[0002] In modern industry and daily life, cables serve as vital carriers for power transmission and signal communication, and their connection quality directly impacts the stability and safety of the system. Cable joints are key components for achieving electrical connections between cables or between cables and equipment.

[0003] Traditional cable joint connection and fixing methods are often cumbersome, usually requiring operators to manually tighten bolts, wrap insulating tape, or use special tools for locking. These operations are not only time-consuming and labor-intensive, but also inefficient when faced with a large number of joints to be installed or when working in harsh environments such as narrow spaces or high altitudes.

[0004] Existing cable joint fixing devices often neglect the protection of the external environment after the cable joint is fixed. Especially in outdoor or humid and dusty environments, cable joints exposed for extended periods are susceptible to rainwater erosion, dust accumulation, and even mechanical damage. These external factors can lead to decreased insulation performance and increased contact resistance, resulting in electrical faults such as short circuits and leakage, and in severe cases, even endangering personal safety and equipment operation. Although protective covers or sealing can be added later, these measures often add extra installation steps and costs, and are difficult to integrate seamlessly with the fixing process, failing to fundamentally address the integrated need for rapid fixing and immediate protection.

[0005] Therefore, this utility model proposes a quick-fixing device for cable joints to address the shortcomings of existing technologies. Summary of the Invention

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Reference Figures 1-5 This utility model provides an embodiment of a cable connector quick-fixing device, including a support frame 1. The support frame 1 has a fixing groove 308 inside for accommodating the cable connector. A fixing component 3 is located above the support frame 1, and a protective component 2 is rotatably connected to the outside of the support frame 1. The fixing component 3 includes a fixing block 306, which is slidably disposed within the support frame 1 and located above the fixing groove 308. The lower end of a fixing post 305 is fixedly connected to the fixing block 306, a fixing plate 302 is fixedly connected to the upper end of the fixing post 305, and a pull ring 301 is fixedly connected to the fixing plate 302. The upper end of shaft 303 is fixedly connected to fixed plate 302, the upper end of tension spring 304 is connected to the lower end of connecting shaft 303, and the lower end of tension spring 304 is fixedly connected to support frame 1. The protective component 2 includes support plate 205, which is fixedly connected to the outer wall of support frame 1. Rotating shaft 203 is rotatably connected to support plate 205, rotating plate 201 is fixedly connected to rotating shaft 203, protective shell 202 is fixedly connected to rotating plate 201, and torsion spring 204 is sleeved on rotating shaft 203. One end of torsion spring 204 is fixed to support plate 205, and the other end of torsion spring 204 is fixed to rotating shaft 203. The inner wall of the support frame 1 is provided with a vertical limiting groove 307. The side of the fixing block 306 has a structure that is adapted to the limiting groove 307. In the assembled state, the side of the fixing block 306 slides in the limiting groove 307. This guide groove and slider cooperation structure ensures that the fixing block 306 moves stably in the vertical direction and avoids jamming or deflection. In addition, the bottom surface of the fixing block 306 is provided with an arc-shaped pressing groove for pressing the cable joint. When the fixing block 306 is pressed down, it fits the shape of the cable joint and achieves a more secure pressing. The assembly relationship of each component in the fixing assembly 3 is as follows: the connecting shaft 303 and the fixing column 305 are both fixedly connected to the bottom surface of the fixing plate 302, and the pull ring 301 is fixedly connected to the top surface of the fixing plate 302. To improve the waterproof sealing performance of the device, please refer to Figure 4 A waterproof ring 206 is fixedly connected to the inner wall of the protective shell 202. The waterproof ring 206 is made of elastic sealing material. In order to enhance the installation stability of the protective component 2, there are two support plates 205. The two support plates 205 are fixed to the outer wall of the support frame 1 in parallel and spaced apart. The rotating shaft 203 is rotatably connected between the two support plates 205.

[0015] Working principle: Before fixing the cable connector, the operator pulls the protective shell 202 outward through the protective component 2. The rotating plate 201 is fixedly connected to the rotating shaft 203, which is rotatably connected to the support plate 205. The support plate 205 is fixedly connected to the outer wall of the support frame 1. When the rotating plate 201 is pulled outward, it will cause the rotating shaft 203 to flip outward on the support plate 205. The protective shell 202 is fixedly connected to the rotating plate 201, and it will flip outward together with the rotating plate 201, allowing the cable connector to enter the support frame 1. The torsion spring 204 is sleeved on the rotating shaft 203. One end of the torsion spring 204 is fixed to the support plate 205, and the other end is fixed to the rotating shaft 203. When the rotating shaft 203 rotates within the support plate 205, it will act on the torsion spring 204. After the protective shell 202 is opened, the operator pulls the pull ring 301 upwards. The pull ring 301 is fixedly connected to the fixing plate 302. When the fixing plate 302 is pulled upwards, it will cause the connecting shaft 303 and the fixing post 305 to move upwards together. The lower end of the fixing post 305 is fixedly connected to the fixing block 306. The fixing block 306 will move upwards together with the fixing post 305. After the fixing block 306 moves upwards out of the fixing groove 308, the cable connector is placed from the fixing groove 308 into the support frame 1 and connected. The upper end of the connecting shaft 303 is fixedly connected to the fixing plate 302. The upper end of the tension spring 304 is connected to the lower end of the connecting shaft 303. The lower end of the tension spring 304 is fixedly connected to the support frame 1. When the connecting shaft 303 moves upwards, the tension spring 304 will be pulled upwards along with the connecting shaft 303. After the cable connector is placed and connected, the operator releases the pull ring 301. At this time, the tension spring 304 pulls the connecting shaft 303, causing the fixing plate 302, the connecting shaft 303, the fixing post 305, and the fixing block 306 on the fixing post 305 to return to their original positions. The fixing block 306 moves down to fix the cable connector and prevent it from loosening. The inner wall of the support frame 1 has a vertical limiting groove 307, and the side of the fixing block 306 slides into the limiting groove 307. This engagement limits the cable connector when the fixing block 306 moves down, ensuring a more secure fixation of the cable connector. After the cable connector is secured, the operator releases the rotating plate 201. The torsion spring 204, due to its elasticity, causes the rotating shaft 203 to rotate the rotating plate 201 and the protective shell 202 back on the support plate 205. The protective shell 202 wraps around the cable, and at the same time, the waterproof ring 206 fixedly connected to the inner wall of the protective shell 202 prevents rainwater from entering the device from the cable and damaging the cable connector.
