring 602, a clamping block 603 is provided outside the male head body 3, and the clamping block 603 is in close butt joint with the clamping groove 604, realizing a firm connection between the male head body 3 and the female head body 4. At the same time, during the clamping process, the sealing ring 602 made of rubber deforms under the pressing of the clamping block 603, effectively filling the gap between the limit frame 601 and the male head body 3, not only enhancing the overall structural stability of the DVI connector, but also realizing the efficient sealing of the connection end of the connector. Thus, the waterproof performance of the connector is significantly improved. Even in a humid or water-vapor-containing environment, the connector can maintain a good working state, ensuring the safety and reliability of the device connection.
[0033] Refer to Figure 4, the snap block 603 is snap-connected to the sealing ring 602 through the snap groove 604. The cross-section of the snap block 603 is a wedge-shaped structure, which enhances the stability of the connector connection. The wedge-shaped structure of the snap block 603 enables the male head body 3 to enter the female head body 4 more smoothly during the insertion process and ensures that the snap block 603 can accurately dock with the snap groove 604. At the same time, the wedge-shaped structure also causes the snap block 603 to gradually compress the sealing ring 602 during the insertion process, thereby ensuring that the sealing ring 602 can closely fit around the connector, further improving the waterproof performance. This not only simplifies the connection process but also enhances the connection stability and waterproof effect.
[0034] Refer to Figure 3 , Figure 4 , the material of the sealing ring 602 is rubber. The sealing ring 602 and the limiting frame 601 are adhesively fixed by glue. The rubber material has good elasticity and water resistance, which enables the sealing ring to deform appropriately when pressed by the snap block 603 and tightly fill the gap, thereby effectively blocking external moisture. At the same time, the sealing ring 602 and the limiting frame 601 are adhesively fixed by glue, ensuring the stability of the position of the sealing ring 602 and the durability of the sealing performance. This fixing method can prevent the sealing ring 602 from shifting or falling off during use, further enhancing the waterproof effect of the connector.
[0035] Embodiment 2:
[0036] Refer to Figure 1 , Figure 2 , rotating mechanisms 5 are provided on both sides of the plug body 2. The rotating mechanism 5 includes a screw 501, which can conveniently adjust the tightening degree of the connector, ensure the stable connection between the male head body 3 and the female head body 4, provide a flexible connection method, enable the operator to adjust the tightness of the connection according to actual needs. At the same time, the presence of the screw 501 also enhances the structural strength of the connector, providing additional support and stability for the connector. This adjustable and stable setting enables the connector to adapt to more different application scenarios, improving its practicality and reliability.
[0037] Refer to Figure 1 , Figure 2, at the bottom end of the screw rod 501, a first rotating block 502 and a second rotating block 503 are provided. The first rotating block 502 is rotationally connected to the second rotating block 503 through a rotating rod 504. By turning the first rotating block 502 and the second rotating block 503, the screw rod 501 can be driven to rotate, thereby realizing the threaded connection between the screw rod 501 and the nut block 7. This operation method is simple and efficient, and can quickly complete the fastening work of the connector. At the same time, the rotating rod 504 connects the first rotating block 502 and the second rotating block 503, and can make the second rotating block 503 rotate flexibly at a certain angle during the turning process, providing a convenient force application point for the operator. This not only reduces the operation difficulty, but also improves the efficiency of the threaded connection between the screw rod 501 and the nut block 7, making the entire connection process smoother and more efficient.
[0038] Refer to Figure 1 , Figure 2 , on the outer sides of the first rotating block 502 and the second rotating block 503, a plurality of anti-slip teeth 505 are provided, and they are arranged in an equidistant annular pattern. The plurality of anti-slip teeth 505 can effectively increase the friction force, enabling the operator to have a better grip feeling during the turning process, thereby preventing the hand from slipping. This not only improves the operation safety, but also ensures that the operator can accurately and efficiently complete the turning action. At the same time, the equidistant annular arrangement of the anti-slip teeth 505 makes the grip force distribution more uniform, further enhancing the anti-slip effect and also improving the operator's operation experience.
[0039] Refer to Figure 1 , Figure 2 , Figure 3 , on both sides of the female head body 4, nut blocks 7 are provided. The screw rod 501 is threadedly connected to the nut blocks 7. The threaded connection between the nut blocks 7 and the screw rod 501 provides a reliable fastening mechanism for the connector. This connection method ensures the stable docking between the male head body 3 and the female head body 4, thereby maintaining the stability of data transmission or power transmission. At the same time, the flexibility of the threaded connection enables the operator to adjust the tightness of the connection as needed, preventing signal instability caused by too loose connection and avoiding damage that may be caused by too tight connection. It not only guarantees the connection safety, but also extends the service life of the connector.
[0040] The implementation principle of the present utility model is as follows: When it is necessary to plug in the DVI connection cable, first, make the male head body 3 and the female head body 4 face each other, and then plug the male head body 3 and the female head body 4. As the plugging progresses, the clamping block 603 on the outer side of the male head body 3 gradually presses against the inner side of the sealing ring 602. Since the material of the sealing ring 602 is rubber, the sealing ring 602 deforms accordingly until the clamping block 603 is clamped with the clamping groove 604 on the inner side of the sealing ring 602. Then, turn the first rotating block 502 and the second rotating block 503 to drive the screw rod 501 to rotate, causing the screw rod 501 to be threadedly connected with the nut block 7. During the turning process, the first rotating block 502 and the second rotating block 503 can be adjusted through the rotating rod 504, causing the second rotating block 503 to rotate at a certain angle. At this time, a more convenient force application point for rotating the screw rod 501 can be provided for the operator, improving the convenience of the threaded connection between the screw rod 501 and the nut block 7, and completing the connection operation of the DVI connector. During this connection process, through the clamping and limiting of the clamping block 603 with the clamping groove 604 and the sealing ring 602, the rubber sealing ring 602 deforms, so that the sealing ring 602 fills the gap between the limiting frame 601 and the male head body 3, thereby realizing the efficient sealing of the connection end of the DVI connector and improving its safety and waterproof performance.
[0041] Parts not involved in the present utility model are the same as or can be implemented by using the prior art, and will not be elaborated here too much.
