[0021] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not drawn to actual scale; for example, the thickness or width of some layers may be exaggerated relative to other layers.

[0022] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.

[0023] like Figures 1-3 As shown, it includes a support frame 1 and an illuminated character 2 installed on one side of the outer wall of the support frame 1. A connection protection component 3 is installed on one side of the outer wall of the illuminated character 2 to protect the cables and the interface of the illuminated character 2, thereby enhancing its electrical safety and structural stability.

[0024] like Figures 1-3As shown, to protect the cable and the interface of the illuminated character 2 and ensure its electrical safety and structural stability, a connector protection component 3 is installed on the outer wall of one side of the illuminated character 2. Specifically, the connector protection component 3 includes a fixing hole 301, which is opened on the outer wall of one side of the illuminated character 2. A fixing cylinder 303 is rotatably connected inside the fixing hole 301. An extrusion plate 304 is provided on the outer wall of the fixing cylinder 303. A waterproof rubber ring 302 is provided on the outer wall of the extrusion plate 304 opposite to the illuminated character 2. A sealing rubber sleeve 305 is slidably connected to the inner wall of the fixing cylinder 303. A rotating cylinder 307 is rotatably connected to the outer wall of the other side of the fixing cylinder 303. A threaded groove is opened on the inner wall of the rotating cylinder 307. A support plate is provided at one end of the inner wall of the rotating cylinder 307. A threaded groove is provided on the outer wall of one side of the support plate. An extrusion cylinder 306 is provided, with its outer wall slidably connected to the inner wall of a fixed cylinder 303. A clamping cylinder is fixedly connected to the outer wall of the other side of the support plate, and a clamping hole 310 is provided on the outer wall of the clamping cylinder. An installation sleeve 308 is rotatably connected to the outer wall of a rotating cylinder 307, and a slope is provided on the inner wall of the installation sleeve 308, with a threaded groove at the bottom end of the slope. An electrical wire 309 is slidably connected to the inner wall of the installation sleeve 308, the rotating cylinder 307, the extrusion cylinder 306, and the sealing sleeve 305. It should be noted that in this embodiment, the fixing pin is first inserted into the mounting hole of the base plate of the support frame 1 to install the illuminated character 2 in the designated position. Then, the sealing sleeve 305 is slidably inserted into the fixed cylinder 303, ensuring that one end of the sealing sleeve 305 is tightly fitted to one side of the inner wall of the fixed cylinder 303. Then, align the fixing cylinder 303 with the rotating fixing hole 301 and rotate it into a certain position until the extrusion plate 304 compresses the waterproof rubber ring 302 to form a seal, effectively preventing water seepage and ensuring the electrical safety of the internal wire 309 and the socket, avoiding dangerous situations such as short circuits or leakage. Next, pass the wire 309 sequentially through the center holes of the mounting sleeve 308, rotating cylinder 307, extrusion cylinder 306, and sealing rubber sleeve 305, and then connect it to the interface of the illuminated character 2 to prevent the wire 309 from loosening or slipping during use. Then, push the extrusion cylinder 306 to slide along the outer wall of the wire 309, inserting it into the fixing cylinder 303. Then rotate the rotating cylinder 307 so that its inner thread groove engages with the thread on the outer wall of the fixing cylinder 303, thereby... The moving extrusion cylinder 306 moves downward, compressing the sealing sleeve 305, causing it to deform and compress the wire 309. This tightly wraps the wire 309 within the sealing sleeve 305, ensuring a stable connection and preventing it from loosening or slipping. The compressed sealing sleeve 305 tightly adheres to the inner wall of the wire 309 and the fixing cylinder 303, forming an effective seal to prevent moisture, dust, and other impurities from entering. This protects the wire 309 and electrical interfaces from corrosion or damage. Through the dual sealing mechanism of the waterproof rubber ring 302 and the sealing sleeve 305, it provides more reliable waterproof and dustproof protection, ensuring the reliability of the equipment in harsh environments. Then, the mounting sleeve 308 is pushed to slide along the wire 309, covering the outer wall of the rotating cylinder 307.Rotating the mounting sleeve 308 causes the threaded groove on its inner wall to engage with the thread on the outer wall of the rotating cylinder 307, thereby moving the mounting sleeve 308 downwards along the inner wall of the rotating cylinder 307. During this movement, the ramp on the inner wall of the mounting sleeve 308 contacts the clamping cylinder. The clamping hole 310 on the outer wall of the clamping cylinder allows it to retract more evenly inwards, further securing the wire 309 and ensuring a stable connection between the wire 309 and the interface. This prevents poor contact or short circuits caused by loosening, thus reducing the risk of electrical faults.

[0025] When protection is required at the interface between the cable and the illuminated sign 2, first insert the fixing pin into the mounting hole of the base plate of the support frame 1 to install the illuminated sign 2 in the designated position. Then, slide the sealing sleeve 305 into the fixing cylinder 303, and then rotate the fixing cylinder 303 to align with the rotating fixing hole 301, thereby causing the extrusion plate 304 to compress the waterproof rubber ring 302 to form a seal, effectively preventing moisture from seeping in. Then, pass the wire 309 through the center hole of the mounting sleeve 308, the rotating cylinder 307, the extrusion cylinder 306, and the sealing sleeve 305 in sequence to connect it to the interface of the illuminated sign 2, preventing the wire 309 from loosening or slipping during use. Finally, push the extrusion cylinder 306 to insert it into the fixing cylinder 303. Then, rotating the rotating cylinder 307 drives the extrusion cylinder 306 downward to extrude the sealing sleeve 305, causing it to deform and compress the wire 309. This ensures that the wire 309 is tightly wrapped inside the sealing sleeve 305, preventing it from loosening or slipping and maintaining a stable connection. Next, rotating the mounting sleeve 308 causes it to move downward along the inner wall of the rotating cylinder 307, so that the slope on the inner wall of the mounting sleeve 308 contacts the clamping cylinder. This allows the clamping cylinder to contract more evenly inward through the clamping hole 310 on the outer wall, further securing the wire 309 and ensuring a stable connection between the wire 309 and the interface. This prevents poor contact or short circuits caused by loosening, thereby reducing the risk of electrical failures.

[0026] In summary, this utility model includes a support frame 1 and an illuminated letter 2 installed on one side of the outer wall of the support frame 1. A protective assembly 3 is installed on one side of the outer wall of the illuminated letter 2 to protect the cables and the interface of the illuminated letter 2, enhancing its electrical safety and structural stability. This utility model achieves a double sealing mechanism through the cooperation of a waterproof rubber ring 302 and a sealing rubber sleeve 305, thus providing more reliable waterproof and dustproof protection. This significantly enhances its electrical safety and structural stability, ensuring stable connection of cables and interfaces, avoiding dangerous situations such as short circuits or leakage caused by loosening or external damage, thereby reducing the risk of electrical failures and protecting the safety of personnel and equipment.
