[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1-5 A prefabricated terminal cable connector includes a cable protection sleeve 1. The top of the cable protection sleeve 1 is detachably connected to multiple sets of first umbrella skirts 2. The top of the first umbrella skirts 2 is fixedly connected to a sleeve 3. The top of one of the first umbrella skirts 2 is detachably connected to a second umbrella skirt 15 through the sleeve 3. The bottom of both the first umbrella skirt 2 and the second umbrella skirt 15 is fixedly connected to a threaded ring 9. The top of the second umbrella skirt 15 is fixedly connected to a limit ring 4. The limit ring 4 has a terminal 5 inside. The terminal 5 is sleeved on the outside of a sleeve 6. A sealing ring 7 is slidably connected to the lower part of the inside of the sleeve 6. Clamping plates 8 are symmetrically arranged on the upper part of the inside of the sleeve 6. A linkage component is arranged inside the sleeve 6.

[0022] Specifically, the linkage assembly includes a slide rod 10 and a linkage unit. The slide rod 10 is symmetrically slidably connected to both sides of the inside of the sleeve 6. Two clamping plates 8 are respectively fixedly connected to one end of each set of slide rods 10. The inside of the sleeve 6 is threaded with self-locking screws 11. One end of the self-locking screws 11 extends into the inside of the sleeve 6 and is fixedly connected to the corresponding clamping plate 8. The sealing ring 7 can be pressed down through the linkage unit. The linkage unit includes an inclined block 12. The inclined block 12 is slidably connected to the upper part of the inner wall of the sleeve 6. The top of the sealing ring 7 is fixedly connected with limit rods 13 at equal intervals. The inclined block 12 is slidably connected to the top of multiple limit rods 13. A spring 14 is provided outside the limit rods 13 and between the sealing ring 7 and the inclined block 12.

[0023] Using the above technical solution, firstly, the terminal 5 is installed, then the sleeve 6 is placed over the outside of the terminal 5 until the bottom of the sleeve 6 contacts the top of the limiting ring 4. Then, the self-locking screws 11 on both sides are manually rotated. Through the threaded connection, the corresponding clamping plate 8 is driven to move into the sleeve 6 under the limitation of the slide rod 10. During the inward movement of the clamping plate 8, the inclined surface of the inclined block 12 can be pushed, pushing the inclined block 12 downward. Thus, the sliding of the inclined block 12 outside the limiting rod 13 applies downward pressure to the spring 14 and the sealing ring 7. Once the clamping plates 8 on both sides are fully clamped to the terminal 5, the sleeve 6 is installed and fixed through the mutual cooperation between the terminal 5 and the clamping plates 8. This prevents the sleeve 6 from loosening after prolonged use, which could lead to the loosening of the sealing ring 7. Furthermore, the downward pressure from the inclined block 12 and the spring 14 ensures that the sealing ring 7 seals the connection between the terminal 5 and the limiting ring 4. Additionally, the spring 14 adjusts the pressure of the sealing ring 7 according to its own stress, thus ensuring that the sealing ring 7 always maintains a tight fit at the connection between the terminal 5 and the limiting ring 4, effectively preventing the terminal from... Prolonged use and exposure to rain and sun can cause the sealing ring 7 to soften and deform, leading to a failure of the seal at the connection between the terminal 5 and the limiting ring 4. This can result in rainwater leakage and potential discharge breakdown. This device effectively improves safety and extends its lifespan. The device uses the clamping plate 8 to hold the installed terminal 5, thus securing the sleeve 6 and preventing loosening of the sleeve 6 and sealing ring 7 after prolonged use. This enhances stability. Furthermore, the inclined block 12 and the lower spring 14... The pressure allows the sealing ring 7 to seal the connection between the terminal 5 and the limiting ring 4. In addition, the spring 14 adjusts the pressure of the sealing ring 7 according to its own stress, thereby ensuring that the sealing ring 7 always fits tightly against the connection between the terminal 5 and the limiting ring 4. This effectively prevents the sealing ring 7 from softening and deforming due to prolonged use and exposure to rain and sun, which could lead to failure of the seal at the connection between the terminal 5 and the limiting ring 4. This would prevent rainwater leakage on rainy days and cause discharge breakdown, thus effectively improving the safety and service life of the device.

[0024] Specifically, the threaded ring 9 has an external thread on its outside and the sleeve 3 has an internal thread on its inside. The first umbrella skirt 2 is provided in multiple sets, and each first umbrella skirt 2 is threadedly connected to the sleeve 3 at the top of the first umbrella skirt 2 below it through the threaded ring 9 at its bottom. The second umbrella skirt 15 is threadedly connected to the sleeve 3 at the top of the first umbrella skirt 2 below it through the threaded ring 9 at its bottom.

[0025] Through the above technical solution, the multiple detachable first umbrella skirts 2 can be added or reduced as appropriate according to the actual situation, thereby adapting to cables of different lengths.

[0026] In use, first install terminal 5, then put sleeve 6 over the outside of terminal 5 until the bottom of sleeve 6 contacts the top of limit ring 4. Then manually rotate the self-locking screws 11 on both sides. Through the threaded connection, the corresponding clamping plate 8 moves into the sleeve 6 under the limit of slide rod 10. During the inward movement of clamping plate 8, the inclined surface of inclined block 12 can be pushed. Pushing inclined block 12 downward, the sliding of inclined block 12 outside limit rod 13 applies downward pressure to spring 14 and sealing ring 7 until the clamping plates 8 on both sides are completely clamped on terminal 5. The tight fit between terminal 5 and clamping plate 8 secures the sleeve 6, preventing it from loosening after prolonged use and consequently causing the sealing ring 7 to loosen. The downward pressure from the inclined block 12 and spring 14 ensures the sealing ring 7 seals the connection between terminal 5 and limit ring 4. Furthermore, the spring 14 adjusts the pressure of the sealing ring 7 based on its own stress, guaranteeing a consistently tight fit between the sealing ring 7 and the connection between terminal 5 and limit ring 4. This effectively prevents the sealing ring 7 from softening and deforming due to prolonged exposure to rain and sun. This leads to a failure of the seal at the connection between terminal 5 and the limiting ring 4, resulting in rainwater leakage during rainy days and causing discharge breakdown. This effectively improves the safety and service life of the device. The device can fix the sleeve 6 by clamping the installed terminal 5 with the clamping plate 8, effectively preventing the sleeve 6 from loosening after prolonged use, which in turn causes the sealing ring 7 to loosen, thus improving operational stability. Furthermore, the downward pressure from the inclined block 12 and the spring 14 ensures that the sealing ring 7 seals the connection between terminal 5 and the limiting ring 4. Additionally, the spring 14 will... Stress is used to adjust the pressure of the sealing ring 7, thereby ensuring that the sealing ring 7 always fits tightly against the connection between the terminal 5 and the limiting ring 4. This effectively prevents the sealing ring 7 from softening and deforming due to prolonged use and exposure to rain and sun, which could lead to failure of the seal at the connection between the terminal 5 and the limiting ring 4, resulting in rainwater leakage and discharge breakdown. This effectively improves the safety and service life of the device. The multiple detachable first umbrella skirts 2 can be added or removed as needed to adapt to cables of different lengths.
